Description

Technical Field

[0001] The invention relates to the field of garages, and in particular to a three-dimensional parking garage. Background Art

[0002] At present, with the continuous increase in the number of cars, the problem of parking difficulty has become increasingly prominent. Stereoscopic parking garages are widely used because of their small footprint and large number of parking spaces. For example, Chinese Patent No. 2015105427629 discloses a stereoscopic parking garage, which uses a chain to drive the carriage to move cyclically. Specifically, the upper and lower ends of the bracket are provided with chain plates, and the two chain plates are provided with chains, and the chains are provided with connecting plates extending outward. The frame is suspended on the connecting plates through a connecting rod, and one of the chain plates is driven to rotate by a motor, so that the frame can be driven to move cyclically by the chain. However, since the frame is installed on the connecting plate extending outward from the chain, the connecting plate will form a cantilever beam structure, and the frame will generate a large torque on the chain through the connecting plate, which will cause the chain to bear the lateral pressure in addition to the gravity generated by the frame. In this way, during actual operation, the running speed of the frame is slow, and since the chain is subjected to lateral force, it is also easy to deform and be worn and damaged, which reduces the service life and reliability. How to design a stereoscopic parking garage with high running speed, high service life and high reliability is a technical problem to be solved by the present invention. Summary of the invention

[0010] Furthermore, the guide column also includes two upper guide columns arranged on the vehicle carrying platform; the upper guide columns are located directly above the corresponding lower guide columns; and the inclined guide groove includes two inclined sub-guide grooves arranged in parallel and arranged up and down.

[0011] Furthermore, the number of teeth of the second sprocket meshing with the chain is not less than three.

[0012] Furthermore, at least one third sprocket is provided between the two second sprockets arranged up and down, and the driving mechanism is drivingly connected to the first sprocket, the second sprocket and the third sprocket respectively, and the first sprocket, the second sprocket and the third sprocket serve as power-driven active sprockets; a connecting shaft is provided between the two opposite active sprockets located at the same height on the two support frames; the driving mechanism is used to drive each of the active sprockets to operate synchronously, so that the load of the chain between the two adjacent active sprocket pairs above and below is borne by the active sprocket located above.

The friction between the guide column of the vehicle loading platform and the guide slide groove is small, so that the chain can drive the vehicle loading platform to run quickly and efficiently, thereby improving the operating efficiency of the three-dimensional parking garage, extending its service life and improving its reliability in use.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] See also Figure 1-Figure 7 As shown, the three-dimensional parking garage of this embodiment includes an installation frame 1, a plurality of vehicle loading platforms 2 and a driving mechanism 3, wherein the installation frame 1 includes two relatively arranged support frames 11, the top and bottom of the support frame 11 are respectively provided with a first sprocket 41, and the two sides of the support frame 11 are respectively provided with two second sprockets 42 arranged up and down, and the first sprocket 41 and the second sprocket 42 on the same support frame 11 are provided with a chain 5, and a hinge 51 is formed between two adjacent links in the chain 5, and a suspension link 22 is provided on the upper part of the vehicle loading platform 2, and one end of the suspension link 22 is connected to the hinge 51 of one of the chains 5, and the other end of the suspension link 22 is connected to the corresponding hinge 51 of the other chain 5; a guide slot 6 is provided on at least one of the support frames 11, and a guide column 24 is provided on the vehicle loading platform 2, and the guide column 24 is slidably arranged in the guide slot 6; the driving mechanism 3 drives the first sprocket 41 and / or the second sprocket 42 to rotate.

