[0022] See Figures 1-4As shown, this utility model embodiment provides a tamping machine with vehicle-to-ground inter-control function, including a frame 1, a connecting device 2 at the bottom of the frame 1, and a satellite trolley 3 mounted on the connecting device 2; specifically, the connecting device 2 is located at the bottom front end of the frame 1. From front to back, the frame 1 is provided with a front driver's cab 11, a rear driver's cab 13, and a working mechanism. The working mechanism includes a track lifting and shifting device 14 and a tamping device 15. The front driver's cab 11 is equipped with a main vehicle computer 12. In the rear driver's cab, the operator can control the operation of the tamping device and observe the working status of the track lifting and shifting device and the tamping device. The key is to observe whether the clamps of the track lifting and shifting device are derailed at the track clamp. When the tamping device is operating on a curve, its lateral movement cylinder should be adjusted in time to prevent the tamping device from hitting the rail when it is lowered into the track bed. The track lifting and shifting device is used to receive instructions from the main computer, and its clamps clamp the rail to adjust the versine, elevation, and superelevation. The tamping device receives instructions from the main computer, inserts itself into the track bed and clamps the ballast at both ends of the sleepers, making the track bed more compact.

[0023] See Figures 5-7 As shown, the connecting device 2 includes a transverse telescopic rod 23, two vertical telescopic rods 21, and two support arms 25. The two vertical telescopic rods 21 are arranged opposite each other, and their upper ends are respectively connected to the frame 1, while their lower ends are respectively connected to both ends of the transverse telescopic rod 23. The two support arms 25 are arranged opposite each other, and their proximal ends are respectively connected to both ends of the transverse telescopic rod 23, while their distal ends are respectively connected to the frame 1 via detachable chains 26. Specifically, the connecting device 2 also includes two lifting cylinders 22. The cylinder body of the lifting cylinder 22 is connected to the frame 1. The vertical telescopic rod 21 includes a vertical sliding sleeve and a vertical sliding shaft. The vertical sliding sleeve is connected to the frame 1, and the vertical sliding shaft is connected to the piston rod of the corresponding lifting cylinder 22. The connecting device 2 also includes a transverse hydraulic cylinder 24. The transverse telescopic rod 23 includes a transverse sliding sleeve and a transverse sliding shaft. The cylinder body of the transverse hydraulic cylinder 24 is connected to the transverse sliding sleeve, and the piston rod of the transverse hydraulic cylinder 24 is connected to the transverse sliding shaft. The distal ends of the two support arms 25 converge inward to form a contraction section 27. The sliding shaft and the sliding sleeve are fitted with a clearance, and the sliding shaft moves within the sliding sleeve. Specifically, the vertical sliding shaft of the vertical telescopic rod 21 is connected to the transverse sliding sleeve of the transverse telescopic rod 23.

[0024] See Figures 8-10As shown, the satellite trolley 3 includes a body 31 and detection wheels 36. The bottom of the body 31 is equipped with active running wheels 32 and passive running wheels 33. A drive motor 34 is mounted on the body 31 and connected to the active running wheels 32 via a sprocket and chain 35. The detection wheels 36 are located at the bottom of the body 31, between the active and passive running wheels 32 and 33. Specifically, the body 31 is equipped with a battery 37 and an audible and visual alarm 38. The audible and visual alarm 38 includes a warning light and a sound alarm, located on the top of the trolley, used to alert nearby construction personnel. The battery 37 is a lead-acid battery, designed with a charging interface and a power detection device. The satellite trolley also includes a data processing center, including a data acquisition unit, a data processing unit, and a data output unit; and a communication module, including a processor, memory, radio frequency unit, and antenna, which modulates the data transmitted from the data processing center into electromagnetic signals and sends them to the electrical system of the tamping machine, and receives instructions from the tamping machine.

[0025] The working principle of this utility model is as follows: See Figure 11 As shown, the satellite trolley is fixed to the bottom of the main vehicle when not in operation. When the tamping machine arrives at the work site, the operator in the front cab unlocks the satellite trolley on the main vehicle and controls its movement. The satellite trolley detects the versine, elevation, and superelevation of the track it passes over, transmitting the detected data to the main computer in the front cab of the main vehicle. The computer on the tamping machine receives and analyzes the data, issuing instructions to the working mechanism, including the tamping device and the track lifting and shifting device. The operator in the rear cab controls the insertion of the tamping device and the clamping state of the track lifting and shifting device, thereby correcting the track to meet the standard requirements. During operation, the satellite trolley runs ahead, detecting data, and the main vehicle corrects the track based on the detected data. After the operation is completed, the tamping machine retracts the satellite trolley, the operator locks it, and the vehicle drives out of the track closure point.

[0026] This utility model achieves high efficiency, precision and automation of tamping operations through intelligent satellite trolley design and vehicle-to-ground interconnection technology, effectively improving the quality and efficiency of track maintenance work.
