Description

Technical Field

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

[0002] The three-dimensional parking garage can automatically place the parked vehicles in the vacant positions. It is a three-dimensional multi-space automatic mechanical garage. The types of three-dimensional parking garages on the market mainly include circulation parking equipment and non-circulation parking equipment.

[0003] Circular parking equipment realizes three-dimensional parking through the circulation of parking spaces. The position of each parking space can be transferred and changed at any time. However, circular parking equipment has disadvantages such as slow car retrieval speed and the need to reserve vacant parking spaces.

[0004] Non-circular parking equipment is equipped with multiple fixed parking spaces in a three-dimensional space. Vehicles are pulled into the fixed parking spaces by external traction. Currently, the most common one is the single-column rotating three-dimensional parking garage.

[0005] A single single-column rotating three-dimensional parking device usually has two fixed parking spaces in the upper and lower directions, and the lower parking space can be used for normal parking of cars. A support rod is set on one side of the two fixed parking spaces, and a lifting and rotating car loading plate is set on the support rod; the car loading plate can be attached to the ground for the car to drive in, and then the car loading plate moves to the upper parking space through lifting and rotation. However, there are great safety hazards in the single-column rotating non-avoidance three-dimensional parking garage. The main reason is that the entire car loading plate will produce a large cantilever effect under the action of its own weight and the overall weight of the car, so that the car loading plate will have a large bending. At the same time, in order to enable the car loading plate to rotate and move up and down, a large motor is required to provide kinetic energy, which will cause a great waste of resources. Moreover, this structure requires the support rod to be able to withstand a large load, which will invisibly increase the mass of the entire support rod. By increasing the thickness of the column to enhance its strength or using composite materials to design, these methods will increase the cost of the entire non-avoidance three-dimensional parking garage during the manufacturing process, which is not conducive to the popularization and use of three-dimensional parking garages.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] Figure 1 The three-dimensional structure diagram of the parking equipment of the embodiment of the present invention is shown. The present invention provides a parking equipment, which includes a load-bearing mechanism 1, a translation mechanism 2, a hoisting mechanism 3 and a transportation platform 4.

[0043] Basically, the load-bearing mechanism 1 includes a load-bearing plate 101 arranged at a preset height, and above the load-bearing plate 10 is a first parking space 111, which can accommodate the transport platform 4 loaded with cars. Optionally, below the load-bearing plate 101 is a second parking space 112 for cars to drive in and park directly.

[0044] The translation mechanism 2 of the embodiment of the present invention includes a translation driving device and a translation connecting member, and the translation connecting member is driven to move based on the translation driving device. For the convenience of description, the area arranged outside the first parking space 111 and close in height to the first parking space 111 is named as the third parking space 113. Generally, the height of the third parking space 113 is the same as or slightly higher than the height of the first parking space 111. The transport platform 4 first moves to the third parking space 113 and then enters the first parking space 111.

[0045] The hoisting mechanism 3 is arranged on the translation connection member, and the hoisting mechanism 3 includes a hoisting drive device and a hoisting connection member; the hoisting connection member is connected to the transport platform 4, and the hoisting connection member drives the transport platform 4 to move up and down based on the hoisting drive device. For the convenience of description, the space area below the third parking space 113 is named as the fourth parking space 114. Generally, when the transport platform 4 is located in the fourth parking space 114, the transport platform 4 is placed on the ground.

[0046] Basically, the parking operation principle of the parking equipment of the embodiment of the present invention is: in the initial state, the transportation platform 4 is located on the fourth parking space 114, and the car can drive into the transportation platform 4 from the outside of the parking equipment and stop on the transportation platform 4; then the lifting mechanism 3 drives the transportation platform 4 to rise and move to the third parking space 113; finally, the transportation platform 4 is driven by the translation mechanism 2 to move to the first parking space 111.

[0047] Correspondingly, the car picking operation principle of the parking equipment of the embodiment of the present invention is: first, the transportation platform 4 is driven by the translation mechanism 2 to move from the first parking space 111 to the third parking space 113, and then the transportation platform 4 is driven by the lifting mechanism 3 to descend from the third parking space 113 to the fourth parking space 114.

