Description

Technical Field

[0001] The present invention belongs to the technical field of vertical underground garages, and particularly relates to a working method of a multi-way circulating elevator system in a vertical garage based on a rotary platform. Background Art

[0002] How to provide enough parking spaces in a limited space has been a problem that everyone has 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. It is necessary to set up other types of elevator systems in the vertical underground garage to solve the problems of large depth and large vehicle flow.

[0004] Currently, there are also some circulating elevator systems emerging. There are multiple sets of elevators arranged on the entire circulation loop. However, for the docking of a single elevator car, the entire circulation loop needs 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 working method of a multi-way circulating elevator system in a vertical garage based on a rotary platform according to the deficiencies of the above-mentioned prior art. This working method realizes that there are parking floor entrances and exits in multiple directions within the parking floor by setting up a multi-way circulating elevator system in the central area of the segment shaft, improving the overall operation efficiency; realizes rotating the vehicles to be transported in front of the corresponding circulating elevator during peak periods through setting up a rotatable waiting platform on the part of the top floor of the garage above the ground for dredging; 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 moving the vehicle transfer chassis and the vehicle onto the translatable extraction car platform or taking them out from the translatable extraction car platform.

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

[0007] A working method of a multi-way circulating elevator system in a vertical garage based on a rotary platform, the working method comprising the following steps:

[0008] S1: Construct a vertical garage, including a segment shaft, floor slabs, a multi-loop elevator system, and a rotatable waiting platform. The segment shaft is composed of assembled caisson segments. The floor slabs are arranged from top to bottom in sequence to divide the segment shaft into several parking floors in the vertical direction. Through holes are opened in the central areas of the floor slabs to form an elevator shaft in the central area of the segment shaft. The multi-loop elevator system is arranged in the elevator shaft;

[0009] The multi-loop elevator system is composed of four groups of circulating elevators. The four groups of circulating elevators are sequentially lapped to form a quadrilateral structure;

[0010] The rotatable waiting platform is arranged on the ground around the top layer of the segment shaft, including an inner rotating platform and an outer ring road. The inner rotating platform rotates around the segment shaft. Four groups of garage entrances and exits corresponding to the four groups of circulating elevators are arranged on the top layer of the segment shaft on the ground. Each group of garage entrances and exits includes a garage entrance and a garage exit. Corresponding translational extraction vehicle platforms are arranged at both the garage entrance and the garage exit and are located on the inner rotating platform. Among them, 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 a plurality of vertical bars perpendicularly welded to the cross bar. The vertical bars are spaced apart from each other and the gap is larger than the diameter of the load-bearing bar;

[0011] S2: The outer ring road is connected to the public road on the ground. An inner lane and an outer lane are arranged on the outer ring road. Vehicles drive into the outer lane of the outer ring road through the public road, change lanes to the inner lane, and stop after corresponding to the position of the translational extraction vehicle platform in the idle state on the inner rotating platform. The vehicle is carried onto the idle translational extraction vehicle platform by a vehicle transportation chassis;

[0012] S3: Query the idle circulating elevator in the multi-loop elevator system, control the inner rotating platform to rotate until the translational extraction vehicle platform is aligned with the corresponding circulating elevator, and wait for the open car on the circulating elevator to pick up the vehicle;

[0013] Each set of the circulating elevators includes two sets of sprockets, a crawler chain, a guiding mechanism, and a number of open carriages. The two sets of sprockets are respectively arranged at the top and bottom of the segment shaft. The crawler chain is fitted onto the two sprockets and driven by the sprockets to rotate in a cycle. The open carriages are fixedly spaced on the crawler chain. The open carriage includes a vertical base plate and a number of load-bearing rods horizontally welded to the bottom of the front of the vertical base plate. The load-bearing rods are distributed at intervals to form a vehicle-carrying platform. The guiding mechanism is arranged on the back of the vertical base plate to guide the open carriage so that it always maintains a vertical state.

[0014] S4: Control the grid platform of the translational extraction vehicle platform on the inner ring rotating platform to translate outwards to the movement path of the open carriage. The vehicle-carrying platform of the open carriage in the ascending movement state and without load passes through the gaps 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 and 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.

[0015] S5: On the ground of each parking layer, there are the same number of entrances and exits as the number of circulating elevators in each set. Each set of entrances and exits includes a parking layer entrance and a parking layer exit. The parking layer entrance is correspondingly arranged on the side where the crawler chain drives downward, and the parking layer exit is correspondingly arranged on the side where the crawler chain drives upward. Both the parking layer entrance and the parking layer exit are provided with the translational extraction vehicle platform.

