Zusammenfassung: | The utility model relates to a hoisting device applied to underground coal mine heavy object pulling, in particular to a bilateral control device for emergency braking of a double-speed winch. The control device comprises a winch emergency brake rod, an intermediate connection rod, a rotating rod, a fixed shaft and a fixed base. The bilateral control device is simple in structure and convenient to operate, refitting of a winch emergency brake is completed through coaxial control, the emergency brake action can be achieved by only pulling the intermediate connection rod by hand in the use process, the aims of emergency braking is achieved, the bilateral control of the emergency brake is achieved, and the problem that due to the stabilization direction, emergency brake of a winch can not be used is solved. |
