Description

Technical Field

[0001] This invention specifically relates to a cleaning device for road guardrails. Background Technology

[0002] Highway guardrails are strip-shaped protective energy-absorbing structures installed on the outer side of the driving lane or in the central median strip of a highway. When an accident vehicle collides with the guardrail, it absorbs and guides the collision energy through blocking, deformation of the guardrail itself, or vehicle climbing, thereby stopping the vehicle and reducing the degree of injury to the driver and passengers. However, due to severe road pollution, guardrails accumulate a large amount of dust and stains after prolonged use, which accelerates corrosion and affects road cleanliness. Therefore, regular cleaning of the guardrails is necessary.

[0003] For example, Chinese invention patent No. 201911292525.6 provides a two-way guardrail cleaning vehicle. This invention can not only clean both sides of the guardrail, but also, because it is done by flipping, the flipping process does not occupy the space in front and behind the vehicle frame, so the requirements for installation space are not high. Moreover, since both sides of the guardrail use the cleaning device, the structure is simpler and the cost is reduced.

[0004] However, the height of guardrails varies on different roads, and existing guardrail cleaning devices are not convenient for thoroughly cleaning guardrails of different heights from multiple angles, thus limiting their usability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a road guardrail cleaning device to solve the technical problem mentioned in the background art that existing guardrail cleaning devices are inconvenient for thoroughly cleaning guardrails of different heights from multiple angles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a road guardrail cleaning device, comprising:

[0007] The frame is height-adjustable and mounted on the construction vehicle;

[0008] Multiple sets of mounting plates are arranged longitudinally, one set of which is fixedly connected to the frame, and each set of mounting plates is equipped with a sprayer that is mounted via a mounting shaft;

[0009] A fixing mechanism is connected to the ends of the multiple sets of sprayers to keep them parallel when the multiple sets of sprayers are driven to move.

[0010] An extension mechanism is mounted on the frame and connected to multiple sets of mounting plates to drive the multiple sets of mounting plates to open and close longitudinally at equal intervals;

[0011] A drive mechanism, mounted on the frame and connected to one of the sprayers, drives the sprayers to reciprocate along the mounting axis.

[0012] Furthermore, the fixing mechanism includes:

[0013] The connecting ring has the same number of sets as the sprayers, and is rotatably connected to multiple sets of the sprayers respectively;

[0014] The mounting rod is hollow and passes through multiple sets of connecting rings, and is fixedly connected to the bottom set of connecting rings.

[0015] A movable rod, slidably disposed within the mounting rod, has multiple sets of locking blocks spaced at intervals along its axis, and a connecting ring is engaged between two sets of these locking blocks; and

[0016] An elastic element is disposed inside the mounting rod, and one end of the elastic element abuts against the movable rod.

[0017] Furthermore, the mounting rod is provided with a first handle, and the movable rod is provided with a second handle, the second handle being slidably disposed within the first handle.

[0018] Furthermore, the topmost set of mounting plates is provided with a first positioning frame, and the bottommost set of mounting plates is provided with a second positioning frame. The second positioning frame is slidably mounted on the first positioning frame, and the ends of the remaining sets of mounting plates are liftably sleeved on the first positioning frame or the second positioning frame.

[0019] Furthermore, the extension mechanism includes:

[0020] A first screw, one end of which is rotatably mounted on the frame, has its threaded end screwed to one of the sets of mounting plates; and

[0021] A connecting component is connected to multiple sets of mounting plates, wherein one set of mounting plates drives multiple sets of mounting plates to open and close at equal intervals during the lifting and lowering process.

[0022] Furthermore, the connecting assembly includes multiple sets of connecting frames, which are respectively hinged to multiple sets of mounting plates, with one end of each pair of adjacent connecting frames hinged together.

[0023] Furthermore, the drive mechanism includes:

[0024] A first sliding frame is disposed on one of the groups of sprayers;

[0025] The first drive column is slidably mounted in the first slide frame, and a connecting rod is provided on the first drive column;

[0026] An adjustment component is mounted on the frame and connected to the first screw and the connecting rod. During the rotation of the first screw, the adjustment component drives the connecting rod to slide laterally.

[0027] A lifting assembly is mounted on the frame and connected to the connecting rod to drive the connecting rod to reciprocate up and down.

