[0036] Two fastener identification sensors 42 are respectively arranged on the left and right ends of the sliding frame 1 and connected to the controller. The fastener identification sensor 42 is a metal sensor or an ultrasonic sensor. When the metal sensor approaches the boundary of the fastener 61, the switch principle is executed. Because only one side of the fastener 61 is stuck at the bottom of the rail, and the opposite side or the lower sleeper is made of concrete material, only the fastener metal is sensed, and the sensing distance and sensitivity can be adjusted; the ultrasonic sensor is set to detect the sensing distance from the bottom to the top of the fastener 61. Because the fastener 61 protrudes above the bottom end on other planes, the mechanical waves emitted by the ultrasonic sensor have the characteristics of small diffraction and good directionality, that is, they can become rays and propagate in a direction, so only the fastener 61 is sensed. The fastener recognition sensor 42 at the left end of the sliding frame 1 and the inverted "U" shaped nozzle 23 at the left end are distributed front and back. The fastener recognition sensor 42 at the left end of the sliding frame 1 is opposite to the inverted "U" shaped nozzle 23 at the right end of the sliding frame 1.

[0038] Depending on the size of the engineering task, the power supply can be replaced with batteries or generators.

[0039] Preferably, the sliding frame 1 is provided with a servo 11 for driving the inverted "U"-shaped nozzle 23 to swing back and forth and connected to the controller. The servo 11 is installed on the sliding frame 1, and the inverted "U"-shaped frame 231 is installed on the swing plate of the servo 11.

During the entire injection process, the electric valve is in an open state. The angle adjustment button is clicked to control the steering engine 11 to align the inverted "U"-shaped nozzle 23 with the track fastener 61, and the start button is clicked. The motor 13 drives the roller 12 of the sliding frame 1 to move along the track. The remote control device 7 can also send a walking or stopping command to the wireless signal receiving module in the control panel 41.

[0042] When the fastener identification sensor 42 at the left end of the sliding frame 1 moves out of the fastener area of ​​the left leg, the fastener identification sensor 42 at the left end stops sending electrical signals to the controller, and the controller controls the electromagnetic valve 34 of the second air pipe 33 to close, and the nozzle 233 stops siphoning and spraying oil;

[0043] When the fastener identification sensor 42 at the right end of the sliding frame 1 enters the fastener area of ​​the right rail, the fastener identification sensor 42 at the right end senses the fastener 61 and sends an electrical signal to the controller, and the controller controls the solenoid valve 34 of the first air pipe 32 to open, and the nozzle 233 at the left end of the sliding frame 1 sprays oil toward the fasteners 61 on both sides of the left rail.

[0044] When the fastener identification sensor 42 at the right end of the sliding frame 1 moves out of the fastener area of ​​the right leg, the fastener identification sensor 42 at the right end stops sending an electrical signal to the controller, and the controller controls the electromagnetic valve 34 of the first air pipe 32 to close and stop spraying oil. Thereafter, the above operation automatically cycles until the task of spraying oil for the fasteners within the preset range is completed, and the button of the electric valve 24 controlling the left and right end oil pipes 22 of the sliding frame 1 is closed, so that the electric valve 24 cuts off the connection between the oil tank 21 and the nozzle 233. When the liquid level sensor in the oil tank 21 senses that the liquid level drops to the preset alarm position, the liquid level sensor sends an electrical signal to the controller, and the controller controls the electric valve 24, the electromagnetic valve 34, and the motor 13 to close, and controls the sound prompter to emit an oil tank oil shortage alarm prompt sound.

The controller controls the motor 13 to drive the sliding frame 1 to move according to the preset stroke and speed. At the same time, the controller controls the solenoid valve 34 on the first air pipe 32 to be in an open state so that the gas in the first air pipe 32 is sprayed through the bronchial pipe 321 and the lubricating grease gun 25.
