Description

Technical Field

[0001] The utility model relates to the technical field of road cleaning, in particular to an adjustable road cleaning device. Background Art

[0002] Road sweeping devices are usually installed on sweeping vehicles or mechanical equipment and are used to clean and maintain road surfaces.

[0003] In the related art, the road cleaning device usually hinges the brackets where the two sets of cleaning brushes are located on both sides of the bottom of the cleaning vehicle, and tilts the brackets up or down through an adjustment device (for example, one end of the driving cylinder is hinged to the bottom of the cleaning vehicle, and the other end is hinged to the bracket. When the driving cylinder stroke changes, the bracket rotates along the hinge), so that the mounting frame rotates along the hinge, and the cleaning brushes are separated from or contacted with the ground, realizing a non-working or working state.

[0004] However, in order to increase the road cleaning width, a longer bracket is usually installed, and a plurality of cleaning brushes working synchronously are installed on the bracket. Due to the extension of the bracket, the above-mentioned lifting method will cause the end of the bracket away from the hinge to be lifted to a greater height, which will interfere with the bottom of the vehicle, and the cleaning width of the existing road cleaning device cannot be adjusted according to the width of the road. For example, the lane width of the branch road in the city is usually between 2.5 meters and 3.0 meters, while the lane width of the main road is 3.0 meters to 3.7 meters. When cleaning roads of different widths, it is usually necessary to use cleaning vehicles equipped with brackets of different specifications, which makes the adaptability of existing cleaning vehicles low.

[0005] In addition, when the road surface is actually being cleaned, the high-speed rotation of the cleaning brush can easily cause gravel on the ground to fly out, posing a safety hazard to pedestrians or vehicles. Summary of the invention

[0006] The utility model aims to solve one of the technical problems in the above-mentioned technology at least to a certain extent.

[0007] To achieve the above-mentioned purpose, the first aspect of the utility model proposes an adjustable road cleaning device, comprising: a mounting frame, a driving cylinder, a mounting frame, a transmission device, a cleaning device and a shielding plate, wherein the two mounting frames are respectively mounted on both sides of the bottom of the cleaning vehicle; the two driving cylinders are respectively vertically arranged on the two mounting frames; the mounting frame is arranged below the mounting frame, and the two ends of the mounting frame are respectively connected to the telescopic ends of the two driving cylinders; the two groups of cleaning devices are respectively rotatably arranged at the bottom of the mounting frame; the transmission device is arranged on the mounting frame, and the two transmission ends of the transmission device are respectively connected to the rotating ends of the two groups of cleaning devices, so that the two groups of cleaning devices can rotate relative to or opposite to each other; the two shielding plates are respectively arranged on the outsides of the two groups of cleaning devices.

[0008] In addition, the adjustable road cleaning device proposed in the utility model may also have the following additional technical features:

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The adjustable road cleaning device according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the adjustable road cleaning device of the embodiment of the utility model may include a mounting frame 100, a driving cylinder 200, a mounting frame 300, a transmission device 400, a cleaning device 500 and a shielding plate 600.

[0027] The two mounting frames 100 are respectively mounted on both sides of the bottom of the cleaning vehicle.

[0028] It should be noted that a mounting hole is provided on the mounting frame 100, and relevant staff can install the mounting frame 100 on the bottom of the cleaning vehicle by tightening the bolts.

[0029] The two driving cylinders 200 are respectively vertically arranged on the two mounting frames 100 , the mounting frame 300 is arranged below the mounting frames 100 , and both ends of the mounting frame 300 are respectively connected to the telescopic ends of the two driving cylinders 200 .

[0030] It should be noted that, by controlling the two driving cylinders 200 , the height position of the mounting frame 300 can be changed following the telescopic stroke of the driving cylinders 200 .

[0031] The two groups of cleaning devices 500 are rotatably arranged at the bottom of the installation frame 300, and the transmission device 400 is arranged on the installation frame 300, and the two transmission ends of the transmission device 400 are respectively connected to the rotating ends of the two groups of cleaning devices 500, so that the two groups of cleaning devices 500 rotate relative to or opposite to each other.

[0032] It is understandable that, by starting the transmission device 400, the relevant staff can make the two groups of cleaning devices 500 rotate relative to or away from each other, thereby changing the unfolded width of the two groups of cleaning devices 500 to meet the needs of different cleaning widths.

[0033] The two shielding plates 600 are respectively arranged on the outer sides of the two groups of cleaning devices 500 .

[0034] It should be noted that the bottom position of the shielding plate 600 is higher than the bottom position of the cleaning device 500. While shielding the flying gravel, it can ensure that the cleaning device 500 can sweep the dust or debris on the road to both sides.

[0035] Specifically, after the relevant staff installs the mounting frame 100 on the bottom of the cleaning vehicle, the relevant staff can first control the contraction of the telescopic end of the driving cylinder 200, and then the mounting frame 300 drives the transmission device 400 and the cleaning device 500 to move upward, so that the cleaning device 500 is separated from the ground, and the relevant staff can drive the cleaning vehicle to the road to be cleaned.

