Four-wheel synchronous rail change welding material transfer trolley

Abstract

The invention discloses a four-wheel synchronous rail change welding material transfer trolley. The trolley mainly comprises a trolley body, a workpiece lifting mechanism, a trolley body lifting mechanism, reversing mechanisms, advancing mechanisms, rails and a sliding electrifier; the workpiece lifting mechanism is mounted at the upper part of the trolley body; the trolley body lifting mechanism is mounted in a frame of a square steel pipe welding structure of the trolley body; the advancing mechanisms are mounted at four corners of the trolley body, and are connected with the reversing mechanisms; rails comprise longitudinal and transverse rails vertically intersected; the workpiece lifting mechanism can meet the requirements of lifting workpieces in different stations; when the transfer trolley is steered, the trolley body lifting mechanism lifts up the transfer trolley body, and the reversing mechanisms drive the advancing mechanisms to turn by 90 degrees; then, the trolley body lifting mechanism downwards move; and after the transfer trolley is descended, wheels are contacted with the rails to realize conversion of longitudinal and transverse directions of the transfer trolley. Compared with the prior art, the trolley is simple in overall structure, firm and fast in rail change mode, totally lifted, high in loading tonnage and stable in operation, and can greatly improve the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of logistics storage equipment, and in particular relates to a four-wheel synchronous track-changing welding material transfer vehicle. Background technique [0002] The rail transfer vehicle is a transport trolley that runs along the track. It is reliable in operation and relatively low in production cost. It is a commonly used handling equipment. In today's upgrading of multi-station welding production lines, compared with cranes or mobile cranes, transfer vehicles operate on the ground, and their operation reliability and automation are higher, and they can operate with multiple vehicles on track. Development and application gradually expanded. At present, the rail-changing transfer vehicles on the market often use eccentric wheel mechanisms, multi-link rocker mechanisms, and connecting-rod slider mechanisms to control the vertical and horizontal travel wheels to move up and down to achieve rail switchin...

AI Technical Summary

Problems solved by technology

At present, the rail-changing transfer vehicles on the market often use eccentric wheel mechanisms, multi-link rocker mechanisms, and connecting-rod slider mechanisms to control the vertical and horizontal travel wheels to move up and down to achieve rail switching and direction change. In addition, there are also rail switching station settings Large-scale turntable or the form of setting up sub-cars, usually this kind of track change method has a complicated structure and limited carrying capacity. When multiple vehicles run at the same time, there are requirements for track layout, and often need to carry batteries. The production cost is relatively high, so it is not suitable for Application in multi-station welding production line
