Problems solved by technology

[0003] In the prior art, clamps are usually used to clamp the lower end of the insulator string to lift the hanging glass insulator string to the overhead line, and it is easy to shake left and right in the air during the lifting process, which is difficult to control
In addition, in the prior art, the workers apply force at high altitudes to lift the insulator strings to high altitudes. Operations at high altitudes are not only inconvenient for applying force and lifting, but also have certain risks.

Embodiment 1

[0023] Such as figure 1 As shown, the hanging glass insulator string lifting system includes a fixed rod 12, a first take-up and pay-off device 14, a second take-up and pay-off device 15, an insulator string fixture 16 and two fixed pulleys 17, and the fixed rod 12 is fixed on the wire One end of the cross arm 20 on the pole tower, the two fixed pulleys 17 are fixed on the fixed rod 12, and the first take-up and pay-off device 14 and the second take-up and pay-off device 15 are all arranged on the ground and include a bracket and a fixed Take-up and pay-off reels on the stand.

[0024] Two first connection ropes 18 are wound on the take-up and take-off reel of the first take-up and take-off device 14, which are connected with the insulator string fixture 16 through the two first connection ropes 18; the insulator string fixture 16 Two second connecting ropes 19 are also connected on the top, and one end of the two second connecting ropes 19 is connected to the insulator strin...

Embodiment 2

[0026] Such as figure 2 and image 3 As shown, the hanging glass insulator string fixture includes a first fixture 1 and a second fixture 2, the first fixture 1 and the second fixture 2 are in the shape of a semicircle, that is, the center has a semicircular hollow structure, and the first The fixture 1 and the second fixture 2 are installed together in the manner of two semicircular hollow structures adjacent to each other, so that the two semicircular hollow structures form a circular mounting hole for fixing the hanging glass insulator string; the first fixture Both ends of the first fixture 1 and the second fixture 2 are bent outward, and a mounting ear 3 is formed at both ends of the first fixture 1 and the second fixture 2, and there are 4 mounting ears 3 in total. The first fixture 1 The mounting ear 3 corresponding to the second fixture 2 is movably connected by the connecting shaft 4, that is, the mounting ear 3 can slide left and right on the connecting shaft 4 (th...

Embodiment 3

[0030] On the basis of Embodiment 2, in the hanging glass insulator string fixture in this embodiment, the two mounting ears 3 of the first fixture 1 are also provided with a limit rod 9 on the side facing the second fixture 2, so The two mounting ears 3 of the second fixture 2 are provided with a through hole 10 corresponding to the size and position of the limit rod 9, the limit rod 9 is passed through the through hole 10, and the end of the limit rod 9 is threaded. Connect with stop nut 11. In this embodiment, setting the limit rod 9 is mainly to keep the first clamp 1 and the second clamp 2 on the same horizontal plane, and further strengthen the stability of the first clamp 1 and the second clamp 2 on the horizontal plane.

Abstract

The invention discloses a lifting system for hanging glass insulator strings, which comprises a fixed rod, a first take-up and release device, a second take-up and release device, an insulator string fixture and two fixed pulleys, the fixed rod is fixed at one end of the cross arm, and 2 A fixed pulley is fixed on the fixed rod, and the first take-up and release device is connected to the insulator string fixture through the first connecting rope; the insulator string fixture is also connected to two second connecting ropes, and the other ends of the two second connecting ropes are Each winds around a fixed pulley and winds on the second take-up and pay-off device. When the lifting system of the present invention is used to lift the insulator string clamp, the insulator string clamp is pulled tightly by the first connecting rope and the second connecting rope from the bottom and the upper direction, so that the insulator string can be sent to the high altitude stably and quickly, which can solve the problem of In the prior art, there is a problem that the insulator string is shaking in the air when it is lifted, and it is more convenient and safe to operate the second take-up and release device on the bottom surface to lift the insulator string, and it has the advantages of convenient use and strong flexibility.

Description

technical field [0001] The invention relates to the technical field of power line maintenance, in particular to a lifting system for hanging glass insulator strings. Background technique [0002] The insulator is the main body of power transmission line insulation. Its purpose is to suspend the wire and keep the wire insulated from the tower and the earth. It should have high mechanical strength, good insulation performance, not be affected by sharp changes in strength, and resist natural erosion and aging. features. The material of the insulator generally adopts porcelain and toughened glass, and synthetic materials are also useful. Suspension insulators are often assembled into strings in transmission lines with a voltage level of 35KV and above. Suspension insulators generally form insulator strings and are used on lines with different voltage levels. At present, the insulators produced in my country are divided into two types: ordinary type and anti-pollution type. Te...
