Description

Double parking equiptment

The present invention relates to a two-stage parking facility, and more particularly, to a two-stage parking facility that uses the rotational force of a wheel of a vehicle as a power source for operating the parking facility.

In general, the two-stage parking facilities, the upper plate is installed so as to be elevated to the lower plate is configured to be parked in two stages by seating the vehicle on the upper and lower plates respectively. However, such a conventional parking facility requires a separate power source to raise and lower the top plate, so there is a problem of high maintenance costs.

Thus, a two-stage parking facility has been developed, which is configured to raise and lower the top plate by using the rotational force of the wheel of the vehicle. However, in order for the vehicle parked on the top plate to be raised, the top plate is raised by the operation of the top plate vehicle while the driver is in the vehicle. There should be a concern that the vehicle of the top plate should fall because it should be, and there is a problem that it is cumbersome because the top plate is completely raised and then the driver has to get off the top plate and then descend from the top plate. In addition, even when a vehicle parked on the top plate is to be released, the top plate must be lowered by the operation of the top plate vehicle while the driver is in a state of the top plate vehicle, because the driver must climb to the fully elevated top plate. As a result, the vehicle may fall.

In order to solve this problem, the applicant has filed on July 28, 2001, the Korean Patent Application No. 10-2001-45742 which is named "two-stage parking equipment". This Korean Patent Application No. 10-2001-45742 was published as Korea Patent Publication No. 10-2001-82483 dated August 30, 2001.

Korean Patent Application No. 10-2001-45742 is composed of an upper frame and a lower frame each provided with a support plate, and two stages in which both sides of the upper frame and the lower frame are connected by a lifting unit which is a folding expansion and contracting device. Parking facility.

On the bottom of the lower frame, a pair of semicircular support pieces are formed at a position biased rearward from the longitudinal center of gravity thereof, slits are formed on the outside of both front ends of the upper frame, respectively, and a pair is provided on the ground in front of the upper and lower frames. Install a fixed bracket of the upper part of each of the fixed brackets to form a pair of long holes spaced from each other, the roll shaft of the roll is inserted into the pair of long holes of the pair of fixed brackets rotatably, respectively, the respective rolls Sprockets are installed on the roll shafts of the sprockets, and chains are wound around the respective sprockets, and outer gears of the pair of fixed brackets are provided with reducers connected to one of the roll shafts of the pair of rolls, and the reducers are screwed output shafts. Protruding in parallel to both sides of the lower frame, one end of the lower end of the lifting portion And a screw nut configured to move back and forth along both sides of the lower frame as the output shaft rotates while being engaged with the output shaft, and one end of the upper end of the elevating portion is slidably inserted into the slit of the upper frame. A brake is installed under the roll of the brake, and a pair of hinges are formed at the bottom of the brake in a position biased rearward from its longitudinal center of gravity to fix the hinge axis of the hinge to the fixing bracket, A pair of semi-circular grooves are formed on the upper surface of the first half, which is slightly larger than the radius of the roll. Brake pads are provided on the inner surfaces of the respective semi-circular grooves, and the braking part has an upper end of the lower half of the support plate of the lower frame. It is installed to abut.

The Korean Patent Application No. 10-2001-45742, because a pair of rolls are rotatably and brakingly mounted between a pair of fixed brackets installed on the ground in front of the upper and lower frames, the first vehicle is seated on the upper frame. In this state, the driving wheel of the second vehicle is seated on the roll, and the rotational force of the driving wheel of the second vehicle raises the lifting unit via the roll, the chain, the reducer, the screw output shaft, and the screw nut to raise the upper frame. . Therefore, since the upper frame can be lifted in the state in which the driver descends from the first vehicle seated on the upper frame, there is no fear that the vehicle may fall during the lift, and when the driver descends or leaves the upper frame completely raised during parking. The fully raised upper frame eliminates the need for the driver to climb.

However, in spite of these advantages, Korean Patent Application No. 10-2001-45742 requires that the driving wheels of the vehicle ride over a pair of rolls whose rotation is prevented by the braking of the braking unit during entry or exit of the vehicle. Since the operation of the east is made only by the weight of the upper and lower frames, there is a problem that the braking force does not overcome the rotational force of the vehicle and slips. Then, the driving wheels of the vehicle do not ride over the pair of rolls but remain between the pair of rolls. However, the weight of the upper frame may not be very heavy to increase the braking force of the brake unit.

As shown in FIGS. 7 and 8, the front end side lower end of the lifting unit 130 is slidably inserted into the slit 241 by a pair of pinch rolls 243.

Hereinafter, the operation sequence for parking two vehicles in two stages by the two-stage parking facility of the present invention will be described.

First, in FIG. 9, the projection 671 of the front stopper 67 is pushed to the rightmost side by the tip of the horizontal plate 699, and the toenail 687 of the rear stopper 68 is the second ratchet 683 from the right side. ), The front and rear stoppers 67 and 68 are spaced apart from the pivoting plate 31, so that when the first vehicle enters, the left end of the pivoting plate 31 rotates backward by the forward rotational force of the driving wheel. The left roll 35 hides below the roll through hole 21a of the wheel contacting portion 21. Accordingly, the wheel of the first vehicle, as shown in FIG. 9, is advanced over the wheel contacting portion 21 and seated on the support plate 111 of the upper frame 110.

