Description

Technical Field

[0001] This utility model belongs to the field of railway sleeper reinforcement binding technology, specifically relating to a concrete railway sleeper reinforcement positioning and binding device. Background Technology

[0002] Concrete sleepers are a type of railway component. They must support the rails, maintain their position, and transfer the immense pressure from the rails to the track bed. They must possess a certain degree of flexibility and elasticity. When a train passes, they can deform appropriately to cushion the pressure, and after the train has passed, they must return to their original shape as much as possible.

[0003] In the production of railway sleepers, steel bars are used to reinforce the sleepers. Therefore, the correct positioning and binding of the steel bars are crucial. However, in the current traditional method of positioning and binding steel bars, workers usually hold and bind the steel bars manually. During binding, the steel bars are usually fixed with wire, and then the wire is manually twisted to bind the steel bars together. In this process, it is difficult to ensure that the steel bars will not shift during binding, which may lead to an unreasonable steel bar layout and a decrease in the overall quality of the finished sleeper. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete sleeper reinforcement positioning and binding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete sleeper reinforcement positioning and binding device includes: a base plate, wherein a positioning mechanism is provided on the top of the base plate;

[0007] The positioning mechanism includes two positioning frames. Each positioning frame has placement holes on both sides and multiple support grooves on its top. An installation groove is formed on one side of the inner wall of each support groove. A movable frame is slidably installed inside the installation groove. A threaded rod is threadedly connected to the inside of the movable frame. A drive cavity is formed inside the positioning frame. The bottom end of the threaded rod extends into the drive cavity. A synchronous pulley is fixed to the bottom end of the threaded rod, and a synchronous belt meshes between the synchronous pulleys. A positioning arc plate is fixed to one side of the movable frame. A servo motor is fixed inside the drive cavity, and its output end is fixedly connected to the bottom end of the threaded rod. Fixing grooves are formed on both sides of the inner wall of each placement hole. Multiple springs are fixed inside the fixing grooves, and positioning stops are fixed to the top of each spring.

[0008] Preferably, a guide groove is provided on one side of the inner wall of the support groove, and a guide frame is slidably installed inside the guide groove. One side of the guide frame is fixedly connected to the outer wall of the positioning arc plate.

[0009] Preferably, a stabilizing arc plate is fixed to the inner wall of the positioning arc plate, and the stabilizing arc plate is made of rubber.

[0010] Preferably, the top of the base plate is provided with an adjustment groove, a drive motor is fixed to one side of the base plate, a bidirectional lead screw is fixed to the output end of the drive motor, and two adjustment blocks are threaded to the outer wall of the bidirectional lead screw. The top of the adjustment blocks is fixedly connected to the bottom of the positioning frame.

[0011] Preferably, the top of the base plate has two limiting grooves, and two limiting blocks are slidably installed inside the limiting grooves. The top of the limiting blocks is fixedly connected to the bottom of the positioning frame.

[0012] Preferably, the top of the base plate has multiple mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The positioning arc plate in the positioning mechanism presses down vertically to clamp and position the reinforcing bar in a ring-like manner. Then, the spring drives the positioning stop block to block the reinforcing bar in the other direction. This helps to maintain the stability of the reinforcing bar during binding, avoids the position of the reinforcing bar from shifting during binding, and thus helps to bind it more firmly, thereby helping to improve the quality of the sleeper after it is formed.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, a concrete sleeper rebar positioning and binding device includes: a base plate 1, and a positioning mechanism is provided on the top of the base plate 1;

[0024] The positioning mechanism includes two positioning frames 2. Each positioning frame 2 has a placement hole 21 on both sides. Multiple support grooves 22 are formed on the top of each positioning frame 2. An installation groove 23 is formed on one side of the inner wall of each support groove 22. A movable frame 24 is slidably installed inside the installation groove 23. A threaded rod 25 is threadedly connected inside the movable frame 24. A protective cover is provided on the outer wall of the threaded rod 25 (this is existing technology and will not be described in detail here). A driving cavity 26 is formed inside the positioning frame 2. The bottom end of the threaded rod 25 extends into the driving cavity 26. A synchronous pulley 27 is fixed to the bottom of the 5, and a synchronous belt 28 meshes between the synchronous pulleys 27. The synchronous pulleys 27 and the synchronous belt 28 are existing technologies and will not be described in detail here. A positioning arc plate 29 is fixed to one side of the moving frame 24. A servo motor 210 is fixed inside the drive cavity 26. The output end of the servo motor 210 is fixedly connected to the bottom end of the threaded rod 25. Fixing grooves 211 are respectively opened on both sides of the inner wall of the placement hole 21. Multiple springs 212 are fixed inside the fixing grooves 211. A positioning stop block 213 is fixed to the top of the springs 212.

