Description
Technical Field
[0001] This invention relates to the field of automated parking systems, and particularly to an anti-deviation structure for a chain traction system in an automated parking system. Background Technology
[0002] The principle of an automated parking system is to use mechanical devices to park vehicles in a three-dimensional space, thereby achieving efficient use of land resources. During the operation of an automated parking system, the chain traction system is a crucial component, responsible for lifting, lowering, or moving the vehicle platform. However, in practical applications, the chain may be affected by various factors during operation, such as uneven weight distribution of the vehicle platform and changes in chain tension, leading to chain misalignment. This misalignment not only affects the normal operation of the automated parking system but may also damage vehicles and equipment. Therefore, during the assembly of the traction system, an anti-misalignment structure is required to limit chain displacement and ensure that the vehicle platform moves smoothly during operation.
[0003] Existing anti-deviation structures for chain traction systems in automated parking garages mostly rely on a single limiting component to constrain the chain. This structure lacks flexibility in handling complex and changing operating environments, and cannot be adjusted to accommodate different models of automated parking garages, varying chain specifications, and operational requirements. Therefore, this application provides an anti-deviation structure for chain traction systems in automated parking garages to meet these requirements. Summary of the Invention
[0004] To address the aforementioned issues, this application provides an anti-deviation structure for a chain traction system in a multi-level parking garage.
[0005] To achieve the above objectives, this application provides the following technical solution: an anti-deviation structure for a chain traction system of a three-dimensional parking garage, comprising a support frame as the mounting and bearing component of the entire anti-deviation structure, two limiting frames fixed to the inner side of the support frame in a symmetrical structure, and two sets of anti-deviation components correspondingly assembled to the inner side of the two limiting frames.
[0006] Each anti-deviation assembly includes a first limiting bracket, a first limiting roller group disposed within the first limiting bracket, a second limiting bracket symmetrically distributed with the first limiting bracket, and a second limiting roller group disposed within the second limiting bracket. The chain used to pull the vehicle platform can pass through the inner sides of the two limiting frames, and the chain is located between the first limiting roller group and the second limiting roller group.
[0007] The two sets of first and second limit supports can be adjusted synchronously to adjust the distance between them, thereby adjusting the distance between limit roller group one and limit roller group two.
[0008] Furthermore, each of the two first limiting supports has a linkage plate fixed on one side, and the linkage plates extend through the limiting frame to the inside of the support frame. The end of the linkage plate away from the first limiting support is fixed with a guide slider.
[0009] A first push arm and a second push arm are respectively installed on the two guide sliders. The ends of the first push arm and the second push arm away from the guide slider are both installed on the same positioning shaft. A movable push block is fixed at the bottom end of the positioning shaft. As the push block moves, the first push arm and the second push arm respectively push the two sets of guide sliders, the linkage plate and the first limit support to move.
[0010] Furthermore, the support frame is equipped with a drive screw, a drive handle that can drive the drive screw to rotate, and guide rods distributed on both sides of the drive screw. The push block is installed on the drive screw, and bushings are fixed on both sides of the push block. The two bushings are slidably fitted onto the two guide rods respectively.
[0011] Furthermore, a connecting plate is fixed inside the support frame, and a horizontally distributed second guide rail is fixed on the side of the connecting plate opposite the guide slider. Both guide sliders are slidably assembled on the second guide rail.
[0012] Furthermore, a first slide bar and a second slide bar are fixed to the front and rear sides of the first limiting bracket and the second limiting bracket, respectively. The second slide bar is located below the first slide bar, and a first linkage rack and a second linkage rack are fixed to the opposite sides of the first slide bar and the second slide bar, respectively. The same drive gear is meshed in the relative space of the first linkage rack and the second linkage rack. The drive gear is assembled inside the support frame. When the first slide bar moves with the first limiting bracket, the first linkage rack drives the drive gear to rotate, so that the second limiting bracket moves closer to or away from the first limiting bracket synchronously.
[0013] Furthermore, a set of horizontally distributed first guide rails are fixed on the front and rear walls of the limiting frame, and the first and second slide bars are slidably assembled on the first guide rails.
[0014] Furthermore, positioning plates are fixed on both the front and rear walls of the limiting frame, and the driving gears are installed inside the gap between the positioning plates and the walls of the limiting frame.
