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 rotary 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, for the docking of a single elevator car, the entire circulating loop needs to stop running, wait for the docking of the single elevator car and the vehicle transfer plate to translate the vehicle to the docking floor, and then close the car door. The whole process takes a long time and 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 occur in local areas.

[0006] Therefore, improving the operating efficiency of the circulating elevator system in the vertical underground garage and solving the problem of local congestion are urgently needed by those skilled in the art. Summary of the Invention

[0007] The purpose of the present invention is to provide a method for efficiently transporting automobiles by using a rotary circulating elevator system in a vertical garage according to the deficiencies of the above-mentioned prior art. This method arranges a rotatable circulating elevator system in a segment shaft, with several open cars that can always maintain a vertical state spaced on the crawler chain of the circulating elevator system. The car carrier on the open car is composed of several load-bearing rods distributed at intervals, and a translational extraction vehicle platform that can extend and retract forward and backward is arranged on each parking floor. The translational extraction vehicle platform is composed of a grid platform. The car carrier on the open car can pass through the gap of the grid platform of the translational extraction vehicle platform to realize the transfer of the vehicle moving chassis and the vehicle to or from the translational extraction vehicle platform, and the rotation of the rotatable circulating elevator system can be driven by a circular track so that it can freely select the car pick-up and drop-off positions on the corresponding parking floors.

[0008] The object of the present invention is achieved by the following technical solutions:

[0009] A method for efficiently transporting vehicles using a rotary circulating elevator system in a vertical garage, the method comprising the following steps:

[0010] S1: Construct a vertical garage:

[0011] The vertical garage includes a segment shaft, floor slabs, and a rotary circulating 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. A circular through-hole is opened in the central area of each floor slab to form an elevator shaft in the central area of the segment shaft. The rotary circulating elevator system performs lifting and rotating operations in the elevator shaft;

[0012] The rotary circulating elevator system includes two groups of sprockets, crawler chains, and several open carriages; the two groups of sprockets are respectively arranged at the top and bottom of the segment shaft. Each group of sprockets includes a rotating shaft and gears arranged at both ends of the rotating shaft; the number of crawler chains is two, which are respectively assembled on the gears at both ends of the rotating shaft. A cross bar is arranged between the two crawler chains, and open carriages are suspended below the cross bar; the open carriage includes a fixing groove and several load-bearing rods horizontally inserted and welded in the fixing groove. The load-bearing rods are spaced apart from each other to form a vehicle-carrying platform. Diagonal stay rods are fixedly arranged at the front and rear ends of each load-bearing rod and converge on a transverse load-bearing rod. A rotatable mechanism is arranged between the transverse load-bearing rod and the cross bar to achieve articulated hoisting and rotation;

[0013] The rotary circulating elevator system further includes a structural frame and a circular track. The two ends of the rotating shaft of the sprocket are respectively supported on the structural frame. At least two circular tracks, upper and lower, are arranged on the structural frame. A plurality of driving mechanisms are arranged on the parking floors at the same height as the circular track to drive the circular track and the structural frame to perform rotational motion;

[0014] A plurality of translational extraction platforms are arranged at intervals along the circumferential direction of the parking floor near the elevator shaft. The translational extraction platform includes a grating platform and slide rails arranged on both sides of the grating platform. The grating platform includes a cross bar at the rear end and several longitudinal rods vertically welded to the cross bar. The longitudinal rods are spaced apart from each other and the gap is larger than the diameter of the load-bearing rod;

[0015] S2: When the vehicle travels to the garage entrance on the ground, control the vehicle transfer chassis to move under the vehicle and lift it to transfer the vehicle onto the translational extraction vehicle platform at the garage entrance;

[0016] S3: Drive the annular track to rotate through the drive mechanism to drive the overall rotation of the rotatable circulating elevator system, so as to rotate the open car to a preset angle and correspond to the vehicle at the garage entrance;

