Description

Technical Field

[0001] This invention mainly relates to the technical field of abrasion resistance testing of building materials, specifically abrasion resistance testing equipment for building materials. Background Technology

[0002] With the continuous development of the construction industry, waterproofing materials are key materials for ensuring the waterproofing performance of buildings. Therefore, the demand for testing the wear resistance of waterproofing materials is also increasing. The quality of their wear resistance directly affects the service life and overall quality of buildings.

[0003] A prior art device for testing the abrasion resistance of waterproof building materials includes a base plate. The upper end of the base plate is equipped with a power device, an adjustment device, a friction device, a limiting component, and a clamping device. The adjustment device is located above the power device, which is connected to the friction device. The limiting component is located on both sides of the friction device. A counterweight component is installed inside the friction device, and the clamping device is located outside the limiting component. Four support legs are fixedly connected to the lower end of the base plate, evenly distributed at the four corners of the lower end. A tensioning device is also provided at the lower end of the base plate.

[0004] While the aforementioned technologies eliminate the need for hand-held grinding wheels to polish the surface of waterproof membranes, reducing labor intensity and improving testing accuracy, linear reciprocating friction cannot effectively simulate the friction that waterproof materials may experience at different angles and directions. For example, waterproof materials on building facades may be subjected to oblique friction from wind-carried debris, but reciprocating linear friction testing equipment can only perform linear friction testing in a single direction, failing to comprehensively assess the wear resistance of waterproof materials under various actual working conditions. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a wear resistance testing device for building materials to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The two pressure plates are located in the placement groove and are connected to the bottom of the groove by screws. Waterproof material is placed in the placement groove, and the two pressure plates press down on the upper surfaces of the two sides of the waterproof material. The testing mechanism is located above the disc and consists of a frame, a reciprocating assembly, and a swing assembly.

[0012] Specifically, in this technical solution, each set of swing components includes a rotating shaft. The bottom end of the rotating shaft is rotatably connected to the upper surface of the worktable. A turntable is fixedly sleeved on the outer wall of the rotating shaft.

The telescopic end of the second electric telescopic rod passes through the crossbar and is fixed to the friction head with a screw. The friction head is in contact with the upper surface of the waterproof material.

[0013] Specifically, in this technical solution, a shaft is rotatably mounted on the upper surface of the L-shaped frame plate near the side plate. A second gear is fixedly sleeved on the outer wall of the shaft. A rack is meshed on the tooth surface of the second gear away from the rotating shaft. A horizontal plate is provided on the outer wall of the rack. A mounting block is fixed on one long side of the lower surface of the horizontal plate. The bottom end of the mounting block is fixedly connected to the top end of the movable block in the reciprocating assembly.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] It should be noted that all electrical components in this device are controlled by an external controller, and a box can be built above the workbench 1. The box is equipped with a refrigeration unit and a heating device. The refrigeration unit is connected to the evaporator inside the box through pipes. The evaporator evaporates the low-temperature refrigerant and absorbs heat, thereby reducing the temperature inside the box. The temperature sensor monitors the temperature inside the box in real time and feeds the data back to the control system. The control system automatically adjusts the working intensity of the refrigeration unit according to the preset low temperature value, so that the temperature inside the box is accurately maintained within the set low temperature range, such as -20℃ to 0℃, simulating the use environment of waterproof material 4 in cold winter regions.

[0031] The heating device uses electric heating wires, which are evenly distributed around the inner wall of the low-temperature chamber. When energized, the heating wires generate heat, raising the temperature inside the chamber. Similarly, a temperature sensor monitors the temperature inside the chamber in real time. The control system adjusts the power of the heating wires according to a preset high-temperature value, stabilizing the temperature inside the chamber within the set high-temperature range, such as 50℃ to 80℃. This simulates the high-temperature environment of the waterproof material 4 in hot summer regions or on a roof exposed to direct sunlight, enabling wear resistance testing of the waterproof material 4 under different temperature conditions.

