Description

Technical Field

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

[0002] The original road and bridge project referred to the work of surveying, designing, constructing, maintaining, managing, etc. of roads and bridges. The foundation refers to the soil or rock mass that supports the foundation below the building

[0003] As the soil layer serving as the building foundation is divided into rock, gravel soil, sandy soil, silt, cohesive soil 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 artificially maintained to ensure that the quality of the foundation can meet the national requirements. During the process of maintaining the road and bridge foundation, it is necessary to sprinkle water on the road and bridge foundation for maintenance.

[0004] The existing device sprays water evenly on the surface of the foundation through a nozzle. However, due to the large amount of dust on the surface of the foundation, during the long-term spraying process of the maintenance device, the dust is likely to block the spraying holes at the bottom of the nozzle, making the sprayed water unable to be evenly sprayed, resulting in poor maintenance effect of the roadbed in the spraying blind area, reducing the quality of foundation maintenance, and requiring the operator to stop the operation of the maintenance device and clean or replace the nozzle. The operation is complex, the work efficiency is low, and the foundation maintenance effect is affected. For this reason, we propose a foundation maintenance device for road and bridge engineering management.

[0005] Combining the above problems, we will find that the existing foundation maintenance devices on the market are difficult to avoid the above-mentioned problems simultaneously during use, and even if they can be solved, they need to be solved with the cooperation of external tools, thus unable to achieve the desired effect. Therefore, we propose a foundation maintenance device for road and bridge engineering management. Summary of the Invention

The number of the servo motors 2103 is two, and the two servo motors 2103 are mounted at diagonal positions on the protection box 2102.

There are two groups of the second conveying rollers 2105, and the number of the second conveying rollers 2105 in each group is two. The surfaces of the first conveying roller 2104 and the second conveying roller 2105 are jointly drivingly connected with a conveyor belt 2106. The surface of the conveyor belt 2106 is fixedly provided with spray nozzles 2107. There are two groups of the spray nozzles 2107, and the number of the spray nozzles 2107 in each group is six. The two groups of spray nozzles 2107 are arranged oppositely. The surface of the spray nozzle 2107 is fixedly connected with a restraint sleeve 2108;

[0038] Inside the inner cavity of the protection box 2102, there is a cavity 2109 fixedly connected. At the bottom of the cavity 2109, there is a shunt pipe 2110 fixedly connected and communicated. The number of the shunt pipes 2110 is six. One end of the shunt pipe 2110 is fixedly connected and communicated with a third telescopic pipe 2111. One end of the third telescopic pipe 2111 is fixedly connected and communicated with a connecting pipe 2112.

One side of the mounting plate 2122 is fixedly connected with the surface of the connecting pipe 2112. On the surface of the connecting pipe 2112, there is a limiting frame 2117 fixedly connected. Inside the inner cavity of the limiting frame 2117, there is a first spring 2118 fixedly connected. One end of the first spring 2118 is fixedly connected with a trapezoidal stopper 2119. Through the combined use of the pressure plate 2114 and the fan-shaped grooves 2115, when the shunt pipe 2110 is filled with liquid, the pressure will drive the pressure plate 2114 to move downward, causing it to drive the connecting pipe 2112 to move downward, so that the connecting pipe 2112 is communicated with the nozzle 2107. The fan-shaped grooves 2115 can ensure the flow of liquid during the downward pressing process of the pressure plate 2114, and can realize the automatic connection function of the nozzle 2107, improving the maintenance efficiency. Through the cooperation of the limiting frame 2117, the first spring 2118 and the trapezoidal stopper 2119, after the connecting pipe 2112 is communicated with the nozzle 2107, it limits the connecting pipe 2112, avoiding the reset of the connecting pipe 2112 under the action of the spring telescopic rod 2116 due to the decrease in pressure, causing it to separate from the nozzle 2107 and resulting in waste of water resources, and further improving the maintenance quality;

[0039] On the surface of the nozzle 2107, there is a first sealing ring 2120 fixedly connected. The cross-sectional shape of the first sealing ring 2120 is trapezoidal. On one side of the nozzle 2107, there is a second sealing ring 2121 fixedly connected. The cross-sectional shape of the second sealing ring 2121 is concave-shaped. Through the combined use of the first sealing ring 2120 and the second sealing ring 2121, a double-layer sealing effect is formed at the connection between the connecting pipe 2112 and the nozzle 2107, avoiding liquid leakage, ensuring the spraying effect of the nozzle 2107 while avoiding waste of water resources, and improving the maintenance effect;

[0040] The limiting unit 22 includes a water pump 2201 fixedly installed on the top of the water storage tank 12. The water inlet of the water pump 2201 is fixedly communicated with a three-way solenoid valve 2202. One end of the three-way solenoid valve 2202 is communicated with the outside air, and one end of the three-way solenoid valve 2202 is fixedly communicated with a water inlet pipe 2203.

