Universal circuit breaker trolley guide rails

Abstract

The invention discloses universal circuit breaker trolley guide rails. The number of the trolley guide rails (1) is two. Each of the trolley guide rails (1) is divided into two sections, wherein one section is a planar or approximately planar oblique plane, and the other section is an oblique plane. Convenience is brought to down sliding of a circuit breaker trolley by utilizing the oblique planes. A positioning device (2) is arranged on the upper surface of one of the trolley guide rails (1), circuit breaker trolley wheels (3) are embedded into the positioning device (2), sliding ways (6) are formed in the adjacent side walls of the two trolley guide rails (1), sliding rails (7) are arranged on the sliding ways (6), and groove-shaped sliding ways (6) are formed in the sliding rails (7). The universal circuit breaker trolley guide rails have good universality, completely meet daily operation pf various types of circuit breaker trolleys and are small in size, light in weight, convenient to move and lay, regular in appearance, convenient to arrange and place, simple and attractive.

Description

technical field [0001] The invention belongs to the technical field of a guide rail for a trolley of a general circuit breaker, and in particular relates to a guide rail for a trolley of a general circuit breaker. Background technique [0002] Nowadays, a large number of high-voltage switch cabinets are used in substations, and the high-voltage switch trolleys inside are very heavy. In order to ensure that they can bear the weight of the trolleys, the manufacturer’s supporting trolley guide rails are made of pure steel, which is heavy and has a large area. Generally, it is difficult for a single operator to move them. , bumps are prone to occur during the moving process, and there is no positioning block at the connection between the trolley guide rail and the high-voltage switch cabinet, it is difficult to completely dock, and most of them need the assistance of the guardian; there is no buffer groove at the tail of the trolley guide rail, and there is a steel plate thicknes...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a universal circuit breaker trolley guide rail to solve the problems in the above background technology that due to the difference in breaking capacity, the volume of handcart circuit breakers is different, and the guide rails corresponding to different specifications are difficult to achieve fixed swing in the high-voltage chamber. There are various types and sizes of storage and guide rails, and the versatility is not good.
