Description

Technical Field

[0001] This utility model relates to the field of insulation board testing technology, specifically a testing device for insulation board production. Background Technology

[0002] Insulation boards, as a new type of building material, possess excellent mechanical properties and durability. Their application effectively reduces heat loss from buildings, and compared to traditional building materials such as bricks and concrete, they offer advantages such as being lightweight, efficient, and environmentally friendly. During the quality inspection process of insulation board production, samples need to be tested for compressive strength. Common methods for testing the compressive strength of insulation boards include the drop ball impact test.

[0003] In the prior art, such as the insulation board strength testing device described in Chinese Patent No. CN219084582U, there is a base, an insulation board support, a support column, a support plate, a T-shaped plate, a second support plate, and a hydraulic cylinder mechanism. The insulation board support is installed above the base, and the support column connects the base to the support plate. A lead screw is installed between the support plate and the base, and the lead screw and support column are respectively connected to the T-shaped plate. A motor and a housing are installed on the support plate, and the motor's power shaft is connected to the lead screw. The hydraulic cylinder mechanism, the ball-dropping impact mechanism, and the motor controller are located inside the housing. One end of the vertical plate of the T-shaped plate is connected to the second support plate, and the hydraulic cylinder mechanism and the ball-dropping impact mechanism are installed at both ends of the second support plate. The insulation board is placed on the insulation board support. After the impact test, the ball can be automatically retrieved, avoiding the inconvenience of manual retrieval by the operator, making the whole device more efficient, flexible, and convenient.

[0004] While the aforementioned patent can perform strength tests on insulation boards, it still has some problems. After the ball is dropped and impacted, it may bounce uncontrollably, potentially causing injury to personnel. Additionally, it cannot impact the insulation board from different angles, which may affect the test results. Therefore, this utility model provides a testing device for insulation board production. Utility Model Content

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a testing device for the production of insulation boards, comprising a base plate, a buffer frame fixedly installed on the top of the base plate, and a rotating placement component and a protective component respectively provided on the top of the base plate;

[0007] The rotating placement assembly includes a bracket, and a placement frame is rotatably mounted on the inner wall of the bracket via a rotating shaft. A placement groove is provided at the top of the placement frame. The rotating shaft on one side of the outer wall of the placement frame passes through the outer wall of the bracket and is fixedly mounted with a worm gear. A worm is meshed on the outer wall of the worm gear.

[0008] The protective component includes a protective cylinder, on the outer wall of which an installation ring is fixedly installed. A set of sliding rods slides evenly through the outer wall of the installation ring. An arc-shaped protective plate is fixedly installed at the bottom end of the sliding rods, and a spring is sleeved on the outer wall of the sliding rods.

[0009] Preferably, the bracket is fixedly installed on the top of the base plate, and two mounting plates are fixedly installed on one side of the outer wall of the bracket. The worm gear is rotatably installed between the opposite sides of the two mounting plates, and one end of the outer wall of the worm gear passes through the outer wall of the mounting plate and is fixedly installed with a rotating plate.

[0010] Preferably, two L-shaped plates are fixedly installed at the top of the placement frame. A threaded rod is threaded through the top of the L-shaped plate, and a pressure plate is rotatably installed at the bottom of the threaded rod. Two limiting rods slide through the top of the L-shaped plate, and the bottom ends of the two limiting rods are fixedly connected to the pressure plate. A rubber pad is fixedly installed at the bottom of the pressure plate.

[0011] Preferably, one end of the spring is fixedly connected to the mounting ring, the other end of the spring is fixedly connected to the arc-shaped protective plate, an electric push rod is fixedly installed at the top of the base plate, a connecting plate is fixedly installed at the output end of the electric push rod, and one end of the outer wall of the connecting plate is fixedly connected to the protective cylinder.

[0012] Preferably, an electric slide rail is fixedly installed at the top of the base plate, a movable slide plate is provided at the output end of the electric slide rail, an electromagnet is fixedly installed at the bottom end of the movable slide plate, and a ball is provided on the inner wall of the electromagnet.

[0013] Preferably, the sphere is positioned directly above the protective cylinder, and the diameter of the sphere is smaller than the inner wall diameter of the protective cylinder.

