The rotating shaft extends in the transverse direction.

[0103] In this embodiment, the guide position includes a first guide portion 111 formed on the top surface of the longitudinal beam 121, and the moving wheel 221 is correspondingly located on the first guide portion 111, and the moving wheel 221 moves along the first guide portion 111.

Among them, since the limiting wheel 222 is located on the lateral side of the longitudinal beam 121, at this time, the limiting wheels 222 of the two rows of moving wheel groups 22 can cooperate to limit the transfer rack 21 on the parking rack 1, and since the limiting wheels 222 of each moving wheel group 22 are located on the lateral side of the longitudinal beam 121, when the limiting wheel 222 moves along the second guide portion 112, the moving wheel 221 located on the top surface of the longitudinal beam 121 can keep moving along the first guide portion 111, so as to prevent the moving wheel group 22 from deviating from the established route and ensure the smooth movement of the transfer vehicle 2.

The guide position also includes a third guide portion formed on the bottom surface of the upper wing plate 1211, and the limiting portion 2222 is correspondingly located at the third guide portion and can move along the third guide portion. Since the upper wing plate 1211 is laterally outwardly beyond the web 1213, while the main body 2221 is attached to the lateral side of the upper wing plate 1211, the limiting portion 2222 can be attached to the bottom surface of the upper wing plate 1211 and can move along the bottom surface of the upper wing plate 1211.

[0108] In the above-mentioned limiting wheel 222, the design of the main body 2221 and the limiting portion 2222 enables the limiting wheel 222 to be simultaneously attached to two perpendicular surfaces and move along the two perpendicular surfaces, thereby enhancing the limiting effect of the limiting wheel 222, and further ensuring that the moving wheel 221 located on the top surface of the longitudinal beam 121 can continue to move along the first guide portion 111, so as to prevent the moving wheel group 22 from deviating from the established route and ensure the smooth movement of the transfer vehicle 2.

[0109] In this embodiment, the moving wheel set 22 includes two limiting wheels 222, which are arranged on both lateral sides of the moving wheel 221. Adaptively, the longitudinal beam 121 is formed with a second guide portion 112 matched with the main body 2221 and a third guide portion matched with the limiting portion 2222 on both lateral sides. That is, in actual application, the two limiting wheels 222 of each moving wheel set 22 are respectively attached to both lateral sides of the upper wing plate 1211 to limit the end frame 212 in the lateral direction, thereby ensuring the moving direction of the moving wheel 221.

[0110] In other embodiments, the moving wheel group 22 may also include only one limiting wheel 222. In this case, the limiting wheels 222 in the two rows of moving wheel groups 22 cooperate to limit the transfer rack 21 on the parking rack 1, so as to limit the transfer rack 21 laterally and enable the moving wheel 221 to keep moving in the longitudinal direction.

[0111] The cooperation between the moving wheel 221 and the first guide part 111 realizes the longitudinal guidance of the transfer vehicle 2, the cooperation between the limiting wheel 222 and the second guide part 112 realizes the lateral guidance of the transfer vehicle 2, and the cooperation between the limiting wheel 222 and the third guide part realizes the vertical guidance of the transfer vehicle 2. Therefore, guidance is achieved between the transfer vehicle 2 and the parking rack 1 in three directions, so that the transfer vehicle 2 can move better along the parking rack 1.

In this embodiment, the driving assembly 23 is directly arranged on the transfer frame 21, and is connected to the moving wheel set 22 located on the transfer frame 21. In this way, the transfer frame 21 can be directly driven to move by driving the moving wheel set 22 to rotate, so that the transfer vehicle 2 has the ability to walk by itself, which improves the integration degree of the self-propelled type. The assembly of the driving assembly 23 is relatively simple, and it is easy to maintain.

[0114] In this embodiment, the driving assembly 23 includes a driving wheel 232 , a driving chain 234 , a driven wheel 233 and a driving member 231 .

