Description

Jib-type crane container spreader stabilizer
Technical field
The present invention relates to a kind of jib-type crane suspender, particularly relate to a kind of jib-type crane container spreader steady Determine device.
Background technology
General jib-type crane, such as gantry crane, wheel-mounted crane etc., frequently with simple container spreader lifting collection Vanning, suspender passes through four steel wire hangs on suspension hook.During operation, by manually by the rotation lock alignment container top of suspender Four corner casting holes.Due to single-point lifting, during container hanging, owing to revolution and the luffing of crane arm support move, Container will rotate and dancing.If only self damping by simple container spreader steel rope system consumes collection The rotation of vanning and swing energy, then to take an undesirably long time, directly affect crane job efficiency;If manually come Righting container, then there is hidden danger in the personal safety of workman, efficiency is also low.
Content of the invention
It is an object of the invention to provide a kind of jib-type crane container spreader stabilizer can be in lifting container mistake Journey reduces rotation, swing and the stable set vanning of container.
The present invention realizes that the technical scheme of above-mentioned purpose is:
Including pulley, counterweight bracing frame pulley in the middle part of motor, electromagnetic clutch, reel, counterweight, counterweight bracing frame, jib Group, upper leading block, lower leading block, counterweight assembly pulley, left haulage cable, right haulage cable, driving steel wire rope.Counterweight Sliding up and down in counterweight bracing frame, counterweight is connected with container spreader by left haulage cable, right haulage cable, Zuo Qian Draw steel wire rope, one end of right haulage cable is connected respectively on two angle points on the long limit of container spreader, the other end rotating around Cross pulley in the middle part of jib, counterweight bracing frame assembly pulley, counterweight assembly pulley, be fixed on counterweight bracing frame.When under container spreader During fall, drive counterweight upward sliding by haulage cable;When container spreader rises, counterweight is under the Action of Gravity Field of self Slide downward.Motor is connected with reel by electromagnetic clutch, and reel is fixed on crane rotation platform, and reel wrapped around The driving steel wire rope of a piece one-in-and-one-out, i.e. during spool turns, drives steel wire rope one end around entering reel, the other end from reel around Going out, leading block is walked around at the two ends of this root driving steel wire rope, lower leading block is connected respectively to the upper and lower of counterweight.When When motor is rotated by electromagnetic clutch band movable reel is forward and reverse, the driving steel wire rope on reel drives counterweight to move up and down.
By such scheme, described counterweight bracing frame is fixed on crane rotation platform, and counterweight bracing frame assembly pulley sets On counterweight bracing frame top, upper leading block and lower leading block are respectively installed in the upper and lower of counterweight bracing frame.
The invention has the beneficial effects as follows: owing to have employed counterweight, the haulage cable being connected on container spreader is to packaging There is a pulling force effect inwards at two angles of box hanger, to the rotation of container with swung certain interception, can reduce The rotation of container, swing and stable set vanning, improve crane job efficiency, and security is good.
Brief description
Fig. 1 is the structural representation of the present invention.
The wirerope-winding schematic diagram of Fig. 2 present invention.
In figure: 1. crane rotation platform, 2. descend leading block, 3. reel, 4. drive steel wire rope, 5. go up leading block, 6. counterweight bracing frame, 7. hoist rope, 8. counterweight bracing frame assembly pulley, 9. counterweight assembly pulley, 10. counterweight, 11. gib arms of crane Frame, 12. right haulage cables, 13. left haulage cables, 14. container spreaders, 15. containers, 16. motors, 17. electromagnetism from Clutch, pulley in the middle part of 18. jibs.
Detailed description of the invention
As follows to the detailed description of the invention in conjunction with accompanying drawing:
Including pulley the 18th, counterweight in the middle part of motor the 16th, electromagnetic clutch the 17th, reel the 3rd, counterweight the 10th, counterweight bracing frame the 6th, jib Bracing frame assembly pulley the 8th, upper leading block the 5th, lower leading block the 2nd, counterweight assembly pulley the 9th, left haulage cable the 13rd, right haulage cable 12nd, steel wire rope 4 is driven.
One end of right haulage cable 12 and left haulage cable 13 is connected respectively to two of the long limit of container spreader 14 On angle point, the other end walks around pulley the 18th, counterweight bracing frame assembly pulley the 8th, counterweight assembly pulley 9 in the middle part of jib respectively, is fixed to counterweight On bracing frame 6.Motor 16 is connected with reel 3 by electromagnetic clutch 17, and reel 3 is fixed on crane rotation platform 1, reel Wrapped around the driving steel wire rope 4 of two end one-in-and-one-outs on 3, drive end on steel wire rope 4 to walk around lower leading block 2 and be connected to The top of counterweight 10;4 times ends of steel wire rope are driven to walk around the bottom that leading block 5 is connected to counterweight 10.
Counterweight bracing frame 6 is fixed on crane rotation platform 1, and counterweight bracing frame assembly pulley 8 is located on counterweight bracing frame 6 Portion.
The course of work of the present invention is such that
In motor 16 power-off, i.e. electromagnetic clutch 17 separates, and now counterweight 10 slides up and down in counterweight bracing frame 6 and is not subject to In the case that reel 3 controls: when packaging suspender 14 declines, by right haulage cable 12 and left haulage cable 13 by counterweight 10 It is lifted up;When packaging suspender 14 rises, counterweight 10 slide downward under self gravitation effect.When crane arm support 11 inwardly becomes During width braking, due to by be connected with counterweight 10 right haulage cable 12 and left haulage cable 13 to 14 two angles of packaging suspender Having individual pulling force effect inwards, container 15 amplitude of oscillation reduces;With should crane arm support 11 outside luffing braking, due to be subject to In pulling force effect, container 15 can quickly stop swinging.When container 15 rotates towards (vertical view container) clockwise, left Haulage cable 13 is driven elongation by container spreader 14, and counterweight 10 is lifted up, and right haulage cable 12 relaxes, counterweight complete Portion's weight is supported by left haulage cable 13, and left haulage cable 13 pulling force increases, and forces container 15 to rotate towards reverse direction; In like manner, when container 15 is towards when rotating counterclockwise, right haulage cable 12 forces container 15 to rotate toward the clockwise direction, is leading The rotation of container 15 is effectively and rapidly reduced under the reciprocating drawing steel wire rope 12 and 13.
When in lifting shipping process, owing to operator's Rough operation or other factors cause container significantly When swinging and rotate, now depending automatically adjusting of counterweight 10 alone very slowly just will can make container 15 stable.At this moment electricity can be allowed Machine 16 obtains electric, and now electromagnetic clutch 17 is also at engagement state, and motor 16 carries movable reel 3 to rotate clockwise, by driving steel The lower end of cord 4 pulls counterweight 10 slide downward so that right haulage cable 12 and left haulage cable 13 to container The pulling force inwards of suspender 14 constantly increases so that container 15 quickly settles out;After container 15 settles out, Motor 16 carries movable reel 3 to rotate slowly counterclockwise, makes counterweight 10 slowly slide up by driving two ends up and down of steel wire rope 4 Dynamic, until container 15 is maintained in correct attitude.Then just can cut off the power supply to motor 16, by counterweight 10 from Main effect carrys out stablizing of domination set vanning 15.
