Description

Technical Field

[0001] This utility model relates to the field of sweeper technology, specifically to a roller brush device for a guardrail cleaning vehicle. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the scale of my country's highway mileage is increasing, and the number of cars is also constantly growing. Especially in cities, during morning and evening rush hours, urban roads are congested with vehicles. Therefore, it is necessary to install guardrails in the center or on both sides of the road to maintain traffic order for pedestrians and vehicles. However, there is a lot of dust on the road, and the guardrails are easily covered with dirt and become dull in color, which affects the appearance of the city. Therefore, guardrail cleaning vehicles are needed to clean the guardrails. According to the search, Chinese patent application number "CN202322090317.6" discloses a road guardrail cleaning vehicle with a liftable roller, including a roller brush and a drive structure. The drive structure is fixedly installed on the left side of the telescopic arm. The drive structure is equipped with a shaft, and the roller brush is installed vertically on the shaft. The shaft has an air duct inside, and a drain pipe is fixedly installed on the outside of the shaft. The air duct has exhaust ports arranged vertically on the outside.

[0003] In the process of implementing this utility model, the inventors discovered the following problems with the existing technology: Because the brushes will wear down during long-term use, they need to be replaced regularly. However, the existing brush assembly is a one-piece design, with the brushes and the rotating shaft molded as one piece. If some brushes are damaged, the entire rotating shaft and all the brushes on its surface need to be replaced, resulting in waste.

[0004] Therefore, the problem that this utility model urgently needs to solve is to provide a guardrail cleaning vehicle roller brush device that allows for the selection of appropriate replacement methods based on the wear area of ​​the brush body during use, enabling both overall replacement of the roller brush assembly and partial replacement of the brush body, thereby reducing maintenance costs. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue that in the existing technology, the tumbler assembly is a single piece, with the brush and shaft integrally formed. If some brushes are damaged, the entire shaft and all brushes on its surface need to be replaced, resulting in waste. This utility model provides a tumbler device for guardrail cleaning vehicles that allows for selection of replacement methods based on the wear area of ​​the brush body. It enables both complete replacement of the brush body and partial replacement of the brush body, reducing maintenance costs.

[0006] To achieve the above objectives, this utility model provides a roller brush device for a guardrail cleaning vehicle, including a bracket mounted on the cleaning vehicle and two sets of roller brush assemblies that are spaced apart and vertically rotatably mounted on the bracket. Each set of roller brush assemblies includes: a rotating shaft that is vertically and rotatably mounted on the bracket; a cylinder that is coaxially and detachably mounted on the rotating shaft via a first fixing component and can rotate with it; a number of mounting plates that are detachably mounted on the surface of the cylinder at equal intervals along the circumferential direction; and a number of bundles of flexible brushes that are uniformly fixed on each mounting plate.

[0007] Preferably, the first fixing component includes: a first limiting ring, a screw, a second limiting ring, and a nut; wherein, At least one flat key is vertically fixed on the rotating shaft. The upper part of the inner cavity of the cylinder is recessed inward to form a keyway that cooperates with the flat key. A first limiting ring is coaxially sleeved on the rotating shaft at the bottom end of the cylinder. At least one screw is vertically fixed on the upper end of the first limiting ring. A first through hole is vertically opened through the shaft of the cylinder for the screw to pass through. A second limiting ring is coaxially and fixedly sleeved on the rotating shaft at the upper end of the cylinder, abutting against the upper end of the cylinder. A second through hole is vertically opened through the upper end of the second limiting ring for the screw to pass through. The screw passes through the first through hole and the second through hole in sequence and extends to the top of the second limiting ring. A nut that can abut against the upper end of the second limiting ring is threaded on the screw.

[0008] Preferably, the inner wall portions of the first limiting ring and the second limiting ring are recessed inward to form a first clearance groove and a second clearance groove for the flat key to pass through.

