Abstract
The utility model discloses a pistol-type pin puller applied to pulling off the cotter pin from an insulator of a transmission line. The pistol-type pin puller adopts the structure that a front barrel and a rear barrel are connected through a connecting piece; a wrench is hinged with the connecting piece; a pistol handle is welded below the rear barrel; the hook rod of a draw hook penetrates through the front barrel and the wrench, and is propped against a spring arranged in the rear barrel; a hook head is arranged at the front end of the draw hook; and a U-shaped clamping groove is formed at the front end of the front barrel. The utility model can reduce the labor intensity of the operating personnel, improve working efficiency and ensure working safety.
Description
Technical field
The utility model relates to a kind of hand-operated tools, the R type split pin on the insulator of the transmission line of electricity that is applied to choose, especially a kind of pistol type pin extractor.
Background technology
At present, the part composite insulator that uses on the transmission line of electricity and the spring catch of NGK porcelain insulator are R type pin, big and do not have special use to retract the instrument of R shape spring catch in the operation because of this spring catch elasticity, general use hand vice are firmly chosen or are firmly pounded out from the big opening part of steel cap with spanner, especially at the charged for replacement composite insulation period of the day from 11 p.m. to 1 a.m, the operating personnel must climb on the shaft tower cross-arm and operate, distance between insulator steel cap and the cross-arm is less, relatively more difficult when using hand vice or spanner handle to retract spring catch, the hand of also damaging easily.
Under the normal condition, the specification of the split pin of insulator and himself situation are had nothing in common with each other, need the staff to handle the various situations that may occur, choose or relatively waste time and energy with hand vice with the mode that spanner is pounded out, the staff has consumed muscle power greatly on shaft tower, have influence on following work.Because Work tool manufacturer lacks on-the-spot practical experience, fail to produce the convenient and practical instrument that is fit to workman's operation, if run into the situation of overexertion in the course of work, may cause coming off of hand vice or spanner, even can cause the high-altitude of insulator to come off, gently then lose the Work tool material, heavy then cause ground handling personnel's injures and deaths.
The utility model content
The technical problems to be solved in the utility model provides a kind of operating personnel's of reduction labour intensity, improve operating efficiency, guarantee the pistol type pin extractor of job safety, and it adopts lever linkage device to realize the labor-saving effect.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of pistol type pin extractor, its structure is that the preceding gun barrel that is provided with is connected through connector with the back gun barrel, spanner is articulated on the connector, below the gun barrel of described back, be welded with the small of the stock, the shank of drag hook passes preceding gun barrel, spanner and withstands on the spring of being located in the gun barrel of back, and the front end of drag hook is a gib head; The front end of gun barrel offers the U-shaped draw-in groove before described.
Further improve, also be provided with the adjusting bolt in the rear end of above-mentioned back gun barrel.By regulating the pretightning force that bolt comes regulating spring.
Adopt the beneficial effect that technique scheme produced to be: 1, to adopt lever principle in the structure, frictional force by spanner and shank spurs drag hook, make the operating personnel extract R shape spring catch very easily, and the utility model can be provided with different length according to need of work, reduce operating personnel's the degree of bending over, needn't re-use significantly to bend over to move and finish choosing of spring catch, thereby reduce labour intensity.
2, R type spring catch of dismounting needed about one minute time spent in the original operation, used the utility model only to need general about 2 seconds, had improved operating efficiency greatly.
3, in the job engineering, needn't worry coming off of spring catch and power tool, guarantee workman's safety.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the utility model partial sectional view;
Wherein, 1, preceding gun barrel; 2, connector; 3, back gun barrel; 4, regulate bolt; 5, the small of the stock; 6-1 is a shank, and 6-2 is a gib head; 7, spanner; 8, U-shaped draw-in groove; 9, spring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the similar pistol of the utility model shape, it utilizes lever principle, by stirring spanner, finishes choosing of spring catch thereby spur drag hook.Before gun barrel 1 fixedly connected connector 2 and preceding gun barrel 1, connector 2 and back equal firm welding between the gun barrel 3 between the gun barrel 3 by a connection piece 2 with the back.Be hinged with spanner 7 on connector 2, spanner 7 is provided with one can hold the hole that shank 6-1 passes through.Be provided with compression spring 9 in the inside of back gun barrel 3, finish resetting of drag hook by the elastic force of spring 9, drag hook is made up of shank 6-1 and gib head 6-2.Back gun barrel 3 rear ends have been threaded and have regulated bolt 4, regulate the elastic force size of bolt adjustable springs 9.At the supporting U-shaped draw-in groove 8 that has of the fore-end of preceding gun barrel 1, this U-shaped draw-in groove 8 can block R shape spring catch during work.Also have one section breach on the preceding gun barrel 1, can move for drag hook.
Under normal circumstances, because spring 9 effects, spanner 7 is in open mode, and operating personnel aim at the required spring pin of extracting to spanner 7 positions that hand is placed on during use, pull spanner 7 then, have promptly easily realized pulling out the work of spring catch.Can be according to the pistol type pin extractor of various shaft tower types and insulator model design different size and size, its length also can be changed and be designed as requested, to satisfy the requirement of various working environments.
Claims (2)
