Description

A trapezoidal tear test fixture for geotextile Technical Field

[0001] This utility model relates to the field of material testing fixture technology, and in particular to a geotextile trapezoidal tear test fixture. Background Technology

[0002] Geotextile, also known as geotextile fabric, is a permeable geosynthetic material made of synthetic fibers through needle punching and weaving processes. It is widely used in water conservancy, transportation and environmental protection engineering. The geotextile trapezoidal tear test fixture is a special device used to test the trapezoidal tear performance of geotextile. It is made of high-strength metal material and has a certain rigidity and stability to ensure that it can withstand large tensile forces without deformation during the test.

[0003] A search revealed Chinese Patent Publication No. CN219348434U, which discloses a clamp for a nail bar tear test of pre-laid waterproof membrane, comprising: a lower U-shaped clamp; a clamping cylinder fixed to the outer wall of the lower U-shaped clamp, with a piston rod extending through the lower U-shaped clamp into its interior; a clamping plate disposed on the piston rod of the clamping cylinder and located inside the lower U-shaped clamp, for engaging with the inner wall of the lower U-shaped clamp to clamp the lower part of the pre-laid waterproof membrane; a nail bar disposed at the end of the clamping plate away from the clamping cylinder; and an upper clamp located above the lower U-shaped clamp for clamping the upper part of the pre-laid waterproof membrane. The pre-laid waterproof membrane is stretched and then fixed to the inner wall of the lower U-shaped clamp by using a clamping cylinder to move the clamping plate. This improves the stability of the pre-laid waterproof membrane during the nail tear test, resulting in more accurate experimental data. However, the waterproof membrane will produce tear fragments during the tear test, which will enter the clamp of the testing equipment, causing loose clamping and uneven force, thus affecting the clamping effect of the clamp on the sample and consequently affecting the test results. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a geotextile trapezoidal tear test fixture, which aims to improve the problem in the prior art where tear debris enters the fixture of the testing equipment, resulting in loose clamping and uneven force, thus affecting the clamping effect of the fixture on the sample.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a geotextile trapezoidal tear test fixture, comprising a body, with multiple testing fixtures equidistantly installed on the top of the body; elongated short plates fixedly connected to the left and right sides of the top of the body; a bidirectional threaded rod rotatably connected to an adjacent side of the outer wall of the elongated short plate; a worm gear fixedly connected to the middle of the outer wall of the bidirectional threaded rod; a second motor fixedly connected to the top of the body; a worm fixedly connected to the output end of the second motor; the worm meshing with the worm gear; multiple moving blocks equidistantly threadedly connected to the outer wall of the bidirectional threaded rod; an inner slider guide plate fixedly connected to the top of the body; multiple vacuum cleaners equidistantly fixedly connected to the rear side of the outer wall of the body; a connecting pipe connected to the top of each vacuum cleaner; a suction head fixedly connected to the front side of the outer wall of each moving block; the rear end of the outer wall of each suction head communicating with the front end of the outer wall of the connecting pipe; and multiple heat dissipation mechanisms equidistantly installed on the inner wall of the body for heat dissipation of the interior of the body.

[0006] The above technical solution works as follows: By turning on motor two, the output end of motor two drives the worm to rotate. Since the worm is meshed with the worm wheel, the rotation of the worm wheel will drive the bidirectional threaded rod to rotate synchronously. The moving block on the outer wall of the bidirectional threaded rod will move to both sides and the middle under the guidance of the inner slider guide plate, thereby adjusting the dust collection head to a suitable position. Then, the vacuum cleaner is turned on. The vacuum cleaner is connected to the dust collection head through the connecting pipe and generates suction. Since the dust collection head is adjusted to a suitable position, it can promptly suck away the debris generated by tearing, preventing the debris from entering the fixture of the testing equipment.

[0007] As a further description of the above technical solution:

[0008] The heat dissipation mechanism includes an elongated inner sliding plate, which is equidistantly installed inside the body. A rack is slidably connected inside the elongated inner sliding plate. A motor is fixedly connected to the rear side of the outer wall of the body. A gear is fixedly connected to the output end of the motor and meshes with the rack. A T-shaped plate is fixedly connected to the front side of the outer wall of the rack. A battery plate is fixedly connected to one end of the outer wall of the T-shaped plate away from each other. A fan is fixedly connected to the front side of the outer wall of the T-shaped plate.

[0009] The above technical solution works as follows: by turning on the motor, the gear at the output end rotates. Since the gear meshes with the rack, the rotation of the gear will drive the rack to slide inside the long inner slide plate. The sliding of the rack will cause the T-shaped plate and the front fan to move. Then, after the fan is powered on, it will start to work, generate airflow, blow air to cool the inside of the machine, and expel the heat from the machine.

[0010] As a further description of the above technical solution:

[0011] A ventilation filter is installed on the right side of the outer wall of the machine body.

