Description

Technical Field

[0001] The present invention relates to the technical field of building waterproof board detection, and particularly to a toughness detection test device for building waterproof boards. Background Art

[0002] The toughness detection test device for building waterproof boards is mainly used to test the toughness of waterproof board materials under different conditions to ensure their service performance in building construction.

[0003] The patent with the patent announcement number CN219757886U relates to a toughness detection test device for building waterproof boards, belonging to the technical field of building waterproof board detection, including a base, a protective cover and a building waterproof board body. A box door is inserted and installed on the left side wall of the base. The protective cover and the box door are used to protect the building waterproof board body during detection. A hydraulic rod is arranged on the top surface of the base. In this patent, the clamping plate moves horizontally in the shell through the threaded engagement of the threaded rod and the shell, and the building waterproof board body is fixed through the inner wall of the rear side wall of the clamping plate and the shell. The initial position is measured by a measuring mechanism. The hydraulic rod drives the upper fixing mechanism to move vertically, thereby driving the connecting rod and the measuring plate to move vertically inside the through groove. The deformation of the building waterproof board body is measured by the correspondence between the measuring plate and the scale line, and the curvature of the bending of the building waterproof board body is detected synchronously by a vision camera.

[0004] In the above patent, it has the function of stably fixing the building waterproof board. The building waterproof board body is fixed through the inner wall of the rear side wall of the clamping plate and the shell, ensuring that the building waterproof board does not shift during detection. However, when detecting the EVA waterproof board in the building waterproof board, in order to ensure the integrity of the detection, in addition to applying uniform pressure for toughness testing, the tester also needs to fold the EVA waterproof board to improve the accuracy and integrity of the test data. But due to the fixing method of the fixture, the tester has to frequently adjust the EVA waterproof board, which not only increases the complexity of the operation but also greatly reduces the test efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a toughness detection test device for building waterproof boards, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A toughness detection test device for building waterproof boards, including a test bench, on the top of which a driving device is provided. The output end of the driving device is fixedly installed with a pressure head, and a pressure sensor is arranged inside the driving device, including: a bottom plate fixedly installed on the surface of the test bench, with a chute opened on the bottom plate; a fixed clamp fixedly installed on the top of the bottom plate, with an internally threaded through hole opened on the fixed clamp; a roller sleeved on the chute; a hollow plate fixedly installed on the circumferential surface of the roller; a telescopic plate slidably penetrating through the side of the hollow plate away from the roller; a first spring arranged between the hollow plate and the telescopic plate. The telescopic plate moves to compress the first spring, and the first spring restores to push the telescopic plate to reset to the starting position; a support shaft fixedly penetrating through the surface of the telescopic plate; a movable clamp fixedly installed on the circumferential surface of the support shaft, with an internally threaded through hole opened on the movable clamp. Pushing the movable clamp towards the fixed clamp, the movable clamp drives the support shaft to move synchronously; two screws respectively threadedly connected to the fixed clamp and the movable clamp.

[0007] According to the above technical solution, a sliding frame slidably penetrates through the top of the bottom plate. A second spring is arranged between the fixed clamp and the sliding frame. The sliding frame moves to stretch the second spring, and the second spring restores to pull the sliding frame to reset. The surfaces of the sliding frame and the fixed clamp are in contact.

[0008] According to the above technical solution, the roller moves vertically along the chute. Control the roller to rise to the top along the chute, and then rotate the hollow plate. The hollow plate drives the telescopic plate to rotate synchronously. A round hole is opened on the circumferential surface of the support shaft, and the top of the movable clamp is in contact with the bottom plate.

