Large-sized stand column extra-column construction platform device and method

Abstract

The invention provides a large-sized stand column extra-column construction platform device comprising a tower cylinder. Construction platforms are symmetrically sleeved on the tower cylinder and a cross beam is fixedly mounted at the upper end of the tower cylinder; hoisting pulleys are symmetrically arranged at two ends of the cross beam; a fixed guide pulley and a winch are arranged at two sides of the tower cylinder along the direction of the cross beam; and a steel wire rope of the winch is connected with the construction platforms through a pulley group. With the adoption of the structure, the structure of a construction auxiliary device and a construction method are simplified and constructors can relatively conveniently carry out back chipping on stand column extra-column welding back seams and welding on the back seams, and work including welding seam flaw detection, corrosion resistance, quality inspection and the like also can be realized; and equipment including a welding machine and the like are convenient to move, the construction cost is reduced, the stressing structure of a stand column is optimized, and the safety of a whole lifting device is greatly improved.

Description

technical field [0001] The invention relates to the field of large-scale column construction, such as the column for the feed line of the tower belt machine, a construction platform suitable for welding, anti-corrosion, inspection, demolition, etc. A construction platform device and method thereof. Background technique [0002] In the concrete pouring construction of large-scale hydropower and water conservancy projects, the tower belt machine feeding line system is often used. The feeding line is composed of belt racks and belt conveyors arranged continuously on several tower columns, which can realize the continuous conveying and pouring of concrete from the mixing building to the pouring warehouse. Among them, the column structure is made of several tower tubes connected by welding or bolts, some of which are as high as 100 meters. In the structure with welded connection between the towers, it is necessary to carry out the back seam cleaning and welding back seam on the...

AI Technical Summary

Problems solved by technology

Due to the high column and many working procedures, the construction safety of the high-bracket frame is poor, and the transfer of welding machines and other equipment is also very troublesome.

[0003] Chinese patent 95237557.5 discloses a hoist. There is a working platform sleeve frame at the upper end of the column. The sleeve frame is equipped with a rotatable pole hoisting standard joint. The lifting platform is slidingly matched with the column. , the lifting platform is located on one side of the column, so the stability of the column must rely on the outer wall of the building, that is, the force of the column is unbalanced, and it is not suitable for construction occasions that are only used for the construction of the outer wall of the column.

Moreover, a separate guide rail needs to be set between the column and the working platform, and it is not suitable for the working conditions of the construction work on the outer wall of a single column.