[0012] Through the above technical solution, the ventilation filter can promote air circulation and heat dissipation inside the machine.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the machine body is threaded with a screw, and the outer wall of the screw is threaded with a warning sign.

[0015] The aforementioned technical solution—warning signs—can remind staff of precautions when operating equipment, thereby reducing the probability of accidents.

[0016] As a further description of the above technical solution:

[0017] A hollow box is fixedly connected to the top front side of the machine body, and a drawer is slidably connected inside the hollow box.

[0018] The above technical solution allows for the convenient storage of tools used daily and for maintenance through sliding drawers inside the hollow box.

[0019] As a further description of the above technical solution:

[0020] A handle is fixedly connected to the front side of the outer wall of the drawer, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0021] The above technical solution provides a handle fixedly connected to the front of the drawer's outer wall, which facilitates the opening and closing of the drawer and the use of the items stored inside.

[0022] As a further description of the above technical solution:

[0023] Each of the four corners at the bottom of the body is fixedly connected to a fixing block, and a caster wheel is fixedly connected to the bottom of the outer wall of the fixing block.

[0024] The above technical solution allows the omnidirectional wheels at the bottom of the machine to facilitate the movement of the machine to different locations for use.

[0025] As a further description of the above technical solution:

[0026] A long hollow plate is fixedly connected to the right side of the outer wall of the machine body, and multiple hooks are equidistantly slidably connected inside the long hollow plate.

[0027] The above technical solution allows for the convenient hanging of tools for daily use and cleaning of the machine body via hooks on the right side of the outer wall.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the worm gear at the output end is driven to rotate by starting the second motor. The worm gear meshes with the worm wheel, so that when the worm wheel rotates, it synchronously drives the bidirectional threaded rod to rotate. The moving block on the threaded rod moves to both sides and the middle, and the dust suction head is adjusted to an appropriate position. Then, the vacuum cleaner is turned on to generate suction force, which promptly sucks away the debris generated by tearing, preventing it from entering the test equipment fixture. This avoids the problem that tearing debris will enter the test equipment fixture, causing loose clamping and uneven force, thus affecting the clamping effect of the fixture on the sample.

[0030] 2. In this utility model, after the motor is started, it drives the gear to rotate and drives the rack to slide in the slide plate, thereby pushing the T-shaped plate and the fan to move. The powered fan generates airflow to cool the machine body and dissipate heat, thereby reducing the internal temperature of the machine body and ensuring the normal operation of the equipment.

[0042] Specifically, by turning on the motor 206, the output gear 207 is rotated. Since the gear 207 is meshed with the rack 202, the rotation of the gear 207 will drive the rack 202 to slide inside the elongated inner slide plate 201. The sliding of the rack 202 will drive the T-shaped plate 203 and the front fan 205 to move.

[0044] Specifically, a fixing block 11 is fixedly connected to each of the four corners at the bottom of the body 1. A caster wheel 10 is fixedly connected to the bottom of the outer wall of the fixing block 11. The caster wheel 10 at the bottom of the body 1 makes it easy for staff to move the body 1 to different places for use. A long hollow plate 13 is fixedly connected to the right side of the outer wall of the body 1. Multiple hooks 12 are equidistantly slidably connected inside the long hollow plate 13.

[0045] Working principle: The geotextile to be tested is cut into a suitable shape and fixed using the testing clamp 5. The testing clamp 5 consists of upper and lower parts connected by bolts, and has barbs on opposite sides to effectively clamp the geotextile and prevent it from slipping during testing. Then, the motor 19 is turned on, and the output end of the motor 19 drives the worm 21 to rotate. Since the worm 21 is meshed with the worm wheel 20, the rotation of the worm wheel 20 will drive the bidirectional threaded rod 16 to rotate synchronously. The moving block 22 on the outer wall of the bidirectional threaded rod 16 will slide against the inner slider. Guided by the guide plate 24, the vacuum head 23 moves to the sides and center, thereby adjusting it to a suitable position. Then, the vacuum cleaner 17 is turned on. The vacuum cleaner 17 is connected to the vacuum head 23 through the connecting pipe 18, generating suction. Since the vacuum head 23 is adjusted to a suitable position, it can promptly remove the debris generated by tearing, preventing the debris from entering the clamp of the testing equipment. This avoids the problem of loose clamping and uneven force caused by tearing debris entering the clamp of the testing equipment, which would affect the clamping effect of the clamp on the sample.

[0046] By turning on the motor 206, the output gear 207 is rotated. Since the gear 207 is meshed with the rack 202, the rotation of the gear 207 will drive the rack 202 to slide inside the elongated inner slide plate 201. The sliding of the rack 202 will cause the T-shaped plate 203 and the front fan 205 to move. Then, after the fan 205 is powered on, it will start to work, generate airflow, blow air to cool the inside of the machine body 1, and expel the heat from the outside of the machine body 1, thereby reducing the internal temperature of the machine body 1 and ensuring the normal operation of the equipment.
