[0024] Specifically, in the process of conveying cold-rolled ribbed steel bars, a high-alloy wear-resistant precision pipe sleeve 1 is used as a carbon steel pipe skin sleeve on the pipe body 3. This sleeve has a mirror surface finish, which can greatly reduce friction and thus significantly reduce wear. When it is necessary to install or replace the sleeve 1, it can be hung on the inside of the reserved hole 2 with a hook, so that the sleeve 1 can be easily pulled out from the outside of the pipe body 3. When assembling the sleeve 1, it can be very convenient to install as long as the limiting block 4 is aligned with the inside of the limiting groove 5. This simple replacement design has very outstanding economy and practicality. It not only reduces material costs and improves the cost performance of equipment, but also makes equipment maintenance and replacement more convenient, reduces the time required for equipment maintenance and replacement, and thus improves production efficiency. In the production of cold-rolled ribbed steel bar welded mesh, this design can ensure the stable operation of the longitudinal reinforcement wire feeding mechanism, providing a strong guarantee for improving product quality and production efficiency.

[0025] Referring to Figs. 1-3 , the disassembly and assembly assembly is arranged at the outer side of both ends of the sleeve 1, which is used for quickly assembling and disassembling the pipe body 3.

The outer side of the two assembly sleeves 7 is provided with a rotating shaft 8, which is rotationally connected through the rotating shaft 8. The inner side of the assembly sleeve 7 is provided with an assembly groove 9, and the inner wall of the assembly groove 9 is provided with a clamping block 10. The outer side of the pipe body 3 is in sliding connection with the inner side of the assembly groove 9, and the outer side of the clamping block 10 is clamped in the inner side of the clamping groove 6. This clamping structure ensures the stability of the pipe body 3 during use. The outer side of the assembly sleeve 7 is rotationally connected with an L-shaped movable block 11, and the outer side of the other assembly sleeve 7 is fixedly connected with an L-shaped positioning block 12 and a magnetic block 13. The outer side of the L-shaped movable block 11 is attached to the outer side of the L-shaped positioning block 12, and the L-shaped movable block 11 is attached to the magnetic block 13 through magnetic attraction. When it is necessary to disassemble the pipe body 3 to replace the sleeve 1, first rotate the L-shaped movable block 11 to separate the outer side of the L-shaped movable block 11 from the magnetic block 13 and release the restriction on the L-shaped positioning block 12. Then rotate the upper assembly sleeve 7, so that the pipe body 3 is exposed. The edge of the clamping block 10 in the upper assembly sleeve 7 is treated to facilitate the disengagement of the clamping groove 6. Then the pipe body 3 can be easily removed from the assembly sleeve 7. This disassembly method is more convenient than the traditional bolt fastening, saving time and labor costs.

[0027] Working principle: when the pipe body 3 needs to be disassembled to replace the pipe sleeve 1, the L-shaped movable block 11 can be rotated to separate it from the outer side of the magnetic block 13, and the restriction on the L-shaped positioning block 12 is released, then the upper assembly sleeve 7 can be rotated to expose the pipe body 3, the edge of the clamping block 10 in the upper assembly sleeve 7 is treated, which can be conveniently disengaged with the clamping groove 6, then the pipe body 3 can be easily taken out from the assembly sleeve 7, which is more convenient than the traditional bolt fastening when disassembled.

[0028] In addition, when conveying cold-rolled ribbed steel bars, the pipe sleeve 1 made of high-alloy wear-resistant precision pipe material is used as a carbon steel pipe skin sleeve on the pipe body 3, and the mirror surface finish greatly reduces the friction force and thus reduces wear, when the pipe sleeve 1 needs to be installed and replaced, it can be hung in the reserved hole 2 on the inner side, which can easily pull the pipe sleeve 1 out of the outside of the pipe body 3, when assembling the pipe sleeve 1, the limiting block 4 can be aligned with the inner side of the limiting groove 5, which can facilitate installation and replacement, and has very good economy and practicability.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacement of some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
