Description

Technical Field

[0001] This application relates to the field of automated parking system technology, and in particular to a positioning device for an automated parking system lifting platform. Background Technology

[0002] In existing underground multi-level parking garages, after the lifting platform is level with the parking platform, cars are transported from the lifting platform to the parking platform for parking, or from the parking platform to the lifting platform for retrieval. At this time, the lifting platform uses a braking device to stop the car. There is a safety hazard that the lifting platform is unstable if the brake fails or the braking force is insufficient, which needs to be solved.

[0003] Our company's prior patent application, number 201810744836.0, entitled "Automatic Parking Garage," discloses an automated parking garage that solves the technical problem of poor stability of the lift mechanism during movement in existing automated parking garages. It includes several parking space gateposts, two parking space support columns, a conveying space, several parking space assemblies, parking space canopy crossbeams, several parking space canopy longitudinal beams, upper guide rails, lower guide rails, an outer frame, upper track wheel assemblies, and lower track wheel assemblies. The outer frame has a vertically arranged sliding channel within which a lifting platform is slidably mounted. Several platform conveying assemblies are sequentially arranged along the length of the lifting platform. The lifting platform is connected to a lifting drive structure that drives it to slide up and down within the sliding channel. This patent does not disclose how the parking space and the lift mechanism are locked during vehicle entry and retrieval.

[0004] Another Chinese invention patent, CN201610076475.8, entitled "Multi-level Parking Garage," discloses a system comprising multiple ring-shaped platforms, each divided into multiple parking spaces along its circumference. The central opening of each ring-shaped platform forms a vehicle lifting channel, within which a lifting platform capable of reciprocating vertical movement is installed. The invention is characterized by the ring-shaped platform being composed of at least two sector-shaped units, with each sector-shaped unit having its own independent lifting and transfer mechanism. However, this application also fails to disclose that the lifting platform does not limit its movement relative to the parking space during vehicle access, raising concerns about the platform's instability and potential safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for a multi-level parking garage lifting platform, which can limit the movement of the lifting platform and the parking platform when parking or retrieving vehicles, thereby preventing the lifting platform from shaking up and down and causing damage to the vehicles.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] The automated parking system includes a cylindrical shaft, a parking platform fixedly connected to the shaft wall, a support wall along the depth of the shaft, and a lifting platform for storing and retrieving vehicles. The support wall supports the parking platform. The lifting platform includes a guide rail along the height of the support wall, a lifting arm slidably connected to the guide rail, and a rotary platform rotatably connected to the lifting arm.

[0008] A positioning device for a vertical parking garage lifting platform includes a sliding device and a limiting device disposed between the guide rail and the lifting arm.

[0009] Furthermore, the guide rail is a channel steel; the opening of the channel steel faces the lifting arm, and the sliding device includes a radial guide device that is slidably connected to the bottom surface of the channel steel opening and a circumferential guide device that is slidably connected to the side surface of the channel steel opening.

[0010] Furthermore, the limiting device includes a positioning hole provided on the guide slide, a positioning rod with one end inserted into the positioning hole, a guide sleeve slidably connected to the positioning rod, a connecting rod with one end hinged to the other end of the positioning rod, a turntable hinged to the other end of the connecting rod, and a reducer for driving the turntable to rotate; the edge of the turntable is hinged to the other end of the connecting rod; the guide sleeve is fixedly connected to the lifting arm.

[0011] Furthermore, the radial guide device includes a first pin rotatably connected to the end of the lifting arm and a first roller fixedly connected to the first pin; the first roller abuts against the bottom surface of the channel steel opening.

[0012] Furthermore, the lifting arm is equipped with a bearing, and the first pin is rotatably connected to the lifting arm through the bearing.

[0013] Furthermore, the circumferential guiding device includes a second roller that is rolledly connected to the inner surface of the side of the channel steel, a second pin that is fixedly connected to the second roller, and a bracket that is rotatably connected to the second pin.

[0014] Furthermore, a bearing is provided between the second pin and the bracket.

[0015] The beneficial effects of this application are:

[0016] This application utilizes a limiting device installed between the lifting arm and the guide rail. The limiting device includes a positioning hole on the guide rail, a positioning rod with one end inserted into the positioning hole, a guide sleeve slidably connected to the positioning rod, a connecting rod with one end hinged to the other end of the positioning rod, a turntable hinged to the other end of the connecting rod, and a reducer for driving the turntable to rotate. The edge of the turntable is hinged to the other end of the connecting rod. The guide sleeve is fixedly connected to the lifting arm. When the rotating platform is flush with the parking platform and a vehicle is ready to be stored or retrieved, the reducer (with a motor) rotates, driving the turntable to rotate. The turntable drives the connecting rod to swing, and the connecting rod drives the positioning rod to slide along the guide sleeve. The positioning rod inserts into the positioning hole, the reducer stops rotating, and the positioning rod positions the lifting platform, preventing brake failure of the lifting platform during vehicle storage or retrieval, which could lead to vehicle damage or other safety accidents.

[0017] By using the first and second rollers, the support arm and guide rail are limited when the lifting platform is rising or falling. The first roller prevents the support arm from moving radially, and the two second rollers prevent the support arm from rotating circumferentially. This ensures smooth operation when the lifting platform is rising or falling. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] like Figure 1 As shown in Figure 5,

[0032] The multi-level parking garage includes a cylindrical shaft 4, a parking platform 5 fixedly connected to the wall of the shaft 4, a support wall set along the depth direction of the shaft 4, and a lifting platform for storing and retrieving vehicles. The support wall is used to support the parking platform 4 and divides each parking platform 5 into several parking areas.

