Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrap dismantling vehicle suitable for dismantling various scraps, particularly automobiles.

[0002]

2. Description of the Related Art Conventionally, dismantling work of automobile scrap has
The piled up scrapped vehicle bodies are lowered one by one by a crane, transported sideways by a transport vehicle, and cut to an appropriate size by a cutting torch or the like at a work site of a scrap factory, or engine parts are removed.

Further, as disclosed in Japanese Patent Publication No. 3-78460, for example, a hydraulically operated boom having an opening and closing work tool at the tip is horizontally opened and closed on a vehicle body portion of a self-propelled vehicle provided with a turning and lowering capability. A disassembly device is also known in which a pair of opening / closing arms are attached and various work hands such as a holding tool for rotatably holding the scrap object and a split tool for breaking or crushing the object are attached to the opening / closing arm. With such a dismantling work vehicle, the dismantling work can be carried out efficiently and efficiently, and a certain amount of scrap can be separated and collected.

Further, with the recent rapid spread of automobiles, the number of scrapped vehicles is also increasing dramatically, and moreover, recent automobiles use many composite parts made of various materials. For this reason, the sorting work for each material for each part being dismantled is becoming extremely complicated.

In recent years, dismantling of other scraps, such as household electrical appliances and construction waste, has been excluded from normal handling, and various scraps are accumulated in various places and are in a state of waiting for dismantling.

[0006] Among various types of scrap, there is a type in which dissimilar metal parts to be separated and recovered, such as a pipe portion and a valve portion, are small, hard and firmly fixed, such as scraps in water distribution piping. However, since such objects cannot be handled by the conventional dismantling work vehicle, they are often disposed of without being separated and collected. In this case, the piping is made of relatively inexpensive steel scrap, and the valve is made of relatively expensive gunmetal, which can be economically obtained if separated and collected. Is wasted.

Further, for example, in the case of a scrap such as an electric washing machine, the outer casing and the washing tub and the inner electric motor must be separated and dismantled. In an electric refrigerator, the casing and the inner heat insulating material, the compressor and the like are separated. However, with a conventional dismantling work vehicle, it is not possible to directly take out the electric motor and compressor inside these with the opening and closing work tool at the end of the boom. Processing was taking place.

Under these circumstances, for example, Japanese Patent Laid-Open No. 7-2
As disclosed in Japanese Patent No. 4624, the handling range of the separation and collection of scrap objects is expanded in terms of size and strength, and the sorting and dismantling work of various types of scrap including scrap cars is efficiently performed at those collecting places. A versatile scrap dismantling work vehicle capable of performing such tasks has been proposed.

[0009]

However, for example, large tires for excavators are twice as large as large trucks, and it has been necessary to cut them into small pieces for landfill and incineration. For example, in order to cut such a large tire, the tire is pulled in the radial direction, and the tire is cut by a cutting blade to reduce the size to 1/2 and then further cut to reduce the size to 1/4. I needed to do that.

According to the present invention, not only is it possible to efficiently separate and disassemble various kinds of scraps such as scraps of household electric appliances at an accumulation place thereof, but also to efficiently cut large tires. It is an object of the present invention to provide a scrap dismantling work vehicle.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, an undulating hydraulically operated boom is pivotably mounted on the body of a self-propelled vehicle,
The boom tip is provided with a scrap dismantling work pens that is opened and closed by hydraulic pressure by remote control, and a pair of left and right arms that can be opened and closed at the front or rear of the vehicle body is provided so as to be able to move up and down by a hoisting drive mechanism. Since a clamp for clamping the scrap object between the arms is attached to the arm, it is transported by truck to the place where scraps such as junk cars to be dismantled are accumulated and dismantled on site When performing the work, the dismantling work can be performed by the turning hydraulically operated boom of the vehicle and the pair of power drive arms with the clamps with an optimum holding function according to the size of the scrap.

Incidentally, the pair of arms can be set up along the vehicle body when the dismantling work vehicle is transferred, and the holding device is disclosed in Japanese Patent Publication No. 3-78460 or JP-A-7-24624. Various clamping work hands as shown can be used.

In the dismantling operation, the pair of arms press down, for example, a junk car placed upside down by its raising and lowering operation, and in this state, for example, the engine of the junk car is cut and torn off by the dismantling work pliers by boom operation. For example, the scrap parts of each part are separately removed under a stable scrap holding state. The removed engine is caught by the pliers and placed in another place by the boom turning, and is subjected to the next engine dismantling work.

In the tire cutting operation, the inner diameter of the tire is hooked on a pair of projecting tools erected on the upper part of the holding tool, and the arm is opened to pull the tire in the radial direction. By breaking the gap with the dismantling work pliers at the end of the boom, even a large tire can be cut efficiently.

In the dismantling work of electric appliances, for example,
By inserting a pair of projecting tools set up on the upper part of the clamp into the bottom opening of the electric washing machine and opening the arm, the electric washing machine can be opened and disassembled from the inside, and the electric motor inside the boom tip It can be exposed so that it can be easily grasped by the dismantling work pens. This eliminates the need for manual disassembly of the housing and the like, and allows the separate disassembly of the built-in components of the scrap object, which was conventionally difficult to handle, by mechanized work.

In a preferred aspect of the present invention, an upper portion of the holding tool on which the projecting tool is erected has an outer shape capable of being fitted to a torus cross section of a tire broken in a radial direction. Thereby, in the tire cutting work, it is easy to further cut the tire, which has been cut in the approximate half by the puncher while being pulled in the radial direction by the pair of projecting tools, further in the approximate quarter.

Specifically, the upper part of the projecting tool and the upper part of the holding tool are fitted into each of two torus sections appearing in the tire cut in half. Then, by opening the arm, the tire fragments passed in a bridge shape are pulled in a direction in which the torus section is separated. By breaking the gap with the pliers at the end of the boom, even a large tire can be cut efficiently.

In a further preferred aspect of the present invention, a pair of projecting tools are provided in a direction away from each other as going upward. Thereby, when the tire piece passed in the bridge shape is pulled in the direction in which the torus cross section is separated, the tire piece is less likely to fall out from the upper portion of the projecting tool and the holding tool, and the tire is further cut into approximately 1/4. It becomes easier.

According to another aspect of the present invention, a hydraulically operated boom that can be raised and lowered is pivotably mounted on a vehicle body of a self-propelled vehicle, and a scrap dismantling work plier that is hydraulically opened and closed by remote control at the end of the boom is provided. A pair of left and right arms that can be opened and closed can be opened and closed by a hoisting drive mechanism at the front or rear part of the vehicle body, and a holding tool for holding a scrap object between the arms is attached to each of the arms so as to face each other. The tips of a pair of left and right arms of the scrap dismantling work vehicle are bent in directions away from each other. Thereby, scrap during the dismantling operation can be stably suppressed, and the dismantling operation can be performed efficiently.
