[0032] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0033] refer to Figure 1-8 This embodiment provides a road bridge guardrail cleaning and maintenance device, which is mounted on a motor vehicle 100 equipped with a water storage tank 200 through a cantilever, and the cantilever horizontal displacement device and lifting device are mounted on the motor vehicle 100, thereby controlling the cleaning and maintenance device to move up and down and forward and backward along the extension direction of the guardrail 300. The horizontal displacement device and lifting device both adopt existing technologies, and the specific structure is not described in detail here.

[0034] The cleaning and maintenance device includes a frame 1, the length direction of the frame 1 is horizontal, and the width direction is longitudinal; two cleaning structures 2 that can be moved horizontally on the frame 1 are arranged along the longitudinal direction of the frame 1, and the two adjacent cleaning structures 2 are symmetrical and staggered; the cleaning structure 2 includes a mounting frame 21, a cleaning belt 22 arranged in an annular shape, a roller group, a water trough 24 and a power source 27, the mounting frame 21 includes a horizontally arranged base 211 and vertical arms 212 arranged parallel to both sides of the lower end of the base 211, the cleaning belt 22 is tensioned between the base 211 and the two vertical arms 212 through the roller group, the roller group includes an active roller 231 and a passive roller 232, the active roller 231 is driven to rotate by the power source 27, and drives the cleaning belt 22 to be transported, and bristles are arranged on the cleaning belt 22, the bristles are thick fluff, and the bristles are detachably arranged on the cleaning belt 22 through a fixed structure, and the fixed structure can be a structure such as Velcro, a buckle or a bolt to facilitate the replacement of the bristles. The power source 27 is a hydraulic motor.

[0035] The water trough 24 is fixedly installed on the base 211, and the water in the water trough 24 is connected to the water tank 200 through a circulating water system. The part of the cleaning belt 22 located at the upper end of the vertical arm 212 is guided by a plurality of guide rollers 25 so that it is partially immersed in the water trough 24. The guide rollers 25 are arranged in the water trough 24. The cleaning belt 22 is driven by an active roller 231, enters the water trough 24 for cleaning through the guide rollers 25, and is then guided by the guide rollers 25 to be output to the outside for operation. The water trough 24 is provided with a squeezing roller 26 at the output of the cleaning belt 22 for squeezing the water on the cleaning belt 22.

[0036] When in use, the surface of the cleaning belt 22 which is tensioned on the vertical arm 212 and faces the vertical arm 212 of the adjacent cleaning structure 2 is the cleaning surface 2201. The position of the cleaning and maintenance device is adjusted so that the cleaning surfaces 2201 of the two cleaning structures 2 are respectively located on both sides of the guardrail 300. Then the power source 27 is started to drive the roller group to rotate and drive the cleaning belt 22 to drive, thereby cleaning the guardrail 300. During the cleaning process, due to the setting of the water tank 24, the bristles on the cleaning belt 22 are immersed in the water tank 24 under the guidance of the guide roller 25. The bristles on the cleaning belt 22 are moistened and rinsed with water in the water tank 24 to ensure the cleanliness of the bristles, so as to facilitate the continuous cleaning of the guardrail 300. Before the cleaning belt 22 is output from the water tank 24, the excess water on the cleaning belt 22 is squeezed by the squeezing roller 26 to avoid a large amount of water splashing around on the bristles during the cleaning process, so as to keep the working environment clean and save water resources.

[0037] In this embodiment, the side of the cleaning belt 22 without bristles is the back side, and the cleaning belt 22 is provided with a limiting strip 221 along its length direction on the back side, and the surfaces of the active roller 231 and the passive roller 232 that are in contact with the back side of the cleaning belt 22 are provided with limiting grooves 2301 that are compatible with the limiting strip 221. Through the cooperation of the limiting strip 221 and the limiting groove 2301, the cleaning belt 22 is limited to prevent the cleaning belt 22 from deviating during the transmission process, thereby ensuring that the cleaning belt 22 can be transmitted stably.

[0038] In this embodiment, the frame 1 is provided with a driving mechanism for driving the cleaning structure 2 to move horizontally on the frame 1, and the driving mechanism includes a motor 31, a screw rod 32 and a nut seat 33.

Guide rods 34 are also provided on both sides of the screw rod 32, and the mounting frame 21 is provided with a guide seat 35, and the guide rod 34 is penetrated on the guide seat 35. Driven by the motor 31, the screw rod 32 rotates, thereby driving the nut seat 33 and the cleaning structure 2 to move horizontally on the frame 1, so as to adjust the lateral distance between two adjacent cleaning structures 2 according to the thickness of the guardrail 300, thereby greatly improving the scope of application of the structure of the present invention.

[0039] In this embodiment, baffles 213 are provided on the side between the two vertical arms 212 close to the ground and on the side away from the guardrail 300, which can effectively prevent the water remaining on the cleaning belt 22 from being thrown out during the cleaning process and affecting the surrounding environment, and can also prevent the ground from directly contacting the cleaning belt 22. In addition, the design of the baffle 213 also takes safety into consideration, and can prevent the operator from accidentally touching the rotating cleaning belt 22 or the roller group, thereby improving the safety performance of the overall device.

[0040] In this embodiment, a liquid level sensor 5 is provided in the water tank 24 to monitor the water level in the water tank 24 to ensure that the cleaning belt 22 can always be completely immersed in water during the cleaning process to maintain a stable cleaning effect.

[0041] In this embodiment, an ultrasonic generator 4 is also provided in the water tank 24. The ultrasonic generator 4 is suspended on the nut seat 33 through a rope and immersed in the water of the water tank 24. The ultrasonic wave generated by the ultrasonic generator 4 when working can form a strong micro-jet at the part of the cleaning belt 22 immersed in the water tank 24, effectively impacting the stains and impurities on the cleaning belt 22, enhancing the cleaning effect of the cleaning belt 22, and improving the cleaning efficiency.

The return pump 64 is arranged on the return pipe 62. Among them, the filter device 65 mainly adopts the existing method of multi-stage filter + activated carbon for combined filtration, and the specific structure is not repeated here. In actual use, the water in the water tank 24 is filtered regularly to ensure the cleanliness of the water in the water tank 24 and avoid the accumulation of stains and impurities that affect the cleaning effect.

[0043] In this embodiment, a controller is also included to monitor the power source 27, the motor 31, the liquid level sensor 5, the ultrasonic generator 4, and the water inlet pump 63 and the water return pump 64 in the circulating water system and issue control instructions according to the preset logic and control algorithm. The controller is preferably a PLC, such as Siemens S7-1200 or S7-1500 series. The liquid level sensor 5 is connected to the PLC through an analog input module or a communication module to provide real-time water level monitoring data. The water inlet pump 63, the water return pump 64, the power source 27 and the motor 31 are started and stopped by the controller controlling the relay or directly controlling the frequency converter.
