Description

Technical Field

[0001] This utility model relates to the field of board testing technology, and in particular to a testing mechanism for insulation boards. Background Technology

[0002] Insulation boards are rigid foam plastic boards made from polystyrene resin as the main raw material, along with other raw materials, auxiliary materials, and polymers. The mixture is heated and mixed while a catalyst is injected, and then extruded and molded. Insulation boards have moisture-proof and waterproof properties, allowing for a reduction in the thickness of the building's external envelope, thereby increasing usable indoor space. They can be used for building insulation. As an external envelope material, insulation boards must withstand impacts from external objects (such as tools and pedestrians). Impact testing assesses their resistance to breakage, ensuring that accidental collisions will not cause structural damage or safety hazards during long-term use.

[0003] The most common method for testing the impact resistance of insulation boards is to use an iron ball to strike them. This method typically involves adjusting the height of the iron ball to simulate impacts of varying intensities on the insulation board. However, this method can only simulate a very limited range of impacts, and it is difficult for workers with limited strength to lift the ball to a high position. As a result, the data range for the impact resistance test of the insulation board is small and cannot meet the testing requirements. Utility Model Content

[0004] The purpose of this application is to provide a testing mechanism for insulation boards, in order to solve the problem mentioned in the background art that when simulating impacts of different intensities on insulation boards by adjusting the height of an iron ball, the range that can be simulated is very limited, and it is difficult for workers with less strength to lift the ball to a high position, resulting in a small data range for the impact resistance test of insulation boards that cannot meet the testing requirements.

[0005] To achieve the above objectives, this application provides the following technical solution: a testing mechanism for insulation boards, comprising a base and a hollow steel ball. A lifting assembly and two sand storage boxes are installed on the upper part of the base. The two sand storage boxes are located on the front and rear sides of the lifting assembly, and the interior of the sand storage boxes is filled with lead sand. A carrier plate is installed on the lifting assembly, and the lifting assembly is used to adjust the height of the carrier plate in the longitudinal direction. An electromagnet is installed on the carrier plate. An iron column is fixed to the top of the outer side of the hollow steel ball. When the electromagnet is energized, it can magnetically attract the iron column. Two feeding pipes are fixedly connected to the hollow steel ball. The two feeding pipes are symmetrically distributed about the iron column, and a sealing cap is connected to the external thread of the top of the feeding pipe. A counterweight is fixed to the bottom of the inner side of the hollow steel ball.

[0006] Furthermore, the lifting assembly includes a rectangular frame plate, which is fixedly mounted on a base. A lead screw is rotatably connected between the upper and lower inner walls of the rectangular frame plate via bearings. A lead screw nut is mounted on the lead screw, and a slider is fixed on the lead screw nut. The slider slides against the inner wall of the rectangular frame plate. A carrier plate is fixedly mounted on the right side of the slider. A drive motor is mounted on the top of the rectangular frame plate, and the lead screw is driven by the drive motor.

[0007] Furthermore, two guide rods are fixed between the upper and lower inner walls of the rectangular frame plate, and the slider is slidably sleeved on the outside of the two guide rods.

[0008] Furthermore, a fence frame is fixed to the right side of the rectangular frame plate, and the fence frame is located directly below the electromagnet.

[0009] Furthermore, a cushioning pad is fixed to the inner side of the fence frame.

[0010] Furthermore, two fixing plates are fixed on the base, with the two fixing plates located on the front and rear sides of the fence frame respectively. A stud is vertically inserted into the fixing plate, and the fixing plate is threadedly connected to the stud. A knob is fixed to the top of the stud, and a pressure plate is rotatably connected to the bottom of the stud through a bearing. The pressure plate is located above the base.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, the height of the carrier plate and the electromagnet is adjusted by using a lifting component. After the electromagnet is energized, it can magnetically hold the iron column, so that the hollow steel ball can rise and fall with the electromagnet in the longitudinal direction. This adjusts the height of the hollow steel ball, thereby changing the impact force of the hollow steel ball on the insulation board. After unscrewing the sealing cap, lead sand can be filled into the hollow steel ball along the feeding pipe to increase the weight of the hollow steel ball. This allows the hollow steel ball to further increase the impact force on the insulation board within a limited lifting range, resulting in a wider range of impact resistance test data for the insulation board, which can better meet the testing requirements. After each impact test, the electromagnet can be adjusted to lower and then raise, saving the physical exertion of the staff in lifting the iron column.

[0013] 2. In this utility model, the fence frame is used to block the falling hollow steel balls inside itself, preventing the hollow steel balls from injuring the staff. The buffer pad is used to buffer the impact of the hollow steel balls on the fence frame. After the insulation board is placed on the base, the two knobs can be turned to make the knobs drive the stud to rotate. The stud pushes the pressure plate down, so that the pressure plate can firmly clamp the insulation board placed on the base, preventing the insulation board from shifting during impact testing.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: Reference Figure 1-5 The invention relates to a testing mechanism for an insulation board, comprising a base 1 and a hollow steel ball 5. A lifting assembly and two sand storage boxes 2 are installed on the upper part of the base 1. The two sand storage boxes 2 are located on the front and rear sides of the lifting assembly, and the sand storage boxes 2 are filled with lead sand. A carrier plate 3 is installed on the lifting assembly, and the lifting assembly is used to adjust the height of the carrier plate 3 in the longitudinal direction. An electromagnet 4 is installed on the carrier plate 3. An iron column 6 is fixed to the top of the outer side of the hollow steel ball 5. When the electromagnet 4 is energized, it can magnetically attract the iron column 6. Two feeding pipes 7 are fixedly connected to the hollow steel ball 5. The two feeding pipes 7 are symmetrically distributed about the iron column 6, and a sealing cap 8 is connected to the external thread of the top of the feeding pipe 7. A counterweight 9 is fixed to the bottom of the inner side of the hollow steel ball 5. The counterweight 9 is used to increase the weight of the hollow steel ball 5 and to make the hollow steel ball 5 hit the insulation board better with the counterweight 9 as the base when it falls.

