Embodiment 1

[0044] The present invention is used in the construction of horizontally arranged pipelines or other equipment in electromechanical installation projects to provide construction workers with a movable work platform. Currently, it is widely used in pipeline construction and plant steel structure construction. Weld the section steel on the attachment, and then bind the springboard on the section steel, and cut off the scaffolding after use.

[0045] In view of the drawbacks of existing scaffolding in pipeline construction, this bill uses the characteristics of circular or rectangular overhead pipelines to design a movable scaffold that can walk on the pipeline, which can easily move back and forth on the narrow and long pipeline. It is safe and reliable, and can greatly improve the construction efficiency of pipeline welding, inspection, coating, heat preservation and other operations. In addition to pipeline construction, the present invention can use its substructure alone for...

Embodiment 2

[0060] The movable scaffold uses a pair of rollers 5 on the upper surface of the pipeline to realize the horizontal movement of the scaffold along the pipeline; a pair of connecting rods 6 are used to connect the two rollers 5, and a steel wire rope 3 is arranged under each of the two ends of the connecting rod 6 for suspension. The hanging cage 1 is equipped with a hand crank 2 respectively on both sides of the hanging cage 1, and the hanging cage 1 can be balanced and lifted by turning the hand crank 2.

[0061] Hanging cage 1 is made up of two halves, and is combined into one by hanging cage connecting pin 9, can make hanging cage 1 throw off from the air and pass smoothly when crossing obstacles such as pipe supports. The length of hanging cage 1 can be selected about 1 meter for use, and two people can stand simultaneously conveniently; Width should not be too large, can be about 0.6 meter, and the excessive width easily causes hanging cage to shake in the air.

Embodiment 3

[0075] Embodiment 3 is basically the same as Embodiment 1, the difference is that, as image 3 As shown, the lifting device is a chain block 10, and there are two chain blocks 10. The chain block 10 includes a chain 11 and two hooks 12 up and down. The lower hook 12 is fixed on the chain block 10 The upper and lower hooks 12 are connected to the chain hoist 10 through the chain 11, and the two chain hoists 10 are respectively hooked to the two ends of the cage 1 through the lower hook 12, and the upper ends of the chain hoist 10 are respectively hooked to two connecting rods. on the connecting hole of rod 6. The chain hoist 10 is adopted with greater load-bearing capacity and better reliability.

Abstract

The invention discloses a mobile scaffold for horizontal overhead pipeline construction and a construction method thereof and belongs to the field of mechanical and electrical installation. The mobile scaffold can horizontally move on the upper surface of a pipeline by means of a pair of idler wheels, the two idler wheels are connected through a pair of connecting rods, a steel wire rope is arranged under each of the two ends of each connecting rod to be used for hanging a cage, a hand-cranking device is installed at each of the two sides of the cage, and balancing, rising and falling of the cage can be controlled by rotating the hand-cranking devices; the cage is composed of two parts which are combined through cage connecting pins, so that the cage can be disengaged in the air so as to pass through obstacles such as a pipeline support smoothly. The mobile scaffold has the advantages that detachment is convenient, time consumption is low, installation is easy and cost is low.

Description

technical field [0001] The invention relates to the field of electromechanical installation, and more specifically relates to a movable scaffold for horizontal overhead pipeline construction and a construction method thereof. Background technique [0002] There are a large number of pipelines used in industrial production. Almost every system engineering project involves the installation of pipelines, and the pipelines in use often need to be repaired and modified. Most of these pipelines are circular pipelines laid overhead. The construction of this type of pipeline is often a high-altitude operation, and the construction area has a large span. [0003] At present, in the process of aerial welding, weld inspection and coating of pipelines, it is usually to weld section steel under the pipeline, set up a fixed springboard scaffold or use the existing platform for standing operation. Due to the need for high-altitude welding and binding and fixing in advance, this kind of sc...
