DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 A road surface maintenance device for highway construction includes a vehicle body 1, a water tank 8 and a support block 2 are fixedly connected to the vehicle body 1, two support rods 4 are rotatably connected to the support block 2, each support rod 4 is fixedly connected to a shunt pipe 5, each shunt pipe 5 is fixedly connected to a plurality of booster nozzles 17, the water tank 8 is connected to two water pumps through two drainage pipes, each water pump is connected to the corresponding shunt pipe 5 through a bellows 6, an asphalt storage barrel 13 is fixedly connected to the vehicle body 1, a discharge pipe 23 is fixedly connected to the bottom of the asphalt storage barrel 13, a solenoid valve is arranged on the discharge pipe 23, an installation groove is opened on the vehicle body 1, a first motor is arranged on the inner wall of one side of the installation groove, a driving end of the first motor is fixedly connected to a rotating shaft 24, and a rotating rod 26 is rotatably connected to the inner wall of one side of the installation groove.

[0028] The rotating shaft 24 and the rotating rod 26 are both fixedly connected with a rotating block 25, the cross section of which is in a concave shape. Each rotating block 25 is provided with a rotating assembly, which includes a bracket 14 arranged on the rotating block 25, the cross section of which is in an I-shape, and two grooves for connecting the bracket 14 are provided on the rotating block 25, and a flattening roller 15 is rotatably connected to the bracket 14.

[0029] The rotating shaft 24 is fixedly connected with a first pulley 29, and the rotating rod 26 is fixedly connected with a second pulley 31. The first pulley 29 is connected to the second pulley 31 through a conveyor belt 30. The first motor drives the rotating shaft 24 to rotate a certain angle, and the first pulley 29 rotates at the same time. Under the transmission action of the conveyor belt 30, the second pulley 31 and the rotating rod 26 rotate at the same time.

[0030] Each bracket 14 is connected to the corresponding rotating block 25 through a plurality of first bolts 28. Each rotating block 25 is provided with a plurality of circular grooves for connecting the first bolts 28. After the flattening roller 15 has been used for a long time, each first bolt 28 is rotated, and the first bolts 28 and the circular grooves are threadedly connected, so that one end of the first bolt 28 is disengaged from the corresponding circular groove on the rotating block 25. Then, the bracket 14 can be taken out to facilitate cleaning of the flattening roller 15 on the bracket 14, or replacement of the bracket 14 and the flattening roller 15.

[0031] A second motor is installed on the support block 2, and a driving end of the second motor is fixedly connected to a fixed rod 16, and a first gear 18 is fixedly connected to the fixed rod 16. Each support rod 4 is fixedly connected to a second gear 3, and the second gear 3 and the first gear 18 are meshingly connected. Under the driving action of the second motor, the fixed rod 16 and the first gear 18 rotate, and under the transmission action of the two second gears 3, the two support rods 4 and the shunt pipe 5 rotate at the same time, so as to facilitate the storage of the shunt pipe 5 directly above the vehicle body 1 to prevent the shunt pipe 5 from affecting the driving of other vehicles.

[0032] A water inlet pipe is fixedly connected to the water tank 8, and a pipe cover 7 is threadedly connected to the water inlet pipe. When the pipe cover 7 is rotated and the pipe cover 7 and the water inlet pipe are threadedly connected, they will be separated from the water inlet pipe, so that the pipe mouth of the water inlet pipe is exposed to the outside, so that clean water can be added to the water tank 8 through the water inlet pipe.

[0033] Two fixed plates 10 are fixedly connected to the vehicle body 1, and the two fixed plates 10 are symmetrically arranged. A reciprocating screw 19 is rotatably connected between the two fixed plates 10, and a moving block 9 is threadedly connected to the reciprocating screw 19. A third motor is fixedly connected to one of the fixed plates 10, and a driving end of the third motor is fixedly connected to one end of the reciprocating screw 19. A telescopic rod 21 is fixedly connected to the moving block 9, and an end of the telescopic rod 21 away from the moving block 9 is fixedly connected to the corresponding fixed plate 10.

[0034] An electric push rod 22 is installed on the moving block 9, and the driving end of the electric push rod 22 is fixedly connected to the mounting rod 20, and the lower end of the mounting rod 20 is fixedly connected to the electromagnet 27. An opening for the electromagnet 27 to move up and down is opened on the vehicle body 1. A collection frame 11 is provided on the vehicle body 1, and an ear plate is fixedly connected to the surface of one side of the collection frame 11. The ear plate is connected to the vehicle body 1 through a second bolt 12, and a slot for connecting the second bolt 12 is opened on the vehicle body 1.

[0035] Driven by the third motor, the reciprocating screw 19 and the fixed plate 10 rotate relative to each other, and the moving block 9 moves along the reciprocating screw 19 at the same time, and the telescopic rod 21 is telescopically deformed at the same time. The telescopic rod 21 can limit the moving trajectory of the moving block 9 to prevent the moving block 9 from swinging. When the electromagnet 27 moves to the top of the collecting frame 11 together with the moving block 9, the electromagnet 27 is no longer energized. The iron filings and metal impurities adsorbed on the electromagnet 27 will fall into the collecting frame 11 under the action of gravity and be collected. The second bolt 12 is rotated to make it threadedly connected to the slot until the second bolt 12 is disengaged from the slot. After that, the collecting frame 11 can be removed from the vehicle body 1 to facilitate the rapid processing of the iron filings and metal impurities in the collecting frame 11.

[0036] In the present invention, when in use, under the action of two water pumps, the water flow inside the water tank 8 can be transported to the two shunt pipes 5 through the bellows 6, and the water flow inside the shunt pipes 5 is sprayed onto the road surface through multiple booster nozzles 17, so as to perform water sprinkling maintenance on the road surface. When the vehicle body 1 moves to the pothole, the solenoid valve on the discharge pipe 23 opens, and the asphalt in the asphalt storage barrel 13 falls into the pothole through the discharge pipe 23. Then, the first motor drives the rotating shaft 24 to rotate a certain angle, and the first pulley 29 rotates at the same time. Under the transmission action of the conveyor belt 30, the second pulley 31 and the rotating rod 26 rotate at the same time. After the two rotating blocks 25 rotate together with the rotating shaft 24 and the rotating rod 26 respectively, the flattening roller 15 will contact the ground. Then, as the vehicle body 1 moves, the flattening roller 15 can flatten the asphalt in the pothole to achieve the repair of the pothole.

[0037] In the process of multiple booster nozzles 17 spraying water onto the road surface for road surface watering maintenance, the flattening roller 15 can simultaneously flatten the asphalt in the potholes to repair the potholes. Therefore, while the road surface is being watered and maintained, temporary road surface repair and maintenance can also be achieved. There is no need to use road surface maintenance devices of other specifications to assist in the completion. The operation is relatively simple and quick, the road surface maintenance device has more functions, the road surface maintenance efficiency is higher, and it is beneficial to the maintenance of the road surface.

[0038] Under the driving action of the electric push rod 22, the electromagnet 27 at the lower end of the mounting rod 20 passes through the opening on the vehicle body 1, and the electromagnet 27 stops moving down after it is at a certain distance from the ground. The electromagnet 27 is energized, and as the vehicle body 1 moves, iron filings and some metal impurities on the road surface will be adsorbed on the electromagnet 27 under the action of magnetic adsorption, thereby preventing the tire of the vehicle body 1 from being pressed on the iron filings and causing a tire blowout during driving, which is beneficial to the normal movement of the vehicle body 1 and facilitates the normal maintenance of the road surface.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
