Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary center maintenance training technology, specifically a rotary center maintenance platform for learning and training. Background Technology
[0002] The central rotating body of the tunnel boring machine (TBM) is a key component located between the soil chamber partition and the main drive. It mainly consists of a stator and a rotor. The stator is connected to the stationary components, while the rotor rotates with the cutterhead. Its function is to supply the soil chamber and cutterhead with soil amendment materials, hydraulic oil for the cutting tool, and sealing oil for the tool wear device, among other liquid substances. It has various internal fluid channels, and a complex sealing structure ensures that each channel is independent and leak-proof, guaranteeing the normal tunneling operation of the TBM. The central rotating body has contour guide pipes, mud filling pipes, and lubrication pipes. The contour guide pipes provide hydraulic control channels for the contour cutterhead, allowing the cutterhead to extend, retract, and oscillate according to construction needs, thereby achieving contour cutting of the tunnel cross-section. The mud filling pipes supply soil or slurry to the excavation face in front of the cutterhead, reaching the cutterhead through channels inside the central rotating body. This improves the soil properties at the excavation face, giving it better fluidity and water-stopping properties, and reducing tool wear. Lubrication pipes: These provide lubrication to all rotating parts of the central rotating body. Lubrication points are set at key locations on the central rotating body to deliver lubricating oil to the areas requiring lubrication. Currently, to help students better understand the malfunctions of the central rotating body and ensure effective training, a simulated testing platform is used to simulate malfunctions in the central rotating body's operation for student learning purposes.
[0003] For example, prior art application number CN202022120151.4 discloses an experimental platform for simulating and detecting the slewing center of a tunnel boring machine, including a base, a motor, a reducer, a coupling, and a central slewing body. The motor is fixedly installed on one side of the upper end of the base, and the output end of the motor is connected to the reducer via a transmission shaft. The central slewing body is fixedly installed on the other side of the upper end of the base, and the output end of the central slewing body is connected to the output end of the reducer via a coupling. Limit bearings are provided on the outer periphery of both ends of the coupling, and the limit bearings include an inner ring, an outer ring, and bearing balls.
[0004] The existing technology described above has been found through practical use to have a relatively simple fault simulation, which cannot flexibly adapt to the needs of various fault learning scenarios and is difficult to cultivate professional talents that meet the actual production needs; therefore, we have improved the existing technology based on actual usage.

A temperature sensor, a pressure sensor, and a speed sensor are installed inside the central rotary body. A motor speed controller and a display screen are installed on one side of the motor.
[0009] Furthermore, the upper end of the base is fixed with a mounting bracket to the motor and the central rotating body, and the output end of the motor is equipped with a reducer, and the output end of the reducer is equipped with the central rotating body through a coupling.
[0010] Furthermore, the upper end of the base is fixed to the display screen by a bracket, and a switch is also provided on the upper end of the base.
[0011] Furthermore, the motor speed controller connection terminal is electrically connected to the positive and negative terminals of the motor via wires.
[0012] Furthermore, the rotating valve body of the solenoid valve is provided with a through hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In use, the motor drives the central rotating body by starting the switch. The motor speed controller can change the speed of the motor and the central rotating body to study the operating characteristics of the device under different speed faults. At the same time, solenoid valves are installed in the mud filling pipe, lubrication pipe and conformal guide pipe. The flow of the pipes is controlled by the solenoid valves to simulate the fault of blockage in each pipe. The combination of the two changes the situation of the single fault simulation of the existing technology. It can simulate more complex and diverse fault scenarios, improve the trainees' ability to deal with different faults, and increase the speed of training professional talents that meet the actual production needs.
[0015] Multiple sensors, such as speed sensors, temperature sensors, and pressure sensors, are installed on the central rotating body to collect various parameters of the central rotating body in real time. A data processing unit is equipped to analyze and process the collected data and display the data on the display screen in the form of charts, curves, etc., so that trainees can understand it intuitively and understand the changing patterns of parameters under various faults.
[0016] The solenoid valve can be opened and closed. By rotating the valve body, the flow area of the fluid is changed through the through hole, thereby simulating different degrees of pipe blockage.
