Description

The long adjustable fixed crane of rope

Technical field

This utility model relates to suspender, particularly relates to the long adjustable fixed crane of a kind of rope.

Background technology

The type of drive of crane has two classes substantially: one is centralized driving, i.e. drives long power transmission shaft to drive with a motor The adhesion wheel on both sides；Two for drive respectively, and i.e. the adhesion wheel on both sides is respectively by a motor-driven.Medium and small bridge-type is hung Car more employing brake, decelerator and motor unit incorporated " three-in-one " type of drive, the common bridge of big elevating capacity Formula crane is for ease of installing and adjusting, and driving means is frequently with Hooks coupling universal coupling.China Patent No. be 2012203736371, Authorization Notice No. is CN202785379, i.e. disclose a kind of crane in the patent document of entitled " frock crane ".Crane includes Suspension bracket and hanging hook assembly, suspension bracket includes stand and crossbearer, and hanging hook assembly is fixed in crossbearer, and stand is provided with road wheel, and crossbearer is hinged Between stand, crossbearer and stand, it is additionally provided with the lift cylinders driving crossbearer to swing, during use, drives crossbearer to swing by lift cylinders And realize the lifting of suspension hook, thus realize slinging object in putting down.Hanging hook assembly includes suspension hook, and the version of suspension hook has Two kinds: one is enclosed, it is adaptable to is hooked on rope or bar and hangs, there is will not produce that object deviates from from suspension hook excellent Point, Chinese Patent Application No. be 2012103227376, publication No. be CN103663123A, the patent of entitled " suspension hook " literary composition Part i.e. discloses a kind of enclosed suspension hook；Another kind is open, is i.e. adapted to be hooked on all of object and hangs, Therefore there is the advantage that versatility is good.Chinese Patent Application No. be 2013104512146, publication No. be CN103466435A, The patent document of entitled " lifting hook of steel plate " i.e. discloses a kind of open suspension hook.Although existing open suspension hook has But the advantage that versatility is good lose the object that enclosed hook had be not easy from suspension hook the advantage of landing, i.e. when Object landing phenomenon is the most easily produced (and when the object that length is big is hung by the two ends that be hooked in object when suspension hook tilts bigger Time, suspension hook can be in the state that inclination angle is bigger).The most existing open suspension hook is restricted by connection sometimes and is connected to one in pairs Rising and constitute hanging hook assembly, article are lifted by the two ends being hooked in article by two suspension hooks during use, and the suspension hook of this structure is total Become to have the disadvantage that the stress connecting rope when Item Weight keeps constant can increase along with the growth of article, thus lead Cause easily to produce phenomenon of rupture during the article hanging length length.Existing crane is sling and is easily produced mobile phenomenon during article The phenomenon drawn close towards stand with the object being lifted, namely the object being lifted during slinging except produce lifting fortune Dynamic outer also can produce translational motion, translational motion is easily caused rocking thus easily colliding the object, therefore of periphery of article Poor stability；The apparent volume of suspension bracket is huge, inconvenience when using in small space；Lifted by cylinder, easily produce and drip Leakage phenomenon and lifting distance are little.

Utility model content

First purpose of the present utility model aims to provide a kind of can adjustment and restricts long and change the rope of the stress connecting rope Long adjustable fixed crane, solve existing hanging hook assembly rope length non-adjustable and cause the article hanging length length time easy The problem producing phenomenon of rupture.

Second purpose of the present utility model further provides for one on the basis of being intended to first utility model purpose and slings During object object be not easy produce shaking phenomenon, simple in construction, clasp joint article time be not easy produce landing phenomenon rope length adjustable Fixed crane, solve existing crane sling object time object to produce shaking phenomenon, apparent volume huge and uncomfortable Use for narrow space, easily produce weeping and lifting distance is little, the problem of object easy landing when using.

More than technical problem is that and solved by following technical proposal: the long adjustable fixed crane of a kind of rope, including hanging Frame and hanging hook assembly, it is characterised in that also including wire spool and the lifting motor driving wire spool to rotate, described suspension bracket includes standing Bar and cross bar, the lower end of described vertical rod is provided with installing plate, and described installing plate is provided with bolt hole, and one end of described cross bar is connected to The upper end of described vertical rod, described lifting motor and wire spool be fixed on the other end of described cross bar, and described hanging hook assembly includes hanging Hook, appending disk and two ends are passed down through the connection rope of appending disk, and described suspension hook is stainless steel structure, and the two ends of described connection rope are all Connect and have described suspension hook, the threaded one end of described elevating lever connect have be rotationally connected with described appending disk driven gear, another End is provided with jaw, and described elevating lever the most liftably links together with described appending disk, and described jaw is supported on described connection The middle part of rope, described driven gear engagement driving gear, described driving gear is provided with drive shaft, and described drive shaft is provided with gripping Bar, described appending disk is linked together with described wire spool by hoist cable.During use, passed on installing plate by foundation bolt Bolt hole and realize installation of the present utility model, then two suspension hooks are hooked in the two ends of article, are driven by lifting motor Wire spool rotates and realizes the lifting of suspension hook, and object is risen by suspension hook.Due to by by hoist cable around by the way of realize object Lifting, the horizontal movement that therefore during lifting, object produces is little, thus is not easy generation and rocks；Suspension bracket is made up of cross bar, vertical rod, Compact conformation, take up room little and intensity good, it is possible to be applicable to installing and using of small space；Lifted by motor, no Weeping can be produced, clean environment firendly and disclosure satisfy that the lifting requirement of big distance.Use then on carry appending disk and realize by Article have been carried.When object length changes, rotating drive shaft by hold holding rod, drive shaft drives driving gear to rotate, Driving gear drive driven gear rotate, driven gear drive lifter rod lifting, lifter rod lifting and make connect rope lifting and Change the length connecting rope between appending disk and suspension hook so that the angle connected between this part same level direction of rope changes Change to keep constant so that the stress connected when being fallen the change of Item Weight constant only length is constant, overcome rope to rupture Phenomenon.
