Description

Technical Field

[0001] This utility model relates to the technical field of crane processing equipment, specifically to a hydraulic welding integrated machine for crane steel beam structures. Background Technology

[0002] When the existing main beam is too high, the web plate is too tall to stand upright, making assembly difficult. Generally, the web plate is placed on a platform, and the positioning lines for the longitudinal angle steel, eccentric steel, and main beam transverse diaphragms are first drawn on the web plate. The longitudinal angle steel and eccentric steel are then welded along the lines. Then, the positioning and positioning tack welds are performed on the main beam transverse diaphragms. The upper and lower cover plates of the main beam are then assembled and welded. After assembly, all welds are started inside the box girder. In order to make the main beam web plate and the main beam transverse diaphragms fit tightly, traditionally, the web plate's own weight and heavy weights, sledgehammers, manual chain hoists, jacks, pry bars, and other heavy and cumbersome tools are used. The disadvantages are high labor intensity and low production efficiency.

[0003] To address the aforementioned issues, publication number CN200920297015.3 discloses a hydraulic welding device for a box-type beam of a double gantry crane, comprising a gantry frame, a traveling end beam, a hydraulic pump platform placed on the gantry frame crossbeam, a hydraulic cylinder support mounted on the gantry frame crossbeam with a corresponding top hydraulic cylinder mounted on the support, a side hydraulic cylinder support mounted on the gantry frame column with a corresponding horizontal hydraulic cylinder mounted on the support, a pressure rod mechanism mounted on the telescopic wall of the hydraulic cylinder, two gantry frame columns respectively welded to the traveling end beam, a drive unit traveling wheel mounted on the traveling end beam, and a motor and reducer mounted on the traveling end beam. However, the hydraulic welding device for box girder of the double gantry crane still has the following problems: the crossbeam specifications and dimensions of the existing hydraulic welding device are mostly fixed, as are the columns and traveling end beams. It can only be used for processing steel beam structures within the specified specification range. It cannot automatically and quickly adjust the overall size of the hydraulic welding device according to processing requirements, resulting in low applicability. Furthermore, when the hydraulic cylinder fails, since there is no spare hydraulic cylinder, the machine needs to be stopped for maintenance and replacement before it can be used normally, which affects the efficiency of subsequent welding.
