Description

Technical Field

[0001] The present invention belongs to the technical field of vertical underground garages, and particularly relates to a method for efficiently transporting automobiles by using a multi-way circulating elevator system in a vertical garage. Background Art

[0002] How to provide enough parking spaces in a limited space has been a problem that people have been working hard to solve. Therefore, vertical underground garages have emerged as the times require.

[0003] The vertical underground garage formed by vertical tunneling excavation is divided into several layers, and each layer can park cars. The car drives into the entrance of the vertical underground garage on the ground and is transported to the corresponding floor by a vertical elevator for parking. However, for such a large-depth and large-flow underground garage, the conventional vertical elevator has deficiencies in transportation efficiency and cannot solve the problem of large-flow transportation in the urban area. Other types of elevator systems need to be set up in the vertical underground garage to solve the problems of large depth and large vehicle flow.

[0004] At present, there are also some circulating elevator systems emerging. There are multiple sets of elevators arranged on the entire circulating loop. However, the docking of a single elevator car requires the entire circulating loop to stop running and wait for the docking of the single elevator car, which seriously reduces the operating efficiency of the entire circulating elevator system. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for efficiently transporting automobiles by using a multi-way circulating elevator system in a vertical garage according to the deficiencies of the above-mentioned prior art. In this method for transporting automobiles, a multi-way circulating elevator system is set in the central area of the segment shaft to realize that there are parking floor entrances and exits in multiple directions within the parking floor, improving the overall operation efficiency; and by arranging a number of open carriages that can always maintain a vertical state at intervals on the crawler chain of the circulating elevator system, the car-carrying plate on the open carriage is composed of a number of load-bearing rods distributed at intervals, and a translatable extraction car platform that can be telescoped back and forth is arranged on each parking floor. The translatable extraction car platform is composed of a grid platform. The car-carrying plate on the open carriage can pass through the gap of the grid platform of the translatable extraction car platform to realize the transfer of the vehicle moving chassis and the vehicle to the translatable extraction car platform or taking the vehicle out from the translatable extraction car platform.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0007] A method for efficiently transporting automobiles by using a multi-way circulating elevator system in a vertical garage, the method for transporting automobiles includes the following steps:

[0008] S1: Construct a vertical garage:

[0009] The vertical garage includes a segment shaft, floor slabs, and a multi-loop elevator system. The segment shaft is composed of assembled caisson segments. The floor slabs are arranged successively from top to bottom to divide the segment shaft into several parking floors in the vertical direction. The multi-loop elevator system is arranged in the segment shaft and penetrates the central area of each floor slab.

[0010] The multi-loop elevator system is composed of two sets of back-to-back symmetrically arranged loop elevators or four sets of successively lapped loop elevators. Each set of loop elevators includes two sets of sprockets, a crawler chain, a guiding mechanism, and several open carriages. The two sets of sprockets are respectively arranged at the top and bottom of the segment shaft. The crawler chain is fitted and sleeved on the two sprockets and driven by the sprockets to rotate in a loop. The open carriages are fixedly spaced on the crawler chain. The open carriage includes a vertical base plate and several load-bearing rods horizontally welded to the bottom of the front of the vertical base plate. The load-bearing rods are spaced apart to form a vehicle-carrying platform. The guiding mechanism is arranged on the back of the vertical base plate to guide the open carriage to always maintain a vertical state.

[0011] On the ground of each parking floor, there are the same number of entrances and exits as the number of loop elevators. Each set of entrances and exits includes a parking floor entrance and a parking floor exit. The parking floor entrance is correspondingly arranged on the side where the crawler chain drives downward, and the parking floor exit is correspondingly arranged on the side where the crawler chain drives upward. The parking floor entrance, the parking floor exit, the garage entrance of the vertical garage, and the garage exit are all provided with a translational extraction vehicle platform. The translational extraction vehicle platform includes a grid platform and slide rails arranged on both sides of the grid platform. The grid platform includes a cross bar at the rear end and several vertical bars vertically welded to the cross bar. The vertical bars are spaced apart and the gap is larger than the diameter of the load-bearing rod.

[0012] S2: The vehicle travels to the garage entrance on the ground. Control the vehicle transfer chassis to drive under the vehicle and lift it to transfer the vehicle to the translational extraction vehicle platform at the garage entrance.

