Description

Technical Field

[0001] This utility model relates to the field of stacker positioning technology for aisle-type stacking mechanical automated parking systems, specifically to a stacker positioning mechanism for aisle-type stacking mechanical automated parking systems. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of urban motor vehicle ownership, parking space resources are becoming increasingly scarce. Lane stacking mechanical automated parking garages have become the mainstream solution to alleviate parking difficulties due to their high space utilization rate. As the core execution component of automated parking garages, the accuracy of the stacker crane's positioning mechanism directly affects vehicle parking efficiency, while its stability is related to parking safety. Therefore, stringent requirements are placed on the horizontal movement, lifting positioning accuracy, and operational stability of the positioning mechanism.

[0003] A search revealed that the existing technology (application number: CN202222377259.0) describes "a reading head mounting bracket and a stacker crane with a magnetic grating." Although this utility model improves the reliability of magnetic grating positioning by optimizing the reading head mounting structure, it does not involve a horizontal movement detection structure, a limiting mechanism, or a guiding structure. As a result, the stacker crane can only achieve positioning in a single direction, lacks an effective means of detecting the horizontal movement distance, and the load-bearing components are prone to displacement during lifting and lowering, resulting in insufficient parking stability. This makes it difficult to meet the high precision and high safety requirements of densely parked automated parking systems.

[0004] Therefore, there is an urgent need for a stacker crane positioning mechanism that combines precise horizontal and vertical positioning with stable operation. Utility Model Content

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, the stacker positioning mechanism of the lane stacking mechanical parking garage provided in this embodiment includes: a base 1, the upper surface of the slider is connected to both sides of the lower surface of the base 1, and the two ends of the opposite side of the slider are rotatably connected to one side of the roller, a slide rail assembly 2 is provided below the base 1, the slide rail assembly 2 is used for the sliding of the base 1, multiple sets of guide support columns 4 are provided around the upper surface of the base 1, the lower end of the guide support column 4 is connected to the upper surface of the base 1, and the guide support column 4 on both sides of the upper surface of the base 1 is provided with a sliding groove on the opposite side, the end of the guide support column 4 away from the base 1 is connected to the lower surface of the mounting plate 6, and two sets of positioning components 5 are provided on both sides of the middle of the upper surface of the base 1.

[0033] In this embodiment, the slide rail assembly 2, the bearing assembly 3, the positioning assembly 5, and the lifting mechanism 7 constitute the stacker positioning mechanism of the lane stacking mechanical automated parking system involved in this application.

[0034] It should also be noted that the lane-stacking mechanical automated parking system in this application can be a double-column lane-stacking parking system, a single-column lane-stacking parking system, a bridge-type lane-stacking parking system, etc. Figure 1 In this embodiment, a double-column type of lane stacking mechanical parking garage is used as an example for description. Of course, other types of lane stacking mechanical parking garages can also adopt similar structures, which will not be elaborated on later.

[0035] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the stacker crane positioning mechanism; the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, the stacker crane positioning mechanism can also include, compared to... Figure 1 More or fewer parts.

[0036] In addition, in this embodiment, the base 1 moves horizontally through the slider and roller in conjunction with the slide rail assembly 2, and the guide support column 4 provides vertical support to ensure the stability of the mechanism's foundation sliding and support.

[0037] Specifically, one end of the positioning component 5 is connected to the upper surface of the base 1, and the other end of the positioning component 5 away from the base 1 is connected to the lower surface of the mounting plate 6. A bearing component 3 and a lifting mechanism 7 are provided between the upper surface of the base 1 and the lower surface of the mounting plate 6. The bearing component 3 is used to support the vehicle, and the lifting mechanism 7 is used to lift the bearing component 3.

[0038] In this embodiment, the positioning component 5 assists in positioning, the bearing component 3 supports the vehicle, and the lifting mechanism 7 provides lifting power, thereby achieving an orderly connection between vehicle bearing and lifting actions.

[0039] Example 2:

[0040] Based on embodiment 1, a slide rail assembly 2 is provided.

[0041] Specifically, the slide rail assembly 2 includes a track 201, which is provided in two sets and distributed on both sides of the lower surface of the base 1. A slide groove is provided in the middle of the upper surface of the track 201, and a slider on the lower surface of the base 1 is slidably connected in the slide groove. A placement groove 202 is provided on the side of the bottom surface of the slide groove away from the slider.

[0042] In a preferred embodiment, the slider slides within the groove of the track 201, and the placement groove 202 accommodates the matching components, providing a stable horizontal movement trajectory for the base 1 and ensuring smooth sliding.

[0043] Specifically, an optical fiber sluice 203 is placed inside the placement slot 202, and a cover plate 204 is provided above the optical fiber sluice 203. The outer walls on both sides of the cover plate 204 are connected to the inner walls on both sides above the placement slot 202, and the surface of the cover plate 204 away from the optical fiber sluice 203 abuts against the lower surface of the roller.

[0044] In this embodiment, a quartz fiber optic cable 203 is placed inside the placement slot 202. A stainless steel cover plate 204 is placed above the fiber optic cable 203. The two ends of the fiber optic cable 203 are connected to a light source transmitter (not shown in the figure) and a light signal receiver (not shown in the figure), respectively. When the base 1 drives the roller to roll along the upper surface of the cover plate 204, the weight of the roller and the pressure of the base 1 cause the cover plate 204 to undergo elastic deformation into the placement slot 202. The lower surface of the cover plate 204 presses the fiber optic cable 203, causing the fiber optic cable 203 in the pressure area to bend locally. When the fiber optic cable 203 bends, the optical power detected by the receiver decreases synchronously with the degree of bending. The controller receives the power change data of the light signal receiver. Based on the correspondence between the bending curvature of the fiber optic cable 203 and the optical leakage, combined with parameters such as the roller diameter and the deformation stroke of the cover plate, the controller converts the number of periodic signal fluctuations and the fluctuation amplitude into the actual horizontal movement distance of the base 1, thereby achieving accurate detection of the horizontal movement distance of the base 1.

