Description

Technical Field

[0001] The present invention relates to the technical field of mechanical three-dimensional parking, and in particular to a safe self-locking multi-layer flat mobile parking system and a parking method. Background Art

[0002] Among the nine categories of mechanical parking equipment in my country, flat-surface mobile parking equipment has a very high cost-effectiveness. It can be divided into single-layer flat-surface mobile and multi-layer flat-surface mobile, and can be built on the ground, semi-above ground, or completely underground. The combination is very flexible, but its market share has been hovering between fourth and fifth in recent years. There are two main reasons: First, the flat-surface mobile lifting equipment on the market generally uses chains or wire ropes for lifting, and a positioning mechanism (pin) needs to be added when leveling to meet the leveling accuracy. Therefore, its cost is relatively high and its operating efficiency is low, and it does not reflect the characteristics of mechanical parking equipment such as speed, safety, and high reliability.

[0003] Second, the market generally adopts the elevator + transverse vehicle + transporter mode, that is, the transverse vehicle and the elevator are interlocked. When the transverse vehicle needs to move horizontally, the elevator must be fixed on the flat track position of the transverse vehicle to prevent the transverse vehicle from falling from the end of the track during operation and causing safety accidents. However, this mode greatly reduces the utilization efficiency of flat mobile parking equipment, especially elevators.

[0004] Therefore, there is an urgent need for a parking system to solve the safety and efficiency problems existing in the operation of the current horizontal mobile mechanical parking equipment transverse vehicle. Summary of the Invention

[0005] In response to the above problems, the inventors have provided a safe, self-locking, multi-layer flat mobile parking system and warehousing method, which changes the inherent working mode in which the elevator must be fixed on the flat track on which the transverse vehicle runs and can only move after the transverse vehicle returns. At the same time, it reduces the risk of the transverse vehicle slipping off the running track, ensuring safety while improving parking efficiency.

[0006] According to a first aspect, the present invention provides a safe, self-locking, multi-layer flat mobile parking system, comprising: a control system, a parking rack, a lift, a lifting platform, a transverse vehicle, and a transporter, wherein the control system is connected to the lift, the lifting platform, the transverse vehicle, and the transporter, the lifting platform is provided with a position detection device and a running track for the transverse vehicle to move, the position detection device is connected to the control system, and is used to detect whether the transverse vehicle is on the lifting platform, each layer of the parking rack is provided with a lane track, and when parking or retrieving a vehicle, the transverse vehicle moves along the running track to the lane track, the transverse vehicle is provided with an appearance detection device, and the appearance detection device is connected to the control system, and is used to detect whether the vehicle has completely entered the transverse vehicle; and further comprising:

[0007] The first baffle is provided on the side of the lifting platform close to the parking frame and is used to limit the sliding of the transverse vehicle on the lifting platform along the running track;

[0008] A second baffle is provided on one side of the end of the lane track of the parking rack, and is used to prevent the transverse vehicle located on the lane track from sliding out of the lane track;

[0009] The first baffle and the second baffle are both configured to rotate around the axis of their mounting pins. In a free state, the first baffle and the second baffle are in a blocking state. When the lifting platform reaches the tunnel track position, the first baffle and the second baffle rotate to release the blocking of the transverse vehicle located on the lifting platform and / or the tunnel track.

[0010] Furthermore, the safe self-locking multi-layer flat mobile parking system also includes:

[0011] A first shift fork is provided on a side of the lifting platform close to the parking frame and located at a plane lower than the base of the transverse vehicle, and is used to shift the second baffle;

[0012] A second shift fork is provided on a side of the lifting platform close to the parking frame, and is used to shift the first baffle;

[0013] When the lifting platform reaches the tunnel track position, the first fork shifts the second baffle to rotate, and the second fork shifts the first baffle to rotate to release the blocking of the first baffle and the second baffle to the transverse vehicle. When the first fork is separated from the second baffle and the second fork is separated from the first baffle, the first baffle and the second baffle return to the blocking state.

[0014] Furthermore, the first baffle and the second baffle are configured in a “┴” shape.

[0015] Furthermore, the safety self-locking multi-story flat mobile parking system further includes: a distance detection device, which is provided on the elevator base and is used to detect the distance between the elevator base and the lifting platform.

