Description

Technical Field

[0001] This application relates to the field of parking equipment technology, and in particular to a lifting platform device for mechanical parking garages. Background Technology

[0002] Mechanical automated parking systems, with their advantages of fully utilizing vertical space and improving land utilization, play an important role in solving the parking difficulties of modern cities, satisfying people's need for more parking spaces within limited areas. However, traditional mechanical automated parking systems still have shortcomings in their lifting platforms: they lack stable positioning devices, and changes in the load on the platform cause slight undulations in the platform track, resulting in a significant height difference between the platform track and the structural track. Utility Model Content

[0003] To address the aforementioned problems, improve the positioning stability of the lifting platform, and reduce the height variation of the platform track, this application provides a lifting platform device for mechanical parking garages.

[0004] The lifting platform device for mechanical parking garages provided in this application adopts the following technical solution.

[0005] A lifting platform device for a mechanical parking garage includes:

[0006] The lifting platform body includes a lifting platform base frame, on which a lifting guide device is provided for guiding the lifting of the lifting platform body, and trolley tracks are provided on both sides of the lifting platform base frame;

[0007] The lifting and leveling device includes two first pin seats spaced apart on the lifting platform base frame. A first power unit is installed on the lifting platform base frame between the two first pin seats. The first power unit drives the hinge plate to rotate. The close ends of the two connecting rods are distributed at a 180-degree angle and hinged to the hinge plate. The far ends of the two connecting rods are respectively hinged to the first pins that cooperate with the first pin holes of the two first pin seats.

[0008] The track leveling device includes a second pin seat located at one end of the trolley track. A second pin is axially movable and circumferentially fixed inside the second pin seat. A second nut is provided on the second pin. A second power unit is provided on the trolley track. The second power unit drives a screw that is threadedly engaged with the second nut to rotate.

[0009] By adopting the above technical solutions, the lifting guide device guides the lifting platform body as it moves along the lifting frame, ensuring stable vertical sliding without derailment. The lifting leveling device, driven by the first power unit to rotate the hinged plate, extends or retracts the first pin via a connecting rod, acting as a fall arrestor for the lifting platform body. After the lifting platform body reaches the designated position, the first pin extends and locks, preventing a fall. The track leveling device, powered by the second power unit, extends or retracts the second pin via a threaded connection. After the lifting platform body reaches the designated position, the second pin extends and engages with the structural track to lock and position the trolley track, ensuring that the trolley track does not fluctuate in height due to load changes, reducing height differences, and ensuring stability between the trolley track and the structural track.

[0010] Optionally, the lifting guide device includes a lifting guide seat and two guide wheel groups. The lifting guide seat is mounted on the lifting platform base frame. The guide wheel group includes a guide wheel seat mounted on the lifting guide seat and a guide wheel mounted on the guide wheel seat. The guide wheels of the two guide wheel groups are distributed at a horizontal angle of 90 degrees.

[0011] The lifting guide device is provided in four parts, and is symmetrically distributed in two groups on the base frame of the lifting platform. The two lifting guide devices in the same group are distributed vertically at intervals and are distributed at a horizontal angle of 90 degrees.

[0012] By adopting the above technical solution and setting up four lifting guide devices, the guide wheels of two symmetrically distributed lifting guide devices can grip the lifting frame from both sides, and the guide wheels of two lifting guide devices in the same group can grip the lifting frame from the other two sides, ensuring the stable cooperation between the main body of the lifting platform and the lifting frame and preventing derailment.

[0013] Optionally, the lifting guide device further includes a guide wheel assembly adjustment component. The guide wheel assembly adjustment component includes a lifting guide seat with an elongated hole. Two guide wheels are arranged vertically at intervals. The guide wheel seat is slidably disposed in the elongated hole through a guide wheel seat shaft, so that the two guide wheel sets move closer to or further away from each other. An adjustment rod is arranged radially on the guide wheel seat shaft. The adjustment rod passes through an adjustment plate on the lifting guide seat, and a first nut is threaded onto the adjustment rod on both sides of the adjustment plate.

[0014] By adopting the above technical solution, the position of the adjusting rod can be adjusted by adjusting the position of the two first nuts on the adjusting rod, and then the position of the guide wheel seat shaft in the elongated hole can be adjusted, so that the position of the guide wheel assembly on the lifting guide seat changes, thereby changing the positional distance between the two guide wheel assemblies.

[0015] Optionally, the lifting guide device further includes a right-angle bent plate, with connecting slots at both ends of the right-angle bent plate, which are respectively connected to two guide wheel seats by bolts.

[0016] By adopting the above technical solution and setting the right-angle bend plate, the two guide wheel groups can be connected together, which improves their stability. Furthermore, the opening of the connecting slot will not interfere with the adjustment of the position of the two guide wheel groups.

