Description

Technical Field

[0001] The invention relates to the technical field of underground stereo garages, and in particular to an underground lifting type vertical circulation stereo parking device and a garage. Background Art

[0002] At present, the available land in the city is limited. The country vigorously advocates the development of underground space, and solves the parking problem by digging shafts underground and installing mechanical stereo garages. This kind of garage occupies a small area and can make full use of the corner plots of the city. It is one of the best solutions to solve the parking problem! However, the existing silo garages (a kind of mechanical stereo garage) basically use vertical lifting stereo parking equipment, which has more storage and retrieval conversion actions and low efficiency; and the equipment cost is high, which makes the cost of the entire single parking space high, limiting the development of underground silo garages.

DETAILED DESCRIPTION

[0039] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0040] This embodiment provides an underground lifting type vertical circulation three-dimensional parking equipment and garage, which is suitable for underground silo structure. Through the cyclic lifting of the vehicle loading plate by the chain-type ring conveying mechanism, it can make full use of the silo space and efficiently park and retrieve the vehicle. The structure and vehicle storage and retrieval actions are simple and the cost is low.

[0041] like Figure 1 As shown, the garage includes: an entrance hall 1, a lifting type vertical circulation three-dimensional parking device 2 and a silo body structure 3; wherein, as Figure 2-Figure 5 As shown, the lifting type vertical circulation three-dimensional parking equipment 2 includes: a steel frame structure 21, a vehicle loading plate 22, a driving mechanism 28 and a chain-type ring conveying mechanism for lifting the vehicle loading plate 22; the entrance lobby 1 includes: the lobby floor, the car entrance and exit 11 and the opening and closing type protective plate 13; the chain-type ring conveying mechanism includes: a supporting triangle plate 23, an outer guide rail 24, a circulating large chain 25, a circulating large sprocket 26 and a chain shaft guide rail 27.

[0042] For ease of explanation, the front and rear directions in this embodiment are consistent with the front and rear directions of the vehicle (i.e., the direction of the front of the vehicle is front, and the direction of the rear of the vehicle is rear), the left and right directions are consistent with the left and right directions of the vehicle, the up and down directions are consistent with the up and down directions of the vehicle, the top is located at the top, and the bottom is located at the bottom.

[0043] like Figure 1-Figure 3As shown, the silo structure 3 is located underground and is a reinforced concrete structure. It can be a prefabricated or cast-in-place structure. Its shape can be designed to be cylindrical or rectangular according to actual needs. The top side wall of the silo structure 3 is provided with a mounting support for the drive device of the opening and closing protective plate 13 to provide a supporting reaction force. The bottom or side wall of the silo structure 3 can provide a supporting embedded part for the fixed installation of the steel frame structure 21 of the lifting type vertical circulation stereo parking equipment 2.

[0044] like Figure 2 and Figure 3 As shown, the entrance and exit lobby 1 is on the ground, fixed on the top of the silo body structure 3 and can be connected to the inside of the silo body structure 3; the lobby floor is the bottom of the entrance and exit lobby 1, and the car entrance and exit 11 stands on the lobby floor, which is the entrance and exit channel for storing and retrieving cars. The car entrance and exit 11 can be two front and rear entrances to achieve straight entry and exit, or one entrance to achieve straight entry and reverse exit or reverse entry and straight exit. A parking position 12 for storing and retrieving cars is reserved in the middle of the lobby floor. When the vehicle loading plate 22 of the lifting type vertical circulation three-dimensional parking equipment 2 is lifted to the level of the lobby floor and fixed, a parking space for storing and retrieving cars is formed, which is used to park vehicles when storing and retrieving cars. An opening and closing protective plate 13 is rotatably connected to the left and right side walls of the silo body structure 3, and when the two opening and closing protective plates 13 are closed toward each other, they are flush with and fixed to the parking space for storing and retrieving cars. They are mainly used for air protection on the left and right sides when storing and retrieving cars, to ensure the safety of personnel, to widen the parking space for storing and retrieving cars, and to improve the comfort of storing and retrieving cars. When the chain-type ring conveying mechanism in the lifting-type vertical circulation three-dimensional parking equipment 2 is in circulation, the two opening and closing protective plates 13 are opened back to back to prevent blocking the operation of the chain-type ring conveying mechanism. The opening and closing protective plates 13 are driven to open and close by a driving device (which can be a hydraulic cylinder or a pneumatic cylinder, or other general driving methods) fixed on the inner wall of the silo body structure 3.

