Embodiment Construction

[0011] With reference to the accompanying drawings, figure 1 Among them, the worm is driven by the hydraulic motor 4, and the worm drives the turbine to rotate, so that the worm reducer 3 drives the main transmission gear to rotate. When the boom is displayed, the two transmission gears move at the same time, the small main transmission gear 7 rotates, thereby driving the small stroke rack 8 to move, and the mobile frame 2 moves, and at the same time, the large main transmission gear 6 rotates, thereby driving the large stroke rack 9 moves, thus drives the telescopic boom 1 to move, and the movement stroke of the large gear is twice that of the small gear, thereby realizing the large-stroke extension of the boom.

Abstract

The invention discloses a horizontal telescopic suspension arm of a skiff telescopic device. The horizontal telescopic suspension arm is formed by a turbine worm reducer, a gear, a gear rack, a rack, a hydraulic motor and the like. The suspension arm is provided with a two-stage telescopic structure, and the extension for two routes can be realized. The structure is provided with a safety valve, thus the suspension arm can be guaranteed to safely stop at any position; and when a power supply is in power failure, the safety valve can automatically lock, and the happening of an accident is avoided. When in an emergency situation, the suspension arm can be driven by an accumulator which is provided with a nitrogen gas bag, and the full flexibility of the suspension arm can be realized.

Description

(1) Technical field [0001] The invention relates to a device installed on small boats equipped for ships and offshore working platforms for crew members' emergency escape and daily work, which belongs to the shipbuilding technology, and specifically relates to a small boat release mechanism. (2) Background technology [0002] In the case of high sea conditions and speed-launching boats, it is a condition to ensure the safety of the mother ship that the small boat retracting device can be installed implicitly. But at present, domestic hooks are basically unable to realize fast retraction, launch and implicit installation of the boat. (3) Contents of the invention [0003] In order to solve the above-mentioned limitations, the present invention designs a novel horizontally telescopic boom of a small boat retractable device to realize concealed installation. [0004] Its technical principle is: the boom structure is in the form of a frame, which is a welded structure of high...
