Description

Technical Field

[0001] The present invention relates to the technical field of mechanical stereo garages, and in particular to a parking device, a parking system and a method for a four-way transversely movable vehicle loading plate. Background Art

[0002] At present, the parking problem in old residential areas in the city center has been difficult to solve. Old residential areas were built earlier, with high population density and few planned parking spaces. With the popularization of private cars, the problem of residents' parking difficulties has become more and more obvious. Among the various types of mechanical three-dimensional parking garages, horizontal circulation parking garages can freely move cars horizontally within the garage plane. They have the characteristics of small footprint, high car density and short construction time, which are very suitable for old residential areas with high-density parking.

[0003] However, existing horizontal circulation parking garages have complex mechanical structures, high construction costs, and are difficult to popularize. For example, the patent announcement number is CN109642433B, and the name is parking rack, parking device and lifting rack, which specifically discloses that "it is used to store parking pallets for placing vehicles and transport parking pallets in the transverse direction and the longitudinal direction. The parking rack has: conveying wheels arranged at the four corners of the rectangle of the shelf frame, and the rectangle has two sides parallel to the transverse direction and two sides parallel to the longitudinal direction of the shelf frame; a conveying drive for rotating a pair of conveying wheels located on the diagonal of the rectangle; a pair of first connecting rods and a pair of second connecting rods for connecting the four conveying wheels into a rectangle; and a wheel steering mechanism for synchronously orienting the conveying wheels." In the above-mentioned prior art, the guide rail steering mechanism of the horizontal circulating parking pallet (i.e., the vehicle loading plate) is integrated at the bottom of the vehicle loading plate, resulting in a complex structure of the vehicle loading plate and a high manufacturing cost; at the same time, the main load-bearing beam node inside the vehicle loading plate needs to be cut off to set the steering shaft system, and the main load-bearing beam node inside the vehicle loading plate needs to be cut off to set the steering guide rail. Under the same main load-bearing beam design height, the overall strength of the vehicle loading plate itself is greatly reduced, and it is difficult to carry heavier vehicles. This limits the overall cost and performance indicators of the horizontal circulation garage, and has a significant impact on its marketability.

[0004] In addition, when the vehicle loading plate is moved horizontally to the position of the vehicle loading frame, the movement positioning must be precise. Only when the supporting wheel groups are aligned with the guide rail steering mechanism at the bottom of the vehicle loading plate can they rotate at the same time to drive the steering. If there is a certain position error between the vehicle loading plate and the parking frame, the supporting wheel groups are prone to get stuck when rotating, resulting in the equipment being unable to turn smoothly. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to solve the problem of decreased load-bearing capacity of the vehicle loading plate and positioning error in lateral movement of the vehicle loading plate.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A parking device for a four-way transversely movable vehicle loading plate comprises a vehicle loading frame and a vehicle loading plate located above the vehicle loading frame and capable of being transversely movable in four directions therefrom, wherein the vehicle loading frame is provided with transversely and longitudinally arranged side guide rail assemblies, and guide wheel clamping grooves are provided on the side guide rail assemblies;

[0008] The bottom of the vehicle loading plate is provided with side guide wheels;

[0009] A steering drive assembly is provided in the vehicle carrier frame, and a plurality of side guide rail steering assemblies corresponding to the positions of the guide wheel slots are provided on the steering drive assembly. The steering drive assembly drives the plurality of side guide rail steering assemblies to rotate synchronously, and alternately overlaps with the guide wheel slots on the transverse and longitudinal side guide rail assemblies, and when rotating, the positioning deviation between the side guide rail steering assembly and the side guide wheel can be forcibly corrected.

[0010] As a further solution of the present invention: the steering drive assembly includes a basic frame, a driving member, and a side guide rail steering assembly installed at the four corners of the basic frame through a movable connecting rod, and two groups of driven roller assemblies and two groups of traveling roller assemblies are also installed at the four corner positions of the basic frame. The driving member can drive the two groups of driven roller assemblies, the two groups of traveling roller assemblies and the four side guide rail steering assemblies to rotate simultaneously.

