DETAILED DESCRIPTION

[0035] In order to make those skilled in the art better understand the present invention, the present invention is further clearly and completely described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the features in the embodiments and examples of this application can be combined with each other.

[0036] A typical embodiment of the present invention provides a road guardrail cleaning device, such as Figure 1 As shown, it mainly includes a support plate 1, a slide plate 2, a slide frame 3, a first oil cylinder 5 and a second oil cylinder 6.

[0037] The support plate 1 is suspended on the frame of the walking device through a support arm, and the frame is a liftable frame. The slide plate 2 is installed on the side of the support plate 1 facing the guardrail to be cleaned, and the slide plate 2 can be displaced on the support plate 1 in the direction of travel of the walking device. The slide 3 is installed on the side of the slide plate 2 facing the guardrail to be cleaned, and the slide plate 3 can be displaced on the slide plate 2 in a direction perpendicular to the direction of travel of the walking device, and the slide 3 includes three transverse plate parts 4 for extending into the gap of the guardrail.

[0038] A brush roller is rotatably provided at the end of each transverse plate body 4, and the brush roller is used to be inserted into the gap of the guardrail to clean the side wall of the gap.

[0039] The fixed end of the first oil cylinder 5 is fixedly mounted on the support plate 1, and the movable end of the first oil cylinder 5 is fixedly connected to the slide plate 2. The first oil cylinder 5 is used to drive the slide plate 2 to move relative to the support plate 1. The fixed end of the second oil cylinder 6 is fixedly mounted on the slide plate 2, and the movable end of the second oil cylinder 6 is fixedly connected to the slide 3, and is used to drive the brush roller to insert or withdraw from the gap of the guardrail.

[0040] The walking device described in this embodiment is preferably a small cart with small size and light weight, which can be driven by manpower or electric power. The technical advantage of the present invention is to make up for the shortcomings of large guardrail cleaning equipment and achieve the purpose of further fine cleaning of guardrail gaps. It is particularly suitable for guardrail cleaning work in narrow road areas.

[0041] When the walking device moves, the brush roller is located outside the guardrail and contacts the surface of the guardrail. At this time, the brush roller moves forward with the walking device to clean the surface of the guardrail. The walking device stops moving and aligns the brush roller with the gap of the guardrail. At this time, the second oil cylinder 6 extends, and the movement of the carriage 3 allows the brush roller to be inserted into the gap of the guardrail to clean the side wall of the gap of the guardrail. In the case that the brush roller is not completely aligned with the gap of the guardrail, the length of the extension of the first oil cylinder 5 can be controlled to align the brush roller with the gap of the guardrail.

[0042] When the brush roller is inserted into the gap of the guardrail, due to the large width of the gap of the guardrail, the two sides of the brush roller may not touch the guardrail. By extending and retracting the first oil cylinder 5, the brush roller can be moved forward and backward, so that it can contact and clean the guardrail in turn. This makes the device suitable for guardrails with a variety of different gap widths.

[0043] In this embodiment, if Figure 1 , Figure 6 , Figure 7 , Fig.11 and Fig.12 As shown, the brush roller includes a roller body 7 and bristles 8 arranged on the surface of the roller body 7 , and a plurality of water squeezing plates 9 are arranged outside the roller body 7 .

[0044] In this embodiment, the squeezing plates 9 are preferably provided in four numbers and are distributed in a circular array around the axis of the roller body 7, and one end of the squeezing plates 9 is mounted on the transverse plate body 4. The squeezing plates 9 are used to cooperate with the roller body 7 to squeeze and dehydrate the bristles 8 passing through the inner surface of the squeezing plates 9. The four squeezing plates 9 form gaps in the front, rear, left and right directions respectively, and the bristles 8 can clean the side walls of the guardrail gap when passing through the left and right gaps.

