[0002] With the increasing development of the ocean, submersible mother ships need to be able to carry out the deployment and recovery operations of various submersibles, including manned / unmanned submersibles, submarine rescue boats, diving bells, unmanned ships, etc. Since the functions, interfaces and operation requirements of these instruments and equipment are different, dedicated deployment equipment is usually used for deployment and recovery operations. However, due to the limited deck space of the submersible support mother ship, crew operation and maintenance support, etc., it is very difficult and impossible to equip multiple deployment and recovery systems. At present, major foreign submersible deployment and recovery system manufacturers have not yet been involved in the research and application of multi-object deployment and recovery systems on a large scale. Mainstream manufacturers are more focused on the integration and development of single submersible deployment systems, and the research on multi-functional guide joints is still in the initial stage.

[0003] At present, in the lifting system used in construction, as described in the disclosed patents CN109334874, CN109229283, CN109229284, etc., a special gantry or other lifting device is used, and then a winch in the cabin or a winch on the deck is used for lifting and lowering operations. This type of equipment occupies a large deck space and requires a complete set of hydraulic and electronic control equipment. Summary of the invention

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 As shown, a common swing frame of a guide device suitable for various deep-sea equipment of the present invention is mainly composed of a swing frame 1, a guide frame 2, a maintenance platform 3, a main lifting winch 4, an auxiliary lifting winch 5, and a hydraulic cylinder 6.

[0024] The swing frame 1 is the main load-bearing structure during the operation, and is mainly composed of the swing frame mechanism body 1.1, the telescopic frame 1.2, and the guide pulley 1.3. The guide frame 2 is composed of the guide frame mechanism body 2.1 and the universal automatic locking device 2.2. The main structure of the maintenance platform 3 is made of welded steel, and is bolted to the swing frame mechanism body 1.1. A grid plate is laid on the top to support the repair and maintenance of the equipment; the main lifting winch 4 is used for the lifting and lowering of large submersibles. The drum winds the cable and provides tension for the cable. The main lifting winch 4 is composed of a bracket 4.1, a cylinder 4.2, a reducer 4.3, a hydraulic motor 4.4, etc., and adopts two drive systems, each of which includes two hydraulic motors 4.4 and a reducer 4.3. The auxiliary lifting winch 5 has a similar structure to the main lifting winch, and is composed of a bracket 5.1, a cylinder 5.2, a reducer 5.3, a hydraulic motor 5.4, etc. The hydraulic cylinder is composed of an anti-swing cylinder 1 6.1, an anti-swing cylinder 2 6.2, and a telescopic column cylinder 6.3.

[0025] The swing frame structure body 1.1 is welded from a box beam and is the main load-bearing component during the lifting operation. The upper part is hinged with the lifting device hanger to release the degree of freedom during the lifting operation, thereby reducing the overall structural rigidity of the lifting device. An opening is provided at the lower part so that the telescopic column 1.2 can complete the telescopic action along the box structure;

[0026] Since the public swing frame needs to adapt to different submersibles, the submersibles are of different sizes, and the transfer heights are inconsistent when the submersibles are transferred from the hanging device to the deck surface, in order to reduce the transfer stroke as much as possible, a telescopic frame 1.2 is arranged on the public swing frame. The telescopic frame 1.2 completes the telescopic action in the opening of the swing frame structure body 1.1 through the telescopic column cylinder 6.3, thereby reducing the free release stroke of the submersible;

[0027] The main structure of the telescopic frame 1.2 is welded from a box beam, with telescopic columns on both sides. The two sides of the telescopic columns are bolted to nylon sliders to achieve smooth telescopic movement. The bottom of the telescopic frame 1.2 is provided with an interface hinged with the guide frame 2;

[0028] The guide pulley 1.3 is welded to the swing frame structure body 1.1 and is used for guiding the umbilical cable of the submersible and supporting the load;

