Problems solved by technology

This process requires a lot of investment, and it cannot adapt to large water level difference wharves, especially the large water level difference water level changes in artificial reservoir areas.
[0004] When floating cranes are used in the above, when the working range and lifting tonnage of the floating crane are large, the stability of the ship needs to be larger to meet the stability requirements. In this way, the larger width of the ship is wasteful. This improves the lifting efficiency of the crane with a large lifting capacity within a small working range, and objectively causes a great waste of energy consumption

Embodiment 1

[0056] see Figure 1-22 , an inland river amphibious lifting engineering ship, which includes a main hull, and the main hull includes a tail ballast tank structure 1 floating in the inland river part, and the tail ballast tank structure 1 is sequentially provided with a first empty tank 4 and The second empty cabin 5, after which the second empty cabin 5 is provided with the head ballast tank structure 6 for anchoring and supporting with the inland river bank foundation; the top of the tail ballast tank structure 1 is fixedly installed with a crane foundation Seat 8, the top of the crane base 8 is equipped with a floating crane 10, the end of the head ballast tank structure 6 is hinged with a springboard structure 8 mounted on the shore, the springboard structure 8 and the head pressure A springboard lifting device 7 for driving its lifting is installed between the loading cabin structures 6 . The lifting engineering ship with the above-mentioned structure can directly realiz...

Embodiment 2

[0066] The method for loading and unloading the inland river amphibious lifting engineering ship includes the following steps:

[0067] Step1: When unloading, anchor the head ballast tank structure 6 of the lifting engineering ship to the shore foundation, and make the entire lifting engineering ship berth with the shore foundation in a T-shape, and pass the tail ballast tank structure 1 through The cable is connected with the anchor pile on the ground to realize the anchorage of the lifting engineering ship;

[0068] Step2: Start the springboard lifting device 7, use the springboard structure 8 below the springboard lifting device 7 to support and dock it with the shore foundation, so that operators and transport vehicles can board the lifting engineering ship for operations;

[0069] Step3: drive the ship to be unloaded to the position of the stern ballast tank structure 1, and make the length direction of the hull contact with the side wall of the stern ballast tank structu...

Embodiment 3

[0074] The present invention is described further with a practical engineering example here:

[0075] Main dimensions of the ship in this embodiment:

[0076] Total length: 48m including springboard Design draft: 1.0m

[0077] Waterline length: 36.5m Navigation area: BJ2

[0078] Ship length: 36.5m Rib spacing: 0.5m

[0079] Molded width: 4.8m beam arch: 0.15m

[0080] The total width of the pontoon is 16.8m

[0081] Molded depth: 1.5m crane capacity / maximum range of work; 20 / 30m

[0082] refer to Figure 1-22 , an inland river amphibious lifting engineering ship, including a hull, below the main deck of the hull: a first ballast tank 106, a second ballast tank 107, a pump room 105, a first empty tank 4, The second empty tank 5 and the head ballast tank structure 6;

[0083] The head ballast tank structure 6 is provided with a boom base from the main deck to the bottom of the ship; the bow is hinged with a springboard structure 8, and the springboard structure 8 is hinged...

Abstract

The invention provides an inland river amphibious type hoisting engineering ship and a using method. A main ship body comprises a stern ballast tank structure floating on an inland river part, a firstempty bin and a second empty bin are arranged behind the stern ballast tank structure in sequence, and a head ballast tank structure used for being anchored and supported with an inland river bank foundation is arranged behind the second empty bin. A hoist pedestal is fixedly installed at the top of the stern ballast tank structure, a floating type hoist is installed at the top of the hoist pedestal, a spring board structure carried on the bank foundation is hinged to the tail end of the head ballast tank structure, and spring board lifting equipment used for driving the spring board structure to lift is installed between the spring board structure and the head ballast tank structure. By means of the hoisting engineering ship of the structure, loading or unloading with an incoming ship can be directly achieved, unloading or loading is carried out through the floating type hoist at the stern of the ship and by directly driving a loading truck onto the ship, a wharf transfer middle linkis omitted, and thus the loading and unloading efficiency is improved.

Description

technical field [0001] The invention relates to the field of lifting ships, in particular to an amphibious lifting engineering ship used for the boundary line between inland waters and land bases and its use method. Background technique [0002] The main lifting and loading and unloading methods of existing inland rivers, especially freight wharves with large water level drop include: floating crane, belt conveyor, wheeled crane, quayside wharf, etc. The process flow is: when loading: place of origin- Stockyard-transshipment-loading; when unloading: incoming ship-transshipment-stockyard-destination. [0003] Among them, the process of loading and unloading by floating crane is in the water environment with large water level drop. There are many links of moving the ship and anchoring and positioning, and the loading and unloading is inseparable from the above-mentioned intermediate links of transshipment. There are more process links and more pollution, and it is necessary t...
