Description

Technical Field

[0001] This utility model relates to the field of AGV technology for handling and stacking, specifically a wide-legged narrow-channel AGV. Background Technology

[0002] In the ever-evolving manufacturing sector, automation and intelligence have become key drivers for improving production efficiency and reducing labor costs. Among them, automated guided vehicles (AGVs), as an important component of intelligent manufacturing, can effectively solve the efficiency, safety, and cost problems of manual forklifts by leveraging their advanced technologies such as autonomous navigation, intelligent obstacle avoidance, and precise positioning, thus becoming an important force in promoting the upgrading of manufacturing logistics.

[0003] Currently, the wheels of existing AGVs are located behind the forks. In order to maintain the stability of the forks when handling and stacking goods and to prevent them from tipping over, it is often necessary to place other components besides the forks and the mast lifting system behind the forks and to install counterweights. This increases the overall length of the vehicle. When such AGVs work in workshops and warehouses with limited space, the flexibility and convenience of turning are affected to some extent because the passageways available for the AGVs to pass through are relatively narrow.

[0004] In addition, in order to increase the overall strength, it is often necessary to weld the outer mast assembly of the gantry lifting system to the vehicle frame, which not only makes the installation of the gantry lifting system inconvenient, but also makes the disassembly and maintenance of the gantry lifting system difficult. Utility Model Content

[0005] The purpose of this invention is to overcome the defects and shortcomings of the existing technology and provide a wide-leg narrow-channel AGV to facilitate the installation, disassembly and maintenance of the outer gantry of the gantry lifting system, and to improve flexibility and stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wide-legged narrow-aisle AGV includes a frame, a mast lifting system, forks, an electrical control module, a battery, and a servo motor. The frame is a single, integral load-bearing frame consisting of two forks, a load-bearing base plate, left and right side panels, a rear panel, and a mast fixing plate. The outer mast assembly of the mast lifting system is mounted on the mast fixing plate. The electrical control module, battery, and servo motor are respectively mounted on the rear sides of the left and right side panels. The two forks are located on opposite sides of the forks.

[0008] Furthermore, a support base is fixedly connected between the rear sides of the top of the left and right side plates, and the electrical control module is mounted on the support base.

[0009] Furthermore, a battery mounting plate is fixedly connected between the rear sides of the middle portion of the left and right side plates, and the battery is mounted on the rear side of the battery mounting plate.

[0011] Furthermore, left and right balance wheels are respectively installed on the bottom of the base plate on both sides of the servo motor, and load-bearing wheels are respectively installed on the front side of the two forks. The drive end of the servo motor is connected to a traveling wheel, and the traveling wheel, the left and right balance wheels, and the load-bearing wheel travel together on the ground.

[0012] Furthermore, a servo mounting plate is fixedly connected between the bottom of the left and right upright plates, and the servo is mounted on the servo mounting plate.

[0013] Furthermore, the left and right side plates are respectively fixedly connected to the two fork legs with hoisting reinforcing ribs.

[0014] Furthermore, lifting rings are fixedly connected to the top of the left and right side plates and the two forks, respectively.

The outer mast assembly of the mast lifting system 2 is mounted on the mast fixing plate 1-5. The electrical control module 4, battery 5, and servo motor 6 are respectively mounted on the rear side of the left and right side plates 13. The two forks 11 are respectively located on both sides of the forks 3.

[0026] In this utility model, a support base 7 is fixedly connected between the rear side of the top of the left and right side plates 1-3, and the electrical control module 4 is installed on the support base 7, thereby realizing the rear placement of the electrical control module 4.

[0027] In this utility model, a battery mounting plate 8 is fixedly connected between the rear sides of the middle part of the left and right side plates 1-3, and the battery 5 is installed on the rear side of the battery mounting plate 8, thereby realizing the rear placement of the battery 5.

[0028] In this utility model, a base plate 9 is fixedly connected to the inner side of the bottom of the rear panel 1-4, and left and right upright plates 10 are fixedly connected to the base plate 9 respectively, so as to support the battery 5.

[0029] In this utility model, the bottom of the base plate 9 is equipped with left and right balance wheels 16 on both sides of the servo motor, and the front of the two forks 1-1 is equipped with load-bearing wheels 11. The drive end of the servo motor 6 is connected to the traveling wheel 12, and the traveling wheel 12, the left and right balance wheels 16 and the load-bearing wheel 11 travel together on the ground.

[0030] It should be noted that the walking wheel 12 can be driven by a drive motor coaxially connected to it, and the servo motor 6 drives the walking wheel 12 to achieve steering.
