With the development of industrialization, the application of hoisting machinery in industry is becoming more and more common, and the technology of hoisting machinery is becoming more and more popular,the tonnage of the crane is larger and larger, and the production requirements of the lifting machinery are higher and higher. In the production process of the crane, the crane beam needs to weld the left and right webs and cover plates together. In the welding process, in order to facilitate the welding operation, it is necessary to turn the webs and cover plates at a certain angle to facilitate the welding operation. However, there are many defects in the current form of turnover, The existing turnover device has different types of beams. When welding, the beam is easy to slide during the turnover process, resulting in the collision between the crane beam and the turnover device, which is easy to cause damage to the turnover device. In addition, during the turnover process, the crane beam is easy to slide and rub with the turnover device, resulting in damage. In addition, the turnover angle can not be overturned according to different types of crane beams, and can not be adjusted to the best angle for welding, Finally, after adjusting the angle, it is not easy for the crane beam to be fixed. Usually, the compaction method is easy to cause the unwelded side web to bear larger external forces, which is easy to cause the deformation of the crane beam.
The invention relates to a crane beam welding load turn device, which comprises a base, both ends of the base are hinged with a hydraulic cylinder a and a hydraulic cylinder B, the hydraulic cylinder a and the hydraulic cylinder B are hinged with a turnover frame a and a turnover frame B respectively, the upper surface of the horizontal support of the turnover frame a and the turnover frame B is provided with a rolling seat, the upper part of the vertical support of the turnover frame a is provided with a support plate a, the rear side of the support plate a is provided with an electromagnet a, and the middle of the turnover frame a is provided with a contact switch a, An electric push rod a is connected to the lower side of the turnover frame a, a rolling seat is arranged on the upper surface of the horizontal support of the turnover frame B, a rotating roller is arranged in the rolling seat, a support plate B is arranged on the upper part of the vertical support of the turnover frame B, an electromagnet B is arranged on the rear side of the support plate B, a contact switch B is arranged in the middle of the turnover frame B, and the lower side of the turnover frame B.
The invention has the advantages of simple structure, convenient use, convenient operation and reasonable design.
