[0015] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0016] Figure 1 to Figure 2 Shown is a schematic structural diagram of the utility model.

[0017] The figures are marked as follows: mast base plate 1, forklift mast 2, mounting block 3, mounting shaft 4, roller 5, roller mounting seat 6, transmission shaft 7, forklift connecting plate 8, steering gear box 9, stepper motor 10, coupling 11, synchronous wheel 12, first synchronous connecting plate 13, second synchronous connecting plate 14, first driven wheel 15, first driven wheel 16, synchronous belt 17.

[0018] like Figure 1 and Figure 2 As shown, the AGV forklift mobile bracket of the utility model includes a gantry bottom plate 1, a forklift gantry 2, a mounting block 3, a roller mounting seat 6, and a roller 5. The stepper motor 10 on the forklift gantry 2 drives the forklift gantry 2 and the gantry bottom plate 1 to move forward or backward through a synchronous belt 17, and the roller 5 installed at the rear end of the gantry bottom plate 1 supports the movement of the gantry bottom plate 1, and the two rollers 5 can touch the ground at the same time, and the force is evenly applied.

[0019] The forklift mast 2 is fixedly mounted on the rear of the mast bottom plate 1, the side of the mounting block 3 is fixedly mounted on the inner side of the forklift mast 2, and the bottom of the mounting block 3 is mounted on the upper surface of the rear end of the mast bottom plate 1. A rotatable mounting shaft 4 is mounted on the mounting block 3, and a roller mounting seat 6 is rotatably mounted on the mounting shaft 4, and the roller mounting seat 6 rotates synchronously with the mounting shaft 4. A through slot is provided in the roller mounting seat 6, and a transmission shaft 7 passes through the through slot in the roller mounting seat 6, and both ends of the transmission shaft 7 are rotatably connected to two rollers 5.

[0020] When the mast bottom plate 1 moves, the two rollers 5 at the rear end of the mast bottom plate 1 support the mast bottom plate 1 to move, and the two rollers 5 installed on the same transmission shaft 7 can keep moving at the same speed. When the mast bottom plate 1 bears a heavy object, if one roller 5 touches the ground and the other roller 5 is suspended, the roller mounting seat 6 rotates to adjust the two rollers 5 to touch the ground at the same time.

[0021] Two sets of AGV forklift mobile brackets are placed in parallel, and the forklift connecting plate 8 is installed between the two forklift masts 2. The left and right ends of the forklift connecting plate 8 are respectively fixedly connected to the two forklift masts 2.
