Large-tonnage single-girder horizontal sling for hoisting rocket bodies

Abstract

The invention discloses a large-tonnage single-girder horizontal sling for hoisting rocket bodies. The large-tonnage single-girder horizontal sling for hoisting the rocket bodies comprises a hoisting girder, dual-hook hoisting assemblies, single-hook hoisting assemblies and rock body connection assemblies; a first dual-hook hoisting connection hole and a second dual-hook hoisting connection hole are symmetrically formed in the two ends of the hoisting girder; a first single-hook hoisting connection hole and a second single-hook hoisting connection hole are symmetrically formed in the two sides of the center axis of the hoisting girder; and a first hoisting point connection hole, a second hoisting point connection hole, a third hoisting point connection hole, a fourth hoisting point connection hole, a fifth hoisting point connection hole and a sixth hoisting point connection hole are sequentially formed in the portion, in the horizontal direction and located on a connection line of the first dual-hook hoisting connection hole and the second dual-hook hoisting connection hole, of the hoisting girder. The large-tonnage single-girder horizontal sling for hoisting the rocket bodies has the beneficial effects of being simple in structure, safe, reliable and easy and convenient to operate. By means of the large-tonnage single-girder horizontal sling for hoisting the rocket bodies, the rocket bodies can be hoisted through a single vehicle or two vehicles, the requirement of the sling for the environment of a workshop is lowered, and multifunctional and multi-state application can be achieved.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a large-tonnage single-girder horizontal hoisting tool which is used for hoisting an arrow body and is suitable for both single and double vehicles. Background technique [0002] In the field of aerospace, the launch vehicle often needs to be hoisted and reloaded during the production and assembly process. At present, this field mainly uses a single crane with a single beam spreader for hoisting operations. However, with the development of technology and the development of new products, for some solid launch vehicles, their mass and size have greatly increased compared with existing rockets, and the first-stage rocket body with the largest mass is as high as 40 tons. This puts forward higher requirements on the rated load, self-weight and size of the rocket body spreader, and exceeds the capacity range of the spreader used to lift previous types of rocket products. At the same time, due to ...

Problems solved by technology

[0004] In order to solve the problem that the current rocket body spreader in the prior art cannot meet the hoisting requirements of the larger rocket body due to its small rated load, and because of its high requirements for the plant environment, a single crane will not be able to complete the task. For the problem of hoisting the rocket body, the present invention provides a large-tonnage single-girder horizontal hanger for hoisting the rocket body, including a hanging beam, a double-hook lifting assembly, a single-hook lifting assembly and an arrow body connecting assembly, wherein the hanging beam Both ends of the beam are symmetrically provided with a first double-hook lifting connection hole and a second double-hook lifting connection hole, and both sides of the central axis of the hanging beam are symmetrically provided with a first single-hook lifting connection hole and a second single-hook lifting connection hole;
