[0002] How to provide enough parking spaces in a limited space is a problem that everyone has been working on solving. Therefore, vertical underground garages came into being.

[0003] The vertical underground garage formed by vertical excavation is divided into several floors, each of which can be used for parking. Cars drive into the entrance of the vertical underground garage on the ground and are transported to the corresponding floor for parking by vertical elevators. However, for such underground garages with great depth and large traffic volume, conventional vertical elevators are insufficient in transportation efficiency and cannot solve the problem of large traffic volume transportation in urban areas. It is necessary to install other types of elevator systems in the vertical underground garage to solve the problem of great depth and large traffic volume.

[0004] At present, there are also some circulating elevator systems, in which multiple sets of elevators are arranged on the entire circulation circle. However, the parking of a single elevator car requires the entire circulation circle to stop running, waiting for the single elevator car to dock and the vehicle transport plate to move the vehicle to the docking floor before closing the car door. The whole process takes a long time, which seriously reduces the operating efficiency of the entire circulating elevator system.

[0005] In addition, the parking floors of the vertical underground garage are arranged in a ring shape. When vehicles are concentrated in and out from fixed exits and entrances, congestion will cause local areas.

[0037] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0038] Example: Figure 1-9 As shown, this embodiment specifically relates to a vertical underground garage with a rotatable circulating elevator system, which includes a segment shaft 1, a floor plate 2 and a rotatable circulating elevator system.

[0039] like Figure 1-3 As shown, the segment shaft 1 is circular and is composed of caisson segments, and the floor plates 2 are arranged in sequence from top to bottom to divide the segment shaft 1 into a number of parking floors in the vertical direction. A circular through hole is opened in the central area of ​​each floor plate 2 to form an elevator shaft 6 located in the central area of ​​the segment shaft 1, and the elevator shaft 6 is used for the rotation and circulation lifting action of the aforementioned rotatable circulating elevator system.

[0040] like Figure 1-9 As shown, the rotatable circulating elevator system includes two sets of sprockets 4, crawler chains 5, a plurality of open cars 9 and a structural frame 3; the two sets of sprockets 4 are respectively arranged at the top and bottom of the elevator shaft 6 and are positioned and installed through the structural frame 3, as shown in FIG. Figure 1 , 2 As shown in Figure 3, each set of sprockets 4 includes a rotating shaft 14 and gears arranged at both ends of the rotating shaft 14. The two ends of the rotating shaft 14 are connected with the gear keys and the end protruding from the gear passes through the structural frame 3 and is connected to the driving motor 13. The driving motor 13 is installed on the outside of the structural frame 3 and drives the rotating shaft 14 to rotate. A bearing is arranged between the rotating shaft 14 and the structural frame 3 to support its penetrating part. There are two crawler chains 5, which are respectively assembled on the gears at both ends of the rotating shaft 14, thereby forming two circulating links. Based on the synchronous rotation of the gears at both ends of the rotating shaft 14, the two circulating links also operate synchronously. Driven by the driving motor 13 and the rotating shaft 14, the upper and lower sprockets 4 rotate and drive the crawler chain 5 to rotate around the sprocket 4. The crawler chain 5 on one side of the sprocket 4 moves upward, and the crawler chain 5 on the other side of the sprocket 4 moves downward.

[0041] like Figure 1-9As shown, the structural frame 3 is two sets of steel structure vertical frames, which are formed into a whole by being installed and combined with the sprocket 4 and the crawler chain 5. A rotatable base 7 is arranged at the bottom thereof, and a ball support is arranged between the rotatable base 7 and the structural frame 3 to achieve support and rotation support for the structural frame 3. It should be noted that the rotatable base 7 does not provide power support for the rotation of the structural frame 3. At least two circular tracks 10 are arranged in the vertical direction of the structural frame 3. A plurality of driving mechanisms 12 are arranged on the parking layer at the same height as the circular track 10 to drive the circular track 10 and the structural frame 3 to rotate. Specifically, the circular track 10 is fixed on the structural frame 3. A plurality of bosses 11 are evenly spaced on the upper surface of the circular track 10. The driving mechanism 12 includes a fixed frame, a motor and a circular track driving gear. The fixed frame is installed at the edge of the floor plate and close to the elevator shaft 6. The motor is installed on the fixed frame. The circular track driving gear is installed on the motor and driven by the motor. The circular track driving gear moves the bosses 11 on the circular track 10 under rotation to drive the circular track 10 and the structural frame 3 to rotate. The distribution spacing of the bosses 11 corresponds to the tooth pitch of the circular track driving gear, so that the circular track driving gear can continuously drive the circular track 10 to rotate. It should be noted that, Figure 2 and 3 As shown, the annular track 10 is composed of two semicircular arc segments, and there are two reserved gaps between the two semicircular arc segments. The reserved gaps are located in the area of ​​the crawler chain 5 to provide a lifting channel for the lifting of the open car 9 to avoid obstruction.

