Description

Technical Field

[0002] As a new type of building material, insulation board has good mechanical properties and durability. The application of insulation board can effectively reduce the heat loss of buildings. Compared with traditional building materials such as bricks and concrete, insulation board has the advantages of light weight, high efficiency and environmental protection.

[0003] During the quality inspection of the insulation board production, it is necessary to test the compressive strength of the insulation board samples. The current common insulation board compressive strength testing methods are usually divided into extrusion tests and drop ball impact tests. However, during the drop ball impact test, each time the drop ball impacts the insulation board, the staff needs to manually pick up the drop ball and reset the drop ball before the next drop test. The insulation board needs to be tested multiple times during the entire test process, so the staff needs to frequently pick up the drop ball, which increases the work intensity of the staff. Therefore, this application specifically proposes an insulation board strength testing device that does not require manual resetting of the drop ball. Utility Model Content

[0028] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0029] See also Figure 1-Figure 5 .

[0030] The utility model discloses a thermal insulation board strength testing device, comprising:

[0031] The test stand 1 comprises a base 11, a top plate 12 is arranged above the base 11, a support rod 13 is arranged between the base 11 and the top plate 12, and the support rod 13 connects the base 11 and the top plate 12;

[0032] A placing component 2, arranged on a base 11, for placing a heat preservation board 7 to be tested;

[0033] The sleeve 3 is arranged between the base 11 and the top plate 12, one end of the sleeve 3 is connected to the bottom of the top plate 12, and the other end of the sleeve 3 is close to the upper surface of the placement component 2. A falling ball 6 with a radius smaller than the radius of the sleeve 3 is arranged in the sleeve 3, and when the insulation board 7 is placed on the placement component 2, the distance between the sleeve 3 and the insulation board 7 is smaller than the diameter of the falling ball 6. The sleeve 3 is used to restrict the deflection range caused by the reaction force of the falling ball 6 hitting the insulation board 7 after the falling ball 6 falls;

[0034] The recovery component 4 includes a telescopic rod 41 vertically arranged on the top plate 12, the telescopic end of the telescopic rod 41 passes through the top plate 12 and is inserted into the sleeve 3, and an electromagnet 42 for adsorbing the falling ball 6 is provided on the telescopic end of the telescopic rod 41. When preparing for the experiment, the telescopic end of the telescopic rod 41 contracts and drives the falling ball 6 to rise to a specified height in the sleeve 3 through the electromagnet 42. When recovering the falling ball 6, the telescopic end of the telescopic rod 41 extends and adsorbs the falling ball 6 through the electromagnet 42, driving the falling ball 6 to reset.

[0035] In the specific implementation, after the staff places the insulation board 7 to be tested on the placement component 2, the electromagnet 42 is energized and absorbs the falling ball 6, and the telescopic rod 41 is contracted to drive the falling ball 6 to rise to the height required for the experiment in the sleeve 3. When the telescopic end of the telescopic rod 41 is contracted to the specified position, the electromagnet 42 is powered off, and the magnetic force between the electromagnet 42 and the falling ball 6 is lost. The falling ball 6 naturally falls under the influence of gravity and hits the surface of the insulation board 7. The gap between the sleeve 3 and the placement component 2 constrains the falling ball 6 in the sleeve 3. When the falling ball 6 completes a test, the telescopic end of the telescopic rod 41 extends until the electromagnet 42 contacts the falling ball 6. At this time, the electromagnet 42 is energized to absorb the falling ball 6 and drives the falling ball 6 to rise and reset through the contraction of the telescopic rod 41, waiting for the next experiment.

[0036] According to the utility model, after the falling ball 6 performs an impact test on the insulation board 7, the falling ball 6 is recovered by the recovery component 4 and driven to rise to the required height for the experiment, waiting for the next experiment. The sleeve 3 limits the displacement range caused by the reaction force after the impact test of the falling ball 6 without interfering with the free fall of the falling ball 6, so that the electromagnet 42 can recover the falling ball 6 more accurately. The whole process does not require manual recovery of the falling ball 6, thereby reducing the workload of the staff.

[0037] Preferably, the telescopic rod 41 can be an electric push rod in the prior art.

[0038] In one embodiment, first abutment blocks 411 are respectively provided on both sides of the telescopic end of the telescopic rod 41, and an end of the first abutment block 411 close to the placement component 2 is provided with an inclined surface, and two notches 31 are vertically provided on the sleeve 3, and one end of the first abutment block 411 passes through the notches 31 and can move up and down in the notches 31, and the sleeve 3 is further provided with a limit block 32 at the top position corresponding to the notch 31, and the limit block 32 is C-shaped, and a make way groove is provided in the middle to make way for the first abutment block 411;

[0039] A linkage component 5 is provided on the end of the sleeve 3 close to the placement component 2, and the linkage component 5 includes two tilting rods 51 vertically arranged at the positions corresponding to the notches 31, and the middle part of the tilting rod 51 is rotatably arranged on the side wall of the sleeve 3, and the end of the tilting rod 51 away from the placement component 2 is rotatably provided with a second abutment block 52, and one end of the second abutment block 52 is slidably inserted in the corresponding limit block 32, and the end of the second abutment block 52 away from the tilting rod 51 faces the sleeve 3 and has an inclined surface at the end, and a torsion spring (not shown in the figure) is provided on the rotation joint of the tilting rod 51. The spring drives the second abutment block 52 to move toward the side wall of the sleeve 3. A connecting block 53 is provided at one end of the tilting rod 51 away from the second abutment block 52. A cleaning member 54 is provided at the other end of the connecting block 53. When the telescopic end of the telescopic rod 41 is extended, the first abutment block 411 slides vertically downward in the slot 31 and squeezes the second abutment block 52. The second abutment block 52 slides in the limit block 32 in the direction away from the center of the sleeve 3 and drives the connecting block 53 to move toward the center of the sleeve 3 through the tilting rod 51, thereby cleaning the fallen ball 6 adsorbed on the electromagnet 42.

