Description

Technical Field

[0001] The present application relates to the technical field of auxiliary tools for installing high-voltage cabinets, and more specifically, to a mobile anti-drop device for high-voltage cabinets in railway substations. Background Art

[0002] High-voltage distribution cabinets are used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems. During the construction of high-voltage cabinets in railway substations, we found that a long deep groove is usually reserved in the base of the substation equipment. The groove can be used for heat dissipation at the bottom of the high-voltage cabinet or transformer, and can also be used for drainage to prevent water from soaking the high-voltage cabinet. The movement and adjustment of high-voltage cabinets and transformers can easily cause personnel and / or equipment to fall into the groove, and the construction process is time-consuming and labor-intensive, affecting the progress of the project. In order to solve this problem, a simple and practical tool is designed to solve the safety risks and construction efficiency problems in the movement and adjustment of high-voltage cabinets.

[0003] In view of this, we propose a mobile anti-falling device for high-voltage cabinets in railway substations. Utility Model Content

[0006] 2. Technical solution

[0007] The technical solution of the present application provides a mobile anti-falling device for a high-voltage cabinet in a railway substation, comprising a telescopically adjustable support frame, the support frame comprising a U-shaped first support plate and a second support plate slidably inserted into the U-shaped opening of the first support plate, the first support plate and the second support plate are detachable, both ends of the first support plate and the second support plate are fixed with a strap, the first support plate is symmetrically provided with a first bull's eye ball universal ball seat that can be raised and lowered, and the second support plate is provided with a second bull's eye ball universal ball seat that can be raised and lowered.

[0008] By adopting the above technical solution, the first support plate and the second support plate are placed in the groove, and the support frame is supported and fixed in the groove through the extension adjustment of the first support plate and the second support plate. When it is necessary to carry and move the high-voltage cabinet equipment, the first bull's eye ball universal ball seat and the second bull's eye ball universal ball seat are raised to protrude from the support frame and be coplanar. The equipment is supported on the first bull's eye ball universal ball seat and the second bull's eye ball universal ball seat, which can reduce the friction at the bottom of the high-voltage cabinet to facilitate the adjustment of the placement position of the high-voltage cabinet. When personnel are required to stand on the support frame to operate the high-voltage cabinet, the first bull's eye ball universal ball seat and the second bull's eye ball universal ball seat are stored in the support frame to prevent personnel from slipping or falling into the groove.

When the staff stands on the support frame, the first strip plate and the bull's eye ball universal ball are stored in the first strip groove, and the insertion rod is inserted into the slot at the upper end. When it is necessary to adjust the installation position of the high-voltage cabinet, the insertion rod is disengaged from the upper slot by pulling the pull rod outward, the tension spring generates an elastic rebound force, and then the first strip plate is lifted upward to insert the insertion rod into the lower slot.
