Technical Field

[0001] The utility model belongs to the technical field of concrete steel structure pressure detection, and particularly relates to a concrete steel structure pressure detection device. Background Art

[0002] The concrete steel structure is a new type of structure composed of two different materials, steel and concrete. It gives full play to the advantages of high tensile strength, good plasticity of steel and good compressive performance of concrete. The concrete steel structure needs to be subjected to pressure detection to ensure its safety and reliability. To sum up, the problems existing in the prior art are as follows: The pressure detection of the concrete steel structure is usually carried out by using a concrete pressure testing machine. It adopts the method that the action force and the reaction force are equal and opposite in direction, and uses two extrusion plates to extrude the test material. When the material deforms, the pressure change will be measured. Usually, the test material is directly placed on the extrusion bottom plate without any limit. However, when the material is tested, it needs to be in a specific position and in a vertical state. If there is no limit, it is easy for the material to displace during the detection process, which will affect the accuracy of the detection result. However, the existing concrete pressure testing machine does not have a component for stably extruding the clamped test material. Therefore, a concrete steel structure pressure detection device is specifically proposed to solve the above problems. Summary of the Invention

It adopts the method that the action force and the reaction force are equal and opposite in direction, and uses two extrusion plates to extrude the test material. When the material deforms, the pressure change will be measured. Usually, the test material is directly placed on the extrusion bottom plate without any limit. However, when the material is tested, it needs to be in a specific position and in a vertical state. If there is no limit, it is easy for the material to displace during the detection process, which will affect the accuracy of the detection result. However, the existing concrete pressure testing machine does not have a component for stably extruding the clamped test material.

[0004] The utility model is realized as follows: A concrete steel structure pressure detection device includes a concrete pressure testing machine and an extrusion top plate. The extrusion top plate is arranged in the inner cavity of the concrete pressure testing machine. An extrusion base is arranged in the inner cavity of the concrete pressure testing machine. A regulating frame is fixedly connected to the inner cavity of the extrusion base. An extrusion bottom plate is fixedly connected to the top of the regulating frame. Two device shells are movably connected to the inner cavity of the regulating frame. A control rod is movably connected to the bottom of the inner cavity of the device shell through a rotating shaft. The top of the control rod penetrates through the device shell and extends to the outside of the inner cavity of the device shell. A limiting device is arranged inside the device shell.

[0005] Preferably, the limiting device of the utility model comprises two limiting blocks. One side of each of the two limiting blocks penetrates through the device housing and extends to the outside of the inner cavity of the device housing. A moving hole is formed in the surface of the limiting block. Springs are fixedly connected to one side of each of the two limiting blocks. One side of each of the two springs is fixedly connected to the inner cavity of the device housing. By providing the limiting device, when the clamping plate moves to a position in contact with the material, the limiting device has a limiting effect on the position of the clamping plate.

[0006] Preferably, a moving rod that cooperates with the moving hole is fixedly connected to the inner cavity of the device housing. The surface of the moving rod is movably connected to the inner cavity of the moving hole. By providing the moving rod, when the limiting block moves, it will drive the moving hole to move along the surface of the moving rod. The cooperation of the moving hole and the moving rod has a limiting effect on the moving position of the limiting block.

[0007] Preferably, two extrusion rotating shells are movably connected to the surface of the control rod through a rotating shaft. An extrusion frame that cooperates with the extrusion rotating shell is fixedly connected to the top of the limiting block. The surface of the extrusion frame is movably connected to the inner cavity of the extrusion rotating shell. By providing the extrusion rotating shell and the extrusion frame, when the extrusion rotating shell rotates, it can generate an extrusion force on the extrusion frame and drive the extrusion frame to move. When the extrusion frame moves, it can drive the limiting block to move.

[0008] Preferably, a limiting groove that cooperates with the limiting block is formed in the inner cavity of the adjusting frame. The surface of the limiting block is in contact with the inner cavity of the limiting groove. The number of the limiting grooves is several and they are evenly distributed in the inner cavity of the adjusting frame. By providing the limiting groove, when the device housing moves to a suitable position in the adjusting frame and the control rod is released, the restoring force generated by the spring restoring its shape will drive the limiting block to snap into the inner cavity of the limiting groove. The cooperation of the limiting block and the limiting groove has a limiting effect on the position of the device housing.

