Description

Technology Field

[0001] The present invention relates to a mechanical parking facility, and more specifically, to a stopper system for preventing safety accidents such as vehicle damage by ensuring that a stable stopping state is maintained for the wheels during the movement of a cart moving trolley for parking a vehicle in a hangar. 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, there was a problem where vehicle movement occurred during sudden braking of the bogie because there was no stable stopping function for the vehicle wheels during the process of moving the vehicle through the bogie. Prior art literature

[0010] The present invention is proposed to improve upon the problems of the aforementioned prior art, and aims to prevent safety accidents by ensuring that a stable stopping state is maintained for the vehicle wheels during the process of moving the bogie. means of solving the problem

[0012] The present invention for achieving the above objective comprises a hangar for storing vehicles and a movable trolley for moving vehicles to the hangar, wherein the hangar and the movable trolley are each equipped with a conveyor, and wherein the movable trolley is characterized by having two pairs of wheel fixing members that are driven in mutually opposing directions by hydraulic cylinder driving on both sides to prevent movement of the vehicle wheels.

[0013] In addition, each of the above wheel fixing members is configured such that the front end of the first movable member is rotatably connected to both sides by a hinge pin, and the second movable member and the support member are respectively rotatably connected to the rear end of the first movable member on both sides, and a driving gear that meshes with each other is configured at the rear end of the second movable member, and the rear end of the support member is rotatably connected to the main body of the movable carriage, and the driving gear is characterized by being driven to rotate within a certain angle range by driving a hydraulic cylinder. Effects of the invention

[0015] The parking facility of the present invention has the effect of preventing vehicle damage or safety accidents during the parking process, as the movement of the vehicle's wheels can be stably restricted during the process of moving the parked vehicle by the movable cart.

[0016] In particular, due to an asymmetrical structure in which the wheel holder can achieve a variable tilt state depending on the alignment position of the vehicle wheels, the tilt is automatically adjusted according to the wheel alignment position, providing the advantage of mitigating shock.

Specific details for implementing the invention

[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 a stopper system for a mechanical parking facility according to one embodiment of the present invention is as follows through FIGS. 1 to 10.

[0023] The mechanical parking facility in this embodiment is configured with a hangar (10) in which a parked vehicle is stored, and a movable carriage (20) that moves horizontally along a rail (22) to move the vehicle to the hangar (10). The hangar (10) and the movable carriage (20) are each equipped with a conveyor (11, 21) that drives in one direction or in reverse direction to move the vehicle, thus forming a conventional configuration.

[0024] At this time, the movable carriage (20) in the present invention is configured such that two pairs of wheel fixing brackets (30) are driven in mutually opposing directions by hydraulic cylinders (40) to prevent movement of the vehicle wheels (T).

[0025] In particular, each of the above wheel fixing members (30) is configured such that the front end of the first movable member (31) is rotatably connected to both sides by a hinge pin, and the second movable member (32) and the support member (33) are each rotatably connected to the rear end of the first movable member (31) on both sides, and a driving gear (32a) that meshes with each other is configured at the rear end of the second movable member (32), and the rear end of the support member (33) is rotatably connected to the main body of the movable carriage (20), and the driving gear (32a) is driven to rotate within a certain angle range according to the driving of the hydraulic cylinder (40).

[0026] In addition, a movable bracket (34) is rotatably connected to the front end of the rod shaft of the hydraulic cylinder (40), and the movable bracket (34) is integrally connected to rotate coaxially with the drive gear (32a).

[0027] That is, as the cylinder rod of the hydraulic cylinder (40) is driven forward and backward, the drive gear (32a) connected to the movable bracket (34) rotates within a certain angle range relative to the gear shaft, thereby enabling the rotation of the second movable unit (32) linked to the gear shaft.

[0028] Meanwhile, it can be seen that the front end of the auxiliary movable member (35) is rotatably connected to the middle of the first movable member (31) on the one side, and the rear end of the auxiliary movable member (35) is rotatably configured to receive rotational force through the driving gear (32a).

[0029] In this embodiment, the movable carriage (20) is configured with devices such as a driving motor for horizontal travel and a driving motor for driving the carriage conveyor (21). Since this configuration is a known technology, a more detailed description of the configuration and operation is omitted.

