Abstract
Description
Technology Field
[0001] The present invention relates to a mechanical parking facility, and more specifically, to a conveyor latch system of a mechanical parking facility designed to prevent the protrusion of a vehicle parked on a hangar conveyor, thereby preventing safety accidents during parking. Background Technology
[0003] Recently, while the number of vehicles has increased explosively in cities, the shortage of parking spaces has made the expansion of parking facilities a serious issue. This situation is particularly severe in large cities, especially for high-rise commercial buildings located in the densely populated downtown areas.
[0004] As a practical solution to these parking problems, mechanical parking facilities were introduced to park as many vehicles as possible in a limited space and manage them conveniently. These mechanical parking facilities secure vertical parking spaces within a part of a building or a dedicated structure, allowing vehicles to be parked using vehicle lifts.
[0005] An example of such a mechanical parking facility is a conveyor-type mechanical parking facility that transports vehicles loaded on a lift to a hangar via a conveyor.
[0006] Meanwhile, the aforementioned mechanical parking facility comprises a lift for vertically transporting vehicles, a hangar where vehicles are parked, and a trolley for horizontally moving vehicles to transport vehicles from the lift to the hangar or vehicles from the hangar to the lift, and each can horizontally transport vehicles to and from one another using a conveyor.
[0007] However, in conventional technology, vehicles stored in a hangar may experience conveyor unraveling due to earthquakes or mechanical vibrations. This phenomenon causes the stored vehicles to protrude inward into the bogie movement passage, leading to problems such as collisions with other vehicles moving on the bogie. Prior art literature

[0019] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.
[0020] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.
[0021] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.
[0022] First, the configuration of the conveyor latch system of a mechanical parking facility according to one embodiment of the present invention is as follows through FIGS. 1 to 8.
[0023] In the present embodiment, the mechanical parking facility comprises a storage room (10) in which a parked vehicle is stored, and a movable carriage (20) that moves horizontally to move the vehicle to the storage room (10). Each of the storage room (10) and the movable carriage (20) is equipped with a conveyor (11, 21). A drive gear (24) is configured on one side of a drive shaft (23) through which power is transmitted from a drive motor (not shown) configured inside to drive the conveyor (21) in the drive frame (22) of the movable carriage (20). A driven gear (14) is configured on one side of a rotation shaft (13) in the drive frame (12) of the storage room (10) corresponding to this, thereby forming a conventional structure capable of meshing with the drive gear (24).
[0024] At this time, in the present invention, a ratchet wheel (30) is integrally fixedly provided on one side of the driven shaft (13) and driven gear (14) of the hangar (10), and a stopper (40) for controlling the rotation of the ratchet wheel (30) in one direction (reverse direction) or both directions is rotatably provided on one side of the driven frame (12) by a hinge pin (41), and the driving frame (22) configured on the movable carriage (20) is configured such that selective meshing of the driving gear (24) and the driven gear (14) for power transmission is achieved by forward and backward movement in a straight direction, and the locking state of the stopper (40) can be released.
[0025] In particular, the stopper (40) has a semicircular shape that wraps around the ratchet wheel (30) in a certain section, and a locking projection (42) that can engage with the ratchet wheel (30) is formed protrudingly on the inner side of the stopper (40), and a contact surface (43) that contacts the drive frame (22) is formed as a vertical surface at the end.
[0026] Meanwhile, the drive frame (22) on the side of the movable carriage (20) is configured to enable forward and backward movement for transmitting or releasing power to the driven frame (12), and such forward and backward movement can be achieved by a drive cylinder (not shown) configured in the movable carriage (20).
[0027] At this time, it can be seen that a contact protrusion (22a) is formed protruding from the front end of the drive frame (22) to push the stopper (40) in contact with the contact surface (43) of the stopper (40).
[0028] In addition, both sides of the rotation shaft (13) of the above-mentioned driven gear (14) are connected by mutual universal joints (15) so that power can be transmitted to the drive shaft (not shown) of the hangar conveyor (11).
[0029] In the present embodiment, the movable carriage (20) is configured with devices such as a driving motor for horizontal driving, a driving motor for driving the carriage conveyor (21), and a driving means (motor or cylinder) for moving the driving frame (22) forward and backward. Since this configuration is a known technology, a more detailed description of the configuration and operation is omitted.
[0030] We will now examine the effects of the operation of the conveyor latch system of the mechanical parking facility of the present invention, which is configured as described above.
[0031] The latch system of the present invention is installed on the hangar side of a mechanical parking facility and performs the function of controlling the operation of the hangar conveyor.
[0032] First, the movable carriage (20) with the vehicle seated thereon moves horizontally by the operation of the driving motor and is positioned in front of the corresponding hangar (10) where parking will take place.
[0033] That is, at this time, as shown in FIGS. 5 and 6, since the drive frame (22) is in a retracted state, it can be confirmed that the drive gear (24) and the driven gear (14) on the hangar (10) side are separated by a certain distance.
