Description

Furnace roof crane

Technical Field

The utility model relates to a hoisting equipment, specific theory has related to a furnace roof hoist.

Background

The furnace top crane is a hoisting device for hoisting and transporting blast furnace top equipment during blast furnace maintenance, and generally has a trolley structure. The height of the blast furnace roof is typically 50-100 m, and roof cranes are typically used in open, overhead and dusty environments. Because the lifting height is higher, the lifting hook group is influenced by the environment when the lifting hook group is in the upper limit position in no load, the lifting hook group shakes to possibly collide with other parts, the parts are likely to fall off, and potential safety hazards are formed; meanwhile, as the lifting height is higher, when the lifting hook group is lowered to the limit position, the steel wire rope can be wound; in addition, hoisting mechanism sets up completely on the trolley for the dolly dead weight is heavier, need fully consider its bearing capacity at design factory building top process, and steel construction material cost is higher.

In order to solve the above problems, people are always seeking an ideal technical solution.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-5, a furnace top crane comprises a trolley 1, wherein the trolley 1 comprises a frame, trolley travelling wheels and a hoisting fixed pulley block 7 which are arranged on the frame, and a travelling track which is arranged corresponding to the trolley travelling wheels, and a hoisting mechanism and a guide mechanism 3 are respectively arranged on two sides of the travelling track; and a steel wire rope of the hoisting mechanism is connected with the hoisting hook group 2 through the guide mechanism 3 and the hoisting re-positioning pulley block 7 in sequence.

Compared with the hoisting mechanism arranged on the trolley, the hoisting mechanism is arranged on the side part of the bridge, and the steel wire rope of the hoisting mechanism is connected with the hoisting hook group through the guide mechanism, so that the dead weight of the trolley can be effectively reduced, and the material cost of the trolley is reduced.

Further, the lifting hook group 2 comprises a lifting hook 10 mounting frame 9, a lifting hook 10 arranged at the lower end of the lifting hook 10 mounting frame 9, two groups of lifting pulleys 8 arranged at the upper end of the lifting hook 10 mounting frame 9, the lifting pulleys 8 are coaxially arranged and are arranged in two groups, a gap is reserved between the lifting pulleys 8, so that the steel wire ropes wound on the two groups of lifting pulleys are separated, and the steel wire ropes can be prevented from being wound to a certain extent.

Preferably, the lower part of the mounting frame 9 of the hook 10 is of a V-shaped structure.

Preferably, the side portion of the frame is provided with an anti-shaking device 6 corresponding to the lifting hook group 2, the anti-shaking device 6 comprises a telescopic mechanism 11 hinged to the side portion of the frame and a clamping portion 12 arranged at the telescopic end of the telescopic mechanism 11, and the frame is provided with a limiting portion corresponding to the hinged position of the telescopic mechanism 11 so as to limit the rotation angle of the telescopic mechanism 11.
