Abstract

The utility model substation terminal wiring spanning ladder includes insulating brackets, rollers and a platform. The insulating brackets are four, and the four insulating brackets form a trapezoidal structure. The top of the four insulating brackets is equipped with a platform. The two ends of the platform are provided with curved roller direction grooves. The rollers are placed on the platform, and the two ends of the rollers are inserted into the roller direction grooves and fixed by locking screws. Because the utility model has the direction groove of the roller and can be locked, it increases the versatility in the direction facing the line. The utility model can effectively avoid the occurrence of electric shock accidents caused by the fault of the power grid on the wall of the substation to the wiring personnel. Because the utility model is equipped with a pulley on one side of the insulating support, it can be moved by the pulley after the rolling ladder is put down after use, which can save working time and improve work efficiency. The utility model is made of high-strength insulating material, and has light weight and high strength.

Description

Spanning escalator used for substation terminal wiring

technical field

The utility model relates to a tool used for erecting wires from 220 kV and 66 kV transmission lines to substation terminals, in particular to a spanning escalator used for substation terminal wiring.

Background technique

When the traditional 220 kV and 66 kV transmission lines are erected to the terminal of the substation, the wires will cause varying degrees of damage to the outer wall of the substation and the power grid on the wall, or even break the power grid. The erection of spanning frame is poor in economy and cannot stay overnight to prevent bad intrusion, and other measures cannot achieve good results.

Utility model content

The technical problem to be solved by the utility model is to provide a 220 kV and 66 kV transmission line to a substation terminal for erecting wires across the escalator. The escalator can be used in any substation, saving working time and improving work efficiency.

In order to solve the problems existing in the prior art, the technical solution adopted by the utility model is:

The spanning escalator used for substation terminal wiring includes insulating brackets, rollers and platforms. There are four insulating brackets, and the four insulating brackets form a trapezoidal structure. Platforms are installed on the top of the four insulating brackets. The end is provided with a curved roller direction groove, the roller is placed on the platform, and the two ends of the roller are inserted into the roller direction groove and fixed by locking screws.

Four pulleys are installed on one side of the insulating support.

The advantages and effects that the utility model has are:

The utility model includes a roller carrying wires, an insulating bracket, and a platform with a direction groove. The direction groove can make the direction of the rollers arbitrarily adjusted, and the locking screws on both sides of the roller can fix the direction that the rollers face so as to be perpendicular to the wires. The angle to carry the erected wire. Increased versatility in line-facing orientation thanks to wheel orientation slots and lockability. The utility model can effectively avoid the occurrence of electric shock accidents caused by the fault of the power grid on the wall of the substation to the wiring personnel. Because the utility model has all types of wires, it increases the versatility in the carrying capacity. Because the utility model is equipped with a pulley on one side of the insulating support, it can be moved by the pulley after the rolling ladder is put down after use, which can save working time and improve work efficiency. The utility model is made of high-strength insulating material, and has light weight and high strength.
