Description

Lifting appliance for solid winding drum

Technical Field

The utility model relates to an auxiliary device for steel strip production, in particular to a lifting appliance for a solid winding drum for lifting the solid winding drum of a multi-roller mill.

Background

At present, steel wire ropes with noses at two ends are adopted in a steel pipe processing workshop to hoist solid drums of a multi-roll mill. The hoisting process is that the upper ends of two steel wire ropes are connected with a hook of a travelling crane; then the lower ends of the two steel wire ropes are sleeved on the two ends of the solid winding drum; and finally, starting the travelling crane for hoisting. When the steel wire rope is used for hoisting, the steel wire rope needs to be sleeved on the solid winding drum from one end of the solid winding drum, and the operation is inconvenient in a narrow space. And, during wire rope handling, be an isosceles triangle between two wire rope and the reel, the contained angle between wire rope and the solid reel is the acute angle promptly, and when the solid reel had the steel band coil, wire rope can lead to the fact the damage and scrap some steel band with the outer lane edge contact of steel band coil.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a lifting appliance for a solid winding drum, which is convenient to lift the solid winding drum by adopting a high lifting appliance and cannot damage a steel belt.

In order to solve the problems, the following technical scheme is provided:

the lifting appliance for the solid winding drum is characterized by comprising a supporting drum which is horizontally arranged, hooks which are vertically and downwardly arranged are fixed at two ends of the supporting drum, the hook doors of the two hooks face in the same direction, and the hook doors of the two hooks are perpendicular to the axis of the supporting drum. The top of the supporting cylinder is fixedly provided with a connecting plate which is vertically and upwards arranged, and the middle part of the connecting plate is provided with a hanging hole.

The upper end of the hook handle of the hook is integrally connected with a lantern ring, the lantern ring is sleeved at the end part of the supporting cylinder, and the lantern ring is fixedly welded between the supporting cylinders.

The both sides of lantern ring and couple all are planar, and the side of lantern ring and couple all is perpendicular with the axis of a support section of thick bamboo.

Two perpendicular limits of connecting plate offset with two lantern rings respectively, and be welded fastening between perpendicular limit of connecting plate and the lantern ring that corresponds.

The hanging holes are waist-shaped holes which are vertically arranged.

By adopting the scheme, the method has the following advantages:

because the hooks which are vertically and downwardly arranged are fixed at the two ends of the supporting cylinder of the lifting appliance for the solid winding drum, the hook doors of the two hooks face in the same direction, the hook doors of the two hooks are perpendicular to the axis of the supporting cylinder, the top of the supporting cylinder is fixed with the connecting plate which is vertically and upwardly arranged, and the middle of the connecting plate is provided with the hanging hole. When the hanger is used, the whole hanger is connected with a hook of a travelling crane through the hanging hole. During hoisting, the crane drives the hoisting tool to descend firstly, so that the two hooks descend below the solid winding drum; then, hooking two hooks at two ends of the solid winding drum from the lower part of the solid winding drum; and finally, starting the travelling crane for hoisting. Such a hanger fixes the solid reel from below the solid reel and is operable in a narrow space. And the hook is vertically arranged and cannot be in contact with the steel belt on the solid winding drum, so that the steel belt cannot be crushed, and the problem that the steel pipe is partially scrapped due to extrusion is avoided.

fig. 2 is a schematic perspective view of a spreader for a solid reel according to the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the solid drum lifting appliance comprises a horizontally arranged support drum 1, hooks 5 which are vertically and downwardly arranged are fixed at two ends of the support drum 1, hook gates of the two hooks 5 face in the same direction, and hook gates of the two hooks 5 are perpendicular to the axis of the support drum 1. The top of the supporting cylinder 1 is fixed with a connecting plate 2 which is vertically and upwards arranged, and the middle part of the connecting plate 2 is provided with a hanging hole 3. The upper end of the hook handle of the hook 5 is integrally connected with a lantern ring 4, the lantern ring 4 is sleeved at the end part of the supporting cylinder 1, and the lantern ring 4 is fixedly welded between the supporting cylinders 1. The two sides of the lantern ring 4 and the hook 5 are both planar, and the side surfaces of the lantern ring 4 and the hook 5 are both vertical to the axis of the support cylinder 1. Two perpendicular limits of connecting plate 2 offset with two lantern rings 4 respectively, and 2 perpendicular limits of connecting plate and the lantern ring 4 that corresponds are welded fastening between.

In order to be connected with a travelling crane conveniently, the hanging holes 3 are waist-shaped holes which are vertically arranged.

When in use, the whole lifting appliance is connected with the hook 5 of the travelling crane through the hanging hole 3. During hoisting, the crane drives the hoisting tool to descend firstly, so that the two hooks 5 descend below the solid winding drum. Then, two hooks 5 are hooked on both ends of the solid roll from below the solid roll. And finally, starting the travelling crane for hoisting.

The whole hanger for the solid winding drum is CJ-shaped, the hooks 5 on two sides are cut by A3 steel plates, the thickness is 30mm calculated according to 15 tons of hangers, the length is estimated to be about 1.2 m according to the maximum diameter 2 m of a steel strip of the solid winding drum, the supporting drum 1 is a steel pipe with the inner diameter of 100mm, the wall thickness is 20mm, the length is controlled to be 0.9 m and is close to the width of the middle part of a hull of a rolling mill, the connecting plate 2 is also an A3 steel plate with the thickness of 30mm, and the connecting part of the connecting plate 2 and the supporting drum 1 is integrally welded to increase the integral strength of the hanger.
