Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation board performance detection, in particular to an impact resistance detection instrument for building thermal insulation boards. Background Art

[0002] Insulation treatment of building exterior walls, roofs, floors, etc. is currently a very important construction link. For this reason, insulation boards are generally installed on the exterior surface of buildings for insulation treatment. Insulation boards must not only have good thermal insulation properties during service, but also withstand the influence of environmental factors such as wind and sun. Sometimes they are also subject to wind load impact, accidental collisions, etc., which pose a threat to the integrity and stability of the insulation boards. Impact testing of insulation boards to evaluate their durability and safety under extreme conditions is an important task in the production process of insulation boards. Currently, the test is usually carried out by using a steel impact ball to freely fall from the air to impact the insulation board below, and observe and record the changes in the appearance of the insulation board after the impact, the degree of damage, and whether there is delamination or falling off.

[0003] Although this testing method is simple, fast, and highly efficient, the point at which the steel ball lands cannot be changed. Therefore, if different parts of the insulation board are to be tested, the staff must move the insulation board. This random movement increases the randomness of the test results when testing different test samples, affecting the accurate assessment of the test sample performance. Furthermore, since the insulation board is not fixed during the test, it bounces and moves after being impacted by the steel ball, affecting the accuracy of the test results. However, if the insulation board is fixed directly before testing, the fixing mechanism must be constantly disassembled during the test of different parts, resulting in high workload and low efficiency. Utility Model Content

[0004] To address the above-mentioned issues, the present invention provides an instrument for testing the impact resistance of building insulation boards. This instrument not only facilitates impact testing of different locations on the insulation board, but also eliminates the need to move the insulation board, thus avoiding adverse effects on the accuracy of the test results. To achieve the above-mentioned objectives, the technical solution of the present invention is as follows.

[0005] A tester for the impact resistance of building insulation boards comprises: a test bench, support rods, connecting plates, sliding rods, screws, rotating wheels, a slider, an electromagnetic adsorption seat, an impact ball, and a fixing mechanism. The four support rods are vertically fixed at the four corners of the test bench, and the upper portions of the two front and rear support rods on the left side and the upper portions of the two front and rear support rods on the right side are connected via the connecting plates. The sliding rod is arranged parallel to the screw, and the two ends of the screw are respectively fixedly connected to the two connecting plates. The two ends of the screw are respectively rotatably connected to the two connecting plates, and one end of the screw is connected to the rotating wheel to drive the screw to rotate. The slider is simultaneously sleeved on the sliding rod and the screw, and the slider is slidably connected to the sliding rod and threadedly connected to the screw. The electromagnetic adsorption seat is fixed to the lower surface of the slider, and the impact ball is adsorbed on the lower surface of the electromagnetic adsorption seat. The fixing mechanism is connected to the lower portion of the support rod and is used to detachably fix the insulation board to be tested placed on the test bench.

[0006] Furthermore, a scale rod is provided between the slide rod and the lead screw, and the three are parallel and horizontally arranged. The scale rod has a scale on its upper surface from one end to the other. The upper surface of the slider has an open slot through which the scale rod moves, and the open slot has a horizontal positioning line located above the scale rod, the positioning line being perpendicular to the scale rod.

[0007] Furthermore, the positioning line is a rigid rod, which is located in the channel in the slider and passes through the open slot.

[0008] Furthermore, the upper surface of the sliding block has a screw hole connected to the channel, wherein a first fastener is threadedly connected to fix the positioning wire in the channel.

[0009] Furthermore, the top of the scale rod is flat, and the scale is located on the plane.

[0010] Furthermore, the end of the connecting plate has a sleeve, which is movably sleeved on the support rod, and the sleeve is detachably fixed to the support rod through a second fastener to adjust the height of the impact ball and perform tests under different conditions.

[0011] Furthermore, an arc-shaped groove is provided on the lower surface of the electromagnetic adsorption seat, and the impact ball is adsorbed in the arc-shaped groove.

[0012] Furthermore, the fixing mechanism includes a threaded tube, a fixing plate, and a handwheel, wherein: the threaded tube is sleeved on the support rod and the two are threadedly connected; the fixing plate is movably sleeved on the support rod through a through hole at one end thereof, and the fixing plate is located at the bottom of the threaded tube; the handwheel is sleeved on the outer wall of the threaded tube and the two are fixedly connected.

[0013] Furthermore, a spring is sleeved on the support rod, and the fixing plate is supported on the spring.