[0028] Specifically, in the three-dimensional parking garage of this embodiment, two relatively arranged support frames 11 are installed on the foundation 100, and a plurality of sprockets are arranged on the support frames 11 to install the chains 5. The installation positions of the corresponding sprockets on the two support frames 11 are the same. The driving mechanism drives the sprockets to rotate to drive the two chains 5 to rotate synchronously, wherein the sprocket connected to the driving mechanism is used as the driving sprocket, and the sprocket not connected to the driving mechanism is used as the driven sprocket, and the two corresponding driving sprockets on the two support frames 11 are connected by a connecting shaft to ensure that the two driving sprockets rotate synchronously and the two chains 5 run synchronously, and the driven sprockets can be connected by the corresponding connecting shaft as needed, and the driven sprockets can also be independent of each other without the connecting shaft to reduce the manufacturing cost. The following is an example of the first sprocket 41 at the bottom of the support frame 11 driven by the driving mechanism 3. The driving mechanism 3 transmits power to the first sprocket 41 at the bottom of the support frame 11. The first sprockets 41 at the bottom of the two support frames 11 are connected by a connecting shaft to rotate synchronously. The rotation of the first sprocket 41 at the bottom will drive the two chains 5 to run synchronously, thereby driving the vehicle loading platform 2 on the chain 5 to follow the movement, wherein the vehicle loading platform 2 is connected to the corresponding hinged parts 51 of the two chains 5 through the suspension link 22. In this way, the force generated by the vehicle loading platform 2 on the chain 5 acts on the hinged part 51. During the movement of the chain 5, the vehicle loading platform 2 can rotate relative to the hinged part 51, thereby ensuring that the vehicle loading platform 2 always remains in an upright state, and through the guidance of the guide column 24 on the vehicle loading platform 2 and the guide slide groove 6 on the support frame 11, it is ensured that the vehicle loading platform 2 can move along the guide slide groove 6, thereby reducing the shaking of the vehicle loading platform 2 during the movement of the chain 5. Since the suspension link 22 of the vehicle loading platform 2 is connected to the hinge 51 of the chain 5, there is no need to configure an additional extending connecting plate on the chain 5 to install the vehicle loading platform 2; the vehicle loading platform 2 will generate a vertical downward pulling force on the hinge 51 under the action of gravity, so that the chain 5 is subjected to a downward pulling force at the hinge 51, and the chain link part of the chain 5 will not be subjected to a lateral force perpendicular to the chain link direction, especially for the part of the chain 5 running in a vertical state, so that the vehicle loading platform 2 will not generate a torque on the chain 5 to cause the chain 5 to twist. Thereby, the wear of the chain 5 during operation can be reduced. At the same time, compared with the prior art that adopts a cantilever beam structure to install the frame on the connecting plate, a guide groove is required on one side of the chain to assist in bearing the gravity of the frame. Since the suspension link 22 of the vehicle loading platform 2 is connected to the hinge part 51 of the chain 5, the guide groove 6 mainly plays a guiding role during actual use, and the friction between the guide column 24 and the guide groove 6 is small, so that the vehicle loading platform 2 can move quickly along the guide groove 6 to improve the operation efficiency.Among them, in order to facilitate the installation of the suspension link 22, the hinged part 51 connecting the chain 5 and the suspension link 22 is a bushing, and the end of the suspension link 22 is inserted into the bushing. In order to reduce the friction between the suspension link 22 and the hinged part 51, a wear-resistant sleeve is also provided in the bushing, and the end of the suspension link 22 is inserted into the wear-resistant sleeve.

