Description

Technical Field

[0001] The invention relates to the technical field of shield tunnel engineering, and in particular to an electromagnetically driven shield machine rotation movement system and an application method. Background Art

[0002] Urban rail transit projects are generally carried out in cities, and the shield construction site is small. Due to the limitation of site space, one shield machine is generally used to construct a tunnel first; after the shield machine exits the tunnel, the shield body of the shield machine is disassembled, and a large crane is used to lift it to the starting bracket of another tunnel. After the shield body is reassembled and debugged, the initial excavation is carried out. There are a series of problems with the shield machine transfer plan, as follows: 1) Low construction efficiency. Generally, it takes at least 2 months to disassemble, lift, assemble and debug the shield machine; 2) High safety risk. A large crane is required to lift the shield machine, and the safety risk is high during the lifting process; 3) High construction cost, high crane rental fee, long construction period and high cost. Therefore, research on the rotation and movement of shield machines has important social and economic benefits.

[0003] At present, the research status and problems of shield machine rotation and movement technology by industry insiders are roughly as follows: 1) Using hydraulic cylinders to push the shield machine to achieve the rotation and movement of the shield machine; this solution requires the temporary installation of hydraulic cylinders, and a reaction device needs to be added at the rear end of the hydraulic cylinder; in addition, when the shield machine rotates, it is necessary to change the position of the reaction device and the length of the hydraulic cylinder in real time, which greatly reduces the construction efficiency; 2) Using electric vehicles to tow the shield machine to achieve the rotation and movement of the shield machine; due to the large mass of the shield machine, using electric vehicles to tow it requires very large traction, huge battery consumption, high cost, and the narrow clearance size of the receiving shaft. During actual construction, there is no space for the electric vehicle to tow the shield machine to turn; 3) Installing a motor on the bracket to drive the shield machine to move; due to the small size of the bracket, it is not convenient to install the motor, and the problem of shield machine steering cannot be solved; in addition, the motor power is too large, the construction safety risk is high, and the cost is high.

[0004] In summary, it is necessary to provide an electromagnetically driven shield machine rotation and movement system and application method to solve the problems of low construction efficiency, high construction safety risks and high costs in the existing shield machine rotation and movement technology.

An application method of the electromagnetic driven shield machine rotation and movement system as claimed in claim 9, characterized in that: include: Step S1, hoisting the bracket mechanism (1) onto the track (3) in the receiving well near the opening of the right line (B) of the shield tunnel, and at the same time, adjusting the bracket mechanism (1) to an initial state, that is, adjusting to a state where the permanent magnets (2) on both sides of the bracket mechanism (1) and the electric induction magnets (5) on the two corresponding vertical plates (4) are dislocated; introducing the shield machine (A) after the operation on the right line (B) of the shield tunnel is completed onto the bracket mechanism (1) under the action of the rear supporting trolley, and disconnecting the pipelines and cables connected to the shield machine (A); Step S2, first, the switch on the first conductor is closed by the PLC controller to pass alternating current to each of the induction magnets (5) in the first straight area (6) to generate an alternating magnetic field; in the initial misaligned state, by means of the magnetic force of the opposite magnetic poles between the induction magnets (5) and the permanent magnets (2), a combined force can be formed to pull the bracket mechanism (1) to carry the shield machine (A) on the track (3); Secondly, the switch on the second conductor is closed by the PLC controller to pass alternating current into each of the inductive magnets (5) in the second linear area (8) to generate an alternating magnetic field, which continuously gathers a combined force to pull the bracket mechanism (1) to carry the shield machine (A) on the track (3), thereby completing the first rotation action of the shield machine (A); Subsequently, the switch on the third conductor is closed by the PLC controller, so as to supply alternating current to each of the inductive magnets (5) in the third linear region to generate an alternating magnetic field, and continuously form a combined force to pull the bracket mechanism (1) to carry the shield machine (A) on the track (3); wherein, when the PLC controller closes the switch on the third conductor, the switch on the first conductor and the switch on the second conductor are opened; Then, the switch on the fourth conductor is closed by the PLC controller to supply alternating current to each of the inductive magnets (5) in the fourth linear region to generate an alternating magnetic field, thereby continuously gathering a combined force to pull the bracket mechanism (1) to carry the shield machine (A) on the track (3), thereby completing the second rotation of the shield machine (A); Finally, the switch on the fifth conductor is closed by the PLC controller, so as to supply alternating current to each of the inductive magnets (5) in the fifth linear region to generate an alternating magnetic field, and continuously form a combined force to pull the bracket mechanism (1) to carry the shield machine (A) on the track (3); wherein, when the PLC controller closes the switch on the fifth conductor, the switch on the third conductor is opened; When the bracket mechanism (1) carries the shield machine (A) on the track (3) to a position in the receiving shaft close to the opening of the left line (C) of the shield tunnel, the PLC controller disconnects the switch on the fourth wire and the switch on the fifth wire; When the shield machine (A) completes the rotational movement along with the bracket mechanism (1), the PLC controller controls the magnitude of the alternating current connected by the AC power supply to each of the induction magnets (5), thereby controlling the speed of the rotational movement of the shield machine (A).