[0009] According to the above technical solution, a stabilizing device for fixing the movable clamp is arranged on the bottom plate, and an auxiliary device for improving the operation stability is arranged on the stabilizing device; the stabilizing device includes an L-shaped plate, a T-shaped rod, a third spring, a lifting frame, a fourth spring and a roller. The movable clamp is in contact with the T-shaped rod and drives it to move synchronously. The T-shaped rod moves to stretch the third spring. The L-shaped plate is fixedly installed on the top of the bottom plate. The T-shaped rod slidably penetrates through the inner and outer walls of the L-shaped plate. The third spring is arranged between the L-shaped plate and the T-shaped rod. The elastic coefficient of the third spring is less than that of the first spring. The lifting frame is slidably installed on the inner wall of the L-shaped plate. The fourth spring is arranged between the lifting frame and the L-shaped plate. The roller rotatably penetrates through the inner and outer walls of the lifting frame. The top of the L-shaped plate is in contact with the movable clamp, and the T-shaped rod is in contact with the side of the movable clamp away from the roller. When the movable clamp moves towards the fixed clamp, the compressed third spring releases elastic force to push the T-shaped rod to move synchronously towards the movable clamp.

[0010] According to the above technical solution, an adapter plate is fixedly installed on the surface of the L-shaped plate. A long rod is fixedly installed on the side of the adapter plate close to the support shaft. The round hole of the support shaft moves into contact with the long rod, and the long rod provides an additional supporting force for the movable clamping seat through the support shaft.

[0011] According to the above technical solution, the circumferential surface of the roller contacts the top of the movable clamping seat. A spherical surface is formed on the side of the long rod away from the adapter plate. The circumferential surface of the long rod contacts the inner wall of the round hole. The round hole on the support shaft automatically separates from the long rod during movement.

[0012] According to the above technical solution, the auxiliary device includes a fixed frame, a sliding rod, a sleeve plate, a C-shaped rod and a rubber ring. The movement of the sliding rod drives the movement of the C-shaped rod, and the movement of the C-shaped rod drives the movement of the rubber ring. The fixed frame is fixedly installed on the surface of the L-shaped plate. The sliding rod slidably penetrates through the outer side wall of the fixed frame. The sleeve plate is fixedly installed on the surface of the sliding rod. The C-shaped rod is fixedly installed on the circumferential surface of the sliding rod. The rubber ring is fixedly installed on the circumferential surface of the C-shaped rod. The sleeve plate is fixedly connected to the I-shaped rod. The movement of the I-shaped rod drives the movement of the sleeve plate, and the movement of the sleeve plate drives the movement of the sliding rod.

[0013] According to the above technical solution, an elastic sheet is fixedly installed on the top of the inner wall of the fixed frame. The other end of the elastic sheet is fixedly installed with a pressing plate. The circumferential surface of the rubber ring contacts the bottom of the pressing plate. When the rubber ring moves, resistance is generated by the friction at the contact surface between it and the pressing plate.

[0014] The present invention provides a toughness detection test device for building waterproof boards, which has the following beneficial effects: (1) For the toughness detection test device for building waterproof boards, the movable clamping seat resets to straighten the waterproof board. The EVA waterproof board is conveniently fixed through the movable clamping seat, and the EVA waterproof board is automatically straightened after being fixed, ensuring the flatness of the surface of the EVA waterproof board, which helps to improve the reliability of the test results. At the same time, the support shaft drives the movable clamping seat to rotate synchronously, causing the waterproof board to bend along the preset folding line. The flexibility of the movable clamping seat is improved through the roller, effectively saving the time for the tester to fold and fix the EVA waterproof board, and improving the overall efficiency of the test.

[0015] (2) For the toughness detection test device for building waterproof boards, the I-shaped rod provides an auxiliary thrust for the movable clamping seat. By providing an auxiliary thrust for the movable clamping seat through the I-shaped rod, the effort required for the tester to adjust the movable clamping seat is reduced, which helps to ensure the accuracy of the operation. At the same time, the roller exerts a stable pressure on the movable clamping seat. By setting the roller and the long rod, the stability of the movable clamping seat at the starting position is enhanced, ensuring that the movable clamping seat remains in the preset position during the toughness test process.