[0028] Furthermore, the adjustment component includes:

[0029] The second screw is rotatably mounted on the frame along its axis;

[0030] A slider is sleeved on and screwed to the second screw, and the connecting rod is vertically and retractably threaded through the slider;

[0031] A first bevel gear is mounted on the first screw; and

[0032] The second bevel gear is mounted on the second screw and meshes with the first bevel gear.

[0033] Furthermore, the lifting assembly includes:

[0034] A lifting rod is mounted on the frame in a height-adjustable manner, and a connecting rod is slidably mounted on the lifting rod;

[0035] The second sliding frame is mounted on the lifting rod; and

[0036] A drive motor is fixedly mounted on the frame, and the output shaft of the drive motor is provided with an eccentric second drive column, which is slidably engaged in the second slide frame.

[0037] Furthermore, a cleaning brush is provided at the end of the sprayer.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. When in use, this device can drive one set of sprayers to swing back and forth along the mounting shaft via a drive mechanism to spray the guardrail. During the movement of one set of sprayers, a fixing mechanism keeps multiple sets of sprayers parallel at all times. Thus, the movement of one set of sprayers drives the synchronous movement of multiple sets of sprayers, providing a comprehensive spray and wash of the guardrail. When the height of the guardrail increases, the entire device can be raised a certain distance, and then the extension mechanism drives multiple sets of mounting plates to open and close longitudinally at equal intervals, thereby increasing the spacing between the multiple sets of sprayers. This allows for spraying guardrails of different heights, and ensures that when spraying higher guardrails, multiple sets of sprayers can swing back and forth, resulting in a more comprehensive and thorough cleaning of the guardrail.

[0040] 2. The first screw can be rotated to raise and lower one set of mounting plates. During the raising and lowering process, the connecting components drive multiple sets of mounting plates to open and close at equal intervals, thereby enabling multiple sets of sprinklers to open and close at equal intervals. During the rotation of the first screw, the meshing of the first and second bevel gears drives the second screw to rotate. During the rotation of the second screw, the slider slides, thereby causing the connecting rod to move laterally and the first drive column to move laterally. During the reciprocating raising and lowering process of the connecting rod controlled by the lifting components, the larger the distance between the connecting rod and the mounting shaft, the smaller the swing amplitude of the sprinkler. This allows multiple sets of sprinklers to swing more significantly after the distance is increased, making the cleaning of the guardrail more comprehensive and efficient, improving water utilization, and effectively reducing cleaning dead corners.

[0058] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0059] Example:

[0060] like Figure 1 , 2 As shown, the present invention provides a road guardrail cleaning device, including a liftable frame 101 mounted on a construction vehicle. Multiple sets of mounting plates 201 are arranged longitudinally on the frame 101, one set of mounting plates 201 is fixedly connected to the frame 101, and each set of mounting plates 201 is provided with a sprayer 301 mounted through a mounting shaft 303. A cleaning brush 302 is provided at the end of the sprayer 301.

[0061] The frame 101 can be mounted on a construction vehicle via a hydraulic or electric telescopic rod, or it can be raised and lowered on the construction vehicle via a screw drive. By controlling the raising and lowering of the frame 101, the device can be easily installed on the guardrail for cleaning. Multiple sprayers 301 are connected to a water pump via pipes, which supplies water to the sprayers 301 to clean the guardrail. Each sprayer 301 can swing along the mounting shaft 303 to spray the guardrail from multiple directions. Simultaneously, cleaning brushes 302 scrub the guardrail, reducing blind spots and improving cleaning effectiveness.

[0062] like Figure 3 , 4As shown, in this embodiment, the frame 101 is provided with an extension mechanism connected to multiple sets of mounting plates 201. The extension mechanism drives the multiple sets of mounting plates 201 to open and close longitudinally at equal intervals. The extension mechanism includes a first screw 501 and a connecting assembly. One end of the first screw 501 is rotatably mounted on the frame 101, and its threaded end is screwed to one of the sets of mounting plates 201. The connecting assembly includes multiple sets of connecting brackets 204, which are respectively hinged to the multiple sets of mounting plates 201. One end of each pair of adjacent connecting brackets 204 is hinged together.