[0025] As can be seen from the above, when it is necessary to tie the reinforcing bars, the reinforcing bars are first placed into the placement hole 21 and the support groove 22 respectively. Then, by turning on the servo motor 210 in the positioning mechanism, the output end of the servo motor 210 rotates one of the synchronous pulleys 27. At this time, with the help of the synchronous belt 28, all the synchronous pulleys 27 can rotate, which in turn can rotate all the threaded rods 25. Therefore, the moving frame 24 can be driven to move in the mounting groove 23, which in turn drives the positioning arc plate 29 to press down vertically and hug the reinforcing bars. The steel bar is clamped and positioned, and then the spring 212 drives the positioning block 213 to block the steel bar in the other direction, which helps to maintain the stability of the steel bar during binding and avoids the steel bar position from shifting during binding, thus helping to bind it more firmly and thus helping to improve the quality of the sleeper after it is formed. After binding, by holding the steel bar, the positioning arc plate 29 moves upward and the positioning frame 2 moves to both sides. At this time, the steel bar squeezes the positioning block 213, so the spring 212 contracts, thus enabling the disassembly of the bound steel bar.

[0026] Specifically, regarding the above, please refer to... Figure 2 As shown, a guide groove 3 is provided on one side of the inner wall of the support groove 22, and a guide frame 4 is slidably installed inside the guide groove 3. One side of the guide frame 4 is fixedly connected to the outer wall of the positioning arc plate 29. A stabilizing arc plate 5 is fixed on the inner wall of the positioning arc plate 29. The stabilizing arc plate 5 is made of rubber.

[0027] As can be seen from the above, the cooperation between the guide groove 3 and the guide frame 4 provides precise guidance for the movement of the positioning arc plate 29, preventing it from shaking or shifting during the lifting process and ensuring the accuracy of the rebar positioning; the stabilizing arc plate 5 can increase the friction force, further enhance the fixing effect on the rebar, reduce the risk of rebar displacement during the binding process, thereby improving the forming quality and production efficiency of the sleeper rebar skeleton.

[0028] Example 2:

[0029] refer to Figures 1-4 As shown, the top of the base plate 1 is provided with an adjustment groove 6, and a drive motor 7 is fixed on one side of the base plate 1. A bidirectional lead screw 8 is fixed to the output end of the drive motor 7. Two adjustment blocks 9 are threadedly connected to the outer wall of the bidirectional lead screw 8. The top of the adjustment blocks 9 is fixedly connected to the bottom of the positioning frame 2. Two limiting grooves 10 are provided on the top of the base plate 1. Two limiting blocks 11 are slidably installed inside the limiting grooves 10. The top of the limiting blocks 11 is fixedly connected to the bottom of the positioning frame 2. Multiple mounting holes 12 are provided on the top of the base plate 1.

[0030] As can be seen from the above, the output of the drive motor 7 rotates, driving the bidirectional lead screw 8 to rotate, which in turn drives the adjusting block 9 to move. When positioning and binding, the adjusting blocks 9 move closer together, causing the positioning frame 2 to move closer together. When the binding is removed, the adjusting blocks 9 move further apart, causing the positioning frame 2 to move further apart. Therefore, the binding of the steel bars can be easily removed. The sliding of the limiting block 11 in the limiting groove 10 prevents the positioning frame 2 from shifting or shaking during the adjustment process, ensuring its smooth sliding and improving the adjustment accuracy. The setting of the mounting hole 12 facilitates the stable connection between the base plate 1 and external equipment and the workbench, enhances the overall structural rigidity, and avoids the impact of vibration caused by equipment operation on the positioning effect of the steel bars, laying a solid foundation for the production of high-quality sleepers.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
