Offshore auxiliary construction platform device and using method thereof

Abstract

The invention discloses an offshore auxiliary construction platform device and a using method thereof. A crane system is arranged on a movable support system; the support system comprises two parallel rail beams; a horizontal connecting beam vertical to the length direction of the rail beams is arranged between the two rail beams; the rail beams and the horizontal connecting beam have a box girder structure; two box girders are vertically connected by a diagonal bracing; a bearing platform under the rail beams is provided with a box girder support; a support system is driven to move by a travel mechanism; and the travel mechanism is that a tetrafluoro sliding plate is arranged above the box girder support, the bottom of a bottom flange of a box girder is paved with a stainless steel plate facilitating the mass movement of the platform device, and the stainless steel plate moves on the tetrafluoro sliding plate and is dragged by a traction mechanism positioned on the end parts of the rail beams. The platform device can automatically move to the next working face from one working face, avoid frequent assembly and disassembly and transportation of equipment, reduce safety risks of offshore construction, and improve the efficiency of offshore construction of pier studs.

Description

technical field [0001] The invention relates to a construction machinery equipment, in particular to a platform device suitable for auxiliary bridge cast-in-place pier construction under harsh sea conditions and a method for using the same. Background technique [0002] At present, the construction of cast-in-situ piers of the cross-sea bridge uses two kinds of equipment to assist construction, one is the auxiliary construction of the crane ship, and the other is the auxiliary construction of the steel platform. [0003] A crane ship, also known as a multi-purpose operation ship, refers to a large flat barge with lifting equipment on the deck. The crane ship is anchored between the two piers. The cabin is used as the front office and living place for construction workers, and the deck is used as a storage place for temporary materials such as steel bars and formwork. The ship's crane is used as a vertical transportation tool for materials and machinery; the ship is equipped...

Problems solved by technology

[0005] However, during the construction of cast-in-place pier columns at sea, the crane ship is affected by sea tides, wind waves and typhoons, especially in the open sea, which makes it difficult for the ship to stand stably, and the crane above it is difficult to operate normally, and the construction efficiency is low , the safety risk is relatively large; the steel platform changes offshore construction into land construction, but because the steel platform cannot be moved flexibly, each pier needs to be erected and dismantled, the platform uses a large amount of steel, the construction period is long, and the construction efficiency is low ,higher cost

Therefore, the above two auxiliary construction methods have certain limitations, and the comprehensive performance is not good.