[0014] Beneficial effects

[0015] This invention provides a testing device for the production of insulation boards. Compared with the prior art, it has the following advantages:

[0016] (1) The testing device for the production of insulation board is equipped with a protective cylinder and an arc-shaped protective plate. Before the ball hits the insulation board, the arc-shaped protective plate can be attached to the surface of the insulation board by an electric push rod. If the insulation board has different angles, due to the multiple arc-shaped protective plates and springs, when the arc-shaped protective plate moves downward, its own elastic deformation can make the arc-shaped protective plate better attached to the surface of the insulation board, thus adapting to insulation boards with different angles. If the ball bounces after hitting the insulation board, it will be restricted from bouncing because it is inside the protective cylinder and the arc-shaped protective plate, thereby reducing the probability of the ball causing injury to personnel due to bouncing.

[0017] (2) When the insulation board needs to be tested, the insulation board is first placed on the placement slot on the placement frame. By rotating the threaded rod, the pressure plate at the bottom of the threaded rod can be moved up and down to fix the insulation board placed in the placement slot. The limit rod plays a guiding role to prevent the pressure plate from rotating. The rubber pad can increase the friction with the insulation board and prevent the insulation board from moving during the test. When the insulation board needs to be tested from different angles, the rotating plate is rotated to drive the worm gear to rotate. Since the worm gear meshes with the worm wheel, it drives the worm wheel to rotate, so that the placement frame rotates around the rotating axis in the bracket. The rotating placement component allows the insulation board to be adjusted to different tilt angles. Combined with the impact of the falling ball, it can simulate the impact force from different directions that the insulation board may be subjected to in the actual building scenario. Compared with the traditional device that can only be tested from a single vertical direction, this device can more comprehensively detect the compressive strength of the insulation board under various stress angles. The test results are more in line with the actual use situation and are conducive to more accurate evaluation of the quality of the insulation board. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-5 The first embodiment is shown: a testing device for the production of insulation board, including a base plate 1, a buffer frame 8 fixedly installed on the top of the base plate 1, and a buffer object such as sand can be placed in the buffer frame 8. When the ball 6 penetrates the insulation board, it can enter the buffer frame 8. The buffer object can absorb the kinetic energy of the ball 6 falling, thereby preventing the ball 6 from rebounding. The top of the base plate 1 is respectively provided with a rotating placement component 2 and a protective component 7.

[0027] The rotating placement assembly 2 includes a bracket 21. A placement frame 22 is rotatably mounted on the inner wall of the bracket 21 via a rotating shaft. A placement groove 23 is provided at the top of the placement frame 22. A rotating shaft on one side of the outer wall of the placement frame 22 passes through the outer wall of the bracket 21 and is fixedly mounted with a worm gear 24. A worm 25 is meshed on the outer wall of the worm gear 24.

[0028] The protective component 7 includes a protective cylinder 73. A mounting ring 74 is fixedly installed on the outer wall of the protective cylinder 73. A set of sliding rods 75 slides evenly through the outer wall of the mounting ring 74. An arc-shaped protective plate 77 is fixedly installed at the bottom end of each sliding rod 75. A spring 76 is sleeved on the outer wall of the sliding rod 75. When the arc-shaped protective plate 77 is compressed, it slides through the sliding rod 75. Figure 5 It can be observed that there are a large number of curved protective plates 77. When the insulation board below has different angles, the curved protective plates 77 are moved downwards. At this time, a group of curved protective plates 77 will fit against the surface of the insulation board under the action of the spring force of the spring 76, so as to adapt to the insulation board at different angles.

[0029] The bracket 21 is fixedly installed on the top of the base plate 1. Two mounting plates 26 are fixedly installed on one side of the outer wall of the bracket 21. The worm gear 25 is rotatably installed between the opposite sides of the two mounting plates 26. One end of the outer wall of the worm gear 25 passes through the outer wall of the mounting plate 26 and is fixedly installed with a rotating plate 27. By rotating the rotating plate 27, the worm gear 25 can be driven to rotate, and the worm gear 25 can then drive the worm wheel 24 to rotate. The worm wheel 24 can then make the placement frame 22 rotate, thereby adjusting the angle of the insulation board on the placement frame 22. The worm wheel 24 and worm gear 25 have self-locking properties, allowing the placement frame 22 to rotate freely.

