Abstract
The utility model discloses a telescopic sleeve type anti-swing device for a ship-mounted crane, which comprises a lifting lug, a first layer sleeve, a second layer sleeve, a connecting rib, a lifting disc and a hook, wherein the device is fixedly connected onto the suspension arm of the crane through the lifting lug, and meanwhile, a hydrocylinder is mounted between the device and the suspension arm of the crane; when the amplitude of the suspension arm of the crane is changed, the angle between the device and the suspension arm is adjusted through the expanding and contraction of the hydrocylinder, so as to enable the device to be in a vertical downward state all the time. A steel wire rope passes through from the middles of the first layer sleeve and the second layer sleeve and is fixedly connected with the middle of the lifting disc; the lower part of the lifting disc is fixedly connected with the hook; during load lifting and dropping, the second layer sleeve can expand and contract in the first layer sleeve, so that the swing of the steel wire rope is limited and the movement of the load in the vertical direction is not influenced.
Description
Technical field
The invention discloses a kind of deck crane telescopic type anti roll device, belong to the anti-technical field of shaking of hoisting crane.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, claims again crane, belongs to material carrying machine.Conventionally, elevator machinery is by lifting mechanism (making load up-and-down movement), operating unit (elevator machinery is moved), luffing mechanism and swing type mechanism (making load make parallel motion), add metallic magnetism, engine installation, handles control and necessary auxiliary device combines.The work characteristics of hoisting crane is to do intermittent, cyclicity motion, a working cycle comprises: load-engaging device is mentioned load from getting thing, is then moved horizontally to appointed place and falls load, then carries out counter motion, make load-engaging device reposition, to circulate next time.In general, hoisting crane hangs load by steel rope, suspension hook, by lifting mechanism, carries out lifting, by luffing mechanism and swing type mechanism, carries out parallel motion.Because steel rope belongs to compliant member, when carrying out luffing, gyroscopic movement, load will be made simple harmonic motion, and this can increase the time of task difficulty and working cycle.Particularly for deck crane, impact due to Marine Environment Factors such as wind, wave, streams, boats and ships can produce rolling, pitching, yawing, swaying, surging, hang down and swing six-freedom motion, and this has just more aggravated waving of load, when sea situation is severe, almost cannot carry out operation.For hoisting crane, hang thing and wave problem, adopt at present conventionally Maryland rigging mechanism, comprehensive compensating device to solve, but its mechanism and control all more complicated.
Summary of the invention
In order to overcome the weak point in background technology, the present invention proposes deck crane telescopic type anti roll device.
In order to achieve the above object, the technical solution used in the present invention is:
A deck crane telescopic type anti roll device, is characterized in that: this device comprises hanger, ground floor sleeve pipe, second layer sleeve pipe, dowel, hanging scaffold, suspension hook.Hanger top is fixed on crane arm, and bottom is fixed on ground floor sleeve pipe, and there is hinge arrangement centre, and telescopic type anti roll device can be rotated around arm hitch point; Ground floor sleeve pipe is tubular type structure, and its inwall is coated with grease, and steel rope is from its middle passing through; Ground floor sleeve pipe bottom is second layer sleeve pipe, and second layer sleeve pipe is also tubular type structure, and steel rope is from its middle passing through, and its upper end puts in ground floor sleeve pipe, can in ground floor sleeve pipe, slide up and down; Second layer sleeve pipe bottom is connected with hanging scaffold by dowel, and steel rope is fixed on hanging scaffold center, and hanging scaffold bottom is fixed on suspension hook.Sleeve pipe number and the size thereof of telescopic type anti roll device are determined according to hoisting crane actual conditions, are not limited to two-layer.
A kind of deck crane telescopic type anti roll device, its rocking-prevention function mainly waves to realize by ground floor sleeve pipe, second layer sleeve pipe restriction steel rope, specific implementation approach is: (1) installs hydraulic ram between telescopic type anti roll device and crane arm, when crane arm luffing, by the angle between hydraulic ram telescopic adjustment telescopic type anti roll device and arm, make telescopic type anti roll device all the time in state straight down; (2) fall while putting load, load meeting hauls suspension hook, hanging scaffold, second layer sleeve pipe and moves downward, and second layer sleeve pipe stretches out ground floor sleeve pipe; (3), while promoting load, steel rope can carried hanging scaffold, second layer sleeve pipe upward movement, second layer cannula retraction ground floor sleeve pipe.
The present invention compares with background technology, has useful effect to be:
(1) adopt telescopic type anti roll device, owing to there being waving of sleeve pipe, second layer sleeve pipe restriction steel rope, the hunting of load problem that can avoid the flexibility due to steel rope to cause;
(2) use hydraulic ram to regulate the angle between telescopic type anti roll device and crane arm, can make telescopic type anti roll device all the time in vertical state, in the time of can avoiding Ship Swaying, telescopic type anti roll device is subject to athwartship moment;
(3), with respect to Maryland rigging mechanism, comprehensive compensating device, telescopic type anti roll device structure and control are simple.
