Description

[Detailed description of the invention] The invention relates to an improvement of a remote control shaft.
More specifically, at a construction site, etc., it is attached to the connecting end of a rope for suspending a load such as steel material transported by a crane, and suspends the load such as steel material, and after transportation, the rope can be freely controlled by remote control. This invention relates to a removable remote control shackle.

A conventionally used remote control shackle has a configuration disclosed in, for example, ``Kokoku No. 52-9755'', that is, as shown in FIG. At the same time, a shackle pin P, which is located in a protruding cylinder C provided on the opposite side and has a long index line r1 attached to one end thereof, is inserted or extracted in a parallel direction into the pin hole a by means such as pressing. A locking pin for fixing the fitted and locked state, that is, connects the index line r2 for operation to its upper end, and inserts the lower end into the fitting groove h of the shaft pin P to fit it. It has a configuration in which a locking pin b that can be fitted is provided upright on the opposite side of the pin hole a. Therefore, when using the shackle A, the shackle pin P is pressed and fitted into the pin hole a, and further, Insert the locking pin b into the fitting groove h of the fitted shaft pin P,
Shackle pin P must be fixed,
In addition, in order to pull back the shaft pin P, the same operation is performed in reverse, so at least two steps are required, which makes the operation complicated. Due to such resistance, it was difficult to pull it out in the horizontal direction smoothly.

Furthermore, as shown in the figure, since a protruding tube C is provided outside the shackle body A, when the crane is lowered after transporting the load, the shackle falls to the ground in an overturned state, and the index line r1, There is also a problem that makes it difficult to remotely control the r2, and a solution to this problem has been desired.

The present invention has been developed to eliminate these drawbacks of conventional products, and allows the support frame that supports the hanging ropes, etc. in the shaft to be locked or removed with a single touch, and can be controlled remotely. The purpose is to provide an improved remote control shackle that can be easily and quickly carried out, and its gist is that it is made up of two plates with a rod sandwiched between the lower ends and a space on the opposing inner surface. shackle bodies arranged opposite to each other, the upper part of which has a width that can be inserted into the space of the shackle body, and the lower end of which is pivotally connected to a support rod for forming a support means for supporting a hanging rope, etc.; A rotation support whose upper part is inserted between the upper parts of opposing plates forming a space in the shackle body so as to be pivotally connected to each other, and whose upper end extends into the inside of the shackle body to form a protrusion. a hook means located below the inner surface of the shackle body and removably connected to a support rod pivotally connected to the rotary support portion; and a hook means that is pivotally connected to the shackle body and the rotary support portion. a spring biasing means for pulling the upper end protrusion of the rotary support part toward the front end of the shaft body using a point as a rotation fulcrum; and a length having one end fixed to the hook in order to release the hook means as necessary. The remote control shackle is comprised of a hook operating section consisting of a length operating strip.

Hereinafter, the present invention will be explained in detail based on the accompanying drawings.

As shown in FIGS. 1 and 2, the remote control shaft according to the present invention is provided with a pivot shaft 12 as a suspension part on the head, and two high-strength steel sheets or the like at the bottom of the pivot shaft 12. A shell main body S is formed by bending plate bodies S1 and S2 between the inner surfaces to one side as shown in the figure with a space 2, and arranging them facing each other with a rod 1 sandwiched between the lower ends on the other side, and an upper part B1. The lower end has a width that can be inserted into the space of the shackle body S, and can be supported on the rod 1 of the shackle body S by restricting movement on the lower surface of the tip to form a support means for supporting a hanging rope or the like. A supporting rod 3 is pivotally attached to the recessed portion 3a, and the support rod 3 is provided with a cutout step portion 3b that is open toward the proximal upper side and can lock a hook means to be described later, on the upper surface of the distal end, and the upper portion is connected to the space of the shaft main body S. Insert into part 2 and insert the shaft body S.
An interior space N for the ends of the hanging ropes, etc. is formed between the other ends of the plates S1 and S2, and they are pivotally connected to each other directly under the pivot shaft 12, and the upper end is connected to the space of the shaft body S. a rotary support part B extending into the part 2 to form a protrusion 4; and a protrusion 5a on the lower surface of the tip located below the space part 2 of the shaft body S.
The hook 5b, whose base end is pivoted to one side between the plates S1 and S2, is elastically biased so that the protrusion 5a at the tip is directed downward. Hook means 5, which is provided with a biasing means to
and a spring biasing means 8 for pulling the upper end protrusion 4 of the rotation support part B toward the distal end of the shackle body S using the pivot point between the shackle body S and the rotation support part B as a rotation fulcrum. In order to release the hook means 5 as necessary, the hook 5b is provided with a hook operating portion consisting of a long operating strip 6 made of a rope or the like with one end fixed on the distal end side from the proximal end of the hook 5b.

