Problems solved by technology

Hob replacement is a major factor restricting the efficiency of tunnel excavation. At present, it is mainly replaced manually. Faced with the extremely harsh high-pressure and high-humidity working environment, it is difficult to guarantee the safety of the tool changer and the efficiency of tool change is extremely low.
The traditional hob installation requires many parts (about 15), and the assembly and disassembly actions are very complicated

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions.

[0024] When the full-face tunnel boring machine is shut down, the manipulator is used to replace the integrated tool holder system. The assembly and disassembly of the whole mechanism is as follows:

[0025] Step 1: The manipulator sends the entire integrated knife block system into the hob tool box 1 by grabbing the hob grab bar 2-8, and at this time, the four side sliders 2-7 are in a retracted state. The state diagram and section view of the integrated knife block system when it is not installed in the knife box are as follows: Figure 5 , 6 shown.

[0026] Step 2: The manipulator rotates and tightens the bolt rod 2-3, drives the middle slider 2-6 to move downward through thread transmission, and at the same time, the middle slider 2-6 drives the four side sliders 2-7 to move in translation, thus exte...

Abstract

The invention belongs to the technical field of tunnel boring construction equipment. A hobbing cutter head for a full face rock tunnel boring machine based on robot cutter exchange is designed according to structural space of a cutter head of the tunnel boring machine. The hobbing cutter head mainly comprises three parts: a cutter box, an integrated cutter block system and a hobbing cutter. According to the integrated cutter block system, the cutter exchange flow can be simplified, the cutter exchange time is shortened, the complicity of the cutter exchange manipulator design is reduced and manual cutter exchange operation is better changed. Therefore, life safety of cutter exchange workers is better ensured, the cutter exchange efficiency is improved, boring period is shortened, and theconstruction cost of the whole tunnel engineering is reduced.

Description

technical field [0001] The invention belongs to the technical field of tunnel excavation construction equipment. According to the structural space of the tunnel boring machine cutterhead cutter holder, a full-section rock tunnel boring machine hob cutter holder based on robot tool change is designed. Background technique [0002] Various areas along the line have been developed on a large scale, and many large-scale infrastructure projects such as roads, railways, water conservancy and hydropower projects, urban subways, and urban sewage drainage have been rapidly planned and constructed. The huge market places higher requirements on the construction safety and efficiency of full-face tunnel boring machines. Hob replacement is a major factor restricting the efficiency of tunnel excavation. At present, it is mainly replaced manually. Faced with the extremely harsh high-pressure and high-humidity working environment, it is difficult to guarantee the safety of the tool change w...
