Description

Technical Field

[0001] The present invention belongs to the technical field of building material equipment, and particularly relates to a building material testing device. Background Art

[0002] Building materials are the general term for materials used in civil engineering and construction engineering. Building materials can be divided into structural materials, decorative materials, and special materials. Before a large number of building materials are put into use, it is necessary to test the materials.

[0003] For example, Chinese Utility Model CN221351030U discloses an impact resistance test device for building material testing. The impact cylinder is used to pull the moving plate and the impact frame upward to the testing height, and then the moving plate drives the impact frame and the impact plate to move downward to impact the building material. At the same time, the impact resistance test of the building material at different heights can be realized by adjusting the different heights of the upward movement of the moving plate.

[0004] However, in the above-mentioned prior art, the impact strength at different heights is adjusted by adjusting the impact frame, so that the column needs to meet a certain length, resulting in a relatively high overall height and large volume, which affects the convenience of overall use. Summary of the Invention

[0005] The purpose of the present invention is to provide a building material testing device.

The top plate is connected with a driving device for driving the guide rod to move through the driving device, compressing the spring by the guide rod, and generating a downward acceleration driving effect on the impact rod through the elastic potential energy stored in the spring.

[0010] As a preferred technical solution of the present invention, the driving device includes a mounting bracket, a transmission shaft rotatably connected to the mounting bracket, and a driving motor fixedly connected thereto. The transmission shaft is in transmission connection with the driving motor, and a gear is fixedly connected to the transmission shaft.

[0013] As a preferred technical solution of the present invention, a transmission gear is rotatably connected to the layer board, and racks meshing with the transmission gear are fixedly connected to both clamping blocks for keeping the two clamping blocks moving synchronously.

[0014] As a preferred technical solution of the present invention, the layer board is slidably connected to the frame.

[0015] As a preferred technical solution of the present invention, a cushion block for placing the building material to be detected is arranged on the bottom plate.

Specific embodiments

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

[0034] Please refer to Figures 1 to 3 As shown, the present invention is a building material testing device, including a bottom plate 1 and a frame 101 having a top plate 2. The bottom plate 1 is provided with a cushion block 108 for placing the building material to be tested. The top plate 2 is fixedly connected with a driving guide cylinder 3 and two telescopic devices 201, and is connected with a layer plate 4 through the two telescopic devices 201 for driving the layer plate 4 to move up and down through the two telescopic devices 201, and the layer plate 4 is slidably connected with the frame 101 through a guide rail slider assembly, so as to improve the stability of the layer plate 4.

[0035] As Figure 3 、 4 and shown in 7, the layer plate 4 is provided with a linear bearing, and a shock rod 5 is movably inserted through the linear bearing, and is connected with a clamping mechanism for clamping and fixing the shock rod 5. The clamping mechanism includes two symmetrically arranged telescopic cylinders 401. The telescopic cylinder 401 can be a pneumatic cylinder, an electric push rod or a hydraulic cylinder. The telescopic end of the telescopic cylinder 401 is fixedly connected with a clamping block 402. The clamping block 402 is provided with an arc-shaped clamping groove 403 adapted to the shock rod 5. By pushing the clamping block 402 by the two telescopic cylinders 401, the two clamping blocks 402 clamp and fix the shock rod 5.

[0036] As a preferred embodiment, as Figure 9As shown, two transmission gears 404 are rotatably connected to the laminate 4, and the two transmission gears 404 are respectively located on both sides of the impact rod 5. Two clamping blocks 402 are fixedly connected with racks 405 meshing with the transmission gears 404, that is, the two racks 405 on the clamping blocks 402 respectively mesh with the two transmission gears 404. When one clamping block 402 moves, the transmission gear 404 is driven to rotate through the rack 405, and the transmission gear 404 drives the rack 405 connected to the other clamping block 402 to move, so that the two clamping blocks 402 move synchronously, ensuring that the two clamping blocks 402 can apply symmetric clamping forces to the impact rod 5, which is beneficial to ensuring the fixing effect of the impact rod 5.

