Intelligent turnover device for welding and processing main beam of bridge crane

Abstract

The invention discloses a bridge crane main beam welding processing intelligent turnover device which comprises a turnover supporting frame, a turnover frame, a smoke absorption cover, a position changing roller, an adjusting sliding frame and a smoke absorption connecting pipe, the interior of the position changing roller is of a hollow structure, and an inner partition plate is arranged in the position changing roller; an inner cavity of the transposition roller is divided into a smoking chamber I and a smoking chamber II by the inner partition plate, a three-way connecting pipe is arranged on the right side of the interior of the transposition roller, two inlets of the three-way connecting pipe are communicated with the smoking chamber I and the smoking chamber II respectively, and electromagnetic valves are arranged on two inlet pipes of the three-way connecting pipe; the welding device is novel in structural design, a welding station and a mounting and fixing station are separated, the production efficiency is improved, overturning and position and height adjustment are achieved, operation is convenient, a flue gas absorption mechanism and an overturning structure are combined together, the structure is more compact, automatic absorption of flue gas is achieved in the welding process, and the flue gas treatment effect is 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 bridge crane main girder welding and processing. Background technique [0002] The bridge crane includes a bridge frame and a trolley frame. The bridge frame is composed of a main girder, an end girder, a walking platform, a guardrail and a control room. Ribs, walkways and other accessories are welded. [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 in...

[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
