More particularly, the present invention relates to an apparatus for measuring the abrasion rate of a disc cutter for measuring a wear rate of a disc cutter mounted on a TBM (Cutter Boring Machine) cutter head for excavating a section of a rock, And a method of measuring wear rate of a disk cutter.

Excavation by TBM is advantageous for constructing a long tunnel compared to blasting excavation.

Recently, excavation of tunnels and underground spaces have been carried out in order to increase the stability of workers, reduce civil complaints caused by noise and vibration, reduce air and air pollution, and replace TBM And the mechanization work by the engine is greatly increased.

Tunnel Boring Machine (hereinafter abbreviated as "TBM") used for tunneling mechanized tunneling is different from the conventional blasting method in that it has few environmental damage factors such as noise and vibration, It is known that it is advantageous in securing the stability of the tunnel by preventing the relaxation, and it is possible to induce the high speed excavation under the homogeneous ground condition, and it is known that the construction period and the construction cost can be saved more than the blasting method in the long tunnel.

Tunnel boring machine (TBM) is a large tunnel excavator that crushes rocks and grounds. It is a device that continuously rotates a cutter head equipped with a large number of disk cutters to perform excavation, buckle removal and support work.

Korean Patent No. 10-0981322 discloses such a TBM.

The most important part of the TBM is a rotating face plate (cutter head) as shown in Fig. 1, which is used to cut the actual ground.

In general, a disk cutter 2 as shown in Fig. 2 is mounted on the cutter head 1 corresponding to a rock.

The disc cutter 2 is composed of about 20 detailed parts including a cutter ring, a roller bearing, and the like.

A cutter ring (cutting portion) as shown in Fig. 3 is mounted on the disc cutter 2 by diameter. The cutter (hereinafter referred to as a "cutter") is a part that actually rotates as the TBM is operated and actually excavates the rock, which may wear or break as the drilling process proceeds. In this case, This causes a delay in construction or a delay in construction.

Therefore, measurement of the wear rate of the disk cutter 2 for grasping the replacement time of the disk cutter 2 is a very important technical matter.

In general, the wear rate of the disc cutter 2 is measured by using a wear gauge (FIG. 4). Since the position of the reference point of the wear gauge may vary due to wear, it is difficult to measure the wear degree.

The disc cutter 2 is used in combination with the cutter head 1. In this case, the disc cutter 2 is coupled to the cutter head 1 via a disc cutter cover 3 formed on both sides. The disk cutter cover 3 is not a portion that is in direct contact with the cutting surface, so that the disk cutter cover 3 is not worn through the cutting process.

Conventionally, as shown in Fig. 4, the wear rate is measured by bringing a separate wear gauge into close contact with the surface of the disk cutter 2. [ However, according to this conventional measurement method, the upper surface of the disc cutter 2, which is in contact with the wear gauge, is worn together with the cutter (cutter ring) 4 during the cutting operation, .

That is, the upper surface of the disk cutter 2 serving as the reference point is worn together with the cutting portion 4 to be subjected to the wear rate measurement, thereby causing a problem that the wear rate which is lower than the actual wear rate must be measured.

In order to solve the above-described problems, the apparatus for measuring the wear rate of a disk cutter according to the present invention provides an apparatus for measuring the wear rate of a disk cutter based on a disk cutter cover 3 which is not worn during a cutting operation.

The measurement groove 211 corresponds to a groove shape having a standard before the cutting portion 4 is worn. Therefore, when the cutting portion 4 having the abrasion phenomenon is inserted into the measuring groove 211, the space formed between the measuring groove 211 and the cutting portion 4 corresponds to the abrasion portion of the cutting portion 4. [

Therefore, the wear image of the disk cutter can be measured by acquiring the void image (c) regarding the space between the measurement groove 211 and the cutting portion 4 by using the photographing portion 220. [

Specific methods for measuring the wear rate of the disk cutter will be described later.

The photographing unit 220 includes a camera 221 for photographing an image and an extension unit 222 fixed to the joint unit 100 and supporting the camera 221 at a predetermined distance from the measurement reference unit 210 (Figs. 5 and 6).
