Novel cable drum based on bidirectional ratchet wheel

The invention discloses a novel cable drum based on a bidirectional ratchet wheel. The novel cable drum comprises a rotating shaft; the wire coil main body sleeves the rotating shaft in the axial direction of the rotating shaft and is used for winding a cable; the bidirectional ratchet wheel mechanism comprises a ratchet wheel and a pawl matched with the ratchet wheel, and the ratchet wheel and the pawl are arranged on the rotating shaft and the wire coil body respectively; and one end of the rotating shaft is fixed on the bracket. Through the bidirectional ratchet wheel structure, the rotation controllability of the wire coil is improved, the problem of excessive rotation caused by rotational inertia when the wire coil is wound and unwound is effectively solved, the rotation of the wire coil is well controlled, the workload of workers during winding and unwinding is reduced, the winding and unwinding track of a cable is limited within a certain range, and the winding and unwinding efficiency of the cable is