[0063] The first screw 501 can be rotated to move one set of mounting plates 201 up and down within the frame 101. This allows the first screw 501 to be screwed to the second set of mounting plates 201 from the top down. The rotation of the first screw 501 causes a change in the distance between the second set of mounting plates 201 and the uppermost set of mounting plates 201, thereby causing the two sets of connecting frames 204 connected to it to rotate relative to each other. Through the cooperation of multiple sets of connecting frames 204, multiple sets of mounting plates 201 can be raised and lowered, and the distance between multiple sets of mounting plates 201 is equal, so as to realize the equal-spaced deployment and retraction of multiple sets of sprayers 301, which facilitates uniform washing of the guardrail.

[0064] Furthermore, a first positioning frame 202 is provided on the topmost set of mounting plates 201, and a second positioning frame 203 is provided on the bottommost set of mounting plates 201. The second positioning frame 203 is slidably mounted on the first positioning frame 202. The ends of the remaining sets of mounting plates 201 are lifted and lowered and sleeved on the first positioning frame 202 or the second positioning frame 203. The first positioning frame 202 and the second positioning frame 203 cooperate to position the movement of multiple sets of mounting plates 201, thereby enabling multiple sets of mounting plates 201 to rise and fall stably, improving the stability of the device.

[0065] like Figures 3 to 6 As shown, in this embodiment, the ends of multiple sets of sprayers 301 are connected by a fixing mechanism. When the multiple sets of sprayers 301 are driven to move by the fixing mechanism, they remain parallel. The fixing mechanism includes multiple sets of connecting rings 304, which are rotatably connected to the multiple sets of sprayers 301 respectively. It also includes a hollow mounting rod 401, which passes through the multiple sets of connecting rings 304 and is fixedly connected to the bottom set of connecting rings 304. A movable rod 403 is slidably arranged inside the mounting rod 401. Multiple sets of locking blocks 404 are arranged at intervals along the axis of the movable rod 403. The connecting ring 304 is locked between two sets of locking blocks 404. An elastic element 406 is provided between the inner wall of the mounting rod 401 and the movable rod 403.

[0066] In the initial state, the engagement of the locking block 404 on the movable rod 403 with the connecting ring 304 ensures that multiple sprayers 301 are in a parallel state. This allows one set of sprayers 301 to swing synchronously along the mounting shaft 303 via a fixing mechanism, driving the other sets of sprayers 301 to swing synchronously. A first handle 402 is provided on the mounting rod 401, and a second handle 405 is provided on the movable rod 403. The second handle 405 is laterally slidable within the first handle 402. When the spacing of multiple sprayers 301 needs to be adjusted, the first handle 402 and the second handle 405 can be squeezed and closed, causing the movable rod 403 to slide laterally within the mounting rod 401 and compressing the elastic element 406. This causes the locking blocks 404 to retract, releasing the fixing of the connecting ring 304, thus allowing adjustment of the sprayer spacing. After adjustment, release the first handle 402 and the second handle 405. Under the reset capability of the elastic element 406, the movable rod 403 is reset, thereby causing the locking block 404 to extend so that multiple sets of connecting rings 304 can be locked between two sets of locking blocks 404 again, so as to ensure that multiple sets of sprayers 301 swing synchronously.

[0067] like Figure 2 , 7 As shown in Figure 8, in this embodiment, a drive mechanism connected to one of the sprayers 301 is provided on the frame 101. The drive mechanism drives the sprayers 301 to reciprocate along the mounting shaft 303. The drive mechanism includes a first sliding frame 305 disposed on one of the sprayers 301. A first drive column 702 is slidably engaged in the first sliding frame 305, and a connecting rod 701 is provided on the first drive column 702. An adjustment assembly connected to the first screw 501 and the connecting rod 701 is provided on the frame 101. During the rotation of the first screw 501, the adjustment assembly drives the connecting rod 701 to slide laterally. The adjustment assembly includes a second screw 704 rotatably mounted on the frame 101 along its axis. A slider 703 is screwed onto the second screw 704. The connecting rod 701 is vertically mounted on the slider 703. A first bevel gear 502 is provided on the first screw 501, and a second bevel gear 705 is provided on the second screw 704. The second bevel gear 705 meshes with the first bevel gear 502.

[0068] During the process of rotating the first screw 501 to unfold the multiple sets of mounting plates 201 at equal intervals, the second screw 704 is driven to rotate through the meshing of the second bevel gear 705 and the first bevel gear 502. During the rotation of the second screw 704, the slider 703 is driven to slide along the axis of the second screw 704, thereby causing the first drive column 702 to move in the first slide frame 305 towards the mounting shaft 303. This allows the multiple sets of sprinklers 301 to swing within a wide range by controlling the lifting and lowering of the connecting rod 701 and the first drive column 702 when the spacing between the multiple sets of sprinklers 301 is large, so as to spray the higher guardrails comprehensively.

