摘要
The present invention relates to a width variable tongseu crane and the deviation compensator to the width of the left and right barrel (Tong) having a variation compensation unit for compensating for the difference in height being variable and the supporting block (Block Supporting) right and left at the same time. ; To achieve, the invention is a top drive unit (30) for right and left to move the upper portion of the tongseu part 50 by the upper screw bar 35 connected to the drive motor 33 at the top of the upper beam 32, the left and right tongseu and unit lower drive 70 consisting of a drive motor (74) and the lower screw bars 76 on top of the lower beam 72 to move left and right to the bottom of 50, the right and left sides of the lower beam (72) a pair of supporting block unit is fixed having an independent drive motor (91) the rules for the elevator 90 and the upper beam (31) fixed at the bottom tongki cylinder 112 and the lower portion to secure to accommodate this provides a variable width tongseu crane having an automatic deviation compensation unit characterized in that it consists of the moving tongki 110 composed of an tongki casing 114 fixed to the upper beam (72). ; The present invention is a flexible rotating cable 121 for coupling the gear and the bevel gear 92 formed in the drive motor 91 of the supporting block portion 90 in order to compensate for the height variation of the right and left supporting block portion 90 'and, the pair of sensing plates (120 and 120 of a pair of sensing plates (120 and 120), which is fixed to view mutual facing the seating insert the other end also acceptable to rotate a) and the bearing (181) to secure to at the same time one is formed pair, and the pair of sensing plates (120 and 120 of the housing (180 180), formed on) one side groove (123 123 ') fixed link fixing plate (141 141 a "), the power contact plates (142 142'), and the touch bar (145 145 the other side of the ") power source contact portion 140 and the power contact 140, a pair of sensing plates (120 and 120 is formed composed of a ') groove (124 124') to link the fixed plate (141 141 '), a vertical link (163 163 '), a horizontal link (165 165' provides automatic deviation compensation device, it characterized in that the operation consisting of a variable portion 160 made of a) and touch the stop bar (167 167 '). ; Thus, the present invention has a pair by using a deviation automatic compensation apparatus for the same time and can be transferred to steel slabs of various lengths compensate for the height variation of the supporting block to control the slab both in the width adjustable tongseu cranes supporting block maintaining the same height at all times level, there is an effect that can detect certain steel slab. ; Variable width, tongseu cranes, deviation compensation unit, screw bar, the supporting block
