Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 4 Shown:

[0017] The electronic control system 1 is connected to the hydraulic station 2, and the hydraulic station 2 is connected to the hydraulic rotary motor 12 through a hydraulic hose. The hydraulic station 2 provides power for the hydraulic rotary motor 12. During the test, the electronic control system 1 controls the speed of the hydraulic rotary motor 12. Its maximum speed is 8rad / s, and its maximum torque is 80000Nm;

[0018] Two sets of threaded holes and through holes are respectively opened on the four walls of the sample box 4, and the adjusting bolt 7 is installed on the sample box 4 through these threaded holes and through holes, and the adjusting bolt 7 is on one side of the sample box 4 There is a sample baffle 6 connected to the end of the sample baffle 6, and the sample 5 is placed close to the sample b...

Abstract

The invention relates to a mechanical rock breaking test machine rotation rock breaking apparatus, and belongs to the technical filed of geotechnical test machines. The apparatus comprises a control system, a hydraulic station and a mechanical portion. The mechanical portion is a main body, and is composed of a steel sample case, a torque transmission mechanism and a vertical force transmission mechanism. A hydraulic system is used for applying a pressure to a sample and comprises a hydraulic motor and the hydraulic station, and the control system is used for controlling the hydraulic system to apply an adjustable torque and an adjustable rotation speed to the sample. Samples having different dimensions and properties can be replaced in tests.

Description

technical field [0001] The invention is a rotary rock-breaking device of a mechanical rock-breaking testing machine, which belongs to a component of a mechanical rock-breaking testing machine. When used together with a mechanical rock-breaking testing machine, the device can make a sample rotate at a predetermined speed under the action of a cutter to simulate a tunnel The rock breaking process of the hob of the roadheader or the cutting tool of the raise boring machine can be applied to the rock breaking mechanism of the tunnel boring machine or the raise boring machine, the optimal design of the cutter head, the optimized construction and the construction prediction, etc., and belongs to the technical field of geotechnical testing machinery. Background technique [0002] Since the 1970s and 1980s, the full-face rock boring machine has achieved unprecedented development. Because of its fast construction speed, friendly working environment, economical and safe construction, e...
