Description

Technical Field

[0001] This utility model relates to the field of cutter ring conveying technology, and in particular to the conveying structure of the cutter ring production line for tunnel boring machines. Background Technology

[0002] The cutterhead of a tunnel boring machine is equipped with thousands of cutting tools, among which the cutter ring is the core cutting component of the hobbing cutter, a type of cutter used for breaking rocks.

[0003] During the production and installation of cutter rings, it is inevitable to transport them between different production processes. Traditional conveyor structures are prone to cutter ring misalignment due to various factors, reducing the efficiency of subsequent transport and potentially causing the cutter rings to detach during transport, resulting in varying degrees of damage and affecting the quality of finished products. Traditional conveyor structures also struggle to achieve precise positioning and lifting of the cutter rings, further reducing efficiency when positioning and clamping them between different production processes. Furthermore, the extended disassembly time required for equipment maintenance increases downtime and impacts overall equipment efficiency. Utility Model Content

Through the operation program of the servo controller, the rotation direction and rotation angle of the output end of the first servo motor 5 are adjusted to effectively control the direction of rotation and provide driving force for the conveyor belt 3. This operation program is existing technology and will not be elaborated on here.

[0017] The detection sensor 2 is connected to the first servo motor 5. The output end of the first servo motor 5 is coaxially connected to the rotating shaft inside the conveyor belt 3. Through the cooperation of the detection sensor 2 and the first servo motor 5, the running status of the conveyor belt 3 is monitored to ensure the stability of the blade ring 6 during the conveying process, so that the blade ring 6 stops at the predetermined position, thus ensuring the efficiency of subsequent conveying of the blade ring 6.

[0018] A fixing groove 16 is provided at the end of the conveyor belt 3. An installation platform 14 is provided on the inner wall of the fixing groove 16. Limiting rods 12 are symmetrically provided on the conveyor belt 3 to limit the installation platform 14. Fixing blocks 13 are symmetrically fixed at the end of the conveyor belt 3. A sliding groove is provided in the fixing block 13. One end of the return spring 20 is fixedly provided on the inner wall of the sliding groove. The other end of the return spring 20 is fixedly provided on the end of the second moving block 21. The second moving block 21 is slidably provided on the inner wall of the sliding groove. The second moving block 21 and the limiting rod 12 are fixedly connected. Through the cooperation of the return spring 20 and the second moving block 21, the multiple limiting rods 12 limit the installation platform 14, which facilitates the subsequent disassembly and maintenance of the installation platform 14 by the operators and ensures the stability of the equipment during operation.

[0019] The mounting platform 14 is equipped with a placement tray 9, and a blade ring 6 is provided at the end of the placement tray 9. Electric telescopic rods 10 are symmetrically fixed at the end of the mounting platform 14. The output end of the electric telescopic rods 10 is fixedly connected to the bottom of the placement tray 9. The controller 15 is fixedly installed on the side wall of the mounting platform 14. Through the cooperation of the controller 15 and the electric telescopic rods 10, the multiple electric telescopic rods 10 drive the placement tray 9 to rise and fall, realizing the flexible adjustment of the height of the blade ring 6 during the conveying process, so as to meet the height requirements of different production processes for the blade ring 6 and ensure the stability of the blade ring 6 during transportation.

[0020] The mounting platform 14 is symmetrically provided with fixed rollers 17 for positioning the blade ring 6. The end of the placement tray 9 is provided with a movable hole, and the end of the fixed roller 17 extends out of the movable hole. The second servo motor 11 is fixedly installed on the side wall of the mounting platform 14. A shock-absorbing pad is provided between the second servo motor 11 and the mounting platform 14 to provide driving force for the conveyor belt 3. This operation procedure is existing technology and will not be described in detail here.

[0021] The mounting platform 14 has a groove, and a bidirectional lead screw 18 is provided on the inner side wall of the groove. The bidirectional lead screw 18 is rotatably mounted on the inner side wall of the groove. The output end of the second servo motor 11 is coaxially and fixedly connected to the end of the bidirectional lead screw 18. The outer side wall of the bidirectional lead screw 18 is symmetrically provided with a first moving block 19. The end of the first moving block 19 has a threaded hole that matches the bidirectional lead screw 18. The first moving block 19 moves on the bidirectional lead screw 18 through the threaded hole. The end of the first moving block 19 is fixedly connected to the bottom of the fixed roller 17. Through the cooperation of the first moving block 19 and the fixed roller 17, the multiple fixed rollers 17 position the cutter ring 6, ensuring that the cutter ring 6 will not deviate during the conveying process, thus improving the accuracy and stability of the conveying.

[0022] Multiple guide rods 8 are fixedly installed at the end of the mounting platform 14, and the guide rods 8 pass through the end of the placement tray 9. The limiting plate 7 is coaxially installed at the end of the guide rods 8. Through the cooperation of the guide rods 8 and the limiting plate 7, the lifting and lowering of the placement tray 9 is guided and limited, ensuring the stability of the placement tray 9 during the lifting and lowering process.

[0023] The functional principle of this utility model can be explained through the following operation methods: The position of the mounting platform 14 on the conveyor belt 3 is monitored by the detection sensor 2, and the first servo motor 5 is started. When the blade ring 6 reaches the designated position, the first servo motor 5 controls the conveyor belt 3 to stop running, ensuring that the blade ring 6 stops at the predetermined position. Multiple electric telescopic rods 10 are started by the controller 15. The electric telescopic rods 10 push the placement tray 9 to move along the guide rod 8. The limit plate 7 cooperates with the guide rod 8 to prevent the placement tray 9 from deviating during the lifting process. By starting the second servo motor 11, the second servo motor 11 drives the bidirectional lead screw 18 to rotate, and multiple first moving blocks 19 move on the outer wall of the bidirectional lead screw 18 through threaded holes, so that multiple fixed rollers 17 position and fix the cutter ring 6. When disassembly and maintenance are required, the operator moves the limit rod 12, which drives the second moving block 21 to move. The second moving block 21 squeezes the reset spring 20, releasing the limiting effect on the mounting platform 14, making it easier for the operator to disassemble and maintain the mounting platform 14.