[0016] (3)The toughness detection test device for the building waterproof board. The sliding rod transfers the support to the I-shaped rod through the sleeve plate, and is fixedly connected to one end of the I-shaped rod through the sleeve plate, further enhancing the stability of the I-shaped rod itself and ensuring the smooth progress of the toughness detection. At the same time, the contact surface friction between the rubber ring and the pressure plate generates resistance. By setting the pressure plate, intermittent resistance is applied to the I-shaped rod to ensure that when the first spring returns, the movable clamping seat will not collide with the L-shaped plate, preventing the screws from loosening due to vibration.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 5, an embodiment of the present invention is: a toughness detection test device for building waterproof boards, including a test bench 1, a driving device 2 is arranged on the top of the test bench 1, a pressure head 3 is fixedly installed at the output end of the driving device 2, and a pressure sensor is arranged inside the driving device 2, including: a bottom plate 4, the bottom plate 4 is fixedly installed on the surface of the test bench 1, and a chute is opened on the bottom plate 4; a fixed clamping seat 5, the fixed clamping seat 5 is fixedly installed on the top of the bottom plate 4, and an internally threaded through hole is opened on the fixed clamping seat 5; a rotating roller 6, the rotating roller 6 is sleeved on the chute; a hollow plate 7, the hollow plate 7 is fixedly installed on the circumferential surface of the rotating roller 6; a telescopic plate 8, the telescopic plate 8 slidably penetrates through one side of the hollow plate 7 away from the rotating roller 6; a first spring 9, the first spring 9 is arranged between the hollow plate 7 and the telescopic plate 8; a support shaft 10, the support shaft 10 is fixedly penetrated through the surface of the telescopic plate 8; a movable clamping seat 11, the movable clamping seat 11 is fixedly installed on the circumferential surface of the support shaft 10, and an internally threaded through hole is opened on the movable clamping seat 11; two screws 12, the two screws 12 are respectively threadedly connected to the fixed clamping seat 5 and the movable clamping seat 11. By means of the movable clamping seat 11, it is convenient to fix the EVA waterproof board, and the EVA waterproof board is automatically straightened after being fixed, ensuring the flatness of the surface of the EVA waterproof board, which helps to improve the reliability of the test results.

[0021] A sliding frame 13 slidably penetrates through the top of the bottom plate 4, and a second spring 14 is arranged between the fixed clamping seat 5 and the sliding frame 13, and the surfaces of the sliding frame 13 and the fixed clamping seat 5 are in contact. By arranging the sliding frame 13, it is ensured that after the movable clamping seat 11 is adjusted, it can be stably maintained at the preset position for testing.

[0022] The rotating roller 6 moves in the vertical direction along the chute, a round hole is opened on the circumferential surface of the support shaft 10, and the movable clamping seat 11 is in contact with the top of the bottom plate 4. By means of the rotating roller 6, the flexibility of the movable clamping seat 11 is improved, effectively saving the time for the tester to fold and fix the EVA waterproof board, and improving the overall efficiency of the test.

[0023] When this embodiment is working, the tester first cuts the EVA waterproof board into a preset size, loosens the screws 12 on the fixed clamping seat 5 and the movable clamping seat 11 with a screwdriver, so that the screws 12 rise along the internal thread through holes to the preset height, inserts one side of the waterproof board into the fixed clamping seat 5, and rotates the screws 12 on the fixed clamping seat 5 in the reverse direction, so that the screws 12 move downward to press the edge of one side of the waterproof board; pushes the movable clamping seat 11 to move towards the fixed clamping seat 5, the movable clamping seat 11 drives the support shaft 10 to move synchronously, the support shaft 10 drives the telescopic plate 8 to move synchronously, the telescopic plate 8 moves to compress the first spring 9. When the movable clamping seat 11 reaches the preset position, inserts the other side of the waterproof board into the movable clamping seat 11, and similarly tightens the screws 12 to press the edge of the other side of the waterproof board; loosens the movable clamping seat 11, and the first spring 9 restores to push the telescopic plate 8 to reset to the starting position. At this time, the movable clamping seat 11 that resets together straightens the waterproof board; starts the driving device 2, the output end of which drives the pressure head 3 to move downward to contact the surface of the waterproof board, and uniformly presses the waterproof board for the toughness detection test. The pressure sensor in the driving device 2 collects data in real time. The EVA waterproof board is conveniently fixed through the movable clamping seat 11, and the EVA waterproof board is automatically straightened after being fixed, ensuring the flatness of the surface of the EVA waterproof board, which helps to improve the reliability of the test results. When it is necessary to fold the EVA waterproof board for testing, after the tester fixes the other side of the waterproof board, controls the roller 6 to rise to the top along the chute, and then rotates the hollow plate 7. The hollow plate 7 drives the telescopic plate 8 to rotate synchronously, the telescopic plate 8 drives the support shaft 10 to rotate synchronously, and the support shaft 10 drives the movable clamping seat 11 to rotate synchronously, so that the waterproof board bends along the preset folding line; when the movable clamping seat 11 rotates to the preset angle, the tester pushes the sliding frame 13 to move away from the fixed clamping seat 5, and the sliding frame 13 moves to stretch the second spring 14. When the sliding frame 13 reaches the preset position, continue to rotate the hollow plate 7 until the movable clamping seat 11 contacts the fixed clamping seat 5, loosen the sliding frame 13, and the second spring 14 restores to pull the sliding frame 13 to reset. The reset sliding frame 13 abuts against the bottom of the movable clamping seat 11, thereby stabilizing the rotated movable clamping seat 11; starts the driving device 2, and the pressure head 3 uniformly presses down to contact the folded part of the waterproof board for the toughness detection test. The flexibility of the movable clamping seat 11 is improved through the roller 6, effectively saving the time for the tester to fold and fix the EVA waterproof board, and improving the overall efficiency of the test.