[0033] The lifting platform includes a guide slide 3 arranged along the height of the supporting wall, a lifting arm 1 slidably connected to the guide slide 3, and a rotary platform 2 rotatably connected to the lifting arm 1.

[0034] The lifting platform is equipped with three lifting arms, and the support wall is also equipped with three corresponding guide rails 3 to facilitate the up and down movement of the lifting arms 1.

[0035] like Figure 1 As shown, a positioning device for a multi-level parking garage lifting platform includes a sliding device 6 and a limiting device 7 disposed between the guide slide 3 and the lifting arm 1. The sliding device 6 enables the lifting arm 1 to slide within the guide slide 3, thereby achieving the lifting and lowering of the car; the limiting device 7 is used to position the lifting arm 1 relative to the guide slide 3 when parking or retrieving the car.

[0036] like Figure 3 As shown, each lifting arm 1 is equipped with a sliding device 6 and a limiting device 7.

[0037] like Figure 3 As shown, the guide slide 3 is made of channel steel and fixed to the load-bearing support wall; the opening of the channel steel faces the lifting arm 1.

[0038] like Figure 1 , 2 as well as Figure 4As shown, the limiting device 7 includes a positioning hole provided on the guide slide 3, a positioning rod 71 with one end inserted into the positioning hole, a guide sleeve 72 slidably connected to the positioning rod 71, a connecting rod 74 with one end hinged to the other end of the positioning rod 71, a turntable 75 hinged to the other end of the connecting rod 74, and a reducer 76 for driving the turntable 75 to rotate; the edge of the turntable 75 is hinged to the other end of the connecting rod 74; the guide sleeve 72 is fixedly connected to the lifting arm 1.

[0039] In detail, each parking platform 5 has a positioning hole on its corresponding guide rail 3, which allows the positioning rod 71 to position the lifting platform relative to the channel steel when parking or retrieving vehicles on that floor. The positioning rod 71 and the connecting rod 74 are rotatably connected via a hinge shaft 73. The connecting rod 74 and the turntable 75 are rotatably connected via a rod end bearing.

[0040] The sliding device 6 includes a radial guide device that is slidably connected to the bottom surface of the channel steel opening and a circumferential guide device that is slidably connected to the two sides of the channel steel opening. The radial and circumferential guide devices prevent the lifting arm 1 from swaying inside the channel steel, thus avoiding instability during lifting.

[0041] like Figure 5 As shown, the radial guide device includes a first pin 62 rotatably connected to the end of the lifting arm 1 and a first roller 61 fixedly connected to the first pin 62; the first roller 61 abuts against the bottom surface of the channel steel opening.

[0042] The lifting arm 1 is equipped with a bearing, and the first pin 62 is rotatably connected to the lifting arm 1 through the bearing.

[0043] The circumferential guiding device includes a second roller 63 that is rolledly connected to the inner side surface of the channel steel, a second pin 65 that is fixedly connected to the second roller 63, and a bracket 64 that is rotatably connected to the second pin 65; the bracket 64 is fixed on the lifting arm 1; thus the two second rollers 63 are rolledly connected to the side wall of the channel steel.

[0044] A bearing is provided between the second pin 65 and the bracket 64.

[0045] When the lifting platform is raised or lowered, the two second rollers 63 and one first roller 61 roll on the bottom and two sides of the channel steel, changing the sliding friction to rolling friction, reducing friction, and allowing the lifting platform's drive device to reduce power and save energy.

[0046] The working process of this application,

[0047] When a vehicle needs to be parked or retrieved, the rotating platform 2 of the lifting platform is aligned with the parking platform 5. At this time, the reducer 76 (with motor) is started. The reducer 76 rotates, driving the turntable 75 to rotate. The turntable 75 drives the connecting rod 74 to swing, and the connecting rod 74 drives the positioning rod 71 to move linearly along the positioning sleeve 72. The positioning rod 71 is inserted into the positioning hole of the channel steel, and the reducer 75 stops rotating to prevent the lifting arm 1 from swaying up and down.

[0048] Example 2

[0049] This embodiment has a basically the same structure as Embodiment 1.

[0050] The difference is that,

[0051] like Figure 6 As shown,

[0052] One end of the connecting rod 74 is provided with an external thread, and the edge of the turntable 75 is provided with a positioning shaft 78. The rod end of the rod end spherical bearing 77 is fixedly connected to the external thread of the connecting rod 74. The positioning shaft 78 is inserted into the bearing hole of the spherical bearing 77 to realize the hinge connection between the connecting rod 74 and the turntable 75.

[0053] By using the spherical bearing 77, the connecting rod 74 can rotate even when there is a slight misalignment between it and the positioning shaft 78 on the turntable 75, which can reduce manufacturing difficulty and manufacturing cost.

[0054] Example 3

[0055] This embodiment has a basically the same structure as Embodiment 1.

[0056] The difference is that,

[0057] The automated parking system is equipped with a PLC control system. A limit proximity switch 8 is located on the back of the guide slide 3. Both the motor of the reducer 75 and the limit proximity switch 8 are connected to the PLC control system. When the positioning rod 71 extends out of the positioning hole, the limit proximity switch 8 senses the signal and transmits it to the control system. The control system then sends a stop signal to the motor. A proximity switch is located on the rotary platform 2. When the rotary platform 2 is aligned with the parking platform 5, the lifting platform stops lifting. The proximity switch transmits a signal to the control system, which then sends a signal to the motor. The reducer 76 rotates, and the turntable 75 drives the positioning rod 71 to insert into the positioning hole of the channel steel. The limit proximity switch 8 then sends a signal, and the control system sends a stop signal to the motor.
