Safety ladder for cable maintenance platform

Abstract

The invention discloses a safety ladder for a cable maintenance platform. The safety ladder comprises a herringbone ladder frame, the ladder frame comprises four ladder legs, the ladder legs are provided with fixing foot pads for stabilizing the ladder frame, the fixing foot pads are provided with grooves for accommodating the ladder legs, the side surfaces of the fixing foot pads are provided with fixing holes and fixing rods, through holes corresponding to the fixing holes are formed in the side faces of the ladder legs, the fixing rods penetrate through the fixing holes and the through holes to achieve connection between the ladder legs and the fixing foot pads, mounting holes and stabilizing rods penetrating through the mounting holes are arranged on the two sides of each fixing hole, buckles are arranged at the two ends of each stabilizing rod, and the buckles are used for connecting the stabilizing rods with the cable maintenance platform. The safety ladder has the beneficial effect that the safety ladder has higher stability.

Description

【Technical field】 [0001] The invention relates to a safety ladder used for a cable maintenance platform, and belongs to the technical field of safety ladders. 【Background technique】 [0002] With the continuous economic growth, the rapid development of urban power grids, and the requirements of modern cities for power supply reliability and environmental beautification, the number of cable lines put into operation is increasing rapidly. High-voltage cable lines are usually responsible for important power transmission tasks in urban networks. [0003] At present, during the maintenance work of the terminal head of the cable terminal tower, because the position of the cable head is relatively high, the staff standing on the maintenance platform cannot reach the maintenance position, and need to use a safety ladder to carry out the climbing operation. However, the existing safety ladders are usually made of insulating materials, which makes the overall safety ladder relatively...

AI Technical Summary

Problems solved by technology

However, the existing safety ladders are usually made of insulating materials, which makes the overall safety ladder relatively heavy and difficult to carry, which will increase the travel burden of the staff. In addition, because the cable inspection platform is formed by steel bars, there are many holes on the platform, making The safety ladder is difficult to fix, and usually the staff need to spend a lot of time to fix the safety ladder, but because the contact area between the ladder foot and the platform is greatly reduced, its stability is extremely poor, and the staff will move a lot when climbing. It will cause the safety ladder to shake or even fall, which is very unsafe
