Pipeline lifting sling

Abstract

The invention relates to a pipeline lifting sling. The pipeline lifting sling comprises a plurality of bracket bodies. Each bracket body comprises two vertical rods arranged symmetrically. Every two vertical rods are connected through a supporting rod with scales, one of the vertical rods is fixedly connected with one end of the supporting rod, and the other vertical rod is connected with the supporting rod in a sliding mode. Telescopic cross rods are arranged above the supporting rods and arranged between the two vertical rods. The cross rods are connected with the two vertical rods in a sliding mode in the vertical direction. Slip-resistant layers are arranged on the inners sides of the two vertical rods and on the lower surfaces of the cross rods. The bracket bodies are connected through connecting rods which are arranged above the cross rods. The cross rods are connected with the connecting rods in a sliding mode. Lifting hooks are arranged on the connecting rods. According to the pipeline lifting sling, the problems that pipelines are liable to fall down, the lifting quantity is limited each time in the lifting process and the function is simplex are solved.

Description

technical field [0001] The invention relates to a hanger, in particular to a pipeline hanger. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] The connection method between pipes, pipe joints, valves and inlet and outlet pipes on the equipment is determined by the nature of the fluid, pressure and temperature, as well as the material, size and installation place of the pipes. There are mainly threaded connec...
