Description

Technical Field

[0001] This invention relates to the technical field of building material testing, and in particular to a building material testing device for building construction. Background Technology

[0002] Building construction refers to the process of transforming a building from design drawings into a physical building through construction activities. It covers construction stages such as foundation engineering, main structure, roofing, and decoration, and is a core stage of the project construction implementation phase. In order to ensure the quality of building construction, testing devices are needed to test the quality of building materials. In existing technology, testing equipment uses a pressure block that moves up and down to press against the building material when testing it. A pressure sensor is used to sense the force of the press to achieve the impact resistance test of the building material. However, in actual testing, the pressure block that moves up and down only impacts a certain position of the building material to achieve the testing effect. This testing method is relatively simple and the testing accuracy needs to be improved. When it is necessary to test the impact resistance of different positions on the building material, the position of the building material needs to be readjusted. This operation is time-consuming and laborious, reducing work efficiency. Therefore, there is room for improvement. Summary of the Invention

[0015] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0016] Reference Figures 1-7 This invention discloses a building material testing device for construction, including a base plate 1 and a support plate 4. Multiple support rods 2 are connected to the middle of the base plate 1, and the top of the support rods 2 are connected to the support plate 4. The support plate 4 is in the shape of a circular plate. A fixing frame 5 is fastened to the left edge of the base plate 1 by bolts. A testing structure is provided on the fixing frame 5 through a movable lifting structure. A rotating feeding structure is provided on the support plate 4. The movable lifting structure includes vertical grooves 8 opened on the upper sides of both sides of the fixed frame 5, lifting blocks 7 are slidably arranged in the vertical grooves 8, and first electric telescopic rods 6 are installed on the left and right sides of the fixed frame 5. The bottom end of the output shaft of the first electric telescopic rods 6 is connected to the lifting blocks 7. A guide rail plate 9 is installed between the two lifting blocks 7. A movable sleeve 10 is movably sleeved on the guide rail plate 9. An installation frame 11 is set below the movable sleeve 10 through a movable structure. A detection structure is set at the bottom end of the installation frame 11. A driving structure is connected between the movable sleeve 10 and the fixed frame 5. The driving structure includes a first opening 3 in the middle of the fixed frame 5. A horizontal plate 13 is connected between the inner walls on both sides of the first opening 3. Multiple first guide grooves 15 are equally spaced on the front of the horizontal plate 13. A second guide groove 16 is opened between two adjacent first guide grooves 15 on the front of the horizontal plate 13. The second guide groove 16 is connected to the first guide groove 15. A first insertion groove 14 is opened at the upper end of the rightmost first guide groove 15. A first insert rod 12 and a second insert rod 17 are provided on the mounting frame 11 through a switching structure. The top end of the first insert rod 12 is movably inserted into the first insertion groove 14. Multiple third guide grooves 19 are equally spaced on the rear side of the horizontal plate 13. A fourth guide groove 20 is opened between two adjacent third guide grooves 19 on the rear side of the horizontal plate 13. The fourth guide groove 20 is connected to the third guide groove 19. A second insertion groove 18 is opened at the upper wall of the leftmost third guide groove 19. The switching structure includes a mounting base 21 installed on the movable sleeve 10. The mounting base 21 extends into the mounting frame 11. A second electric telescopic rod 22 is installed at the middle of the lower part of the mounting base 21. An end block 23 is installed on the bottom end of the output shaft of the second electric telescopic rod 22. A drive frame 24 is provided on the end block 23. A through plate 25 is movably passed through the mounting frame 11 near the middle. A drive groove 26 is opened on the through plate 25. The drive frame 24 movably passes through the drive groove 26. The detection structure includes a detection rod 34 fixedly connected to the middle of the lower part of the mounting frame 11. A pressure block 35 is installed on the bottom end of the detection rod 34, and a pressure sensor 36 is installed on the pressure block 35. A controller 37 is installed on the left side of the fixing frame 5 near the upper position. The pressure sensor 36 is electrically connected to the controller 37. When detecting building materials, the first electric telescopic rod 6 is activated, which drives the lifting block 7, guide rail plate 9, mounting frame 11, and pressure block 35 to move downward as a whole. During the downward movement of the mounting frame 11, the top end of the first insertion rod 12 slides from the first insertion slot 14 into the first guide slot 15. Through the compression of the first insertion rod 12 end against the wall of the first guide slot 15, the moving sleeve 10 moves to the left on the guide rail plate 9, thereby driving the mounting... The frame 11 and pressure block 35 move to the left as a whole. When the top of the first insert rod 12 slides into the vertical section of the first guide groove 15, the moving sleeve 10 remains in a fixed position on the guide rail plate 9. As the lifting block 7 continues to move downward, it can drive the pressure block 35 to press against the building material. The pressure sensor 36 senses the pressure generated during the pressing and displays it on the display screen of the controller 37 to realize the detection of the impact resistance of the building material. After detecting a certain position on the building material, the first electric telescopic rod 6 drives the lifting block 7 to move upward, thereby driving the top of the first insert rod 12 to move out of the vertical section of the first guide groove 15. The first insert rod 12 moves vertically upward and presses against the groove wall of the second guide groove 16, so that the moving sleeve 10 continues to drive the pressure block 35 on the guide rail plate 9. 5. Move to the left. When the top of the first insert rod 12 slides to the uppermost position in the second guide groove 16, the lifting block 7 moves to the highest position. Then, the first electric telescopic rod 6 drives the lifting block 7 and the first insert rod 12 to move down. The moving first insert rod 12 presses against the lower wall of the corresponding first guide groove 15. As the first insert rod 12 continues to move down, the moving sleeve 10 continues to move to the left on the guide rail plate 9. In this way, when the lifting block 7 drives one end of the first insert rod 12 to slide in the corresponding first guide groove 15, it can drive the pressure block 35 to perform detection work on different positions on the building materials, thereby improving the detection accuracy and making the operation more labor-saving and convenient. When the moving sleeve 10 moves to the leftmost position on the guide rail plate 9 and the lifting block 7 is at the lowest position, it can be started. The second electric telescopic rod 22 drives the driving frame 24 to slide downward in the driving groove 26. The pressure of the driving frame 24 against the groove wall of the driving groove 26 pushes the through plate 25 to move on the mounting frame 11, thereby pulling the top end of the first insert rod 12 out of the first guide groove 15 corresponding to the front of the horizontal plate 13. At this time, the driving frame 24 moves down half its height. Then, the first electric telescopic rod 6 drives the lifting block 7 to move up to its highest position. The second electric telescopic rod 22 drives the driving frame 24 to continue moving downward in the driving groove 26. The pressure of the driving frame 24 against the groove wall of the driving groove 26 continues to push the through plate 25 to move on the mounting frame 11, thereby causing the top end of the second insert rod 17 to insert into the second insertion groove 18 on the back of the horizontal plate 13. Thus, as the lifting block 7 moves up and down...This allows the pressure block 35 to move intermittently to the right, thereby enabling the testing of the compressive strength of various locations on the next piece of building material.

