Abstract
The invention discloses an annular internal expanding type steel coil lifting appliance which belongs to the technical field of a lifting appliance. The annular internal expanding type steel coil lifting appliance comprises a conical slide hanging pillar and an annular supporting body which sleeves the slide hanging pillar, wherein the inner surface of the supporting body is in a conical shape matched with the shape of the slide hanging pillar; the supporting body is uniformly divided into at least two supporting units along the circumferential direction, the inner surface of each supporting unit is provided with a slide rail, and the slide hanging pillar is connected with the supporting body in a sliding manner through the slide rail; the slide hanging pillar comprises a small end and a big end, and a hanging ring stretching out of the supporting body is fixed on the small end. Friction is produced between the outer circumferential surface of the supporting body and the inner surface of a steel coil, so that good stress and friction strength can be guaranteed, the supporting force is large and firm, and the steel coil is prevented from being scratched.
Description
Technical field
The present invention relates to suspender technical field, in particular to a kind of annulus internal-expansion type coil grab.
Background technology
The suspender of steel coil handling is generally supported by the external diameter of coil of strip or inside diameter surface to sling, if utilize the external diameter surface of coil of strip, because its external diameter of coil of strip of different size is also different, a suspender is difficult to well meet different coil of strips simultaneously; Some suspenders utilize the internal diameter of coil of strip, utilize friction force to be sling by coil of strip by articulated bracket by interior swollen mode, but the inside diameter surface of suspender and coil of strip is linear contact lay, stressed shakiness, frictional strength is low, and bearing force is little, interior built on the sand swollen, and easily cause coil of strip to scratch.
Summary of the invention
The object of the present invention is to provide a kind of annulus internal-expansion type coil grab, to solve the problem.
For realizing the object of the invention, the technical scheme of employing is: a kind of annulus internal-expansion type coil grab, comprises cone shape slip davit and is enclosed within circular supporter outside slip davit, the inside face of supporter in slip davit match coniform; Supporter is circumferentially evenly divided at least two pieces of support units, and the inside face of every block support unit is provided with slide rail, and slip davit is by slide rail and supporter sliding block joint; Slip davit comprises small end and large end, and small end is fixed with the suspension ring stretching out supporter.
Further, described supporter is circumferentially evenly divided into four pieces of support units.
The invention has the beneficial effects as follows, the circular supporter being divided into polylith is slided by the upwards lifting of slip davit, it is made to open to radial direction, thus the interior swollen inside face being supported on coil of strip, and be that the outer circumference surface of supporter and the inside face of coil of strip produce friction force, be face contact, ensure good stressed and frictional strength, bearing force is large and firm, and coil of strip can not be become to scratch.
Accompanying drawing explanation
Fig. 1 is the cutaway view of annulus internal-expansion type coil grab provided by the invention;
Birds-eye view when Fig. 2 is swollen use in annulus internal-expansion type coil grab provided by the invention.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show annulus internal-expansion type coil grab provided by the invention, the circular supporter 1 comprising cone shape slip davit 2 and be enclosed within outside slip davit 2, the inside face of supporter 1 in slip davit 2 match coniform; Supporter 1 is circumferentially evenly divided into four pieces of support units, and the inside face of every block support unit is provided with slide rail 3, and slip davit 2 is by slide rail 3 and supporter 1 sliding block joint; Slip davit 2 comprises small end and large end, and small end is fixed with the suspension ring 4 stretching out supporter 1.Supporter 1 can be divided into the support unit of respective numbers according to specific needs.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
