Description

Technical Field

[0001] The invention relates to the technical field of foundation maintenance, and in particular to a foundation maintenance device for road and bridge engineering management. Background Art

[0002] Road and bridge engineering originally refers to the survey, design, construction, maintenance, and management of roads and bridges. The foundation refers to the building The soil or rock supporting the foundation below, the soil layer serving as the building foundation is divided into rock, gravel soil, sand, silt, clay and artificial fill. There are two types of foundations: natural foundation and artificial foundation (composite foundation). After the construction of the road foundation is completed, it needs to be maintained manually to ensure that the quality of the foundation can meet the national requirements. In the process of maintaining the road and bridge foundation, it is necessary to sprinkle water on the foundation for maintenance.

[0003] The existing device uses a nozzle to spray water evenly on the foundation surface. However, due to the large amount of dust on the foundation surface, the dust easily blocks the spray hole at the bottom of the nozzle during the long-term spraying process of the maintenance device, making the spray water not sprayed evenly, resulting in poor roadbed maintenance effect in the blind area of ​​spraying, reducing the foundation maintenance quality, and requiring the operator to stop the operation of the maintenance device and clean or replace the nozzle. The operation is complicated, the work efficiency is low, and the foundation maintenance effect is affected. To this end, we propose a foundation maintenance device for road and bridge engineering management.

[0023] The specific implementation of this embodiment is as follows: when the nozzle 2107 needs to be replaced, the external controller controls the three-way solenoid valve 2202 to start, so that the water pump 2201 draws outside air into the inner cavity of the first water outlet pipe 2204 through the three-way solenoid valve 2202, and the air will push the first water outlet pipe 2204, the first telescopic tube 2205, the second water outlet pipe 2206, the second telescopic tube 2207, the third water outlet pipe 2208, the piston cylinder 2209, the four water outlet pipes, the cavity 2109, the diverter pipe 2110, the third telescopic tube 2111 and the connecting pipe 2112 to discharge the inner cavity liquid, and then the external controller turns off the water pump 2201. At this time, there is no water pressure in the piston cylinder 2209. Under the joint action of multiple second springs 2216, the I-shaped plate 2213 moves outward. The first conveyor roller 2104 is driven by the external controller 2103 to rotate, and the second conveyor roller 2104 and the second conveyor roller 2105 cooperate with each other to drive the conveyor belt 2106 to move, so that the upper and lower groups of the nozzles 2107 are exchanged. After the exchange is completed, the upper and lower groups of the nozzles 2107 are exchanged. The external controller controls the water pump 2201 and the three-way solenoid valve 2202 to start. Under the action of the water pump 2201, the water in the inner cavity of the water storage tank 12 enters the inner cavity of the first water outlet pipe 2204 through the water inlet pipe 2203, and flows into the inner cavity of the piston cylinder 2209 through the first telescopic tube 2205, the second water outlet pipe 2206, the second telescopic tube 2207 and the third water outlet pipe 2208.

The piston plate 2210 drives the I-plate 2213 to move through the piston rod 2212. The I-plate 2213 drives the constraint rod 2214 to move, so that it is engaged with the corresponding drive sleeve, so as to limit the upper and lower groups of nozzles 2107. The water flows through the fourth water outlet pipe 2211 and When the water in the cavity 2109 flows into the inner cavity of the shunt pipe 2110, the water pressure drives the pressure plate 2114 to move downward, so that the connecting pipe 2112 moves downward, and the connecting pipe 2112 is connected with the nozzle 2107. When the connecting pipe 2112 moves to the bottom, the L-shaped block 2215 contacts the trapezoidal block 2119, and the corresponding first spring 2118 is compressed by the trapezoidal block 2119, so that the trapezoidal block 2119 moves inward. When the L-shaped block 2215 is separated from the trapezoidal block 2119, the trapezoidal block 2119 is reset under the action of the first spring 2118, and the cooperation with the L-shaped block 2215 can realize the function of limiting the connecting pipe 2112.

The whole process takes less time, so the purpose of rapid and automatic replacement of the nozzle 2107 can be achieved, and the nozzle 2107 can be replaced frequently to ensure that the nozzle 2107 will not be blocked during use, so that there will be no blind area for spraying during operation, thereby improving the quality of foundation maintenance.

[0026] The specific implementation of this embodiment is as follows: when water flows in the inner cavity of the second water outlet pipe 2206, the water flows through the guide ring and the impeller inside the impeller sleeve 2301 to drive the drive shaft to rotate, and the drive shaft drives the buffer box 2302 to rotate, and the buffer box 2302 drives the cleaning brush 2305 to rotate through the baffle 2304. At this time, the electric push rod 2306 is controlled by the external controller to start, and the electric push rod 2306 performs a slow feeding movement. The electric push rod 2306 drives the second water outlet pipe 2206 to move downward, so that the cleaning brush 2305 contacts the surface of the nozzle 2107. By compressing the corresponding third spring 2303, a certain buffer margin can be given to the cleaning brush 2305 to ensure its cleaning effect. The dust and impurities generated by the cleaning fall on the conveyor belt 2106 and the guide block 2 The surface of 309, when the conveyor belt 2106 moves, the two cleaning plates 2307 arranged in an "eight" shape guide the dust falling on the surface of the conveyor belt 2106 to make it fall on the guide block 2309, and the collecting box 2310 collects the dust and impurities. The fourth spring 2308 can prevent the cleaning plate 2307 from interfering with the movement of the nozzle 2107. After cleaning, the external controller controls the electric push rod 2306 to reset, so as to realize the self-cleaning function of the nozzle 2107. During the operation of one group of nozzles 2107, the other group of nozzles 2107 performs self-cleaning, which does not affect the operation of the maintenance device, and can realize the seamless connection and replacement of the nozzle 2107, thereby improving the work efficiency, ensuring the uninterrupted operation of the maintenance device, and further improving the maintenance quality.
