Description

Technical Field

[0001] This invention relates to the field of rubber waterstop performance testing technology, specifically to a device for testing the puncture performance of rubber waterstops. Background Technology

[0002] Rubber waterstops and waterproof rubber sheets are made primarily from natural rubber and various synthetic rubbers, with added additives and fillers. They are produced through plasticizing, mixing, and molding, resulting in a wide variety of types and specifications, including bridge-type, mountain-type, P-type, U-type, Z-type, B-type, T-type, H-type, E-type, and Q-type. They are manufactured using natural rubber or various synthetic rubbers as the main raw materials, with added additives and fillers, through plasticizing, mixing, calendering, and vulcanization processes. Based on application, they can be classified into embedded rubber waterstops and back-attached rubber waterstops. This waterstop material possesses good elasticity, wear resistance, aging resistance, and tear resistance. It has strong adaptability to deformation and good waterproof performance. Rubber waterstops are widely used in construction and water conservancy projects to prevent water seepage and leakage.

[0003] In the existing technology, the performance testing of rubber waterstops mainly focuses on tensile strength and tear strength, and there is a lack of related devices for testing the puncture resistance of waterstops. This makes it impossible to simulate the puncture effect of sharp objects or high-pressure water on waterstops in actual working environments, resulting in an incomplete performance test of waterstops. Summary of the Invention

[0014] Preferably, a PLC control panel is fixedly installed on the outer surface of the machine body, a detection platform is fixedly installed on the top surface of the machine body, and a cutting platform is provided on the inner side of the fourth mounting base.

[0015] Working principle: When using this device, it can be placed in a designated position, and the rubber waterstop to be tested can be extended sequentially to the positioning mechanism, calendering mechanism, pressure detection mechanism, puncture detection mechanism, guiding mechanism and cutting mechanism. The lifting motor is turned on, which drives the threaded cylinder to rotate. The threaded cylinder drives the threaded rod to extend, and the threaded rod pushes the first mounting frame to move down. The first mounting frame drives the pressure roller to move down, pressing the rubber waterstop onto the top surface of the rotating roller. The first electric push rod is turned on, which pushes the limit plate to move, thereby limiting the rubber waterstop. Turn on the second electric actuator, which pushes the third mounting frame to move. The third mounting frame causes the inner output roller to move down, pressing the rubber waterstop between the two output rollers. Turn on the rotating motor, which drives the output roller to rotate, thereby conveying the rubber waterstop. The first hydraulic rod is activated, which pushes the mounting plate downward. The mounting plate then moves the monitoring head downward. The monitoring head applies rated pressure to the rubber waterstop to test its compressive strength. The water pump is activated, drawing water from the tank into the distribution pipe, which then transmits the water to the nozzle. The nozzle is activated, spraying a water jet onto the surface of the rubber waterstop, causing the contact roller to contact the rubber waterstop. When the water jet contacts the rubber waterstop, any water seepage will penetrate the seepage layer. The water immersion sensor can detect the seepage, thus detecting the puncture and waterproof performance of the rubber waterstop. Turn on the hot air blower, and the hot air blows hot air onto the surface of the rubber waterstop, which can dry the surface of the rubber waterstop. When the output roller rotates, it drives the worm aortic arch through the connecting belt. The worm drives the worm wheel to rotate, the worm wheel drives the connecting rod to rotate, the connecting rod drives the gear to rotate, the gear drives the toothed belt to rotate, the toothed belt drives the rotating block to rotate, and the rotating block drives the hot air blower inside to rotate, which can increase the drying effect of the waterstop. After the test is completed, the rubber waterstop can be extended a certain distance by rotating the output roller, and the second hydraulic rod can be activated. The second hydraulic rod pushes the cutter down, and the cutter can cut the rubber waterstop to facilitate subsequent tensile tests.

[0016] This invention provides a device for testing the puncture performance of rubber waterstops. It has the following beneficial effects: 1. In this invention, a puncture detection mechanism is set up. When testing the rubber waterstop, the rubber waterstop first passes through the pressure detection mechanism to test its impact pressure. Then, the waterstop is extended into the puncture detection mechanism, and a water jet is sprayed through the nozzle to simulate the impact of the waterstop. In this way, the puncture performance of the waterstop can be tested. In addition, the water jet is in contact with the surface of the waterstop, so its waterproof performance can also be tested.

[0017] 2. In this invention, a guide mechanism and a positioning mechanism are respectively set on the top of the machine body, which can ensure stable conveying during the testing of the waterstop and increase the stability during the testing. The cutting mechanism can facilitate the cutting of the waterstop for subsequent tensile testing.