[0011] As a further solution of the present invention: the driving member includes a chain transmission assembly and a steering motor group, the chain transmission assembly includes a rotating driving sprocket respectively connected to the driven roller assembly and the traveling roller assembly, and the steering motor group can drive the rotating driving sprocket to rotate through the chain.

[0012] As a further solution of the present invention: angle sprockets are provided on both sides of each of the rotary drive sprockets, wherein the angle sprockets are meshedly connected with the chain from the outside.

[0013] As a further solution of the present invention: the travel wheel assembly includes a rotating shaft 2 connected to the corresponding rotating drive sprocket, the upper part of the rotating shaft 2 is connected to a support wheel 2 that can contact the carrier frame, and one side of the support wheel 2 is provided with a travel motor that can drive it to rotate.

[0014] As a further solution of the present invention: the driven roller assembly includes a rotating shaft connected to a corresponding rotating driving sprocket, and the upper part of the rotating shaft is connected to a roller capable of contacting the vehicle carrier.

[0015] As a further solution of the present invention: each of the rotating drive sprockets is connected to the side guide steering assembly through a movable connecting rod.

[0016] As a further solution of the present invention: the positioning deviation is ≦30 mm.

[0017] The present invention also discloses a parking system, including a vehicle lifting frame and a plurality of parking mechanisms on different levels, wherein the vehicle lifting frame can move a vehicle to a parking mechanism on a designated level, and a group of vehicle carriers and vehicle carrier plates are also arranged on the vehicle lifting frame;

[0018] The parking mechanism on each layer includes the above-mentioned vehicle loading frame and the vehicle loading plate. The vehicle loading frames on each layer are arranged in a rectangular array in several groups. The number of the vehicle loading plates is one group less than the number of the vehicle loading frames. The vehicle loading plates can be moved horizontally or vertically to the designated vehicle loading frames.

[0019] The present invention also discloses a parking method of a parking device, comprising the following steps:

[0020] In the initial state, the vehicle moves onto the vehicle loading plate, which is located at the center of the vehicle loading frame, and all the wheel assemblies and the side guide rail steering assemblies in the vehicle loading frame are located in a transverse position, and the side guide wheels of the vehicle loading plate are accommodated in a transverse guide channel formed by the side guide rail steering assemblies and the side guide rail assemblies; the steering drive assembly of the vehicle loading frame is started, pushing the vehicle loading plate to move transversely and drive to another adjacent vehicle loading frame;

[0021] When the vehicle carrier plate moves horizontally to the center position of the adjacent vehicle carrier frame and stops, the steering drive assembly of the adjacent vehicle carrier frame starts the rotation action, switches all the supporting wheel assemblies and the side guide rail steering assembly of the vehicle carrier frame to the longitudinal position state, and forcibly corrects the possible positioning deviation of the side guide wheels here, and the side guide wheels of the vehicle carrier plate are accommodated in the longitudinal guide channel formed by the side guide rail steering assembly and the side guide rail assembly; the steering drive assembly of the vehicle carrier frame starts, pushing the vehicle carrier plate to move longitudinally towards another adjacent vehicle carrier until it moves to the designated vehicle carrier frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention arranges a steering drive assembly with switchable directions and a side guide steering assembly and other structures on the vehicle carrier frame. The steering drive assembly can drive the vehicle carrier plate to move horizontally or vertically above the vehicle carrier frame, and simultaneously switch the side guide wheel direction and the side guide direction of the vehicle carrier plate. Only a single drive motor is required to realize the above actions, and the various actions are mechanically synchronized, with consistent rotation angles and reliable rigidity.

