Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel reflective rings, relates to a highway tunnel reflective ring, and also relates to a self-cleaning device for tunnel reflective rings. Background Art

[0002] At present, after decades of construction of expressways, remarkable achievements have been made in the development of expressways in China. With its characteristics of high speed, fastness, and high efficiency, it has contributed greatly to the construction of China's transportation modernization and the development of the national economy. While achieving achievements, there are also some problems. In particular, it is difficult to carry out the maintenance work of tunnel reflective rings after the completion of expressway construction. Tunnel reflective rings are installed at the oncoming tunnel entrance and inside the tunnel to assist tunnel lighting, making the tunnel present a clear outline, enabling drivers and passengers to intuitively feel the length, width, and height of the tunnel, better master the vehicle distance, reduce the discomfort such as "instant blindness" when drivers enter and exit the tunnel entrance, play a warning and guiding role, improve the driving safety in the tunnel, resolve the dilemma caused by the inability to provide normal lighting in the tunnel, and at the same time reduce the power consumption and operation cost of tunnel lighting.

[0003] Reflective rings usually adopt aluminum-plastic board materials, with a layer of reflective material pasted on the outside. When the vehicle headlights shine on it, the reflective ring will reflect and emit light. The cross-section of the tunnel is usually an arc with non-equal diameters, but a sectional structure with different radii that is symmetric about the left and right. In order to adapt to this cross-section structure of the tunnel, the reflective ring also needs to be designed as a sectional structure to be fully matched with it.

[0004] After long-term use, the reflective material layer will have problems such as dirt on the surface, and the reflective effect will become worse and worse, affecting the driving safety in the tunnel. For the dirt problem, conventionally, manual cleaning is carried out regularly, which has a large labor intensity, is time-consuming and laborious, has poor safety, and the tunnel traffic needs to be suspended during the cleaning process, causing highway congestion. In view of the problems of manual cleaning, some people have also designed mechanical equipment. For example, Chinese Patent Application (Application No. 202123033805.0) discloses an intelligent cleaning robot for highway tunnel reflective rings, including an annular track arranged on one side of the reflective ring, and a cleaning mechanism for cleaning the reflective ring is arranged on the annular track. This structure has a large occupied space, it is difficult to install the cleaning mechanism, and the waterproof problem also needs to be considered. Moreover, the reflective ring is composed of discontinuous segmented plates spliced together, and there will be a sudden change at the transition. It is difficult for this annular track to meet the cleaning requirements of the spliced reflective ring of segmented plates, and the suspended installation of the reflective ring is difficult. And Chinese Patent Application (Application No. 202021930928.7) discloses a mobile tunnel cleaning robot, which uses a quarter-circular annular track fixed on a counterweight box, and a cleaning clamping plate mechanism is arranged on the annular track. The cleaning clamping plate mechanism is driven to move through a stepping motor connected to a flexible connection structure. This method requires manual transportation of the equipment to the corresponding reflective ring for cleaning, still has a large labor intensity, and cannot achieve automatic regular cleaning.

[0005] With the development of intelligent transportation based on big data, the design of the reflective ring can be more and more reasonable, and the segmented splicing technology of the reflective ring can be better solved. When installing the cleaning equipment for the reflective ring, the matching structure also needs to be considered during the design, so that the integrated cleaning equipment for the reflective ring can have a small occupied space, low design and operation costs. Existing reflective rings are difficult to achieve the above purposes. Summary of the Invention

Two rows of walking wheels are respectively installed at the front and rear of the upper part of the walking frame. The two rows of walking wheels are hung on two second card slots provided on the upper part of the reflective ring. The driving mechanism has a self-locking function and is installed on the walking frame to drive the walking wheels to walk along the arc-shaped reflective ring. The cleaning component is installed on the walking frame and elastically contacts the reflective surface of the reflective ring.

[0012] Preferably, the above-mentioned driving mechanism includes a driving motor, a worm, a worm gear, and an arc-shaped rack. The driving motor is installed on the walking frame.

[0014] Preferably, the above-mentioned cleaning component is a cleaning brush, a cleaning rubber strip, or a sponge strip.

[0015] A self-cleaning device for a highway tunnel reflective ring further includes a flushing component, and the flushing component is installed on both sides of the cleaning component.

[0016] The beneficial effects of the present invention: Compared with the prior art, the effects of the present invention are as follows: 1) The reflective ring structure of the present invention improves the strength and rigidity of the reflective ring through the U-shaped groove structures provided on the upper and lower parts, and is also convenient for accommodating the cleaning device, occupying a small space. When installed at the tunnel entrance, it plays a certain role in waterproofing and drainage. Moreover, during the cleaning process, it is also convenient for the cleaning sewage to drain from the U-shaped groove to the sewage channel, avoiding the direct dripping of the cleaning sewage directly, resulting in road slipperiness and affecting vehicle traffic. 2) The self-cleaning device accommodated in the reflective ring can automatically clean the reflective ring, greatly shortening the back-and-forth cleaning cycle, improving the labor efficiency of the operators, and also facilitating remote operation, reducing the cleaning and maintenance operators, saving time and effort, and greatly reducing the labor cost. The self-cleaning equipment is accommodated in the reflective ring, and the cleaning and operation of the self-cleaning equipment will not affect vehicle traffic during the process, avoiding the situation of highway congestion. Hanging upside down in the reflective ring, the walking wheel is driven to walk by a driving mechanism with a self-locking function, stopping while walking. The cleaning component cleans the reflective ring during the walking process, and the cleaning is stable. By controlling the timed walking, regular cleaning is realized. The equipment is small, the design and manufacturing cost is low, the occupied space is small, the power requirement is small, and the operation cost is low. Walking around the customized annular reflective plate will not cause problems such as difficult transition walking due to segmented splicing. 3) The worm and worm gear drive is adopted. The worm and worm gear have a self-locking function, which is convenient for realizing the automatic locking in the arc-shaped cantilever section during the walking process. And a driving gear is used to walk on the arc-shaped rack. The gear only serves as the power for walking drive, realizing a greatly simplified structure and a greatly reduced cost. 4) An auxiliary wheel is installed at the bottom of the walking frame to improve the rigidity of the walking frame. Since the cleaning component presses against the reflective ring to clean it, a reaction force is generated on the walking frame. After installing the auxiliary wheel, the two ends of the walking frame are supported, reducing the load perpendicular to the reflective ring direction of the top walking wheel. 5) The walking frame structure composed of the vertical rod, the first bent rod, the second bent rod, and the horizontal rod is light in weight, good in rigidity, high in strength, stable and reliable in walking, and convenient to be arranged in the reflective ring. 6) Install a flushing component to facilitate flushing and cleaning the reflective ring with cleaning liquid or clear water, enabling more thorough cleaning, reducing the number of back-and-forth operations, and lowering power consumption.
