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.

Embodiment Construction
[0037] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0038] In order to achieve the purpose of the present invention, as Figure 2-3 As shown, in some embodiments of the lifting platform fall prevention device of the present invention, it is applied to lifting platform equipment. In this embodiment, the lifting platform equipment includes a lifting platform 1, a hoistway 2, a hydraulic cylinder 3, and a transmission wheel 4 and chain 41, the lifting platform 1 is set in the hoistway 2, the hydraulic cylinder 3 drives the transmission wheel 4 to rotate, and the transmission wheel 4 drives the lifting platform 1 to go up and down in the hoistway 2 through the chain 41, and the transmission wheel 4 is generally used as a driving wheel. A driven wheel should also be installed in cooperation, and this structure can be known from the lifting platform equipment in the prior art, and will not be descri...

The invention discloses an anti-falling device for a lifting platform. The lifting platform is driven up and down in the hoistway by a drive unit and a transmission wheel. The anti-falling device for the lifting platform includes: a sleeve, which is fixedly installed on the lifting platform; It is installed in the sleeve, and the connecting end of the movable part in the sleeve forms a transmission connection with the transmission wheel, which is driven by the transmission wheel to move back and forth between the lifting platform and the inner wall of the hoistway; the elastic element is installed on the movable part connection end. At the same time, the invention also discloses a lifting platform equipment including the falling prevention device of the lifting platform. Compared with the prior art, the present invention effectively utilizes the organic combination of transmission wheels, movable parts, sleeves and elastic elements, so that the lifting platform can be effectively supported when it suddenly falls, thereby effectively avoiding the A safety accident caused by the platform falling.
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...