[0024] 2. When the vehicle carrier plate of the present invention is moved and positioned to the center of the steering drive assembly, when the movement direction of the vehicle carrier plate is switched, the side guide surface of the side guide rail steering assembly rotates tangentially around the side guide wheel of the vehicle carrier plate; if there is a large positioning error between the vehicle carrier plate and the vehicle carrier frame, the side guide surface of the side guide rail steering assembly squeezes the side guide wheel around the rotation center to forcibly correct its position until the vehicle carrier plate coincides with the center of the steering drive assembly and the angles are consistent; the obvious beneficial effect is that each time the vehicle carrier plate turns, the steering mechanism can forcibly correct the position of the vehicle carrier plate and eliminate the original positioning error, and mechanical hard synchronization is added to the traditional sensor positioning for correction, thereby achieving accuracy in the movement of the vehicle carrier plate; the control requirements for the positioning accuracy of the vehicle carrier plate become lower; when installing an array of multiple parking devices, the requirements for the straightness and parallelism of multiple series guide rails are greatly reduced, which is conducive to rapid construction.

[0025] 3. The core component of the parking device of the present invention is the steering drive assembly, which integrates multiple action mechanisms such as vehicle plate bearing, lateral or longitudinal drive, lateral or longitudinal drive direction switching, lateral or longitudinal side guide direction switching, etc. The beneficial effect brought by this is that the equipment has a high degree of modularity, which is convenient for rapid array installation to form a large flat garage; and the core functions are concentrated, and the assembly can be completed in the factory, which is convenient for installation and debugging on the subsequent project site, and has great promotion value.

[0026] 4. During the switching process of the lateral direction of the vehicle loading plate of the present invention, the vehicle loading plate can carry loads without any lifting action, so that the parking device can accommodate a heavier car and the energy consumption during the transportation process is lower; only side guide wheels need to be set on the bottom surface of the vehicle loading plate without other complex mechanisms; the vehicle loading plate has a simple structure, strong load-bearing capacity, is easy to manufacture and has a very low cost.

[0027] 5. The steering drive assembly and the side guide steering assembly of the present invention are both arranged on the vehicle carrier frame, and no power device for steering and driving is arranged on the vehicle carrier plate to prevent affecting the load-bearing weight of the vehicle carrier plate; the present invention has high overall performance, greatly reduces the cost compared with traditional technologies, and has high market promotion value.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are 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.

[0055] Example 1

[0056] Reference Figure 1 and Figure 3 A parking device for a four-way transversely movable vehicle loading plate comprises a vehicle loading frame 1 and a vehicle loading plate 2 which is installed above the vehicle loading frame 1 and can be transversely movable in four directions of the vehicle loading frame 1, front, back, left, and right, and a car is loaded on the vehicle loading plate 2.

[0057] For ease of understanding and description, Figure 1 The head of the vehicle is the front end, the rear end is the rear end, and the other directions are based on this and analogy. It should be understood that this orientation setting is only for the convenience of description and understanding, and cannot be understood as a limitation of the present invention.

[0058] Reference Figure 2The vehicle-carrying plate 2 is arranged on the upper part of the vehicle-carrying frame 1 and is supported by the supporting wheel assembly inside the vehicle-carrying frame 1. It can be driven by the traveling supporting wheel assembly to realize lateral and longitudinal translation. Four sets of fixed side guide wheels 21 are arranged on the back side of the vehicle-carrying plate, which cooperate with the side guide surfaces of the side guide rail steering assembly 121 in the vehicle-carrying frame 1 to realize traveling guidance.

[0059] Reference Figure 3 The vehicle carrier 1 includes a bottom supporting steel structure 11, and a steering drive assembly 12, a transition wheel assembly 13 and a side guide rail assembly 14 installed on the supporting steel structure 11; wherein the supporting steel structure 11 is arranged on the ground of the garage parking area, the bottom is connected to the ground, and the upper part is constructed to form a three-dimensional space for parking vehicles; the steering drive assembly 12 is nested inside the supporting steel structure 11 and connected to the supporting steel structure 11.

[0060] Furthermore, the transition wheel assemblies 13 are arranged at the edges of the four sides of the upper surface of the supporting steel structure, and two groups are symmetrically arranged on each side. When the vehicle loading plate 2 drives away from the edge of the supporting steel structure 11, the vehicle loading plate 2 is temporarily supported by the corresponding transition wheel assemblies 13.

