Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to an improvement of a hanging material used for loading and unloading a plate-like heavy material such as a steel plate.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, this type of plate material suspending device is generally used. That is, a pair of hook-shaped hackers 7 are suspended from the both sides in the width direction of the suspension beam 1 suspended horizontally on a cargo handling hook of a crane or the like by wires 6 at substantially equal intervals. It is.

[0003] In order to lift a plate material with this hanging tool, first, the hanging tool is suspended above the plate material 9 by operating a crane or the like, and each pair of hackers 7 hung from the hanging beam 1 is individually moved. Land on both sides of the plate to be lifted. Then, each of these hackers 7 is manually hung by a slinging operator on both side surfaces of the plate material. Then, in this state, the lifting tool is slightly raised, and after checking the degree of engagement of each hacker 7, the lifting tool is raised in earnest to lift the plate material.

[0004]

[Problems to be solved by the invention]

 However, in such a lifting operation, since each of the above hackers 7 is a considerable weight (about 10 kg), these are lifted by hand and hung on the plate material 9, and furthermore, the condition of each hacker is checked. It was a heavy labor burden for the slingers who kept holding until they were released.

[0005] In addition, one rigging worker is usually in charge of rigging a pair of hackers 7, but with this kind of hanging tool, a large number of pairs of hackers 7 (4 in the illustrated example). Pairs), which required the same number of personnel as the number of pairs and the work efficiency was poor.

[0006] The present invention has been made to solve such a problem, and the labor burden required for the above-mentioned slinging work is significantly reduced, and further, regardless of the number of pairs of hackers, The purpose of the present invention is to provide a hanger that can be slung by two workers at all times.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a plate material suspending device comprising a plurality of suspending beams which are vertically lifted by a crane or the like, and pairs suspended at substantially equal intervals by wires from both side surfaces in the width direction of the suspending beams. A pair of hook-shaped hackers and a pair of horizontal pipe members respectively connecting the hackers suspended from the same side of the suspension beam, and between the pair of pipe members and both side surfaces of the suspension beam, It consists of a plurality of pairs of support wires, each of which is stretched at substantially equal intervals, and each of the support wires is adjustable in tension angle, and each of the pipe materials is adjusted by a spring balancer incorporated in the wire. It is structured to reduce the lifting and lowering effort.

[0008] In the present invention, it is preferable that the pair of pipe members have an extensible structure that can cope with various lengths of the plate material to be lifted.

[0009]

[Embodiment of the invention]

 FIG. 1 shows an example of a plate hanging device according to the present invention, in which 1 is a hanging beam that is lifted and lowered horizontally by a crane or the like, and 7 is a wire 6 from both side surfaces of the hanging beam 1 in the width direction. A plurality of pairs of hook-shaped hackers suspended at intervals, 8 is a pair of horizontal pipe members respectively connecting hackers 7 suspended from the same side surface of the suspension beam, and 12 is a pair of pipe members 8. A pair of a plurality of pairs of support wires, which are stretched at substantially equal intervals, respectively, between the pair of support wires and both side surfaces of the suspension beam 1 are shown.

That is, the suspension beam 1 is formed of a steel square tube having a length L of about 7.200 mm, and two eye plates 2 are provided in parallel at the center of the upper surface. These eye plates 2 are for suspending the suspension beam 1 horizontally on a loading hook 4 such as a crane by a wire sling 3 and moving the suspension beam up and down. A plurality of hooks 5 (four on each side in the illustrated example) are provided on both sides of the suspension beam 1 in the width W direction at substantially the same positions.

A hacker 7 is suspended from each hook 5 by a wire 6 of a required length. These hackers 7 are formed by bending a steel bar, and have a hook 7 whose tip 7 ′ is bent horizontally. The hackers 7 suspended at the same position from both side surfaces of the suspension beam 1 form a pair in which the tip portions 7 'face each other. Therefore, in the case of the illustrated example, four pairs of hackers are provided at substantially equal intervals.

As described above, each pair of hackers 7 that hang from the same side surface of the suspension beam 1 is a pair of pipe members 8 horizontally fixed to the rear side thereof. Are connected together.

In the illustrated example, the pair of pipe members 8 is formed of a square steel pipe and is configured to be expandable and contractible. That is, in these pipe members 8, a square steel pipe 8a having a relatively large diameter and a required length is disposed at the center, and small-diameter square steel pipes 8b and 8c are inserted and removed as shown by arrows in the openings at both ends. The pipes can be inserted freely so that the entire length of the pipe can be expanded and contracted by these operations. In this case, hackers 7 'suspended from the suspension beam 1 at both front and rear ends are fixed to the square steel pipes 8B and 8H which can freely take in and out of the respective pipe members 8. The position can be adjusted back and forth, and can correspond to various lengths of the plate material 9 to be lifted.

