Abstract

The invention discloses a portable overhead grounding-wire raiser, and solves the problems that the overhead grounding-wire raiser of the existing power transmission line is inconvenient to carry, and is restricted by the pole/tower type, etc. The portable overhead grounding-wire raiser comprises a U-shaped supporter, a steel pipe, ratchet spanners and steel-wire ropes, wherein a lifting hook is arranged in the middle of the upper part of the U-shaped supporter, two rolling bearings are fixedly connected by punching baffle plates on two edges of the U-shaped supporter, and the steel pipe horizontally penetrate through the two rolling bearings. The two ratchet spanners with adjusters are fixedly connected on the steel pipe between the two baffle plates on the two edges of the U-shaped supporter; small grooves are arranged in positions adjacent to two ends of the steel pipe, and the steel-wire ropes penetrate through the steel pipe; and the a hook is respectively arranged at the tail ends of the steel-wire ropes. The portable overhead grounding-wire raiser disclosed by the invention is not restricted by the pole/tower type, can be applicable to various poles and towers, is time-saving and labor-saving, and is simple and convenient to operate; the adopted ratchet spanners has smaller volume and light weight, can be put into a tool kit to be convenient to carry and can be operated by one personnel; and the labor intensity and the safety risk are reduced, and the working efficiency is improved.

Description

Portable overhead ground wire lifter
Affiliated technical field:
The present invention relates to a kind of Maintenance of Electric Transmission Line instrument, more precisely relate 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, 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 use on cement pole.
Summary of the invention:
The objective of the invention is to overcome that existing transmission line overhead ground wire promotes that Work tool carries inconvenience, is subjected to the restriction of shaft tower pattern, security risk height, labour intensity is big and operating efficiency is low deficiency, a kind of portable overhead ground wire lifter is provided, simple in structure, lighter, be easy to carry, easily operation.
The invention is characterized in: 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 side guards of U type support fixedly connected two rolling bearings that punch, the steel pipe level is passed two rolling bearings; The ratchet spanner of fixedly connected two the band adjusters of steel pipe between U type support two side guards has the rope stretching sulculus in the position at the close two ends of steel pipe, 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 mentioned above, the present invention adopts ratchet spanner to substitute traditional load and promotes instrument for ease of carrying in the shaft tower process up and down and reducing the live line working scope of activities, and described ratchet spanner has adjuster, not only can promote overhead ground wire, also can turn over turnback and reduce overhead ground wire by adjuster; 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, can effectively control the downward gravity of overhead ground wire self well, prevent 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 by the rotating ratchet spanner tightens up steel wire rope and upwards promotes overhead ground wire.
Beneficial effect of the present invention: be not subjected to 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.
