Description

Technical Field

[0001] The present invention relates to the field of building material testing technology and equipment, and in particular to a fatigue resistance testing device for an enhanced TPR waterproof membrane. Background Art

[0002] TPR is the abbreviation of thermoplastic rubber (Thermoplastic Polyurethane), a new type of plastic material that combines the softness of rubber and the durability of plastic. It is a material with excellent comprehensive performance. In the 1960s, with the emergence of TPR materials, waterproof membranes with TPR as the main raw material were quickly used in roof waterproofing and other fields in construction projects due to their excellent waterproof performance and softness; after the 1980s, with the emergence of enhanced processes such as coating processes, enhanced TPR further improved the performance of waterproof membranes; after the 21st century, enhanced TPR waterproof membranes have been widely used in domestic and foreign markets and have become one of the mainstream products in the building waterproofing industry.

[0003] With the expansion of the application scope of enhanced TPR waterproof membrane, higher requirements are placed on its durability during long-term use, especially in complex and extreme environments, which require it to have good fatigue resistance. In the early days, simple tests through manual repeated bending often failed to achieve accurate quantitative evaluation, so an automated testing device was needed for quantitative detection; TPR waterproof membrane will be subject to long-term fatigue effects of factors such as temperature changes and wind and rain erosion during use, and its service life needs to be verified through accelerated fatigue testing. The emergence of fatigue resistance testing devices has gradually become an important means to ensure the quality of TPR waterproof membranes. The device uses automated testing technology. By setting different temperature change ranges, number of cycles and other parameters, it can simulate the environmental changes of waterproof membranes in actual use, thereby examining the durability of waterproof membranes.

[0004] For example, Chinese patent CN107345876B discloses a testing system for building waterproof membranes, including a bracket, a motor, a screw and a linear guide rail, which can analyze the performance indicators of the waterproof membranes by detecting the surface tension of the waterproof membranes under different environments; for another example, Chinese patent CN112577815B discloses a method for detecting the tearing performance of asphalt waterproof membranes, including two sets of clamping structures, a connecting block and a clamping device arranged at the bottom of the connecting block, which can reduce the possibility of the asphalt waterproof membranes falling off during testing; for another example, Chinese patent CN107859077B discloses an effective testing method and device for a test instrument line passing through a raft foundation waterproof membrane, including a test sleeve, a fixed support plate and a waterproof plate, which can effectively protect the waterproof membrane of the raft foundation and conduct effective testing. However, the above-mentioned devices have the following deficiencies in their specific applications: in actual applications, some areas in northwest my country are under a polar continental climate for most of the year. This climate type is characterized by drastic temperature differences between day and night, especially in spring and autumn each year. The temperature difference between day and night in the above-mentioned areas can reach more than 30 degrees Celsius. Such drastic temperature differences will cause the waterproof membrane to repeatedly expand and contract, thereby generating stress concentration at the structural nodes. Coupled with rain erosion and melting ice and snow, it is easy to cause node damage and premature aging of the waterproof membrane. The above-mentioned test devices can only perform simulation tests on the waterproof membrane under normal temperature conditions, which cannot meet the testing requirements of these special climate areas and are not widely applicable. At the same time, the above-mentioned test devices are difficult to specifically test the impact of an environment with large temperature differences on the premature aging of the waterproof membrane, and cannot truly reflect the long-term fatigue resistance of the waterproof membrane in special environments, and are not practical enough.

A cooling pipe network 4024 is provided, and the output end and the input end of the first cooling pipe network 4024 are respectively connected to the two ends of the first three-way pipe 4023 away from the first water pump 4022. The two ends on the other side of the top of the first cooling water tank 4021 are symmetrically provided with spring bases 4025, the bottom end of the spring base 4025 is provided with a spring 4026, and the top end of the spring 4026 is provided with a limit seat 4027 that cooperates with the bottom end of the upper rotating plate 406. One end of the top of the lower mounting plate 402 is provided with a first L-shaped clamping block 4028; a second cooling water tank 4061 is provided on one side of the top of the upper rotating plate 406 (in addition, in specific applications, the second cooling water tank 4061 stores coolant). A second water pump 4062 is provided in the middle of one side of the top of the second cooling water tank 4061 (in addition, in specific applications, the bottom end of the second water pump 4062 is connected to the top of the second cooling water tank 4061). A second three-way pipe 4063 is connected to one side of the second water pump 4062. A second cooling pipe network 4064 is provided inside the upper rotating plate 406, and the output and input ends of the second cooling pipe network 4064 are connected to the ends of the second three-way pipe 4063 away from the second water pump 4062. A second L-shaped clamping block 4065 is provided at one end of the top of the upper rotating plate 406. This allows repeated bending loads to be applied to the waterproof membrane under low temperature conditions. By evaluating the degree of deformation and damage of the waterproof membrane during multiple bending cycles, the fatigue resistance of the waterproof membrane at low temperatures can be tested.

