The invention discloses a manual release mechanism for a belt brake device. The manual release mechanism comprises a release cylinder; the manual relieving fixed flange seat assembly is fixedly arranged on the relieving air cylinder and comprises a ratchet wheel; the manual release pull rope assembly is connected to the manual release fixed flange seat assembly, the manual release pull rope assembly comprises a ratchet pin mounting seat, and a ratchet pin is arranged in the manual release pull rope assembly; the relieving arm sliding seat assembly is connected to the relieving air cylinder; one end of the multi-head lead screw is connected to the relieving arm sliding seat assembly, and the ratchet wheel is arranged at the other end of the multi-head lead screw in a sleeving mode. During normal work, the ratchet wheel is separated from the ratchet wheel pin, so that the multi-head screw rod is not locked, and the belt type braking device outputs braking force normally; during manual release, the ratchet wheel pin is clamped into the ratchet wheel by driving the hand release pull rope assembly, after the multi-head lead screw is locked in one direction, the multi-head lead screw is screwed in the rotatable direction of the ratchet wheel, and the release arm sliding seat assembly is driven by the thread lift force provided by the multi-head lead screw to provide release force for brake release.
本申请公开了一种用于带式制动装置的手动缓解机构,包括:缓解气缸;手缓解固定法兰座组成固设于缓解气缸上,手缓解固定法兰座组成包括棘轮;手缓解拉绳组成连接于手缓解固定法兰座组成,手缓解拉绳组成包括棘轮销安装座,手缓解拉绳组成内装设有棘轮销;缓解臂滑动座组成连接于缓解气缸;多头丝杆其一端连接于缓解臂滑动座组成,棘轮套设于多头丝杆的另一端;正常工作时,棘轮与棘轮销保持脱开使多头丝杆未锁止,从而使得带式制动装置正常输出制动力;手动缓解时,通过驱动手缓解拉绳组成使得棘轮销卡入棘轮,对多头丝杆进行单向锁止后,沿棘轮可转动方向拧动多头丝杆通过多头丝杆提供的螺纹升力驱动缓解臂滑动座组成提供缓解力进行制动缓解。
