An elevator for heavy workpiece transportation

Abstract

The invention provides a lifting machine for conveying a heavy tool. The lifting machine is provided with a rack that is provided with four vertical columns, wherein the four vertical columns are arranged like a rectangle; a driving device I, which is connected with a transmission shaft through a drum gear coupling, is arranged at one end of the rack; four driving chain wheels on which chains are lapped are arranged on the transmission shaft; one end of each of the chains is fixedly connected with a balance weight below the chain; two driven chain wheels, which are corresponding to the two driving chain wheels at two ends of the transmission shaft, are arranged at the other end of the rack; the chains lapped on the driving chain wheels at two ends of the transmission shaft round the corresponding chain wheels and then are connected with a lifting frame arranged below; another chains lapped on the two driving chain wheels in the middle part of the transmission shaft directly downwards extend to connect with the lifting frame; a roller bed is fixedly connected to the lifting frame. According to the lifting machine for conveying the heavy tool, the lifting frame and the roller bed are connected through the rack that is provided with four vertical columns and the four chains, and thus, the heavy tool can be lifted; the lifting machine is high in carrying capacity and high in working efficiency.

Description

technical field [0001] The invention relates to a conveying device for transferring between different process plane routes of a production line, in particular to an elevator used in a skid conveying system in an automobile painting workshop. Background technique [0002] In recent years, with the rapid development of my country's economy, the automobile industry has also developed by leaps and bounds, especially the rapid development of my country's bus industry in recent years. my country's bus industry has quietly moved from the domestic market to the international market. The modern automobile painting workshop is developing from a flat layout to a three-dimensional layout. In the automotive coating conveying equipment, the function of the elevator is to transport the workpiece, body or skid from a low place to a high place, or from a high place to a low place. When the lifting equipment is working, it must be stable, reliable and accurate. The driving device is equippe...