[0034] The working principle of the low-temperature fatigue resistance testing mechanism 4 is as follows: first, the enhanced TPR waterproof membrane to be tested is placed between the lower mounting plate 402 and the upper rotating plate 406 by the robotic arm 7, and one end of one side of the enhanced TPR waterproof membrane is fixed by the first L-shaped block 4028, and the other end of the one side of the enhanced TPR waterproof membrane is fixed by the second L-shaped block 4065, then the first water pump 4022 is started, and the coolant is sent from the first cooling water tank 4021 to the first cooling pipe network 4024 through the first T-tube 4023 to cool the lower mounting plate 402, and at the same time, the second water pump 4062 is started, and the coolant is sent from the second cooling water tank 4061 to the second cooling pipe network 4064 through the second T-tube 4063 to cool the upper rotating plate 406, thereby putting the enhanced TPR waterproof membrane to be tested in a low-temperature test environment;

[0035] Then, by starting the driving motor 5, the first rotating shaft 4011 is driven to rotate, and the first rotating shaft 4011 drives the first synchronous pulley 4015 to rotate. Since the first synchronous pulley 4015 is rotationally connected to the outer side of the synchronous belt 4018, and the second synchronous pulley 4017 is rotationally connected to the inner side of the synchronous belt 4018, under the cooperation of the auxiliary wheel 4016, the first synchronous pulley 4015 drives the second synchronous pulley 4017 to rotate through the synchronous belt 4018, and the rotation directions of the first synchronous pulley 4015 and the second synchronous pulley 4017 are opposite, and the second synchronous pulley 4017 drives the second rotating shaft 4012 to rotate. Then, when the first rotating shaft 4011 and the second rotating shaft 4012 respectively drive the cam 4014 to rotate, the rotation directions of the two sets of cams 4014 are also opposite, and finally the reverse movement of the cam 4014 generates a vibration force in the vertical direction, which is transmitted to the lower mounting plate 402;

[0036] At the same time, since the rotating sleeve 405 between the two sets of fixed sleeves 403 can rotate around the fixed rotating shaft 404, the upper rotating plate 406 can rotate around the fixed rotating shaft 404. At this time, the vibration exerted on the lower mounting plate 402 will be transmitted to the upper rotating plate 406 through the spring 4026, so that the upper rotating plate 406 can be repeatedly rotated within a certain angle range with the lower mounting plate 402 under the action of the spring 4026, thereby applying a repeated bending load to the enhanced TPR waterproof membrane to be tested. Since the enhanced TPR material has the elastic properties of rubber, the enhanced TPR waterproof membrane to be tested can be repeatedly bent at a certain angle under the action of the bending load, and finally a low-temperature repeated bending test is carried out on the enhanced TPR waterproof membrane to examine the performance of the enhanced TPR waterproof membrane in resisting bending fatigue in a low-temperature environment.

The inner side of the end of the triangular fixing block 6036 is penetrated by A sliding rod 6037 is provided that cooperates with the triangular mounting block 6031 (in addition, in specific applications, the inner side of the end of the triangular fixing block 6036 is movably connected to the sliding rod 6037, and the bottom end of the sliding rod 6037 is fixedly connected to the triangular mounting block 6031). The outer sides of the ends of the triangular fixing block 6036 are provided with drive connecting arms 6038 that cooperate with the rectangular mounting plate 6032 (in addition, in specific applications, one end of the drive connecting arm 6038 is connected to the outer side of the end of the triangular fixing block 6036 via an axis). One side of the triangular fixing block 6036 is provided with a fixed connecting arm 6039 that cooperates with the fixed connecting shell 6025. This allows the test temperature to be controlled at a high temperature to apply an extrusion load to the waterproof membrane, and water in the circular pressure water tank is sprayed upward onto the waterproof membrane to observe whether the waterproof membrane has leaks or breaks, thereby evaluating the waterproof membrane's anti-seepage performance at high temperatures.