[0029] Further, the guide slide 6 includes two vertical guide grooves 61 arranged on the left and right, and the ends of the vertical guide grooves 61 are respectively provided with inclined guide grooves 611, the inclined guide groove 611 located at the upper part extends upward, and the inclined guide groove 611 located at the lower part extends downward; the vertical guide groove 61 and the inclined guide groove 611 are arranged on the support frame 11. Specifically, according to the distribution of the sprockets on the support frame 11, when the chain 5 drives the vehicle-carrying platform 2 to move in a circular manner, when it moves in the vertical direction between the two second sprockets 42 arranged adjacent to each other, the vehicle-carrying platform 2 is guided and moved through the vertical guide grooves 61, and when it moves between the first sprocket 41 and the second sprocket 42 arranged adjacent to each other, the vehicle-carrying platform 2 is guided and moved through the inclined guide grooves 611 at the ends of the vertical guide grooves 61, so as to ensure the smooth operation of the vehicle-carrying platform 2. Preferably, since the vehicle loading platform 2 will be located in the vehicle entry and exit area at the bottom of the mounting frame 1 when parking and picking up the vehicle, and since the moving vehicle will cause the vehicle loading platform 2 to shake when the vehicle enters or exits the vehicle loading platform 2, in order to ensure that the vehicle loading platform 2 still obtains good guiding support during the parking and picking up process, the guide slide groove 6 also includes a transverse guide groove 62, which is arranged at the bottom of the support frame 11 and is located between the two inclined guide grooves 611 at the bottom; the guide column 24 includes a guide column 24 arranged at the vehicle loading platform Specifically, when the vehicle loading platform 2 moves to the vehicle entry and exit area at the bottom, the two lower guide columns 241 at the bottom of the vehicle loading platform 2 are located in the transverse guide groove 62. On the one hand, the transverse guide groove 62 can guide the vehicle loading platform 2 in the process of moving the vehicle loading platform 2 to the bottom. On the other hand, in the process of parking and picking up the vehicle, the lower guide columns 241 cooperate with the transverse guide groove 62 to reduce the shaking of the vehicle loading platform 2. Under the restriction of the transverse guide groove 62, the two lower guide columns 241 reduce the shaking room of the vehicle loading platform 2. Among them, in order to ensure that the vehicle loading platform 2 obtains good guidance when moving between the first sprocket 41 and the second sprocket 42, the guide column 24 also includes two upper guide columns 242 arranged on the vehicle loading platform 2; the upper guide columns 242 are located directly above the corresponding lower guide columns 241; the inclined guide groove 611 includes two parallel inclined sub-guide grooves 6111 arranged up and down. Specifically, for the inclined guide groove 611 on the vertical guide groove 61, the upper inclined sub-guide groove 6111 is used to cooperate with the upper guide column 242 for guidance, and the lower inclined sub-guide groove 6111 is used to cooperate with the lower guide column 241 for guidance.In addition, in order to further ensure that the chain 5 can cooperate with the sprocket to drive the vehicle loading platform 2 to move smoothly, the number of teeth meshing between the second sprocket 42 and the chain 5 is not less than three. Specifically, since the second sprocket 42 is distributed at the four corners of the mounting frame 1, the chain 5 will change direction of its moving trajectory when passing through the second sprocket 42. By increasing the number of teeth meshing between the second sprocket 42 and the chain 5, the vehicle loading platform 2 can change its motion trajectory more smoothly when moving to the second sprocket 42, thereby reducing the shaking degree of the vehicle loading platform 2, reducing the impact on the guide slot 6, and further improving the operating efficiency.

[0030] At the same time, in order to more reliably improve the stability of the vehicle loading platform 2 during the process of parking and picking up the vehicle while reducing the impact on the chain 5, a positioning support assembly is also provided on the foundation 100, and the positioning support assembly is used to position and support the vehicle loading platform 2 located at the vehicle entry and exit area. Specifically, during the process of parking and picking up the vehicle, the vehicle loading platform 2 will move to the vehicle entry and exit area at the bottom of the mounting frame 1. At this time, the vehicle loading platform 2 in the vehicle entry and exit area can be supported and positioned by the positioning support assembly. On the one hand, the vehicle loading platform 2 can be supported from the bottom, and on the other hand, the positioning support assembly can also position the side of the vehicle loading platform 2. In this way, during the process of parking and picking up the vehicle, it can ensure that the vehicle loading platform 2 remains stable, and at the same time, the impact on the chain 5 caused by a sudden change in the load of the vehicle loading platform 2 when the car enters or exits can be reduced. The positioning support assembly includes a plurality of positioning telescopic modules 7, the positioning telescopic modules 7 include a telescopic mechanism 71 and a positioning support 72 arranged on the telescopic mechanism 71, the positioning support 72 has a supporting portion for supporting the bottom of the vehicle loading platform 2, and the positioning support 72 also has a positioning portion for positioning the side of the vehicle loading platform 2. Specifically, the positioning support 72 can be moved closer to or away from the vehicle loading platform 2 by telescoping the telescopic mechanism 71. When parking or picking up a vehicle, the telescopic mechanism 71 drives the positioning support 72 to move closer to the vehicle loading platform 2, the supporting portion of the positioning support 72 will support the vehicle loading platform 2 from the bottom, and the positioning portion of the positioning support 72 will position the vehicle loading platform 2 from the side; and the telescopic mechanism 71 can be represented by a telescopic electromagnet, an electric cylinder, a linear motor, etc. The positioning support 72 can be a positioning support plate with an L-shaped cross section, the transverse plate surface of the positioning support plate forms the supporting portion, and the longitudinal plate surface of the positioning support plate forms the positioning portion. In addition, the telescopic mechanism 71 can be arranged horizontally on the foundation 100, and the telescopic mechanism 71 arranged horizontally can be telescopic in the horizontal direction; or, the telescopic mechanism 71 can be arranged longitudinally on the foundation 100, and the telescopic mechanism 71 arranged longitudinally can be telescopic in the vertical direction. Preferably, the positioning telescopic modules 7 are arranged at both ends and both sides of the vehicle loading platform 2 located at the vehicle entry and exit area on the foundation 100. Specifically, the vehicle loading platform 2 located at the vehicle entry and exit area forms a projection area on the foundation 100, and correspondingly, positioning telescopic modules 7 are arranged around the projection area, and the positioning telescopic modules 7 arranged around the vehicle loading platform 2 can be positioned and supported around.

