[0002] With the booming development of the construction industry, prefabricated buildings have come into people's view, and prefabricated component factories have gradually developed. In the prior art, when limiting the protruding reinforcement, it is necessary to make the reinforcement contact with the limiting plate. Since the staff cannot be reminded when the limiting plate contacts the reinforcement, the reinforcement will continue to move after contact, resulting in wear at the end of the reinforcement and inability to protect the reinforcement.

[0003] For example, the patent application number is CN202021644438.0. This utility model discloses a device for limiting the protruding length of a precast component. The structure of this utility model is reasonable. It adopts a scale structure with a sliding block, which can preset the protruding length and ensure the accuracy of the actual protruding length. It adopts a sliding magnetic plate structure to limit the reinforcement during protruding through magnetism, ensuring that there is no displacement during protruding. The device realizes convenient adjustment of the protruding length through manual adjustment, realizes the saving of electric energy and the best length adjustment of the protruding length, avoids waste of reinforcement and construction errors during concrete pouring caused by inconsistent protruding lengths. When in use, the staff cannot be reminded when the limiting plate contacts the reinforcement, so that the reinforcement will continue to move after contact, resulting in wear at the end of the reinforcement and inability to protect the reinforcement.

[0004] For example, the patent application number is CN202121194262.8. This utility model relates to the technical field of precast PC boards, and particularly relates to a structure for limiting the protruding reinforcement of a precast PC board. This utility model places the limiting thick reinforcement into the U-shaped groove of the limiting plate, and then binds the reinforcement to the limiting thick reinforcement. Due to the self-gravity of the limiting thick reinforcement and the resistance of the side of the U-shaped groove of the limiting plate, the floating of the reinforcement is restricted, preventing the deformed reinforcement from warping up and affecting the protective layer, so as to control the protective layer thickness to meet the requirements. The structure is simple and the cost is low. When in use, the staff cannot be reminded when the limiting plate contacts the reinforcement, so that the reinforcement will continue to move after contact, resulting in wear at the end of the reinforcement and inability to protect the reinforcement.

[0023] The moving mechanism 2 includes a moving plate 201. The moving plate 201 is located inside the groove 3 and is movably connected to the die table 1. A fixing plate 202 is provided at the top of the moving plate 201, and the number of the fixing plates 202 is multiple. A sliding block 203 is provided at the top of one end of the moving plate 201. The bottom end of the sliding block 203 is movably connected to the sliding groove 4. A buffer plate 204 is provided on one side of the moving plate 201. A connecting rod 205 is provided at the top of the buffer plate 204. One end of the connecting rod 205 is provided with a cross bar 206, and the cross bar 206 is fixedly connected to the connecting rod 205. A limiting rod 207 is provided at the top of the cross bar 206. The height of the limiting rod 207 is greater than the height of the fixing plate 202. An impact block 208 is provided at one end of the cross bar 206 away from the connecting rod 205.

[0024] A small bell 209 is provided at the top of the moving plate 201. The number of the small bells 209 is equal to the number of the impact blocks 208, and each small bell 209 is aligned with each impact block 208. The number of the impact blocks 208 and the small bells 209 is relatively large, so that the sound is relatively loud, which is convenient for reminding the staff that the limit work on the steel bar extraction has been completed.

[0025] A motor 210 is provided at the top of the die table 1. The end of the output shaft of the motor 210 is provided with a threaded rod 211. The threaded rod 211 passes through the sliding block 203 and is threadedly connected to the sliding block 203. By driving the motor 210, the threaded rod 211 rotates, so that the threaded rod 211 rotates on the sliding groove 4. When the threaded rod 211 rotates, because the threaded rod 211 is threadedly connected to the sliding block 203, the rotation of the threaded rod 211 causes the sliding block 203 to move. The bottom end of the sliding block 203 extends into the sliding groove 4 and is movably connected to the sliding groove 4, so that the sliding block 203 moves linearly along the sliding groove 4.

[0026] Two connecting springs 212 are provided between the buffer plate 204 and the moving plate 201, so that the buffer plate 204 moves and the connecting springs 212 are deformed to achieve a buffering effect.

[0027] A support plate 213 is provided at the top of the moving plate 201. The support plate 213 is fixedly connected to the small bell 209 through a rope. The impact block 208 can impact the small bell 209 without affecting the swaying of the small bell 209. The threaded rod 211 is located at the top of the sliding groove 4. The cross-sectional shape of the support plate 213 is L-shaped.

[0028] During operation, when the steel bar enters the groove 3 on the surface of the die table 1, the motor 210 is used first. Since the output shaft end of the motor 210 is connected to the threaded rod 211 by transmission, the threaded rod 211 is driven by the motor 210 to rotate, so that the threaded rod 211 rotates on the slide groove 4. When the threaded rod 211 rotates, because the threaded rod 211 is threadedly connected to the sliding block 203, the sliding block 203 moves through the rotation of the threaded rod 211, and the bottom end of the sliding block 203 extends to the inside of the slide groove 4, and The sliding block 203 is movably connected to the slide groove 4, so that the sliding block 203 moves linearly along the slide groove 4, and the fixed plate 202 fixedly connected to the sliding block 203 moves at the same time. When the fixed plate 202 moves, since the fixed plate 202 is fixedly connected to the moving plate 201, the moving plate 201 moves with the fixed plate 202, and pushes the buffer plate 204 to move, so that the buffer plate 204 and the moving plate 201 move in the groove 3 on the surface of the mold platform 1, so that the buffer plate 204 and the mold platform 1 move to the specified position. , the motor 210 is stopped, so that the buffer plate 204 and the die table 1 are fixed, which is convenient for subsequent operations. Later, when the steel bar is out, it will enter the groove 3 and contact with the buffer plate 204, and the buffer plate 204 is connected to the moving plate 201 through the connecting spring 212, so that the buffer plate 204 moves and the connecting spring 212 is deformed. The movement of the buffer plate 204 makes the connecting rod 205 above move at the same time, pushing the limiting part fixedly connected to the connecting rod 205 The rod 207 and the cross bar 206 move. When the cross bar 206 moves, the impact block 208 at one end of the cross bar 206 merges with the small bell 209 and produces a certain sound to remind the surrounding staff. When the limiting rod 207 moves, the limiting rod 207 can be brought into contact with the support plate 213 to prevent the limiting rod 207 from continuing to move, and the buffer plate 204 can be prevented from continuing to move, so as to prevent the buffer plate 204 from continuing to move due to the steel bars continuing to push the buffer plate 204 to move, thereby limiting the output of the steel bars.
