Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 The utility model provides a technical solution: a maintenance vehicle for guardrail renovation, comprising a top plate 1 and a clamping mechanism 2, wherein the clamping mechanism 2 is provided on one side of the surface of the top plate 1, and a processing mechanism 3 is provided at one end of the clamping mechanism 2;

[0028] The clamping mechanism 2 includes a groove 201, a first rotating groove 202, a connecting groove 203, a positioning rod 204, a threaded rod 205, a first connecting plate 206, a sleeve 207, a threaded sleeve 208, a first motor 209 and a second connecting plate 210. A groove 201 is provided on one side of the surface of the top plate 1, and a first rotating groove 202 is provided on both sides of the groove 201. A connecting groove 203 is provided on the surface of the groove 201. One end of the groove 201 is fixedly connected to the positioning rod 204. The interior of the first rotating groove 202 is embedded with the threaded rod 205, and the interior of the connecting groove 203 is embedded with the first connecting plate 206. The surface of the positioning rod 204 is embedded with the sleeve 207. The surface of the threaded rod 205 is threadedly connected to the threaded sleeve 208. One side of the threaded rod 205 is connected to the first motor 209. One end of the sleeve 207 is fixedly connected to the second connecting plate 210. Through the arrangement of the groove 201, the first rotating groove 202, the connecting groove 203, the positioning rod 204, the threaded rod 205, the first connecting plate 206, the sliding sleeve 207, the threaded sleeve 208, the first motor 209 and the second connecting plate 210, a groove 201 and a clamping mechanism 2 are provided on one side of the surface of the top plate 1. The clamping mechanism 2 is used to fix and adjust the guardrail. The threaded rod 205 drives the threaded sleeve 208 to move along its axial direction through the first motor 209 to form a sliding structure. The positioning rod 204 cooperates with the sliding sleeve 207 to ensure the stability and accuracy of the clamping mechanism 2. When the first motor 209 rotates, the threaded rod 205 drives the threaded sleeve 208, and then adjusts the clamping state of the clamping mechanism 2 through the sliding sleeve 207 and the second connecting plate 210. The clamping mechanism 2 can be more flexibly fixed as needed through the through design of three groups of grooves 201.

[0029] Furthermore, there are three groups of grooves 201, and the three groups of grooves 201 are interconnected through the connecting grooves 203. Through the setting of the grooves 201, the grooves 201 provide installation positions for multiple components in the clamping mechanism 2, and its interior is embedded with components such as a threaded rod 205, a first connecting plate 206, a sleeve 207 and a threaded sleeve 208. These components are embedded and fixed by the grooves 201, so that each component can move on a specified track or position, ensuring that the structure of the device is stable and will not deviate or loosen during operation. At the same time, the grooves 201 form a sliding guide by providing an embedding space for the threaded rod 205 and the sleeve 207. When the sleeve 207 slides in the groove 201, the sliding stability is maintained, and the clamping mechanism 2 can be more precise when adjusting the guardrail, avoiding shaking or errors during the clamping process.

[0030] Furthermore, two groups of positioning rods 204 are provided, and the positioning rods 204 are provided on both sides of the threaded rod 205. Through the setting of the positioning rods 204, the positioning rods 204 are distributed on both sides of the threaded rod 205 through the setting of two groups, forming a symmetrical structure. The positioning rods 204 on both sides work together to make the entire clamping mechanism 2 more stable during the adjustment process, avoiding shaking or tilting caused by uneven force on one side, which is particularly important during the movement of the maintenance vehicle.

[0031] Furthermore, the sliding sleeve 207 and the threaded sleeve 208 are both embedded in the inside of the groove 201, and the sliding sleeve 207 and the threaded sleeve 208 are connected by the first connecting plate 206. Through the setting of the first connecting plate 206, the first connecting plate 206 connects the two sliding components of the sliding sleeve 207 and the threaded sleeve 208 together to form an integral structure. Through this connection, the first connecting plate 206 enables the threaded rod 205 to rotate and drive the threaded sleeve 208 to synchronously drive the sliding sleeve 207 to move along the positioning rod 204, thereby realizing the synchronous movement of the clamping mechanism 2.

[0032] Furthermore, the threaded sleeve 208 forms a mutual sliding structure with the threaded rod 205 through the first motor 209, and the positioning rod 204 and the sliding sleeve 207 form a mutual sliding structure. Through the setting of the sliding sleeve 207, the sliding sleeve 207 is engaged with the positioning rod 204 to form a sliding matching structure. The sliding sleeve 207 can slide smoothly axially along the positioning rod 204, playing a guiding role, ensuring that the clamping mechanism 2 has good linear motion characteristics when adjusting or moving, and preventing the clamping mechanism 2 from deviating from the set track.

[0033] Furthermore, one end of the second connecting plate 210 is connected to a threaded sleeve 208, and two groups of threaded sleeves 208 are provided. Through the setting of the threaded sleeve 208, the threaded sleeve 208 and the threaded rod 205 are threadedly connected to form a sliding transmission structure. When the threaded rod 205 rotates under the drive of the first motor 209, the threaded sleeve 208 moves along the axial direction of the threaded rod 205 to realize the linear displacement adjustment of the clamping mechanism 2. This transmission mechanism of the threaded sleeve 208 is the core of the displacement adjustment of the entire clamping mechanism 2.

