Construction site thin and long single sheet transfer process and equipment

Abstract

The invention discloses a construction site thin and long single sheet transfer process and construction site thin and long single sheet transfer process equipment. The process comprises the following steps: 1, prefabricating or transforming a plurality of portal-type supports; 2, arranging the portal-type supports by using a forklift, allowing a flat car to enter the portal-type supports and to eject the portal-type supports, and delivering the portal-type supports to a place beside the thin and long single sheets; 3, hoisting the thin and long single sheets to the top of the portal-type supports, allowing the flat car to eject the portal-type supports and the thin and long single sheets, and transporting the portal-type supports and the thin and long single sheets to a designated point; and 4, after the flat car transports the thin and long single sheets to the designated point, lowering the height of the flat car to place the portal-type supports on the ground, withdrawing the flat car from the front or back of the portal-type supports, and completing the transfer of the whole thin and long single sheets. Each portal-type support comprises a cross beam, upright posts and bases; the two ends of the cross beam area arranged on the top of the upright posts; and the bases are arranged at the bottom ends of the two upright posts respectively. According to the process, the portal-type supports are used for temporary support and transfer, so that the on-site transfer and support are combined; and the operation is simple, the sheet outlet efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to a technology and equipment for transporting a construction site with a single piece of slender structure. Background technique [0002] Offshore oil platforms and similar large-scale steel structures have densely distributed rods on the horizontal level, which mainly provide support for equipment, pipelines, and living areas. Since it is generally better to form pieces at the horizontal elevation, the rods located at the same horizontal elevation are preassembled as structural monoliths (or divided into several monoliths according to the construction capacity) during construction. After the monolithic prefabrication is completed, use a flatbed It is transported to the workshop for operations such as sandblasting and painting, and then transported to the final assembly yard, where it is installed as a whole in its final location. [0003] Slender structural single piece, which has the characteristics of large length, narrow wid...

Problems solved by technology

[0004] 1. In order to ensure the stability of the monolithic support, the temporary support needs to be welded on the monolithic piece. This additional welding work may destroy the characteristics of the base metal

[0005] 2. The temporary support in the early stage needs to be welded on the single piece, and it needs to be cut off in the final assembly, which increases the cost of welding, cutting, grinding and repainting, makes the operation procedure cumbersome, and affects the construction period

[0006] 3. Since the two ends o