[0036] When it is necessary to clean the road, the relevant staff controls the driving cylinder 200 to extend until the cleaning end of the cleaning device 500 contacts the ground, and then the relevant staff turns on the cleaning device 500 to clean the road.

[0037] When it is necessary to clean roads of different cleaning widths, the relevant staff can turn on the transmission device 400, and the transmission device 400 drives the two cleaning devices 500 to rotate toward or away from each other until the required width is reached. The relevant staff can drive the cleaning vehicle to continue cleaning the road.

[0038] In one embodiment of the present invention, Figure 4 As shown, the transmission device 400 includes a first driving motor 410 , two gears 420 and two sets of first transmission structures 430 .

[0039] Among them, the first drive motor 410 is set on the installation frame 300, and the two gears 420 are respectively meshed and rotatably set in the installation frame 300. One of the gears 420 is connected to the output end of the first drive motor 410, and the two gears 420 are respectively connected to the rotating end of the corresponding cleaning device 500 through the first transmission structure 430.

[0040] It should be noted that after the relevant staff starts the first drive motor 410, the first drive motor 410 drives the gear 420 connected thereto to rotate, and the two gears 420 are meshed and connected and rotate in opposite directions. The two first transmission structures 430 respectively transmit power to the rotating ends of the two cleaning devices 500 through the gears 420 connected thereto, thereby causing the two cleaning devices 500 to rotate relative to or away from each other.

[0041] To clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 5 As shown, each cleaning device 500 includes a rotating arm 510 , a second driving motor 520 , a cleaning brush 530 and a second transmission structure 540 .

[0042] Among them, the rotating arm 510 can be rotatably set at the bottom of the installation frame 300, and multiple cleaning brushes 530 can be rotatably set on the rotating arm 510 in turn. Two adjacent cleaning brushes 530 are connected through the second transmission structure 540 respectively, and the output end of the second drive motor 520 is connected to the rotating shaft of one of the cleaning brushes 530.

[0043] It should be noted that when the cleaning device 500 is started, the relevant staff starts the second drive motor 520, and the second drive motor 520 drives the cleaning brush 530 connected thereto, and the other cleaning brushes 530 rotate synchronously through the second transmission structure 540 connected thereto, so as to realize the synchronous operation of all the cleaning brushes 530 on the rotating arm 510.

[0044] To clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 4 and Figure 5 As shown, the first transmission structure 430 and the second transmission structure 540 both include a first rotating wheel 431 , a second rotating wheel 432 and a synchronous belt 433 .

[0045] The synchronous belt 433 connects the first rotating wheel 431 and the second rotating wheel 432 respectively.

[0046] The first rotating wheel 431 in the first transmission structure 430 is coaxially connected to the corresponding gear 420 ; the second rotating wheel 432 in the first transmission structure 430 is coaxially connected to the corresponding rotating arm 510 .

[0047] It should be noted that when the first transmission structure 430 is working, the corresponding gear 420 rotates to drive the first rotating wheel 431 to rotate, and the second rotating wheel 432 can be rotated through the transmission effect of the synchronous belt 433, so that the rotating arm 510 rotates following the second rotating wheel 432.

[0048] The first rotating wheel 431 and the second rotating wheel 432 in the second transmission structure 540 are coaxially connected to two adjacent cleaning brushes 530 respectively.

[0049] In one embodiment of the present invention, the shielding plate 600 is a folding plate, and one side of the shielding plate 600 is connected to the rotating arm 510, and the other side is inclined downward and extends outward.

[0050] As a possible situation, a symmetrical shielding plate 600 may be provided on the inner side of the rotating arm 510 to prevent gravel from flying to the bottom of the vehicle and causing damage to the bottom of the vehicle.

[0051] In one embodiment of the utility model, the adjustable road cleaning device 500 also includes a controller, and the two driving cylinders 200, the transmission device 400 (i.e., the first driving motor 410), and the two groups of cleaning devices 500 (i.e., the second driving motor 520) are respectively connected to the controller; wherein, the two driving cylinders 200 are respectively connected to the controller synchronously.

[0052] It should be noted that the controller can be connected to the control switch, and the control switch can be installed in the cab of the cleaning vehicle. Relevant staff can operate the control switch in the cab, so that the controller can control the drive cylinder 200, the first drive motor 410 and the second drive motor 520 respectively.

[0053] In summary, according to the adjustable road cleaning device 500 of the embodiment of the utility model, the transmission device 400 can synchronously drive the cleaning devices 500 on both sides closer to or away from each other, so as to adjust different cleaning widths. The vertical lifting of the mounting frame 300 by the vertically arranged driving cylinder 200 can avoid interference between the entire device and the bottom of the vehicle. In addition, by arranging a baffle 600 on the outer side of the cleaning device 500, it can effectively prevent gravel from flying out, thereby reducing the safety hazard to pedestrians and other vehicles.
