Mechanical anti-dropping device
The invention discloses a mechanical anti-dropping device. The mechanical anti-dropping device comprises a fixed anti-dropping device bracket, wherein an anti-dropping hook is hinged to the anti-dropping device bracket; a hook-shaped part for supporting a vehicle loading plate is arranged at the bottom of the anti-dropping hook; the hook-shaped part of the anti-dropping hook is further provided with a connecting shaft; the connecting shaft is rotationally connected with a reset overhead hook; the reset overhead hook is longer than the hook-shaped part of the anti-dropping hook; the reset overhead hook and the connecting shaft are provided with torsion springs; a micro-switch mounting plate is arranged on the anti-dropping hook close to the reset overhead hook; a micro-switch which can be triggered by the reset overhead hook is arranged on the micro-switch mounting plate. By adopting the mechanical anti-dropping device, the defects of easiness in breakage of an electromagnet and unreliable quality in the conventional anti-dropping device are overcome; the improved anti-dropping device is safer and more stable; meanwhile, the electromagnet is not used anymore, so that the cost is reduced.
