Large component roll-roll shipment method

Abstract

The invention discloses a large component roll-roll shipment method which includes the steps that (A) one side of a ship body of a shipment ship stops along a wharf; (B) supporting piers are arranged on a deck of the shipment ship; (C) a steel board is laid between the shipment ship and the edge of the wharf; (D) three rows of self-propelled modular transporters (SPMT) carry large components to the front edge of the wharf, so that the center lines of the long axes of the large components are parallel to the edge of the wharf; (E) the face of the deck of the shipment ship is a little higher than the wharf, and the first row of the SPMTs is embarked; (F) the second row of the SPMTs reaches the front edge of the wharf and is embarked; (G) when the large components weighing more than a half of the total weight of all the large components are on board, boarding is stopped, and the height difference of the face of the deck of the shipment ship and the wharf is adjusted; (H) the third row of the SPMTs is embarked; (I) the SPMTs advance to the middle of the ship; (J) the SPMTs descend and place the large components on the supporting piers. Due to the lateral roll-roll shipment mode that one side of the ship body of the shipment ship stops along the wharf, shipment time is shortened, and safety and stability of the shipment ship are greatly guaranteed.

Description

technical field [0001] The invention relates to a shipping method for shipping goods, in particular to a roll-on-roll-on-shipping method for large components. Background technique [0002] Large-scale components transported by ship are large in size (especially long in length) and heavy in weight, such as the collapsed girder sections of large bridges and anti-collision steel boxes for piers, which bring certain difficulties to shipping. [0003] Chinese invention patent application CN102837978A discloses a method of combining roll-on-roll-on and floating cranes for large components, in which a combination of roll-on-roll-on rail cars and floating cranes is used. Using this method requires at least 40 trolleys of 100 tons to be arranged for a steel box with a weight of 1750 tons. It is actually difficult to rent such a large number of trolleys, and the cost of customizing is too high; The production cost of the track beam is also very high; in addition, because of the track...

Problems solved by technology

Using this method requires at least 40 trolleys of 100 tons to be arranged for a steel box with a weight of 1,750 tons. It is actually difficult to rent such a large number of trolleys, and the cost of customizing is too high; The production cost of the track beam is also very high; in addition, because of the track, the ship deck and the wharf are always kept flush during loading in order for the trolley to board the ship smoothly. Requirements; Finally, the rental cost of large floating cranes is very high, which is not conducive to cost control

[0004] Another Chinese invention patent application CN102514953A discloses a method of roll-on and roll-on for the entire span beam section of a bridge, in which a hydraulic flatbed is used to roll-on and roll-on the ship from the stern of the ship. Components such as assembled steel sleeves and super-long shipping ships, the stern will be downwards and the bows will be tilted upwards when starting to board the ship, which will increase the difficulty of boarding and lead to poor stability of the shipping ship, and to a large extent Shipment time is too long due to tidal conditions
