Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a hoisting machine that is convenient for loading and unloading a block, etc. It was made possible.

(Prior Art and Problems Thereof) Conventionally, when transporting a knowledge block, one or two pieces are suspended by a gripper and loaded or unloaded on a bed of an automobile.

However, this method is inconvenient because it takes too much time to load and unload. As a means for solving this inconvenience, the applicant first applied the principle of the telescopic arm so that a plurality of intelligent blocks etc. can be simultaneously hung up and down by a single operation of the suspension machine and transported. We devised a device that can be hung securely with quick work (Japanese Patent Application No. 25995/1990).
No.), it is not efficient because the interval width of the sandwiching rods must be widened manually for each loading and unloading work.

(Means for solving the problem) The present invention has been devised to eliminate such inconvenience of the conventional means, and automatically expands and lowers the operation of widening and reducing the holding rod in the suspension machine for each work. It aims to save labor and measure the speed and certainty of work.

The present invention will be described in detail with reference to the illustrated embodiment.
And a lock mechanism 2, and the suspender 1 comprises a pair of suspender main bodies 3 and 3 and a suspending rod 4 and sandwiching rods 5 and 5 which are installed between the suspender main bodies 3 and 3. In the suspender main bodies 3 and 3, the fixed plate 6 and the bent portions 11 and 1 are arranged so that the clamping claws 7 and 8 face the fixed plate 6 and the handle portions 9 and 10 intersect each other.
It is composed of bending rods 13 and 14 supporting 2 and a folding rod 15 pivotally attached to the tips of the handle portions 9 and 10, and the hanging rod 4 is a folding rod of the folding machine main bodies 3 and 3. It is rotatably installed between the tatami portions 16, and the holding rods 5, 5 are installed on the corresponding holding pawls 7, 8.

The lock mechanism 2 includes the fixing plates 6 and 6 of the suspender main bodies 3 and 3.
The hanging portion 18 provided on the pedestal 17 installed on the
A lock plate 19 mounted so as to be freely rotatable and tiltable to the left and right, and a suspending and falling plate 20 provided on the upper part of the hanging rod 4 and provided with a weight 28 on one surface side so as to be able to fall only on the one surface side. The latching portion 18 is composed of a latching projection 22 provided on a pedestal 21 fixed to the pedestal 17, and a dissociation plate 24 rotatably supported in the direction of the projection 22 and provided with an operating rod 23 on the upper portion thereof. The lock plate 19 is provided with a guide part 25 at the lower end and a hook groove 26 provided in the middle of the side part, and a suspending rod 27 is provided on the suspending falling plate 20 so as to operate when the suspending falling plate 20 falls down. The rod 23 can be pushed down freely.

The suspending board 20 has a suspending hole 29 formed therein so that a hook 30 of a crane or the like can be hooked.

(Operation) The present invention is embodied as described above. To explain this operation, first, the knowledge block 31 is arranged in a factory or the like, and the lock plate 19 is placed on the engaging portion 32 of the knowledge block 31. When the hooking portion 18 is hooked on the hooking protrusion 22, that is, in the state shown in FIG. 2 (FIG. 4 (a)), the holding rod 5 is moved.
Lower 5 It is further lowered by its own weight. That is, the folding rod 15 is rotated outward, and the sandwiching claws 7 and 8 are rotated outward, and when the folding rod 15, the bending rods 13 and 14 and the like are sufficiently lowered, the hanging and falling plate 20 is suspended. 28, and the lodging rod 27 pushes down the operating rod 23. The operating rod 23 rotates the dissociation plate 24 to tilt the lock plate 19 (first
Disengage the lock groove 26 of the lock plate 19 and the lock projection 22 from each other (dotted line in the figure). The unlocked lock plate 19 rotates while being pushed by the dissociation plate 24 and descends in the state shown in FIG.

After confirming that the sandwiching rods 5 and 5 have sufficiently abutted against the engaging portion 32 of the block 26, the hook 30 of the crane is pulled up, so that the suspending and falling board 20 is inverted, and the falling board 27 and the operating rod 23. When the lock plate 19 is released, the lock plate 19 is released by the rotation of the dissociation plate 24, the lock plate 19 is tilted in the vertical direction, and the lock plate 19 hangs down, so that the locking projection 22 abuts the side surface of the lock plate 19 and Latching protrusion 22
It is pulled up in a free state (Fig. 4 (c)) without engaging with. Thus, the clamping rods 5 and 5 are reliably clamped and moved by the knowledge block 31.

The intelligent block moved to a predetermined position is unloaded in the following order. That is, the folding rod 15 bends downward, the sandwiching claws 7 and 8 expand, the sandwiching rods 5 and 5 are released from the block block 31, and the guide portion 25 of the lock plate 19 and the latching protrusion 22 slide. (FIG. 4 (d)), the hook groove 26 and the hooking projection 22 are engaged (FIG. 4 (e) (f)), and the state is shown in FIG. 2 (FIG. 4 (a)). become. Repeat in the following order.

(Effect) As described above, in the hanging machine 1 including the hanging machine 1 and the lock mechanism 2, the lock mechanism 2 is mounted on the fixed plates 6 and 6 of the hanging machine main bodies 3 and 17 so that the lock 17 can be installed. And a lock plate 19 attached to the hanging rod 4 so as to be rotatable and tiltable right and left, and the hanging rod 4.
It is provided with a weight 28 on the one surface side provided on the upper part of the above, and a suspending and falling plate 20 which can be laid down only on the one surface side.
Is a hooking protrusion 22 provided on a pedestal 21 fixed to the pedestal 17,
The lock plate 19 includes a disengagement plate 24 which is rotatably supported in the direction of the projection 22 and has an operating rod 23 provided on the upper portion thereof. The lock plate 19 has a guide portion 25 at the lower end and a hook groove 26 provided in the middle. Since the hook groove and the hooking projection 22 can be engaged with each other, and the suspending board 20 is provided with a projecting rod 27 so as to be able to push down the operating rod 23 when the suspending board 20 falls down, the suspending machine Narrowing rod 5, only by pulling down and pulling up
In No. 5, it is possible to repeat the movement onto the target object, the pinching of the target object, and the release of the target object in the state of being spread, and it is possible to save labor and improve work efficiency.
