Anti-climbing mechanism of high-pressure tower ladder stand

Abstract

The invention relates to an anti-climbing mechanism of a ladder stand, in particular to an anti-climbing mechanism of a high-voltage tower ladder stand. A ladder stand (10) and a high-voltage tower (14) are arranged at an interval; a plurality of plugging bulges (9) are arranged on the front surface of the plugging plate; sliding sleeves (4) are arranged at the four corners of the plugging plate respectively, four sliding rods (3) penetrate through the sliding sleeves respectively, the front ends of the four sliding rods are fixedly connected with the outer sides of the two side rods respectively, sliding clamps (5) are arranged on the lower portions of the two sliding rods on the upper portions of the four sliding rods of the two side rods of the crawling ladder and the upper portions of the two sliding rods on the lower portions of the four sliding rods of the two side rods of the crawling ladder respectively, and the front end of each front plate (23) is hinged to the rear end of a push-pull rod (2). The front ends of the four push-pull rods are divided into two groups and are hinged to the upper ends and the lower parts of two lock rods (6); lock holes B (31) respectively formed in the lower ends of the two lock rods and lock holes A (13) of the ladder stand are locked through padlocks (12); the ladder stand is blocked through the blocking protrusions of the blocking plate, and irrelevant personnel are effectively prevented from climbing the high-voltage tower.

Description

technical field [0001] The invention relates to an anti-climbing mechanism of a ladder, in particular the invention relates to an anti-climbing mechanism of a high-voltage tower ladder. Background technique [0002] The high-voltage towers that pass through the roadside in the city are responsible for the task of power supply in the city. Due to the aesthetic considerations, most of them are high-voltage towers with a steel pipe tower structure. For the convenience of construction and maintenance, a climbing ladder is provided on one side of the high-voltage tower. Climbing by irrelevant personnel, there are eye-catching promotional placards such as high-voltage danger on the ladder, usually without anti-climbing function, only the height of the lower end of the ladder is set at 1.5 meters, which has a certain degree of protection against children. Climbing effect, but it has no obvious effect on adults; in the news reports, there have been incidents of passers-by climbing h...

[0002] The high-voltage towers that pass through the roadside in the city are responsible for the task of power supply in the city. Due to the aesthetic considerations, most of them are high-voltage towers with a steel pipe tower structure. For the convenience of construction and maintenance, a climbing ladder is provided on one side of the high-voltage tower. Climbing by irrelevant personnel, there are eye-catching promotional placards such as high-voltage danger on the ladder, usually without anti-climbing function, only the height of the lower end of the ladder is set at 1.5 meters, which has a certain degree of protection against children. Climbing effect, but it has no obvious effect on adults; in the news reports, there have been incidents of passers-by climbing high-voltage towers for various reasons. When passers-by climb high-voltage towers, on the one hand, it will cause traffic paralysis. It will bring greater persuasion and rescue pressure to the police and firefighters; there are also a very small number of people with mental problems who will also climb high-voltage towers
