Description

Double line connecting apparatus for crane

The present invention relates to a two wire connecting device for a crane.

A crane refers to a machine that lifts a large load carrying object and moves it in the vertical direction or the horizontal direction.

In order for such a crane to lift the carrying object, a hook is fastened to a wire end extending from the arm end portion of the crane, and the carrying object is caught by the hook.

On the other hand, if it is necessary to move the carrying object of various loads, according to the load of the carrying object, the wire should be connected to the crane by either a single line or a double line, and the hook should be connected to the wire. .

A wire connecting ring is fastened to an end of the wire. When the wire is connected in a single wire shape, the wire connecting ring is directly fastened to a hook, and thus, the crane and the hook may be connected to the wire in a single wire shape.

On the other hand, when the wire is connected in a two-wire form, the wire connecting ring is fastened to a portion of the crane, the wire extending from the crane is fastened to another part of the crane, the wire is connected to the crane in a two-line form It becomes possible.

However, in the related art, when a wire is connected to a crane in a double wire form, the hook applied in the case of a single wire form cannot be fastened to a wire of a double wire form, thus excluding a hook applied in the case of a single wire form, A separate hook, which was larger and could be connected to the two wires, had to be connected to the two wires. Accordingly, the hook applied in the case of the single wire form and the hook applied in the case of the double wire form must be provided together, and both hooks must be fastened alternately according to the load of the carrying object, resulting in inconvenience, The increase can reduce the working efficiency.

In addition, the hook applied in the case of the two-wire form is a form that must be wound around the wire a plurality of times, so as to separate the wire connecting ring fastened to the end of the wire, wound the wire to the hook a plurality of times, and then the wire connecting ring Since it is necessary to fasten to the end, inconvenience is caused, and the working efficiency may be reduced due to the increase of working time.

An object of the present invention is to provide a two-wire connection device for a crane that can be easily fastened to the wire even in the case of a two-wire hook applied in the case of a single wire form.

Two-line connection device for a crane according to an aspect of the present invention is a base panel; A cover panel spaced apart from the base panel and connected to the base panel; A pulley rotatably connected between the base panel and the cover panel; And a hook connecting ring fastening part formed on at least one of the base panel and the cover panel, and the hook connecting ring connected to the hook can be fastened.

It is applied to the crane including a wire extending from the arm of the crane and a wire connecting ring which is fastened to the distal end of the wire and directly connected to the hook when connected in the form of a single line,

With the wire connecting ring connected to the wire, the wire connecting ring penetrates between the base panel and the cover panel so that the wire is caught by the pulley, and the wire connecting ring is connected to another part of the arm. Connected to the wire connected to the arm in the form of a double line,

The hook connecting ring is fastened to the hook connecting ring fastening part, so that the hook is connected to the wire connected to the arm in the form of a two wire.

According to the two-wire connection device for a crane according to an aspect of the present invention, the two-wire connection device for a crane includes a base panel; A cover panel spaced apart from the base panel and connected to the base panel; A pulley rotatably connected between the base panel and the cover panel; And a hook connecting ring fastening part formed on at least one of the base panel and the cover panel to fasten the hook connecting ring connected to the hook, thereby connecting the wire to the crane in the form of a wire. It is possible to fasten the hook applied to the wire in the form of two wires as it is, it is not necessary to have a separate hook for the two-wire form, the work due to the inconvenience and increased working time due to such a separate hook and hook replacement It is possible to eliminate the deterioration of efficiency, and to connect the hook to the wire in the form of a wire without disconnecting the wire coupling fastened to the end of the wire. There is an effect that can solve the degradation of the work efficiency due to the increase of time.