[0045] Specifically, during the rotation of the brush roller, the bristles 8 will pass through each water squeezing plate 9 in turn. The bristles 8 will be squeezed when passing through the water squeezing plates 9, and the dirty water on the bristles 8 will be squeezed out, thereby improving the decontamination effect and the cleaning effect. At the same time, since a large amount of dirty water on the bristles 8 is squeezed out by the water squeezing plates 9, it can effectively prevent the dirty water from being thrown out when the bristles 8 rotates and causing repeated contamination of the guardrail, thereby further improving the cleaning effect of the guardrail.

[0046] In addition, in this embodiment, the radius of the outer circumference of the plurality of squeezing plates 9 is smaller than the distance between the roller body 7 and the side wall of the guardrail gap, so that the squeezing plates 9 will not affect the brush roller from being inserted into the guardrail gap.

[0047] like Figure 8 , Fig. 9 As shown, a spray cavity 10 is arranged in the roller body 7, and spray holes 11 are evenly arranged on the surface of the roller body 7. The spray cavity 10 is connected to a water diversion pipe 12, and the water diversion pipe 12 is used to connect to an external water supply device.

[0048] The water inlet pipe 12 introduces high-pressure water into the injection chamber 10. During the rotation of the roller body 7, the high-pressure water in the injection chamber 10 passes through the injection hole 11 and then sprays out of the roller body 7. At this time, the bristles 8 between the two water squeezing plates 9 are impacted by the sprayed water flow, and the water flow helps the bristles 8 to keep extending outward. In addition, the water flow will directly flush the guardrail, further improving the cleaning effect of the guardrail.

[0049] It should be noted that, for the side wall of the guardrail gap, during each rotation of the roller body 7, after the bristles 8 pass through any one of the two side walls of the guardrail gap, they are first dehydrated by a squeezing plate 9 to achieve primary decontamination. After that, the bristles 8 are separated from the squeezing plate 9 and enter the gap between the next squeezing plates 9. At this time, the squeezed bristles 8 are flushed and stretched by the water pressure, and the stains remaining inside the bristles 8 are flushed out again by the water flow, achieving secondary decontamination. During the secondary decontamination process, the direction in which the water flow flushes the bristles 8 is close to parallel to the side wall of the guardrail gap, which can reduce the stains generated by the secondary decontamination from being repeatedly flushed onto the side wall of the guardrail gap, further improving the cleaning effect of the guardrail. The bristles 8 that have been decontaminated twice will pass through a squeezing plate 9 for a third time, and the bristles 8 that have been decontaminated three times will then clean the other side wall of the guardrail gap.

[0050] In a relatively specific embodiment, the water pipe 12 is arranged inside the transverse plate body 4, such as Figure 6 , Figure 8 , Fig. 9 , Fig.10 As shown, the water diversion pipe 12 includes a ring sleeve 12.1 and a pipe body 12.2, the ring sleeve 12.1 is provided with a water diversion port 12.3, and one end of the pipe body 12.2 is connected to the water diversion port 12.3. The roller body 7 includes a connecting portion 7.1 penetrating the transverse plate body 4, the connecting portion 7.1 is provided with a plurality of water inlets 7.2 evenly distributed in a circumferential array, the ring sleeve 12.1 is rotatably sleeved on the outside of the connecting portion 7.1, and during the rotation process, the water inlets 7.2 and the water diversion port 12.3 can be sequentially connected.

[0051] According to this embodiment, the connecting part 7.1 rotatably mounts the roller body 7 on the transverse plate body 4. At the same time, the ring sleeve 12.1 is rotatably sleeved on the connecting part 7.1. The water inlet 7.2 is located within the range of the ring sleeve 12.1. During the rotation of the roller body 7, the connecting part 7.1 rotates synchronously with the roller body 7. At this time, there is always at least one water inlet 7.2 connected to the water inlet 12.3. The external water supply equipment introduces high-pressure water into the water inlet pipe 12. The water in the water inlet pipe 12 enters the injection chamber 10 through the water inlet 12.3 and the water inlet 7.2. The water flow quickly fills the injection chamber 10 and is ejected through the injection hole 11, thereby flushing the bristles 8 and the guardrail.

