Technical Field

[0001] The utility model relates to the technical field of waterproof coil detection, in particular to an impact resistance detection device for waterproof coils. Background Technique

[0002] Waterproof coils are important materials used in construction and infrastructure projects. They can effectively prevent water penetration and protect structures from moisture erosion. Such materials are usually used in walls, roofs, tunnels, roads, and even landfills, etc., as a key waterproof barrier to ensure the overall waterproof performance of the project.

[0003] Existing waterproof coil detection methods rely on a free-fall device that evaluates the impact resistance and waterproofness of a fixed-size coil sample by dropping a hammer onto it. However, this detection process has limitations because the test space of the detection device is fixed, which means that the size of the coil sample must strictly meet the requirements. In actual operation, this often requires on-site workers to precisely cut the sample, increasing the difficulty of preparation work before detection and reducing efficiency. Therefore, an impact resistance detection device for waterproof coils is proposed to solve the above problems. Content of the Utility Model

[0004] The utility model provides an impact resistance detection device for waterproof coils. By adjusting the reverse telescoping of two sets of telescopic support components, waterproof coils of different widths can be accommodated between the two support beams. In this way, it is not necessary to cut the waterproof coil sample before detection, reducing the work difficulty.

Limiting sliders are provided on both sides of the telescopic part, and limiting sliding grooves corresponding to the limiting sliders are provided on both sides of the base. The ends of the limiting sliders can slide through the corresponding limiting sliding grooves. Symmetric racks and rack insertion grooves are provided at the insertion end of the telescopic part. A support beam is provided at the outer end of the telescopic part, and support feet are threadedly installed at both ends of the support beam.

[0013] Further, the gear transmission part includes a gear. Installation shafts with the same inner diameter as its central shaft hole are provided at both ends of the gear. The gear is rotatably arranged at the perforation of the base through the installation shafts, and a bevel gear ring is provided at one end of the gear;

[0014] The racks of the two telescopic support assemblies are respectively located on both sides of the gear and are meshed with it.

[0015] Further, the driving device includes a driving motor arranged on the base. A transmission bevel gear meshed with the bevel gear ring is provided on the driving motor, and a slotted opening for the transmission bevel gear to pass through is provided on the base.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] As Figures 1-5 shown, an impact resistance detection device for waterproof coiled materials in this embodiment includes a base 1, a telescopic support assembly 2, a telescopic drive mechanism 3, and an impact resistance detection mechanism 4. Among them, a hollow cavity is provided inside the base 1, and both ends are open. The number of telescopic support assemblies 2 is two, and they are respectively inserted into the hollow cavity inside the base 1 through the openings at both ends of the base 1. During use, by adjusting the reverse telescoping of the two telescopic support assemblies 2, the support width can be adjusted according to the width of the coiled material sample, and it can be erected on it without precise cutting of the coiled material sample, thereby reducing the preparation work for detection and effectively improving the detection efficiency. The telescopic drive mechanism 3 is arranged in the base 1 and is used to make the two telescopic support assemblies 2 telescopically move in the reverse direction. Through the telescopic drive mechanism 3, the effect of automatic adjustment can be achieved. The impact resistance detection mechanism 4 is arranged on the base 1, and a perforation 102 for the drop hammer to pass through and fall onto the waterproof coiled material is provided on the base 1. The effect of detection is achieved by the free fall of the drop hammer in the impact resistance detection mechanism 4 and passing through the perforation 102 to fall onto the waterproof coiled material.

[0037] Among them, the specific structure of the telescopic support assembly 2 is as Figure 3 shown, including a telescopic part 201 inserted into the base 1 through the opening. Limit sliders 202 are arranged on both sides of the telescopic part 201, and limit sliding grooves 101 corresponding to the limit sliders 202 are arranged on both sides of the base 1. As Figure 2As shown, the end of the limit slider 202 can slide through the corresponding limit chute 101. By sliding the limit slider 202 in the limit chute 101, the function of restricting linear sliding is realized. The length of the limit chute 101 should meet the maximum range of telescoping. The insertion end of the telescoping part 201 is provided with symmetric racks 203 and rack insertion grooves 204. The racks 203 and rack insertion grooves 204 are respectively arranged at two edges of the end of the telescoping part 201. The size of the rack insertion groove 204 should meet the requirement for the insertion of the rack 203, so that the rack 203 of another telescoping support assembly 2 can be inserted therein, thus meeting the installation requirements between the two telescoping support assemblies 2. The outer end of the telescoping part 201 is provided with a support beam 205, and support feet 206 are threadedly installed at both ends of the support beam 205.

[0038] It should be noted that the support foot 206 includes an adjustment bolt that threadedly penetrates the end of the support beam 205. A floor mat is provided at the bottom end of the adjustment bolt. The waterproof coiled material is arranged between the two groups of support beams 205 and at the bottom of the base 1.