[0045] At the same time, steps are set on the lobby floor where the front and rear ends of the parking position 12 for parking and retrieval are located. When the two opening and closing protective plates 13 are closed to be flush with the parking position for parking and retrieval, the opening and closing protective plates 13 overlap on the steps on the lobby floor. The lobby floor bears the weight of the opening and closing protective plates 13 and the weight thereon (provides a supporting reaction force) and ensures that the opening and closing protective plates 13 are flush with the lobby floor when closed. A telescopic mechanism 133 is also set on the back of the end of the opening and closing protective plate 13 opposite to the parking position for parking and retrieval. When the opening and closing protective plate 13 is closed to be flush with the parking position for parking and retrieval, the telescopic mechanism 133 extends a telescopic pin 134 to fix the vehicle loading plate 22 to prevent the vehicle loading plate 22 from shaking when parking and retrieval.

[0046] like Figure 2 and Figure 3As shown, the steel frame structure 21 is fixed inside the silo body structure 3, and is the main force-bearing structure of the entire lifting type vertical circulation three-dimensional parking equipment 2. The front and rear ends of the vehicle-carrying plate 22 are supported in the track groove of the outer guide rail 24 by a lifting device. The lifting device is used to lift the vehicle-carrying plate 22, and the vehicle-carrying plate 22 is used to carry the car; specifically: Figure 7 As shown, the lifting device includes: a lifting shaft 222, a guide arm 223, a horizontal guide wheel guide arm and a horizontal guide wheel 224; each vehicle loading plate 22 is provided with a lifting shaft 222 at both ends, and the lifting shaft 222 is located below the front and rear ends of the vehicle loading plate 22 and is perpendicular to the front and rear end surfaces of the vehicle loading plate 22 and extends in a direction away from the vehicle loading plate 22, without affecting the parking space on the vehicle loading plate 22; the end of the lifting shaft 222 away from the vehicle loading plate 22 is provided with a guide arm 223 perpendicular to the lifting shaft 222 (the guide arm 223 is perpendicular to the vehicle loading plate 224). The front and rear end surfaces of the vehicle plate 22 are parallel), and the end of the guide arm 223 away from the lifting shaft 222 is provided with a horizontal guide wheel guide arm perpendicular to the guide arm 223, and the end of the horizontal guide wheel guide arm away from the guide arm 223 is integrally formed with a horizontal guide wheel 224, and the horizontal guide wheel 224 runs in the track groove of the outer guide rail 24 to ensure that the vehicle plate 22 is horizontal in any position; wherein, the direction of the track groove of the outer guide rail 24 is the running track of the horizontal guide wheel 224, to ensure that the vehicle plate 22 is always in a horizontal state.

[0047] like Figure 2-5 As shown, the vehicle loading plate 22, the supporting triangle plate 23, the outer guide rail 24, the circulating large chain 25, the circulating large sprocket 26 and the chain shaft guide rail 27 are all symmetrically arranged between the front and rear sides of the steel frame structure 21; taking the structural arrangement of the front end as an example (the structural arrangement of the front and rear ends is symmetrical), the two circulating large sprockets 26 are arranged at the upper and lower ends of the inner side of the front end of the steel frame structure 21, and are connected by the circulating large chain 25. The circulating large sprocket 26 at the upper end is the driving wheel (driven and operated by the driving mechanism 28 installed on the steel frame structure 21), and the circulating large sprocket 26 at the lower end is the driven wheel; the chain shaft guide rail 27 (equivalent to the inner guide rail) and the outer guide rail 24 are both installed on the steel frame structure 21, and each chain shaft of the circulating large chain 25 is provided with a chain shaft guide wheel on the outer side, and the chain shaft guide wheel runs in the track groove of the chain shaft guide rail 27 to ensure that the vehicle loading plate 22 runs stably along the circular track.

[0048] In this embodiment, the lifting shaft 222 is fixed to the pin of the circulating large chain 25 through the supporting triangle plate 23, so that the vehicle carrying plate 22 rotates in a circular direction along with the circulating large chain 25. Figure 7 As shown, pin holes 221 are provided on the left and right sides of the vehicle loading plate 22. Figure 8 As shown, when the vehicle loading plate 22 moves to the parking position 12 for storing and retrieving vehicles, it cooperates with the telescopic pin 134 extending from the opening and closing protection plate 13 to ensure the stability of the parking position for storing and retrieving vehicles.

[0049] In this embodiment, the supporting triangle plate 23 is an isosceles triangle plate, and a mounting hole is respectively provided at the position of the three corners. The top of the supporting triangle plate 23 is fixedly mounted on the lifting shaft 222 of the vehicle carrier plate 22 through the top mounting hole, and the bottom is fixedly mounted on two adjacent pin shafts of the circulating large chain 25 through two bottom mounting holes, thereby realizing the chain plate connection between the vehicle carrier plate 22 and the circulating large chain 25; wherein, the circulating large chain 25 is a large heavy-load chain structure, and the supporting triangle plate 23 is used instead of the outer chain plate at intervals of an even number of chain links.