[0017] See Figures 4-7 The movable structure includes a groove 33 located below the movable sleeve 10, in which a slider 32 is slidably mounted. The top of the mounting frame 11 is fixedly mounted on the slider 32, and a guide structure is provided between the slider 32 and the fixed frame 5. The guide structure includes a rotating shaft 31 rotatably connected to the middle of the lower part of the slider 32. A spherical block 30 is provided at the bottom of the rotating shaft 31, and a guide rail 27 moves through the spherical block 30. The middle section of the guide rail 27 is arc-shaped, and guide blocks 28 are installed on both ends of the guide rail 27. Guide grooves 29 for sliding of the guide blocks 28 are provided on the inner walls of both sides of the fixed frame 5. While the movable sleeve 10 moves back and forth on the guide rail plate 9, it can drive the mounting frame 11 to move on the guide rail 27. Since the upper part of the building material is arc-shaped, the mounting frame 11 drives the pressure block 35 to move on the arc-shaped guide rail 27 in the middle section, which can ensure that the pressure block 35 can be smoothly pressed to various positions on the building material for testing, thereby achieving accurate testing.

[0018] See Figures 1-3 The support plate 4 has two second openings 38, which are radially distributed on the support plate 4. One of the second openings 38 is located at the position of the fixed frame 5. A receiving frame 39 is installed on the bottom plate 1 directly below the other second opening 38. The rotary feeding structure includes a mounting plate 40 fixedly sleeved on the support rod 2. A motor 41 is installed in the middle of the mounting plate 40. A rotating block 42 is installed on the top of the output shaft of the motor 41. Multiple connecting rods 43 are connected at equal angles on the side of the rotating block 42. One end of the connecting rod 43 is fixedly connected to the inner wall of the feeding plate 44. The feeding plate 44 is set close to the support plate 4. Multiple third openings 45 are equally spaced on the circumference of the feeding plate 44. A clamping structure is provided in each third opening 45. The clamping structure includes mounting blocks 46 located along the inner edge of the feeding tray 44 near the third opening 45. Each mounting block 46 has a third electric telescopic rod 47 mounted on the middle of its side closest to the axis of the feeding tray 44. An inner groove 50 is formed on the lower wall of the third opening 45. A fixed rod 51 is fixedly connected between the two ends of the inner groove 50. Moving blocks 52 are movably mounted on the fixed rod 51 near both ends. A pressing rod 53 is connected to the top of the moving block 52. Springs 54 are mounted on both ends of the fixed rod 51, with each end connected to the moving block 52 and the inner groove 50 wall, respectively. A clamping strip 55 extending through the inner groove 50 is connected to the moving block 52. Clamping blocks 56 are mounted on one side of the clamping strip 55 near both ends. A moving plate 48 is connected to one end of the output shaft of the third electric telescopic rod 47. Two pressing plates 49 are connected to the moving plate 48 near the middle, and the pressing plates 49 are pressed against the pressing rod 53. 3. When the building material to be built is placed into the third opening 45 on the feeding tray 44, the third electric telescopic rod 47 is activated to drive the moving plate 48 and the pressing plate 49 as a whole to move away from the axis of the feeding tray 44. Through the pressing plate 49 pressing the pressing rod 53, the two clamping bars 55 can be pushed to move towards each other, thereby driving the clamping block 56 to move towards the middle to clamp and fix the building material. When the starting motor 41 drives the feeding tray 44 to rotate, the clamped building material can be transported to the fixed frame 5 for inspection. After inspection, as the feeding tray 44 continues to rotate, the inspected building material can be transported to the position directly above the receiving frame 39. At this time, the third electric telescopic rod 47 is activated to release the corresponding building material, so that the inspected building material can fall from the corresponding second opening 38 into the receiving frame 39, realizing the automatic unloading function and improving the inspection efficiency.

