Synchronous driving multipoint suspension vertical lifting platform

Abstract

The invention relates to a synchronous driving multipoint suspension vertical lifting platform for solving the driving synchronization problem of the multipoint suspension vertical lifting platform. The synchronous driving multipoint suspension vertical lifting platform comprises a lifting platform main body, a power device, rollers and steel wire ropes. After the synchronous driving multipoint suspension vertical lifting platform is improved, each roller is wound with two steel wire ropes the directions of which are opposite. One end of each steel wire rope is respectively connected with therollers. The other end of one steel wire rope is fixedly connected with one suspension point of the lifting platform main body by a steel wire rope buffering slack adjuster, while the other end of the other steel wire rope passes through a fixed pulley above the lifting platform to be fixedly connected with the same suspension point of the lifting platform main body by a steel wire rope buffer and a steel wire rope slack adjuster. More than two suspension points are uniformly distributed on the lifting platform main body. The invention avoids the problems of unstable operation, large noise and difficult synchronization adjustment of the chain multipoint synchronous driving mode, eliminates the adverse effect of the problem of easy slipping of the common steel wire rope driving mode on themultipoint synchronous driving and can meet the requirements of the large-span lifting platform for the stable operation.

Description

technical field [0001] The invention relates to a mechanical lifting device, in particular to a synchronously driven multi-point suspension vertical lifting platform, which belongs to the technical field of transportation. Background technique [0002] Vertical lift platforms are widely used in mechanical three-dimensional parking garages and other lifting machinery. For smaller lift platforms, single-point suspension drive mode is generally used. Typical application examples are elevators. Because it is a single-point drive, there is no synchronization problem, so the wire rope suspension drive method is generally used. For a lifting platform with a relatively large horizontal distribution area, such as the vertical lifting platform of a barrel-type mechanical three-dimensional parking garage, the span of the lifting platform reaches more than 10 meters, and the vehicle has to move horizontally on the platform during the process of accessing the car, resulting in a large de...

Problems solved by technology

Although the chain drive can eliminate slippage and ensure the realization of synchronous drive, the polygonal effect of the chain drive makes the entire drive system run smoothly and increase noise. At the same time, because the chain has a fixed pitch, it is very difficult to adjust the drive system synchronously. When there are more than 3 driving points, it is almost impossible to adjust the drive system to the ideal synchronous state, the result is that the drive system wears faster and the transmission efficiency drops significantly

Under normal circumstances, the chain and the sprocket can maintain a synchronous meshing state. When serious out-of-synchronization occurs, tooth jumping may occur between the sprocket and the chain, making the out-of-synchronization phenomenon more serious.