[0032] In this embodiment, please refer to Figures 1-5 As shown, the abrasion resistance testing equipment for building materials includes a workbench 1, a disc 2, two pressure plates 3, a friction plate 9, a friction head 10, and a testing mechanism 5. The disc 2 is located above the workbench 1, and a placement groove 201 is formed on the upper surface of the disc 2. The two pressure plates 3 are located in the placement groove 201 and are connected to the bottom of the groove with screws. Waterproof material 4 is placed in the placement groove 201, and the two pressure plates 3 press down on the upper surfaces of the two sides of the waterproof material 4. A movable channel 101 is formed on the workbench 1, and a movable block 203 is slidably arranged in the movable channel 101. A drive motor 206 is fixed to the lower surface of the movable block 203 with screws. The output end of the drive motor 206 passes through the movable block 203 and is fixedly connected to the disc 2 through a flange. Sliding grooves 1011 are formed on both sides of the movable channel 101. Both sides of the outer wall of the worktable 3 are integrally provided with sliders 2031. The two sliders 2031 are respectively located in the corresponding slide grooves 1011 and are slidably connected. A hydraulic cylinder 204 is installed on one side of the outer wall of the worktable 1 by screws. The telescopic end of the hydraulic cylinder 204 passes into the moving through groove 101 and is fixed with screws on the outer wall of the moving block 203. Multiple balls 202 are evenly embedded in the lower surface of the disc 2. The bottom outer wall of the multiple balls 202 is in contact with the upper surface of the worktable 1 and is slidably connected. The detection mechanism 5 is located above the disc 2. The detection mechanism 5 consists of a frame 6, a reciprocating assembly 7 and a swing assembly 8. The friction plate 9 is installed on the reciprocating assembly 7 and the friction head 10 is installed on the swing assembly 8. The friction plate 9 and the friction head 10 are made of wear-resistant material, and the bottom outer wall of the friction plate 9 and the friction head 10 are textured.

[0033] The frame 6 includes a vertical plate 601 and two L-shaped frame plates 603. The vertical plate 601 is fixed to the short side of one side of the upper surface of the workbench 1 by screws. Side plates 602 are symmetrically fixed to the outer wall of the vertical plate 601. The two L-shaped frame plates 603 are symmetrically arranged on the long sides of the upper surface of the workbench 1. One end of the two L-shaped frame plates 603 is fixedly connected to the outer wall of the side plate 602 respectively. The reciprocating assembly 7 is located in the two side plates 602. The reciprocating assembly 7 is used to perform reciprocating motion to perform compound friction on the surface of the waterproof material 4 following the rotation of the disc 2. There are two sets of swinging assembly 8. Each set of swinging assembly 8 is installed on the L-shaped frame plate 603. Each set of swinging assembly 8 is connected to the reciprocating assembly 7. The swinging assembly 8 is used to further enrich the angle and mode of friction on the basis of compound friction.

[0034] When conducting abrasion resistance testing on building materials such as waterproof material 4, the staff activates the hydraulic cylinder 204 through the controller, causing the telescopic end of the hydraulic cylinder 204 to retract, which drives the moving block 203 to slide along the moving through groove 101. At this time, the drive motor 206 and the disc 2 connected to the moving block 203 also move accordingly, making it convenient for the staff to place the waterproof material 4 to be tested into the placement groove 201 of the disc 2. The shape of the waterproof material 4 is cut to match the placement groove 201. After the waterproof material 4 is placed flat into the placement groove 201, two pressure plates 3 are used to press on the upper surfaces of both sides of the waterproof material 4 respectively, and the pressure plates 3 are fixed to the bottom of the groove with screws to ensure that the waterproof material 4 will not be displaced during the testing process, thus completing the sample installation.

[0035] Next, the hydraulic cylinder 204 is started again, causing the telescopic end of the hydraulic cylinder 204 to extend, pushing the moving block 203 and the disc 2 back to the initial detection position. Then, the first electric telescopic rod 710 of the reciprocating assembly 7 and the second electric telescopic rod 803 of the swing assembly 8 are started respectively, controlling the friction plate 9 and the friction head 10 to move down until they contact the surface of the waterproof material 4. Next, the drive motor 206 is started, and its output end drives the disc 2 to start reciprocating rotation. The balls 202 evenly embedded in the lower surface of the disc 2 roll and connect with the surface of the worktable 1, reducing the friction force when the disc 2 rotates and ensuring the stability of the rotation. As the disc 2 rotates, the inner teeth 205 of the outer ring wall of the disc 2 will drive the reciprocating assembly 7 to move, so that the friction plate 9 reciprocates against the surface of the waterproof material 4 to achieve compound friction.

[0036] During the reciprocating component 7, it will also drive the two sets of swing components 8 to move, so that the friction head 10 swings on the surface of the waterproof material 4. Based on the compound friction, the angle and method of friction are further enriched. After the test is completed, the drive motor 206 and various electric telescopic rods and other equipment components are turned off, the hydraulic cylinder 204 is started again, the disc 2 is moved to a convenient position, the screws on the pressure plate 3 are loosened, the tested waterproof material 4 sample is taken out, a new sample is replaced, and the above operation process is repeated for the next test.

[0037] By combining the design of the rotating disk 2, the reciprocating motion of the friction plate 9, and the swing component 8, a variety of complex actual friction scenarios can be simulated. The reciprocating component 7 can follow the rotation of the disk 2 to perform reciprocating motion and perform linear reciprocating friction on the surface of the waterproof material 4. The swing component 8 further enriches the angle and mode of friction on the basis of composite friction, so that the friction head 10 can rub the waterproof material 4 in different directions, thereby more closely resembling the complex working conditions that the waterproof material 4 on the building facade may be subjected to, such as the oblique friction of wind-carried debris, and comprehensively evaluating the wear resistance of the waterproof material 4.

