Problems solved by technology

At present, the test devices for studying the dynamic characteristics of rocks are mainly Hopkins compression rods and drop weight impact devices, but these devices are loaded at both ends (or two points) at the same time, and cannot achieve single-point impact tests on rock blocks.
At present, there are few researches on the accelerated collision device of rock samples at home and abroad, and the technology is not mature, especially the speed control accuracy of rock samples is poor, and the speed range that can be realized is small

Abstract

The invention provides a rock collision test device, which comprises a rack, a rodless cylinder, a gas storage tank, a vacuum holding assembly, an upper intake and exhaust assembly, a lower intake andexhaust assembly, an air compressor, a collision assembly, a first photoelectric sensor, a high-speed camera, a controller, and also includes a rebound protection assembly. The rock collision test device provided by the invention utilizes the rodless cylinder, the upper intake and exhaust assembly and the lower intake and exhaust assembly to realize adjustment of rock collision velocity, and canacquire a high collision velocity, utilizes the rebound protection assembly to strictly control the number of times of collision, utilizes the collision assembly to realize adjustment of the collisionangle, utilizes the vacuum holding assembly to hold spheres and cylinder impact blocks of various sizes, and utilizes an electrical control structure to achieve high precision control, and has the characteristics of simple operation and strong practicability.

Description

technical field [0001] The invention belongs to the field of rock impact tests, in particular to a rock impact test device. Background technique [0002] Rock impact test is one of the basic methods to study rock dynamic behavior. At present, the test devices for studying the dynamic characteristics of rocks are mainly Hopkins compression rods and drop weight impact devices, but these devices are loaded at both ends (or two points) at the same time, and cannot realize single-point impact tests on rock blocks. At present, there are few researches on the acceleration and collision device of rock samples at home and abroad, and the technology is not mature, especially the speed control accuracy of rock samples is poor, and the speed range that can be realized is small. Contents of the invention [0003] In view of the above technical problems, the present invention provides a rock impact test device with adjustable impact speed. [0004] In order to solve the problems of th...
