Embodiment 1

[0034] Embodiment 1: As a specific embodiment, please refer to figure 1 , the limiting groove 2 is a through hole running through the top and bottom of the special-shaped top plate 4, and the pin 5 is slidably fitted with the through hole; the outer edge of the special-shaped top plate 4 can be connected with the connecting bolt 10 The outer circles are in contact.

[0035] Get the length of pin post 5 to be greater than the depth of the through hole, which passes through the hole and partially exposes the left pincer 8, the outer edge of the movable end 42 of the special-shaped top plate 4 is flush, the left pincer 8 and the right pincer In the process of gradually reducing the angle between 6, since the outer edge of the movable end 42 is against the outer circle of the connecting bolt 10, the fixed end 41 will rotate with the movement of the right pliers head 6, so that the movable end 42 is opposite to the connecting bolt 10. The top is getting tighter and tighter, so tha...

Embodiment 2

[0039] Embodiment 2: As a specific embodiment, please refer to figure 2 with image 3 , the limiting groove 2 is a notch groove located at the bottom of the special-shaped top plate 4, and the bottom of the notch groove is slidably matched with the upper end of the pin removal column 5.

[0040] Such as figure 2 with image 3 As shown, the notch groove is only one end of the groove with a notch, which is for the convenience of cooperating with the pin removal column 5. First, the inner hole of the closed end of the R-shaped spring pin 3 is placed on the pin removal column 5, and then the pin removal column 5 is removed from the notch groove. Push the end into the notch groove.

[0041] As a further optimization, see figure 2 with image 3 , the movable end 42 is provided with a notch limiting hole 11 cooperating with the outer circle of the connecting bolt 10, and the center distance between the notch limiting hole 11 and the pin removal column 5 is the same as that be...

Abstract

The invention provides an R type spring pin removal tool, and belongs to the technical field of power maintenance tools. The R type spring pin removal tool comprises pliers as well as a special-shaped top plate and a pin removal stud matched with an inner hole in the closed end of an R type spring pin; the pin removal stud is located on a left plier head, and one end of the special-shaped top plate is hinged to a right plier head of the pliers; the other end of the special-shaped top plate is matched with the excircle of a connecting bolt, and the pin removal stud is matched with the special-shaped top plate slidably; the pin removal stud and the special-shaped top plate are located on the same side of the right plier head and the left plier head; through operation of the pliers, the included angle between the left plier head and the right plier head of the pliers is decreased, and the special-shaped top plate is matched with the connecting bolt; and the R type spring pin is removed from the connecting bolt through reaction force provided by the connecting bolt. The R type spring pin removal tool provided by the invention has the advantages of the simple structure, low cost, timeand labor saving, easy operation and improvement of working efficiency, and the danger of high-altitude falling during removal of the R type spring pin is avoided; the safety is improved, and the R type spring pin removal tool has good promotion prospects in overhead line construction.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance tools, and more specifically relates to an R-shaped spring pin removal tool. Background technique [0002] During the construction of the line erection, the connection between the power components and the cross arm and the suspension insulator is completed by connecting bolts. Equipped with anti-backlash R-type spring pin. Owing to be to make above-mentioned R-type spring pin corrode outdoors by wind and sun, need to replace the R-type spring pin that has been corroded regularly. [0003] At present, the staff use needle-nose pliers to clamp the closed end of the R-type spring pin to disassemble. It takes several times to remove an R-type spring pin before pulling it out from the connecting bolt. If the force is too small, the R-type spring cannot be removed. The pin is removed from the connecting bolt, and the R-type spring pin will pop out and fall from a high altitude if th...
