Abstract
The utility model relates to mounting of a hot rolling mill, in particular to mounting equipment for a large-scale hot rolling and rough rolling mill. A lifting tool for lifting a frame of the large-scale hot rolling and rough rolling mill is characterized by comprising a pedestal, a shaft, a pair of pulleys and a group of lifting ring bolts, wherein the pedestal is shaped like a disc; a semi-cylindrical groove is formed in the lower surface of the pedestal in the diameter direction; two waist-shaped holes perpendicular to the groove are formed in two sides of the groove; the shaft is placed in the semi-cylindrical groove of the pedestal; supporting seats are arranged at the two ends of the shaft and fixed on the lower surface of the pedestal; the pulleys are used for mounting a steel wire rope in a sleeving manner, arranged on the shaft in a sleeving manner and are respectively arranged in one waist-shaped hole; and the lifting ring bolts are arranged on the top surface and the sides of the pedestal respectively. The lifting tool for lifting the frame of the large-scale hot rolling and rough rolling mill can be applied under the condition of narrow space in the height direction.
Description
Technical field
The utility model relates to hot-rolling mill to be installed, and relates in particular to large-scale hot rolling roughing mill erecting equipment.
Background technology
The major way that present large-scale roughing mill frame lifting is adopted is: one, cluster, and utilize the direct bind hider top of the trellis of steel rope to lift.When adopting this method hoisting frame, easily damage the finished surface of frame inside, and also very easily appearance damage of steel rope, safety is relatively poor; Two, hanger formula, the method that the hanger that utilizes the frame both sides to arrange directly lifts with steel rope.Adopt this hanging method, frame will set hanger adding man-hour, and two present heavy duty mill housings generally do not arrange hanger.Three, jig formula, jig formula suspender main body is structure steel fabrication spare, in welding process, because the internal stress reason easily causes structural distortion, cause between jig and frame excessive clearance or local gap too small, thus relatively more loosening or difficulty is installed after making jig be installed on the frame.
In addition, introduced a kind of large-scale roughing mill frame special hanger for hoisting in the utility model patent ZL 200820075867.3 large-sized rolling mills frame special hanger for hoisting, can overcome the shortcoming in the above hanging method commonly used, but, because this suspender top leans out to more than the frame top, use in the situation that lift very limited being difficult to of space.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of large-scale hot rolling roughing mill frame lifting appliance for hoisting is provided.The utility model uses in short transverse narrow space situation.
For addressing the above problem, a kind of large-scale hot rolling roughing mill frame lifting appliance for hoisting of the utility model, it comprises:
Base, it is disc, and the lower surface diametric(al) is provided with the semicolumn groove, and the groove both sides are provided with two waist shaped holes perpendicular to this groove;
Axle, it is placed in the semicolumn groove of base, and two ends are provided with the bracket that is fixed on base lower surface;
A pair of pulley for the cover steel rope, they are through on the axle, and are located at respectively in the described waist shaped hole,
One group of lifting eye bolt, they are separately positioned on base top surface and side.
Described large-scale hot rolling roughing mill frame lifting appliance for hoisting, it also comprises the outer ring that is enclosed within outside the base, is free-running fit between outer ring and the base, and described base lower surface outer rim is provided with the supporting plate of protuberate basic unit, and described outer ring is placed on the supporting plate.
The utility model chassis outer side face cooperates with screw box hole medial surface or outer ring medial surface; The outer ring is annular arrangement, is connected with base by supporting plate, and the outer ring is inboard to be cooperated with chassis outer side, the outside, outer ring and screw box hole are inboard to be cooperated, the effect of outer ring is to increase the suspender external diameter, and to adapt to the larger screw box hole of roughing mill R2, roughing mill R1 does not use during lifting; Axle cooperates with base groove, and steel wire loop passes from the base window on pulley, hang on the traveling crane gib head or the shoulder pole girder suspension centre on.Two lifting eye bolt are respectively applied to the suspender installation and removal.The utility model safety, stable high; The fitting surface working accuracy of suspender and frame is high, is conducive to the protection to the frame processing face; Suspender is built in frame inside fully, is more suitable for using in the short transverse narrow space situation; One cover suspender can be finished the lifting of two roughing mill frames of same project, highly versatile; Be particularly useful for the frame that the roughing mill frame top is provided with the screw box hole.
