Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0017] A stud extractor such as figure 1 shown. It includes a column, and the lower end of the column is fixed with a base 1 . The main body of the column includes an upper column 2.2 and a bottom column 2.3, the bottom column 2.3 is a hollow steel pipe, the base 1 is fixed under the bottom column, the upper column 2.2 is plugged into the inner hole of the bottom column 2.3, the upper column 2.2 and The bottom column 2.3 should be closely matched, but it can move up and down relative to each other. Several telescopic positioning holes 2.1 are set on the upper column 2.2 and the bottom column 2.3. After adjusting the height of the column, use positioning pins to insert them into the upper column 2.2 and the bottom column 2.3. The positions of the upper column 2.2) and the bottom column (2.3) are fixed in the telescopic positioning hole 2.1. The upper end of last col...

Abstract

The invention discloses a puller for a wiring pile, and belongs to tools used in an electric system. According to the puller for the wiring pile, a lever which is adjustable in height is hinged to the upper end of a stand column, a lifting end of the lever is connected with a pair of embracing pliers thorough two steel wire ropes, the pair of embracing pliers is composed of a pliers block I, a pliers block II and a pin bolt, the pliers block I, the pliers block II and the pin bolt are connected in a hinged mode, the inner end of the pliers block I and the inner end of the pliers block II are jaws which are used for tightly embracing the wiring pile, the two steel wire ropes are connected on two sides of the pliers block I and the pliers block II respectively, a cotter which is used for preventing the pin bolt from falling off is arranged on the pin bolt, and bayonet columns which can clamp the wiring pile are further arranged on the side face of the lever. By means of the puller for the wiring pile, the wiring pile can be easily pulled out, the problem that the wiring pile is difficult to pull out is solved, and damage to the wiring pile cannot happen.

Description

technical field [0001] The invention relates to a tool, in particular to a tool used in a power system for pulling out a wiring pile buried underground. Background technique [0002] In order to ensure safety, when the power supply system is repaired and maintained, it is necessary to connect the ground wire to the repaired and maintained devices after a power failure. The access of the ground wire is to drive a wiring pile into the ground, and then connect the ground wire (copper wire) led down from the equipment to the wiring pile. The wiring pile is a copper rod with a length of about 1.5m. The lower end of the wiring pile is provided with a cone tip, and the upper part of the wiring pile is provided with a hole for connecting the ground wire. To facilitate ground connection. The deeper the wiring pile is driven into the ground, the greater the safety effect of the ground wire. When the wiring pile is buried in the ground, it can be driven in with a sledgehammer, but i...
