Description

A performance testing device for waterproof coatings Technical Field

[0001] This utility model relates to the field of waterproof coating testing technology, and in particular to a performance testing device for waterproof coatings. Background Technology

[0002] Waterproof coatings are functional coatings used to form a waterproof layer on building surfaces to prevent water penetration. Before use, the waterproof coating needs to be evenly applied to a test fabric before testing its waterproof performance. Current equipment typically clamps the test fabric and brings water into contact with the side of the fabric with the waterproof layer applied, observing the leakage on the other side. Because the water pressure needs to be gradually increased during testing, and the clamping method provides weak fixation for the test fabric, the fabric is prone to slipping back, thus reducing the accuracy of the test results. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies where, as water pressure gradually increases, it is difficult to fix the test cloth using only a clamping device, and the test cloth is prone to backing up. Therefore, this invention proposes a performance testing device for waterproof coatings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a performance testing device for waterproof coatings, including a base platform, on which a water filling platform is fixedly connected, and an anti-reverse assembly. The anti-reverse assembly includes two rotating shafts, both of which are rotatably connected to the base platform. A take-up roller and a baffle are sequentially fixedly connected to the circumference of each rotating shaft. A sliding sleeve is slidably connected to the rotating shaft, and a spring is fixedly connected between the sliding sleeve and the baffle. Two L-shaped plates are symmetrically fixedly connected to the side of the base platform, and a clamping sleeve is fixedly connected to each L-shaped plate. Several sector-shaped blocks are arranged circumferentially on the side of the sliding sleeve, and sector-shaped grooves corresponding to the sector-shaped blocks are opened in the clamping sleeve. A test fabric is fixedly connected between the two take-up rollers, and a clamping assembly is fixedly connected to the base platform.

[0006] Preferably, the clamping assembly includes a clamping frame, which is slidably connected to the base platform. An electric telescopic rod is fixedly connected to the surface of the base platform, and the output end of the electric telescopic rod is fixedly connected to the clamping frame.

[0007] Preferably, the bottom of the clamping frame is bucket-shaped, and the clamping frame has drainage holes inside.

[0008] Preferably, a cross plate is fixedly connected to the circumferential side of the rotating shaft, and a cross groove is opened in the sliding sleeve, with the cross plate and the cross groove slidingly engaged.

[0009] Preferably, a first sprocket is fixedly connected to the end of the shaft, and two second sprockets are symmetrically rotatably connected to the base platform, with a chain belt providing transmission between the first sprocket and the second sprocket.

[0010] Preferably, a gear is fixedly connected to the side axis of the second sprocket, and the two gears mesh with each other.

[0011] Preferably, a lever is fixedly connected to the side of one of the gears.

[0012] Preferably, two perforations are symmetrically opened on the base, and the test fabric passes through the two perforations and abuts against the base.

[0013] The present invention provides a performance testing device for waterproof coatings, which has the following advantages: During use, the spring always pushes the sliding sleeve against the clamp, causing the sector block to be inserted into the sector groove. The sector block and the sliding sleeve are fixedly connected. Due to the influence of the sector block and the sector groove, the sliding sleeve can only rotate in one direction. When the two winding rollers are rotated to tighten the test cloth during use, the test cloth can be prevented from retreating when the water pressure is too high, thereby improving the accuracy of the test results.

[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 1

[0023] Referring to Figures 1-5, this utility model is a performance testing device for waterproof coatings, including a base 1, a water filling platform 2 fixedly connected to the base 1, and an anti-reverse assembly, which includes two rotating shafts 3, both of which are rotatably connected to the base 1. A winding roller 4 and a baffle 5 are fixedly connected to the sides of the rotating shafts 3 in sequence. A sliding sleeve 6 is slidably connected to the rotating shafts 3. A spring 7 is fixedly connected between the sliding sleeve 6 and the baffle 5. Two L-shaped plates 8 are symmetrically fixedly connected to the sides of the base 1. A clamping sleeve 9 is fixedly connected to the L-shaped plates 8. Several fan-shaped blocks 10 are arranged in a circle on the sides of the sliding sleeve 6. A fan-shaped groove 11 corresponding to the fan-shaped blocks 10 is opened in the clamping sleeve 9. A test cloth 21 is fixedly connected between the two winding rollers 4. A clamping assembly is fixedly connected to the base 1.

