Problems solved by technology

At present, there are basically no test benches at home and abroad that can perform rapid rock-breaking simulation of rock tunneling machines. The single hob test bench can only conduct quantitative analysis from the depth and width of cracks produced by rolling rocks. The influence of rock breaking efficiency and tool wear cannot be truly measured

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] In the experimental process of the present invention, the movement of the workpiece is used to drive the hob to rotate around its own axis. The hydraulic system pulls the workpiece to reach the set speed, and the penetration adjustment of the hob depends on the tool hydraulic system. The adjustment of the distance between the workpiece and the tool is through the respective adjustment mechanism, and the tool is positioned mechanically after adjustment, which is simple and reliable.

[0020] The gist of the present invention lies in its structure and principle. Its working principle is that under the action of the cutter hydraulic system, the base of the cutter head drives the hob to move up and down as a whole, and produces a certain degree of penetration into the rock surface. The parts produce movement and displacement, and the movement of the worktable driv...

Abstract

The invention relates to a double hobbing cutter rock hobbing comprehensive test bed, which relates to rock tunnel boring machine hobbing cutter experimental equipment. The double hobbing cutter rock hobbing comprehensive test bed comprises a hydraulic system, a worktable, cutters, cutter holders, guide rails, a test system, a control system and the like. The worktable is pulled by a hydraulic system to move quickly and a test piece drives the hobbing cutters to hob rocks, the position of the test bed in the direction vertical to the motion direction of the worktable is adjusted by a screw, and the pressure plates at two ends of the worktable lock the test piece. The cutter holders are connected with cutter hydraulic push / pull rods through connecting discs; seven steel-embedding sliding blocks on four sides are matched with the steel-embedding guide rails on a test bed body to absorb the impact exerted by lateral loads on the hydraulic push rods; the hydraulic system drives the entire cutter holders to enter penetration regulation and keep a hobbing pressure. The test bed is reasonable, simple and safe in structural design and high in bearing capacity and impact strength.

Description

technical field [0001] The present invention relates to a rock excavator hob test equipment, in particular to an experimental device for fast and multi-size hobs to simulate rock breaking——double hob rolling rock comprehensive test bench, which is the design and research of rock excavator important equipment for experiments. It belongs to the design and manufacture technology of large-scale test bench. Background technique [0002] The rock boring machine is a large-scale tunneling equipment that realizes the industrialization of rock breaking, slag removal, transportation, lining, support, etc. It is safe, fast, efficient, has little environmental damage, and is not affected by the climate. It is now widely used It is suitable for tunnel projects that need to pass through rock formations such as railways, hydropower, highways, subways and municipalities. In the design and research of rock boring machine tools, it is the basis to determine the rock breaking mechanism, effi...