[0015] In summary, the technical effects and advantages of this invention are as follows:
[0016] 1. This invention enables the chain to be stably limited during operation, effectively preventing chain deviation when traction of the vehicle platform. Furthermore, the distance between the first and second limiting roller groups can be quickly adjusted according to actual needs, further enhancing the flexibility and adaptability of the anti-deviation structure and ensuring the chain is always in the optimal limiting state.
[0017] 2. The present invention, through adjustable spacing limit roller group one and limit roller group two, facilitates cleaning operations without affecting the chain. The entire process does not require additional disassembly steps, greatly saving cleaning time and labor costs, improving the maintenance efficiency of the chain traction system of the three-dimensional parking garage, and also improving the operational stability of the entire anti-deviation structure.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Example 1: Reference Figure 1-3 The anti-deviation structure for a chain traction system of a three-dimensional parking garage shown includes a support frame 1, which serves as the mounting and bearing component of the entire anti-deviation structure; two limiting frames 2 fixed to the inner side of the support frame 1 in a symmetrical structure; and two sets of anti-deviation components correspondingly assembled to the inner side of the two limiting frames 2.
[0029] Each anti-deviation assembly includes a first limiting support 3, a first limiting roller group 31 disposed within the first limiting support 3, a second limiting support 4 symmetrically distributed with the first limiting support 3, and a second limiting roller group 41 disposed inside the second limiting support 4. See Figure 3 As shown, the chain used for traction of the vehicle platform can be threaded through the inner sides of the two limiting frames 2, and the chain is located between the first limiting roller group 31 and the second limiting roller group 41. The setting of the first limiting roller group 31 and the second limiting roller group 41 ensures that the chain is stably limited during operation, effectively preventing the chain from deviating when traction of the vehicle platform.
[0030] Furthermore, the two sets of first limit support 3 and second limit support 4 can synchronously adjust the distance between them, thereby adjusting the distance between limit roller group 1 31 and limit roller group 2 41. Therefore, in this application, the distance between limit roller group 1 31 and limit roller group 2 41 can be quickly adjusted according to actual needs, further enhancing the flexibility and adaptability of the anti-deviation structure and ensuring that the chain is always in the optimal limit state.
[0031] Simultaneously, by adjusting the distance between the two sets of limiting roller groups 31 and 41, cleaning operations can be performed on both groups. Specifically, after adjusting the distance, workers only need to use appropriate cleaning tools, such as a soft brush or cleaning cloth, to wipe the surfaces of the limiting roller groups 31 and 41 to remove dust, oil, and other impurities adhering to the roller groups, thus ensuring the cleanliness of the limiting roller groups, allowing them to rotate smoothly, and extending their service life. The entire process requires no additional disassembly steps, greatly saving cleaning time and labor costs, improving the maintenance efficiency of the automated parking system's chain traction system, and also enhancing the operational stability of the entire anti-deviation structure.
[0032] like Figure 4As shown in this application, each of the two first limiting supports 3 has a linkage plate 6 fixed on one side. The linkage plate 6 extends through the limiting frame 2 to the inside of the support frame 1, and the end of the linkage plate 6 away from the first limiting support 3 is fixed with a guide slider 7.
[0033] A first push arm 8 and a second push arm 9 are respectively installed on the two guide sliders 7. The ends of the first push arm 8 and the second push arm 9 away from the guide sliders 7 are both installed on the same positioning shaft 10. A movable push block 11 is fixed at the bottom of the positioning shaft 10. As the push block 11 moves, the first push arm 8 and the second push arm 9 respectively push the two sets of guide sliders 7, the linkage plate 6 and the first limit support 3 to move.
[0034] Specifically, such as Figure 5 , Figure 6 As shown, in order to drive the push block 11 to move, in this application, the support frame 1 is equipped with a drive screw 13, a drive handle 15 that can drive the drive screw 13 to rotate, and guide rods 14 distributed on both sides of the drive screw 13. The push block 11 is installed on the drive screw 13, and bushings 12 are fixed on both sides of the push block 11. The two bushings 12 are slidably mounted on the two guide rods 14 respectively.