[0024] The operation process of this embodiment is as follows: apply waterproof coating to test cloth 21, and fix both ends of test cloth 21 to two rotating shafts 3 respectively. When in use, add water into the water filling platform 2 and observe the water leakage of test cloth 21 to complete the test of the waterproof performance of the waterproof coating.

[0025] During use, different amounts of water need to be added to the water filling platform 2 to test the waterproof coating's waterproof performance under different pressures. However, as the water in the water filling platform 2 increases, it becomes difficult to effectively fix the test cloth 21 using only clamps. The test cloth 21 is prone to falling off and retraction, which will cause the test surface of the test cloth 21 to be uneven, thus affecting the accuracy of the test. Therefore, during use, the two rotating shafts 3 are rotated in the opposite direction. The rotation of the rotating shafts 3 drives the winding roller 4 and the sliding sleeve 6 to rotate, tightening the test cloth 21 and keeping its test surface flat. Since the sliding sleeve 6 is always in sliding fit with the rotating shaft 3, the rotation of the rotating shaft 3 also drives the sliding sleeve 6 to rotate. A spring 7 is set between the baffle 5 and the sliding sleeve 6, which can keep the sliding sleeve 6 in close contact with the clamp 9 during rotation.

[0026] Several sector-shaped blocks 10 arranged in a circumferential array on the side of the sliding sleeve 6 move out of the sector-shaped groove 11 when rotating, and then enter the next sector-shaped groove 11 under the influence of the spring 7. Since one side of the sector-shaped block 10 is a straight surface and the other side is an inclined arc surface, it can be inserted and matched with the sector-shaped groove 11. That is, the sliding sleeve 6 can only rotate in one direction towards the arc surface of the sector-shaped block 10. When rotating the rotating shaft 3, it can only tighten the test cloth 21 on the two rotating shafts 3, which avoids the test cloth 21 from retreating when the water pressure is too high, thereby improving the accuracy of the performance test of the waterproof coating.

[0027] Example 2

[0028] When fastening the test fabric 21, it is necessary to rotate the two rotating shafts 3 in the opposite direction, which is quite troublesome. Therefore, please refer to Figures 1-3. Based on the first specific embodiment, the clamping assembly includes a clamping frame 19, which is slidably connected to the base platform 1. An electric telescopic rod 20 is fixedly connected to the surface of the base platform 1. The output end of the electric telescopic rod 20 is fixedly connected to the clamping frame 19. The bottom of the clamping frame 19 is bucket-shaped, and a drainage hole is provided inside the clamping frame 19. A cross plate 12 is fixedly connected to the side of the rotating shaft 3. A sliding sleeve 6 is provided with a cross plate 12. The cross groove 13 and the cross plate 12 are slidably fitted with the cross groove 13. The first sprocket 14 is fixedly connected to the end of the rotating shaft 3. Two second sprockets 15 are symmetrically rotatably connected on the base 1. A chain belt 16 is provided between the first sprocket 14 and the second sprocket 15 for transmission. A gear 17 is fixedly connected to the axis position on the side of the second sprocket 15. The two gears 17 mesh with each other. A handle 18 is fixedly connected to the side of one gear 17. Two through holes are symmetrically opened on the base 1. The test fabric 21 passes through the two through holes and abuts against the base 1.

[0029] The operation process of this embodiment is as follows: The user rotates the lever 18, and the rotation of the lever 18 drives the gear 17 to rotate. Since the two gears 17 mesh with each other, that is, the two gears 17 rotate synchronously in opposite directions. The gear 17 is fixedly connected to the second sprocket 15, and the second sprocket 15 is connected to the first sprocket 14 by a chain belt 16. That is, when the lever 18 is rotated, it can drive the two first sprockets 14 to rotate synchronously in opposite directions, thereby driving the two winding rollers 4 to rotate synchronously in opposite directions to wind up and tighten the test cloth 21, which improves the work efficiency when testing the performance of waterproof coating.

[0030] After the test fabric 21 is rolled up and tightened, the electric telescopic rod 20 retracts, driving the clamping frame 19 to move upward, clamping the test fabric 21 together with the base platform 1 and maintaining it in the testing stage. The test fabric 21 is always in close contact with the base platform 1. The user can observe the water leakage through the seepage holes on the clamping frame 19 to test the waterproof performance of the waterproof coating, further improving the accuracy of the test.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
