Description

Technical Field

[0001] The invention relates to the field of three-dimensional parking, and in particular to a switching device for three-dimensional parking, a three-dimensional parking garage and a method for storing and retrieving a vehicle. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, the number of cars is also increasing year by year, so parking difficulties have become a social problem that needs to be solved urgently. The limitation of parking space has forced people to develop a three-dimensional parking structure that can make better use of space. A three-dimensional parking garage is a mechanical or mechanical equipment system used to store and retrieve vehicles in maximum quantity. For professional parking lot management companies, a three-dimensional parking garage is an effective means to increase parking lot capacity and increase parking fee income. Three-dimensional parking garages are divided into two types in terms of architectural form: independent and built-in. Independent parking buildings are suitable for underground squares and existing buildings to build parking facilities. Planning and construction should pay attention to the surrounding environment. When conditions permit, integration can be used for external corporate or public service advertising layout to improve economic benefits. Built-in three-dimensional parking garages are suitable for simultaneous planning and construction with new buildings. Parking equipment is attached to the building, which has no impact on regional environmental planning and architectural appearance. The development of the modern parking industry has reached a certain scale, and it has actively expanded the auxiliary functions of parking facilities to provide a variety of services for the community. In the planning and construction of some parking facilities, construction machinery parking facilities are taken as the center, and the surrounding environment, topography, and various needs of the service groups are fully considered to build parking facilities into regional service centers and develop their comprehensive benefits. For example, centralized construction of parking, car washing, car beauty and car repair centers.

[0003] At present, among the many types of stereo garages, the comb-tooth exchange stereo garage is a relatively new stereo parking equipment, which occupies a large market share and becomes the mainstream of stereo garages along with the platform-type lifting and lateral movement stereo garages. However, we noticed that these two types of stereo garages have their own technical advantages, but also have the disadvantages of complex structure, many fault points, high production and maintenance costs, and less than ideal space utilization. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a switching device for three-dimensional parking, a three-dimensional parking garage and a method for storing and retrieving a vehicle.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The present invention provides an exchange device for a three-dimensional parking lot, which includes a pair of exchange mechanisms. Each exchange mechanism includes a cantilever and a main beam. The main beam is pivotally connected to the cantilever. An exchange comb for carrying a vehicle is provided on the cantilever. When the main beam pivots around the cantilever, the exchange comb switches between a horizontal state and a vertical state as the cantilever pivots.

[0007] In a preferred embodiment, for the exchange device for a three-dimensional parking lot, at least one end of the main beam is provided with a pivoting component. The pivoting component includes a connecting arm. One end of the connecting arm is fixed to the main beam, and the other end of the connecting arm is hinged to the cantilever.

[0008] Furthermore, for the exchange device for a three-dimensional parking lot, the pivoting component further includes a pivoting arm. The pivoting arm is installed on the main beam and can pivot together with the main beam.

[0009] In a preferred embodiment, for the exchange device for a three-dimensional parking lot, the pivoting arm is rotatably connected to the main beam. The pivoting component further includes a locking component. The locking component locks the positional relationship between the main beam and the pivoting arm. When the locking component is in the locked state, the main beam pivots together with the pivoting arm. When the locking component is in the unlocked state, the pivoting arm no longer drives the main beam to move.

[0010] Specifically, for the exchange device for a three-dimensional parking lot, the cantilever is suspended by steel wire ropes. The steel wire ropes can be used for suspension at the suspension points at the front and rear ends of the cantilever, and the up-and-down position change of the cantilever is controlled by the steel wire ropes.

[0011] Specifically, for the exchange device for a three-dimensional parking lot, the main beam is suspended by steel wire ropes. The steel wire ropes can be used for suspension at the suspension points provided at the front and rear ends of the main beam, and the pivoting of the main beam around the cantilever is controlled by the steel wire ropes.

[0012] More specifically, for the exchange device for a three-dimensional parking lot and the three-dimensional parking garage, the main beam is connected to the steel wire ropes through the pivoting arm.

[0013] In a preferred embodiment, for the exchange device and the three-dimensional parking garage for three-dimensional parking, the locking component includes a latch and a driver for driving the latch to lock / unlock. A locking hook is provided on the flipping arm, and the locking hook cooperates with the latch. When the locking hook is latched on the latch, the flipping arm is in a locked state. In this state, the flipping arm can drive the main beam to perform a synchronous flipping motion in the same direction; when the latch disengages from the locking hook, the flipping arm is in an unlocked state. In this state, the flipping arm rotates idly around the hinge axis, the torque applied to the main beam disappears, and the main beam no longer flips together with the flipping arm.

