MOVING BRACKET FOR TUNNEL

摘要

PURPOSE: A moving bracket for a tunnel is provide to improve the convenience by enlarging a control range of a rotatory angle of an up-and-down rotatory bracket. CONSTITUTION: A fixing bracket support metal device(30) is provided on left and right sides of a frame(32) and comprised of a flange unit(34) that is fixed on a wall of a tunnel by anchor bolts. A rotatory angle controlling plate(40) is fixed and installed on both sides of an inner surface of the frame(32). A parabolic-shaped long hole(42) is formed on a side of the rotatory angle controlling plate(40). An up-and-down rotatory bracket(50) is provided between the rotatory angle controlling plates(40) and fixed on the parabolic-shaped long hole(42) by a bolt(52). An up-and-down rotatory angle of an up-and-down rotatory bracket(50) is controlled within a length range of the parabolic-shaped long hole(42). A left-and-right rotatory bracket(60) is installed on the up-and-down rotatory bracket(50) so as to perform the left-and-right rotating, and coupled to a support round(13) and an insulation rod sequentially.
