Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanger used when hoisting a through box for transporting parts and the like.

[0002]

[Prior Art]

 FIG. 5 shows an outline of an example of a through box used for transporting parts and the like. An outer plate b is attached to a frame a formed by a rectangular tube, along the upper edge of the frame a, and through the box. A part of the outer plate b is cut away to form a small window c at a position symmetrical with respect to the center of the box, and the upper edge of the frame a exposed at the small window c portion is used as a handle d. It is formed so that the hanging tool e is hooked on and lifted.

As shown in FIG. 6, a lifting tool e for lifting the above-mentioned box is slidably connected to a sling wire rope g having a suspending ring portion f at its upper end and a lower end portion of the sling wire rope g. And a hook h formed in an L shape so as to fit the handle d.

When hoisting the box, the hooks of a crane or the like are slung with four slings e of the hanging rope f of the wire rope g, and the hooks h of the four slings e are passed through the box. Inserted into each of the four small windows c provided in the box, hook the hooks h from the lower side of the handle d of the box, and use four sling wires to prevent the hooks from coming off the handle d of the box. The rope g is manually lifted and the hook of a crane or the like is slightly rolled up to loosen the sling wire rope g, and it is confirmed that the hook h of each lifting tool e is not disengaged from the handle d of the box. Operate a crane etc. to transport the box.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned hanging tool e, the hook h is easily disengaged from the handle d of the frame body a, and when the through box is transported by the four hanging tools e as described above, the four hooks h are separated from each handle d. There is a problem in that it is difficult for an operator to hold down the four hanging tools e by himself so that they will not come off.

In view of the above-mentioned situation, the present invention makes it difficult for the hook hooked on the handle to come off during slinging work, and moreover, after the transportation of the box is completed, the hook of the crane is simply unwound, and the hook is the handle of the box. The purpose is to provide a hanger that will automatically come off.

[0007]

[Means for Solving the Problems]

 The present invention is a lever having a lock device at the leading edge, a pin hole at the front end, and a cord attachment hole at the rear end that is offset with respect to the line connecting the lock device and the pin hole. And a hook having a pin hole at the upper end obtained by bending the neck into a dogleg shape and bending the body below the neck toward the upper end so as to form an L-shape. The lever and the hook are combined so as to face the offset side of the cord-shaped body mounting hole of the lever, and the pin is inserted into each of the pin holes to be rotatably connected.

[0008]

[Action]

 Therefore, according to the present invention, when the hook is hooked on the inside of the handle of the case and then the lever is set to be in an orthogonal posture with respect to the outer surface of the handle, the most advanced locking device of the lever is pressed against the outer surface of the handle. , Prevent the hook from coming off the handle.

When the cord connected to the rear end of the lever is slightly lifted, the lever rotates around the pin and tilts with respect to the outer surface of the handle, so that the locking device is released.

When the cord-like body is further lifted, the hook rotates around the handle, the horizontal portion of the L-shaped hook stops at the position where it abuts the lower surface of the handle, and the lever moves above the handle. It tilts in the direction in which the cord is stretched and stops. Moreover, since the center of the attachment hole of the cord and the center of the pin which are offset are lined up on the line extending in the direction in which the cord is stretched, the lock device is held in a state deviated from the upper surface of the handle.

Then, when the cord-like body is loosened after being conveyed through the box, the locking device of the lever is not effective as described above, and therefore the hook falls off by its own weight and comes off from the handle.

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing the outline of the hanging device of the present invention, FIG. 2 is a partially cut front view seen from the direction II-II of FIG. 1, and FIG. 3 (a) starts setting a hook on a handle. Fig. 3 (b) is a state diagram of the hanging device hooked on the handle, Fig. 3 (c) is a state diagram of the hanging device set on the handle, and Fig. 4 (a) is a sling Fig. 4 (b) is a state diagram of the hanging device in which the wire rope is started to be lifted, Fig. 4 (b) is a state diagram of the hanging device in which the hook rotates around the handle, and Fig. 4 (c) is a state of the hanging device in which the sling wire rope is stretched. It is a state diagram.

At the leading edge, a lock ball 3 having a ball 2 which is biased by a spring 1 and projects a part of a spherical surface is provided at a front end thereof with a pin hole 4, and at a rear end thereof with a pin hole 4. A lever 6 having a sling wire rope attachment hole 5 offset with respect to a line connecting the lock ball 3 and the pin hole 4 is provided.

