DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4In an embodiment of the present utility model, a building material strength testing device includes a workbench 1. The top of the workbench 1 is provided with a fixing mechanism for fixing the building materials during testing. The fixing mechanism includes a motor 21, a support frame 22, a bidirectional screw 23 and an L-shaped plate 24. Two motors 21 are installed on one side of the workbench 1 by bolts. A movable groove 10 is symmetrically opened on the top of the workbench 1. Multiple groups of support frames 22 are slidably connected inside the movable groove 10. The output ends of the two motors 21 are fixedly connected to the bidirectional screw 23 through a rotating shaft. One end of the bidirectional screw 23 passes through the workbench 1 and the support frame 22 and is rotatably connected to the inner wall of the movable groove 10 through a bearing seat, and the support frame 22 is rotatably connected to the bidirectional screw 23 through a thread. The top of the support frame 22 extends to the top of the workbench 1 and is welded to the two ends of the bottom surface of the L-shaped plate 24 respectively.

[0023] A support plate 11 is provided between the L-shaped plates 24 and is at the same level as one end of the top surface thereof. A connecting rod 12 is welded to the middle part of the bottom surface of the support plate 11. The bottom end of the connecting rod 12 is connected to the top of the workbench 1 by screwing. The connecting rod 12 and the top of the workbench 1 are provided with a threaded connection, which can facilitate the disassembly and replacement of the connecting rod 12 according to the needs of use. The provided support plate 11 is used to provide auxiliary support for the building materials during the strength test, which can prevent the middle of the bottom of the building materials from being suspended, thereby reducing the phenomenon of building materials breaking.

[0024] When in use, the two motors 21 are controlled to start at the same time. When the output end of the motor 21 rotates, the bidirectional screw 23 rotates accordingly. Through the rotation of the bidirectional screw 23, the support frame 22 connected thereto moves closer to or away from each other in the movable groove 10. When the support frame 22 moves, the L-shaped plate 24 welded to the top thereof moves synchronously therewith, so that the L-shaped plate 24 can fix and clamp the side walls of building materials of different sizes, so that it will not easily move in position during strength testing.

[0025] The four corners of the top of the workbench 1 are welded with brackets 6, and the top ends of the brackets 6 are welded to the bottom of the mounting plate 7. Two hydraulic rods 8 are installed side by side on the bottom of the mounting plate 7 by bolts. The top surfaces of the movable ends of the two hydraulic rods 8 are provided with adjustment mechanisms for adjusting and detecting building materials of different sizes. The adjustment mechanism includes a U-shaped frame 31, an adjustment rod 32, an adjustment block 33 and a fixed frame 34. The top surfaces of the movable ends of the two hydraulic rods 8 are fixedly mounted on the top of the U-shaped frame 31, and the bottom end of the inner wall of the U-shaped frame 31 is rotatably connected to the adjustment rod 32. Both ends of the adjustment rod 32 extend to the outside of the U-shaped frame 31 and are connected to the side walls of the U-shaped frame 31 through a limit assembly. The surface of the adjustment rod 32 located inside the U-shaped frame 31 is welded with an adjustment block 33, and the side walls of the adjustment block 33 are welded with a fixed Frame 34, the inner wall of the end of the fixed frame 34 away from the adjusting block 33 is connected to one end of the pressure block 9 through a disassembly mechanism, and the limit assembly includes an adjusting plate 41, a limit rod 42 and a first spring 43. Both ends of the adjusting rod 32 extend to the outside of the U-shaped frame 31 and are welded with an adjusting plate 41. A through hole 44 is provided on the side wall of the adjusting plate 41. Multiple groups of limit grooves 45 with the same aperture as the through hole 44 are provided in a circumferential direction on both sides of the U-shaped frame 31. One end of the limit rod 42 passes through the through hole 44 and extends to the inside of the limit groove 45, and the limit rod 42 is slidably connected to the through hole 44 and the limit groove 45. A baffle 46 is welded to the end of the limit rod 42 located on the outside of the adjusting plate 41, and a first spring 43 arranged on the surface of the limit rod 42 is fixedly installed between the baffle 46 and the side wall of the adjusting plate 41.

[0026] There are four pressing blocks 9 of different sizes. The pressing blocks 9 can be installed as frequently used ones, which can reduce the frequency of the operator manually disassembling and installing the pressing blocks 9 back and forth during inspection, thereby reducing work intensity and improving work efficiency.

