Description

Technical Field

[0001] The utility model relates to the technical field of deployment and recovery of marine equipment, in particular to an underwater deployment anti-swing swing frame device. Background Art

[0002] The LARS (Launch and Recovery System) is usually required for the deployment and recovery of remotely operated vehicles (ROVs), seabed mining vehicles, underwater cameras and other underwater operating equipment for scientific research or commercial purposes. The LARS system consists of a swing frame device, a guide device, a winch device and a control system. The swing frame device is a large swing arm that can be retracted and adjusted and installed on the hull; the guide device and the winch device are installed on the swing frame device, and the interface between the guide device and the underwater equipment allows the equipment to be docked and separated from the A-frame; the winch device controls the lifting and lowering of the guide mechanism and the underwater equipment. Under the coordinated control of the control system, the underwater operating equipment is deployed from the ship into the sea, or recovered from the sea to the ship.

[0003] The marine environment contains natural forces such as waves, currents and wind, which can cause the swinging device and the connected underwater equipment to swing. Frequent or violent swinging can damage the underwater equipment and shorten its service life. When deploying and recovering underwater equipment, very precise operations are required to ensure that the guide device and the underwater equipment are properly docked.

[0004] Most existing swinging devices are not equipped with anti-sway devices. The swinging of the swinging device and the underwater equipment makes the docking process very difficult. The swinging requires extra time and effort to control, which reduces the efficiency of the operation. The swinging causes the underwater equipment to collide with the swinging device or other structures, causing equipment damage and resulting in higher maintenance and repair costs.

[0005] Therefore, setting up an effective underwater anti-sway swing frame device is crucial to ensure the safety, stability and operating efficiency of underwater operating equipment. Utility Model Content

[0006] In order to solve the problems existing in the background technology, the utility model provides an underwater deployment anti-sway swing frame device, which includes:

[0007] A boom, the boom comprising two bases mounted on the hull and swing arms hinged on the bases, the two swing arms being connected by a crossbeam;

[0008] A luffing cylinder, one end of which is hinged to the base and the other end is connected to the swing arm, for driving the swing arm to adjust the angle;

[0009] A fixed frame, the fixed frame is suspended on the crossbeam, and a wire rope winch and an umbilical guide wheel are installed on the fixed frame;

[0010] The anti-swing device comprises a first suspension bracket installed on the crossbeam and a second suspension bracket installed on the fixed frame. An anti-swing oil cylinder is arranged between the first suspension bracket and the second suspension bracket, and the anti-swing oil cylinder has a buffering effect on the swing of the fixed frame through the extension and retraction of the anti-swing oil cylinder.

[0011] In a preferred solution, the anti-swing cylinder is fixedly connected to the first suspension bracket, and the telescopic arm of the anti-swing cylinder is fixedly connected to the second suspension bracket.

[0012] In a preferred solution, a telescopic cylinder is installed on the fixed frame, a telescopic frame is sleeved under the fixed frame, and a telescopic arm of the telescopic cylinder is connected to the telescopic frame to drive the telescopic frame to perform a telescopic action.

[0013] In a preferred solution, a wear-resistant block is provided at the sleeve joint between the telescopic frame and the fixed frame.

[0014] In a preferred solution, a bell mouth is provided at the bottom of the telescopic frame.

[0015] In a preferred solution, a guide mechanism is connected below the telescopic frame, and the guide mechanism is connected to the wire rope winch via a wire rope.

[0016] The beneficial effects achieved by the utility model are:

[0017] First, the utility model ensures the flexibility and operating range of the swing frame device through the articulated design of the boom and the angle adjustment capability of the variable-length cylinder. The setting of the anti-swing device enables the anti-swing cylinder to absorb and buffer the swing energy more directly and effectively, reduces the swing amplitude, improves the control accuracy of the swing frame device and the smoothness of operation, enhances the stability of the operation, and plays an important role in ensuring the safety of underwater equipment.

[0018] Second, telescopic cylinders and telescopic frames are added to the fixed frame, so that the guiding mechanism and operating equipment carried by the fixed frame can adjust the telescopic length according to actual needs, making it easier to swing the swing frame device on the hull to adjust the use status, expanding the application range of the device, improving the flexibility and accuracy of equipment docking, and optimizing the operational convenience during deployment and recovery.

[0019] Third, the wear-resistant block is set at the joint of the telescopic frame and the fixed frame, which effectively reduces the wear between the two, extends the service life of the equipment, and at the same time reduces the noise and vibration that may be caused by friction, thereby improving the durability of the overall system and the continuity of operation.

[0020] Fourth, the flared design at the bottom of the telescopic frame helps to provide guidance for the docking of the guiding mechanism, improves the efficiency and accuracy of docking, and ensures smooth and safe underwater operations. BRIEF DESCRIPTION OF THE DRAWINGS

The structure and function of each part are as follows:

[0030] The arm frame 1 is composed of two bases 11 , a swing arm 12 and a cross beam 13 . The swing arm 12 is hinged on the base 11 , and the two swing arms 12 are connected by the cross beam 13 .

[0031] One end of the boom cylinder 14 is hinged to the base 11 , and the other end is connected to the swing arm 12 , so as to drive the swing arm 12 to adjust the angle, thereby changing the operating range of the swing frame device.

[0032] The fixing frame 2 is suspended on the cross beam 13, on which a wire rope winch 21 and an umbilical cord guide wheel 22 are installed. The umbilical cord on the umbilical cord guide wheel 22 is used to drive the lifting of the underwater working equipment 6. The wire rope of the wire rope winch 21 is used to drive the guiding mechanism 5 to lift.

[0033] The anti-sway device 4 includes a first suspension bracket 42 mounted on the crossbeam 13, and a second suspension bracket 43 mounted on the fixing frame 2. An anti-sway oil cylinder 41 is arranged between the two suspension brackets, and the anti-sway oil cylinder 41 acts as a buffer to the swing of the fixing frame 2 and reduce the swing amplitude through the extension and contraction of the anti-sway oil cylinder 41.

[0034] A telescopic oil cylinder 31 is installed on the fixed frame 2, and a telescopic frame 3 is sleeved below the fixed frame 2. The telescopic arm of the telescopic oil cylinder 31 is connected to the telescopic frame 3 to drive the telescopic frame 3 to perform telescopic movements. A guide mechanism 5 is connected below the telescopic frame 3, and the guide mechanism 5 is connected to the wire rope winch 21 through a wire rope. After the guide mechanism 5 is docked with the underwater operating equipment 6, the underwater operating equipment 6 can be driven to rise and fall by the wire rope.
