DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 4 As shown, a building material impact strength test structure is used to perform strength testing on building materials such as tiles, wooden boards, and concrete blocks. The testing structure includes a support base 1, on which a clamping device for clamping building materials is provided, a top plate 7 is provided above the support base 1, and a hanging member 6 is provided between the top plate 7 and the support base 1. The top of the hanging member 6 passes through the top plate 7, and the hanging member 6 can move up and down relative to the top plate 7. The bottom of the hanging member 6 is connected to an impact block 2, which falls and impacts the building material on the support base 1 to test the strength of the building test;

[0027] The detection structure also includes a lifting horizontal plate 8, a driving motor 10 and a telescopic top rod. The lifting horizontal plate 8 is horizontally arranged above the top plate 7, and the lifting horizontal plate 8 is connected to the top of the hanging member 6. A sliding connection piece is vertically arranged on the top plate 7, and the lifting horizontal plate 8 is slidably connected to the sliding connection piece. The lifting horizontal plate 8 can move up and down through the sliding connection piece.

[0028] The driving motor 10 is installed at one end of the top plate 7 through a mounting seat, and the main shaft of the driving motor 10 is parallel to the top plate 7; it should be noted that the lifting horizontal plate 8 is located on one side of the main shaft of the driving motor 10 to prevent it from crossing over the main shaft of the driving motor 10;

[0029] The telescopic top rod is vertically connected to the main shaft of the driving motor 10. The telescopic top rod includes a connecting sleeve 11 and a sliding rod 13. The connecting sleeve 11 is connected to the main shaft of the driving motor 10. The connecting sleeve 11 is perpendicular to the main shaft of the driving motor 10. The sliding rod 13 slides and inserts in the connecting sleeve 11, and the end of the sliding rod 13 cooperates with the lifting horizontal plate 8. The end of the sliding rod 13 is connected to a pulley 14. A fixing bolt 12 is provided at one end of the connecting sleeve 11 close to the sliding rod 13. The fixing bolt 12 penetrates the side wall of the connecting sleeve 11, and the fixing bolt 12 is threadedly connected to the connecting sleeve 11.

[0030] When it is necessary to raise the impact block 2 and then fall and hit the building material, the drive motor 10 is started, so that the drive motor 10 drives the telescopic top rod to deflect counterclockwise, and the slide bar 13 in the telescopic top rod hits the lifting cross plate 8 when it rotates to the bottom of the lifting cross plate 8, and then pushes the lifting cross plate 8 to rise. In this process, the pulley 14 facilitates the relative sliding between the end of the slide bar 13 and the bottom end surface of the lifting cross plate 8, and the lifting cross plate 8 drives the impact block 2 to rise through the hanging piece 6. When the slide bar 13 rotates to a vertical position above the main shaft of the drive motor 10, the end of the slide bar 13 The part will be separated from the lifting horizontal plate 8, and the lifting horizontal plate 8 will lose its support and fall by gravity, so that the impact block 2 will fall and hit the building materials, and when it is necessary to adjust the falling height of the impact block 2, thereby adjusting the falling impact force, the sliding rod 13 is directly made to slide relative to the connecting sleeve 11, and the length of the telescopic top rod is adjusted. After the length is adjusted, the sliding rod 13 is tightened by the fixing bolt 12. Telescopic top rods of different lengths can push the lifting horizontal plate 8 to different heights, thereby making it easy for the impact block 2 to fall from different heights and hit the building materials with corresponding impact forces.

[0031] In some specific implementation schemes, the hanging member 6 is a connecting rope, which facilitates changing the length of the hanging member 6 by tying a knot.

[0032] In some specific embodiments, the sliding connection member includes a support rail 9, which is vertically fixedly connected to the upper side of the top plate 7, and the end of the lifting cross plate 8 away from the drive motor 10 is slidably connected to the support rail 9.

