Self-locking and climbable cable trench cover plate

Abstract

The invention discloses a self-locking and climbable cable trench cover plate, and relates to the technical field of power equipment. The self-locking and climbable cable trench cover plate consists of a cable trench, a cover plate, stand columns, a bracket and a ladder, wherein the cover plate is arranged on the cable trench; the cover plate is provided with the stand columns and the bracket; a rotary shaft is arranged in each stand column; a pulling wire is arranged on the rotary shaft; an opening is formed in the wall of each stand column; a fixed clamp is arranged on one side of the opening; the bracket is connected with the ladder; one end of the bracket is arranged on the cover plate; one end of the bracket is connected with the ladder; one end of the ladder is connected with the bracket; and the other end of the ladder is fixed at the bottom of the cable trench. The self-locking and climbable cable trench cover plate is high in practicability, quite simple to install and use, and capable of reducing tool carrying amount of an electric power staff, effectively isolating and warning around the cable trench when the electric power staff is in operation in the trench, and improving operating safety and convenience.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of power equipment, in particular to a self-locking and climbable cable trench cover. [0003] 【Background technique】 [0004] As is well known, cable trenches are widely used in substations, social streets and living quarters. Cable trenches are arranged between each section of the cable trenches to facilitate daily maintenance and maintenance. The cable trenches will be covered with cover plates. The depth of the cable trench is different according to different needs. When maintaining the cable trench, the power personnel need to use a ladder when entering the deeper cable trench, so that the power personnel must carry the ladder with them, which not only causes a burden on manpower, but also affects work efficiency. At the same time, when maintenance personnel work in the cable trench, the cable trench cover is opened, which will cause inconvenience to pedestrians on the road, and even some pedestrians ...

AI Technical Summary

Problems solved by technology

[0004] It is well known that cable trenches are widely used in substations, social streets and living quarters. Cable trenches are set between each section of cable trenches to facilitate daily repairs and maintenance. The cable trenches are covered with cover plates. The depth of the cable trench is different according to different needs. When maintaining the cable trench, electric personnel need to use a ladder when entering a deep cable trench. In this way, the electric personnel must carry the ladder with them, which not only imposes a burden on manpower, but also affects work efficiency. At the same time, when maintenance personnel work in the cable trench, the cable trench cover is opened, which will cause inconvenience to pedestrians on the road, and even some pedestrians will accidentally fall into the cable trench if they are not careful, which will endanger the personal safety of pedestrians. Bringing hidden dangers, the current common method is to erect the obstacle warning poles carried around the cable trench after opening the cable trench cover for warning, but in this way, electricians need to carry multiple warning poles with them, which will also cause a burden on manpower , affecting work efficiency