[0019] The implementation principle of a building material testing device for construction is as follows: First, the building material to be tested is placed into the third opening 45 on the feeding tray 44. The third electric telescopic rod 47 is activated, driving the moving plate 48 and the pressing plate 49 to move away from the axis of the feeding tray 44. The pressing plate 49 presses the pressing rod 53, pushing the two clamping bars 55 to move towards each other, thereby driving the clamping block 56 to move towards the center to clamp and fix the building material. Then, the motor 41 is activated, driving the feeding tray 44 to rotate, conveying the clamped building material to the fixing frame 5. The first electric telescopic rod 6 is activated, driving the lifting block 7, guide rail plate 9, mounting frame 11 and pressure block 35 to move downward as a whole. During the downward movement, the top of the first insertion rod 12 slides from the first insertion slot 14 into the first guide slot 15. The pressure of the end of the first insertion rod 12 against the wall of the first guide slot 15 causes the moving sleeve 10 to move to the left on the guide rail plate 9, thereby causing the mounting frame 11 and pressure block 35 to move to the left as a whole. When the top of the first insertion rod 12 slides into the vertical section of the first guide slot 15, the moving sleeve 10 remains in a fixed position on the guide rail plate 9. As the lifting block 7 continues to move downward, it can cause the pressure block 35 to press against the building material. The pressure sensor 36 senses the pressure generated during the pressing and displays it on the display screen of the controller 37, thus realizing the detection of the building material's impact resistance performance and the detection of the impact resistance of the building material. After a certain position is detected, the first electric telescopic rod 6 drives the lifting block 7 to move upward, thereby moving the top of the first insertion rod 12 out of the vertical section of the first guide groove 15. The first insertion rod 12 moves vertically upward and presses against the groove wall of the second guide groove 16, causing the moving sleeve 10 to continue moving the pressure block 35 to the left on the guide rail plate 9. When the top of the first insertion rod 12 slides to the uppermost position in the second guide groove 16, the lifting block 7 moves to the highest position. Then, the first electric telescopic rod 6 drives the lifting block 7 and the first insertion rod 12 to move downward. The moving first insertion rod 12 presses against the lower groove wall of the corresponding first guide groove 15. As the first insertion rod 12 continues to move downward, the moving sleeve 10 continues to move to the left on the guide rail plate 9. In this way, the lifting block 7 drives the first... When one end of the insertion rod 12 slides in the corresponding first guide groove 15, it can drive the pressure block 35 to perform detection work on different positions on the building material, thereby improving the detection accuracy and making the operation more labor-saving and convenient. When the moving sleeve 10 moves to the leftmost position on the guide rail plate 9, the lifting block 7 is at the lowest position. The second electric telescopic rod 22 can be activated to drive the driving frame 24 to slide downward in the driving groove 26. Through the squeezing of the driving frame 24 against the groove wall of the driving groove 26, the through plate 25 is pushed to move on the mounting frame 11, thereby pulling the top end of the first insertion rod 12 out of the first guide groove 15 corresponding to the front of the horizontal plate 13. At this time, the driving frame 24 moves down half the height, and then the first electric telescopic rod 6 drives the lifting block 7 to move up to the highest position.The second electric telescopic rod 22 drives the driving frame 24 to continue moving downward in the driving groove 26. Through the compression of the groove wall by the driving frame 24, the through plate 25 continues to move on the mounting frame 11, thereby causing the top of the second insert rod 17 to insert into the second insertion groove 18 on the back of the horizontal plate 13. Then, the motor 41 drives the feeding disc 44 to rotate, fixing the next piece of building material to be tested at the bracket 5. As the lifting block 7 continues to move up and down, the top of the second insert rod 17 slides in the third guide groove 19 and the fourth guide groove 20, causing the pressure block 35 to move intermittently to the right, thus testing the compressive strength of various positions on the next piece of building material. Finally, the continued rotation of the feeding disc 44 transports the tested building material to the position directly above the receiving frame 39. At this time, the third electric telescopic rod 47 is activated to release the corresponding building material, allowing the tested building material to fall from the corresponding second opening 38 into the receiving frame 39, achieving automatic unloading and improving testing efficiency.

[0020] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
