Description

Technical Field

[0001] This utility model relates to the field of cutterhead cake detection technology, and in particular to a quick-installation cutterhead cake real-time detection device. Background Technology

[0002] Mud cake buildup on the cutterhead poses a significant hazard during tunnel boring machine (TBM) construction. Mud cake buildup increases the rotational resistance of the cutterhead, causing a surge in the TBM's thrust and torque, leading to cutterhead overheating, cutter wear, and in severe cases, equipment jamming. This necessitates downtime for repairs, incurring high maintenance costs, delaying the project, and threatening tunnel construction safety. Therefore, real-time detection of cutterhead mud cake is essential for timely removal when it appears.

[0003] The existing cutterhead lacks a conveniently installed cake detection structure, and the real-time detection efficiency and practicality of cake formation on the cutterhead need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a quick-installation cutterhead cake detection device that can be flexibly and conveniently installed on existing cutterheads, and can conveniently and efficiently detect the cake formation on the cutterheads, with high detection efficiency and strong practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-installation cutter head mud cake real-time detection device includes a cutter head, with multiple detectors installed on the inner wall of the cutter head's through groove. Each detector includes a base, and a movable seat is slidably installed in a mounting hole at the end of the base. A bracket is provided inside the movable seat, and an integrated circuit board is engaged in the mounting groove of the bracket. An inner detection seat is engaged in the inner end face of the movable seat, and a detection ball is movably installed at the end of the inner detection seat. An infrared transceiver is installed on the inner end face of the movable seat, and the infrared transceiver is electrically connected to the integrated circuit board. A universal ball is installed at the port of the movable seat, and the detection ball is in contact with the surface of the universal ball.

[0007] By adopting the above technical solution, it can be easily installed on the existing cutter head, and at the same time, it can efficiently and sensitively detect the condition of mud cake on the cutter head, with high detection efficiency.

[0008] Furthermore, the surface of the detection ball is coated with multiple reflective and matte coatings, which are distributed alternately.

[0009] By adopting the above technical solution, the rotation of the detection ball can be effectively determined.

[0010] Furthermore, the integrated circuit board is equipped with a microprocessor, a radio frequency transmitter, an antenna, and a counting module, and the infrared light emitted by the infrared transceiver's transmitter illuminates the surface of the detection ball.

[0011] By adopting the above technical solution, the rotation of the detection ball can be effectively detected and counted, and then the count is transmitted to the receiving end.

[0012] Furthermore, an inner mounting base is engaged with the inner end face of the base, and a switch is fixedly mounted on the inner end face of the inner mounting base. The trigger rod of the switch passes through a through hole on the outer surface of the inner mounting base. A storage battery is installed inside the inner side of the inner mounting base, and the storage battery, switch, and integrated circuit board are connected in series.

[0013] By adopting the above technical solutions, the circuit can be controlled according to the actual situation.

[0014] Furthermore, a spring is provided inside the base, with both ends of the spring abutting against the end faces of the inner mounting base and the movable base, respectively, and a limit ring is installed at the mounting hole port of the base.

[0015] By adopting the above technical solution, it is ensured that the movable seat can effectively slide within the mounting holes of the base.

[0016] Furthermore, a receiver is provided on the outside of the cutter head, and the receiver is wirelessly connected to the integrated circuit board.

[0017] By adopting the above technical solution, the data transmitted by the detector can be effectively received, making it convenient for staff to view intuitively.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model can be flexibly installed on an existing cutterhead. When the cutterhead rotates, the universal ball against the digging surface rotates, and at the same time, the detection ball in contact with the surface of the universal ball rotates. Because multiple reflective and matte coatings are coated on the surface of the detection ball, and the reflective and matte coatings are alternately distributed, the infrared light emitted by the infrared transceiver irradiates the surface of the detection ball. Therefore, the rotation of the detection ball can effectively change the position of the reflective and matte coatings. During this process, the infrared light irradiates the receiving end of the infrared transceiver, which is irradiated by the infrared light reflected from the surface of the reflective coating. At this time, the infrared transceiver generates a signal. When the reflective and matte coatings change position, the infrared transceiver continuously generates electrical signals. At this time, the counting module on the integrated circuit board can effectively count the signals. After processing by the microprocessor, the radio frequency transmitter and antenna transmit the data to the receiver in real time. The operator of the tunnel boring machine can check the values ​​on the receiver in real time. If the values ​​do not change for a long time, it indicates that the universal ball is not rotating. Since multiple detectors are installed on the cutterhead at different positions, when multiple universal balls do not rotate, it is determined that mud cake has formed on the surface of the cutterhead. This method is highly practical.

[0020] 2. This utility model, by installing a spring, switch, battery, and slidingly mounted movable seat inside the base, ensures that when the cutterhead abuts against the digging surface, one end of the movable seat is stressed, the spring is compressed, and one end of the movable seat contacts the trigger rod of the switch, causing the switch to close. At this time, the battery supplies power to the integrated circuit board. When the cutterhead is not in contact with the digging surface, the spring causes the movable seat to no longer contact the switch contact rod, the switch opens, and the battery no longer outputs power. This effectively achieves energy-saving operation, effectively increases the working time of the device, and further improves its practicality. Attached Figure Description

