Embodiment 1

[0041] Embodiment 1: Use only the first lifting plate 6 for underwater operations, control the first push plate 107 to retract the first insertion bolt 106, so that the first lifting plate 6 and the main deck 1 are disconnected from the rigid connection, and then the second sea valve 602 Partially open, so that the external water flows into the two ballast tanks 601, at the same time, the two slewing cranes 4 corresponding to the first lifting plate 6 of this operation slowly release the sling 407, and cooperate with the first lifting plate 6 to sink , by controlling the water intake of the two ballast tanks 601 and the length of the sling 407 of the slewing crane 4 to adjust the hovering depth of the first lifting plate 6 in the water, so as to realize the flexible control of the depth of the first lifting plate 6, when the first After the lifting plate 6 completes the work in the water, the second compressed air storage tank 605 feeds compressed air into the ballast tank 601,...

Embodiment 2

[0042] Embodiment 2: Use two first lifting plates 6 to carry out underwater operations at the same time, the first docking blocks 611 of the two first lifting plates 6 are released from the first docking groove 101 in the main deck 1, and the two first lifting plates 6 The plate 6 is disconnected from the main deck 1, and then the ballast tanks 601 of the two first lifting plates 6 enter water through the second sea valve 602 to drive the first lifting plate 6 to sink slowly, and at the same time, the slewing crane 4 releases the sling 407 to cooperate The first lifting plate 6 sinks, and the two first lifting plates 6 can sink to the same water depth or sink to different water depths for simultaneous operation, and the electric propeller 609 that is arranged at the bottom of the first lifting plate 6 during underwater operations After work, the posture and position in the water of the first lifting plate 6 can be properly adjusted. After the operation is completed, the two fir...

Embodiment 3

[0043] Embodiment 3: Only use the second lifting plate 6 to carry out underwater work, control the second hydraulic push rod 112 to retract the second insertion bolt 110, so that the first lifting plate 7 is released from the rigid connection with the main deck 1, and the first lifting plate 7 and the main deck 1 are released from the rigid connection. The two slewing cranes 4 corresponding to the second lifting plate 7 slowly release the sling 407, cooperate with the second lifting plate 7 to sink, and adjust the hovering of the second lifting plate 7 in the water by controlling the length of the sling 407 of the slewing crane 4 Depth, in order to realize the flexible control of the depth of the second lifting plate 7, when the second lifting plate 7 completes the underwater operation, the two slewing cranes 4 recover the sling 407, the second lifting plate 7 slowly rises to the water surface, and then the second lifting plate The plate 7 inserts the second docking block 705 i...

Abstract

The invention discloses an underwater operation lifting platform. The platform comprises a main deck and a cabin, the cabin is arranged at the bottom of the main deck, a passenger compartment is arranged on the main deck, four rotary cranes and four pile legs penetrating through the main deck are arranged at the top of the main deck, symmetrical first lifting plates are arranged on the two sides of the main deck, symmetrical second lifting plates are arranged on the other two sides of the main deck, the first lifting plates and the second lifting plates can be separated from the main deck, the first lifting plates and the second lifting plates can be mutually connected through inserting blocks arranged at the two ends of the second lifting plates, and therefore, the first lifting plates or the second lifting plates can be driven to independently lift in water according to different requirements, or the first lifting plates and the second lifting plates are connected and then used at the same time. The lifting platform can adapt to different working conditions and is more flexible to use and wider in use range.

Description

technical field [0001] The invention relates to the technical field of underwater operation equipment, in particular to a lifting platform for underwater operation. Background technique [0002] Due to the continuous development of water transportation and the construction requirements of infrastructure, the demand for underwater operations is increasingly strong, such as underwater pipeline layout, maintenance, underwater detection, rescue and salvage, etc. At present, the general underwater operations use small professional equipment, but The use of these small devices often has high cost of use, small loads, poor coordination and stability, and cannot meet the safety requirements of harsh underwater environments. Therefore, it is necessary to provide a device that can meet the needs of various underwater operations, and has the characteristics of a large operating range, integrated functions, and the ability to move autonomously. Contents of the invention [0003] In o...
