Description

Technical Field

[0001] The utility model relates to the technical field of environmental sanitation equipment, and particularly, to a portable guardrail cleaning machine. Background Art

[0002] With the development of technology, transportation has become more convenient. As the number of vehicles continues to increase, roads have been continuously widened. To improve safety and not affect traffic convenience, people have set up road guardrails in the middle of the road, which improves road safety and maintains traffic order. Generally, road guardrails are exposed on the road for a long time, and it is easy to accumulate dust, affecting the appearance. Therefore, people have started to use road guardrail cleaning machines to clean the guardrails regularly to maintain the appearance. The road guardrail cleaning machine has played a certain role in promoting the beautification of the road. However, general road guardrail cleaning machines are relatively large, and there is no optimization for sewage splashing. When the cleaning device rotates, it will cause sewage splashing. If there are pedestrians on the road, it will have a bad impact on pedestrians. Moreover, the thickness of current road guardrails is not uniform, and general road guardrail cleaning machines are difficult to automatically adjust the width between the cleaning devices during cleaning, which will cause incomplete cleaning of some parts of the guardrail and the working efficiency is not fast enough.

Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0020] Embodiment

[0021] Referring to the accompanying drawings of the specification, in an embodiment of the present utility model, a portable guardrail cleaning machine includes a quick-change support frame assembly 1 fixedly installed on the frame of a cleaning vehicle. A rotary support arm assembly 2 is hingedly installed on the quick-change support frame assembly 1. The other end of the rotary support arm assembly 2 is hingedly connected to a column, and a sliding motor assembly 8 perpendicular to the column is fixedly installed at the top of the column. The end of the sliding motor assembly 8 is also hingedly connected to another set of sliding motor assemblies 8. Hydraulic power motor assemblies 10 are installed on both of the sliding motor assemblies 8. A foam brush assembly 9 is drivingly installed on the output shaft of the hydraulic power motor assembly 10. The sliding motor assembly 8 includes a motor, a gear-rack drive, a slide rail and a mounting bracket. The motor is fixedly installed on the mounting bracket. The mounting bracket is slidably installed on the slide rail. The hydraulic power motor assembly 10 is fixedly installed on the mounting bracket.

[0022] An expansion oil cylinder 3 is hingedly installed between the quick-change support frame assembly 1 and the rotary support arm assembly 2, and between the rotary support arm assembly 2 and the column. A brush rotary expansion oil cylinder 12 is connected and installed at the hinge between the two sliding motor assemblies 8. The two ends of the brush rotary expansion oil cylinder 12 are respectively hinged to the two sliding motor assemblies 8. A brush fixing support frame assembly 11 is fixedly installed on the bottom plate of the last sliding motor assembly 8. Protective covers composed of a front protective cover 4 and a rear protective cover 5 are provided on both the brush fixing support frame assembly 11 and the column. A front high-pressure spray 6 and a rear high-pressure spray 7 are respectively provided inside the front protective cover 4 and the rear protective cover 5. A number of sensors 13 are installed on the edges of the openings of the front high-pressure spray 6 and the rear high-pressure spray 7.

[0023] Usage process:

[0024] During use, first connect and fix the quick-change support frame assembly to the front frame of the vehicle. The left-right rotation of the front-end cleaning device to meet the angle requirements is achieved through the telescopic oil cylinder. Two hydraulic motors of the hydraulic system drive the brush assemblies respectively. At the same time, high-pressure spray jets at the front and rear ends synchronously supply water to the brushes. Since the brushes are worn after long-term use, it is necessary to adjust the distance between the two brush assemblies by driving the hydraulic motor assembly through the top sliding motor according to the degree of brush wear. During operation, the sensor on the protective cover synchronously monitors the safety distance between the guardrail and the protective cover (a warning will be issued when it is less than 100 mm). The outer brush assembly rotates up and down through the push-pull force of the brush rotation and telescopic oil cylinder by the rotating shaft. The designed cleaning nozzles can clean the surface of the guardrail in all directions to ensure thorough cleaning; using high-pressure water flow for cleaning can effectively remove stubborn dirt and stains; the overall structure is stable and durable, can be used for a long time without damage, and reduces the maintenance cost.

[0025] During the above process, a protective cover composed of a front-end protective cover and a rear-end protective cover is arranged outside the foam brush assembly. When the brush rotates, it can block sewage, effectively control sewage splashing, and have less impact on pedestrians and vehicles; the sliding motor assembly can adjust the distance between the two brush assemblies, can cope with guardrails of different thicknesses, and further improves the practicability of the product and the cleaning effect; during operation, the sensor on the protective cover synchronously monitors the safety distance between the guardrail and the protective cover to prevent collisions with the guardrail and improves safety; the structure of this application is simple, highly practical, and easy to operate, worthy of promotion.