[0014] Furthermore, a bracket is fixed on the bottom surface of the test bench to support the test bench at a certain height.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the impact resistance tester of the present invention enables the electromagnetic adsorption seat to move with the impact ball by movably connecting the slider to the slide rod and the lead screw. This test method does not require moving the insulation board to be tested below, but rather gradually performs impact tests on the upper surface of the insulation board from one side to the other, thereby achieving orderly testing of multiple parts. This helps to avoid the problem that in the traditional test method, when the staff moves the insulation board to change the test position, the movement is relatively random, which increases the randomness of the collected test results and affects the accurate evaluation of the insulation board performance. At the same time, the present invention can conveniently control the spacing distance of the movement of the electromagnetic adsorption seat through the special structure of the slider and the cooperation between the slider and the scale rod and the positioning line, so that the test sites on different insulation boards to be tested are consistent, thereby improving the accuracy of the measurement results and facilitating the accurate evaluation of the performance of different insulation boards to be tested.

[0022] For the convenience of description, if the words "up", "down", "left" and "right" appear in the present invention, they only indicate that they are consistent with the up, down, left and right directions of the drawings themselves, and do not limit the structure. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to needs to have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0023] It should be noted that the following detailed description is illustrative and intended to further illustrate the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which the present invention pertains. The present invention's building insulation board impact resistance tester will now be further described with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figure 1 and Figure 2 , an example of a building insulation board impact resistance tester is provided, comprising: a test bench 1, a support rod 2, a connecting plate 3, a sliding rod 4, a screw 5, a rotating wheel 6, a slider 7, an electromagnetic adsorption seat 8, an impact ball 9 and a fixing mechanism. Specifically: the test bench 1 is arranged horizontally, and the four support rods 2 are vertically fixed at the four corners of the test bench 1. The connecting plate 3 is composed of two pieces, and the upper parts of the front and rear two support rods 2 on the left side are connected to form a whole through a vertically arranged connecting plate 3. The upper parts of the front and rear two support rods 2 on the right side are also connected to form a whole through a vertically arranged connecting plate 3.

[0025] The slide rod 4 and the lead screw 5 are both arranged horizontally and parallel to each other, wherein the left and right ends of the lead screw 4 are respectively fixedly connected to the side walls of the two connecting plates 3. The two ends of the lead screw 5 are respectively rotatably connected to the bearings in the two connecting plates 3, and one end of the lead screw 5 passes through the bearings and the connecting plates 3 and is connected to the rotating wheel 6, so that a staff member can drive the lead screw 5 to rotate by turning the rotating wheel 6. The slider 7 is simultaneously sleeved on the slide rod 4 and the lead screw 5 through its two through holes, and the slider 7 is slidably connected to the slide rod 4 and threadedly connected to the lead screw 5. Therefore, when the lead screw 5 is driven to rotate, the slider 7 can move along the slide rod 4 and the lead screw 5.

[0026] The electromagnetic adsorption seat 8 is fixed on the lower surface of the slider 7. An electromagnet is installed in the electromagnetic adsorption seat 8. When powered on, the impact ball 9 can be adsorbed on the lower surface of the electromagnetic adsorption seat 8. When powered off, the impact ball 9 is released to fall freely to perform an impact test on the insulation board 10 to be tested placed on the test bench 1 below. In addition, the switch that controls the power on and off of the electromagnet can be fixed on the electromagnetic adsorption seat 8 to facilitate the operation of the tester. The fixing mechanism is connected to the lower part of the support rod 2 and is used to detachably fix the insulation board 10 to be tested placed on the test bench 1 to prevent the insulation board 10 from bouncing or moving when it is impacted by the impact ball 9.

[0027] During the test, the insulation board 10 to be tested is fixed on the test bench 1 by the fixing mechanism, and then the impact ball 9 is released to perform the impact test. Generally, in order to improve the accuracy of the test results, it is necessary to test different parts of the insulation board 10. Therefore, the lead screw 5 can be driven to rotate and the electromagnetic adsorption seat 8 can be moved to one end of the lead screw 5, such as Figure 1 The left end of the electromagnetic adsorption seat 8 is moved to the left by a certain distance after completion, and the impact ball 9 is re-adsorbed on the electromagnetic adsorption seat 8, and then released to test again. Repeat the above steps, and test gradually from the left to the right of the insulation board 10 to form multiple test parts, thereby realizing orderly testing of multiple parts, and recording the test results after each test is completed. The monitor of this embodiment helps to avoid the problem that when the staff moves the insulation board to change the test position in the traditional testing method, the movement is relatively random, which increases the randomness of the collected test results and affects the accurate evaluation of the performance of the insulation board.