[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4A quick-installation cutter head mud cake real-time detection device includes a cutter head 1. Multiple detectors 2 are installed on the inner wall of the through groove of the cutter head 1. Each detector 2 includes a base 4. A movable seat 5 is slidably installed in a mounting hole at the end of the base 4. A bracket is provided inside the movable seat 5, and an integrated circuit board 12 is engaged in the mounting groove of the bracket. An inner detection seat 13 is engaged in the inner end face of the movable seat 5. A detection ball 14 is movably installed at the end of the inner detection seat 13. An infrared transceiver 15 is installed on the inner end face of the movable seat 5 and is electrically connected to the integrated circuit board 12. The port of the movable seat 5... A universal ball 7 is installed at the location, and a detection ball 14 contacts the surface of the universal ball 7. The surface of the detection ball 14 is coated with multiple reflective coatings 16 and matte coatings 17, which are alternately distributed. The integrated circuit board 12 is equipped with a microprocessor, an RF transmitter, an antenna, and a counting module. Infrared light emitted from the transmitter of the infrared transceiver 15 shines on the surface of the detection ball 14. A receiver 3 is installed on the outside of the cutter head 1, and the receiver 3 is wirelessly connected to the integrated circuit board 12. It can be flexibly installed on the existing cutter head 1. When the cutter head 1 rotates, the universal ball 7 against the digging surface rotates. At this time, the detection ball 14, which is in contact with the surface of the omnidirectional ball 7, rotates. Since multiple reflective coatings 16 and matte coatings 17 are coated on the surface of the detection ball 14, and these coatings are alternately distributed, the infrared light emitted by the infrared transceiver 15 illuminates the surface of the detection ball 14. Therefore, the rotation of the detection ball 14 effectively changes the position of the reflective coatings 16 and matte coatings 17. During this process, the infrared light illuminates the receiving end of the infrared transceiver 15, which is illuminated by the infrared light reflected from the surface of the reflective coating 16. At this time, the infrared transceiver 15 generates an electrical signal. When the reflective coating 16 and the matte coating 17... When the position of coating 17 changes, infrared transceiver 15 will continuously generate electrical signals. At this time, the counting module on integrated circuit board 12 can effectively count. After processing by microprocessor, radio frequency transmitter and antenna transmit data to receiver 3 in real time. The operator of the tunnel boring machine can check the value on receiver 3 in real time. When the value does not change for a long time, it indicates that the universal ball 7 is not rotating. Since multiple detectors 2 are installed on cutterhead 1 at different positions, when multiple universal balls 7 do not rotate, it is determined that mud cake has formed on the surface of cutterhead 1. It is highly practical.

[0028] Reference Figure 3An inner mounting base 8 is fitted onto the inner end face of the base 4. A switch 9 is fixedly mounted on the inner end face of the inner mounting base 8. The trigger rod of the switch 9 passes through a through hole on the outer surface of the inner mounting base 8. A storage battery 10 is installed inside the inner mounting base 8. The storage battery 10, switch 9, and integrated circuit board 12 are connected in series. A spring 11 is installed inside the base 4. The two ends of the spring 11 abut against the end faces of the inner mounting base 8 and the movable base 5, respectively. A limit ring 6 is installed at the mounting hole port of the base 4. The system is designed to function by installing the spring 11, switch 9, and integrated circuit board 12 inside the base 4. When the cutterhead 1 is against the digging surface, one end of the movable seat 5 is subjected to force, the spring 11 is compressed, and one end of the movable seat 5 contacts the trigger rod of the switch 9, causing the switch 9 to close. At this time, the battery 10 supplies power to the integrated circuit board 12. When the cutterhead 1 is not in contact with the digging surface, the spring 11 causes the movable seat 5 to no longer contact the trigger rod of the switch 9, the switch 9 is opened, and the battery 10 no longer outputs power. This can effectively achieve energy-saving operation, effectively increase the working time of the device, and further improve its practicality.

[0029] Working principle: In use, multiple detectors 2 are first installed at different positions on the cutterhead 1. Then, when the cutterhead 1 is in contact with the digging surface, one end of the movable seat 5 abuts against the digging surface, and the spring 11 is compressed. One end of the movable seat 5 contacts the trigger rod of the switch 9, causing the switch 9 to close. At this time, the battery 10 supplies power to the integrated circuit board 12. When the cutterhead 1 rotates, the universal ball 7 against the digging surface rotates. At this time, the detection ball 14, which is in contact with the surface of the universal ball 7, rotates. Since multiple reflective coatings 16 and matte coatings 17 are coated on the surface of the detection ball 14, and the reflective coatings 16 and matte coatings 17 are alternately distributed, the infrared light emitted by the infrared transceiver 15 irradiates the surface of the detection ball 14. Therefore, the rotation of the detection ball 14 can effectively change the position of the reflective coatings 16 and matte coatings 17. During this process, the infrared light irradiated by the reflective coating 16 reflects the infrared light reflected from the surface of the reflective coating 16. The infrared transceiver 15 receives the signal. At this time, the infrared transceiver 15 generates an electrical signal. When the reflective coating 16 and the matte coating 17 change position, the infrared transceiver 15 will continuously generate electrical signals. At this time, the counting module on the integrated circuit board 12 can effectively count. After processing by the microprocessor, the radio frequency transmitter and antenna transmit the data to the receiver 3 in real time. The operator of the tunnel boring machine can check the value on the receiver 3 in real time. When the value does not change for a long time, it indicates that the universal ball 7 is not rotating. Since multiple detectors 2 are installed on the cutterhead 1, and the detectors 2 are installed at different positions on the cutterhead 1, when multiple universal balls 7 do not rotate, it is determined that mud cake has formed on the surface of the cutterhead 1. When the cutterhead 1 is not in contact with the excavation face, the spring 11 makes the movable seat 5 no longer in contact with the contact rod of the switch 9, the switch 9 is open, and the battery 10 no longer outputs power. This can effectively achieve energy-saving operation.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
