Description

Technical Field

[0001] The invention relates to the field of coiled material wear-resistant testing equipment, in particular to a wear-resistant testing equipment and method for waterproof coiled material. Background Art

[0002] Waterproof membrane is a rollable sheet-like waterproof material that is widely used in building waterproofing projects. It can effectively prevent the leakage of rainwater, groundwater, etc. and ensure the waterproof performance of the building.

[0003] If waterproofing membranes are used for roofing and are exposed to the elements for a long time, they will be affected by natural factors such as wind, sun, and rain, and will undergo qualitative changes. When personnel are inspecting and maintaining equipment on the roof, friction will occur between the soles of their shoes and the surface of the membranes. If the waterproofing membranes have poor wear resistance, they will easily wear and break under these frictions, which will lead to failure of the waterproofing layer and leakage on the roof.

[0004] In addition, there are often multiple types of work in construction. After the waterproofing membrane is laid, subsequent construction activities of other types of work may cause friction to it. For example, after the roof waterproofing construction is completed, when the insulation layer and protective layer are constructed, the handling of construction materials and the operation of construction machinery may come into contact with the waterproofing membrane and cause friction.

[0005] Therefore, by conducting abrasion resistance tests on waterproof membranes, it is possible to screen out those waterproof membranes that can withstand the impact of cross-operation friction, thus ensuring that the quality of the entire waterproofing project is not affected by subsequent construction.

[0006] At present, there are certain limitations in the industry for testing the wear resistance of waterproof membranes. Traditional wear resistance testing methods mostly rely on manual operation, where testers hold abrasive tools and rub the surface of waterproof membranes in a specific way, and then judge their wear resistance based on the observed wear condition of the membrane surface. However, this manual testing method has many disadvantages.

[0007] First, manual operation cannot guarantee the consistency of test conditions. Due to differences in operating habits, force control, friction speed and path selection among different testers, different results may be obtained even when testing the same batch of waterproof membranes, resulting in poor accuracy and repeatability of the test results, and unable to provide a reliable basis for the quality assessment of waterproof membranes.

[0008] Secondly, manual testing is inefficient. Manually operating abrasive tools for friction testing requires a lot of time and effort to complete each test. For large-scale production of waterproof membranes, it is difficult to meet the needs of fast and efficient testing, which affects production efficiency and product launch cycle to a certain extent.

DETAILED DESCRIPTION

[0041] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0043] In order to achieve wear resistance treatment of waterproof coiled materials with high efficiency and accuracy, this embodiment provides a wear resistance test device for waterproof coiled materials. When using the test device to perform wear resistance test of waterproof coiled materials, it is necessary to cut waterproof coiled materials of a certain size and place the cut waterproof coiled materials on the test device, and then the wear resistance test treatment of the waterproof coiled materials can be completed by the test device.

[0044] like Figure 1 , Figure 2 As shown, specifically, the test equipment includes a bracket 1, an auxiliary mechanism 2, a driving mechanism 3, multiple groups of supporting components 5, and multiple groups of grinding components 4. The bracket 1 is set as a vertical frame structure, and multiple groups of supporting components 5 are installed on the bracket 1 and are distributed along the height direction of the bracket 1. A grinding component 4 is arranged above each group of supporting components 5, and the end of the grinding component 4 protrudes from the bracket 1. At the same time, multiple groups of grinding components 4 simultaneously penetrate the auxiliary mechanism 2 and the driving mechanism 3. Therefore, the height of the grinding component 4 can be adjusted under the operation of the auxiliary mechanism 2, so that the bottom of the grinding component 4 is in contact with the waterproof coiled material installed on the supporting component 5, and the bottom of the grinding component 4 is forced to rotate relative to the waterproof coiled material under the action of the driving mechanism 3, thereby realizing the grinding of the waterproof coiled material. Because multiple groups of supporting components 5 and grinding components 4 are provided, multiple samples of waterproof coiled materials can be polished at the same time, thereby improving the accuracy of the test.

