Description

Technical Field

[0001] This application relates to the field of AGV forklifts, and more particularly to an AGV forklift attachment lifting mechanism. Background Technology

[0002] AGV forklifts, or Automated Guided Vehicles, are highly automated material handling equipment. Through built-in navigation systems and sensor technology, they can autonomously complete tasks such as handling and loading / unloading goods according to preset paths or real-time instructions without human intervention. AGV forklifts combine the load-bearing capacity of forklifts with automatic navigation technology, eliminating the need for manual driving and enabling autonomous navigation and obstacle avoidance in complex warehouse environments. Forklift attachment lifting mechanisms are auxiliary equipment installed on forklifts to raise and lower various attachments, such as grabs, hooks, and pushers, to adapt to different operational needs. These attachments are connected to the forklift's main hydraulic system through the lifting mechanism, achieving the lifting function through components such as hydraulic cylinders, chains, and pulley blocks. In conventional lifting mechanisms, one end of the fixed frame is connected to one end of the forklift. An adjusting frame is slidably connected to the surface of the fixed frame. The material shovel at one end of the adjusting frame scoops up materials, and the adjusting frame controls the raising and lowering of the material shovel, facilitating the transport of materials to a suitable location.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional material shovels, due to their limited size, are prone to tipping over when handling larger materials, especially when the forklift is moving. Conventional automated guided vehicles (AGVs) adjust according to the material's condition, thus affecting the ease of use of AGVs.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of material tipping during transport by conventional AGV forklifts, this application provides an AGV forklift attachment lifting mechanism.

[0006] The AGV forklift attachment lifting mechanism provided in this application adopts the following technical solution:

[0007] An AGV forklift attachment lifting mechanism includes a fixed frame and two adjusting blocks. The adjusting frame is slidably mounted on the surface of the fixed frame. A material shovel plate is fixedly connected to one end of the adjusting frame. A telescopic rod is rotatably mounted on one end of the adjusting block. A limit frame is fixedly connected to the end of the telescopic rod away from the adjusting block, and a rotating frame is fixedly mounted on the surface of the telescopic rod. An electric push rod is rotatably connected to one end of the rotating frame. A mounting frame is rotatably mounted on one end of the electric push rod. One end of the adjusting block is slidably connected to the surface of the adjusting frame. The limit frame has a "V" shaped cross-section. One end of the mounting frame is welded to the surface of the adjusting frame.

[0009] Preferably, a control motor is fixedly installed on the top of the slide rail, and a threaded rod is fixedly connected to the output end of the control motor. The surface of the threaded rod is threaded onto the inner wall of the adjusting block, and the center of the threaded rod is on the same straight line as the center of the control motor.

[0010] Preferably, the bottom end of the threaded rod is rotatably connected to a bearing, the bottom end of the bearing is fixedly installed to the inner wall of the slide rail, and the center of the bearing and the center of the threaded rod are on the same straight line.

[0011] Preferably, one end of the limiting frame is fixedly connected to an anti-slip plate, the size and specifications of the surface of the anti-slip plate are adapted to the size and specifications of the surface of the limiting frame, and the anti-slip plate is a rubber sheet.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing an adjusting block on the surface of the adjusting frame, a limit frame is installed on the inner wall of the adjusting block via a telescopic rod. An electric push rod is installed on the surface of the limit frame via a rotating frame. One end of the electric push rod is connected to the surface of the adjusting block via a mounting frame, so that the limit frame at one end of the rotating frame can be rotated after the electric push rod adjusts its own length, thereby limiting the material on the surface of the material shovel. A slide rail is slidably installed on the inner wall of the adjusting block, so that the limit frame can be easily fixed to materials of different heights. A control motor is installed on the top of the slide rail, and a threaded rod is installed on the output end of the control motor, so that the threaded rod can be rotated after the control motor is started, thereby controlling the adjustment block to move on the slide rail. A bearing is installed at the bottom end of the threaded rod, so that the threaded rod can be rotated with the help of the bearing. Compared with the existing technology, this method effectively improves the stability of the AGV forklift in handling objects.

[0016] 2. A rubber anti-slip plate can also be installed at one end of the limit frame to increase the friction between the limit frame and the material. A rotating block is rotatably connected to the inner wall of the limit frame, and a return spring is installed between the rotating block and the limit frame. A pressure sensor is installed on the inner wall of the limit frame to detect the pressure on the rotating block and facilitate adjustment of the fixing force of the limit frame.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses an AGV forklift attachment lifting mechanism, referring to... Figure 1 - Figure 2 The system includes a fixed frame 1. In use, one end of the fixed frame 1 is connected to one end of the forklift. An adjustable frame 2 is slidably connected to the surface of the fixed frame 1. A material shovel 3 at one end of the adjustable frame 2 scoops up materials. The material shovel 3 is raised and lowered by the adjustable frame 2 to facilitate the transport of materials to a suitable position. An adjustable block 4 is installed on the surface of the adjustable frame 2. A limit frame 6 is installed on the inner wall of the adjustable block 4 via a telescopic rod 5. An electric push rod 8 is installed on the surface of the limit frame 6 via a rotating frame 7. One end of the electric push rod 8 is connected to the surface of the adjustable block 4 via a mounting frame 9. After adjusting its own length, the electric push rod 8 controls the rotation of the limit frame 6 at one end of the rotating frame 7, so that the limit frame 6 limits the materials on the surface of the material shovel 3, effectively improving the stability of the AGV forklift in transporting objects and preventing materials from tilting or falling during transport.

