An intelligent turning device for welding and processing the main girder of bridge crane

Abstract

The invention discloses an intelligent overturning device for welding and processing main girders of bridge cranes, which includes an overturning support frame, an overturning frame, a smoke absorbing cover, a transposition roller, an adjustment sliding frame and a smoking connection pipe. The interior of the transposition cylinder is Hollow structure, the inside of the transposition drum is equipped with an inner partition, which divides the inner cavity of the transposition drum into smoking room I and smoking room II, and a three-way connecting pipe is set on the right side of the inside of the transposition drum, and the three-way connection The two inlets of the pipe are respectively connected with the smoking room I and the smoking room II, and the two inlet pipes of the three-way connecting pipe are equipped with solenoid valves; the structure design of the invention is novel, and the welding station and the installation and fixing station are separated to improve Production efficiency, realize the adjustment of turning, position and height, easy to operate, combine the smoke absorption mechanism with the turning structure, make the structure more compact, realize the automatic absorption of smoke in the welding process, and make the smoke treatment effect better.

Description

technical field [0001] The invention relates to the technical field of bridge crane processing and welding, in particular to an intelligent overturning device for welding and processing a main beam of an bridge crane. Background technique [0002] Overhead crane includes bridge frame and trolley frame. The bridge frame is composed of main beam, end beam, walking platform, guardrail and control room. The main beam mainly carries the sum of the weight of the trolley and the lifting object. Ribs, walking platforms and other accessories are welded. [0003] In the process of welding the main beam, the main beam needs to be turned over several times. Due to the large size and weight of the main beam, it needs to be turned over by the turning device. The existing turning device is complicated to operate. When the welding work is not carried out, the degree of automation is low, and once the main beam is fixed, the position cannot be adjusted, and the fixed height of the main beam...

Problems solved by technology

[0003] In the process of welding the main girder, it is necessary to turn over the main girder several times. Due to the large size and weight of the main girder, it is necessary to rely on the flipping device for flipping. The existing flipping device is cumbersome to operate. When the welding work is impossible, the degree of automation is low, and once the main girder is fixed, the position cannot be adjusted, and the fixed height of the main girder cannot be adjusted, so it is difficult to meet the needs of intelligence. The Chinese patent application No. A rotary frame welding overturning device, through the symmetrical overturning device, the rotary frame on the U-shaped beam can be turned over, and the height position can also be adjusted through the lifting device. Due to the design of the rotating device on the U-shaped beam frame, it can be rotated along the vertical plane. Perform 360-degree rotation; however, a large amount of fume will be generated during welding, and these fumes need to be equipped with a separate fume treatment device, which increases the investment in equipment, and the fume treatment device will always be in working condition, resulting in unnecessary resources Waste, welding work and workpiece fixing work cannot be carried out at the same time, and flow operation cannot be realized, resulting in low welding efficiency and unable to meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems
