Description

Technical Field

[0001] This invention belongs to the field of building panel strength testing technology, specifically an impact testing device for testing the strength of building panels. Background Technology

[0002] Building panels are flat, rectangular materials widely used in the construction industry. They are mainly used to construct structures such as ceilings, floors, and walls. Before building panels are put into use, their strength needs to be tested to determine their impact resistance and ensure project quality.

[0003] Patent CN210923354U discloses a testing device for building panels, including a top plate. Support rods are installed at the four corners of the lower surface of the top plate. The bottom of each support rod is mounted on the upper surface of a base. A first hydraulic cylinder is installed at the center of the upper surface of the top plate. A first hydraulic telescopic rod is located at the bottom of the first hydraulic cylinder. The bottom of the first hydraulic telescopic rod passes through a first through hole in the top plate and connects to an electromagnetic chuck. A connecting plate is magnetically connected to the bottom of the electromagnetic chuck. Hollow cylindrical tubes are installed at the four corners of the outer wall of the connecting plate, and sliding rods are installed inside the hollow cylindrical tubes. This patent can test the impact resistance of building materials. It can test the impact resistance of building panels by allowing weights of different weights to be dropped freely from different horizontal heights. It can fix building panels of different lengths and thicknesses, making it highly versatile and practical.

However, when the dent is minor and not very noticeable, it may be difficult for workers to visually observe its specific condition, thus affecting the accurate judgment of the board's strength.

The impact testing equipment for strength testing of building panels described in this invention utilizes a covering component to automatically adhere tape to the surface of the panel until the tape completely covers the pigment on the panel surface. When multiple panels are stacked, the pigment on the panel surface will not be rubbed off due to the isolation provided by the tape, facilitating subsequent observation. Attached Figure Description

[0022] Please refer to Figures 1-11The present invention provides a technical solution: an impact testing device for strength testing of building panels, including a test bench 1, two guide rods 29 fixedly connected to one side of the upper surface of the test bench 1, a counterweight box 30 slidably connected to the two guide rods 29, an electronic scale 37 provided at the bottom of the inner cavity of the counterweight box 30, a connecting frame 33 fixedly connected to one side of the bottom of the counterweight box 30, a pressure sensor provided on one side of the bottom of the connecting frame 33, an impact hammer 32 provided at the detection end of the pressure sensor, and an auxiliary observation component for dent state; The concave state auxiliary observation component includes a bracket 35 fixedly connected to one side of the upper surface of the test bench 1. A cylinder 39 is fixedly connected to the middle of the upper end of the bracket 35. A lifting plate 23 is fixedly connected to the piston end of the cylinder 39. Two sliding rods 20 are vertically slidably mounted on the upper edge of the lifting plate 23. A sponge roller 40 is fixedly connected to the lower end of the two sliding rods 20. A pigment box 38 is fixedly connected to one side of the top of the bracket 35. A pump body for extracting pigments is provided on one side of the pigment box 38. The discharge end of the pump body is connected to a pipeline. The pipeline is fixedly connected to one side of the sponge roller 40, and the pipe opening is aligned with the surface of the sponge roller 40. A positioning plate 6 is slidably connected to one side of the upper surface of the test bench 1 through a sliding groove. Clamping blocks 24 are slidably connected to both sides of the sliding groove on the positioning plate 6.

[0023] In this embodiment, as Figures 4-9 As shown, a bracket 2 3 is fixedly connected to one side of the upper surface of the test bench 1. The upper ends of the two guide rods 29 are fixedly connected to the bracket 2 3. A winding roller 34 is rotatably connected to one side of the top of the bracket 2 3. A rope 31 is wound on the winding roller 34. The lower end of the rope 31 is fixedly connected to one side of the counterweight box 30.

[0024] A motor 35 is fixedly connected to one side of the top of the bracket 2 3. The output end of the motor 35 is fixedly connected to the rotating end of the winding roller 34. Two electromagnets 36 are provided on the top of the bracket 2 3 for adsorbing the counterweight box 30.

[0025] A threaded rod 28 is threadedly connected to one side of the positioning plate 6. Both ends of the threaded rod 28 are rotatably connected to the test bench 1. A motor 3 26 is fixedly connected to one side of the test bench 1. The output end of the motor 3 26 is fixedly connected to one end of the threaded rod 28. A bidirectional threaded rod 25 is rotatably connected to both ends of the sliding groove of the positioning plate 6. The two sides of the bidirectional threaded rod 25 are threadedly connected to two clamping blocks 24 respectively. A motor 4 27 is fixedly connected to one end of the positioning plate 6. The output end of the motor 4 27 is fixedly connected to one end of the bidirectional threaded rod 25.

