Description

Technical Field

[0001] The utility model relates to the technical field of cleaning robot manufacturing, in particular to a cleaning robot for cleaning tunnel bridge accessories, specifically a cleaning module of a cleaning robot. Background Art

[0002] When constructing a tunnel, cable trays are often used to lay cables, and the cable trays are formed by connecting a series of tray components end to end. Existing tunnel cable trays are also equipped with accessories such as lighting fixtures and cameras. To ensure the normal operation of these accessories, they need to be cleaned regularly, but the regular cleaning of these accessories has become a major problem. Previously, the regular cleaning of these accessories was mostly completed manually. When performing cleaning operations, it was necessary to close half of the road, which not only affected traffic but also posed a significant safety hazard to the operators.

[0003] With the continuous development of robot technology, the current cleaning work can be completed by an orbital cruise cleaning robot. For example, the "Orbital Full-Automatic Tunnel Lighting Fixture Cleaning Device" with the application number CN201320740226.6 discloses a cleaning device. A longitudinal track is installed in the tunnel. The longitudinal track is close to the inner wall of the tunnel lining layer and is parallel to the tunnel axis. A traveling device is installed on the longitudinal track, and the traveling device can move along the longitudinal track. A cleaning device is installed on the traveling device through a telescopic mechanism. The cleaning device is an electric cleaning brush or a towel. A large amount of dust adheres to the tunnel accessories. Cleaning only with a brush or a towel has very limited cleaning effects. Therefore, its cleaning structure needs to be further improved.

It is only for the convenience of describing the present utility model and is a simplified description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.

[0031] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0032] As Figures 1 to 7 shown, a cleaning module of a cleaning robot includes a connection bin 2 detachably connected to a moving module 1. A liftable cleaning bin 3 is connected to the connection bin 2. A water collecting tray 31 extends forward from the bottom of the cleaning bin 3. A rotary brush mechanism 4 is arranged above the water collecting tray 31 on the cleaning bin 3, and a spray pipe 5 is arranged on the rotary brush mechanism 4.

[0033] The specific structure for the liftability of the cleaning bin 3 is as follows: A driving device 61 and a screw rod 62 connected and driven by the driving device 61 are arranged in the cleaning bin 3. A connection frame 63 capable of moving along the axis direction of the screw rod 62 is screwed on the screw rod 62, and the cleaning bin 3 is fixed to the connection frame 63. The above driving device 61 is preferably a motor.

[0034] Guide rails 64 are respectively arranged on both sides of the screw rod 62, and sliders 65 slidably matched with the guide rails 64 are fixed on the connection frame 63.

[0035] The cleaning module of the utility model adopts a segmented structure consisting of a connecting chamber 2 and a cleaning chamber 3, and the cleaning chamber 3 can be raised and lowered to meet the cleaning requirements of accessories installed at different heights. The spraying operation can be performed by using the spray pipe 5 on the roller brush mechanism 4, and the surface of the accessories can be washed with water, which can greatly improve the cleaning effect; the spraying water is collected by the water collecting tray 31, and a filter cotton is arranged at the bottom of the water collecting tray 31. The filtered sewage in the water collecting tray 31 is pumped into the sewage tank by a pump. When the next accessory needs to be moistened before cleaning, the water in the sewage tank will be reused, which can ensure that sewage is not stored as much as possible and improve the utilization rate of water.

[0036] When the cleaning chamber 3 is lifted or lowered, the driving device 61 drives the screw rod 62 to rotate, so that the connecting frame 63 screwed on the screw rod 62 moves (lifts or lowers) along the axis direction of the screw rod 62, thereby driving the lifting or lowering of the cleaning chamber 3. The cooperation between the guide rail 64 and the slider 65 can make the lifting or lowering of the connecting frame 63 smoother.

[0037] In this embodiment, the roller brush mechanism 4 is fixed on the swing rod 7, and the swing rod 7 is connected to a swing motor 71. The swing motor 71 drives the swing rod 7 to rotate, thereby driving the roller brush mechanism 4 to swing as a whole, and the cleaning angle can be adjusted.

[0038] The roller brush mechanism 4 includes a base plate 41, a mounting plate 42 is installed on the base plate 41, a shock absorber 43 is arranged between the mounting plate 42 and the base plate 41, and a roller brush assembly driven to rotate by a roller brush driving device is arranged on the mounting plate 42, and the roller brush assembly includes a bristle brush cleaning roller brush 44 and a flannel cleaning roller brush 45.

[0039] The shock absorber 43 is preferably a spring. A shock absorber 43 is provided between the mounting plate 42 and the bottom plate 41. The spring is used for shock absorption, which can reduce the impact of vibration on the cleaning operation, so that the cleaning roller brush can always be in contact with the cleaning surface, thereby improving the cleaning effect. In this embodiment, a brush cleaning roller brush 44 and a flannel cleaning roller brush 45 are used to form a cleaning component, and the characteristics of cleaning roller brushes of different materials are used to achieve a better cleaning effect. Among them, the brush cleaning roller brush 44 is made of fiber material, has good cleaning ability, and can efficiently clean the dust on the surface of the accessory; the flannel cleaning roller brush 45 can quickly and effectively clean the dust on the surface of the accessory, and can also effectively absorb the waste water generated during cleaning.

[0040] The driving structure of the cleaning roller brush is as follows: a driving wheel 46 is connected to the roller brush driving device, and a synchronous wheel 47 is respectively connected to the bristle cleaning roller brush 44 and the flannel cleaning roller brush 45, a synchronous belt 48 is arranged outside the synchronous wheel 47, and the driving wheel 46 cooperates with the synchronous belt 48 in friction transmission, and a tensioning wheel 49 is arranged on the mounting plate 42, and the synchronous belt 48 is arranged outside the synchronous wheel 47 and the tensioning wheel 49.

[0041] The above-mentioned roller brush driving device is preferably a motor. The motor drives the driving wheel 46 to rotate, and then the driving wheel 46 drives the synchronous belt 48 to move. Then the synchronous belt 48 drives the synchronous wheel 47 to rotate (there is a tooth groove fit between the synchronous belt 48 and the synchronous wheel 47), thereby driving the roller brush to rotate. Further, a tensioning wheel 49 is provided on the mounting plate 42, and the synchronous belt 48 is arranged outside the synchronous belt 48 and the tensioning wheel 49. The setting of the tensioning wheel 49 can improve the tension of the synchronous belt 48 and avoid the slipping phenomenon caused by insufficient tension of the synchronous belt 48.

[0042] An air shower connector 42a is fixed on the mounting plate 42. The roller brush mechanism also has an air shower function. When in use, the air supply pipe is connected to the air shower connector 42a, and the power is supplied by a compressed air pump for air shower, which can quickly dry the accessories after cleaning.

[0043] A drag chain 8 is provided between the connection bin 2 and the cleaning bin 3. The setting of the drag chain 8 can protect power lines, signal lines, etc.

[0044] A hook groove 2a adapted to the hook 11 of the moving module 1 is provided on the connection bin 2.

[0045] Handles 21 are respectively provided on both sides of the connection bin 2.

[0046] The connection between the moving module 1 and the connection bin 2 of the cleaning module adopts a quick disassembly and assembly structure. When installing the cleaning robot, the moving module 1 is separated from the cleaning module, which can reduce the weight during handling. First, the moving module 1 is installed on the bridge, and then the cleaning module is hung on the moving module 1 by the cooperation of the hook groove 2a on the connection bin 2 and the hook 11 to form a preliminary fixation. Then, the respective pipelines are connected to fix the cleaning module and the moving module 1 together. The setting of the handles 21 facilitates the handling of the cleaning module.
