[0002] A building material impact testing device is a device used to evaluate the performance of building materials. It mainly tests the impact resistance and toughness of materials by simulating impact forces. This type of device is commonly used for quality control and performance evaluation of building materials such as concrete, brick, and metal.

[0025] This specific embodiment is a building material impact testing device, the structural schematic diagram of which is shown below. Figures 1-7As shown, the mounting plate 1 is circular. Evenly distributed fixing plates 2 are fixedly connected to the side wall of the mounting plate 1. Gears 3 are symmetrically fixedly connected to one side of each fixing plate 2. A horizontal plate 4 is movably connected between two gears 3 on the same fixing plate 2. An electromagnet 5 is fixedly connected to the bottom of the horizontal plate 4, away from the mounting plate 1. An iron ball 6 is located at the bottom of the electromagnet 5.

A height adjustment mechanism is provided on the side wall of the horizontal plate 4. The mechanism includes a cylindrical rod 14 located below the mounting plate 1, with the top end of the cylindrical rod 14 penetrating through the mounting plate 1 and movably connected to it. A support plate 15 is located above the mounting plate 1, and the support plate 15 is L-shaped. A rotating fixing mechanism is provided between the top of the mounting plate 1 and the cylindrical rod 14. The top end of the cylindrical rod 14 is fixedly connected to the support plate 15. A square tube 16 is sleeved on the side wall of the support plate 15, and a base plate 22 is fixedly connected to the bottom of the square tube 16. A lifting mechanism is provided between the square tube 16 and one side of the support plate 15.

[0026] The electromagnet 5 in this technical solution is a commonly used device on the market. The basic principle of the electromagnet 5 is that when current passes through a wire, a magnetic field is generated around the wire. By winding the wire into a coil and energizing it, the strength of the magnetic field can be enhanced. Usually, the core material of the electromagnet 5 is iron or other magnetic materials, which can further enhance the magnetic field. When installing and using the electromagnet 5, the weight of the actual iron ball 6 needs to be considered to select an appropriate size of the electromagnet 5 to ensure performance and efficiency. In addition, the electromagnet 5 in this technical solution needs to be installed with a control power supply during use. By controlling the power supply to energize and de-energize the electromagnet 5, the function of attracting and releasing the iron ball 6 can be achieved.

[0027] like Figures 2-5 As shown, the height adjustment mechanism includes an installation opening 8 on the side wall of the horizontal plate 4. A square rod 9 is provided in the installation opening 8. Both ends of the square rod 9 extend to the outside of the installation opening 8. Arc-shaped plates 10 are symmetrically fixedly connected to the side of the square rod 9 opposite to the mounting plate 1. Evenly distributed toothed blocks 11 are fixedly connected to the side of the arc-shaped plates 10 opposite to the mounting plate 1. The toothed blocks 11 mesh with the gear 3. A first spring 12 is fixedly connected between the square rod 9 and the inner wall of one side of the installation opening 8.

[0028] The swing angle of the horizontal plate 4 can be adjusted by the height adjustment mechanism, which can adjust the height of the electromagnet 5 and the iron ball 6. By adjusting the height of the iron ball 6, the impact force on the building materials can be adjusted, making it more flexible to use.

[0029] like Figure 2 and Figure 6As shown, the rotating fixing mechanism includes a U-shaped plate 24 fixed to the top of the mounting plate 1, a pin 25 is provided above the mounting plate 1, the pin 25 is L-shaped, and the cylindrical rod 14 has evenly distributed pin grooves 26 on its side wall. One end of the pin 25 passes through the U-shaped plate 24 and extends into the pin groove 26. A stop block 28 is fixedly connected to the top of the mounting plate 1, and a second spring 27 is fixedly connected between the stop block 28 and the pin 25.

[0030] The rotating mechanism allows for readjustment of the impact position and angle of the iron ball 6 based on the existing impact angle, and the adjusted position can be fixed so that the mounting plate 1 does not rotate arbitrarily. This increases both the ease of use and the versatility of application.

