Description

Technical Field

[0001] The present invention relates to the technical field of switchgear assembly production lines, and more specifically, to a switchgear assembly flexible production line. Background Art

[0002] In the power grid, switchgear is an important device used to control, protect and isolate circuits. The reliable operation of switchgear is directly related to the safe, stable and efficient operation of the power grid. If a switchgear fails, the circuit may not be properly controlled and the fault may not be isolated in time, leading to serious consequences such as large-scale power outages. Therefore, the production, installation, commissioning and maintenance of switchgear need to be carried out in strict accordance with relevant standards and specifications to ensure its performance and reliability.

[0003] Switchgear includes different types of cabinets such as high-voltage switchgear, low-voltage switchgear, center cabinet, ring network cabinet, gas-filled cabinet, solid insulation cabinet, etc. Switchgear is produced by different cabinets and components through assembly line processing. For example, the gas-filled cabinet is an indoor AC high-voltage gas-insulated metal-enclosed switchgear. The gas-filled cabinet seals and installs high-voltage electrical components in a metal shell filled with insulating gas to achieve functions such as control, protection and measurement of high-voltage circuits. It is mainly used in power systems, industrial fields, commercial buildings, etc. to ensure the safety of electricity use in production.

[0004] In the existing production of inflatable cabinets, the split-structure gas cabinet body and the base cabinet are mainly assembled and then assembled. Since the inflatable cabinet body is heavy, it needs to be transported with the assistance of conveying equipment during assembly. Commonly used conveying equipment includes conveyor belts and conveyor rollers. The inflatable cabinet body is transported by the conveying device to complete the assembly, assembly, storage and other processing operations in an orderly manner. However, the existing inflatable cabinet assembly of switchgear can only hoist the cabinet base from the storage station to the assembly station one by one. The separate hoisting is time-consuming, resulting in low production efficiency. In addition, when the cabinet is assembled and assembled, assembly parts such as screws and nuts often fall off. When the parts fall onto the conveyor belt or conveyor roller, it will affect the normal transportation of the cabinet. When the cabinet moves, it is easy to jam the main conveying equipment, causing the cabinet to tip over, resulting in accidents, and there are safety hazards.

[0005] When assembling the switchgear, it is also necessary to use a pneumatic wrench to assemble and lock the screws, bolts and other parts of the cabinet assembly. A large number of pneumatic wrenches are needed for batch assembly operations. The pneumatic wrenches need to be connected to the air supply device through connecting pipes. The connecting pipes connecting the various pneumatic wrenches are scattered on the ground, causing a messy production site, affecting walking and transportation, reducing production efficiency, and being prone to accidents, which is not conducive to safe production.

[0006] In view of this, it is necessary to develop a switchgear production technology solution that can ensure production safety, facilitate transportation and assembly operations, and effectively improve production efficiency to solve the problems encountered in the processing and production of the above-mentioned existing switchgear.
