The invention relates to the technical field of winches, in particular to a slope winch safety protection device and a slope winch. The device comprises a first connecting shaft, a second connecting shaft, an elastic part, a first gear, a second gear, an electromagnet, a shifting piece, a first supporting seat and a second supporting seat. When the slope winch encounters sudden power failure in the transportation process, especially in the upward lifting transportation process, the electromagnet is suddenly in a power-off state, the electromagnet loses magnetism, the first gear and the secondgear can be connected together in a meshing mode under the action of resilience force of the elastic part, due to the fact that the second gear cannot rotate, after the first gear and the second gearmesh with each other, the first gear can be stuck and cannot rotate, a winding drum cannot rotate due to the rotation failure of the first gear, and the winding drum is safely braked, so that cargoesare effectively prevented from sliding downwards along a rail, the possibility of safety accidents is reduced, and the use safety of the slope winch is remarkably improved.
本发明涉及卷扬机技术领域,尤其涉及一种斜坡卷扬机安全保护装置及斜坡卷扬机,其包括第一连接轴、第二连接轴、弹性件、第一齿轮、第二齿轮、电磁铁、拨片、第一支撑座、第二支撑座,当斜坡卷扬机在运输过程中遇到突然断电时,特别是向上提升运输过程时,电磁铁也突然处于断电状态,电磁铁失去磁性,在弹性件回弹力的作用下,第一齿轮与第二齿轮能够相互啮合连接在一起,由于第二齿轮不能旋转,第一齿轮与第二齿轮相互啮合后,会使得第一齿轮被卡死,不能旋转,第一齿轮不能旋转使得卷筒不能旋转,卷筒被安全制动,从而有效地防止货物沿轨道向下滑行,降低产生安全事故的可能性,显著提高了斜坡卷扬机的使用安全性。