[0038] The working principle of the high temperature fatigue resistance test mechanism 6 is as follows: First, the reinforced TPR waterproof membrane to be tested is taken out from the pre-cooling and pre-heating conveying mechanism 8 by the mechanical arm 7 and placed on the top of the annular mounting plate 6026. Since the movable bottom plate 6022 can rotate between the two sets of fixed plates 6021, the fixed connection shell 6025 can also rotate between the two sets of fixed plates 6021. Then, the first cylinder 6023 is started, and the output shaft of the first cylinder 6023 drives the fixed connection shell 6025 through the driving block 6024. The fixed connecting shell 6025 rotates between the two sets of fixed plates 6021, thereby driving the triangular fixed block 6036 to rotate via the fixed connecting arm 6039. The triangular fixed block 6036 drives the triangular mounting block 6031 and the rectangular mounting plate 6032 to rotate via the sliding rod 6037 and the driving connecting arm 6038, thereby driving the protective top cover 603 to rotate above the circular pressure water tank 602. Finally, the protective top cover 603 presses the enhanced TPR waterproof membrane onto the annular mounting plate 6026.

[0039] Then, by starting the second cylinder 6035, the output shaft of the second cylinder 6035 drives the triangular mounting block 6031 to move, and the triangular mounting block 6031 drives the sliding rod 6037 to slide inside the end of the triangular fixing block 6036. Under the action of the driving connecting arm 6038, the distance between the triangular mounting block 6031 and the triangular fixing block 6036 increases at a uniform speed. At this time, the fixing clamping block 6033 rotates inward under the action of the axis between it and the rectangular mounting plate 6032, thereby pressing the tested enhanced TPR waterproof membrane and the annular mounting plate 6026 through the protective top cover 603. Because the enhanced TPR material has the softness of rubber, the tested enhanced TPR waterproof membrane can form a closed space with the inside of the circular pressure water tank 602.

[0040] By starting the heating platform 601 to heat the water in the circular pressure water tank 602, the water in the circular pressure water tank 602 is heated to become water vapor and rises, and the water vapor heats the tested enhanced TPR waterproof membrane, thereby putting the enhanced TPR waterproof membrane in a high-temperature test environment, and then starting the circular pressure water tank 602 to pressurize the water inside. Under the action of pressure, the water in the circular pressure water tank 602 is sprayed upward toward the enhanced TPR waterproof membrane and acts on the enhanced TPR waterproof membrane, finally achieving a high-temperature waterproof pressure test on the enhanced TPR waterproof membrane. After the test is completed, by observing whether the enhanced TPR waterproof membrane has leaks, breaks, etc., the waterproof and fatigue resistance performance of the enhanced TPR waterproof membrane in a high-temperature environment can be judged.

[0041] In one embodiment, for the above-mentioned pre-cooling and preheating conveying mechanism 8, the pre-cooling and preheating conveying mechanism 8 includes an air compressor 801 arranged at one end of the middle part of the top of the workbench 1, and a vortex tube 802 is arranged at the top of the air compressor 801. Both ends of the vortex tube 802 are provided with an exhaust pipe network 803, and one end of the top side of the exhaust pipe network 803 is provided with an exhaust valve 804. The pre-cooling and preheating conveying mechanism 8 also includes a conveying rack 805 symmetrically arranged on both sides of the middle part of the top of the workbench 1, and the tops of both sides of the conveying rack 805 are penetrated by the exhaust pipe network 803, and the top of one side of the conveying rack 805 is penetrated by a plurality of linearly arranged conveying driven shafts 806 (in addition, in specific applications, the conveying driven shaft 806 is connected to the conveying rack 805 through a bearing), and the outer side of the conveying driven shaft 806 is provided with a conveying Belt 807, a transmission driven wheel 808 is sleeved on the outer side of one end of the transmission driven shaft 806 located at one end of the conveyor belt 807, and the transmission driven wheel 808 is connected to the transmission drive wheel 810 through a transmission belt 809. A transmission drive shaft 811 is provided through the middle of the transmission drive wheel 810, and a protective shell 812 is provided at one end of the transmission drive shaft 811 (in addition, in specific applications, the transmission drive shaft 811 and the protective shell 812 are connected by a bearing), and the other end of the transmission drive shaft 811 is connected to a transmission drive motor 813 (in addition, in specific applications, the transmission drive motor 813 is set as a servo motor), so as to ensure that the temperature of the waterproof membrane has been stabilized within the predetermined test temperature range before being conveyed to the low-temperature fatigue resistance test mechanism 4 and the high-temperature fatigue resistance test mechanism 6, so as to better carry out subsequent fatigue resistance performance tests.

