[0002] With the acceleration of urbanization, the rapid growth of car ownership has made parking a severe challenge faced by major cities. Mechanical three-dimensional parking garages have gradually become an effective means to alleviate the problem of parking difficulties with their advantages of small footprint, convenient installation and relatively low cost. Vertical lifting parking equipment, as an important type of mechanical three-dimensional parking garage, is widely used for its simple structure, small footprint and flexible installation. However, traditional vertical lifting parking equipment generally adopts a single access port design, which leads to vehicles waiting in line during peak hours and low access efficiency, especially when the traffic volume is large.

[0023] Embodiment 1 This embodiment provides a shaft-type underground parking garage, such as Figure 1 As shown, the parking garage is divided into two parking areas 1 and a parking pick-up area 2; like Figure 2 As shown, the parking area 1 is composed of a top parking area 3, a ground parking area 4 and an underground parking area 5 from top to bottom in the vertical direction. A shock-absorbing track device 6 is arranged on the side wall of the parking area 1. The shock-absorbing track device 6 is arranged in combination with the external maintenance structure of the parking area 1. A movable parking plate 7 is arranged in the parking area 1. The car picking area 2 includes an elevator, and the elevator includes a carrier 8 and a scissor arm 9. The scissor arm 9 is arranged at the bottom of the car picking area 2, and the top of the scissor arm 9 is connected to the carrier 8. The shock-absorbing track device 6 includes a shock-absorbing base and a lifting guide rail. The shock-absorbing base is installed on the external maintenance structure. The lifting guide rail is arranged on the shock-absorbing base, and the lifting guide rail is docked with the rotatable pulley device 7-6.

[0024] like Figure 3 As shown, the movable parking board 7 includes a rotatable telescopic arm 7-1, a vehicle parking board 7-2, a slide rail 7-3, a distance sensor 7-4, a sensor alarm device 7-5 and a rotatable pulley device 7-6; four rotatable telescopic arms 7-1 are arranged on the side of the movable parking board 7, one end of the rotatable telescopic arm 7-1 is fixed to the side of the movable parking board 7 through a rotating shaft, and can achieve 90-degree rotation around the axis of the rotating shaft, so that the rotatable telescopic arm 7-1 can rotate from a position parallel to the movable parking board 7 to a position perpendicular to the movable parking board 7, and the height of the rotatable telescopic arm 7-1 is adjusted with the height of the vehicle. The vehicle parking board 7-2 is arranged on the top surface of the movable parking board 7, and the slide rail 7-3 is arranged on the bottom surface of the movable parking board 7, and the slide rail can cooperate with the carrier 8 to facilitate the movement of the carrier. The distance sensor 7-4 is arranged on the bottom surface of the movable parking plate 7, which can detect the distance between the bottom surface of the movable parking plate 7 and the vehicle below, and can adjust the length of the rotatable telescopic arm 7-1, so as to realize flexible and controllable parking space height. The sensor alarm device 7-5 adopts a temperature sensor alarm and a smoke sensor alarm, which can give an early warning in the event of a disaster and send a signal to the main control room. The main control room controls the transporter 8 to the alarm parking space for rescue. For example, if the vehicle smokes, the sensor of the upper parking space will send a signal, and the vehicle picker will reach the height of the upper parking space and start to lift the parking space at that height and above to the ground. The rotatable pulley device 7-6 is hinged at one end of the movable parking plate 7. The rotatable pulley device 7-6 includes a plurality of pulleys and a fixed shaft. The fixed shaft fixes the plurality of pulleys on the same horizontal line, and the fixed shaft is hinged at one end of the movable parking plate 7. The rotatable pulley device 7-6 is arranged at one end of the movable parking board 7 and cooperates with the shock-absorbing track device 6 to work. The rotatable pulley device 7-6 can rotate up to 180 degrees with one end of the movable parking board 7 as the symmetry axis. When in the ground parking area 4, the rotatable pulley device 7-6 rotates to the bottom of the movable parking board 7 and will not hinder the vehicle from entering the movable parking board 7; when in the top parking area 3, the rotatable pulley device 7-6 rotates to the top of the movable parking board 7, saving storage space in the top parking area 3.

