Winding drum device, braking method for winding drum device and winch

The invention relates to a winding drum device, a braking method for the winding drum device and a winch. The winding drum device comprises a winding drum and further comprises a brake, a suspension rope used for suspending a weight is wound around the winding drum, the winding drum can rotate so as to wind or release the suspension rope to enable the weight to ascend or descend, a first gear partis arranged on the winding drum, the brake comprises a second gear part, and the second gear part meshes with the first gear part so as to enable the brake to be connected to the winding drum. According to the winding drum device, the winding drum can be braked in time, and therefore the phenomenon that the winding drum disarranges the rope can be avoided, and the working efficiency of the winding drum device is further improved. 本发明涉及卷筒装置及其制动方法以及绞车，其中，卷筒装置包括：卷筒，所述卷筒上缠绕有用以悬吊重物的悬吊绳，所述卷筒能够转动进而缠绕或释放所述悬吊绳以使所述重物上升或下降，所述卷筒上设置有第一齿轮件，所述卷筒装置还包括制动器，所述制动器包括有第二齿轮件，所述第二齿轮件与所述第一齿轮件啮合以使所述制动器连接于所述卷筒。本发明实施例的卷筒装置可对卷筒及时制动，从而避免卷筒乱绳，进而提高