[0038] Furthermore, the test position of the disc 2 can be adjusted so that the placement slot 201 on the disc 2 is fully exposed in the unobstructed operating space. Operators can easily put the waterproof material 4 into the placement slot 201, or take out the tested material by loosening the screws of the pressure plate 3, thus optimizing the convenience of loading and unloading the waterproof material 4.

[0039] Please see Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the reciprocating assembly 7 includes a lead screw 708 and a drive shaft 705. One end of the lead screw 708 is fixed to a rotating shaft 707. The rotating shaft 707 and the drive shaft 705 are connected via a magnetic coupler 706, which is fixed between two side plates 602. A movable block 709 is sleeved on the lead screw 708. A first electric telescopic rod 710 is screwed to the lower surface of the movable block 709. The telescopic end of the first electric telescopic rod 710 is screwed to a friction plate 9. The lower surface of the 9th shaft is in contact with the upper surface of the waterproof material 4. A vertical bevel gear 704 is fixedly sleeved on the outer wall of the drive shaft 705. A horizontal bevel gear 703 is meshed with the lower tooth surface of the vertical bevel gear 704. A vertical shaft 702 is fixedly inserted through the center of the horizontal bevel gear 703. A first gear 701 is fixedly sleeved on the outer wall of the vertical shaft 702 below the horizontal bevel gear 703. An inner tooth 205 is provided on the outer ring wall of the disc 2. The tooth surface of the first gear 701 meshes with the inner tooth 205.

[0040] Both sides of the movable block 709 are fixed with horizontal limiting rods 7091. The ends of the two limiting rods 7091 are embedded with abutment beads 7092. The outer walls of the two abutment beads 7092 are in contact with the corresponding side plates 602 and are in a rolling connection. One end of the drive shaft 705 is rotatably connected to the outer wall of the vertical plate 601. The inner side of the two side plates 602 away from the vertical plate 601 is fitted with baffles 6021 by screws. The other end of the lead screw 708 is rotatably connected to the outer wall of the baffles 6021.

[0041] When the disk 2 reciprocates, the inner teeth 205 on the outer ring wall of the disk 2 drive the first gear 701, which meshes with it, to rotate. The first gear 701 drives the horizontal bevel gear 703 to rotate via the vertical shaft 702, which in turn causes the vertical bevel gear 704, which meshes with the horizontal bevel gear 703, to rotate. The vertical bevel gear 704 then drives the transmission shaft 705 to rotate. The transmission shaft 705 drives the rotating shaft 707 to rotate via the magnetic coupler 706. The rotating shaft 707 drives the lead screw 708 to rotate, causing the sleeved movable block 709 to move horizontally along the lead screw 708. The limiting rods 7091 on both sides of the movable block 709... The abutment bead 7092 at its end is rolled to the side plate 602 to ensure the straightness of the movement of the movable block 709. The moving movable block 709 drives the friction plate 9 to move through the first electric telescopic rod 710. The friction plate 9 performs reciprocating friction on the surface of the waterproof material 4. At this time, the surface of the waterproof material 4 not only has to bear the circumferential friction caused by rotation, but also the linear friction generated by the reciprocating motion of the friction plate 9. This is closer to the multi-directional and compound friction situation that the waterproof material 4 may face in actual use, and can more comprehensively test the comprehensive wear resistance of the waterproof material 4 in complex friction environment.

[0042] Please see Figures 5-7 As shown, each set of swing components 8 includes a rotating shaft 801. The bottom end of the rotating shaft 801 is rotatably connected to the upper surface of the worktable 1. A turntable 802 is fixedly sleeved on the outer wall of the rotating shaft 801. A crossbar 8021 is fixed on the outer wall of the turntable 802. A second electric telescopic rod 803 is screwed onto the upper surface of the end of the crossbar 8021 away from the turntable 802. The telescopic end of the second electric telescopic rod 803 passes through the crossbar 8021 and is screwed to the friction head 10. The friction head 10 is in contact with the upper surface of the waterproof material 4.

[0043] A shaft 804 is rotatably mounted on the upper surface of the L-shaped frame plate 603 near the side plate 602. A second gear 8041 is fixedly sleeved on the outer wall of the shaft 804. A rack 8061 is meshed on the tooth surface of the second gear 8041 away from the rotating shaft 801. A horizontal plate 806 is provided on the outer wall of the rack 8061. A mounting block 8062 is fixed on one long side of the lower surface of the horizontal plate 806. The bottom end of the mounting block 8062 is fixedly connected to the top end of the movable block 709 provided in the reciprocating assembly 7. The lower surface of the horizontal plate 806 is in contact with the top end of the side plate 602 and is slidably connected. The top end of the rotating shaft 801 extends through the upper surface of the L-shaped frame plate 603 to the outside. A transmission wheel 805 is fixedly sleeved on the top of the outer wall of the shaft 804 and the top of the outer wall of the rotating shaft 801. The two transmission wheels 805 are connected by a transmission chain 8051.

