There is a type of marine pneumatic winch on the market, whose overall structure is too complex, making installation and use inconvenient. It cannot be installed or disassembled at any time, and is not suitable for various ships and the different operating environments of supporting equipment. Therefore, it is necessary to develop a new type of marine pneumatic winch to address the aforementioned issues of electric mooring winches and hydraulic mooring winches, saving energy and space.
Currently commonly used on shipsPneumatic winchThere are electric pneumatic winches or hydraulic onesPneumatic winch, both have some unavoidable drawbacks, such as the electric mooring winch being prone to fire when the motor starts or stops; hydraulic mooring winches have unavoidable issues with hydraulic oil leakage and significant pollution. In addition, both electric and hydraulic mooring winches require additional power sources, are prone to damage under overload, and can cause mechanical failures. Furthermore, there are issues such as large size and weight, taking up significant space on the ship. However, the compressed air system present on all ships usually includes an air compressor, pressure switch, transmission pipelines, and terminal control valves, with the transmission pipelines covering almost all corners of the ship. There is a type of marine winch on the marketPneumatic winch, the overall structure is overly complex, installation and use are inconvenient, it cannot be installed and disassembled at any time, and it is not suitable for various ships and the various operating environments of supporting equipment. Therefore, it is necessary to develop a new type of marine winchPneumatic winchto solve the above problems of electric and hydraulic mooring winches, saving energy and space.
In response to the shortcomings of existing technology, technicians have provided a compact winchPneumatic winch, to address the issues of overly complex overall structure, inconvenient installation and use, inability to install and disassemble at any time, and unsuitability for various ships and supporting equipment in various operating environments. To achieve the above objectives, it is realized through the following technical solution: a compact winchPneumatic winch, including a first fixed seat and a second fixed seat, the inner cavities of the first and second fixed seats are rotatably connected to a winding drum; the left side of the left mounting seat is fixedly connected to a pneumatic motor; the right end of the pneumatic motor's piston rod sequentially passes through the left mounting seat and the first fixed seat and extends into the inner cavity of the first fixed seat.
Wherein, the right end of the pneumatic motor's piston rod is fixedly connected to the left side of the winding drum, the right side of the first fixed seat is fixedly connected to a connecting rod, and one end of the connecting rod away from the first fixed seat is fixedly connected to the left side of the second fixed seat. The surface of the first fixed seat is provided with two symmetrically distributed connecting rods. The right side of the second fixed seat is fixedly connected to a limiting frame. The inner cavities of the first and second fixed seats are both provided with mounting threaded holes. The bottom of the first and second fixed seats is respectively provided with two symmetrically distributed mounting screw holes.
Compared with existing technology, this new type of winchPneumatic winchhas beneficial effects: due to optimized design and construction, this winchPneumatic winchis installed on a plane through mounting threaded holes, mooring cables are installed through through holes and limiting holes, and then the pneumatic motor is started to drive the winding drum to rotate, retracting the mooring cables for operation; therefore, it has a compact structure, more stable power transmission, can adapt to various ships and supporting equipment in various operating environments, and has higher adaptability.
