Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof test of concrete test blocks for explosion-proof walls, and specifically relates to a simple detection device for concrete explosion-proof walls. Background Technique

[0002] An explosion-proof wall, also known as an anti-explosion wall, has the ability to resist explosion shock waves and can limit the destructive effect of an explosion within a certain range. Compared with a reinforced concrete explosion-proof wall, it has the advantages of light weight, easy installation and disassembly, and recyclability.

[0003] Due to the production requirements of the explosion-proof wall, it is necessary to ensure a certain explosion-proof and compressive performance. Therefore, it is necessary to place the concrete test block on the detection platform and impact it with a metal hammer to detect the impact test effect of the concrete test block. However, when the metal hammer is performing stamping work, the force of stamping will change due to falling from different heights and its own weight. Moreover, the existing metal hammers are individual, which can only ensure the concrete explosion-proof detection with one stamping strength, resulting in low efficiency of concrete explosion-proof testing.

[0004] Therefore, we propose a simple detection device for concrete explosion-proof walls. Content of the Utility Model

A handle 6 is fixedly connected to the upper surface of the heavy metal part 5. A storage groove 7 is formed on the lower surface of the heavy metal part 5. Two pipes 8 are fixedly installed on both the left and right sides of the upper surface of the base 1. Motors 9 are fixedly installed on the upper surfaces of the two pipes 8. Threaded rods 10 are rotatably arranged between the upper and lower inner walls of the two pipes 8. A threaded pipe 11 is threadedly connected to the outer surface of the threaded rod 10. A support plate 12 is fixedly connected to the outer surface of the threaded pipe 11. A fixing plate 14 is movably installed between the two pipes 8. A hydraulic cylinder 15 is fixedly installed on the upper surface of the fixing plate 14. The output end of the hydraulic cylinder 15 is fixedly connected to a clamping plate 16. A sensor 17 is fixedly installed on the upper surface of the base 1. Brackets 18 are fixedly connected to the front and rear sides of the base 1 and on the outer surfaces of the pipes 8. A limiting plate 19 is fixedly connected to the side of the bracket 18 close to the center of the base 1.

[0025] Specifically, through the cooperation among structures such as the base 1, the pressure detection device platform 2, the metal hammer 3, the placement groove 4, the heavy metal parts 5, the handle 6, the storage groove 7, the pipes 8, the motors 9, the threaded rods 10, the threaded pipes 11, the support plates 12, the sliding grooves 13, the fixing plate 14, the hydraulic cylinder 15, the clamping plate 16, the sensor 17, the brackets 18, and the limiting plate 19, the metal hammer 3 can be horizontally dropped at different heights to impact the concrete test block on the detection platform, and the weight of the metal hammer 3 can be adaptively increased or decreased, so as to test the concrete under different pressures and improve the detection efficiency of the concrete.

[0026] In this implementation scheme: The sensor 17 is correspondingly electrically connected to the four motors 9. Card slots are formed on both the left and right sides of the outer surface of the metal hammer 3. The clamping plate 16 is correspondingly clamped with the card slots. The other end of the support plate 12 is fixedly connected to the corresponding surface of the fixing plate 14.

[0027] Specifically, the sensor 17 is an existing structure, and the control circuit can be realized by simple programming of those skilled in the art. It belongs to the common knowledge in the field. Only its use is involved without modification, so the control method and circuit connection will not be described in detail. The sensor 17 can start and operate the four motors 9 simultaneously.

[0028] In this implementation scheme: The support plate 12 is correspondingly slidably arranged with the sliding groove 13. The output end of the motor 9 is fixedly connected to the upper surface of the threaded rod 10. The limiting plate 19 is correspondingly arranged with the outer surface of the metal hammer 3. The storage groove 7 is correspondingly arranged with the handle 6.

[0029] Specifically, the motor 9 drives the threaded rod 10 to rotate forward and backward, and the threaded rod 10 can be horizontally moved up and down through the support plate 12 and the chute 13 on the pipeline 8, so as to move the fixed plates 14 on both sides in the same horizontal plane.

