[0002] Ship-borne hangers are generally used to lift rescue boats or cargoes. The hanger for lifting rescue boats is called a boat hanger, and the hanger for lifting cargoes is called a cargo hanger. Boat hangers are generally essential first aid equipment for ships, and the installation of cargo hangers depends on whether the ship needs to load and unload cargo. Most ships have both boat hangers and cargo hangers, and are arranged on the deck for easy operation. However, the two hangers occupy a large space on the plywood, especially the cargo hanger has a large lifting range, so a large space needs to be reserved on the deck, resulting in a large waste of space. Summary of the invention

[0006] Furthermore, the double-drum rope guide also includes a connected drum seat and a drum support rod, the drum seat is installed on the boom, and the boat lifting rope guide drum and the object lifting rope guide drum are respectively arranged at both ends of the drum support rod, so that the boat lifting rope and the object lifting rope are pulled through the drum support rod.
[0007] Furthermore, the double-barrel rope guide on the boom is arranged close to the hydraulic hoisting winch.
[0008] Furthermore, the boat-lifting rope is connected to a detachable buckle group after passing through the pulley guide ropes at the rear end and side of the boom, and the buckle group is used to lift the rescue boat. The object-lifting rope is connected to a detachable hook group after passing through the pulley guide ropes at the front end of the boom, and the hook group is used to hook the cargo.
[0009] Furthermore, the boom is hingedly connected to the tower on the hydraulic slewing mechanism, and a luffing cylinder is connected between the boom and the tower, and two ends of the luffing cylinder are hingedly connected to the boom and the tower respectively.
[0010] Furthermore, the hydraulic slewing mechanism is installed on a ship-borne base of the hydraulic slewing hanger body.
[0011] Beneficial effects: The utility model integrates a hydraulic boat lifting winch and a hydraulic cargo lifting winch on the hydraulic slewing hanger, so as to lift rescue boats and cargoes according to the needs of the ship, thereby meeting the dual functional requirements of the ship-borne hanger for lifting boats and cargoes. Only one hydraulic slewing hanger is required to take into account both the boat lifting and cargo lifting operations, which greatly saves the space occupied by the deck and is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model;
[0013] Attached Figure 2 It is a schematic diagram of the structure of a double-tube rope guide. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] As attached Figure 1 As shown, a hydraulic slewing hanger for both boat and cargo lifting comprises a hydraulic double winch group arranged on the hydraulic slewing hanger body, the hydraulic double winch group being composed of a hydraulic boat lifting winch 8 and a hydraulic cargo lifting winch 9 respectively arranged on the hydraulic slewing mechanism 2 of the hydraulic slewing hanger body. The utility model integrates the hydraulic boat lifting winch 8 and the hydraulic cargo lifting winch 9 on the hydraulic slewing hanger, thereby lifting a rescue boat 10 and cargo according to the needs of the ship, thereby meeting the dual functional requirements of the ship-borne hanger for boat lifting and cargo lifting. Only one hydraulic slewing hanger is required to take into account both boat lifting and cargo lifting operations, thereby greatly saving deck space. It should be noted that since the hydraulic slewing hanger integrates the routing of the hydraulic boat lifting winch 8 and the hydraulic object lifting winch 9, that is, the double routing structure composed of the boat lifting rope 80 and the object lifting rope 90, it is necessary to guide the double routing structure in the routing direction and constrain the non-routing pay-out. Therefore, in the utility model, a double-cylinder rope guide 11 is provided on the boom 4, and the boat lifting rope 80 of the hydraulic boat lifting winch 8 and the object lifting rope 90 of the hydraulic object lifting winch 9 are guided by the double-cylinder rope guide 11, thereby respectively realizing the guidance of the boat lifting rope 80 and the object lifting rope 90 in the routing direction and the constraint in the non-routing direction, thereby ensuring the smooth progress of the boat lifting operation and the object lifting operation.
[0016] More specifically, as Figure 2The double-drum rope guide 11 includes a boat-lifting rope guide drum 1.3 and a lifting rope guide drum 1.4 fixedly arranged relative to the boom 4. The boat-lifting rope 80 shuttles through the boat-lifting rope guide drum 1.3, and the lifting rope 90 shuttles through the lifting rope guide drum 1.4. The double-drum rope guide 11 also includes a connected drum seat 1.1 and a drum support rod 1.2. The drum seat 1.1 is installed on the boom 4. The boat-lifting rope guide drum 1.3 and the lifting rope guide drum 1.4 are respectively arranged at both ends of the drum support rod 1.2, so that the boat-lifting rope 80 and the lifting rope 90 are pulled through the drum support rod 1.2. Through this pulling, the boat-lifting rope 80 and the lifting rope 90 have a mutual restraint effect to prevent the ropes from falling off the wheel or running off.
[0017] As attached Figure 1 As shown, the double-barrel rope guide 11 on the boom 4 is arranged close to the hydraulic hoisting winch 9, so that the guidance is carried out at the starting position of the hydraulic hoisting winch 9, while the hydraulic boat hoisting winch 8 far away from the hydraulic hoisting winch 9 is guided in the approximate middle area of the routing.
[0018] As attached Figure 1 As shown, the boat-lifting rope 80 is connected to a detachable hook group 7 after passing through the pulley guide rope at the rear end and side of the boom 4, and the hook group 7 is used to lift the rescue boat 10. The object-lifting rope 90 is connected to a detachable hook group 6 after passing through the pulley guide rope at the front end of the boom 4, and the hook group 6 is used to hook the cargo. The hydraulic slewing mechanism 2 is installed on the ship-borne base 1 of the hydraulic slewing hanger body. The boom 4 is hingedly connected to the tower 3 on the hydraulic slewing mechanism 2, and a variable-length cylinder 5 is connected between the boom 4 and the tower 3, and the two ends of the variable-length cylinder 5 are respectively hinged to the boom 4 and the tower 3. By extending and retracting the variable-length cylinder 5, the pitch angle of the boom 4 can be changed, and the flexibility is improved, thereby changing the operating radius of the hydraulic slewing hanger to cover a larger operating range.
[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
