Description

Technical Field

[0001] The present invention belongs to the technical field of vertical underground garages, and particularly relates to a vertical garage with a multi-way circulating elevator system. Background Art

[0002] How to provide enough parking spaces in a limited space has been a problem that everyone has 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. It is necessary to set up other types of elevator systems 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, the docking of a single elevator car requires the entire circulating loop to stop running and wait for the docking of the single elevator car, which seriously reduces the operating efficiency of the entire circulating elevator system. Summary of the Invention

[0005] The purpose of the present invention is to provide a vertical garage with a multi-way circulating elevator system according to the deficiencies of the above-mentioned prior art. The vertical garage sets up a multi-way circulating elevator system in the central area of the segment shaft to realize that there are parking floor entrances and exits in multiple directions within the parking floor, improving the overall operation efficiency; and by arranging a number of open carriages that can always maintain a vertical state at intervals on the crawler chain of the circulating elevator system, the car-carrying plate on the open carriage is composed of a number of load-bearing rods distributed at intervals, and a translational extraction vehicle platform that can be telescoped back and forth is arranged on each parking floor. The translational extraction vehicle platform is composed of a grid platform. The car-carrying plate on the open carriage can pass through the gap of the grid platform of the translational extraction vehicle platform to realize the transfer of the vehicle transfer chassis and the vehicle to or from the translational extraction vehicle platform.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0007] A vertical garage with a multi-way circulating elevator system, the vertical garage includes a segment shaft, floor slabs, and a multi-way circulating elevator system. The segment shaft is assembled by segment linings. The multi-way circulating elevator system is centrally arranged in the central area of the segment shaft. The floor slabs are arranged successively from top to bottom to divide the segment shaft into several parking floors in the vertical direction; wherein:

[0008] The multi-loop elevator system is composed of two or four groups of loop elevators; when the multi-loop elevator system is composed of two groups of loop elevators, the two groups of loop elevators are arranged back to back; when the multi-loop elevator system is composed of four groups of loop elevators, the four groups of loop elevators are sequentially lapped to form a quadrilateral structure;

[0009] Each group of loop elevators includes two groups of sprockets, a crawler chain, a guiding mechanism, and several open carriages. The two groups of sprockets are respectively arranged at the top and bottom of the segment shaft. The crawler chain is fitted and sleeved on the two sprockets and driven by the sprockets to rotate in a cycle; the open carriages are fixedly spaced on the crawler chain. The open carriage includes a vertical base plate and several load-bearing rods horizontally welded to the bottom of the front surface of the vertical base plate, and the load-bearing rods are distributed at intervals; the guiding mechanism is arranged on the back surface of the vertical base plate to guide the open carriage so that it always maintains a vertical state;

[0010] On the ground of each parking floor, there are the same number of entrances and exits as the number of loop elevators. Each group of entrances and exits includes a parking floor entrance and a parking floor exit; the parking floor entrance is correspondingly arranged on the side where the crawler chain drives downward, and the parking floor exit is correspondingly arranged on the side where the crawler chain drives upward; both the parking floor entrance and the parking floor exit are provided with a translational extraction vehicle platform. The translational extraction vehicle platform includes a grid platform and slide rails arranged on both sides of the grid platform. The grid platform includes a cross bar at the rear end and several vertical bars perpendicularly welded to the cross bar, and the vertical bars are distributed at intervals and the gap is larger than the diameter of the load-bearing rod.

[0011] The top floor of the segment shaft located on the ground is provided with a garage entrance and exit. The number of groups of the garage entrance and exit is the same as the number of loop elevators; each group of the garage entrance and exit includes a garage entrance and a garage exit, and both the garage entrance and the garage exit are provided with the translational extraction vehicle platform.

[0012] The multi-loop elevator system is composed of two groups of loop elevators combined back to back. A circular road is arranged around the periphery of the top floor of the segment shaft located on the ground. There are four entrances and exits connecting to the roads on the circular road, and two two-way roads connecting the garage entrances and exits are arranged on the circular road.

[0013] The multi-loop elevator system is composed of four groups of loop elevators sequentially lapped to form a quadrilateral structure. The top floor of the segment shaft located on the ground is in a quadrilateral structure, and each side is respectively provided with a two-way road leading to the road.

