Description

Technical Field

[0001] This utility model relates to a tension adjustment device for ship towing ropes. Background Technology

[0002] Ship towing operations have wide applications in maritime transport, rescue, fisheries, and engineering construction. During towing, the tension adjustment of the towing rope is crucial; it must ensure the rope provides sufficient traction while preventing excessive tension that could lead to rope breakage or equipment damage. Currently, towing rope tension adjustment mainly relies on electric or hydraulic drive devices. While these devices offer a high degree of automation, their complexity and energy dependence limit their use in certain remote sea areas or specific operating conditions. Furthermore, traditional equipment is complex in structure, expensive, and requires significant maintenance and operation, making it difficult to meet the demands for simple, efficient, and low-maintenance operations.

[0003] Based on this, a purely mechanical, easy-to-operate, and efficient ship towing rope tension adjustment device was designed. It can effectively adjust the tension of the towing rope through manual operation without the need for power supply, and has important practical value. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tension adjustment device for ship towing ropes.

[0005] A ship towing rope tension adjustment device includes a rope winch connected to the ship, on which a towing rope is evenly wound. One end of the towing rope is connected to the central rotating shaft of the rope winch, and the other end is connected to an anchor point. A driven sprocket is provided on the side of the central rotating shaft. The driven sprocket is connected to a drive sprocket via a chain. The drive sprocket is mounted on a sprocket bracket. A crank is provided on each side of the drive sprocket. One end of each crank is connected to the center of the drive sprocket, and the other ends of the two cranks face opposite directions and are aligned on the same straight line. One end is connected to a foot pedal. A seat cushion is provided above the drive sprocket. The seat cushion is connected to the lifting bracket. A handrail frame is provided in front of the seat cushion. The handrail frame includes a left handrail, a right handrail and a mounting frame. The left handrail, right handrail and mounting frame are connected by a detachable structure. The left handrail includes a connecting sleeve, a connecting handle and a handle. The right handrail includes a connecting rod, a connecting handle and a handle. The connecting rod is a hexagonal prism. The connecting rod is inserted into the mounting frame and then connected to the connecting sleeve. A sleeve is provided in the center of the driven sprocket. The right handrail can be inserted into the sleeve as a crank to directly rotate the rope winch.

[0006] As a further improvement, both the connecting sleeve and the sleeve are provided with hexagonal holes that match the connecting rod. The sides of the connecting sleeve, the sleeve, and the connecting rod are all provided with pin holes. The connecting rod is inserted into the hexagonal hole and connected by a spring pin inserted into the pin hole.

[0007] As a further improvement, the connecting sleeve and the sleeve are provided with threaded holes, and the end of the connecting rod is provided with a screw. The connecting rod is connected to the connecting sleeve and the sleeve by threads.

[0008] As a further improvement, the lifting bracket under the seat cushion is a pneumatic rod device.

[0009] As a further improvement, the handle includes a connecting shaft with a handle glove on it, a connecting handle rotatably connected to the connecting shaft, and the handle glove having an anti-slip pattern.

[0010] Beneficial effects:

[0011] Flexible operation: This utility model adopts a purely mechanical design, and the rope tension can be adjusted by human power. It does not require power supply or hydraulic equipment support, and is particularly suitable for remote or energy-limited working environments.

[0013] Multifunctionality: The handrail has a detachable structure and can be used as a crank to directly rotate the rope winch, which facilitates tension adjustment and allows for quick switching of operating modes to meet various work needs.

[0014] High safety: The seat height can be adjusted by the gas spring lifting bracket to improve operator comfort; the handle is equipped with anti-slip pattern to ensure stable operation and reduce errors caused by slippery conditions.

[0015] Reliable connection: The connecting sleeve, sleeve and connecting rod of this utility model are designed with hexagonal fit and are fixed by spring pin or thread, so the connection is stable and reliable and effectively prevents loosening or falling off during high-load operation.

[0016] Adjustability: The structural parameters of the device (such as seat height, armrest position, etc.) can be flexibly adjusted according to the needs of the operator, further improving ease of use and work efficiency.

[0017] Economical and practical: Compared with electric or hydraulic drive devices, the purely mechanical design of this utility model significantly reduces production and usage costs, while also reducing maintenance costs caused by complex system failures. Attached Figure Description
