Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building steel reinforcement technology, and in particular relates to a support device for detecting steel reinforcement bending. Background Technology
[0002] The purpose of steel bar bending testing is to ensure that steel bars meet relevant engineering quality standards and design requirements when subjected to bending forces, to ensure the safety and stability of building structures during use, and to avoid problems such as cracks, deformation, or even structural damage due to poor steel bar bending performance.
[0003] When testing the bending of reinforcing bars, the reinforcing bars need to be placed on a support device, and then a force is applied to the reinforcing bars by a testing machine until the reinforcing bars reach a suitable bending angle. However, the pulleys on the support device are generally not equipped with protective structures. During the process of being stressed, the reinforcing bars may slip out of the pulley grooves. Therefore, we designed a support device for testing the bending of reinforcing bars to protect and limit the reinforcing bars, prevent slippage during the bending process, and ensure the safety of the testing environment. Utility Model Content
[0004] The purpose of this invention is to provide a support device for detecting the bending of reinforcing bars, which has the advantages of protecting and limiting the reinforcing bars, preventing slippage during the bending process, and ensuring a safe testing environment, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A support device for detecting the bending of reinforcing bars includes a support base. Two movable support members are provided on the top of the support base. A shaft pin is provided through the support member and is fixedly connected to the support member. A support pulley located in the inner cavity of the support member is rotatably connected to the surface of the shaft pin. A rotating plate located in front of the support member is sleeved on the surface of the shaft pin. A movable sleeve is sleeved on the surface of the rotating plate. A limiting plate located above the support pulley is fixedly connected to the top of one side of the sleeve. An adjustment assembly is provided between the two support members and the support base. A locking assembly is provided between the rotating plate and the sleeve. A fastening hoop sleeved on the surface of the shaft pin is fixedly connected to the front side of the rotating plate.
[0006] Preferably, a fastening screw is provided through the end of the fastening hoop.
[0007] Preferably, the adjustment assembly includes a bidirectional threaded rod rotatably connected to the inner cavity of the support base, with threaded sleeves threaded to both ends of the surface of the bidirectional threaded rod, and two symmetrical connecting blocks fixedly connected to the bottom of the support member, the bottoms of the two connecting blocks penetrating into the inner cavity of the support base and fixedly connected to the threaded sleeves.
[0008] Preferably, two sliding grooves for sliding of the connecting block are provided on both sides of the top of the support base, and the end of the bidirectional threaded rod extends through to the outside of the support base and is fixedly installed with a handwheel.
[0009] Preferably, the locking assembly includes a slot formed on the top of one side of the rotating plate, a locking pin slidably connected to the inner cavity of the slot, a spring welded between the locking pin and the inner wall of the slot, and a plurality of locking holes adapted to the locking pin are formed on one side of the housing.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model places the reinforcing bar in the grooves on two supporting pulleys, then presses down the limiting plate. The limiting plate drives the sleeve to slide on the surface of the rotating plate until the limiting plate is in contact with the surface of the reinforcing bar. The limiting plate is then locked by the locking component. During the bending process of the reinforcing bar, it will drive the supporting pulleys to rotate. The bent reinforcing bar will also drive the sleeve and the rotating plate to rotate around the axle pin through the limiting plate, thus preventing the reinforcing bar from slipping out of the grooves on the surface of the supporting pulleys. This achieves the purpose of protecting and limiting the reinforcing bar, preventing it from slipping during bending, and ensuring the safety of the testing environment.
[0012] 2. By adjusting the arrangement of the components, this utility model can adjust the distance between the two support pulleys, thereby improving the adaptability of the support device;
[0013] 3. This utility model uses the combination of fastening hoop and fastening screw. Tightening the fastening screw can tighten the fastening hoop, which can increase the friction of the rotating plate on the surface of the shaft pin, and prevent the rotating plate from rotating randomly on the surface of the shaft pin. During the bending of the steel bar, the rotating plate will be driven to rotate through the limiting plate and the sleeve, ensuring the stability of the limiting state. Attached Figure Description

Detailed Implementation
[0021] In the following description, embodiments of the support device for detecting the bending of reinforcing bars according to the present invention will be described with reference to the accompanying drawings.
