[0043] Please refer to the following: Figures 1 to 9 The roller assembly provided in this application will now be described. The roller assembly includes a connecting plate 1 and a plurality of roller bodies 5.

[0044] The connecting plate 1 is used to be fixedly installed on the traveling frame 9. The connecting plate 1 has two side plates 11 that extend downward and are located on both sides of the guide beam 8. Each side plate 11 has a plurality of mounting seats 2 that are spaced apart along the length of the guide beam 8. Each mounting seat 2 is located on the upper or lower side of the flange 81 of the guide beam 8, and the side of the mounting seat 2 facing the flange 81 is provided with a groove 21.

[0045] Multiple roller bodies 5 are fitted into multiple grooves 21 in a one-to-one correspondence. Each roller body 5 adopts a cylindrical structure, and the axial direction of the roller body 5 is parallel to the direction of the side plate 11 toward the guide beam 8.

[0046] When the roller body 5 is embedded in the groove 21, the outer peripheral wall of the roller body 5 abuts against the flange 81, so that the roller body 5 is suitable for rotating about its own central axis.

[0047] In this embodiment, after the traveling frame 9 is installed on the guide beam 8, the connecting plate 1 is fixedly installed on the traveling frame 9. The connecting plate 1 has two side plates 11 extending downward and located on both sides of the guide beam 8. Each side plate 11 has multiple mounting seats 2, and each mounting seat 2 has a groove 21. Multiple roller bodies 5 are embedded in the multiple grooves 21 one by one, and the outer peripheral wall of the roller body 5 abuts against the flange 81 on the guide beam 8. When the traveling frame 9 moves along the guide beam 8, each roller body 5 is adapted to rotate about its own central axis.

[0048] Compared with the prior art, the roller assembly provided in this application adopts a shaftless mounting structure for the roller body 5, which avoids the effect of shear stress on the roller body 5 and improves the service life of the roller assembly for the traveling device.

[0049] In some embodiments, please refer to the following: Figure 2 , Figures 4 to 7 and Figure 9 As one specific embodiment of the roller assembly provided in this application, the mounting base 2 also includes an end cap 3.

[0050] The end cap 3 is located on the side of the mounting base 2 facing the flange 81 and is connected to the mounting base 2 through the connecting structure 4; the end cap 3 has a rotating groove for the roller body 5 to be inserted, and the roller body 5 is rotatably connected to the rotating groove.

[0051] The end cap 3 has a through hole 31 that is suitable for communicating with the groove 21, and the through hole 31 is connected to the rotating groove. When the end cap 3 and the mounting base 2 are connected, part of the roller body 5 extends through the through hole 31 and abuts against the flange 81, and the end cap 3 abuts against the roller body 5 to restrict the roller body 5 from leaving the groove 21.

[0052] By adopting the above technical solution, the end cap 3 plays a limiting role. When installing the roller body 5, the end cap 3 can ensure that the roller body 5 is always in the groove 21, and prevent the roller body 5 from falling out of the groove 21 during installation. During the use of the roller assembly, the end cap 3 can also prevent the roller body 5 from shifting.

[0053] In some embodiments, please refer to the following: Figures 4 to 9 As a specific embodiment of the roller assembly provided in this application, the connecting structure 4 includes a first boss 41, a second boss 42, and a fixing bolt 43.

[0054] The first boss 41 is provided on the end cover 3 and extends outward in the horizontal direction; the first boss 41 has a positioning hole that runs through in the vertical direction.

[0055] The second boss 42 is provided on the mounting base 2, and a threaded groove is provided on it that opens towards the flange 81, so that when the mounting base 2 and the end cover 3 are connected, and the through hole 31 and the groove 21 are connected, the positioning hole and the threaded groove are connected.

[0056] The fixing bolt 43 is adapted to be inserted into the positioning hole and adapted to be threaded into the threaded groove so that the head of the fixing bolt 43 abuts against the first boss 41.

[0057] The number of positioning holes, threaded grooves and fixing bolts 43 can be multiple and correspond one-to-one with each other, used to lock the first boss 41 and the second boss 42, that is, to fix the end cover 3 to the mounting base 2.

[0058] By adopting the above technical solution, the end cap 3 is detachably connected to the mounting base 2 by fixing bolts 43, and the staff can easily replace or repair the roller body by removing the fixing bolts 43.