[0061] Further, the side guide rail assembly 14 includes two transverse guide rails 142 and two longitudinal guide rails 141, and the inner side edges of the two transverse guide rails 142 and the two longitudinal guide rails 141 are provided with side guide surfaces, which are arranged on the upper part of the supporting steel structure 11; the steering drive assembly 12 is located in the intermediate driving area formed by the two transverse guide rails 142 and the two longitudinal guide rails 141; the two transverse guide rails 142 and the two longitudinal guide rails 141 extend to the edge of the supporting steel structure 11 in the transverse and longitudinal directions. Among them, as the steering drive assembly 12 drives the rotation of the side guide rail steering assembly 121, the side guide surfaces of the side guide rail steering assembly 121 and the transverse guide rails 142 and the longitudinal guide rails 141 can overlap alternately in the transverse or longitudinal directions; it should be noted that the two sets of transition wheel assemblies 13 located on the longitudinal side of the supporting steel structure 11 are located between the two longitudinal guide rails 141; similarly, the two sets of transition wheel assemblies 13 located on the transverse side of the supporting steel structure 11 are located between the two transverse guide rails 142.

[0062] Further, refer to Fig.11 Two groups of transverse guide rail slots 1421 are symmetrically provided on the two transverse guide rails 142, and two longitudinal guide rail slots 1411 are symmetrically provided on the two longitudinal guide rails 141. The transverse guide rail slots 1421 and the longitudinal guide rail slots 1411 form a cross-shaped design. The transverse guide rail slots 1421 and the longitudinal guide rail slots 1411 have the same size and are used to carry the side guide rail steering assembly 121.

[0063] When the side guide steering assembly 121 rotates to the lateral position, the four side guide steering assemblies 121 coincide with the two lateral guide slots 1421 on the two lateral guide rails 142, so that the two lateral guide rails 142 form a relatively complete lateral guide rail for the lateral movement of the side guide wheel 21 below the vehicle loading plate 2;

[0064] When the side guide steering assembly 121 rotates to the longitudinal position, the four side guide steering assemblies 121 coincide with the two longitudinal guide slots 1411 on the two longitudinal guide rails 141, so that the two longitudinal guide rails 141 form a relatively complete transverse guide rail for the longitudinal movement of the side guide wheels 21 below the vehicle loading plate 2.

[0065] Reference Figure 4 and Figure 5 The steering drive assembly 12 includes a base frame 124, and a side guide steering assembly 121, a chain transmission assembly 122, a steering motor assembly 123, a travel roller assembly 125 and a driven roller assembly 126 arranged above the base frame 124. There are two sets of the travel roller assembly 125 and the driven roller assembly 126, which are arranged in a rectangular shape and cross-arranged at the upper four corners of the base frame 124 and can rotate around their vertical axes; that is, the two sets of the travel roller assembly 125 are arranged diagonally, and the two sets of the driven roller assembly 126 are also arranged diagonally.

[0066] Furthermore, the steering motor group 123 is arranged in the middle of the basic frame 124, and all the traveling roller assemblies 125 and the driven roller assemblies 126 are connected in series through the chain transmission assembly 122, and all the traveling roller assemblies 125 and the driven roller assemblies 126 are driven by the steering motor group 123 and the chain transmission assembly 122 to rotate along their rotation axes.

[0067] Reference Figure 3 and Figure 4 The basic frame 124 is designed as a rectangular frame, and its two ends are fixed on the middle support rod of the supporting steel structure 11; and the transverse guide rail and the longitudinal guide rail are located above the basic frame 124, and the basic frame will not affect the lateral movement of the vehicle loading plate 2.

