Description

Technical Field

[0001] This utility model relates to the field of AGV parking machine technology, specifically a parking platform for an AGV automatic parking robot. Background Technology

[0002] With the improvement of people's living standards, cars have become a necessity for almost every household. Now, there is often a shortage of parking spaces. In order to solve this problem, some places have built multi-level parking garages. Compared with traditional flat parking lots, multi-level parking garages can make full use of vertical space. Car owners can park their vehicles on designated parking platforms, and unmanned guided vehicles will move the parking platforms and vehicles to designated locations. Unmanned guided vehicles (AGVs) refer to transport vehicles equipped with electromagnetic or optical automatic guidance devices, which can travel along a prescribed guidance path and have safety protection and various transfer functions.

[0003] Parking lot surfaces can become uneven due to long-term exposure to vehicle pressure, geological subsidence, or construction quality issues. This can cause the parking platform to tilt during AGV parking machine transport, potentially causing vehicles to fall off the platform.

[0004] To address the aforementioned issues, an AGV (Automated Guided Vehicle) parking robot is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an AGV automatic parking robot that solves the problem of cars falling off the parking platform due to uneven road surfaces in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an AGV automatic parking robot, comprising: an AGV parking machine, wherein lifting columns are installed at the four corners of the AGV parking machine; and a parking platform, wherein the parking platform includes a base, a parking plate, and hydraulic cylinders, the base being placed above the lifting columns, and two sets of support rods and two sets of hydraulic cylinders being fixedly connected above the base, the parking plate being rotatably connected between the two sets of support rods, and the output shafts of the two sets of hydraulic cylinders being connected to the underside of the parking plate through a guide mechanism.

[0007] As a further description of the above technical solution: the guiding mechanism includes a slider and a guide groove. The guide groove is vertically opened inside the parking plate, and the slider is slidably connected in the guide groove. The output shaft of the hydraulic cylinder is rotatably connected to the slider.

[0008] As a further description of the above technical solution: a level sensor is installed below the parking plate.

[0009] As a further description of the above technical solution: a ramp is fixedly connected to the end of the parking plate away from the limit plate, and a ramp is provided at the end of the ramp away from the parking plate. The ramp is installed on the ground, and the ramp and the ramp have the same tilt angle.

[0010] As a further description of the above technical solution: support columns are fixedly connected to the four corners of the base.

[0011] As a further description of the above technical solution: the height of the support column is higher than that of the AGV parking machine.

[0012] As a further description of the above technical solution: a limit plate is fixedly connected to one end of the parking plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the AGV parking machine encounters uneven ground during transportation, the parking platform provided by this utility model uses the hydraulic cylinder output shaft to rotate the parking plate through the guide mechanism, so that the parking plate is restored to a horizontal state with the ground, thus preventing the vehicle from falling off the platform when the robot passes over uneven road surfaces.

[0015] 2. The parking plate provided by this utility model is fixedly connected to one end of the parking plate, so that the driver does not let the vehicle go beyond the parking plate when parking. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figure 1 and Figure 2 An AGV automatic parking robot includes: an AGV parking machine 1, with lifting columns 2 installed at each of the four corners of the AGV parking machine 1; and a parking platform, which includes a base 3, a parking plate 4, and hydraulic rods 7. The base 3 is placed above the lifting columns 2, and the lifting columns 2 can support the entire parking platform when raised. Two sets of support rods 5 and two sets of hydraulic rods 7 are fixedly connected to the top of the base 3. The parking plate 4 is rotatably connected between the two sets of support rods 5, and the output shafts of the two sets of hydraulic rods 7 are connected to the bottom of the parking plate 4 through a guide mechanism.

[0024] Combination Figure 3 and Figure 4 The guiding mechanism includes a slider 6 and a guide groove 13. The parking plate 4 has a vertically opened guide groove 13, and the slider 6 is slidably connected in the guide groove 13. The output shaft of the hydraulic lever 7 is rotatably connected to the slider 6. When the output shaft of the hydraulic lever 7 extends or retracts, it rotates along the slider 6, and the slider 6 slides in the guide groove 13. A horizontal sensor 12 is installed under the parking plate 4, which can detect the tilt angle of the parking plate 4 and convert it into the extension and retraction length of the output shaft of the hydraulic lever 7. A ramp 9 is set at the end of the ramp 8 away from the parking plate 4. The ramp 9 is installed on the ground and the tilt angle of the ramp 9 is the same as that of the ramp 8, which makes it convenient for the driver to drive the car onto the parking plate 4. Support columns 11 are fixedly connected to the four corners of the base 3 to support the entire parking platform. The support columns 11 are higher than the AGV parking machine 1, allowing the AGV parking machine 1 to drive under the parking platform base 3. A limit plate 10 is fixedly connected to one end of the parking plate 4 to restrict the position of the vehicle and prevent the vehicle from parking off the parking plate 4.

[0025] Working principle: When the driver drives the vehicle up the ramp 9, there is a ramp 8 on the parking platform 4 with the same tilt angle as the ramp 9. The driver can continue to drive the vehicle onto the parking platform 4. A limit plate 10 is fixedly connected to the end of the parking platform 4 away from the ramp 8. When the front wheels of the vehicle reach the limit plate 10, they cannot continue to move forward, prompting the driver to stop. After the driver gets off the vehicle, the AGV parking machine 1 moves to the base 3 below the parking platform. The lifting column 2 of the AGV parking machine 1 rises to support the entire parking platform. When the AGV parking machine 1 moves and encounters uneven ground, the horizontal sensor 12 installed under the parking platform 4 detects the tilt angle of the platform. The horizontal sensor 12 converts the detected tilt angle into an electrical signal for the extension length required by the output shaft of the hydraulic lever 7. When the output shaft of the hydraulic lever 7 extends and retracts, the parking platform 4 will rotate between the support rods 5 until it is horizontal due to the guide mechanism.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