[0009] Preferably, moving sliders are fixedly connected to the front side and the rear side of the device housing.

It adopts the method that the action force and the reaction force are equal and opposite in direction, and uses two extrusion plates to extrude the test material. When the material deforms, the pressure change will be measured. Usually, the test material is directly placed on the extrusion bottom plate without limitation. However, during the material test, it needs to be in a specific position and in a vertical state. If there is no limitation, it is easy for the material to displace during the test, which affects the accuracy of the test result. However, the existing concrete pressure testing machine does not have a component for stably extruding the clamped test material.

[0012] 2. By setting the limiting device, when the extrusion frame moves, it will drive the two limiting blocks to move towards the side close to each other. When the limiting blocks move, they will drive the moving holes to move along the surface of the moving rod. When the force generated by the movement of the limiting blocks causes the spring to undergo elastic deformation, the restoring force generated when the spring returns to its original shape will drive the limiting blocks to snap into the inner cavity of the limiting groove. The limiting device has a limiting effect on the position of the clamping plate. Description of the Drawings

Detailed Embodiments

[0019] To further understand the invention content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 5 shown, a concrete steel structure pressure detection device provided by an embodiment of the present utility model includes a concrete pressure testing machine 1 and an extrusion top plate 2. The extrusion top plate 2 is arranged in the inner cavity of the concrete pressure testing machine 1. An extrusion base 3 is arranged in the inner cavity of the concrete pressure testing machine 1. A regulating frame 4 is fixedly connected to the inner cavity of the extrusion base 3. An extrusion bottom plate 5 is fixedly connected to the top of the regulating frame 4. Two device shells 6 are movably connected to the inner cavity of the regulating frame 4. A control rod 7 is movably connected to the bottom of the inner cavity of the device shell 6 through a rotating shaft. The top of the control rod 7 penetrates through the device shell 6 and extends to the outside of the inner cavity of the device shell 6. A limiting device 8 is arranged inside the device shell 6.

[0022] Referring to Figure 5 , the limiting device 8 includes two limiting blocks 801. The opposite sides of the two limiting blocks 801 penetrate through the device shell 6 and extend to the outside of the inner cavity of the device shell 6. A moving hole 802 is formed on the surface of the limiting block 801. Springs 803 are fixedly connected to the opposite sides of the two limiting blocks 801. The opposite sides of the two springs 803 are fixedly connected to the inner cavity of the device shell 6.

[0023] Adopting the above scheme: By setting the limiting device 8, when the clamping plate 15 moves to the position in contact with the material, the limiting device 8 has a limiting effect on the position of the clamping plate 15.

[0024] Referring to Figure 4 , a moving rod 9 that cooperates with the moving hole 802 is fixedly connected to the inner cavity of the device shell 6. The surface of the moving rod 9 is movably connected to the inner cavity of the moving hole 802.

[0025] Adopting the above scheme: By setting the moving rod 9, when the limiting block 801 moves, it will drive the moving hole 802 to move along the surface of the moving rod 9. The cooperation of the moving hole 802 and the moving rod 9 has a limiting effect on the moving position of the limiting block 801.

[0026] Referring to Figure 4 , two extrusion rotating shells 10 are movably connected to the surface of the control rod 7 through a rotating shaft. An extrusion frame 11 that cooperates with the extrusion rotating shell 10 is fixedly connected to the top of the limiting block 801. The surface of the extrusion frame 11 is movably connected to the inner cavity of the extrusion rotating shell 10.

[0027] Adopt the above solution: By setting the extrusion rotating shell 10 and the extrusion frame 11, when the extrusion rotating shell 10 rotates, it can generate an extrusion force on the extrusion frame 11 and drive the extrusion frame 11 to move. When the extrusion frame 11 moves, it can drive the limit block 801 to move.

