Description

Quick extracting tool of T type cable termination

Technical Field

The invention relates to the field of power grid distribution cable lines, in particular to a quick disassembling tool for a T-shaped cable terminal.

Background

The distribution cable line is composed of a 10 kilovolt or 20 kilovolt distribution cable, a ring main unit and a branch box. T type cable termination belongs to the cable and looped netowrk cabinet, branch box's connecting point. According to the 'distribution process standard of national grid company', in order to ensure the tight connection between the T-shaped cable terminal and the cable pile head insulating sleeve during installation, the contact surface is cleaned by cleaning paper, coated with silicone grease and then crimped.

When a power grid is transformed or a cable fault is processed, the T-shaped cable terminal is usually required to be detached and separated from the cable pile head insulating sleeve. At this moment, because the two are connected closely, traditional manual work is drawn directly and is drawn the method and waste time and energy, and is inefficient. Moreover, the rope pulling can damage the equipment panel, so that a crack is generated between the panel and the pile head, and even serious people can cause sulfur hexafluoride gas leakage.

Disclosure of Invention

The purpose of the invention is: the utility model provides a design a quick extracting tool of T type cable termination, adopts spiral push and plug-in separation mode, ensures to realize accurately fast that T type cable termination and cable pile head insulation support separate smoothly, reduces T type cable termination and cable pile head insulation support separation time, improves work efficiency, eliminates the rope simultaneously and draws damage, destruction that draw and cause equipment, promotes power supply reliability and economic nature.

The technical solution of the invention is as follows: the dismounting tool comprises a clamp, connecting rods, a chassis and a screw rod, wherein one ends of the two connecting rods are symmetrically and parallelly arranged on the clamp, the other ends of the connecting rods are symmetrically and parallelly arranged on the chassis, the screw rod is arranged at the center of the chassis, and the dismounting tool integrally forms a T-shaped cable terminal quick dismounting tool.

Furthermore, the clamp is of a two-section type or a three-section type, the tail end of the clamp is provided with a clamping seat, one clamping seat is provided with a bolt type clamping joint, and a bolt of the bolt type clamping joint is embedded into the grooves of the two aligned clamping seats.

Furthermore, the inner wall of the clamp adopts a groove type to be matched with a T-shaped cable terminal.

Furthermore, the top of the screw rod is provided with a hexagonal nut, and the bottom of the screw rod is provided with a circular bottom plate.

Furthermore, pressing plates are symmetrically welded on two sides of the base plate, and the connecting rod is installed on the base plate through the pressing plates and nuts.

Furthermore, the ratchet wrench also comprises a force application rod, wherein the force application rod comprises a handle and a ratchet wrench, and one end of the handle is provided with the ratchet wrench.

The invention has the advantages that:

1. the clamp has the function of transversely and tightly clamping the tail end of the T-shaped cable terminal in the clamp, so that the T-shaped cable terminal is firmly fixed.

2. A ratchet wrench adopting a force application rod is sleeved on a hexagonal nut of a screw rod, the force application rod is rotated, the screw rod is spirally pushed, a round bottom plate at the bottom of the screw rod abuts against a T-shaped cable terminal, the screw rod limits the longitudinal movement of the T-shaped cable terminal, the force application rod is pulled outwards at last, the screw rod assists a hoop to be linked, and the T-shaped cable terminal and an insulating sleeve are forced to be separated in the moving process of the screw rod in the direction perpendicular to a chassis.

3. Two connecting rods are symmetrically arranged on the hoop and the chassis in parallel, and the hoop and the chassis are connected into a whole, so that the whole linkage of the tool is ensured.

4. When the base plate ensures that the screw rod separates the T-shaped cable terminal, the separating acting force is always vertical to the base plate, and the force is saved.

5. The distance between the screw rod and the hoop is changed by unidirectional rotation force application of the force application rod, the round bottom plate at the bottom of the screw rod is abutted against the T-shaped cable terminal, and the T-shaped cable terminal and the insulating sleeve are finally separated.