[0048] The parking equipment provided in the embodiment of the present invention can be modified for parking lots with any number of parking spaces, and the construction convenience is good; the parking equipment has a simple and reliable structure and runs smoothly, which can ensure the safety of automobile transportation; the transportation platform is evenly stressed, and it is not easy to cause stress concentration or excessive stress that causes falling outside the transportation platform, and it has good transportation reliability.

[0049] Embodiment 2:

[0050] Further, referring to the accompanying drawings Figure 1 The three-dimensional structural diagram of the parking equipment shown in the figure shows that if a car is to enter the transport platform 4, the width of the parking aisle is at least the sum of the lengths of two cars, but in actual implementation, the width of the parking aisle is usually only the sum of the widths of two cars. In order to adapt to the existing parking lot planning, the parking equipment of the embodiment of the present invention optionally further includes a rotating mechanism 5, and the hoisting mechanism 3 is arranged on the translation connection member based on the rotating mechanism 5; the rotating mechanism 5 is arranged on the translation connection member, and the rotating mechanism 5 has a rotating output end, and the hoisting mechanism 3 is arranged on the rotating output end.

[0051] Refer to the attached pictures Figure 2 The three-dimensional structure diagram of the parking equipment of the embodiment of the present invention is shown. By setting the rotating mechanism 5, the lifting mechanism 3 can be driven to rotate by the rotating mechanism 5, thereby driving the transportation platform 4 to rotate. By controlling the rotation of the transportation platform 4, the car entry direction of the transportation platform 4 can be adjusted, so that the car can enter the transportation platform 4 in different directions. Through the parking equipment structure of the embodiment of the present invention, the parking lot aisle width required by the parking equipment can be greatly reduced, and it has good practicality in actual implementation.

The load-bearing mechanism 1 according to the embodiment of the present invention includes a load-bearing plate 101 arranged at a preset height. The load-bearing plate 101 is used to support the transportation platform 4 transported to the first parking space 111. When the transportation platform 4 is stationary in the first parking space 111, the transportation platform 4 is supported by the load-bearing plate 101, which can prevent the hoisting mechanism 3, the rotating mechanism 5 and the translation mechanism 2 from being subjected to stress for a long time, thereby extending the service life of the hoisting mechanism 3, the rotating mechanism 5 and the translation mechanism 2.

[0055] In a specific implementation, optionally, the load-bearing plate 101 can be supported and fixed at a certain height by a series of steel frames. A second parking space 112 can be formed below the load-bearing plate 101, and the second parking space 112 can be used for parking, or the second parking space 112 can be used for obstacle avoidance.

[0056] Embodiment 4:

[0057] The embodiment of the present invention is described with respect to one embodiment of the translation mechanism 2 in the parking equipment described in the first embodiment.

[0058] Figure 3A schematic diagram of the three-dimensional structure of the translation mechanism of an embodiment of the present invention is shown. Figure 4 A side structural schematic diagram of a translation mechanism according to an embodiment of the present invention is shown.

[0059] The translation mechanism of the embodiment of the present invention includes a translation guide rail 201, a translation drive device and a translation connector.

[0060] Specifically, the translation guide rail 201 is an I-shaped guide rail, and a first guide groove 207 and a second guide groove 208 are respectively provided on both radial sides of the translation guide rail 201. Commonly, I-shaped steel can be directly used as the translation guide rail. On the one hand, I-shaped steel has good component strength. On the other hand, I-shaped steel is a standard steel material with low procurement cost, which can reduce the production cost of the parking equipment.

[0061] The translation drive device includes a translation drive element 205 and a translation drive reduction mechanism 206. Optionally, the translation drive element 205 is a drive motor, and the translation drive reduction mechanism 206 is a gear reduction mechanism.

[0063] Specifically, the first roller set 209 is matched in the first guide groove 207 , and the second roller set 210 is matched in the second guide groove 208 .

