Limiting-fixing hoisting device for steel pipe

Abstract

The invention relates to the field of hoisting equipment for steel pipes, and specifically relates to a limiting-fixing hoisting device for a steel pipe. The limiting-fixing hoisting device for the steel pipe comprises a device main body, wherein reinforcing plates are movably installed at the two sides in the device main body, and a steel pipe fixing device is movably installed at the lower end in the device main body. An elastic rotary shaft is fixedly installed between the steel pipe fixing device and a limiting-clamping plate, a baffle is fixedly installed at the outer side of the steel pipe fixing device, and the limiting-clamping plate is enabled to rotate outwards under the action of the elastic rotary shaft until the limiting-clamping plate makes contact with the baffle; when the steel pipe fixing device is driven to rotate, through formation for a limiting groove in the outer side of the steel pipe fixing device and through semi-arc-shaped configuration for the limiting-clamping plate, the limiting-clamping plate is enabled to receive the steel pipe at the lower end of the device main body into the limiting-clamping plate and then to be driven towards the interior of the steel pipe fixing device, and then form a complete circle with the limiting groove to carry out limiting-fixing on the steel pipe which is received inside, so that the safety during hoisting for the steel pipe is improved.

Description

technical field [0001] The invention relates to the field of steel pipe hoisting equipment, in particular to a steel pipe limit fixed hoisting device. Background technique [0002] Steel structure building is one of the main building types at present. Because steel has high strength, light weight, good overall rigidity and strong deformation ability, it is especially suitable for building long-span, super high and super heavy buildings; material homogeneity With good isotropy and isotropy, it is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; its high degree of industrialization can be Specialized production with a high degree of mechanization. Steel structures such as steel plates and steel pipes have a wide range of applications. In factories, steel structure products ne...

Problems solved by technology

[0003] The existing steel pipe hoisting needs to manually tie the steel pipe with a rope, and then hang the hook on the rope to hoist the steel pipe, which makes it time-consuming and laborious, and the fixation is not firm enough. When the steel pipe is tilted during transportation, it is easy to cause the steel pipe to fall off from the rope, causing a great safety hazard
