Description

Lifting structure for ladle cover

Technical Field

The utility model belongs to the technical field of steelmaking equipment, in particular to ladle be built by contract elevation structure.

Background

The traditional ladle turret is designed to control the ladle cover to lift by winding a steel wire rope, and because the service area of the ladle cover is high in temperature and high in dust and the like, the environment is severe, and the steel wire rope is broken, coiled disorderly and the like frequently, so that the safety operation of the ladle cover is adversely affected. The main problems of the traditional continuous casting steel wire rope hoisting ladle cover lifting system are as follows: due to the fact that the condition of the using area of the ladle cover is high in temperature, high in dust and the like, the environment is severe, and the steel wire rope is broken, coiled disorderly and the like frequently, and the safe operation of the ladle cover is adversely affected. Because the steel wire rope has the phenomena of stretching or knotting and the like, the precision of the lifting control of the steel ladle cover is not high, and an operator needs to continuously adjust the steel ladle cover to reach the required position. The weight of the ladle cover is 4-5 tons, and if the steel wire rope is broken, the ladle cover falls off, so that the safety of surrounding workers is greatly influenced. The steel wire rope hoisting system has high failure rate, great maintenance difficulty and great labor intensity of maintainers.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides a ladle cover lifting structure, which comprises a supporting frame, a lifting column and a ladle cover, wherein the supporting frame comprises a vertical column and a horizontal column which are fixedly connected with each other, the vertical column is vertically fixed on the ground, an electric lifting column is arranged below the horizontal column of the supporting frame, the electric lifting column comprises a sleeve which stands on the ground and a guide column which can vertically lift along the sleeve, the horizontal column which is vertically above the guide column is provided with a steering wheel, the horizontal column is provided with a steering wheel close to the lower part of the tail end, each steering wheel is positioned at equal horizontal height, each steering wheel is wound with a traction rope, one end of each traction rope is fixed with the top of the guide column, the other end of each traction rope is connected with a hook fixing block, the two traction ropes are respectively steered through the steering wheels and are parallel to each other, a hook is arranged below, the hanging ring is matched with the hook.

Further: the haulage rope is equipped with two strands, and the parallel is fixed between the free guide pillar top of lift post and couple.

Further: and scales are arranged on one side of the vertical column of the support frame, which faces the free guide column of the lifting column.

Further: the horizontal column of support frame is hollow sealed cylinder, and the horizontal column bottom of support frame is equipped with the round hole, run through in the round hole the haulage rope.

Further: and the edge of the round hole is provided with a soft ash blocking strip.

Further: the outer ring of the hanging ring is of a square structure, and the inner ring of the hanging ring is of an oval hollow structure.

Has the advantages that: the utility model discloses because the haulage rope seals the operation, consequently can overcome the relatively abominable environment such as the service area condition high temperature of ladle cover, high dust, safe operation can be realized in the lift of ladle cover. The lifting column is provided with scales, the precision of controlling the lifting of the steel ladle cover is high, the automation level of the equipment can be improved, and the personnel operation is simple. The double-wire operation, even one fracture, still have another haulage rope, be unlikely to take place the incident such as ladle cover drops, reduced staff's around the potential safety hazard. Simple structure, haulage rope are difficult for twining, do not need frequent maintenance, have reduced maintainer intensity of labour. The control accuracy is improved, the failure rate is reduced, the device can adapt to a severe working environment, and the safety and the working efficiency of the operating environment are improved.

Detailed Description

The present invention will be further clarified by the following description in conjunction with the accompanying drawings, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications of the various equivalent forms of the invention by those skilled in the art after reading the present invention are within the scope defined by the appended claims.

The utility model relates to a lifting structure of a ladle cover, as shown in figure 1, comprising a supporting frame, a lifting column and a ladle cover 8, wherein the supporting frame comprises a vertical column 1 and a horizontal column 2 which are fixedly connected with each other, the vertical column 1 is vertically fixed on the ground, an electric lifting column is arranged below the horizontal column 2 of the supporting frame, the electric lifting column comprises a sleeve 4 standing on the ground and a guide column 3 capable of vertically lifting along the sleeve 4, the horizontal column 2 above the guide column 3 is provided with 2 steering wheels 5, the horizontal column 2 is provided with 2 steering wheels 5 near the lower part of the tail end, each 2 steering wheels are positioned at equal level, each steering wheel 5 is wound with a traction rope 6, one end of the traction rope 6 is fixed with the top of the guide column 3, the other end is connected with a hook fixing block, two traction ropes 6 are respectively steered through 2 steering wheels 5 and are parallel with each other, a hook 7 is arranged below the hook fixing, the bag cover 8 is provided with a hanging ring 9, and the hanging ring 9 is matched with the hook 7.
