Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, and in particular to a tunnel boring machine cutter wear detection device. Background Technology

[0002] Tunnel boring machines (TBMs) advance by cutting the soil with cutters on their cutterheads. During the tunneling process, the cutters inevitably experience impact and wear. The geological conditions at the TBM construction site vary, resulting in different levels of cutter wear. In some special soil layers, roller cutters are required to break up rocks. During this process, the roller cutters will suffer severe wear or damage due to impact. Cutter wear or cracks can affect the entire TBM construction process. Therefore, it is very important to detect the wear of various cutters on the TBM.

[0003] For example, patent document CN221222103U discloses a shield machine cutter wear detection device. During the detection process, the shield machine cutter is fixed and clamped by the pressure plate at the bottom of the positioning rod. After the cutter is fixed, the sliding base moves in a ring around the cutter, thereby driving the detection component to detect the wear of the cutter from multiple angles, which improves the safety of the detection process.

[0004] When the tunnel boring machine is working, the sides of the shield cutter are also impacted. However, in the process of using the above-mentioned patent, the angle of the detection camera cannot be changed when the shield cutter is being inspected, so other areas of the shield cutter cannot be inspected, and it is not convenient to inspect shield cutters of different sizes.

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a shield tunneling cutter wear detection device includes a base plate 1. A bearing column 101 is bolted to the bottom of the base plate 1. A storage groove 102 is provided on the top of the base plate 1. A first adjustment mechanism for adjusting the detection position and a stabilizing mechanism for improving detection stability are installed on the top of the base plate 1. The stabilizing mechanism is in front of the first adjustment mechanism. The first adjustment mechanism includes a sliding plate 206. A second adjustment mechanism for adjusting the detection angle is provided on the front side of the sliding plate 206. A fixing mechanism for fixing the detection equipment is installed on the front side of the second adjustment mechanism. A rotating mechanism for self-rotation is provided on the base plate 1. Two sets of clamping mechanisms for clamping and fixing are symmetrically installed on the top of the rotating mechanism.

[0026] The fixing mechanism includes a mounting plate 401, which is bolted to the front of the connecting plate 303. A bidirectional lead screw 402 is mounted on the front of the mounting plate 401 via a bearing seat. Two threaded blocks 403 are threadedly connected to the bidirectional lead screw 402. A shelf 404 is bolted to the front of the mounting plate 401. A sliding groove 405 is provided on the front of the shelf 404. The threaded blocks 403 are slidably connected in the sliding groove 405. A camera 406 is held between the two threaded blocks 403. The camera 406 is first placed between the two threaded blocks 403. Then, the bidirectional lead screw 402 is rotated by a turntable, thereby driving the two threaded blocks 403 to move closer to each other along the sliding groove 405, thus clamping and fixing the camera 406, achieving installation.

[0027] The clamping mechanism includes a cylinder 601, which is bolted to the top of the rotating disk 502. A rectangular plate 602 is threaded onto the output shaft of the cylinder 601. Two wedge blocks 603 are bolted to one side of the rectangular plate 602, arranged in a V-shape. The shield cutter to be inspected is placed on the top of the rotating disk 502, with one end of the cutter positioned in the positioning groove 506. Then, the two cylinders 601 operate, causing the two rectangular plates 602 to move closer together, thereby causing the two sets of wedge blocks 603 to move closer together, thus clamping and fixing one end of the shield cutter. The stabilizing mechanism includes two vertical plates 701, which are welded together. At the top of the base plate 1, the top of the vertical plate 701 is bolted to the top plate 702, and the bottom of the top plate 702 is bolted to the bottom of the hydraulic cylinder 703. The output shaft of the hydraulic cylinder 703 is threaded to the lifting plate 704, which is slidably connected to the inner wall of the two vertical plates 701. The bottom of the lifting plate 704 is rotatably connected to the pressure plate 705 through the bearing. The bottom center of the pressure plate 705 has a limit groove 706. When the hydraulic cylinder 703 works, it drives the lifting plate 704 to move down along the inner wall of the two vertical plates 701, thereby driving the pressure plate 705 down until the limit groove 706 is pressed down to the other end of the shield cutter, thereby stabilizing the shield cutter.

