Abstract

The invention discloses a marine fixed sundry crane. The marine fixed sundry crane comprises a base (1), a lifting base (2), a rotary part (4), a rotary speed reducer (5), a lifting winch (6) and a pneumatic motor (7), wherein lifting base (2) is fixedly connected with the base (1); the rotary part (4) is connected with the lifting base (2) by a rotary support (3); the rotary speed reducer (5) is meshed with the rotary support (3); the lifting winch (6) is fixedly connected with the rotary part (4); a lifting steel wire rope (61) is wound on a coiling block of the lifting winch (6); a free end of the lifting steel wire rope (61) bypasses a fixed pulley (431) along the axial direction of the support rod (43); a movable block (432) is lifted; the end part of the free end is fixed on a fixed pin shaft of the support rod (43) and is connected with an input opening of the lifting winch (6); the pneumatic motor (7) provides power for the lifting winch (7). The sundry crane is driven by the pneumatic motor, and has the advantages of safety, reliability, concise and compact structure, low manufacturing cost, operation convenience and the like.

Description

technical field [0001] The invention relates to a crane, and in particular provides a marine fixed debris crane. Background technique [0002] In ships and marine engineering, deck cranes are mainly used for loading and unloading cargo, which are installed on the deck. The crane is a small lifting device used to hoist sundries such as production and living, and the crane is also installed on the deck. According to the needs of different materials in various areas of the ship, cranes of different specifications can be selected, which are collectively referred to as debris cranes. For example, fuel hose cranes used on large ships, Suez Canal light cranes, pump room cranes, boatswain warehouse cranes, steering gear room cranes, food cranes, and sludge cleaning cranes are all sundry cranes. Food cranes and light movable debris cranes used on small ships are also debris cranes. These hoists have their own specific purpose and can also be used to lift nearby debris. According ...
