Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and particularly relates to a roller device which is easy to replace and adjust the center. Background Art

[0002] In the connecting equipment of steel pipe production enterprises, roller conveyors are commonly used as a medium for transmitting steel pipes. The number of roller conveyors on each production line ranges from a few hundred to thousands. During the transmission process, steel pipes frequently roll against the rollers in the roller conveyor. After long-term use, the rollers are severely worn, which affects the surface quality of the steel pipes and requires replacement of the roller conveyor. Since most of the roller conveyors currently known are integrated roller conveyors, that is, the rollers are in an integral form with a keyway in the middle hole for installation with the roller shaft, replacing the roller conveyor requires first disassembling the reduction motor, bearing seat, bearings, etc. before replacing the rollers. This is time-consuming and labor-intensive, seriously affecting the smooth flow of production.

[0003] In the production equipment of the flaw detection area, the requirements for the centerline position of the roller are relatively strict. In particular, after the roller device has been used for a period of time, due to the gap between the roller body and the roller shaft and the wear of the bearing spacer ring, the roller body may move in the axial direction of the roller shaft, causing the centerline position of the roller device to change, which directly affects the quality of steel pipe flaw detection. The centerline position of the roller device needs to be adjusted periodically. Generally, the centerline position of the roller device is adjusted by adjusting the spacer ring in the bearing seat, which takes a long time. In addition, some roller devices cannot adjust the centerline by adjusting the bearing spacer ring due to other reasons such as the skewness of the roller seat. The roller device needs to be reprocessed, which greatly increases the difficulty of adjusting the centerline of the roller device and directly affects the smooth production.

[0004] In view of the two problems of difficulty in replacing the roller device and difficulty in adjusting the center line position of the roller device, it is urgent to improve the structure of the existing roller device to solve the above two problems, thereby improving the smooth production capacity of the equipment and reducing the labor intensity of maintenance personnel.
