[0023] See also Figure 1 , Figure 4 The mounting mechanism 3 includes a flip frame 31. The lower end of the lubrication box 2 is hinged with two flip frames 31 symmetrically distributed front and back. A support wheel 32 is installed on the side of the flip frame 31 close to the track 1 through a bearing. The front and back sides of the lubrication box 2 are fixedly connected with guide plates 33. The guide plates 33 are slidably connected inside with connecting rods 34. The lower end of the connecting rod 34 is fixedly connected with a clamping strip 35. The side of the flip frame 31 away from the lubrication box 2 is fixedly connected with a limiting frame 36. A spring 2 37 is provided on the outer side of the connecting rod 34.

[0024] The specific implementation process of the utility model is as follows: when in use, the pipe cover 12 is flipped to open the pipe cover 12, and then refueling is carried out into the cavity formed by the partition 4 and the lubrication box 2 through the refueling pipe 11. After refueling is completed, the pipe cover 12 is flipped back to its original position.

[0025] When the lubricated track 1 needs to be replaced, the clamping strip 35 is moved, and the clamping strip 35 presses the spring 2 37. When the clamping strip 35 is separated from the limiting frame 36, the limiting of the flip frame 31 can be released, and then the flip frame 31 is flipped. After the flip frame 31 is flipped, the lubrication box 2 can be removed from the track 1, and then the track 1 can be replaced. In this way, only one lubrication box 2 needs to be used, which can effectively reduce the lubrication cost of the track 1.
