Embodiment 1

[0038] see Figure 1 ~ Figure 4 , TBM bolter system, including the main beam 1 of the roadheader, the arc ring gear 2, the push beam 3 connected to the arc ring gear, the swing cylinder 4 for adjusting the angle of the push beam, and the crawling trolley 5 for adjusting the position of the push beam , propulsion beam oil cylinder 6, rock drill 7 and bolt 8 installed on the propulsion beam; bolter system such as figure 1 shown.

[0039] On the bolter system, assemble the forward and backward travel travel sensor, crawler trolley encoder, swing cylinder encoder, propulsion beam oil cylinder pressure sensor, rock drill propulsion pressure sensor, and rock drill propulsion flow sensor.

[0040] Set the positional relationship between the bolt hole and the tunnel axis, the number of bolts, the depth of the bolt and other parameters on the main controller, click start, and the TBM bolter system starts to drill the bolt automatically.

[0041] A method for controlling automatic bol...

Abstract

The invention provides an automatic bolt application control method for a hard rock tunneling machine. The method includes the following steps: locating the bolter system to determine the current bolt position; the main control controls the bolter system to automatically move to reach the preset bolt hole position; when the measured current bolt hole position and the preset bolt hole When the positions are consistent, the bolter system starts to perform automatic bolting operation. After the bolter system is controlled to push the beam against the hole wall, then control the bolter bit to contact the hole wall, and adopt the mode of drilling first and then drilling; repeat the operation , when all preset anchor holes are drilled and bolted, the automatic bolting control of the roadheader is completed. The invention realizes the automatic control of the bolter system of the hard rock roadheader, reduces the uncertainty caused by manual operation, and improves the automation level; through the step-by-step control of the bolting process, the bolter is protected from accidents. Damaged, improving the service life of the rock bolter.

Description

technical field [0001] The invention relates to the technical field of full-section hard rock tunnel boring machines, in particular to an automatic bolting control method for hard rock tunnel boring machines. Background technique [0002] Full-face hard rock tunnel boring machine (TBM) is a factory-like assembly line tunnel construction equipment integrating mechanical, electrical, hydraulic, optical, and gas systems, including open TBM, single-shield TBM and double-shield TBM, which can be used for The continuous operation of excavation, support, slag discharge and other construction processes has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It is widely used in China's railway, hydropower, transportation, mining, municipal and other tunnel projects. [0003] As a key component on the TBM, the bolter system plays a supporting role in the tunneling. At present, the research on the bolter system mainly focuses on the imp...