As such, when the vehicle is seated on the upper frame 110, as shown in FIG. 10, the tip of the contact piece 125 of the upper frame 110 pushes the shaft 66 forward while pressing the circular contact portion 697. Since the rear stopper 68 is in close contact with the rear abutment plate 39 of the pivoting plate 31, the toenail 687 is released from the second ratchet 683 from the right side and the third from the right side. Since it is caught by the ratchet 683, the state in which the rear stopper 68 is in close contact with the rear contact plate 39 is maintained. At this time, when the second vehicle enters, even if the forward rotational force of the driving wheel of the second vehicle is applied to the roll 35 of the left end of the rotating plate 31, the rotating plate 31 is moved backward by the rear stopper 68. Since rotation is prevented, the state in which the left side roll 35 protrudes above the roll through-hole 21a of the wheel contact part 21 is maintained. Thus, the wheels do not cross the roll 35 between the pair of rolls 35 and rotate the roll 35 so that they do not enter any more. When entering the second vehicle, the driving wheel must be entered first. In the present invention, a front wheel drive vehicle will be described as an example.

Next, in a state where the driving wheels of the vehicle are seated between the pair of rolls 35, when the driving wheels are continuously rotated counterclockwise to rotate the rolls 35 clockwise, the rotational force of the rolls 35 is the first drive shaft. (33), through the first chain 45, the second drive shaft 37 and the bevel gear 49, as shown in Figure 11, by rotating the output shaft 51 clockwise to rotate the screw nut 151 It moves to the rear to raise the lifting unit 130.

If the screw nut 151 continues to move backward, and the lifting unit 130 fully rises, as shown in FIG. 12, a load is applied between the output shaft 51 and the screw nut 131, thereby outputting the output shaft 51. This no longer rotates clockwise, so that the roll 35 does not rotate clockwise. At the same time, the projection 699a of the horizontal plate 699 contacts the distal end of the rod 689 of the rear stopper 68 and lifts the rod 689 upwards so that the toenail 687 is the third ratchet from the right side. 683 is caught by the second ratchet 683 from the right while the shaft 66 is moved to the left by the elastic force of the coil spring 64 while being released from 683. At 39 it is spaced apart. At this time, since the horizontal plate 699 is moved to the leftmost side, the protrusion 671 of the front stopper 67 is pushed away by the horizontal plate 699, so that the front stopper 67 has its coil spring 63. By the elastic force of the close contact with the front contact plate (39).

In the state where the rear stopper 68 is spaced apart from the rear contact plate 39, the left end portion of the rotating plate 31 is rotated backward by the forward rotational force of the driving wheel of the second vehicle, as described above. The roll 35 hides below the roll through hole 21a of the wheel contacting portion 21. Accordingly, as shown in FIG. 13, the wheel of the second vehicle moves forward over the wheel contacting portion 21 and is seated on the support plate 121 of the lower frame 120. Thus, two-stage parking of the first and second vehicles is completed.

In order to take out two vehicles parked in two stages in the two-stage parking facility of the present invention, the above-described parking operation procedure may be reversed.

When the second vehicle on the support plate 121 of the lower frame 120 is reversed, as shown in FIG. 14, first, the rear wheel, which is the driven wheel, is seated between the rolls 35, and the front wheel, which is the driving wheel, is mounted on the support plate 121. As such, the rear wheels ride over the roll 35 and the front wheels rest between the pair of rolls 35. Here, the front stopper 67 is brought into close contact with the front contact plate 39 by the elastic force of the coil spring 63, and the second vehicle is connected to the roll 35 at the right end of the pivot plate 31. Even if the reverse rotational force of the driving wheels of the driving wheel 31 is prevented from rotating forward by the front stopper 67, the right roll 35 protrudes above the roll through hole 21a of the wheel contacting portion 21. State is maintained. Therefore, the wheel does not go over the roll 35 between the pair of rolls 35 and rotates the roll 35 so that the wheel no longer moves backward.

Next, when the driving wheel of the vehicle is seated between the rolls 35, if the front wheel which is the driving wheel is continuously rotated in the clockwise direction, the roll 35 rotates in the counterclockwise direction, and the rotational force of the roll 35 is the first. The screw nut 151 is moved forward by rotating the output shaft 51 counterclockwise via the driving shaft 33, the second chain 45, the second driving shaft 37, and the bevel gear 49. Lower 130.

As the screw nut 151 continues to move forward, and as shown in FIG. 15, when the lifting unit 130 is completely lowered, a load is applied between the output shaft 51 and the screw nut 151, and thus the output shaft 51 is removed. This counterclockwise rotation does not occur, and therefore, the roll 35 does not rotate counterclockwise. At this time, since the horizontal plate 699 is moved to the rightmost side, the protrusion 671 of the front stopper 67 is pushed to the rightmost side by the distal end of the horizontal plate 699, so that the front stopper 67 is rotated. Since the vehicle is spaced apart from the 31, when the second vehicle moves backward, the right end of the pivot plate 31 rotates forward by the reverse rotational force of the driving wheel so that the right roll 35 of the wheel contacting portion 21 is rotated forward. It hides below the roll through hole 21a. In this state, when the driving wheel of the second vehicle is further rotated in the clockwise direction, the wheel of the second vehicle moves backward through the wheel contacting portion 21, as shown in FIG. 15, and leaves the second vehicle. Is completed.

Next, when the first vehicle is reversed, that is, when the wheels of the first vehicle rotate in the clockwise direction, as shown in FIG. 16, the vehicle is discharged in the same manner as the second vehicle. This completes the two-stage discharging of the first and second vehicles.

It will be appreciated that the present invention can be embodied in other specific forms without departing from the spirit constituting its main features. Accordingly, the above examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the above detailed description.

According to the two-stage parking facility of the present invention described above, it is possible to transmit the rotational force of the driving wheel of the vehicle to the lifting unit while the vehicle reliably rides over a pair of rolls when the vehicle enters or exits.
