Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for simply extracting fuel from a fuel tank of a scrap car and a fuel extracting device used directly for carrying out the invention of this method.

[0002]

2. Description of the Related Art Generally, scrapped cars are treated as metal scrap.
For example, it is well known that a press or the like is used for reusing. As a pretreatment for reusing a scrap car, gasoline, which is a fuel in the fuel tank of the scrap car, must be extracted from the fuel tank in advance in order to avoid the risk of explosion. The conventional extraction method is, for example, a method of removing the fuel by removing the fuel tank from the abandoned car, and without removing the fuel tank, make a hole in the fuel tank from the bottom of the fuel tank with a hand-held drilling tool to remove gasoline. As another method, the hydraulic pressure is used from below the fuel tank to extend the ram of the cylinder and forcibly make a hole in the fuel tank with the blade of the ram tip.

[0003]

However, in the method of removing the fuel tank, the work is inefficient and excessively heavy due to the time-consuming work of removing the fuel tank and carrying it to a predetermined place. In the method, since the wall of the fuel tank has high rigidity, it is not easy to make a hole in the wall, and it takes a lot of labor and time in combination with the manual work, and the hydraulic method also requires a large amount of hydraulic pressure. If necessary, the equipment will be large and the equipment cost will be high. In the method of penetrating the wall of the fuel tank, since the rising portion is formed at the inner peripheral edge of the vent hole toward the inside of the fuel tank, all the gasoline in the fuel tank does not escape, and a part of it remains in the fuel tank, There is a drawback that it poses a danger during processing such as pressing.

An object of the present invention is to make it possible to extract fuel from a fuel tank easily, quickly, efficiently, and at low cost and reliably.

[0005]

The first feature of the method for removing fuel from the fuel tank of a scrap car according to the present invention is that the scrap car is disposed above the receiving tank, and the scraping blade of the punching tool is erected on the receiving tank. This is where the fuel tank of the scrap car is made to face, then the scrap car is dropped, and the fuel tank is struck against the punching blade to make a hole in the fuel tank and discharge the fuel in the fuel tank into the receiving tank. . By moving the scrap car up and down several times, the rising part around the hole is formed outside the tank by the jaw part provided at the lower part of the drilling blade.

A second feature of the method for removing fuel from a fuel tank of a scrap car according to the present invention is that a scrap car is arranged above a receiving tank held by a fork of a forklift, and a punching blade of a punching tool that stands upright on the receiving tank. After facing the fuel tank of the scrap car, drop the scrap car and hit the fuel tank against the hole punching blade to make a hole in the fuel tank and discharge the fuel in the fuel tank into the receiving tank. Is moved up and down to form a rising portion around the hole on the outer side of the tank by a jaw portion provided at the lower portion of the drilling blade.

The fuel removal device for a fuel tank of a scrap car according to the present invention is used for the method for removing fuel from a fuel tank of a scrap car, and includes a holding device, a receiving tank held by the holding device, and the receiving tank. And a piercing tool standing upright. The piercing tool is provided with a piercing blade, and the piercing blade has a jaw portion formed at a lower portion thereof. In order to improve workability in this fuel extraction device, a forklift is used as a holding device, and this forklift is provided with a fork that can be moved up and down by the operation of a mast cylinder on the front side of the mast. It may support the receiving tank.

[0008]

[Operation] By dropping the scrap car, the fuel tank hits the punching blade due to its own weight and the hole can be easily drilled. The fuel is discharged from the hole formed in the fuel tank to the receiving tank as it is, and the fuel discharging process is simplified. Become. The hole is made large by the punching blade so that the fuel can be discharged smoothly, and the rising portion of the through hole projects to the outside of the fuel tank due to the presence of the jaw, so that the rising portion does not hinder the discharge of fuel.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. First, a fuel removing device for a fuel tank of a scrap car will be described, and then a fuel removing method will be described.

In the fuel extraction device, a mast 2 is erected on the front side of the forklift 1 as shown in FIG.
A fork 3 projects toward the front of the mast. The fork 3 moves up and down along the lift 2 by the expansion and contraction of the operating rod of the lift cylinder 4. The lift 3 can be tilted back and forth by expanding and contracting the rod of the chilled cylinder 5.

