The invention relates to the technical field of winches, and discloses a winch stall self-locking structure utilizing an electromagnetic variant principle. The winch stall self-locking structure comprises a mounting seat, a shell is fixedly connected to the front surface of the mounting seat, a winding disc is fixedly connected to the front surface of the shell, a fixing screw rod is movably connected to the side surface of the shell, and a fixing box is arranged on the front surface of the shell; and a twisted rope is movably connected to the interior of the fixing box. Through cooperative use of a self-locking block and a self-locking piece, when the winch stalls in use, automatic self-locking is achieved, the situation that due to the fact that the rotating speed is too high and cannot be controlled, a vehicle is trapped for the second time, and even economic losses are caused by vehicle damage is avoided, and the service life of parts in the winch is prolonged to a certain degree; and meanwhile, through cooperative use of the fixing box and the fixing screw rod, the twisted rope can be evenly wound on the winding disc when the twisted rope is wound, the rope head can be fixed after winding is completed, and the stability of the twisted rope is guaranteed.
本发明涉及绞盘技术领域,且公开了一种利用电磁变体原理的绞盘失速自锁结构,包括安装座,所述安装座的正面固定连接有壳体,所述壳体的正面固定连接有卷绕盘,所述壳体的侧面活动连接有固定螺杆,所述壳体的正面设置有固定盒,所述固定盒的内部活动连接有绞绳;通过自锁块和自锁片的配合使用,当绞盘使用时发生失速情况下,自动自锁,避免了因为转速过快,控制不了而导致车辆二次受困甚至车辆损伤造成的经济损失,也会在一定程度上增加了绞盘内部零部件的使用寿命;同时通过固定盒和固定螺杆的配合使用,在收卷绞绳时可以让绞绳均匀缠绕在卷绕盘上,收卷完成后,还可以固定住绳头,保证了绞绳的稳定性。
