Description

Technical Field

[0001] This invention relates to the field of automotive welding and conveying technology, and more particularly to a multi-track switching device for an overhead suspended trolley conveyor line. Background Technology

[0002] Currently, a track switching device is required in the conveyor line used for overhead suspended trolleys. The overhead suspended trolley can change its route through the track switching device, which can save layout space and improve production cycle and efficiency.

[0003] Existing track switching devices generally include a track, which is mounted on a track frame. Rollers are installed beneath the track frame, and these rollers engage with guide rails on a fixed beam. An electric actuator or motor drives a rack and pinion mechanism to roll the track frame along the guide rails, thus moving the track from one position to another to achieve track docking. The method of using an electric actuator to drive the track frame along the guide rails of the fixed frame has the following drawbacks: First, the guide rails must both guide and bear weight, resulting in low guiding accuracy and affecting track docking precision. Second, the large stroke of the electric actuator leads to a large space requirement. Finally, this method cannot stop at any arbitrary position, resulting in inaccurate track docking positions on the movable frame. Furthermore, the method of using a motor to drive a rack and pinion mechanism to roll the track frame along the guide rails introduces errors in docking angle control, affecting track docking precision. Therefore, the failure rate of currently suspended overhead trolleys during track switching is relatively high.

[0004] How to solve the above problems has become an urgent technical issue. Summary of the Invention
