Description

Technical Field

[0001] The utility model belongs to the technical field of compressive strength detection, and particularly relates to a compressive strength detection device for building materials. Background Art

[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into: inorganic materials, including metal materials and non-metal materials; organic materials, including plant materials, synthetic polymer materials and asphalt materials; composite materials, including asphalt concrete, polymer concrete, etc., which are generally composed of inorganic non-metallic materials and organic materials. In order to ensure the construction quality of building projects, compressive strength detection equipment is generally required to conduct compressive tests on building materials.

[0003] A patent with the publication number of CN220473166U discloses a compressive strength detection device for building materials, including a bottom box. A belt is installed in the middle of the top end of the bottom box. Rotating rollers are rotatably arranged on both sides inside the belt. A driving motor is fixedly installed inside the bottom box. The output shaft of the driving motor is rotationally connected to the rotating roller through an engaged chain; A vertical plate is fixedly arranged on the top of the bottom box. A hydraulic cylinder is fixedly installed on the top of the vertical plate. The output shaft of the hydraulic cylinder is clamped and connected to a pressing plate. Soft cloth belts are fixedly arranged at both ends of the pressing plate. Counterweight bars are fixedly arranged at the bottoms of the two soft cloth belts; A hydraulic push rod is fixedly installed on the vertical plate. The output shaft of the hydraulic push rod is fixedly provided with a first clamping plate. The second clamping plate is fixedly arranged on the top of the bottom box through a triangular plate.

[0004] The applicant believes that the above scheme has the following problems: The above scheme needs to start the driving motor first before detection, and use the driving motor to drive the belt to rotate. When the belt transports the material to be detected to the specified position, the first clamping plate is pushed by starting the hydraulic push rod to clamp the material to be detected. Then, the hydraulic cylinder is used to conduct a pressure test on the clamped material to be detected. However, during the whole process, only when the material to be detected moves to the specified position can the first clamping plate and the second clamping plate be controlled to clamp the material to be detected. The first clamping plate and the second clamping plate cannot restrict the material to be detected during the process of the belt transporting the material to be detected, increasing the probability of the material to be detected shifting during the rotation of the belt. When the material to be detected shifts, the position of the material to be detected needs to be adjusted again, greatly increasing the detection time of the material to be detected and the overall practicality is relatively low. Summary of the Utility Model

[0005] To solve the problems in the background art, the utility model provides a compressive strength detection device for building materials.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0026] The driving mechanism includes a motor 6, a groove 13 is opened on the bottom inner wall of the box body 4, and the motor 6 is fixedly installed on the outer surface of the box body 4. The output shaft of the motor 6 rotates through the box body 4 and extends into the groove 13, and a lead screw 12 is fixedly arranged on the output shaft of the motor 6. One end of the lead screw 12 away from the motor 6 is rotatably connected to the side wall of the groove 13. The lead screw 12 is threadedly penetrated through the bottom of the workbench 11, and the bottom of the workbench 11 is in limiting sliding fit with the bottom inner wall of the box body 4, facilitating the sliding of the workbench 11 in the box body 4.

[0027] Two sliding grooves 19 are symmetrically opened on the workbench 11, and a clamping assembly is slidably arranged in each sliding groove 19. A transmission assembly for driving the two clamping assemblies to move towards each other or away from each other is arranged in the box body 4.

[0028] The transmission assembly includes a bidirectional lead screw 16, the bidirectional lead screw 16 is rotatably penetrated through the workbench 11 along the horizontal direction, the two clamping assemblies correspond to the two threaded sections of the bidirectional lead screw 16 one by one, and the clamping assembly is threadedly connected to the corresponding threaded section. Both ends of the bidirectional lead screw 16 rotatably penetrate through the workbench 11 and are fixedly provided with gears 9, two racks 8 are fixedly arranged in the box body 4, the two gears 9 correspond to the two racks 8 one by one, and the gear 8 meshes with the corresponding rack 9.

[0029] The sliding of the workbench 11 drives the two gears 9 to rotate, thereby driving the two clamping assemblies to approach or move away from each other on the workbench 11.

[0030] Each clamping assembly includes a slider 10, the two sliders 10 correspond to the two threaded sections of the bidirectional lead screw 16 one by one, and each slider 10 is threadedly connected to the corresponding threaded section of the bidirectional lead screw 16. The bottom of each slider 10 is located in the corresponding sliding groove 19 and is in limiting sliding fit with the corresponding sliding groove 19. A clamping plate 17 is movably arranged between the two sliders 10, the two sliders 10 correspond to the two clamping plates 17 one by one, and an elastic component is arranged between each slider 10 and the corresponding clamping plate 17.

[0031] The elastic component includes a spring 15. A slide bar 18 is slidably penetrated through the slider 10. One end of the slide bar 18 is fixedly connected to the clamping plate 17, and the other end of the slide bar 18 slidably penetrates through the slider 10 and is fixedly provided with a limit block (not shown in the figure). The spring 15 is sleeved on the outer surface of the slide bar 18. One end of the spring 15 is fixedly connected to the slider 10, and the other end is fixedly connected to the clamping plate 17. It is convenient for the clamping component to clamp materials to be detected with different sizes.

[0032] The stamping mechanism is slidably arranged along the vertical direction on the inner wall of the top of the box body 4. The stamping mechanism includes a pressure plate 14.

[0033] The working principle of the first embodiment: When it is necessary to detect the compressive strength of building materials, place the building materials on the upper surface of the workbench 11. Start the motor 6, and the output shaft of the motor 6 drives the lead screw 12 to rotate.

[0034] During the process of the workbench 11 sliding towards the inside of the box body 4, when the gear 9 meshes with the rack 8, the gear 9 will rotate. The rotation of the gear 9 will drive the bidirectional lead screw 16 to rotate. The rotation of the bidirectional lead screw 16 will drive the two sliders 10 to approach each other. During the process of the two sliders 10 approaching each other, they will drive the two clamping plates 17 to approach each other by squeezing the spring 15.

The two box doors 1 correspond to the two connecting plates 7 one by one, and each box door 1 is hinged to the end of the corresponding connecting plate 7 far away from the workbench 11. During the process of the workbench 11 sliding towards the inside of the box body 4, it will drive the two box doors 1 to close through the connecting plates 7, preventing the building materials from splashing and hurting people during the pressure detection process

[0037] The working principle of the second embodiment: During the process of the workbench 11 sliding towards the inside of the box body 4, it will pull the connecting plate 7 to slide synchronously. Thus, the two connecting plates 7 are pulled to drive the two box doors 1 to rotate. Make the box door 1 close to the opening surface of the box body 4, preventing the material to be detected from splashing and hurting people during the pressure detection.

[0038] During this process, the hinged end of the connecting plate 7 and the workbench 11 will rotate around the connection between the connecting plate 7 and the workbench 11. The hinged end of the connecting plate 7 and the cabinet door 1 will rotate around the connection between the connecting plate 7 and the cabinet door 1.