[0044] During the movement of the movable block 709, the movable block 709 drives the horizontal plate 806 and the rack 8061 to move via the mounting block 8062. The rack 8061 meshes with the second gear 8041, causing the second gear 8041 to rotate. This, in turn, drives the transmission wheel 805 connected to it to rotate via the shaft 804. Under the action of the transmission chain 8051, the transmission wheel 805 on the shaft 804 drives the transmission wheel 805 at the top of the rotating shaft 801 to rotate, causing the rotating shaft 801 and the turntable 802 fixed on the rotating shaft 801 to rotate. The turntable 802 drives the crossbar 8021 and the second electric telescopic rod 803 to swing in an arc, thereby controlling the friction head 10 to swing on the surface of the waterproof material 4. Based on the compound friction, the angle and mode of friction are further enriched. The two work together to create extremely complex and realistic friction conditions, such as simulating the all-round and multi-angle friction faced by the waterproof material 4 under the combined action of strong winds, vibrations and other factors.

[0045] The working principle of this invention is as follows:

[0046] When conducting abrasion resistance testing on building materials such as waterproof material 4, the staff activates the hydraulic cylinder 204 through the controller, causing the telescopic end of the hydraulic cylinder 204 to retract, which drives the moving block 203 to slide along the moving through groove 101. At this time, the drive motor 206 and the disc 2 connected to the moving block 203 also move accordingly, making it convenient for the staff to place the waterproof material 4 to be tested into the placement groove 201 of the disc 2. The shape of the waterproof material 4 is cut to match the placement groove 201. After the waterproof material 4 is placed flat into the placement groove 201, two pressure plates 3 are used to press on the upper surfaces of both sides of the waterproof material 4 respectively, and the pressure plates 3 are fixed to the bottom of the groove with screws to ensure that the waterproof material 4 will not be displaced during the testing process, thus completing the sample installation.

[0047] Next, the hydraulic cylinder 204 is activated again, extending its telescopic end to push the moving block 203 and the disc 2 back to the initial detection position. Then, the first electric telescopic rod 710 of the reciprocating assembly 7 and the second electric telescopic rod 803 of the swing assembly 8 are activated respectively, controlling the friction plate 9 and the friction head 10 to move down until they contact the surface of the waterproof material 4. Next, the drive motor 206 is activated, and its output end drives the disc 2 to begin reciprocating rotation. The inner teeth 205 on the outer ring wall of the disc 2 drive the first gear 701, which meshes with it, to rotate. The first gear 701 drives the horizontal bevel gear 703 to rotate through the vertical shaft 702, which in turn causes the vertical bevel gear 704, which meshes with the horizontal bevel gear 703, to rotate. The vertical bevel gear 704 then drives the transmission shaft 705 to rotate, and the transmission shaft 705 is magnetically coupled. The device 706 drives the rotating shaft 707 to rotate, and the rotating shaft 707 drives the lead screw 708 to rotate, causing the sleeved movable block 709 to move horizontally along the lead screw 708. The abutment beads 7092 at the ends of the limiting rods 7091 on both sides of the movable block 709 are rolledly connected to the side plate 602 to ensure the straightness of the movement of the movable block 709. The moving movable block 709 drives the friction plate 9 to move through the first electric telescopic rod 710. The friction plate 9 performs reciprocating friction on the surface of the waterproof material 4. At this time, the surface of the waterproof material 4 must not only bear the circumferential friction caused by rotation, but also bear the linear friction generated by the reciprocating motion of the friction plate 9. This is closer to the multi-directional and composite friction situation that the waterproof material 4 may face in actual use, and can more comprehensively test the comprehensive wear resistance of the waterproof material 4 in complex friction environment.

[0048] During the movement of the movable block 709, the movable block 709 drives the horizontal plate 806 and the rack 8061 to move through the mounting block 8062. The rack 8061 meshes with the second gear 8041, causing the second gear 8041 to rotate. This, in turn, drives the transmission wheel 805 connected to it to rotate through the shaft 804. Under the action of the transmission chain 8051, the transmission wheel 805 on the shaft 804 drives the transmission wheel 805 at the top of the rotating shaft 801 to rotate, causing the rotating shaft 801 and the turntable 802 fixed on the rotating shaft 801 to rotate. The turntable 802 drives the crossbar 8021 and the second electric telescopic rod 803 to swing in an arc shape, thereby controlling the friction head 10 to swing on the surface of the waterproof material 4. Based on the composite friction, the angle and mode of friction are further enriched.
