Abstract
The invention relates to a multifunctional insulator pin extractor. At present, the inconvenience for carrying and operating is caused because pin extracting tools for extracting an R pin and a W pin are simultaneously put on when an insulator is replaced. The multifunctional pin extractor is characterized by comprising a rod body, wherein the front end of the rod body is matched and connected with a pin extracting head bent towards the side direction of the rod body, the outer end of the pin extracting head is provided with an inserting convex block, and the pin extracting head is provided with a top plane. The rod body is a screw driver with a grab handle, the part on a driver body of the screw driver, which is adjacent to a driver head, and the part of the driver body of the screw driver, which is adjacent to the grab handle, are provided with threads; and the inner end of the pin extracting head is provided with a pipe sleeve integrally connected with the pin extracting head, and the inner wall of the pipe sleeve is matched with the threads on the driver body of the screw driver. The two pin extracting tools and another screw driver needing frequently using are improved and synthesized to form a pin extractor capable of simultaneously extracting two kinds of pins, thus the multifunctional insulator pin extractor is convenient for carrying and can improve working efficiency.
Description
Technical field
The present invention relates to change in a kind of ultra-high-tension power transmission line the write off instrument of insulator, the sub-split-pin device of especially a kind of multifunction insulating.
Background technology
In recent years, owing to reasons such as damage to crops caused by thunder or circuit are aging gradually, the insulator self-destruction rate on the circuit increases, and the workload that causes changing insulator is bigger.Because the insulator of the old circuit of part adopts the W pin to connect, and the insulator of new line adopts the R pin to connect, the staff need wear the write off instrument that is applicable to these two kinds of pins simultaneously when changing insulator, make troubles to work.A kind of R pin write off specific purpose tool profile commonly used at present is big, is bending at the both ends of the body of rod, and out-of-shape can not directly be inserted Pi Cezhong, generally is to use aluminium wire system to hang over above the skin volume, causes carrying inconvenience, and when work, drops easily.And a kind of mode of getting W pin is to use the specific purpose tool pincers of pulling pin, and the W pin that uses the pincers of pulling pin to take out deforms easily, and the W pin after the distortion also drops to ground easily from steel emits, influence the safe operation of circuit, ruptures easily if older W sells to go back.Another kind of mode is that the mode that adopts the spanner tail end to push away the W pin is come write off, because the tail end of spanner is curved, when pushing away the W pin, makes the W pin that deformation takes place easily; The W pin of other poor flexibility is also directly released steel by spanner easily and is emitted, and cause to drop to ground, but operational readiness is lower.
Summary of the invention
The present invention is directed to the defective that prior art exists, provide a kind of easy to use, improve the sub-split-pin device of multifunction insulating of changing insulator work efficient, use this split-pin device to change insulator, effectively the minimizing instrument carries, and makes things convenient for write off work to carry out.
For this reason; The present invention takes following technical scheme: a kind of multifunctional pin extraction device, it is characterized in that comprising a body of rod, and the front end of the said body of rod connects a write off head to the bending of body of rod side direction; The outer end of said write off head forms inserts projection, and described write off head has the plane, top.Projection matches in order to the annulus with R pin upper end, projection is inserted in the annulus of R pin upper end and takes out the R pin so that through the body of rod write off head is applied active force.Only need prop up the W pin when getting the W pin with the plane, top of write off head and apply longitudinal force, make the W pin deviate to get final product from another through hole of steel cap, the write off head on plane is difficult for making the W pin that deformation takes place.The write off head is detachable the connection with the body of rod, is easy to carry.
The described body of rod is the screwdriver of band lever; Be provided with screw thread in abutting connection with the position of cutter head and in abutting connection with the position of lever on the cutter hub of said screwdriver; The inner of said write off head is provided with the pipe box that links to each other with its one, and the screw thread on the inwall of said pipe box and the said screwdriver body matches.Pipe box and write off are integrally welded, can effectively improve the bulk strength of write off head, and when off working state, pipe box revolved put on the screw thread of lever, easy to carry, safety, the body of rod can be used as screwdriver and carried out routine operation this moment.
Described write off head is " protruding " font, and the write off head of this shape can better match with the annulus of R pin upper end, is convenient to implement write off work.
Beneficial effect of the present invention is embodied in: two kinds of write off instruments are needed the frequent screwdriver that uses to improve to synthesize the split-pin device that a kind of while can get two kinds of pins with another kind of, and not only easy to carry, can also increase work efficiency.

The specific embodiment
A kind of multifunctional pin extraction device as depicted in figs. 1 and 2; Mainly constitute by the write off that matches as the screwdriver of the body of rod 13 and and screwdriver 1; Screwdriver is made up of lever 3 and the cutter hub 5 that is fixed on the lever 3 and extend forward; Cutter hub 5 front ends are processed cutter head 4, have screw thread 6 in abutting connection with the position of cutter head 4 and in abutting connection with the position of lever 3 on the cutter hub 5.Write off 1 has plane 12, top; Its integral body is " protruding " font; Its outer end forms the projection 2 that inserts R pin upper end annulus 9, and the inner of write off 1 is provided with the pipe box 7 of a perpendicular and one welding, the inwall of pipe box 7 form screw thread and with cutter hub 5 on the screw thread 6 that forms match.
When getting the W pin; In the through hole that only needs write off 1 is filled in the insulator steel cap 11; The baseplane of write off 1 and the W pin in the insulator steel cap 11 are offseted (referring to Fig. 3 A), apply longitudinal force then and push away the W pin and make it skid off (referring to Fig. 3 B), accomplish write off from another through hole; When getting the R pin, the projection 2 of write off 1 outer end is inserted the annulus 9 interior (referring to Fig. 4 A) of R pin upper end, exert oneself downwards (referring to Fig. 4 B) takes out R pin 8 again.
In the time need not using split-pin device, pipe box 7 is cooperated with screw thread 6 in abutting connection with the lever position, and make write off 1 inwardly, sleeve pipe 7 has reduced the length of whole split-pin device outwardly, easy to carry, safety.
