Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and more specifically to a prestressed concrete steel bar bending detection device. Background Technology

[0002] Prestressed concrete reinforcement is a type of steel reinforcement used in concrete structures. It improves the performance of concrete structures by applying tension in advance. Prestressing technology is mainly used to improve the crack resistance, stiffness, and load-bearing capacity of concrete members, reduce crack width, and extend the service life of structures. Reinforcing bars used in concrete usually need to undergo bending tests before use.

[0003] Existing testing devices typically place the rebar between a bending mandrel and a clamping arm. The clamping arm is then adjusted via a pressing mechanism to press the rebar firmly onto a working disc. A drive mechanism rotates the working disc, causing the pressure head on the disc to bend the rebar, thus achieving the purpose of rebar bending detection. However, during prolonged use, the pressing mechanism may become loose due to wear and tear on its components, resulting in insufficient pressure. This prevents the clamping arm from providing enough pressure to firmly press the rebar onto the working disc, and the rebar may pop out during bending due to the force, posing a certain safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a prestressed concrete steel bar bending detection device to solve the problems existing in the background art.

[0005] The utility model provides the following technical solutions:

[0006] A prestressed concrete rebar bending detection device includes a workbench with a working disc on its top surface. The top surface of the workbench is also equipped with a driving component and a clamping component.

The device also includes a top cover, a rotating component, and a positioning component on the top surface of the workbench. The rotating component is located on one side of the top cover, and the positioning component is connected to the rotating component. The top cover is positioned by the positioning component after it has rotated through the rotating component.

[0007] The positioning component includes: a fixed frame, which is fixedly connected to the top surface of the workbench. The inner bottom wall of the fixed frame has two sliding holes. A first stop bar and a second stop bar are movably connected inside the two sliding holes, respectively. An operating cavity is provided inside the workbench. A movable plate is slidably connected inside the operating cavity. One end of the first stop bar and the second stop bar respectively penetrates through the workbench and is fixedly connected to the movable plate inside the operating cavity.

[0027] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0028] Figures 1-10 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 10 The present invention will be further described below.

[0029] A prestressed concrete rebar bending testing device includes a workbench 1, a working disc 17 on the top surface of the workbench 1, a driving component and a pressing component on the top surface of the workbench 1, the driving component driving the pressing component to press the rebar onto the bending center of the working disc 17, a top cover 2, a rotating component and a positioning component on the top surface of the workbench 1, the rotating component being located on one side of the top cover 2, the positioning component being connected to the rotating component, the top cover 2 being positioned by the positioning component after being rotated by the rotating component, the positioning component including: a fixed frame 7, the fixed frame 7 being fixedly connected to the top surface of the workbench 1, two sliding holes 25 being opened in the inner bottom wall of the fixed frame 7, a first stop bar 10 and a second stop bar 11 being movably connected inside the two sliding holes 25 respectively, an operating cavity 12 being opened inside the workbench 1, a moving plate 13 being slidably connected inside the operating cavity 12, one end of the first stop bar 10 and the second stop bar 11 respectively penetrating the workbench 1 and being fixedly connected to the moving plate 13 inside the operating cavity 12.

[0030] Specifically, the positioning components also include: two fixing rods 14, both of which are fixedly connected to the inner bottom wall of the operating cavity 12, the top surface of the fixing rods 14 being fixedly connected to the inner top wall of the operating cavity 12, a return spring 15 being fixedly connected to the bottom surface of the moving plate 13, one end of the return spring 15 being fixedly connected to the inner bottom wall of the operating cavity 12, and a moving rod 16 being provided on the top surface of the worktable 1, one end of the moving rod 16 extending into the interior of the operating cavity 12 and being fixedly connected to the moving plate 13.

[0031] In this embodiment, before bending the reinforcing bar, the worker can press down on the movable rod 16. The movable rod 16 moves downward and drives the movable plate 13 to move on the outer wall of the fixed rod 14, while simultaneously squeezing the return spring 15. The downward movement of the movable plate 13 will drive the first stop bar 10 and the second stop bar 11 to move until the first stop bar 10 and the second stop bar 11 are completely inside the sliding hole 25. Then the worker can flip the top cover 2. The top cover 2 can rotate by rotating the first connecting rod 4 inside the fixed block 3. After the top cover 2 is opened to a certain angle, the movable block 6 moves to fit against the inner side wall of the fixed frame 7. Then the worker releases the movable rod 16. The potential energy of the return spring 15 is released, which drives the movable plate 13, the first stop bar 10 and the second stop bar 11 to return to their original positions. This allows the first stop bar 10 to block the movable block 6, thus keeping the top cover 2 open, allowing the worker to put the reinforcing bar into the working plate 17 and adjust its position.

[0032] Specifically, the driving components include: a connecting seat 22, which is fixedly connected to the top surface of the worktable 1, and a threaded rod 23 is threadedly connected inside the connecting seat 22; a drive motor 18 is fixedly connected to the inner top wall of the worktable 1, and the drive shaft of the drive motor 18 passes through the worktable 1 and is fixedly connected to the work plate 17; a control console 24 is fixedly connected to the top surface of the worktable 1, and the drive motor 18 is electrically connected to the control console 24; the clamping components include: a clamping arm 21, which is located on the top surface of the work plate 17, and is rotatably connected to one end of the threaded rod 23; a fixed seat 20 is fixedly connected to the top surface of the worktable 1, and the top surface of the fixed seat 20 has several circular grooves adapted to the clamping arm 21, which are rotatably connected to the clamping arm 21; and the top surface of the work plate 17 has multiple slots, one of which has a pressure head 19 movably inserted inside.

