DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing a wire harness of a scrapped vehicle such as an automobile from a scrapped vehicle body for recycling.

[0002]

2. Description of the Related Art With the growing awareness of environmental issues,
Interest in the effective use of resources is increasing. Such problems are no exception for discarded vehicles. In particular, the amount of wire harnesses used in recent electronically controlled vehicles is enormous, and at present it cannot be ignored.

Conventionally, when removing a wire harness from a discarded vehicle body, a J-shaped hook has been hooked on the wire harness and lifted up by a lifting device such as a crane. However, in such a method, when removing the wire harness, the wire harness often slips at a portion where the J-shaped hook is hooked, and pulling up often fails. In addition, it is necessary to select an appropriate hook point so as not to cause a side slip, and the efficiency of workability is low.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned disadvantages of the prior art, and there is no side slip when the wire harness is removed from the scrapping vehicle, and the hook point of the wire harness can be set at an arbitrary point. It is an object of the present invention to provide a method for removing a wire harness that can be used as a part and improve workability.

[0005]

According to the present invention, the following technical means are provided to solve the above-mentioned problems. (1) A method of removing a wire harness from a vehicle by hooking the wire harness on a hook of a lifting device in a vehicle disassembly step, wherein a hanging member having hooks on both ends of the hook and having a main body in a string shape or a band shape is provided. And removing the wire harness by winding the hanging tool body around the wire harness and hooking both hooks on a hook of a lifting device to pull up the wire harness. (2) In a method of removing a wire harness from a vehicle by hooking the wire harness on a hook of a lifting device in a vehicle disassembly process, using a hanging member that is a ring-shaped string or band-shaped member, While being wound around the wire harness, hooks to the hooks are formed at both ends by the string-shaped or band-shaped members, and both hooks are hooked on the hooks of the lifting device and pulled up to remove the wire harness. Characteristic wire harness removal method.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. The present invention relates to a method for removing a wire harness from a vehicle by hooking the wire harness on a hook of a lifting device in a dismantling process of the vehicle,
A hook having hook portions at both ends is used, and a main body in the form of a string or a band is used.The main body of the hook is wound around a wire harness, and both hook portions are hooked on hooks of a lifting device. The wire harness is removed by pulling up.

FIG. 1 shows the structure of a hanger used in an embodiment of the present invention. In the figure, reference numeral 1 denotes a hanging device, 2 denotes a hanging device main body, which is composed of a string-shaped member. At both ends of the hanging tool main body 2, hooks 3A and 3B for hooking the hanging tool 1 on a hook of a lifting device are attached. Also,
The hooks 3A and 3B are formed with circular openings (eye) 4A and 4B for hooking.

[0008] The hanging body 2 is wound around the wire harness when the wire harness is detached, and therefore needs to be flexible enough to be wound. Moreover, the hanging member main body 2 has a high coefficient of friction and a high flexibility (soft) as described above, and has a strength (500 to 500 in tensile strength) that is not torn when the wire harness is removed.
0 kg / mm ² ). Furthermore, those that can withstand repeated use are advantageous in view of economics. Various appropriate materials can be used as long as they have such properties, but specific examples include nylon and nylon.
Various string-like members such as ropes or ropes made of high-strength fibers such as Kevlar, metal wires, and leather strings can be used. The length of the hanger main body 2 can be set to an appropriate length according to the type, size, length, and the like of the wire harness to be removed.

The hooks 3A and 3B need to have such a strength that the hooks 3A and 3B are not broken when they are hooked on a hook of a lifting device when the wire harness is removed. Also, the openings 4A of the hooks 3A, 3B,
4B must be large enough to allow the hook of the lifting device to be inserted. If such, metal,
Various materials such as plastic can be used. In the illustrated example, the openings 4A and 4B have a circular ring shape. However, the openings 4A and 4B may have a ring shape having various outer shapes such as an ellipse, a rectangle, and a polygon.

Various known connection methods, such as caulking, fusion, screwing, and piveting, can be used to connect the hanging body 2 to the hooks 3A, 3B.

At the time of use, the hanging tool 1 is provided with a hook 3
A and 3B are connected to the hooks of the lifting device. As the lifting device, various types of cranes and chain blocks, as well as a combination of a forklift and a connecting wire or chain can be used.

Next, the operation of removing the wire harness using the hanging tool 1 will be described. FIG. 2 is a schematic diagram showing a state of removing the wire harness. In the figure, reference numeral 5 denotes a wire harness to be removed, and reference numeral 6 denotes a hook of a lifting device.
In removing the wire harness 5, the main body 2 of the hanging tool 1 is wound around the wire harness 5, as shown in FIG. . Thereafter, the hanging tool 1 is pulled up by the mechanical force of the lifting device, and the tightening force of the hanging tool 1 causes the hanging tool 1 to continue to pull the wire harness 5 without skidding, and the wire harness 5 is removed. In this removal, it is not necessary to select a point where the wire harness 5 is hooked as in the related art, so that work efficiency is improved.

FIGS. 3A and 3B show an example in which a wire harness is detached by using a hanger whose hook portion is integral with the hanger main body. Even with such a structure, similar to the case of using the hanging tool shown in FIGS. 1 and 2,
Excellent operational effects can be obtained.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications and changes can be made. First, in the above, a rope-shaped member such as a rope and a rope was used as the hanging member body, but a chain, a leather,
A belt-like member made of various materials such as plastic can also be used. Further, in the above embodiment, the hook portion has a ring shape, but may have a hook shape as shown in FIG. Further, a string-shaped ring as shown in FIG. 5 or a ring made of a chain as shown in FIG. 6 is used as the suspending device, and the doubled portion is wound around the wire harness as a suspending device body at the time of removal. Alternatively, a hooking portion having an opening may be formed by twisting both ends, and the portion may be used as a hooking portion to be hooked on a hook of a lifting device for removal work.

[0015]

According to the present invention, since the above-mentioned method is adopted, there is no side slip when the wire harness is removed from the discarded vehicle, and the hook point of the wire harness can be set at an arbitrary point, thereby improving workability. Can be improved.