[0039] In addition, the specific structure of the telescoping drive mechanism 3 is as Figure 4 shown. The telescoping drive mechanism 3 includes a gear transmission part rotatably arranged at the perforation 102 of the base 1, and a drive device arranged on the base 1 and in transmission connection with the gear transmission part.

[0040] The gear transmission part includes a gear 301. Both ends of the gear 301 are provided with mounting shafts 302 having an inner diameter the same as its central shaft hole. The gear 301 is rotatably arranged at the perforation 102 of the base 1 through the mounting shafts 302. A bevel gear ring 303 is arranged at one end of the gear 301. In this embodiment, the bevel gear ring 303 is arranged at the top end of the gear 301.

[0041] It should be noted that a bearing for the rotational mounting of the gear 301 is arranged at the perforation 102, which is sleeved outside the mounting shaft 302. The central shaft hole of the gear 301 can meet the requirement for passing through during drop hammer testing.

[0042] The racks 203 of the two telescoping support assemblies 2 are respectively located on both sides of the gear 301 and meshed with it. Thus, by rotating the gear 301, the two telescoping support assemblies 2 can be telescopically extended and retracted in opposite directions, achieving the effect of automatically adjusting the distance between them.

[0043] To rotate the drive gear 301, the drive device includes a drive motor 304 disposed on the base 1. A transmission bevel gear 305 meshing with the bevel gear ring 303 is arranged on the drive motor 304. The transmission bevel gear 305 is disposed on the output shaft of the drive motor 304 and can rotate by the power of the drive motor 304. Then, the gear 301 is rotated through meshing with the bevel gear ring 303. A slotted opening 103 for the transmission bevel gear 305 to pass through is provided on the base 1. The gear 301, the drive device, and the slotted opening 103 are all arranged on the top of the base 1 corresponding to the bevel gear ring 303.

[0044] In another embodiment, as Figures 6-9 shown, the impact resistance detection mechanism 4 includes a vertical slideway 41 erected above the perforation 102 by a plurality of support frames 42. In this embodiment, the number of support frames 42 is four and they are diagonal braces. Their bottoms are connected to the base 1 and their tops are connected to the vertical slideway 41, thus erecting the vertical slideway 41 above the perforation 102. There is a gap between the vertical slideway 41 and the perforation 102 that does not affect the falling weight passing through. A falling weight clamping part 43 is slidably arranged in the vertical slideway 41. The falling weight can be fixed from below the perforation 102 through the falling weight clamping part 43 and lifted to a preset height for free-fall detection.

[0045] Furthermore, both ends of the vertical slideway 41 are open, and two symmetrically arranged falling body limiting grooves 410 are provided on the wall surface. The four support frames 42 avoid the positions where the falling body limiting grooves 410 are located.

[0046] The falling weight clamping part 43 includes an electromagnetic suction seat 430. Two falling body limiting blocks 431 respectively sliding through the corresponding falling body limiting grooves 410 are arranged on the outside of the electromagnetic suction seat 430. The falling body limiting blocks 431 movably pass through the corresponding falling body limiting grooves 410. When the electromagnetic suction seat 430 descends, it can be limited to improve stability. The falling weight can be adsorbed by the electromagnetic suction seat 430 through magnetic attraction. At the same time, during detection, the falling weight can be made to free-fall by turning it off. The power control line of the electromagnetic suction seat 430 can penetrate into the vertical slideway 41 from the opening at the top.

[0047] Furthermore, to achieve the effect of automatically lifting the falling weight clamping part 43 and the falling weight, this embodiment further includes a falling weight pulling-up mechanism 5 arranged on the side of the base 1 for lifting the installed falling weight clamping part 43 to the preset lifting point height.

[0048] Among them, as Figure 9As shown, the drop hammer pulling mechanism 5 includes an extension plate 501 arranged on the side of the base 1, and a winding mechanism 502 and a winding drive device 503 whose output end is connected to the rotating shaft of the winding mechanism 502 are arranged on the top of the extension plate 501. The winding mechanism 502 is composed of a U-shaped seat and a winding drum rotatably arranged in the U-shaped seat through a rotating shaft. The winding drum can be rotated by the power of the winding drive device 503, thereby achieving the effect of lifting and lowering the drop hammer clamping part 43.

[0049] It should be noted that the winding drive device 503 is composed of a motor and a reducer.

[0050] A pulley assembly is provided at the top of the vertical slideway 41 , and a pull rope is wound around the outside of the reel of the reeling mechanism 502 . The end of the pull rope passes through the pulley assembly and forms a wrap angle before being connected to the top of the electromagnetic suction seat 430 .

[0051] The pulley assembly includes an inverted L-shaped support frame 411 arranged at the top of the vertical slide 41 , and a pulley 412 located above the top opening of the vertical slide 41 is arranged at the end of the inverted L-shaped support frame 411 .

[0052] A lifting ear 432 for connecting with a pull rope is provided on the top of the electromagnetic suction base 430 .

[0053] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
