The invention relates to the technical field of winch braking and discloses a hoisting winch for a hydraulic engineering ship. The hoisting winch comprises a driving motor, a brake mechanism and a brake wheel. A driving gear is fixedly connected to the top end of a transmission shaft of the driving motor in a sleeving manner, an electromagnetic coil is fixedly mounted on the lower portion of an electromagnet armature on the brake mechanism, the end surface, located on one side of the driving motor, of the brake wheel is fixedly connected to an inner gear, and a driven gear is in transmission connection between the driving gear and the inner gear. As the driving gear is arranged on the transmission shaft of the driving motor, the end surface of the brake wheel is fixedly connected to the inner gear, and the driving gear is in transmission connection to the inner gear through the driving gear, it is ensured that when the brake wheel is in brake lock, the driving motor still can rotate and drive the driven gear to rotate around the inner gear, such that a huge torque generated by sudden brake lock of the brake wheel is alleviated effectively and conditions, for example, damage of thetransmission shaft of the motor, and the like are avoided.

    本发明涉及卷扬机制动技术领域,且公开了一种水利船舶用起重卷扬机,包括驱动电机、制动机构和制动轮,所述驱动电机传动轴的顶端固定套接有主动齿轮,所述制动机构上电磁衔铁的下部固定安装有电磁线圈,所述制动轮位于驱动电机一侧的端面固定连接有内齿轮,所述主动齿轮与内齿轮之间传动连接有从动齿轮。本发明通过在驱动电机的传动轴上设有主动齿轮,通过制动轮的端面固定连接内齿轮,主动齿轮与内齿轮通过从动齿轮传动连接,保证了制动轮在被制动抱死时,驱动电机仍可以转动并带动从动齿轮围绕内齿轮转动,有效的缓解了制动轮突然抱死时产生的巨大扭矩,避免了造成电机传动轴损坏等情况。