[0016] According to the second aspect, the present invention further provides a warehousing method, comprising:

[0017] The control system controls the transporter to move to the location of the vehicle to be parked, and moves the vehicle to be parked onto the transverse transport vehicle;

[0018] After the control system confirms that the vehicle has completely entered the transverse vehicle through the shape detection device, it drives the lifting platform to move to the designated level;

[0019] After the lifting platform moves to the designated floor, the first and second baffles rotate to release the obstruction of the transverse vehicle on the lifting platform, and the control system drives the transverse vehicle to move to the designated position in the laneway track; after the position detection device detects that the transverse vehicle has completely left the lifting platform, the control system drives the lifting platform to perform the next task;

[0020] After the traverse vehicle reaches the designated position in the laneway track, the transporter parks the vehicle in the designated parking space and then returns to the traverse vehicle, which stays on the laneway track;

[0021] The control system drives the lifting platform that has completed its task to move to the level where the transverse vehicle that has completed storage is located. The first baffle and the second baffle rotate to remove the obstruction to the transverse vehicle on the aisle track. The control system drives the transverse vehicle back to the lifting platform. After the position detection device detects that the transverse vehicle has completely entered the lifting platform, the control system drives the lifting platform to perform the next task.

[0022] Working principle of the present invention:

[0023] Taking the rising of the lifting platform as an example, when the lifting platform rises to the tunnel track position, the first fork drives the second baffle to rotate, and the second fork drives the first baffle to rotate, so that the first baffle and the second baffle are released from the original blocking state, and then the transverse vehicle moves along the running track to the tunnel track, and then the lifting platform can leave the tunnel track of this layer and go to other layers. After the lifting platform leaves, the first baffle and the second baffle are automatically reset under the action of gravity, and the second baffle will block the transverse vehicle of the tunnel track to prevent it from sliding out from the end.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The safe self-locking multi-level flat mobile parking system provided by the present invention ensures the translation safety of the transverse vehicle during track operation or the lifting safety of the transverse vehicle on the lifting platform of the elevator by setting the first baffle and the second baffle.

[0026] (2) The setting of the first baffle and the second baffle provides a basis for the independent operation of the transverse vehicle and the lifting platform for accessing vehicles between different layers in the three-dimensional space, so as to change the operation mode in which the elevator must be fixed on the plane track position of the transverse vehicle, and improve the low efficiency of the original multi-layer plane mobile mechanical three-dimensional parking garage.

[0027] (3) The blocking of the transverse vehicle adopts a purely mechanical design, which is more reliable and can reduce the construction cost of the stereo garage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below through specific embodiments with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figure 1As shown, the present invention provides a safe self-locking multi-story flat mobile parking system, including: a control system, a fixed platform 5, a rotating platform 6, a parking rack 1, an elevator 2, a lifting platform 21, a transverse vehicle 3 and a carrier 4. The control system is connected to the elevator 2, the transverse vehicle 3 and the carrier 4 to control their operation. In this embodiment, two elevators 2 are equipped, which are respectively located at the two ends of the parking rack 1. The elevator 2 is arranged between the fixed platform 5 and the rotating platform 6. The fixed platform 5 and the rotating platform 6 can be replaced as needed, such as using a double fixed platform, etc., which will not be described in detail here. The lifting platform 21 is arranged on the elevator 2 and is driven to rise and fall by the elevator 2. A running track 22 for the transverse vehicle 3 to move is provided on it. A distance detection device 8 is provided on the base of the elevator 2. The distance detection device 8 is preferably arranged directly below the running track 22 to detect the height of the running track 22. Two parking racks 1 are provided, one on each side of the elevator 2. Each rack has several levels, each with multiple parking spaces. Roadway tracks 11 are installed on each level of the rack 1, near the elevator 2. A position detection device 9 is installed on the lifting platform 21. This device is connected to the control system and is used to detect whether the traversing vehicle 3 is on the lifting platform 21. The traversing vehicle 3 is also equipped with an appearance detection device 31, which is connected to the control system and is used to detect whether the vehicle has fully entered the traversing vehicle 3.

[0043] like Figure 2 As shown, when storing or retrieving a vehicle, the elevator 2 drives the transverse vehicle 3 and the carrier 4 on the transverse vehicle 3 to move to the corresponding layer. At the same time, the distance detection device 8 detects the height of the running track 22 in real time. When the running track 22 is at the same height as the aisle track 11, it stops. At this time, the transverse vehicle 3 moves along the running track 22 to the corresponding parking space position on the aisle track 11, and then the carrier 4 enters the parking space to store or retrieve the vehicle.

[0044] In this embodiment, the distance detection device 8 is used for detection, and the motion control real-time positioning is used to replace the existing mechanical positioning mechanism, which has a simpler structure, lower cost, and higher leveling efficiency.

