The invention discloses a limiting device of a built-in lifting winch, and relates to the field of winches. The built-in lifting winch comprises a winch base, a speed reducer support fixed to the winch base, a built-in speed reducer installed on the speed reducer support and a winding drum connected with the built-in speed reducer. The limiting device comprises a first gear detachably and fixedly connected to the outer edge of the output end of the built-in speed reducer, the first gear is meshed with a second gear installed on a rotating shaft of a stroke limiting stopper, and the stroke limiting stopper is fixed to a speed reducer support. Rotation data of the winding drum is accurately transmitted to the stroke limiter through the pair of meshing gears installed on the outer edge of the output end of the built-in speed reducer, electric signal rotation data are obtained through conversion of the stroke limiter and conveniently and rapidly transmitted to the control system, and the rotation speed of the winding drum is increased through conversion of the control system. And the rope winding and unwinding conditions of the winch and the height position of the lifting hook can be monitored in real time.

    本申请公开了一种内藏式起升卷扬的限位装置,涉及卷扬机领域。内藏式起升卷扬包括卷扬底座、固定在卷扬底座上的减速机支架、安装在减速机支架上的内藏式减速机以及与内藏式减速机连接的卷筒。限位装置包括可拆卸固定连接在内藏式减速机输出端外缘的第一齿轮,第一齿轮与安装在行程限位器的转轴上的第二齿轮啮合,行程限位器固定在减速机支架上。本申请通过安装在内藏式减速机输出端外缘上的一对啮合齿轮,将卷筒的转动数据,精准传递给行程限位器,经由行程限位器转换得到电信号转动数据,方便、快捷地输送到控制系统,通过控制系统的换算,即可实时监控卷扬卷放绳情况及吊钩的高度位置。
