Description

Technical Field

[0001] The utility model relates to the technical field of lifting slings, in particular to a hopper sling for charging a steel furnace. Background Art

[0002] As is known, charging cranes are indispensable handling equipment for the steelmaking process of modern steel enterprises, and have the characteristics of high working level, harsh working environment, complex handling combination movements, and high safety performance requirements. For a tipping hopper, there are generally three lifting points on both sides and one end, and the lifting points at the end are generally lifted and subjected to force only when the hopper is tipped, that is, only two lifting points are relied on for lifting. For some hoppers that do not need to be tipped, such as grab buckets for discharging materials at the lower end, four lifting points are usually set to improve stability. For example, the Chinese utility model patent with announcement number CN220723290U discloses a steel processing hopper, which is to fix the steel wire ropes of the four lifting points obliquely on a sling, and then lift them through a lifting mechanism, but there is still a risk of shaking and loss of lifting. If four steel wire ropes are to be lifted and controlled at the four lifting points individually, stably and easily, a special hopper sling needs to be designed. Utility Model Content

[0003] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a hopper hoist for charging a steel furnace. The hoisting structure design corresponding to four hoisting points is more reasonable and stable, which facilitates the steel wire rope to be hoisted more easily and stably through a fixed pulley.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A hopper hanger for charging a steel furnace comprises two parallel end beam frames and a cross beam frame fixed between the middle parts of the two end beam frames, a rotating frame is fixed at both ends of the end beam frames, the rotating frame comprises two spaced-apart and side-by-side frame plates, an upper rotating shaft and a lower rotating shaft are rotatably mounted between the upper and lower parts of the two frame plates along the length direction of the cross beam frame, the upper rotating shaft body is fitted with a movable pulley for winding a lifting wire rope, and the lower rotating shaft body is fixedly connected to a plate hook.

[0006] Furthermore, the crossbeam frame includes two side-by-side cross bars, and a plurality of longitudinal bars arranged along the length direction of the cross bars are connected between the two cross bars.

[0007] Furthermore, reinforcing angle plates are connected between the crossbars, the end beams and the longitudinal bars.

[0008] Furthermore, the surface of the frame plate is set to be a cross shape, and the end of the upper rotating shaft is rotatably installed corresponding to the cross center of the frame plate. A sealing plate is connected between the upper ends of the two frame plates and the outer ends away from the corresponding end beam frames.

[0009] Furthermore, a hinge seat is fixed in the middle of the upper surface of the end beam frame, and the hinge seat is hinged with balance arms at both ends for connecting the ends of the lifting wire rope through a hinge shaft.

[0010] Furthermore, a horizontal angle is formed between the hinge shaft of the hinge seat and the end beam frame.

[0011] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0012] The hopper hoist for charging a steel furnace disclosed by the utility model has an I-shaped layout of the entire hoist frame, which can ensure the structural strength while reducing the space occupied on both sides. At the same time, it can be distinguished from the traditional structure in which the movable pulley is installed on the upper surface of the frame, and the movable pulley is hidden in the protruding end of the end beam frame, and cooperates with the hinged hook below, so the lifting force is more reasonable and the structural layout design is simple. In summary, the utility model hoist is mainly used in lifting mechanisms with independent lifting control of the lifting points, and the corresponding four lifting points The lifting structure design is more reasonable and stable, which is convenient for the wire rope to pass through the fixed pulley for more relaxed and stable lifting.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction:

[0019] Combined with Figure 1-4The hopper sling for charging the steel furnace comprises two parallel end beam frames 5 and a cross beam frame 1 fixed between the middle parts of the two end beam frames 5. The two end beam frames 5 and the cross beam frame 1 form an I-shaped layout structure, thereby reducing the space occupied on both sides, so that the ends of the end beam frames 5 extend outward to prevent interference with hanging and lifting; as needed, the cross beam frame 1 comprises two side-by-side cross bars 101, and a plurality of longitudinal bars 102 arranged along the length direction of the cross bars 101 are connected between the two cross bars 101. In addition, the cross bars 101 and the end beam frames 5 and the longitudinal bars 102 are all connected with reinforcing angle plates 103, which greatly increases the structural strength of the entire sling frame;

[0020] A rotating frame 2 is fixed at both ends of the end beam frame 5. The rotating frame 2 includes two spaced-apart frame plates 201. An upper rotating shaft 6 and a lower rotating shaft 7 along the length direction of the cross beam frame 1 are rotatably installed between the upper and lower parts of the two frame plates 201. The two frame plates 201 can be welded to both sides of the end face of the end beam frame 5, or can be an integral structure with the two side walls of the end beam frame 5. According to needs, the plate surface of the frame plate 201 is set to a cross-shaped structure, the horizontal end is fixed to the end beam frame 5, and the end of the upper rotating shaft 6 is rotatably installed correspondingly to the end of the end beam frame 5. The cross center of the frame plate 201, the upper ends of the two frame plates 201, and the outer ends away from the corresponding end beam frames 5 are all connected with a closing plate 202, and the structural shape of the rotating frame is maintained by the upper rotating shaft 6, the lower rotating shaft 7 and the closing plate 202; the upper rotating shaft 6 is provided with a movable pulley 3 for winding the lifting wire rope, and the lower rotating shaft 7 is fixedly connected to the shaft body with a plate hook 4, and the movable pulley 3 is hidden in the protruding end of the end beam frame 5, and cooperates with the plate hook 4 hinged at the bottom, so that the lifting force is more reasonable and the structural layout design is simple.

[0021] As needed, a hinge seat 8 is fixed in the middle of the upper surface of the end beam frame 5. The hinge seat 8 is hinged with balance arms 9 at both ends for connecting the ends of the lifting wire rope through a hinge shaft. When the lifting points are controlled separately, the wire rope of each drum is wound around the corresponding movable pulley 3 for lifting. However, the deflection and shaking caused by the different lengths of the wire rope cannot be avoided. By connecting the end of the wound wire rope to the balance arm 9, the balance and stability effect can be increased. In addition, there is a horizontal angle between the hinge shaft of the hinge seat 8 and the end beam frame 5, which is convenient for the wire rope to be pulled crookedly and lifted, thereby improving the lifting stability.

[0022] Implement the hopper sling for charging the steel furnace described in the utility model, as shown in the attached Figure 4 As shown, it is only necessary to wind the drum wire rope of the lifting mechanism of the hoisting trolley around the corresponding movable pulleys 3, and then hook the four plate hooks 4 on the corresponding positions of the hopper. When the production space of the project is limited, the direction in which the hopper enters the factory is parallel to the furnace mouth, and the steel furnace is located outside the workshop, it will be more stable and safe to control the lifting of the hoist and move along the direction of the crossbeam frame 1.
