Abstract
The utility model relates to a holding device for geotextile tensile property detection. The utility model aims to solve the technical problem that the holding device provided by the utility model can prevent the geotextile to be detected from sliding and rupturing in detection and has the characteristics of simple structure and high operation convenience. The technical scheme is as follows: the holding device for geotextile tensile property detection comprises a mobile holder capable of moving up and down along a guide rail, and a fixed holder which is positioned below the mobile holder and used for fixing the geotextile sample, wherein the holding surfaces of the mobile clamper and the fixed holder are sawtoothed. The utility model is characterized in that the sawtoothed surfaces of the mobile holder and the fixed holder are respectively covered with a backing fabric. The sawtooth tips of the holding surface of the mobile holder are arranged upwards, and the sawtooth tips of the holding surface of the fixed holder are arranged downwards.
Description
Technical field
The utility model relates to the textile industry field, especially a kind of clamping device that is used for the detection of geotextile tensile property.
Background technology
Geotextile is claimed geotextile again, and it is the water permeability geosynthetics that is formed through acupuncture or braiding by synthon; Finished product is the cloth shape, and general width is a 4-6 rice, and length is 50-100 rice.Geotextile is divided into spins geotextile and non-woven geotextile.Geotextile has outstanding filtration, draining, isolation, reinforcement, antiseepage, protective action; And also have in light weight, tensile strength is high, good penetrability, high temperature resistant, anti-freezing, ageing-resistant, corrosion resistant characteristics, therefore is used for aspects such as highway, railway, water conservancy, heavy construction, power plant's ash dam construction, non-ferro metals debris processing, environment-friendly engineering, water and soil conservation in a large number.
The length growth rate of the tension test of geotextile and the data of pulling strengrth are to judge one of important indicator that whether qualified geotextile is.Because purposes is different; Enterprise towards the difference of user's industry, the detection means and the method for every profession and trade are not quite similar, the difference of measuring at present with these two indexs of a kind of GSZ product is about 20%; Make manufacturing enterprise at a loss as to what to do, had a strong impact on the quality cost control of product.Trace it to its cause the GSZ of GSZ, particularly spun glass; Its fragility and hardness are arranged; Big, the wide characteristic of braid and unit with present traditional textile fabric tension research technique and method, can't be avoided slippage and clamp port fracture in test process.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology; A kind of clamping device that the geotextile tensile property detects that is used for is provided; This clamping device should be able to prevent geotextile to be detected slip and fracture when detecting, and also has simple in structure and characteristics simple operation.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of clamping device that is used for the detection of geotextile tensile property; The fixed clamp device that is used for fixing the geotextile sample that comprises the mobile clamper that moves up and down along guide rail and be positioned at said mobile clamper below; The clamping face of said mobile clamper and fixed clamp device is a zigzag, it is characterized in that: the serrated surface of said mobile clamper and fixed clamp device is coated with one deck liner cloth.
Arrange up at the sawtooth tip of the clamping face of said mobile clamper, and arrange down at the sawtooth tip of the clamping face of said fixed clamp device.
The beneficial effect of the utility model is: because the sawtooth tip end surface of the clamping face of the described clamper of the utility model is coated with one deck liner cloth; Therefore can prevent effectively that the geotextile sample is torn because of mobile clamper moves up and down in testing process; And the sawtooth tip of the clamping face of mobile clamper and fixed clamp device is towards difference, thereby guaranteed that the geotextile sample can not move up and down in testing process.
Description of drawings
Fig. 1 is the structural representation of geotextile tensile property pick-up unit.
Fig. 2 is the A portion structure for amplifying synoptic diagram among Fig. 1.
Embodiment
Below in conjunction with Figure of description, the utility model is described further.
As shown in Figure 1, the principle of work of geotextile tensile property pick-up unit (this device is the conventional sense device of outsourcing) is: motor 5 rotates through shaft coupling 6 and drives 7 rotations of T type screw rod, and the mobile clamper that is fixed on the T type nut 8 moves up; The geotextile sample that carries out tension test is through moving and fixing a pair of clamper realizes that constant speed stretches, and writes down it when breaking to break force of the breath, and this power is the ultimate strength of sample.
But owing to move the clamping face of clamper and fixed clamp device is zigzag, when constant speed stretching geotextile sample, can tear geotextile, thereby influence test result.
The utility model carries out following improvement to above shortcoming to the clamping device in the geotextile tensile property pick-up unit:
As shown in Figure 2; A kind of clamping device that is used for the detection of geotextile tensile property; The fixed clamp device 2 that is used for fixing geotextile sample 4 (move clamper and be the conventional clamp structure that adopts bolt 9 to fix) that comprises the mobile clamper 1 that moves up and down along guide rail and be positioned at said mobile clamper below with the fixed clamp device; The clamping face of said mobile clamper and fixed clamp device is a zigzag; In order to prevent that the geotextile sample from being torn when stretching, therefore the serrated surface at said mobile clamper and fixed clamp device covers one deck liner cloth 3.This layer liner cloth can be bonded and fixed at serrated surface; Be individual components perhaps, be coated on the geotextile surface during use again, geotextile is carried out clamping by mobile clamper and fixed clamp device.Said liner cloth can be the geotextile of same quality, or the woven sheet of other kind.
In order to prevent that the geotextile sample from moving up and down because stretch when testing; Therefore arrange up at the sawtooth tip of the clamping face of said mobile clamper; Arrange down at the sawtooth tip of the clamping face of said fixed clamp device, such structure can be effectively fixing geotextile sample.
Claims (2)
1. one kind is used for the clamping device that the geotextile tensile property detects; The fixed clamp device (2) that is used for fixing geotextile sample (4) that comprises the mobile clamper (1) that moves up and down along upright guide rail and be positioned at said mobile clamper below; The clamping face of said mobile clamper and fixed clamp device is a zigzag, it is characterized in that: the serrated surface of said mobile clamper and fixed clamp device is coated with one deck liner cloth (3).
2. a kind of clamping device that the geotextile tensile property detects that is used for according to claim 1, it is characterized in that: arrange up at the sawtooth tip of the clamping face of said mobile clamper, and arrange down at the sawtooth tip of the clamping face of said fixed clamp device.