[0050] In this embodiment, the spacing between adjacent vehicle loading plates 22 in the vertical direction meets the clearance height requirement for parking, and the spacing in the left and right direction ensures that adjacent vehicle loading plates 22 do not interfere with each other during the cyclic movement.

[0051] In this embodiment, two large circulating sprockets 26 on the front and rear sides of the upper end are installed on the upper end of the steel frame structure 21 through a long axis, and two large circulating sprockets 26 on the front and rear sides of the lower end are installed on the lower end of the steel frame structure 21 through a long axis. The four large circulating sprockets 26 are driven by the same driving mechanism 28 to ensure synchronous operation.

[0052] In this embodiment, the driving mechanism 28 can be a chain drive or a gear drive. The power is provided by a three-in-one reducer, which drives the gear or sprocket coaxially arranged with the circulating large sprocket 26 to operate, thereby realizing the circulating operation of the entire garage. The driving mechanism 28 can rotate forward / reverse to realize the forward / reverse rotation of the lifting-type vertical circulating three-dimensional parking equipment 2, so that when the system allocates parking spaces for storage and retrieval, it can ensure that the vehicle loading plate 22 reaches the entrance hall 1 with the shortest running trajectory.

[0053] In this embodiment, the retractable protective plate 13 is located on the left and right sides of the parking space for storing and retrieving vehicles. Figure 6 As shown, the opening and closing protective plate 13 is provided with two or more flip hinges 131 , and each flip hinge 131 is rotatably connected to the inner wall of the silo body structure 3 .

[0054] In this embodiment, Figure 6 As shown, a flip fulcrum 132 is provided at the lower end of one side of the flip hinge 131 of the opening and closing protective plate 13, which provides a supporting point for the driving device on the inner wall of the silo body structure 3 to drive the opening and closing protective plate 13 to flip.

[0055] In this embodiment, the opening and closing protection plate 13 is formed into an inclined surface at the joint position with the parking space for storing and retrieving the vehicle to prevent obstruction when opening.

[0056] The garage is electrically connected to the external control system, and the process of storing and retrieving cars is as follows:

[0057] Parking: When parking a car, the user drives the car to the entrance hall 1, the external control system recognizes that the car needs to be parked (and the vehicle license plate is recorded at the same time), the car entrance 11 opens, the user drives the car into the parking space for parking and retrieval (at this time, the vehicle is on the floor of the hall, and other structures are in the underground silo structure 3), turns off the engine and pulls the handbrake, then leaves and parks the car outside the entrance hall 1. The car entrance 11 is closed, the telescopic pin 134 in the opening and closing protection plate 13 is retracted, the opening and closing protection plate 13 is opened to the specified position, the driving mechanism 28 drives the circulating large sprocket 26 to rotate, driving the entire circulating large chain 25 to operate, thereby driving the vehicle loading plate 22 to operate along a circular track, and the vacant vehicle loading plate 22 near the parking position 12 for parking and retrieval is moved to the parking position 12 to stop, the opening and closing protection plate 13 is closed to be flush with the floor of the hall, the telescopic pin 134 extends and fixes the vehicle loading plate 22, forming a stable parking space for parking and retrieval, and the external control system stops working. If there is no vacant loading board 22 in the lifting vertical circulation three-dimensional parking device 2 after the user has completed parking, the external control system stops running after the car entrance 11 is closed, and gives an indication that the parking space is full. If there is still an empty loading board 22 in the lifting vertical circulation three-dimensional parking device 2 after the user has completed parking, before the external control system stops running, the nearest empty loading board 22 is rotated to the reserved parking position 12 in the entrance and exit lobby 1, the opening and closing protection plate 13 is closed and placed on the lobby floor, and the telescopic pin 134 is extended to fix the loading board 22, so as to prepare for the next user to quickly park the car.

[0058] Pick up the car: The user inputs the pick up command in the external control system, and the system identifies the location of the vehicle based on the license plate. If the vehicle is in the entrance and exit lobby 1, the system directly opens the car entrance and exit 11, and the user directly picks up the car and leaves. If the vehicle is on the car loading plate 22 inside the silo body structure 3, the system first controls the retractable pin 134 to retract, and the opening and closing protective plate 13 opens to a safe position; the drive mechanism 28 drives the large circulating sprocket 26 to run, and the running path is the shortest path planned by the system. The large circulating sprocket 26 drives the large circulating chain 25 to run until the car loading plate 22 where the car is to be picked up is lifted to the parking position 12 for the storage and retrieval of the car, the drive mechanism 28 stops, the opening and closing protective plate 13 closes, the retractable pin 134 extends and fixes the car loading plate 22, the car entrance and exit 11 opens, and the user drives away; if there are two entrances and exits, the car is driven out of the warehouse in the forward direction, and if there is only one entrance and exit, the car is driven out of the warehouse in reverse. After the user leaves, the car entrance and exit 11 is closed and the system stops running.

[0059] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