[0013] Control the grid platform of the translational extraction vehicle platform at the garage entrance to translate outward from the ground to the movement path of the open carriage. The vehicle-carrying platform of the open carriage in the upward movement state and without load passes through the gap of the grid platform and lifts the vehicle transfer chassis off the grid platform to seat on the vehicle-carrying platform of the open carriage. Then control the grid platform to retract to the ground for reset. At the same time, the open carriage carrying the vehicle and the vehicle transfer chassis rotates around the sprocket at the top to the descending channel.

[0014] S3: After the open car has rotated around the sprocket to the descending channel, according to the required parking floor specified by the algorithm, before the open car is about to descend to the corresponding parking floor, control the grating platform of the translational extraction vehicle platform at the entrance of the corresponding parking floor to quickly translate outward onto the descending path of the open car. The car-carrying platform of the open car in the descending motion state passes through the gaps of the grating platform, and the vehicle transportation chassis and the vehicle thereon are seated on the grating platform. Then, control the grating platform to retract to the ground of the parking floor, and control the vehicle transportation chassis to drive off the translational extraction vehicle platform and automatically park in the empty parking space on this parking floor.

[0015] When the user needs to pick up the car, control the vehicle transportation chassis to move under the chassis of the corresponding vehicle and lift it, carry the vehicle to the exit of this parking floor, and drive onto the translational extraction vehicle platform at the exit of this parking floor;

[0016] When the empty open car rises close to this parking floor, control the grating platform on the translational extraction vehicle platform to translate in advance onto the rising path of the open car. The car-carrying platform of the open car in the rising motion state passes through the gaps of the grating platform, and synchronously transfer the vehicle transportation chassis and the vehicle thereon to the car-carrying platform. When the open car rises and rotates around the sprocket to the descending channel on the other side, control the grating platform of the translational extraction vehicle platform at the garage exit to extend outward onto the descending channel of the open car, and use the same method as in step S3 to enable the translational extraction vehicle platform to extract the vehicle and the vehicle transportation chassis on the open car. Then, control the grating platform to retract to the ground of the garage exit. The vehicle transportation chassis transports the vehicle to the designated pick-up position and then descends to separate from the vehicle, waiting for the user to pick up the car and drive away.

[0017] A circular road is provided around the top layer of the segment shaft on the ground. The four sides of the circular road are social roads. There are four entrances and exits connecting to the social roads on the circular road, and there are two two-way roads connecting the garage entrances and exits on the circular road; three of the four groups of entrances and exits are used as entrances, and the remaining one is used as an exit. The three entrances and exits used as entrances are respectively two directly connected to the circulating elevator and the entrance on one side of the two circulating elevators. Vehicles drive into the circular road from the social road through the aforementioned three entrances and drive into the garage entrance position through the incoming lane in the two-way road, waiting for the transportation of the vehicle transportation chassis; when the vehicle is taken out of the vertical garage, it drives into the circular road through the outgoing lane in the two-way road and exits to the social road through the exit.

[0018] A number of travelable rollers are provided on both sides of the grid bar platform, and the rollers are driven by a motor and travel on the slide rails on both sides.

[0019] The crawler chain is composed of inner chain links and outer chain links arranged alternately in sequence. The inner chain link includes two parallel inner chain plates and two sets of roller assemblies arranged between the two inner chain plates. The roller assembly is composed of a sleeve and rollers sleeved outside the sleeve; the outer chain link includes two parallel outer chain plates and two sets of pin shafts arranged between the two outer chain plates. The outer chain link is arranged between two adjacent inner chain links, and the two pin shafts in the outer chain link are respectively inserted into the sleeves of two adjacent inner chain links.

[0020] One of the pin shafts in the outer chain link protrudes from the outer chain plate, and relative rotation can occur between the pin shaft and the outer chain plate. The back surface of the vertical base plate in the open car is fixedly connected to the end of the pin shaft, and the other end of the pin shaft also protrudes from the outer chain plate and is fixedly connected to the guiding mechanism.

[0021] The guiding mechanism includes a cross guiding frame and a guiding base plate. The center of the cross guiding frame is fixedly connected to the end of the pin shaft. Four end parts of the cross guiding frame are respectively fixedly provided with guiding columns. Two sets of guiding grooves are formed on the vertically arranged guiding base plate. One set of guiding grooves is used for guiding the ascent of the open car, and the other set of guiding grooves is used for guiding the descent of the open car. The guiding groove includes a vertically centered central groove and two vertical side grooves arranged on both sides of the vertical central groove. The vertical central groove is used for guiding the guiding columns at the vertical two ends of the cross guiding frame, and the vertical side groove is used for guiding the guiding columns at the horizontal two ends of the cross guiding frame; wherein, an arc guiding groove is further provided at the top of the outer vertical side groove in each set of guiding grooves to adapt to the turning of the open car at the sprocket wheel.

