Hydraulic turnover tool for large rod piece

Abstract

The invention relates to a hydraulic turnover tool for a large rod piece. The hydraulic turnover tool comprises a base, a support, an oil cylinder and an L-shaped bracket, wherein the support is vertically welded to the base, and the oil cylinder and the L-shaped bracket are arranged at the two ends of the support respectively. The upper end of the L-shaped bracket is hinged to the supporting seat, and the lower end of the L-shaped bracket is hinged to a piston rod of the oil cylinder. The L-shaped bracket is pushed by the piston rod of the oil cylinder to rotate around the hinge position. The hydraulic turnover tool has the advantages that the hydraulic turnover tool for the large rod piece provides lifting force through the oil cylinder, and the whole turnover work process is stable and safe; meanwhile, the turnover movement of the rod piece can be carried out from the midair to the ground through a turnover mechanism, the turnover tool can be suitable for turnover of rod pieces of different types, the influence of rod piece structure modes is small, and the mechanization work degree of hoisting and turnover is improved; the L-shaped support is pushed to rotate by 90 degrees around a pin shaft within the limited stroke, turnover of the rod piece is achieved, and if the rod piece needs to be turned over by 180 degrees, the process can be operated by being divided into two 90-degree turnover movements.

Description

technical field [0001] The invention relates to a turning tool, in particular to a hydraulic turning tool for large rods. Background technique [0002] In the heavy industry machinery manufacturing industry, many kinds of large rods need to be produced. In the manufacturing process, in order to complete the steps of assembly, welding, grinding, hoisting, etc., the rods need to be turned over. The traditional method of turning over a bar is to use a wire rope, and two cranes cooperate with each other to turn the member from a horizontal state to a vertical state to perform the turning operation. Steel truss-type steel bridge members have a complex structure, and the length of the members may often be less than the minimum opening distance of two driving vehicles. Using the traditional method to turn over is time-consuming and laborious, the safety cannot be guaranteed, and it is easy to cause surface damage and deformation of the members. Therefore be badly in need of develo...
