Description
Technical Field
[0001] This invention belongs to the field of railway sleeper prefabrication technology, specifically an automatic installation and disassembly device for steel bar pressing plates. Background Technology
[0002] With the development of high-speed railway technology, various new types of ballastless tracks, which replace ballast track beds with concrete or asphalt mixtures, aim to improve track stability and smoothness, and significantly reduce maintenance workload. Ballastless tracks have been widely laid and applied on newly built high-speed railway trunk lines, achieving excellent technical and economic results.
[0003] Currently, the most commonly used type of precast concrete sleeper is the double-block type. In the production of these sleepers, multi-sleeper casting molds can improve production efficiency. To ensure the structural strength of the sleepers, steel trusses are pre-placed within each sleeper precast shell in the mold. Steel reinforcement plates are then used to further fix the position of the reinforcement. These plates have flat heads, which are used to screw the pressure plate onto the steel reinforcement. The large number of plates and the complex steel trusses make the operation difficult. Furthermore, the installation and removal of the plates are two separate processes that need to be addressed before and after the sleeper prefabrication process. However, the existing method of pressing the reinforcement is manual, labor-intensive, inefficient, and not conducive to automated large-scale production. Summary of the Invention

Each V-shaped wrench 404 corresponds one-to-one with the flat head of the pressure plate 11 on the mold.
[0029] Implement a working method:
[0030] like Figure 1-4 , Figure 7As shown, the mold is located under the frame. The lifting cylinder extends and retracts to drive the crossbeam 1 to descend. Each V-shaped wrench 404 corresponds one-to-one with the flat head of the pressure plate 11 on the mold. The rod ends of the two lifting cylinders 604 extend downwards synchronously, with the T-shaped round heads flush with the height of the fracture groove 10. The two translation cylinders 606 extend and retract to drive the slide table 603 to translate along the slide rail 602, so that the T-shaped round heads of the lifting cylinders 604 enter the fracture groove 10. The rod ends of the two lifting cylinders 604 retract upwards synchronously, lifting the lifting beam 9 to rise. The pressure plate 11 rises past the highest point of the reinforcing bar, and several flat heads of the pressure plate 11 are inserted into the corresponding V-shaped wrench 404. The V-groove, in order to compensate for the height and position deviations caused by multiple point connections, can be passively compressed and eliminated by the spring 403 set in the V-wrench 404. The rotary drive cylinder 2 extends and retracts to drive the swing shaft V-wrench 4 connected by several connecting rods 3 to swing and rotate, so that the swing shaft 401 rotates around the axis. The V-wrench 404 rotates and outputs torque, so that the flat heads of several corresponding pressure plates 11 rotate, for example, by 90 degrees. The pressure plates 11 rotate accordingly and have a pressing or disassembly position. The rod end of the lifting cylinder 604 extends downward synchronously, lifting the lifting beam 9 to descend, releasing the pressure plates 11 to press or disassemble the steel bars.
[0031] Implementation of the second working method:
[0032] like Figure 1-2 , Figure 5-7 As shown, the inverted mold is located above the machine frame, with the pressure plate 11 inside the mold facing downwards. The push cylinder 23 extends and retracts, driving the moving seat 18 to move along the large slide rail 19 to below the mold. Each V-shaped wrench 404 corresponds one-to-one with the flat head of the pressure plate 11 in the mold. The rod ends of the two lifting cylinders 604 extend upwards synchronously, with the T-shaped round heads flush with the height of the fracture groove 10. The two translation cylinders 606 extend and retract, driving the slide table 603 to translate along the slide rail 602, causing the T-shaped round heads of the lifting cylinders 604 to enter the fracture groove 10. The rod ends of the two lifting cylinders 604 retract downwards synchronously, causing the lifting beam 9 to descend. The pressure plate 11 descends past the highest point of the reinforcing bar, and several flat heads of the pressure plate 11 are inserted into the corresponding V-shaped wrench 404. The V-groove, in order to compensate for the height and position deviations caused by multiple point connections, can be passively compressed and eliminated by the spring 403 set in the V-wrench 404. The rotary drive cylinder 2 extends and retracts to drive the swing shaft V-wrench 4 connected by several connecting rods 3 to swing and rotate, so that the swing shaft 401 rotates around the axis. The V-wrench 404 rotates and outputs torque, so that the flat heads of several corresponding pressure plates 11 rotate, for example, by 90 degrees. The pressure plates 11 rotate accordingly and have a pressing or disassembly position. The rod end of the lifting cylinder 604 extends upward synchronously, lifting the lifting beam 9 to rise, and releasing the pressure plates 11 to press or disassemble the steel bars.