[0029] The guide frame body 2.1 is hinged with the telescopic frame 1.2, releasing the degree of freedom of swinging along the twisted shaft, reducing the overall rigidity of the guide device after being connected to the submersible. The side is hinged with the telescopic frame 1.2 through two anti-swing oil cylinders 6.2, which can adjust the swing posture of the submersible and realize the anti-swing function;

[0030] The common swing frame can be rigidly connected to various submersible docking devices through the universal locking device 2.2; the universal locking device is composed of a docking mechanism 2.2.1, a guide cylinder 2.2.2, a locking device cylinder 2.2.3, and a spring 2.2.4. The guide cylinder 2.2.2 plays a positioning role. Through the combined action of the locking device cylinder 2.2. and the spring 2.2.4, the load-bearing head on the auxiliary suspension cable can be automatically locked and can be actively opened.

[0031] The main lifting winch 4 and the auxiliary lifting winch 5 are both composed of a bracket, a cylinder, a reducer, a hydraulic motor, etc. The main lifting winch is mainly used for lifting and lowering various manned submersibles and is arranged on a common swing frame; the auxiliary lifting winch is mainly used for lifting and lowering burying machines, mining vehicles and various submersible docking devices.

[0032] The common swing frame is integrated with the swing frame 1, the guide frame 2, the maintenance platform 3, the main lifting winch 4, the auxiliary lifting winch 5, the hydraulic cylinder 6, etc., so as to achieve the adaptation of different submersibles.

[0033] The swing frame 1 is welded into a rectangular frame by box girders. A guide pulley 1.3 is arranged on the upper part of the frame for guiding the umbilical cable and supporting the weight of the umbilical cable itself. The installation base plate for the main lifting winch and the auxiliary lifting winch is arranged in the middle of the frame. A maintenance platform is arranged under the three lifting winches for daily maintenance and repair of the equipment. The maintenance platform structure body is connected to the swing frame mechanism body 1.1 by bolts and is welded into a frame by box girders. A grid plate is laid on the top of the maintenance platform structure, and handrails and guardrails are arranged around it. The swing frame structure body 1.1 has open cavities on both sides, which are mainly used for the telescopic guidance of the telescopic frame 1.2. The telescopic frame 1.2 is an inverted П-shaped structure. The upper part of the telescopic frame 1.2 is two telescopic box girders, and the lower part is a connecting crossbeam, which is mainly used to connect the guide frame.

[0034] The upper lifting lug of the guide frame structure body 2.1 is connected to the telescopic frame in an articulated manner, and the left and right sides are the hinge points of the transverse oil cylinder and cooperate with the hydraulic system to achieve the anti-swing function. A universal automatic locking device is arranged in the structure body, which is used to automatically lock the bearing head on the auxiliary lifting cable and can be actively opened.

[0035] The main hoist winch is used to hoist and lower manned submersibles. It is a device that retracts and releases cables and provides tension for the cables. The reducer is equipped with a normally closed brake, which is hydraulically controlled. When the cables are retracted and released, hydraulic oil enters the brake to open the brake, and the hydraulic motor drives the cylinder to rotate through the reducer. The winch stops under any conditions, and the normally closed brake ensures that the cylinder is braked and the submersible is kept in the braking position. When recovering the submersible, in order to reduce the impact of waves on the cables and submersibles, the winch provides a cable constant tension control function, so that the cables always remain in a small tension load tension state to ensure safety.

[0036] The auxiliary lifting winch is used for lifting and lowering burial machines, mining vehicles and various submersible docking devices, and has a similar structure to the main lifting winch.

[0037] Hydraulic cylinders, two sets of anti-sway cylinders 6.1 are provided between the swing frame 1 and the hanger crossbeam, which are used to control the posture and damp the swing along the cylinder hinge swing direction. Two sets of anti-sway cylinders 6.2 are provided between the telescopic column and the guide joint, which are used to control the posture and damp the swing along the cylinder hinge swing direction. The telescopic column is driven by the telescopic column cylinder 6.3 to move up and down linearly, and can stop at any position during the lifting process, and has the ability to maintain position.
