[0025] (Embodiment 1)

[0026] See Figures 1 to 5, the maintenance device for the anti-collision guardrail in this embodiment includes a main frame 1 and a support frame 2. Corresponding water pipes are fixedly installed on the main frame 1, and the main frames 1 are connected by the support frame 2. A bearing plate 3 is fixedly installed at the bottom of the main frame 1, and both ends of the bearing plate 3 are penetrated by the main frame 1. A convex block 4 is fixedly installed on the top of the bearing plate 3, and a sleeve 5 is fixedly installed on the outside of the convex block 4. A ejector rod 6 is movably connected in the sleeve 5 through a spring 7, and the ejector rod 6 penetrates the sleeve 5 as a whole. One end of the ejector rod 6 that passes through the sleeve 5 and is far from the convex block 4 is fixedly connected to a first displacement plate 8, and the first displacement plate 8 is movably connected to the inside of the bearing plate 3. A first roller 9 is arranged and distributed on one side of the first displacement plate 8 close to the convex block 4. The main frame 1 has an inverted U-shaped structure, and the water pipe is located in the main frame 1. The support frame 2 provides support for the main frame 1 and serves as the skeleton of the main frame 1, so that the main frames 1 can be arranged and distributed.

[0027] When in use, the bearing plate 3 is located at the top of the concrete guardrail, and the support frame 2 is located at the top of the concrete guardrail. When the spring 7 is in a stretched state, it pushes the ejector rod 6 to move towards the end close to the convex block 4; the first displacement plate 8 moves in the groove of the bearing plate 3, and the first roller 9 on the first displacement plate 8 always keeps in contact with one side of the concrete guardrail. When there is a dislocation deviation at the joint of the concrete guardrail, due to the decrease in the stretching length of the spring 7, the first roller 9 on the first displacement plate 8 can keep in contact with one side of the concrete guardrail while not affecting the movement of the device on the concrete guardrail, thus avoiding the device from getting stuck during movement.

[0028] A clamping block 10 is arranged on the side of the first displacement plate 8 far from the convex block 4. The clamping block 10 is located at the end of the ejector rod 6 protruding from the first displacement plate 8, and the clamping block 10 is threadedly connected to the bearing plate 3 through a first screw 11. The cross-section of the clamping block 10 is L-shaped and is in a clamped state with the ejector rod 6 when the device moves on the concrete guardrail, so that the first displacement plate 8 connected to the ejector rod 6 is fixed in position in the bearing plate 3. The first screw 11 penetrates the clamping block 10 as a whole, and when rotated, the clamping block 10 moves in the bearing plate 3 while keeping parallel to the first displacement plate 8.

[0029] A limiting plate 12 is fixedly installed at the bottom of the bearing plate 3. A guide shaft 13 is arranged and distributed on one side of the first displacement plate 8 close to the limiting plate 12. One end of the guide shaft 13 protrudes from the limiting plate 12, and the guide shaft 13 is arranged in parallel with the ejector rod 6. When the first displacement plate 8 moves in the bearing plate 3, it always remains horizontal with the limiting plate 12. The guide shaft 13 can provide support for the first roller 9 on the first displacement plate 8, so that when the first roller 9 is in contact with one side of the concrete guardrail, its position is not easily deviated.

[0030] The bottom of the bearing plate 3 is provided with second rollers 14. One end of the bearing plate 3 away from the first displacement plate 8 is movably connected with a second displacement plate 15. The second displacement plate 15 is threadedly connected with the bearing plate 3 through a second screw rod 16. On the side of the second displacement plate 15 close to the first displacement plate 8, first rollers 9 are also arranged and distributed. The second rollers 14 can enable the bearing plate 3 to move on the top of the concrete guardrail. When the second screw rod 16 rotates, the second displacement plate 15 can move in the bearing plate 3 while maintaining a state parallel to the first displacement plate 8, and make the first rollers 9 on the second displacement plate 15 fit the other side of the concrete guardrail, so that the device can move on the concrete guardrail while maintaining stability.

[0031] A shunt pipe 17 is fixedly installed on the support frame 2, and the shunt pipe 17 is communicated with the water pipes in the main frame 1. One end of the shunt pipe 17 is provided with a water supply hose 18. The water supply hose 18 is connected to the shunt pipe 17 through a water pump 19. The water pump 19 is fixedly installed outside the support frame 2. The water supply hose 18 can be connected to an external water source and is powered by the water pump 19 to transport the external water source into the water pipes in the main frame 1 communicated with the shunt pipe 17, thereby avoiding the device carrying a water tank, reducing its own weight, and ensuring the stability of the device during movement.

[0032] First nozzles 20 are arranged and distributed at the bottom of the shunt pipe 17. Second nozzles 21 are provided at both ends of the water pipes in the main frame 1. Both the first nozzles 20 and the second nozzles 21 are internally communicated with the water pipes in the main frame 1. The second nozzles 21 are arranged and distributed at the bottom of the support frame 2. The first nozzles 20 and the second nozzles 21 can spray the external water source conveyed by the water pipes in the main frame 1 to the top and the bottom sides of the concrete guardrail respectively.

[0033] Reinforcing rods 22 are also provided at the bottom of the support frame 2. The reinforcing rods 22 are fixedly connected to the main frame 1. Third nozzles 23 are arranged and distributed at the bottom of the reinforcing rods 22. The third nozzles 23 are also internally communicated with the water pipes in the main frame 1. The reinforcing rods 22 connect the main frames 1 and cooperate with the support frame 2 to form the framework of the device, so as to improve the overall structural strength of the device and make the device not easily deformed. The second nozzles 21 can spray the external water source conveyed by the water pipes in the main frame 1 to the middle sides of the concrete guardrail.

[0034] During use, place the bearing plate 3 on top of the concrete guardrail and position the support frame 2 on top of the concrete guardrail; with the spring 7 in the extended state, it pushes the ejector rod 6 to move towards the end close to the bump 4; the first displacement plate 8 moves in the groove of the bearing plate 3, and the first roller 9 on the first displacement plate 8 always remains in contact with one side of the concrete guardrail. When there is a misalignment deviation at the connection of the concrete guardrail, due to the decrease in the extended length of the spring 7, the first roller 9 on the first displacement plate 8 can remain in contact with one side of the concrete guardrail while not affecting the movement of the device on the concrete guardrail, thus preventing the device from getting stuck when moving at the misaligned connection of the concrete guardrail.

[0035] Meanwhile, during normal movement, by rotating the first screw 11, the clamping block 10 connected by threads is engaged with the end of the ejector rod 6 protruding from the first displacement plate 8, so that the first displacement plate 8 parallel to the limiting plate 12 through the guide shaft 13 is fixed in position on the bearing plate 3, and in cooperation with the first roller 9 on the second displacement plate 15 threadedly connected to the second screw 16 and the second roller 14 at the bottom of the bearing plate 3, it prevents the device from loosening and tilting during normal movement on the concrete guardrail, ensuring the smooth operation of the device.

[0036] During this process, connect to an external water source through the water supply hose 18 and use the water pump 19 to provide power to transport the external water source into the water pipe in the main frame 1 that communicates with the shunt pipe 17; at the same time, spray simultaneously on the top and both sides of the concrete guardrail through the first nozzle 20, the second nozzle 21 and the third nozzle 23 that communicate with the inside of the main frame 1 to uniformly and comprehensively maintain the concrete guardrail.
