Abstract
This invention relates to a guide and rotation machine of lift sling, which comprises guide mechanism, rotation mechanism and crossbeam; it has following peculiarities: a) guide mechanism is formed by cruciform girder, steel rope and block device disposed vertically on the small carriage; b) the steel ropes circling down from the block device of heize mechanism are connected with four girder ends of cruciform girder separately to form a crisscross to position the cruciform girder at parallel and vertical direction; c)the rotation mechanism mounted in the cruciform girder is connected with sling crossbeam.
Description
Technical field
The invention belongs to handling machinery, be specifically related to a kind of guiding and rotating mechanism of crane hanger.
Background technology
The crow crane that uses in the smelter, shown in Figure 1, suspender rotation, the guiding mechanism form continued to use since the fifties have top dolly 01, bottom dolly 02, guide frame 03 and suspender 04 always.Hoisting crane top dolly is equipped with hoisting of suspender and tilting mechanism, can realize suspender hoist and claw is tumbled, the top dolly links to each other with the bottom dolly by circular orbit, thereby realizes that suspender rotates at any angle, and the track adjusting wheel that is installed on the guide frame leads to the action of tumbling.The bottom dolly is realized the operation of dolly along the span direction.This crow crane complex structure, the dolly whole height is higher, and the operational space of suspender is less, and complete vehicle weight is big, the cost height.
Use general ordinary bridge crane in the prior art, on lifting mechanism, connect by entablatrance, cross sill, gear motor constitute can rotating suspender.As Chinese patent application number is the three-in-one swing type mechanism that 200410060630.4 disclosed a kind of cranes for steelworks use are used, it comprises entablatrance, cross sill, parallel-axis type gear motor, sliding cross coupling, axis, it is characterized in that on entablatrance, connecting the parallel-axis type gear motor, the output hollow shaft of motor is connected with axis by sliding cross coupling, and axis connects cross sill.It though can alleviate the hoisting crane deadweight greatly, reduces the above factory building height of crane track face than above traditional crow crane, has reduced device fabrication difficulty and productive costs, makes workpiece revolution action become flexibly light and handy.But exist deficiency, mainly be to adopt ordinary bridge crane center lifting mechanism, its steel rope twines on a vertical plane surface, in processes such as rotary hanger rotation, trolley travelling, suspender and weight are easily swung, and amplitude of fluctuation is bigger, and the guidance quality that vertically hoists is bad, and then makes operational stability relatively poor.
Summary of the invention
The objective of the invention is to overcome above prior art design-calculated deficiency, design a kind of car load height of hoisting crane of both can realizing and reduce, reduce weight, reduce the upper limit of suspender, increase the space done of suspender, reduce construction costs etc.; Make crane hanger and weight have the vertical guidance quality that hoists again, can solve suspender vibration problems in the process of hoisting effectively, and the guiding and the rotating mechanism of the good crane hanger of operational stability.
Technical solution of the present invention is achieved in that the guiding and the rotating mechanism of crane hanger, comprises guiding mechanism, rotating mechanism and the hanger beam of suspender; Be characterized in: guiding mechanism is by the pulley gear be combined into of arranging on cruciform girder, steel rope and the trolley frame; On trolley frame, be provided with orthogonal pulley gear, be connected with four beam-ends of cruciform girder respectively around the steel rope that gets off, constitute a criss-cross, cruciform girder is located on level and vertical direction from lifting mechanism middle pulley device; Rotating mechanism is installed on the cruciform girder and is linked to each other with hanger beam.
Above-described rotating mechanism is made up of cruciform girder, three-in-one driving device, pivoting support and hanger beam; Three-in-one driving device be contained in cruciform girder above, pivoting support is loaded between cruciform girder and the hanger beam and is connected, the gear on the three-in-one driving device output shaft is meshed with the gear ring of pivoting support.
The rotation of crane hanger of the present invention and guiding mechanism and background technology relatively have the following advantages:
● adopt three-in-one driving device dress, pivoting support, realized the rotation of hanger beam.Make designs simplification, weight saving.
● reduce the limes superiors of suspender, increased the operational space of suspender.
● have the guidance quality that vertically hoists, solved suspender and the big problem of weight swing when lifting, guide frame is simplified greatly, operational stability is good.

The specific embodiment
Describe the guiding and the rotating mechanism of crane hanger of the present invention in detail below in conjunction with accompanying drawing.
Fig. 3 and shown in Figure 4, the guiding mechanism of crane hanger.Guiding mechanism is by pulley gear 4 be combined intos of arranging on cruciform girder 1 (perhaps being called entablatrance), steel rope 2 and the trolley frame 3.Be provided with four pairs of orthogonal pulley gears on trolley frame, that is to say pulley gear rectangular distribution on trolley frame, each angle of rectangle is provided with orthogonal two pulley gears.Be connected with four beam-ends of cruciform girder respectively around the steel rope that gets off from lifting mechanism 5 middle pulley devices, constitute a criss-cross.One end of steel rope is fixed on the reel, and the other end is fixed on the cruciform girder, and four direction adopts identical fixing means like this, and steel rope is located cruciform girder on level and vertical direction.
Fig. 5 and shown in Figure 6, the rotating mechanism of suspender.It comprises three-in-one driving device 8, pivoting support 6 and the hanger beam 7 that cruciform girder 1, two covers are made up by electrical motor, reductor, drg.Three-in-one driving device be contained in cruciform girder above, pivoting support is loaded between cruciform girder and the hanger beam.Gear 801 on the three-in-one driving device output shaft and 602 engagements of the gear ring of pivoting support are realized the spinning movement of hanger beam.Adopt the three-in-one driving device of two covers, both guaranteed the balance of mechanism, can overlap under the situation of driving device et out of order one again, but the another set of driving device short time works on.And pivoting support comprises rotary track 601, gear ring 602, ball 603, connector 604, tween drive shaft 605 and connects bearing pin 606; Rotary track by be bolted to rood beam below, gear ring is fixed on the top board 608 of connector by bolt 607, ball is loaded between rotary track and the gear ring, and in the mesopore of tween drive shaft plug-in mounting connector and rood beam, and the connector bottom joins with connecting bearing pin and hanger beam.
The guiding of crane hanger of the present invention and rotating mechanism have the claw device on the hanger beam, also can charged magnetic-disc etc.The present invention mainly is guiding and the rotating mechanism for metallurgical crow crane design-calculated suspender.Also can be applied on other hoisting crane.
