[0023] Example:

[0024] This embodiment discloses an electric ship shape lifting system.

[0025] like Figure 1 As shown, the electric ship shape lifting system is used for the hull, the upper end of the hull is provided with a deck 1, the upper end of the deck 1 is provided with a shaping structure 2, and the shaping structure 2 is provided with a mast 4.

[0026] The electric ship shape lifting system includes an electric hoist 3, a first fixed pulley 11, a mounting plate 5, a shape 6, and a traction rope 7. The electric hoist 3 is mounted at the rear end of the shaping structure 2. The first fixed pulley 11 is mounted on the deck 1. The mounting plate 5 is connected to the upper end of the mast 4, with the second and third fixed pulleys 51, 52 located at its lower end. The traction rope 7 is connected to the output of the electric hoist 3 at its first end, passes through the first, second, and third fixed pulleys 11, 51, 52, and finally to the upper end of the shape 6 at its second end.

[0027] When viewing the electric ship shape lifting system from above, the first and second fixed pulleys 11 and 51 are located at the front of the shape 6 and at the rear of the electric hoist 3 and the shaping structure 2. Preferably, the traction rope 7 is maintained vertically between the first and second fixed pulleys 11 and 51 to prevent collision and friction with other structures. Deep-groove fixed pulleys are used.

[0028] Furthermore, the mounting plate 5 includes a first limit switch 53, which is arranged at the lower end of the mounting plate 5 and is located at the rear end of the third fixed pulley 52. ​​The traction rope 7 includes a guide plate 71, which is arranged on the traction rope 7 and is located between the size 6 and the third fixed pulley 52. ​​Among them, when the size 6 rises to the upper limit position, the guide plate 71 triggers the first limit switch 53. Exemplarily, the guide plate 71 is an inverted cone, and the guide plate 71 is clamped on the traction rope 7 by a shackle. The guide plate 71 itself has a certain weight, and during the descent process, it descends with the traction rope 7 by relying on its own gravity. Specifically, the first limit switch 53 is a photoelectric proximity switch, which avoids the risk of failure of the mechanical contacts of ordinary travel switches due to corrosion by marine salt spray.

[0029] Furthermore, the mounting plate 5 includes a second limit switch 54, which is located at the lower end of the mounting plate 5 and in front of the second fixed pulley 51. The traction rope 7 includes a limit block 72, which is installed on the traction rope 7 and located between the first fixed pulley 11 and the second fixed pulley 51. When the model 6 descends to the lower limit position, the limit block 72 triggers the second limit switch 54. Specifically, the second limit switch 54 is a photoelectric proximity switch, which avoids the risk of failure of the mechanical contacts of a conventional limit switch due to corrosion from marine salt spray.

[0030] Furthermore, the size 6 includes an expansion ring 61, which is provided at the lower end of the size 6. There are several size 6, and the upper end of the next size 6 is connected to the expansion ring 61 of the previous size 6 through a wire rope.

[0031] Furthermore, the electric ship shape lifting system includes a guide wire 8, which is vertically arranged with its first end connected to the deck 1 and its second end connected to the mounting plate 5, positioned between the shape 6 and the towing rope 7. The shape 6 includes an anti-drift rope 62, the front end of which is sleeved over the guide wire 8 and the rear end is sleeved over the expansion ring 61. The guide wire 8 also passes through a guide plate 71, preventing it from drifting in the wind and leaving the sensing area of ​​the first limit switch 53.

[0032] Furthermore, the ship's electric number lifting system includes an electric control box 9, which is arranged on the hull and is electrically connected to the electric hoist 3, the first limit switch 53 and the second limit switch 54. The electric control box 9 receives remote control signals from an external operator and controls the electric hoist 3 to start, and the electric control box 9 receives detection signals from the first limit switch 53 and the second limit switch 54 and controls the electric hoist 3 to stop. In this application, electrical connection refers to the form of connection between different components in a circuit through physical lines such as PCB copper foil or wires that can transmit electrical signals. Specifically, the cables of the first limit switch 53 and the second limit switch 54 pass through the mounting plate 5, the mast 4 and the shaping structure 2 to connect to the electric control box 9, and the cables of the electric hoist 3 pass through the shaping structure 2 to connect to the electric control box 9, which facilitates unified cable organization and maintenance. The electric control box 9 can use a commercially available PLC control box with an integrated signal receiving module, and the control program belongs to the existing technology.

[0033] In this embodiment, the hull mast 4 is used as the main structure, the electric hoist 3 is used as the power, the first fixed pulley 11 on the deck 1 and the second fixed pulley 51 and the third fixed pulley 52 on the mounting plate 5 guide the traction rope 7, and the electric hoist 3 reels in and unreels the traction rope 7 to achieve automatic lifting and lowering of the number type 6. The structure is simple, the operation is convenient, and the operator is protected from injury.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
