[0017] Example: Figure 1-13 As shown, this embodiment specifically relates to a vertical underground garage with a crawler-type circulating elevator system, which includes a segment shaft 1, a floor plate 2 and a crawler-type circulating elevator system 3.

[0018] like Figure 1-13 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. The crawler type circulating elevator system 3 is centrally arranged in the central space of the segment shaft 1, and the space it occupies is a cubic space as a whole.

[0019] like Figure 1-13 As shown, the crawler type circulating elevator system 3 includes two sets of sprockets 31, a crawler chain 32, a guide mechanism 33 and a plurality of open cars 34. The two sets of sprockets 31 are respectively arranged at the top and bottom of the space occupied by the crawler type circulating elevator system 3. The sprockets 31 are driven to rotate by a motor. The crawler chains 32 are correspondingly mounted on the two sets of sprockets 31 to form a circulating link. Under the transmission of the sprockets 31, the crawler chains 32 can circulate around the two sprockets 31. The crawler chain 32 on one side moves upward, and the crawler chain 32 on the other side moves downward. A plurality of open cars 34 are arranged at intervals on the crawler chain 32. The back of the open cars 34 is connected to a 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 chain 32 to prevent the vehicle loaded thereon from overturning.

[0020] like Figure 1-13As 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 Figure 1-13 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 from each other. 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 1-13 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. 9 and 10As 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 Fig. 9 , 10 As shown, the motion trajectory of the cross guide frame 3305 behind the open car 34 is described as follows: (S1) 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] (S2) 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] (S3) 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 vertical 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] ( S4 ) Based on steps S1 - S3 , the open cage 34 performs a circular rotation motion on the crawler chain 32 .

[0027] like Figure 1-11 As shown, the top floor of the segment shaft 1 on the ground 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. In addition, a parking floor entrance and a parking floor exit are respectively provided on the ground of each parking floor, and the parking floor entrance is arranged correspondingly in the area where the crawler chain 32 is driven downward, and the parking floor exit is arranged correspondingly in 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, and 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, and the longitudinal bars 4101 are spaced and distributed, 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 are lifted and lowered. A plurality of movable rollers 43 are provided on both sides of the bar platform 41, and the rollers 43 are driven by a motor and travel on the slide rails 42 on both sides.

[0028] 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 .

[0029] like Figure 1-13 As described above, the working method of the vertical underground garage with a crawler type circulating elevator system in this embodiment includes the following steps: (S1) The vehicle drives to the garage entrance and stops, and the vehicle transfer chassis 5 automatically drives under the chassis of the vehicle and lifts it off the ground, and then automatically drives to the corresponding translation type extraction vehicle platform 4 at the garage entrance to wait for transportation.

[0030] (S2) The movable extraction vehicle platform 4 is controlled to move 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 movable extraction vehicle platform 4 and lifts the vehicle transfer chassis 5 away from the movable extraction vehicle platform 4 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 rotates around the sprocket 31 to the descending channel.

[0031] (S3) 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 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 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.

[0032] (S4) When the user needs to pick up the car, the vehicle transfer chassis 5 is controlled to be under the chassis of the corresponding vehicle to carry it to the exit of the parking layer, and then driven to the translational pick-up vehicle platform 4 at the exit of the parking layer. When the empty open car 34 rises and approaches the parking floor, the movable 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 grid platform 41, and the vehicle transfer chassis 5 and the vehicle conversion thereon are synchronously seated on the 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 movable vehicle extraction platform 4 at the exit of the parking lot is controlled to extend outward to the descending channel of the open car 34, and the movable 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 movable vehicle extraction platform 4 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.

[0033] The beneficial effects of this embodiment are: (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; (2) 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.