[0025] like Figure 4As shown, the movable parking board 7 has three states. State 1: When in the top parking board area 3, the rotatable telescopic arm 7-1 rotates to the two sides of the vehicle parking board 7-2 and the rotatable pulley device 7-6 rotates to the top of the vehicle parking board 7-2. The movable parking board 7 is also in this state when it is located on the carrier 8. State 2: When in the ground parking area 4, the rotatable telescopic arm 7-1 rotates 90 degrees, and its direction is perpendicular to the movable parking board 7, and it has the ability to withstand vertical pressure. The rotatable telescopic arm 7-1 is fixedly supported on another movable parking board 7 below after adjusting its length according to the height of the vehicle below, and the rotatable pulley device 7-6 rotates to the bottom of the vehicle parking board 7-2. State 3: In the underground parking area 5, the rotatable pulley device 7-6 is combined with the shock-absorbing track device 6, and the vehicle sliding speed is controlled in cooperation with the shock-absorbing track device 6 under the action of gravity until the movable parking board 7 slides down to the lowest level and the parking is completed.

[0026] like Figure 5 As shown, the carrier 8 is provided with a sliding grab plate 8-1 and a motor box 8-2. The sliding grab plate 8-1 is provided with a slider. When moving, the slider moves through the slide rail 7-3 on the movable parking plate 7, thereby reducing the friction of the sliding grab plate 8-1 moving under the movable parking plate. The sliding grab plate 8-1 is provided with a mechanical locking mechanism. When the sliding grab plate 8-1 moves to a suitable position under the movable parking plate 7, the two are fixed by the mechanical locking mechanism. The motor box 8-2 provides power for the sliding grab plate 8-1. A receiver is provided inside the motor box 8-2. When the sensor alarm device 7-5 of the movable parking plate 7 alarms, the main control room receives the alarm signal and controls the carrier 8 to reach the alarm area through the motor box 8-2.

[0027] like Figure 6 As shown, the sliding grab plates 8-1 on the carrier 8 are divided into two groups, each group is used for two different parking areas 1. State 1: When the carrier 8 moves vertically normally, the sliding grab plates 8-1 are retracted to the middle of the carrier 8. State 2: When the movable parking plate 7 on one side is moved, a group of sliding grab plates 8-1 on the same side is translated to the bottom of the movable parking plate 7 and fixed, and then the sliding grab plates 8-1 drive the movable parking plate 7 to move onto the carrier 8. At this time, the rotatable telescopic arms 7-1 are retracted to both sides of the vehicle parking plate 7-2; in addition, when the movable parking plate 7 triggers the sensor alarm device 7-5, the sliding grab plates 8-1 move to the bottom of the movable parking plate 7 that triggers the alarm and is fixed. At this time, the scissor arms 9 are lifted, and at the same time drive the sliding grab plates 8-1 to lift the upper movable parking plate 7 and its vehicles, reducing the risk of damage to the upper vehicles. State three: A water level alarm is installed at the bottom of the underground parking garage. When the water level alarm is triggered, two sets of sliding grab plates 8-1 are simultaneously unfolded to the parking areas 1 on both sides, and after being fixed to the bottom movable parking plates 7 of the parking areas 1 on both sides, the parking areas 1 are lifted as a whole.