[0017] S4: When the open car in the ascending channel ascends close to the vehicle at the garage entrance, control the grating platform of the translational extraction vehicle platform at the garage entrance to translate outward from the ground onto the movement path of the open car. The car platform of the open car in the ascending movement state and without load passes through the gaps of the grating platform and lifts the vehicle transfer chassis off the grating platform to seat on the car platform of the open car. Then control the grating platform to retract to the ground and reset;

[0018] The open car carrying the vehicle and the vehicle transfer chassis rotates around the sprocket at the top into the descending channel. Then control the open car to turn 180° through the rotatable mechanism, so that the car platform and the vehicle on it resume the direction towards the floor slab;

[0019] S5: After the open car rotates 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 on the corresponding parking floor to quickly translate outward onto the descending path of the open car. The car platform of the open car in the descending movement state passes through the gaps of the grating platform, and the vehicle transfer chassis and the vehicle on it seat on the grating platform. Then control the grating platform to retract to the ground of the parking floor, and control the vehicle transfer chassis to drive off the translational extraction vehicle platform and automatically park in the empty parking space on this parking floor;

[0020] S6: When the user needs to pick up the vehicle, control the vehicle transportation chassis to carry the vehicle to the translational extraction vehicle platform on the parking floor; when the empty open car rises close to the corresponding parking floor, control the grating platform on the translational extraction vehicle platform to translate from the inside out to the movement path of the open car. The open car in the rising motion state passes through the gaps of the grating platform, and synchronously transfers the vehicle transportation chassis and the vehicle to the car-carrying platform of the open car; when the open car rises and rotates around the sprocket to the descending channel on the other side, drive the open car to rotate 180°, and control the translational extraction vehicle platform at the garage exit on the ground 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 transportation chassis on the open car. Then control the translational extraction vehicle platform to retract to the ground at the garage exit. The vehicle transportation chassis carries the vehicle to the designated pick-up position and then descends to separate from the vehicle, finally facilitating the user to pick up the vehicle and drive away.

[0021] Several drivable rollers are provided on both sides of the grating platform. The rollers are driven by motors and travel on the slide rails on both sides to complete the translational movement of the grating platform from the inside out or from the outside in.

[0022] In step S6, when the open car in the rising motion state passes through the gaps of the grating platform and synchronously transfers the vehicle transportation chassis and the vehicle to the car-carrying platform of the open car, drive the annular track to rotate through the driving mechanism to drive the overall rotation of the rotatable circulating elevator system, so as to rotate the open car to a preset angle and correspond to the translational extraction vehicle platform at the garage exit.

[0023] A rotatable base is provided at the bottom of the segment shaft. The bottom of the structural frame is installed on the rotatable base. The annular track is fixed on the structural frame. Several spaced convex columns are provided on the upper surface of the annular track. The driving mechanism arranged on the parking floor includes a fixed frame, a motor and an annular track driving gear. The motor is fixed on the parking floor through the fixed frame. An annular track driving gear is fixedly installed on the rotating shaft of the motor. The annular track driving gear drives the convex columns on the annular track to drive the rotation of the annular track and the structural frame.

[0024] The annular track is composed of two semi-circular arc segments. There are two reserved gaps between the two semi-circular arc segments. The reserved gaps are located in the area of the crawler chain.

[0025] The crawler chain is composed of inner chain links and outer chain links arranged alternately in sequence. The inner chain link includes two inner chain plates arranged in parallel 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 outer chain plates arranged in parallel 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. At the position where the cross bar is arranged, the cross bar and the pin shaft are of an integral structure.

[0026] The stay cables are arranged on the load-bearing rods at the outermost sides of the car-carrying platform. Two stay cables are arranged on each side, and the two stay cables are respectively connected to one end of the load-bearing rod and the fixed groove at the other end of the load-bearing rod.

[0027] The rotatable mechanism includes a fixed sleeve, a rotating platform and a hinge sleeve. The fixed sleeve is sleeved on the transverse load-bearing rod. The cross section of the transverse load-bearing rod is rectangular. The fixed sleeve has an inner cavity matching the transverse load-bearing rod to form mutual fixation. The hinge sleeve is sleeved on the cross bar to form a mutual hinge rotation relationship. The rotating platform is a circumferential rotation mechanism and is driven by a motor.