[0009] Preferably, the surface of the cylinder is uniformly provided with receiving grooves for assembling all the assembly plates along its circumference. The upper and lower ends of each assembly plate are partially recessed to form a first limiting groove with a convex cross-section. The upper and lower ends of the cylinder are respectively provided with limiting channels that communicate with the two first limiting grooves of each assembly plate. The upper and lower ends of the cylinder away from the first limiting groove of each assembly plate are partially recessed to form a second limiting groove that communicates with the limiting channels and cooperates with the first limiting groove. Each limiting channel and the first and second limiting grooves that communicate with its upper and lower ends form an assembly cavity. A second fixing component can be detachably snapped into each assembly cavity.

[0010] Preferably, each of the second fixing components includes: a tensioning element, a shaped limiting plate, a crossbar, and a tension spring; wherein, Two parallel and vertical tensioning members are spaced apart and horizontally connected by an I-shaped crossbar that is slidably connected to the two tensioning members. Each crossbar between the two tensioning members is fitted with a tensioning spring. The upper and lower ends of the two tensioning members extend to the sides to abut against two irregularly shaped limiting plates that can abut against the first limiting groove and the second limiting groove.

[0011] Preferably, each of the second limiting grooves at the upper and lower ends of the cylinder has a portion of its periphery protruding upwards to form a protrusion, and a sealing cap is threadedly fixed to the outer wall of the protrusion.

[0012] According to the above technical solution, the beneficial effects of the guardrail cleaning vehicle roller brush device provided by this utility model in use are as follows: (1) During long-term use, the brushes on the roller brush assembly will wear out and need to be replaced to ensure that the brushes on the roller brush assembly can contact the guardrail and ensure its cleaning effect. The roller brush assembly provided in this application can adopt different replacement methods according to the size of the damaged area of ​​the brush body on the roller brush surface. The main replacement methods include the following two: (2) First replacement method: When a large area of ​​the brush body on the roller brush assembly is damaged and needs to be replaced, the cylinder can be removed from the rotating shaft to remove all the flexible brush bodies on the cylinder, and the new cylinder and flexible brush bodies can be assembled on the rotating shaft through the first fixing component.

[0013] (3) Second replacement method: When a part of the brush body on the roller brush assembly is damaged, only that part of the brush body needs to be replaced. During replacement, the corresponding mounting plate is removed from the cylinder to remove the corresponding damaged flexible brush body on its surface, and a new mounting plate and a new flexible brush body are installed on the cylinder to achieve the function of partial replacement. The advantage of using partial replacement is that there is no need to replace other flexible brush bodies on the cylinder, which saves on usage costs compared to existing roller brush assemblies. Because the existing roller brush assembly is an integral unit, with the brush and the rotating shaft molded as one piece, if some brushes are damaged, the entire rotating shaft of the roller brush assembly and the brushes on its surface need to be replaced, resulting in waste.

[0014] In summary, the tumble brush assembly provided by this utility model is detachable, and the appropriate replacement method can be selected according to the wear area of ​​the brush body. It can replace the entire brush body of the tumble brush assembly or replace only part of the brush body, thus reducing maintenance costs.

[0015] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] like Figure 1-7As shown, the present invention provides a roller brush device for a guardrail cleaning vehicle, including a bracket 5 mounted on the cleaning vehicle and two sets of roller brush assemblies that are spaced apart and vertically rotatably mounted on the bracket 5. Each set of roller brush assemblies includes: a rotating shaft 101 that is vertically and rotatably mounted on the bracket 5; a cylinder 102 that is coaxially and detachably mounted on the rotating shaft 101 via a first fixing component 2 and can rotate with it; a plurality of mounting plates 103 that are detachably mounted on the surface of the cylinder 102 at equal intervals along the circumferential direction; and a plurality of bundles of flexible brushes 104 that are uniformly fixed on each mounting plate 103.

[0020] In the above scheme, the rotation of the rotating shaft 101 of each tumbling assembly is powered by a servo motor mounted on the bracket 5, which drives the rotation.

[0021] In the above-mentioned solutions, the brushes on the tumbler assembly wear down over long-term use and need to be replaced to ensure that the brushes on the tumbler assembly can still contact the guardrail and maintain its cleaning effect. The tumbler assembly provided in this application allows for different replacement methods depending on the size of the damaged area of ​​the brush body on the tumbler surface. The main replacement methods include the following two: The first replacement method: When a large area of ​​the brush body on the roller brush assembly is damaged and needs to be replaced, the cylinder 102 can be removed from the rotating shaft 101 to remove all the flexible brush bodies 104 on the cylinder 102, and the new cylinder 102 and flexible brush bodies 104 can be assembled on the rotating shaft 101 through the first fixing component 2.