[0069] Similarly, during the process of retracting multiple sets of mounting plates 201 at equal intervals by rotating the first screw 501 in the opposite direction, the first drive column 702 is driven to move away from the mounting shaft 303 within the first slide frame 305. This allows the multiple sets of sprayers 301 to swing within a small range when the spacing between them is small, by controlling the lifting and lowering of the connecting rod 701 and the first drive column 702. This makes the spraying of the guardrail more concentrated when cleaning lower guardrails, thus improving water utilization.

[0070] like Figure 2 , 7 As shown in Figure 8, in this embodiment, the driving mechanism further includes a lifting assembly mounted on the frame 101 and connected to the connecting rod 701, which drives the connecting rod 701 to reciprocate up and down. The lifting assembly includes a lifting rod 601 mounted on the frame 101 that can be lifted and lowered, and the connecting rod 701 is slidably mounted on the lifting rod 601. A second sliding frame 602 is mounted on the lifting rod 601, and a drive motor 603 is fixedly mounted on the frame 101. The output shaft of the drive motor 603 is provided with an eccentric second drive column 604, which is slidably engaged within the second sliding frame 602.

[0071] During the driving process, the drive motor 603 drives the second drive column 604 to move circumferentially along the output shaft of the drive motor 603. Thus, through the cooperation of the second drive column 604 and the second slide frame 602, the lifting rod 601 is driven to move up and down repeatedly, thereby driving the connecting rod 701 to move up and down repeatedly. The connecting rod 701 can also slide laterally on the lifting rod 601 to adapt to the position change of the slider 703.

[0072] Specific usage and beneficial effects of the present invention:

[0073] When in use, the device can drive the second drive column 604 to move circumferentially via the drive motor 603. This, in turn, drives the lifting rod 601 to move up and down repeatedly via the cooperation of the second drive column 604 and the second sliding frame 602. During the lifting process, the lifting rod 601 drives the first drive column 702 to move up and down repeatedly via the connecting rod 701. This, in turn, drives one set of sprayers 301 to swing back and forth along the mounting shaft 303 via the cooperation of the first drive column 702 and the first sliding frame 305, thus spraying the guardrail in multiple directions. During the movement of one set of sprayers 301, the cooperation of the mounting rod 401, the movable rod 403, and the multiple sets of locking blocks 404 on the movable rod 403 ensures that the multiple sets of connecting rings 304 are in an equally spaced state. This keeps the multiple sets of sprayers 301 parallel, so that the movement of one set of sprayers 301 drives the synchronous movement of multiple sets of sprayers 301, providing a comprehensive spraying and washing of the guardrail.

[0074] When the height of the guardrail increases, the entire device can be lifted a certain distance, and the fixing components can be released from fixing the position of the connecting ring 304. Then, by rotating the first screw 501, one set of mounting plates 201 can be raised and lowered. During the raising and lowering process, the mounting plates 201 are driven to open and close longitudinally at equal intervals through the cooperation of multiple sets of connecting frames 204, thereby increasing the spacing between multiple sets of sprayers 301, so as to spray guardrails of different heights. It is also ensured that when spraying higher guardrails, multiple sets of sprayers 301 can swing back and forth, making the cleaning of the guardrail more comprehensive and thorough.

[0075] During the process of rotating the first screw 501 to drive multiple sets of mounting plates 201 to open and close at equal intervals, thereby enabling multiple sets of sprinklers 301 to open and close at equal intervals, the first screw 501, when rotating, drives the second screw 704 to rotate through the meshing of the first bevel gear 502 and the second bevel gear 705. During the rotation of the second screw 704, the slider 703 slides, thereby driving the connecting rod 701 to move laterally, which in turn drives the first drive column 702 to move laterally. During the process of controlling the reciprocating lifting and lowering of the connecting rod 701 through the lifting assembly, the larger the distance between the connecting rod 701 and the mounting shaft 303, the smaller the swing amplitude of the sprinkler 301. This allows the multiple sets of sprinklers 301 to swing more significantly after the distance is increased, making the cleaning of the guardrail more comprehensive and efficient, improving water utilization, and effectively reducing cleaning dead corners.

[0076] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