[0026] A spring 21 is fitted onto one end of the slide rod 20. One end of the spring 21 is fixedly connected to the end of the slide rod 20, and the other end is fixedly connected to the surface of the lifting plate 23.

[0027] Specifically, in the existing technology, when conducting impact tests on sheet metal, the sheet metal is usually first fixed under a weight, then the weight is raised to a certain height and released to allow it to fall freely and impact the sheet metal. Finally, the strength is judged by observing the damage to the surface of the sheet metal.

[0028] Normally, when a board is impacted, its surface will develop a dent. Workers can assess the board's strength by observing the degree of the dent. However, when the dent is minor and not very noticeable, it may be difficult for workers to visually observe its specific condition, thus affecting the accurate judgment of the board's strength.

[0029] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, the material to be tested is placed between two clamping blocks 24. Then, the motor 27 drives the bidirectional threaded rod 25 to rotate, causing the two clamping blocks 24 to come closer together and clamp the material. Next, water is injected into the counterweight box 30 according to the required weight. At the same time, the electronic scale 37 weighs the water in real time until the required counterweight is achieved, and then the box lid is closed.

[0030] Subsequently, the winding roller 34 is rotated by the motor 35, and the rope 31 is wound around the winding roller 34. The counterweight box 30 will then move upward along the guide rod 29 until the counterweight box 30 is between the two electromagnets 36, and the two sides of the counterweight box 30 are in contact with the two electromagnets 36 respectively. Then the electromagnets 36 are energized to attract the counterweight box 30.

[0031] At this point, the rope 31 is unwound to a certain length using the winding roller 34, and then the electromagnet 36 is de-energized. The counterweight box 30 will then fall freely and strike the plate material using the impact hammer 32. This cycle is repeated to achieve the impact test on the plate material.

[0032] After the impact test, motor 26 drives threaded rod 28 to rotate, causing positioning plate 6 to slide on test bench 1 until the plate moves under sponge roller 40. Then, the pump on pigment tank 38 is activated, drawing out pigment and spraying it onto the surface of sponge roller 40 through a pipeline. Cylinder 39 then lowers sponge roller 40, which, under the action of spring 21 and slide rod 20, comes into close contact with the plate surface. Continuing to move the plate further allows pigment to be applied to its surface via sponge roller 40. Only flat areas of the plate will have pigment adhering to them; recessed areas will not, as they cannot contact sponge roller 40, and will remain unadhered until the plate has completely passed under sponge roller 40. At this point, the flat and recessed areas of the plate create a clear contrast under the effect of the pigment, making it easier for personnel to observe the location and extent of the dents, thus improving the accuracy of the plate strength assessment.

[0033] In this embodiment, as Figure 2 , Figure 10 , Figure 11 As shown, it also includes a masking component; The covering assembly includes a bracket 2 fixedly connected to one side of the upper surface of the test bench 1. A tape roll 16 is rotatably connected to one side of the bracket 2. A transverse frame 4 is provided on one side of the upper surface of the test bench 1 via a linear guide module 7. A slider 9 is slidably connected to one side of the transverse frame 4. A vacuum generator 10 is rotatably connected to one end of the slider 9. An adsorption plate 11 is fixedly connected to one side of the vacuum generator 10. Two air inlets 12 communicating with the vacuum generator 10 are provided on one side of the adsorption plate 11.

[0034] A motor 17 is fixedly connected to one side of the upper end of bracket 12. The output end of motor 17 is fixedly connected to the rotating end of tape roll 16. A linear guide module 2 14 is provided on one side of bracket 12. A gripper cylinder 13 is fixedly connected to the moving end of linear guide module 2 14.

[0035] A cutting plate 18 is fixedly connected to one side of the upper end of bracket 12, and a cylinder 2 15 is fixedly connected to one side of bracket 12. A blade 19 is fixedly connected to the piston end of cylinder 2 15.

[0036] A cylinder 8 is fixedly connected to one side of the transverse frame 4. The piston end of the cylinder 8 is fixedly connected to one end of the slider 9. A motor 22 is fixedly connected to one side of the slider 9. The output end of the motor 22 is fixedly connected to one end of the vacuum generator 10.

