DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for a vehicle-mounted device such as an engine generator.

[0002]

2. Description of the Related Art Many special-purpose vehicles are equipped with an activating generator as a power source for operating internal special devices when the vehicle stops. In the case of the power generator, when the pressure is 5 kVA or less, a gasoline engine is predominant.

[0003]

However, since the above-mentioned conventional power generator is installed on the floor in the vehicle compartment, there is a problem that vibrations and noises are directly transmitted into the vehicle.

[0004] As described above, the starting generator generates vibration and noise during operation, and a generator with a diesel engine having a large generating capacity is particularly large. Therefore, the generator itself is provided with vibration and soundproofing measures. is there. However, even if anti-vibration and sound-proofing measures are taken, vibration and noise are transmitted to the inside of the vehicle to a considerable extent. Not
These devices may be adversely affected.

[0005] On the other hand, most power generators have wheels provided on an underframe to facilitate movement. Therefore, the power generator is mounted on a vehicle during traveling and is stopped. Sometimes it is conceivable to drop off the vehicle and place it on the ground to drive. However, the power generator is a soundproof type with a capacity of about 5 kVA, even if it has a gasoline engine,
Since it was close to 200 kg, it was difficult to manually drop it on the ground.

SUMMARY OF THE INVENTION An object of the present invention is to provide an on-vehicle device elevating device which can easily load and unload on-vehicle equipment such as an engine generator.

[0007]

In order to solve the above-mentioned problems, a first aspect of the present invention is an apparatus for elevating a vehicle-mounted device which is externally mounted under the floor of a vehicle and which loads and unloads the vehicle-mounted device while the vehicle is stopped. There is an upper frame attached to the chassis frame or the horizontal joist of the vehicle, a lower frame provided movably up and down in the upper frame, and connected to the upper frame and the lower frame. Driving means for driving the lower frame up and down, and guide means provided on the lower frame and capable of pulling out the in-vehicle equipment from the lower frame, the driving means raising the lower frame, An in-vehicle device lifting / lowering device, wherein the in-vehicle device is sandwiched and fixed between a lower frame and the upper frame.

[0008]

Embodiments of the present invention will be described below in more detail with reference to the drawings. FIG.
FIG. 1 is a perspective view showing an embodiment of a lifting device for a vehicle-mounted device according to the present invention.

The vehicle 20 to which the lifting device 30 is attached
Has a body 22 mounted on a chassis frame 21. The body 22 includes a horizontal joist 23 fixed so as to cross the chassis frame 21, a floor 24 affixed on the horizontal joist 23, an inner plate 25 provided perpendicular to the floor 24, and an inner plate 25. Is provided with an outer plate 26 such as an aluminum plate provided outside.

In this case, the power generator 10 is connected to the vehicle 20.
Is not in direct contact with the horizontal joist 23 or the floor 24, so that noise is relatively difficult to be transmitted into the room of the vehicle body 10, but vibration is
There is a possibility that the power is transmitted to the interior of the vehicle 20 via the storage frame 31 and the chassis frame 21 of the power generator 10. Therefore, in the present embodiment, the lifting device 30 is provided outside the chassis frame 21 below the floor of the vehicle 20,
The power generator 10 is stored in the storage frame 31 of the lifting device 30.

The storage frame 31 is divided into an upper framework 31A and a lower framework 31B, and the upper framework 31A is fixed to the vehicle 20 (the chassis frame 21 or the horizontal joist 23). The lower framework 31B is combined with the upper framework 31A by an outer vertical column 31a and an inner vertical column 31b so as to be vertically movable. Each framework 31A,
31B has hydraulic cylinders 32, 3 at front and rear ends.
2 are connected. The hydraulic cylinder 32 has an upper end attached to the upper framework 31A and a lower end attached to the lower framework 31B, and is arranged in at least one pair in the vertical direction. The hydraulic cylinder 32 is arranged near the center of gravity of the power generator 10 in the left-right direction. Have been.

