Problems solved by technology
[0003] When the above-mentioned lifting platform is in use, due to the influence of factors such as lack of oil in the hydraulic cylinder, broken chains or wire ropes, aging or bursting of oil pipes, and unexpected midway stop of the platform, it is easy to cause the chain or wire rope to loosen when the oil cylinder goes down. The potential safety hazard that causes the platform to hang in the air may eventually cause the platform to suddenly fall and cause a safety accident
[0004] For other lifting platforms that are not driven by hydraulic cylinders, the above-mentioned safety accidents may also be caused by factors such as the aging of motors and other devices, the breakage of chains or wire ropes, etc.

The invention discloses a lifting platform anti-dropping device. A lifting platform is driven to lift in a wellhole by a driving unit and a driving wheel; the lifting platform anti-dropping device comprises a sleeve, a movable part and an elastic element, wherein the sleeve is fixedly arranged on the lifting platform; the movable part is movably arranged in the sleeve in a penetrating way, is located at the connecting end of the sleeve and forms driving connection with the driving wheel, and is driven to move in a reciprocating way between the lifting platform and the inner wall of the wellhole by the driving wheel; and the elastic element is arranged at the connecting end of the movable part. The invention further discloses lifting platform equipment comprising the lifting platform anti-dropping device. Compared with the prior art, the organic combination of the driving wheel, the movable part, the sleeve and the elastic element is effectively utilized, so that the lifting platform can be effectively supported in dropping, and therefore, safety accidents caused by dropping of the lifting platform can be effectively avoided.
Description
technical field [0001] The invention relates to a lifting platform in the field of elevators, in particular to an anti-falling device for the lifting platform and lifting platform equipment including the same. Background technique [0002] The lifting platform is a device that uses a drive unit to drive a transmission wheel, and the transmission wheel drives the platform up and down through a chain, a wire rope, etc. figure 1 Shown is a lifting platform device driven by a hydraulic cylinder. The lifting platform 1 is arranged in the shaft 2. The hydraulic cylinder 3 drives the transmission wheel 4 to rotate, and the transmission wheel 4 drives the lifting platform 1 to lift in the shaft 2 through the chain 41. [0003] When the above-mentioned lifting platform is in use, due to the influence of factors such as lack of oil in the hydraulic cylinder, broken chains or wire ropes, aging or bursting of oil pipes, and unexpected midway stop of the platform, it is easy to cause the...
