Abstract
The utility model discloses an upper brake arm self-locking device for a broken belt seizing machine of a belt conveyer, which is installed on an upper brake arm bracket of the broken belt seizing machine. The device comprises a fixed plate, a low support plate, a return stopping pad, a sheath, a positioning pin, and a compression spring, wherein the fixed plate is connected with the upper brake arm bracket, the return stopping pad is connected with a lower brake block via a shifting yoke, the upper end of the positioning pin is connected with a round groove at the lower end of upper brake arm, and the lower end of the positioning pin is connected with a round groove at the upper end of the return stopping pad. When the broken belt seizing machine is not working, the device allows the upper brake arm to be locked together with the upper brake arm bracket, so that the upper brake arm can not move even when the belt conveyer generates vibration, thereby preventing mistakenly seizing; and when a broken belt appears, the positioning pin automatically moves downwards under the action of the compression spring to detach from the upper brake arm, so as not to influence the seizing of the broken belt. The device provided in the utility model can be safely and reliably used.