[0031] Furthermore, the vehicle loading platform 2 includes a vehicle loading plate 21, a connecting frame 23 and a suspension link 22, and the front and rear ends of the vehicle loading plate 21 are respectively provided with connecting frames 23, and the suspension link 22 is connected to the two connecting frames 23, and the connecting frame 23 is an inverted U-shaped structure. Specifically, the vehicle loading plate 21 is installed on the suspension link 22 through the connecting frame 23 of the inverted U-shaped structure. The vehicle loading plate 21 is used to park the car. In order to ensure that the car can be parked accurately, guide grooves 211 for guiding the movement of the wheels are formed on both sides of the vehicle loading plate 21. Specifically, when parking, the user drives the wheels on both sides into the corresponding guide grooves 211, and the car moves along the guide grooves 211 to the vehicle loading plate 21. At the same time, a limiting lever 212 for limiting the movement of the wheels is also provided in the guide groove 211. When the wheels of the car abut against the limiting lever 212, it means that the car is parked in place, so as to ensure that the position of the car on the vehicle loading plate 21 is accurate and the force on the vehicle loading plate 21 is balanced. The two connecting frames 23 extend downwardly from top to bottom in an inclined manner toward the middle of the vehicle-carrying plate 21, and the connecting frames 23 form an inclined-pull structure, which is conducive to more reliable installation of the vehicle-carrying plate 21 on the suspension link 22 through the connecting frames 23. Bearings are provided on the connecting frames 23, and the ends of the suspension link 22 pass through the corresponding bearings on the connecting frames 23. The vehicle-carrying plate 21 and the connecting frames 23 can be fixed together by bolts or welding, and the vehicle-carrying plate 21 can be rotatably hung on the suspension link 22 through the connecting frames 23. At the same time, the suspension link 22 can rotate relative to the hinge 51 of the chain 5, and two rotating pairs are formed between the vehicle-carrying plate 21 and the chain 5 to ensure that the vehicle-carrying plate 21 remains horizontal during movement. In addition, for the guide column 24, the lower guide column 241 is set on the vehicle loading plate 21, and the upper guide column 242 is set on the connecting frame 23. In order to further reduce the friction between the guide column 24 and the guide groove 6, the lower guide column 241 and the upper guide column 242 are respectively provided with rollers, and the rollers are used to roll in the guide groove 6.