[0028] When the open car passes through the grating platform extending outwards, the lifting speed is controlled at 10-15 cm / s.

[0029] The advantages of the present invention are as follows:

[0030] (1) By adopting a circulating elevator system, the circular vertical underground garage can realize the vehicle transportation of multiple cars. Compared with the traditional single-car elevator system, the transportation capacity is effectively improved.

[0031] (2) By adopting an intermittent grating platform for the open car and the translational extraction car platform, the open car can pass through the gap of the grating platform of the translational extraction car platform during the normal rotation process, so as to transfer the vehicle moving 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 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.

[0032] (3) By controlling the rotation of the entire elevator system in the elevator shaft, the purpose of freely parking and retrieving cars at various circumferential angles can be achieved under a single circulation link, effectively saving the inconvenience of turning around and parking on the parking floor and realizing dynamic and flexible parking.

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

[0047] Example: As Figures 1-9As shown in the figure, this embodiment specifically relates to a method for efficiently transporting cars using a rotary circulating elevator system in a vertical garage. The method includes the following steps:

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

[0049] Before describing the specific method flow, the structure of the vertical underground garage will be specifically described. The vertical underground garage includes a segment shaft 1, floor slabs 2, and a rotatable circulating elevator system.

[0050] As Figures 1-3 shown, the segment shaft 1 is circular and composed of assembled caisson segments. The floor slabs 2 are arranged successively from top to bottom to divide the segment shaft 1 into several parking floors in the vertical direction. A circular through-hole is provided in the central area of each floor slab 2 to form an elevator shaft 6 located in the central area of the segment shaft 1. The elevator shaft 6 is for the rotation and circulating lifting actions of the aforementioned rotatable circulating elevator system.

[0051] As Figures 1-9 shown, the rotatable circulating elevator system includes two groups of sprockets 4, caterpillar chains 5, several open carriages 9, and a structural frame 3. The two groups 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 Figure 1 、 2 、3 shown, each group of sprockets 4 includes a rotating shaft 14 and gears provided at both ends of the rotating shaft 14. The two ends of the rotating shaft 14 are key-connected to the gears, and the end portions protruding from the gears penetrate through the structural frame 3 and are connected to the driving motor 13. The driving motor 13 is installed outside the structural frame 3 and drives the rotating shaft 14 to rotate. A bearing is provided between the rotating shaft 14 and the structural frame 3 to support the penetrated part thereof. The number of caterpillar chains 5 is two, which are respectively assembled on the gears at both ends of the rotating shaft 14, thus forming two circulating chains. Based on the fact that the gears at both ends of the rotating shaft 14 rotate synchronously, the two circulating chains also operate synchronously. Driven by the driving motor 13 and the rotating shaft 14, the upper and lower sprockets 4 rotate and drive the caterpillar chains 5 to rotate cyclically around the sprockets 4. One side of the caterpillar chain 5 around the sprocket 4 is in an ascending motion, and the other side of the caterpillar chain 5 around the sprocket 4 is in a descending motion.

[0052] As Figures 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.

