[0002] As an important facility to ensure traffic safety, road guardrails are widely distributed on various roads. With the continuous increase in traffic volume and the increasingly complex urban environment, a lot of dust accumulates on road guardrails that have been used for a long time. In order to create a civilized and hygienic city, road guardrails need to be cleaned.

[0003] If the road guardrails are cleaned manually, the cleaning staff will hold cleaning tools such as rags and brushes to wipe and clean the guardrails one by one. This method has many disadvantages. First, manual cleaning is inefficient and requires a lot of manpower and time. Especially in areas with long guardrails such as urban main roads and highways, cleaning work often requires a lot of manpower and material resources, and the progress is slow. Secondly, manual cleaning is labor-intensive, and cleaning staff need to work on the road for a long time, facing traffic risks.

[0004] In order to solve the above problems, the sanitation department has developed and put into use a number of sanitation vehicles for road guardrail cleaning. For example, a Chinese patent with publication number CN111719474A discloses a pure electric multifunctional guardrail cleaning vehicle, which includes an electric chassis and a water tank assembly, a transparent cavity is arranged between the electric chassis and the water tank assembly, a track from left to right is arranged at the bottom of the cavity, a side shift frame is movably installed on the track, a side shift drive mechanism is installed on the side shift frame, a rotating mechanism is installed on the side shift frame, a vertical lifting mechanism is fixed on the rotating mechanism, a horizontal telescopic mechanism is hinged on the top of the vertical lifting mechanism, a pitch cylinder is hinged on the side of the vertical lifting mechanism, and the other end of the pitch cylinder is hinged on the horizontal telescopic mechanism, and a roller brush device is installed on the horizontal telescopic mechanism, and the roller brush device includes an outer roller brush mechanism and an inner roller brush mechanism.

[0005] When using the sanitation vehicle described in the above patent to clean the road guardrail, the operator drives the vehicle close to the road guardrail and moves along the laying direction of the road guardrail. During the movement, the guardrail cleaning structure set on the sanitation vehicle can achieve the cleaning of the guardrail, which significantly improves the efficiency compared to manual cleaning of the guardrail.

DETAILED DESCRIPTION

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0026] like Figure 1-14 As shown, in order to change the current situation that the use of a larger sanitation vehicle to clean the road guardrail affects the normal driving of social vehicles, this embodiment provides a new smaller guardrail cleaning device, which includes a tricycle 1, a water tank 2 and a first cleaning component 3. The water tank 2 and the first cleaning component 3 are both arranged on the frame of the tricycle 1, and the tricycle 1 is an existing device, which can be a fuel-type tricycle 1 or a storage-type tricycle 1. When the existing tricycle 1 is used to carry the water tank 2 and the first cleaning component 3, after removing the rear compartment of the existing tricycle 1, the water tank 2 is installed on the frame of the tricycle 1, and the tricycle 1 provides electrical energy for the cleaning structure of the device. When the staff drives the smaller tricycle 1 along the direction of the road guardrail, it only occupies part of the driving lane, providing the possibility for the rear vehicle to deviate from the center of the driving lane and pass through the cleaning device, or reducing the area of ​​the adjacent lane occupied by the rear vehicle when changing lanes, reducing the impact of road guardrail cleaning on vehicle driving, or reducing the probability of traffic accidents caused by vehicle lane changes. When the tricycle 1 is traveling, the first cleaning assembly 3 works to clean the road guardrail.

[0027] In order to stably install the water tank 2 on the frame of the tricycle 1, a base 22 is provided at the bottom of the water tank 2. The base 22 is provided as a frame structure and is bolted to the frame of the tricycle 1. After the base 22 is stably installed on the tricycle 1, the lower end of the water tank 2 is inserted into the base 22. In addition, a railing 24 is provided at the opening at the rear end of the base 22, and the position of the water tank 2 is limited by the railing 24.

[0028] In order to be able to disassemble the railing 24 as required and to facilitate the disassembly of the water tank 2, a slot 25 is provided at the rear end of the base 22, and a plug rod 26 is provided at both ends below the railing 24. The plug rod 26 is inserted into the slot 25 to achieve the detachable connection between the railing 24 and the base 22. In addition, a drain pipe is provided at the bottom of the water tank 2, which is arranged just below the railing 24, and a solenoid valve is provided on the drain pipe, and a water pump 21 is provided on the side of the solenoid valve. Therefore, when the solenoid valve is turned on, the water in the water tank 2 can be controlled by the water pump 21 to flow to the spray pipe 5. Since the spray pipe 5 is arranged on the side of the first cleaning component 3, it can assist the first cleaning component 3 in cleaning the road guardrail.

