Embodiment Construction
[0017] As shown in the figure: a hob positioning device for a hard rock roadheader cutter head, including a rotary shaft 1, a rotary sleeve 2, a positioning rail ruler 3 and a positioning block 4, and the rotary sleeve 2 is a cylinder with one end open , the rotary sleeve 2 is sleeved on the top of the rotary shaft 1 through the open end, the rotary sleeve 2 can be rotated with the rotary shaft 1 as the rotating shaft, and the closed end of the rotary sleeve 2 is provided with an adjusting bolt 9, and the stud of the adjusting bolt 9 Go through the rotary sleeve 2 and tighten the rotary shaft 1. When it is necessary to adjust the horizontal position of the rotary sleeve 2, twist the adjusting bolt 9 to make the stud part of the adjusting bolt 9 protruding into the rotary sleeve 2 longer, and then the screw of the adjusting bolt 9 The column fixes the end of the rotary shaft 1, and drives the rotary sleeve 2 to move upward, the horizontal position of the rotary sleeve 2 rises, a...

The invention relates to a hob positioning device for the cutter head of a hard rock tunneling machine, which comprises a rotary shaft, a rotary sleeve, a positioning rail ruler and a positioning block. The rotary sleeve is sleeved on the top end of the rotary shaft through an open end, and the positioning rail ruler includes Horizontal section and circular arc section, one end of the horizontal section of the positioning rail ruler is fixedly connected with the rotary sleeve, and the other end is hinged with the rotary sleeve through a pull rod. groove, and the positioning groove and the chute are arranged perpendicular to each other, the positioning block is clamped in the chute through the limit rod, and the lower end of the positioning block is provided with a U-shaped slot. The hob positioning device of the present invention can accurately position the disc-shaped hob during the production process of the hard rock tunnel boring machine cutter head, detect and deal with problems in time during the production process of the cutter head, ensure that the force on the cutter head is even, and reduce the number of cutting tools. Partial wear, uneven force, etc., save tool costs, and avoid delays in the construction site due to conditions.
Description
technical field [0001] The invention relates to the technical field of hard rock roadheader engineering machinery, in particular to a hob positioning device for a hard rock roadheader cutterhead. Background technique [0002] The full-face hard rock roadheader mainly relies on the disc-shaped hob installed on the cutter head to roll and break the rock formation on the excavation surface. The hob is a wearable part and needs to be replaced frequently. At present, the open-type hard rock roadheaders used in China are all imported equipment from abroad, and the research and development technology of hard rock roadheaders is still very weak, especially the technical requirements for hobs, which are the main components of hard rock roadheaders, are higher. If there is no reasonable and rigorous inspection during the production or maintenance process, it will lead to severe wear of the hob, or oil leakage of the tool, damage to the seal, and cracking of the knife ring due to uneve...
