Technical Field
The invention belongs to a construction method for installing a dust removal pipeline, and particularly relates to a method for installing a pipeline in a reconstruction project of a dust removal pipeline of an old factory building and a special hoisting device thereof.
Background
The span of the industrial factory building is large, the hoisting moment is long, and the longitudinal depth is large. The dust removal pipeline installation during the industrial factory building construction, consequently there is sufficient construction space, and the new-built factory building alternates with the installation pipeline of factory building and is under construction in step, adopts large-scale crane to hoist the pipeline and targets in place.
When the dust removal pipeline needs to be technically transformed or the dust removal pipe is additionally arranged for an completed factory building or an old factory building, only hoisting equipment can be arranged outside the factory building, but even if a large crane is used, the hoisting moment cannot meet the requirement of a large-span factory building. In addition, the space of the old factory building is small, and the pipeline cannot be directly hoisted into the factory building by the crane.
Therefore, when meeting the engineering that some factory buildings need technical transformation because of environmental protection and not meeting requirements, insisting on the difficulty of installing pipelines by adopting a large crane or a tower crane and installing the pipelines by assembly, the engineering can hardly be implemented, and the construction of the dust removal pipeline transformation of the old factory buildings becomes the technical problem in the field.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:
a method for reconstructing and installing a dust removal pipeline of an old factory building comprises the following steps:
1) laying pipeline trolley steel rails on the roof beams from outside to inside, and mounting the trolleys on the steel rails;
2) installing movable portal steel rails on two sides of the pipeline trolley steel rail, and installing the movable portal trolley on the steel rail;
3) installing a stop at the starting end of the steel rail outside the roof girder;
4) installing a winch at the end of a steel rail on the inner side of the roof girder and arranging a steel wire rope;
5) hoisting the dust removal pipeline to the pipeline trolley and fixing;
6) the pipeline trolley is pulled to a position to be installed through a winch; the movable gantry is pulled to a position where the pipeline trolley stops;
7) and a chain block is arranged on the movable door frame, the dust removal pipeline is lifted to the designed height, and the pipeline is fixed and assembled.
The method can be used for installing pipelines at the top of the old factory building and can also be used in construction environments with narrow actual space and limited hoisting of cranes, and the method is high in applicability and high in construction safety. The problem that a large crane cannot stand due to the fact that a site is narrow can be solved.
The pipeline moving and hoisting device special for the installation method comprises a pipeline trolley used for transporting the dust removal pipe and a moving portal used for lifting the dust removal pipe, wherein the pipeline trolley comprises a supporting plate and rollers, the two sides and the front end of the supporting plate are provided with binding belt fixing points, and the rear end of the supporting plate is provided with a handrail; the movable portal frame comprises four upright posts, the bottoms of the four upright posts are respectively provided with a roller, and the four upright posts are respectively arranged around the pipeline trolley; the top of the upright post is provided with a top frame, the middle of the top frame is also provided with a supporting beam, and the supporting beam is provided with a chain block and a chain block; and two ends of the supporting beam are arranged on the top frame through a sliding structure.
Furthermore, the pipeline trolley and the movable portal frame are of a movable structure which is assembled into a whole through a connecting beam.

Detailed Description
The technical scheme of the invention is clearly, specifically and completely described in the following with reference to the accompanying drawings.
With reference to the attached drawings 1-2, a method for modifying and installing a dust removal pipeline of an old factory building comprises the following steps:
1) laying a pipeline trolley steel rail 3 on the roof girder 8 from outside to inside, and installing a pipeline trolley 6 on the pipeline trolley steel rail 3;
2) installing moving portal steel rails 4 on two sides of a pipeline trolley steel rail 3, and installing moving portals 5 on the moving portal steel rails 4;
3) installing a stop at the starting end of the steel rail outside the roof girder 8;
4) the end of the steel rail is provided with a winch 1 and a steel wire rope 2 on the inner side of the roof girder;
5) the dust removal pipeline 7 is hoisted to the pipeline trolley 6 and fixed;
6) the pipeline trolley 6 is pulled to a position to be installed through the winch 1; the moving gantry 5 is drawn to the position where the pipeline trolley 6 is stopped;