The paired pipe members 8 are provided with a plurality (three in the illustrated example) of eye plates 10 at substantially equal intervals in the length direction. Further, dedicated hooks 11 are provided on both side surfaces in the width direction of the suspension beam 1 at positions facing the above-mentioned eye plates. A support wire 12 is stretched between the opposing eye plate 10 and hook 11. These support wires 12 support the pair of pipe members 8 on both side surfaces of the suspension beam 1, respectively, and those facing each other at the same position on both sides are paired with each other. Therefore, in the illustrated example, three pairs of support wires 12 are provided at substantially equal intervals.

In the illustrated example, the pair of support wires 12 are divided into an upper support wire 12a and a lower support wire 12b on the way, and connected via a tension angle adjusting beam 13. . That is, as shown in FIG. 2 and FIG. 3, the divided upper supporting wires 12a are connected to the hanging eye plates 14 provided on both sides of the upper surface of the tension adjusting beam 13, respectively. The lower supporting wire 12b is connected to one of 15 rows of tension angle adjusting plates 15 arranged in plural on each side of the lower surface of the beam 13. Therefore, each support wire 12 can freely adjust the tension angle θ by changing the connection of the lower support wire 12 b to another eye plate 15 in the same row.

Each of the pair of support wires 12 incorporates a spring balancer 16. As shown in FIG. 4, when the wire 18 wound around the drum 17 is pulled out, the drum 17 rotates, and the spring balancer 19 fixed to the rotation shaft 18 is urged by the spring balancer 16 so that the spring 18 is urged. When the pull-out force of the spring is weakened, the drum 17 rotates in reverse by the force of the biased spring 19, and the wire 18 is rewound, so that the spring force of the spring 19 can be adjusted within a certain range. Has become. Therefore, if a heavy object is hung on the wire 18 and the spring force of the mainspring 19 is made equal to its weight, the operation of raising and lowering the heavy object can be performed with a small amount of labor by balancing the forces. As this kind of spring balancer 16, various types of lifting and lowering operation aids for a heavy object having different spring force adjustment ranges are commercially available, and a hanger 20 is provided on the upper part of the case in advance, and an eggplant 21 is provided on the tip of the wire 18 in advance. ing.

In the illustrated example, the above-mentioned spring balancer 16 is hung on the tension angle adjusting beam 13 by the lower support wire 12 b, and the wire 18 provided in the spring balancer 16 is directly attached to the eye plate 10 of the pipe 8. By being connected, each support wire 12 is incorporated. These spring balancers 16 assist the worker in raising and lowering the pair of pipe members 8, and the total weight added to each of the pipe members 8 (that is, the weight of the pipe member 8 itself and the weight fixed to the pipe member). (Having the total weight of four hackers 7 and the weight of four wires suspending these hackers) is selected.

In order to use the plate material suspending tool having the above configuration, the tension angle θ of each pair of support wires 12 is adjusted in advance according to the width Wa of the plate material 9 to be lifted. In other words, the connection position of the lower support wire 12 and the beam 13 for adjusting the angle of inclination is changed to adjust the angle of inclination θ to a minimum. Further, both ends 8b and 8h of the pair of pipe members 8 are extended or contracted so that the positions of the hackers 7 'at both ends are adjusted to the length La of the plate material 9. One slinging worker is placed on each side of the length of the plate 9 to be lifted.

Then, the hanging tool is suspended on a cargo handling hook such as a crane, and is moved above the above-mentioned plate material 9 placed on the ground to be suspended. When the hanging tool is hung on the plate member 9, the two slingers arranged as described above respectively hold the corresponding end portions 8b and 8c of the pair of pipe members 8 with both hands. . Then, in cooperation with each other, the two pipe members 8 are respectively arranged along both sides in the width direction of the plate member 9, and the hackers 7 provided for the pipe members are hung on both side portions. In this state, the lifting device is slightly raised, and after checking the degree of engagement of each hacker 7, the lifting device is raised in earnest to lift the plate.

In the above-described series of slinging operations, the pair of pipe members 8 of the hanging tool suspended on the ground are all attached to the hanging beam 1 by a plurality of supporting wires 12 incorporating a spring balancer 16. Since it is supported, an operator who grips it at both ends and operates it up and down to sling the hacker 7 on the plate material 9 hardly feels its weight. Therefore, the labor burden required for this type of slinging work is significantly reduced, and workability is greatly improved.

[0021]

[Effect of the invention]

 As described above, according to the plate hanging device of the present invention, it is possible for only two workers to sling a large number of hackers, which are heavy objects, which conventionally required many workers. Moreover, it can be performed easily without a large labor burden. Therefore, workability is greatly improved. In addition, health problems such as low back pain that are likely to occur in this type of worker are prevented.