[0042] In addition, it should be noted that the vortex tube 802 includes a nozzle, a vortex chamber, a separation orifice plate and hot and cold end pipes. Compressed air is introduced into the air inlet pipe of the vortex tube 802 through the air compressor 801. The gas will expand in the nozzle and absorb heat to the outside as positive work. Then, it enters the vortex chamber along the tangent of the tube at an extremely high speed and rotates at high speed in the chamber. During the process of entering the heat pipe, the gas rotates along the tube wall and the high-speed friction with the tube wall causes the temperature to rise. Part of the gas will be discharged from the hot end of the vortex tube; the remaining gas will return at a lower speed through the center of the rotating airflow entering the heat pipe. When passing through the nozzle area, heat exchange will occur due to the expansion of the compressed air at the inlet, causing the temperature to gradually decrease to form a cold airflow, which is discharged from the cold end of the vortex tube, thereby generating a cold airflow and a hot airflow at both ends of the vortex tube, pre-cooling one end of the vortex tube and preheating the other end of the vortex tube. This is a prior art and will not be elaborated here.

[0043] The working principle of the pre-cooling and pre-heating conveying mechanism 8 is as follows: first, the air compressor 801 is started, and the compressed air passes through the vortex tube 802. A low-temperature airflow is generated from the cold end of the vortex tube 802 and enters the exhaust pipe network 803 connected to the cold end. The exhaust pipe network 803 cools the conveyor belt 807. A high-temperature airflow is generated from the hot end of the vortex tube 802 and enters the exhaust pipe network 803 connected to the hot end. The exhaust pipe network 803 heats the conveyor belt 807.

[0044] When the enhanced TPR waterproof membrane is tested in the low-temperature fatigue resistance test mechanism 4, the waterproof membrane is taken out from the low-temperature fatigue resistance test mechanism 4 by starting the mechanical arm 7 and placed on the conveying rack 805 connected to the hot end of the vortex tube 802. Then the conveying drive motor 813 is started to drive the conveying drive wheel 810 to rotate through the conveying drive shaft 811, and the conveying drive wheel 810 drives the conveying driven wheel 808 to rotate through the conveying belt 809, so that the conveying driven wheel 808 drives the conveyor belt 807 to rotate through the connected conveying driven shaft 806, and then with the auxiliary rotation of the other conveying driven shafts 806 located at the same end, the conveyor belt 807 moves at a uniform speed, and heat exchange occurs with the waterproof membrane during the movement, so as to preheat the waterproof membrane. When the waterproof membrane is transported to the vicinity of the high-temperature fatigue resistance test mechanism 6 by the conveyor belt 807, the waterproof membrane is taken off by the mechanical arm 7 and sent to the high-temperature fatigue resistance test mechanism 6 for high-temperature fatigue resistance test.

[0045] After the enhanced TPR waterproof membrane is tested in the high-temperature fatigue resistance test mechanism 6, the waterproof membrane is taken out from the high-temperature fatigue resistance test mechanism 6 by starting the robotic arm 7 and placed on the conveying rack 805 connected to the cold end of the vortex tube 802. Then the conveying drive motor 813 is started to drive the conveying drive wheel 810 to rotate through the conveying drive shaft 811, and the conveying drive wheel 810 drives the conveying driven wheel 808 to rotate through the conveying belt 809, so that the conveying driven wheel 808 drives the conveyor belt 807 to rotate through the connected conveying driven shaft 806, and then with the auxiliary rotation of other conveying driven shafts 806 located at the same end, the conveyor belt 807 moves at a uniform speed, and heat exchange occurs with the waterproof membrane during the movement, and the waterproof membrane is pre-cooled. When the waterproof membrane is transported to the vicinity of the low-temperature fatigue resistance test mechanism 4 by the conveyor belt 807, the waterproof membrane is taken off by the robotic arm 7 and sent to the low-temperature fatigue resistance test mechanism 4 for low-temperature fatigue resistance test.

