[0018] Example: Figure 1-Figure 16 As shown, this embodiment specifically relates to a method for efficiently transporting a car in a vertical garage using a multi-circulation elevator system, and the method for transporting a car includes the following steps: (S1) Construction of vertical garage: like Figure 1-Figure 16 As shown, the vertical garage includes a segment shaft 1, a floor plate 2 and a multi-circulation elevator system. The segment shaft 1 is circular and composed of caisson segments, and is arranged in the space below the ground. The floor plates 2 are arranged in sequence from top to bottom to divide the segment shaft 1 into several parking floors in the vertical direction. The multi-circulation elevator system is arranged in the central area of ​​the segment shaft 1, and the space it occupies is a cubic space as a whole.

[0019] like Figure 3 and Figure 4 As shown, the multi-way circulation elevator system is composed of two or four groups of circulation elevators 3. If the multi-way circulation elevator system is composed of two groups of circulation elevators 3, the two groups of circulation elevators 3 are as shown in FIG. Figure 3 If the multi-circulation elevator system consists of four groups of circulating elevators 3, the four groups of circulating elevators 3 are as shown in FIG. Figure 4 As shown in the figure, they are overlapped in sequence to form a quadrilateral structure. Figure 3 As shown, the multi-circulation elevator system in this embodiment specifically adopts two groups of circulation elevators 3 arranged back to back, and the following description is based on the two groups of circulation elevators 3 adopted.

[0020] Each set of circulating elevators 3 includes two sets of sprockets 31, crawler chains 32, guide mechanisms 33, and a number of open cars 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 driven to rotate by motors. The crawler chains 32 are correspondingly mounted on the two sets of sprockets 31 to form a circulating chain. Under the transmission of the sprockets 31, the crawler chains 32 can rotate around the two sprockets 31 in a circular manner. The crawler chains 32 on one side move upward, and the crawler chains 32 on the other side move downward. A number of open cars 34 are arranged at intervals on the crawler chains 32. The back of the open cars 34 is connected to the guide mechanism 33. The setting of the guide mechanism 33 can ensure that the open cars 34 always remain in a vertical state during the rotation of the crawler chains 32 to prevent the vehicles loaded thereon from overturning.

[0021] like Figure 1-Figure 16 As shown, the crawler chain 32 is composed of inner links 3202 and outer links 3203 which are arranged alternately in sequence. The inner link 3202 includes two inner link plates 3204 which are arranged in parallel and two groups of roller assemblies 3205 which are arranged between the two inner link plates 3204. The roller assembly 3205 is composed of a sleeve and a roller which is sleeved outside the sleeve. The outer link 3203 includes two outer link plates 3206 which are arranged in parallel and two groups of pins 3201 which are arranged between the two outer link plates 3206. The outer link 3203 is arranged between two adjacent inner links 3202. The two pins 3201 in the outer link 3203 are respectively inserted into the sleeves of the two adjacent inner links. At the setting position of the open car 34, one of the pins 3201 in the outer chain link 3203 protrudes from the outer link plate 3206, and the pin 3201 and the outer link plate 3206 can rotate relative to each other. The back side of the vertical base plate 3401 in the open car 34 is fixedly connected to the end of the pin 3201, and the other end of the pin 3201 also protrudes from the outer link plate and is fixedly connected to the guide mechanism 33.

[0022] like Fig. 9 , Fig.10 , Fig.13 As shown, the open car 34 includes a vertical base plate 3401 and a plurality of load-bearing rods 3402 horizontally welded to the bottom of the front side of the vertical base plate 3401. The load-bearing rods 3402 are spaced apart to form a fence-like vehicle-carrying platform. When fixing the load-bearing rods 3402 to the vertical base plate 3401, sufficient load-bearing capacity should be ensured when the vehicle is parked thereon. Therefore, slots can be preset on the vertical base plate 3401, and the load-bearing rods 3402 can be inserted into the slots and then welded and fixed.

[0023] like Figure 1-Figure 16As shown, the guide mechanism 33 is arranged on the back of the vertical base plate 3401 and guides the open car 34 to keep it in a vertical state. The guide mechanism 33 includes a cross guide frame 3305 and a guide base plate 3301. The central area of ​​the cross guide frame 3305 is fixedly connected to the end of the pin shaft 3201, and the four ends of the cross guide frame 3305 are respectively provided with guide posts. Fig. 9 and 10 As shown, the guide base plate 3301 is vertically arranged, and is composed of two base plates arranged in close contact with each other, namely a large base plate and another smaller base plate arranged in close contact with it. Two groups of mutually symmetrical guide grooves are arranged on the guide base plate 3301 as a whole, one group of guide grooves is used to guide the upward movement of the open car 34, and the other group of guide grooves is used to guide the downward movement of the open car 34, that is, the two groups of guide grooves are responsible for the entire cyclic rotation movement of the crawler chain 32 and the open car 34 thereon. Each set of guide grooves includes a centrally arranged vertical center groove 3304 and two outer vertical side grooves 3302 and inner vertical side grooves 3303 arranged on both sides of the vertical center groove 3304. The vertical center groove 3304 is used to guide the guide columns at the vertical ends of the cross guide frame 3305, and the outer vertical side grooves 3302 and the inner vertical side grooves 3303 are respectively used to guide the guide columns at the horizontal ends of the cross guide frame 3305; wherein, the top of the outer vertical side groove 3302 also has an arc guide groove to adapt to the turning of the open car 34 at the sprocket 31. The inner vertical side groove 3303 and the vertical center groove 3304 are opened on the guide substrate 3301 and their depth reaches the thickness of the two substrates. The inner vertical side groove 3303 and the vertical center groove 3304 are both linear and the length is located between the two sprockets 31, while the outer vertical side groove 3302 is directly opened on the lower substrate, but it is a combination of linear + top arc type.