[0035] like Figure 7 As shown, during operation, the operator only needs to control the drive handle 15 to rotate on the outside of the support frame 1, which will drive the drive screw 13 to rotate. Since the push block 11 is installed on the drive screw 13 and has bushings 12 on both sides that slide in contact with the guide rod 14, the rotation of the drive screw 13 will cause the push block 11 to move linearly along the guide rod 14. When the push block 11 moves, it will drive the positioning shaft 10 to move, and the positioning shaft 10 will drive the first push arm 8 and the second push arm 9 to move. The first push arm 8 and the second push arm 9 will respectively push the two sets of guide sliders 7 to slide along the second guide rail 17. The sliding of the guide sliders 7 will drive the linkage plate 6 to move, and the movement of the linkage plate 6 will in turn drive the first limit support 3 to move, so as to adjust the distance between the first limit support 3 and the chain. Furthermore, when the first limit support 3 and the limit roller group 31 are away from the chain, the limit roller group 31 can be cleaned.
[0036] In this application, as Figure 6 As shown, in order to maintain the stability of the guide slider 7 during its movement, a connecting plate 16 is fixed to the inner side of the support frame 1. A horizontally distributed second guide rail 17 is fixed to the connecting plate 16 on the side opposite to the guide slider 7, and both guide sliders 7 are slidably mounted on the second guide rail 17. Therefore, when the two guide sliders 7 move in opposite directions, the guide sliders 7 actually move along the distribution path of the second guide rail 17.
[0037] Example 2: Based on Example 1, such as Figure 5-7As shown, the first limiting support 3 and the second limiting support 4 are respectively fixed with a first slide bar 32 and a second slide bar 42 on the front and rear sides. The second slide bar 42 is located below the first slide bar 32, and the first linkage rack 33 and the second linkage rack 43 are respectively fixed on the opposite sides of the first slide bar 32 and the second slide bar 42. The same drive gear 5 is meshed in the relative space of the first linkage rack 33 and the second linkage rack 43. The drive gear 5 is assembled on the inner side of the support frame 1.
[0038] When the first slide bar 32 moves with the first limiting support 3, the first linkage rack 33 drives the drive gear 5 to rotate. At the same time, the drive gear 5 rotates and drives the second linkage rack 43 to move. Since the second linkage rack 43 is fixed on the second slide bar 42 and the second slide bar 42 is connected to the second limiting support 4, the second limiting support 4 will move closer to or further away from the first limiting support 3 in sync with the movement of the second linkage rack 43.
[0039] By adjusting synchronously, the first limit support 3 and the second limit support 4 are always symmetrically distributed during movement, which ensures that the distance between the first limit roller group 31 and the second limit roller group 41 can be precisely adjusted, effectively preventing the chain from deviating when pulling the vehicle platform.
[0040] Furthermore, once the first set of limit rollers 31 and the second set of limit rollers 41 have moved away from the chain simultaneously, the second set of limit rollers 41 can be quickly cleaned. Workers can use a dedicated cleaning brush or compressed air to thoroughly clean the surfaces of each roller and the gaps between them, removing dust, oil, and other impurities accumulated during long-term operation. During the cleaning of the first set of limit rollers 31 and the second set of limit rollers 41, there is no need to move the chain, reducing cleaning blind spots and improving the portability and comprehensiveness of the cleaning operation.
[0041] After cleaning, the drive screw 13 is adjusted again by the drive handle 15 so that the first limit bracket 3 and the second limit bracket 4 approach the chain synchronously, restoring the initial limit state and ensuring that the chain can be stably passed between the first limit roller group 31 and the second limit roller group 41, continuing to limit the chain of the automated parking system.
[0042] In this application, as Figure 1 As shown, to maintain the stability of the first slider 32 and the second slider 42 during movement, a set of horizontally distributed first guide rails 21 are fixed on the front and rear walls of the limiting frame 2, and the first slider 32 and the second slider 42 are slidably mounted on the first guide rails 21. When the first slider 32 and the second slider 42 move in opposite directions, they both move along the distribution path of the first guide rails 21.
[0043] like Figure 7As shown, in order to maintain the stability of the drive gear 5 and reduce the interference of dust and impurities on the drive gear 5, positioning plates 22 are fixed on the front and rear walls of the limiting frame 2, and the drive gear 5 is installed inside the gap between the positioning plate 22 and the wall of the limiting frame 2.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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.