[0024] Reference Figure 2 A slide rail 10 is slidably installed on the inner wall of the adjusting block 4. One end of the slide rail 10 is connected to the surface of the adjusting frame 2. The height of the adjusting block 4 can be easily adjusted by the slide rail 10, thereby controlling the movement of the limiting frame 6 and fixing materials of different heights. A control motor 11 is installed on the top of the slide rail 10. A threaded rod 12 is installed on the output end of the control motor 11. The surface of the threaded rod 12 is threadedly connected to the inner wall of the adjusting block 4. After the control motor 11 is started, it controls the rotation of the threaded rod 12, thereby controlling the adjustment block 4 to move on the slide rail 10, which is more convenient to use. A bearing 13 is installed at the bottom end of the threaded rod 12. The bottom end of the bearing 13 is connected to the inner wall of the slide rail 10, which facilitates the rotation of the threaded rod 12.

[0025] Reference Figure 3 - Figure 4 A rubber anti-slip plate 14 is installed at one end of the limiting frame 6. The anti-slip plate 14 increases the friction between the limiting frame 6 and the material, and avoids damage to the surface of the material. A rotating block 15 is rotatably connected to the inner wall of the limiting frame 6. A return spring 17 is installed between the rotating block 15 and the limiting frame 6. The return spring 17 causes the rotating block 15 to return to its original position after being subjected to pressure. A pressure sensor 16 is installed on the inner wall of the limiting frame 6. The pressure sensor 16 detects the pressure on the rotating block 15 when the material is squeezed, thereby detecting the clamping force of the limiting frame 6 on the material, which facilitates the adjustment of the fixing force of the limiting frame 6. A fixing bolt 18 is installed on the threaded surface of the telescopic rod 5. The length of the limiting frame 6 is adjusted by the telescopic rod 5, which is convenient for fixing materials of different sizes. The length of the telescopic rod 5 is fixed by the fixing bolt 18.

[0026] The implementation principle of an AGV forklift attachment lifting mechanism according to an embodiment of this application is as follows: An adjusting block 4 is installed on the surface of the adjusting frame 2. A limit frame 6 is installed on the inner wall of the adjusting block 4 via a telescopic rod 5. An electric push rod 8 is installed on the surface of the limit frame 6 via a rotating frame 7. One end of the electric push rod 8 is connected to the surface of the adjusting block 4 via a mounting frame 9, so that the limit frame 6 at one end of the rotating frame 7 can be rotated after the electric push rod 8 adjusts its own length. This limits the material on the surface of the material shovel plate 3, preventing the material from tilting or falling during forklift handling. A slide rail 10 is slidably installed on the inner wall of the adjusting block 4. One end of the slide rail 10 is connected to the adjusting block 4 via a telescopic rod 5. The frame 2 is connected to the surface to facilitate the adjustment of the height of the adjusting block 4 with the help of the slide rail 10, thereby controlling the movement of the limit frame 6 and fixing materials of different heights. A control motor 11 is installed on the top of the slide rail 10, and a threaded rod 12 is installed on the output end of the control motor 11. The surface of the threaded rod 12 is threadedly connected to the inner wall of the adjusting block 4, so that the control motor 11 can control the rotation of the threaded rod 12 after starting, and control the movement of the adjusting block 4 on the slide rail 10, which is more convenient in use. A bearing 13 is installed at the bottom end of the threaded rod 12, and the bottom end of the bearing 13 is connected to the inner wall of the slide rail 10, so that the threaded rod 12 can be rotated with the help of the bearing 13.

[0027] A rubber anti-slip plate 14 can be installed at one end of the limiting frame 6 to increase the friction between the limiting frame 6 and the material, and to prevent the limiting frame 6 from damaging the material surface. A rotating block 15 is rotatably connected to the inner wall of the limiting frame 6. A return spring 17 is installed between the rotating block 15 and the limiting frame 6. The return spring 17 causes the rotating block 15 to recover automatically after being subjected to pressure. A pressure sensor 16 is installed on the inner wall of the limiting frame 6 so that the rotating block 15 can be squeezed by the material. The pressure sensor 16 detects the pressure on the rotating block 15, thereby detecting the clamping force of the limiting frame 6 on the material, which facilitates the adjustment of the fixing force of the limiting frame 6. A fixing bolt 18 is installed on the threaded surface of the telescopic rod 5 so that the length of the limiting frame 6 can be adjusted by the telescopic rod 5, which is convenient for fixing materials of different sizes. The length of the telescopic rod 5 is fixed by the fixing bolt 18.
