SUSPENDED TRACK CONVEYING SYSTEM FOR AUTOMOBILE MANUFACTURING WORKSHOP

摘要

Provided is a suspended track conveying system for an automobile manufacturing workshop. The system comprises a track (11) and a suspended conveying vehicle. The track (11) is provided with multiple intercepting cross rods (12). The suspended conveying vehicle comprises a framework (1), a primary suspension column (10), an emergency braking mechanism (5), a first axle (31), a second axle (32), rollers (2), a speed reduction sleeve (4), a gearbox (6), an electric motor (7) and a controller (9). The emergency braking mechanism (5) comprises a secondary suspension column (51), a placement plate (52), a hydraulic cylinder (534), a limiting tube (56) and an oil pump (531). An upper surface of the hydraulic cylinder (534) is provided with a first oil port (532) and a second oil port (533), and the hydraulic cylinder (534) is internally provided with a piston, a second piston rod (535) and a first piston rod (536), with a movable end of the second piston rod (535) being connected to a speed reduction claw (55). The emergency braking mechanism further comprises an emergency braking rod (54), with a bottom end of the emergency braking rod (54) entering the interior of the limiting tube (56). The system can rapidly reduce the speed of a suspended conveying vehicle to zero, so as to avoid a collision between suspended conveying vehicles and avoid a workpiece from falling down, thus improving the process safety.