[0016] After the open carriage rotates around the sprocket to the descending channel, according to the required parking layer specified by the algorithm, before the open carriage is about to descend to the corresponding parking layer, control the grid platform of the translational extraction vehicle platform at the corresponding parking layer entrance to quickly translate outwards to the descending path of the open carriage. The vehicle-carrying platform of the open carriage in the descending movement state passes through the gaps of the grid platform, and makes the vehicle transfer chassis and the vehicle on it seat on the grid platform. Then control the grid platform to retract to the ground of the parking layer, and control the vehicle transfer chassis to drive off the translational extraction vehicle platform and automatically park in the empty parking space of this parking layer.

[0017] When the user needs to pick up the vehicle, control the vehicle transfer chassis to move under the chassis of the corresponding vehicle and lift it, carry the vehicle to the exit of this parking layer, and drive it onto the translational extraction vehicle platform at the exit of this parking layer.

[0018] When the empty open car rises close to the parking floor, control the grille 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 passes through the gaps of the grille platform, and synchronously transfers the vehicle transport 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 idle translational extraction vehicle platform on the inner ring rotating platform to rotate to the position corresponding to the circulating elevator carrying the vehicle, and control the grille platform of the translational extraction vehicle platform on the inner ring rotating platform to extend outward to the descending channel of the open car. Use the same method as in step S5 to enable the translational extraction vehicle platform to extract the vehicle and the vehicle transport chassis on the open car. Then control the grille platform to retract onto the inner ring rotating platform. The vehicle transport chassis transports the vehicle to the inner lane on the outer ring circular road and then descends to disengage from the vehicle, finally facilitating the user to pick up the car and drive away.

[0019] A number of drivable rollers are provided on both sides of the grille platform, and the rollers are driven by motors and travel on the slide rails on both sides.

[0020] The outer ring circular road is arranged along the outer edge of the inner ring rotating platform; the inner ring rotating platform includes a double-row circular track, a circular platform, and a horizontal rotation drive mechanism. The bottom of the circular platform is provided with universal traveling wheels that travel on the double-row circular track. The outer edge of the circular platform has convex teeth, and the horizontal rotation drive mechanism drives the convex teeth on the outer edge of the circular platform through meshing to drive the circular platform to rotate.

[0021] 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 combinations arranged between the two inner chain plates. The roller combination 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.

[0022] 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 of the vertical substrate 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.

[0023] 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 and fixedly provided with guiding columns. Two groups of guiding grooves are formed on the vertically arranged guiding base plate. One group of guiding grooves is used for guiding the upward movement of the open car, and the other group of guiding grooves is used for guiding the downward movement of the open car. Each guiding groove includes a vertically centered central groove and two vertical side grooves arranged on both sides of the vertically centered central groove. The vertically centered central groove is used for guiding the guiding columns at the vertical two ends of the cross guiding frame, and the vertical side grooves are 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 vertical side groove located on the outer side in each group of guiding grooves to adapt to the turning of the open car at the sprocket wheel.

[0024] Two groups of front and rear traveling wheels are arranged on the lower bottom surface of the vehicle transporting chassis, and the transverse length of the traveling wheels is greater than the transverse distance between at least two load-bearing rods.

[0025] The advantages of the present invention are as follows:

[0026] (1) By adopting a multi-loop elevator system, the loop elevators are mutually overlapped to form a quadrilateral, so that parking floor entrances and exits can be arranged in four directions of the vertical underground garage, and the parking and vehicle taking efficiency of each parking floor is improved;

[0027] (2) A rotatable waiting platform is arranged on the periphery of the top floor ground of the garage, which can effectively relieve the traffic pressure on the garage ground and quickly rotate the vehicle to be transported to the position of the loop elevator capable of transportation;

[0028] (3) By adopting a loop elevator system in the circular vertical underground garage, the vehicle transportation of multiple cars can be realized, and compared with the traditional single-car elevator system, the transportation capacity is effectively improved;

[0029] (4) The open car and the translational extraction car platform adopt an intermittent grid platform, so that the open car can pass through the grid platform gap of the translational extraction car platform during the normal rotation process, so as to transfer the vehicle transporting chassis and the vehicle to the translational extraction car platform or take them out from the translational extraction car platform. The vehicle can be parked and taken without stopping the operation of the elevator system, which greatly improves the operation efficiency of the entire vertical underground garage and greatly shortens the parking and vehicle taking time.