[0028] like Figure 7 As shown, the present embodiment provides a process for picking up a car in a shaft-type underground parking garage, comprising the following steps: Step 1: The carrier 8 moves vertically to the floor where the designated vehicle is located; Step 2: Slide the grab plate 8-1 to the bottom of the movable parking plate 7; Step 3: The rotatable telescopic arms 7-1 on the movable parking plate 7 are retracted to both sides of the vehicle parking plate 7-2 and are in a horizontal state, and the rotatable pulley device 7-6 is rotated to the vehicle parking plate 7-2, while the sliding grab plate 8-1 and the movable parking plate 7 are fixed, and the movable parking plate 7 is driven by the sliding grab plate 8-1 to translate onto the carrier 8; Step 4: The remaining movable parking plates on the upper part of the taken out movable parking plate 7 are collectively moved down one layer, and the carrier 8 rises to the ground to take out the vehicle; like Figure 8 As shown, step 4 specifically includes: Step 4-1: After the carrier 8 rises to the ground, the sliding grab plate 8-1 drives the movable parking plate 7 to return to the ground parking area 4, the rotatable telescopic arm 7-1 rotates 90 degrees to keep it horizontal with the movable parking plate 7, and the rotatable pulley device 7-6 rotates to the bottom of the vehicle parking plate 7-2; Step 4.2: After the movable parking plate 7 is fixed at the ground parking area 4, the vehicle leaves, and the sliding grab plate 8-1 is recovered to the carrier 8, and the movable parking plate 7 remains in the same position waiting for parking.

[0029] like Fig. 9 As shown, before picking up the car, the carrier 8 needs to lift the movable parking board 7 of the ground parking area 4 on one side to the top parking board area 3, and then move it down to pick up the car. During this period, the parking area 1 corresponding to the top parking board area 3 cannot store cars, but the other parking area 1 can still store cars. The specific steps are as follows: Step 1: When a vehicle needs to be picked up, the rotatable pulley device of the movable parking board 7 of the ground parking area 4 on one side is rotated to the top of the vehicle parking board 7-2; Step 2: The sliding grab plate 8-1 starts to move to the bottom of the movable parking plate 7 for fixation, and drives the movable parking plate 7 to move onto the carrier 8; Step 3: The carrier 8 is lifted to the height of the top board storage area 3; Step 4: After sliding the grab plate 8-1 to place the movable car storage plate 7 in the top storage plate area 3, the carrier 8 starts to pick up the car.

[0030] Embodiment 2 Based on the underground parking garage described in the first embodiment, this embodiment provides a method for accessing a shaft-type underground parking garage, including the following steps: When parking a vehicle, the vehicle is moved to the movable parking plate 7 at the ground parking area 4, the rotatable telescopic arm 7-1 is rotated to a vertical state, the movable parking plate 7 parks the vehicle to the underground parking area 5 through the shock-absorbing track device 6, and the movable parking plate 7 is fixed to the movable parking plate 7 of other vehicles below through the rotatable telescopic arm 7-1; When taking out the car, first lift the movable parking board 7 of the ground parking area 4 to the top parking board area 3 through the carrier 8, then move the carrier 8 to the corresponding vehicle taking out position, and slide the grab plate 8-1 to the bottom of the movable parking board 7 of the vehicle taking out, and the rotatable telescopic arm 7-1 on the movable parking board 7 is retracted to both sides of the movable parking board 7 and is in a horizontal state, the sliding grab plate 8-1 and the movable parking board 7 are fixed, and the movable parking board 7 is driven by the sliding grab plate 8-1 to move onto the carrier 8, and the remaining other movable parking boards 7 on the upper part of the taken out movable parking board 7 are collectively moved down one layer, and the carrier 8 rises to the ground to take out the vehicle.

[0031] When the sensor alarm device 7-5 or the water level alarm is triggered, the sliding grab plate 8-1 moves to the bottom of the movable parking plate 7 in the alarm area and is fixed. At this time, the carrier 8 moves upward to drive the sliding grab plate 8-1 to lift other movable parking plates 7 and vehicles above the alarm area of ​​the parking area 1.

[0032] When the carrier 8 lifts the movable parking board 7 of the ground parking area 4 to the top parking board area 3, the parking area 1 on the same side of the top parking board area 3 cannot be used for parking, but the parking area 1 on the other side can be used for parking.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features.
