Abstract
The invention discloses a telescopic crane for a ship. A tower body is arranged on a base and is articulated with a basic boom; the basic boom is provided with a crane winch for hoisting the basic boom; a luffing oil cylinder is arranged between the basic boom and the tower body; the basic boom is connected with a retractable telescopic boom; a lifting hook is arranged at the end of the telescopic boom and the basic boom is provided with a telescopic controller which is used to control the telescopic movement of the telescopic boom. By adopting the design of the telescopic boom, the telescopic crane for the ship, which has large working radius and large hoisting height, is arranged on the ship deck in the limited deck space of the ship, the outline structure of the crane is optimized, a relatively small deck space is occupied and multiple engineering operations can be realized.
Description
Technical field
The present invention relates to elevator machinery field, particularly a kind of telescopic crane peculiar to vessel.
Background technology
Telescopic crane peculiar to vessel is a kind of of deck crane tool.Deck crane is to carry out a kind of special hoisting crane of hauling operation at sea in environment, is mainly used in the vital tasks such as transportation transfer, the replenishment at sea of goods between naval vessel, the input of under-water operation equipment and recovery.Marine special applied environment has brought very large challenge to the control of deck crane.On the one hand, the similar land various crane equipment of owing to drive, needs the swing that produces in control load transportation, guarantees its positioning precision and conveying efficiency; On the other hand, because this hoisting crane is fixed on the motion platforms such as boats and ships, the sport of platform itself produces strong impact to load movement, and in a lot of situation, load lifting and the motion conditions at place, level point and the motion of crane itself are inconsistent.Particularly, in the course of the work, crane ship and taken-over vessel can be with wave pitching, rolling and heaves, and these motions will cause load to swing; Particularly in lifting process, this type games of boats and ships easily causes the load of having sling again to be bumped against with deck, or makes to put down but not yet to depart from the load of suspension hook again unsettled, and these all can threaten the safety of operation.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of telescopic crane peculiar to vessel, its objective is, provide a kind of compact conformation, the telescopic crane peculiar to vessel that the resource that takes up room is little.
For achieving the above object, technical scheme of the present invention is as follows:
Telescopic crane peculiar to vessel, tower body is arranged on base, tower body is hinged with basic arm, on basic arm, be provided with the winch that hoists of the basic arm that hoists, between basic arm and tower body, be provided with amplitude oil cylinder, described basic arm is connected with telescopic telescopic boom, and the end of described telescopic boom is provided with suspension hook, is provided with the expansion controller of controlling telescopic boom fore and aft motion on basic arm.
Further, on described base, be provided with centre collector ring, comprise slip ring group, slip ring frame and dowel disc thereof, carbon piece group, carbon piece frame and dowel disc, turntable connecting device, insolator disc, terminal pad and supporting seat, turntable connecting device is a universal drive shaft, its upper end is fixedly connected with span winch turntable lower surface, and lower end is fixedly connected with slip ring upper driving terminal pad.
Further, on described tower body, be provided with swing type mechanism, comprise on the upper bracket described in upper bracket and lower bracket and be fixed with motor, motor is by hydraulic coupler connection rotating shaft, rotating shaft cross-under has flange, flange outer is provided with step disk, and rotating shaft one end is connected with rotary reducer, and rotary reducer is connected with output gear.
Pass through technique scheme, a kind of telescopic crane peculiar to vessel provided by the invention, adopt the design of telescoping boom, on hull in limited between deck space, by a large swinging radius, the telescopic crane peculiar to vessel of big elevating height is arranged on deck in ship structure, has optimized this crane configuration, take less deck empty, can realize the feature of various engineering operation.