[0040] When the first abutment block 411 leaves the second abutment block 52, the torsion spring loses its constraint and drives the second abutment block 52 and the connecting block 53 to be reset through the corresponding tilting rod 51.

[0041] In one embodiment, a storage cavity 33 is provided on the sleeve 3, and the storage cavity 33 is provided below the notch 31 and communicates with the interior of the sleeve 3;

[0042] The cleaning component 54 includes a brush 541 connected to one end of the connecting block 53 away from the tilting rod 51. The brush 541 is slidably arranged in the storage chamber 33 along the center direction of the sleeve 3. An elastic unit 542 is provided between the brush 541 and the storage chamber 33. When the connecting block 53 moves toward the center direction of the sleeve 3, the connecting block 53 drives the brush 541 to slide toward the center direction of the sleeve 3, and the elastic unit 542 is stretched. When the connecting block 53 loses the force of the tilting rod 51, the elastic unit 542 resets and drives the brush 541 to slide away from the center direction of the sleeve 3.

[0043] With this design, when the first abutment block 411 abuts and pushes the second abutment block 52, the tilting rod 51 drives the brush 541 to slide toward the center of the sleeve 3 through the connecting block 53, so that the cleaning surface of the brush 541 extends into the sleeve 3. As the recovery component 4 recovers the falling ball 6, the telescopic end of the telescopic rod 41 contracts upward, and the falling ball 6 rises with the telescopic rod 41. At this time, the second abutment block 52 is still abutted by the first abutment block 411, and the falling ball 6 contacts the cleaning surface of the brush 541 during the rising process, thereby completing the cleaning until the first abutment block 411 no longer contacts the second abutment block 52. At this time, the connecting block 53 loses its force on the brush 541, and the elastic unit 542 resets and drives the brush 541 to slide away from the center of the sleeve 3 into the storage chamber 33.

[0044] Preferably, the elastic unit 542 can be a spring in the prior art.

[0045] It should be noted that the distance between the end of the slot 31 close to the base 11 and the second abutment block 52 is longer than the distance between the brush 541 and the fallen ball 6 to be recovered, thereby ensuring that when the electromagnet 42 drives the fallen ball 6 to rise and contact the brush 541, the first abutment block 411 and the second abutment block 52 are still abutted against each other, avoiding the cleaning component 54 from resetting at this time.

[0046] In one embodiment, the base 11 is provided with a first slide groove 111;

[0047] The placement component 2 includes a moving platform 21 slidably arranged in a first slide groove 111, a first screw 22 is rotatably arranged in the first slide groove 111, one end of the first screw 22 passes through the moving platform 21 and extends out of the base 11, and a power unit 23 is connected to the extended end of the first screw 22. When the power unit 23 rotates, the first screw 22 drives the moving platform 21 to slide in the first slide groove 111 toward or away from the support rod 13. An adjusting component 24 is also provided on the moving platform 21 for placing the insulation board 7.

[0048] With this design, when it is necessary to conduct experiments on multiple hitting points of the insulation board 7, the power unit 23 can be controlled to drive the first screw 22 to rotate, so that the mobile platform 21 slides in the first slide groove 111 toward or away from the support rod 13, thereby changing the hitting point of the falling ball 6 on the insulation board 7.

[0049] Preferably, the power unit 23 can adopt a motor in the prior art.

[0050] It should be noted that when the impact point of the heat preservation plate 7 is difficult to be positioned by the moving direction of the moving platform 21 , the placement direction of the heat preservation plate 7 on the placement component 2 can be adjusted.

[0051] In one embodiment, the mobile platform 21 is provided with a second slide slot 211;

[0052] The adjusting member 24 includes two oppositely arranged support frames 241 slidably arranged in the second slide groove 211, a second lead screw 242 is rotatably arranged in the second slide groove 211, and one end of the second lead screw 242 passes through each support frame 241 and extends out of the movable platform 21, a rotating handle 243 is provided at the extended end of the second lead screw 242, and two sections of threads in opposite directions are opened on the second lead screw 242, and each support frame 241 is screwed on the corresponding thread. When the second lead screw 242 rotates, the two opposite support frames 241 approach or move away from each other as the second lead screw 242 rotates.

[0053] With such a design, when the insulation board 7 is relatively large, the relative distance between the two support frames 241 is enlarged by rotating the second screw 242, so that the insulation board 7 can be smoothly placed on the support frame 241. When the insulation board 7 is relatively small, the relative distance between the two support frames 241 is reduced by reversing the second screw 242, so that the support frame 241 can adapt to insulation boards 7 of various sizes.

[0054] In one embodiment, the sleeve 3 is a transparent cylinder, and a scale for marking the height is provided on the surface of the sleeve 3. With this design, when the recovery component 4 recovers the fallen ball 6, the staff can know the position height of the fallen ball 6 in real time through the scale on the sleeve 3.

[0055] It should be noted that the sleeve 3 can be made of transparent materials such as tempered glass, polypropylene, and acrylic.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