Here, the rotation support part B is the upper part B as described above.
1 is formed to have a width that can be inserted into the space 2 of the shaft main body S, and at least the same width as the two plates S1 and S2 arranged facing each other from the center to the lower end, and the lower end is formed into an inverted U shape. It has a bifurcated shape, and a support rod 3 for forming a support means for supporting a hanging rope or the like is pivotally attached to the lower end.

Also, the upper surface and lower surface of the support rod 3 mentioned above,
As shown in FIG. 2, the explanation is based on the assumption that the support rod 3 is mounted and supported on the rod body 1.

If a tensile force is applied to such a long operating rod 6 by remote control, the protrusion 5a at the tip of the hook 5b will move upward, and the support rod 3 will move upward as shown by the dashed line in FIG.
is rotated outwardly together with the rotation support part B by the spring biasing means 8, and as the support rod 3 moves outward, the lock with the rod body 1 is released, so that the shaft The load W suspended from the support rod 3 can be automatically removed. During the tensioning operation, this elongated operating strip 6 passes between two spring-loaded collars 7, 7 which are pivoted at the upper part of the shaft body S, and exerts a relaxing effect on the collars 7, 7. This eliminates the sudden tension of the operating strip 6 caused by pulling, allowing smooth pulling operation.

Then, the protrusion 4 of the rotation support part B and the main body S
between the spring stop collar 9 which is elastically biased by a spring pin provided between the plates S1 and S2 in the lower part of the interior, that is, close to the interior space N between the shaft main body S and the rotation support part B; Projection 4 at the upper end of rotation support part B
A spring biasing means 8 for pulling the shaft toward the tip of the shackle body S is hooked, and the pivot point between the shackle body S and the rotation support part B is set to a rotation fulcrum P.
As such, the support rod 3 is used as a reference point for locking or releasing the hook means 5, and constitutes a shackle.

The spring retaining collar 9 is positioned not only to fix the spring biasing means 8 but also as a stopper for the hook 5b when the hook means 5 is released.

On the other hand, numeral 10 in the figure is a U-shaped member for hanging the shackle which is hung from the hook 11 of the crane via a rope or the like, as shown in FIG. Attach the bolt to the pivot shaft 12,
It is attached to the shaft via a nut.

Further, as shown in FIGS. 1 and 3, a pivot shaft 12a having a hole diameter into which a bolt or the like can be inserted is provided at the lower end of the plate S1 of the shaft body S.
By tightening the bolts appropriately, the suspended load W can be reduced.
It is also possible to make it possible to suspend the suspension ring portion 13 and the like at the tip of the support rope R together with the support rod 3.