[0064] The translation drive device drives the first roller group 209 and / or the second roller group 210 to rotate. Specifically, in the embodiment of the present invention, the translation drive element 205 is fixed to the outer side of the second side plate 203, and the output shaft drives the second roller group 210 to rotate through the translation drive reduction mechanism 206. The second roller group 210 is the active wheel group, and the first roller group 209 is the passive wheel group.

[0065] In a specific implementation, the number of the translation driving elements 205 can be set according to the requirements, and accordingly, the number of the driving wheel sets can also be set according to the requirements.

[0066] It should be noted that each roller group includes more than one roller. In a specific implementation, the translation drive device needs to drive at least one of the rollers to rotate, thereby driving the translation connector 210 to move along the translation guide rail.

[0067] In specific implementation, according to actual needs, the translation connection member can also be a linear motion member such as a slider, which is not described in the embodiment of the present invention. In addition, in order to achieve the linear motion of the translation connection member, there are more diverse implementation methods, which are not described in the embodiment of the present invention.

[0068] Embodiment five:

[0069] The embodiment of the present invention is described with respect to one embodiment of the rotating mechanism 2 in the parking equipment described in the second embodiment.

[0070] Figure 5 A schematic diagram of the three-dimensional structure of the rotating mechanism according to an embodiment of the present invention is shown, wherein a portion of the rotating mechanism housing 504 is hidden in order to show the internal structure of the rotating mechanism.

[0071] Basically, the rotating mechanism of the embodiment of the present invention includes the rotating mechanism 5 including a rotating driving device and a rotating connecting member. The driving device drives the rotating connecting member to rotate, and because the hoisting mechanism is arranged on the rotating connecting member, the rotating connecting member can drive the hoisting mechanism to rotate as a whole.

[0072] Specifically, the rotating mechanism 5 of the embodiment of the present invention includes a rotating driving device 501, a rotating pinion 502, a rotating gear 503 and a rotating mechanism housing 504. Optionally, the rotating driving device 501 is a driving motor, the rotating driving device 501 body is fixed on the rotating mechanism housing 504, the rotating shaft of the rotating driving device 501 passes through the rotating mechanism housing 504 and is coaxially connected with the rotating pinion 502; the rotating gear 503 is arranged on the rotating mechanism housing 504 based on the rotating shaft 505. In a specific implementation, the rotating mechanism housing 504 can be fixed on the translation connection member, and the rotating gear 503 is used as the rotating connection member for output; the rotating gear 503 can also be fixed on the translation connection member, and the rotating mechanism housing 502 is used as the rotating connection member for output; in a specific implementation, it is set according to the needs.

[0073] Embodiment six:

[0074] In a specific implementation, in order to ensure the smooth movement of the transport platform 4, the lifting mechanism needs to include a plurality of lifting connectors, and the plurality of lifting connectors have at least three lifting connection ends; the at least three lifting connection ends are respectively connected to the transport platform.

[0075] Optionally, existing parking equipment mostly uses rigid lifting connectors, but rigid lifting connectors take up a large space and are not suitable for use in narrow spaces. Therefore, optionally, the lifting connector of the embodiment of the present invention can use a lifting rope.

[0076] Accordingly, the embodiment of the present invention is described with respect to one embodiment when the lifting connection member adopts a lifting rope.

[0077] Figure 6 The three-dimensional structure diagram of the lifting mechanism according to the embodiment of the present invention is shown. Figure 7 The side view of the lifting mechanism of the embodiment of the present invention is shown. Basically, when the lifting connection member is a lifting rope, the lifting drive device includes a drum and a lifting drive element; the lifting rope is wound on the drum, and the lifting drive element drives the drum to rotate.

[0078] Specifically, the embodiment of the present invention has two drums, namely the first drum 302 and the second drum 303; the number of hoisting ropes is four, namely the first hoisting rope, the second hoisting rope, the third hoisting rope and the fourth hoisting rope. Since the wire rope components are not clearly shown in the structural schematic diagram, they are not shown in the accompanying drawings. Figure 6 Hidden in.

