Description

Technical Field

[0001] The invention relates to an ARV deployment and recovery system in a ship system and equipment, in particular to an anti-swing device for ARV deployment and recovery. Background Art

[0002] With the continuous development of marine equipment technology, the functions and performance of anti-sway devices, as an important part of the ARV deployment and recovery system in ship systems and equipment, are increasingly valued. Traditional anti-sway devices are widely used in a variety of marine operating environments. However, they generally have the defect of being unable to accurately adjust the lifting height. This defect not only limits the flexibility of the anti-sway device under different loads and operating conditions, but may also affect the efficiency and safety of the overall deployment and recovery process. In order to better meet the needs of complex marine operations, many research institutions and enterprises at home and abroad are actively developing new anti-sway devices to improve their performance and adaptability to ensure the efficient and safe operation of the ARV system.

[0003] At present, as described in the disclosed patents CN112794207, CN112758256, etc., a swing stop frame is used to adjust the lifting height. The stroke of this type of vertical telescopic structure is limited by the cylinder, and due to the increase in the length of the cylinder, the overall height of the swing stop is higher, and a larger avoidance space is required during deployment and recovery, which limits its scope of application. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes an anti-sway device for deploying and recovering ARV. The bipolar extension of the anti-sway device can adjust the lifting height to complete the deployment and recovery operations between the inboard and outboard of the ARV, ensuring that the ARV works smoothly and does not collide with the A-frame and the deck; the ARV can be controlled to rotate 360° by operating the rotary control valve, which is more convenient for the deployment and recovery operations of the ARV.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: an anti-sway device for ARV deployment and recovery, including a swing frame, a telescopic column, a cylinder, a guide pulley, a flip frame, a rotary drive device, a guide joint and a hydraulic system. The swing frame is equipped with a guide pulley, and the swing frame is connected to the telescopic column through a telescopic cylinder. The telescopic column is driven by the telescopic cylinder to move up and down in a straight line, and can stop at any position during the lifting process to complete the adjustment of the lifting height.

[0006] Furthermore, the swing frame is a frame structure, four lifting ears are arranged on the top of the swing frame, and are connected to the lifting point at the bottom of the A-shaped frame beam through a pin shaft, four anti-pitch cylinders are arranged on the swing frame, and the bottom of the swing frame is a rectangular track cavity.

[0007] Furthermore, the middle of the guide pulley is installed on the support plate of the swing frame through a pin shaft; the guide pulley is provided with a standard groove shape, which can smoothly pass the armored cable.

[0008] Furthermore, a sliding block is provided between the upper part of the telescopic column and the swing frame, and the lower part is connected to the flip frame through a pin; the upper part of the flip frame is connected to the telescopic column through a pin, and anti-pitch cylinders are installed on the left and right.

[0009] Furthermore, the telescopic column is an H-shaped box beam structure, and two telescopic beams on the left and right are connected together by a cross beam.

[0010] Furthermore, the lower part of the turning frame is connected to the turning support of the turning drive device, and the turning drive mechanism of the turning drive device is installed on the flange hole of the turning frame.

[0011] Furthermore, the guide joint is connected to the lower part of the slewing drive mechanism by bolt connection, and both ends of the anti-pitch oil cylinders on the left and right sides are respectively hinged on the guide joint and the telescopic column, and cooperate with the hydraulic system to achieve lateral anti-sway.

[0012] Furthermore, a locking mechanism is installed on the bell mouth of the guide joint, and the locking mechanism is driven by a locking cylinder. When the guide joint completes the interlocking of the submersible, the locking cylinder provides a pressing force to ensure reliable locking.

[0013] Furthermore, the slewing drive device is composed of a slewing drive mechanism and a slewing support. The slewing drive mechanism is composed of a cycloidal motor, a reducer and a pinion. The cycloidal motor can rotate in both directions and has a self-locking function; the input end of the reducer is connected to the cycloidal motor through a spline, and the output end is connected to the pinion; the outer ring of the slewing support is connected to the guide joint, and the inner ring is connected to the telescopic column; the slewing drive device can achieve 360° rotation.

[0014] Furthermore, the anti-sway device adopts a four-point anti-sway form, which can effectively play a role in buffering and shock absorption and meet the docking requirements.

[0015] The technical solution of the present invention has the following beneficial effects:

[0016] 1) The telescopic column can be extended and retracted through the action of the telescopic cylinder in the anti-swing device for ARV deployment and recovery, thereby completing the adjustment of the lifting height.

[0017] 2) A locking device is set on the guide joint so that the oil cylinder has a locking function, and a limit device is provided to clearly indicate the locking state, thereby ensuring the reliability of the submersible attachment.

[0018] 3) The anti-swing device adopts a four-point anti-swing form, and uses a damper to buffer and reduce shock to meet the anti-swing point docking requirements. BRIEF DESCRIPTION OF THE DRAWINGS