[0053] like Figures 1-9As shown in the figure, several crossbars 15 are arranged at intervals along the extending and circulating direction between the two crawler chains 5. Both ends of the crossbar 15 are fixed on the crawler chain 5 and perform corresponding circular motions along with the crawler chain 5. An open car 9 is suspended below the crossbar 15. While remaining connected to the crossbar 15, the open car 9 can always maintain a vertical state and can rotate. The open car 9 includes a car-carrying platform, stay cables 903, a transverse load-bearing bar 904, and a rotatable mechanism 905. Among them, the car-carrying platform includes a fixing groove 902 and several load-bearing bars 901. The fixing groove 902 is in the shape of "[", and the ends of each load-bearing bar are inserted into the notch of the fixing groove 902 and fixed by welding or bolts. The adjacent load-bearing bars 901 are distributed at intervals. When the load-bearing bar 901 is fixed to the fixing groove 902, it should be ensured that the vehicle 16 has sufficient bearing capacity when parked on it. That is to say, each load-bearing bar 901 and the fixing groove 902 together form the car-carrying platform. Stay cables 903 are respectively arranged on the load-bearing bars 901 on both sides of the car-carrying platform. The lower ends of the stay cables 903 are respectively welded and fixed to the ends of the load-bearing bars 901 and the fixing groove 902, and the upper ends of the stay cables 903 intersect with each other and are welded into an integral structure with the transverse load-bearing bar 904. The rotatable mechanism 905 is arranged between the transverse load-bearing bar 904 and the crossbar 15 to achieve hoisting and rotation. The rotatable mechanism 905 includes a fixed sleeve, a rotating platform, and a hinge sleeve. The cross section of the transverse load-bearing bar 904 is rectangular, and the inner cavity shape of the fixed sleeve is the same and is sleeved on the transverse load-bearing bar 904 to form a fixed connection, and there is no relative rotation between the two. The hinge sleeve is sleeved on the crossbar 15. Based on the fact that the cross section of the crossbar 15 is circular, the hinge sleeve can rotate relative to the crossbar 15. The rotating platform directly uses a commercially available conventional rotating platform (a circumferential rotating mechanism 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 retrieving a vehicle, as the crawler chain 5 reciprocates, it is necessary to ensure that the opening surface of the car-carrying platform always faces the floor slab 2. Therefore, it is necessary to use the rotating platform for steering.

[0054] As Figures 1-9 shown, the crawler chain 5 is composed of inner chain links 501 and outer chain links 502 arranged alternately in sequence. The inner chain link 501 includes two parallel inner chain plates 505 and two groups of roller combinations 504 arranged between the two inner chain plates 505. The roller combination 504 is composed of a sleeve and rollers sleeved outside the sleeve; the outer chain link 502 includes two parallel outer chain plates 506 and two groups of pin shafts 503 arranged between the two outer chain plates 506. The outer chain link 502 is arranged between two adjacent inner chain links 501, and the two pin shafts 503 in the outer chain link 502 are respectively inserted into the sleeves of two adjacent inner chain links 501; at the setting position of the crossbar 15, the crossbar 15 and the pin shaft 503 are of an integral structure.

[0055] As shown Figures 1-5 in the figure, a number of translational extraction vehicle platforms 8 are arranged at intervals along the circumferential direction on the upper edge of each floor slab 2 near the elevator shaft 6. The translational extraction vehicle platform 8 includes a grid platform 801 and slide rails 803 arranged on both sides of the grid platform 801. The grid platform 801 includes a cross bar at the rear end and a number of longitudinal bars vertically welded to the cross bar. The longitudinal bars are distributed at intervals, and the gap between them is greater than the diameter of the load-bearing bar 901, so that the car-carrying platform can pass through the grid platform 801 without being affected during the mutual lifting movement. A number of movable rollers 802 are arranged on both sides of the grid platform 801. The rollers 802 are driven by a motor and run on the slide rails 803 on both sides.

[0056] (S2) A number of garage entrances and garage exits are provided on the top floor of the segment shaft 1 located on the ground. Translational extraction vehicle platforms 8 are provided at both the garage entrance and the garage exit. When the vehicle 16 travels to the garage entrance on the ground, the control vehicle transfer chassis 17 travels to the bottom of the vehicle 16 and is lifted to transfer the vehicle 16 onto the translational extraction vehicle platform 8 at the garage entrance. The vehicle 16 waits for the open car 9 to pick up the vehicle. In this embodiment, there are two groups of front and rear rollers on the lower bottom surface of the vehicle transfer chassis 17, and the transverse length of the rollers is greater than the transverse distance between at least two load-bearing bars 901.

[0057] (S3) The driving mechanism 12 drives the annular track 10 to rotate to drive the overall rotation of the rotatable circulating elevator system, rotates the open car 9 thereon to a preset angle, and corresponds to the vehicle 16 and the translational extraction vehicle platform 8 at the garage entrance.