[0045] like Fig. 9 As shown, in order to stably install the waterproof membrane sample on the supporting assembly 5, the supporting assembly 5 includes a supporting plate 51 and a pressing frame 54. A second threaded hole 52 is provided on the ear plate at the edge of the supporting plate 51, and a bolt is penetrated through the edge of the pressing frame 54. Therefore, after the waterproof membrane sample is laid flat on the supporting plate 51, the pressing frame 54 is placed on the waterproof membrane, and the end thread of the bolt is penetrated through the second threaded hole 52, and then the pressing frame 54 squeezes the waterproof membrane under the action of the bolt, so that the waterproof membrane is stably installed on the supporting plate 51.

[0046] like Figure 5 , Figure 6 , Figure 8 As shown, in order to grind the waterproofing membrane, the grinding assembly 4 includes a support plate 44 and a grinding wheel 41. The central axis fixedly arranged on the upper side of the grinding wheel 41 passes through the bearing seat 42, and a second sprocket 43 is arranged on the top of the central axis. The bearing seat 42 is installed at the end of the support plate 44. The driving mechanism 3 includes a second motor, a driving rod 33 and a plurality of first sprockets 32. The driving rod 33 passes through the end of the support plate 44 protruding from the bracket 1, and the plurality of first sprockets 32 are sleeved on the driving rod 33 along the height direction of the driving rod 33. At the same time, the plurality of first sprockets 32 are directly opposite to the plurality of second sprockets 43. Therefore, when the first sprocket 32 ​​is connected to the second sprocket 43 through a chain, the rotation of the driving rod 33 can be used to control the rotation of the plurality of grinding wheels 41, thereby grinding the plurality of waterproofing membrane samples at the same time. In order to control the rotation of the driving rod 33, a second motor is arranged at the bottom of the bracket 1, and a third sprocket is arranged on the power output shaft of the second motor. The third sprocket is connected to the lowermost first sprocket 32 ​​by a chain. Therefore, the driving rod 33 can be controlled to rotate under the action of the second motor, thereby driving the multiple grinding wheels 41 to rotate.

[0047] like Figure 5 , Figure 8 As shown, in order to control the lifting and lowering of the grinding wheel 41 so that it contacts the waterproofing coiled material, the auxiliary mechanism 2 includes a first motor 21 and a plurality of threaded rods 23, the plurality of threaded rods 23 are arranged along the height direction of the driving rod 33, and the adjacent ends of the threaded rods 23 are connected by a coupling, and the bottom of the lowest threaded rod 23 is connected to the power output shaft of the first motor 21 by a coupling. In addition, the threaded rods 23 are matched with the support plates 44 one by one, and a first threaded hole 46 is arranged at the end of the support plate 44 protruding from the bracket 1, so that the threaded rod 23 is threaded through the first threaded hole 46, so when the first motor 21 is working, the plurality of threaded rods 23 are controlled to rotate synchronously, and then the plurality of support plates 44 are controlled to lift synchronously, forcing the plurality of grinding wheels 41 to lift and lower, providing convenience for the grinding wheels 41 to descend to contact the waterproofing coiled material, or for the grinding wheels 41 to rise and detach from the waterproofing coiled material.

[0048] The first motor 21 and the second motor can be set as a servo motor, a stepper motor, etc., and are both installed on the bracket 1 through the connecting frame 22, that is, the connecting frame 22 is installed on the bracket 1 through bolt connection, and the bottom of the connecting frame 22 is inserted into the insertion hole 13 of the bracket 1, so that the first motor 21 and the second motor are stably installed on the bracket 1. In addition, in order to stably install the driving rod 33, the bottom of the driving rod 33 can be connected and inserted into the connecting frame 22 below it through a bearing.

[0049] In order to control the operation of the first motor 21 and the second motor, an electrical control box is also provided at the bottom of the bracket 1. The electrical control box includes at least a controller (such as a PLC), a relay, a contactor, a switching power supply, etc. The power lines of the first motor 21 and the second motor are connected to the switching power supply, and are connected to the relay, the contactor, the controller, etc. to form a control circuit, thereby controlling the operation of the motor.

