Description
Technical Field
The invention belongs to the technical field of port machinery, and particularly relates to a built-in ship-receiving lifting platform system suitable for large tidal range operation.
Background
When a large ro-ro ship is berthed to a wharf, the height of a hatch where a gangway is located can be greatly changed along with the fluctuation of tide through the whole or multiple tide periods, and a ship receiving facility needs to have the function of adjusting a ship receiving port along with the tide.
When a large-scale roll-on/roll-off ship leans against a dock, a tail springboard is generally adopted to lap the roll-on/roll-off connection bridge, and under the condition, the whole roll-on/roll-off connection bridge protrudes out of the front line of the dock, so that the safe berthing of the ship can be prevented; the rolling connection bridge facilities protruding out of the front line of the wharf can divide the front line of the wharf into a plurality of small sections with fixed length, so that large ships cannot lean against or small section shorelines cannot reasonably lean against a plurality of small ships, and the utilization rate of berths and the flexibility of scheduling are reduced.
When the side springboard is adopted to directly lap the wharf surface for operation, the height of the ship can not be adjusted in a large range because the elevation of the wharf surface is fixed; the existing method of grooving and arranging the ramp in the wharf occupies a longer width of the wharf, wastes the working space of the front edge and affects the traffic of vehicles.

Detailed Description
Referring to fig. 1 to 4, the working principle and the movement process of the present invention are as follows:
in a non-working state, the lifting platform (1) and the connecting bridge (2) are flush with the code head surface; at the moment, the locking blocks of the locking device (6) are inserted into the locking grooves (8) and can resist typhoon attack, so that the system is at a typhoon-proof position and is also at the highest ship receiving working position.
When the built-in ship-receiving lifting platform system starts to work, the hoisting lifting mechanism (5) rolls up the steel wire rope, the lifting platform (1) is lifted to enable the lower surface of the locking block to be completely separated from the bottom surface of the locking groove (8), then the locking device (6) drives the locking block to be pulled out of the locking groove (8), and the preparation work for adjusting the working position is completed.
When the built-in ship-receiving lifting platform system adjusts the working position, the hoisting lifting mechanism (5) winds up or releases the steel wire rope to drive the lifting platform (1) to vertically move up and down along the track (7) under the constraint of the guide device (4) to the locking groove (8) corresponding to the target working position, and the lower surface of the locking block is higher than the bottom surface of the locking groove (8) and the upper surface of the locking block is lower than the top surface of the locking groove (8).
After the built-in ship-receiving lifting platform system is adjusted to a working position, a locking block of a locking device (6) is inserted into a locking groove (8), then a hoisting lifting mechanism (5) releases a steel wire rope, and the lifting platform (1) is lowered to enable the lower surface of the locking block to be in full contact with the bottom surface of the locking groove (8); at the moment, the locking blocks of the locking device (6) replace the steel wire ropes of the hoisting lifting mechanism (5) to bear the load, and the adjustment and adjustment actions are completed.