[0068] Reference Figure 6 , Figure 7 , Figure 8 and Fig. 9 The chain transmission assembly 122 includes a chain 1221, a rotating drive sprocket 1222, an angle sprocket 1223, and a tensioning rod 1224. The rotating drive sprocket 1222 is provided with four groups, which are respectively connected to two groups of driven roller assemblies 126 and two groups of walking roller assemblies 125. The steering motor group 123 can drive the rotating drive sprocket 1222 to rotate through the chain 1221.

[0069] Furthermore, each rotating driving sprocket 1222 is provided with an angle sprocket 1223 on both sides, wherein the angle sprocket 1223 is meshed and connected with the chain 1221 from the outside; each rotating driving sprocket 1222 is connected to the side guide steering assembly 121 through a movable connecting rod;

[0070] Further, the travel wheel assembly 125 includes a second rotating shaft 1253 connected to the corresponding rotating driving sprocket 1222, the upper part of the second rotating shaft 1253 is connected to a second wheel 1252 capable of contacting the vehicle carrier 1, the second wheel 1252 can rotate freely around a horizontal axis, and a travel motor 1254 capable of driving the second wheel 1252 to rotate is provided on one side thereof;

[0071] Furthermore, the driven roller assembly 126 includes a rotating shaft 1263 connected to the corresponding rotating driving sprocket 1222, and the upper part of the rotating shaft 1263 is connected to a roller 1262 capable of contacting the vehicle carrier 1, and the roller 1262 can rotate freely around a horizontal axis.

[0072] Reference Figure 6 , Fig.13 and Fig.14 The top side of the side guide rail steering assembly 121 is provided with a side guide surface, which is arranged on the outside of each roller assembly on the basic frame 124. The side guide rail steering assembly 121 is connected to the bottom rotation driving sprocket 1222 of the driven roller assembly 126 through the movable connecting rod 1261, that is, when the driven roller assembly 126 rotates, it can drive the corresponding side guide rail steering assembly 121 to rotate; the side guide rail steering assembly 121 is connected to the bottom rotation driving sprocket 1222 of the traveling roller assembly through the movable connecting rod 2 1251, that is, when the traveling roller assembly rotates, it can drive the corresponding side guide rail steering assembly 121 to rotate, and both can rotate around the vertical axis;

[0073] It should be noted that the steering motor assembly 123 drives the driven roller assembly 126 and the traveling roller assembly 125 to rotate around their vertical axes through the chain transmission assembly, so that all the roller assemblies can rotate synchronously within the range of 0 to 90 degrees, that is, the roller assemblies have lateral (such as Fig.14 as shown) and longitudinally (as Fig.13 Two angular direction states as shown).

[0074] When the driven roller assembly 126 and the traveling roller assembly 125 rotate, the movable link 1 1261 and the movable link 2 1251 synchronously drive the corresponding side guide rail steering assembly 121 to rotate within the range of 0 to 90 degrees, so that the side guide rail steering assembly 121 rotates in the lateral direction (such as Fig.14 as shown) and longitudinally (as Fig.13 The switching of two angular directions (as shown), and the directions of the driven roller assembly 126 and the traveling roller assembly 125 are always parallel to the direction of the side guide rail steering assembly 121.

[0075] When the vehicle carrier plate 2 moves to the center of the steering drive assembly 12, the center of the vehicle carrier plate side guide wheel 21 coincides with the rotation center of the side guide rail steering assembly 121, and a positioning sensor can be set here for positioning monitoring when the vehicle carrier plate 2 enters. When the driven roller assembly 126 and the traveling roller assembly 125 switch in the transverse and longitudinal directions, the chain transmission assembly 122 can drive the side guide surface of the side guide rail steering assembly 121 to synchronously switch in the transverse and longitudinal directions around the side guide wheel 21;

