Ferry device of gate-type hydraulic support for coal mine

The invention discloses a ferrying device of a gate-type hydraulic support for a coal mine. The ferrying device comprises a sliding seat, a connecting seat, a swing arm, a swing driving part, a bearing disc and a lifting driving part, wherein the sliding seat is arranged in a sliding manner; the two ends of the swing arm are hinged to the sliding seat and the connecting seat respectively; the gate-type hydraulic support firstly descends and shrinks in the height direction, the sliding seat drives the bearing disc to synchronously slide until the bearing disc moves to the position under the gate-type hydraulic support, and then the lifting driving piece drives the bearing disc to ascend until the gate-type hydraulic support is supported by the bearing disc; the gate-type hydraulic support retracts the supporting legs and shrinks along the width, and the swing driving piece drives the bearing disc to swing synchronously through the swing arm till the gate-type hydraulic support swings to the target position.
