Sleeper truss stirrup molding device

Abstract

The invention discloses a sleeper truss stirrup molding device, which comprises a frame-type bracket, wherein X axial guide rails are respectively arranged on support beams on two sides of the frame-type bracket, X axial guide rail grooves which move along an axial direction of the X axial guide rails are matched and installed on the X axial guide rails, a sliding frame is transversely connected between the guide rail grooves on two sides, and an X axial drive device for driving the sliding frame is installed on one side of the sliding frame; bridging beams on the two sides of the sliding frame are provided with axial guide rails, Y axial guide rail grooves which move along the axial direction of the Y axial guide rails are matched on the Y axial guide rails, translation support plates arearranged on the Y axial guide rail grooves, and Y axial drive devices are arranged on the translation support plates; the translation support plates are provided with Z axial drive devices, and the output ends of the Z axial drive devices are connected with a truss gripper assembly. According to the invention, through precise control of the X, Y and Z axes, the operation is efficient and accurate, and the device has the advantages of high consistency and strong universality; the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sleeper production, in particular, the invention relates to a sleeper truss stirrup molding device applied to a high-speed railway sleeper truss production line. Background technique [0002] Double-block sleeper is an important structural part embedded in the ballastless track concrete track bed slab to fix fasteners, rails and transmit train loads. Its high-precision manufacturing requirements can ensure the accuracy of the gauge during track laying. In order to ensure the strength of the sleeper, truss reinforcement is provided inside the sleeper, and the stirrups in the truss are welded with steel bars. When producing welded stirrups for steel bars, the coiled steel bars are first straightened by a straightening machine, then cut into individual steel bars according to the required length, then bent into stirrups by a semi-automatic stirrup forming machine, and finally made by manual welding The st...

AI Technical Summary

Problems solved by technology

Since the truss stirrup is composed of steel bars and its own weight is relatively heavy, a truss stirrup needs two workers to lift it up at the same time and put it into the corresponding position of the sleeper mold, and perform alignment and compression work, which is not only labor-intensive , and the work efficiency is very low
