Abstract

The utility model relates to a combined floating crane for mud flats. One end of a cargo boom on hoisting equipment is hinged with a rotating disc; the lower end of a rotating column is connected with the rotating disc; the rotating disc is connected with a cross beam; the cross beam is connected with an inclined support; the upper end of the cargo boom and the rotating column rotate together through movement of pulleys and steel wire ropes driven by a winch on a transmission device; a bearing main body device comprises a ship body and a bracket; the ship body consists of boat sections and water distributing sections which are assembled together respectively through fasteners; and after the ship body is assembled, a cross brace is fixed on a deck of the ship body, the upper end of the bracket and the rotating disc are connected to form a whole body through a fastener, the lower end of the bracket is fixed on the cross brace, and a bollard and an anchoring machine are fixed on the deck of the ship body. The combined floating crane for mud flats has the advantages that the ship body is of an assembled or buoyancy tank split structure, so that the transportation is facilitated; the depth of immersion is less than 1.0 meter, so that the ship body stays on the mud flat stably; the whole structure is high in stability and strength, and the wind-resistant capability is high enough to resist wind power not less than level 5; a crane component is of a detachable split type, and the split mounting is simple and quick; and the combined floating crane is special hoisting equipment for shallow water operation.

Description

Beach compound type crane barge

Technical field

The utility model relates to a kind of crane barge, particularly relates to a kind of beach compound type crane barge that is used for the shallow water special operation.

Background technology

As everyone knows, in China's Coastal Areas, particularly there is a large amount of beach in the marine site, Bohai Sea Gulf, and these regional depth of waters are more shallow, and depth of water less than is 2.5 meters during high tide level, almost all exposes more than the water surface during low tide level (LWL); At present, lifting boats and ships both domestic and external and equipment almost are exactly blank in this field; Reason such as dark and hull structure is difficult to sail into crane ship owing to drinking water, must be by excavating means such as navigation channel, but expense is high; Ancillary method such as use the land weight-lifting equipment also to need to build bridge or to pave the way is so it is huge to drop into appropriate litigation fees in advance.

Summary of the invention

The utility model provides a kind of beach compound type crane barge that is used for the shallow water special operation for solving the technical matters that exists in the known technology.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: it comprises weight-lifting equipment and driving device, it is characterized in that:

⑴. weight-lifting equipment: it comprises crane arm, rotary column, rotating disc, diagonal ligament, crossbeam and driving device, crane arm one end and rotating disc are hinged, the rotary column lower end is connected with rotating disc, rotating disc is connected with crossbeam, crossbeam is connected with diagonal ligament, pulley and steel rope and rotary column rotation that the upper end of crane arm drives by the winch on the driving device, pulley, steel rope link to each other with the crane arm upper end with rotary column;

⑵. the carrying agent set: it comprises hull and carriage, and hull is made up of with water separation section the boat joint, and they fit together respectively with fastener; After the assembling, be fixed with stull on deck in ship structure, the upper end and the rotating disc of carriage link into an integrated entity with fastener, and the lower end is fixed in the stull, is fixed with checking bollard and windlass on the deck in ship structure.

The utility model can also be by the following technical solutions:

Described boat joint is a cavity with water separation section inside;

Being connected and can adopting deck in ship structure and being connected of stull and weld or the fastener connection of described boat joint and water separation section.

Advantage and the good effect that the utlity model has are: hull structure adopts assembly type or buoyancy tank split type, so that adopt water route or land transport mode; Draft can be lower than 1.0 meters, and hull seat beach is steady; Integral structure has cooresponding stability and intensity, and wind loading rating is not less than 5 grades of wind-force; The hoisting crane primary member also adopts detachable pin-connected panel; The integral structure assembly unit is simple, quick; " beach compound type crane barge " is the Special Hoisting Equipment of carrying out under the shallow water special operation environment.

Among Fig. 1-Fig. 5: 1. crane arm, 2. rotary column, 3. rotating disc, 4. diagonal ligament, 5. crossbeam, 6. driving device, 7. carriage, 8. boat joint, 9. water separation section, 10. stull, 11. checking bollards, 12. windlass.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows, see also Fig. 1-Fig. 5.

As shown in Figure 1 and Figure 2:

⑴. weight-lifting equipment: it comprises crane arm 1, rotary column 2, rotating disc 3, diagonal ligament 4, crossbeam 5 and driving device 6, crane arm 1 one ends and rotating disc 3 are hinged, rotary column 2 lower ends are connected with rotating disc 3, rotating disc 3 is connected with crossbeam 5, crossbeam 5 is connected with diagonal ligament 4, the pulley of crane arm 1 upper end captive joint, steel rope and rotary column 2 are by pulley and the steel rope and rotary column 2 rotations of the drive of the winch on the driving device 6;

⑵. carrying agent set: as Fig. 2-shown in Figure 5: it comprises hull and carriage 7, hull is made up of with water separation section 9 boat joint 8, and boat joint 8 is a cavity with water separation section 9 inside, and the hull of hull is a boat joint 8, fore is a water separation section 9, and they fit together respectively with fastener; After the assembling, on deck in ship structure, be fixed with stull 10 with fastener (or welding), the upper end of carriage 7 and rotating disc 3 usefulness fasteners (or welding) link into an integrated entity, the lower end is fixed in the stull 10 with fastener (or welding), essential strict seal when described fastener connects, be fixed with checking bollard 11 and windlass 12 on the deck in ship structure, after four windlass cast anchor with hull steadily the seat on the shoal, described carriage is used for regulating and satisfying the sling height of hoisting crane, adopt truss structure, be convenient to the increase and decrease height.
