DETAILED DESCRIPTION

[0017] 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: Example: Figure 1-15 As shown, this embodiment specifically relates to a working method of a multi-circulation elevator system in a vertical garage based on a rotating platform, and the working method includes the following steps: (S1) Construction of vertical underground garage: The vertical underground garage includes a segment shaft 1, a floor plate 2, a multi-circulation elevator system and a rotatable waiting platform 6.

[0018] The segment shaft 1 is circular and composed of caisson segments, and is arranged in the space below the ground. 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. A square through hole is opened in the central area of ​​each floor plate 2 to form an elevator shaft located in the central area of ​​the segment shaft 1. The multi-circulation elevator system is arranged in the elevator shaft, and the space it occupies is a cubic space as a whole.

[0019] like Figure 3 and 4 As shown, the multi-circulation elevator system is composed of four groups of circulation elevators 3, and the four groups of circulation elevators 3 are sequentially overlapped to form a quadrilateral structure. Figure 1-15 As shown, 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.

[0020] like Figure 1-15As 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.

[0021] like Fig.10 , 11 As shown in Figures 13, the open elevator 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 on it. 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.

[0022] like Figure 1-15 As 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.12As 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.

[0023] like Figure 1 , 2 , 10, 11, and 12, 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.

[0024] (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.

[0025] (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.

[0026] (d) Based on steps ac, the open car 34 performs a circular rotation motion on the crawler chain 32 .

[0027] like Figure 1-15 As shown, the rotatable waiting platform 6 is arranged on the outer ground of the top layer of the segment shaft 1, specifically, it is arranged on the outer periphery of the multi-circulation elevator system. The rotatable waiting platform 6 includes an inner ring rotating platform 61 and an outer ring road 62. The inner ring rotating platform 61 rotates around the top of the multi-circulation elevator system, and the outer ring road 62 is arranged on the outer ring of the inner ring rotating platform 61 and contacts each other, so that vehicles can drive from the outer ring road 62 to the inner ring rotating platform 61. Figure 4 , 5 As shown in Figure 6, the inner ring rotating platform 61 includes a double-row annular track 613, an annular platform 615 and a horizontal rotating driving mechanism 614. The bottom of the annular platform 615 is provided with a universal running wheel 612 running on the double-row annular track 613. The outer edge of the annular platform 615 has a convex tooth 611. The horizontal rotating driving mechanism 614 drives the annular platform 615 to rotate by meshing with the convex tooth 611 on the outer edge of the annular platform 615. The horizontal rotating driving mechanism 614 includes a motor and a pinion gear keyed to the motor output shaft. The pinion gear meshes with the convex tooth 611 of the annular platform 615 to achieve meshing transmission. A notch is provided at the position where the outer ring road 62 contacts the inner ring rotating platform 61 for the installation of the horizontal rotating driving mechanism 614.

[0028] like Figure 1-15As shown, four groups of garage entrances and exits are arranged on the top layer of the segment shaft 1 (i.e., the top of the multi-circulation elevator system), each group of garage entrances and exits corresponds to four groups of circulation elevators 3, each group of garage entrances and exits includes a garage entrance and a garage exit, and each garage entrance and garage exit position has a corresponding translational extraction vehicle platform 4, that is, two translational extraction vehicle platforms 4 are arranged on each side of the multi-circulation elevator system, and the translational extraction vehicle platform 4 is arranged on the inner ring rotating platform 61. 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 and the gap is greater than the diameter of the load-bearing bar 3402, so that they can pass through without being affected when they move up and down. A plurality of movable rollers are arranged on both sides of the bar platform 41, and the rollers are driven by a motor and move on the slide rails 42 on both sides.

[0029] In addition, if Figure 8 As shown, a parking floor entrance and a parking floor exit are respectively arranged on the ground of each parking floor directly in front of the circulating elevator 3. The parking floor entrance corresponds to the area where the crawler chain 32 drives downward, and the parking floor exit corresponds to the area where the crawler chain 32 drives upward; the parking floor entrance and the parking floor exit are both provided with a translational extraction vehicle platform 4.

[0030] It should be noted that a vehicle transport chassis 5 is provided at the entrance of the garage, and two sets of front and rear running wheels 51 are provided on the lower bottom surface of the vehicle transport chassis 5, and the lateral length of the running wheels 51 is greater than the lateral distance between at least two load-bearing rods 3402. The vehicle transport chassis 5 can be raised and lowered in a small range to realize the carrying and removal of the vehicle chassis.

[0031] (S2) The outer ring road 62 is connected to the public road on the ground. The vehicle enters the outer ring road 62 via the public road. The outer ring road 62 is provided with at least two lanes, the outer lane is used for normal driving, and the inner lane is used for stopping and waiting for a car after entering. When the vehicle is driving on the outer lane of the outer ring road 62, the parking position is selected based on the indicator light at the garage entrance, that is, the garage entrance is provided with an indicator light, which will prompt whether the translational extraction vehicle platform 4 at the garage entrance is idle. If the indicator light prompts that the translational extraction vehicle platform 4 at the garage entrance is idle, the vehicle is changed to the inner lane of the outer ring road 62 and stops at the position corresponding to the idle translational extraction vehicle platform 4. The vehicle transfer chassis 5 automatically drives to the bottom of the vehicle and supports and lifts the vehicle off the ground, and carries the vehicle to the corresponding idle translational extraction vehicle platform 4 on the inner ring rotating platform 61.

[0032] (S3) Then, the idle circulating elevators 3 in the multi-circulation elevator system are checked, and the inner ring rotating platform 61 is controlled to rotate so that the translational pick-up vehicle platform 4 carrying the vehicle can rotate to the designated circulating elevator 3 position, waiting for the open car 34 on the circulating elevator 3 to come and pick up the vehicle.

[0033] (S4) The movable extraction vehicle platform 4 is controlled to move 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 ascending state passes through the gap of the movable extraction vehicle platform 4 and lifts the vehicle transfer chassis 5 off the movable extraction vehicle platform 5 to sit on the open car 34. Then, the movable extraction vehicle platform 4 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.

[0034] (S5) 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 extraction vehicle 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 open car 34 in the descending 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 of the translational extraction vehicle platform 4, and then the translational extraction vehicle platform 4 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 extraction vehicle platform 4 and automatically park at an empty parking space on the parking floor.

[0035] (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. When the empty open car 34 rises and approaches the parking layer, the translational extraction vehicle platform 4 is controlled to translate 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 grid platform 41, and the vehicle transfer chassis 5 and the vehicle on it are synchronously transferred to the platform of the open car 34. When the open car 34 moves upward and rotates around the sprocket 31 to the descending channel on the other side, the inner ring rotating platform 61 is controlled to rotate so that the idle translational extraction vehicle platform 4 can be aligned with the open car 34 on the descending channel, and then the translational pick-up vehicle platform 4 on the inner circle rotating platform 61 is controlled to extend outward to the descending channel of the open car 34, and the translational pick-up vehicle platform 4 is used to pick up the vehicle and the vehicle transfer chassis 5 on the open car 34 in the same way as in step S5, and then the translational pick-up vehicle platform 4 is controlled to retract onto the inner circle rotating platform 61, and the vehicle transfer chassis 5 carries the vehicle to the inner lane on the outer circle annular road 62 and then descends to separate from the vehicle, finally facilitating the user to pick up the vehicle and drive away.

[0036] The beneficial effects of this embodiment are: (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; (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; (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; (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.