[0037] Specifically, in the above embodiments, although applying pigment to the surface of the board can assist personnel in observing the dents, in some cases, it is necessary to perform strength tests on multiple boards and then observe the dents together after the tests. Furthermore, for ease of collection, multiple boards are often stacked. However, during stacking, the boards tend to stick together, which can easily cause the pigment on their surfaces to be rubbed off, thus affecting subsequent unified observation.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Initially, the tape end on the tape roll 16 is hanging down. The linear guide module 14 drives the gripper cylinder 13, aligning its gripping end with the tape end. The gripper cylinder 13 then clamps the tape end and moves it downwards. Simultaneously, the motor 17 rotates the tape roll 16, unwinding a section of tape. Next, the linear guide module 7 moves the transverse frame 4, causing the adsorption plate 11 to contact the non-adhesive surface of the unwound tape. The vacuum generator 10 is then activated, adsorbing the tape through the air inlet 12. The cylinder 15 then moves the blade 19 laterally, cutting the tape with the cooperation of the blade 19 and the cutting plate 18. At this point, the motor 22 rotates the vacuum generator 10 90 degrees, turning the adhesive surface of the adsorbed tape downwards. The cylinder 8 then lowers the tape, adhering it to the surface of the board. Repeat the above steps until the tape completely covers the pigment on the surface of the board. When multiple boards are stacked, the pigment on the surface of the board will not be rubbed off due to the isolation provided by the tape, making it easier to observe later.

[0039] Working principle: First, the material to be tested is placed between two clamping blocks 24. Then, the motor 27 drives the bidirectional threaded rod 25 to rotate, causing the two clamping blocks 24 to move closer together and clamp the material. Subsequently, water is injected into the counterweight box 30 according to the required weight. At the same time, the electronic scale 37 weighs the water in real time until the required counterweight is achieved, and then the box lid is closed.

[0040] Subsequently, the winding roller 34 is rotated by the motor 35, and the rope 31 is wound around the winding roller 34. The counterweight box 30 will then move upward along the guide rod 29 until the counterweight box 30 is between the two electromagnets 36, and the two sides of the counterweight box 30 are in contact with the two electromagnets 36 respectively. Then the electromagnets 36 are energized to attract the counterweight box 30.

[0041] At this point, the rope 31 is unwound to a certain length using the winding roller 34, and then the electromagnet 36 is de-energized. The counterweight box 30 will then fall freely and strike the plate material using the impact hammer 32. This cycle is repeated to achieve the impact test on the plate material.

[0042] After the impact test, motor 26 drives threaded rod 28 to rotate, causing positioning plate 6 to slide on test bench 1 until the plate moves under sponge roller 40. Then, the pump on pigment tank 38 is activated, drawing out pigment and spraying it onto the surface of sponge roller 40 through a pipeline. Cylinder 39 then lowers sponge roller 40, which, under the action of spring 21 and slide rod 20, comes into close contact with the plate surface. Continuing to move the plate further allows pigment to be applied to its surface via sponge roller 40. Only flat areas of the plate will have pigment adhering to them; recessed areas will not, as they cannot contact sponge roller 40, and will remain unadhered until the plate has completely passed under sponge roller 40. At this point, the flat and recessed areas of the plate create a clear contrast under the effect of the pigment, making it easier for personnel to observe the location and extent of the dents, thus improving the accuracy of the plate strength assessment.

[0043] Initially, the tape end on the tape roll 16 is hanging down. The linear guide module 14 drives the gripper cylinder 13, aligning its gripping end with the tape end. The gripper cylinder 13 then clamps the tape end and moves it downwards. Simultaneously, the motor 17 rotates the tape roll 16, unwinding a section of tape. Next, the linear guide module 7 moves the transverse frame 4, causing the adsorption plate 11 to contact the non-adhesive surface of the unwound tape. The vacuum generator 10 is then activated, adsorbing the tape through the air inlet 12. The cylinder 15 then moves the blade 19 laterally, cutting the tape with the cooperation of the blade 19 and the cutting plate 18. At this point, the motor 22 rotates the vacuum generator 10 90 degrees, turning the adhesive surface of the adsorbed tape downwards. The cylinder 8 then lowers the tape, adhering it to the surface of the board. Repeat the above steps until the tape completely covers the pigment on the surface of the board. When multiple boards are stacked, the pigment on the surface of the board will not be rubbed off due to the isolation provided by the tape, making it easier to observe later.