[0059] In some embodiments, please refer to the following: Figures 6 to 9 As a specific embodiment of the roller assembly provided in this application, the second boss 42 is provided with a matching groove 421 suitable for the first boss 41 to be inserted.

[0060] By adopting the above technical solution, when the end cover 3 is installed on the mounting base 2, the first boss 41 is adapted to be embedded in the alignment groove 421 on the second boss 42. The alignment groove 421 can restrict the movement of the first boss 41 relative to the second boss 42, so as to prevent the end cover 3 from shifting from the mounting base 2 during the use of the roller body 5, which would affect the normal use of the roller body 5.

[0061] In some embodiments, please refer to the following: Figures 2 to 9 As a specific embodiment of the roller assembly provided in this application, multiple brushes 6 extending toward the central axis of the through hole 31 are fixedly connected to the end cap 3 to abut against and brush the outer peripheral surface of the roller body 5.

[0062] When the roller body 5 rolls along the guide beam 8, dust and other impurities will stick to the outer peripheral wall of the roller body 5. The impurities will move with the roller body 5 to the space between the roller body 5 and the groove 21, thus affecting the normal rolling of the roller body 5 and aggravating the wear of the roller body 5. By adopting the above technical solution, multiple brushes 6 can clean the impurities on the roller body 5 during the rolling process, preventing impurities from entering the space between the roller body 5 and the groove 21, thereby improving the service life of the roller body 5.

[0063] In some embodiments, please refer to the following: Figures 2 to 9 As a specific embodiment of the roller assembly provided in this application, the end cover 3 is provided with two fixing plates 7 on the side facing away from the mounting base 2. The two fixing plates 7 are arranged side by side along the radial direction of the roller body 5 on both sides of the roller body 5, and multiple brushes 6 are respectively located on the adjacent sides of the two fixing plates 7. The end of each brush 6 abuts against the outer peripheral wall of the roller body 5. The two fixing plates 7 are detachably connected to the end cover 3 and can be connected by bolts.

[0064] By adopting the above technical solution, after multiple brushes 6 have been used for a period of time, the staff can remove and replace the worn brushes 6 by disassembling the fixing plate 7.

[0065] In some embodiments, please refer to the following: Figures 1 to 3 As a specific embodiment of the roller assembly provided in this application, each of the two side plates 11 has a protrusion 12 on an adjacent side for abutting the lower side of the flange 81.

[0066] By adopting the above technical solution, when the load on the traveling frame 9 suddenly increases and the roller assembly fails, the protrusion 12 can be adapted to connect with the lower side of the flange 81, which plays a role in preventing detachment and improving the safety of the traveling device.

[0067] In some embodiments, please refer to Figure 8As a specific embodiment of the roller assembly provided in this application, the bottom of the groove 21 is provided with a plurality of interconnected oil grooves 211, and the mounting base 2 is provided with an oil injection hole 212 that communicates with at least one oil groove 211.

[0068] By adopting the above technical solution, the operator can add lubricating oil into multiple oil grooves 211 in the groove 21 through the oil injection hole 212. Each oil groove 211 can store a portion of lubricating oil, and the lubricating oil can form an oil film in the groove 21 to lubricate the contact surface between the roller body and the groove 21, thereby reducing the friction when the roller body rotates.

[0069] In some embodiments, please refer to the following: Figure 1 and Figure 3 As a specific embodiment of the roller assembly provided in this application, an oil tank 213 for storing oil is fixedly provided on the outer side of the mounting base 2; the oil tank 213 is connected to the oil filling hole 212 through an oil supply pipe 214, and an electrically controlled valve is connected to the oil supply pipe 214. Each electrically controlled valve can be pre-programmed so that each electrically controlled valve can automatically open when the roller body rotates and automatically close when the roller body stops rotating.

[0070] By adopting the above technical solution, by setting an oil tank 213 on the outside of the mounting base 2, the electrically controlled valve on each oil supply pipe 214 can be automatically opened when the roller body rotates, realizing automatic lubrication, avoiding manual refilling by the staff, saving time and effort.

[0071] The technical solution adopted in this application also provides a traveling device, including the roller assembly proposed in any of the foregoing claims.

[0072] The beneficial effects of the traveling device provided in this embodiment are the same as those of the aforementioned roller assembly, and will not be repeated here.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