[0079] Specifically, the lifting mechanism of the embodiment of the present invention also includes a drum housing 301, a first drum 302 and a second drum 303 are arranged inside the drum housing 301, and a first lifting rope hole 311, a second lifting rope hole 312, a third lifting rope hole 313 and a fourth lifting rope hole 314 are respectively provided on the drum housing 301.

[0080] Specifically, the first lifting rope and the second lifting rope are wound around the first drum 302 in the same direction, and the first lifting rope and the second lifting rope respectively have a lifting connecting end, and the lifting connecting ends of the first lifting rope and the second lifting rope respectively extend from the first lifting rope hole 311 and the second lifting rope hole 312 to be connected to the transport platform.

[0081] Specifically, the third lifting rope and the fourth lifting rope are wound around the second drum 303 in the same direction, and the third lifting rope and the fourth lifting rope respectively have a lifting connection end, and the lifting connection ends of the third lifting rope and the fourth lifting rope respectively extend from the third lifting rope hole and the fourth lifting rope hole to be connected to the transport platform.

[0082] In the embodiment of the present invention, the first large gear 304 and the second large gear 305 are respectively connected and fixed to the end surface of the same end of the first reel 302 and the second reel 303; the main body of the hoisting drive element 306 is fixed to the reel housing 301, and the output shaft of the hoisting drive element 306 passes through the reel housing 301 and is connected to the driving gear 307. Optionally, the driving gear 307 is driven by the first large gear 304 and the second large gear 305 at the same time through one hoisting drive element 306, and drives the first large gear 304 and the second large gear 305 to rotate at the same time, thereby achieving the purpose of synchronously driving the first reel 302 and the second reel 303 to rotate.

[0083] It should be noted that, since the hoisting connection ends of the first hoisting rope, the second hoisting rope, the third hoisting rope and the fourth hoisting rope are all connected to the transport platform, in order to ensure the smooth lifting and lowering movement of the transport platform and prevent the transport platform from tilting, it is necessary to ensure the synchronization of the movement of the hoisting connection ends of the first hoisting rope, the second hoisting rope, the third hoisting rope and the fourth hoisting rope. If the first drum and the second drum are driven by two hoisting drive elements 306, due to the differences in the hoisting drive elements 306, it is easy for the hoisting connection ends of the first hoisting rope, the second hoisting rope, the third hoisting rope and the fourth hoisting rope to move asynchronously, causing the transport platform to tilt and causing an accident in which the car accidentally falls. The lifting mechanism of the embodiment of the present invention, under the condition that the transport platform is connected to at least three lifting connection ends, synchronously drives the two drums to move through a lifting drive element 306, and each drum is provided with two lifting ropes, which can well achieve the purpose of smooth lifting and lowering of the transport platform and has good practicality. In addition, it should be noted that in order to ensure that the movement directions of different lifting connection ends are the same, the winding directions of the lifting ropes on the two drums should be opposite.

[0084] Embodiment seven:

[0085] When the lifting connection member adopts a lifting rope, in order to avoid the lifting rope from contacting the car and scratching the car, the connection position between the lifting connection end and the transportation platform can be optionally set at a certain height. Specifically, the present invention is described with respect to one of the transportation platform structures.

[0086] Combined with the attached pictures Figure 1 The three-dimensional structure diagram of the parking equipment of the embodiment of the present invention is shown.

The roots of the transport columns 402 are fixed to the transport base plate 401 and connected to the transport columns 402 and the hoisting connection ends. Through this embodiment, the connection position of the hoisting connection end and the transport platform can be raised to a certain height. When the hoisting rope is tightened, the hoisting rope will not scratch the car due to the change in posture, which has good practicality.

[0087] Accordingly, an embodiment of the present invention further provides a three-dimensional parking garage, wherein the three-dimensional parking garage comprises a plurality of parking devices as described above. Optionally, the plurality of parking devices may be arranged side by side.
