An oil dripping mechanism 96 is installed between the bottom of the oil storage box 92 and the top of the oiling brush 94. The cleaning brush 91 is installed on two rollers 6 on the same side of the guide rail 4. On the side away from the guide rail 4, the oiling brush 94 is installed on the side close to the roller 6. When the carriage 3 is moving, the cleaning brush 91 will clean the dust on the surface of the guide rail 4, and the oiling brush 94 will clean the roller 6. The roller 6 in the forward direction will push the oiling brush 94 to make the oil dripping mechanism 96 drip a small amount of lubricating oil, thereby oiling the roller 6 in the forward direction. When the roller 6 contacts the guide rail 4, the guide rail 4 is oiled, and then the roller 6 behind is oiled. No matter which direction the carriage 3 moves, it can be cleaned and oiled for maintenance, thereby avoiding aging of the guide rail 4 and the roller 6, increasing the service life and reducing the running resistance, thereby achieving the purpose of energy saving and emission reduction.

A thimble 965 is fixedly installed on the top of the oiling brush 94. The top of the thimble 965 extends to the through hole 962 at the bottom of the fixed cylinder 961. The spring 964 is a pagoda shape, and the spring 964 is in a compressed state. A refueling port with a plug is provided on the top of the oil storage box 92. The thimble 965 is a Z-shaped structure. The through hole 962 is located at the top of the bristles of the oiling brush 94. The bristles of the oiling brush 94 located at the roller 6 in front of the forward direction are subjected to the upward friction force of the roller 6. , so that the oiling brush 94 moves up slightly, and the ejector pin 965 moves up slightly to push the sealing ball 963, so that the sealing ball 963 is separated from the through hole 962, and the lubricating oil in the oil storage box 92 drips through the through hole 962 and falls along the ejector pin 965. The Z-shaped structure of the ejector pin 965 is in an upward tilted state at the turning point, so the lubricating oil will not slide along the ejector pin 965 to the brush plate of the oiling brush 94, but will only fall on the bristles, thereby oiling the roller 6, and the bristles of the oiling brush 94 at the roller 6 at the rear of the forward direction are subjected to downward friction, combined with their own gravity, so that they fit the retaining ring 95, at this time, the ejector pin 965 does not contact the sealing ball 963, and the sealing ball 963 seals the through hole 962 under the pressure of the spring 964, so that only a small amount of lubricating oil is applied when the vehicle 3 moves, so that a small amount of oil film adheres to the roller 6 and the guide rail 4 for maintenance.

[0042] Working principle: the trolley 3 is guided and moved by the roller 6 and the guide rail 4. When moving, the cleaning brush 91 is installed on the side where the two rollers 6 on the same side of the guide rail 4 are far away from each other, and the oiling brush 94 is installed on the side where the roller 6 is close to each other. When the trolley 3 is moving, the cleaning brush 91 will clean the dust on the surface of the guide rail 4, and the oiling brush 94 will clean the roller 6. The bristles of the oiling brush 94 at the roller 6 in front of the forward direction are subjected to the upward friction of the roller 6, so that the oiling brush 94 moves up slightly, and the ejector pin 965 moves up slightly to push the sealing ball 963, so that the sealing ball 963 is separated from the through hole 962, and the lubricating oil in the oil storage box 92 drips through the through hole 962 and falls along the ejector pin 965. The Z-shaped structure of the ejector pin 965 is tilted upward at the turning point. In this state, the lubricating oil will not slide along the ejector pin 965 to the brush plate of the oiling brush 94, but will only fall on the bristles, thereby oiling the roller 6, and the bristles of the oiling brush 94 at the roller 6 at the rear in the forward direction are subjected to downward friction, and combined with their own gravity, they are fitted against the retaining ring 95. At this time, the ejector pin 965 does not contact the sealing ball 963, and the sealing ball 963 seals the through hole 962 under the pressure of the spring 964, so that when the traveling vehicle 3 moves, only a small amount of lubricating oil will be applied to the roller 6, and the guide rail 4 will be oiled when the roller 6 contacts the guide rail 4, and then the roller 6 at the back will be oiled. No matter which direction the traveling vehicle 3 moves, it can be cleaned and oiled for maintenance, thereby avoiding aging of the guide rail 4 and the roller 6, increasing their service life and reducing walking resistance, thereby achieving the purpose of energy saving and emission reduction.
