Abstract
The utility model discloses a dedicated hanger for hoisting a rolling-mill housing, which comprises a hanger body, wherein, the hanger body is in the shape of a flat cylinder; a hoisting platform is arranged at the lower part of the hanger body, and pin holes are formed at the upper part thereof; position blocks are fixedly connected to two surfaces at the lower part of the hanger body respectively; the position blocks are in threaded connection to a screw rod which is parallel to the axis direction of the hanger body; the upper end of the screw rod is in threaded connection with a pressure bar; a collar used for propping against the rolling mill to screw down the upper end surface of a screw hole is arranged at the lower part of the pressure bar; a pin roll is mounted inside the pin hole of the hanger body; steel bushings working as hoisting points are symmetrically sleeved on the pin roll on the two sides of the hanger body respectively; and partitioning plates used for clamping the steel bushings are arranged on the two sides of the steel bushings. The utility model can reduce or minimize the use of a hoisting cable, thereby reducing or eliminating the hoisting damage on the inner working surfaces of the rolling-mill housing, and ensuring that the rolling-mill housing is in a vertical state when being hoisted so as to be smoothly mounted on the base of the rolling-mill.
Description
Technical field
The utility model relates to a kind of special hanger for hoisting, relates in particular to a kind of large-sized rolling mills frame special hanger for hoisting.
Background technology
The main mode that large-sized rolling mills frame lifting is at present adopted is: one, cluster, and utilize the direct bind hider top of the trellis of steel rope to lift.When adopting this method to lift frame, restriction because of the lifting space, steel rope need back and forth twine at the top of frame, but the general weight of frame is bigger, the steel rope that adopts is thicker, makes this reality of work difficulty that operates bigger, and be easy to damage frame in-to-in finished surface in hoisting process, and steel rope also very easily is damaged, even produces unexpected; In addition, the method will guarantee that also there is sizable difficulty in frame by the squareness after slinging.Two, hanger formula, the method that the hanger that utilizes the frame both sides to be provided with directly lifts with steel rope.Adopt this hanging method, frame will set hanger when equipment making, and present large-scale frame generally is not provided with hanger.In addition, when using the steel rope lifting, also slightly the making work difficulty of this sling is increased greatly because of steel rope.Three, jig type, jig type suspender main body is a structure steel fabrication spare, because of the internal stress reason causes structural distortion easily, causes between jig and frame the gap big or local gap is too small in welding process; Thereby it is relatively loosening or relatively more difficult when toward frame on, installing after making jig be installed on the frame.And to eliminate its technology more complicated that adopts of distortion.
The utility model content
The purpose of this utility model provides a kind of large-sized rolling mills frame special hanger for hoisting that can reduce or avoid the use of steel rope as far as possible just in order to overcome above-mentioned deficiency of the prior art.
The utility model is achieved by following technical proposals: a kind of large-sized rolling mills frame special hanger for hoisting, comprise the suspender body, described suspender body is flat cylinder body shape, its underpart is provided with hoisting platform, top is provided with pin-and-hole, be connected with fixed block respectively on two planes of middle and lower part, described fixed block is threaded and the parallel screw rod of described suspender body axis direction, the upper end screw thread of described screw rod is connected with depression bar, is provided with the collar that is used to compress upper surface, mill screw hole below the described depression bar; In the pin-and-hole of described suspender body bearing pin is installed, is set with the steel bushing as suspension centre in the both sides of described suspender body respectively symmetrically on described bearing pin, the both sides of described steel bushing are provided with and are used for its dividing plate of clamping.
Described suspender body is the flattened cylindrical shape.
Be connected with fixed block respectively symmetrically on two planes of described suspender body middle and lower part.
The beneficial effects of the utility model are: suspension centre is arranged on the steel bushing that is installed on the bearing pin; can reduce or avoid as far as possible the use of steel rope; thereby reduce or eliminated the damage of lifting finished surface in the frame; the lifting of employing hoisting platform; guarantee to be in plumbness after frame is sling; so that can successfully be installed on the rolling mill base, improved the accuracy rate of suspender, optimized the lifting performance of suspender.Compared with prior art, there is following advantage in it:
1, the stability of lifting further improves.
2, safety is more reliable.
3, can reuse.
4, working accuracy height is more conducive to the protection to the frame finished surface.
5, not fragile can the preservation for a long time.
6, preceding assembling and the dismounting of lifting back are installed, the mechanization degree of utilization further improves.
7, be applicable to that frame top is provided with the frame in housing screw hole.