[0033] In this implementation scheme, through the set working disc 17, the operator can place the steel bar between the bending center of the working disc 17 and the clamping arm 21. At this time, the threaded rod 23 is rotated. Since the connecting seat 22 is threadedly connected to the threaded rod 23, the threaded rod 23 moves and pushes one end of the clamping arm 21 to squeeze the steel bar until the steel bar is pressed to the bending center of the working disc 17. Then the operator can adjust the position of the pressure head 19 so that the pressure head 19 contacts one end of the steel bar. Then the drive motor 18 is turned on through the control console 24. The drive shaft of the drive motor 18 rotates, which drives the working disc 17 and the pressure head 19 to rotate. Thus, the working disc 17 rotates, driving the pressure head 19 to rotate and bend one end of the steel bar, causing the steel bar to bend under force, achieving the effect of steel bar bending detection.

[0034] Specifically, the rotating component includes two fixed blocks 3, both of which are fixedly connected to the top surface of the workbench 1, and first connecting rods 4 are fixedly connected to both sides of the top cover 2, and the first connecting rods 4 are rotatably connected to the fixed blocks 3.

[0035] In this embodiment, the top cover 2 can rotate inside the fixing block 3 by rotating the first connecting rod 4, thereby facilitating the opening or closing of the top cover 2.

[0036] Specifically, the rotating component also includes: a movable block 6, which is slidably connected inside the fixed frame 7, and a second connecting rod 5 is rotatably connected to one side of the movable block 6. A limit rod 9 is fixedly connected inside the fixed frame 7, and the limit rod 9 is slidably connected to the inside of the movable block 6.

[0037] In this embodiment, when the top cover 2 is opened or closed, the top cover 2 will drive the moving block 6 to slide inside the fixed frame 7 via the second connecting rod 5. When the moving block 6 slides, it will move on the outer wall of the limiting rod 9. The limiting rod 9 limits the moving block 6, allowing the moving block 6 to move in a straight line, thus ensuring the stability of the moving block 6.

[0038] Specifically, a bearing 8 is embedded in one side of the top cover 2, and the inner ring of the bearing 8 is rotatably connected to one end of the second connecting rod 5.

[0039] In this embodiment, the bearing 8 is provided so that the second connecting rod 5 can rotate inside the bearing 8 when the top cover 2 rotates, thus ensuring the stability of the second connecting rod 5 during rotation.

[0040] The working principle and usage process of this utility model are as follows: Before bending the steel bar, the operator can press down the moving rod 16. The moving rod 16 moves downward and drives the moving plate 13 to move on the outer wall of the fixed rod 14, while simultaneously squeezing the return spring 15. The downward movement of the moving plate 13 will drive the first stop bar 10 and the second stop bar 11 to move until the first stop bar 10 and the second stop bar 11 are completely inside the sliding hole 25. Then the operator can flip the top cover 2. The top cover 2 can rotate by rotating the first connecting rod 4 inside the fixed block 3. At the same time, when the top cover 2 rotates, one end of the second connecting rod 5 rotates inside the bearing 8, while the other end of the second connecting rod 5 drives the moving block 6 to move inside the fixed frame 7 until the moving block 6 moves to fit against the inner side wall of the fixed frame 7. Then the operator releases the moving rod 16. The potential energy of the return spring 15 is released, which drives the moving plate 13, the first stop bar 10 and the second stop bar 11 to reset, so that the first stop bar 10 can block the moving block 6, thereby keeping the top cover 2 in the open state.

[0041] With the top cover 2 open, the worker can place the rebar between the bend of the working disc 17 and the clamping arm 21. Then, rotating the threaded rod 23, connected to the connecting seat 22, moves the threaded rod 23, pushing one end of the clamping arm 21 to press the rebar until it reaches the bend of the working disc 17. The worker can then adjust the position of the pressure head 19 so that it contacts one end of the rebar. Next, the worker can press down on the moving rod 16 again. The moving rod 16 moves downwards, causing the moving plate 13 to move on the outer wall of the fixed rod 14, simultaneously pressing the return spring 15. The downward movement of the moving plate 13 causes the first stop bar 10 and the second stop bar 11 to move. The first stop bar 10 and the second stop bar 11 are fully inserted into the sliding hole 25. At this point, the obstruction to the moving block 6 is released, and the operator can close the top cover 2. At this time, one end of the second connecting rod 5 drives the moving block 6 to move inside the fixed frame 7 until the moving block 6 moves to fit against the inner side wall of the fixed frame 7. The operator then releases the moving rod 16, and the potential energy of the reset spring 15 is released, causing the moving plate 13, the first stop bar 10, and the second stop bar 11 to reset. This allows the second stop bar 11 to block the moving block 6, so that the top cover 2 can protect the operator. If the steel bar pops out during processing, the top cover 2 can block the steel bar to ensure safety during processing. Then, the drive motor 18 is turned on through the control console 24. The drive shaft of the drive motor 18 rotates, which drives the working plate 17 and the pressure head 19 to rotate. The rotation of the working plate 17 drives the pressure head 19 to rotate and bend one end of the steel bar, causing the steel bar to bend under force, thus achieving the effect of steel bar bending detection.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