The fork 3 holds a receiving tank 6 that temporarily receives gasoline, which is the fuel discharged from the fuel tank T. As shown in FIGS. 2 and 3, the receiving tank 6 is formed in a box shape, and a box-shaped receiving auxiliary tank 6a is also provided in the substantially central portion of the bottom. The gasoline that accumulates in this auxiliary tank can be bent by opening and closing the valve 7
Through a storage tank (not shown). Further, between the pair of holding portions 3a, 3a of the fork 3 straddling the opening of the receiving tank 6, a groove-shaped support base 8 is provided so as to divide the opening of the receiving tank into two as shown in FIG. Both ends of this support stand are bolted to the holding part.
Fixed by

A drilling tool 10 is erected in the middle of the support base 8 corresponding to the position of the center of the receiving tank 6. The punching tool 10 is such that the lower end of a rod-shaped blade 10b is screwed into the upper end of a column 10a, and an arrowhead-shaped punching blade 10c is provided at the upper end of this blade. The lower part of the drilling tool 10 is fixed to the support base 8 by bolts 11. The blade body 10b can be removed from the support column 10a by loosening the nut 12, and can be replaced if necessary. The punching blade 10c is formed by combining triangular steel plates in a cross shape as shown in FIGS.

Next, the fuel extraction method will be explained using the extraction device of the above example. First, as shown in FIG. 1, the lift cylinder 4 of the forklift 1 is operated to operate the fork 3
When the receiving tank 6 is raised to a predetermined height via
When the operation is stopped, the position of the receiving tank is fixed. Then, the scrap car C is placed on the fork F of the other forklift L, and the fork is lifted to adjust the position of the scrap car so that the fuel tank T of the scrap car is located right above the drilling blade 10c of the drilling tool 10.

After the adjustment, the lift cylinder S of the forklift L is operated to lower the scrapped vehicle C, and the fuel tank T
Is struck against the drilling blade 10c of the drilling tool 10, and the same operation is repeated by repeatedly expanding and contracting the rod of the lift cylinder S and moving the scrap car C up and down several times. In this process, the fuel tank T is vigorously punched by the weight of the scrapped vehicle C.
Since it hits against the hole-drilling blade 10c, the wall of the fuel tank is pierced by the hole-drilling blade and a hole Ta is opened in the fuel tank. At the same time when the holes are opened, the gasoline in the fuel tank T is discharged into the receiving tank 6. The gasoline dropped into the receiving tank 6 can be opened by opening the valve.
It flows from the auxiliary tank 6a through the hose 7 and is stored in the storage tank. Since the receiving tank 6 is fixed at a high position, gasoline is smoothly discharged from the auxiliary tank 6a to the storage tank. Then, the lift cylinder S is operated to raise the scrap car C together with the fork F to the initial position, and the work of extracting the gasoline from the fuel tank is completed.

When the scrap car C is moved up and down several times, the piercing blade 10c is provided at the bottom with a jaw portion 10c1 as shown in FIG.
As shown in FIG. 5, the fuel tank T is provided with a large hole Ta, and at the periphery of this hole, a bent rising portion Tb is formed outside the fuel tank. All the gasoline inside will be discharged to the receiving tank 6 outside the fuel tank.

Further, by attaching the receiving tank 6 to the forklift 1, it is convenient that the fuel tank can be degassed at an appropriate position, and the drop impact of the scrapped vehicle C on the receiving tank 6 through the punching tool 10 is prevented. The lift cylinder 4 has the advantage of being alleviated. of course,
The present invention is not limited to the combination of the receiving tank 6 and the forklift 1, but a supporting base for the receiving tank 6 may be provided in place of the forklift. In this case, for example, a hydraulic cylinder is interposed in the supporting base. The receiving tank may be connected. It is desirable that the receiving tank 6 be formed to be somewhat large in order to prevent the exhausted gasoline from scattering.

The structure of the punching blade 10c is not limited to the combination of steel plates as in the above example, but may be a conical shape, for example.

[0018]

According to the present invention, since it is possible to make a hole in the fuel tank of a scrap car by utilizing the dead weight of the scrap car, the drilling work can be performed more easily, quickly, efficiently, and at lower cost than the conventional example. In addition, since the hole is drilled using a piercing blade with a chin at the bottom, a large hole can be drilled and a rising part is formed outside the fuel tank at the periphery of the hole, so that all the fuel in the fuel tank is smooth. It can be safely discharged to work such as pressing a scrap car.
