Abstract
The utility model discloses a rope-breaking automatic falling protection hook of a crane, which comprises a hook shell body 1 and a crown block 8 and a hook 9, and a rope-breaking self locking device is disposed in the hook shell body 1. The crane automatic falling protection hook can prevent the suspended object from falling, and has no assistant rope. The utility model has advantages of reasonable structure, convenient operation and low production cost, and can be widely used in departments such as the construction department.
Description
The utility model relates to the improvement of crane hook, the automatic anti-fall suspension hook of the disconnected rope of specifically a kind of hoisting crane.
At present, departments such as building engineering all use hoisting crane as the instrument that promotes article, with steel rope and suspension hook article be hung in crane jib below, the lifting of suspension is the realization that lifts by steel rope again, the reach of suspension with retreat and can realize that steel rope need be walked around a plurality of pulleys in the process of lifting by sliding before and after the pulley on the crane jib, because friction for a long time, fracture appears in steel rope easily, and this phenomenon that rope-breaking article weighs down will occur, and causes unnecessary loss or injures and deaths.And the crane hook that uses at present is made of pulley, suspension hook housing and suspension hook, can not stop the article tenesmus during wire cable rupture.The design people once designed the anti-fall file protect of a kind of hoisting crane suspension on April 5th, 2000, and its application number is 00214269.4, and this design needs file protect is arranged on the crane jib, and was added with secondary rope, and it is convenient inadequately to use, and made difficulty.
It is a kind of when wire cable rupture that the purpose of this utility model is to provide, and can not only stop the suspension tenesmus, and secondary rope need not be set, the automatic anti-fall suspension hook of the disconnected rope of the hoisting crane that manufacturing is installed easily, productive costs is low.
The utility model is achieved in that the automatic anti-fall suspension hook of the disconnected rope of this hoisting crane, is made of suspension hook housing and fixed pulley, suspension hook, and disconnected rope self-locking device is housed in the suspension hook housing.The automatic anti-fall suspension hook of the disconnected rope of this hoisting crane is also implemented by following measure: the disconnected rope self-locking device in the anti-fall suspension hook of the disconnected rope of this hoisting crane is made of disconnected rope self-locking jig, wedge block, promotion connecting rod, disconnected rope self-locking jig is established four, be fixed on symmetrically on the suspension hook inner walls, wedge block is established two, be fixed on suspension hook inner walls middle part, wedge block is connected with the end face of sliding cone in the corresponding disconnected rope self-locking jig in-to-in by promoting connecting rod respectively; Its disconnected rope self-locking jig is by the external fixation cone, interior sliding cone, the braking steel ball, locking spring, self-lock pin constitutes, the external fixation cone is fixed on the suspension hook inner walls, its inner chamber is cone-shaped, interior sliding cone middle part is a cylindrical cavity, to pass steel rope, its outer wall is the cone that adapts with the external fixation cone cavity, and on outer wall, establish three ball holes, place the braking steel ball in the ball hole, interior sliding cone is packed in the chamber of external fixation cone, and locking spring is pressed in interior sliding cone seat end, also establishes the self-locking tooth on the interior sliding cone outer wall, establish self-lock pin on the external fixation cone wall, self-lock pin is stuck on the self-locking tooth; Wedge block is made of wedge surface shell, movable rope sheave, slide block guide shaft, wedge surface shell retracing spring, slide block guide shaft seat portion is fixed on the interior adapter plate of suspension hook housing, the wedge surface outer cover suit of wedge block is on the slide block guide shaft, and by the support of wedge surface shell retracing spring, the turning cylinder of movable rope sheave is fixed on the end of wedge block wedge surface shell; The vertical top pull bar that promotes connecting rod is contained in the conduit, the oscillating axle bearing that promotes the transverse arm of connecting rod is fixed on the end wall of external fixation cone, the vertical rod of the end face of sliding cone passes in external fixation cone segments wall guide hole in pushing, and establishes retracing spring in the end of the vertical top pull bar that promotes connecting rod.When hoisting crane is in running order, because steel rope is the tension plumbness, this moment, movable rope sheave was compressed by steel rope, the wedge surface shell of wedge block is along slide block guide shaft compression wedge surface shell retracing spring, make the vertical top pull bar connecting terminal that promotes connecting rod be in wedge surface shell thickness, promote the connecting rod transverse arm and be in horizontality, the vertical rod that pushes interior sliding cone that promotes connecting rod then promotes the interior interior sliding cone of jig, locking spring is compressed, make the braking steel ball certain interval be arranged with passing between therebetween the steel rope, steel rope can freedom pass the disconnected self-locking jig of restricting up and down; When crane rope ruptures suddenly, because steel rope loses the pulling force of weight suddenly, this moment, the movable sheave of wedge block was not compressed, under the elastic force effect of wedge surface shell retracing spring, wedge block wedge surface shell is extrapolated along the slide block guide shaft rapidly, make the pull bar contact, vertical top that promotes connecting rod be in the thinnest some position of wedge surface shell, promote the connecting rod transverse arm and be in heeling condition, the vertical rod that promotes sliding cone in the pushing of connecting rod this moment then loses the roof pressure power to the interior sliding cone in the disconnected rope self-locking jig, interior sliding cone is under the elastic force effect of locking spring, outwards the cone tip part of fixed cone intracoelomic cavity moves rapidly, make braking steel ball chucking steel rope, and steel rope draws the tight more of card more, simultaneously, self-lock pin also in time snaps on the self-locking tooth, makes steel rope once more when the wedge surface shell of vertical direction tension compression wedge slide block, and disconnected rope self-locking jig still tightens steel rope.When mounted, in four disconnected rope self-locking jigs, top two opposite with following both direction, when right side rope was disconnected, lower right and upper left disconnected rope self-locking jig blocked the left side steel rope, strain weight; When left side rope was disconnected, lower left and top-right disconnected rope self-locking jig blocked the right side steel rope, the tension weight; When fixed pulley place wire cable rupture, two top disconnected rope self-locking jigs block left and right two steel ropes, the tension weight.
The utility model has the advantages that: compare with the automatic anti-fall suspension hook of present use, can not only stop suspension tenesmus, and secondary rope is not set, rational in infrastructure, easy to operate, productive costs is low.
