Each of the special-shaped grooves 13 is provided with a first sliding rod 8 and a second sliding rod 14 in the direction of moving away from each other horizontally. The end of the first sliding rod 8 away from the rotating disc 7 is arranged to slide in the horizontal direction through the first guiding assembly. Each of the two first sliding rods 8 is rotatably arranged with a group of watering assemblies on the side away from the first guiding assembly. The end of the second sliding rod 14 away from the rotating disc 7 is arranged to swing through the second guiding assembly. Each of the two second sliding rods 14 is arranged with a group of cleaning assemblies on the side away from the second guiding assembly. During the rotating process of the special-shaped groove 13, the special-shaped groove 13 drives the second sliding rod 14 and the first sliding rod 8 to move reciprocally. When the special-shaped groove 13 drives the second sliding rod 14 to move towards the rotating disc 7, the second sliding rod 14 pulls the cleaning assembly to move together to clean. When the special-shaped groove 13 drives the first sliding rod 8 to move towards the rotating disc 7, the first sliding rod 8 pulls the watering assembly to move together to water.

[0031] The first guiding assembly comprises a first connecting block 9. The first connecting block 9 is arranged on the support 5. The two sides of the first connecting block 9 are provided with sliding grooves for the movement of the first sliding rod 8. The sliding groove of the first connecting block 9 is provided with a first reset spring 10. One end of the first reset spring 10 is connected with the inner wall of the sliding groove of the first connecting block 9 on the side close to the rotating disc 7. The other end of the first reset spring 10 is connected with the end of the first sliding rod 8 away from the rotating disc 7.

[0032] The second guiding assembly comprises a horizontal moving unit and a rotating unit. The horizontal moving unit comprises a second connecting block 15 and a sliding square block 23. The second connecting block 15 is arranged on the support 5. The two sides of the second connecting block 15 are provided with sliding grooves for the sliding of the sliding square block 23. The sliding groove of the second connecting block 15 is provided with a second reset spring 24. One end of the second reset spring 24 is connected with the inner wall of the sliding groove of the second connecting block 15 on the side close to the rotating disc 7. The other end of the second reset spring 24 is connected with the end of the sliding square block 23 close to the rotating disc 7. The sliding square block 23 is connected with the rotating unit through a rotating shaft 18. The rotating unit comprises a special-shaped gear 17 and a special-shaped rack 16 which are engaged with each other. The special-shaped gear 17 comprises an engaging tooth surface and a smooth surface. The special-shaped rack 16 comprises engaging teeth which are arranged at intervals. The engaging teeth of the special-shaped rack 16 are adapted to the engaging tooth surface of the special-shaped gear 17. The special-shaped gear 17 is arranged on the rotating shaft 18. The special-shaped rack 16 is arranged on the top wall outside of the sliding groove of the second connecting block 15. The end of the rotating shaft 18 away from the sliding square block 23 is arranged with the cleaning assembly.

[0033] The cleaning assembly comprises a cleaning rod 19, a cleaning frame 20 and a cleaning brush 21. The cleaning rod 19 is arranged at one end of the second sliding rod 14 away from the rotating disc 7 and is located at the side where the two second sliding rods 14 are away from each other. The cleaning rod 19 is arranged perpendicular to the length direction of the T-shaped beam body 1. The cleaning frame 20 is arranged at the lower end of the cleaning rod 19. The cleaning brush 21 is detachably arranged at the lower end of the cleaning frame 20. During the rotation of the special-shaped groove 13, when the special-shaped groove 13 drives the second sliding rod 14 to move towards the rotating disc 7, the second sliding rod 14 drives the cleaning rod 19 to move. The cleaning rod 19 drives the sliding block 23 to slide on the second connecting block 15 towards the rotating disc 7. During this process, the special-shaped gear 17 meshes with the special-shaped rack 16. The special-shaped gear 17 rotates a half turn under the action of the special-shaped rack 16. The special-shaped gear 17 drives the rotating shaft 18 and the cleaning rod 19 to rotate a half turn. The cleaning rod 19 drives the cleaning frame 20 and the cleaning brush 21 to tilt at a certain angle. Then, after the special-shaped gear 17 and the special-shaped rack 16 disengage, under the action of gravity, the cleaning rod 19 and the cleaning frame 20 are displaced to the vertical state. In this way, the cleaning rod 19 and the cleaning frame 20 are displaced from the tilting angle to the vertical state, which simulates the cleaning state and realizes continuous cleaning of the road surface, so as to ensure that the garbage on the T-shaped beam body 1 is cleaned away and the T-shaped beam body 1 is pretreated to ensure that there is no other debris on the T-shaped beam body 1. This avoids the situation that the debris on the T-shaped beam body 1 absorbs the water sprayed by the watering assembly during the watering process of the watering assembly on the support 5, which causes the T-shaped beam body 1 to be unable to absorb water and leads to dry cracking. This further ensures the maintenance quality and efficiency of the T-shaped beam body 1 and improves the quality of the T-shaped beam body 1.