Detailed implementation mode

[0046] The features of the present invention and other related features are further described in detail below with reference to the accompanying drawings through embodiments for the understanding of those skilled in the same industry:

[0047] Embodiment: As Figures 1-15 shown, this embodiment specifically relates to a working method of a multi-way circulating elevator system based on a rotating platform in a vertical garage, and this working method includes the following steps:

[0048] (S1) Construct a vertical underground garage:

[0049] This vertical underground garage includes a segment shaft 1, a floor slab 2, a multi-way circulating elevator system, and a rotatable waiting platform 6.

[0050] The segment shaft 1 is circular and composed of assembled caisson segments, and is arranged in the space below the ground. The floor slabs 2 are arranged successively from top to bottom to divide the segment shaft 1 into several parking layers in the vertical direction. A square through hole is opened in the central area of each floor slab 2 to form an elevator shaft in the central area of the segment shaft 1. The multi-way circulating elevator system is arranged in the elevator shaft, and the space it occupies is generally a cubic space.

[0051] As Figure 3 and 4 shown, the multi-way circulating elevator system is composed of four groups of circulating elevators 3, and the four groups of circulating elevators 3 are successively lapped to form a quadrilateral structure. As Figures 1-15As shown in the figure, each set of circulating elevators 3 includes two sets of sprockets 31, a crawler chain 32, a guiding mechanism 33, and a number of open carriages 34. The two sets of sprockets 31 are respectively arranged at the top and bottom of the space occupied by the circulating elevator 3. The sprockets 31 are all driven by motors to rotate. The crawler chain 32 is correspondingly assembled on the two sets of sprockets 31 to form a circulating link. Driven by the sprockets 31, the crawler chain 32 can rotate circularly around the two sprockets 31. One side of the crawler chain 32 is in an upward movement, and the other side of the crawler chain 32 is in a downward movement. A number of open carriages 34 are arranged at intervals on the crawler chain 32. The back of the open carriage 34 is connected with a guiding mechanism 33. 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 with the crawler chain 32, so as to prevent the vehicle loaded on it from tipping over.

[0052] As Figures 1-15 shown, the crawler chain 32 is composed of inner chain links 3202 and outer chain links 3203 arranged alternately in sequence. The inner chain link 3202 includes two parallel inner chain plates 3204 and two sets of roller assemblies 3205 arranged between the two inner chain plates 3204. The roller assembly 3205 is composed of a sleeve and rollers sleeved outside the sleeve; the outer chain link 3203 includes two parallel outer chain plates 3206 and two sets of pin shafts 3201 arranged between the two outer chain plates 3206. The outer chain link 3203 is arranged between two adjacent inner chain links 3202. The two pin shafts 3201 in the outer chain link 3203 are respectively inserted into the sleeves of two adjacent inner chain links. At the setting position of the open carriage 34, one of the pin shafts 3201 in the outer chain link 3203 protrudes from the outer chain plate 3206, and relative rotation can occur between the pin shaft 3201 and the outer chain plate 3206. The back of the vertical base plate 3401 in the open carriage 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 chain plate and is fixedly connected to the guiding mechanism 33.

[0053] As Figure 10 、 11 、13 shown, the open carriage 34 includes a vertical base plate 3401 and a number of load-bearing rods 3402 horizontally welded to the bottom of the front of the vertical base plate 3401. The load-bearing rods 3402 are distributed at intervals, forming 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 stops 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 and fixing are carried out.

[0054] As Figures 1-15As shown in the figure, the guiding mechanism 33 is arranged on the back of the vertical substrate 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 substrate 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 12 shown, the guiding substrate 3301 is arranged vertically and is composed of two combined substrates, namely a large substrate and another smaller substrate attached thereto. Two groups of symmetric guiding grooves are integrally arranged on the guiding substrate 3301. One group of guiding grooves is used to guide the upward movement of the open car 34, and the other group of guiding grooves is used to guide the downward movement of the open car 34. That is, the two groups of guiding grooves are responsible for the entire circular rotation movement of the track chain 32 and the open car 34 thereon. Each group 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 vertically centered central groove 3304. The vertically centered central groove 3304 is used to guide the guiding columns at the vertical two ends of the cross guiding frame 3305, and the outer vertical side grooves 3302 and the inner vertical side grooves 3303 are respectively used to guide the guiding columns at the horizontal two 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 vertically centered central groove 3304 are opened on the guiding substrate 3301 and their depths reach the thicknesses of its two substrates. The inner vertical side groove 3303 and the vertically centered 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 combined form of a linear shape + a top arc shape.

