However, when the lift reaches the insertion-driven copper plate 164 provided at the upper portion of the guide channel 162, the bearing 156 of the cylindrical bar is rotated as shown in FIG. 6E. 163a is slid backwards (see (A), (B), (C) in FIG. 6E). Then, as soon as the bearing 156 is avoided from the pivoting plate 163a, the restoring force of the spring 164b is increased. By the support plate 164b (see (D) of FIG. 6E), and then the lift 15 again lowers by a predetermined height, in which case the bearing 156 is rotated by the pivot plate ( It is moved along the upper inclined surface of 163a to drive the locking pin 151 to be inserted (see (E), (F), and (G) of FIG. 6E).

On the other hand, at the lower end of the lifting side in order to lift the pallet 15 to the lift 15 is lowered with the engaging pin 15 is inserted again, the locking pin must protrude, which is the protruding driving plate 163 Perform. That is, when the lift 15 lowered with the locking pin 151 inserted therein reaches the protruding driving plate 163 provided under the guide channel 162, as shown in FIG. 6F. The bearing 156 of the cylindrical bar descends while being slightly pushed to the right along the support plate 163a on which the inclined surface at a predetermined angle is formed to protrude the locking pin 15 ((H) and (I) of FIG. 6F). (J)). Then, when the lift 15 is raised again, the bearing 156 of the cylindrical bar is raised while being supported so as not to be separated along the support plate 163b ((K), (L), and (M) of FIG. 6F). Reference).

Therefore, the lift 15 of the present invention simply lifts the pallets one after another without a separate control operation simply by driving the lift 15 repeatedly.

On the other hand, the present invention has a unique structure in order to effectively operate the present invention system as often as the driving power source.

Theoretically, if you put the same weight of 1 on each end of the wire rope on the pulley, the load on the pulley will be 2, but the lifting force will be 0.

That is, in the present invention, the load applied to the lift is offset by the load splitting weight 21 fastened to the opposite chain end by using this principle to reduce the driving force.

However, as in the lifting side of the present invention, the load is loaded only when the lift is raised and the load is not loaded when the lift is lowered, or when the lift is lowered, as in the falling side of the present invention. If the load is not loaded when the lift is lifted, when the load split weights 21 are respectively provided at one end of the lift-side chain as described above, the load split weights 21 at the lift side when the lift is lowered. ), On the contrary, on the lower side, the power for lifting the load split weight 21 is required while lifting the lift. For example, if the weight on the lift at the lift side is 3 and the weight of the load split weight 21 is 2, the driving force for actually lifting may be power for lifting the weight 1.

However, the descent requires power to bring down the weight two.

Therefore, the preferred embodiment of the present invention has been adopted even more efficient in consideration of this point, it will be described in detail as follows.

One end of the chain on the lifting side is provided with a load split weight 21 having a predetermined weight, and one end of the chain on the lower side is not provided with the load split weight 21 as described above, but is simply provided at one end of the chain. It is provided with a central weight 24 to be moved in the connected state. Then, the pulleys 25a and 25b are respectively provided downward in the front upper center of the lowering side, and another pulley 25c is upwardly installed on the auxiliary frame provided at the center of the lower side.

One end is fixed to the center of the upper side of the load split weight 21 and is hung so as to be switched by the two pulleys 25a and 25b and the pulley 25c, and the other end thereof is always the central weight ( The wire rope of predetermined length fixed to the center part of the lower side of 24 is provided.

7A and 7B show an embodiment structure of the center weight 24 employed in the present invention, and FIG. 7A shows a planar structure thereof, and FIG. 7B shows a front structure. In the figure, 211 is a center weight body, 213 is a slide channel, 215 is a chain fastener, 217 is a wire rope fastener formed in the lower center, respectively, which simply serves to hold the chain and wire rope To do.

On the other hand, Figure 7c to Figure 7d is a view showing an embodiment structure of the load splitting load split weight 21 employed in the present invention, 241 is a load split weight body, 242 is a scram (cast iron powder) 243 is a slide channel, 245 is a depression, 247 is a chain lorry, and 249 is a lifting lug.

