The invention relates to the field of winches, in particular to a coal mine underground conveying winch. A coal mine underground conveying winch comprises a guiding device and a locking device, a driving device drives a roller to rotate in the forward direction, after transmission of a transmission device, a sliding block slides left and right in a reciprocating mode along a support, and the sliding block drives the guiding device to slide left and right in a reciprocating mode along a fixing rod. Rotation of the roller and synchronous movement of the first clamping rod and the second clamping rod enable the steel ropes to be evenly arranged on the roller when the steel ropes slide between the first clamping rod and the second clamping rod. When a heavy object at the other end connected with the steel rope is overweight or the motor breaks down, the roller rotates reversely, and when the reverse rotation value of the roller is larger than a preset value, the sliding block rapidly slides left and right on the support in a reciprocating mode, the first clamping rod and the second clamping rod get close to each other, and the steel rope is clamped to prevent the steel rope from sliding between the first clamping rod and the second clamping rod. Serious safety accidents caused by heavy object sliding are avoided.
本发明涉及绞盘领域,具体涉及一种煤矿井下输送绞车。一种煤矿井下输送绞车包括导向装置和锁止装置,驱动装置驱动滚筒正向转动,经过传动装置传动后,使滑动块沿支架左右往复滑动,滑动块带动导向装置沿固定杆左右往复滑动,在滑动块滑动时,滚筒的转动与第一夹持杆和第二夹持杆同步运动,使钢绳在第一夹持杆和第二夹持杆之间滑动时,在滚筒上均匀排列;在与钢绳连接的另一端的重物超重或者电机发生故障时,滚筒反向转动,在滚筒反向转动大于预设值时,滑动块在支架上快速左右往复滑动,第一夹持杆与第二夹持杆相互靠近,夹紧钢绳阻碍钢绳在第一夹持杆与第二夹持杆之间滑动,避免因重物滑落造成严重安全事故。
