By technique scheme, also comprise assist brake, described assist brake adopts water cooled electromagnetic eddy current brake, and assist brake is connected by the axle drive shaft of tooth clutch with the cylinder other end.
By technique scheme, also comprise emergency mechanism, described emergency mechanism comprises emergent motor, retarder and emergent tooth clutch, and emergency mechanism is installed in one end of winch input shaft by emergent tooth clutch.
In casing drilling operation, when needs high tap position works, throw off the first air tube clutch, winch power by and winch Power output beam warp versatile spindle on car transmission gearbox drives winch input shaft to move, hang conjunction second air tube clutch, the 3rd air tube clutch, the high tap position of winch can be obtained; When needs low-grade location works, throw off the second air tube clutch on high-grade speed reduction gearing, the 3rd air tube clutch, winch input shaft drives the input end of low-grade speed reduction gearing to move, and hangs conjunction first air tube clutch, can obtain the low-grade location of winch.
Technique effect acquired by the present invention is compared with prior art: 1, gear of the present invention reduces, and designs simplification, overcomes the shortcoming needing buty shifting when existing machinery winch makes a trip, make operation simpler, effectively improve winch driving efficiency, and then improve operating efficiency, reduce energy consumption.2, owing to being single casing drilling when casing drilling rig creeps into, do not need to promote thribble, derrick height reduces, and the master rotor of supporting winch holds rope amount to be reduced, when diameter of cylinder and wirerope diameter constant, the corresponding reduction of length of cylinder.The reduction of drum length is conducive to cylinder row rope on the one hand, not easily occurs stinging rope, disorder cable situation; On the other hand winch volume is reduced, designs simplification, oad reduces, and weight is corresponding to be alleviated, and reduces floor area, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1
,the present invention includes winch input shaft, Downshift mechanism, braking mechanism and emergency mechanism four part.And the band winch axle in car transmission gearbox drives winch input shaft 13 to move by versatile spindle, described Downshift mechanism comprises low-grade speed reduction gearing, high-grade speed reduction gearing, and the input shaft 13 of winch is connected with the input end of low-grade speed reduction gearing, high-grade speed reduction gearing respectively by sprocket wheel chain; Low-grade speed reduction gearing is made up of tween drive shaft 17, air tube clutch 1, sprocket wheel 14, sprocket wheel 16, sprocket wheel 18, sprocket wheel 2 and chain, and low-range reduction mechanism is connected with the axle drive shaft of cylinder 3 one end by air tube clutch 1; High-grade speed reduction gearing is made up of tween drive shaft 19, air tube clutch 9, air tube clutch 6, sprocket wheel 11, sprocket wheel 10, sprocket wheel 12, sprocket wheel 20, sprocket wheel 8 and chain, and high-grade reduction gear is connected with the axle drive shaft of cylinder 3 other end through air tube clutch 9, air tube clutch 6; Winch brake mechanism comprises major-minor brake, main brake adopts two groups of hydraulic disc brakes 4,5, two groups of hydraulic disc brakes 4,5 are separately positioned on the two ends of winch drum 3, assist brake adopts water cooled electromagnetic eddy current brake 7, adopts tooth clutch to connect between assist brake 7 and the axle drive shaft of the cylinder other end.For the object of safe operation, in input shaft one end, emergency facility 15 is set, emergency facility 15 comprises emergent motor, retarder and emergent tooth clutch, when mair motor break down or cisco unity malfunction time, start emergency facility 15, drive Downshift mechanism by emergent tooth clutch, reach the object promoting maximum drill string weight, ensure downhole safety and operator safety, and the emergent operation such as derrick telescoping, movable drilling tool can be realized.
