Problems solved by technology

Due to the limitation of the length of the boom of the floating crane, it is required to arrange it horizontally along the coastline during the growing stage, and it is necessary to call a floating crane with a large squatting position, which is very expensive, and the longitudinal loading of the roll-on-roller is largely affected by the tidal conditions. At the same time, during the segmental delivery, sometimes there are obstacles on the construction site that cannot be removed or crossed, so that the steel box girder transfer track on the shore cannot be docked with the track on the ship. Therefore, a single shipping method is adopted, which makes loading difficult big, expensive

Embodiment 1

[0013] Embodiment 1 A ship loading method combining roll-off and floating cranes for large components, the steps are as follows:

[0014] (1) Shipping preparation: dock the special girder ship on wharf 3, on which pier 3 is overlapped with trestle 2, set up pier 1 in front of wharf 3, and place the stern on pier 1 in front of wharf 3; Components are transported to wharf 3 with two large flatbed trucks, and inspected before shipment;

[0015] (2) Ro-Ro ships and floating cranes are in place: choose the appropriate tide level. When the ship is at a tide level of 2m, the deck is flush with the wharf; The flatbed truck boarded and disembarked smoothly;

[0016] Anchor positioning according to the pre-designed position; along the transverse direction of the coastline, two parallel lap platforms are arranged on the special beam carrier, and two rows of parallel tracks are laid between the lap platforms;

[0017] (3) Component ro-ro boarding: the special-purpose large flatbed truck...

Embodiment 2

[0019] Embodiment 2 A method for combining large components with ro-ro and floating cranes, the steps are as follows:

[0020] (1) Shipping preparation: dock the special girder ship on wharf 3, on which pier 3 is overlapped with trestle 2, set up pier 1 in front of wharf 3, and place the stern on pier 1 in front of wharf 3; Components are transported to wharf 3 with two large flatbed trucks, and inspected before shipment;

[0021] (2) Ro-Ro ships and floating cranes are in place: choose the appropriate tide level. When the ship is at a tide level of 3m, the deck is flush with the wharf; The flatbed truck boarded and disembarked smoothly;

[0022] Anchor positioning according to the pre-designed position; along the transverse direction of the coastline, two parallel lap platforms are arranged on the special beam carrier, and two rows of parallel tracks are laid between the lap platforms;

[0023] (3) Component ro-ro boarding: the special-purpose large flatbed truck loaded wit...

Abstract

The invention relates to a shipment method combining large constructional element rolling and floating crane, mainly relates to a rolling and floating crane combined technology during shipment, and belongs to the technical field of building material transportation. The shipment method adopts the following steps of: stopping a special beam carrying ship in a wharf, taking a large constructional element, and utilizing two large flatcars to carry the large constructional element to the wharf; selecting an appropriate tidal level, arranging two parallel overlapping platforms on the special beam carrying ship, and paving two rows of rails which are mutually parallel between the overlapping platforms; loading the special large flatcars for loading the large constructional element to a ship in a rolling way through rails, using the floating crane to lift, slowly moving to the frontage of a transport ship wharf, stopping a steel lagging box, and carrying out colligation; and transporting to the special beam carrying ship; and enabling a transport ship to move to the wharf, stopping the constructional element, and carrying out colligation and fixation. According to the invention, the large constructional element can be safely and smoothly stopped on the transport ship, the operation is easy, the shipment safety is guaranteed, the construction cost is reduced, and the existing wharfs, ships and floating cranes are fully utilized.

Description

technical field [0001] The invention relates to a method for combining roll-on-roll and floating cranes for large components, mainly relates to the combined technology of rolling-on-roll and floating cranes during the loading process, and belongs to the technical field of building material transportation. Background technique [0002] Large components generally have a large size and a large total amount, which puts forward high requirements for shipment. For such large components in the prior art, roll-on and roll-off are generally used, or they are directly hoisted on board with a large floating crane. The technology has very high requirements on the setting of lifting lugs for wharfs, transport ships, floating cranes and components. Due to the limitation of the length of the boom of the floating crane, it is required to arrange it horizontally along the coastline during the growing stage, and it is necessary to call a floating crane with a large squatting position, which i...