[0045] Specifically, the bearing assembly 3 includes a bearing plate 301. The two ends of the two side walls of the bearing plate 301 are rotatably connected to one side of the guide wheel 302. The rolling surface of the guide wheel 302 rolls in the groove on the opposite side of the guide support column 4. Two sets of first electromagnets 303 are provided on the two side walls in the middle of the bearing plate 301. The opposite side of the first electromagnet 303 is connected to the side wall of the bearing plate 301, and the side of one side wall of the bearing plate 301 away from the first electromagnet 303 is connected to one side of the reading head 304.

[0046] With this configuration, the guide wheel 302 rolls along the groove to provide guidance, the first electromagnet 303 provides attraction force, and the reading head 304 detects the position, ensuring accurate lifting and guiding of the bearing component 3 and position signal feedback.

[0047] Example 3:

[0048] A positioning component 5 is provided based on embodiment 2.

[0049] Specifically, the positioning component 5 includes a support plate 501, which is provided in two sets. The support plate 501 has multiple grooves arranged vertically on one side. A second electromagnet 502 is installed in the groove. The side wall of one set of support plates 501 away from the second electromagnet 502 is connected to one side of a magnetic scale 503. The side wall of the magnetic scale 503 away from the support plate 501 is slidably connected to the side of the reading head 304 away from the support plate 301.

[0050] Among them, the magnetic grating ruler 503 is a bar-shaped magnetic sensitive material component that records alternating magnetic grating signals at equal intervals along the vertical direction. The reading head 304 is a photoelectric sensing component with built-in excitation coil and detection coil. After the reading head 304 is energized, the N pole and S pole of the magnetic grating ruler 503 are alternately distributed to form a regular magnetic resistance change. When the reading head 304 slides along the magnetic grating ruler 503, the detection coil senses the periodic fluctuation of the magnetic flux and converts it into an alternating voltage signal corresponding to the magnetic grating spacing. According to the preset grating spacing parameters of the magnetic grating ruler 503, the actual moving distance of the reading head 304, i.e. the lifting height of the bearing component 3, is calculated through the counting and phase recognition of the pulse signal. The reading head 304 slides along the magnetic grating ruler 503 to detect the height. The first electromagnet 303 and the second electromagnet 502 are energized and attracted to each other, realizing the precise positioning and stable limit of the bearing component 3.

[0051] Specifically, the lifting mechanism 7 includes a dual-head motor 701, which is installed in the middle of the upper surface of the mounting plate 6. The output shafts on both sides of the dual-head motor 701 are respectively connected to two sets of sprockets 702. A chain 703 is provided on the outside of the sprockets 702, and a pulley 704 is provided below the sprockets 702. The pulley 704 is rotatably connected to the lower side of the opposite side of the support plate 501. One end of the chain 703 is connected to the upper side of the two side walls of the bearing plate 301, and the end of the chain 703 away from the bearing plate 301 passes around the sprockets 702 and then connects to the lower side walls of the two side walls of the bearing plate 301 after connecting with the pulley 704.

[0052] In this embodiment, the dual-head motor 701 drives the sprocket 702 to rotate, and the chain 703 guides the bearing plate 301 to rise and fall through the pulley 704, so as to realize the smooth and synchronous lifting of the bearing component 3.

[0053] In actual use, the vehicle is first moved to the upper surface of the bearing assembly 3 by the vehicle clamp (not shown in the figure) on the upper surface of the bearing assembly 3. Then, the base 1 is slid inside the upper surface of the slide rail assembly 2. At this time, the roller on the lower surface of the base 1 rolls on the upper surface of the cover plate 204. When the roller passes, the cover plate 204 presses the fiber optic cable 203, causing the fiber optic cable 203 to bend, thereby detecting the moving distance of the base 1. After moving to the appropriate position, the vehicle is moved to the appropriate position.

[0054] When the dual-head motor 701 is started, the output shaft of the dual-head motor 701 drives the sprocket 702 to rotate. The rotation of the sprocket 702 drives the chain 703 to move. The movement of the chain 703 drives one end of the chain 703 to lift the bearing component 3. At this time, the other end of the chain 703 is also connected to the bearing component 3. Therefore, through the rotation guidance of the pulley 704, the bearing component 3 drives the other end of the chain 703 to rise. While the bearing component 3 rises, the guide wheels 302 around the bearing component 3 roll in the groove on the opposite side of the guide support column 4 for guidance.

[0055] During the ascent of the support plate 301, the reading head 304 on one side wall of the support plate 301 slides on one side of the magnetic scale 503. The ascent height of the support plate 301 is detected by the sliding height of the reading head 304 across the magnetic scale 503. After moving to the appropriate height, the first electromagnets 303 on both side walls of the support plate 301 are energized. After the first electromagnets 303 are energized, they attract the second electromagnet 502 in the groove on one side of the support plate 501 and slide along the inside of the groove. Then, the side of the support plate 501 away from the support plate 301 aligns with the side of the second electromagnet 502 to maintain the height stability of the support plate 301. Then, the vehicle can be moved into the parking space.

[0056] The dual-head motor 701 is electrically connected to the controller, which is electrically connected to an external power supply. The controller allows for convenient power control of the electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0057] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