[0014] Further, for the exchange device for three-dimensional parking, guiding members are provided at both ends of the cantilever.

[0015] The present invention also provides a three-dimensional parking garage, including a three-dimensional garage rack. A plurality of parking spaces are provided in the three-dimensional garage rack. The three-dimensional parking garage further includes a lifting device, a comb inner frame, and the exchange device as described above. At least one horizontally movable comb inner frame is provided on each floor above the first floor of the three-dimensional garage rack. The lifting device is installed on the three-dimensional garage rack and is used to drive the movement and operation of the exchange device. The exchange device is connected to the lifting device through a steel wire rope and is suspended below the lifting device. The exchange device moves a vehicle into or out of the comb inner frame.

[0016] The present invention also provides a vehicle taking method based on the three-dimensional parking garage as described above, including:

[0017] The lifting device drives the exchange device to operate, so that the exchange comb teeth are in a vertical state (the orientation of the exchange comb teeth flips together with the main beam into a vertical state);

[0018] The lifting device drives the exchange device to move, so that the exchange device reaches a preset working position (this position is set below the comb inner frame of the target floor and is a spatial point that can ensure that the flipping of the main beam of the exchange device at this position is not interfered by anything);

[0019] The lifting device drives the exchange device to operate, so that the exchange comb teeth are in a horizontal state (the lifting device relaxes the control of the main beam, and the unconstrained main beam flips under the action of its own gravity, and the orientation of the exchange comb teeth flips together with the main beam into a horizontal state);

[0020] The lifting device drives the exchange device to move, causing the exchange device to rise and perform a comb tooth exchange with the inner comb tooth frame. The vehicle on the inner comb tooth frame is moved onto the exchange device (during the movement, the exchange comb teeth lift the car from the comb tooth gaps of the inner comb tooth frame, and the car on the inner comb tooth frame is transferred to the exchange device. The exchange device carrying the car stops moving at a position that does not interfere with the lateral movement of the inner comb tooth frame).

[0021] The inner comb tooth frame below the exchange device moves laterally to create a falling channel.

[0022] The lifting device drives the exchange device to move, causing the exchange device to fall, and the vehicle is delivered to the bottom entrance and exit position of the three-dimensional storage rack.

[0023] Further, after the step "The lifting device drives the exchange device to move, causing the exchange device to fall, and the vehicle is delivered to the bottom entrance and exit position of the three-dimensional storage rack", the following is also included:

[0024] The lifting device drives the flipping arm to flip to a vertical state.

[0025] The present invention also provides a vehicle storage method based on the above-mentioned three-dimensional parking garage,

[0026] The vehicle storage method can be the reverse process of the vehicle retrieval method.

[0027] Specifically, the vehicle storage method includes:

[0028] The vehicle drives into and parks on the exchange mechanism at the bottom entrance and exit position of the three-dimensional storage rack (at this time, all four wheels of the car are pressing on the exchange comb teeth of the exchange device);

[0029] The lifting device drives the exchange device to move, causing the exchange device to rise to a preset working position (this position is set above the inner comb tooth frame of the target layer and at a spatial point that does not interfere with the lateral movement of the inner comb tooth frame);

[0030] The inner comb tooth frame to be transferred moves laterally to below the exchange device (the inner comb tooth frame of the target layer in the no-load state moves laterally to directly below the exchange device);

[0031] The lifting device drives the exchange device to move, causing the exchange device to fall and perform a comb tooth exchange with the inner comb tooth frame. The vehicle on the exchange device is moved onto the inner comb tooth frame (during the movement, the exchange comb teeth lower the car into the comb tooth gaps of the inner comb tooth frame, and the car on the exchange device is transferred to the inner comb tooth frame); after the exchange is completed, the exchange device continues to move downward to a position that does not interfere with the flipping of the main beam.

[0032] Further, after the step of "the vehicle drives into and parks on the exchange mechanism at the bottom entrance and exit position of the three-dimensional storage rack" and before the step of "the lifting device drives the exchange device to move, so that the exchange device rises to a preset working position", the following steps are also included:

[0033] The lifting device drives the flipping arm to flip from a vertical state to a horizontal state (the lifting device relaxes the control of the flipping arm, and the flipping arm without restraint flips under the action of its own gravity and flips to a horizontal state towards the side where the inner comb rack is located);

[0034] The locking component locks the flipping arm.