[0032] Furthermore, in order to facilitate the adjustment of the tightness of the chain 5 and reduce the difficulty of installation, a lifting bracket 8 that can be raised and lowered is provided on the top of the support frame 11, and the first sprocket 41 located at the top is installed on the lifting bracket 8. Specifically, by installing the first sprocket 41 on the top of the support frame 11 to the lifting bracket, during the assembly process, after the chain 5 is connected to the first sprocket 41 and the second sprocket 42, the lifting bracket is raised to make the chain 5 reach a tensioned state, so that there is no need to add an additional tensioning wheel, and the use of a tensioning wheel can also avoid the shape of the chain 5 protruding outward or concave inward. In this way, the overall direction of the chain 5 is smoother, thereby ensuring that the vehicle-carrying platform 2 can follow the smooth movement of the chain 5. Among them, the specific entity of the lifting bracket 8 has a variety of structural forms, and the lifting bracket 8 includes a supporting beam 81, a mounting seat 82 and a lifting component 83. The supporting beam 81 is fixed on the supporting frame 11, and the mounting seat 82 is installed on the supporting beam 81 through the lifting component 83. The first sprocket 41 located at the top is installed on the mounting seat 82. Specifically, the supporting beam 81 is fixed to the supporting frame 11 as a supporting component, and a bearing seat 821 is arranged on the mounting seat 82 for installing the first sprocket 41, and the height position of the mounting seat 82 is adjusted by adjusting the lifting component 83. The specific entity of the lifting component 83 has a variety of structural forms, for example: the lifting component includes a plurality of supporting longitudinal beams 831, and a plurality of longitudinally arranged first mounting holes (not marked) are provided on the supporting beam 81. The lower end of the supporting longitudinal beam 831 is provided with a locking bolt (not marked), and the locking bolt is inserted into In the first mounting hole at the corresponding height position, the mounting seat 82 is fixed to the upper end of the supporting longitudinal beam 831. During actual assembly, after the chain 5 is installed, the supporting longitudinal beam 831 is raised to make the chain 5 reach a tightened state, and then, the locking bolt is inserted into the first mounting hole at the corresponding height position for fixing; or, the lifting assembly 83 includes a plurality of telescopically adjustable columns 832, and the columns 832 are arranged between the supporting cross beam 81 and the mounting seat 82. Specifically, the columns 832 can be a telescopic rod structure, and the columns 832 include a fixed column and a sliding column, and the sliding column can slide on the fixed column. A locking component is arranged between the fixed column and the sliding column, and the locking component can be a latch, and correspondingly, the fixed column and the sliding column are respectively provided with a plurality of latch holes. After the sliding column is adjusted into place, the latch is inserted into the latch hole of the fixed column and the latch hole of the sliding column at the same time. In the process of adjusting the supporting longitudinal beam 831 or the telescopic column 832, a jack can be used to support the mounting seat 82 on the supporting crossbeam 81 and gradually raise the mounting seat 82 until the chain 5 is tightened, and then the supporting longitudinal beam 831 or the column 832 is fixed and locked accordingly.In addition, after the lifting assembly 83 adjusts the height position of the mounting seat 82, in order to fix the mounting seat 82, a plurality of longitudinally arranged second mounting holes can be correspondingly set on the support frame 11, and the two ends of the mounting seat 82 are fixed by inserting fixing bolts into the second mounting holes at the corresponding height positions.

[0033] By connecting the suspension link on the vehicle loading platform to the hinge part of the corresponding chain, no force arm is formed between the suspension link and the hinge part. In this way, the chain only bears the downward pulling force generated by the vehicle loading platform, and the vehicle loading platform will not generate additional torque on the chain part running in the vertical state. On the one hand, it ensures that the chain part running in the vertical state will not be deformed by the lateral force, thereby reducing the wear of the chain and increasing the service life of the chain. On the other hand, the vehicle loading platform only generates a downward pulling force on the chain without generating torque, so that the guide slide groove only needs to guide the running vehicle loading platform without providing supporting force. The friction between the guide column of the vehicle loading platform and the guide slide groove is small, so that the chain drives the vehicle loading platform to run quickly and efficiently, thereby improving the operating efficiency of the three-dimensional parking garage, extending its service life and improving its reliability.