[0042] like Figure 1-9As shown, a number of cross bars 15 are arranged at intervals between the two crawler chains 5 along the extending circulation direction thereof. The two ends of the cross bars 15 are fixed on the crawler chains 5 and perform corresponding circulation movements with the crawler chains 5. An open car 9 is hoisted under the cross bars 15. The open car 9 can always remain in a vertical state and can rotate while being connected to the cross bars 15. The open car 9 includes a vehicle loading platform, an inclined suspension rod 903, a transverse load-bearing rod 904 and a rotatable mechanism 905, wherein the vehicle loading platform includes a fixed groove 902 and a number of load-bearing rods 901. The fixed groove 902 is in a "[" shape. The end of each load-bearing rod is inserted into the notch of the fixed groove 902 and is fixed by welding or bolts. Adjacent load-bearing rods 901 are spaced apart. When the load-bearing rods 901 are fixed to the fixed groove 902, it should be ensured that there is enough space for the vehicle 16 to be parked thereon. That is to say, each load-bearing rod 901 and the fixing groove 902 together form a vehicle-carrying platform, and oblique suspension rods 903 are respectively arranged on the load-bearing rods 901 on both sides of the vehicle-carrying platform, and the lower ends of the oblique suspension rods 903 are respectively welded and fixed to the ends of the load-bearing rods 901 and the fixing grooves 902, and the upper ends of the oblique suspension rods 903 intersect with each other and are welded to the transverse load-bearing rods 904 as an integrated structure, and a rotatable mechanism 905 is arranged between the transverse load-bearing rods 904 and the cross bar 15 to realize lifting and rotation. The rotatable mechanism 905 includes a fixed sleeve, a rotating platform and an articulated sleeve. The cross-section of the transverse load-bearing rod 904 is rectangular, and the inner cavity shape of the fixed sleeve is the same as that of the transverse load-bearing rod 904 and is mounted on the transverse load-bearing rod 904 to form a fixed connection. The two will not rotate relative to each other, and the articulated sleeve is mounted on the cross bar 15. Based on the circular cross-section of the cross bar 15, the articulated sleeve can rotate relative to the cross bar 15, and the rotating platform directly adopts a conventional rotating platform on the market (circumferential rotating mechanism and driven by a motor). The rotation angle of the rotating platform is required to be between 0-180°. When the open car 9 has the task of parking and picking up a car, with the reciprocating transmission of the crawler chain 5, it is necessary to ensure that the opening surface of the vehicle-carrying platform is always facing the floor plate 2, so it is necessary to use the rotating platform for steering.

[0043] like Figure 1-9 As shown, the crawler chain 5 is composed of inner links 501 and outer links 502 which are arranged alternately in sequence. The inner link 501 includes two inner link plates 505 which are arranged in parallel and two groups of roller assemblies 504 which are arranged between the two inner link plates 505. The roller assembly 504 is composed of a sleeve and a roller which is sleeved outside the sleeve. The outer link 502 includes two outer link plates 506 which are arranged in parallel and two groups of pins 503 which are arranged between the two outer link plates 506. The outer link 502 is arranged between two adjacent inner links 501. The two pins 503 in the outer link 502 are respectively inserted into the sleeves of the two adjacent inner links 501. At the setting position of the cross bar 15, the cross bar 15 and the pins 503 are in an integrated structure.

[0044] like Figure 1-5 As shown, a plurality of translation-type extraction vehicle platforms 8 are arranged at intervals along the circumferential direction at the upper edge of each floor plate 2 near the elevator shaft 6. The translation-type extraction vehicle platform 8 includes a bar platform 801 and slide rails 803 arranged on both sides of the bar platform 801. The bar platform 801 includes a cross bar at the rear end and a plurality of longitudinal bars vertically welded to the cross bar. The longitudinal bars are spaced apart and the gap is greater than the diameter of the load-bearing rod 901, so that the vehicle platform can pass through the bar platform 801 without being affected when the two sides are lifted and lowered. A plurality of movable rollers 802 are arranged on both sides of the bar platform 801. The rollers 802 are driven by a motor and move on the slide rails 803 on both sides.

[0045] like Figure 1 As shown, the top floor of the segment shaft 1 on the ground is provided with a plurality of garage entrances and garage exits, and a translational extraction vehicle platform 8 is provided at both the garage entrance and the garage exit.

