The utility model relates to a be used for directional steel wire freely suspended detection device of shaft belongs to secret mine shaft connection survey equipment technical field. Technical schemeis: contain reinforcing bar circle (1) and connect buckle (2), reinforcing bar circle (1) is the round opening column structure, connect buckle (2) contain connect steel wire (3) and with be connectedspring (4) that steel wire (3) are connected, it is connected with the both ends of reinforcing bar circle (1) respectively to connect steel wire (3) and spring (4). In the flagging back of directional steel wire, on last inferior officer's reinforcing bar snare of well head collar set arrives directional steel wire to connected connect buckle, then let the reinforcing bar circle along directional steel wire free falling. If orientation plane department in the pit can be fallen down smoothly to the reinforcing bar circle, explain then that the free vertical of directional steel wire hangs, can satisfy the directional requirement of shaft, the beneficial effects of the utility model are that: easy operation has not only improved the directional job schedule of shaft, has more guaranteed shaft directional accuracy.
