Embodiment Construction

[0028] The present invention obtains the individual rotation speed of the disc-shaped hob by means of a sensor, stores the rotation speed signal and position signal of each individual in the tool group in the memory through a multi-channel signal integration device, and transmits the signal to the excavation through a wireless transmitter. machine control room. A wireless signal receiver is set in the control room of the roadheader, and the individual rotation speed signal of the disc hob represented by each signal (hereinafter referred to as "individual measured value") is stored in the computer, and compared with a pre-stored storage unit. compared to individual baseline values. The individual reference value is related to the installation position of the disc hob and the rotational speed of the disc hob.

[0029] According to the invention, an individual reference value is determined by comparing the individual measured values ​​of the disc hob with individual reference va...

Abstract

The invention discloses a system and a method for monitoring the operation state of a disc cutter group of a cutterhead of a tunneling machine. The method comprises the following steps: detecting the autorotation speed of each disc cutter by using a sensor; and transmitting a rotating speed signal to a computer in a control room of the tunneling machine by using a wireless data transmission device so as to judge the operation state of the disc cutters according to the rotating speed signal and the preset reference value relationship. The system and the method have the technical effect that the individual reference value of each individual of the disc cutter group is subjected to data processing and visual display, so that the operation state and the wear state of the disc cutter group of the tunneling machine can be displayed in real time. The monitoring system can provide selection help for an operator of the tunneling machine so as to determine whether to replace and maintain cutters or not, or change a tunneling control parameter to reach higher cutter group operation performance. By the method, manpower consumption can be reduced obviously, construction risk can be reduced, and work efficiency can be improved.

Description

technical field [0001] The invention relates to a monitoring system and method for a full-face tunneling machine, in particular to a system and method for monitoring the operating state of a group of disc-shaped hobs. Background technique [0002] In the excavation of long tunnels in major projects such as railways, highways, and water transfers, the rock-breaking tools used by roadheaders, especially disc hobs, are in a continuous wear process. There are multiple same or different knives installed on the cutter head of the roadheader, and the wear state of each knives is related to its installation position and the rock breaking process (replacement of new knives or tool parts in the middle of excavation). If a single member of the cutter group is severely worn, it will affect the overall performance of the cutter group (the overall rock-breaking ability of the cutter group is weakened), and it is advantageous to replace the single cutter at this time. The realization of t...
