Description

Technical Field

[0001] The utility model relates to the technical field of turnover equipment, in particular to a turnover tool for large bridge support parts. Background Art

[0002] Bridges are key components in road traffic, and bridge bearings are key components in bridge construction. They adapt to the effective load, deformation, and rotation of the beam body and transmit the upper load to the pier foundation. The installation quality of the bearings will directly affect the operational safety of the bridge. The load, deformation, rotation of the beam body and the installation quality of the bearings are all crucial to bridge safety. At the same time, bridge bearings play a connecting role.

[0003] During the production process of bridge bearings, the bridge bearing components need to be processed and then assembled, and the components need to be turned over during processing, which requires the cooperation of turning equipment. Small bridge bearing components are light in weight, so they can be turned over by ordinary motor drive. However, for large bridge bearing components, because the large components are too heavy, turning them over using ordinary motor-driven turning machines requires the selection of large-sized, expensive, and complex turning equipment, which greatly increases the cost. Therefore, a turning equipment with a simple structure and low cost is needed. Utility Model Content