[0033] In some specific implementation schemes, a transparent glass tube 15 is connected between the top plate 7 and the supporting base 1. The transparent glass tube 15 is made of tempered glass. A switchable movable door is provided on the front side of the transparent glass tube 15. When conducting strength testing of building materials, observation can be made through the transparent glass tube 15. At the same time, the transparent glass tube 15 prevents ceramic tile-like building materials from producing flying fragments when hit, which could cause danger to people around.

[0034] In some specific embodiments, the clamping device includes a threaded sleeve 3, an adjusting screw 4 and a clamping plate 5. Two threaded sleeves 3 are provided and are respectively connected to the two ends of the support base 1. Two adjusting screws 4 are provided and respectively penetrate the corresponding threaded sleeves 3. The adjusting screw 4 is threadedly connected to the corresponding threaded sleeve 3. Two clamping plates 5 are provided and are respectively connected to the corresponding adjusting screws 4. When the building material is placed on the support base 1, the building material is placed between the clamping plates 5, and then the adjusting screws 4 on both sides are rotated to drive the two clamping plates 5 to move toward the middle to fix the building material.

[0035] In some specific implementation schemes, in order to facilitate the calculation of the impact force when the impact block 2 impacts the material, the impact block 2 is configured to include an upper impact body 18, a lower impact body 19 and a pressure sensor 16; the upper impact body 18 is connected to the hanging member 6, the pressure sensor 16 is hidden at the bottom of the upper impact body 18, and the detection end of the pressure sensor 16 is connected to the lower impact body 19, and a numerical display terminal 17 electrically connected to the pressure sensor 16 is provided on the top plate 7, and a calculation unit is provided in the numerical display terminal 17;

[0036] When the impact block 2 falls from the corresponding height and hits the material, the pressure sensor 16 detects the instantaneous force and displays it through the numerical display terminal 17, so that the operator can know how much impact force the impact block 2 can generate when falling from the corresponding height, which is convenient for experimental measurement. The specific calculation process of the impact force is as follows: the calculation unit calculates through the formula F=MV, where F is the impact force, M is the overall weight of the impact block 2, and V is the instantaneous speed of the impact block 2 when it hits the material. Since the impact block 2 falls freely, V=gt here, where g is the acceleration of gravity, and t is the falling time of the impact block 2. Since h=1 / 2gt 2 , where H is the falling distance of the impact block 2, that is, the falling height adjusted in each test, so the falling time t can be calculated, which makes it easier to calculate the instantaneous speed V and finally calculate the impact force F.

[0037] In order to facilitate those skilled in the art to easily understand the embodiments of the present solution, the working principle of the embodiments of the present solution is now described in combination with specific application scenarios:

[0038] First, place the building material to be tested for strength between the two clamping plates 5, then rotate the adjusting screws 4 on both sides to drive the two clamping plates 5 to move toward the middle to clamp the building material;

[0039] Then start the drive motor 10, the drive motor 10 drives the telescopic top rod to deflect counterclockwise, and the slide bar 13 in the telescopic top rod hits the lifting cross plate 8 when it rotates to the bottom of the lifting cross plate 8, and then pushes the lifting cross plate 8 to rise. In this process, the pulley 14 facilitates the relative sliding between the end of the slide bar 13 and the bottom end surface of the lifting cross plate 8, and the lifting cross plate 8 drives the impact block 2 to rise through the hanging member 6. When the slide bar 13 rotates to a vertical position above the main shaft of the drive motor 10, the end of the slide bar 13 separates from the lifting cross plate 8, and the lifting cross plate 8 is lifted. The lowering plate 8 loses its support and falls by gravity, so that the impact block 2 falls and hits the building materials. When it is necessary to adjust the falling height of the impact block 2 and thus adjust the falling impact force, the slide rod 13 is directly made to slide relative to the connecting sleeve 11 to adjust the length of the telescopic top rod. After the length is adjusted, the slide rod 13 is tightened by the fixing bolt 12. Telescopic top rods of different lengths can push the lifting plate 8 to different heights, thereby making it easier for the impact block 2 to fall from different heights and hit the building materials with corresponding impact forces.

[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
