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 brush roller mechanism 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 members 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 the cleaning operation, it was necessary to close one lane, 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 cleaning device disclosed in the patent application with the application number CN201320740226.6 and the name "Orbital Fully Automatic Tunnel Lamp Cleaning Device" installs a longitudinal track 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. However, the cleaning ability of this cleaning device is limited. Therefore, its cleaning structure needs to be further improved. Summary of the Utility Model

[0028] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description of the present utility model can be used in other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present utility model.

[0029] Those skilled in the art should understand that in the disclosure of the present utility model, the terms "longitudinal", "transverse", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position relationship shown in the drawings. 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.

[0030] It will be understood that the term "a" should be construed 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 "a" should not be construed as a limitation on the quantity.

[0031] As Figures 1 to 6 shown, a roller brush mechanism of a cleaning robot includes a bottom plate 11. An installation plate 12 is installed on the bottom plate 11. A shock absorber 13 is provided between the installation plate 12 and the bottom plate 11. A roller brush assembly driven to rotate by a driving device 2 is provided on the installation plate 12. The roller brush assembly includes a brush cleaning roller 31 and a flannelette cleaning roller 32. The brush cleaning roller 31 and the flannelette cleaning roller 32 are arranged on corresponding rotating shafts 33. One end of the rotating shaft 33 is provided with a quick-release mechanism. The quick-release mechanism includes a base 34 and a connecting member 35 that are detachably matched. The base 34 is fixed on the installation plate 12. Connecting heads 33a are respectively arranged at both ends of the rotating shaft 33. The connecting head 33a at one end of the rotating shaft 33 is connected to the connecting member 35. An elastic member 36 is provided between the connecting head 33a and the connecting member 35. The above elastic member 36 is preferably a spring.

[0032] The shock absorber 13 is preferably a spring. A shock absorber 13 is provided between the installation plate 12 and the bottom plate 11. By using the spring for shock absorption, the influence of vibration on the cleaning operation can be reduced, so that the cleaning roller can always be in contact with the cleaning surface, improving the cleaning effect. In this embodiment, the brush cleaning roller 31 and the flannelette cleaning roller 32 are used to form a cleaning assembly. By utilizing the characteristics of cleaning rollers made of different materials, a better cleaning effect can be achieved.

The flannelette cleaning roller 32 can quickly and effectively clean the dust on the surface of the accessory, and can also effectively absorb the waste water generated during cleaning.

[0033] The driving structure of the cleaning roller of the present utility model is as follows:

[0034] A driving wheel 21 is connected to the driving device 2. Synchronous wheels 22 are respectively connected to the rotating shaft 33. A synchronous belt 23 is arranged outside the synchronous wheels 22. The driving wheel 21 is in frictional transmission cooperation with the synchronous belt 23. The above driving device 2 is preferably a motor. The motor drives the driving wheel 21 to rotate, then the driving wheel 21 drives the synchronous belt 23 to move, and then the synchronous belt 23 drives the synchronous wheel 22 to rotate (the synchronous belt 23 and the synchronous wheel 22 are in tooth groove cooperation), thereby driving the rotating shaft 33 to rotate.

[0035] Further, a tension pulley 24 is provided on the mounting plate 12, and the synchronous belt 23 is arranged outside the synchronous pulley 22 and the tension pulley 24. The provision of the tension pulley 24 can improve the tension of the synchronous belt 23 and avoid the slipping phenomenon caused by insufficient tension of the synchronous belt 23.

[0036] A square groove 33b is provided on the connector 33a close to the driving device 2, and a square transmission block 33c adapted to the square groove 33b is provided at one end of the rotating shaft 33 close to the driving device 2. Transmission is achieved through the cooperation of the square transmission block 33c and the square groove 33b. The other end of the rotating shaft 33 uses the cooperation of a cylindrical transmission block and a cylindrical groove, and the other end is a rotational fit. That is to say, the connector 33a on one side of the quick-release mechanism does not rotate.

[0037] For the brush roller mechanism of the present utility model, a quick-release mechanism is provided at one end of the rotating shaft 33, which facilitates the disassembly of the rotating shaft 33 to facilitate the replacement of consumables (cleaning brush roller). Connectors 33a are provided at both ends of the rotating shaft 33. When replacing the consumables, only the connecting piece 35 needs to be removed so that the connector 33a on the side of the quick-release mechanism is separated from the rotating shaft 33.

[0038] A cleaning spray water pipe 4 is provided beside the brush roller assembly, and spray holes 4a are arranged at intervals on the cleaning spray water pipe 4.

[0039] The cleaning spray water pipe 4 is fixed to the mounting plate 12 through a spray water pipe bracket 41.

[0040] The brush roller mechanism of the present utility model has a spraying function. During use, a water supply pipe is connected to the cleaning spray water pipe 4, and spraying operations are carried out using the spray holes 4a on the cleaning spray water pipe 4, and spraying of cleaning liquid and clean water can be performed.

[0041] An air shower connector 5 is fixed on the mounting plate 12. The brush roller mechanism of the present utility model also has an air shower function. During use, an air supply pipe is connected to the air shower connector 5, and air shower is carried out by the power supplied by a compressed air pump, which can quickly dry the accessories after cleaning.

[0042] Ultrasonic detection sensors 6 are provided on both sides of the mounting plate 12.

[0043] Brackets 61 are fixed on both sides of the mounting plate 12, and a sliding frame 62 that is slidably matched with the brackets 61 is assembled on the brackets 61. The ultrasonic detection sensors 6 are fixed on the corresponding sliding frames 62.

[0044] The position of the accessory is detected by ultrasonic waves to achieve the purpose of automatic cleaning.

[0045] The above are only the preferred embodiments of the present utility model, and thus do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the solutions obtained by equivalent substitutions and obvious changes made by using the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
