Description

Wire holding device for cranes {Wire holding device for crane}

The present invention relates to a wire holding device for a crane, and more particularly, to a wire holding device for a crane for the operator to hold the wire of the crane for lifting heavy loads in steelworks and the like to adjust the direction or position.

In general, the work to move or load a large load of articles such as coil (C), beams, steel pipes, etc. are frequently performed in steel mills. Therefore, the crane for such a job is easy to lift the goods, but sometimes the lifting goods rotates, and because it is difficult to adjust the direction to move properly, it is difficult to work smoothly and lifted the goods by the crane. The location of the wire often deviates from the center of the article, resulting in a high risk of catastrophic accident.

Moreover, previous workers wanted to eliminate the risk by pushing or pulling the item directly without any tools to adjust the position of the item and by pulling the off-centered wire to center it, but rather it was a very dangerous danger that seriously threatened the safety of the worker. It's a task.

Therefore, a tool for enabling the work even a little apart from the article, and the operator to adjust the center of the wire even during transportation of the article, that is, the wire holding device (1) as shown in Figure 1 has been developed and used , This is to have a configuration that pulls or pushes the wire (A) by using the pull hole 11 or the pusher 12 of the state in which one side is open so that when the operator pushes or pulls the wire for the direction guidance of the article By holding or rotating the holding device 1 is also a disadvantage that is also a serious threat to the safety of workers.

In addition, the conventional wire holding device (1) is a type of fixed size of the pull hole 11 or the pusher 12 has a disadvantage that is unreasonable to apply to all the wire for the crane having a variety of thickness.

Therefore, the present invention has been devised to solve the disadvantages of the conventional wire holding device, so that it can be held in consideration of this regardless of the diameter size of the wire, and while the worker is holding the wire holding device of the present invention It is to provide a wire holding device for a crane configured to be separated from the wire holding device.

Referring to the configuration of the subject innovation in detail as follows.

1 is an exploded perspective view for showing the configuration of the present invention, the wire holding device 1000 for the present invention is a length extension rod (1100) having a built-in towing wire (1120) and the length extension The forceps part 1200 is formed at the tip of the rod 1100 and the forceps driving part 1300 is formed at the other end of the length extension rod 1100.

The tongs unit 1200 is a substrate 1210 having a coupling portion 1211 is fitted to be coupled to the front end of the length extension rod 1100, and through the through hole 1212 of the substrate to enable reciprocating movement A towing 1220 coupled to the pinion gear 1221, a pair of rack gears 1230 to be fitted to both sides of the pinion gear 1221, and fixed to the rack gears 1230. A tongs 1240 having a curved shape coupled to be interlocked, an axial bolt 1214 for coupling the gears and tongs to a substrate, a cover 1213 and a bolt 1215 to cover the substrate. )

An end of the tow 1220 is connected to the towing wire 1120 by a connector 1121, and the tow wire 1120 is connected to the tightening lever 1320 of the tongs driving unit 1300. Since the tightening lever 1320 acts as a lever by the shaft 1310, when the operator grips the tightening lever 1320, the towing wire 1120 is pulled, and the towing hole connected to the towing wire 1120. The pinion gear 1221 of 1220 is pulled to induce rotation of the rack gear 1230 and eventually tongs 1240 fixed to the rack gear 1230 rotate about the shaft bolt 1214. Will be tightened inward.

At this time, the tongs 1240 are configured to overlap each other alternately, and also because the shape of the tongs 1240 has a curved arc shape, the diameter is narrowed as it is tightened inward, so that the wires (A, B) Regardless of diameter, holding without gap is possible.

In addition, the present invention forms a toothed portion 1410 in the traction wire 1120, as shown in Figure 6, the toothed portion 1410 is to be fixed by a wire fixing member 1420, wherein the wire fixing The structure of the member 1420 is as follows.

That is, the wire fixing member 1420 is rotatable by the shaft 1421 formed in the middle portion, the pressing hole (1423) is formed on one side so as to be exposed out of the length extension rod (1100) and the tooth portion (1410) on the other side A locking step 1422 to be engaged is formed.

The catching jaw 1422 has elasticity by an elastic member 1424 such as a rubber bar or a rubber ring, a spring, and is always provided to the toothed portion 1410 before pressing the pusher 1423. Will remain engaged.

At this time, the inclined direction of the tooth portion 1410 is formed to be inclined toward the forceps driving portion, so that it is preferable to configure the hooking jaw 1422 only when the operator pulls and releases the traction wire 1120.

As such, the present invention enables a perfect holding (regardless of the diameter size of the crane wire), and the tongs have a curved shape so that when the wire is picked up, the open part is not formed so that the worker has the present invention. While holding the wire will have the effect of preventing the wire from being separated from the wire holding device.

In addition, the present invention is to have a structure that can be fixed to the forceps so that the wire once held is a very useful design that can easily maintain the operator's work to maintain the state of holding the forceps.
