Automatic lifting platform capable of quickly running and locating with high precision, and elevator

Abstract

The invention discloses an automatic lifting platform capable of quickly running and locating with high precision, and an elevator. The automatic lifting platform comprises a supporting frame, a lifting moving platform arranged in the supporting frame, and a lifting driving mechanism which drives the lifting moving platform to make lifting motion, wherein guide rails are arranged on the supportingframe; rail wheels matched with the guide rails are arranged on the two sides of the lifting moving platform; the lifting moving platform moves up and down on the lifting moving platform; the liftingmoving platform comprises an operation vehicle and operation vehicle rails; rollers matched with the operation vehicle rails are arranged on the operation vehicle; the operation vehicle moving left and right on the operation vehicle rails; and a plurality of position clamping assemblies are arranged at the bottom of the lifting moving platform and used for performing position clamping on the lifting of the lifting moving platform so as to adjust the stop height of the lifting moving platform. On the premise of not resorting to a complicated control system and a control method, rapid running of the automatic lifting platform is realized by personal mechanical and structural features of the automatic lifting platform. The automatic lifting platform has the multiple advantages of stability in running, high velocity and precision in location.

Description

technical field [0001] The invention belongs to the technical field of lifting equipment. More specifically, it relates to a fast-moving and high-precision positioning automatic lifting platform and elevator. Background technique [0002] The lifting platform is a multi-functional lifting and unloading mechanical equipment, which can generally be divided into: fixed lifting platform, mobile lifting platform, guide rail lifting platform and crank arm lifting platform. Lifting platform can be used in industry, construction, transportation, aerial work and other fields. [0003] The existing lifting mobile platform basically adopts the elevator-type scheme, the design is complex and the running speed is slow, and sensors are usually used for positioning, the positioning accuracy is low, and serious phenomena such as track misalignment often occur. Once the track misalignment occurs, when the working vehicle passes by It will be unstable, even flipping and falling, which is ex...

[0003] The existing lifting mobile platform basically adopts the elevator-type scheme, the design is complex and the running speed is slow, and sensors are usually used for positioning, the positioning accuracy is low, and serious phenomena such as track misalignment often occur. Once the track misalignment occurs, when the working vehicle passes by It will be unstable, even flipping and falling, which is extremely dangerous. Once an accident occurs, it will have unimaginable consequences; some lifting mobile platforms use hydraulic pressure as power to pull the lifting mobile platform up and down through the chain Among them, there are many unstable factors in the hydraulic lifting system, which is not conducive to long-term maintenance and maintenance. The design and installation are relatively complicated. A deep foundation pit needs to be dug on site, and there are many layers of poles, which makes maintenance more troublesome; some lifting platforms use the worm and worm gear to rotate together, and the rack and gear to realize the lifting of the lifting platform. In the process of lifting, it is prone to jitter and the stability is not high