[0024] like Figure 1 , Figure 2 , Fig.11 , Fig.12 As shown, the motion trajectory of the cross guide frame 3305 behind the open car 34 is described as follows: (a) When the open elevator car 34 moves in a purely vertical direction between the two sprockets 31, the guide columns at the vertical ends of the cross guide frame 3305 move along the vertical center groove 3304, and the guide columns at the horizontal ends of the cross guide frame 3305 move along the trajectories of the outer vertical side groove 3302 and the inner vertical side groove 3303 respectively.

[0025] (b) When the open elevator car 34 moves to a position close to the sprocket 31, its motion 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 center groove 3304, and the guide columns at the lateral inner ends of the cross guide frame 3305 also gradually disengage from the inner vertical side groove 3303, but the guide columns at the lateral outer ends of the cross guide frame 3305 always move around the outer vertical side groove 3302.

[0026] (c) When the open elevator car 34 moves to the highest position above the sprocket 31, the guide columns originally on the inner side of the cross guide frame 3305 become guide columns located on the outer side and enter the outer vertical side grooves 3302 of another group for guidance. As a result, the guide columns at both ends of the cross guide frame 3305 gradually enter the vertical center grooves 3304 of another group, and the guide columns originally on the outer side of the cross guide frame 3305 enter the inner vertical side grooves 3303 of another group.

[0027] (d) Based on steps ac, the open car 34 performs a circular rotation motion on the crawler chain 32 .

[0028] like Figure 1-Figure 16 As shown, the top floor of the segment shaft 1 on the ground is the top of two groups of circulating elevators 3 arranged symmetrically back to back. The front of each group of circulating elevators 3 is provided with a garage entrance and a garage exit, and a translational extraction vehicle platform 4 is provided at the garage entrance and the garage exit. Fig.16 As shown, a ring road 6 located in the ground area of ​​the parking lot is arranged on the outer periphery of the top floor of the two groups of circulating elevators 3, and the outer periphery of the ring road 6 is the social road. Entrances and exits are arranged on the four sides of the ring road 6, and the four groups of entrances and exits are respectively connected to the social roads. At the same time, two two-way roads leading to the garage entrances and exits of the two groups of circulating elevators 3 are arranged on the ring road 6. Specifically, three of the four groups of entrances and exits are used as entrances (i.e., two entrances and exits directly connected to the circulating elevators 3 and the entrances and exits located on one side of the two circulating elevators 3), and the remaining group is used as exits. Vehicles enter the ring road 6 from the social road through the aforementioned three entrances and enter the garage entrance position through the entry lane in the two-way road, waiting to be carried by the vehicle transfer chassis 5 and the translational extraction vehicle platform 4; and when the vehicle is taken out of the vertical garage, it enters the ring road 6 through the exit lane in the two-way road and exits to the social road through the exit.

[0029] In addition, a parking floor entrance and a parking floor exit are respectively arranged on the ground of each parking floor in front of the circulation elevator 3, that is, 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.

[0030] (S2) The vehicle enters the garage entrance and is transferred by the open car 6: like Figure 1-Figure 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.

[0031] 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.

[0032] 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.

[0033] (S3) The open car 6 transfers the vehicle to the designated parking floor: After the open car 34 rotates around the sprocket 31 to 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 bar platform 41 of the translational vehicle extraction platform 4 at the entrance of the parking floor is controlled to quickly translate outward to the descending path of the open car 34, and the vehicle loading platform of the open car 34 in the descending motion state passes through the gap of the bar platform 41, and the vehicle transfer chassis 5 and the vehicle thereon are seated on the bar platform 41, and then the bar platform 41 is controlled to retract to the ground of the parking floor. After that, the vehicle transfer chassis 5 is automatically controlled to drive down from the translational vehicle extraction platform 4 and automatically park at an empty parking space on the parking floor.

[0034] (S4) User picks up the car: When the user needs to pick up the car, he enters his license plate number on the large operation screen at the garage exit. The system then queries the parking floor and parking space number where the vehicle is located, and then controls the vehicle transfer chassis 5 on the parking floor to the bottom of the chassis of the corresponding vehicle to transport it to the exit of the parking floor, and then drives it to the translational vehicle extraction platform 4 at the exit of the parking floor. When the empty open car 34 rises and approaches the parking floor, the bar platform 41 of the translational vehicle extraction platform 4 is controlled to be translated in advance to the ascending path of the open car 34, and the open car 34 in the ascending state passes through the gap of the bar platform 41, and the vehicle transfer chassis 5 and the vehicle conversion thereon are synchronously seated on the vehicle loading 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 bar platform 41 at the exit of the parking lot is controlled to extend outward to the descending channel of the open car 34, and the translational vehicle extraction platform 4 is extracted to the vehicle and the vehicle transfer chassis 5 on the open car 34 by the same method as in step S3, and then the bar platform 41 is controlled to retract to the ground at the exit of the parking lot, and the vehicle transfer chassis 5 carries the vehicle to the designated pick-up position and then descends and detaches from the vehicle, finally facilitating the user to pick up the vehicle and leave.

[0035] The beneficial effects of this embodiment are: (1) A multi-way circulation elevator system is used. By arranging the circulation elevators back to back or overlapping each other to form a quadrilateral, a parking floor entrance and exit can be set up in at least two directions or four directions of the vertical underground garage, thereby improving the parking and retrieval efficiency of each parking floor; (2) 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; (3) 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.
