Linkage type height adjusting device

Abstract

The invention provides a linkage type height adjusting device which comprises a machine frame, a height control panel and a chain plate. The height control panel is arranged on the end face of the machine frame and provided with a height control mechanism. A height adjusting shaft penetrates through the height control panel. The chain plate is arranged on the side face of one end of the machine frame. A first fixed clamping base and a second fixed clamping base are arranged on the back face of the chain plate. The height adjusting shaft penetrates into the first fixed clamping base. A drivingbevel gear is arranged on the height adjusting shaft. Three height holes are formed in the chain plate. Height blocks penetrate through the three height holes correspondingly. The linkage type heightadjusting device is small in occupied area and adjustable in height, can be matched with other automatic truss welding devices for welding trusses of different specifications, has applicability, greatly improves the truss production efficiency, and avoids the problems that when the trusses of different specifications are welded manually, operations are complicated, precision is not high and the space is occupied.

Description

technical field [0001] The invention relates to the technical field of elevator bases, in particular to a linkage height adjustment device. Background technique [0002] A truss is a structure composed of rods connected to each other with hinges at both ends, and is widely used in building structures such as houses and bridges. In the pipe truss structure, the material of the main straight rod is generally a seamless steel pipe. In order to meet the use requirements, this seamless steel pipe usually has a length of more than ten meters. It is difficult to process the pipe truss of this length, and the welding of the truss web is usually It is completed by manual welding, but the quality of manual welding fluctuates greatly, the efficiency is not high, and the accuracy is unstable; if it is necessary to produce trusses with different web specifications and sizes, seamless steel pipes need to be placed in different sizes for welding, and the operation is complicated at the sam...

Problems solved by technology

In the pipe truss structure, the material of the main straight rod is generally a seamless steel pipe. In order to meet the use requirements, this seamless steel pipe usually has a length of more than ten meters. It is difficult to process the pipe truss of this length, and the welding of the truss web is usually It is completed by manual welding, but the quality of manual welding fluctuates greatly, the efficiency is not high, and the accuracy is unstable; if it is necessary to produce trusses with different web specifications and sizes, seamless steel pipes need to be placed in different sizes for welding, and the operation is complicated at the same time. It greatly occupies the production space and affects the production efficiency of the enterprise; due to the length of the seamless steel pipe, it is difficult for the existing automatic truss welding device to adjust the height and position of the seamless steel pipe, so it is difficult to apply to the welding of pipe trusses of different specifications Production
