[0019] As a specific implementation of this embodiment, the brake mechanism includes a pneumatic tendon 23, a joint 24, a movable frame 22, a pressure plate 11, a friction plate 7, a pin 8, a spring 9, and a nut 10; the two ends of the pneumatic tendon 23 are connected to the joint 24, the joint 24 is installed on the first diagonal of the movable frame 22, and the second diagonal of the movable frame 22 is respectively hingedly connected with the pressure plate 11, the friction plate 7 and the spring 9 are sleeved on the wheel axle 2, the friction plate 7 is close to the inner side of the frame, the pin 8 passes through the friction plate 7 and the wheel axle 2, so that the pin 8, the friction plate 7 and the wheel axle 2 are fixed together, the friction plate 7 realizes the torque transmission from the friction plate 7 to the wheel axle 2 through the pin 8, the wheel axle 2 passes through the pressure plate 11, the two ends of the spring 9 are respectively against the friction plate 7 and the pressure plate 11, and the wheel axle 2 is also equipped with a useful Regarding the nut 10 for limiting the pressure plate 11, the spring 9 is located on the side where the pressure plate 11 is located and the nut 10 is located on the side where the pressure plate 11 is located opposite to the side where the pressure plate 11 is located; the pneumatic tendon 23 is parallel to the fixed seat 17 and is located below the central area of ​​the fixed seat 17; when the pneumatic tendon 23 contracts, the first diagonal corner of the movable frame 22 contracts accordingly, and the second diagonal corner of the movable frame 22 extends outward, that is, the second diagonal corner of the movable frame 22 moves away from the pneumatic tendon 23, that is, the second diagonal corner of the movable frame 22 drives the pressure plate 11 to move in the direction of the cross plate 25; conversely, the pneumatic tendon 23 extends, the first diagonal corner of the movable frame 22 extends accordingly, and the second diagonal corner of the movable frame 22 closes inward, that is, the second diagonal corner of the movable frame 22 moves toward the direction of the pneumatic tendon 23.

At this time, the conveyor line needs to brake quickly, and the pneumatic tendon 23 contracts, driving the first diagonal of the movable frame 22 to shrink inward. At the same time, the second diagonal of the movable frame 22 extends outward, and the second diagonal of the movable frame 22 pushes the pressure plate 11 to compress the spring 9, and the pressure plate 11 is separated from the nut 10.

When the pressure plate 11 contacts the nut 10, the pressure plate 11 is prevented by the nut 10 from continuing to move in the direction of the pneumatic tendon 23. At this time, the pressure on the friction plate 7 is relieved, and the clutch 12 continues to work, the reduction motor 21 rotates, driving the walking mechanism to operate, so that the roller 1 rotates and drives the frame to move.

[0024] In this embodiment, the control system applies pressure to the pneumatic muscle 23 to cause the pneumatic muscle 23 to contract or extend, thereby controlling the walking mechanism to brake or release the brake.

[0025] By using an efficient and reliable brake mechanism, it is possible to quickly respond to brake commands, reduce energy loss during parking, and extend the overall service life of the equipment by improving system stability and reducing mechanical wear. The design of the pneumatic tendon 23 and the movable frame 22 enables it to quickly and accurately control the pressure, change the position of the pressure plate 11, thereby reducing friction energy consumption and achieving stable braking. By setting a brake mechanism on the walking mechanism, the accuracy and force control of the braking process are improved.
