Problems solved by technology

This method has the following problems: the segmented steel pipe needs to be hoisted by welding lugs; after the segmented steel pipe is hoisted in place, at least one hand chain hoist is required to cooperate with the welded steel pipe section to be accurately docked, and there are difficulties in adjusting the verticality of the steel pipe and the docking interface; After it is in place, fix it with horse plate spot welding
The traditional inversion method starts from the hanging knot binding of the segmented steel pipes, adding a chain block for adjustment when it is in place, and repeatedly adjusting the auxiliary hoist and chain block to adjust the verticality of the steel pipes, and finally spot welding with a horse plate Segmented steel pipes to be installed, the entire hoisting process has a low degree of automation, high labor intensity, low efficiency, and damage to the surface quality of the steel pipes

Embodiment Construction

[0027] refer to figure 1 , figure 2 , a method for automatic centering and inversion of shaft pipelines, comprising the steps of:

[0028] 1: Select the specifications and models of the main and auxiliary hoists according to the structure of the building, the weight and length of the vertical shaft pipeline and the weight of the separately installed segmented steel pipes; this step mainly considers two factors: rated lifting capacity and rope capacity, layout Make sure the main and auxiliary winches are threaded and wound around the steel wire ropes of the main and auxiliary winches. The steel wire ropes of the main and auxiliary winches should go around the uppermost end of the final installation position of the steel pipe.

[0029] 2: According to the steel pipe specification and model and the steel wire rope 1 specification of the auxiliary hoist, make the center limit plate 3, the automatic centering plate 5, the automatic centering lifting fixture 7, the automatic cente...

Abstract

The invention discloses a novel method for inversely installing vertical shaft pipelines. In the method, by penetrating and winding a wire rope in pipes, the subsection of a steel pipe to be installed can be very simply, conveniently and directly lifted to be automatically centered with a pipeline which is already installed, and then, the steel pipe can be welded and fixed. The method can be widely applied to installation of the vertical shaft pipelines. Compared with the traditional installing method, the novel method for inversely installing the vertical shaft pipelines has simple and convenient operation, is safer, saves the labor force, obviously reduces the labor intensity, greatly accelerates the installation progress, and achieves the effects of safety, economy, high efficiency, simplicity and convenience.

Description

technical field [0001] The invention relates to the technical field of shaft pipe installation in building construction, in particular to an automatic centering and inversion method for shaft pipes. Background technique [0002] The installation of shaft pipelines has developed from the front-mounted method to the inverted method, and the installation technology has taken a big step forward. The inversion method adopts the hoisting of the main and auxiliary hoists, the main hoist is responsible for the hoisting of the welded pipes, and the auxiliary hoist is responsible for the hoisting of the segmented steel pipes to be installed. This method has the following problems: the segmented steel pipe needs to be hoisted by welding lugs; after the segmented steel pipe is hoisted in place, at least one hand chain hoist is required to cooperate with the welded steel pipe section to be accurately docked, and there are difficulties in adjusting the verticality of the steel pipe and th...
