Description

A suspension bridge type insulating horizontal ladder

technical field

The invention relates to an insulating horizontal ladder, in particular to a suspension bridge type insulating horizontal ladder.

Background technique

With the development of economy and society, all kinds of electricity customers have higher and higher requirements for the continuous supply of electricity. On the other hand, various hidden risks faced by transmission lines are also multiplying, especially in special weather such as flood season. . It is a fast and effective way to restore power transmission by using insulation repair towers to erect tower collapse accidents of transmission lines caused by natural disasters. After the insulation emergency repair tower is erected and supports the wires, the operator enters the wires, and uses the horizontal ladder to install the relevant hardware by using the equipotential operation method. The existing horizontal ladder requires the operator to carry the insulating transmission rope for high-altitude transmission during use. This method has the following disadvantages: first, the operator needs to carry the insulation transmission rope when climbing the pole tower, which has a relatively large safety hazard; When using the transfer rope for transfer, there are many operators who need to participate, which brings certain difficulties to the operation organizers; third, when the horizontal ladder reaches the designated position of the insulation repair tower, it needs to be manually tied, and the operation time is longer.

Contents of the invention

In order to solve the above problems, the present invention provides a suspension bridge type insulating horizontal ladder used on the insulating repair tower.

The technical solution of the present invention is: a suspension bridge type insulating horizontal ladder, comprising: a horizontal ladder body and a rotating fixed body installed on the emergency repair tower;

The rotating fixed body includes an upper horizontal plate and a lower horizontal plate. Two fixed columns are arranged between the upper horizontal plate and the lower horizontal plate. on the fixed part;

The horizontal ladder body includes a first vertical bar, a second vertical bar and several cross bars arranged between the first vertical bar and the second vertical bar; one end of the horizontal bar is fixedly connected with the first vertical bar, and the other end is connected with the second vertical bar. The vertical bar is slidingly connected; the bottom ends of the first vertical bar and the second vertical bar are fixedly connected with chain hoops that can be bound to the fixed column, and both ends of the chain hoops are provided with fastening blocks. Fastening holes are arranged on the solid block.

Further, a plurality of sliding slots are provided on the second vertical bar, and the end of the horizontal bar connected to the second vertical bar is provided with a sliding block adapted to the sliding slots.

Further, the chain hoop includes an upper chain plate and a lower chain plate, and several elastic rollers are arranged between the upper chain plate and the lower chain plate.

Further, the side of the elastic roller close to the fixed column is provided with a T-shaped limit block;

The fixed column includes an upper column and a lower column. One side of the upper column and the lower column is hinged, and the side close to the upper column and the lower column is provided with a limiting groove; a gap is formed between the upper column and the lower column. A T-shaped limiting space adapted to the T-shaped limiting block.

Further, the lower horizontal plate is provided with two reinforcing ribs detachably connected with the vertical beam of the emergency repair tower.

Further, pull cords are provided on the first vertical bar and the second vertical bar.

Further, anti-slip lines are provided on the crossbar.

The suspension bridge type insulating horizontal ladder provided by the present invention fixes the rotating fixed body on the appropriate position of the emergency repair tower before erecting the emergency repair tower, then fixes the horizontal ladder body on the fixed column of the fixed body through chain hoops, and also fixes the insulating rope It is fixed on the proper position of the emergency repair tower and on the body of the horizontal ladder. During the erection of the emergency repair tower, the horizontal ladder is driven to stand up. When in use, the high-altitude workers only need to loosen one end of the insulating rope bound to the horizontal ladder, and rely on the insulating rope to operate the horizontal ladder to overlap the wire. In addition, because the horizontal ladder body is fixed on the fixed column of the fixed body through the chain hoop, the horizontal ladder can be rotated within a certain range, which is convenient for repairing different phase lines and is easy to use. The present invention avoids the operation links in which the workers need to carry the insulation transmission rope when climbing the pole tower, greatly improves the safety benefit; reduces the number of personnel participating in the operation, and reduces the difficulty of operation organization; when the suspension bridge type insulating horizontal ladder is used, only 1 It can be operated by one operator, which saves the process of passing the horizontal ladder by the ground operator, greatly saves the working time and improves the working efficiency; the horizontal ladder can be rotated to facilitate the repair of different phase lines.