[0034] Based on the above technical solution, optional, such as Figure 8-Figure 9As shown, in order to reduce the operating energy consumption and make full use of the height space to obtain more parking spaces, the mounting frame 1 can be increased in the height direction. Correspondingly, the length of the chain 5 will increase. At the same time, the number of vehicle loading platforms 2 suspended on the chain 5 will increase at the same time, and the chain 5 will cumulatively bear the tension generated by multiple vehicle loading platforms 2. In order to improve the reliability of the chain 5, the chain 5 carries the vehicle loading platform 2 in a segmented load-bearing manner. Specifically, at least one third sprocket 43 is also arranged between the two second sprockets 42 arranged up and down, and the driving mechanism 3 is respectively connected to the first sprocket 41, the second sprocket 42 and the third sprocket 43. The first sprocket 41, the second sprocket 42 and the third sprocket 43 are used as driving sprockets with power drive; the two supporting frames 11 are located at the same height position, and a connecting shaft is arranged between the two opposite driving sprockets; the driving mechanism 3 is used to drive each of the driving sprockets to operate synchronously, so that the two adjacent driving sprocket pairs above and below are borne by the driving sprocket located above. The load of the chain 5 between the two adjacent driving sprockets. Specifically, two driving sprockets connected by a connecting shaft form a group of driving wheel pairs, and the driving mechanism 3 provides power for each driving wheel pair, so that the driving sprocket in the driving wheel pair can provide pulling force to the chain 5 below it. By controlling the driving force of the driving wheel pair at different positions, the following effects can be achieved: for the two driving sprockets adjacent to each other in the same support frame, the driving sprocket located above is configured to bear the load of the chain 5 between the two driving sprockets, thereby realizing the segmented load-bearing of the chain 5, wherein the driving mechanism 3 has multiple ways of transmitting power to the driving wheel pairs respectively. For example, in the first scheme, the driving mechanism 3 includes a main motor and a power distribution box 31, wherein the power distribution box 31 is provided with a power input shaft and a plurality of power output shafts connected to the power input shaft, wherein the main motor is connected to the power input shaft, and the power output shaft is connected to the corresponding driving wheel pair, thereby realizing synchronous operation and bearing the load of the chain in sections; or, in the second scheme, the driving mechanism 3 includes a plurality of driving motors connected to the driving wheel pair, realizing synchronous operation or automatic acceleration or deceleration operation according to the load between the two driving sprockets through a control system, thereby bearing the load of the chain in sections. In addition, according to the length of the chain 5 between two adjacent driving sprockets, in the case where the chain 5 between the two driving sprockets is relatively long, a driven sprocket (not shown) can also be provided between the upper and lower adjacent driving sprockets, and the chain 5 is guided by the driven sprocket to ensure that the chain 5 can move smoothly, wherein the driven sprocket is driven as a driven wheel without power and is only used to guide the chain 5.Preferably, due to the different storage states of the vehicles in the vehicle loading platform 2 at different positions, the different numbers of stored vehicles lead to unbalanced load. In order to ensure smooth movement during actual operation, the driving wheel pair also includes a speed limiting component, which includes a friction sleeve 431, a mounting shaft 432 and a plurality of friction plates 433. The mounting shaft 432 is inserted into the friction sleeve 431, and a plurality of guide rods 435 are arranged on the periphery of the mounting shaft 432. The outer surface of the friction plate 433 is arranged to be an arc surface that cooperates with the inner wall of the friction sleeve 431. The friction plate 433 is slidably arranged on the corresponding guide rod 435, and a return spring 434 is arranged between the friction plate 433 and the mounting shaft 432; the friction sleeve 431 is fixedly arranged on the mounting frame, and the mounting shaft 432 is connected to the driving sprocket. Specifically, when the driving sprocket rotates, it will also drive the mounting shaft 432 to rotate. The friction plate 433 will overcome the pulling force of the return spring 434 and move outward under the action of centrifugal force. When the rotation speed of the driving sprocket exceeds the set value, the friction plate 433 will contact the inner wall of the friction sleeve 431 to generate friction. Moreover, the greater the rotation speed of the driving sprocket, the greater the friction generated. This can effectively stabilize the rotation speed of the driving sprocket and avoid the occurrence of overspeeding of the driving sprocket when the weight distribution is unbalanced, thereby ensuring that the entire equipment can run smoothly.

[0035] Furthermore, the driving wheel pair also includes a brake (not shown) for braking the driving sprocket; the three-dimensional parking garage also includes a position sensor for detecting the position of the vehicle loading platform 2. Specifically, when the position sensor requires the vehicle loading platform to stop at a specified position, the brake will brake the driving wheel pair to ensure that the driving sprocket will not rotate arbitrarily without power, ensuring the static state in the parking state. Preferably, the driving wheel pair is also provided with a torque sensor (not shown) for detecting the torque magnitude of the driving sprocket; at the same time, each vehicle loading platform 2 is provided with a weighing sensor (not shown). Specifically, in order to realize that the driving sprocket provides segmented pulling force to the chain 5 below it until the next driving sprocket, so as to realize the segmented load-bearing of the chain more accurately, for the vehicle-carrying platform 2 at different positions, there are two states: with a vehicle and without a vehicle. The number of vehicle-carrying platforms 2 that can be placed on the chain 5 between the two upper and lower adjacent driving sprockets is certain. The weight carried by the vehicle-carrying platform 2 on the chain 5 between the two upper and lower adjacent driving sprockets can be obtained through the weighing sensor when the vehicle is parked on the vehicle-carrying platform and stored in the control system for computer call. Combined with the weight of the chain 5 and the vehicle-carrying platform 2 itself, it can be accurately calculated. The torque generated by the section of chain 5 and the corresponding vehicle-carrying platform 2 on the upper driving sprocket is obtained. In this way, in the process of the driving mechanism 3 driving the chain to circulate, on the ascending side, when the torque value detected by the torque sensor corresponding to the upper driving sprocket is greater than the calculated torque value, the lower driving sprocket will accelerate to increase the load-bearing capacity; on the descending side, when the torque value detected by the torque sensor corresponding to the upper driving sprocket is greater than the calculated torque value, the lower driving sprocket will decelerate to increase the load-bearing capacity. In this way, the driving sprocket bears the load of the corresponding part of the chain 5 below it, and the segmented load-bearing is realized more accurately.