As shown in the figure, the load split weight 21 according to the present invention is a body 241, the inside of which is filled with a scrap (242) to have a predetermined weight, the lift 15 is connected Chain rings 247 are arranged on both sides of the upper end of the body 241 to be connected to the other end (outer) end of the chain 11, and attached to both sides of the body, the cross section is A channel 243 is formed to have a magnetic shape and is moved along the surface of the load split weight guide (see 22 in FIG. 2B).

In addition, the load split weight 21 is preferably formed by including the inner surface of the body 241 by a predetermined size in order to move up and down in close contact with the guide 22 without shaking.

Particularly, in the present embodiment, the load split weight 21 is formed so that the vehicle parked on the lifting side has a weight corresponding to 1/2 of the load at full load and the load when there is no vehicle. In addition to reducing power consumption required when the pallet is raised while being reciprocated up and down along 22), friction over the pulleys 25a, 245b and 25c between the load split weight 21 and the center weight 24 is achieved. Connected to the wire rope 26, which is moved without, so that the force of lifting the lower side lift and the lowering of the lifting side lift cancel the force (that is, the force of lifting the load split weight 21). By doing so, it is possible to operate smoothly with the minimum driving power, thereby reducing power consumption as much as possible.

In the lifting and lowering driving structure of the present invention as described above, in order to easily understand how much the power saving effect according to the adoption of the load split weight 21 is possible, will be described as an example.

In other words, in order to elevate three vehicles having a pure weight of 1700 kg, a power capable of bearing a torque of 530.4 kg / M is required, but (1700 kg × 3 = 5100 kg R (sprocket radius) = 0.104 MW (net weight) =). 5100kg (excluding the weight of pallet) T (torque) = 530.4kg / M)

When the load split weight 21 is employed, a lifting force capable of bearing a torque of 72.8 kg / M is required, and an energy saving effect of about 7.3 times can be obtained.

(Vehicle weight 1700kg × 3 = 5100kg Load split weight 2200kg × 2 = 4400kg R (sprocket radius) = 0.104MW (net weight) = 700kg (excluding the weight of pallet etc.) T (torque) = 72.8kg / M )

In addition, when lowering and driving, the load split weights (2200kg × 2 = 4400kg) respectively installed on the elevating side front and rear ends are gradually raised and lowered through the rope wires 26, thereby reducing energy as in the elevating driving. Will be obtained.

On the other hand, the pallet lowering device (see FIG. 2a) in the present invention is installed in the center of the upper outer surface of the lower side of the frame structure (1) and driven under the control of the control box 23, The lower and upper outer side front and rear ends of the frame structure 1 are respectively installed to rotate the sprocket 10 by the power transmitted from the motor 6 and the rear worm reducer 8 is provided. In addition, the structure for transmitting the power generated by the motor to the front and rear reducer (8) is connected to the motor drive shaft to switch the driving force of the motor 90 degrees and at the same time decelerate to a predetermined ratio to the front and rear shaft ( A shaft coupling for coupling the shaft 9 between the gear box 7 and the gear box 7 and the worm reducer 8, respectively; 12).

The front and rear warm reducers 8 have sprockets 10 for driving the chains 11, respectively, as described above, and the sprockets 10 of the front and rear warm reducers each have a predetermined length of chain. (11) is engaged to be engaged, to move the chain forward or reverse as the motor (6) is electrostatic or reversed. In addition, even if a load split weight 22 is connected to the inner end of the chain 11 provided at each of the front and rear ends to reduce power consumption required by the pallet by a predetermined height, The outer end is simply connected to the center weight 24 that serves only to hold each end of the chain 11 and the wire rope 26, the wire between the load split weight 21 and the center weight 24 Connected to the rope 26, it is installed so as to span each of the pulley (25a, 25b, 25c).