[0022] Two sets of front and rear traveling wheels are provided on the lower bottom surface of the vehicle transportation chassis, and the transverse length of the traveling wheels is greater than the transverse distance between at least two load-bearing rods.

[0023] When the open car passes through the grid bar platform extending outwards, the lifting speed is controlled at 10 - 15 cm / s.

[0024] The advantages of the present invention are:

[0025] (1) Adopt a multi-loop elevator system. By setting the loop elevators back-to-back or overlapping them to form a quadrilateral, parking floor entrances and exits can be arranged in at least two directions or four directions of the vertical underground garage, improving the efficiency of parking and retrieving vehicles on each parking floor.

[0026] (2) By adopting a loop elevator system in a circular vertical underground garage, multi-carriage vehicle transportation can be achieved. Compared with the traditional single-carriage elevator system, the transportation capacity is effectively improved.

[0027] (3) With an open carriage and a translational vehicle extraction platform using an intermittent grid platform, the open carriage can pass through the gaps of the grid platform of the translational vehicle extraction platform during normal rotation, so as to transfer the vehicle transfer chassis and the vehicle onto the translational vehicle extraction platform or take them out from the translational vehicle extraction platform. The vehicle can be parked and retrieved without stopping the elevator system, greatly improving the operation efficiency of the entire vertical underground garage and significantly shortening the parking and retrieval time.

[0044] The features of the present invention and other related features are further described in detail through embodiments in conjunction with the accompanying drawings for the understanding of those skilled in the same industry:

[0045] As Figure 1-16 , the marks in the figure are respectively: segment shaft 1, floor slab 2, circulating elevator 3, sprocket 31, crawler chain 32, pin shaft 3201, inner link 3202, outer link 3203, inner link plate 3204, roller combination 3205, outer link plate 3206, guiding mechanism 33, guiding substrate 3301, outer vertical side groove 3302, inner vertical side groove 3303, vertical central groove 3304, cross guiding frame 3305, open car 34, vertical substrate 3401, load-bearing rod 3402, guardrail 3403, translation extraction vehicle platform 4, grid platform 41, longitudinal rod 4101, cross bar 4102, slide rail 42, roller 43, vehicle transfer chassis 5, traveling wheel 51, circular road 6.

[0046] Embodiment: As Figures 1-16 shown, this embodiment specifically relates to a method for efficiently transferring cars by using a multi-way circulating elevator system in a vertical garage. The method for transferring cars includes the following steps:

[0047] (S1) Constructing a vertical garage:

[0048] As Figures 1-16As shown in the figure, the vertical garage includes a segment shaft 1, floor slabs 2, and a multi-loop elevator system. The segment shaft 1 is circular and composed of segment linings assembled together, and is arranged in the space below the ground. The floor slabs 2 are sequentially arranged from top to bottom to divide the segment shaft 1 into several parking floors in the vertical direction. The multi-loop elevator system is arranged in the central area of the segment shaft 1, and the space it occupies is generally a cubic space.

[0049] As Figure 3 and Figure 4 shown, the multi-loop elevator system is composed of two or four groups of loop elevators 3. When the multi-loop elevator system is composed of two groups of loop elevators 3, the two groups of loop elevators 3 are arranged back to back as Figure 3 shown; when the multi-loop elevator system is composed of four groups of loop elevators 3, the four groups of loop elevators 3 are sequentially overlapped to form a quadrilateral structure as Figure 4 shown. As Figure 3 shown, in this embodiment, the multi-loop elevator system specifically adopts two groups of loop elevators 3 arranged back to back, and the following description will be made according to the two groups of loop elevators 3 adopted.

