Its main matching components are designed and manufactured according to the related regulations of API, and therefore can meet the related requirements of HSE.2.1 JC-70D DrawworksDrawworks drive JC-70D is part of the drive system of the Drilling Rig ZJ70D. The drawworks is not only used for making a trip, running the casing, controlling the weight on bit, dealing with the accident, lifting the core container, testing for oil, but also used for jacking and lowering of the mast and substructure. It is composed of two parts: the power device (including the input shaft) and the drawworks body. See drawing 2-1.Drawworks JC70D has the following features:1) Large powerThe drawworks is driven by two YZ08 electromotors (made in China), and parallel operated through the input axis of the power device. The rated input power can reach 1470kW.2) Good capability of speed adjustment and high efficiency of power13gears are also formed through the high speed and low speed clutches between the drive axis and the roller shaft.

The integrated power forms two gears through two chains between the input shaft and the drive shaft, and another two gears through two chains between the drive shaft and the drum shaft. So the drawworks has 2×2 gears in all. Besides, through the drive of one chain of the cathead shaft, the drive shaft makes the cathead shaft form two gears.It is the mechanical shift between the power input shaft and the drive shaft, and is the pneumatic tube clutch between the drive shaft and the drum shaft.gearshift, the drawworks must be stopped.The drawworks drive chains, which are in force feed lubrication, are equipped with the brake disk circulatory water cooling and water cooling electromagnetic vortex brake device. Functionally speaking, the drive of drawworks JC-70D is mainly composed of the following parts: see drawing 2-31) Drive part: imports, allocates and transmits the power, mainly including the assemblies of the input shaft, the drive shaft, the bailing drum shaft and the drum shaft, and the drive chains.2) Lifting part: is used for jacking up and lowering down the mast and the drilling floor, tripping in or out, running the casing, hoisting the load, making-up and shackling, etc.,178-bailing drum brake5) Brakeage system: is used to control the trip speed and the brake, mainly including the main brake and the auxiliary brake. The main brake of drawworks JC-70D is hydraulic tong disc brake, and the auxiliary brake is water cooling electromagnetic vortex auxiliary brake.6) Support part: is used for installing and fixing the components and parts of the drawworks, mainly including the substructure, the support and the guard.18electromagnetic vortex auxiliary brake, the anti-collision crown block device, the main brake system, the electric control system and the lubrication system.2.1.4 Main Brake System of the drawworksThe main brake system of JC-70D is adopted with the hydraulic disk brake.The hydraulic disc brake system consists of the part of the hydraulic control and the part of the hydraulic brake tong. The part of the hydraulic control, which is made up of a hydraulic pump station and an operation table, is the power source and the power control system, providing the necessary hydraulic pressure for the brake tong. The brake tong is the power executive system, providing the adjustable positive pressure for the main machine to accomplish the braking. The brake tongs include the work tongs and the safety tongs.Compared with the traditional belt brake, the hydraulic disk brake is characteristic for its large capacity of the brake torque, the steady effect of the brake, the small inertia of the brake secondary movement, the good adjustability of the brake force, the accuracy and flexibility of the brake and the convenience of the operation and the maintenance. The hydraulic system is safe for use with the simple and compact structure, the reasonable disposal and the reliable capability.2.1.4.1 Major Technical Parametersz Hydraulic control system19oil L-HM 20 for winter; N46 for summer)3) Rated flux for single pump 18L/min4) Volume of oil cylinder 80L5) Power of electrical motor 2×2.2kW6) Capacity of accumulator 4×6.3L7) Power of electric heating 1 KW8) Flux of cooling water 2m2/h9) Volume (length × width × height) 1160×960×1220 (mm)10) Weight 650kgz Normally open work tong1) Max positive pressure on single side N=75kN2) Effective working area of the piston A=12271.8mm23) Overall dimensions (outside diameter × length) φ165×380(max) (mm)4) Weight 210kgz Normally close safety tong1) Max positive pressure on single side N=75kN2) Max working gap of brake block δ≤1mm3) Effective working area of the piston A=12644.9mm24) Overall dimensions (outer diameter× length) φ230×420(max) mm5) Weight 235kg2.1.4.2 Working PrinciplesWork brake: control the positive pressure of the work tong on the brake disk through operated the control handle of the brake valve so as to provide an adjustable brake torque for the main machine, realizing the bit feed, adjusting the weight on bit and the speed of the trip.Emergency brake: in the emergency, press the red emergency brake button; all the work tongs and the safety tongs should get involved in the brake to realize the emergent brake. During the regular trip, this button is forbidden to press.Over-wind protection: when the load is hoisted to a certain position by the hook, but20emergency brake to prevent the collision with the crown block.Parking brake: when the drilling rig does not work or the driller is about to leave the work platform, pull down the parking brake handle, the safety tong brakes to prevent the slippery of the hook.See “Operation Manual of hydraulic disc brake device” for further information.2.1.5 Auxiliary Brake systemAuxiliary brake mechanism adopts DWS70 water cooling electromagnetic eddy current brake.Electromagnetic eddy current brake is a new type of auxiliary brake adapting to drilling rigs in ocean or on land, which utilizes electromagnetic induction principle to make brake without wearing. And this brake has the characteristics of large moment, long life span and simple operation and maintenance. Electromagnetic eddy current brake may decrease wearing of main brake greatly, lengthen the life spam of brake disc, and reduce labor intensity of drilling workers. During drilling, main brake is not used; the brake moment is adjusted only by changing magnetizing current to control the speed of placing down drill pipe. When the rotational speed slows down to 50 r/min, 75% of the maximum moment can be got, which can meet the demands of placing down drill pipe with heavy load.Technical parametersz Mode DWS70z Rated brake moment 110000N.mz Maximum magnetizing power 23kWz Weight 11000kg2.1.6 Anti-collision Crown Block DeviceThe function of the anti-collision device is that when the traveling system is hoisted to the limitative position, the emergency brake will stop the hoist of the traveling system through