[0014] Several walkable rollers are arranged on both sides of the grid platform. The rollers are driven by a motor and travel on the slide rails on both sides.

[0015] 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.

[0016] One of the pin shafts in the outer chain link protrudes from the outer chain plate, and relative rotation can occur between the pin shaft and the outer chain plate. The back surface of the vertical base plate in the open car is fixedly connected to the end of the pin shaft, and the other end of the pin shaft also protrudes from the outer chain plate and is fixedly connected to the guiding mechanism.

[0017] The guiding mechanism includes a cross guiding frame and a guiding base plate. The center of the cross guiding frame is fixedly connected to the end of the pin shaft. Four end parts of the cross guiding frame are respectively fixedly provided with guiding columns. Two sets of guiding grooves are opened on the vertically arranged guiding base plate. One set of guiding grooves is used to guide the ascent of the open car, and the other set of guiding grooves is used to guide the descent of the open car. The guiding groove includes a vertically centered central groove and two vertical side grooves arranged on both sides of the vertical central groove. The vertical central groove is used to guide the guiding columns at the vertical two ends of the cross guiding frame, and the vertical side grooves are used to guide the guiding columns at the horizontal two ends of the cross guiding frame. Among them, the top of the outer vertical side groove in each set of guiding grooves also has an arc-shaped guiding groove to adapt to the turning of the open car at the sprocket wheel.

[0018] A vehicle transfer chassis is arranged at the garage entrance. Two sets of front and rear traveling wheels are arranged on the lower bottom surface of the vehicle transfer chassis. The transverse length of the traveling wheels is greater than the transverse distance between at least two load-bearing rods.

[0019] After the vehicle stops on the vehicle transfer chassis at the garage entrance, the vehicle transfer chassis automatically moves onto the translational extraction vehicle platform. The translational extraction vehicle platform translates outward from the ground to the movement path of the open car. The open car on the ascending crawler chain passes through the gap of the translational extraction vehicle platform and lifts the vehicle transfer chassis off the translational extraction vehicle platform to seat on the open car. Then, the translational extraction vehicle platform is controlled to retract to the ground;

[0020] According to the parking floor where the vehicle needs to stop, when the open car is in the descending state and approaching the parking floor to be stopped, control the translational extraction car platform on the corresponding parking floor to translate outward to the movement path of the open car. The open car in the descending state passes downward through the gap of the translational extraction car platform, leaving the vehicle transportation chassis and the vehicle on it on the translational extraction car platform. Then, control the translational extraction car platform to retract inward to the ground of the parking floor.

[0021] The advantages of the present invention are as follows:

[0022] (1) By adopting a multi-loop elevator system, the loop elevators are arranged back to back or overlapped with each other to form a quadrilateral, so that parking floor entrances and exits can be arranged in at least two directions or four directions of the vertical underground garage, improving the efficiency of parking and retrieving vehicles on each parking floor;

[0023] (2) In the circular vertical underground garage, by adopting a loop elevator system, multi-carriage vehicle transportation can be realized. Compared with the traditional single-carriage elevator system, the transportation capacity is effectively improved;

[0024] (3) The open car and the translational extraction car platform adopt an intermittent grid platform, so that the open car can pass through the gap of the grid platform of the translational extraction car platform during normal rotation, in order to transfer the vehicle transportation chassis and the vehicle to or take out from the translational extraction car platform. The vehicle can be parked and retrieved without stopping the elevator system, greatly improving the operation efficiency of the entire vertical underground garage and significantly shortening the parking and retrieving time.

[0041] The features of the present invention and other related features are further described in detail below with reference to the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the same industry:

[0042] As Figure 1-16 , the respective marks in the figure are: segment shaft 1, floor slab 2, circulating elevator 3, sprocket 31, crawler chain 32, pin shaft 3201, inner link 3202, outer link 3203, inner link plate 3204, roller assembly 3205, outer link plate 3206, guiding mechanism 33, guiding substrate 3301, outer vertical side groove 3302, inner vertical side groove 3303, vertical central groove 3304, cross guide frame 3305, open car 34, vertical substrate 3401, load-bearing rod 3402, guardrail 3403, translation extraction vehicle platform 4, grid platform 41, longitudinal rod 4101, cross bar 4102, slide rail 42, roller 43, vehicle transfer chassis 5, traveling wheel 51, circular road 6.