[0050] Each group of loop elevators 3 includes two groups of sprockets 31, a track chain 32, a guiding mechanism 33, and a number of open carriages 34. The two groups of sprockets 31 are respectively arranged at the top and bottom of the space occupied by the loop elevator 3, and the sprockets 31 are all driven by motors to rotate. The track chain 32 is correspondingly assembled on the two groups of sprockets 31 to form a loop link. Under the drive of the sprockets 31, the track chain 32 can rotate around the two sprockets 31 in a loop. One side of the track chain 32 is in an upward movement, and the other side of the track chain 32 is in a downward movement. A number of open carriages 34 are arranged at intervals on the track chain 32, and a guiding mechanism 33 is connected to the back of the open carriage 34. Through the setting of the guiding mechanism 33, it can be ensured that the open carriage 34 always maintains a vertical state during the rotation of the track chain 32, so as to prevent the vehicle loaded on it from tipping over.

[0051] As Figures 1-16As shown, the crawler chain 32 is composed of inner link sections 3202 and outer link sections 3203 which are arranged alternately in sequence. The inner link section 3202 includes two parallel inner link plates 3204 and two sets of roller assemblies 3205 arranged between the two inner link plates 3204. The roller assembly 3205 is composed of a sleeve and rollers sleeved outside the sleeve. The outer link section 3203 includes two parallel outer link plates 3206 and two sets of pin shafts 3201 arranged between the two outer link plates 3206. The outer link section 3203 is arranged between two adjacent inner link sections 3202, and the two pin shafts 3201 in the outer link section 3203 are respectively inserted into the sleeves of two adjacent inner link sections. At the installation position of the open car 34, one of the pin shafts 3201 in the outer link section 3203 protrudes from the outer link plate 3206, and relative rotation can occur between the pin shaft 3201 and the outer link plate 3206. The back surface of the vertical base plate 3401 in the open car 34 is fixedly connected to the end of the pin shaft 3201, and the other end of the pin shaft 3201 also protrudes from the outer link plate and is fixedly connected to the guiding mechanism 33.

[0052] As Figure 9 , Figure 10 , Figure 13 As shown, the open car 34 includes a vertical base plate 3401 and a number of load-bearing rods 3402 horizontally welded to the bottom of the front surface of the vertical base plate 3401. The load-bearing rods 3402 are spaced apart from each other to form a fence-like vehicle-carrying platform. When fixing the load-bearing rods 3402 to the vertical base plate 3401, sufficient bearing capacity when the vehicle is parked on it should be ensured. Therefore, slots can be preset on the vertical base plate 3401 in advance, and after inserting the load-bearing rods 3402 into the slots, welding fixation is carried out.

[0053] As Figures 1-16 As shown, the guiding mechanism 33 is arranged on the back surface of the vertical base plate 3401 and guides the open car 34 to keep it in a vertical state all the time. The guiding mechanism 33 includes a cross guiding frame 3305 and a guiding base plate 3301. Among them, the central area of the cross guiding frame 3305 is fixedly connected to the end of the pin shaft 3201, and guiding columns are respectively arranged at the four end parts of the cross guiding frame 3305. As Figure 9 and 10As shown, the guiding substrate 3301 is vertically arranged and is composed of two combined substrates, namely a large substrate and another smaller substrate attached thereto. Two sets of symmetric guiding grooves are integrally arranged on the guiding substrate 3301. One set of guiding grooves is used to guide the upward movement of the open car 34, and the other set of guiding grooves is used to guide the downward movement of the open car 34. That is, the two sets of guiding grooves are responsible for the entire circular rotation movement of the crawler chain 32 and the open car 34 thereon. Each set of guiding grooves includes a vertically centered central groove 3304 and two outer vertical side grooves 3302 and inner vertical side grooves 3303 arranged on both sides of the vertical central groove 3304. The vertical central groove 3304 is used to guide the guiding columns at both vertical ends of the cross guiding frame 3305, and the outer vertical side groove 3302 and the inner vertical side groove 3303 are respectively used to guide the guiding columns at both horizontal ends of the cross guiding frame 3305. Among them, the top of the outer vertical side groove 3302 also has an arc-shaped guiding groove to adapt to the turning of the open car 34 at the sprocket 31. The inner vertical side groove 3303 and the vertical central groove 3304 are opened on the guiding substrate 3301 and their depths reach the thickness of its two substrates. The inner vertical side groove 3303 and the vertical central groove 3304 are both linear and their lengths are between the two sprockets 31, while the outer vertical side groove 3302 is directly opened on the lower substrate, but it is in the form of a combination of a linear shape + a top arc shape.

