A vertical clamping and hoisting device for cylindrical objects in narrow spaces

Abstract

The invention discloses a vertical clamping and hoisting device applied to a cylindrical object in a narrow space. The vertical clamping and hoisting device is characterized in that a support is of anannular structure, two protection plates are fixedly arranged on the two sides of the top of the support, a notch is formed in the position, below each protection plate, of the support, and supporting assemblies are arranged at notches; the outer side walls on two sides of the support each are provided with a hoisting assembly, and the two hoisting assemblies are symmetrically arranged; in each hoisting assembly, two lugs are fixed on the outer side walls of the two sides of the support, each lug is fixedly provided with a large hanging ring, a small hanging ring is arranged on the outer sidewall of the protection plate above each large hanging ring, and the two ends of a steel wire rope penetrate through the two large hanging rings and then penetrate through the small hanging rings respectively to be upwards connected to a pulley on the top of a fork frame folding arm structure. According to the vertical clamping and hoisting device, hoisting of the object is realized, the problem of height limitation in the hoisting process is solved, and the clamping and hoisting device can be installed on various mobile platforms and is high in transportability.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a vertical clamping and hoisting device for cylindrical objects in a narrow space. Background technique [0002] Clamping and hoisting of cylinders or quasi-cylindrical bodies is not a very complicated problem. The traditional hoisting method is to rely on large cranes and slings to bind hoisting. However, for some special occasions, such as inside tunnels, power plants and some indoor spaces, the environment highly limits the application of traditional hoisting methods. In addition, the traditional hoisting method often adopts the form of horizontal hoisting, which is extremely inconvenient for the vertical installation of the object, and it is also prone to rollover phenomenon due to the loose winding of the sling during the hoisting process. At the same time, because the size and shape of the hoisted objects are different, the traditional fixture can also realize the clamping of various o...

However, for some special occasions, such as the interior of tunnels, power plants and some indoor spaces, the height of the environment limits the application of traditional hoisting methods

In addition, the traditional hoisting method often adopts the form of horizontal hoisting, which is extremely inconvenient for the vertical installation of the object, and it is also prone to rollover phenomenon due to the loose winding of the sling during the hoisting process.

At the same time, because the size and shape of the hoisted objects are different, the traditional fixture can also realize the clamping of objects of various sizes wirelessly.

[0003] Because the traditional solution has certain deficiencies in terms of economy and safety, there is an urgent need for a clamping and hoisting device that is more flexible, safer and more adaptable.