[0046] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0047] In actual application, first, the robot arm 7 is started through the control console 2, and the enhanced TPR waterproof membrane to be tested is placed in the low-temperature fatigue resistance test mechanism 4 (the working principle of the low-temperature fatigue resistance test mechanism 4 is as described above) to carry out a low-temperature fatigue resistance test. After the test is completed, the enhanced TPR waterproof membrane is taken out from the low-temperature fatigue resistance test mechanism 4 by the robot arm 7, and placed in the pre-cooling and preheating conveying mechanism 8 (the working principle of the pre-cooling and preheating conveying mechanism 8 is as described above) for preheating treatment. When the waterproof membrane is transported to the vicinity of the high-temperature fatigue resistance test mechanism 6, the waterproof membrane is taken down by the robot arm 7 and sent to the high-temperature fatigue resistance test mechanism 6 (the working principle of the high-temperature fatigue resistance test mechanism 6 is as described above) for a high-temperature fatigue resistance test. At this point, a round of fatigue resistance performance evaluation of the enhanced TPR waterproof membrane under the temperature difference from low temperature to high temperature is carried out; after the test is completed, the mechanical arm is used again to The robotic arm 7 takes the enhanced TPR waterproof membrane out of the high-temperature fatigue resistance testing mechanism 6 and places it into the pre-cooling and preheating conveying mechanism 8 for pre-cooling treatment. When the waterproof membrane is transported to the vicinity of the low-temperature fatigue resistance testing mechanism 4, the robotic arm 7 takes the waterproof membrane off and places it into the low-temperature fatigue resistance testing mechanism 4 to repeat the low-temperature fatigue resistance test. Thus, a round of fatigue resistance performance evaluation of the enhanced TPR waterproof membrane under the temperature difference change from low temperature to high temperature is carried out; by repeatedly testing the enhanced TPR waterproof membrane alternately between the low-temperature fatigue resistance testing mechanism 4 and the high-temperature fatigue resistance testing mechanism 6, the accelerated fatigue of the enhanced TPR waterproof membrane is achieved through cooperation, which truly simulates the working conditions with large temperature differences such as from low temperature to high temperature or from high temperature to low temperature that the enhanced TPR waterproof membrane may face during actual use, and can more comprehensively evaluate the fatigue resistance performance of the enhanced TPR waterproof membrane.

[0048] In summary, with the help of the above technical scheme of the present invention, the bending and pressure tests of the enhanced TPR waterproof membrane can be carried out under low temperature and high temperature conditions respectively, and the complex use environment that the enhanced TPR waterproof membrane may face in areas with large temperature differences is truly simulated, thereby simulating the working conditions with large temperature differences such as from low temperature to high temperature or from high temperature to low temperature that the enhanced TPR waterproof membrane may face during actual use, and testing the influence of temperature difference changes on the fatigue resistance of the enhanced TPR waterproof membrane, providing a reliable reference for the application of the enhanced TPR waterproof membrane under extreme climatic conditions. At the same time, by setting pre-cooling and pre- The heat transfer mechanism 8 can preheat or precool the waterproof membrane before the test, so that the temperature of the waterproof membrane can be controlled to within the predetermined test temperature range before being transferred to the low-temperature fatigue resistance test mechanism 4 and the high-temperature fatigue resistance test mechanism 6. Then, through the cooperation of various mechanisms, the enhanced TPR waterproof membrane can be subjected to accelerated fatigue testing to verify its service life and more comprehensively evaluate the fatigue resistance of the enhanced TPR waterproof membrane. By setting up the low-temperature fatigue resistance test mechanism 4, the actual night temperature of the polar continental climate area can be simulated, and the test temperature can be controlled at a low temperature to more realistically simulate the actual Actual use conditions, at the same time, repeated bending loads are applied to the waterproof membrane, and the enhanced TPR waterproof membrane can be bent at low temperature, thereby simulating the fatigue process of the enhanced TPR waterproof membrane subjected to repeated bending stress during use. In addition, through the low-temperature fatigue test, the deformation degree and damage degree of the enhanced TPR waterproof membrane under different low-temperature conditions in multiple bending cycles can be monitored in real time to evaluate the fatigue resistance of the enhanced TPR waterproof membrane at low temperatures; by setting up a high-temperature fatigue test mechanism 6, the actual daytime ambient temperature of the polar continental climate region is simulated, and the test temperature is set to Under high temperature conditions, an extrusion load is applied to the waterproof membrane to simulate the high-temperature extrusion stress that the enhanced TPR waterproof membrane may encounter during actual use. In addition, while applying the extrusion load, water is sprayed upward onto the enhanced TPR waterproof membrane. By observing whether the enhanced TPR waterproof membrane leaks or is broken, the waterproof performance of the enhanced TPR waterproof membrane under high temperature is evaluated. At the same time, by adjusting the temperature, the deformation degree of the enhanced TPR waterproof membrane under different high temperature conditions can be observed, the deformation and water seepage under different cycles can be recorded, and the durability of the enhanced TPR waterproof membrane can be judged.
