Description

Technical Field

[0001] This utility model relates to the field of sleeve alignment and assembly technology, specifically to a sleeve assembly and alignment device. Background Technology

[0002] During pipeline construction, it is necessary to align and install the sleeve and the pipeline.

[0003] Chinese utility model patent CN219543136U discloses a sleeve alignment support device. This device includes two concentrically spaced support rings that can be fitted onto the outside of a pipe. Multiple support columns, which are radially expandable and contractible, are installed circumferentially on each support ring. A telescopic connecting rod is installed between corresponding support columns of two support rings, allowing adjustment of the distance between the two support rings. When supporting the sleeve, the length of each support column needs to be adjusted individually, and the lengths of all support columns must be kept consistent according to the markings on each column. This results in cumbersome operation, long adjustment time, and reduced installation efficiency. Furthermore, while the support rings, buckles, and brackets support the pipe, their strength is relatively low. When the sleeve or pipe being aligned is large or heavy, the support rings are prone to deformation, reducing the practicality of this device.

[0004] Therefore, this utility model provides a sleeve assembly and alignment device. Utility Model Content
