 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is an overall side view of a power takeoff device according to the present invention, and FIG. 2 is a front view of the same. Reference numeral (1) is two metal rolls integrally provided around an output shaft (2). (2) penetrates the center of the roll (1), and both ends of the output shaft (2) are projected from both ends of the roll (1). The output shaft (2) is fixed to the center of the roll (1) by bearings (3) fitted and fixed to both ends of the roll (1).

And, two rolls (1) are supported by a plurality of rollers (4), respectively, and laid horizontally in parallel at the same height position on the upper surface side of a machine board (5) having a square base plate shape. In this case, the bearing (mainly receiving a radial load) is used as the roller (4), and the both ends of each roll (1) are supported by two sets of rollers (4). The two rollers (4) of each set are arranged facing each other in the direction orthogonal to the output shaft (2) of the roll (1) so that the outer peripheral surface of the outer ring makes rolling contact with the same outer peripheral surface of the roll (1). The roll (1) is rotatably supported.

The bearing (7) of the central shaft (6) of each roller (4) is fixed to the upper surface of the machine base (5) with a bolt (8), and each roller (4) is rotated on the upper surface of the machine base (5). It is installed freely.

Both ends of the output shaft (2) of each roll (1) are supported by bearings (9) (mainly subject to thrust load) to a bearing stand (10) mounted on the upper surface of the machine stand (5).

After connecting one end of the output shaft (2) of one roll (1) and the input shaft of a driven machine tool (for example, a pump) by a belt transmission mechanism (12), By driving the left and right drive wheels (11) on the same drive shaft of the truck (T) and the self-propelled vehicle (T) between the rolls (1) and starting the vehicle in the same way as when running normally, The running vehicle (T) rotates with the driving wheels (11) being supported by the roll (1) while stopped on the spot. At that time, the roll (1) also comes into contact with the driving wheel (11) and rotates to rotate the output shaft (2) at the center of the roll (11). The rotation and torque of the output shaft (2) are transmitted to the input shaft of the driven machine tool by the belt transmission mechanism (12) to drive the machine tool.

Further, the rotation speed and the torque of the output shaft (2) can be easily adjusted by the accelerator adjustment and the speed change operation of the self-propelled vehicle (T), and the power suitable for the driven mechanical device can be easily obtained. It is possible.

Further, for example, the rollers (4) can be adjusted so that the distance between the rolls (1) can be adjusted to match the large-diameter drive wheels such as trucks and the small-diameter drive wheels such as passenger cars. ), And the bolt holes (not shown) for mounting the bearing (9) to the machine base (5) for the truck and passenger cars. It is preferable to provide. Further, it is preferable that each bolt hole is made a long hole so that the interval between the rolls (1) can be finely adjusted at each mounting position by the push bolt (13).

In order to reduce the slip between the drive wheel (11) and the roll (1), the surface of the roll (1) may be processed to increase the frictional force with the drive wheel (11). I like it.

Further, each roller (4) properly receives the radial load (vehicle weight of the self-propelled vehicle) applied to the roll (1) so that the roll (1) can smoothly rotate, so that the drive wheels ( It is preferable to support the roll (1) at the position where 11) is placed.

As for the rotation direction of the output shaft (2), the riding direction of the drive wheel (11) and the attachment position of the pulley of the belt transmission mechanism (12) can be appropriately selected at the left end and the right end of the output shaft (2). Can be obtained in either rotation direction.

The self-propelled vehicle (T) has a drive wheel (11) mounted on each roll (1), and a tire stopper is attached to the steering wheel, or the vehicle body is fixed to a fixed object with a wire or the like to drive the vehicle. It is preferred that the loop (11) does not come off the roll (1).

A large number of this device is stored in a warehouse (waterproof warehouse) etc. and used by transporting it to the site of use by trucks, etc., or it is buried in advance in the roads and sidewalks of towns, parks, river banks, sea revetments It can also be installed in a closed position, usually closed with a lid, and opened in the event of an earthquake.

The device may also drive a generator to provide electricity to operate lighting and various electromechanical devices.

Not only can the truck serve as a drive source, but a vinyl sheet can be stretched around the truck bed to collect water and relay it with another pump.

In the case of a self-propelled vehicle having two drive shafts, two of these devices are used side by side. It can also be used as a structure in which four rolls (1) are provided on one machine base.
