Description

Technical Field

[0001] This utility model relates to the field of steel pipe conveyor roller technology, specifically to a cold-drawn steel pipe conveyor roller. Background Technology

[0002] In the production and processing of cold-drawn steel pipes, the pipe conveying is a crucial link in the entire production process. An efficient, stable, and precise conveying system ensures the smooth transfer of steel pipes between different processing steps, guaranteeing the continuity of the production line and the consistency of product quality. Traditional conveyor roller conveyors generally include a base, a motor fixed on the upper side of the base, a drive shaft fixed at the output end of the motor, conveyor rollers fixed on the outside of the drive shaft, and bearing seats at both ends of the drive shaft. When arranging them, several conveyor roller conveyors need to be located on the same straight line to facilitate straight transportation in the pipeline. However, this installation method requires extremely high precision. It is essential to ensure that several conveyor rollers are aligned in a straight line. If there is a deviation in the position between the conveyor rollers, some steel pipes may fail to make contact with the conveyor rollers, leading to conveying failure and affecting the conveying efficiency. Furthermore, the top of the existing conveyor rollers is generally open. When conveying thinner steel pipes, if the drive shaft experiences transmission instability, it may cause the steel pipe to become unstable and detach from the rollers. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing conveyor rollers need to be precisely and linearly arranged, otherwise the steel pipes may not be able to contact the rollers, leading to conveying failure. Furthermore, when conveying thin steel pipes through an open top, the pipes are prone to detachment due to unstable transmission.

[0004] To solve the above problems, the technical solution adopted by this utility model is a cold-drawn steel pipe conveyor roller, including: a base, a driving mechanism fixed on the upper side of the base, a transmission shaft fixed at the output end of the driving mechanism, a number of connecting protrusions fixed on the outside of the transmission shaft, and a conveying roller sleeved on the outside of the transmission shaft. The upper side of the base is provided with a limiting mechanism, which includes a pair of symmetrically fixed support frames. A support plate is fixed at the top of the support frame. An adjusting bolt is rotatably connected to the side of the support plate by a thread. A connecting plate is rotatably provided at the bottom of the adjusting bolt. A limiting groove is opened on the lower side of the connecting plate. A limiting plate is slidably provided in the limiting groove. Several balls are evenly ball-connected on the lower side of the limiting plate.

[0005] As a further embodiment of this utility model, both ends of the transmission shaft are provided with bearing seats fixed on the upper side of the base, which facilitates the stable rotation of the transmission shaft.

[0006] As a further embodiment of this invention, the length of the drive shaft is greater than the length of the conveying roller, which allows the conveying roller to slide slightly along the drive shaft to facilitate compensation for installation errors.

[0007] As a further embodiment of this utility model: the lower side of the limiting plate is an arc surface, which is convenient to adapt to the arc surface of the steel pipe.

[0008] As a further embodiment of this utility model, both ends of the connecting plate are limited and set inside the support frame to prevent the connecting plate from rotating.

[0009] Compared with the prior art, the advantages of this utility model are as follows: This application adds a limiting mechanism, which can limit the position of the steel pipe through the limiting plate to ensure the stable conveying of the steel pipe. In addition, the length of the conveying roller is slightly shortened, which allows the conveying roller to slide slightly on the outside of the drive shaft. This can make the straight installation of the base less precise, thereby reducing installation efficiency. The slight sliding between the conveying roller and the drive shaft can compensate for the partial offset of the base, thereby ensuring the conveying of the steel pipe. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0017] Combined with appendix Figure 1 , 2 It can be seen that it includes: a base 1, a drive mechanism fixed on the upper side of the base 1, a drive shaft 2 fixed at the output end of the drive mechanism, bearing seats 11 fixed on the upper side of the base 1 at both ends of the drive shaft 2 to facilitate the stable rotation of the drive shaft 2, several connecting protrusions 3 fixed on the outer side of the drive shaft 2, and a conveying roller 4 sleeved on the outer side of the drive shaft 2. The length of the drive shaft 2 is greater than the length of the conveying roller 4, which allows the conveying roller 4 to slide slightly along the drive shaft 2 to facilitate the compensation of installation errors. Combined with appendix Figure 1 , 3 4. It can be seen that a limiting mechanism is provided on the upper side of the base 1. The limiting mechanism includes a pair of symmetrically fixed support frames 5. A support plate 6 is fixed at the top of the support frame 5. An adjusting bolt 7 is rotatably connected to the side of the support plate 6 by a thread. A connecting plate 8 is rotatably provided at the bottom of the adjusting bolt 7. Both ends of the connecting plate 8 are limited and set inside the support frame 5 to prevent the connecting plate 8 from rotating. A limiting groove is opened on the lower side of the connecting plate 8. A limiting plate 9 is slidably provided in the limiting groove. The lower side of the limiting plate 9 is an arc surface to adapt to the arc surface of the steel pipe. Several balls 10 are evenly ball-connected on the lower side of the limiting plate 9.

[0018] The working principle of this utility model is as follows: When transporting steel pipes, the steel pipes are first hoisted onto the upper side of the conveying rollers 4 using hoisting equipment. Then, the sliding limit plate 9 is positioned above the steel pipe. Next, the adjusting bolt 7 is rotated so that the ball bearings 10 can contact the steel pipe, thereby ensuring stable transport of the steel pipes. During the transport process, the conveying rollers 4 can make slight displacements relative to the drive shaft 2 to compensate for slight errors caused by the bases 1 not being on the same straight line, thus ensuring stable transport of the steel pipes.

[0019] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
