The invention discloses a crane winding device with a steel wire rope straining mechanism. The crane winding device with the steel wire rope straining mechanism comprises a winding drum part, a motor and a speed reduction system, a one-way bearing is installed in a winding drum, the inner ring of the one-way bearing is matched with a transmission shaft, and the outer ring of the one-way bearing is matched with the winding drum; the steel wire rope straining mechanism is installed on one side of the winding drum and comprises a ratchet wheel, a pawl, a support and a limiting block, the ratchet wheel is connected to an end cap of the winding drum, ratchet wheel slots are formed in the periphery of the ratchet wheel at intervals, the pawl is installed on the support, embedded into the ratchet wheel slots under the action of a compressed spring and meshed with the ratchet wheel slots, the support is provided with an arc-shaped section which is provided with a groove, a brake cable is placed in the groove, one end of the brake cable is fixedly connected with the support, and the other end of the brake cable is connected with a manipulation handle; when the handle is pressed down, the support is made to rotate in the tension direction, the winding drum rotates along with the support to strain the steel wire rope; a torsional spring is installed between the support and a bearing seat, when the handle is loosened, the support returns to the original position under the action of the torsional spring, and the limiting block is installed on the bearing seat to make the pawl break away from the ratchet wheel slots. According to the crane winding device with the steel wire rope straining mechanism, the structure is compact, the design is reasonable, and straining of the steel wire rope is safe and reliable.