the caging device to prevent the collision with the crown block and guarantee the safety. There are three insurance systems for the anti-collision device of ZJ70D series drilling rigs. One is the wire line anti-collision device installed on a point of the upper segment of the mast, which will restrict the hoist of the traveling block. Another is the drawworks21Drawworks JC-70D is applied with the pneumatic over-wind valve device. The over-wind valve is installed above the roller and can be adjusted along the shaft. The length of the over-wind valve dog driver is adjusted according to the length of the coiled wire line on the roller when the traveling block is hoisted to its limit height (the traveling block is hoisted to 6-7m below the lower plane of the crown block girder). When the traveling block is at the limit height, the fast line touches the dog driver; the drum clutch discharges the air; the disk brake normally close tong works. Brake suddenly to hold the drum.Notice: Before the shift of duty every day, the over-wind valve rod should be pressed first to check whether the over-wind valve works regularly.After the use, the anti-collision relief valve must be pressed before hanging up the drum to loosen the brake tong and turn the rod of the over-wind valve to the vertical position.2.1.7 Traveling block digital display anti-collision1) Digital display anti-collision is new digital controller that can realize functions, such as displaying traveling block height, preventing the traveling block from colliding with the crown block and striking the table. It can display the height of any position of the traveling block hook from derrick floor 0-50m above. And it can warn at certain position and brake the drawworks. And it consists of programmable controller, digital display operation panel and coder. Drum bearing coder converts traveling block height into drum rotation amount. And it is sent to PLC for processing in the way of impulse and displayed on digital display operation panel.2) Up-going height is divided into two stages: the 1st is precaution stage with two branches signals: one branch goes to buzzer to provide sound alarm; the other branch is switch electric signal (normally open) that goes to SCR driller’s console entrance jack. The SCR system controls winch electric motor to slow down rapidly to 0 therefore realizes the traveling block soft stopping. The 2nd is emergency brake stage. It outputs switch electric signal (normally open) to disc brake electromagnetic valve to control disc brake for emergency brake.Down-going height is divided into two stages: the 1st is precaution stage, which sends signal to the buzzer for sound alarm to remind the driller of operating the brake valve. The223) System description*Input voltage: AC 220V±10% 50Hz*Measuring range: 0~50m (based on the drilling floor)* Display mode: digital display*Warning brake height: set according to reality4) Design and manufacture in accord with relevant power engineering standards. Factors such as explosion proof, shockproof, protection, fire proof are fully taken into account, which accords with safety operation requirement.2.1.8 Driller‘s cabinThe drilling operation is designed for sitting and the driller can control the operation console as a whole. The position of the control room is safe with broad sight view. The max value of the jack-up load of the mast and the substructure is signed at the points which are easy to be observed.Overall dimensions of Driller’s cabin: 2800×2200×2600 mmDesign features of the driller’s cabin:z Driller’s safety: The operation room is installed with the lever lock, which is convenient not only for the regular operation but also for the protection and escape in emergency.z Convenient for observation: It is convenient to observe the racking platform, the rotary table, the winch, the instrument and the whole drilling table.z Convenient for work: it is convenient to inspect and maintain all the operation boxes;the driller can do all the operations while sitting.z Reasonable disposal: the joints of the equipment are well considered, such as the pneumatic control operation box, the electric operation box, the top drive operation box, the drilling parameter numerical display, the hydraulic system operation, the hydraulic cathead operation, the electric numerical control anti-collision device, etc., and the installation position and the lead in joint of the of the industrial monitoring device.z Convenient for move and durable for use.Equipment and construction material:23the transportation protective cover into consideration) and the roof protective net.Equipment: swivel chair, blowout-preventive electric appliance (light), 1P explosion -proof single window air conditioner, loud speaker, rain brush, etc.2.1.9 Pneumatic Control SystemSee the schematic diagram of the drawworks pneumatic control system in drawing 2-6. The air source of the drawworks is provided by the air process device of the drilling rig: about 0.9MPa compressed clean air enters the drawworks control components and the executive components through the air receiver below the drawworks substructure.1) Control of drum high and low speedThe high and low speed of the drum is controlled by a 2-HA-2Z three-position four-way restoration operation valve. When the valve handle is at the middle position, the clutches of the high speed and low speed are both exhausting and declutched; when the valve handle is at the position of the high speed, the controlling air, provided from the 2-HA-2Z three-position four-way restoration operation valve, will open the ND12 two-position three-way normally close pneumatic valve of the high speed clutch of the drum in the drawworks substructure; at this time, the source air enters the ND12 two-position three way normally close pneumatic valve through the ND12 two-position three way normally open pneumatic valve; after the dredge, one part of the air enters the drum high speed clutch, and the other part is divided by the three-way and enters the ND5 dual-pressure valve. When the handle of 2-HA-2Z three-position four-way restoration operation valve is at the high speed position, the low speed clutch is in the status of exhausting. If the air enters the high speed end while the low speed end is yet not to finish exhausting, the exhaust of the low speed end is also divided by the three-way and provided to the ND5 dual-pressure valve. The dual-pressure valve will open when there are signals at both control orifices. The compressed air flows from the ND5 dual-pressure valve, through the ND5 shuffle valve to control the ND12 two-position three-way normally open pneumatic control valve, so that the ND12 two-position three-way normally open pneumatic control valve is closed and both the high and low speed clutches exhaust, preventing the two clutches of the high and low speed hanged up together. When the handle of the 2-HA-2Z three-position four-way restoration24。
