DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0030] Reference Figures 1-10The present application provides: a road bridge guardrail maintenance equipment with a dustproof structure, comprising a vehicle body 1, an automatic protection door 2 and a maintenance assembly 3, the maintenance assembly 3 is arranged in the vehicle body 1, the vehicle body 1 is internally provided with a cavity for storing water, the vehicle body 1 is the main structure of the whole equipment, and is used for bearing all components such as the automatic protection door 2, the maintenance assembly 3 and the cavity for storing water. It provides a mobile platform, so that the maintenance equipment can be conveniently moved to the guardrail position needing maintenance. The maintenance assembly 3 can be extended from the vehicle body 1 for cleaning and maintaining the guardrail, the automatic protection door 2 can open or close to protect the maintenance assembly 3 in the vehicle body 1, so as to avoid that the maintenance assembly 3 accumulates a large amount of dust when not in use, when the maintenance assembly 3 needs to work, the automatic protection door 2 is opened, allowing the maintenance assembly 3 to extend out of the vehicle body 1 to work, when the maintenance work is completed, the automatic protection door 2 is closed, the maintenance assembly 3 is resealed in the vehicle body 1, and dust is prevented from entering. The maintenance assembly 3 further comprises a turnover assembly 33 and a cleaning assembly 34, the cleaning assembly 34 is symmetrically provided with two groups on the turnover assembly 33, the external cleaning assembly 34 can be turned over through the turnover assembly 33, so that the external cleaning assembly 34 is conveniently moved to the outside of the guardrail, the maintenance assembly 3 is extended from the vehicle body 1 when needed, the turnover action of the turnover assembly 33 enables the cleaning assembly 34 to be moved to the outside of the guardrail to perform cleaning work. After cleaning, the maintenance assembly 3 is retracted into the vehicle body 1. The turnover assembly 33 comprises a fixed frame 331 and a turnover frame 332, one side of the fixed frame 331 and one side of the turnover frame 332 are movably connected through a shaft, the turnover frame 332 is turned over relative to the fixed frame 331, the turnover assembly 33 further comprises a telescopic driving piece 335, the telescopic driving piece 335 is fixed on the fixed frame 331, and the output end of the telescopic driving piece 335 is connected with a rack 334, the rack 334 is engaged with a first gear 333, the first gear 333 is fixed on the shaft on the turnover frame 332 and the fixed frame 331, when the rack 334 is driven to move by the telescopic driving piece 335, the first gear 333 is driven to rotate, and then the turnover frame 332 is driven to turn over through the shaft on the turnover frame 332 and the fixed frame 331, so that the external cleaning assembly 34 is facilitated to contact the outside of the guardrail. Through the mobility of the vehicle body 1, the protection of the automatic protection door 2 and the high efficiency of the maintenance assembly 3, the comprehensive cleaning and maintenance of the bridge guardrail are realized. The ingenious design of the turnover assembly 33 and the cleaning assembly 34 makes the cleaning work more flexible and efficient. The working principle of the whole equipment is clear, the structure is compact, and the efficiency and quality of the guardrail maintenance can be significantly improved.

[0031] In this embodiment, when the device moves to the guardrail, the turnover frame 332 is perpendicular to the fixed frame 331 in advance, and when the device approaches the guardrail, the telescopic drive 335 moves, the rack 334 is driven to move by the telescopic drive 335, and then the first gear 333 rotates, so that the turnover frame 332 is parallel to the fixed frame 331. At this time, the cleaning assembly 34 on the outside will be outside the guardrail, and the outside of the guardrail will be cleaned. The problem that the traditional device cleaning roller cannot extend to the outside of the guardrail or the lifting structure is used, resulting in a long stroke of the lifting structure and a large size of the device is solved.