[0018] 3. In this invention, water-absorbing sponges are provided on the outer surfaces of the two output rollers. The water-absorbing sponges can absorb and dry the surface of the waterstop after the puncture test, which prevents the water on the surface of the waterstop from reducing the friction between the waterstop and the clamp during the subsequent tensile test, which would easily cause slippage during the tensile process and affect the test process.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 , Figure 5 and Figure 6This invention provides a puncture performance testing device for rubber waterstops, comprising a body 1, a positioning mechanism 3 fixedly connected to the outer surface of the body 1, a calendering mechanism 4 above the positioning mechanism 3 and fixedly mounted on the outer surface of the body 1, a pressure detection mechanism 5 fixedly mounted on the top surface of the body 1, a puncture detection mechanism 6 inside the body 1, a guide mechanism 7 fixedly mounted on the top surface of the body 1, a cutting mechanism 8 on the side of the guide mechanism 7, and a cutting mechanism 8 inside the puncture detection mechanism 6. Diverter pipe 609, with multiple nozzles 603 mounted on its top surface. A baffle 601 is fixedly mounted on the inner side of the puncture detection mechanism 6. Two telescopic rods 605 are fixedly mounted on the bottom surface of the baffle 601. A second mounting frame 607 is fixedly connected to the bottom end of the telescopic rods 605. A contact roller 608 is rotatably mounted on the inner side of the second mounting frame 607. A water-permeable layer 6081 is provided on the outer side of the contact roller 608. Multiple water immersion sensors 6082 are provided between the water-permeable layer 6081 and the contact roller 608.

[0023] Specifically, the permeable layer 6081 is made of 0.6 cm cotton fabric, which has good water absorption and permeability. When testing the puncture performance of the rubber waterstop, the rubber waterstop can be extended into the interior of the puncture mechanism and come into contact with the surface of the contact roller 608. When the nozzle 603 is turned on, the nozzle 603 sprays a water jet towards the contact roller 608. The water jet contacts the bottom of the waterstop, thus simulating the scenario of the waterstop being impacted by water flow, thereby testing its puncture performance. When the waterstop is punctured by the water jet, water will seep out from the top surface of the waterstop. The seeping water comes into contact with the permeable layer 6081 on the outside of the contact roller 608 and can then penetrate into the permeable layer 6081. The inner side of the nozzle 603 contacts the water immersion sensor 6082. The water immersion sensor 6082 detects the water seepage, which in turn determines the puncture performance of the waterstop. During the puncture test, the nozzle 603 sprays a water jet that contacts the surface of the waterstop. Throughout the process, the water resistance of the waterstop can also be tested, thus enhancing the functionality of the device. The water immersion sensor 6082 used in this device is existing technology. It is based on the principle of liquid conductivity. Under normal conditions, the two probes are insulated by air. When there is water immersion, the probes conduct, and the sensor outputs a dry contact signal, which can detect water immersion information. It is widely used in various fields, so its specific structure and principle will not be described in detail here.

[0024] Please see the appendix Figure 5 and Figure 7 The two telescopic rods 605 are equipped with telescopic springs 6051 inside. The top surface of the second mounting frame 607 is fixedly connected to a pull block 604. The top surface of the pull block 604 is fixedly connected to a pull rope 610. The top end of the pull rope 610 is fixedly connected to a pull ring 606.

[0025] Specifically, the pull ring 606 is located on the outside of the baffle 601 and extends beyond the outside of the baffle 601, and is movably connected to the baffle 601. In actual use, the pull ring 606 can be pulled, which moves the pull rope 610. The pull rope 610 pulls the second mounting frame 607 upward through the pull block 604. The second mounting frame 607 can drive the contact roller 608 upward. When the second mounting frame 607 moves upward, it can drive the telescopic rod 605 to retract. The retraction of the telescopic rod 605 can drive the telescopic spring 6051 to deform inward. At the same time, the telescopic spring 6051 pushes the outer rod of the telescopic rod 605, and the outer rod of the telescopic rod 605 pushes the second mounting frame 607. This ensures that the contact roller 608 contacts the rubber waterstop placed in the puncture detection mechanism 6, thus ensuring the normal progress of the detection.

[0026] Please see the appendix Figure 1 and attached Figure 6 The puncture detection mechanism 6 has two guide rollers 602 installed inside. The bottom surface of the machine body 1 is provided with a water tank 9, which is connected to the inside of the puncture detection mechanism 6. The bottom surface of the machine body 1 is fixedly installed with a water pump 10 through a fixing frame, and the water pump 10 is connected to the water tank 9 through a pipe.

[0027] Specifically, the water pump 10 is also connected to the diversion pipe 609 through a pipe, so that the water pump 10 can be turned on. The water pump 10 can draw water from the inside of the water tank 9 into the inside of the diversion pipe 609 through the pipe. The diversion pipe 609 can deliver water to the inside of the nozzle 603. The puncture detection mechanism 6 is connected to the inside of the water tank 9, so that the water sprayed by the nozzle 603 can flow back into the inside of the water tank 9, which is convenient for the recycling and reuse of the detection water.

