[0002] The existing unpowered side roller conveyor can greatly reduce the intensity of handling, loading and unloading, and improve work efficiency. It can be used alone or in any combination, and can be conveniently transported regardless of the weight or size of the items. For example, the applicant uses it in the factory to transport the molds used in the casting of the steel ball medium for ore dressing ball mill. When the steel ball medium is cast manually, the mold needs to be transported, and the mold is heavy and the labor intensity is too high. Therefore, an unpowered side roller conveyor is needed to assist in the transportation.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1-Figure 5 As shown, the non-powered side roller conveyor for casting ball steel ball media provided by the embodiment of the present application is now described. The non-powered side roller conveyor is mainly used by the applicant to transport molds for producing ball steel ball media for mineral processing, and of course it can also be used to transport other items, which is not limited here.

[0033] Specifically, the non-powered side roller conveyor for medium casting of ball mill steel balls for mineral processing comprises a frame 1 and a plurality of rollers 2, wherein the rollers 2 are short rollers; the length is 20-30 cm; wherein the frame 1 comprises a plurality of portal frames 11 and two parallel cross beams 12, wherein the plurality of portal frames 11 are arranged at intervals, the two cross beams 12 are arranged on the top of the portal frames 11, and a pad can be arranged on the bottom of the portal frames 11. The cross beam 12 is a rectangular hollow square steel; and the portal frame 11 is made of channel steel.

[0034] In this embodiment, a plurality of rollers 2 are provided at intervals on each crossbeam 12; the rollers 2 on two crossbeams 12 are used to transport objects such as molds.

[0035] The roller 2 includes: a mounting shaft 21, a first limiting nut 22, a bearing 23, a second limiting nut 24 and an outer sheave 25. A convex ring 211 is provided on the mounting shaft 21, one end of the mounting shaft 21 passes through the cross beam 12 and one side of the convex ring 211 abuts against one side of the cross beam 12, and one end of the mounting shaft 21 is screwed with the first limiting nut 22 to abut against the other side of the cross beam 12; the mounting shaft 21 passes through the cross beam 12, and the axial position of the mounting shaft 21 is fixed by the convex ring 211 and the first limiting nut 22, and the mounting shaft 21 does not rotate on the cross beam 12, and the mounting shaft 21 has the advantage of being easy to disassemble and assemble.

[0036] The bearing 23 is mounted on the other end of the mounting shaft 21 and its axial movement is limited by the second limiting nut 24. The bearing 23 and the cross beam 12 are respectively located on both sides of the convex ring 211. The outer sleeve 25 is arranged on the bearing 23. There is a gap between the outer sleeve 25 and the cross beam 12 to prevent the outer sleeve 25 from rubbing against the cross beam 12 when rotating. The gap width is the width of the convex ring 211. When the roller 2 is mounted on the cross beam 12, the outer sleeve 25 is located between the two cross beams 12, so that the outer sleeve 25 can be used to roll and transport the mold. The bearing 23 is a 6305-2RS bearing.

[0037] In order to ensure the cleanliness of the bearing 23, a thrust dust ring 26 is provided on the mounting shaft 21, one end of the thrust dust ring 26 abuts against the convex ring 211, and the other end abuts against the inner ring of the bearing 23. The inner wall of one end of the outer sheave 25 is in rolling contact with the thrust dust ring 26, and a cover 27 is provided on the inner wall of the other end of the outer sheave 25. The cover 27 and the thrust dust ring 26 can seal the bearing 23 in the outer sheave 25, effectively preventing dust in the working environment from contaminating the bearing 23.

[0038] Specifically, a step 251 is provided on the inner wall of the other end of the outer sleeve 25, and a groove 252 is provided on the inner wall of the other end of the outer sleeve 25. An elastic retaining ring 28 is clamped in the groove 252. The elastic retaining ring 28 abuts against the outer side of the cover 27, and the inner side of the cover 27 abuts against the step 251. The elastic retaining ring 28 is used to realize the detachable installation of the cover 27. The elastic retaining ring 28 is a C-shaped structure, specifically an elastic retaining ring 28 for the 65B hole.

[0039] In this embodiment, a second concave ring 214 is provided at one end of the installation shaft 21, and a gasket 29 is clamped on the second concave ring 214. The gasket 29 is located between the crossbeam 12 and the first limiting nut 22. A first concave ring 212 is provided at the other end of the installation shaft 21, and a stop washer 213 is clamped on the first concave ring 212. The stop washer 213 is located between the second limiting nut 24 and the bearing 23. The gasket 29 and the stop washer 213 are both used to prevent loosening.

[0040] In this embodiment, the outer side surface of the outer sleeve 25 is arranged in a stepped shape, with the outer side surface at the end away from the cross beam 12 being the lowest, and the end close to the cross beam 12 being arranged with a limiting boss 253, so that the middle of the outer side surface of the outer sleeve 25 is used to support the mold, and the middle of the inner wall of the outer sleeve 25 is used to install the shaft 21 bearing, so that the force points of the outer sleeve 25 and the bearing 23 coincide, so that the force on the bearing 23 is uniform, thereby ensuring the service life of the bearing 23, and the limiting boss 253 has a limiting effect on the mold, preventing the mold from slipping out of the outer sleeve 25, thereby ensuring that the mold is transported on the outer sleeve 25 on the two cross beams 12.

[0041] In this embodiment, two first limiting nuts 22 are provided, which have an anti-loosening function.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
