Abstract
Description
Technical Field
[0001] This invention relates to the field of automated parking system technology, and in particular to a detection device and method for preventing derailment in vertical circulation parking systems. Background Technology
[0002] Among the classifications of automated parking systems, vertical circulation parking systems, occupying only two ground-level parking spaces, can accommodate a larger number of vehicles by utilizing the upper level space. With advantages such as small footprint, high vehicle capacity, short average retrieval time, and reliable structure, they have become the most widely used automated parking systems on the market. Vertical circulation parking systems use suspended baskets to store vehicles. Driven by a circulating chain, the baskets rotate along a circulating guide rail to achieve vehicle storage and retrieval. Although vertical circulation parking systems are equipped with anti-derailment structures, there is still a risk that the basket guide wheels may damage or fail to engage with the guide rail during the basket's movement. If this happens, continued operation of the parking system can cause the basket to tilt, potentially leading to vehicle overturning and posing a significant safety hazard. Summary of the Invention
[0003] The purpose of this invention is to provide a vertical circulating garage anti-derailment detection device and detection method, which can detect abnormalities in the garage operation before the suspended basket becomes tilted or loses its guiding function, and promptly stop the garage to avoid safety accidents.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vertical circulating garage anti-derailment detection device, comprising several suspended baskets and two sets of guide rails arranged at the front and rear of the garage. Each set of guide rails includes two circulating guide rails arranged symmetrically on the left and right sides, with a gap between the two circulating guide rails. Guide rollers are installed at both ends of the suspended baskets, and the guide rollers roll within the circulating guide rails. Detection devices are respectively installed at the upper and lower ends of the circulating guide rails. The detection device includes a mounting frame, which is fixedly connected to the outside of the circulating guide rails. A controller and a detection switch are installed on the mounting frame. The detection switch is electrically connected to the controller. The detection switch detects whether the guide rollers have entered the circulating guide rails and transmits the detection signal to the controller.
[0005] Optionally, the detection switch is a limit switch with a detection swing arm. The end of the circulating guide rail has a through hole that matches the detection swing arm, and the detection swing arm passes through the through hole and is set inside the circulating guide rail.
[0006] Optionally, the circulating guide rail includes a main guide rail and an auxiliary guide rail, and detection devices are provided at the ends of both the main guide rail and the auxiliary guide rail.
[0007] Optionally, it also includes a switch conduit, which is fixedly connected to the garage frame.
[0008] A method for detecting derailment prevention in a vertical circulation parking garage, the method using the aforementioned vertical circulation parking garage derailment prevention detection device, the method comprising at least the following steps:
[0009] 1) When the garage is in operation, the suspended platform will move in a cycle. The guide rollers on the suspended platform will roll along the circulating guide rail. When the suspended platform moves to the top or bottom position, the guide rollers need to move from the circulating guide rail on one side to the circulating guide rail on the other side.
[0010] 2) If all the guide rollers of the top and bottom suspended baskets are in the circulating guide rail on the other side, the detection switch will receive a signal, and all detection switches will transmit the detection signal to the controller. The movement of the suspended basket is normal, and the garage is operating normally. If one or more detection switches do not receive a signal while the top and bottom suspended baskets are in motion, and some controllers do not receive the detection signal transmitted by the detection switch, the garage will stop operating immediately.
[0011] Optionally, in step 2), if the guide rollers in the top and bottom baskets do not enter the circulating guide rail on the other side, the detection switch may not receive a signal. If some controllers do not receive the detection signal transmitted by the detection switch, the garage will stop operating immediately.
[0012] Optionally, in step 2), if the top and bottom baskets move normally, but the guide wheels on the baskets are lost, the detection switch in the circulating guide rail does not receive a signal, and some controllers do not receive the detection signal transmitted by the detection switch, then the garage will stop operating immediately.
[0013] The vertical circulation garage anti-derailment detection device and detection method of the present invention have the following advantages:
[0014] (1) A detection device is installed at the end of the circulating guide rail. The detection switch detects whether the guide roller of the suspended basket enters the circulating guide rail, thereby determining whether the movement trajectory of the suspended basket is normal. The detection result determines whether the garage should continue to operate, thereby achieving the purpose of safe and stable operation of the garage.
[0015] (2) Detection devices are installed on both the main guide rail and the auxiliary guide rail of the circulating guide rail, which can improve the accuracy of the detection results.
[0016] (3) Switch conduit is used for electrical wiring to avoid cable tangling and affecting the normal operation of the garage. Attached Figure Description

[0023] The invention will now be further described with reference to the accompanying drawings.
