Series connection structure type light vertical lifting platform

Abstract

A series connection structure type light vertical lifting platform comprises a car frame, a supporting mechanism, a bracket movement chain and a worktable. The light vertical lifting platform is a controllable planar mechanism with the multiple movable degrees; computer programming control is conducted by a servo motor system mounted on a chassis and servo electric cylinders mounted on the supporting mechanism and the bracket movement chain, so that the automation degree and the intellectualization degree are high; moreover, components of the supporting mechanism and the bracket movement chain are connected through rotating pairs, and the structure of the bracket movement chain is variable, so that reliability, maintainability and scalability are greatly improved; and compared with a vertical lifting platform driven by a hydraulic cylinder, the mechanical efficiency is effectively improved, and energy consumption is reduced. The series connection structure type light vertical lifting platform is simple in structure; through numerical control programming, high precision vertical lifting of the worktable can be realized, and short distance translation can be realized; and the series connection structure type light vertical lifting platform is especially suitable for the occasions such as digital workshops and intelligent logistics storehouses taking vertical conveyance light cargos and personnel as the principal thing and horizontal short distance movement as the subsidiary thing.

Description

technical field [0001] The invention relates to the field of vertical lifting platforms, in particular to a light-duty vertical lifting platform of series structure. Background technique [0002] Lifting platform is a kind of lifting equipment widely used in factories, automated warehouses, workshops, etc., for vertical transportation of people or goods. Effectively solve various lifting operation problems in industrial enterprises. Because the lifting platform is generally driven by hydraulic pressure, it is also called hydraulic lifting platform. Although the hydraulic lifting platform has been widely used, there are still many problems in the process of use. First, the hydraulic lifting platform has poor reliability and high maintenance costs. , and has high requirements for maintenance technology, if the maintenance is not thorough, the hydraulic oil is prone to be contaminated, the oil is prone to overheating during the working process, the oil seal is damaged and the...

AI Technical Summary

Problems solved by technology

Although the hydraulic lifting platform has been widely used, there are still many problems in the process of use. First, the reliability of the hydraulic lifting platform is poor, the maintenance cost is high, and the hydraulic components in the hydraulic system have high precision, which not only requires high maintenance , but also requires high maintenance technology, if the maintenance is not thorough, the hydraulic oil is prone to be contaminated, the oil is prone to overheating during the work process, the oil seal is damaged, and the air is easily mixed in, and the connection between the hydraulic cylinder and the pipeline is easy to loosen, and the oil leakage occurs. It increases the maintenance cost and affects the work efficiency; secondly, most of the existing lifting tables use conventional motors as power and are controlled by simple circuits, which have problems such as low intelligence and poor conveying accuracy of the workbench, making it difficult to adapt to modern The digital production line requires high precision and high flexibility for vertical lifting equipment; thirdly, the hydraulic system of the existing lifting table has high energy consumption and low mechanical efficiency, which is not conducive to the increasingly stringent environmental protection requirements. At the same time, the hydraulic system is affected by the hydraulic oil temperature. , leading to problems such as poor response speed of the workbench during manipulation, sluggish transmission, and oil return valve being stuck. Finally, existing lifting platforms, especially scissor lifting platforms, mainly perform vertical lifting operations. Due to structural design problems, it is difficult to realize Horizontal short-distance movement, poor flexibility