[0017] Optionally, the main body of the lifting platform also includes two lifting platform columns spaced apart on one side of the lifting platform base frame, and of the two lifting guide devices in the same group, the upper lifting guide device is installed on the lifting platform column.

[0018] By adopting the above technical solution and setting the lifting platform columns, the height difference between the two lifting guide devices in the same group can be increased. By increasing the lever arm, the force is reduced, and the lifting stability of the main body of the lifting platform is improved.

[0019] Optionally, the lifting and leveling device is located between the two lifting platform columns.

[0020] Optionally, a limit block is provided at the other end of the trolley track.

[0021] Optionally, a lifting platform hanger is provided on one side of the lifting platform base frame.

[0022] Optionally, the lifting platform base frame is provided with platform guardrails.

[0023] By adopting the above technical solutions, platform guardrails can serve as protective devices for personnel during maintenance, thereby improving operational safety.

[0024] Optionally, the lifting platform base is provided with a fall protection step platform, which includes a mesh plate installed on the lifting platform base.

[0025] By adopting the above technical solution, the fall arrestor platform can be used as a work surface for personnel maintenance.

[0026] In summary, this application includes at least the following beneficial effects:

[0027] 1. This application utilizes a lifting guide device to guide the lifting platform body as it moves along the lifting frame, ensuring stable vertical sliding without derailment. The lifting leveling device, driven by the first power unit to rotate the hinged plate, extends or retracts the first pin via a connecting rod, acting as a fall prevention measure for the lifting platform body. After the lifting platform body reaches the designated position, the first pin extends and locks, preventing a fall. The track leveling device, powered by a second power unit, extends or retracts the second pin via a threaded connection. After the lifting platform body reaches the designated position, the second pin extends and engages with the structural track to lock and position the trolley track, ensuring that the trolley track does not fluctuate in height due to load changes. This maintains or reduces the height difference between the platform track and the structural track, ensuring stability between the trolley track and the structural track.

[0028] 2. This application uses four lifting guide devices. Two symmetrically distributed lifting guide devices have guide wheels that can grip the lifting frame from both sides. Two lifting guide devices in the same group have guide wheels that can grip the lifting frame from the other two sides, ensuring stable cooperation between the lifting platform body and the lifting frame and preventing derailment.

[0029] 3. This application adjusts the position of the adjusting rod by adjusting the position of the two first nuts on the adjusting rod, which in turn adjusts the position of the guide wheel seat shaft in the elongated hole, causing the guide wheel assembly to change position on the lifting guide seat, thereby changing the positional distance between the two guide wheel assemblies. This allows for the clamping of rails of different specifications and is applicable to lifting frame of different sizes, thus improving applicability. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] The following is in conjunction with the appendix Figures 1 to 10 This application will be described in further detail.

[0044] This application discloses a lifting platform device for mechanical parking garages.

[0045] Reference Figures 1 to 10 A lifting platform device for mechanical parking garages includes: a lifting platform body, a lifting guide device, a lifting leveling device, and a track leveling device.

[0046] The main body of the lifting platform includes a lifting platform base frame 1 and two lifting platform columns 2 arranged at intervals on one side (rear side) of the lifting platform base frame 1. Trolley tracks 3 are arranged on both sides of the lifting platform base frame 1.

[0047] A lifting guide device is installed on the main body of the lifting platform and is used to guide the lifting of the main body of the lifting platform.

[0048] Four lifting guide devices are provided, symmetrically distributed in two groups on the main body of the lifting platform. The two lifting guide devices in each group are spaced vertically apart, forming a 90-degree horizontal angle. Within the same group, the lower lifting guide device is mounted on the lifting platform base frame 1, and the upper lifting guide device is mounted on the lifting platform column 2. By using four lifting guide devices and the lifting platform column 2, the height difference between the two lifting guide devices in the same group can be increased. This increases the lever arm, reduces the stress, and improves the lifting stability of the main body of the lifting platform.

[0049] The lifting guide device includes a lifting guide seat 4, two guide wheel groups, and a guide wheel group adjustment assembly. The lifting guide seat 4 is mounted on the main body of the lifting platform. The lifting guide seat 4 consists of a lifting guide seat base plate, a first right-angle plate, and a second right-angle plate. The lifting guide seat base plate is mounted on the main body of the lifting platform. The first right-angle plate and the second right-angle plate are fixed to the lifting guide seat base plate and are arranged at right angles. The guide wheel group includes a guide wheel seat 5 and a guide wheel 6. The guide wheel seat 5 is mounted on the lifting guide seat 4. The guide wheel 6 is rotatably mounted on the guide wheel seat 5. There are two guide wheels 6 spaced vertically. The guide wheels 6 of the two guide wheel groups are distributed at a horizontal angle of 90 degrees.

