Abstract

<P>PROBLEM TO BE SOLVED: To provide a hoisting hook to be stably fitted to an object even if an eccentric load is applied and advantageous in strength. <P>SOLUTION: A rotary ring 2 to be rotated freely in 360 degrees in parallel with a fitting surface of an objective heavy material is provided, and two symmetric shafts are provided in coaxial positions in a direction at a right angle against a rotary shaft of the rotary ring, and rotary pin receivers 3A and 3B are fitted on these shafts. An insert pin 4 is inserted into a through-hole provided on one side of the rotary pin receiver. The rotary pin receiver connected by the insert pin can be freely rotated around the coaxial shaft with the rotary ring. These parts are fitted to the objective heavy part by fittings 1, and a stop bolt 5 having a withstand load is provided to prevent fall of the rotary ring. With this structure, the hoising hook has a function for rotating in two directions and can cope with the fitting surface and hoisting direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a hanging hook that is attached to and used on an object heavy object when a lifting tool such as a crane or a wire is used to perform lifting and hanging work.

Conventionally, most of them are used by simply screwing them into an object weight such as an eyebolt.
Some of them rotate in two directions, but they are unstable and disadvantageous in terms of strength because an eccentric load is applied in the direction of suspension.

Problems to be solved by the invention

Conventionally, there are the following drawbacks.
(B) In the case of eyebolts, the occupied volume of the ring portion protruding from the mounting surface is large, and there is a restriction that there is no other interference in the mounting location because of the integral shape.
(B) When a plurality of eyebolts are used, it is impossible to set the direction of each ring to an arbitrary direction because the ring portion and the screw portion are integrated, so long as the screwing amount is not adjusted.
If the screwing amount is adjusted, the guaranteed load cannot be secured.
(C) In the case of a conventional hanging hook that rotates in two directions, there is an eccentric load in either direction, so that an eccentric load is applied, and there is a problem in terms of strength and stability in the suspended state.
(D) Generally, two or more suspension hooks are often used by being attached, and the direction of the surface to which the hook is attached is not constant.
For this reason, a very dangerous state may occur depending on the mounting surface of the hanging hook and the hanging direction.

Hereinafter, means for solving the problems of the present invention will be described.

(F) FIG. 6 shows a three-view diagram of the mounting rotation operation state in the case of claim 1.
As shown in the figure, the rotating ring 1 (2) rotates 360 degrees in a direction parallel to the mounting surface. Further, the rotation pin receiver A (3A), the rotation pin receiver B (3B), and the insertion pin (4) can rotate about 200 degrees with respect to two concentric shafts of the rotation ring 1 (2). .
(G) FIG. 7 shows two views of the metal shell 2 (10).
It has a through hole for inserting a stepped bolt (12) in the center.
(H) FIG. 8 shows a two-sided view of the rotating ring 2 (11).
A wire rope (14) with a thimble is fitted to the two concentric shafts via a thimble receiving ring (13).
(L) FIG. 9 shows two views of the stepped bolt (12).
It is inserted into a through hole at the center position of the mounting bracket 2 (10), screwed into the target heavy object, and fixed, and has a function of preventing the rotation ring 2 (12) from coming off.
(Nu) FIG. 10 shows two views of the thimble receiving ring (13).
The rotating ring 2 (12) is fitted into two concentric shafts.
(L) FIG. 11 shows a perspective view of the wire rope with thimble (14).
A thimble is assembled at both ends of the wire rope, and is assembled into a thimble receiving ring (13) fitted into two concentric shafts of the rotating ring 2 (12).
(E) FIG. 12 shows a three-view diagram of the mounting rotation operation state in the case of claim 2.

FIG. 13 shows a state in which the object heavy object is suspended in the vertical direction.
FIG. 14 shows a state in which two objects are attached to the attachment surface of the object heavy object and suspended in the 45 degree direction.
FIG. 15 shows a state in which two are attached to both sides of the object heavy object and are suspended at one point on the center point.

The invention's effect

The effects of the present invention are as follows in both claims 1 and 2.
(A) Since it has a structure that can freely rotate in two directions, it can correspond freely to the mounting surface and the hanging direction.
(B) Since it can be rotated by concentric shafts in each of the two directions, an offset load is hardly applied, which is advantageous for ensuring safety.
(C) Even if there are other mounting protrusions in the azimuth that is a blind spot with respect to the hanging direction, it is not necessary to limit this.
(D) When the target heavy object is inverted while being suspended, even if the balance of the respective suspension direction and suspension force fluctuates, this can be handled without difficulty.
