Embodiment 1

[0048] as attached Figure 1-4 As shown, a disc-shaped hob wear classification detection device for a roadheader includes a detection platform 1 and a telescopic mechanical arm 2 vertically arranged on one side of the detection platform 1; the detection platform 1 is provided with a 12 clamping assembly; the upper end of the telescopic mechanical arm 2 is provided with a first rotating mechanical arm 3 for horizontal rotation around the axis of the telescopic mechanical arm 2, and the other end of the first rotating mechanical arm 3 is provided There is a vertical second rotating mechanical arm 4, and the second rotating mechanical arm 4 is used to rotate horizontally around its axis; the lower end of the second rotating mechanical arm 4 is provided with a horizontal mounting plate 5, and the horizontal mounting plate 5 is provided with a moving mechanism for moving left and right along the horizontal mounting plate 5; a camera with a turning mechanism is arranged below the mo...

Embodiment 2

[0054] This embodiment uses the classification detection device in Embodiment 1 to carry out the classification detection method for the wear of the disc-shaped hob of the roadheader. This embodiment is a low-precision detection method for the wear of the disc-shaped hob, which specifically includes the following steps:

[0055] a. Turn the camera 18 to a position away from the detection platform 1 through the first rotating mechanical arm 3, then place the cutter shaft of the disc hob 12 to be detected between the two clamping plates 13, and start the third motor 15 Until the cutter shaft of the disc-shaped hob 12 is clamped;

[0056] b, start the first rotating mechanical arm 3 to rotate the camera 18 to the top of the disc hob 12, start the first motor 6, adjust the camera 18 to the axis line of the second rotating mechanical arm 4 and the disc hob The axis lines of the cutter shafts of 12 overlap, and the camera 18 is positioned directly above the disc hob 12; according to...

Embodiment 3

[0065] This embodiment uses the classification detection device in Embodiment 1 to carry out the classification detection method for the disc hob wear of the roadheader. This embodiment is a high-precision detection method for the wear amount of the disc hob. The difference between this embodiment and Embodiment 2 in:

[0066] The method of adjusting the position of the camera in step b is different, and the method of shooting the photo in step d is different.

[0067] Step b in this embodiment includes the following steps: use the first rotating mechanical arm 3 to rotate the camera 18 to the top of the disc-shaped hob 12, to the axis line of the second rotating mechanical arm 4 and the disc-shaped hob 12 coincide between the axes of the cutter shafts; then start the first motor 6 and move the camera 18 along the horizontal groove 7 until the camera 18 moves directly above the edge of the disc hob 12 cutter ring; according to the accuracy requirements of the detection and Th...

Description

technical field [0001] The patent of the present invention relates to the technical field of wear detection of disc-shaped hobs of roadheaders, in particular to a classification detection device and a classification detection method for wear of disc-shaped hobs of roadheaders. Background technique [0002] With the rapid development of my country's transportation industry, tunnel boring machines have been more and more widely used in the field of tunnel construction. In the process of tunnel construction, the disc hob is one of the key factors to ensure the safe and efficient construction of the roadheader. Due to the complex and changeable geology, the hobs are greatly lost during the construction process, the number is large and the cost is expensive, which directly affects the construction efficiency and construction cost. Hob wear is the most important form of damage. Therefore, it is necessary to detect and measure hob wear in a timely manner, save and classify managem...