[0043] Example: As Figure 1-16 shown, this embodiment specifically relates to a vertical garage with a multi-loop elevator system. The vertical garage includes a segment shaft 1, a floor slab 2, and a multi-loop elevator system.

[0044] As Figure 1-16 shown, the segment shaft 1 is circular and composed of assembled caisson segments, and is arranged in the space below the ground. The floor slab 2 is sequentially arranged from top to bottom to divide the segment shaft 1 into several parking floors in the vertical direction. The multi-loop elevator system is arranged in the central area of the segment shaft 1, and the space it occupies is generally a cubic space.

[0045] As Figure 3 and 4 shown, the multi-loop elevator system is composed of two or four groups of circulating elevators 3. When the multi-loop elevator system is composed of two groups of circulating elevators 3, the two groups of circulating elevators 3 are arranged back-to-back as Figure 3 shown; when the multi-loop elevator system is composed of four groups of circulating elevators 3, the four groups of circulating elevators 3 are sequentially lapped to form a quadrilateral structure as Figure 4 shown. As Figure 3 shown, the multi-loop elevator system in this embodiment specifically adopts two groups of circulating elevators 3 arranged back-to-back. The following description will be made according to the two groups of circulating elevators 3 adopted.

[0046] As Figure 1-16 shown, each group of circulating elevators 3 includes two groups of sprockets 31, a track chain 32, a guiding mechanism 33, and a number of open carriages 34. The two groups of sprockets 31 are respectively arranged at the top and bottom of the space occupied by the circulating elevator 3, and the sprockets 31 are all driven by motors to rotate. The track chain 32 is correspondingly assembled on the two groups of sprockets 31 to form a circulating link. Under the drive of the sprockets 31, the track chain 32 can rotate around the two sprockets 31 in a cycle. One side of the track chain 32 is in an upward movement, and the other side of the track chain 32 is in a downward movement. A number of open carriages 34 are arranged at intervals on the track chain 32, and a guiding mechanism 33 is connected to the back of the open carriage 34. Through the setting of the guiding mechanism 33, it can be ensured that the open carriage 34 always maintains a vertical state during the rotation with the track chain 32, so as to prevent the vehicle loaded on it from tipping over.

[0047] As Figure 1-16As shown, the crawler chain 32 is composed of inner link sections 3202 and outer link sections 3203 arranged alternately in sequence. The inner link section 3202 includes two parallel inner link plates 3204 and two sets of roller assemblies 3205 arranged between the two inner link plates 3204. The roller assembly 3205 is composed of a sleeve and rollers sleeved outside the sleeve; the outer link section 3203 includes two parallel outer link plates 3206 and two sets of pin shafts 3201 arranged between the two outer link plates 3206. The outer link section 3203 is arranged between two adjacent inner link sections 3202, and the two pin shafts 3201 in the outer link section 3203 are respectively inserted into the sleeves of two adjacent inner link sections. At the installation position of the open car 34, one of the pin shafts 3201 in the outer link section 3203 protrudes from the outer link plate 3206, and relative rotation can occur between the pin shaft 3201 and the outer link plate 3206. The back surface of the vertical substrate 3401 in the open car 34 is fixedly connected to the end of the pin shaft 3201, and the other end of the pin shaft 3201 also protrudes from the outer link plate and is fixedly connected to the guiding mechanism 33.

[0048] As Figure 9 , 10 , as shown in FIG. 13, the open car 34 includes a vertical substrate 3401 and a plurality of load-bearing rods 3402 horizontally welded to the bottom of the front surface of the vertical substrate 3401. The load-bearing rods 3402 are spaced apart from each other to form a fence-like vehicle-carrying platform; when fixing the load-bearing rods 3402 to the vertical substrate 3401, sufficient bearing capacity when the vehicle is parked on it should be ensured. Therefore, slots can be preset on the vertical substrate 3401 in advance, and after inserting the load-bearing rods 3402 into the slots, welding fixation is carried out.