[0030] Two L-shaped plates 28 are fixedly installed at the top of the placement frame 22. A threaded rod 29 is threaded through the top of the L-shaped plate 28. A pressure plate 211 is rotatably installed at the bottom of the threaded rod 29. Two limiting rods 210 slide through the top of the L-shaped plate 28. The bottom of the two limiting rods 210 are fixedly connected to the pressure plate 211. A rubber pad is fixedly installed at the bottom of the pressure plate 211. Rotating the threaded rod 29 can drive the pressure plate 211 to move downward, thereby fixing the insulation board below.

[0031] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that one end of the spring 76 is fixedly connected to the mounting ring 74, and the other end of the spring 76 is fixedly connected to the arc-shaped protective plate 77. An electric push rod 71 is fixedly installed at the top of the base plate 1. A connecting plate 72 is fixedly installed at the output end of the electric push rod 71. One end of the outer wall of the connecting plate 72 is fixedly connected to the protective cylinder 73. The electric push rod 71 is existing technology. The electric push rod 71 can drive the protective cylinder 73 to move through the connecting plate 72, so that the arc-shaped protective plate 77 can fit against the insulation board.

[0032] An electric slide rail 3 is fixedly installed at the top of the base plate 1. A movable slide plate 4 is provided at the output end of the electric slide rail 3. An electromagnet 5 is fixedly installed at the bottom end of the movable slide plate 4. A ball 6 is provided on the inner wall of the electromagnet 5. The ball 6 is made of iron material and can be attracted by the electromagnet 5. The electric slide rail 3 is existing technology and can drive the ball 6 to rise to different heights, so that the free fall height of the ball 6 is different.

[0033] The sphere 6 is positioned directly above the protective cylinder 73. The diameter of the sphere 6 is smaller than the inner diameter of the protective cylinder 73, so that when the sphere 6 falls, it can enter the interior of the protective cylinder 73 without colliding with it. At the same time, the protective cylinder 73 has a certain height, which can prevent the sphere 6 from leaving through the opening of the protective cylinder 73 when it bounces off the impact.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when testing the insulation board, first place the insulation board on the placement slot 23 of the placement frame 22. By rotating the threaded rod 29, the clamping plate 211 at the bottom of the threaded rod 29 can move up and down to fix the insulation board placed in the placement slot 23. The limiting rod 210 acts as a guide to prevent the clamping plate 211 from rotating, and the rubber pad increases the friction with the insulation board to prevent the insulation board from moving during the test. When testing the insulation board from different angles, the rotating plate 27 is rotated. The worm gear 25 is driven to rotate, and since the worm gear 25 meshes with the worm wheel 24, it drives the worm wheel 24 to rotate, causing the placement frame 22 to rotate around the rotation axis within the bracket 21. Rotating the placement assembly 2 allows the insulation board to be adjusted to different tilt angles. Combined with the impact of the falling ball 6, it can simulate the impact forces from different directions that the insulation board may experience in actual building scenarios. Compared with traditional devices that can only test from a single vertical direction, this device can more comprehensively detect the compressive strength of the insulation board under various stress angles. The test results are more consistent with actual usage, which is conducive to more accurate evaluation of the quality of the insulation board. It is equipped with a protective cylinder 73 and an arc-shaped protective plate 77. Before the ball 6 impacts the insulation board, the arc-shaped protective plate 77 can be pressed against the surface of the insulation board by the electric push rod 71. If the insulation board angle is different, due to the multiple arc-shaped protective plates 77 and springs 76, when the arc-shaped protective plate 77 moves downward, its elastic deformation allows it to better adhere to the surface of the insulation board. The insulation board can adapt to different angles. If the ball 6 bounces after hitting the insulation board, the bounce will be limited because it is inside the protective cylinder 73 and the arc-shaped protective plate 77. This reduces the probability of the ball 6 causing injury to personnel due to the bounce. When the test is ready, the height of the ball 6 is adjusted by the electric slide rail 3, the electromagnet 5 is de-energized, and the ball 6 falls freely under the action of gravity, impacting the insulation board placed in the placement frame 22 below. The compressive strength is tested by observing the damage to the insulation board under the impact.
