Description
Technical field
This utility model is related to power equipment maintaining fixture fields, and in particular to a kind of to change single insulator string for power equipment maintaining
When shackle.
Background technology
Power transmission lines overhauling works, it usually needs single insulator string is changed using Lever Blocks or double hook, and (shaft tower insulate
When sub- suspension type is tension double-string).During work, needs are used shackle and are connected with the yoke plate for being fixed on insulator two ends
Connect, be then connected again to complete replacing insulator work by shackle with Lever Blocks or double hook.
Existing shackle is generally comprised U-shaped main body and wears pin, wherein wearing pin passes across attaching nut after the opening of main body
Realize both connections.It is the field high altitude operation on shaft tower that single insulator string is changed due to power equipment maintaining, in main body and
During wearing the removing and installing of pin, nut is easy to drop, and causes the loss of nut to cause more the changing jobs for single insulator string cannot
Carry out；In addition main body and wear removing and installing for pin and need to rotate repeatedly nut, both hands operation reduces the efficiency for more changing jobs.
Utility model content
In sum, in order to overcome the shortcomings of prior art, technical problem to be solved in the utility model is to provide
A kind of shackle during insulator string single for power equipment maintaining replacing.
The technical scheme that this utility model solves above-mentioned technical problem is as follows：It is a kind of to change single string insulation for power equipment maintaining
The shackle of the period of the day from 11 p.m. to 1 a.m, including U-shaped main body and pin is worn, the pin of wearing is horizontally set with the open side in the main body, the opening of the main body
Side is provided with wears the first pin-and-hole and the second pin-and-hole that pin is passed through for described；Described one end for wearing pin is provided with more than its radial dimension of pin
Head, the other end for wearing pin are in the outside of the main body after sequentially passing through first pin-and-hole and the second pin-and-hole；
The inwall of second pin-and-hole is circumferentially uniformly provided with multiple mounting grooves, in the mounting groove is provided with spring, described
Spring is provided with steel ball away from one end of the mounting groove, and the position for wearing on pin and corresponding to the steel ball is provided with a circle with its phase
The draw-in groove of matching.
The beneficial effects of the utility model are：Avoid in main body and wear the connection of pin and drop with nut in unloading process,
The loss of nut is caused to cause more changing jobs for single insulator string carry out；In addition main body and the connection of pin is worn with dismantle need not
Nut is rotated repeatedly, work efficiency is improved.
On the basis of above-mentioned technical proposal, this utility model can also do following improvement.
Further, the draw-in groove is the arc-shaped caved in.
Using the beneficial effect of above-mentioned further scheme it is：It is easy to will wear and block in pin insertion main body or extract main body out.
Further, the mounting groove is provided with three.
Using the beneficial effect of above-mentioned further scheme it is：Steel ball both can reliably be blocked and wear pin, readily can take out again
Go out to wear pin.
Further, the head for wearing pin is provided with for mitigating the lightening hole of weight.
Using the beneficial effect of above-mentioned further scheme it is：On the premise of shackle intensity is ensured, the weight of shackle is reduced,
Mitigate the burden that shackle carries transfer.

Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, a kind of shackle when changing single insulator string for power equipment maintaining, including U-shaped main body 1 and wear pin
2, the pin 2 of wearing is horizontally set with the open side in the main body 1, the open side of the main body 1 be provided with for it is described wear that pin 2 is passed through first
Pin-and-hole 3 and the second pin-and-hole 4；Described one end for wearing pin 2 is provided with more than its radial dimension of plunger, the other end for wearing pin 2
The outside of the main body 1 is in after sequentially passing through first pin-and-hole 3 and the second pin-and-hole 4.The inwall circumference of second pin-and-hole 4