[0049] As Figure 1-16 shown, the guiding mechanism 33 is arranged on the back surface of the vertical substrate 3401 and guides the open car 34 to keep it in a vertical state all the time. The guiding mechanism 33 includes a cross guiding frame 3305 and a guiding substrate 3301. Among them, the central area of the cross guiding frame 3305 is fixedly connected to the end of the pin shaft 3201, and guiding columns are respectively arranged at the four end parts of the cross guiding frame 3305. As Figure 9 and 10As shown, the guiding substrate 3301 is vertically arranged and is composed of two substrates that are fitted together, namely a large substrate and another smaller substrate fitted on it. There are two sets of symmetric guiding grooves on the guiding substrate 3301 as a whole. One set of guiding grooves is used to guide the upward movement of the open car 34, and the other set of guiding grooves is used to guide the downward movement of the open car 34. That is, the two sets of guiding grooves are responsible for the entire cyclic rotation movement of the track chain 32 and the open car 34 thereon. Each set of guiding grooves includes a vertically centered central groove 3304 and two outer vertical side grooves 3302 and inner vertical side grooves 3303 arranged on both sides of the vertical central groove 3304. The vertical central groove 3304 is used to guide the guiding columns at the vertical two ends on the cross guiding frame 3305, and the outer vertical side groove 3302 and the inner vertical side groove 3303 are respectively used to guide the guiding columns at the horizontal two ends on the cross guiding frame 3305. Among them, the top of the outer vertical side groove 3302 also has an arc-shaped guiding groove to adapt to the turning of the open car 34 at the sprocket 31. The inner vertical side groove 3303 and the vertical central groove 3304 are opened on the guiding substrate 3301 and their depths reach the thicknesses of its two substrates. The inner vertical side groove 3303 and the vertical central groove 3304 are both linear and their lengths are between the two sprockets 31, while the outer vertical side groove 3302 is directly opened on the lower substrate, but it is in the combined form of a linear shape + an arc-shaped top.

[0050] As Figure 1 , 2 , 11, 12 shown, the movement track of the cross guiding frame 3305 behind the open car 34 is described as follows:

[0051] (S1) When the open car 34 moves in a pure vertical direction between the two sprockets 31, the guiding columns at the vertical two ends of the cross guiding frame 3305 move along the vertical central groove 3304, and the guiding columns at the horizontal two ends of the cross guiding frame 3305 move along the tracks of the outer vertical side groove 3302 and the inner vertical side groove 3303 respectively.

[0052] (S2) When the open car 34 moves to a position close to the sprocket 31, its movement track will move in an arc around the sprocket 31. That is, the guiding columns at the vertical two ends of the cross guiding frame 3305 gradually disengage from the vertical central groove 3304, and the guiding columns at the horizontal inner ends of the cross guiding frame 3305 also gradually disengage from the inner vertical side groove 3303, but the guiding columns at the horizontal outer ends of the cross guiding frame 3305 always move around the outer vertical side groove 3302.

[0053] (S3) After the open car 34 moves to the highest position above the sprocket 31, the guide posts on the original inner side in the horizontal direction of the cross guide frame 3305 become the guide posts on the outer side and enter the outer vertical side grooves 3302 of the other group for guiding. Thus, the guide posts at both vertical ends of the cross guide frame 3305 gradually enter the vertical central grooves 3304 of the other group, and the guide posts on the original outer side in the horizontal direction of the cross guide frame 3305 enter the inner vertical side grooves 3303 of the other group.

[0054] (S4) Based on steps S1 - S3, the open car 34 makes a cyclic rotational motion on the caterpillar chain 32.