[0031] like Figure 1 and Figure 7 As shown, the lifting mechanism includes a rectangular plate 17 fixed on the side wall of the support plate 15, a positioning plate 18 fixedly connected to one side of the square tube 16, a screw hole 20 opened on the top of the positioning plate 18, a screw rod 19 installed in the screw hole 20, the top end of the screw rod 19 passes through the rectangular plate 17 and is movably connected to the rectangular plate 17, and a knob 21 is fixedly connected to the top end of the screw rod 19.

[0032] The lifting mechanism allows the position of the iron ball 6 impacting the building material to be changed according to actual needs without affecting the impact force of the iron ball 6. This enables the iron ball 6 to impact different heights at the same angle during testing, effectively improving the accuracy of the test.

[0033] The horizontal plate 4 has a rectangular opening 23 at the top, which is connected to the inside of the first spring 12. A handle 13 is provided above the rectangular opening 23. The bottom end of the handle 13 passes through the rectangular opening 23 and is fixedly connected to the top of the square rod 9. The handle 13 can be used to pull the square rod 9 to compress the first spring 12. In addition, the cross-sections of the handle 13 and the square rod 9 are both rectangular. The square rod 9 matches the inner wall of the mounting opening 8, so that the square rod 9 will not rotate when it is pulled.

[0034] In addition, both the fixed plate 2 and the horizontal plate 4 are arranged in a ring array. The horizontal plate 4 arranged in a ring array makes the position distribution of the iron ball 6 more uniform, so as to adapt to the multi-faceted uniform building materials and to help adjust the position of the iron ball 6 to be impacted.

[0035] Working Principle: In use, this technical solution first requires the installation of a control power supply, which is linearly connected to multiple electromagnets 5. The power supply controls the energization and de-energization of the electromagnets 5. When an electromagnet 5 is energized, it generates magnetism. At this time, an iron ball 6 is placed below the electromagnet 5, and the magnetism of the electromagnet 5 attracts the iron ball 6, preventing it from falling. Next, the building material to be tested can be placed on the base plate 22 and moved directly below the mounting plate 1. To increase the impact force, the handle 13 can be used to pull the square rod 9, compressing the first spring 12 and disengaging the gear 11 from the gear 3. Then, the horizontal plate 4 can be adjusted to swing upwards or downwards. The higher the position of the iron ball 6, the greater its downward inertia, thus increasing the impact force. Conversely, the lower the position of the iron ball 6, the smaller its downward inertia and the smaller the impact force. After adjusting the height of the iron ball 6 to the desired height, the square rod 9 is released. Simultaneously, the first spring 12 pushes the square rod 9 towards the mounting plate 1, causing the gear 11 to... 1 meshes with gear 3, thus fixing the position of the adjusted horizontal plate 4. If it is necessary to adjust the impact position of multiple iron balls 6, the second spring 27 can be compressed by pulling the pin 25, causing the pin 25 to disengage from the pin groove 26. This allows the mounting plate 1 and the horizontal plate 4 to be rotated as a whole, thereby adjusting the impact angle of the iron balls 6. After adjustment, the pin 25 is released, and the rebound force of the second spring 27 pushes the pin 25 into the pin groove 26, thus fixing the position of the rotated mounting plate 1. If it is necessary to adjust the impact position of the iron balls 6, the screw 19 can be rotated by the knob 21, causing the support plate 15 and the mounting plate 1 to rise or fall as a whole, thereby adjusting the height at which the iron balls 6 impact the building materials. Next, impact testing can be carried out. First, the power supply can be controlled to simultaneously or individually de-energize the electromagnets 5. When the electromagnets 5 are de-energized, they will lose their magnetism, and the iron balls 6 will fall due to their own weight and swing towards the center to impact the building materials. By observing the appearance of the building materials after the impact, it can be determined whether the building materials are qualified.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
