Description

Technical Field

[0001] The utility model relates to ocean engineering equipment, and more specifically, to a rope arranging device for a large waterfall-type triangular mooring winch. Background Art

[0002] An anchor handling tug supply vessel (AHTS) is a multi-functional ocean engineering ship. In recent years, its working area has gradually developed from inshore waters to open ocean waters, and the requirements for the mooring winch in terms of towing force, rope capacity, function, etc. are also getting higher and higher. When designed to work in the open ocean, the winding and arranging situation of the steel wire rope on the drum determines the operation efficiency. Generally, the mooring winch is equipped with 2 drums, which are arranged in a waterfall pattern. The drum below is used as the anchor handling drum, and the space around the drum has little influence on the arrangement of the rope arranging device. The structure is similar to that of Patent 1, "A Separable Rope Guiding Frame Device" (Patent Application No. 202221318718.1). This structure can be arranged inside the whole machine, and the idler can be separated, but it is only applicable to a single drum with the same steel wire rope specification. Or as shown in Patent 2, "An Openable and Closeable Rope Arranging Device for a Mooring Winch and the Mooring Winch" (Patent Application No. 202320344126.5), its structure can meet the requirements of idler separation and also meet the requirements of variable steel wire rope specifications, but it is only applicable to a single drum, only arranged outside the whole machine, and the oil cylinder extends outwards.

[0003] When there are较多 anchor handling operations on the AHTS, its mooring winch is equipped with 3 drums, which are arranged in a waterfall-type "triangle" pattern. Among them, 2 drums are used for anchor handling operations, and generally they are coaxially arranged. No matter which of the above structures is adopted, it cannot meet the requirements that under the minimum overall machine external dimension, these 2 drums can arrange steel wire ropes with different diameters and can pass through shackle fittings. Summary of the Utility Model

[0004] Aiming at the defects existing in the prior art, the purpose of the utility model is to provide a rope arranging device for a large waterfall-type triangular mooring winch, which can arrange steel wire ropes with different diameters, thereby meeting different anchor handling function operations, and can pass through large-size shackles and thimbles and other fittings to improve the efficiency of anchor handling work.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rope arranging device for a large waterfall-type triangular mooring winch includes a fixed slide rail, a fixed frame, a hydraulic cylinder, and a slide frame assembly;

[0007] The fixed slide rail and the fixed frame are both arranged on the frame body of the mooring winch;

[0021] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Combination Figures 1 to 4As shown, the utility model provides a waterfall-type herringbone-shaped large-scale towing rope arranger, which includes a fixed slide rail 1, a fixed frame 2, a hydraulic cylinder 3 and a slide frame assembly 4.

[0023] The fixed slide rail 1 and the fixed frame 2 are both arranged on the frame body of the towing winch (see Figure 1 position in the dotted box).

[0024] A pair of hydraulic cylinders 3 are provided, the telescopic ends of which are arranged opposite to each other and connected to the corresponding slide assemblies 4 , and the fixed ends are hinged to the fixed frame 6 .

[0025] A pair of slide assemblies 4 are provided, both of which are mounted on the fixed slide rail 1 and move on the fixed slide rail 1 and are respectively connected to the telescopic ends of the corresponding hydraulic cylinders 3.

[0026] The corresponding slide assembly 4 is driven by the hydraulic cylinder 3 to move along the fixed slide rail 1, so that a rope arrangement device separation area can be formed between the two sets of slide assemblies 4.

[0027] The carriage assembly 4 includes a carriage body 41 , a first sliding block 42 and a second sliding block 43 .

[0028] The first sliding block 42 and the second sliding block 43 are respectively connected to two ends of the sliding frame body 41 .

[0029] The first slider 42 and the second slider 43 are both provided with a roller assembly 5 .

[0030] A connecting plate 44 for connecting to the telescopic end of the hydraulic cylinder 3 is provided on the inner side end of the second sliding block 43 .

[0031] A limit adjustment block 6 is provided on the first sliding block 42 .

[0032] The hydraulic cylinder 3 is controlled by the control system to drive the slide assembly 4 to move on the fixed slide rail 1, so that a certain gap is maintained between the roller assembly 5 on the first slider 42 in one group of slide assemblies 4 and the roller assembly 5 on the second slider 43 in another group of slide assemblies 4, thereby allowing the towing winch to pass through a wire rope of specified specifications (i.e., the rope arrangement separation area).