[0024] like Figures 1-6 As shown, a vertical circulating parking garage anti-derailment detection device includes several suspended baskets 1, switch conduits 2, and two sets of guide rails arranged at the front and rear of the parking garage. Each set of guide rails includes two circulating guide rails 3 arranged symmetrically on the left and right sides, with a gap between the two circulating guide rails 3. Each circulating guide rail 3 includes a main guide rail 4 and an auxiliary guide rail 5. Several guide rollers 6 are installed at both ends of the suspended baskets 1, and the guide rollers 6 roll inside the circulating guide rails 3. Detection devices 7 are installed at both the upper and lower ends of the main guide rail 4 and the auxiliary guide rail 5 of the circulating guide rails 3. The detection device 7 includes a mounting frame 8, which is fixedly connected to the outside of the circulating guide rail 3. A controller (not shown in the figure) and a detection switch are installed on the mounting frame 8. The detection switch is electrically connected to the controller and detects whether the guide rollers 6 enter the circulating guide rail 3 and transmits the detection signal to the controller.
[0025] The detection switch can be, but is not limited to, limit switches, proximity switches, position switches, sensors, and other detection devices. In this embodiment, the detection switch is a limit switch 9, and the controller and the limit switch 9 are electrically connected. A detection swing arm 10 is provided on the limit switch 9, and a through hole 11 matching the detection swing arm 10 is opened at the end of the circulating guide rail 3. The detection swing arm 10 passes through the through hole 11 and is disposed inside the circulating guide rail 3. The switch conduit 2 is fixedly connected to the garage frame for electrical wiring, cable management, and to prevent excessive cable tangling, which could affect the normal operation of the garage.
[0026] A method for detecting derailment prevention in a vertical circulation parking garage, the method using the aforementioned vertical circulation parking garage derailment prevention detection device, the method comprising at least the following steps:
[0027] 1) When the garage is in operation, the suspended basket 1 will perform clockwise or counterclockwise circular motion. The left guide roller 6 on the left side of the suspended basket 1 will roll along the left circular guide rail 3. The right guide roller 6 on the right side of the suspended basket 1 will roll along the right circular guide rail 3. When the suspended basket 1 moves to the top or bottom position, it needs to change position. The guide roller 6 needs to move from one side of the circular guide rail 3 to the other side of the circular guide rail 3.
[0028] 2) Taking the clockwise direction of the garage as an example, the top basket 1 needs to move from the left circulation guide rail 3 to the right circulation guide rail 3, and the bottom basket 1 needs to move from the right circulation guide rail 3 to the left circulation guide rail 3. In this case, the detection signals of the upper right and lower left position detection devices 7 are used as the basis for judgment.
[0029] If the guide rollers 6 in the top and bottom suspended baskets 1 all enter the circulating guide rail 3 on the other side, the guide rollers 6 will move the detection swing arm 10 in the circulating guide rail 3, and all limit switches 9 will transmit the detection signal to the controller. The controller will determine that the movement of the suspended basket 1 is normal and the garage is operating normally.
[0030] If, during the position change of the top and bottom suspended baskets 1, the detection swing arm 10 is not moved, some controllers will not receive the detection signal transmitted by the limit switch 9, and the garage will immediately stop operating. There are two main reasons for this: First, one or more guide rollers 6 on the top and bottom suspended baskets 1 may not be engaged in the circulating guide rail 3 on the other side. These guide rollers 6 cannot make normal contact with the detection swing arm 10, and the corresponding controllers will not receive the detection signal transmitted by the limit switch 9. If the garage continues to operate, the suspended basket 1 may tilt, posing a risk of vehicle overturning. Therefore, the controller will immediately stop the garage operation.
[0031] The second scenario is that the top and bottom suspended baskets 1 move normally, but due to issues such as broken rollers, the guide rollers on the suspended basket 1 are lost. This will also cause the guide rollers 6 to fail to make normal contact with the detection swing arm 10, and the corresponding controller will not receive the detection signal transmitted by the limit switch 9. Although this situation will not cause the suspended basket 1 to tilt, the lack of cooperation between the guide rollers 6 and the circulating guide rail 3 will compromise the stability of the lifting and lowering of the suspended basket 1. Therefore, the controller will immediately stop the operation of the garage.
[0032] When the garage is running counterclockwise, the detection signals from the upper left and lower right position detection devices 7 are used as the basis for judgment, and the detection method is the same.
[0033] The detection device 7 can detect whether the guide roller 6 of the suspended basket 1 enters the circulating guide rail 3, and thus determine whether the operation of the suspended basket 1 is normal, thereby achieving the purpose of safe and stable operation of the garage.
[0034] The embodiments described above are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the protection scope of the present invention.