[0119] In actual application, the driving member 231 is started to rotate its output shaft to drive the active wheel 232 to rotate and drive the driving chain 234 to rotate. The driving chain 234 drives the driven wheel 233 to rotate during the rotation process. Since the driven wheel 233 and the moving wheel 221 are coaxially connected through the rotating shaft, the driven wheel 233 can drive the moving wheel 221 to rotate when it rotates.

[0120] In the present embodiment, the transfer vehicle 2 may further include a position detector 24, which is disposed on the transfer frame 21 and is used to detect the position information of the transfer vehicle 2. Exemplarily, the position detector 24 includes a toothed disc and a proximity switch. The toothed disc is sleeved on the rotating shaft and fixedly connected to the rotating shaft, that is, the toothed disc is coaxially connected to the driven wheel 233 and the moving wheel 221, so that the toothed disc can rotate with the driven wheel 233. The outer periphery of the toothed disc is serrated. The proximity switch is disposed on the lateral side of the end lower beam 2122 of the end frame 212, the proximity switch and the toothed disc are located on the same side of the end lower beam 2122, and the proximity switch is located on the lateral outer side of the toothed disc, and the proximity switch is connected to the control box 26 for communication. Among them, in the process of the chainring rotating with the driven wheel 233, the serrations of the chainring can pass through the proximity switch in sequence, and the proximity switch can detect the number of serrations of the chainring passing the proximity switch from the beginning of the rotation of the chainring, so as to obtain the longitudinal position information of the transfer vehicle 2 relative to the parking rack 1, and transmit the position information to the control box 26, so that the position of the transfer vehicle 2 can be located in real time, and the control box 26 can control and adjust the power of the driving member 231 to make the transfer vehicle 2 slow down or stop in place in advance.

The scraper includes two scraper plates 25, and the two scraper plates 25 are arranged on both longitudinal sides of the transfer frame 21, and a row of moving wheel groups 22 located at the same lateral end are distributed between the two scraper plates 25, so that when the transfer vehicle 2 moves relative to the parking frame 1, the scraper plates 25 can first contact with the parking frame 1, and scrape off impurities on the parking frame 1 as the transfer vehicle 2 moves, so as to prevent the impurities from contacting with the moving wheels 221 and hindering the movement of the moving wheels 221, thereby ensuring the smooth movement of the transfer vehicle 2.

Specifically, the number of sliders 41 is multiple, and the multiple sliders 41 are arranged at the upper end of the lifting frame 3 at intervals along the circumferential direction.

[0134] In this embodiment, the lifting frame 3 is further provided with a guide block 43, which is arranged one-to-one with the guide rail 16, and the guide block 43 slides with the corresponding guide rail 16 to achieve a sliding connection between the lifting frame 3 and the parking rack 1, so that during the conversion process between the low position state and the middle position state, the lifting frame 3 can slide along the guide rail 16 through the guide block 43, and can slide along the slide rail 42 through the slider 41, thereby improving the lifting stability of the lifting frame 3. Specifically, the number of the guide blocks 43 is multiple, and the multiple guide blocks 43 are arranged at the lower end of the lifting frame 3 at intervals along the circumferential direction.

[0135] The lifting frame 3 is driven by a power assembly to achieve lifting along the transfer frame 21. Exemplarily, a power assembly is provided on the transfer frame 21. The power assembly includes a power member 441, two gears arranged at intervals, and two connecting chains 442.

[0138] The two connecting chains 442 are arranged in one-to-one correspondence with the two gears, and one end of the connecting chain 442 is wound around the corresponding gear and extends downward to be connected to the lifting frame 3. In this embodiment, each connection point between the power component and the lifting frame 3 uses two connecting chains 442 to be simultaneously connected and fixed to the lifting frame 3, which improves the connection stability, thereby increasing the lifting force or pulling force of the power component on the lifting frame 3 to ensure the stability of the lifting frame 3 during lifting.

[0139] The power member 441 drives the two gears to rotate so that the two connecting chains 442 are wound around the corresponding gears or releases the connecting chains 442 so that the lifting frame 3 is lifted and lowered in the vertical direction.

