Abstract

The utility model discloses a convenient temporary support device for coal mining, which comprises a support body, thread bushings are coaxially arranged at the upper end and the lower end of the support body, screw rods are in threaded fit with the thread bushings, the thread turning directions of the upper screw rod and the lower screw rod are opposite, and when the support body rotates towards one side, the support body rotates towards the other side. The upper screw rod and the lower screw rod move in opposite directions; a supporting plate is arranged at the outer end of the screw rod; the height of the device can be contracted, the device can be conveniently carried and moved in a narrow coal seam channel, and after the device reaches an excavation position, the height of the device can be lengthened, so that the upper supporting plate and the lower supporting plate are supported on the top face and the bottom face of the coal seam channel respectively, the supporting effect on ore above the coal seam channel is achieved, small collapse can be coped, and the device is convenient to use. And an effect of protecting mining workers is achieved.
