Abstract

The utility model relates to a hoist for a rake crane. It includes the upper beam, the spreader beam, the rake on the spreader beam, the material rake tilting mechanism, the three-in-one rotating drive device, and the spreader rotation mechanism installed between the upper beam and the spreader beam; its characteristics Yes: The rake tilting mechanism is installed on the spreader beam, and is composed of a motor, a reducer, a combined brake drive device, a connected drum, a steel wire rope on the drum, and a pulley on the spreader beam. The wire ropes on the drum are respectively connected with the corresponding rakes through pulleys. It has the advantages of simple structure, which can reduce the weight of the whole vehicle, reduce the upper limit of the spreader, increase the operating space, and have good synchronous control performance of the rake group. It can be used in crane equipment in rolling mills and warehouses of metallurgical enterprises.

Description

The crow crane suspender

Technical field

The utility model belongs to handling machinery, is specifically related to the crow crane suspender that a kind of smelter uses.

Background technology

The crow crane that uses in the smelter, the suspender of always having continued to use since fifties rotation, guiding mechanism form are top dolly, bottom dolly, guide frame and suspender.The 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.Tumbling and leading by the reel on the dolly of top and steel rope and guide frame realization suspender claw.This crane structure complexity, the dolly whole height is higher, and complete vehicle weight is big, the cost height.The operational space of suspender is less, the both sides claw tumble control synchronism relatively poor.

Summary of the invention

The purpose of this utility model is to overcome above prior art design-calculated deficiency, design a kind of integral structure that helps realizing improving hoisting crane, reduce the dolly height, and overall weight, and make the claw hanger structure simple, the crow crane suspender that the synchro control performance is good.

Technical solutions of the utility model are achieved in that a kind of crow crane suspender, comprise claw on entablatrance, hanger beam, the hanger beam, claw tipping mechanism, three-in-one device of rotation driving, and the suspender swing type mechanism that is installed with between entablatrance and hanger beam; Be characterized in: it is characterized in that: described claw tipping mechanism is loaded on the hanger beam, and make up actuating device, reach the bonded assembly reel by electrical motor, reductor, drg, the steel rope on the reel, the pulley of adorning on the hanger beam is formed; Steel rope on the reel links to each other with corresponding claw respectively through pulley.

The claw mechanism of the crow crane that the utility model provides and background technology relatively have the simple in structure of suspender, can reduce the weight and the cost-cutting of car load; Lower the limes superiors of suspender, increased the operational space of suspender, and advantage such as the synchro control performance of claw is good.

The specific embodiment

Fig. 1, Fig. 2 and shown in Figure 3, the crow crane suspender comprises claw 3 on criss cross entablatrance 1, hanger beam 2, the hanger beam, claw tipping mechanism, three-in-one device of rotation driving 4, and the suspender swing type mechanism 5 that is installed with between entablatrance and hanger beam; Claw tipping mechanism is loaded on the hanger beam, by electrical motor, reductor, drg combination actuating device 6, and the bonded assembly reel, the steel rope on the reel, the pulley of adorning on the hanger beam is formed.Steel rope on the reel (7) links to each other with corresponding claw respectively through pulley (8).Drive the suspender swing type mechanism by the three-in-one device of rotation driving of two covers.

Reel is provided with two steel ropes 7, and the pulley 8 of steel cable through being contained in hanger beam web one side links to each other with a claw; Another root steel rope turns to for twice through deflection sheave 9, by being contained in the pulley 8 of hanger beam web opposite side, is connected on another claw.

Above-described claw 3 is per two one group, is connected as one by connecting rod 301.With an axle 302 two groups of claws are installed on the hanger beam.

The crow crane suspender that the utility model provides can be used in the crane facility in procedure for steel rolling in metallurgical industry workshop and warehouse.