[0035] Further, after the step of "the lifting device drives the exchange device to move, so that the exchange device descends, performs comb exchange with the inner comb rack, and the vehicle on the exchange device is moved onto the inner comb rack", the following steps are also included:

[0036] The lifting device drives the exchange device to operate, so that the exchange comb is in a vertical state;

[0037] The lifting device drives the exchange device to move upward to a standby position;

[0038] The lifting device drives the exchange device to operate, relaxes the tension control of the main beam, the exchange comb loses the tension constraint, and the exchange comb becomes horizontal.

[0039] Compared with the prior art, an exchange device for three-dimensional parking, a three-dimensional parking garage and a method for accessing vehicles provided by the present invention include a pair of exchange mechanisms. The exchange mechanism includes a cantilever and a main beam. The main beam is rotatably connected to the cantilever. An exchange comb for carrying a vehicle is arranged on the cantilever. When the main beam rotates around the cantilever, the exchange comb switches between a horizontal state and a vertical state as the cantilever rotates. For the three-dimensional parking space of the present invention, multiple parking spaces can share one exchange device, which not only has high exchange efficiency, but also has a simple and stable structure, is beneficial to greatly reducing the production cost, is beneficial to reducing the failure rate, and further is beneficial to reducing the maintenance cost, and is beneficial to shortening the construction time of the on-site three-dimensional parking garage, improving the on-site construction efficiency, and saving the labor and material costs. The three-dimensional parking garage of the present invention has multiple advantages, is particularly suitable for popularization and application in this field, and has a very broad market prospect.

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] It should be noted that when a component is referred to as "mounted on", "fixed to" or "disposed on" another component, it can be directly on the other component or there may be an intermediate component at the same time. When a component is referred to as "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0052] It should also be noted that the terms of orientation such as left, right, up, and down in the embodiments of the present invention are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0053] Such as Figures 1-6The present invention provides an exchange device for three-dimensional parking, comprising a pair of exchange mechanisms. The exchange mechanism includes a cantilever 4 and a main beam 2. The main beam 2 is pivotally connected to the cantilever 4. An exchange comb 8 for carrying a vehicle is provided on the cantilever 4. The main beam 2 rotates around the cantilever 4. When the main beam 2 rotates around the cantilever 4, the exchange comb 8 switches between a horizontal state and a vertical state as the cantilever 4 rotates. Preferably, for the exchange device for three-dimensional parking provided by the present invention, one end of the main beam 2 is provided with a flipping component. The flipping component includes a connecting arm 10. One end of the connecting arm 10 is fixed to the main beam 2, and the other end of the connecting arm 10 is hinged to the cantilever 4. The flipping angle of the main beam 2 of the present invention can be limited between 0 and 90°. Specifically, it can be physically limited by the connecting arm 10. The main beam 2 of the present invention is arranged parallel to the cantilever 4, and a preset vehicle width spacing is provided between the two exchange mechanisms so that the exchange comb 8 can just correspond to the positions of the four tires of the vehicle. As for the specific setting of the comb teeth and the principle and method of exchange, they are widely used in the prior art and will not be elaborated in the present invention.

[0054] Furthermore, for the exchange device for three-dimensional parking provided by the present invention, the flipping component further includes a flipping arm 1. The flipping arm 1 is installed on the main beam 2 and can rotate with the main beam 2. Specifically, for the exchange device for three-dimensional parking provided by the present invention, the cantilever 4 is suspended by a steel wire rope, and its up and down position change is controlled by the steel wire rope. Specifically, for the exchange device for three-dimensional parking provided by the present invention, the main beam 2 is suspended by a steel wire rope, and its rotation around the cantilever 4 is controlled by the steel wire rope. More specifically, for the exchange device for three-dimensional parking and the three-dimensional parking garage provided by the present invention, the main beam 2 is connected to the steel wire rope through the flipping arm 1. In order to keep the exchange device stable, the cantilever 4 and the main beam 2 are connected by at least two steel wire ropes, and the present invention arranges them at the ends or positions close to the ends. The steel wire rope of the present invention can be directly arranged on the main beam 2, but preferably, it can be arranged at one end of the flipping arm 1 pointing to the side where the vehicle is located. The flipping arm 1 has a certain length and is installed on the main beam 2. When both it and the exchange comb 8 are in the horizontal state, the end of the flipping arm 1 pointing to the side where the vehicle is located should not be shorter than the end of the exchange comb 8 pointing to the side where the vehicle is located. In this way, the force is more uniform and the movement and operation of the exchange device are more stable.