[0022] The second replacement method: When a portion of the brush on the roller brush assembly is damaged, only that portion of the brush needs to be replaced. During replacement, the corresponding mounting plate 103 is removed from the cylinder 102 to remove the damaged flexible brush 104 from its surface. A new mounting plate 103 and a new flexible brush 104 are then installed on the cylinder 102, achieving partial replacement. The advantage of this partial replacement method is that it eliminates the need to replace other flexible brushes 104 on the cylinder 102, saving on operating costs compared to existing roller brush assemblies. This is because existing roller brush assemblies are one-piece, with the brush and shaft molded as a single unit. If only part of the brush is damaged, the entire roller brush assembly's shaft and all the brushes on its surface need to be replaced, resulting in waste.

[0023] In summary, the tumble brush assembly provided by this utility model is detachable. The appropriate replacement method can be selected according to the wear area of ​​the brush body. It can replace the entire brush body of the tumble brush assembly or replace only a part of the brush body, thus reducing maintenance costs.

[0024] In a preferred embodiment of this utility model, the first fixing component 2 includes: a first limiting ring 201, a screw 202, a second limiting ring 203, and a nut 204; wherein, At least one flat key 4 is vertically fixed on the rotating shaft 101. The upper part of the inner cavity of the cylinder 102 is recessed inward to form a keyway that mates with the flat key 4. A first limiting ring 201 is coaxially sleeved on the rotating shaft 101 at the bottom end of the cylinder 102. At least one screw 202 is vertically fixed on the upper end of the first limiting ring 201, and a first through hole is vertically opened on the shaft of the cylinder 102 for the screw 202 to pass through. A second limiting ring 203 is coaxially and fixedly sleeved on the rotating shaft 101 at the upper end of the cylinder 102, abutting against the upper end of the cylinder 102. The upper end of the second limiting ring 203 has a second through hole for the screw 202 to pass through. The screw 202 passes through the first through hole and the second through hole in sequence and extends to the top of the second limiting ring 203. A nut 204 that can abut against the upper end of the second limiting ring 203 is threadedly fixed on the screw 202.

[0025] In the above scheme, during assembly, following a bottom-to-top sequence, first, the cylinder 102 is coaxially assembled onto the rotating shaft 101 and abuts against the second limiting ring 203. Then, the screw 202 on the first limiting ring 201 is sequentially passed through the first and second through holes on the cylinder 102 and the second limiting ring 203, and the first limiting ring 201 is abutted against the bottom end of the cylinder 102, so that the top end of the screw 202 extends from the second limiting ring 203. The second through hole of the limiting ring 203 is passed through, and the nut 204 is screwed from the top of the screw 202 onto its shaft until the nut 204 abuts against the second limiting ring 203. Thus, the cylinder 102 is coaxially assembled onto the rotating shaft 101 through the first fixing component 2. With the cooperation of the flat key 5 on the rotating shaft 101 and the keyway on the cylinder 102, the cylinder 102 assembled on the rotating shaft 101 can rotate together.

[0026] In addition, there can be multiple screws 202, which can be vertically fixed at equal intervals at their upper ends along the circumference of the first limiting ring 201. This improves the stability and reliability of the cylinder 102 assembled on the rotating shaft 101.

[0027] In a preferred embodiment of this utility model, the inner wall portions of the first limiting ring 201 and the second limiting ring 203 are recessed inward to form a first clearance groove and a second clearance groove for the flat key 4 to pass through.

[0028] In a preferred embodiment of this utility model, the surface of the cylinder 102 is uniformly provided with receiving grooves for assembling all the assembly plates 103 along its circumferential direction. The upper and lower ends of each assembly plate 103 are partially recessed to form a first limiting groove with a convex cross-section. The upper and lower ends of the cylinder 102 are respectively provided with limiting channels communicating with the two first limiting grooves of each assembly plate 103. The upper and lower ends of the cylinder 102 away from the first limiting groove of each assembly plate 103 are partially recessed to form a second limiting groove communicating with the limiting channels and cooperating with the first limiting groove. Each limiting channel and the first and second limiting grooves communicating with its upper and lower ends form an assembly cavity, and a second fixing component 3 can be detachably snapped into each assembly cavity.