Therefore, the above-mentioned remote control shaft according to the present invention has the following features as shown in FIG.
It is connected to the suspension member 10 via a suspension rope to the crane hook 11, and during actual work, the support rod 3 at the lower end of the rotation support part B that constitutes the shaft is in an open state, and the support rod 3 is connected to the suspension member 10 through a suspension rope. The end suspension ring part 13 of the rope for hanging the load W is inserted, and the support rod 3 is pushed from the outside of the support part B against the elasticity of the spring biasing means 8, so that the lower surface of the end of the support rod is inserted. 3a
is mounted on the rod 1 of the shackle body S, and the protrusion 5a of the hook means 5 in the shackle body S is locked to the notch step 3b at the upper end thereof, thereby raising the crane. to transport the load W to a predetermined position, and after transporting,
A worker located at a remote distance can use the long operating strip 6.
By pulling the hook means 5 of the shaft
At the same time, the support rod 3 is moved to the position shown by the imaginary line in the figure by the elasticity of the spring biasing means 8, and at the same time, the load W is released, and it is suspended again by a crane and ready for reuse. become what is done.

As described above, the remote control shackle according to the present invention includes a shackle body made up of two plates facing each other with a rod sandwiched between the lower ends and a space on the inner surface, and a shackle body with a space inside the shackle body. A plate having a cutout width wide enough to allow insertion, a support rod for forming a support means for supporting a hanging rope, etc. is pivotally attached to the lower end, and the upper part is arranged opposite to each other to form a space for the shaft body. Insert between the upper parts of the body,
A rotation support part which is pivotally connected to each other and whose upper end extends into the inside of the shackle body to form a protrusion, and a support rod which is located below the inner surface of the shackle body and is pivotally connected to the rotation support part. A spring-loaded spring is used to lock or release the support rod from the hook means, using a pivot point between the shaft body and the rotation support portion as a rotation fulcrum, the hook means being removably associated with the support rod. and a hook operating portion consisting of a long operating strip with one end fixed to the hook in order to release the hook means as necessary. Since the load suspension rope R, etc. can be attached to the shaft with a one-touch operation by simply pushing it into the main body S side, the attachment becomes extremely easy.

Further, after installation, the support rod 3 is locked by the hook means 5 in a state where it is always spring-biased by the rotary spring biasing means 8 hooked to the protrusion 4 of the rotary support part B. The engagement force becomes stable and strong.

After the load is transported to a predetermined position by a transport means such as a crane, a long operating rod 6 made of rope etc.
If the locking of the hook means 5 to the support rod 3 is released by remotely controlling the Since the support rod 3 can be moved downward with the minimum amount of movement required to release it, it can be released quickly and reliably without receiving any load from the suspended load W.

During this remote control, for example, if the long operating strip 6 is passed between two spring-loaded collars 7, 7 provided in the space 2 of the shell body S, the collars 7, 7 This acts to relieve the tension of the rope 6, making it easier to remotely control the shaft.

Furthermore, the remote control shaft according to the present invention pivots the shaft main body S and the rotation support part B in a well-balanced manner without forming a locally protruding end outward of the main body unlike conventional products, and has a long shaft. Since the shackle is configured with the base end of the operating strip 6 inside the shell body S, the long operating strip 6 inside the shell body S can be easily operated even if the shackle falls over after being transported by a crane. For example, even if the shell is transported underground, it can be operated remotely.

In addition, since the support rod 3, which is pivotally connected to the lower end of the rotation support part B whose upper part is pivotally connected to the shaft body S, is supported by being mounted on the rod body 1 in the space 2, the hook operation part When the hook means 5 is released from the support rod 3 by pulling, the support rod 3 is moved to the rod body 1.
It moves upward along the upper surface into the space 2 of the shaft body S, then moves downward along the upper surface of the rod, and then freely moves to the lower end of the rotating support B. It is supported while hanging down.

From this, when the support rod 3 is unlocked in order to remove the end of a hanging rope, etc. on which a load is suspended, from the support rod, the support rod 3 does not suddenly rotate downward, and the remote control shaft is nearby. Not only can injury to workers present in the area be prevented as much as possible, but the interior space N below the end of the hanging rope, etc. is completely open, making it extremely easy to remove or fall off the hanging rope, etc. It can be done.