[0045] Furthermore, if Figure 5-10As shown, two first baffles 72 and two first shift forks 71 are provided on the side of the lifting platform 21 near the parking rack 1. Second baffles 74 and second shift forks 73 are provided at both ends of the roadway track 11. The first shift fork 71 corresponds to the second baffle 74, and the second shift fork 73 corresponds to the first baffle 72. The first baffle 72 and the second baffle 74 are both in a "┴" shape and can rotate around the axis of their mounting pins. In the free state, the first baffle 72 and the second baffle 74 exhibit a relatively straight "┴" shape under the action of gravity. The first baffle 72 and the second baffle 74 are both in a blocking state. The first baffle 72 is used to prevent the traversing vehicle 3 from slipping and falling along the running track 22 during vertical lifting operation. The second baffle 74 is used to prevent the traversing vehicle 3 from sliding off the roadway track 11 when the roadway track 11 is moving.

[0046] Taking the entry of a vehicle into the warehouse as an example, after the transporter 4 moves the vehicle from the platform to the transverse vehicle 3, the control system confirms through the shape detection device 31 that the vehicle has completely entered the transverse vehicle 3, and then the control system drives the elevator 2, driving the lifting platform 21 and the transverse vehicle 3 to rise. The distance detection device 8 detects the height of the running track 22 in real time. When the running track 22 reaches the corresponding height of the roadway track 11 on the designated layer, the elevator 2 stops. At this time, When the first fork 71 is in the rising state, the first fork 71 will move the arc portion of the lower end of the second baffle 74 to make it rotate, thereby tilting the vertical portion of the second baffle 74, and the second baffle 74 will rotate to a position lower than the transverse vehicle 3 and be maintained under the support of the first fork 71; at the same time, the second fork 73 will also move the horizontal portion of the upper end of the first baffle 72 to make the first baffle 72 rotate to a position lower than the transverse vehicle 3 and be maintained under the action of the second fork 73, and the first baffle 72 and the second baffle 72 exit the blocking state, and then the transverse vehicle 3 enters the lane track 11 along the running track 22. After the position detection device 9 detects that the transverse vehicle 3 has completely driven out of the lifting platform 21, the control system drives the lifting platform 21 to move to the platform to perform the next warehousing task or move to other floors to receive the transverse vehicle 3 that is stationary on the lane track 11 of other floors or move to other lane tracks 11 to receive the transverse vehicle 3 carrying the vehicle when leaving the warehouse. When the lifting platform 21 leaves this layer, the first fork 71 separates from the second baffle 74, and the second fork 73 separates from the first baffle 72. Under the action of gravity, the first baffle 72 and the second baffle 74 return to the blocking state, that is, the vertical parts of the first baffle 72 and the second baffle 74 return to a position higher than the base of the transverse vehicle 3, thereby blocking the transverse movement 3 on the tunnel track 11.

[0047] After the transverse vehicle 3 moves to the corresponding parking space, the transporter 4 drives the vehicle into the parking space, and then the transporter 4 returns to the transverse vehicle 3. The transverse vehicle 3 stays on the aisle track 11 until the control system moves the lifting platform 21 to that layer, and then the transverse vehicle 3 moves into the lifting platform 21. After the position detection device 9 detects that the transverse vehicle 3 has completely entered the lifting platform 21, the control system drives the lifting platform 21 to return to the platform to perform the next warehousing task or move to other aisle tracks 1 to perform the outbound task.

[0048] In summary, the setting of the first baffle 72 and the second baffle 74 can block the transverse vehicle 3 during the vertical lifting process and along the lane track 11, providing a basis for freeing the elevator 2 and the lifting platform 21, making it possible for the elevator 2 and the lifting platform 21 to quickly engage in the next access task. That is, taking storage as an example, when the lifting platform 21 moves to the corresponding layer, the position detection device 9 detects the transverse vehicle 3 in real time. When it is detected that the transverse vehicle 3 has completely entered the lane track 11, the elevator 2 can drive the lifting platform 21 to other layers to meet the transverse vehicle 3 on other layers or return to the platform to meet the new transverse vehicle 3, thus realizing a parking method in which the plane-moving transverse vehicle 3 and the vertically lifting elevator 2 can realize independent operation between different layers in a three-dimensional space to access vehicles, while ensuring safety, greatly improving parking efficiency.

[0049] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications, or substitutions based on the concept of the present invention.