[0028] Please see the appendix Figure 3 The positioning mechanism 3 includes a support arm 301, a first electric push rod 302, a limiting plate 303, and a rotating roller 304. The two support arms 301 are fixedly installed on both sides of the machine body 1, the rotating roller 304 is rotatably installed between the two support arms 301, the two limiting plates 303 are movably installed on the outside of the rotating roller 304, the first electric push rod 302 is fixedly installed inside the support arm 301, and the telescopic end of the first electric push rod 302 is connected to the limiting plate 303.

[0029] Specifically, during testing, the rubber waterstop can be placed on the outer surface of the roller 304 and between the two limiting discs 303. At this time, the first electric push rod 302 can be activated, which can push the two limiting discs 303 to move relative to each other. The two limiting discs 303 can limit the two sides of the rubber waterstop placed on the surface of the roller 304, preventing the waterstop from shifting during testing and conveying, and ensuring the stability and directionality of the waterstop during conveying.

[0030] Please see the appendix Figure 3The calendering mechanism 4 includes a first mounting base 407, a lifting motor 401, a threaded cylinder 402, a threaded rod 403, a first guide rod 404, a first mounting frame 405, and a pressure roller 406. The first mounting base 407 is fixedly mounted on the outer surface of the machine body 1. The first mounting frame 405 is disposed on the inner side of the first mounting base 407. The threaded rod 403 is fixedly mounted on the top surface of the first mounting frame 405. The threaded cylinder 402 is sleeved on the outer side of the threaded rod 403, and the threaded cylinder 402 and the threaded rod 403 are connected by threads. The lifting motor 401 is mounted on the top surface of the first mounting base 407, and the output end of the lifting motor 401 is connected to the threaded cylinder 402. The first guide rod 404 is fixedly mounted on the inner surface of the first mounting base 407, and the bottom end of the first guide rod 404 is fixedly connected to the first mounting frame 405.

[0031] Specifically, the threaded cylinder 402 and the threaded rod 403 are connected by threads. When the threaded cylinder 402 rotates and limits the threaded rod 403, the threaded cylinder 402 can drive the threaded rod 403 to extend and retract inside the threaded cylinder 402. When the threaded rod 403 extends and retracts, it can push the first mounting frame 405 to rise and fall inside the first mounting base 407. The rise and fall of the first mounting frame 405 can drive the pressure roller 406 on its inner side to rise and fall. The pressure roller 406 is located directly above the rotating roller 304, which can press the waterstop on the surface of the rotating roller 304. This can further ensure the stability and directionality of the waterstop during delivery. The first guide rod 404 is telescopic. When the first mounting frame 405 rises and falls, it can drive the first guide rod 404 to extend and retract accordingly, which can increase the directionality and stability of the first mounting frame 405 and the pressure roller 406 during rise and fall.

[0032] Please see the appendix Figure 4 The pressure detection mechanism 5 includes a second mounting base 501, a second guide rod 502, a first hydraulic rod 503, a mounting plate 504, and a detection head 505. The second mounting base 501 is fixedly mounted on the top surface of the body 1. The mounting plate 504 is disposed inside the second mounting base 501. The first hydraulic rod 503 is fixedly mounted on the inner surface of the second mounting base 501, and the telescopic end of the first hydraulic rod 503 is connected to the mounting plate 504. The second guide rod 502 is fixedly mounted on the top surface of the mounting plate 504, and the top end of the second guide rod 502 is fixedly connected to the inner surface of the second mounting base 501. The detection head 505 is fixedly mounted on the bottom surface of the mounting plate 504.

[0033] Specifically, during testing, the rubber waterstop can be extended into the inner side of the second mounting base 501 and placed at the bottom of the testing head 505. By activating the first hydraulic rod 503, the first hydraulic rod 503 can push the mounting plate 504 downward, and the mounting plate 504 can drive the monitoring head downward, bringing the monitoring head into contact with the surface of the rubber waterstop, thus testing its compressive strength. The second guide rod 502 is telescopic, so when the mounting plate 504 is raised or lowered, the second guide rod 502 can be raised or lowered accordingly, thereby increasing the stability and directionality of the mounting plate 504 and the testing head 505 during raising and lowering.