The hook 10 attached to the lever 6 is formed by bending the upper portion of the main body 7 in a dogleg shape to form bosses 8 parallel to each other at a predetermined interval in the width direction of the main body 7, and A pin hole 9 penetrating in the width direction of the main body 7 is provided in the main body 7, and the lower part of the main body 7 is bent in the same direction as the upper part to form an L-shape. The length of the horizontal portion of the body 7 is set to be slightly longer than the diagonal dimension of the member forming the handle 13 (reference numeral d in FIGS. 5 and 6) of the box to be hung by the hook 10.

The tip of the lever 6 is placed between the bosses 8 of the hook 10 so that the tip of the hook 10 faces the offset side of the sling wire rope mounting hole 5 provided at the rear end of the lever 6. And then insert the pin 11 into the pin holes 4 and 9 by aligning the pin hole 4 provided at the tip of the lever 6 with the pin hole 9 provided in the boss 8 of the hook 10 to connect the lever 6 and the hook 10. Are rotatably connected about the pin 11. Reference numeral 12 is a sling wire rope connected to the lever 6 by passing one end through a sling wire rope mounting hole 5 provided at the rear end of the lever 6.

Next, the operation will be described. As shown in Fig. 3 (a), the tip of the hook 10 is inserted from the outside of the case into the small window of the handle 13 of the case, and the hook-shaped bent end of the main body 7 is shown in Fig. 3 (b). As shown in FIG. 3C, the hook 6 is hooked on the inside of the handle 13 so that it is in contact with the upper surface of the handle 13, and then the lever 6 is rotated so that the lock ball 3 is orthogonal to the outer surface of the handle 13. Set it to the posture.

When the lever 6 is set as described above, the ball 2 of the lock ball 3 provided at the most distal end of the lever 6 is biased by the spring 1 and pressed against the outer surface of the handle 13, so that the handle 13 is attached to the main body of the hook 10. It is sandwiched between 7 and the lock ball 3 of the lever 6.

Then, by operating a crane or the like (not shown) and lifting the sling wire rope 12 connected to the rear end of the lever 6 as shown in FIG. 4 (a), the lever 6 is centered on the pin 11. Since it rotates and tilts with respect to the outer surface of the handle 13, the lock ball 3 deviates from the outer surface of the handle 13.

When the sling wire rope 12 is further lifted, the hook 10 is pulled upward through the lever 6 and pivots around the handle 13 as shown in FIG. 4 (b) to form an L-shape. As shown in FIG. 4 (c), the horizontal portion of the main body 7 of the hook 10 stops at the position where it abuts the lower surface of the handle 13, and the lever 6 is tilted above the handle 13 in the direction in which the sling wire rope 12 is stretched. Stop. Then, the center of the sling wire rope mounting hole 5 and the center of the pin 11 which are offset are aligned on the line extending in the tensioning direction of the sling wire rope 12, so that the lock ball 3 deviates from the upper surface of the handle 13. Retained.

According to the above, the lock ball 3 is provided at the tip of the lever 6 connected to the upper end of the hook 10, and when the hook 10 is hung on the handle 13 of the box, the lock ball 3 of the lever 6 is held. The ball 2 of the lock ball 3 is biased by the spring 1 so that the ball 2 of the lock ball 3 is pressed against the outer surface of the handle 13 by setting the handle 13 of the lock box 3 so as to be orthogonal to the outer surface. Since it is sandwiched between the lock ball 3 of the lever 6 and the lock ball 3 of the lever 6, the hanging device is prevented from falling off during slinging, and when the box is lifted by the crane via the hanging device, the lever 6 is rotated. Since the lock ball 3 is formed so as to be inclined with respect to the outer surface of the handle 13 so that the lock ball 3 deviates from the outer surface of the handle 13, when the sling wire rope 12 is loosened after transportation through a box, the lock button 3 of the lever 6 is released. When the reel 3 does not work, the hook 10 falls off due to its own weight and comes off the handle 13.

It should be noted that the present invention is not limited to the above-described embodiment, and for example, a plunger may be used instead of the ball 2 of the lock ball 3, and the plunger may be biased by the spring 1. In addition, a chain or the like may be used instead of the sling wire rope 12 connected to the lever 6 of the hanging tool, and other various modifications can be made without departing from the scope of the present invention. ..