[0024] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, a stabilizing device for fixing the movable card seat 11 is provided on the bottom plate 4, and an auxiliary device for improving the operation stability is provided on the stabilizing device; the stabilizing device includes an L-shaped plate 151, a shaped rod 152, a third spring 153, a lifting frame 154, a fourth spring 155 and a roller 156. The L-shaped plate 151 is fixedly installed on the top of the bottom plate 4. The shaped rod 152 slides through the inner and outer walls of the L-shaped plate 151. The third spring 153 is arranged between the L-shaped plate 151 and the shaped rod 152. The lifting frame 154 is slidably installed on the inner wall of the L-shaped plate 151. The fourth spring 155 is arranged between the lifting frame 154 and the L-shaped plate 151. The roller 156 rotates through the inner and outer walls of the lifting frame 154. The top of the L-shaped plate 151 contacts the movable card seat 11, and the shaped rod 152 contacts the side of the movable card seat 11 away from the roller 6. An auxiliary thrust is provided for the movable card seat 11 through the shaped rod 152, reducing the effort required for the tester to adjust the movable card seat 11 and helping to ensure the accuracy of the operation.

[0025] A connecting plate 157 is fixedly installed on the surface of the L-shaped plate 151, and a long rod 158 is fixedly installed on the side of the connecting plate 157 close to the support shaft 10. The stability of the movable card seat 11 in the starting position is enhanced by setting the roller 156 and the long rod 158, ensuring that the movable card seat 11 remains in the preset position during the toughness test.

[0026] The circumferential surface of the roller 156 contacts the top of the movable card seat 11. A spherical surface is provided on the side of the long rod 158 away from the connecting plate 157, and the circumferential surface of the long rod 158 contacts the inner wall of the round hole. By providing the spherical surface, it is ensured that the long rod 158 can pass through the round hole smoothly, guaranteeing the stability of the contact.

[0027] The auxiliary device includes a fixed frame 161, a sliding rod 162, a sleeve plate 163, a C-shaped rod 164 and a rubber ring 165. The fixed frame 161 is fixedly installed on the surface of the L-shaped plate 151. The sliding rod 162 slides through the outer wall of the fixed frame 161. The sleeve plate 163 is fixedly installed on the surface of the sliding rod 162. The C-shaped rod 164 is fixedly installed on the circumferential surface of the sliding rod 162. The rubber ring 165 is fixedly installed on the circumferential surface of the C-shaped rod 164. The sleeve plate 163 is fixedly connected to the shaped rod 152. By fixedly connecting the sleeve plate 163 to one end of the shaped rod 152, the stability of the shaped rod 152 itself is further enhanced, ensuring the smooth progress of the toughness test.

[0028] An elastic piece 166 is fixedly installed on the top of the inner wall of the fixed frame 161, and a pressing plate 167 is fixedly installed at the other end of the elastic piece 166. The circumferential surface of the rubber ring 165 contacts the bottom of the pressing plate 167. By providing the pressing plate 167, an intermittent resistance is applied to the shaped rod 152, ensuring that when the first spring 9 returns to its original state, the movable card seat 11 does not collide with the L-shaped plate 151 and preventing the screw 12 from loosening due to vibration.