[0034] Furthermore, the processing mechanism 3 includes a connecting box 301, a feeding port 302, a storage box 303, a universal wheel 304, a second rotating groove 305, a protective cover 306, a water pump 307, a rotating brush 308, a mounting plate 309, a second motor 310 and a nozzle 311. The other side of the second connecting plate 210 is fixedly connected to the connecting box 301, a feeding port 302 is provided at one end of the connecting box 301, a storage box 303 is provided inside the connecting box 301, a universal wheel 304 is installed at one end of the connecting box 301, a second rotating groove 305 is provided on one side of the surface of the connecting box 301, the internal thread of the feeding port 302 is connected to the protective cover 306, one side of the storage box 303 is connected to the water pump 307, the rotating brush 308 is embedded in the second rotating groove 305, the other side of the water pump 307 is connected to the mounting plate 309, one side of the rotating brush 308 is connected to the second motor 310, and the mounting plate 309 is provided on the A spray head 311 is installed on one side. Through the arrangement of the connecting box 301, the feed port 302, the storage box 303, the universal wheel 304, the second rotating groove 305, the protective cover 306, the water pump 307, the rotating brush 308, the mounting plate 309, the second motor 310 and the spray head 311, when the clamping mechanism 2 fixes the guardrail, the processing mechanism 3 starts to work. The processing mechanism 3 is connected to the clamping mechanism 2 through the second connecting plate 210. The feed port 302 is used to provide raw materials for the processing process. The materials are stored in the storage box 303. The water pump 307 extracts liquid from the storage box 303, connects the mounting plate 309 and the spray head 311, and the spray head 311 sprays the liquid evenly. During the processing process, the rotating brush 308 is driven to rotate by the second motor 310. The brush contacts the guardrail in the second rotating groove 305 to perform cleaning or processing operations. The universal wheel 304 enables the processing mechanism 3 to move flexibly to facilitate processing at different positions.

[0035] Furthermore, the main body of the second motor 310 is installed on the connecting box 301, and the rotating brush 308 forms a mutually rotating structure with the connecting box 301 through the second motor 310. Through the setting of the rotating brush 308, the main function of the rotating brush 308 is to contact the surface of the guardrail through rotation to perform cleaning, decontamination or other processing operations. It can remove dust, impurities or dirt on the surface of the guardrail to ensure that the processed guardrail remains clean before renovation. At the same time, since the rotating brush 308 can be driven by the second motor 310 to rotate continuously, it can evenly process the surface of the guardrail. The rotating movement of the rotating brush 308 ensures that each area of ​​the guardrail surface can be processed with the same force, thereby ensuring the uniformity and consistency of the processing effect.

[0036] Furthermore, two groups of mounting plates 309 are provided on the connection box 301, and the mounting plates 309 are provided on both sides of the rotating brush 308. Through the setting of the mounting plates 309, the mounting plates 309 play a role of structural bearing, through which the rotating brush 308, the nozzle 311 and other components can be firmly connected to the processing mechanism 3, and the load or pressure generated by these components during the working process can be shared, thereby ensuring the stability and durability of the entire device.

[0037] Furthermore, four groups of nozzles 311 are arranged on the mounting plate 309, and the nozzles 311 are distributed at equal intervals on the mounting plate 309. Through the setting of the nozzles 311, the main function of the nozzles 311 is to spray liquid onto the guardrail for cleaning, lubrication or other treatment processes. By evenly spraying the liquid, the nozzles 311 ensure that the surface of the guardrail can be completely covered, thereby improving the cleaning or treatment effect. At the same time, the nozzles 311 are used in conjunction with the rotating brush 308. The cleaning liquid is first sprayed through the nozzles 311, and then mechanical friction is performed through the rotating brush 308 to achieve a more thorough cleaning effect. The liquid can soften dirt or lubricate the surface of the guardrail, helping the rotating brush 308 to more efficiently remove dirt or perform surface polishing.

[0038] Working principle: A groove 201 and a clamping mechanism 2 are provided on one side of the surface of the top plate 1. The clamping mechanism 2 is used to fix and adjust the guardrail. The threaded rod 205 drives the threaded sleeve 208 to move along its axial direction through the first motor 209 to form a sliding structure. The positioning rod 204 cooperates with the sliding sleeve 207 to ensure the stability and accuracy of the clamping mechanism 2. When the first motor 209 rotates, the threaded rod 205 drives the threaded sleeve 208, and then adjusts the clamping state of the clamping mechanism 2 through the sliding sleeve 207 and the second connecting plate 210. The clamping mechanism 2 can achieve more flexible fixation through the through-connection design of the three groups of grooves 201 as needed. After the clamping mechanism 2 fixes the guardrail, the processing mechanism 3 starts to work. The processing mechanism 3 is connected to the clamping mechanism 2 through the second connecting plate 210. The feed port 302 is used to provide raw materials for the processing process. The materials are stored in the storage box 303. The water pump 307 extracts liquid from the storage box 303, connects the mounting plate 309 and the nozzle 311, and the nozzle 311 sprays the liquid evenly. During the processing, the rotating brush 308 is driven to rotate by the second motor 310. The brush contacts the guardrail in the second rotating groove 305 to perform cleaning or processing operations. The universal wheel 304 enables the processing mechanism 3 to move flexibly to facilitate processing at different positions.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
