| description | The utility model discloses a hydraulic support direction adjusting device which comprises an upper circular plate and a lower circular plate which are coaxially arranged at intervals in an up-down mode, annular inner grooves and annular outer grooves are coaxially formed in the ends, close to each other, of the upper circular plate and the lower circular plate, and the inner grooves in the upper circular plate and the lower circular plate correspond to each other in the up-down mode to form an inner containing chamber. The outer grooves in the upper circular plate and the lower circular plate correspond up and down to form an outer containing chamber, and a plurality of steel balls are arranged in the outer containing chamber and the inner containing chamber in a matched mode. According to the direction adjusting device for the hydraulic support, the hydraulic support can be rapidly adjusted in direction and stably installed, the phenomenon that the support collides with a chute in the direction adjusting pr |
