DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic oil recovery device for extracting hydraulic oil from a hydraulic shock absorber disposed of.

[0002]

2. Description of the Related Art In recent years, in the disposal of what is called industrial waste, there is a tendency that it is required to properly dispose of the waste. Therefore, for example, vehicles are scrapped. However, there is a view that this is performed after removing the hydraulic shock absorber from the vehicle.

On the other hand, when disposing of a hydraulic shock absorber that has been removed from a vehicle or the like, the hydraulic fluid inside the hydraulic shock absorber is removed in advance, and then crushed by a press machine to form a so-called scrap.

A conventional measure for draining the hydraulic oil in the hydraulic shock absorber is to break the hydraulic shock absorber, that is, when the gas pressure is present in the hydraulic shock absorber. In some cases, this gas pressure may cause the hydraulic oil to be scattered, causing oil stains to occur in the surroundings.

In order to prevent the hydraulic oil from being scattered, for example, as shown in FIG. 2, a drain pipe 2 serving as a pipeline is connected to a discharge hole 1a opened in the hydraulic shock absorber 1, and the drain pipe 2 It can be proposed to guide the leading end into the external tank 3 to collect the hydraulic oil without scattering.

Incidentally, when there is no gas pressure in the hydraulic shock absorber 1, there is no fear of scattering of the hydraulic oil. However, in order to prevent the so-called drifting of the surroundings from occurring, the hydraulic oil is recovered in the same manner as described above. Will be done.

However, even if the hydraulic oil is recovered as described above, if there is a gas pressure in the hydraulic shock absorber 1, the hydraulic oil in the hydraulic shock absorber 1 is transferred into the tank 3 by this gas pressure. Although the oil can be ejected, after the gas pressure is released, the hydraulic oil is positively discharged by so-called pumping operation in which the hydraulic shock absorber 1 is expanded and contracted, that is, the piston rod 1c is made to protrude and retract from the cylinder 1b. You have to do it.

If there is no gas pressure in the hydraulic shock absorber 1 from the beginning, the pumping operation must be performed from the beginning to discharge the working oil.

As a result, in the case of the above-mentioned proposed measure, in order to completely recover the hydraulic oil in the hydraulic shock absorber 1,
It is necessary to operate the hydraulic shock absorber 1 by pumping, and in some cases, it is necessary to supply a new gas pressure or the like, and there is a concern that the operation of collecting the hydraulic oil may be troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to scatter hydraulic oil when recovering hydraulic oil from a discarded hydraulic shock absorber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiment. The principle of the hydraulic oil recovery device according to the present invention is to discharge hydraulic oil in a hydraulic shock absorber by using centrifugal force. Then you are right there.

In the embodiment of the hydraulic oil recovery device according to the present invention, when the hydraulic oil in the hydraulic shock absorber is discharged by using the centrifugal force, the hydraulic oil is prevented from being scattered and is discharged. As shown in FIG. 1, the hydraulic oil recovery device according to one embodiment includes a casing 4, a turntable 5 and a recovery unit 6 disposed in the casing 4. Suppose you have.

As described above, since the casing 4 prevents the hydraulic oil from scattering, it is sufficient if the casing 4 is set so as to form an enclosed space called a so-called room. Can be set arbitrarily.

However, in the casing 4, it is necessary to take the hydraulic shock absorber 1 in and out, and it is a matter of course that the casing 4 normally has an opening 4a through which the hydraulic shock absorber 1 can be taken in and out. However, at this time, the opening 4
It is preferable that the opening / closing door 7 is provided at a, and that at least the opening / closing door 7 is formed of a material having high transparency.

When the door 7 is made of a highly transparent material, it is advantageous in that the condition in the casing 4 can be monitored through the door 7 and, therefore, the viewpoint of enabling the inside to be monitored. Therefore, it can be said that the required portion of the casing 4 may be formed of a material having high transparency.

It should be noted that, as is the case with this type of casing, even in this casing 4, the surroundings of the opening / closing door 7 and the opening 4a are formed under a so-called liquid leakage prevention structure. .

Incidentally, the casing 4 shown in the drawing has a horizontal separating portion 4b at an intermediate portion to divide the internal space into an upper side and a lower side. Although it is allowed to scatter, the interior space on the lower side is not affected by the influence and is set to be a so-called clean zone.

The turntable 5 is set so as to rotate while holding the hydraulic shock absorber 1 to generate a centrifugal force. In this embodiment, the holding state of the hydraulic shock absorber 1 is inclined. It is set to be in a state.

Regarding the reason, if the hydraulic shock absorber 1 rotates in a horizontal state when the turntable 5 rotates,
There is a disadvantage that the lateral dimension of the casing 4 must be set large so that the end of the hydraulic shock absorber 1 rotating in a horizontal state does not interfere.