[0029] In the above scheme, such as Figure 2 and 3 As shown, the assembly cavity, composed of the first limiting groove, the second limiting groove, and the limiting channel, and the fixing component 3 work together to achieve a quick-release function, allowing the assembly plate 103 to be quickly fixed to or removed from the cylinder 102. This improves assembly efficiency.

[0030] In a preferred embodiment of this utility model, each of the second fixing components 3 includes: a tensioning member 301, a shaped limiting plate 302, a crossbar 303, and a tension spring 304; wherein, Two parallel and vertical tensioning members 301 are spaced apart and horizontally connected by a crossbar 303 in the shape of an I-beam and slidably connected to the two tensioning members 301. Each crossbar 303 located between the two tensioning members 301 is fitted with a tensioning spring 304. The upper and lower ends of the two tensioning members 301 extend to the sides to abut against two irregularly shaped limiting plates 302 in the first limiting groove and the second limiting groove, respectively.

[0031] In the above scheme, during use, the two tensioning members 301 of the second fixing component 3 are pressed together by hand to compress the multiple tensioning springs 304 between them so that they are in a compressed state, so that the distance between the two tensioning members 301 is less than the width of the limiting channel and the first or second limiting groove, so that the second fixing component 3 can be inserted into the assembly cavity. When the two irregular limiting plates 302 at the ends of the two tensioning members 301 are inserted into the corresponding first limiting groove of the assembly plate 103, the hand is released so that the two tensioning members 301 move away from each other under the action of the tensioning springs 304, so that the irregular limiting plates 302 at the upper and lower ends of the two tensioning members 301 can abut against the first and second limiting grooves of the assembly plate 103 and the cylinder 102 respectively, thereby enabling the assembly work to be completed quickly.

[0032] When disassembly or replacement is required, simply bring the two tensioning members 301 close together until the two irregularly shaped limiting plates 303 at their respective ends also move close together until the distance between them is less than the width of the limiting channel. Then, pull the second fixing component 3 out from the second limiting groove at the end of the cylinder 102. Subsequently, the corresponding mounting plate 103 can be removed from the receiving groove of the cylinder 102. This achieves a quick-release function, facilitating the replacement of the flexible brush body 104 on the mounting plate 103.

[0033] Of course, each assembly plate 103 can also be fixed with screws instead of the second fixing component 3. Each assembly plate 103 has two vertically formed threaded blind holes at its upper and lower ends. The upper and lower ends of the cylinder 102 each have through holes corresponding to the two threaded blind holes at each end of the assembly plate 103, allowing the screws to pass through. During assembly, each assembly plate 103 is inserted into the receiving groove on the cylinder 102, and two screws are passed through the two through holes at the upper and lower ends of the cylinder 102 and screwed into the two threaded blind holes at the upper and lower ends of the assembly plate 103, thereby assembling each assembly plate 103 onto the cylinder 102. This facilitates the replacement of the flexible brush body 104 on the assembly plate 103.

[0034] In a preferred embodiment of this utility model, each of the second limiting grooves at the upper and lower ends of the cylinder 102 has a portion of its periphery protruding upwards to form a protrusion, and a sealing cap is threadedly fixed to the outer wall of the protrusion.

[0035] In the above solution, on the one hand, it serves the functions of dust prevention and waterproofing, preventing dust and water droplets from entering the assembly cavity and corroding the second fixing component 3 during the cleaning process of the guardrail, when the cleaning vehicle sprays water and sweeps the guardrail.

[0036] In summary, the roller brush device for guardrail cleaning vehicles provided by this utility model overcomes the problem that in the prior art, the roller brush assembly is an integral piece, with the brush and the rotating shaft molded as one piece. If some brushes are damaged, the entire rotating shaft and the brushes on its surface of the roller brush assembly need to be replaced, resulting in waste.

[0037] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0039] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
