Lifting platform

Abstract

The invention discloses a lifting platform, comprising a supporting frame, a transmission mechanism, a sliding mechanism and a lifting bracket. The transmission mechanism comprises a first transmission assembly, a second transmission assembly, a fixed seat and a transmission shaft, wherein the fixed seat is arranged on the supporting frame, and the transmission shaft penetrates through the fixed seat and the two ends of the transmission shaft are respectively and fixedly connected with the first and second transmission assemblies; the first transmission assembly comprises a handle, a worm and a worm wheel, wherein the handle penetrates through the supporting frame and is pivoted with the supporting frame, the worm is fixedly connected with one end of the handle, and the worm wheel is fixedly connected with one end of the transmission shaft and is engaged with the worm; the second transmission assembly comprises a rack and a gear, wherein the rack is vertically arranged on the lifting bracket, and the gear is fixedly connected with the other end of the transmission shaft and is engaged with the rack; and the sliding mechanism comprises a guide rail and a sliding block, wherein the guide rail is arranged on the supporting frame and is parallel with the rack, and the sliding block is arranged on the lifting bracket and is clamped with the guide rail in a sliding manner. The lifting platform has the advantages of steady, safe and reliable lifting, high lifting precision, large stroke, no noise when in use, no pollution of environment, simple structure and compactness.

Description

technical field [0001] The invention relates to a handling device, in particular to a lifting platform. Background technique [0002] In home life or shopping mall sales display, it is often necessary to carry some items, such as home appliances, furniture, cabinets, vases, etc. Usually, people use manual lifting to carry items. However, manual handling is not only laborious, but sometimes requires many people. Assistance can be completed, therefore, people wish to have a lifting platform that can load items to replace manual handling. [0003] 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. Traditional lifting platforms are mostly used in industry, construction, transportation, high-altitude operations, etc. They are generally large in size and have complex and heavy structures, so they are ...

AI Technical Summary

Problems solved by technology

Traditional lifting platforms are mostly used in industry, construction, transportation, high-altitude operations, etc. They are generally large in size and have complex and heavy structures, so they are not suitable for general household life or shopping malls; in addition, most traditional lifting platform mechanisms use hydraulic lifting System to drive, because the hydraulic lifting system requires hydraulic cylinders and liquid pumps, so this kind of lifting platform mechanism is only suitable for industry, and it will cause noise and pollution when used indoors
