Abstract

The utility model discloses an isolating switch hoisting device which settles the following problems in mounting or detaching an isolating switch: time and labor waste, and higher safety hazard. The isolating switch hoisting device comprises a channel steel fixing board (8) which is arranged on the top of a cement rod (10). A column base (13) of the column (12) is connected with the channel steel fixing board (8) through bolts (9). The top end of the column (12) is provided with a shaft (6) in a vertical direction and a power assisting bearing (7). The external surface of the power assisting bearing (7) is fixedly connected with a horizontal cantilever beam (11). A pin (5) is arranged at the outer end of the horizontal cantilever beam (11). A U-shaped ring (4) is hoisted on the pin (5). A fixed pulley (3) is hoisted on the U-shaped ring (4). One end of a rope (2) on the fixed pulley (3) is connected with the isolating switch (1). The isolating switch hoisting device has the following advantages: high reliability and high convenience in mounting on the cement rod, shortened time for mounting the isolating switch, and high suitability in use in maintenance operation of power transmission lines.

Description

Isolation switch lifting device

technical field

The present invention relates to a hoisting device used in the construction of transmission lines, in particular to a hoisting device for hoisting isolating switches on power transmission towers.

Background technique

In the construction or maintenance of transmission lines, disconnectors are indispensable equipment. When installing or removing the isolating switch, it needs to use a lot of manpower and material resources. Due to the limitation of the geographical conditions of the transmission line, it is inconvenient to use cranes and other equipment when installing or removing the isolating switch. It can only be done by manpower, which is time-consuming and laborious. And there is a big security risk.

Contents of the invention

The invention provides a hoisting device for an isolating switch, which solves the problems of time-consuming and labor-intensive installation and removal of the isolating switch and great potential safety hazards.

The present invention solves the above technical problems through the following technical solutions:

A hoisting device for an isolating switch, comprising a cement pole, on which a channel steel fixing plate is arranged on the top of the cement pole, the lower end of the upright column is fixedly arranged on the upright base, and the upright base is connected with the channel steel fixing plate through bolts. The top of the shaft is provided with an up and down vertical shaft, and a power-assisted bearing is arranged on the shaft. A horizontal cantilever beam is fixedly connected to the outer surface of the power-assisted bearing. A pin is arranged on the outer end of the horizontal cantilever beam, and a U The fixed pulley is hooked on the U-shaped ring, and one end of the rope on the fixed pulley is connected with a disconnect switch, and the other end of the rope on the fixed pulley is pulled by the ground operator.

The channel steel fixing plate is fixed on the upper end of the pole top of the cement pole by a hoop.

The invention is reliable and convenient to install on the cement pole, shortens the installation time of the isolating switch, has a high one-time assembly rate, and is especially suitable for use in the maintenance work of power transmission lines.

Detailed ways

A disconnector hoisting device, comprising a cement pole 10, a channel steel fixing plate 8 is arranged on the top of the cement pole 10, the lower end of the column 12 is fixedly arranged on the column base 13, and the column base 13 is fixed to the channel steel by bolts 9 The plates 8 are connected together, and the shaft 6 in the vertical direction is arranged on the top of the column 12, and the booster bearing 7 is arranged on the shaft 6, and the horizontal beam 11 is fixedly connected to the outer surface of the booster bearing 7. The outer end of 11 is provided with a pin 5, a U-shaped ring 4 is suspended on the pin 5, the fixed pulley 3 is hooked on the U-shaped ring 4, and one end of the rope 2 on the fixed pulley 3 is connected with a disconnector 1. The other end of rope 2 on the pulley 3 is towed by ground operator. The hoisting device is fixed on the top of the cement pole, and the horizontal cantilever beam can be rotated arbitrarily in a 360-degree space, which facilitates the assembly of the isolating switch 1 and saves manpower and material resources for on-site work.

The channel steel fixed plate 8 is fixed on the pole top upper end of the cement pole 10 by the hoop, as long as the hoop is opened, the hoisting device can be assembled and disassembled easily.
