Low-noise pollution-free full-automatic concrete anti-abrasion tester

Abstract

The invention relates to a low-noise pollution-free full-automatic concrete anti-abrasion tester, which comprises a closed box body. A storage bin is arranged inside the box body; a spray gun set is arranged at the bottom of the storage bin; a spray gun connecting rod mechanism is connected at the bottom of the spray gun set; a movable working platform is arranged under the spray gun connecting rod mechanism; and a material receiving box is arranged under the movable working platform; the spray gun set, the spray gun connecting rod mechanism, the movable working platform and the material receiving box are arranged in the box body; a dust removal system is connected outside the box body through a pipeline; an air compressor is arranged outside the spray gun set; and the movable working platform comprises a moving mechanism on which a test piece bearing platform is arranged, and a test piece fixing device is arranged on the test piece bearing platform. The low-noise pollution-free full-automatic concrete anti-abrasion tester has the advantages of simple structure, convenient operation, and capacity of evaluating the anti-abrasion of the concrete under the action of sand-containing current with high velocity over 60m / s and other high abrasion-resistant clad materials and developing and researching new materials, and has the characteristics of low noise, no pollution and full automation.

Description

technical field [0001] The invention relates to an experimental device, in particular to a low-noise and pollution-free full-automatic concrete anti-scour test machine. Background technique [0002] Concrete is by far the largest and most widely used building structure material. To evaluate the performance of concrete, in addition to the workability of its mixture and the mechanical properties of hardened concrete, it is necessary to consider the durability of concrete materials. Among them, the impact and wear resistance of concrete materials in structural parts such as overflow surfaces, draft pipes, flood discharge tunnels, and sand scour holes in hydraulic structures and concrete pavement materials are important technical indicators for evaluating the durability of concrete structures in these parts. [0003] In the field of water conservancy and hydropower engineering, my country promulgated the hydraulic concrete test method as early as 1962, which recommended the circ...

AI Technical Summary

Problems solved by technology

First of all, the previous impact and wear resistance test equipment cannot reach more than 40m / s, and cannot meet the test requirements of impact and wear resistance materials under the condition of sandy high-speed water flow; secondly, the traditional ring method and underwater steel ball method cannot be adjusted The grinding angle of the medium, while the traditional wind sand gun equipment can adjust the grinding angle, but it is still restricted by its grinding speed; third, the traditional wind sand gun test equipment has the problems of high noise and serious dust pollution. For the testers, the test environment and conditions are poor, and it is not easy to popularize and use