[0034] Afterwards, when the drive frame (22) is driven forward, as shown in FIGS. 7 and 8, the drive gear (24) moves forward together with the drive frame (22), and thus the drive gear (24) and the driven gear (14) are engaged.
[0035] At this time, as the drive frame (22) is driven forward, the contact protrusion (22a) comes into contact with the contact surface (43) of the stopper (40) and pushes the stopper (40), so that the stopper (40) rotates around the hinge pin (41) as an axis, and the fixing force on the ratchet wheel (30) is released, and the driven gear (14) is in a state where it can rotate in both directions.
[0036] In this state, when the bogie conveyor (21) rotates by driving the drive motor (not shown), the motor power is simultaneously transmitted to the drive shaft (23), and the rotational force of the drive gear (24) is transmitted to the driven gear (14), and this power is transmitted through the rotation shaft (13) and the universal joint (15) so that the forward rotation of the hangar conveyor (11) occurs simultaneously.
[0037] As such, it can be seen that the simultaneous rotation of the hangar conveyor (11) and the trolley conveyor (21) enables the parking vehicle moved by the movable trolley (20) to move to the hangar (10) and perform a hangar parking operation.
[0038] When this parking process is completed, the drive frame (22) is driven back to its original position, causing the drive gear (24) and the driven gear (14) to become separated, thereby releasing the transmission of the conveyor drive force.
[0039] Afterwards, the moving cart (20) moves horizontally to guide the next parked vehicle or to retrieve a vehicle parked in another hangar.
[0040] Meanwhile, in the present invention, the stopper (40) provided on the passive frame (12) on the hangar (10) side descends back to its original position by its own weight as the pressure applied by the driving frame (22) is released, and the latching action of the stopper (42) causes the ratchet wheel (30) to block rotation in one direction (reverse direction) or both directions.
[0041] It can be seen that, due to the action of the ratchet wheel (30), the reverse rotation of the hangar conveyor (11) is stably controlled, so the occurrence of a safety accident caused by the hangar conveyor (11) moving due to factors such as surrounding vibrations and the vehicle protruding into the inner side where the horizontal movement of the movable carriage (20) takes place can be prevented in advance.
[0042] Therefore, the conveyor latch system of the present invention enables the flow of the hangar conveyor to be efficiently controlled due to the interaction between the ratchet wheel and the stopper, thereby preventing safety accidents caused by the protrusion of the stored vehicle.
[0043] In particular, the stopper forms a semicircular shape that wraps around the ratchet wheel in a certain section, which facilitates opening and closing operations and offers the advantage of enabling a faster and more stable locking state setting due to its own weight.
[0045] Meanwhile, FIGS. 9 and 10 show a configuration according to another embodiment of the present invention, wherein the passive frame (12) elastically supports the stopper (40) when it is pushed by contact with the driving frame (22), and the opposing surface corresponding to the outer surface of the stopper (40) forms a curved shape, and the curved pad (50) is elastically supported by an elastic spring (51) so that the ratchet wheel (30) locking state can be quickly restored when the pressure of the driving frame (22) is released.
[0046] In addition, a shock-absorbing layer (43a) is formed as a thin film coating on the contact surface (43) of the stopper (40) to prevent noise generation due to contact with the drive frame (22) and to absorb shock.
[0047] At this time, the shock absorbing layer (43a) preferably has a mixed composition in the ratio of 5-20% by weight of polydimethylsiloxane, 15-40% by weight of silicone resin, 5-20% by weight of NBR (Acrylonitrile Butadiene Rubber) powder, 1-10% by weight of dibutyl phthalate, 10-20% by weight of trioctylamine, 1-10% by weight of butylated hydroxytoluene, 10-30% by weight of methylchloroisothiazolinone, 1-10% by weight of molybdenum powder, and 1-10% by weight of behentrimonium chloride.
[0048] When such a configuration is achieved, the downward movement of the stopper (40) that controls the ratchet wheel (30) can be performed more quickly due to the action of the curved pad (50) and the elastic spring (51), and a more stable locked state can be maintained, which is an advantage.
[0049] In addition, since the shock absorption layer (43a) is formed on the contact surface (43), noise is prevented from occurring due to contact with the contact protrusion (22a) of the drive frame (22), and damage is prevented due to the cushioning function.
[0050] In particular, since the shock absorption layer (43a) contains a polydimethylsiloxane component, it prevents the curing of the silicone resin and improves coating stability, and the NBR powder performs the function of improving elastic durability, while dibutyl phthalate and trioctylamine improve adhesion with the metal stopper (40) during the formation of the shock absorption layer (43a) and suppress the formation of voids, and butylated hydroxytoluene performs the function of improving the lubricity and flatness of the coating surface. In addition, the additionally added methylchloroisothiazolinone prevents the occurrence of deterioration of the shock absorption layer (43a), and the molybdenum powder and behentrimonium chloride each increase the bonding strength between the mixed materials and exhibit the effect of improving coating density.
[0052] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the latch system structure of the present invention can be implemented with various modifications by those skilled in the art.
[0053] However, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
