Abstract
An operation hoisting equipment hand-squeezing prevention device comprises an oil tube coupler, a hoisting suspension rope, a traveling block, two sets of hooks, two sets of suspension rings, clamps, bolts, hand guards, an oil tube suspension clamp and a wellhead device. The traveling block is connected with the hoisting suspension rope, the hooks are fixed to the traveling block, the suspension rings are connected to the hooks in a hanging mode, the hooks and the suspension rings are symmetrically arranged, the lower ends of the two suspension rings are buckled onto the oil tube suspension clamp in a symmetrical mode, the oil tube suspension clamp suspends the oil tube coupler and enables the oil tube coupler to be arranged on the upper end face of the oil tube suspension clamp, the oil tube suspension clamp is arranged on the wellhead device, the clamps, the bolts and the hand guards form a protective device, the hand guard is arranged on the clamp, and the clamps are fixed to one of the suspension ring through the bolts. In the process of operation, fingers of operation workers are protected by the protective device, the accident of hand squeezing can not happen even if two operators are asynchronous and the suspension rings jump, therefore, the accident that the operation workers are squeezed can be avoided, safe production can be achieved in the process of well drilling and well repair, and obvious social benefits are achieved.
Description
Technical field
The utility model is the equipment of the on-the-spot use of oil field drilling workover treatment, is operation lifting means anti-squeezing hand device.
Background technology
During the oil field drilling workover treatment, need to connect lifting means and pipe elevator with suspension ring, two suspension ring symmetries hang on travelling block, two suspension ring remove with travelling block, and two suspension ring lower end symmetries hang on pipe elevator, and pipe elevator fastens tubing coupling, tubing coupling bottom connected pipes post, therefore, suspension ring will bear the total weight of tubing string, and the total weight of tubing string reaches tens of tons.During operation, workman's hand is grabbed suspension ring, due to impossible Complete Synchronization, the position that the hand that adds again operating worker is grabbed suspension ring can not guarantee to be in place of safety, suspension ring cut to turn at sky and hold the moment of cutting and beat, the workman generally has little time hand is extracted out, workman's finger is squeezed between suspension ring and pipe elevator, thereby produces great personal injury accident.
Summary of the invention
The purpose of this utility model is to provide a kind of operation lifting means anti-squeezing hand device, and while guaranteeing the operating worker misoperation, the finger of operating worker can not be in hazardous area, can not occur to squeeze to hinder accident, prevents that the finger of operating worker from being squeezed off.
the purpose of this utility model is achieved in that and comprises tubing coupling, promote lifting rope, travelling block, hook, suspension ring, clip, bolt, handguard, pipe elevator, wellhead assembly, travelling block is connected with the lifting lifting rope, hook is fixed on travelling block, suspension ring are articulated on hook, hook, suspension ring are two covers and are symmetrical arranged, two suspension ring lower end symmetries are tipped on pipe elevator, pipe elevator hangs tubing coupling, make the tubing coupling seat on the upper surface of pipe elevator, the pipe elevator seat is on wellhead assembly, clip, bolt, handguard forms protective device, handguard is arranged on clip, clip is bolted on suspension ring.
The protective device that is comprised of clip, bolt, handguard is two covers, and symmetry is arranged on two suspension ring.
Distance between handguard and suspension ring is greater than 60mm.
The protective device that clip, bolt, handguard form and the distance between pipe elevator are greater than 200mm.
The beneficial effects of the utility model are: during operation, the protected device of the finger of operating worker is covering; the hand accident can not occur to squeeze yet even occur that two nonsynchronous situation suspension ring of operator are beated; can avoid the accident that operating worker crushes injury to occur; during drilling and repairing well, can keep the safety in production, have significant social benefit.
The accompanying drawing explanation
Fig. 1 is the assembled view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
as seen from the figure, embodiment of the present utility model comprises tubing coupling 1, promote lifting rope 2, travelling block 3, hook 4, suspension ring 5, clip 6, bolt 7, handguard 8, pipe elevator 9, wellhead assembly 10, travelling block 3 is connected with lifting lifting rope 2, hook 4 is fixed on travelling block 3, suspension ring 5 are articulated on hook 4, hook 4, suspension ring 5 are two covers and are symmetrical arranged, two suspension ring 5 lower end symmetries are tipped on pipe elevator 9, pipe elevator 9 hangs tubing coupling 1, make 1 of tubing coupling on the upper surface of pipe elevator 9, 9 of pipe elevators are on wellhead assembly 10, clip 6, bolt 7, handguard 8 forms protective device, handguard 8 is arranged on clip 6, clip 6 is fixed on suspension ring 5 by bolt 7.The protective device that is comprised of clip 6, bolt 7, handguard 8 is two covers, and symmetry is arranged on two suspension ring 5.Distance between handguard 8 and suspension ring 5 is greater than 60mm, and convenient finger is put into and operated.The protective device of clip 6, bolt 7, handguard 8 compositions and the distance between pipe elevator 9, greater than 200mm, have enough safe distances between assurance operator's finger and pipe elevator 9.