[0054] As Figure 1 , Figure 2 , Figure 11 , Figure 12 shown, the movement trajectory of the cross guiding frame 3305 behind the open car 34 is described as follows:

[0055] (a) When the open car 34 moves in a purely vertical direction between the two sprockets 31, the guiding columns at both vertical ends of the cross guiding frame 3305 move along the vertical central groove 3304, and the guiding columns at both horizontal ends of the cross guiding frame 3305 move along the trajectories of the outer vertical side groove 3302 and the inner vertical side groove 3303 respectively.

[0056] (b) When the open car 34 moves to a position close to the sprocket 31, its movement trajectory will move in an arc around the sprocket 31. That is, the guiding columns at both vertical ends of the cross guiding frame 3305 gradually disengage from the vertical central groove 3304, and the guiding columns at the inner horizontal ends of the cross guiding frame 3305 also gradually disengage from the inner vertical side groove 3303, but the guiding columns at the outer horizontal ends of the cross guiding frame 3305 always move around the outer vertical side groove 3302.

[0057] (c) After the open car 34 moves to the highest position above the sprocket 31, the guide posts on the original inner side in the horizontal direction of the cross guide frame 3305 become the guide posts on the outer side and enter the outer vertical side grooves 3302 of the other group for guiding. Thus, the guide posts at both vertical ends of the cross guide frame 3305 gradually enter the vertical central grooves 3304 of the other group, and the guide posts on the original outer side in the horizontal direction of the cross guide frame 3305 enter the inner vertical side grooves 3303 of the other group.

[0058] (d) Based on steps a - c, the open car 34 makes a cyclic rotational movement on the crawler chain 32.

[0059] As Figures 1-16 shown, the top layer of the segment shaft 1 on the ground is the top of the two groups of circulating elevators 3 arranged symmetrically back to back. A garage entrance and a garage exit are provided on the front of each group of circulating elevators 3, and a translational extraction vehicle platform 4 is provided at both the garage entrance and the garage exit. As Figure 16 shown, a circular road 6 located within the ground area of the parking lot is provided around the top layer of the two groups of circulating elevators 3. The periphery of the circular road 6 is the social road. Entrances and exits are provided at the four peripheries of the circular road 6, and the four groups of entrances and exits are respectively connected to the social road. At the same time, two two - way roads leading to the garage entrances and exits of the two groups of circulating elevators 3 are provided on the circular road 6. Specifically, three of the four groups of entrances and exits are used as entrances (i.e., the two entrances directly connected to the circulating elevators 3 and the entrance on one side of the two circulating elevators 3), and the remaining one is used as an exit. Vehicles drive into the circular road 6 from the social road through the aforementioned three entrances and drive into the garage entrance position through the incoming lane in the two - way road, waiting for the vehicle transfer chassis 5 and the translational extraction vehicle platform 4 to carry. When the vehicle is taken out from the vertical garage, it drives into the circular road 6 through the outgoing lane in the two - way road and exits to the social road through the exit.

[0060] In addition, a parking layer entrance and a parking layer exit are respectively provided in front of the circulating elevators 3 on the ground of each parking layer. That is, as Figure 7As shown, in the case of two groups of circulating elevators 3, each parking floor is provided with two groups of parking floor entrances and parking floor exits. The parking floor entrance is arranged corresponding to the area where the crawler chain 32 is driven downward, and the parking floor exit is arranged corresponding to the area where the crawler chain 32 is driven upward; the parking floor entrance and the parking floor exit are both provided with a translational extraction vehicle platform 4. The translational extraction vehicle platform 4 includes a bar platform 41 and slide rails 42 arranged on both sides of the bar platform 41. The bar platform 41 includes a cross bar 4102 located at the rear end and a plurality of longitudinal bars 4101 vertically welded to the cross bar 4102. The longitudinal bars 4101 are spaced apart and the gap is greater than the diameter of the load-bearing rod 3402, so that they can pass through without being affected when they move up and down. A plurality of movable rollers 43 are arranged on both sides of the bar platform 41. The rollers 43 are driven by a motor and move on the slide rails 42 on both sides.

[0061] (S2) The vehicle enters the garage entrance and is transferred by the open car 34:

[0062] like Figures 1-16 As shown, according to the waiting situation for storage on the ground, the vehicle enters the garage entrance in front of the corresponding circulating elevator 3 through the circular road 6 and stops, and the vehicle transfer chassis 5 automatically drives to the bottom of the vehicle chassis and lifts it to leave the ground, and then automatically drives to the translational extraction vehicle platform 4 at the garage entrance to wait for transportation. Among them, the lower bottom surface of the vehicle transfer chassis 5 is provided with two sets of front and rear running wheels 51, and the lateral length of the running wheels 51 is greater than the lateral distance between at least two load-bearing rods 3402. And the vehicle transfer chassis 5 can achieve a small range of lifting and lowering to achieve the loading and unloading of the vehicle chassis.