[0028] The first adjustment mechanism includes a fixed plate 201, which is welded to the top of the base plate 1. A transmission screw 202 is mounted on the front side of the fixed plate 201 via a bearing seat. A sliding block 203 is threaded onto the transmission screw 202 and slidably connected to the front side of the fixed plate 201. A fixed frame 204 is bolted to the front side of the sliding block 203, and an electric actuator 205 is bolted to the fixed frame 204. A sliding plate 206 is threaded onto the output shaft of the electric actuator 205 and slidably connected to the inner wall of the fixed frame 204. By rotating the transmission screw 202 via a turntable, the sliding block 203 is driven to move up and down, which in turn drives the fixed frame 204 to move up and down. The movement of the fixed frame 204 drives the second adjustment mechanism and the fixed mechanism to move up and down, thereby adjusting the height of the camera 406. Then, the operation of the electric actuator 205 drives the sliding plate 206 to move along the fixed frame 204. The inner wall slides, thereby driving the second adjustment mechanism and the fixing mechanism to move back and forth, thus adjusting the distance between the camera 406 and the shield cutter for easy detection. The rotating mechanism includes a fixed plate 501, which is bolted to the base plate 1. A rotating plate 502 is rotatably connected to the fixed plate 501 via bearings. A support frame 503 is bolted to the bottom of the base plate 1. A second motor 504 is bolted to the support frame 503. A transition plate 505 is keyed to the output shaft of the second motor 504. The top of the transition plate 505 is bolted to the rotating plate 502. A positioning groove 506 is provided at the center of the top of the rotating plate 502. When the second motor 504 works, it drives the transition plate 505 to rotate, thereby driving the rotating plate 502 to rotate in the fixed plate 501, and thus driving the shield cutter held by the two sets of clamping mechanisms to rotate, realizing all-round wear detection of the shield cutter.

[0029] The second adjustment mechanism includes a mounting frame 301, which is bolted to the front of the sliding plate 206. A rotating shaft 302 is rotatably connected to the mounting frame 301 via bearings. A connecting plate 303 is connected to the rotating shaft 302 via a key. A first motor 304 is bolted to the outer wall of one end of the mounting frame 301. A first gear 305 is connected to the output shaft of the first motor 304 via a key. One end of the rotating shaft 302 extends out of the mounting frame 301 and is connected to a second gear 306 via a key. The first gear 305 and the second gear 306 mesh. When different areas of the shield cutter need to be detected, the first motor 304 operates, driving the first gear 305 to rotate, thereby driving the second gear 306 to rotate, which in turn drives the rotating shaft 302 to rotate within the mounting frame 301. The rotation of the rotating shaft 302 drives the fixing mechanism to rotate, thereby causing the camera 406 to rotate at a certain angle, thus adjusting the detection area. In conjunction with the first adjustment mechanism and the rotating mechanism, it enables precise detection of other areas of the shield cutter.

[0030] Working principle: In use, the camera 406 is first placed between two threaded blocks 403. Then, the double-acting screw 402 is rotated by the turntable, thereby driving the two threaded blocks 403 to move closer together along the sliding groove 405, thus clamping and fixing the camera 406, achieving installation. Then, the shield cutter to be tested is placed on the top of the rotating disk 502, with one end of the cutter located in the positioning groove 506. Next, the two cylinders 601 work, driving the two rectangular plates 602 to move closer together, thereby driving the two sets of wedge blocks 603 to move closer together, thus clamping and fixing the shield. One end of the cutter is then driven by a hydraulic cylinder 703, which moves the lifting plate 704 down along the inner wall of the two vertical plates 701, thereby moving the pressure plate 705 down until the limiting groove 706 is pressed down to the other end of the shield cutter, thus stabilizing the shield cutter. Then, the turntable rotates the transmission screw 202, which drives the sliding block 203 to move up and down, thereby moving the fixing frame 204 up and down. The movement of the fixing frame 204 drives the second adjustment mechanism and the fixing mechanism to move up and down, thereby adjusting the height of the camera 406. Finally, the electric push rod 205 drives the sliding block 203 to move up and down. The sliding plate 206 slides along the inner wall of the fixed frame 204, thereby driving the second adjustment mechanism and the fixing mechanism to move back and forth, thus adjusting the distance between the camera 406 and the shield cutter for easier detection. After adjustment, the second motor 504 operates, driving the adapter plate 505 to rotate, thereby driving the rotating disk 502 to rotate in the fixed disk 501, which in turn drives the shield cutter held by the two sets of clamping mechanisms to rotate, realizing all-round wear detection of the shield cutter. The two sets of wedge blocks 603 can clamp and fix shield cutters of different sizes, and are equipped with... The first adjustment mechanism adjusts the position of the camera 406, enabling the detection of cutters of different sizes. When different areas of the shield cutter need to be detected, the first motor 304 operates, driving the first gear 305 to rotate, which in turn drives the second gear 306 to rotate, thereby driving the rotating shaft 302 to rotate in the mounting bracket 301. The rotation of the rotating shaft 302 drives the fixing mechanism to rotate, thereby causing the camera 406 to rotate at a certain angle, thus adjusting the detection area. In conjunction with the first adjustment mechanism and the rotating mechanism, it enables precise detection of other areas of the shield cutter.
