[0024] The brake assembly includes two fixed frames 16 fixedly mounted at both ends of the top of the movable seat 14. The fixed frames 16 can be any type of fixed frames 16 that can fix the brake assembly. Two limit rods 17 are movably sleeved inside the side of the fixed frame 16. Contact rods 18 are installed at the ends of the two limit rods 17. A spring 19 is sleeved between the limit rods 17 and the contact rods 18. A second motor 20 is installed on the top of the fixed frame 16. An eccentric wheel 21 is installed on one side of the output shaft of the second motor 20 that passes through the fixed frame 16. The eccentric wheel 21 and the contact rod 18 rotates to contact, and a speed sensor 22 is fixedly provided on one side of the movable seat 14 close to the contact rod 18. Here, the eccentric wheel 21 can only be used to contact the contact rod 18. Because the larger the secondary diameter of the eccentric wheel 21 in contact with the contact rod 18 when it rotates, the higher the strength when the contact rod 18 drives the limit rod 17 to contact the inner side of the traction frame 23, and the better the effect of emergency braking. At the same time, the rotation angle of the eccentric wheel 21 is controlled at 360 degrees for one braking, and the inner side of the traction frame 23 is provided with a friction layer for increasing the friction braking with the limit rod 17.

[0025] like Figure 2 and Figure 4 As shown, the alarm component includes a buzzer 24 fixedly installed at the center of the movable seat 14. The buzzer 24 can be any device with a prompt sound. A contact end 15 is installed on the top of the buzzer 24. The buzzer 24 is in electrical contact with the contact end 15. Fixed rods 10 are provided at the four corners of the top of the traction frame 23. A sensor 11 is provided on the top of the fixed rod 10. A sensing groove 12 is provided on the side of the sensor 11 close to the contact end 15.

[0026] like Figure 1 As shown, the traction assembly includes two drive shafts 5 rotatably connected to both sides of the traction frame 23, and a transmission chain 7 is vertically sleeved on the outside of the two drive shafts 5. A first motor 4 is provided inside the bottom end of the traction frame 23, and the output shaft of the first motor 4 passes through one side of the traction frame 23 and is connected to the drive shaft 5. The drive shaft 5 is used to drive the transmission chain 7 to rotate.

[0027] like Figure 1 and Figure 4 As shown, a slide groove 6 is provided on both sides of the traction frame 23, and a fixing block 9 is fixedly provided on both sides of the movable seat 14. The fixing block 9 penetrates one side of the slide groove 6 and is fixedly sleeved on the outside of the transmission chain 7. When the movable seat 14 moves upward, the fixing block 9 on the outside slides in contact with the slide groove 6, making the movable seat 14 more stable when stable.

[0028] like Figure 1 and Figure 2As shown, a limiting groove 8 is provided on the outside of the traction frame 23, and a connecting block 25 is provided on one side of the movable seat 14 close to the limiting groove 8. The connecting block 25 penetrates through one side of the limiting groove 8 and is connected to the climbing frame fixing body 13. The stability of the climbing frame fixing body 13 sliding upward and downward in the limiting groove 8 is driven by the connecting block 25 on the movable seat 14. The connecting block 25 can be any type of connecting block 25, as long as any type of connecting block 25 is able to slide with the limiting groove 8.

[0029] like Figure 1 and Figure 4 As shown, a controller 3 is installed outside the base 2, and the second motor 20, the speed sensor 22, the sensor 11 and the first motor 4 are all electrically connected to the controller 3.

[0030] Working principle:

[0031] During use, the climbing frame to be towed is placed on the climbing frame fixed body 13, and the climbing frame is fixed with an external fixing part, and then the external power supply is turned on, the first motor 4 is driven by the controller 3, and the speed value of the climbing frame fixed body 13 when moving is verified by the controller 3, and the output shaft of the first motor 4 drives the driving shaft 5 to rotate, and then the driving shaft 5 drives the transmission chain 7 to rotate while the driving shaft 5 rotates, and the fixed block 9 is driven to move during the rotation of the transmission chain 7. At this time, the movable seat 14 connected to the fixed block 9 drives the external climbing frame fixed body 13 to move through the connecting block 25. When the movable seat 14 drives the climbing frame fixed body 13 to approach the top of the traction frame 23, the contact end 15 at the top of the movable seat 14 and the inner contact end 15 of the sensor 11 When the climbing frame 21 is in contact with the sensing groove 12 at the top, the buzzer 24 makes a sound to remind the staff to take out the climbing frame inside the climbing frame fixing body 13 in time to prevent the climbing frame from hanging on the top of the traction frame 23 for a long time. When the climbing frame fixing body 13 drives the internal climbing frame to move upward or downward, the speed sensor 22 is used to sense the moving speed. When the sensed speed is greater than the approved value of the controller 3, the second motor 20 is automatically started through the controller 3, so that the output shaft of the second motor 20 drives the eccentric wheel 21 to rotate, so that the eccentric wheel 21 and the contact rod 18 rotate and contact, and squeeze the limit rod 17 to contact the inside of the traction frame 23, so that the limit rod 17 and the inside of the traction frame 23 rub, to achieve emergency braking and avoid the expansion of losses as much as possible.