[0050] The guide wheel assembly adjustment component includes a lifting guide seat 4 with an elongated hole on a first right-angle plate and a second right-angle plate. A guide wheel seat 5 is slidably mounted within the elongated hole via a guide wheel seat shaft 7, allowing the two guide wheel assemblies to move closer or further apart. An adjusting rod 8 is radially mounted on the guide wheel seat shaft 7, passing through an adjusting plate 9 on the lifting guide seat 4. Each adjusting rod 8 on both sides of the adjusting plate 9 has a first nut 10 threadedly fitted onto it. By adjusting the position of the two first nuts 10 on the adjusting rod 8, the position of the adjusting rod 8 can be adjusted, thereby adjusting the position of the guide wheel seat shaft 7 within the elongated hole. This causes a change in the position of the guide wheel assemblies on the lifting guide seat 4, thus altering the positional distance between the two guide wheel assemblies. This allows for the clamping of rails of different specifications and is suitable for lifting frame structures of different sizes, improving applicability.

[0051] With the installation of four lifting guide devices, the guide wheels 6 of two symmetrically distributed lifting guide devices can grip the lifting frame from both sides, and the guide wheels 6 of two lifting guide devices in the same group can grip the lifting frame from the other two sides, ensuring the stable cooperation between the main body of the lifting platform and the lifting frame, and making it less prone to derailment.

[0052] The lifting guide device also includes a right-angle bent plate 11, with connecting slots at both ends of the right-angle bent plate 11. These connecting slots are bolted to the two guide wheel seats 5, respectively. The right-angle bent plate 11 allows the two guide wheel groups to be connected together, improving their stability. Furthermore, the connecting slots prevent interference with the adjustment of the positions of the two guide wheel groups.

[0053] The lifting and leveling device is located between two lifting platform columns 2. It includes two first pin seats 12 spaced apart on the lifting platform base frame 1. A first power unit 13 is installed on the lifting platform base frame 1 between the two first pin seats 12. The first power unit 13 can be a motor reducer unit. The first power unit 13 drives the hinge plate 14 to rotate. The close ends of the two connecting rods 15 are distributed at an angle of 180 degrees and are hinged to the hinge plate 14. The far ends of the two connecting rods 15 are respectively hinged to the first pins 16 that cooperate with the holes of the two first pin seats 12. The head end of the first pin 16 is tapered.

[0054] The track leveling device includes a second pin seat 17 located at one end of the trolley track 3. A second pin 18 is axially movable and circumferentially fixed inside the second pin seat 17. The first end of the second pin 18 is tapered, and a second nut 19 is provided on the second pin 18. A second power unit 20 is provided on the trolley track 3. The second power unit 20 can be a motor reducer unit. The second power unit 20 drives the screw 21, which is threadedly engaged with the second nut 19, to rotate through a sprocket and chain transmission.

[0055] A limit block 22 is provided at the other end of the trolley track 3. The trolley track is part of the platform device. Other mechanisms on the lifting platform base frame need to use the trolley track to run. As track support, the limit block 22 can play a limiting role.

[0056] A lifting platform hanger 23 is provided on one side of the lifting platform base frame 1, which is the lifting point of the lifting platform device.

[0057] The platform base frame 1 is equipped with a platform guardrail 24, which can serve as a protective device for personnel during maintenance, thereby improving operational safety.

[0058] The lifting platform base frame 1 is equipped with a fall protection platform 25. The fall protection platform 25 includes a mesh plate, which can be a metal mesh, installed on the lifting platform base frame 1. The fall protection platform 25 can be used as a work surface for personnel maintenance.

[0059] This application utilizes a lifting guide device to guide the lifting platform body as it moves along the lifting frame, ensuring stable vertical sliding without derailment. A lifting leveling device, driven by the first power unit 13 to rotate the hinge plate 14, extends or retracts the first pin 16 via the connecting rod 15, acting as a fall arrestor for the lifting platform body. After the lifting platform body reaches the designated position, the first pin 16 extends and locks, preventing a fall. A track leveling device, powered by the second power unit 20, extends or retracts the second pin 18 via a threaded connection. After the lifting platform body reaches the designated position, the second pin 18 extends and engages with the structural track to lock and position the trolley track 3, preventing height fluctuations due to load changes, reducing height differences, and ensuring stability between the trolley track frame and the structural track. Compared to traditional mechanical automated parking systems, this application has lower requirements for the depth of the lift pit because the dimension from the top surface of the lift platform 1 to the bottom is very small, so a deep depth is not required. This places high demands on construction costs and difficulty.