On the other hand, if the hydraulic shock absorber 1 rotates upright when the turntable 5 rotates, it is advantageous in that the lateral dimension of the casing 4 can be set small.
There is a fear that the hydraulic oil in the hydraulic shock absorber 1 will not be completely discharged.

On the other hand, as in this embodiment,
When the hydraulic shock absorber 1 is set to rotate in an inclined state when the turntable 5 rotates, the lateral dimension of the casing 4 does not need to be set unnecessarily large, and
The hydraulic oil in the hydraulic shock absorber 1 can be completely discharged.

Therefore, the turntable 5 according to this embodiment is
Has a shaft portion 8 extending in the longitudinal direction and is set rotatable about an axis of the shaft portion 8, while an upper end portion provided on the upper end side of the shaft portion 8 is provided. The upper end of the hydraulic shock absorber 1 is connected to the stop portion 9, and the lower end of the hydraulic shock absorber 1 is connected to a lower end side locking portion 10 connected to the lower end side of the shaft portion 8, so that the hydraulic shock absorber 1 is inclined. It is set to be retained.

By the way, the turntable 5 according to this embodiment
Is set so as to be able to hold a plurality of hydraulic shock absorbers 1 at the same time, but it is not realistic from the point of the present invention, but it is not realistic.
May be set so that only one can be held.

The hydraulic shock absorber 1 held on the turntable 5
Is the posture when the cylinder body 1d side in which the hydraulic oil is stored is the lower end side, that is, when the so-called upright state is maintained.

The turntable 5 will be described briefly.
First, the shaft portion 8 is rotated by the drive of the electric motor 11 as a drive source connected to the lower end thereof, that is, the electric motor 11 disposed in the above-described clean zone.
In the illustrated embodiment, it is assumed that a support shaft 8a provided continuously is locked to the upper end of the casing 4 in order to rotate the upper end side in a stable state.

In the illustrated embodiment, the lower end side locking portion 10 is connected to a disk-shaped support portion 10a connected to the lower end of the shaft portion 8. However, since this support portion 10a is arranged to position the lower end side locking portion 10 at a predetermined position, instead of being formed in the above-mentioned disc shape, it is not shown, Needless to say, it may be formed in a so-called arm shape made of a rod-like body or the like.

If the lower end side locking portion 10 is connected to the support portion 10a formed in an arm shape, the lower end side locking portion 10 is connected to the support portion 10a formed in a disk shape. It can be said that it is preferable in that oil is less likely to accumulate on the support portion 10a and so-called oil drainage is improved, as compared with the case where it is performed.

Although not shown, it is assumed that the support portion 10a is formed in an arm shape and the base end thereof is pivotally supported by the shaft portion 8, so that the support portion 10a can be raised and lowered with respect to the shaft portion 8. When the hydraulic shock absorber 1 is set to be different, the lower end of the hydraulic shock absorber 1 can be connected to the lower end side locking portion 10 even when the length of the hydraulic shock absorber 1 varies. This is advantageous.

However, in this embodiment, since the turntable 5 is set so as to be able to hold the plurality of hydraulic shock absorbers 1, that is, together with the above-described upper end side locking portion 9, the lower end side engaging portion 9 is not required. In view of the fact that the same number of the stop portions 10 are set, it is easier to simultaneously connect the plurality of lower end side locking portions 10 when the support portion 10a is formed in a disk shape. This is advantageous.

Further, the upper end locking portion 9 and the lower end locking portion 10 effectively prevent the hydraulic shock absorber 1 from falling off when the turntable 5 rotates while holding the hydraulic shock absorber 1. It is assumed that the structure is set to obtain.

In the illustrated embodiment, the hydraulic shock absorber 1 is set to have a structure having pins 9a and 10a fitted to eyes (not shown) connected to upper and lower ends of the hydraulic shock absorber 1, respectively. Although it is intended to simplify the operation of attaching and detaching the shock absorber 1, the structure may be configured to have a chuck for holding the eye, so that the so-called holding property may be prioritized.

As to the upper end side locking portion 9, it is assumed that the upper end side locking portion 9 is directly connected to the shaft portion 8 as shown in the figure.
Similarly to the above, it is a matter of course that the supporting member may be provided in a disk-shaped supporting member or an arm-shaped supporting member having an appropriate diameter.

In the turntable 5, the lower end of the shaft portion 8, that is, the support portion 10a is connected to the casing 4 described above.
Is supported under the arrangement of the bearing 12 on the horizontal separating portion 4b.

The recovery means 6 is assumed to be set so as to recover the hydraulic oil discharged from the hydraulic shock absorber 1, and as shown in FIG.
It has a drain hole (not shown) formed in the horizontal isolation part 4b constituting the casing 4 and a drain pipe 2 which is a pipe connected to the drain hole. It is arranged to face the lower part of the turntable 5, that is, the inside of the collection tank 13 arranged in the clean zone.

