Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and in particular relates to an overhead stable electrical cabinet. Background Art

[0002] The main function of an electrical cabinet is to provide a safe environment for accommodating and organizing various electrical equipment, including power distribution, control systems, instrumentation, etc. It is usually used to protect these devices from the influence of the external environment and ensure the reliability and stability of the system. The interior of the electrical cabinet usually contains various electrical components such as power switches, circuit breakers, relays, metering instruments, PLC (programmable logic controller), etc. These components are reasonably laid out and connected to form a complete electrical system for controlling, monitoring and distributing electricity. And it is widely used in various fields, including industrial production lines, power plants, power distribution systems, building electrical systems, etc. In industrial automation, electrical cabinets play a key role in the centralized control and management of electrical equipment.

[0003] In certain industrial scenarios, there are situations where electrical equipment needs to be moved or relocated frequently. The weight and design of traditional electrical cabinets may not be flexible enough in such environments, bringing some challenges to the layout and maintenance of the system. Traditional electrical cabinets usually adopt a sturdy metal or alloy structure, which ensures the strength and stability of the cabinet. However, this also causes the electrical cabinet to be relatively heavy, making it relatively difficult to frequently move or rearrange electrical equipment in industrial scenarios. Workers may need to invest more manpower and time to complete these tasks, which affects the layout efficiency of the entire system.

[0004] In addition, the maintenance of traditional electrical cabinets may also be affected. Due to the relatively closed structure of the cabinet, maintenance personnel may face a relatively narrow working space when inspecting or replacing equipment. This not only increases the difficulty of maintenance, but may also prolong maintenance time and have a certain impact on the availability of the system.

[0005] Furthermore, it can be concluded that in some industrial scenarios, electrical equipment may need to be moved or relocated frequently, and the weight and design of traditional electrical cabinets may not be flexible enough, affecting the layout and maintenance of the system.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0027] This solution achieves effective movement and positioning through the precise meshing of the worm and worm wheel, combined with the synergistic effect of the threaded sleeve, bearing seat and threaded column. The worm and worm wheel system can be started by turning the handle, so that the support body can be raised and lowered under the lifting and lowering action of the threaded column, thereby changing the height of the support body. When moving, the bottom height increases to improve passability, and when fixed, it decreases to improve stability.
