Abstract

PROBLEM TO BE SOLVED: To raise a parking pallet mannually by a method wherein one end side of the parking pallet is raised by a specified level by means of a first support elevating means, then raising the other end by a specified level by means of second support elevating means, and repeating the steps. SOLUTION: When oil is fed from a hydraulic pump 29 with operation of a handle 22, it passes through a pump 30f from a port 30b of a pilot changeover valve 30 and flows into one end of an intermediate cylinder 35 to make a piston 35a push out oil at the other end side for elongating a hydraulic cylinder 3, thereby raising a parking pallet on the side of a cylinder 3. Then, when the piston 35a moves to the other end side, the oil of pump 29 passes through a port 30d from the port 30b to flow into one end of the intermediate cylinder 34, thereby elongating a hydraulic cylinder 2 for elevating the parking pallet on the cylinder 2 side. By repeating the steps the side end of the parking pallet is raised gradually, the load applied in raising the parking pallet can be reduced, thereby enabling raising the pallet mannually.

The other end of the support beam 12 is connected to the nearest corner of the parking pallet 4 so as to be rotatable around the axis.

For this reason, the parking pallet 4 is constructed such that only the hydraulic cylinder 2 is extended,
In other words, the vehicle can be raised so as to raise only the height position on one end side (for example, the front side) in the vehicle entrance / exit direction,
By extending only the hydraulic cylinder 3, it is possible to ascend so as to raise only the height position on the hydraulic cylinder 3 side, that is, the other end side (for example, the rear side) in the vehicle entrance / exit direction.

That is, in the above-described embodiment, the end portions in the width direction of the parking pallets 4 are alternately raised. In the present embodiment, the end portions of the parking pallets 4 in the vehicle entrance / exit direction. Was raised alternately.

As shown in FIGS. 7 and 8, one end of a wire 13 is connected and fixed to the upper part of the hydraulic cylinder 2. The other end of the wire 13 is connected to one end of a tension coil spring 15. The other end of the tension coil spring 15 is connected and fixed to a support fence 4 a of the parking pallet 4. The support fence 4 a has a rounded upper end, and
3 can be guided for sliding movement.
On the other hand, one end of a wire 14 is connected and fixed to the upper part of the hydraulic cylinder 3. The other end of the wire 14 is connected to one end of a tension coil spring 16. Extension coil spring 16
Is connected and fixed to a support fence 4b of the parking pallet 4. The support fence 4b has a rounded upper end so that the wire 14 can be slid and guided. I have.

That is, when only the hydraulic cylinder 2 is extended, the extension coil spring 15 is
By pulling “a” toward the hydraulic cylinder 2, it is possible to prevent the space between the support beam 11 and the support fence 4 a of the parking pallet 4 from becoming too large, and to bear a part of the weight on the parking pallet 4, and to pull The coil spring 16 pulls the support fence 4b of the parking pallet 4 toward the hydraulic cylinder 3 when only the hydraulic cylinder 3 is extended, so that the space between the support beam 12 and the support fence 4b of the parking pallet 4 is too large. This prevents the parking pallet 4 from being partly occupied.

Therefore, according to such a parking device, the hydraulic unit 2 is provided in the same manner as in the above-described embodiment.
By operating the hydraulic cylinders 2 and 3 by operating 0, the parking pallet 4 can be raised manually, and the same effect as in the above-described embodiment can be obtained.