[0028] In another embodiment, reference Figure 2 and Figure 3 , there is a horizontally arranged scale rod 11 between the slide rod 4 and the lead screw 5 of the above-mentioned building insulation board impact resistance tester. The left and right ends of the scale rod 11 are respectively fixed on the inner side walls of the two connecting plates 3, and the slide rod 4, the lead screw 5 and the scale rod 11 are parallel to each other. The upper surface of the scale rod 11 has continuously distributed scales from the left end to the right end. The top of the scale rod 11 is flat, and the scale is located on the plane. There is an open groove 701 on the upper surface of the slider 7, which passes through the slider 7 from left to right. The slot width of the open groove 701 is larger than that of the scale rod 11, so that the scale rod 11 can move through the open groove 701 without affecting the left and right movement of the electromagnetic adsorption seat 8.

[0029] A horizontal positioning line 702 is fixed at the center of the opening slot 701 and is located above the scale rod 11. The positioning line 702 is perpendicular to the scale rod 11. The positioning line 702 is mainly used to determine the interval distance of the movement of the magnetic adsorption seat 8. Through the special structure of the slider 7 of this embodiment and the cooperation between the slider 7, the scale rod 11, and the positioning line 702, the interval distance of the movement of the electromagnetic adsorption seat 8 can be conveniently controlled (for example, a test is performed every 10 cm), so that the test sites on different insulation boards 10 to be tested are consistent, the accuracy of the measurement results is improved, and the performance of different insulation boards to be tested is accurately evaluated.

[0030] In a more specific embodiment, reference Figure 3 In the above embodiment, the positioning wire 702 is a rigid rod made of metal (such as stainless steel, aluminum alloy, copper alloy, etc.), which is located in the channel of the slider 7 and passes through the open slot 701. In a more preferred embodiment, the upper surface of the slider 7 has a screw hole 703 connected to the channel, in which a first fastener 704 (such as a bolt or screw) is threadedly connected. After the positioning wire 702 is inserted into the channel, the first fastener 704 is tightened to removably fix the positioning wire 702 in the channel. After loosening the first fastener 704, the positioning wire 702 can be removed from the channel. Therefore, the length of the positioning wire 702 can be appropriately lengthened so that at least one end of it is exposed outside the electromagnetic adsorption seat 8, or other types of rods can be used to push the positioning wire 702 out of the channel for a certain length before removing the positioning wire 702.

[0031] In another embodiment, the end of the connecting plate 3 of the above embodiment is fixedly connected with a sleeve 301, and the sleeve 301 is movably sleeved on the support rod 2, and the sleeve 301 is detachably fixed to the support rod 2 by a second fastener 302 (such as a bolt or screw, etc.), so that the overall structure formed by the connecting plate 3, the sliding rod 4, the screw 5, the rotating wheel 6, the slider 7 and the electromagnetic adsorption seat 8 can be raised and lowered, and its height can be adjusted to perform tests under different height conditions and obtain more comprehensive test results.

[0032] In another embodiment, the electromagnetic adsorption seat 8 in the above embodiment has an arc-shaped groove on its lower surface, and the impact ball 9 is adsorbed in the arc-shaped groove, so that the impact ball 9 is more stably adsorbed on the electromagnetic adsorption seat 8.

[0033] In a more specific embodiment, reference Figure 1 and Figure 4The fixing mechanism in the above embodiment includes a threaded tube 12, a fixing plate 13 and a handwheel 14. The threaded tube 12 has an internal thread on its inner wall, and the threaded tube 12 is sleeved on the support rod 2 and the two are threadedly connected. The fixing plate 13 is movably sleeved on the support rod 2 through the through hole at one end thereof, and the fixing plate 13 is located at the lower part of the threaded tube 12. The handwheel 14 is sleeved on the outer wall of the threaded tube 12 and the two are fixedly connected. When in use, one end of the fixing plate 13 is supported on the upper surface of the insulation board 10, and then the threaded tube 12 is driven to rotate and move downward by the handwheel 14, and then the fixing plate 13 is squeezed and pressed against the upper surface of the insulation board 10, thereby fixing the insulation board 10 on the test bench 1 to prevent the insulation board 10 from bouncing or moving when it is impacted by the impact ball 9.

[0034] In another embodiment, the support rod 2 in the above embodiment is sleeved with a spring 15, and the fixed plate 13 is supported on the spring 15, thereby avoiding the problem of the tester needing to lift the fixed plate 13 when placing the insulation board 10 on the test bench 1. When the fixed plate 13 is squeezed and pressed against the upper surface of the insulation board 10 by the threaded tube 12, the spring 15 is in a compressed state. After the test is completed, after rotating the threaded tube 12 to move upward, the spring 15 automatically resets and lifts the fixed plate 13, making it easier to remove the insulation board 10 from the test bench 1. The fixed plate 13 can also be turned to the outside of the support rod 2 first, and then the insulation board 10 can be removed from the test bench 1.

[0035] In another embodiment, reference Figure 1 In the above embodiment, a bracket 16 is fixed on the bottom surface of the test bench 1 to support the test bench 1 at a certain height.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