[0076] If the vehicle loading plate 2 does not move to the center of the steering drive assembly 12, the center of the vehicle loading plate side guide wheel 21 does not coincide with the rotation center of the side guide rail steering assembly 121. If there is a positioning deviation of ≤30 mm between the two (such as Fig.15 and Fig.18 ), when the driven roller assembly 126 and the traveling roller assembly 125 switch from the transverse direction to the longitudinal direction, the chain transmission assembly 122 can drive the side guide surfaces of all the side guide rail steering assemblies 121 to rotate around the side guide wheel 21 (the rotation direction of the four side guide rail steering assemblies 121 is as follows Fig.16 As shown, the side guide wheel 21 is subjected to force as follows Fig.19 As shown), during this process, the side guide rail steering assembly 121 squeezes the side guide wheel 21 to rotate, Fig.16 The side guide steering assembly 121 on the right side of the middle squeezes the side guide wheel 21 to move to the left, and the positioning deviation can be gradually reduced until the side guide steering assembly 121, the driven roller assembly 126 and the travel roller assembly 125 are all rotated to the longitudinal direction, such as Fig.17 As shown, at this time, the positioning deviation is completely eliminated, and the four vehicle-carrying plate side guide wheels 21 are located between the two longitudinal guide rails, so that the subsequent longitudinal movement can be realized; accordingly, if there is a positioning deviation when moving longitudinally to the next vehicle-carrying frame, forced correction can also be performed during the lateral and longitudinal adjustments;

[0077] The present application adds mechanical hard synchronization for forced correction on the basis of positioning of the electrical components of the positioning sensor. The positioning deviation of ≤30mm can be corrected mechanically. The present application does not completely rely on electronic components. When the electronic components are inaccurate, mechanical forced correction can be used to further improve the accuracy of the process of moving the carrier plate to the carrier frame, which is more conducive to promotion.

[0078] The specific operating principles of this application are as follows:

[0079] In the initial state, the vehicle moves onto the vehicle plate 2, which is located at the center of the vehicle frame 1, and all the wheel assemblies and the side guide rail steering assembly 121 in the vehicle frame 1 are in a transverse position, and the side guide wheels 21 of the vehicle plate 2 are accommodated in the transverse guide channel formed by the side guide rail steering assembly 121 and the side guide rail assembly 14; the steering drive assembly of the vehicle frame 1 is started, pushing the vehicle plate 2 to move transversely and drive to another adjacent vehicle frame 1;

[0080] When the vehicle carrier plate 2 moves horizontally to the center position of the adjacent vehicle carrier frame 1 and then stops, the steering drive assembly of the adjacent vehicle carrier frame 1 starts the rotation action, switches all the supporting wheel assemblies and the side guide steering assembly 121 of the vehicle carrier frame 1 to the longitudinal position state, and forcibly corrects the possible positioning deviation of the side guide wheel 21 here, and the side guide wheel 21 of the vehicle carrier plate 2 is accommodated in the longitudinal guide channel formed by the side guide steering assembly 121 and the side guide assembly 14; the steering drive assembly of the vehicle carrier frame 1 is started, pushing the vehicle carrier plate 2 to move longitudinally towards another adjacent vehicle carrier frame 1 until it moves to the designated vehicle carrier frame 1.

[0081] Example 2

[0082] Reference Figure 1 The present embodiment discloses a parking system, including a vehicle lifting frame and several layers of parking mechanisms. The vehicle lifting frame can move the vehicle to the parking mechanism on the designated layer. A set of vehicle carriers 1 and vehicle carrier plates 2 are also arranged on the vehicle lifting frame. Each layer of the parking mechanism includes a vehicle carrier 1 and a vehicle carrier plate 2. The vehicle carriers 1 on each layer are arranged in a rectangular array with several groups. The number of vehicle carrier plates 2 is one group less than the number of vehicle carriers 1. The car is first parked on the vehicle carrier plate 2 on the vehicle lifting frame, and then moved to the designated layer by the vehicle lifting frame. The rear vehicle carrier plate 2 can be moved horizontally or vertically to the designated vehicle carrier 1.

[0083] A plurality of vehicle carriers 1 are arranged in series along a transverse and longitudinal array in a horizontal plane, so that the vehicle carrier plate 2 can be continuously translated in two dimensions transversely / longitudinally above the vehicle carriers 1 .
