[0015] Please refer to Figures 1 to 4As shown in the figure, the present utility model proposes an intelligent lithium battery high-precision rail grinding machine, which includes a frame 9 and a rotating beam 11. The frame 9 and the rotating beam 11 play a supporting role and are used to fix other machine devices thereon. The rotating beam 11 rotates to make the grinding wheel 13 present different angles for grinding the rail at different angles. The frame 9 is fixedly connected above the rotating beam 11. On both sides above the frame 9, a remote control receiver 7 and a control box 5 are fixedly connected respectively. The control box 5 is used to control the overall device to move left and right at a fixed time and distance. The remote control receiver 7 is used to receive remote control signals to realize remote control of the whole machine to move. On the right side of the frame 9, a traveling frame 18 is assembled. The traveling frame 18 is used to fix the electrical instrument battery pack 1. Above the traveling frame 18, a first battery pack 1 is assembled. The first battery pack 1 is used to supply power to the control box, motor, etc. of the whole machine. On the outer side wall below the traveling frame 18, a traveling sensor 19 is assembled. The traveling sensor 19 is used to detect the distance of the traveling section, that is, to realize the grinding operation within two objects. Below the traveling frame 18, a traveling motor 20 is assembled. The wheel shape of the traveling motor 20 is specifically a dumbbell shape. It is fixedly connected to the fixed frame of the guide wheel assembly 10 through the damping block of the traveling frame 18. The two auxiliary support frames are connected together by a connecting frame 4 to maintain integrity and realize left and right traveling on the rail;

[0016] On one side of the frame 9, an auxiliary support frame 3 is assembled. On one side of the traveling frame 18, an auxiliary support frame 3 is also assembled. The two auxiliary support frames are fixedly connected at both ends of the connecting frame 4. Above the auxiliary support frame 3, a second battery pack 2 is assembled for standby power supply; The second battery pack 2 cooperates with the first battery pack to increase the power supply time and the operation time of the battery pack;

[0017] On both sides of the rotating beam 11, a guide wheel assembly 10 is fixedly connected. The guide wheel 10 is used to make the whole machine walk stably on the rail. On the right side of the rotating beam 11, a feed motor 12 is assembled. The feed motor 12 is used to start working by being powered by the first battery pack 1 or the second battery pack and drive the main shaft driver 15;

[0018] Specifically: on the right side of the feed motor 12, a main shaft driver 15 is arranged. On the right side of the main shaft driver 15, a first motor 16 is assembled. The main shaft driver 15 controls the first motor 16. The first motor 16 transmits torque to the main shaft through a belt. At the lower end of the main shaft, a grinding wheel 13 is assembled. Outside the grinding wheel 13, a grinding wheel cover is assembled, which is used to avoid damage to the equipment caused by sparks generated during the grinding of the grinding wheel 13 during the grinding of the grinding wheel 13, thereby blocking the splashing of sparks. Above the main shaft, a feed handwheel 14 is assembled. The feed handwheel 14 is used to manually adjust the feed amount and adjust the grinding amount of the grinding wheel 13 for grinding the rail downward;

[0019] On one side of the first motor 16, there is a second motor 17 for controlling the flipping of the rotating beam 11. When grinding the rail, for different positions of the outer profile of the rail, the flipping angle of the rotating beam 11 is required to achieve the ±90° rotation of the grinding wheel, that is, to grind both sides of the rail.

[0020] Specifically: The structure of this machine is shown in the figure and mainly consists of a power transmission part, a feeding part, a deflection control part, an auxiliary part and a grinding wheel.

[0021] 1. The power transmission part: The DC motor transmits torque to the main shaft through a coupling, a pulley and a V-belt. A grinding wheel is installed at the lower end of the main shaft to rotate the grinding wheel to achieve the purpose of grinding.

[0024] 4. The guide wheel part: It consists of side wheels, gears, guide frames, etc. When the rotating beam rotates, its guide wheels also deflect an angle to achieve the stability of grinding.

[0025] 5. The auxiliary part: It consists of a gasoline engine handrail, a connecting frame, a supporting component and a grinding wheel protection cover, etc., and is used for some safety assistance of the whole machine.

[0026] 6. The grinding wheel is used for grinding operations.

[0029] 1. It changes the traditional control method, solves the confusion of operators without grinding experience. As long as the grinding angle, depth and traveling distance are set, automatic grinding can be achieved. It saves time and effort and solves the actual problems on the grinding site.

[0030] 2. The PLC control system is used to accurately control and link the feeding, angle and traveling. The operation is simple and the labor intensity of workers is reduced to meet the high standards of current high-speed railway maintenance;

[0031] 3. The automatic traveling control system is divided into manual and single / double sensor control modes to solve different working conditions.

[0032] 4. Diversification of machine tool operation, enabling manual, wireless remote control for long-distance operation, and remote control via mobile phone or computer network, and realizing arbitrary switching among manual, semi-automatic, and fully automatic grinding functions to improve operation safety and comfort.
