Abstract

The invention relates to a plate hook, and in particular relates to a bidirectional plate hook which comprises a vertically arranged hook neck, wherein the lower end of the hook neck is fixedly connected or is integrally provided with an upper hook body; the bottom of the upper hook body is fixedly connected or is integrally provided with a lower hook body; and the upper hook body and the lower hook body are provided with indent cambered surfaces of which the indent surfaces face upwards and the opening directions in the horizontal direction are opposite to each other. By utilizing the plate hook, operation on steel ladles in two opposite directions is achieved.

Description

A kind of two-way plate hook

Technical field

The present invention relates to plate hook, particularly a kind of two-way plate hook.

Background technology

Plate hook is formed by steel plate amalgamation riveted joint, has high, pliable and tough good, the resistant to elevated temperatures advantage of intensity.Existing a kind of plate hook as shown in Figure 1, is formed by a plurality of hook sheet riveted joints, is single hook structure, and plate hook comprises hook neck 10 and the crooked coupler body 20 arranged of vertical setting, and the plate in plate hook 10 can not rupture simultaneously, and indivedual plates damage and can also change.Single hook is mainly used in the transportation of metallurgical ladle, because ladle has requirement to the opening direction of the coupler body 20 of plate hook, single the fixing of the opening direction of this list hook can only be carried out operation to the ladle of a direction, in the time need to operating the ladle of reverse setting, existing this list hook can't satisfy the demands, can only or change plate hook by rotary hanger and realize, operate very loaded down with trivial details.

Summary of the invention

The object of the present invention is to provide a kind of two-way plate hook, so that it carries out operation from both direction to ladle.

To achieve these goals, the present invention adopts following technical scheme: a kind of two-way plate hook, the hook neck that comprises vertical setting, the lower end of hook neck is connected or is integrally formed with upper hook body, the bottom of upper hook body is connected or is integrally formed with lower hook body, upper hook body and lower hook body have concave surface upward, inner concave arc surface that opening direction in the horizontal direction is contrary.

Described top of hanging neck is provided with lifting hole(eyelet), and the axis of described two inner concave arc surfaces and the axis of lifting hole(eyelet) are in same perpendicular.

Upper hook body comprises the upper transition linkage section be connected with hook neck lower end, and left, described upper transition linkage section is the updip swash plate from up to down be obliquely installed from left to right to the opening direction of described upper hook body.

Lower hook body comprises the lower transition linkage section be connected with the bottom of upper hook body, and to the right, described lower transition linkage section is the swash plate that has a down dip from up to down be obliquely installed from right to left to the opening direction of lower hook body.

The described swash plate that has a down dip comprises left seamed edge and right seamed edge, and the distance between left seamed edge and right seamed edge reduces from top to bottom gradually.

Beneficial effect of the present invention: owing to the present invention includes upper hook body and lower hook body, the inner concave arc surface of upper hook body and lower hook body opening direction in the horizontal direction is contrary, and the present invention can realize on two opposite senses the operation to ladle.

Further, the axis of two inner concave arc surfaces and the axis of lifting hole(eyelet) are in same perpendicular, compact conformation of the present invention, thereby the center of gravity that upper hook body or lower hook body bear gravity when the transportation ladle is positioned at above-mentioned perpendicular, avoided plate hook to deflect, improve the balance of plate hook, reduced the probability of this plate hook fracture.

Further, the distance between left seamed edge and right seamed edge reduces from top to bottom gradually, when the upper hook body load-bearing is excessive, can avoid the upper hook body fracture, has strengthened the intensity of the swash plate that has a down dip simultaneously.

The accompanying drawing explanation

Fig. 1 is the structural representation of existing a kind of plate hook;

Fig. 2 is the structural representation of the embodiment 1 of a kind of two-way plate hook of the present invention.

The specific embodiment

Embodiments of the invention 1, as shown in Figure 2: a kind of two-way plate hook, the hook neck 1 that comprises vertical setting, the lower end of hook neck 1 is integrally formed with upper hook body 21, the bottom of upper hook body 21 is integrally formed with lower hook body 22, upper hook body 21 and lower hook body 22 have concave surface upward, inner concave arc surface that opening direction in the horizontal direction is contrary, the top of hanging neck 1 is provided with the axis of the axis of 5, two inner concave arc surfaces of lifting hole(eyelet) and lifting hole(eyelet) 5 in same perpendicular.Upper hook body 21 comprises the upper transition linkage section 31 be connected with hook neck 1 lower end, lower hook body 22 comprises the lower transition linkage section 32 be connected with the bottom of upper hook body 21, left, upper transition linkage section 31 is the updip swash plate from up to down be obliquely installed from left to right to the opening direction of upper hook body 21.To the right, lower transition linkage section 32 is the swash plate that has a down dip from up to down be obliquely installed from right to left to the opening direction of lower hook body 22, and the swash plate that has a down dip comprises left seamed edge 321 and right seamed edge 322, and the distance between left seamed edge 321 and right seamed edge 322 reduces from top to bottom gradually.This two-way plate hook has a plurality of hook sheet riveted joints to form, and in order to make Load Balanced, is distributed on each hook sheet, and the side near inner concave arc surface on upper hook body 21 is provided with removable Upper gasket 41, and the side near inner concave arc surface on lower hook body 22 is provided with removable lower gasket 42.

In other embodiments of the invention, can also save Upper gasket and lower gasket.

In other embodiments of the invention, the distance had a down dip between left seamed edge and the right seamed edge of swash plate equates from top to bottom.

In other embodiments of the invention, the top of upper hook body is fixedly connected with the lower end of hook neck, and the bottom of upper hook body is fixedly connected with lower hook body.