[0029] During the operation of this embodiment, when the movable clamping seat 11 moves towards the fixed clamping seat 5, the compressed third spring 153 releases elastic force, pushing the I-shaped rod 152 to move synchronously towards the movable clamping seat 11, providing an auxiliary thrust for the movable clamping seat 11, effectively offsetting the compression resistance of the first spring 9 and making the operation more labor-saving; the movable clamping seat 11 moves out of contact with the roller 156, and the compressed fourth spring 155 restores and pushes the lifting frame 154 to move downward, and the movement of the lifting frame 154 drives the roller 156 to move downward; at the same time, the movement of the movable clamping seat 11 drives the support shaft 10 to move synchronously, and the circular hole on the support shaft 10 automatically separates from the long rod 158 during the movement, providing an auxiliary thrust for the movable clamping seat 11 through the I-shaped rod 152, reducing the strength required for the tester to adjust the movable clamping seat 11, and helping to ensure the accuracy of the operation. When the movable clamping seat 11 moves towards the starting position, the movable clamping seat 11 contacts the I-shaped rod 152 and pushes it to move synchronously, and the movement of the I-shaped rod 152 stretches the third spring 153; at the same time, the movable clamping seat 11 moves into contact with the circumferential surface of the roller 156 and pushes it to rise, and the movement of the roller 156 drives the lifting frame 154 to rise, and the movement of the lifting frame 154 compresses the fourth spring 155. The reaction force of the fourth spring 155 is transmitted to the roller 156 through the lifting frame 154, so that the roller 156 exerts a stable downward pressure on the movable clamping seat 11; the circular hole of the support shaft 10 moves into contact with the long rod 158, and the long rod 158 provides an additional supporting force for the movable clamping seat 11 again. By setting the roller 156 and the long rod 158, the stability of the movable clamping seat 11 at the starting position is enhanced, ensuring that the movable clamping seat 11 remains at the preset position during the toughness test process; When the I-shaped rod 152 moves towards the fixed clamping seat 5, the movement of the I-shaped rod 152 drives the sleeve plate 163 to move towards the fixed clamping seat 5. The movement of the sleeve plate 163 drives the sliding rod 162 to move towards the fixed clamping seat 5. The movement of the sliding rod 162 drives the C-shaped rod 164 to move towards the fixed clamping seat 5. The movement of the C-shaped rod 164 drives the rubber ring 165 to move towards the fixed clamping seat 5. At the same time, the sliding rod 162 moves horizontally along the fixed frame 161, and the fixed frame 161 provides support for the sliding rod 162. The sliding rod 162 transmits the support to the I-shaped rod 152 through the sleeve plate 163 to ensure the stability of the connection between the sleeve plate 163 and the I-shaped rod 152. By fixedly connecting the sleeve plate 163 to one end of the I-shaped rod 152, the stability of the I-shaped rod 152 itself is further enhanced, ensuring the smooth progress of the toughness detection. When the rubber ring 165 moves, the friction between its contact surface and the pressure plate 167 generates resistance, and the resistance is transmitted to the I-shaped rod 152 through the C-shaped rod 164, the sliding rod 162, and the sleeve plate 163, reducing its moving speed; when the rubber ring 165 separates from the pressure plate 167, the compressed elastic piece 166 releases elastic force and pushes the pressure plate 167 downward. The rubber ring 165 continues to move and contacts the pressure plate 167 again, pushing it upward. The movement of the pressure plate 167 squeezes the elastic piece 166, and the elastic piece 166 exerts a reaction force to make the pressure plate 167 and the rubber ring 165 fit tightly. At this time, the movement of the rubber ring 165 and the pressure plate 167 rub again, and the generated resistance continues to slow down the moving speed of the I-shaped rod 152. By setting the pressure plate 167, intermittent resistance is applied to the I-shaped rod 152 to ensure that when the first spring 9 resumes its original state, the movable clamping seat 11 will not collide with the L-shaped plate 151, preventing the screw 12 from loosening due to vibration.
