Figure 1 shows a top view of a tunnel boring machine tool loss detection arrangement in an embodiment of the present application.

Referring to fig. 1, an embodiment of the present invention provides a tunnel boring machine cutter loss detection device, which includes a detection piece 900, wherein the detection piece 900 is used for detecting the image of the shot cutter 800. In addition, the device further comprises a housing 100, a first driving member 200 and an image shooting member 300, wherein the first driving member 200 is connected to the inner wall of the housing 100 and is used for being detachably connected with the cutter 800. The image photographing member 300 is rotatably coupled to an inner wall of the housing 100 and serves to photograph an image of the cutter 800, and the image photographing member 300 has a photographing range. The image capturing unit 300 can rotate relative to the housing 100, and the first driving unit 200 can drive the cutter 800 to rotate around its axis in a connected state with the cutter 800, so that different regions on the cutter 800 can enter a capturing range.

Specifically, the image capture device 300 may be a camera or the like having a capturing function. The photographing range of the image photographing member 300 means that components within the range can be photographed by the image photographing member 300. The image shooting piece 300 is in communication connection with the detection piece 900, when detection is carried out, the image shooting piece 300 shoots the image of the cutter 800, and the detection piece 900 carries out detection and analysis on the shot image of the cutter 800, so that the abrasion condition of the cutter 800 can be known. Further, the wear condition includes, but is not limited to, wear location, wear size, wear shape, and the like. It should be noted that the detection and analysis method of the detection element 900 is the prior art, and is not described herein again.

Specifically, the housing 100 includes four sidewalls, the four sidewalls enclose a cavity, and the cutter 800, the first driving member 200, the image capturing member 300 and other components are located in the enclosed cavity. The housing 100 may have a top wall and a bottom wall, i.e., the top and the bottom are closed; the top wall and the bottom wall are not arranged, namely the top and the bottom are open. In the embodiment shown in the drawings, the housing 100 has four side walls, and also has a top wall and a bottom wall, the top wall being omitted from the view of the drawings. In the embodiment shown in the drawings, the image photographing member 300 is mounted to a sidewall of the housing 100. Of course, in other embodiments, the image capture device 300 may be mounted on the inner side of the top wall or the bottom wall of the housing 100.

Referring to fig. 1, in some embodiments, the wear-out detecting apparatus for the cutting tool 800 further includes a mounting base 400 connected to the inner wall of the housing 100, and the image capturing element 300 is connected to the mounting base 400 in a spherical hinge manner. Specifically, the mount 400 is fixedly coupled to an inner wall of the housing 100, and the image photographing member 300 is indirectly coupled to the housing 100 through the mount 400. Of course, in some embodiments, image capture object 300 may also be directly spherically hinged to the interior wall of housing 100. In some embodiments, the mounting block 400 is fixedly attached to the inner wall of the housing 100 by a threaded fastener such as a screw. In other embodiments, the fixing can be realized by clamping or magnetic attraction.

In this embodiment, the image capturing part 300 is connected to the mounting base 400 in a spherical hinge manner, so that the image capturing part 300 can rotate around multiple directions relative to the mounting base 400, and the shooting direction of the image capturing part 300 can be adjusted, so that the shooting range of the image capturing part can be adjusted, and the image capturing part can be aligned to different areas on the cutter 800, thereby more comprehensively acquiring images of all areas of the cutter 800, and facilitating improvement of the accuracy and the comprehensiveness of detection. Here, the photographing direction refers to a direction in which the image pickup device 300 faces the mounting position of the tool 800. In the view shown in the drawings, i.e., in a direction from the inner wall of the housing 100 toward the center position inside the housing 100.

In this embodiment, the rotation of the image capturing unit 300 with respect to the mount 400 may be adjusted before the start of the inspection, or may be adjusted during the inspection. As described above, the cutter 800 can be rotated by the first driving member 200 so that different regions thereof can enter the photographing range of the image photographing member 300. However, in some cases, no matter where the cutter 800 rotates, the cutter 800 still has a situation that a partial region cannot enter the shooting range, that is, a shooting blind region exists. Based on the above situation, the image capturing device 300 can rotate relative to the mounting base 400, so that the image capturing device can rotate to a better capturing angle, thereby reducing the capturing blind area, and capturing all areas on the tool 800 as comprehensively as possible under the condition that the first driving device 200 drives the tool 800 to rotate for one turn, thereby improving the capturing efficiency and the detection efficiency.