[0063] The bar platform 41 of the translational extraction vehicle platform 4 is controlled to translate outward from the ground to the movement path of the open car 34. The unloaded open car 34 on the crawler chain 32 in the ascending state passes through the gap of the bar platform 41 and lifts the vehicle transfer chassis 5 off the bar platform 41 to sit on the vehicle loading platform of the open car 34. Then the bar platform 41 is controlled to retract to the ground and reset. At the same time, the open car 34 carrying the vehicle and the vehicle transfer chassis 5 rotates around the sprocket 31 to the descending channel.

[0064] It should be noted that when the open car 34 and the outwardly extended grid platform 41 pass each other, the lifting speed of the open car 34 is controlled at about 10-15 cm / s to ensure that its carrying platform can be in stable contact with the vehicle transfer chassis 5 to avoid impact damage caused by excessive speed.

[0065] (S3) The open car 34 transfers the vehicle to the designated parking floor:

[0066] After the open car 34 rotates around the sprocket 31 and reaches the descending channel, according to the required parking floor specified by the algorithm, before the open car 34 is about to descend to the corresponding parking floor, the grating platform 41 of the translational extraction car platform 4 at the entrance of the parking floor is controlled to quickly translate outward onto the descending path of the open car 34. The car-carrying platform of the open car 34 in the descending motion state passes through the gaps of the grating platform 41, and the vehicle transport chassis 5 and the vehicle thereon are seated on the grating platform 41. Then, the grating platform 41 is controlled to retract to the ground of the parking floor. After that, the vehicle transport chassis 5 is automatically controlled to drive down from the translational extraction car platform 4 and be automatically parked in the empty parking space on this parking floor.

[0067] (S4)User picks up the car:

[0068] When the user needs to pick up the car, enter their license plate number on the operation large screen at the garage exit position. The system queries the parking floor and parking space number where the vehicle is located. Then, the vehicle transport chassis 5 on this parking floor is controlled to move under the chassis of the corresponding vehicle and transport it to the exit of this parking floor, and drive onto the translational extraction car platform 4 at the exit of this parking floor. When the empty open car 34 rises close to this parking floor, the grating platform 41 of the translational extraction car platform 4 is controlled to translate in advance onto the rising path of the open car 34. The open car 34 in the rising motion state passes through the gaps of the grating platform 41, and synchronously transfers the vehicle transport chassis 5 and the vehicle thereon to the car-carrying platform of the open car 34. When the open car 34 rises and rotates around the sprocket 31 to the descending channel on the other side, the grating platform 41 at the garage exit is controlled to extend outward onto the descending channel of the open car 34. In the same way as in step S3, the translational extraction car platform 4 extracts the vehicle and the vehicle transport chassis 5 on the open car 34. Then, the grating platform 41 is controlled to retract to the ground at the garage exit. After the vehicle transport chassis 5 transports the vehicle to the designated car pick-up position, it descends and detaches from the vehicle, and finally facilitates the user to pick up the car and drive away.

[0069] The beneficial effects of this embodiment are:

[0070] (1)Adopt a multi-loop elevator system. By setting the loop elevators back-to-back or overlapping each other to form a quadrilateral, parking floor entrances and exits can be arranged in at least two directions or four directions of the vertical underground garage, improving the parking and pick-up efficiency of each parking floor;

[0071] (2)For the circular vertical underground garage, by adopting a loop elevator system, multi-carriage vehicle transportation can be realized. Compared with the traditional single-carriage elevator system, the transportation capacity is effectively improved;

[0072] (3) By adopting an intermittent grille platform for the open car and the translation extraction vehicle platform, the open car can pass through the gaps between the grille platforms of the translation extraction vehicle platform during normal rotation, so as to transfer the vehicle transportation chassis and the vehicle onto or from the translation extraction vehicle platform. In this way, the vehicle can be parked and retrieved without stopping the elevator system, which greatly improves the operation efficiency of the entire vertical underground garage and significantly shortens the parking and retrieval time.