[0036] The present invention also provides a control method for the above-mentioned three-dimensional parking garage, the control method comprising: a driving mechanism drives each driving wheel pair to rotate synchronously, so that the driving wheel pair located above the two adjacent driving wheel pairs bears the load of the chain between the two driving wheel pairs. Specifically: by driving each driving wheel pair to rotate synchronously, the driving wheel pair located above bears the load of the corresponding chain part below it, eliminating the cumulative effect of the chain load, effectively enhancing the load-bearing capacity of the chain, making it very easy to build a single large-capacity three-dimensional parking garage, reducing the operating energy consumption and manufacturing cost of the three-dimensional parking garage, and greatly improving the operating speed and shortening the time for storing and retrieving cars. Among them, during the chain circulation process, for the two adjacent driving wheel pairs on the rising side, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is greater than the load of the chain between the two driving wheel pairs, the lower driving wheel is accelerated accordingly until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs; conversely, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is less than the load of the chain between the two driving wheel pairs, the upper driving wheel is accelerated accordingly until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs. load; for the two adjacent driving wheel pairs on the descending side, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is greater than the load of the chain between the two driving wheel pairs, the lower driving wheel will decelerate and increase the load-bearing until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs; conversely, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is less than the load of the chain between the two driving wheel pairs, the upper driving wheel will decelerate and increase the load-bearing until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs.

[0037] For the driving method using scheme one, a main motor drives each driving wheel pair to rotate synchronously through a power distribution box, so that the upper driving wheel pair can bear the load of the corresponding chain part below it; and for the driving method using scheme two, since the driving wheel pairs are driven by different driving motors, the output power of the driving motor can be dynamically controlled. For the two adjacent driving wheels on the upper and lower sides of the ascending side, when the torque value detected by the torque sensor corresponding to the upper driving wheel is greater than the load of the chain between the two driving wheels, the lower driving wheel is accelerated accordingly until the torque value detected by the torque sensor corresponding to the upper driving wheel is equal to the load of the chain between the two driving wheels; conversely, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is less than the load of the chain between the two driving wheel pairs, When the load is heavy, the upper driving wheel is accelerated accordingly until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs; and for the two adjacent driving wheel pairs on the descending side, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is greater than the load of the chain between the two driving wheel pairs, the lower driving wheel is decelerated and increased in load-bearing until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs; conversely, when the torque value detected by the torque sensor corresponding to the upper driving wheel pair is less than the load of the chain between the two driving wheel pairs, the upper driving wheel is decelerated and increased in load-bearing until the torque value detected by the torque sensor corresponding to the upper driving wheel pair is equal to the load of the chain between the two driving wheel pairs.

[0038] Compared with the prior art, the present invention has many advantages and positive effects: the driving mechanism can drive the driving sprockets in each driving wheel pair to rotate synchronously, so that each driving sprocket can have power during operation. For two adjacent driving sprockets, the upper driving sprocket can bear the load of the chain between the upper and lower driving wheel pairs, and the maximum load of each section of the chain between the upper and lower driving wheel pairs will not exceed the load of the chain section. In this way, the chain can be loaded in sections, which effectively reduces the maximum load coefficient of the chain. Therefore, when selecting the chain specifications and dimensions, the specifications and dimensions can be effectively reduced, and the number of parking spaces in the three-dimensional parking garage can be effectively increased, thereby reducing manufacturing costs and operating energy consumption, and enhancing carrying capacity.
