During actual use, the cross groove 5241 effectively increases the friction and anti-slip performance between the driving wheel 524 and the plate beam, so that the roller component 52 can avoid deviation and slipping when driving the cleaning mechanism 2 to move on the plate beam; secondly, the spring damping 522 effectively increases the buffering performance of the roller component 52 during movement, which has a shock-absorbing effect on the cleaning device, so that the cleaning device will not vibrate significantly when moving, effectively improving the safety and stability of the cleaning device.

[0069] In an optional embodiment, a locking component is provided on the inner side of the driving wheel 524 to improve the safety and stability of the cleaning device, improve work efficiency, and reduce manpower.

[0070] like Fig.12 As shown, another embodiment of the present invention provides a method for using a cleaning device for a hinged joint between plate beams, comprising the following steps:

[0071] S1: Checking that the cleaning device can operate normally, placing the cleaning device into the hinged gap to be cleaned, and supporting the cleaning device via the driving wheel 524;

[0072] S2: The driving motor 221 is rotated through an external power controller to drive the slide 223 to move up and down along the ball screw 222 to change the inner angle between the first connecting rod 231 and the second connecting rod 232 so that the cleaning mechanism 2 can adapt to the shape of the hinged seam. After that, the driving motor 221 is controlled to stop.

[0073] S3: The driving motor 211 is rotated by an external power controller, so that the main shaft 212 drives the cleaning mechanism 2 to clean the outer wall area of ​​the hinged joint. After the hinged joint in this area is cleaned, the cleaning device is pushed to move along the hinged joint by the push handle 51;

[0074] S4: After the same height area of ​​the hinged joint is cleaned, the driving motor 211 is controlled to stop, the cleaning mechanism 2 is raised by the lifting mechanism 4, step S2 is repeated to adjust the cleaning mechanism 2 to adapt to the shape of the hinged joint, and step S3 is repeated to complete the cleaning of the same height of the hinged joint;

[0075] S5: During the cleaning process, when the waste chips in the collecting box 31 are full, the cleaning device is moved out of the hinged gap, and the waste chips in the collecting box 31 are removed by pulling the handle 332 to open the drawer 33;

[0076] S6: Repeat step S4 until the hinged seam is cleaned, and remove the cleaning device.

[0077] Preferably, in step S3, the cleaning mechanism 2 cleans the side walls of the hinged joint between the plate beams alternately through the scraper 233 and the brush member 234. The scraper 233 can scrape off the debris on the hinged joint wall with the help of several arc-shaped scrapers on its outer side, and then cleans it with the help of the brush member 234, thereby forming a reciprocating alternation to complete the cleaning of the hinged joint.

[0078] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0079] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0080] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art will readily understand that the above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
