Abstract
The invention discloses a rope guide of a hoisting mechanism of a crane, relating to a hoisting mechanism of a large-hoisting height crane, and solving the problem that the winding in or winding out of a steel rope on a winding drum is limited by a deflection angle. The rope guide is characterized in that a winding drum chain wheel is arranged on an output shaft of the winding drum and drives a drive chain wheel through a winding drum chain, a speed reducer and a universal coupling and further drives a chain; a rope guide pulley gear is fixed on the chain and is in rolling matching with a bracket; and horizontal guide pulley wheels are respectively arranged below two ends of the winding drum and vertical to pulley wheels of the rope guide pulley gear. The speed ratio of the speed reducer and the diameters of the winding drum chain wheel and the drive chain wheel are matched with the distance that the winding drum cylinder rotates for one circle and the rope guide pulley gear moves one pitch along the axle line. The winding of the steel rope is not limited by the deflection angle, thus the winding drum can be made longer, and the requirement for the large hoisting height is met.
Description
Technical field
The present invention relates to the lifting mechanism of big elevating height hoisting crane, particularly the steel rope rope guide in the twin-laminate roll system for winding in the same way.
Background technology
" in the rubber tyre gantry crane design handbook (calendar year 2001 is published by China Railway Press),, adopt bilayer or multilayer steel rope reel system usually to the lifting mechanism of big elevating height hoisting crane.And in double-deck or multilaminate coiled system, for guarantee steel rope can be in marshalling under the free state, do not job-hop, drift angle when steel rope moves on reel or lays out requires to be not more than 2 °, makes steel rope marshalling on reel otherwise need to install rope guide.
The rope guide of existing crane hoisting mechanism is two-way or unidirectional screw-rod structure, because above-mentioned rope guide does not change the direction of steel rope, so steel rope moves into or still be subjected to the restriction of sail angle (" hoist design specification " regulation: the angle that the steel rope line of centers departs from reel plug helix line of centers both sides should be greater than 3.5 °) when laying out reel.At this moment owing to limited by the drift angle, the length of reel can not increase, and then needs to increase volume and satisfies big elevating height lifting mechanism layout requirement in the footpath simply, so also just makes the stressed increase of retarder, the deadweight that has increased whole lifting mechanism.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of rope guide of crane hoisting mechanism is provided, be not subjected to any restriction of drift angle in the time of can making the steel rope of big elevating height crane hoisting mechanism on reel, move into or lay out.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of rope guide of crane hoisting mechanism, comprise reel, and with reel bonded assembly steel rope, it is characterized in that: described rope guide is by the reel sprocket wheel, the reel chain, retarder, universal coupling, drive sprocket, chain, the row's rope pulley device that constitutes by two pulleys that are arranged side by side, support, and the horizontally-guided pulley is formed, described reel sprocket wheel is installed on the shaft of described reel, by described reel chain, retarder, universal coupling drives described drive sprocket, and then drive described chain, described row's rope pulley device is fixed on the described chain, and described row's rope pulley device rolls with support and cooperates; The pulley of the below at described reel two ends, vertical described row's rope pulley device is provided with described horizontally-guided pulley respectively.
The diameter of the speed ratio of described retarder and described reel sprocket wheel, drive sprocket should be complementary along the distance that axis moves a pitch with the reel row's rope pulley device that rotates a circle.
The present invention compared with the prior art, in the same way twin-laminate roll around two steel ropes change direction vertically downward into opposite two horizontal directions around the back of getting off by row's rope pulley device from the reel, rather than can't change the direction of steel rope as the rope guide of prior art.Steel rope raps around on the fixed pulley that is positioned at the reel below by leading sheave after changing horizontal direction into again, reels between fixed pulley and lifting hook pulley group then.The coiling of steel rope is not subjected to the restriction of drift angle like this, and that reel can be done is longer, satisfies the requirement of big elevating height.

The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As Fig. 1,2,3,4,5, shown in 6, a kind of rope guide of crane hoisting mechanism, comprise reel 9, and with reel 9 bonded assembly steel ropes 10, described rope guide is by reel sprocket wheel 1, reel chain 2, retarder 3, universal coupling 4, drive sprocket 5, chain 6, the row's rope pulley device 7 that constitutes by two pulleys that are arranged side by side, support 8, and horizontally-guided pulley 11 is formed, described reel sprocket wheel 1 is installed on the shaft of described reel 9, by described reel chain 2, retarder 3, universal coupling 4 drives described drive sprocket 5, and then drive described chain 6 and carry out straight-line motion, described row's rope pulley device 7 is fixed on the described chain 6, described row's rope pulley device 7 rolls with support 8 and cooperates, and chain 6 traction row rope pulley devices 7 carry out straight-line motion on support 8; The below at described reel 9 two ends, the pulley of vertical described row's rope pulley device 7 are provided with described horizontally-guided pulley 11 respectively.
The coupling of speed ratio and each sprocket diameter by retarder 3 guarantees when reel 9 rotates a circle, and row's rope pulley device 7 is along the axis distance of a mobile pitch just in time.
In the same way twin-laminate roll around two steel ropes 10 change direction vertically downward into opposite two horizontal directions around the back of getting off by row's rope pulley device 7 from the reel 9, steel rope 10 raps around on the fixed pulley 12 that is positioned at reel 9 belows by horizontally-guided pulley 11 after changing horizontal direction into again, reels between fixed pulley 12 and lifting hook pulley group 13 then.The coiling of steel rope is not subjected to the restriction of drift angle like this, and that reel 9 can be done is longer, satisfies the requirement of big elevating height.
Working process of the present invention:
The driving power of row's rope pulley device 7 is provided by reel 9, and when reel 9 forward and reverse rotations, row's rope pulley device 7 is done the horizontal linear crank motion.During installation, steel rope 10 is involved in or rolls out the position of reel on the midway location aligning reel 9 of two pulleys in row's rope pulley device 7.When reel 9 rotations, drive is installed in reel sprocket wheel 1 rotation on reel 9 shafts, thereby drive reel chain 2, retarder 3,5 rotations of universal coupling 4 drive drive sprockets, drive sprocket 5 rotations drive chain 6 and carry out straight-line motion, because row's rope pulley device 7 is fixed on the chain 6, then arranges rope pulley device 7 and do straight-line motion on support 8.The coupling of speed ratio and each sprocket diameter by retarder 3, guarantee when reel 9 rotates a circle, row's rope pulley device 7 just in time moves the distance of a pitch along axis, and then steel rope 10 is consistent with the position of row's rope pulley device 7 all the time around the position of going into or laying out reel 9.During the forward and reverse rotation of reel 9, the steel rope 10 that twines on the reel 9 around go into or lay out reel after directly on the pulley of going into to arrange rope pulley device 7.Twin-laminate roll around two steel ropes 10 change downward direction into opposite two horizontal directions around two pulleys of back that get off from the reel 7 by row's rope pulley device 7, rap around to again on the fixed pulley 12 that is positioned at reel 7 belows by two horizontally-guided pulleys 11 then, between fixed pulley 12 and lifting hook pulley group 13, reel then.
