Abstract

The invention discloses a comprehensive rock impacting breaking test stand which comprises a rotating speed sensor, a propelling part, a rock drill, a displacement sensor, a travel switch, a rear support, a lifting table, a thrust rack, a rotating rack and a pendulum bob part. Optional height adjustment in the operating range, horizontal movement of rock and change of the included angle between a tool and the rock can be realized, holes in large rock at different regular positions are formed, the empty hole effect of the rock is researched, the research of rock breaking by combining impacting and rock breaking methods in other forms is realized by virtue of rapid replacement equipment, and the research of rock impacting breaking under single impact and continuous impact conditions is realized. The comprehensive rock impacting breaking test stand disclosed by the invention can serve as both research equipment in a lab and performance detection equipment in factories of rock drills, hydraulic hammers, down-the-hole drills and the like.

Description

technical field [0001] The invention relates to a test bench, in particular to a comprehensive rock crushing test bench suitable for testing the rock crushing process and the performance of impact equipment. Background technique [0002] Impact is an extremely simple means of breaking rocks, which can obtain great crushing capacity in an instant, and is an important method of breaking rocks. For a long time, people have studied the properties of impact-broken rocks mainly from the aspects of single impact and repeated impact, which usually require a variety of test benches. And at the present stage, the combination of impact and other forms of rock-breaking methods is a trend. For this purpose, various forms of test benches are designed, especially to study the impact of void effect on rock breaking, which requires a large volume of rock, and also The location of the punching hole is very demanding, and there is a lack of such test equipment.