[0022] Figure 1-4 This invention illustrates a support device for detecting the bending of reinforcing bars according to an embodiment of the present invention. It includes a support base 1, with two movable support members 2 on the top of the support base 1. A pin 3 is passed through each support member 2 and is fixedly connected to the pin 3. A support pulley 4 located within the cavity of the support member 2 is rotatably connected to the surface of the pin 3. A rotating plate 5 located in front of the support member 2 is fitted onto the surface of the pin 3. A movable sleeve 6 is fitted onto the surface of the rotating plate 5. A limiting plate 7 located above the support pulley 4 is fixedly connected to the top of one side of the sleeve 6. An adjustment assembly 8 is provided between the two support members 2 and the support base 1. The adjustment assembly 8 includes a bidirectional threaded rod 81 rotatably connected to the cavity of the support base 1. Threaded sleeves 82 are threaded to both ends of the surface of the bidirectional threaded rod 81. Two symmetrical connecting blocks 83 are fixedly connected to the bottom of the support members 2. The bottoms of the two connecting blocks 83 penetrate into the cavity of the support base 1 and are fixedly connected to the threaded sleeves 82. Two sliding grooves 8 are provided on both sides of the top of the support base 1 for the connecting blocks 83 to slide. 4. The end of the bidirectional threaded rod 81 extends to the outside of the support base 1 and is fixedly mounted with a handwheel 85. By adjusting the setting of the component 8, the distance between the two support pulleys 4 can be adjusted to improve the adaptability of the support device. A locking component 9 is provided between the rotating plate 5 and the housing 6. The locking component 9 includes a slot 91 opened on the top of one side of the rotating plate 5. A locking pin 92 is slidably connected to the inner cavity of the slot 91. A spring 93 is welded between the locking pin 92 and the inner wall of the slot 91. Multiple locking pins are opened on one side of the housing 6. The locking hole 94 is compatible with the pin 92. A fastening hoop 10 is fixedly connected to the front side of the rotating plate 5 and sleeved on the surface of the shaft pin 3. A fastening screw 11 is provided through the end of the fastening hoop 10. By cooperating with the fastening hoop 10 and the fastening screw 11, the fastening hoop 10 can be tightened by turning the fastening screw 11, which can increase the friction of the rotating plate 5 on the surface of the shaft pin 3 and prevent the rotating plate 5 from rotating randomly on the surface of the shaft pin 3. During the bending of the reinforcing bar, the rotating plate 5 will be driven to rotate through the limiting plate 7 and the sleeve 6 to ensure the stability of the limiting state.
[0023] Working principle: When using this utility model, the reinforcing bar is placed in the grooves on the two supporting pulleys 4, and then the limiting plate 7 is pressed down. The limiting plate 7 drives the sleeve 6 to slide on the surface of the rotating plate 5 until the limiting plate 7 is attached to the surface of the reinforcing bar. During the sliding of the sleeve 6, the locking hole 94 on the sleeve 6 will contact the arc surface of the locking pin 92, causing the locking pin 92 to slide into the inner cavity of the slot 91 and squeeze the locking hole 94. When the limiting plate 7 moves to the position, it is locked by the locking component 9. During the bending of the reinforcing bar, it will drive the supporting pulleys 4 to rotate. The bent reinforcing bar will also drive the sleeve 6 and the rotating plate 5 to rotate around the shaft pin 3 through the limiting plate 7, preventing the reinforcing bar from slipping out of the groove on the surface of the supporting pulley 4. Moreover, operating the handwheel 85 can make the bidirectional threaded rod 81 rotate, thereby causing the two threaded sleeves 82 to move towards and away from each other. Through the sliding of the connecting block 83 in the inner cavity of the groove 84, the two supporting pulleys 4 are driven to move towards and away from each other, thereby improving the adaptability of the support device.
[0024] In summary, this support device for detecting rebar bending works by placing the rebar in the grooves on two support pulleys 4, then pressing down on the limiting plate 7. The limiting plate 7 causes the sleeve 6 to slide on the surface of the rotating plate 5 until the limiting plate 7 is in contact with the surface of the rebar. The limiting plate 7 is then locked by the locking component 9. During the bending process of the rebar, the support pulleys 4 will rotate. The bent rebar will also cause the sleeve 6 and the rotating plate 5 to rotate around the pivot pin 3 through the limiting plate 7, preventing the rebar from slipping out of the grooves on the surface of the support pulleys 4. This achieves the purpose of protecting and limiting the rebar, preventing slippage during the bending process, and ensuring a safe testing environment.
