Description

Technical Field

[0001] The utility model relates to the technical field of pipeline hoists, in particular to a safety protection device for pipeline hoists. Background Art

[0002] For large-sized pipelines, pipeline lifting at construction sites generally uses guide chains to lift the pipelines to a predetermined height, which has the following problems: the guide chain needs a fixed point, which is generally fixed on the floor slab, damaging the floor slab; the review of the guide chain fixing point has not been professionally calculated, and workers generally fix it based on experience, which is easy to fall off and cause safety accidents; large pipeline lifting is generally not completed by two workers, and more workers are required to participate. There are finished pipeline hoists on the market, but the pipeline bracket is steel, which cannot ensure the stability of the pipeline and the pipeline is easy to roll down; and the vertical bracket of the hoist is too high to lift the pipeline to a position close to the top plate, but the existing pipeline hoists still have certain problems when in use:

[0003] For example, a pipeline hoist with publication number CN211895867U has the following technical solution: it includes a base and universal wheels arranged at the four corners of the bottom of the base, a horizontal beam is arranged in the middle of the base surface, and a sleeve is symmetrically and vertically arranged on both sides of the middle of the beam, a support rod is fixed in each sleeve, and a plurality of connecting rods are arranged between the two support rods from top to bottom, a fixing device connected to the top of the support rod is arranged on the base on the rear side of the beam, a fixed sleeve is symmetrically arranged in the middle of the two support rods, and a sliding sleeve is arranged on the front side of the two fixed sleeves. It has a reasonable structural design and is easy to operate. The position of the hoist can be adjusted at any time according to the installation position of the pipeline. It has strong applicability and does not require the installation of a fixed frame, which greatly saves construction costs and shortens construction time. During the lifting process of the pipeline, there is no need to hold it by hand to prevent the pipeline from rotating horizontally during the suspension process, which is more convenient for the installation of the pipeline. However, the existing pipeline hoist has a weak fixing effect while supporting the pipeline, and the pipeline is prone to sliding and falling off. In addition, the stability of the bottom of the pipeline hoist cannot be guaranteed during the lifting process of the pipeline, and it is easy to tip over, posing a safety hazard.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design was carried out based on the original pipeline hoist. Utility Model Content