Alternatively, in some embodiments, the wear detection device of the tool 800 includes a second driving member connected to the inner wall of the housing 100, the second driving member being connected to the image capture element 300 and configured to drive the image capture element 300 to rotate during the detection process. Specifically, the second driving member may be a motor or a rotary cylinder. The image photographing member 300 is connected with a power output end of the second driving member to obtain power. Similar to the previous embodiment, the image capturing device 300 can be driven to rotate by the second driving device before the detection starts, so that the image capturing device 300 can rotate to a better capturing angle, and the capturing blind area can be reduced. The image capturing element 300 can also be driven to rotate by the second driving element during the detection process. Specifically, the second driving member may drive the image photographing member 300 to rotate in a vertical plane, or the second driving member may drive the image photographing member 300 to rotate in a horizontal plane. Alternatively, a driving module having two driving members may be provided, which can drive the image capturing unit 300 to rotate not only in a vertical plane but also in a horizontal plane.

With continued reference to fig. 1, in some embodiments, the wear detection apparatus for the tool 800 further includes a cantilever 500 extending from an inner wall of the housing 100, and the first driving member 200 is mounted on the cantilever 500. The cantilever 500 is rotatably connected to the inner wall of the housing 100, and the first driving member 200 can rotate with the cantilever 500 relative to the housing 100. Specifically, the cantilever 500 horizontally extends from the inner sidewall of the housing 100, and the cantilever 500 is rotatably connected to the inner sidewall, and the cantilever 500 can rotate in a horizontal plane relative to the rotatable connection. The first driving member 200 is fixedly connected to the free end of the cantilever 500 and can rotate synchronously with the cantilever 500. By rotating the arm 500 with respect to the housing 100, the position of the first driver 200 with respect to the image capture object 300 can be adjusted, thereby adjusting the position of the tool 800 mounted on the first driver 200 with respect to the image capture object 300. Similar to the rotation of the image capturing element 300 in the previous embodiment, the rotation of the cutter 800 in this embodiment can make the cutter 800 be located at a better position, so as to reduce blind areas, and to achieve a comprehensive capturing of each area on the cutter 800 under the condition that the first driving element 200 drives the cutter 800 to rotate for one turn, thereby improving the capturing efficiency and the detection efficiency.

Specifically, in some embodiments, the cantilever 500 is indirectly rotatably coupled to the inner wall of the housing 100 via the coupling member 600. The connecting member 600 is fixedly connected to the inner wall of the casing 100, and the suspension arm 500 is rotatably connected to the bottom end of the connecting member 600. Of course, the cantilever 500 may be directly rotatably connected to the inner wall of the housing 100.

With continued reference to fig. 1, in some embodiments, the cantilever 500 is configured as a telescopic rod capable of extending and retracting along its length. Specifically, the cantilever 500 may be a telescopic rod of any type known in the art. Similar to the previous embodiment, in the present embodiment, the tool 800 is located at a better position by the extension and retraction of the cantilever 500 along the length direction thereof, so as to reduce the dead zone, and achieve the purpose of performing a relatively comprehensive shooting on each area of the tool 800 under the condition that the first driving member 200 drives the tool 800 to rotate for one turn, thereby improving the shooting efficiency and the detection efficiency.

Fig. 4 shows a left side view of the housing in an embodiment of the present application.

Referring to fig. 1 and 4, in some embodiments, an avoiding hole 110 is formed on an inner wall of the housing 100, and the first driving member 200 and the cantilever 500 can rotate relative to the housing 100 to extend out of the housing 100 through the avoiding hole 110. Specifically, the escape hole 110 penetrates the housing 100. As previously described, the boom 500 is able to rotate in a horizontal plane relative to the rotational connection of the boom 500 to the housing 100. The first driving member 200 is fixedly connected to the free end of the cantilever 500 and can rotate synchronously with the cantilever 500. When the cantilever 500 and the first driving member 200 rotate toward the direction close to the inner wall of the housing 100, they will gradually approach the avoiding hole 110 until the cantilever 500 and the first driving member 200 extend out of the housing 100 through the avoiding hole 110, so that there is a relatively spacious space to implement the installation of the cutter 800. After the installation is completed, the cantilever 500 and the first driving member 200 are rotated reversely to enter the interior of the housing 100.

With reference to fig. 1 and fig. 4, in some embodiments, the avoiding hole 110 includes a first portion 111 and a second portion 112 communicating with the first portion 111, the size of the second portion 112 is larger than that of the first portion 111, and along the arrangement direction of the first portion 111 and the second portion 112, the first portion 111 is located at a side close to a connection position of the cantilever 500 and an inner wall of the housing 100, the first driving member 200 and the cantilever 500 can rotate relative to the housing 100 until the cantilever 500 extends out of the housing 100 through the first portion 111, and the first driving member 200 extends out of the housing 100 through the second portion 112.