[0028] Reference Figure 3 , a limit groove 12 for cooperating with the limit block 801 is provided in the inner cavity of the adjustment frame 4. The surface of the limit block 801 is in contact with the inner cavity of the limit groove 12. The number of the limit grooves 12 is several and they are evenly distributed in the inner cavity of the adjustment frame 4.

[0029] Adopt the above solution: By setting the limit groove 12, when the device housing 6 moves to a suitable position in the adjustment frame 4 and the control rod 7 is released, the restoring force generated by the spring 803 restoring its shape will drive the limit block 801 to snap into the inner cavity of the limit groove 12. The cooperation between the limit block 801 and the limit groove 12 has a limiting effect on the position of the device housing 6.

[0030] Reference Figure 3 , moving sliders 13 are fixedly connected to the front side and the rear side of the device housing 6. Moving chutes 14 for cooperating with the moving sliders 13 are provided in the front side and the rear side of the inner cavity of the adjustment frame 4. The surface of the moving slider 13 is movably connected to the inner cavity of the moving chute 14.

[0031] Adopt the above solution: By setting the moving slider 13 and the moving chute 14, when the device housing 6 moves, it will drive the moving slider 13 to move along the inner cavity of the moving chute 14. The cooperation between the moving slider 13 and the moving chute 14 has a limiting effect on the moving position of the device housing 6.

[0032] Reference Figure 2 , a clamping plate 15 is fixedly connected to the top of the device housing 6. The top of the clamping plate 15 passes through the extrusion bottom plate 5 and extends to the top of the extrusion bottom plate 5.

[0033] Adopt the above solution: By setting the clamping plate 15, when the surface of the clamping plate 15 comes into contact with the surface of the material, the position of the material is restricted. The setting of the clamping plate 15 has a limiting effect on the position where the material is extruded.

[0034] Working principle of the utility model: When in use, when the concrete pressure testing machine 1 needs to stably extrude the material to be tested by clamping, first, the user places the material to be tested on the top of the extrusion bottom plate 5, and then rotates the control rod 7, driving the control rod 7 to rotate through the rotating shaft. When the control rod 7 rotates, it will drive the two extrusion rotating shells 10 to rotate along the surface of the extrusion frame 11. The extrusion rotating shells 10 will generate an extrusion force on the extrusion frame 11. The two extrusion frames 11 subjected to the extrusion force will move towards the side close to each other. When the extrusion frame 11 moves, it will drive the two limit blocks 801 to move towards the side close to each other. When the limit blocks 801 move, they will drive the moving holes 802 to move along the surface of the moving rod 9. When the force generated by the movement of the limit blocks 801 causes the spring 803 to undergo elastic deformation. When the limit blocks 801 completely move into the inner cavity of the device housing 6, move the device housing 6 towards the side close to the material. When the device housing 6 moves, it will drive the moving slider 13 to move along the inner cavity of the moving chute 14, and at the same time drive the two clamping plates 15 to move towards the side close to the material. When the two clamping plates 15 contact the surface of the material, release the two control rods 7. The restoring force generated by the spring 803 restoring its shape will drive the limit blocks 801 to snap into the inner cavity of the limit groove 12. The cooperation of the limit blocks 801 and the limit groove 12 has a limiting effect on the position of the clamping plates 15. The setting of the two clamping plates 15 has a limiting effect on the position of the material. At this time, the concrete pressure testing machine 1 can complete the clamping of the material to be tested and perform stable extrusion.

[0035] To sum up: For this concrete steel structure pressure detection device, by setting the cooperation of the limiting device 8, the limit blocks 801, the moving holes 802, the springs 803 and the limit grooves 12, it solves the problem that the pressure detection of the existing concrete steel structure usually uses a concrete pressure testing machine. It uses the way that the action force and the reaction force are equal and opposite in direction, and uses two extrusion plates to extrude the material to be tested. When the material deforms, the pressure change will be measured. Usually, the material to be tested is directly placed on the extrusion bottom plate without being limited. However, when the material is tested, it needs to be in a specific position and in a vertical state. If it is not limited, it is easy for the material to displace during the testing process, affecting the accuracy of the test results. But the existing concrete pressure testing machine does not have components for stably extruding the material to be tested.