[0027] When in use, the baffle 46 is pulled to move the limit rod 42 toward the side away from the limit groove 45, and the first spring 43 is stretched and deformed. When the limit rod 42 is out of the limit groove 45, the rotating adjustment plate 41 causes the adjustment block 33 to rotate accordingly through the adjustment rod 32. When the adjustment block 33 rotates, the pressure block 9 is driven to rotate synchronously therewith through the disassembly mechanism. When the pressure block 9 is adjusted to match the size of the building material to be inspected, the force applied to the baffle 46 is released. At this time, the first spring 43 is reset and deformed, causing the limit rod 42 to be reinserted into the corresponding position through the through hole 44. The limiting groove 45 of the U-shaped frame 31 allows the adjusting rod 32 to be stably fixed in the U-shaped frame 31, and can prevent the adjusting rod 32 from driving the pressure block 9 to rotate through the adjusting block 33, thereby affecting the subsequent normal operation. After the pressure block 9 is adjusted, the movable ends of the two hydraulic rods 8 are controlled to extend at the same time. At this time, the U-shaped frame 31 moves downward, so that the pressure block 9 continues to approach the building material and apply pressure to test the strength of the building material. There is no need to remove the original pressure block 9 according to the needs of use and then install one that is compatible with the building material to be tested. This is convenient for the operator to use and improves the accuracy of the experimental data.

[0028] The disassembly mechanism includes a second spring 51 and a limit block 52. One end of the pressure block 9 is slidably inserted into the inner wall of the end of the fixed frame 34 away from the adjusting block 33. Rectangular grooves 13 are symmetrically provided on both sides of one end of the pressure block 9. Two second springs 51 are welded to the inner wall of the rectangular groove 13. The other ends of the two second springs 51 are welded to the end of the limit block 52. A through groove 14 corresponding to the rectangular groove 13 is provided on the side wall of the fixed frame 34. The end of the limit block 52 away from the second spring 51 passes through the through groove 14 and extends to the outside of the fixed frame 34, and the limit block 52 is slidably connected to the rectangular groove 13 and the through groove 14.

[0029] When the pressure block 9 is ready to be removed, hold the pressure block 9 and press the symmetrical limit block 52 at the same time, so that the second spring 51 is compressed and deformed. When the limit block 52 is continuously applied with force, it is disengaged from the through groove 14 and enters the rectangular groove 13. Then, the pressure block 9 is pulled to slide one end of the pressure block out from the inner wall of the end of the fixed frame 34. When the new pressure block 9 is ready to be installed, the limit block 52 is still applied with extrusion force to make it in the rectangular groove 13, and one end of the pressure block 9 is inserted into the corresponding inner wall of the end of the fixed frame 34. The positioning block 52 enters the inner wall of the end of the fixed frame 34 as one end of the pressure block 9, and the inner wall of the end of the fixed frame 34 still applies an extrusion force to the positioning block 52. When the positioning block 52 is driven to the through groove 14 by the pressure block 9, the second spring 51 undergoes elastic reset deformation, thereby driving the positioning block 52 to pass through the through groove 14 and extend to the outside of the fixed frame 34, thereby limiting and fixing the pressure block 9 and the fixed frame 34, so that the pressure block 9 will not fall out of the fixed frame 34. The operation is simple, and the pressure block 9 is easy to install and remove quickly.

[0030] Working principle: When using the building material strength testing device, first place the building material on the support plate 11, then start the motor 21 to control the fixing mechanism to operate, so that the L-shaped plate 24 can stably fix and clamp the building material, then pull the baffle 46 to make the limit rod 42 release the position restriction of the adjustment plate 41, and then rotate the adjustment plate 41 through the adjustment rod 32 and the adjustment block 33 so that the disassembly mechanism drives the pressure block 9 to rotate synchronously. When the pressure block 9 is adjusted to match the building material to be tested, release the force applied to the baffle 46. At this time, the first spring 43 is reset and deformed, so that the limit The rod 42 is reinserted into the corresponding limit groove 45, thereby limiting the position of the adjustment plate 41, so that the pressure block 9 can be in a stable working state, and then the movable end of the hydraulic rod 8 is controlled to extend, so that the pressure block 9 moves downward, thereby applying pressure to the building material and detecting the strength of the building material. When the pressure block 9 needs to be disassembled for maintenance or replacement, hold the pressure block 9 and press the symmetrical limit block 52 at the same time, so that the limit block 52 disengages from the through groove 14 and enters the rectangular groove 13. Then, pull the pressure block 9 to slide one end of it out from the inner wall of the end of the fixed frame 34. The operation is simple and convenient to use.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
