Description

Technical Field

[0001] This utility model relates to the field of pneumatic winch technology, and in particular to a pneumatic winch for underwater use. Background Technology

[0002] A pneumatic winch is a device that uses a blade-type pneumatic motor as its power source and transmits power to a drum via a planetary gear reducer to lift heavy objects. The pneumatic winch motor and reducer are connected to both sides of the drum, making the winch small in size, light in weight, compact in structure, simple to operate, and easy to maintain. It can achieve stepless speed regulation within a certain range. The winch is braked by a motor, which is reliable. It can also be operated manually without compressed air and is widely used in underwater operations, such as marine resource exploration, underwater facility installation and maintenance, etc. Winches are often used to retrieve and deploy ropes, cables and other components to achieve operations such as lifting, casting and pulling underwater equipment or objects.

[0003] According to the pneumatic winch base proposed in announcement number CN220337871U, a first handwheel rotates a first screw, which drives a first guide block to move laterally within a first adjusting groove. The first guide block drives a second mounting seat to move laterally away from or closer to the first mounting seat, thus adjusting the distance between the first and second mounting seats. When the second mounting seat moves laterally, a first and second telescopic sleeve can drive a fourth mounting seat to move laterally away from or closer to a third mounting seat, thus adjusting the distance between the fourth and third mounting seats. This facilitates the adjustment of the spacing between the two first arc-shaped grooves and the two second arc-shaped grooves, making it convenient to install pneumatic winches of different widths on the first, second, third, and fourth mounting seats.

[0004] When existing pneumatic winches are used in underwater operations, they need to be installed on ships. However, different models of pneumatic winches require corresponding mounting bases for fixation, which lacks universality. This means that every time a pneumatic winch is replaced, the base needs to be reinstalled on the ship, increasing equipment procurement and maintenance costs, as well as operational difficulty and time costs.

[0005] Therefore, there is an urgent need to provide a pneumatic winch for underwater use to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pneumatic winch for underwater use.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an underwater pneumatic winch, including a pneumatic winch body, wherein a winch support is fixedly installed at the bottom end of the pneumatic winch body;

[0008] The winch support is provided with a mounting base for fixing to the ship below. First transverse guide rails are fixedly installed on both sides of the top of the mounting base, and a cross guide rail is fixedly installed on the top of the mounting base.

[0013] With the above technical solution, one second transverse slider drives another second transverse slider to move through two first transverse adjusting rods and a second transverse adjusting rod, and the two first transverse adjusting rods and the second transverse adjusting rod respectively drive two second transverse guide rails to move accordingly.

[0014] The present invention is further configured such that: a first cylinder is fixedly installed on one side of the cross guide rail, a first L-shaped plate is fixedly installed on one end of the piston rod of the first cylinder, and one end of the first L-shaped plate is fixedly connected to a second transverse slider on one side.