[0034] Please see the appendix Figure 8 The guiding mechanism 7 includes a third mounting base 701, a second electric actuator 702, a third guide rod 703, a third mounting frame 704, an output roller 705, and a water-absorbing sponge 706. The third mounting base 701 is fixedly mounted on the top surface of the machine body 1. The third mounting frame 704 is located inside the third mounting base 701. The two output rollers 705 are respectively located inside the third mounting frame 704 and the third mounting base 701. The water-absorbing sponge 706 is fixedly sleeved on the outer surface of the output roller 705. The second electric actuator 702 is fixedly mounted on the top surface of the third mounting base 701 through a fixing bracket, and the telescopic end of the second electric actuator 702 is connected to the third mounting frame 704. The third guide rod 703 is fixedly mounted on the top surface of the third mounting frame 704.

[0035] Specifically, during use, the rubber waterstop can be extended between the two output rollers 705. The second electric actuator 702 is activated, which pushes the third mounting frame 704 downward. The third mounting frame 704 then moves the output rollers 705 on its inner side downward, bringing the two sides of the waterstop into contact with the two output rollers 705. When one of the output rollers 705 rotates, the waterstop can be conveyed to one side, ensuring orderly testing. This allows for testing at different positions of a roll of waterstop, ensuring the accuracy of the testing. The third guide rod 703 is slidably connected to the third mounting base 701. Thus, when the second electric actuator 702 pushes the third mounting frame 704 downward, the third guide rod 703 can slide on the top of the third mounting base 701, thereby increasing the stability and directional accuracy of the third mounting frame 704 during lifting and lowering.

[0036] Please see the appendix Figure 9The machine body 1 has a rotating block 708 inside. A toothed belt 709 is fixedly connected to the bottom surface of the rotating block 708. A hot air blower 710 is fixedly installed inside the rotating block 708. A gear 712 is meshed inside the toothed belt 709. A connecting rod 713 is fixedly connected to the bottom surface of the gear 712. A worm gear 714 is fixedly connected to the top of the connecting rod 713. A worm 715 is meshed on one side of the worm gear 714. A rotating motor 707 is fixedly installed on the outer surface of the third mounting base 701 through a fixing bracket. The output end of the rotating motor 707 is connected to one of the output rollers 705. A connecting belt 716 is connected between the output roller 705 and the worm 715 through a pulley. Sliding wheels 711 are fixedly connected to both sides of the rotating block 708.

[0037] Specifically, after the puncture test, the rubber waterstop is placed between two output rollers 705. The absorbent sponge 706 on the outside of the output rollers 705 can absorb the test water adhering to the surface of the waterstop, thus ensuring the dryness of the rubber waterstop. This prevents water from hindering positioning during subsequent tensile testing, increasing the functionality of the device. When the rotating motor 707 drives the output rollers 705 to rotate, the connecting shaft between the output rollers 705 and the rotating motor 707 can drive the connecting belt 716 to rotate via a pulley. The connecting belt 716 can drive the worm gear 715 to rotate, which in turn drives the worm wheel 714 to rotate. The worm wheel 714 drives the connecting rod 713 to rotate, which in turn drives the gear 712 to rotate. The gear 712 can drive the toothed belt 709 to rotate, which in turn drives the rotating block 708 to rotate, simultaneously driving the hot air blower 710 inside to rotate. The hot air blower 710 and the rotating block 708 are fixedly connected by a flexible material (rubber plate). The hot air blower 710 is circular and has an electric heating wire inside. Therefore, when the hot air blower 710 moves to the arc of the rotating block 708, the rubber plate can deform accordingly, ensuring the stable movement of the hot air blower 710. The top surface of the machine body 1 has an air outlet, which is directly opposite the output roller 705. When the water-absorbing sponge 706 absorbs water, its internal humidity is high. At this time, the hot air blower 710 can be turned on, and the hot air blower 710 can blow hot air towards the output roller 705 to dry the water-absorbing sponge 706, ensuring the drying performance of the water-absorbing sponge 706 on the waterstop. The movement of the hot air blower 710 can increase the drying effect of the water-absorbing sponge 706. The machine body 1 has a sliding groove inside, and the sliding wheel 711 is set inside the sliding groove, which can increase the stability and directionality of the rotating block 708 when rotating.

[0038] Please see the appendix Figure 10The cutting mechanism 8 includes a fourth mounting base 801, a second hydraulic rod 802, a fourth guide rod 803, and a cutter 804. The fourth mounting base 801 is fixedly mounted on the top surface of the machine body 1. The cutter 804 is disposed inside the fourth mounting base 801. The second hydraulic rod 802 is fixedly mounted inside the fourth mounting base 801, and the telescopic end of the second hydraulic rod 802 is fixedly connected to the cutter 804. The fourth guide rod 803 is provided inside the fourth mounting base 801, and the bottom end of the fourth guide rod 803 is fixedly connected to the cutter 804.

[0039] Specifically, during use, after the pressure and puncture performance of the waterstop has been tested, and its tensile performance needs to be tested, the waterstop can be extended to the inside of the fourth mounting base 801 and extended to a specified length.