[0030] Working principle: When the blast-proof wall concrete test block needs to be subjected to an anti-explosion impact test, the hydraulic cylinders 15 on the fixed plates 14 on both sides are started simultaneously. The two hydraulic cylinders 15 push the clamping plate 16 to be clamped with the card slot on the metal hammer 3. Then, the four motors 9 are controlled by the sensor 17 to drive the threaded rods 10 in the four pipelines 8 to rotate forward simultaneously. The threaded rods 10 can drive the threaded pipes 11 to move. The threaded pipes 11 are horizontally and limitedly moved upward through the support plates 12 and the chutes 13 on the pipelines 8. The hydraulic cylinders 15 on the fixed plates 14 are moved upward through the support plates 12. The hydraulic cylinders 15 move the metal hammer 3 upward through the clamping plate 16 and the card slot, and the metal hammer 3 is horizontally moved upward in contact with the outer limiting plate 19. The limiting plate 19 is supported by the bracket 18. Then, after moving to the specified height, the concrete test block can be placed on the pressure detection device platform 2. Then, the two hydraulic cylinders 15 simultaneously pull the clamping plate 16 out of the card slot. After the metal hammer 3 loses the supporting force, it drops downward and impacts vertically through the limiting plate 19 to impact the concrete test block on the pressure detection device platform 2. The impact pressure intensity is detected by the pressure detection device platform 2, and then the effect after the concrete impact is checked and the data is recorded. When the next concrete detection work needs to be carried out, different numbers of heavy metal parts 5 can be added to the placement groove 4 of the metal hammer 3. The heavy metal parts 5 are taken and lifted by the handle 6. Through the up-and-down fitting method of multiple heavy metal parts 5, the handle 6 is sleeved by the storage groove 7 of the heavy metal parts 5 to ensure the stability of the heavy metal parts 5 in the placement groove 4. Then, the motor 9 can drive the threaded pipe 11 to reverse, and the threaded pipe 11 and the support plate 12 are moved downward through the reverse rotation of multiple threaded pipes 11. At the same time, the hydraulic cylinders 15 on the fixed plates 14 are also moved downward. The clamping plate 16 on the hydraulic cylinder 15 is aligned with the card slot on the metal hammer 3, and then after being clamped, it can be raised for the next stamping work.

[0032] Please refer to Figures 1-2 On the basis of Embodiment 1, the present invention provides a technical solution:

[0033] In this embodiment: A bottom plate 20 is fixedly connected to the front surface of the base 1. A notch 21 is formed in the upper surface of the bottom plate 20. A damping rod 22 is fixedly installed on the lower inner wall of the notch 21. A top plate 23 is fixedly connected to the upper surface of the damping rod 22. A damping spring 24 is fixedly connected between the lower surface of the top plate 23 and the lower inner wall of the notch 21. Two baffle plates 25 are fixedly connected to the upper surface of the bottom plate 20. A plurality of sliding rods 26 are rotatably arranged on the upper surface of the bottom plate 20.

[0034] Specifically, through the cooperation among structures such as the bottom plate 20, the notch 21, the damping rod 22, the top plate 23, the damping spring 24, the baffle plates 25, and the sliding rods 26, the concrete test block can be stably placed on the bottom plate 20 and then horizontally pushed onto the detection platform, improving the feeding efficiency of the concrete test block pressure test.

[0035] In this implementation scheme: The sliding rods 26 are arranged in a linear array between the two baffle plates 25, and the top plate 23 and the notch 21 are arranged in correspondence.

[0036] Specifically, the top plate 23 can be moved and stored in the notch 21. [[ID=**11]]

[0037] Working principle: When performing the stamping work on the explosion-proof wall concrete, place the concrete test block on the top plate 23 of the bottom plate 20. Through the contraction of the damping spring 24 and the damping rod 22 at the bottom of the top plate 23, the concrete test block on the top plate 23 is stably placed on the bottom plate 20. The bottom plate 20 moves down into the notch 21 to make the concrete fit the surface of the bottom plate 20. Then, place the concrete between the two baffle plates 25 and then conveniently push and convey it from the multiple sliding rods 26 to stably convey the concrete test block to the pressure detection device platform 2. After the top plate 23 loses pressure, drive the damping spring 24 through the damping rod 22 to stably reset and push the top plate 23 back to the notch 21 for reset.