[0046] like Figure 4-7 As shown, in this embodiment, the vehicle 16 is moved to the vehicle loading platform of the open car 9 and the floor plate 2 by means of a vehicle transfer chassis 17. The lower bottom surface of the vehicle transfer chassis 17 is provided with two sets of front and rear rollers, and the lateral length of the rollers is greater than the lateral distance between at least two load-bearing rods 901.

[0047] like Figure 1-9 As shown, this embodiment specifically relates to a specific working method of a vertical underground garage with a rotatable circulating elevator system:

[0048] (S1) The vehicle 16 drives on the ground to the garage entrance and stops. The vehicle transfer chassis 17 automatically drives under the chassis of the vehicle 16 and lifts it off the ground. Then, it automatically drives to the corresponding translation type extraction vehicle platform 8 at the garage entrance to wait for transportation.

[0049] (S2) The circular track 10 is driven by the driving mechanism 12 to drive the entire rotatable circulating elevator system to rotate, so as to rotate the open car 9 to the required angle, that is, to make the empty open car 9 ready to receive the vehicle transfer chassis 17 and the vehicle 16 on the translational extraction vehicle platform 8.

[0050] (S3) The movable extraction vehicle platform 8 is controlled to move outward from the ground to the movement path of the open car 9. The empty open car 9 on the crawler chain 5 in the ascending state passes through the gap of the movable extraction vehicle platform 8 and lifts the vehicle transfer chassis 17 off the movable extraction vehicle platform 8 to sit on the open car 9. Then, the movable extraction vehicle platform 8 is controlled to retract to the ground and reset. At the same time, the open car 9 carrying the vehicle 16 and the vehicle transfer chassis 17 rotates around the sprocket 4 to the descending channel.

[0051] (S4) Figure 1 , 4 As shown in Figures 5 and 6, after the open car 9 rotates around the sprocket 4 to the descending channel, the vehicle loading platform of the open car 9 will face inward. Therefore, it is necessary to drive the mounted vehicle loading platform to rotate 180° through the rotatable mechanism 905 so that the open car 9 can return to the direction toward the floor plate 2.

[0052] (S5) After the open car 9 rotates around the sprocket 4 to the descending channel, according to the required parking floor specified by the algorithm, before the open car 9 is about to descend to the corresponding parking floor, the bar platform 801 of the translational extraction vehicle platform 8 at the entrance of the parking floor is controlled to quickly translate outward to the descending path of the open car 9, and the open car 9 in the descending state passes through the gap of the bar platform 801, and the vehicle transfer chassis 17 and the vehicle 16 thereon are seated on the bar platform 801 of the translational extraction vehicle platform 8, and then the translational extraction vehicle platform 8 is controlled to retract to the ground of the parking floor. After that, the vehicle transfer chassis 17 is automatically controlled to drive down from the translational extraction vehicle platform 8 and automatically park at an empty parking space on the parking floor.

[0053] (S6) When the user needs to pick up the vehicle, the vehicle is controlled to move the chassis 17 to the bottom of the chassis of the corresponding vehicle 16 to transport it to the exit of the parking layer, and then drive to the translational extraction vehicle platform 8 at the exit of the parking layer. When the empty open car 9 rises and approaches the parking floor, the translational vehicle extraction platform 8 is controlled to be translated in advance to the ascending path of the open car 9, and the open car 9 in the ascending state passes through the gap of the grid platform 801, and the vehicle transfer chassis 17 and the vehicle 16 on it are synchronously transferred and seated on the vehicle loading platform of the open car 9. When the open car 9 rises and rotates around the sprocket 4 to the descending channel on the other side, the vehicle loading platform is driven to rotate, and the translational vehicle extraction platform 8 at the exit of the parking lot is controlled to extend outward to the descending channel of the open car 9. The same method as in step S5 is used to make the translational vehicle extraction platform 8 extract the vehicle 16 and the vehicle transfer chassis 17 on the open car 9, and then the translational vehicle extraction platform 8 is controlled to retract to the ground at the exit of the parking lot, and the vehicle transfer chassis 17 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.

[0054] The beneficial effects of this embodiment are:

[0055] (1) 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;

[0056] (2) The open car and the translational vehicle extraction platform adopt an interval grid platform, which allows the open car to pass through the grid platform gap of the translational vehicle extraction platform during normal rotation, so as to transfer the vehicle transfer chassis and the vehicle to the translational vehicle extraction platform or take it out from the translational vehicle extraction platform. 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 greatly shortens the parking and retrieval time;

[0057] (3) By controlling the rotation of the entire elevator system in the elevator shaft, the purpose of freely parking and picking up vehicles at various angles in the circular direction can be achieved even in a single-loop link, effectively saving the inconvenience of parking in the parking floor and realizing dynamic and flexible parking.