Specifically, the first portion 111 has a size larger than that of the cantilever 500, and the second portion 112 has a size larger than that of the first driving member 200 after the tool 800 is mounted thereon. When the cantilever 500 rotates outwards, the cantilever can pass through the first part 111, and the first driving part 200 can pass through the second part 112; the first drive member 200 with the cutter 800 mounted thereon can pass through the second portion 112 as it is rotated inwardly. As shown, the arm 500 is rod-shaped and the tool 800 is similarly cylindrical, such that the first portion 111 is elongated and the second portion 112 is circular. Of course, in other embodiments, the first portion 111 and the second portion 112 may be configured in the same shape, for example, the first portion 111 may also be configured in the same size and shape as the second portion 112.

Fig. 3 shows a front view of a tool in an embodiment of the present application.

Referring to fig. 1 and 3, in some embodiments, the first driving member 200 includes an output shaft 210 for detachably connecting with a tool 800, and a plurality of image capturing members 300 are disposed around an outer side of the output shaft 210. Specifically, the output shaft 210 is located in a horizontal plane. The cutter 800 includes a body portion 810, and a blade portion is mounted on an outer circumferential surface of the body portion 810. The main body 810 has a mounting hole 811 formed at a center thereof and extending through the main body in an axial direction thereof, and the output shaft 210 passes through the mounting hole 811 and is engaged with the mounting hole to restrict relative rotation therebetween.

Specifically, in some embodiments, the outer circumferential surface of the output shaft 210 is provided with a projection protruding outward in the radial direction thereof, and correspondingly, the hole wall of the mounting hole 811 is provided with a groove recessed in the radial direction thereof. When the cutter 800 is installed, the axis of the cutter 800 is aligned with the axis of the output shaft 210, the cutter 800 moves towards the output shaft 210, and the convex block is clamped in the concave groove, so that the connection between the cutter 800 and the output shaft 210 is realized, namely, the installation is realized by adopting a mode similar to key matching. In other embodiments, the positions of the bumps and the grooves can be interchanged. In order to perform axial position limitation so as to prevent the cutter 800 from falling off from the output shaft 210 during the rotation process, a position limiting member 220 is further sleeved on the output shaft 210, and the position limiting member 220 blocks the end portion of the cutter 800 so as to limit the axial displacement of the cutter 800. The limiting member 220 may be a snap spring or the like.

Figure 2 shows a top view of a tunnel boring machine tool loss detection arrangement in another embodiment of the present application.

Referring to fig. 2, in some embodiments, a plurality of image capturing devices 300 are uniformly arranged around the output shaft 210. The direction in which the image pickup device 300 faces the output shaft 210 is set as a pickup direction, and at least a part of the image pickup devices 300 among the plurality of image pickup devices 300 is picked up in a different direction from the other image pickup devices 300. Specifically, the shooting orientation is a direction in which the image capture object 300 faces the tool 800. In fig. 2, 4 image capture objects 300 are provided, and the four image capture objects 300 are captured in different directions, and each image capture object 300 can capture a different area of the tool 800. By setting the plurality of image shooting pieces 300 to shoot different areas of the cutter 800 at the same time, the image of the cutter 800 can be obtained more comprehensively, so that the detection result is more comprehensive and accurate. In the embodiment shown in the drawings, 4 image capturing devices 300 are disposed on the inner side wall of the housing 100, and in other embodiments, a plurality of image capturing devices 300 may be additionally disposed on the top wall and/or the bottom wall of the housing 100.

Referring to fig. 1 and 2, in some embodiments, a transparent partition 700 is disposed at the front end of the image capturing device 300 along the capturing direction. Specifically, the transparent spacer 700 is made of a high-strength transparent material. The transparent partition 700 is disposed at the front end of the image capturing unit 300, so that the image capturing unit 300 can be protected from being damaged by falling off of the cutter 800 during rotation of the image capturing unit 300. Since the transparent partition 700 is transparent, it can protect the image capturing device 300 and does not affect the normal capturing of the image capturing device.

The detecting member 900 will be described below. In some embodiments, the detecting member 900 is provided with a display 910, a button 920, and a tachometer 930. The detector 900 and thus the first driving member 200 can be activated by pressing the button 920. The speed meter 930 is used to display the speed of the first driver 200. One of the display screens 910 is used to display the image captured by the image capturing device 300, and the other display screen 910 is used to display the wear status analyzed by the detecting device 900, such as the wear position, the wear size, the wear shape, etc. The detecting member 900 is connected to the image capturing member 300 through a wire 940, and the wire 940 passes through the wire through hole 120 provided on the housing 100 and is inserted into the slot on the detecting member 900 to achieve electrical connection and communication connection.