[0140] There are multiple power components, which are distributed at intervals along the circumference of the transfer frame 21, and can balance the lifting force or pulling force on the lifting frame 3 to ensure the stability of the lifting frame 3 during lifting.

The rear comb tooth frame 33 is connected to the other end beam 353 through two connecting columns 352, and the connecting columns 352 extend in the vertical direction. At this time, a slider 41 is provided on the outer side of the upper end of each connecting column 352.

[0153] In this embodiment, the plate-filling comb frame 6 may further include a guide member 62, which is disposed on the outer side of the parking frame 1 in the lateral direction close to the entrance and exit 31. The top surface of the guide member 62 is inclined, and specifically, the top surface of the guide member 62 is inclined downward in a direction away from the parking frame 1 to make up for the height difference between the supporting surface and the first comb teeth of the lifting frame 3, so as to facilitate the vehicle to drive onto the lifting frame 3.

That is, when the wheel of the lifting frame 3 that first travels contacts the in-position detection component 71 during the process of the vehicle moving from the outside to the patch plate comb frame 6 and the lifting frame 3 to form a whole, the in-position detection component 71 can be triggered to detect the in-position signal of the vehicle.

[0163] The three-dimensional parking garage also includes a control panel, which is communicatively connected with the controller and is arranged outside the three-dimensional parking garage for users to operate outside the three-dimensional parking garage.

[0164] The working process of the above-mentioned three-dimensional parking garage is as follows:

[0165] Parking process:

[0166] The user indicates the need to park the car by operating the control panel. The controller controls the control box 26 to issue an instruction to control the transfer vehicle 2 to move the lifting frame 3 to the top of the parking rack 1. Then the lifting frame 3 is controlled to descend to a low position along the transfer rack 21. The controller controls the car hall door to rise to expose the entrance and exit 31. The user drives the vehicle into the lifting frame 3 through the entrance and exit 31. During this process, the weighing module detects the weight of the vehicle and feeds back the weight signal to the controller. If it exceeds the suitable parking weight, the controller sends an alarm signal to prompt the user to drive the vehicle out of the lifting frame 3. If the suitable parking weight is met, the user is prompted to get off the vehicle and leave the lifting frame 3, and then the car hall door is controlled to close the entrance and exit 31. The user confirms parking by operating the control panel. Then the size detector detects the length, width and height of the vehicle and feeds back the size information to the controller. The controller controls the power component to start and drives the lifting frame 3 to carry the vehicle along the transfer rack 21 to a high position. Then the control driving assembly 23 is started to drive the transfer vehicle 2 to move longitudinally to the parking space where no vehicle is parked, and the lifting frame 3 is controlled to descend to the middle position. At this time, the lifting frame 3 and the support frame 14 on the parking frame 1 perform comb teeth exchange, so that the vehicle can land on the support frame 14. Then the control driving assembly 23 drives the transfer vehicle 2 to move back to the top of the traffic opening, and controls the lifting frame 3 to descend to the low position to complete the parking action.

[0167] Pickup process:

[0168] The user indicates the need to pick up the vehicle by operating the control panel. The controller controls the power assembly to drive the lifting frame 3 to rise to the middle position. Then the controller controls the transfer vehicle 2 to drive the lifting frame 3 to move to the parking space of the vehicle to be picked up. The lifting frame 3 is controlled to rise to the high position. During this process, the lifting frame 3 and the support frame 14 of the parking frame 1 are exchanged with each other, so that the vehicle falls on the lifting frame 3. Then the transfer vehicle 2 is controlled to drive the lifting frame 3 and the vehicle on the lifting frame 3 back to the top of the traffic opening. Then the lifting frame 3 is controlled to descend to the low position, and the car hall door is controlled to open the exit, so that the user can enter the lifting frame 3 to drive the vehicle out. Then the car hall door is controlled to descend to close the entrance and exit 31 to complete the car picking action.
