Problems solved by technology

[0006] Based on the above advantages, the poles can be used for vertical transportation of equipment in high-rise buildings, but most of the hinge supports of existing poles are fixedly connected with embedded parts in the ground of high-rise buildings by bolts. The location selection range in high-rise buildings is small, which cannot adapt to complex and changeable construction sites, and the installation of embedded parts is not only cumbersome in construction, but also causes damage to the ground of the building

Abstract

The invention provides a movable independent derrick mast lifting device and a lifting method of the lifting device. The movable independent derrick mast lifting device comprises a derrick mast stand column, a pin shaft and an embedded part. A base is arranged at the bottom of the derrick mast stand column. A pin shaft hole is formed in the base. An installation plate is arranged at the position, corresponding to the base, of the top end of the embedded part. A pin shaft hole corresponding to the pin shaft hole in the base is formed in the installation plate. The derrick mast stand column is installed on the embedded part in the manner that the pin shaft penetrates the pin shaft hole in the base and the pin shaft hole in the installation plate. By means of the structure, the performance that the lifting efficiency is high, manufacturing cost is low, demounting is convenient and use is flexible is achieved, and in addition, safe and reliable lifting work can be achieved on components within 10 tons in areas which have hidden environments or have small and narrow space or cannot be covered by a tower crane.

Description

technical field [0001] The invention belongs to the technical field of building hoisting and hoisting equipment, and in particular relates to a movable independent pole hoisting device and its Lifting method. Background technique [0002] With the development of the national economy, there is a strong demand for building more and larger buildings with large spaces and super-large spaces such as sports, leisure, exhibitions, airports, hangars, etc. This kind of building form is generally a space steel structure, and the structure type can be divided into grid frame (light steel), space truss (heavy steel) and so on. These buildings usually have the characteristics of large span, unique shape, complex stress and regional symbolic significance after completion. [0003] In the installation project of such large-span building components, general-purpose hoisting equipment, such as crawler cranes, tower cranes, gantry cranes or truck cranes, are widely used for component hoisti...