One end of the second water outlet pipe 2206 is fixedly communicated with a second telescopic pipe 2207. One end of the second telescopic pipe 2207 is fixedly communicated with a third water outlet pipe 2208. One end of the third water outlet pipe 2208 penetrates into the inner cavity of the protective box 2102. By setting the three-way solenoid valve 2202, air can be injected into the inner cavity of the first water outlet pipe 2204 before replacing the nozzle 2107, which is beneficial to the discharge of the water flow in the inner cavity of the first water outlet pipe 2204, avoids liquid residue from affecting the detachment of the restraining rod 2214 from the limiting sleeve and the detachment of the connecting pipe 2112 from the nozzle 2107, ensures the stability of the device operation, and improves the use effect of the maintenance device;

[0041] One end of the third water outlet pipe 2208 is fixedly communicated with a piston cylinder 2209. A piston plate 2210 is slidably connected in the inner cavity of the piston cylinder 2209. The surface of the piston cylinder 2209 is fixedly communicated with a fourth water outlet pipe 2211. One end of the fourth water outlet pipe 2211 is fixedly communicated with the top of the cavity 2109. One side of the piston plate 2210 is fixedly connected with a piston rod 2212. One end of the piston rod 2212 penetrates through the piston cylinder 2209 and is fixedly connected with an I-shaped plate 2213. One side of the I-shaped plate 2213 is fixedly connected with a restraining rod 2214. There are two groups of restraining rods 2214, and the number of each group of restraining rods 2214 is six. One end of the restraining rod 2214 penetrates into the inner cavity of the protective box 2102. An L-shaped block 2215 is fixedly connected to the surface of one group of restraining rods 2214. The restraining rod 2214 corresponds to the restraining sleeve 2108; through the cooperation of the piston cylinder 2209, the piston plate 2210 and the piston rod 2212, the water flow enters the inner cavity of the piston cylinder 2209 through the third water outlet pipe 2208, and then the liquid drives the piston plate 2210 to move, so that the liquid can flow into the fourth water outlet pipe 2211. The piston plate 2210 drives the I-shaped plate 2213 to move through the piston rod 2212, and the I-shaped plate 2213 drives the restraining rod 2214 to move, so that it is engaged with the corresponding restraining sleeve 2108 to limit the nozzle 2107, avoiding the problem of the nozzle 2107 bending the conveyor belt 2106 caused by excessive water pressure, and improving the maintenance quality;

[0042] A second spring 2216 is sleeved on the surface of the restraint rod 2214. One end of the second spring 2216 is fixedly connected to one side of the protection box 2102, and the other end of the second spring 2216 is fixedly connected to one side of the I-shaped plate 2213. The positions where the third water outlet pipe 2208 communicates with the piston cylinder 2209 and where the fourth water outlet pipe 2211 communicates with the piston cylinder 2209 are respectively located on both sides of the piston plate 2210 and are arranged oppositely. By setting the second spring 2216, when the water pump 2201 stops pouring water into the inner cavity of the first water outlet pipe 2204, under the combined action of multiple second springs 2216, the I-shaped plate 2213 moves outward, thereby driving the corresponding restraint rod 2214 to move, which can ensure the function of the restraint rod 2214 to disengage and realize the stable operation of the device.

[0043] By setting the cooperation of the replacement unit 21 and the limiting unit 22, the purpose of quickly and automatically replacing the nozzle 2107 can be achieved. The nozzle 2107 can be replaced at a high frequency, ensuring that the nozzle 2107 will not be blocked during use, so that there will be no spraying blind area during operation, thereby improving the quality of foundation maintenance, reducing the working time for the operator to clean or replace the nozzle 2107, reducing the labor intensity of the operator, and improving the working efficiency while ensuring the foundation maintenance effect.