[0029] In order to be able to clean the guardrail through the first cleaning component 3, the first cleaning component 3 includes a second motor 35, a shielding shell 32, multiple sets of bristles 31, etc., and a bracket 7 is arranged on the side of the first cleaning component 3. The second motor 35, the shielding shell 32, and multiple sets of bristles 31 are all arranged on the bracket 7, which provides convenience for the multiple sets of bristles 31 to work to clean the road guardrail.

[0030] Specifically, the bracket 7 includes a bottom frame 71, a diagonal bracing tube 72, two second transverse tubes 73, a fixing frame 74, etc. The bottom frame 71 is connected to the base 22, the two second transverse tubes 73 are arranged in parallel on the sides of the top of the bottom frame 71, and are detachably connected to the bottom frame 71, and the fixing frame 74 is detachably arranged on the two second transverse tubes 73 away from the bottom frame 71. Therefore, the diagonal bracing tube 72 is used to connect the lower second transverse tube 73 and the bottom frame 71, so that the second transverse tube 73 is stably installed on the tricycle 1.

[0031] The multiple sets of bristles 31 are divided into two groups arranged in parallel. In each group, the multiple sets of bristles 31 are sleeved on the same central axis 363. A top shaft 36 is fixedly arranged on the top of each central axis 363. A connecting mechanism 37 is sleeved on the top shaft 36, and the connecting mechanism 37 is adjustably sleeved on the two second transverse tubes 73. The shielding shell 32 is installed below the connecting mechanism 37 and is arranged on the side of the bristles 31. The second motor 35 is also arranged on the side of the second transverse tube 73, and sprockets are arranged on the power transmission shaft of the second motor 35 and the top shaft 36. The multiple sprockets are connected by chains. Therefore, under the operation of the second motor 35, the two central axes 363 can be controlled to rotate, thereby driving the bristles 31 to move, thereby achieving the cleaning of the road guardrail.

[0032] In order to facilitate the rotation of the jacking shaft 36 and achieve the adjustable connection between the connecting mechanism 37 and the second horizontal pipe 73. The connecting mechanism 37 includes a connecting frame 372 and two sets of bearing seats 371. The two sets of bearing seats 371 are sleeved on the jacking shaft 36 up and down and are installed on the side of the connecting frame 372. Two sleeve pipes 373 are fixedly arranged on the side of the connecting frame 372. The two sleeve pipes 373 of each connecting frame 372 are respectively sleeved on two second horizontal pipes 73. At the same time, an internally threaded pipe 374 is arranged on the connecting frame 372. The internally threaded pipe 374 is arranged between the two sleeve pipes 373. The internally threaded pipes 374 of the two connecting frames 372 are threadedly sleeved on both ends of the same bidirectional screw 34. The bidirectional screw 34 is arranged between the two second horizontal pipes 73, and the end is connected through a bearing and penetrates through the fixed frame 74 and is directly connected to the first motor 33 or is connected to the first motor 33 through a gearbox. The first motor 33 is installed on the fixed frame 74. Therefore, when the first motor 33 works, the bidirectional screw 34 rotates, and then controls the relative movement of the two connecting frames 372, and then adjusts the positions of the two sets of connecting mechanisms 37, realizing the adjustment of the positions of the central shaft 363 and the brush hairs 31, providing convenience for the two sets of brush hairs 31 of the first cleaning assembly 3 to be arranged on both sides of the road guardrail to achieve cleaning.

[0033] In order to still be able to control the rotation of the brush hairs 31 by the second motor 35 when the position of the brush hairs 31 is adjustable, a movable frame 6 is arranged between the two sets of connecting mechanisms 37. The movable frame 6 is vertically sleeved on the second horizontal pipe 73 in an adjustable manner, and a sprocket is arranged at the top. The sprocket is meshed and connected with the chain, that is, the sprockets on the second motor 35, the jacking shaft 36 and the movable frame 6 are connected by a unified chain, and when the position of the brush hairs 31 is adjusted, by adjusting the movable frame 6, the chain can still be meshed and connected with the sprocket, providing convenience for controlling the rotation of the two sets of brush hairs 31 by the second motor 35.

[0034] In order to realize the adjustment of the movable frame 6, a guide rod 76 is vertically arranged on the side of the second horizontal pipe 73. The movable frame 6 is arranged in a C-shaped structure, and at the same time, the movable frame 6 is vertically sleeved on the second horizontal pipe 73. Therefore, the guide rod 76 penetrates through the end of the movable frame 6. A second nut is threadedly sleeved on the end of the guide rod 76 protruding from the movable frame 6, and a second spring 75 in a compressed state is arranged between the movable frame 6 and the second nut. Under the action of the second spring 75, the end of the movable frame 6 is forced to always have a tendency to approach the second horizontal pipe 73, and the chain is pulled through the sprocket, so that the chain is meshed and connected with other sprockets.