[0058] (S4) After the overall rotation of the rotatable circulating elevator system is completed, the selected open car 9 for picking up the vehicle is selected. When the open car 9 in the ascending channel rises close to the vehicle 16 at the garage entrance, the grid platform 801 of the translational extraction vehicle platform 8 at the garage entrance is controlled to translate outward from the ground onto the movement path of the open car 9. The car-carrying platform of the open car 9 in the ascending movement state and without load passes through the gap of the grid platform 801 and lifts the vehicle transfer chassis 17 off the grid platform 801 to seat on the car-carrying platform of the open car 9. Then, the grid platform 801 is controlled to retract to the ground to reset. It should be noted that when the open car 9 passes through the grid platform 801 extending outward, the lifting speed is controlled at 10-15 cm / s.

[0059] The open car 9 carrying the vehicle 16 and the vehicle transfer chassis 17 rotates around the sprocket 4 at the top to the descending channel, and then the open car 9 is controlled to turn 180° through the rotatable mechanism 905 so that the car-carrying platform and the vehicle 16 thereon are restored to the direction facing the floor slab 2.

[0060] (S5) After the open car 9 rotates around the sprocket 4 and reaches 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, control the grating platform 801 of the translational extraction car platform 8 at the entrance of the parking floor to quickly translate outward onto the descending path of the open car 9. The open car 9 in the descending motion state passes through the gap of the grating platform 801, and the vehicle transfer chassis 17 and the vehicle 16 thereon are seated on the grating platform 801 of the translational extraction car platform 8. Then control the translational extraction car platform 8 to retract to the ground of the parking floor. Then automatically control the vehicle transfer chassis 17 to drive down from the translational extraction car platform 8 and automatically park in the empty parking space on this parking floor.

[0061] (S6) When the user needs to pick up the car, control the vehicle transfer chassis 17 to move under the chassis of the corresponding vehicle 16 and carry it to the exit of this parking floor, and drive onto the translational extraction car platform 8 at the exit of this parking floor. When the empty open car 9 rises close to this parking floor, control the translational extraction car platform 8 to translate in advance onto the ascending path of the open car 9. The open car 9 in the ascending motion state passes through the gap of the grating platform 801, and synchronously transfer and seat the vehicle transfer chassis 17 and the vehicle 16 thereon onto the car-carrying platform of the open car 9.

[0062] After the open car 9 receives the vehicle 16 and the vehicle transfer chassis 17, drive the annular track 10 to rotate through the driving mechanism 12 to drive the overall rotation of the rotatable circulating elevator system, so as to rotate the open car 9 to a preset angle and correspond to the translational extraction car platform 8 located at the garage exit.

[0063] At the same time, when the open car 9 is in the ascending motion and rotates around the sprocket 4 to the descending channel on the other side, drive the car-carrying platform to rotate the angle, and control the translational extraction car platform 8 at the parking lot exit to extend outward onto the descending channel of the open car 9. Use the same method as in step S5 to make the translational extraction car platform 8 extract the vehicle 16 and the vehicle transfer chassis 17 on the open car 9. Then control the translational extraction car platform 8 to retract to the ground of the parking lot exit. The vehicle transfer chassis 17 transports the vehicle to the designated car-picking-up position and then descends to separate from the vehicle, and finally facilitates the user to pick up the car and drive away.

[0064] The advantages of this embodiment are:

[0065] (1) By adopting a circulating elevator system, the circular vertical underground garage can realize the vehicle transportation of multiple cars. Compared with the traditional single-car elevator system, the transportation capacity is effectively improved;

[0066] (2) By adopting an intermittent grid platform for the open car and the translation extraction vehicle platform, the open car can pass through the gaps of the grid platform of the translation extraction vehicle platform during normal rotation, so as to transfer the vehicle transportation chassis and the vehicle onto or out of 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.

[0067] (3) By controlling the rotation of the entire elevator system in the elevator shaft, the purpose of freely parking and retrieving vehicles at various circumferential angles can be achieved under a single-loop link, effectively saving the inconvenience of turning around for parking on the parking floor and realizing dynamic and flexible parking.
