Problems solved by technology

At present, domestic studies have focused on the impact of tool structure, installation method, and tool coordination on the total rock-breaking energy consumption. The test bench or test equipment used in the research can basically only complete the measurement of the total energy consumption, and cannot achieve energy consumption. Dissociated measurement of consumption

Abstract

The invention discloses a testing stand for detecting the rotating rock breaking energy consumption of a cutter. The testing stand comprises a testing stand fixing frame, a first motor, a turbine decelerator, a dynamic torque sensor, an upper rotating table, a feeding mobile station and a driving mechanism of the feeding mobile station. The dynamic torque sensor in the upper rotating table and a static torque sensor in the feeding mobile station are used to measure torque loss in the cutter or a cutter combined cutting rock material, a pressure sensor array composed of four pressure sensors in the feeding mobile station is used to measure the distribution feature of force in the vertical direction, and obtained data can be used to analyze rules that structure parameters, working parameters and material composition feature of the cutter and the cutter combination influence the cutting performance and the rock bearing energy consumption characteristic. The testing stand is reasonable in structural design, reliable in working principles, simple and effective in a realization scheme, and capable of providing equipment support for researches on the rotating rock breaking energy consumption of the cutter.

Description

technical field [0001] The invention relates to a detection test bench for energy consumption of rock breaking by cutter rotation, which is suitable for mechanical detection of the process of cutting natural rock or artificial rock by a small cutter or a small combined cutter. Background technique [0002] Cutter rock breaking is an important form of rock crushing technology, and is widely used in ore mining, oil drilling, tunnel excavation, asphalt pavement crushing and other fields. When the cutter is working, in addition to the energy consumed by the crushing of rocks, concrete, and asphalt roads, a large part of the energy is consumed in the form of friction, wear, and heat. These energies not only increase the load on the crushing equipment, but also cause The rapid failure of the tool and the decline of cutting performance, therefore, should avoid or reduce the occurrence of these energy consumption methods as much as possible. The material, structure, installation me...