[0050] In order to detect the lifting and lowering of the support plate 44, a displacement sensor 24 is arranged on the connecting frame 22. The end of the displacement sensor 24 away from the connecting frame 22 is connected to the lowermost support plate 44, and the power line and signal line of the displacement sensor 24 are connected to the electrical control box, thereby providing power for the displacement sensor 24 to operate. At the same time, the displacement sensor 24 can send information to the controller. After processing the received displacement sensor signal, the controller can control the operation of related equipment (such as motors) through relays and contactors.

[0051] like Figure 8 As shown, in order to monitor the pressure applied by the grinding wheel 41 to the waterproof coiled material, a pressure sensor 47 is provided below the support plate 44. The bottom surface of the pressure sensor 47 is lower than the bottom surface of the grinding wheel 41. Therefore, during the lifting and lowering process of the support plate 44, when the grinding wheel 41 contacts the waterproof coiled material, the bottom surface of the pressure sensor 47 contacts the support plate 51. When the support plate 44 continues to descend, the pressure applied by the grinding wheel 41 to the waterproof coiled material can be monitored by the pressure sensor 47. If the bottom surface of the pressure sensor 47 is flush with the bottom surface of the grinding wheel 41, the pressure sensor 47 needs to contact the waterproof coiled material to obtain accurate pressure data. In addition, the power line and signal line of the pressure sensor 47 are connected to the electrical control box, and the pressure sensor 47 can send information to the controller. After the controller processes the received signal of the pressure sensor 47, it can control the operation of related equipment (such as a motor) through relays and contactors.

[0052] like Figure 6 , Figure 7As shown, in order to ensure that the driving rod 33 and the first sprocket 32 ​​are stably connected and do not affect the lifting and lowering of the support plate 44 and the grinding wheel 41, a slot 31 is provided on the driving rod 33. The slot 31 is provided along the height direction of the driving rod 33, and the top is provided with an opening. A sleeve 35 is fixedly provided at the first sprocket 32, and a column 34 is fixedly provided on the inner side wall of the sleeve 35. The sleeve 35 is sleeved on the driving rod 33, and the column 34 is located in the slot 31. Therefore, the sleeve 35 is sleeved on the driving rod 33 to facilitate the lifting and lowering of the sleeve 35 relative to the driving rod 33. In addition, with the cooperation of the column 34 and the slot 31, the sleeve 35 can drive the first sprocket 32 ​​and the driving rod 33 to rotate synchronously.

[0053] like Figure 8 As shown, in order to make the first sprocket 32 ​​rise and fall with the support plate 44, a countersunk hole 45 is provided on the support plate 44, the driving rod 33 is arranged through the countersunk hole 45, and the bottom of the sleeve 35 is inserted into the countersunk hole 45 through a bearing connection. Therefore, the sleeve 35 is stably and movably connected to the support plate 44. Therefore, the sleeve 35 can be driven to rise and fall in the process of the support plate 44 driving the grinding wheel 41 to rise and fall.

[0054] like Figure 3 , Figure 4 , Fig. 9 As shown, in order to stably support the supporting assembly 5, the bracket 1 includes a top frame 12, a bottom frame 11, and a plurality of supporting rods 14. The bottom frame 11 and the top frame 12 are respectively arranged at the upper and lower ends of the supporting rod 14, and the upper and lower ends of the supporting rod 14 are provided with threaded structures. At the same time, the ends of the supporting rod 14 are threadedly inserted into the top frame 12 and the bottom frame 11. In addition, a polygonal column 17 is arranged at the bottom of the supporting rod 14. A connecting plate 53 is fixedly arranged at the end corner of the supporting plate 51. The cross section of the connecting plate 53 is arranged as a U-shaped structure, and the openings of the connecting plate 53 face the same direction, so the connecting plate 53 is sleeved on the supporting rod 14. In addition, a plurality of trays 15 are fixedly arranged on the supporting rod 14, and a recessed groove 16 is arranged on the tray 15. The connecting plate 53 is sleeved on the supporting rod 14, and the bottom is inserted into the recessed groove 16. The connecting plate 53 is stably installed on the bracket 1, and the supporting assembly 5 can be disassembled according to needs, which provides convenience for replacing the waterproof membrane.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