The lower frame 31B has a cradle 31c at the bottom thereof.
Are provided with rails 33 in the left-right direction, and the wheels 12 provided on the lower surface of the main body 11 of the power generator 10 are received on the rails 33, 33 to move the power generator 10 in the left-right direction. It is possible to put in and out. The storage frame 31 has a hook 34 provided on the upper framework 31A.
A and a latch member 34B provided on the lower frame 31B and connectable to the hook 34A are provided.

Next, the operation of the lifting device of this embodiment will be described. The elevating device 30 extends the hydraulic cylinders 32, 32 to land the lower frame 31B on the ground, and puts the power generator 10 on the ground on the rails 33, 33 of the lower frame 31B.
Press. Next, the hydraulic cylinders 32, 32 are housed, the lower framework 31B is raised, and the power generator 10 is sandwiched and fixed between the upper framework 31A and the lower framework 31B. Further, for safety, the hook 3 of the upper framework 31A is used.
A latch 34B of the lower framework 31B is hung on 4A. When the power generator 10 is taken down, the operation reverse to that described above may be performed.

In the case of a soundproof unit type, the power generator 10 is provided with a battery for a starter motor and a fuel tank, and is connected to a vehicle 20 equipped with the device by an output power cable 13 from the power generator 10. Therefore, the vibration of the generator 10 is not transmitted to the vehicle 20 at all.

In order to increase the capacity of the fuel tank, a fuel tank may be provided on the vehicle 20 side.
Even in that case, the generator 10 and the vehicle 20 are merely connected by the output power cable 13 and the fuel hose 14. Further, even when the operation of the power generator 10 is performed from within the vehicle 20 using the remote controller, the number of wires for the remote controller is merely increased between the power generator 10 and the vehicle 20. Therefore, the vibration of the power generator 10 is not transmitted to the vehicle 20.

Further, since the power generator 10 is located on the ground remote from the vehicle 20, almost no noise is transmitted into the vehicle 20. In particular, when it is necessary to minimize noise such as a broadcast relay car or a medical examination car, the cable 13 and the hose 14 connecting the power generator 10 and the vehicle 20 are extended, and the power generator 10 is connected to the vehicle. If it is far away from 20 or if it is placed on an object, the noise can be almost shut off.

The elevating device 30 of this embodiment can load and unload the power generator 10 very easily. When a crane, a lift table or the like is used as a cargo handling device for lowering the power generator 10 mounted inside the vehicle 20 to the ground instead of the elevating device 30, the device becomes large and the operation becomes large. It is awkward, requires a lot of manpower, and is dangerous.

In addition, even when performing maintenance on the power generator 10 itself, the lifting / lowering device 30 is easier to handle and has much better workability.

Various modifications and changes are possible without being limited to the embodiment described above, and these are included in the equivalent scope of the present invention. For example, when a large power generation capacity is required, a plurality of elevating devices 30 may be provided, and the number of power generators 10 may be increased. In the case where the number of hydraulic cylinders is increased in series in the front-rear direction, the number of hydraulic cylinders can be reduced by integrating the upper framework and the lower framework.

Further, in this embodiment, the description has been made by taking the power generator as an example. However, the same applies to the case of a welding machine with an engine, a compressor with an engine, a blower with an engine, a water pump with an engine, a hydraulic device with an engine, and the like. It is effective. Furthermore, even if it is not equipment with an engine, even heavy equipment that needs to be taken out of the vehicle body or on the ground, various machine tools, inspection equipment, etc. In addition, the operability of taking in and taking out the equipment is remarkably improved, and its use range is extremely wide.

The elevating device according to the present invention is a vehicle used as an emergency countermeasure base or the like which is dispatched to a disaster area such as a large earthquake and the like, for example, a disaster countermeasure vehicle equipped with daily necessities such as communication equipment, toilets and kitchens. , Command vehicles, radio vehicles, large ambulances, etc. are the most suitable attachment targets. In addition, it can be suitably attached to a camper, a working vehicle equipped with various working machines, an inspection / measurement vehicle equipped with an inspection machine, a medical examination car equipped with medical equipment such as an X-ray, a broadcast relay car, and the like.
