Description

Technical Field

[0001] The utility model relates to the technical field of tunnel cleaning, and more specifically, to a high-speed railway tunnel cleaning vehicle. Background Art

[0002] Currently, during the construction of railway tunnels, dust will adhere to the inner wall and the roadbed of the tunnel. During the operation of railway tunnels, especially for passenger and freight dual-use lines, after long-term operation, the internal oil stains and dust adhere seriously. When the train enters the tunnel at high speed, a pressure difference is generated inside the tunnel, resulting in flying dust, which seriously affects the driver's line of sight and the comfort of passengers. Therefore, when the line is delivered, the tunnel must be cleaned to meet the tunnel delivery standards.

[0003] The utility model patent document with the publication number of CN212052512U discloses a tunnel cleaning device. By fixing the cleaning liquid tank on the vehicle body, connecting the input end of the cleaning liquid pump with the cleaning liquid tank, and connecting the output end of the cleaning liquid pump with the cleaning liquid pipe, the cleaning liquid in the cleaning liquid tank can flow into the cleaning liquid pipe; secondly, by fixing the first bracket on the vehicle body and fixing at least one cleaning liquid pipe on the first bracket to improve the stability of the cleaning liquid pipe; thirdly, by connecting at least two first nozzles with the cleaning liquid pipe to spray the cleaning liquid onto the inner wall of the tunnel; thirdly, by rotatably connecting one end of the main shaft with the supporting part and making the other end of the main shaft pass through the fixing frame and then connecting it with the driving device, the driving device drives the main shaft to rotate; thirdly, by arranging the brush around the main shaft and making the brush fit with the inner wall of the tunnel to brush the tunnel; thirdly, by fixing the water tank on the vehicle body, connecting the input end of the water pump with the water tank, and connecting the output end of the water pump with the water pipe, the water in the water tank can flow into the water pipe; secondly, by fixing the second bracket on the vehicle body and fixing at least one water pipe on the second bracket to improve the stability of the water pipe; thirdly, by connecting at least two second nozzles with the water pipe to spray water onto the inner wall of the tunnel, so as to realize the cleaning of the inner wall of the tunnel. By spraying the cleaning liquid on the inner wall of the tunnel, then spreading the cleaning liquid evenly with the brush and brushing the tunnel, and then spraying water on the inner wall of the tunnel to wash away the cleaning liquid, the cleanliness of the tunnel can be ensured. At the same time, by arranging the supporting part on the side wall of the vehicle body, the brush can extend out of the vehicle body to avoid interference between the vehicle body and the inner wall of the tunnel when the brush brushes the inner wall of the tunnel.

[0004] Although the above tunnel cleaning device can solve the corresponding technical problems, its structure is simple and its functions are relatively single. It is difficult for its first nozzle and second nozzle to clean the inner wall of the tunnel comprehensively. Moreover, when the brush is used to scrub the inner wall of the tunnel, the dirt will directly fall onto the roadbed, causing secondary pollution, thereby reducing the tunnel cleaning effect. Therefore, a high-speed rail tunnel cleaning vehicle is proposed. Summary of the Utility Model

[0056] The cleaning mechanism 200 is used to comprehensively clean the inside of the high-speed rail tunnel;

[0057] The dust suction mechanism 300 is used to perform dust suction and dirt suction operations on the roadbed;

[0058] The driving mechanism 400 is used to provide a power source for the cleaning mechanism 200 and the dust suction mechanism 300;

[0060] As Figures 1 - 11 shown, the difference between the high-speed rail tunnel cleaning vehicle provided in this embodiment and Embodiment 1 is:

[0061] The cleaning mechanism 200 includes a top surface cleaning component 210, a side surface cleaning component 220, a bottom surface cleaning component 230 and a nozzle 240. The side surface cleaning component 220, the top surface cleaning component 210, the driving mechanism 400 and the dirt storage mechanism 500 are sequentially arranged on the top of the flat car 100 along the length direction of the flat car 100, and the bottom surface cleaning component 230 is arranged at the bottom of the flat car 100;

