Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline hoisting equipment, specifically, it relates to a scratch-resistant hydrogen pipeline hoisting device. Background Technology

[0002] In pipeline installation projects, it is often necessary to hoist lightweight pipeline steel plates.

[0003] The utility model disclosed in CN207090837U describes a mobile lightweight lifting device, comprising a base, a winch, a lifting column, a lifting crossbar, and a counterweight column. The base has four lockable casters for horizontal movement. A winch and matching fixed pulleys are mounted on the base. The winch serves as the lifting machinery, with its wire rope passing over the fixed and movable pulleys and connecting to the hook. The winch winds the wire rope to lift the object to the installation location. A counterweight column is located at the rear of the base; its length is adjustable, and a screw adjustment device is installed at the bottom to ensure reliable support against the upper floor slab, serving to lift and stabilize the device and prevent overturning. The lifting column is a height-adjustable combination column, fixed with bolts after adjustment to a suitable height. The lifting crossbar is also an adjustable combination crossbar, fixed with bolts after adjustment to a suitable length. This invention features a lightweight, simple, and easy-to-move device for hoisting items, reducing the workload of hoisting electromechanical pipelines and equipment. However, the aforementioned patent still has the following problems: Traditional hoisting methods typically use ordinary hooks to directly hook the pipeline steel. Because the hook is in direct contact with the surface of the pipeline steel, the edges or rough areas of the hook can easily scratch the surface of the pipeline steel during the hoisting process. Scratches not only affect the appearance of the pipeline steel, but also reduce its corrosion resistance and shorten its service life. In some projects with high requirements for pipeline surface quality, such as chemical and petroleum industries, scratches may lead to serious safety hazards and economic losses.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content
