[0031] Embodiment 2:

[0032] On the basis of Example 1, in order to make several groups of cleaning elastic blocks 26 or maintenance cotton blocks 4 contact with the outside of the connecting screw 20 after several groups of arc plates 1 are assembled together, the connecting box 3 is slidably connected in the connecting cavity 32, and the connecting cavity 32 is opened in the arc plate 1. The two sides of the connecting box 3 are fixedly connected to the limiting rod 23, and the limiting rod 23 is slidably connected in the limiting groove 25. The limiting groove 25 is opened in the connecting cavity 32. A connecting spring 22 is fixedly connected in the limiting groove 25, and the other end of the connecting spring 22 is fixedly connected to the limiting rod 23. When the connecting screw 2 0 is larger, so that when several groups of arc plates 1 are not assembled together, several groups of cleaning elastic blocks 26 or maintenance cotton blocks 4 have already contacted the outer side of the connecting screw 20. At this time, as the arc plates 1 continue to move, the connecting box 3 will move into the connecting cavity 32. During the movement, the connecting box 3 will drive the limiting rod 23 to move along the limiting groove 25, so that the connecting spring 22 located in the limiting groove 25 is compressed. Under the elastic force of the connecting spring 22, the cleaning elastic block 26 or the maintenance cotton block 4 will always be in contact with the outer side of the connecting screw 20;

[0033] The transmission mechanism includes two groups of transmission gears 2, both of which are meshed with the inner side of the crawler 24, and the upper and lower ends of the transmission gears 2 are movably connected to the inner side of the connection box 3. The upper end of one group of transmission gears 2 is fixedly connected to the output end of the transmission motor 27, and the transmission motor 27 is fixedly installed in the connection box 3. By turning on the transmission motor 27, the transmission gear 2 connected to its output end starts to rotate, and the rotation of the transmission gear 2 drives the crawler 24 to start moving. The movement of the crawler 24 drives the cleaning elastic block 26 to move, so that the cleaning elastic block 26 contacts the outer side of the connecting screw 20. After the positions of several groups of cleaning elastic blocks 26 are adjusted, the transmission motor 27 is controlled to be self-locking;

[0034] The connecting mechanism includes a cross-shaped connecting tube 31, which is slidably connected to the sliding cavity 30, and the sliding cavity 30 is opened in the connecting box 3, one end of the cross-shaped connecting tube 31 is clamped in the guide cavity 28, and the other end is fixedly connected to the telescopic plastic hose 6, the clamping end of the cross-shaped connecting tube 31 is arranged in an arc shape, and a first spring 29 is sleeved on the outer side of the cross-shaped connecting tube 31, one end of the first spring 29 is fixedly connected to the cross-shaped connecting tube 31, and the other end is fixedly connected to the sliding cavity 30. Since the clamping end of the cross-shaped connecting tube 31 is arranged in an arc shape, the cross-shaped connecting tube 31 will be separated from the guide cavity 28 during the process of the crawler 24 driving the cleaning elastic block 26 and the maintenance cotton block 4 to move, and when the guide cavity 28 opened in the crawler 24 moves to the position of the cross-shaped connecting tube 31 again, at this time, under the elastic force of the first spring 29, the cross-shaped connecting tube 31 will be clamped into the guide cavity 28 again;