[0032] Two cleaning assemblies 34 are arranged on the fixed frame 331 and the turnover frame 332 respectively. The cleaning assembly 34 comprises a cleaning roller body 341 and a movable adjusting member 345, and the movable adjusting member 345 can move back and forth to adjust the distance between the two cleaning roller bodies 341. Through the movement of the movable adjusting member 345, the two cleaning roller bodies 341 can move closer or farther away from each other, so as to adapt to guardrails of different widths or shapes, and improve the flexibility and efficiency of cleaning. The cleaning roller body 341 is movably connected to the bottom of the movable adjusting member 345 through a shaft, and the shaft inside the cleaning roller body 341 is hollow. A plurality of through holes are formed in the outer part of the cleaning roller body 341. Water is transported into the shaft on the cleaning roller body 341 and discharged from the through holes on the cleaning roller body 341, which is used to clean the dust on the guardrail. This design allows water to be transported into the cleaning roller body 341 through the shaft and sprayed out of the through holes, which works together with the rotating roller body to more effectively clean the guardrail. The cleaning assembly 34 further comprises a third rotating drive 342, a second gear 343 and a third gear 344. The third gear 344 is fixed on the shaft of the cleaning roller body 341, and the third rotating drive 342 is fixed on the bottom of the movable adjusting member 345. The output end of the third rotating drive 342 penetrates through the movable adjusting member 345 and is connected with the second gear 343. The second gear 343 is engaged with the third gear 344. The third rotating drive 342 drives the second gear 343 to rotate, and the third gear 344 drives the cleaning roller body 341 to rotate, which is used to clean the dust on the guardrail. These components constitute a transmission system for driving the cleaning roller body 341 to rotate. When the third rotating drive 342 is started, it drives the second gear 343 to rotate, and then drives the third gear 344 and the shaft of the cleaning roller body 341 to rotate through gear transmission, so as to realize the rotating cleaning action of the cleaning roller body 341. In summary, the cleaning assembly 34 realizes efficient and comprehensive cleaning of the bridge guardrail through its unique structure and working principle. At the same time, the adjustable cleaning roller spacing and water spraying cleaning function make the device adapt to different types and sizes of guardrails, and improve the practicality and flexibility of the device.

[0033] The cleaning assembly 34 is also provided with a spraying assembly 35 for pumping water in the cavity of the vehicle body 1 into the cleaning roller body 341 and spraying it out. The spraying assembly 35 comprises a main pipe 352 and a shunt pipe 353, and the shunt pipe 353 is connected with a movable joint 355 at one end, which is arranged on the shaft of the cleaning roller body 341. This design allows the cleaning roller body 341 to rotate while still maintaining connection with the shunt pipe 353, ensuring continuous supply of water flow. The shunt pipe 353 is clamped with a clamping piece 354, which is fixed on the movable adjusting piece 345. Regardless of how the movable adjusting piece 345 moves to adjust the distance between the cleaning roller bodies 341, the shunt pipe 353 can maintain a stable position and will not fall off due to vibration or movement.

[0034] In this embodiment, when water flows into the hollow shaft inside the cleaning roller body 341, it is sprayed out through the through hole on the shaft. These sprayed water works together with the rotating cleaning roller body 341 to spray and clean the guardrail surface. The addition of the spraying assembly 35 makes the cleaning process more efficient and thorough, and can more effectively remove dust and dirt on the guardrail.

[0035] The shunt pipe 353 is connected with the main pipe 352 at one end, and the main pipe 352 is connected with the pump body 351 at one end. The pump body 351 is fixed in the cavity in the vehicle body 1, and the pump body 351 pumps water in the cavity of the vehicle body 1 into the cleaning roller body 341 for spraying to clean dust on the guardrail.

[0036] The maintenance assembly 3 comprises a moving assembly 31 fixed inside the vehicle body 1, which is used to drive the cleaning assembly 34 to extend out of the vehicle body 1 to clean the guardrail. The moving assembly 31 comprises a first rotary drive 311, a lead screw 312, a slide rail 313, and a support plate 315. The slide rail 313 is fixed inside the vehicle body 1, and a sliding block 314 is slidingly arranged on the slide rail 313, and the support plate 315 is fixed on the sliding block 314. The lead screw 312 is installed in the vehicle body 1 through a bearing seat. The output end of the first rotary drive 311 is fixedly connected with one end of the lead screw 312, and the first rotary drive 311 is used to drive the lead screw 312 to rotate. The lead screw 312 is engaged with a threaded sleeve inside the support plate 315 through threads thereon, thereby driving the support plate 315 to move back and forth.

[0037] In this embodiment, when the cleaning component 34 needs to be extended for cleaning, the first rotary drive 311 is activated. Its output end begins to rotate, driving the lead screw 312, which is fixedly connected to it, to rotate. The thread on the lead screw 312 engages with the threaded sleeve inside the support plate 315. As the lead screw 312 rotates, the support plate 315 experiences a forward pushing or pulling force (depending on the rotation direction of the lead screw 312) through the thread transmission principle. Since the support plate 315 is fixed on the slider 314, and the slider 314 is slidably mounted on the slide rail 313, the movement of the support plate 315 will cause the slider 314 to slide on the slide rail 313. In this way, the cleaning component 34 is driven to extend from the vehicle body 1. By changing the rotation direction of the first rotary drive 311, the reciprocating movement of the support plate 315 and the cleaning component 34 can be achieved. After cleaning is completed, the cleaning component 34 can be retracted into the vehicle body 1 to protect it from dust and damage.

