Problems solved by technology

In the actual operation of power grid operation and maintenance, the common problems of high-voltage switchgear are that the handcart switch is inconvenient to operate, the guide rail is heavy, and it is difficult to carry. It takes two to three people to work together to slowly lift it up. The operation is time-consuming and laborious. Among them, the situation of unmanned supervision during work has increased potential safety risks, and some trolley guide rails do not have suitable lifting parts, which may also cause injuries to workers during the handling process.

Embodiment Construction

[0021] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0022] See Figure 1-3 , The present invention provides a technical solution: a high-voltage switch cabinet handcart switch guide rail, including a guide rail structure, a bracket mechanism and a pull rod 9. The guide rail structure includes two main rails 1 parallel in a plane and two main rails in the same plane. The inner parallel secondary rails 2, two secondary rails 2 are located inside the two main rails 1, the two ends of the secondary rail 2 are welded with beams 3, and the two ends of the beam 3 are welded with a main rail 1; The rigid connection of the beam 3 c...

Abstract

The invention discloses a high-voltage switch cabinet handcart switch guide rail. The high-voltage switch cabinet handcart switch guide rail comprises a guide rail structure, a bracket mechanism and apull rod; the bracket structure is installed in the middle of the guide rail structure, rollers are installed at the bottom of the bracket structure, and the pull rod is arranged at the handle end ofthe bracket structure. A worker can lift the guide rail structure off the ground by only operating the handle end; after the guide rail structure leaves the ground, the entire device only has the rollers at the bottom of the bracket structure in contact with the ground; so that the high-voltage switch cabinet handcart switch guide rail changes the sliding friction generated by the relative movement between the guide rail and the ground in the prior art to rolling friction; therefore, the friction is effectively reduced, and the work difficulty and risk are reduced.

Description

Technical field [0001] The invention relates to the related technical field of high-voltage electrical equipment, and in particular to a switch rail of a high-voltage switch cabinet handcart. Background technique [0002] High-voltage switchgear is the most frequently operated indoor equipment in the daily substation operation and maintenance work, and it is also a high-incidence equipment that causes personal injury and death accidents in the power grid. Therefore, the safety and accuracy of high-voltage switchgear operation is the basis for ensuring the safety of people, power grids, and equipment. In the actual operation of power grid operation and maintenance, the common problems of high-voltage switchgear are inconvenient operation of the handcart switch, heavy guide rails, and difficult handling. Two to three people are required to work together to lift it slowly. The operation is time-consuming and laborious, and sometimes the guardian must also participate. Among them, th...
