Abstract

The utility model discloses a connecting and fixing device for moving a top drive of a drilling machine and a derrick rapidly. A section of guide rail at the lowest end of a top drive guiding rail is welded with a top drive conveying support which is fixedly provided with a clamping plate for inserting and connecting; two groups of connecting devices are arranged on two derrick cross beams at the lower section of the derrick, each group of connecting device is fixedly connected with a group of locking device, and a locking hook in the locking device is connected with the clamping plate by a locking pin shaft. For the connecting and fixing device, the top drive can ascend and descend along with the derrick, and can be moved together with the derrick, so that a large amount of disassembly work of the top drive can be reduced, the drilling machine conveying efficiency is improved, and the drilling machine conveying cost can be reduced.

Description

Movement drill top-drive and derrick are connected and fixed device fast

Technical field

The utility model belongs to the drilling equipment technical field, relates to a kind of quick movement drill top-drive and derrick and is connected and fixed device.

Background technology

In recent years, along with the World Oil Market sustainable development, intensified competition, each oily company and drilling company require more and more higher to rig moving time and cost of transportation; Each big drilling company has also all proposed to explicitly call for to the movement performance of rig both at home and abroad.Require rig to move fast, a collection of rig (being movement of rig host machine integral or drilling derrick, base independent movement respectively) of partly pulling or pull therefore occurred, adapted to the development of oil market to a great extent; But, since the top drive can't be on derrick secure fixation, need dismounting is driven on the top during each movement.The dismounting that drive on the top is work high above the ground fully, and the dismantlement work amount is big on the one hand, and there is a lot of security risks in work high above the ground on the other hand.

Summary of the invention

The purpose of this utility model provides a kind of quick movement drill top-drive and derrick is connected and fixed device, solved prior art since the top drive can't be on derrick secure fixation, need dismounting is driven on the top, the problem that waste time and energy, security risk is big during each movement.

The technical scheme that the utility model adopted is, a kind of quick movement drill top-drive and derrick are connected and fixed device, comprise top drive guide rail, the transport support welding is driven on top drive guide rail one section guide rail and top bottom, and the clamp that is installed with grafting usefulness on the transport support is driven on the top; Two derrick panels of derrick hypomere are provided with two groups of linkages, and every group of linkage is fixedly connected with one group of locking device, and the locking bail in the locking device is connected with clamp by the locking bearing pin.

Quick movement drill top-drive of the present utility model and derrick are connected and fixed device, its characteristics also are: every group of locking device comprises a locking bearing, the locking bearing is fixed on the derrick panel by a linkage, the outer face of locking bearing is provided with jackscrew, be welded with junction plate and be connected otic placode on the locking bearing, connect otic placode and be connected by bearing pin with locking bail.

Described every group of linkage comprises four double-screw bolts, pressing plate, locking nut, and junction plate and pressing plate are pressed against respectively on derrick panel two facades, and connects by four double-screw bolts, and the two ends of four double-screw bolts are equipped with locking nut.

The beneficial effects of the utility model are, can quickly and easily the top be driven to be fixed on the derrick, really reach the quick movement of rig, improve rig movement efficient, reduce rig movement cost, safe ready.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, Fig. 2, Fig. 3, quick movement drill top-drive of the present utility model and derrick are connected and fixed apparatus structure and are, what Fig. 1 showed is that drive in the derrick extreme lower position on the top, in derrick 17, be vertically arranged with top drive guide rail 16, top drive guide rail 16 drives 19 with the top and is slidingly connected, and the top is driven 19 and is connected with tourist bus 18 hooks, and top drive guide rail 16 one section guide rail and top bottom driven transport support 1 and welded, the clamp 2 that is installed with grafting usefulness on the transport support 1 is driven on the top, referring to Fig. 4; Two derrick panels 15 of derrick hypomere are provided with two groups of linkages 4, and every group of linkage 4 is fixedly connected with one group of locking device 3.Locking device 3 and linkage 4 are established the 4-6 group according to concrete field condition.

With reference to Fig. 5, every group of locking device 3 comprises a locking bearing 5, locking bearing 5 is fixed on the derrick panel 15 by a linkage 4, the outer face of locking bearing 5 is provided with jackscrew 6, be welded with junction plate 9 and be connected otic placode 7 on the locking bearing 5, connecting otic placode 7 is connected by bearing pin 10 with locking bail 8, locking bail 8 can be around bearing pin 10 rotations, when needs block the top when driving transport support 1, forward locking bail 8 to operating position, block and push up the clamp 2 that drives on the transport support 1, it is promptly lockable to plug locking bearing pin 11.