[0038] The moving component 31 is also provided with a cleaning roller lifting component 32, which is used to move the cleaning component 34 up and down. The cleaning roller lifting component 32 allows the cleaning component 34 to be adjusted according to the height of the guardrail to adapt to guardrails of different heights. The cleaning roller lifting component 32 includes a guide rail 321, which is fixed on both sides of the support plate 315. The cross-section of the guide rail 321 is "I" shaped. A connector 324 is provided on the outer side of the guide rail 321. Several traveling wheels 325 are movably arranged on the inner side of the connector 324 through a shaft. The traveling wheels 325 are in contact with the side of the guide rail 321. A bracket 322 is fixed on one side of the connector 324, and the bracket 322 is fixedly connected to the fixed frame 331.

[0039] The cleaning roller lifting assembly 32 also includes a transmission assembly 323, which has a self-locking function. The transmission assembly 323 is used to prevent the cleaning assembly 34 from suddenly descending due to its own weight. The transmission assembly 323 includes a protective shell 3234, which is fixed to the outside of the connecting member 324. A worm gear 3231 and a worm 3232 are provided in the protective shell 3234. The center of the worm gear 3231 is fixed on the shaft of the traveling wheel 325, and the worm 3232 meshes with the worm gear 3231. A second rotary drive 3233 is fixed to the outside of the protective shell 3234. The output end of the second rotary drive 3233 is fixedly connected to one end of the worm 3232. When the second rotary drive 3233 is started, it drives the worm 3232 to rotate, thereby causing the worm gear 3231 to rotate, which in turn causes the traveling wheel 325 to rotate on the guide rail 321.

[0040] In this embodiment, when the height of the cleaning assembly 34 needs to be adjusted, the second rotary drive 3233 is started. Its output end starts to rotate and drives the worm 3232 to rotate, so that the traveling wheel 325 moves on the guide rail 321, and then the connecting piece 324 drives the fixed frame 331 to move up and down, and the cleaning roller body 341 moves up and down, so as to clean the guardrails of different heights. When the worm 3232 stops rotating, the worm gear 3231 will be locked at the current position to prevent the cleaning assembly 34 from suddenly falling due to gravity. This self-locking function ensures the stability and safety of the cleaning assembly 34 during height adjustment.

[0041] Working principle: when in use, after water is pre-filled into the cavity in the vehicle body 1, the device is moved to the guardrail, at this time, the turnover frame 332 is prependicular to the fixed frame 331. When the device approaches the guardrail, the rack 334 is moved by the movement of the telescopic drive 335, and then the first gear 333 rotates, so that the turnover frame 332 is parallel to the fixed frame 331. At this time, the outer cleaning assembly 34 will be outside the guardrail. Then, the cleaning roller body 341 on both sides of the guardrail is in contact with the guardrail by the automatic movement of the movable adjusting piece 345. At this time, the third rotary drive 342 is started to rotate the second gear 343, which drives the third gear 344 to rotate, and then the cleaning roller body 341 rotates at high speed to clean the dust on the guardrail. In order to better clean the dust on the guardrail, the pump body 351 is started to pump the water in the vehicle body 1 into the main pipeline 352, and then the water flows into the cleaning roller body 341 through the shunt pipe 353, and is sprayed out of the hole in the cleaning roller body 341 to clean the dust on the guardrail. Then, the second rotary drive 3233 is started to rotate the worm 3232, which in turn rotates the worm gear 3231, which drives the shaft to rotate the traveling wheel 325, and then the connecting piece 324 drives the fixed frame 331 to move up and down, and the cleaning roller body 341 moves up and down to clean the guardrails of different heights. After the guardrail is cleaned, the first rotary drive 311 is started to rotate the lead screw 312, which in turn moves the support plate 315, so as to facilitate the cleaning assembly 34 to be retracted into the vehicle body 1. The automatic protection door 2 is moved to seal the vehicle body 1, so as to avoid accumulation of too much dust on the maintenance assembly 3 when the device is not used for a long time.

[0042] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
