Abstract

The invention discloses wear testing equipment in the field of geotextile wear testing, comprising a base, a support column fixedly connected to the upper end of the base, a guide rail fixedly connected to the upper end of the support column, a guide column fixedly connected to the upper end of the guide rail, an upper bottom plate slidably arranged on the circumferential surface of the guide column, and a guide cylinder and a spring fixedly connected to the upper end of the upper bottom plate, a telescopic rod is slidably arranged in the guide cylinder, a moving plate is fixedly connected to the upper end of the telescopic rod, a third sliding groove is formed in the upper end face of the moving plate, a double-thread lead screw is rotatably connected into the third sliding groove, a second handle is fixedly connected to the side end of the double-thread lead screw, and a first thread block and a second thread block are in threaded connection with the circumferential face of the double-thread lead screw; and the lower end of the first thread block is rotationally connected with a supporting rod, the lower end of the supporting rod is rotationally connected with the second connecting block, and the lower end of the second connecting block is fixedly connected with a pressing plate. The structure is simple, the manufacturing cost is low, and the upper bottom plate can be conveniently pressurized only through simple operation.

Description

technical field [0001] The invention relates to the field of geotextile abrasion testing, in particular to an abrasion testing equipment. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is cloth-like, with a general width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles. [0003] However, in the traditional wear test of geotextiles, a certain amount of pressure is required to test the wear resistance of the geotextiles, and the traditional way of increasing pressure is to increase the pressure by adding weights, so that when testing It is necessary to prepare a variety of weights for pressurization, so that when testing, testers are required to find relevant weights to increase, which increases the difficult...
