Description

[Detailed description of the invention] The present invention relates to a two-tiered parking device for parking cars in two levels, upper and lower. In a parking device that is engaged with a winder and raised and lowered by a winding and unwinding device, the upper stage of the vehicle is stored at a slight inclination.

The embodiment shown in the drawings will be explained below.
1 is a base fixed to the floor with anchor bolts, and a portal support 2 formed in the shape of a portal frame is attached to one end of the base.
is fixed and stands upright, and its both side members are made of channel steel, and the guide rail 5 is constituted by the groove. Reference numeral 6 denotes an elevating frame equipped with upper and lower wheels 7, 8 on both sides that engage with the guide rail 5, and at its lower end, one longitudinal end of an elevating pallet 9 configured to place a car is attached. The gate-shaped support 2 is fixed so that the angle between the line connecting the upper and lower wheels 7 and 8 and the lifting pallet 9 is 87 to 80 degrees when viewed from the side, and the lifting frame 6 and the lifting pallet 9 are fixed at an angle of 87 to 80 degrees. The pallet 9 constitutes the elevating body A. The guide rail 5 is formed in an upright groove shape and has a front edge 3 provided on the protruding side of the elevating pallet 9 and a trailing edge 4 provided on the opposite side of the protruding side of the elevating pallet 9. Bend the rear edge 4 below the engagement position between the rolling wheels 7 above the lift frame 6 and the rear edge 4, and expand only the rear edge 4 by tilting it by 3 to 10 degrees in the opposite direction to the side on which the lift pallet 9 protrudes. The groove is formed so that the sum of this angle and the angle formed by the upper and lower rollers of the lifting pallet 9 is approximately 90°. Reference numeral 10 is a joint material fixed to the opposite side of the lifting frame 6 from which the lifting pallet 9 protrudes, and is a winding and unwinding device 1 consisting of an electric chain block suspended from the top member 11 of the gate-shaped support 2.
The lower end of the traction strip 13 of No. 2 is fixed. This device is equipped with a car stop device, fall prevention device, travel restriction device,
Although it is equipped with various safety devices such as an emergency stop device, it is omitted as it is not the gist of the present invention.

Next, to explain its operation, as shown in FIG. 3, when the lifting pallet 9 is in the lowered position, the upper rolling wheels 7 of the lifting frame 6 come into contact with the front edge 3 of the lead, and the lower rolling wheels 8 touch the leading edge 3 of the lifting frame 6 after tilting. The lifting pallet 9 extends substantially horizontally in contact with the edge 4, and its tip is in contact with the floor surface. In this state, the car is moved onto the lifting pallet 9, and the winding and unwinding device 12 is driven to lift the lifting frame 6.
When the pallet is lifted, the upper and lower wheels 7 and 8 rise along the guide rail 5, the lower wheel 8 enters the vertical part of the rear edge 4, and the tip of the lifting pallet 9 lifts up as shown in Fig. 1. It will be in the stored state. In this case, since the elevating pallet 9 is inclined with respect to the horizontal line, the center of gravity G is shifted toward the elevating frame 6 by an amount a compared to when the elevating pallet 9 is horizontal, which is indicated by the phantom line in Fig. 1. As a result, the load on the front wheels of the automobile, that is, the base of the lifting pallet 9 increases, and the load on the rear wheels, that is, the lifting pallet 9 increases.
Since the load applied to the tip of the lifting pallet 9 is reduced, the bending moment applied to the beam of the lifting pallet 9 is reduced compared to when the pallet is horizontal, and the force acting on the beam is divided into a vertical component perpendicular to the beam and a horizontal component parallel to the beam. The bending moment is further reduced by being decomposed into force components.

In this embodiment, only one pair of portal supports are installed at the ends, but as in other embodiments shown in FIGS. 4 and 5, the width of the portal supports is It is also possible to expand the pallets to accommodate the lifting pallets in the gate shape, and to arrange a large number of pallets in parallel, and in this case, the same operation and effect will be achieved.

As described above, according to the present invention, since the automobile is supported at an incline when it is raised and stored, it is possible to reduce the bending moment applied to the beam of the lifting pallet when it is stored. Since the space above the lower storage car can be effectively used for storage, the height of the lift pallet can be lowered and the pallet can be made more compact.In addition, only the rear edge can be tilted in the opposite direction to the protruding side of the lift pallet to provide support. Since the base is widened and stands upright, it is stable and extremely robust, and it is also easy to manufacture.