[0044] 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 sucks in external air into the inner cavity of the first water outlet pipe 2204 through the three-way solenoid valve 2202. The air will push the liquid in the inner cavities of the first water outlet pipe 2204, the first telescopic pipe 2205, the second water outlet pipe 2206, the second telescopic pipe 2207, the third water outlet pipe 2208, the piston cylinder 2209, the fourth water outlet pipe, the cavity 2109, the shunt pipe 2110, the third telescopic pipe 2111 and the connecting pipe 2112 to be discharged. 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 combined action of a plurality of second springs 2216, the I-shaped plate 2213 moves outward, thereby driving the corresponding restraint rod 2214 to move. The restraint rod 2214 disengages from the corresponding restraint sleeve 2108, releasing the limit on the nozzle 2107. At the same time, when the set of restraint rods 2214 at the bottom moves outward, it drives the L-shaped block 2215 to move outward, releasing the limit on the connecting pipe 2112. The connecting pipe 2112 resets under the action of the spring telescopic rod 2116, so that it disengages from the nozzle 2107. At this time, the external controller controls the servo motor 2103 to start. The output shaft of the servo motor 2103 drives the first conveying roller 2104 to rotate. The first conveying roller 2104 and the second conveying roller 2105 cooperate to drive the conveyor belt 2106 to move, so that the upper and lower groups of nozzles 2107 are exchanged. After the exchange is completed, the external controller controls the water pump 2201 and the three-way solenoid valve 2202 to start. 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 under the action of the water pump 2201, and flows into the inner cavity of the piston cylinder 2209 through the first telescopic pipe 2205, the second water outlet pipe 2206, the second telescopic pipe 2207 and the third water outlet pipe 2208. Then the liquid drives the piston plate 2210 to move, so that the water flow can flow into the fourth water outlet pipe 2211. The piston plate 2210 drives the I-shaped plate 2213 to move through the piston rod 2212. The I-shaped plate 2213 drives the restraint rod 2214 to move, so that it engages with the corresponding driving sleeve, limiting the upper and lower groups of nozzles 2107. The water flow enters the inner cavity of the shunt pipe 2110 through the fourth water outlet pipe 2211 and the cavity 2109. The water pressure drives the pressure plate 2114 to move downward, so that it drives the connecting pipe 2112 to move downward, so that the connecting pipe 2112 is communicated with the nozzle 2107. When the connecting pipe 2112 moves to the bottommost position, when the L-shaped block 2215 contacts the trapezoidal stop block 2119, it compresses the corresponding first spring 2118 through the trapezoidal stop block 2119, so that the trapezoidal stop block 2119 moves inward. When the L-shaped block 2215 disengages from the trapezoidal stop block 2119, the trapezoidal stop block 2119 resets under the action of the first spring 2118. The cooperation with the L-shaped block 2215 can realize the limiting function of the connecting pipe 2112. Through the combined use of the first sealing ring 2120 and the second sealing ring 2121,A double - layer sealing effect is formed at the connection between the connecting pipe 2112 and the nozzle 2107 to avoid liquid leakage, waste of water resources, ensure the spraying effect of the nozzle 2107, improve the maintenance effect, and the time required for the whole process is less. Therefore, the purpose of quickly and automatically replacing the nozzle 2107 can be achieved, the nozzle 2107 can be replaced at a high frequency, ensuring that the nozzle 2107 will not be blocked during use and there will be no spraying blind area during operation, thereby improving the foundation maintenance quality.

[0047] The self - cleaning mechanism 23 includes an impeller sleeve 2301 fixedly communicated with the surface of the second water outlet pipe 2206. The number of impeller sleeves 2301 is six.

One end of the cleaning brush 2305 penetrates through the buffer box 2302. Two electric push rods 2306 are fixedly connected to the top of the protective box 2102. The output ends of the electric push rods 2306 are fixedly connected with the surface of the second water outlet pipe 2206; By setting the impeller sleeve 2301, the flowing water through the second water outlet pipe 2206 can drive the impeller sleeve 2301 to rotate. The impeller sleeve 2301 will drive the buffer box 2302 to rotate, thereby driving the cleaning brush 2305 to rotate to clean the surface of the nozzle 2107, avoiding dust from blocking the nozzle 2107 and thus affecting the spraying and maintenance effect;

[0048] A cleaning plate 2307 is rotatably connected to the inner cavity of the protective box 2102 through a rotating shaft. The cleaning plate 2307 is made of sponge. The number of cleaning plates 2307 is two, and the two cleaning plates 2307 are arranged in an "eight" shape. One side of the cleaning plate 2307 is fixedly connected with a fourth spring 2308. One end of the fourth spring 2308 is fixedly connected with the inner cavity of the protective box 2102. By setting the cleaning plate 2307, it is convenient to guide the dust falling on the surface of the conveyor belt 2106 to fall on the guide block 2309, realizing the collection of dust and impurities and improving the work efficiency;

[0049] The inner cavity of the protection box 2102 is fixedly connected with a material guide block 2309 , the number of the material guide blocks 2309 is two, and a collection box 2310 is slidably connected between the two material guide blocks 2309 .

[0050] 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.
