Description

Technical Field

[0001] This application relates to the field of automated parking system technology, and in particular to an auxiliary support structure for a rotating platform of an automated parking system. Background Technology

[0002] Our company sells and installs underground automated parking systems, such as... Figure 4 As shown, after a period of use, the customer reported that the edge of the turntable was slightly sagging. After observation by the technicians, it was found that this was because the edge of the turntable was suspended in the air and the edge of the platform was weak, which needed to be resolved.

[0003] Our company's prior patent application, number 2023233018617, entitled "A Rotating Platform for a Multi-Level Parking Garage," discloses a rotating structure including a rotating platform and a lifting device. The vertical shaft has limiting devices at its bottom and top for vertically limiting the lifting device and the rotating platform. The rotating structure includes a bearing between the lifting device and the rotating platform, and a power device for driving the rotating platform to rotate. The lifting device has a first flange welded to it, which is fixedly connected to the outer ring of the bearing. The rotating platform includes a tube body and a second flange fixedly connected to the tube body, which is fixedly connected to the inner ring of the bearing. The power device includes a spindle box, a main shaft, a geared motor, a gear, and a gear ring; the gear meshes with the gear ring. The rotating platform in this patent has an overhanging edge, which leads to sagging after a period of use.

[0004] There is also a Chinese invention patent with patent number 200610086606.7, which discloses a cylindrical combined high-density three-dimensional parking garage that uses a lifting and rotating platform to transport vehicles for parking or retrieval. The edge of the rotating platform is also suspended in the air, so this application also has the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary support structure for a rotary platform in a three-dimensional parking garage, which can support the edges of the rotary platform and prevent deformation of the edges after long-term use.

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

[0007] The rotary platform of the automated parking garage includes three lifting arms evenly distributed along the circumference of the central cylinder, a rotary platform rotatably connected to the central cylinder, and a drive device for driving the rotary platform to rotate.

[0008] An auxiliary support structure for a rotary platform of a three-dimensional parking garage includes a support base mounted on a lifting arm, an auxiliary support rod mounted at one end on the rotary platform, and a roller assembly mounted at the other end of the auxiliary support rod; the roller assembly rolls on the support base.

[0009] Furthermore, there are no fewer than four auxiliary support rods, which are evenly distributed along the circumference of the rotating platform.

[0010] Furthermore, the support base is annular and concentric with the central cylinder.

[0011] Furthermore, radial reinforcing ribs are provided between the support base and the central cylinder.

[0012] Furthermore, the roller assembly includes an opening slot provided on the auxiliary support rod, a central shaft fixedly connected to the side wall of the opening slot, and a roller rotatably connected to the central shaft.

[0013] Furthermore, the roller is equipped with a bearing, and the central shaft is interference-fitted with the inner ring of the bearing.

[0014] Furthermore, the central shaft is provided with a retaining ring to prevent the bearing from moving, one end of the central shaft is provided with a flange, and the other end of the central shaft is fixed to the side wall of the auxiliary support rod with a nut.

[0015] The beneficial effects of this application are:

[0016] This application uses an auxiliary support set between the slewing platform and the support arm to support the edge of the slewing platform on the support arm, which increases the rigidity of the slewing platform and can prevent deformation of the edge of the slewing platform.

[0017] By using rollers, the friction between the support arm and the auxiliary support rod changes from sliding friction to rolling friction, reducing wear and extending service life. Attached Figure Description

[0026] 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.

[0027] Example 1

[0028] like Figure 1 As shown in Figure 4,

[0029] like Figure 4 As shown, the underground parking garage rotary platform includes three lifting arms 3 evenly distributed along the circumference of the central cylinder 31, a rotary platform 1 rotatably connected to the central cylinder 31, and a drive device 2 for driving the rotary platform 1 to rotate; the rotary platform 1 and the central cylinder 31 are rotated through a rotary bearing.

