Embodiment Construction

[0029] In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with specific implementation methods:

[0030] Such as Figure 1-7 As shown, the present invention proposes a roadheader positioning device and a positioning method thereof, comprising the following steps:

[0031] S1: Generate the tunnel model 8 according to the tunnel design and generate the cutting range model 7 according to the activity range of the cutting head 1 .

[0032] S2: Determine the positioning origin, establish a coordinate system, generate the coordinates of the tunnel model 8 and the coordinates of the cutting range model 7,

[0033] S3: Preliminary positioning of the roadheader, determine the coordinates of the cutting model of the roadheader.

[0034] S4: Select a base point 6, and determine a reference plane 3, which is a cross-section o...

Abstract

The invention discloses a tunneling machine positioning-tunneling method and system, and belongs to the field of building method and equipment. A positioning punching device for a hard rock layer based on the tunneling machine positioning-tunneling method and the new system is included. The tunneling machine positioning-tunneling method comprises the following steps that S1, a tunnel model is generated according to tunnel design, and a model is generated according to the moving range of a cutting head; S2, a positioning original point is determined, a coordinate system is established, and tunnel model coordinates and cutting range model coordinates are generated; S3, a tunneling machine is positioned preliminarily, and cutting model coordinates of the tunneling machine are determined; S4,a base point is selected, and a datum plane is determined; S5, coordinates of a to-be-cut body are determined according to the datum plane and the cutting depth of each time; and S6, tunneling operation is started. By adopting small-section type cutting and matching automatic positioning control, the problem that under the situation that a cutting machine is manually controlled, the tunnel position error and the accumulative error are prone to being generated is solved.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation, in particular to a positioning boring device for a boring machine and a positioning excavation method. Background technique [0002] A roadheader is a machine used to excavate tunnels on flat floors; rock is broken mechanically. Commonly used in tunnels and coal mining. According to the structural composition, it can be divided into cantilever boring machine and shield machine. Among them, the shield machine is suitable for long and straight tunnel excavation, such as subways and ultra-long mountain tunnels. , walking mechanism, frame and turntable, hydraulic system, electrical system, cooling and dust removal water supply system and operating system; the cantilever roadheader has greater flexibility and can be used for any type of support; compared with the shield machine ; It has the advantages of less investment, short construction preparation time and high reuse type. In some sh...