By the way, in the illustrated embodiment,
A filter 14 is disposed in a drain hole formed in the horizontal isolation part 4b to prevent so-called dust from being mixed in the hydraulic oil collected in the collection tank 13. It goes without saying that the filter 14 may be omitted depending on the use of the oil and the processing of the recovered hydraulic oil.

The recovery of the hydraulic oil will be described with reference to FIG. 2. In FIG. 2, the tip of the drain pipe 2 extends to the outside, and the tip of the drain pipe 2 is placed in a tank 3 which is also installed outside. It goes without saying that you may be guided to.

In this case, although not shown, the base end of the drain pipe 2 may be directly connected to the casing 4 instead of the horizontal separating portion 4b of the casing 4.

In the hydraulic oil recovery device according to the present embodiment formed as described above, the discharge hole is formed at the lower end of the hydraulic shock absorber 1, that is, at the lower end of the cylinder body 1d which is the lower end at the time of setting. The hydraulic shock absorber 1 is held on the turntable 5 in an inclined state on condition that the hole 1a is opened.

When the turntable 5 is rotated after the discharge hole 1a is opened at the lower end of the cylinder body 1d, the hydraulic oil in the hydraulic shock absorber 1 is discharged by the centrifugal force generated at that time. The hydraulic oil will be swung out of the hydraulic shock absorber 1 through the hole 1a. Therefore, even when the hydraulic shock absorber 1 is of a type having no gas pressure, the hydraulic oil is forcibly discharged. .

The hydraulic oil discharged from the hydraulic shock absorber 1 is recovered by the recovery means 6, and the recovered hydraulic oil is reused, for example, by being mixed with heavy oil and used as fuel. Is achieved.

By the way, in the illustrated embodiment, the casing 4 holds the perforating means 15 and the perforating means 15 holds the hydraulic shock absorber 1 held on the turntable 5.
It is set so that the discharge hole 1a is formed in the cylinder body 1d which is the lower end member of the cylinder body.

At this time, it is preferable that the drilling means 15 is, for example, an electric drill, and this electric drill enables advance and retreat with respect to the casing 4 as shown by a double-headed arrow in the drawing. It is assumed that it is held so that

Therefore, in the hydraulic oil recovery apparatus according to the present embodiment in which the casing 4 is formed integrally with the perforating means 15, after the hydraulic shock absorber 1 is set on the turntable 5, the cylinder body The drain hole 1a can be opened at the lower end of the hydraulic shock absorber 1d.
Has a gas pressure inside, there is an advantage that the above-described discharge hole 1a can be opened while permitting the ejection of the hydraulic oil due to the gas pressure.

In the above-described embodiment, the hydraulic oil recovery device according to the present invention is formed as a so-called single unit. However, in consideration of the intention of the present invention, the hydraulic oil recovery device can It goes without saying that it may be provided integrally as an auxiliary mechanism in a scrapping press machine, and in this case, of course, the working effect of this hydraulic oil recovery device does not differ.

[0053]

As described above, according to the present invention, the hydraulic oil can be discharged from the casing and the discharged hydraulic oil can be collected. Work can be performed.

When the opening and closing door is provided at the opening of the casing and the opening and closing door is formed of a material having high transparency, the opening and closing door can function as a monitoring window for monitoring the condition in the casing. become.

In the case where the casing is divided into an upper side and a lower side by an internal horizontal isolation portion, the upper space is set to a space allowing the splash of the hydraulic oil, and the lower space is set to the space for the hydraulic oil. A clean zone that is not affected can be set, and an electric motor that rotates the turntable and a collection tank that constitutes a collection unit can be arranged in this clean zone without fear of oil contamination.

When the collecting means has a drain hole formed in the casing and a drain pipe connected to the drain hole, the tip of the drain pipe is arranged in the casing. By facing the inside of the collected recovery tank or guiding the tip of the drain pipe extended to the outside into the tank installed outside, so-called leakage-free recovery of the hydraulic oil becomes possible.

According to the present invention, the turntable is set so as to rotate while holding the hydraulic shock absorber in an inclined state. The centrifugal force generated by the rotation can be effectively used to enable the complete discharge of the hydraulic oil.

At this time, if the turntable is set so as to be able to hold a plurality of hydraulic shock absorbers at the same time, the operation of collecting the hydraulic oil can be performed efficiently.

Further, according to the present invention, the drilling means is held in the casing, and the drilling means is provided with a hydraulic oil discharge hole in the cylinder body which is the lower end side member of the hydraulic shock absorber held on the rotary table. When the hydraulic shock absorber is set to be drilled, it is possible to drill a predetermined discharge hole after setting the hydraulic shock absorber on the turntable in the casing. Even if you have
Hydraulic oil can be recovered while permitting ejection of the hydraulic oil due to the gas pressure.

As a result, according to the present invention, when extracting hydraulic oil from the hydraulic shock absorber to be discarded, the hydraulic oil can be collected without causing peripheral oil stains due to scattering of the hydraulic oil. This is, of course, ideal for achieving the intended purpose without the need for extra work such as pumping.