[0063] The telescopic member A includes a cylinder A212 vertically installed on one side of the top of the flat car 100. A support rod A213 is installed at the output end of the cylinder A212 along the width direction of the flat car 100. At the center of the top of the support rod A213, a support rod B214 is fixedly connected perpendicular to it. At the top of the support rod B214, a support rod C215 is fixedly connected. The support rod C215 and the water pipe A211 are fixedly connected by a plurality of equally spaced clamps. A number of nozzles 240 are equally spaced and communicated on the top of the water pipe A211. Both the support rod C215 and the water pipe A211 are in an arc shape, and the support rod C215 and the water pipe A211 are concentrically arranged. By starting the cylinder A212, the height of the water pipe A211 can be adjusted, which can not only meet the usage requirements of tunnels with different heights during cleaning, but also reduce the overall occupied space of the top surface cleaning assembly 210 during transfer transportation. Both ends of the support rod A213 are fixedly connected with a guide rod 216. The guide rod 216 is parallel to the support rod B214. The top end of the guide rod 216 is fixedly connected with the support rod C215. A conduit 217 is slidably sleeved on the lower part of the surface of the guide rod 216.

[0074] The telescopic member C includes a cylinder C350 hinged between the mounting plate 310 and the housing 320. Two groups of link rods B360 are also hinged between the mounting plate 310 and the housing 320. Each group of link rods B360 has two arranged along the width direction of the flat car 100. By starting the cylinder C350, the housing 320 can be driven to move up and down, which can closely attach the housing 320 to the substrate during work to ensure the dust and dirt suction effect, and keep the housing 320 away from the substrate during transfer for convenient transfer transportation.

[0078] Working principle:

[0079] a. Cleaning operation:

[0080] S1. Start the cylinder A212, so that the output end of the cylinder A212 drives the support rod A213, support rod B214, support rod C215, and water pipe A211 to move upward. The support rod A213 drives the guide rod 216 to slide in the inner cavity of the conduit 217 until the water pipe A211 approaches the inner top surface of the tunnel.

[0081] S2. Start cylinder B2261 so that the output end of cylinder B2261 drives the struts D224 on both sides to flip open through connecting rod A2262. The struts D224 drive the corresponding water pipes B221 and auxiliary parts 225 to rotate synchronously until the struts D224 on both sides and the strut D224 in the middle are on the same straight line.

[0082] S3. Start robotic arm 223 so that the free end of robotic arm 223 drives strut D224, water pipe B221, auxiliary part 225 and folding part 226 to move freely in three-dimensional space until water pipe B221 is close to the inner side of the tunnel and water pipe C2252 is close to the inner bottom surface of the tunnel.

[0083] S4. Start the high-pressure water pump and the corresponding control valves in high-pressure water power cabin 410. The high-pressure water pump transports the water stored in high-pressure water power cabin 410 to water pipes A211, B221, C2252, D233, E234 and F235 through high-pressure pipelines, and finally sprays it onto the inner wall surface of the tunnel through nozzle 240, thus realizing the all-round cleaning operation of the inner wall surface of the tunnel.

[0084] b. Dust and dirt suction operation:

[0085] S1. Start the three cylinders C350 in sequence according to the left, middle and right order. The output end of cylinder C350 drives housing 320 to move towards the roadbed until housing 320 descends to a suitable position.

[0086] S2. Start the three motors 370 in sequence according to the left, middle and right order. The output shaft of the motor drives roller 380 and the brush to rotate, and thus the track can be cleaned by the brush.

[0087] S3. Start the high-pressure air pump and the corresponding control valves in dust suction power cabin 420. The high-pressure air pump sucks air through dust suction hood 330, hose 340 and high-pressure pipeline, creating negative pressure in housing 320, and thus the dirt in housing 320 can be sucked into the inner cavity of garbage cabin 510 for unified collection.

[0088] c. Garbage dumping operation:

[0089] First, start cylinder D530 to flip open hatch 520, and then start cylinder E540 to flip and tilt garbage cabin 510, so that the dirty garbage collected in garbage cabin 510 can be dumped into the garbage dump.