[0035] The lifting mechanism includes a screw rod 12, which is screwed into the lifting plate 19, the lower end of the screw rod 12 is movably connected to the support box 14, and the upper end is fixedly connected to the output end of the first motor 13. The first motor 13 is fixedly installed in the support box 14. When the first motor 13 is turned on, the screw rod 12 connected to its output end starts to rotate, and the lifting plate 19 is driven to move upward through the rotation of the screw rod 12. The movement of the lifting plate 19 causes several groups of arc-shaped plates 1 to move downward synchronously. A second motor 18 is fixedly connected to the mounting plate 17, and the output end of the second motor 18 is fixedly connected to the upper end of the support box 14. Several groups of mounting screws 16 are provided in the mounting plate 17. An electric telescopic cylinder 10 is fixedly connected to one end of the make-shift groove 7, and the output end of the electric telescopic cylinder 10 extends into the make-shift groove 7. The arc plate 1 is in the groove 7 and is fixedly connected with the T-shaped connecting rod 5. A push switch 21 is installed on the upper end of the arc plate 1. The push switch 21 can select a suitable size and model in actual use. The liquid storage mechanism includes an annular storage box 11, and the annular storage box 11 is fixedly sleeved on the outside of the support box 14. A micro pump 15 is fixedly installed on the lower end of the annular storage box 11. The micro pump 15 can select a suitable size and model in actual use. The input end of the micro pump 15 extends into the annular storage box 11, and the output end extends into the annular connecting pipe 8. The micro pump 15 is started to transport the maintenance oil in the annular storage box 11 to the annular connecting pipe 8. The maintenance oil entering the annular connecting pipe 8 enters the guide cavity 28 through the telescopic plastic hose 6, and is finally absorbed by the maintenance cotton block 4.

[0036] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a track maintenance vehicle, including the above-mentioned connecting parts maintenance device.

[0037] Working principle: when in use, the mounting plate 17 is mounted together with the track maintenance vehicle mounting vehicle through several groups of mounting screws 16. When the connecting screw 20 is displaced upward, the first motor 13 is turned on to drive the screw 12 connected to its output end to start rotating, and the lifting plate 19 is driven to move upward by the rotation of the screw 12. The movement of the lifting plate 19 causes several groups of arc plates 1 to move downward synchronously, so that the connecting screw 20 is arranged between the several groups of arc plates 1. When the arc plates 1 cannot move, the first motor 13 is turned off and several groups of electric telescopic cylinders 10 are turned on. After the electric telescopic cylinder 10 is started, it drives the T-shaped connecting rod 5 connected to its output end to move inward. The inward movement of several groups of T-shaped connecting rods 5 drives the arc plates 1 connected thereto to move, so that several groups of arc plates 1 clamp the connecting screw 20.

[0038] By turning on the transmission motor 27, the transmission gear 2 connected to its output end starts to rotate, and the rotation of the transmission gear 2 drives the crawler 24 to start moving. The movement of the crawler 24 drives the cleaning elastic block 26 to move, so that the cleaning elastic block 26 contacts the outer side of the connecting screw 20. After the positions of several groups of cleaning elastic blocks 26 are adjusted, the transmission motor 27 is controlled to self-lock, and the second motor 18 is turned on. Since the mounting plate 17 is installed together with the track maintenance vehicle, the second motor 18 will drive the support box 14 connected to its output end to start rotating after it is started. The rotation of the support box 14 causes several groups of arc plates 1 to start rotating along the outer side of the connecting screw 20. By turning on the first motor 13, the lifting plate 19 is driven to move slowly upward, so that several groups of cleaning elastic blocks 26 rotate along the outer side of the connecting screw 20 and move slowly upward at the same time, thereby completing the cleaning of the outer surface of the connecting screw 20.

[0039] When the push switch 21 at the upper end of the arc plate 1 contacts the connecting screw 20, the push switch 21 is pressed, so that the transmission motor 27 starts to rotate the cleaning elastic block 26 into the connecting box 3, and the track 24 rotates the maintenance cotton block 4 to contact the outside of the connecting screw 20. After the rotation is completed, the transmission motor 27 is in a self-locking state, and the cross-shaped connecting pipe 31 is clamped into the guide cavity 28 under the elastic force of the first spring 29. At this time, the micro pump 15 starts to transport the maintenance oil in the annular storage box 11 to the annular connecting pipe 8. The maintenance oil entering the annular connecting pipe 8 enters the guide cavity 28 through the telescopic plastic hose 6, and is finally absorbed by the maintenance cotton block 4. At this time, several groups of maintenance cotton blocks 4 rotate along the outside of the connecting screw 20 and slowly move downward, so that the maintenance oil can be evenly applied to the outside of the connecting screw 20. After the application is completed, the electric telescopic cylinder 10 can be used to control the opening of several groups of arc plates 1.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