[0055] Preferably, for the exchange device for stereo parking provided by the present invention, the turnover arm 1 is rotatably connected to the main beam 2. The turnover component further includes a locking component, which locks the positional relationship between the main beam 2 and the turnover arm 1. When the locking component is in the locked state, the main beam 2 turns together with the turnover arm 1; when the locking component is in the unlocked state, the turnover arm 1 no longer drives the main beam 2 to move. Preferably, for the exchange device for stereo parking and the stereo parking garage provided by the present invention, the locking component includes a lock catch 6 and a driver 5 for driving the lock catch 6 to lock / unlock. A lock hook 7 is arranged on the turnover arm 1, and the lock catch 6 cooperates with the lock hook 7. When the lock hook 7 is latched on the lock catch 6, the turnover arm 1 is in the locked state; when the lock catch 6 disengages from the lock hook 7, the turnover arm 1 is in the unlocked state. The driver 5 of the present invention adopts an electric push rod to drive the lock catch 6 to latch or separate from the lock hook 7. The turnover arm 1 of the present invention can rotate independently of the exchange comb teeth 8 (main beam 2), and its rotatable direction is the same as that of the main beam 2. In the unlocked state, the turnover arm 1 turns into a vertical state, without the obstruction of the steel wire rope, so as to facilitate the vehicle to drive out of the exchange device. It should be noted that only one pair of rotatable turnover arms 1 needs to be arranged in the exchange device, and it can be arranged in the two turnover components at the vehicle access end. In this embodiment, a pair of wire rope suspension points symmetric to the turnover arm at the front end of the exchange device are arranged at the rear end of the exchange device. The main beam 2 is matched with the suspension points through a fixed suspension arm (not labeled in the figure). Both the suspension arm and the turnover arm 1 have a certain length, and their (suspension point) end points (and the end point of the exchange comb teeth 7 pointing to the side where the car is located) are basically on the same straight line parallel to the main beam 2, so that the force on the exchange device will be more uniform and the movement will be more stable. For the exchange device for stereo parking provided by the present invention, the turnover arm 1 is only arranged on the exchange mechanism on one side of the vehicle entrance and exit end. This is because when the exchange device reaches the bottom entrance and exit position and the direction of the turnover arm 1 is in the horizontal state, the steel wire rope connected to the turnover arm 1 forms an obstacle to the normal entry and exit of the vehicle and blocks the entrance and exit. The present invention adopts the method of changing the direction of the turnover arm 1 at this entrance and exit, so that it turns from the horizontal state to the vertical state, so that the steel wire rope connected to the turnover arm 1 turns to both sides of the exchange device along with the turnover of the turnover arm 1, removing the traffic obstacle for the vehicle.

[0056] Further, for the exchange device for three-dimensional parking provided by the present invention, guiding members 3 are provided at both ends of the cantilever 4 to facilitate the more stable and smooth movement of the cantilever 4 in the three-dimensional parking garage. The guiding members 3 contribute to the more stable operation of the exchange device in the three-dimensional parking garage. The guiding members 3 only play an auxiliary role in the implementation of the present invention and are not essential. Preferably, the flipping arm 1 of the present invention is hinged to the connecting arm 10, and a spring 9 for resetting is also provided at the hinge. The flipping arm 1 can automatically return to the horizontal state through the spring 9 and its own weight.

[0057] As Figures 7-10 shown, the present invention also provides a three-dimensional parking garage, including a three-dimensional garage rack 101. A plurality of parking spaces are provided in the three-dimensional garage rack 101. The three-dimensional parking garage further includes a lifting device 102, a comb inner frame 104, and the exchange device 103 provided by the present invention as described above. At least one horizontally movable comb inner frame is provided on each floor above the first floor of the three-dimensional garage rack 101. The lifting device is installed on the three-dimensional garage rack 101 and is used to drive the movement and operation of the exchange device 103. The exchange device is connected to the lifting device 102 through a steel wire rope and is suspended below the lifting device 102. The exchange device 103 moves a vehicle onto the comb inner frame 104 or moves a vehicle out of the comb inner frame 104. The lifting device is mainly used to drive the retraction and pulling of the steel wire rope. Those skilled in the art can design it according to the actual situation. The comb inner frame is also a prior art and will not be elaborated here.

