Handrail base assembly and safety fence for transformer substation

Abstract

The invention discloses a handrail base assembly and a safety fence for a transformer substation. The handrail base assembly comprises a base of a cylindrical structure and at least three supporting plates, all the supporting plates are annularly distributed on the bottom face of the base at intervals, handrail holes allowing handrails to be inserted are formed in the upper surface of the base, mounting long grooves are formed in the positions, corresponding to all the supporting plates, of the bottom face of the base in a concave mode, and the mounting long grooves extend along the horizontalplane. One ends of the mounting long grooves in the length direction are provided with opening parts, the supporting plates partially protrude out of the side face of the base in the radial directionfrom the opening parts, and the supporting plates are mounted in the mounting long grooves and can selectively slide in the length direction of the mounting long grooves so as to change the length, protruding out of the opening parts of the mounting long grooves, of the supporting plates. The depth of the mounting long grooves is equal to the thickness of the supporting plates. The supporting plates are contracted in the length direction of the mounting long grooves, the length, extending out of the base, of the supporting plates is shortened, and a contact area between the handrail base assembly and the ground is reduced to adapt to the flatness of the ground.

Description

technical field [0001] The invention relates to the technical field of protective fences, in particular to a railing base assembly and a safety fence for a substation. Background technique [0002] A safety fence is usually installed in the substation, through which the staff is guided to the working place and the range of activities of the staff is limited, so as to prevent the staff from entering the electrified area by mistake. [0003] At present, the safety fence of the substation generally includes a base, a railing arranged on the base, and a fence body connected to the railing. In order to ensure the stability of the safety fence, the base has a certain weight (about 15kg). When installing and installing the fence, take out a certain number of railings, fence bodies and bases from the safety tool room to the site and install them. When collecting the safety fence, put the fence, railings and base back into the safety tool room. In order to facilitate the handling an...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the small size of the base, the windproof performance of the safety fence is poor, and the safety fence is often blown when the wind blows, thus posing a greater safety hazard;

[0006] 2. In the prior art, the bottom of the base is designed to be flat, and the stability of the safety fence is poor when the ground is uneven. It is necessary to adjust the position of the base on the ground to place the base stably