[0055] As Figure 1 , 2 As shown in Figures 10, 11, and 12, the movement track of the cross guiding frame 3305 behind the open car 34 is described as follows:

[0056] (a) When the open car 34 moves in a purely vertical direction between the two sprockets 31, the guiding columns at the vertical two ends of the cross guiding frame 3305 move along the vertically centered central groove 3304, and the guiding columns at the horizontal two ends of the cross guiding frame 3305 respectively move along the tracks of the outer vertical side groove 3302 and the inner vertical side groove 3303.

[0057] (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 guide columns at the vertical ends of the cross guide frame 3305 gradually disengage from the vertical central groove 3304, and the guide columns at the inner ends of the cross guide frame 3305 in the transverse direction also gradually disengage from the inner vertical side groove 3303. However, the guide columns at the outer ends of the cross guide frame 3305 in the transverse direction always move around the outer vertical side groove 3302.

[0058] (c)After the open car 34 moves to the highest position above the sprocket 31, the guide columns that were originally on the inner side in the transverse direction of the cross guide frame 3305 become the guide columns on the outer side and enter the outer vertical side groove 3302 of another group for guiding. Thus, the guide columns at the vertical ends of the cross guide frame 3305 gradually enter the vertical central groove 3304 of another group, and the guide columns that were originally on the outer side in the transverse direction of the cross guide frame 3305 enter the inner vertical side groove 3303 of another group.

[0059] (d)Based on steps a - c, the open car 34 makes a cyclic rotational movement on the caterpillar chain 32.

[0060] As Figures 1-15 shown, the rotatable waiting platform 6 is arranged on the peripheral ground at the top layer of the segment shaft 1. Specifically, it is arranged on the periphery of the multi - loop elevator system. The rotatable waiting platform 6 includes an inner - ring rotating platform 61 and an outer - ring circular road 62. The inner - ring rotating platform 61 rotates around the top of the multi - loop elevator system, and the outer - ring circular road 62 is arranged on the outer ring of the inner - ring rotating platform 61 and is in contact with each other, facilitating vehicles to drive from the outer - ring circular road 62 onto the inner - ring rotating platform 61. As Figure 4 、 5 、6 shown, the inner - ring rotating platform 61 includes a double - row circular track 613, an annular platform 615, and a horizontal rotation drive mechanism 614. The bottom of the annular platform 615 is provided with universal running wheels 612 that run on the double - row circular track 613. The outer edge of the annular platform 615 has convex teeth 611. The horizontal rotation drive mechanism 614 drives the convex teeth 611 at the outer edge of the annular platform 615 through meshing to drive the annular platform 615 to rotate. Among them, the horizontal rotation drive mechanism 614 includes a motor and a small gear key - connected to the output shaft of the motor. This small gear meshes with the convex teeth 611 of the annular platform 615 to achieve meshing transmission. At the position where the outer - ring circular road 62 is in contact with the inner - ring rotating platform 61, a notch is provided for installing the horizontal rotation drive mechanism 614.

[0061] As Figures 1-15As shown in the figure, four groups of garage entrances and exits are provided on the top layer of the segment shaft 1 (i.e., the top of the multi-loop elevator system). Each group of garage entrances and exits corresponds to four groups of loop elevators 3 respectively. Each group of garage entrances and exits includes a garage entrance and a garage exit. A translational extraction vehicle platform 4 is provided at the position of each garage entrance and garage exit. That is, two translational extraction vehicle platforms 4 are arranged correspondingly on each side of the multi-loop elevator system. The translational extraction vehicle platform 4 is arranged on the inner ring rotating platform 61. The translational extraction vehicle platform 4 includes a grid platform 41 and slide rails 42 arranged on both sides of the grid platform 41. The grid platform 41 includes a cross bar 4102 at the rear end and a number of longitudinal bars 4101 vertically welded to the cross bar 4102. The longitudinal bars 4101 are distributed at intervals and the gap is larger than the diameter of the load-bearing bar 3402, so as to pass through without being affected during the mutual lifting movement. A number of drivable rollers are provided on both sides of the grid platform 41. The rollers are driven by a motor and run on the slide rails 42 on both sides.

[0062] In addition, as Figure 8 shown in the figure, a parking floor entrance and a parking floor exit are respectively provided in front of the loop elevator 3 on the ground of each parking floor. The parking floor entrance is correspondingly arranged in the area where the track chain 32 drives downward, and the parking floor exit is correspondingly arranged in the area where the track chain 32 drives upward; a translational extraction vehicle platform 4 is provided at both the parking floor entrance and the parking floor exit.