[0037] Among them, an impact block 501 is connected to the lower end of the impact rod 5, which is used to clamp the impact rod 5 through the clamping mechanism. The laminate 4 is driven to move upward by the telescopic device 201, so that the upper end of the impact rod 5 is inserted into the driving guide cylinder 3, and a downward pre-pressure is applied to the impact rod 5 through the driving guide cylinder 3. When the clamping mechanism releases the impact rod 5, the impact rod 5 accelerates downward to realize the impact detection of building materials, thus avoiding the need to adjust the height of the impact rod to meet the impact detection under different conditions, effectively reducing the overall height of the detection device, reducing the overall volume, and effectively improving the overall use convenience.

[0038] As Figure 6 shown, the driving guide cylinder 3 is a cylindrical structure with an open lower end. A piston 301 is connected inside the driving guide cylinder 3, and an air pipe interface 302 is connected to the side wall of the driving guide cylinder 3. The air pipe interface 302 is connected to a compressed air source. After the clamping mechanism clamps the impact rod 5, the laminate 4 is driven to move upward by the telescopic device 201, so that the upper end of the impact rod 5 is inserted into the driving guide cylinder 3 and abuts against the lower surface of the piston 301. At this time, compressed air is introduced into the driving guide cylinder 3, and a pre-pressure is applied to the upper end of the impact rod 5 by using the piston 301.

[0039] After the building material to be detected is placed, the impact rod 5 is released by the clamping mechanism, and the piston 301 pushes the impact rod 5 downward, so that the impact rod 5 obtains an additional acceleration. Moreover, by controlling the pressure of the compressed air introduced into the driving guide cylinder 3, the additional acceleration obtained by the impact rod 5 is accurately controlled, so that the impact rod 5 can meet the impact detection under various conditions without changing the height.

[0040] As another implementation manner, as Figure 4 、 5 and 8 shown, a movable block 303 and a spring 304 are arranged inside the driving guide cylinder 3. A guide rod 202 is movably inserted through the top plate 2, and the lower end of the guide rod 202 is inserted into the driving guide cylinder 3, and the spring 304 is located between the guide rod 202 and the movable block 303.

[0041] The top plate 2 is connected with a driving device for driving the guide rod 202 to move through the driving device. For example, the driving device includes a mounting bracket 102 installed on the top plate 2, the mounting bracket 102 is rotatably connected with a transmission shaft 103, and a driving motor 104 is fixedly connected. The transmission shaft 103 is in transmission connection with the driving motor 104, and a gear 105 is fixedly connected to the transmission shaft 103.

[0042] Among them, the guide rod 202 is a cylindrical rack meshing with the gear 105. By driving the gear 105 to rotate through the driving motor 104, the guide rod 202 is driven to move up and down by the gear 105. For example, when the laminate 4 moves up, after the upper end of the impact rod 5 is inserted into the driving guide cylinder 3, the guide rod 202 is driven to move down by the rotation of the gear 105, so as to compress the spring 304 by the guide rod 202, so that the spring 304 stores a certain amount of elastic potential energy. When the clamping mechanism releases the impact rod 5, the elastic potential energy stored by the spring 304 generates a downward acceleration driving effect on the impact rod 5. That is, the spring 304 pushes the impact rod 5 downward through the movable block 303, so that the impact rod 5 obtains an additional acceleration. The pre-pressure obtained by the impact rod 5 can be flexibly controlled by the compression degree of the spring 304 by the guide rod 202.

[0043] Moreover, a worm gear 106 is fixedly connected to the transmission shaft 103, and a worm 107 meshing with the worm gear 106 is connected to the output shaft of the driving motor 104, so that the driving motor 104 realizes transmission through the worm 107 and the worm gear 106, drives the gear 105 to rotate, and utilizes the self-locking property of the worm 107 and the worm gear 106 to better keep the position fixed after the guide rod 202 compresses the spring 304.

[0044] As a preferred embodiment, as Figure 1 、 2 shown in FIG. 6, the frame 101 is connected with symmetrically arranged linear driving devices 109. The linear driving devices 109 can be cylinders or electric push rods. Opposite ends of the telescopic rods of the two linear driving devices 109 are both connected with U-shaped baffles 110.

[0045] During detection, the U-shaped baffles 110 are pushed by the linear driving devices 109, so that the two U-shaped baffles 110 enclose a rectangular frame structure, so that the building materials to be detected are enclosed inside by the cooperation of the two U-shaped baffles 110, realizing the blocking of the fragments generated during impact detection and avoiding the situation of fragment or particle splashing, which is beneficial to improving the safety and reliability of use.
