[0002]

2. Description of the Related Art Conventionally, for removing waste oil from a vehicle, for example, after a maintenance vehicle is lifted up by a lift device, a waste oil receiver having a pan and a portable waste oil tank or a dedicated oil drain machine is installed below the maintenance vehicle ( It was carried to an appropriate lower part such as an engine, a mission, a differential, etc.), a blind plug of the engine, the mission, the differential, etc. was opened and pulled out to the saucer.

However, the conventional method using the dedicated oil drain machine has the following drawbacks.

The height of the maintenance vehicle cannot be freely set. The space below the maintenance vehicle is restricted. Every time the saucer becomes full, the waste oil must be disposed of in another drum or drain port where waste oil is accumulated, so the work is difficult and the work efficiency is poor. Waste oil is scattered and stains not only the worker but also the surroundings, so that the waste oil cannot be treated cleanly.

An upper end is connected to the downstream side of the gutter 25, and a lower end is formed with a guide pipe 26 connected to the waste oil tank 11A.

Reference numeral 17A is a mounting plate having an opening / closing lid 18A through which the waste oil receiver 10A can be projected and retracted. The mounting plate 17A is integrally mounted on the movable lift 20.

Reference numeral 27 denotes a pit cover plate which is endlessly attached to both end faces of the mounting plate 17A and which is foldably connected by a large number of elongated plate pieces. At both end parts of the endless pit cover plate 27, A pair of traction chains 31 are provided which are respectively guided by a plurality of sprockets 28 and drive sprockets 30 of a drive device 29 for moving the movable lift 20. In addition, the sprocket 28 is provided on a horizontal axis extending horizontally in the pit. 32 is a movable lift 20
2 is a guide rail for guiding the traveling roller 21 of FIG.

In the above structure, for example, when removing oil from the differential gear box of a large maintenance vehicle, the drive device 29 is first driven to horizontally move the movable lift 20 to an appropriate position. Next, the operating rod 5A of the movable lift 20 is lifted, and the maintenance vehicle (suitable for a large vehicle in particular) V is lifted to an appropriate height together with other fixed or movable lifts not shown. At this time, the receiving tray 6
The rear axle housing H of the maintenance vehicle V supported by the support arm 22 of A is in a state of being offset rearward from the center point (core) of the operating rod 5A as shown in the figure.
Next, the raising / lowering rod 9A of the device 7A is freely raised to an appropriate position in the waste oil cylinder. Then, the waste oil receiver 10A faces directly below the differential gearbox of the maintenance vehicle V. When the waste oil receiver 10A is lifted by the lifting rod 9A, the flexible hose 24 follows it. Then, when the blind plug is opened, the oil in the differential gear box flows out into the waste oil receiver 10A and first flows into the gutter 25 via the flexible hose 24. Since waste oil is viscous, it easily flows when the gutter 25 is used. Then, the waste oil flowing to the downstream side of the gutter 25 is guided by the guide pipe 26 and flows into the waste oil tank 11A.

Next, the third embodiment of the present invention shown in FIGS.
Examples will be described. Since the third embodiment is a combination of the first embodiment and the second embodiment, the same parts as those of the respective embodiments are designated by the same reference numerals, and duplicated description will be omitted.

In the third embodiment, 7 is pit 1 (1

Reference numeral 12 is a waste oil guide member for guiding the waste oil flowing into the first waste oil receiver 10 to the waste oil tank 11 (11A). On the other hand, 12A is the second waste oil receiver 1
The waste oil that has flowed into OA is the waste oil tank 11 (11
It is a waste oil guide member for guiding to A).

In the above structure, when the oil is discharged from the engine, transmission, differential gearbox, etc. of the large vehicle 1, the movable lift 20 is first used.
After moving to an appropriate position, the fixed lift 2 lifts the engine side of the large vehicle, while the movable lift 20 lifts the differential side of the large vehicle through the load receiving bases 6 and 6A and the arm 22. Next, the first and second waste oil receivers 10,
Raise 10A to the optimum position. Then, when the blind plug is opened, engine and transmission oil flows into the first waste oil receiver 10, while
The oil in the differential gearbox flows into the second waste oil receiver 10A. Then, the waste oil flowing into the first and second waste oil receivers 10 and 10A is
Via a plurality of waste oil guide members 12 and 12A,
It flows into the waste oil tank 11 (11A).

[0032]

As is apparent from the above description, the present invention has the following effects. (1) For example, in a large-sized vehicle, if the waste oil is removed, the amount of the oil alone will be about 40 kg, and the weight will be considerable when combined with the waste oil receiver. The effort of carrying it to the bottom of the vehicle or cleaning it up is excessive. According to the present invention, since the waste oil cylinder device having the waste oil receiver is provided so as to face the fixed lift installed in the pit or to the movable lift that horizontally moves in the pit through the support plate, Can be significantly reduced. (2) The waste oil receiver can be quickly set to the optimum height according to the height of the fixed or movable lift. Therefore, the work is easy and the work time can be shortened, and the waste oil does not scatter. (3) By combining the lifting device for raising and lowering the vehicle and the device for the waste oil cylinder having the waste oil receiver, the height at which the worker can easily perform the maintenance work can be freely set.
