Abstract

The utility model discloses a portable overhead ground wire lifter through which the problem that the existing overhead ground wire lifters of transmission lines are inconvenient for carrying and limited by the types of towers. The portable overhead ground wire lifter comprises a U-shaped bracket, a steel pipe, ratchet wrenches and steel wire ropes; a hook is arranged in the middle of the upper part of the U-shaped bracket; holes are arranged on baffles at two sides of the U-shaped bracket so as to fixedly connect two rolling bearings; the steel pipe horizontally penetrates through the two rolling bearings; the steel pipe between the baffles at the two sides of the U-shaped bracket is fixedly connected with two ratchet wrenches with regulators; small grooves are arranged at positions of the steel pipe close to two ends; the steel wire ropes penetrate through the steel pipe from the small grooves; and hooks are arranged at the tail ends of the steel wire ropes. The portable overhead ground wire lifter is not limited by the types of towers and can be suitable for various towers; the operation is time-saving, labor-saving, simple and convenient; the used ratchet wrenches are smaller in volume and light in weight, can be put in a tool kit for carryon and can be operated by a single person; the labor intensity and the safety risk are reduced; and the work efficiency is improved.

Description

Portable overhead ground wire lifter
Affiliated technical field:
The utility model relates to a kind of Maintenance of Electric Transmission Line instrument, more precisely relates to a kind of bearing that promotes the transmission line overhead ground wire.
Prior art:
At present, being used to promote the more Work tool of transmission line overhead ground wire is that gin pole pulls chain block combination, DYQ12 type and DTG type overhead ground wire lifter.When adopting gin pole to pull chain block combination tool replacing overhead ground wire suspension clamp; Reasons such as, chain length heavier because of chain block self; Shaft tower inconvenience is carried up and down; The security risk of operation is than higher above alive circuit, and labour intensity is also bigger during work high above the ground, and operating efficiency is low; DYQ12 type overhead ground wire lifter is simple to operate, the moulding relative complex, and self is heavier, and shaft tower carries inconvenience up and down, and on shaft tower, inconvenience is installed, and has increased live line working labour intensity and security risk, influences operating efficiency; DTG type overhead ground wire lifter is relatively simple for structure, and good looking appearance is lighter, and it is also very simple to operate, and can reduce live line working labour intensity, security risk and increase work efficiency, but it can only be used for self-supporting steel tower, can't on cement pole, use.
Summary of the invention:
The purpose of the utility model is to overcome existing transmission line overhead ground wire lifting Work tool and carries inconvenience, receives the deficiency that the shaft tower pattern limits, security risk is high, labour intensity is big and operating efficiency is low; A kind of portable overhead ground wire lifter is provided; Simple in structure; Lighter, be easy to carry, easily operation.
The utility model is characterised in that: comprise U type support, steel pipe, ratchet spanner, steel wire rope, suspension hook is set in the middle of the top of U type support, at two rolling bearings of two side guards punching fixed connection of U type support, the steel pipe level is passed two rolling bearings; Steel pipe between U type support two side guards is fixedly connected the ratchet spanner of two band adjusters, has the rope stretching sulculus at steel pipe near the position at two ends, and steel wire rope passes steel pipe from the rope stretching sulculus; Described steel wire rope end is provided with hook.
Described rope stretching sulculus polishes smooth.
Described steel pipe two ends are provided with hold-doun nut and and cap.
Described hook has to lock and colludes.
As stated; The utility model is for ease of carrying in the shaft tower process up and down and reducing the live line working scope of activities; Adopt ratchet spanner to substitute traditional load and promote instrument; Described ratchet spanner has adjuster, not only can promote overhead ground wire, also can turn over turnback through adjuster and reduce overhead ground wire; Effectively control overhead ground wire only rise do not fall when guaranteeing to break ratchet spanner off with the fingers and thumb at every turn; Be provided with two ratchet spanneres; A ratchet spanner is when breaking off with the fingers and thumb; Another ratchet spanner is locked, and can effectively control the downward gravity of overhead ground wire self well, prevents that the ratchet spanner of breaking off with the fingers and thumb from causing overhead ground wire to fall after rise with middle steel shaft counter-rotating; When rotating with ratchet spanner and the resistance between support the right and left baffle plate, respectively weld a rolling bearing in the contact portion of U type support the right and left baffle plate and steel pipe respectively for steel pipe in the middle of reducing; For prevent that overhead ground wire from skidding off in the stressed lifting hook, hook is provided with to lock and colludes; For guaranteeing that hoisting wirerope has sufficient intensity, simultaneously the overhead ground wire of slinging is played the effect of second protection, the steel wire rope two ends all are provided with hook, adopt the form of double hanging point to promote overhead ground wire; For reducing steel wire rope when stressed and the friction between the steel pipe, reduce the wearing and tearing of steel wire rope, increase the service life, two rope stretching notches that steel pipe passed steel wire rope polish smooth; For the steel wire rope slippage steel pipe that prevents to tighten up, be provided with hold-down nut and and cap at the two ends of steel pipe.
Operation principle: utilize the double hanging point steel wire rope to hook the transmission line overhead ground wire, the handle through the rotating ratchet spanner tightens up steel wire rope and comes upwards to promote overhead ground wire.
The beneficial effect of the utility model: do not receive the restriction of shaft tower type, on all kinds of shaft towers; Time saving and energy saving in the operation, easy and simple to handle; The ratchet spanner volume that uses is less, in light weight, and the kit of can packing into is convenient to carry, and can the one man operation; Through repeatedly field test with improve and optimizate proof, can reduce labour intensity, security risk, increase work efficiency.