The spraying rod 11 is arranged at one end of the first sliding rod 8 away from the rotating disc 7 by a torsional spring and is located at the side where the two first sliding rods 8 are away from each other. When working, when the spraying rod 11 is scraped with garbage and other debris, the spraying rod 11 will tilt towards the side close to the rotating disc 7, which can ensure that the debris is blown away by the wind and will not hang on the spraying rod 11 all the time, avoiding affecting the effect of the spraying rod 11 on spraying water on the T-shaped beam body 1. The use of a torsional spring can help the spraying rod 11 to reset when there is no obstruction. The spraying rod 11 is arranged perpendicular to the length direction of the T-shaped beam body 1. A plurality of nozzles 12 for spraying water are uniformly arranged at the lower end of the spraying rod 11. When working, as Figure 6As shown, during the rotation of the rotating disc 7, when the recess of the special-shaped groove 13 on the rotating disc 7 rotates to contact the first sliding rod 8, the first sliding rod 8 is pulled towards the rotating disc 7, at this time, the spraying rod 11 moves towards the rotating disc 7 under the movement of the first sliding rod 8, and the spraying rod 11 also moves towards the rotating disc 7 synchronously, thereby spraying water on the T-shaped beam body 1, then under the continuous rotation of the rotating disc 7, when the first sliding rod 8 gradually separates from the recess of the special-shaped groove 13, the first sliding rod 8 gradually moves away from the rotating disc 7 when moving to the protrusion of the special-shaped groove 13, and the special-shaped groove 13 is used to realize the reciprocating movement of the spraying rod 11, and when the support 5 moves linearly, the unit area of the T-shaped beam body 1 can be repeatedly sprayed, thereby ensuring that the T-shaped beam body 1 can be fully irrigated by water, so as to achieve the purpose of maintaining the T-shaped beam body 1, and avoid the problem that in the traditional spraying, the unit area of the T-shaped beam body 1 is only sprayed once, which may cause insufficient water and incomplete irrigation of the T-shaped beam body 1, thereby causing the T-shaped beam body 1 to crack due to lack of water during construction, thereby affecting the construction quality of the T-shaped beam body 1 and causing unnecessary losses. The present application does not need the staff to hold a water pipe to spray water on the T-shaped beam body 1 back and forth on the road surface, and during the spraying process, the uneven spraying of the staff is avoided, the construction quality of the large cantilever prestressed cap beam is ensured, the outdoor work intensity of the staff is reduced, the discomfort of the staff caused by high temperature during outdoor work is avoided, and the health of the outdoor workers is improved.

[0036] The moving assembly further comprises support frames 25 arranged on both sides of the first motor 27, and the support frames 25 are rotatably arranged with rollers at the ends away from the support frame 5; in operation, the support frames 25 and the support frame 5 form a triangle, and the stability of the triangle can ensure that the support frame 5 will not fall down when encountering extreme weather, such as a strong wind.

[0037] Working principle: in operation, the first motor 27 drives the gear 4 to rotate, and the gear 4 drives the support frame 5 to move linearly under the action of the main rack 2; at the same time, the second motor 22 is started to drive the rotating disc 7 to rotate, and the rotating disc 7 drives the watering assembly and the cleaning assembly to move alternately in the rotating process; first, the cleaning assembly cleans the T-shaped beam body 1, and then the watering assembly reciprocatingly waters the T-shaped beam body 1; as shown in the whole device, the cleaning can be performed first, and then the watering assembly waters, which ensures the removal of sundries on the T-shaped beam body 1 and avoids the accumulation of too many sundries on the T-shaped beam body 1; the water sprayed by the watering assembly on the T-shaped beam body 1 is absorbed by the sundries, and cannot achieve the purpose of maintaining the T-shaped beam body 1.