[0063] It should be noted that a vehicle transport chassis 5 is provided at the garage entrance. Two groups of front and rear traveling wheels 51 are provided on the lower bottom surface of the vehicle transport chassis 5. The lateral length of the traveling wheels 51 is greater than the lateral distance between at least two load-bearing bars 3402. And the vehicle transport chassis 5 can realize a small range of lifting to realize the loading and unloading of the vehicle chassis.

[0064] (S2) The outer ring circular road 62 is connected to the public road on the ground. Vehicles drive into the outer ring circular road 62 through the public road. At least two lanes are provided on the outer ring circular road 62. The outer lane is used for normal driving, and the inner lane is used for stopping and waiting for the vehicle after driving in. During the driving process of the vehicle on the outer lane of the outer ring circular road 62, the parking position is selected based on the indicator light at the garage entrance. That is, an indicator light is provided at the garage entrance. The indicator light will prompt whether the translational extraction vehicle platform 4 at the garage entrance is in an idle state. If the indicator light prompts that the translational extraction vehicle platform 4 at the garage entrance is idle, the vehicle changes lanes to the inner lane of the outer ring circular road 62 and stops at the position corresponding to the idle translational extraction vehicle platform 4. The vehicle transport chassis 5 automatically drives under the vehicle and supports and lifts the vehicle off the ground, and transports the vehicle to the idle translational extraction vehicle platform 4 corresponding to it on the inner ring rotating platform 61.

[0065] After (S3), query for the idle loop elevator 3 in the multi-loop elevator system, and control the inner ring rotating platform 61 to rotate so that the translational extraction vehicle platform 4 carrying the vehicle can rotate to the designated position of the loop elevator 3 and wait for the open car 34 on the loop elevator 3 to pick up the vehicle.

[0066] (S4) Control the translational extraction vehicle platform 4 to translate outward from the ground to the movement path of the open car 34. The empty open car 34 on the crawler chain 32 in the upward movement state passes through the gap of the translational extraction vehicle platform 4 and lifts the vehicle transport chassis 5 off the translational extraction vehicle platform 4 to be seated on the open car 34. Then control the translational extraction vehicle platform 4 to retract to the ground and reset. At the same time, the open car 34 carrying the vehicle and the vehicle transport chassis 5 rotates around the sprocket 31 to the descending channel.

[0067] (S5) After the open car 34 rotates around the sprocket 31 to the descending channel, according to the designated parking floor by the algorithm, before the open car 34 is about to descend to the corresponding parking floor, control the grid platform 41 of the translational extraction vehicle platform 4 at the entrance of the parking floor to quickly translate outward to the descending path of the open car 34. The open car 34 in the downward movement state passes through the gap of the grid platform 41, and the vehicle transport chassis 5 and the vehicle on it are seated on the grid platform 41 of the translational extraction vehicle platform 4. Then control the translational extraction vehicle platform 4 to retract to the ground of the parking floor. Then automatically control the vehicle transport chassis 5 to drive off the translational extraction vehicle platform 4 and automatically park in the empty parking space on this parking floor.

[0068] (S6) When the user needs to pick up the vehicle, the vehicle transfer chassis 5 is controlled to move under the chassis of the corresponding vehicle to transport it to the exit of the parking layer, and then drive to the translational extraction vehicle platform 4 at the exit of the parking layer.

[0069] The beneficial effects of this embodiment are:

[0070] (1) A multi-way circulation elevator system is used. By overlapping the circulation elevators into a quadrilateral, parking floor entrances and exits can be set up in the four directions of the vertical underground garage, thereby improving the parking and retrieval efficiency of each parking floor;

[0071] (2) A rotatable waiting platform is set up on the outer periphery of the top floor of the garage, which can effectively relieve the traffic pressure on the garage floor and quickly rotate the vehicles waiting to be transported to the position where the circulating elevator can be transported;

[0072] (3) The circular vertical underground garage uses a circulating elevator system to transport multiple cars, which effectively improves the carrying capacity compared to the traditional single-car elevator system;

[0073] (4) The open car and the translational extraction vehicle platform adopt an interval grid platform, which enables the open car to pass through the grid platform gap of the translational extraction vehicle platform during normal rotation, so as to transfer the vehicle transfer chassis and the vehicle to the translational extraction vehicle platform or take it out from the translational extraction vehicle platform. The vehicle can be parked and retrieved without stopping the elevator system, which greatly improves the operating efficiency of the entire vertical underground garage and greatly shortens the parking and retrieval time.