[0052] In a preferred embodiment, the axial length of the annular sleeve 12.1 is smaller than the axial length of the connecting portion 7.1. Figure 4 and 5 As shown, a synchronous belt assembly 13 sleeved on the outside of the connecting portion 7.1 is arranged in the carriage 3, and a rotating motor 14 for driving the synchronous belt assembly 13 to rotate is installed on the carriage 3.

[0053] Specifically, the portion of the connection part 7.1 where the ring sleeve 12.1 is sleeved and the portion of the connection part 7.1 where the synchronous belt assembly 13 is connected are distributed up and down in the axial direction of the connection part 7.1. The synchronous belt assembly 13 and the water diversion pipe 12 are both located in the transverse plate body 4, and the end of the water diversion pipe 12 away from the connection part 7.1 extends out from the transverse plate body 4 for connecting an external water supply hose.

[0054] In a preferred embodiment, the bristles 8 and the injection holes 11 are alternately distributed in the axial and circumferential directions of the roller body 7, and the end of the water squeezing plate 9 corresponding to the bristles 8 entering the gap between the water squeezing plate 9 and the roller body 7 is an inclined surface with an inner surface inclined outward.

[0055] Each bristle 8 is surrounded by four injection holes 11. The water jetted from the four injection holes 11 can flush the bristles 8 in all directions. Especially when the bristles 8 enter between the two water squeezing plates 9, the water flow can stretch the bristles 8 more quickly and quickly remove the stains adhering to the bristles 8.

[0056] like Figure 2 , Figure 3 As shown, in a preferred embodiment, the transverse plate body 4 includes a straight plate portion 4.1 and a circular portion 4.2 arranged at the front end of the straight plate portion 4.1, the roller body 7 is rotatably mounted on the circular portion 4.2 through its connecting portion 7.1, and four squeezing plates 9 are fixed on the circular portion 4.2 at intervals.

[0057] Specifically, a section of side wall is provided at the outer edge of the circular portion 4.2, the outer surface of the side wall of the circular portion 4.2 and the outer surface of the water squeezing plate 9 are located on the same circumference, the front side and both left and right sides of the upper surface of the circular portion 4.2 inside the side wall are provided with water collecting grooves 15, and the side wall of the circular portion 4.2 is provided with drainage ports 16 communicating with opposite ends of two adjacent drainage grooves 15. The inner bottom wall of the drainage groove 15 is arranged to be inclined downward toward one end of the drainage port 16.

[0058] According to this embodiment, when the bristles 8 enter between the water squeezing plate 9 and the roller body 7 and are squeezed to remove dirt, the sewage will gather downward and enter the water collecting trough 15, and will be discharged from the drain port 16 under the drainage action of the water collecting trough 15. The sewage discharged from the drain port 16 will slide along the water squeezing plate 9 below the drain port 16, thereby achieving drainage of the sewage and preventing a large amount of sewage generated by the removal of dirt from the upper bristles 8 from falling onto the lower bristles 8.

[0059] In another preferred embodiment, Fig.11 , Fig.12As shown, the bottom end of the drain port 16 is in a state of penetrating the lower surface of the circular portion 4.2, and a drainage groove 17 whose width matches the bottom width of the drain port 16 is provided on the surface of the squeezing plate 9 located below the water collecting tank 15. The sewage discharged from the drain port 16 will enter the drainage groove 17, and the drainage groove 17 can better prevent the sewage from falling onto the bristles 8 below, further improving the decontamination effect of the bristles 8.

[0060] like Fig.11 , Fig.12 As shown, a support block 18 can be fixedly arranged in the drain port 16, and both ends of the support block 18 are connected to the side walls of the circular portion 4.2. The top of the support block 18 is supported on the bottom of the squeezing plate 9 located above it, and there is a gap at the bottom of the support block 18 that communicates with the drainage groove 17, and the sewage is introduced into the drainage groove 17 through the gap at the bottom of the support block 18. The top of the support block 18 has a triangular through hole with the tip facing downward, which can play the role of an overflow hole.

[0061] The scope of protection claimed by the present invention is not limited to the above specific embodiments.
