Description

Technical Field

[0001] The present invention relates to the field of yachts, and particularly to a dinghy boom mechanism in a yacht. Background Art

[0002] Many luxury yachts of a certain size are equipped with dinghies for personnel boarding, life-saving emergencies, etc. Some yachts adopt a dinghy parking platform at the boat section, and the dinghy is launched and lowered onto the platform through a dinghy hoisting mechanism. Since luxury yachts have a lightweight composite boat hull structure, with a compact hull space and a grand, luxurious and beautiful appearance, they generally tend to adopt a hidden dinghy hoisting mechanism. The dinghy hoisting mechanisms currently used in yachts are roughly as follows: 1) a rod-type dinghy hoisting mechanism, where the rod structure is exposed in the hull space, occupying the hull space and affecting the aesthetics of the yacht; 2) a gravity-type multi-section telescopic cantilever dinghy hoisting mechanism, which to a certain extent meets the functions of stretching and suspending and contracting and hiding when the boom mechanism is in use and idle, but the sectional telescopic cantilever cannot completely hide the boom mechanism, and the extension and contraction of the cantilever are carried out at stage-length distances, and precise displacement control cannot be achieved.

An installation groove 101 along the axial direction of the yacht is arranged on the flying bridge 100 of the luxury yacht from the rear end forward. The moving beam 1 can move back and forth along the installation groove and is telescopically arranged in the flying bridge of the yacht. When the lifeboat hoisting device is not in use, the moving beam 1 is arranged in the installation groove 101. The moving beam 1 can be made of aluminum profiles with a rectangular cross-section. Reinforcing rib plates can be arranged inside the rectangular frame. The sum of the height of the moving beam 1 and the height of the accessory components arranged on the moving beam 1 is less than the depth of the installation groove. The flying bridge refers to the second or top deck of the luxury yacht.

[0027] A lifting drive mechanism 2 is arranged at the tail end of the moving beam. The lifting drive mechanism 2 can adopt a small winch device. The lifting drive mechanism 2 is used to connect with the lifting rope 201 connected to the lifeboat 200 so as to enable the lifeboat to move back and forth (when the moving beam 1 moves) and lift. The electrical connection line of the lifting drive mechanism 2 can be routed inside the moving beam 1.

[0028] The lifeboat hoisting device is provided with a moving beam drive mechanism. The moving beam drive mechanism is provided with a bidirectional cable system driven by a motor to drive the moving beam 1 to move back and forth. A movable pulley is arranged on the cable running line of the bidirectional cable system in the installation groove 101. The moving beam 1 is provided with a connecting structure. The connecting structure is arranged in the installation groove. The movable pulley is installed on the connecting structure. The moving beam 1, the connecting structure and the movable pulley move together to achieve force reduction transmission and hidden layout.

[0029] A plurality of fixed pulleys are arranged in the bidirectional cable system. The fixed pulleys are divided into a first group and a second group. The first group of fixed pulleys 30 is arranged at the front end of the installation groove 101. The second group of fixed pulleys 40 is arranged at the front end of the installation groove 101. An inlet and outlet 102 is arranged in the middle of the rear end of the installation groove 101. The front part of the moving beam 1 enters and exits through the inlet and outlet 102. The first group of fixed pulleys 30 is installed on the front end wall of the installation groove 101. The second group of fixed pulleys 40 is installed on the end wall at the rear end of the installation groove 102 beside the inlet and outlet 102.

[0030] The movable pulleys are also divided into a first group and a second group. The first group of movable pulleys is combined with the first group of fixed pulleys, and the second group of movable pulleys is combined with the second group of fixed pulleys. There are multiple movable pulleys in both the first group of movable pulleys and the second group of movable pulleys. The movable pulleys in both the first group of movable pulleys and the second group of movable pulleys respectively include horizontally arranged movable pulleys and vertically arranged movable pulleys.

[0031] In this embodiment, a two - group 3 + 2 configuration is adopted, that is, each pulley mechanism adopts 3 fixed pulleys and 2 movable pulleys. Among the two fixed pulleys, one is horizontally arranged and the other is vertically arranged, which is convenient for the hidden layout of the sliding mechanism and the threading of the pulling rope. At the same time, it can achieve sufficient force reduction effect, appropriate telescopic running speed and precise movement. Among them, the first - group fixed pulleys in the first - group sliding mechanism are numbered 31, 32, 33 respectively, the horizontally arranged movable pulley in the first - group movable pulleys is numbered 34, the vertically arranged movable pulley in the first - group movable pulleys is numbered 35, the second - group fixed pulleys in the second - group sliding mechanism are numbered 41, 42, 43 respectively, the horizontally arranged movable pulley in the second - group movable pulleys is numbered 44, and the vertically arranged movable pulley in the second - group movable pulleys is numbered 45. The fixed pulleys are all horizontally arranged.

[0032] As Figure 2 , 3 , as shown in Figure 4, the connection structure is preferably arranged at the tail of the moving beam 1, and the connection structure is set as a track - sliding trolley 5. The movable pulley is arranged on one side of the track - sliding trolley; the track - sliding trolley 5 includes a structure on the first side and a structure on the second side of the moving beam 1. The first side and the second side are respectively one of the left side and the right side and the other of them; among them, the structure on the first side is provided with the movable pulley.

The first cable and the second cable respectively enter the threading lines in the installation groove 101 through the first guide pulley 61 and the second guide pulley 62, and are respectively first connected to the first side fixed pulley 31 and the second side fixed pulley 41, and then pass through the movable pulley and the fixed pulley and are connected to the cable end connection structure 50 installed in the structure on the first side. The cable end connection structure 50 can be a loop for tying a rope. In the threading line, for the first group of movable pulleys, the horizontally arranged movable pulley 34 is closer to the first guide pulley 61 than the vertically arranged movable pulley 35. For the second group of movable pulleys, the horizontally arranged movable pulley 44 is closer to the second guide pulley 62 than the vertically arranged movable pulley 45.

[0036] The lifeboat hoisting device is provided with a guide rail system for the front and rear movement of the moving beam 1; preferably, the guide rail system is simultaneously provided with an upper guide rail system and a lower guide rail system. Both the upper guide rail system and the lower guide rail system respectively have guide rails fixed on the flying bridge and slide rails slidably matched with the guide rails. The slide rail 71 in the upper guide rail system is arranged on the top of the moving beam 1, and the lower guide rail system is respectively arranged on both sides of the upper guide rail system, so as to form a trapezoidal or triangular support. Moreover, through the positioning of the upper guide rail system, when the moving beam extends to work, especially when it extends to the end, the problem of the moving beam 1 sagging can be avoided.