[0030] Let us examine the effects of the operation of the stopper system of the present invention, which has such a configuration.

[0031] The stopper system of the present invention is installed on a moving cart of a mechanical parking facility and performs the function of restricting the movement of the front or rear wheels during the movement process for entering or exiting a vehicle.

[0032] That is, when the vehicle is positioned on the upper part of the movable trolley (20) by driving the trolley conveyor (21), the stopper system of the present invention is activated to restrict the movement of the wheel (T) of the present invention, and at this time, the movable bracket (34) rotates the drive gear (32a) by driving the hydraulic cylinder (40).

[0033] Accordingly, the driven gear (35a) on the opposite side rotates together, and the second movable member (32) and auxiliary movable member (35) on both sides rotate respectively around the gear axis, and the first movable member (31) rotates simultaneously, and the wheel fixing member (30) moves in a direction that moves closer to each other as shown in FIGS. 2 and 3, thereby creating a state where it holds the wheel (T) of the vehicle.

[0034] At this time, since the auxiliary operating unit (35) has an asymmetric connection configuration with an additional support member (33), the wheel fixing unit (30) may be in a tilted state as shown in FIG. 11.

[0035] Accordingly, when the wheels of the vehicle are not aligned in a straight line on the upper surface of the movable carriage (20), the tilt can be varied according to the alignment position of the wheels, so that the wheels on both sides of the vehicle can be supported more stably in any situation.

[0036] Afterwards, when the movement of the movable trolley (20) is completed and the trolley conveyor (21) is to be driven to move the vehicle to the hangar side or the exit side, the hydraulic cylinder (40) is driven, and as shown in FIGS. 4 and 5, the wheel fixing bracket (30) is moved back to its original position according to the operation of the stopper system, so that the vehicle can be moved safely.

[0037] Therefore, the parking facility of the present invention exhibits the effect of preventing vehicle damage or safety accidents during the parking process, as the movement of the vehicle wheels can be stably restricted during the process of moving the parked vehicle by the movable cart.

[0038] In particular, due to an asymmetrical structure in which the wheel holder can achieve a variable tilt state depending on the alignment position of the vehicle wheels, the tilt is automatically adjusted according to the wheel alignment position, providing the advantage of mitigating shock.

[0040] Meanwhile, FIGS. 12 and 13 show a configuration according to another embodiment of the present invention, wherein a vibration absorption layer (30a) is formed as a thin film coating on the surface of the wheel holder (30) to increase friction with the vehicle wheel (T) and absorb vibration generation, and a contact brush (30b) is provided on the bottom surface of the wheel holder (30) to remove foreign substances through contact with the surface of the conveyor (21) during forward and backward movement.

[0041] At this time, the vibration absorbing layer (30a) preferably has a mixed composition in the ratio of polydimethylsiloxane 5-20 wt%, silicone resin 15-40 wt%, NBR (Acrylonitrile Butadiene Rubber) powder 5-20 wt%, dibutyl phthalate 1-10 wt%, trioctylamine 10-20 wt%, butylated hydroxytoluene 1-10 wt%, methylchloroisothiazolinone 10-30 wt%, molybdenum powder 1-10 wt%, and behentrimonium chloride 1-10 wt%.

[0042] With this configuration, automatic surface cleaning and removal of foreign matter can be achieved through contact with the conveyor (21) during the forward and backward movement of the wheel holder (30) due to the configuration of the contact brush (30b).

[0043] In addition, since the vibration absorption layer (30a) is formed on the surface of the wheel holder (30), a stable support state is maintained in contact with the vehicle wheel during the stopper operation process, and damage to the holder and wheel is prevented due to the cushioning function.

[0044] In particular, since the vibration absorption layer (30a) 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 wheel holder (30) during the formation of the vibration absorption layer (30a) 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 vibration absorption layer (30a), and the molybdenum powder and behentrimonium chloride each increase the bonding strength between the mixed materials and exhibit an effect of improving coating density.

[0046] And, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the stopper system structure of the present invention can be implemented with various modifications by those skilled in the art.

[0047] 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
