Description

Technical Field

[0001] This utility model relates to the field of ship fittings technology, and more specifically, it relates to a mooring winch guide rope frame device. Background Technology

[0002] In ship operations, mooring winches play a crucial role in drifting, support, and positioning during loading and unloading. They also compensate for deviations caused by vibration with constant tension, making them key equipment for ensuring the safe berthing of ships. However, cables are typically extremely long, and during winding and unwinding, multiple layers of abnormal entanglement are highly likely to occur on the reel, leading to knots and difficulties in winding and unwinding. Therefore, a cable guide frame is an indispensable accessory for mooring winches.

[0003] In existing technologies, cable guide frames typically use a screw to drive a guide block to reciprocate, allowing the cable to pass through the guide block. This causes the cable to reciprocate along the axis of the reel during winding, arranging the cable layer by layer to prevent tangling. However, marine cables usually have high tension, meaning the pressure exerted by the cable on the screw through the guide block is significant. Over time, this can easily wear down the threads and cause failure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mooring winch guide rope frame device with a longer service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mooring winch guide rope frame device includes a reel for winding a rope. An upper cable winding assembly and a lower cable winding assembly are respectively provided at the upper and lower ends of the reel. The upper pressure plate of the upper cable winding assembly can press against the rope on the reel, and the upper pressure plate guides the winding spacing of the rope. The lower cable winding assembly has the same structure as the upper cable winding assembly but is arranged facing each other. When the rope is wound on the reel in two different directions, the upper and lower cable winding assemblies act respectively. A traction assembly is provided on the side of the reel facing the working surface, and the traction assembly limits the height of the rope facing the reel side.

[0007] The present invention is further configured such that: the upper cable assembly includes an upper bracket, the upper bracket is provided with upper hydraulic rods and a plurality of upper clamping parts at intervals, the other end of the upper hydraulic rods and all the upper clamping parts are connected to an upper pressure plate, and the upper pressure plate can press against the rope on the reel.

[0008] The present invention is further configured such that: the upper pressure plate is arc-shaped on the side facing the roll shaft, and a plurality of pressure grooves are provided on the arc-shaped surface of the upper pressure plate. The pressure grooves are spiral-shaped, and the plurality of pressure grooves are arranged sequentially along the axial direction of the roll shaft. The pressure grooves can be pressed together with the rope, and the two ends of the pressure grooves are arc-shaped openings.

[0009] The present invention is further configured such that: the lower cable assembly includes a lower bracket, the lower bracket is provided with a lower hydraulic rod and a plurality of lower clamping members at intervals, the other end of the lower hydraulic rod and all the lower clamping members are connected to a lower pressure plate, the lower pressure plate is provided with a plurality of second pressure grooves, the second pressure grooves are spiral-shaped, the second pressure grooves can be pressed with the cable, and the spiral direction of the second pressure grooves is opposite to the spiral direction of the first pressure groove.

[0010] The present invention is further configured such that: the upper clamping member includes a connecting rod, the connecting rod is fixed on the upper bracket, a guide cylinder is slidably sleeved on the connecting rod, the guide cylinder is fixed on the upper pressure plate, a spring is installed axially inside the guide cylinder, and the other end of the spring is fixed on the connecting rod.

[0011] The present invention is further configured such that: the traction assembly includes a mounting base, a base frame is rotatably mounted on the mounting base, and two longitudinal guide wheels and two transverse guide wheels are rotatably mounted on the base frame. The transverse guide wheels are located near the reel. The axes of the two longitudinal guide wheels are aligned with the axis of the reel. The two longitudinal guide wheels are arranged longitudinally, and the axes of the two transverse guide wheels are arranged vertically. The two transverse guide wheels are arranged sequentially along the axis of the reel. Bracket-shaped gaps are formed between the two longitudinal guide wheels and between the two transverse guide wheels. The centers of the two bracket-shaped gaps are on the same straight line, and the cable passes through the two bracket-shaped gaps sequentially.

[0012] The present invention is further configured such that: a rotary groove is provided on the mounting base along the vertical direction; a rotating shaft is provided at the bottom of the base frame; the rotating shaft is rotatably connected to the rotary groove; a limiting groove is provided on the rotary groove; the limiting groove is an arc-shaped groove; a limiting block is correspondingly provided on the rotating shaft; the limiting block can slide in the limiting groove; and the arc center angle of the limiting groove is equal to the angle formed from the center of the rotating shaft to both ends of the scroll.

[0013] The advantages of this utility model are:

[0014] 1. An upper and lower cable laying assembly is provided, which have the same structure but face opposite directions. When the cable laying assembly is in operation, it is pressed against the rope on the reel by the clamping device. The spiral-shaped pressure groove on the inner side of the pressure plate is pressed against the loop of the rope being wound, so that the rope is arranged and wound on the reel in the corresponding spiral shape. After the rope is arranged axially on the reel for one layer, another cable laying assembly is used to make the rope arranged in the opposite direction to the upper layer in the corresponding spiral shape. This achieves the arrangement of the rope loop by loop and layer by layer on the reel. When the pressure plate presses the rope onto the reel, the rope will naturally be arranged loop by loop. The pressure groove only enhances the arrangement effect. That is, the reaction force of the rope on the pressure groove is small, so that the pressure plate is not easily damaged while realizing the cable laying function.

[0015] 2. The traction component is a rotatable structure. Through the setting of the rotary groove and the rotating shaft, the rope can drive the traction component to rotate during the winding process, thereby reducing the angle formed between the traction component and the reel, reducing the mutual compression force between adjacent turns of the rope in the same layer, that is, reducing the friction force on the pressure groove and reducing the occurrence of wear.

The two longitudinal guide wheels 43 are arranged longitudinally, and the axes of the two transverse guide wheels 44 are arranged vertically. The two transverse guide wheels 44 are arranged sequentially along the axis of the reel 1. Bracket-shaped gaps are formed between the two longitudinal guide wheels 43 and between the two transverse guide wheels 44. The centers of the two bracket-shaped gaps are on the same straight line, and the cable passes through the two bracket-shaped gaps sequentially.

[0032] The mounting base 41 has a vertically oriented rotary groove 411, and the bottom of the base frame 42 has a rotating shaft 421.