[0030] An auxiliary support structure for a rotating platform of a three-dimensional parking garage includes a support base 7 mounted on a lifting arm 3, an auxiliary support rod 4 with one end mounted on a rotating platform 1, and a roller assembly 5 mounted on the other end of the auxiliary support rod 4; the roller assembly 5 rolls on the support base 7.

[0031] Since the edge of the rotary platform 1 is suspended, the auxiliary support rod 4 is fixed to the edge of the rotary platform 1 to enhance the rigidity of the rotary platform 1.

[0032] Generally, the radius of the rotary platform 1 is not less than 3.5-4 meters. In order to ensure the strength of the edge parts, the more auxiliary support rods 4, the better. However, the more rods there are, the heavier the entire rotary platform will be, and the greater the lifting force required. This is uneconomical. Therefore, the number of auxiliary support rods 4 is set to four, and the four auxiliary support rods 4 are evenly distributed along the circumference of the rotary platform 1.

[0033] like Figure 3 As shown, the support base 7 is annular and concentric with the central cylinder 31. The support base 7 and the auxiliary support rod 7 are located on the same circle to prevent the roller 52 of the auxiliary support rod 4 from detaching from the support base 7.

[0034] like Figure 2 As shown, the roller assembly 5 includes an opening slot 51 provided on the auxiliary support rod 4, a central shaft 54 ​​fixedly connected to the side wall of the opening slot 51, and a roller 52 rotatably connected to the central shaft 54.

[0035] The roller 52 is provided with a bearing 53, and the central shaft 54 ​​is tightly fitted with the inner ring of the bearing 53.

[0036] The central shaft 54 ​​is provided with snap rings 56 to prevent the bearing 53 from moving. There are two snap rings 56, which are respectively located at both ends of the inner ring of the bearing 53.

[0037] One end of the central shaft 54 ​​is provided with a flange, and the other end of the central shaft 54 ​​is fixed to the side wall (auxiliary support rod 4) of the opening groove 51 with a nut 55. Tightening the nut 55, the central shaft 54 ​​is fixed to the auxiliary support rod 4 by the flange and the nut 55.

[0038] The working process of this application,

[0039] When a vehicle needs to be parked, the rotary platform 1 is lifted to the ground by a chain on the lifting arm 3. The car is driven onto the rotary platform 1, and then, depending on the parking space availability in the garage, the rotary platform 1 descends to the garage level with an available space. As the rotary platform 1 rotates around the central cylinder 31, the rollers 52 roll on the support base 7. After aligning the car with the parking space, a track robot stores the car in the parking space. Because the rotary platform 1 is equipped with auxiliary support rods 4 and rollers 52 supporting it on the lifting arm 3, sagging and deformation of the edge of the rotary platform 1 can be avoided.

[0040] Example 2

[0041] This embodiment has a basically the same structure as Embodiment 1.

[0042] The difference is that,

[0043] like Figure 3 As shown,

[0044] Because the support base 7 is relatively far from the adjacent lifting arms 3, there are two solutions to ensure sufficient strength: one is to increase the thickness of the support base 7, and the other is to set up a reinforcing structure. To save costs and reduce the overall weight, the reinforcing structure solution is adopted.

[0045] The support base 7 and the central cylinder 31 are provided with radial reinforcing ribs 8.

[0046] The strength of the support base 7 is increased by the reinforcing ribs 8, which prevents the support base 7 from deforming.

[0047] Example 3

[0048] This embodiment has a basically the same structure as Embodiment 1.

[0049] The difference is that,

[0050] like Figure 1 As shown,

[0051] The auxiliary support rod 4 is connected to the rotary platform 1 at one end with a flange 6 welded on it. The flange 6 is fixedly connected to the rotary platform 1 by bolts and nuts.

[0052] By setting flange 6, the contact area between auxiliary support rod 4 and rotary platform 1 is increased, thereby increasing the stability of auxiliary support rod 4.

[0053] The above description is merely a preferred embodiment of this application; however, the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