[0055] As Figure 1-16 shown, the top layer of the segment shaft 1 on the ground is the top of two groups of loop elevators 3 arranged symmetrically back to back. A garage entrance and a garage exit are provided on the front of each group of loop elevators 3, and a translational extraction vehicle platform 4 is provided at both the garage entrance and the garage exit. As Figure 16 shown, a circular road 6 located within the ground area of the parking lot is provided around the top layer of the two groups of loop elevators 3. The periphery around the circular road 6 is the social road. Entrances and exits are provided at the four sides of the circular road 6, and the four groups of entrances and exits are respectively connected to the social road. At the same time, two two-way roads leading to the garage entrances and exits of the two groups of loop elevators 3 are provided on the circular road 6. Specifically, three of the four groups of entrances and exits are used as entrances (i.e., two entrances directly connected to the loop elevators 3 and the entrance on one side of the two loop elevators 3), and the remaining one is used as an exit. Vehicles drive into the circular road 6 from the social road through the aforementioned three entrances and drive into the garage entrance position through the incoming lane in the two-way road, waiting for the vehicle transfer chassis 5 and the translational extraction vehicle platform 4 to carry. When the vehicle is taken out of the vertical garage, it drives into the circular road 6 through the outgoing lane in the two-way road and exits to the social road through the exit.

[0056] In addition, a parking floor entrance and a parking floor exit are respectively provided in front of the loop elevators 3 on the ground of each parking floor. That is, as 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.

[0057] 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.

[0058] like Figure 1-16 As described above, the working method of the vertical garage with a multi-circulation elevator system in this embodiment includes the following steps:

[0059] (S1) According to the waiting situation for entering the warehouse on the ground, the vehicle enters the garage entrance in front of the corresponding circulation elevator 3 via the ring road 6 and stops. The vehicle transfer chassis 5 automatically drives under the chassis of the vehicle and supports 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.

[0060] (S2) The movable pickup 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 pickup vehicle platform 4 and lifts the vehicle transfer chassis 5 off the movable pickup vehicle platform 4 to sit on the open car 34. Then, the movable pickup 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.

[0061] After the open car 34 rotates around the sprocket 31 and reaches 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, control the grating platform 41 of the translational extraction vehicle platform 4 at the entrance of the parking floor to quickly translate outward onto the descending path of the open car 34. The open car 34 in the descending motion state passes through the gaps of the grating platform 41, and the vehicle transportation chassis 5 and the vehicle thereon are seated on the grating platform 41 of the translational extraction vehicle platform 4. Then, control the translational extraction vehicle platform 4 to retract to the ground of the parking floor. Then, automatically control the vehicle transportation chassis 5 to drive off the translational extraction vehicle platform 4 and automatically park in the empty parking space on this parking floor.

[0062] (S4)When the user needs to pick up the car, control the vehicle transportation chassis 5 to move under the chassis of the corresponding vehicle and transport it to the exit of this parking floor, and drive onto the translational extraction vehicle platform 4 at the exit of this parking floor. When the empty open car 34 rises close to this parking floor, control the translational extraction vehicle platform 4 to translate in advance onto the rising path of the open car 34. The open car 34 in the rising motion state passes through the gaps of the grating platform 41, and synchronously transfer the vehicle transportation chassis 5 and the vehicle thereon to 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, control the translational extraction vehicle platform 4 at the exit of the parking lot to extend outward onto the descending channel of the open car 34, and use the same method as in step S3 to enable the translational extraction vehicle platform 4 to extract the vehicle and the vehicle transportation chassis 5 on the open car 34. Then, control the translational extraction vehicle platform 4 to retract to the ground at the exit of the parking lot. The vehicle transportation chassis 5 transports the vehicle to the designated car pick-up position and then descends to separate from the vehicle, and finally facilitates the user to pick up the car and drive away.

[0063] The beneficial effects of this embodiment are as follows:

[0064] (1)Adopt a multi-loop elevator system. By setting the loop elevators back-to-back or overlapping each other to form a quadrilateral, parking floor entrances and exits can be set in at least two directions or four directions of the vertical underground garage, improving the car parking and pick-up efficiency of each parking floor;

[0065] (2)By adopting a loop elevator system in the circular vertical underground garage, multi-carriage vehicle transportation can be realized. Compared with the traditional single-carriage elevator system, the transportation capacity is effectively improved;

[0066] (3) By adopting an intermittent grid platform for the open car and the translational extraction vehicle platform, the open car can pass through the gaps between the grid platforms of the translational extraction vehicle platform during normal rotation, so as to transfer the vehicle transportation chassis and the vehicle onto or off the translational 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.
