Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a geotextile tear resistance detection device. Background Art

[0002] Geotextile, also known as geotextile, is a permeable geosynthetics made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetics. The finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextile is divided into woven geotextile and non-woven filament geotextile. It has high strength. Due to the use of plastic fibers, it can maintain sufficient strength and elongation in dry and wet states. It is corrosion-resistant and can resist corrosion for a long time in soil and water with different pH values. It has good permeability and there are gaps between the fibers, so it has good water permeability. It has good anti-microbial properties and is not damaged by microorganisms or insect infestations. After the production and processing of the geotextile, in order to ensure whether the tear resistance of the geotextile is qualified, the produced geotextile needs to be tested for tear resistance.

[0003] At present, when the geotextile is tested for tear resistance, due to its high flexibility, the geotextile is prone to fall off during the test, which results in the geotextile failing to achieve tear detection results and reduces the geotextile tear detection effect. Therefore, in view of the above technical problems, a geotextile tear resistance detection device is proposed. Utility Model Content

[0028] See also Figures 1 to 3 In one embodiment, the clamping mechanism includes a winding rod 8, two groups of clamping plates 7, a first driving member, a tearing block 11, multiple groups of clamping blocks 14 and a second driving member. One end of the winding rod 8 is fixedly arranged on the inner wall of the detection box 2. The two groups of clamping plates 7 are symmetrically arranged relative to the axis of the winding rod 8 and are connected to the detection box 2 through the first driving member.

At the same time, the symmetrical arrangement of the two groups of clamping plates 7 can balance the force of the winding rod 8 when clamping the geotextile wrapped around the winding rod 8, and prevent the winding rod 8 from bending.

[0031] On the basis of the above embodiment, further, the clamping plate 7 is in a semicircular arc shape, which can increase the contact area between the clamping plate 7 and the geotextile wound on the winding rod 8, and improve the firmness of clamping and fixing the geotextile.

[0038] The specific implementation of the above-mentioned geotextile tear resistance detection device is as follows:

[0039] When testing the tearing of the geotextile, firstly, the box door 3 is opened by holding the handle 4, and then the geotextile is placed in the test box 2 through the opening, and one end of the geotextile is wound on the winding rod 8, and then the multiple groups of electric push rods 6 are controlled to extend, and the extension of the multiple groups of electric push rods 6 can drive the two groups of clamping plates 7 to move closer, and the two groups of clamping plates 7 move closer to clamp and fix the geotextile wound on the winding rod 8, and then the other end of the geotextile is placed in the clamping groove, and is located between the multiple groups of pressing blocks 14 and the multiple groups of positioning grooves 15, and then the multiple groups of screws are rotated respectively. The threaded rod 13 and multiple groups of threaded rods 13 can be rotated and matched with the threads of the tearing block 11 to drive the multiple groups of threaded rods 13 to move. The movement of multiple groups of threaded rods 13 can drive the multiple groups of clamping blocks 14 to move. The movement of multiple groups of clamping blocks 14 and the matching of multiple groups of positioning grooves 15 can clamp and fix the geotextile on the tearing block 11. The two ends of the geotextile are clamped and fixed by the matching of the winding rod 8 and the two groups of clamping plates 7 and the matching of multiple groups of clamping blocks 14 and the multiple groups of positioning grooves 15, so as to prevent the geotextile from falling off during the detection process and improve the geotextile tear detection effect.

[0040] After the two ends of the geotextile are clamped and fixed, the box door 3 is closed, and then the electric hydraulic push rod 10 is controlled to retract. The retraction of the electric hydraulic push rod 10 can drive the tearing block 11 to move away from the winding rod 8 through the tension sensor 12 to perform geotextile tear resistance detection. During the detection process, the tension sensor 12 can transmit the data information detected by the pulling to the display screen 16 and display it through the display screen 16. At this time, the tear resistance of the geotextile can be judged by observing whether the geotextile in the detection box 2 is torn and the tension applied to the geotextile displayed on the display screen 16 through the perspective window 17.

[0041] It can be understood that the electric push rod 6, the electric hydraulic push rod 10, the tension sensor 12 and the display screen 16 are all powered by an external power supply and are all existing technologies, and their working principles are not repeated here.
