Description

Technical Field

[0001] This utility model relates to the field of tooling vehicle technology, specifically a mobile tooling vehicle used for maintenance of overhead trolleys. Background Technology

[0002] The aerial monorail shuttle system (hereinafter referred to as the aerial shuttle) is a suspended monorail shuttle system. It uses a track fixed in the air, with equipment suspended below the track to transport materials, thus avoiding ground space occupation and transporting materials in the air. Because the aerial shuttle system operates in the air, the inspection and maintenance of the aerial shuttle equipment becomes a key consideration. Generally, if the aerial transport line is not high, maintenance personnel can directly perform maintenance work on the aerial shuttle equipment on the track using scaffolding or ladders. Alternatively, a dedicated lifting mechanism can be designed along the track to lower the aerial shuttle equipment to the ground for maintenance and inspection.

[0003] The aforementioned maintenance method using elevated equipment for on-rail inspection is suitable for production tasks with a single vehicle and single rail. When multiple vehicles are transported on the same rail, on-rail maintenance will cause the entire conveyor line to suspend operations, significantly impacting the overall transport schedule. Furthermore, maintenance and inspection work performed at height carries a certain risk of falls. In addition to the above on-rail maintenance methods, in most cases, specialized lifting equipment is designed on the track to lower the on-rail aerial trolley to a suitable height for worker operation for maintenance and inspection. This method effectively solves the problem of maintenance and inspection work affecting the main line transport and reduces the risks associated with workers working at height. However, since the aerial trolley is a suspended device, its structural characteristics prevent it from being placed directly on the ground when it is detached from the track for maintenance. Typically, when the aerial trolley is lowered to the maintenance height using the lifting equipment, workers can directly perform maintenance work from the lowered position. However, this operation carries certain risks, and the lifting mechanism must have sufficient load-bearing stability. Therefore, there is an urgent need for a mobile tooling vehicle for aerial trolley maintenance to solve the aforementioned technical problems. Utility Model Content
