Before maintaining the AGV transport vehicle, first use the lifting equipment to make the AGV transport vehicle be located above the placement base plate 1, and then start the motor 703. The motor 703 drives the bidirectional screw rod 708 to rotate, and the bidirectional screw rod 708 drives the front and rear sliders 709 to move away from each other, and the slider 709 drives the inclined plate 1 711 to rotate.

[0020] The upper and lower sides of the mobile box 706 are fixedly connected with two mounting blocks 716, and a control rod 717 is rotatably connected between the two mounting blocks 716. The outer sides of the upper and lower control rods 717 are fixedly connected with a stop plate 718. The front and rear ends of the control rod 717 pass through the outer side of the mounting block 716 and are fixedly connected with a control disk 719.

When the clamp 714 limits the AGV transport vehicle, the electromagnet 743 on the clamp 714 moves to the inner side of the moving box 706, and the electromagnet 743 contacts the metal block 744. When the clamp 714 clamps the AGV transport vehicle, the electromagnet 743 is started to make the electromagnet 743 and the metal block 744 adsorbed, so as to facilitate the limiting of the clamp 714 and avoid the displacement of the clamp 714 during maintenance.

Two top blocks 731 are fixedly connected to the upper and lower sides of the clamping plate 714, and a rotating rod 1 732 is rotatably connected between the two top blocks 731. A winding roller 733 is fixedly connected to the outer side of the rotating rod 1 732, and a steel cable 2 734 is arranged on the outer side of the winding roller 733. The upper and lower sides of the load-bearing block 728 are fixedly connected to the second mounting block 730, and the mounting block The second 730 is fixedly connected to the second steel cable 734, the outer end of the rotating rod 1 732 passes through the outer side of the top block 731 and is fixedly connected to the bevel gear 1 735, the outer side of the top block 731 is fixedly connected to the fixed block 738, the outer side of the fixed block 738 is rotatably connected to the second rotating rod 737, one end of the second rotating rod 737 is fixedly connected to the second bevel gear 736, the other end of the second rotating rod 737 is fixedly connected to the gear part 739, the outer side of the moving box 706 is fixedly connected to the L-shaped plate 741, the outer side of the L-shaped plate 741 is fixedly connected to the toothed plate 740, the bevel gear 1 735 and the bevel gear 2 736 is meshed and connected, gear member 739 is meshed and connected with tooth plate 740, spring 2 729 is fixedly connected between load-bearing block 728 and clamping plate 714, when clamping plate 714 limits the AGV transport vehicle, clamping plate 714 drives gear member 739 on rotating rod 2 737 to move horizontally, because gear member 739 is meshed and connected with tooth plate 740, gear member 739 rotates, gear member 739 drives rotating rod 2 737 to rotate, rotating rod 2 737 drives bevel gear 2 736 to rotate, bevel gear 2 736 drives bevel gear 1 735 to rotate, bevel gear 1 735 The rotating rod 732 is driven to rotate, and the winding roller 733 of the rotating rod 732 rotates, so that the winding roller 733 retracts the steel cable 2 734, and the steel cable 2 734 drives the load-bearing block 728 on the mounting block 2 730 to move, so that the load-bearing block 728 is close to the AGV transport vehicle, so that the load-bearing blocks 728 on the front and rear sides can limit the front and rear sides of the AGV transport vehicle, thereby enhancing the stability of the clamped AGV transport vehicle and preventing the AGV transport vehicle from falling and being damaged during maintenance. The L-shaped plate 741 and the tooth plate 740 are not in contact with the control panel 719, the inclined plate 2 721, and the control panel 723.

The direction of the vehicle rotates, so that the upper and lower sides of the abutment plates 718 can clamp and limit the upper and lower sides of the AGV transport vehicle, thereby increasing the stability of the AGV transport vehicle during maintenance. At the same time, the clamping plate 714 drives the gear part 739 on the rotating rod 2 737 to move, and under the action of the toothed plate 740, the gear part 739 is controlled to rotate.
