Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] see Figure 1-5 As shown in the figure, the present invention provides an electric maintenance ladder used in a wet and slippery environment after rain. The two ends of anti-skid bar 1 are connected with the inboard of support frame 2 by fixed mode, and the lower end of described distance-adjustable anti-slip bar 1 is equipped with pedal bar 3 and is parallel to each other, and the inboard of described support frame 2 and foot bar The two ends of 3 are fixedly connected, and the end of the support frame 2 is embedded with a foot 4 .

[0023] The distance-adjustable anti-skid bar 1 includes a fixed block 11, a rotating block 12, a stepping column 13, an elastic cable fixed plate 14, an elastic cable 15, a rotary switch cover 16, and an anti...

Abstract

The invention relates to an electric power overhaul ladder used in a wet and slippery environment after rain. The electric power overhaul ladder structurally comprises distance adjusting anti-slidingrods, a supporting frame, pedal rods and bottom feet; the two ends of the distance adjusting anti-sliding rods are fixedly connected with the inner side of the supporting frame; the pedal rods are mounted at the lower ends of the distance adjusting anti-sliding rods and are parallel to the distance adjusting anti-sliding rods; and the inner side of the supporting frame is fixedly connected with the two ends of the pedal rods. Through deformation of the distance adjusting anti-sliding rods, the treading distance of the top of the electric power overhaul ladder can be adjusted, and thus the situation that the moving amplitude of the top of the electric power overhaul ladder is excessively large, consequently swinging is generated, and then the risk is caused is avoided; and after deformation, through pulling of an elastic cable, the surface of an anti-sliding block is attached to the surface of an telegraph pole, friction force of the distance adjusting anti-sliding rods during supporting is increased, thus the distance adjusting anti-sliding rods provide stable supporting force for the electric power overhaul ladder when erected on the telegraph pole, the top of the electric power overhaul ladder is prevented from sliding on the wet telegraph pole surface after the rain, and a strong guarantee is provided for the safety of overhaul personnel.

Description

technical field [0001] The invention relates to an electric maintenance ladder used in a slippery environment after rain, and relates to the field of electric maintenance ladders. Background technique [0002] Electric maintenance ladder, a classification of climbing ladders, is used for erection and maintenance when power equipment fails. The structure is mostly made of high-resistivity insulating materials to prevent current conduction during maintenance and cause life-threatening to maintenance personnel. [0003] However, power failures are prone to occur in thunderstorm weather. After the rain, the surface of the power equipment utility pole becomes smooth under the infiltration of rainwater, which reduces the friction coefficient of the utility pole surface. The part supported on the surface of the utility pole slides under the action of rainwater, which makes the erection of the maintenance ladder unstable and poses a danger to the maintenance personnel. [0004] The...