[0035] In order to adjust the height of the bristles 31 according to the needs, and to make the bracket 7 stably connected to the base 22. The base frame 71 includes a bottom tube 711, a sleeve 714 and a lifting frame 713. The bottom tube 711 and the sleeve 714 are both installed on the base 22. A plug 712 is vertically arranged on the bottom tube 711. The plug 712 is inserted into the lifting frame 713. The sleeve 714 is sleeved on the lifting frame 713. Therefore, under the cooperation of the bottom tube 711 and the sleeve 714, the lifting frame 713 is stably and movably arranged on the side of the base 22. A second end tube 716 is arranged on the top of the lifting frame 713. The second end tube 716 is connected and inserted into the second transverse tube 73 by bolts. Therefore, the first cleaning component 3 is stably arranged on the side of the base 22. In addition, an adjusting screw 715 is threadedly provided on a certain sleeve 714, and the top of the adjusting screw 715 is connected to the lifting frame 713 through a bearing. By rotating the adjusting screw 715, the height of the lifting frame 713 can be adjusted, and then the height of the first cleaning component 3 can be adjusted to provide support to meet different work requirements.

[0036] In order to stably sleeve the bristles 31 on the central shaft 363, a base plate 364 is fixedly provided at the bottom of the central shaft 363, and a first nut 361 is threadedly sleeved on the top, and a limiting column 362 is provided between the first nut 361 and the base plate 364, and the limiting column 362 is provided along the length direction of the central shaft 363. A support tube 311 is fixedly provided in the middle of each set of bristles 31, and a limiting groove 312 is provided on the inner side of the support tube 311, and the limiting column 362 is provided through the limiting groove 312, so that the support tube 311 is stably placed relative to the central shaft 363, and can then rotate with the central shaft 363 to achieve the cleaning of the road guardrail.

[0037] In order to control the operation of the motor and the water pump 21, a control box 23 is provided on the side of the base 22. The control box 23 is an existing device, and a controller, a relay, a contactor, a circuit breaker, etc. are provided inside the control box. Example

The two cleaning mechanisms 41 are symmetrically arranged, and the top is sleeved on the first transverse tube 43. At the same time, the third motor 42 is connected and installed at the end of the first transverse tube 43 through the fixing frame 74. The power transmission shaft of the third motor 42 is connected to the bidirectional screw. The two ends of the bidirectional screw thread respectively penetrate the two cleaning mechanisms 41. Therefore, when the third motor 42 is working, the bidirectional screw is controlled to rotate forward and reverse, thereby controlling the relative movement of the two cleaning mechanisms 41. The above arrangement can control the cleaning mechanism 41 to fit the road guardrail, and control the lifting and lowering of the cleaning mechanism 41 to achieve secondary cleaning of the road guardrail.

[0039] Specifically, the cleaning mechanism 41 includes cleaning cotton 413, a support plate 414, a frame 411, an end frame 412, etc. Two cleaning cottons 413 are respectively arranged on two support plates 414, and a frame 411 is arranged on the side of the two support plates 414 away from each other, and the top of the frame 411 is sleeved with an end frame 412. The two sets of end frames 412 are sleeved on the first horizontal tube 43 distributed up and down, and are threadedly sleeved on the same bidirectional screw, and the end of the bidirectional screw is connected to the third motor 42.

[0040] The ends of the two first transverse tubes 43 are fixedly provided with first end tubes 431, and the two first end tubes 431 are sleeved on the same vertical tube 46. A supporting tube 462 and a limiting tube 461 are provided at the bottom of the vertical tube 46, and a snap plate 463 is fixedly provided on the side where the supporting tube 462 and the limiting tube 461 are close to each other.

The snap plate 463 is installed in the snap groove 471, so as to realize the movable connection between the installation frame 47, the supporting tube 462 and the limiting tube 461. A blocking plate 472 is provided at the end of the buckle groove 471, and a limiting rod 474 is fixedly provided on the blocking plate 472. A first spring 473 is sleeved on the limiting rod 474, and the end of the limiting rod passes through the supporting tube 462 and the limiting tube 461. The first spring 473 is in a compressed state, and the two ends are respectively in contact with the blocking plate 472 and the supporting tube 462 and the limiting tube 461. Under the action of the first spring 473, the vertical tube 46 can be controlled to be stably set at the end of the mounting frame 47. At the same time, when the tricycle 1 moves forward relative to the vertical tube 46, the first spring 473 can be compressed to deform, so that the vertical tube 46 moves relative to the tricycle 1 to avoid damage to the device.