[0058] The present invention also provides a vehicle-taking method based on the above three-dimensional parking garage, including:

[0059] S1. The lifting device drives the operation of the exchange device to make the exchange comb in a vertical state. In this embodiment, the orientation of the exchange comb is flipped into a vertical state together with the main beam);

[0060] S2. The lifting device drives the movement of the exchange device to make the exchange device reach a preset working position, which is set at a spatial point below the comb inner frame of the target floor and can ensure that the flipping of the main beam of the exchange device at this position is not interfered with by anything;

[0061] S3. The lifting device drives the operation of the exchange device to make the exchange comb in a horizontal state. Specifically, the lifting device adjusts the force applied to the steel wire rope, relaxes the control of the main beam, and the main beam without the restraint of the steel wire rope tension flips under the action of its own gravity. The orientation of the exchange comb is flipped into a horizontal state together with the main beam;

[0062] S4. The lifting device drives the exchange device to move, causing the exchange device to rise and perform a comb tooth exchange with the inner comb tooth frame. The vehicle on the inner comb tooth frame is moved onto the exchange device. During the movement, the exchange comb teeth lift the car from the comb tooth gaps of the inner comb tooth frame, and the car on the inner comb tooth frame is transferred to the exchange device. The exchange device carrying the car stops moving at a position that does not interfere with the lateral movement of the inner comb tooth frame of the comb tooth type.

[0063] S5. The inner comb tooth frame under the exchange device moves horizontally to leave a falling channel.

[0064] S6. The lifting device drives the exchange device to move, causing the exchange device to fall, and the vehicle is delivered to the bottom entrance and exit position of the three-dimensional storage rack.

[0065] In this embodiment, the vehicle taking method further includes:

[0066] S7. The locking component is unlocked.

[0067] S8. The lifting device drives the flipping arm to flip to a vertical state.

[0068] The present invention also provides a vehicle storing method based on the three-dimensional parking garage as described above.

[0069] The vehicle storing method can be the reverse process of the vehicle taking method.

[0070] Specifically, the vehicle storing method includes:

[0071] A1. The vehicle drives into and parks on the exchange mechanism at the bottom entrance and exit position of the three-dimensional storage rack. At this time, all four wheels of the car are pressed on the exchange comb teeth of the exchange device.

[0072] A2. The lifting device drives the exchange device to move, causing the exchange device to rise to a preset working position, which is set above the inner comb tooth frame of the target layer and at a spatial point that does not interfere with the lateral movement of the inner comb tooth frame.

[0073] A3. The inner comb tooth frame to be transferred horizontally moves to below the exchange device. Specifically, the inner comb tooth frame of the target layer in the no-load state horizontally moves to directly below the exchange device.

[0074] A4. The lifting device drives the exchange device to move, causing the exchange device to fall and perform a comb tooth exchange with the inner comb tooth frame. The vehicle on the exchange device is moved onto the inner comb tooth frame. During the movement, the exchange comb teeth lower the car in the comb tooth gaps of the inner comb tooth frame, and the car on the exchange device is transferred to the inner comb tooth frame. After the exchange is completed, the exchange device continues to move downward to a position that does not interfere with the flipping of the main beam.

[0075] Further, after the step "A1. The vehicle drives into and parks on the exchange mechanism at the bottom entrance and exit position of the three-dimensional storage rack" and before the step "A2. The lifting device drives the exchange device to move so that the exchange device rises to a preset working position", the following steps are also included:

Specifically, the lifting device relaxes the control of the flipping arm, and the flipping arm without restraint flips under the action of its own gravity and flips to a horizontal state toward the side where the inner comb rack is located.

[0077] A1.2. The locking component locks the flipping arm.

[0078] Further, after the step "A4. The lifting device drives the exchange device to move so that the exchange device descends, performs comb exchange with the inner comb rack, and the vehicle on the exchange device is moved onto the inner comb rack", the following steps are also included:

[0079] A5. The lifting device drives the exchange device to operate so that the exchange comb is in a vertical state.

[0080] A6. The lifting device drives the exchange device to move upward to a standby position.

[0081] A7. The lifting device drives the exchange device to operate and relaxes the tension control of the main beam. The exchange comb loses the tension restraint and becomes horizontal.

[0082] In summary, for the three-dimensional parking space of the present invention, multiple parking spaces can share one exchange device, which not only has high exchange efficiency, but also has a simple and stable structure, is beneficial to greatly reducing the production cost, is beneficial to reducing the failure rate, and further is beneficial to reducing the maintenance cost, and is beneficial to shortening the construction time of the on-site three-dimensional parking garage, improving the on-site construction efficiency, and saving the labor and material costs.

[0083] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the appended claims of the present invention.
