[0026] When in use, the main drum 1 is fixedly installed on the workover rig. When the braking device 2 needs to be installed, the braking device 2 is placed on the placement plate 301. Through the disassembly and assembly mechanism 3, the braking device 2 can be quickly and conveniently disassembled and assembled, making it more convenient to use.

[0029] When in use, the main drum 1 is fixedly installed on the workover rig. When the braking device 2 needs to be installed, the braking device 2 is placed on the placing plate 301. The disassembly and assembly mechanism 3 can quickly and conveniently disassemble and assemble the braking device 2, making it more convenient to use. When vibrations occur during use, the shock absorption mechanism 4 is used for shock absorption and buffering, thus enabling better use and improving the stability of the braking device. When an external object impacts the braking device 2 during use, the protective plate 505 can block the object. The movement of the protective plate 505 drives the movement of the connecting plate 504. The movement of the connecting plate 504 drives the movement of the buffer rod 503. The movement of the buffer rod 503 drives the buffer plate 502 to slide on the inner wall of the buffer box 501. The sliding of the buffer plate 502 compresses the spring four. The movement of the connecting plate 504 can compress the damper two 506, thereby achieving shock absorption and buffering, and better protecting the braking device 2, effectively reducing the damage of the braking device 2 during use.