[0023] The height of the carrier plate 3 and the electromagnet 4 is adjusted using the lifting component. When the electromagnet 4 is energized, it can magnetically hold the iron column 6, allowing the hollow steel ball 5 to rise and fall longitudinally along with the electromagnet 4. This adjusts the height of the hollow steel ball 5, thereby changing the impact force of the hollow steel ball 5 on the insulation board. After unscrewing the sealing cap 8, lead sand can be filled into the hollow steel ball 5 along the feeding pipe 7 to increase the weight of the hollow steel ball 5. This allows the hollow steel ball 5 to further increase the impact force on the insulation board within a limited lifting range, resulting in a wider range of impact resistance test data for the insulation board, which can better meet the testing requirements. After each impact test, the electromagnet 4 can be adjusted to lower and then raise the iron column 6, saving the physical exertion of the staff in lifting the iron column 6.

[0024] The lifting assembly includes a rectangular frame plate 10, which is fixedly installed on the base 1. A lead screw 11 is rotatably connected between the upper and lower inner walls of the rectangular frame plate 10 via bearings. A lead screw nut is installed on the lead screw 11, and a slider 12 is fixed on the lead screw nut. The slider 12 slides with the inner wall of the rectangular frame plate 10. A carrier plate 3 is fixedly installed on the right side of the slider 12. A drive motor 13 is installed on the top of the rectangular frame plate 10. The lead screw 11 is driven by the drive motor 13. Two guide rods 14 are fixed between the upper and lower inner walls of the rectangular frame plate 10, and the slider 12 is slidably sleeved on the outside of the two guide rods 14.

[0025] The drive motor 13 drives the lead screw 11 to rotate. The lead screw 11 drives the lead screw nut and slider 12 to move longitudinally in a lead screw transmission manner, thereby driving the carrier plate 3 and the electromagnet 4 on it to adjust the height in the longitudinal direction. The two guide rods 14 are used to support the slider 12 and share the force of the lead screw 11.

[0026] The rectangular frame 10 has a fence frame 15 fixed on its right side. The fence frame 15 is located directly below the electromagnet 4. A buffer pad 16 is fixed on the inside of the fence frame 15. The fence frame 15 is used to block the falling hollow steel ball 5 inside itself to prevent the hollow steel ball 5 from injuring the staff. The buffer pad 16 is used to buffer the impact of the hollow steel ball 5 on the fence frame 15.

[0027] Two fixing plates 17 are fixed on the base 1. The two fixing plates 17 are located on the front and rear sides of the fence frame 15 respectively. A stud 18 is vertically inserted into the fixing plate 17. The fixing plate 17 and the stud 18 are threadedly connected. A knob 19 is fixed at the top of the stud 18. A pressure plate 20 is rotatably connected to the bottom of the stud 18 through a bearing. The pressure plate 20 is located above the base 1.

[0028] After placing the insulation board on the base 1, you can turn the two knobs 19 to make the knobs 19 drive the stud 18 to rotate. The stud 18 pushes the pressure plate 20 down, so that the pressure plate 20 can firmly clamp the insulation board placed on the base 1 and prevent the insulation board from shifting during the impact test.

[0029] Working principle of this utility model:

[0030] The lead sand is temporarily placed inside the sand storage box 2 to await use. The drive motor 13 is activated to drive the lead screw 11 to rotate, causing the lead screw 11 to pull the slider 12, along with the carrier plate 3 and electromagnet 4, downwards. The iron column 6 at the top of the hollow steel ball 5 is pressed tightly against the bottom of the electromagnet 4. The electromagnet 4 is energized, causing it to magnetically attract the iron column 6. Then, the drive motor 13 is activated to drive the lead screw 11 to pull the electromagnet 4 and the hollow steel ball 5 upwards, raising the hollow steel ball 5 to the designated height. The insulation board to be tested is removed and cut into several pieces of appropriate size. One piece is placed flat on the base 1. Then, the knob 19 is turned to rotate the stud 18. The top-push pressure plate 20 moves down, clamping the insulation board placed on the base 1. Then, the electromagnet 4 is de-energized, so that the electromagnet 4 is no longer magnetically attracted to the iron column 6. The hollow steel ball 5 falls under its own weight, impacting the insulation board. The fence frame 15 can prevent the hollow steel ball 5 from detaching from the fence frame 15. Then, the drive motor 13 drives the lead screw 11 to move the electromagnet 4 down again, so that the iron column 6 is attracted by the energized electromagnet 4 again and lifted to a higher position. The impacted insulation board is removed and replaced with a new insulation board. The impact resistance test of the insulation board continues until the electromagnet 4 lifts the hollow steel ball 5 to the highest position that the lifting component can lift.

[0031] In subsequent testing, to broaden the range of data for the insulation board testing, after each hollow steel ball 5 is lifted to its highest point, the sealing cap 8 can be unscrewed, and lead sand from the sand storage box 2 can be added in batches to the interior of the hollow steel ball 5 using a bucket to increase the counterweight of the hollow steel ball 5, thereby causing a stronger impact on the insulation board. Finally, the insulation boards that have been impacted are labeled and the depth of the dents caused by the impact of the hollow steel ball 5 is measured. Relevant data conclusions are then obtained through calculation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
