Embodiment Construction

[0013] Such as figure 1 As shown, the hoisting device of the chimney steel inner cylinder is composed of a base 1, a lifting seat 2, a jack 3, an anchor 5, a guard plate 4 and a wire rope 6.

[0014] Four jacks 3 are arranged between the base 1 and the lifting seat 2, and the tops of the jacks 3 support the lifting seat 2. The base 1 is a regular quadrilateral frame, the lifting base 2 is a regular octagonal frame, the inscribed circles of the base 1 and the lifting base 2 are the same, and the four cutting edges of the lifting base 2 coincide with the four cutting edges of the base 1 . The jacks 3 are evenly distributed in the middle of the four overlapping trimmings of the base 1 and the lifting seat 2 . Two hoisting holes are provided on each overlapping trimming edge, and anchorages 5 are installed at the hoisting holes, and steel wire ropes 6 are threaded through the anchorages 5. The cross-sectional structures of the base 1 and the lifting base 2 are both hollow struct...

Abstract

The invention discloses a device for lifting an inner steel barrel of a chimney and belongs to the building construction equipment. A plurality of jacks and anchors are uniformly distributed and arranged between a pedestal base and a lifting base; steel wire ropes penetrate through the anchors; the lifting base is used as a moveable hoisting platform; under the synergic effect of the jacks, the steel wire ropes are pulled by the ascending of the lifting base, so that the inner steel barrel is wholly hoisted in a balanced form by the hoisting platform; in the hoisting process, the hoisting forces are uniform, so that the safety of the hoisting and inverse suspending process of the inner steel barrel can be increased.

Description

technical field [0001] The invention belongs to building construction equipment, in particular to a hoisting device for a steel inner tube of a chimney. Background technique [0002] Tall chimneys often adopt the structural form of a combination of concrete outer cylinder and steel inner cylinder. The steel inner cylinder is often hoisted by the inversion method, that is, a lifting power device is installed on the top of the concrete outer cylinder, and the bottom of the chimney is used as the construction site. The standard section of the cylinder is welded and spliced ​​up section by section, and the steel inner cylinder is completed by splicing from bottom to top. [0003] The chimney steel inner tube is hoisted and inverted, and the power device is installed on the steel frame built on the top of the chimney. Generally, the hoisting power device uses a jack, and the steel wire rope passes through the jack to connect with the lower steel inner tube to form the entire lift...