Accordingly, as the motor is driven, the sprockets of the front and rear end worm reducers, which are installed to face each other, are rotated, and the chains 11 of the front and rear ends are respectively driven, so that the lift 15 is lift guide 16. The pallet is lifted down by a predetermined height while simultaneously lifting the pallet from the front and the rear.

In particular, in this case, when the protruding driving plate (see 163 in FIG. 6D) installs the insertion driving plate (see 164 in FIG. 6C) in a proper position in the lift guide 16, the locking pin 151 is provided at a predetermined upper height. The lifting and lowering plate 163 is disposed at a proper position inside the channel so as to protrude, and the insertion driving plate 164 is disposed at a proper position so that the engaging pins which protrude at a predetermined lower height are respectively inserted into the lifting points. It is different from the case of the side.

Thus, when the lift 15 descends, one pallet is lifted and lowered along the lift guide 16 from the predetermined upper height to the predetermined lower height, when the insertion driving plate reaches the predetermined lower height. By 164, the bearings on both sides of the cylindrical bar 155 are slowly teased and finally the locking pins 151 are inserted. On the other hand, when the elevator is lifted along the lift guide 16 while the engaging pin 151 is inserted, the cylindrical bar 155 both sides by the protruding drive plate 163 when the predetermined height is reached. As the bearing is slowly lifted, the locking pin 151 is projected again. Thus, the lift 15 repeats the above operation while moving up and down along the lift guide 16 to sequentially lower the pallets by a predetermined interval.

In addition, in the parking system of the present invention, in order to facilitate the operation, the control box 23 is provided at a position that can be easily operated by the administrator or the user. A keypad is provided so as to be provided, and sensors disposed on element elements for detecting movement of the pallets, and circuits connected to the respective driving units and the keypad to control various operations according to a user's request through the keypad are provided. This will be described later in detail with reference to FIGS. 11 to 13 of the accompanying drawings.

In addition, the parking lot according to the present invention as described above is operated as shown in the operating state of Figs. 10a to 10d, briefly described as follows.

First, the lift drive motor 2 is operated to lift and lift the three pallets 17 on the lift side (see also FIG. 10A). At this time, the lifting load is canceled by the weight of the load split weight 21 so that the power consumption is small, and the lifting side lift 15 is gradually raised by a predetermined free space (see A of FIG. Returning to the interference by the insertion drive plate 163 is inserted into the engaging pin.

Then, when the lifting operation is completed, the lower slider 14 is driven so that the lowermost pallet at the uppermost end is transferred to the lowering side of the lifting side (see also 10b). Therefore, even if the insertion driving plate 163 locking pin of the elevating side lift 15 is inserted, the three pallets which are elevated will not fall because another pallet is already filled at the lowermost point at that time.

Then, the falling drive motor 6 is driven to lower the falling side pallets (see also 10c). At this point in time, as described above, the lifting side lift and the lower side lift are simultaneously lowered. That is, the lifting side lift driving force (corresponding to the force for lifting the load split weight 21) and the lower side lift for lowering for the next lifting operation is the load split weight ( By using the opposite action on the wire rope 26 interconnecting the center weight 24 and 21, the force required for the lower side lift to lift three pallets and slowly lower the load split weight 21 The load split weight 21 acts as a reaction force against the three loads applied to the lower side lift, and acts as a reaction force against the load of the lower side lift. It is to minimize the driving force required for descending.

On the other hand, the lower side lift has a locking pin inserted at an upper end of the moving area and a locking pin protruding from the lower end of the moving area.

Thus, after the lowering operation is completed, this time, the upper slider 13 is driven to transfer the uppermost pallet on the lifting side to the upper end of the lowering side (see also 10d). The pallet transfer operation in one cycle is completed.

The present invention repeats the pallet transfer operation in the manner described above, thereby smoothly circulating the vertically stacked pallets while parking a new vehicle when an empty pallet is located at the lowermost end of the descending shaft, or a vehicle to be withdrawn When the vehicle is located at the lowermost end of the descending side, the vehicle can be shipped.
