Description

  TECHNICAL FIELD The present invention relates to a method and a jig for safely performing a slinging operation by adjusting a contact state between a suspended wire and a suspended load when lifting the various suspended loads such as a roll by hanging the wire. It is.

  For example, in roll manufacturing plants, roll materials and roll products are manufactured consistently in the factory. At that time, the movement of the roll is suspended and transported via a wire suspended on a crane hook. . In the case of a roll, use two wires to hang around the roll while considering the balance, hook the tip of each wire on the hook of the crane, move it to the work place, and lower the hook. It is mounted on a mounting table and performs roll processing.

  However, when the roll is placed on the placing table, the wire is in a loose state, and the wire tends to move below the hook at the center in the roll width direction due to twisting of the wire or the like. Therefore, when the processing of the roll is completed and moved to the next process, it is necessary to return the wire to the original position and balance it as in the first hanging work, which is troublesome and troublesome. there were. In addition, in order to return the wire to the original position, the hook is lowered to loosen the tension between the roll and the wire, and the operator pinches the hand between the wire and the roll to return the wire to the original position by hand. There was a risk of occurring.

  In order to solve this problem, Patent Document 1 discloses a plate body that is arranged on a mounting table on which a suspended load that is suspended by a wire is placed and is supported so as to be movable up and down and to be opposed to the lower surface of the suspended load. And a spring member interposed between the mounting table and the plate body to push up the plate body and press the wire against the lower surface of the hanging load when the hanging load is placed on the mounting table. An apparatus for preventing the center of a wire from being displaced by preventing the wire from shifting in the center direction is disclosed.

In Patent Document 2, a pair of suspension beams are suspended on a crane hook via a wire, the suspension beams can be moved in the cross-sectional direction of the work roll, and the upper end of a substantially U-shaped wire ring is hooked on the suspension beam. A roll hanger for suspending a work roll with this wire ring, and when a downward load such as a work roll is applied to the wire ring, a pantograph mechanism is used to reduce the distance between the hanging beams so as to make the wire ring into a vertically long shape. A narrowing roll hanger is disclosed.

  As mentioned above, rolls are manufactured from the roll materials to the roll products in the factory consistently. At that time, the movement of the roll is suspended and transported via the wire suspended on the hook of the crane. , Moved to a predetermined work place, and placed on the mounting table. For this reason, when the wire center offset prevention device disclosed in Patent Document 1 is used, it is necessary to install this device on a mounting table at each work place, which is not convenient.

  In the roll hanger disclosed in Patent Document 2, the width of the U-shaped wire ring is changed by a pantograph mechanism, and the pantograph mechanism is opened and closed by a mechanical cylinder. However, when a wire is wound around a roll or the like, the workability is very poor and it cannot be easily handled.

  Therefore, the problem to be solved by the present invention is to provide a wire positioning method and a positioning jig that can easily adjust the balance position of a suspended load during a slinging operation of hanging a suspended load with a wire. It is in.

  In order to solve the above-described problems, the present invention provides a method for positioning a wire during a slinging operation in which a wire suspended by a hook such as a crane is hung on a suspended load and the suspended load is suspended. In the meantime, the interval between the wires hung on the suspended load is adjusted by a positioning jig that is hung on the wire.

  In this positioning method, the distance between the wires suspended on the suspended load can be adjusted by moving the positioning jig suspended on the wires up and down between the hook and the suspended load.

  Further, the present invention provides a wire positioning jig for hanging a wire that is suspended by a hook of a crane or the like and suspends the suspended load between the hook and the suspended load. The present invention is characterized in that a latch member that adjusts the interval between the wires by hooking on the wire that is hung on the suspended load is provided at both ends.

  In this positioning jig, the hook members at both ends are preferably joined by spring members to facilitate adjustment of the gap between the wires, and are preferably formed in a U shape so as not to easily come off the wire. .

  According to the present invention, the balance position of a suspended load can be easily adjusted during a slinging operation in which the suspended load is suspended by a wire, and an accident in which a hand is caught between the wire and the suspended load does not occur.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a front view showing a roll staking operation using the positioning jig of the present invention, and FIG. 2 is a view taken along the line AA of FIG. FIG. 3 shows a method for adjusting the looseness of the wire using the positioning jig of the present invention, and FIG. 4 shows details of the positioning jig of the present invention.

  As shown in FIG. 1, in the roll slinging operation, the roll 1 on the mounting table 4 is suspended from the two wires 2. That is, one wire 2 is stretched over one side of the roll 1, and the wire 2 is latched on the hook 3 of the crane. Another wire 2 is hung on the other side of the roll 1 and similarly hooked on the hook 3. The position where each wire 2 is passed over the roll 1 is set in consideration of the suspension point balance of the roll 1.

  In the present invention, the positioning jig 5 of the present invention is disposed between each wire 2 and the roll 1. As shown in FIG. 4, the positioning jig 5 includes latching members 7 at both ends thereof. The base end side of each latching member 7 is connected by a spring member 6, and the distal end side is formed in a U shape and is latched on the wire 2. The proximal end sides of the spring member 6 and the latch member 7 are housed in the guide pipe 8 and protected.

  Therefore, by holding the guide pipe 8 and moving the positioning jig 5 up and down, the interval between the wires 2 can be adjusted, and loosening can be prevented. Further, even if the size of the suspended load (roll 1) changes and the interval between the wires 2 changes, the change can be accommodated by the expansion and contraction of the spring member 6 built in the positioning jig 5. Thus, the loosening of the wire 2 can be prevented and a safe staking operation can be performed only by setting the positioning jig 5 including the spring member 6 on the wired wire 2.

  The width between the wires varies depending on the member to be struck. For example, the distance between wires when staking a large-diameter roll is different from the distance between wires when staking a small-diameter roll. The positioning jig 5 of the present invention shown in FIG. 4 can cope with a change in the length L of the latching member 7 by keeping the length a of the spring member 6 constant even if the distance W between the wires changes. . In order to make the length of the guide pipe 8 that houses the spring member 6 easy to work, it is sufficient that the worker has a length necessary for the operator to move up and down. Therefore, the length of the guide pipe 8 is set to about 300 to 600 mm.

  The present invention is not limited to roll staking work, and can be applied to various staking work performed by hanging a wire on a suspended load.

It is a front view which shows the roll slinging operation | work using the positioning jig of this invention. It is an AA arrow line view of FIG. It is a figure which shows the method of adjusting the slack of a wire with the positioning jig of this invention. FIG. 4 is a diagram showing details of the positioning jig of the present invention.
