The invention provides a hoisting winch which comprises a base, two supporting seats are arranged at the top of the base side by side, a winding drum is rotationally connected between the two supporting seats, a steel cable is wound on the outer side of the winding drum, one end of the steel cable is fixedly connected with the outer wall of the winding drum, and a hoisting motor is arranged at the top of the base and is parallel to the winding drum. A hoisting speed reducer is arranged at the top of the base, the input end of the hoisting speed reducer is connected with a hoisting motor, the output end of the hoisting speed reducer is connected with the winding drum, the two supporting bases are the first supporting base close to the hoisting speed reducer and the second supporting base away from the hoisting speed reducer, and a protection device is arranged between the second supporting base and the winding drum. The protection device is used for limiting unidirectional rotation of the reel. If the motor breaks down in the heavy object lifting process, the protection device can limit reverse rotation of the winding drum, then the heavy object is prevented from falling rapidly under the self-weight effect, and potential safety hazards during use of the winch are reduced.
本发明提供了一种吊装卷扬机,包括底座,底座的顶部并排设置有两座支撑座,两座支撑座之间转动连接有卷筒,卷筒的外侧缠绕有钢索,且钢索的一端与卷筒的外壁固定连接,底座的顶部设置有吊装电机,吊装电机与卷筒并排,底座的顶部设置有吊装减速器,吊装减速器的输入端与吊装电机连接,吊装减速器的输出端与卷筒连接,两支撑座分别为靠近吊装减速器的第一支撑座以及远离吊装减速器的第二支撑座,第二支撑座与卷筒之间设置有防护装置,防护装置用以限制卷筒单向转动。若在起吊重物过程中电机出现故障,则防护装置可限制卷筒反向转动,进而防止重物在自重作用下飞速下坠,并降低上述卷扬机使用时的安全隐患。
