During the tunnel construction process, the disc hob is the core component for the tunneling machine to perform rock breaking work, and is subjected to strong extrusion and cutting effects from rock and soil. Due to the complex and changeable geology, the disc hob has a large loss during the construction process.

Therefore, it has all the beneficial technical effects of the disc cutter wear detection system, and will not be elaborated here.

[0012] In the above technical solution, further, the method for detecting the wear amount of a disc cutter includes the following steps:

[0013] Spread the colored putty in the bearing groove to make its surface smooth and flat.

[0014] Install the disc cutter to be detected on the rotating member, and adjust the height of the rotating member so that the cutting edge of the disc cutter just immerses into the colored putty, and make a mark on the top of the disc cutter.

[0015] Start the driving device, and at the same time move the bearing groove until the marked part of the disc cutter returns to the original position, then turn off the driving device and stop moving the putty groove.

[0073] The rotating member 2 is raised, the disc-shaped roller cutter 12 is removed from the bearing groove 4, and the scanning device 6 is turned on to obtain the profile of the disc-shaped roller cutter 12;

[0074] According to the above steps, the profile information of the disc cutter 12 before and after wear is obtained respectively, and then the wear amount of the disc cutter 12 in the cutter ring diameter direction and the wear amount of the disc cutter 12 in the cutter ring thickness direction are analyzed and calculated respectively, and classified and managed.

[0075] According to the above description, the worn disc cutter 12 can be accurately measured by using this method, so as to effectively detect the wear values in the diameter direction and thickness direction of the disc cutter 12, avoiding the defects of large workload and inaccuracy in manual judgment.

[0077] When it is necessary to analyze and calculate the wear amount in the thickness direction of the cutter ring of the disc cutter 12, on the root contour curve of the cutting edge of the disc cutter 12, a measurement point is set at an average interval of a preset distance (and preferably, a measurement point is set at an average interval of 3 - 5 mm), and a total of n measurement points are set; the indentation width of the first measurement point of the disc cutter 12 on the colored putty 5 before wear is taken as D1, and the indentation width of the first measurement point of the disc cutter 12 on the colored putty 5 after wear is taken as d1, then the wear amount L1 of the first measurement point = D1 - d1, and the wear amount L at the nth measurement point n = D n - d n 。

[0078] On the basis of the data obtained above, according to the wear amounts in the diameter direction of the cutter ring at n measuring points measured for the same hob, calculate the maximum value S max 、S min 、average value S 平 、variance S 2 ;

[0083] Embodiment 3

[0084] See Figure 1 and Figure 2 shown. Embodiment 3 of the present application also provides a method for detecting the wear amount of a disc cutter, using the disc cutter wear amount detection system described in Embodiment 1 above, including the following steps:

[0085] Spread the colored putty 5 in the bearing groove 4 to make its surface smooth and flat;

[0086] Install the disc cutter 12 to be detected on the rotating member 2, and adjust the height of the rotating member 2 so that the cutting edge of the disc cutter 12 just sinks into the colored putty 5, and make a mark on the top of the disc cutter 12;

[0087] Start the driving device 3. At the same time, move the bearing groove 4 (and preferably, the translational sliding speed of the bearing groove 4 is the same as the linear speed of the contact point between the disc cutter 12 and the colored putty 5) until the marked part of the disc cutter 12 returns to its original position, turn off the driving device 3, and stop moving the putty groove;

[0088] Lift the rotating member 2 to remove the disc hob 12 from the bearing groove 4, and turn on the scanning device 6 to obtain the contour of the disc hob 12.

[0089] Obtain the contour information of the disc hob 12 before and after wear respectively according to the above steps, and then visually judge the wear condition of the hob.

[0090] Note: Further, preferably, as Figure 4 shown, two contour lines, that is, the contour lines before and after wear, are formed at intervals along the width direction on the same sludge tank, which is convenient for visual comparison.

[0091] According to the above description, for the complex profiles before and after wear, compare the width and depth of the indentation. Compared with the width and depth of the indentation before wear, the shallower the indentation depth and the narrower the indentation width after wear, the more serious the hob wear; if the width direction of the indentation suddenly becomes extremely narrow, it can be judged that the cutting edge is broken.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
