Abstract
The utility model discloses a kind of for extremely thin coal seam hydraulic support collaborative auxiliary positioning device of moving support, comprising: circuit storage box (1), same laser receiver (2), upper laser receiver (3), lower laser receiver (4), laser transmitter (5), hoop (6). Device uses the support of completed moving support as positioning reference, moves support guidance is carried out to adjacent hydraulic support by laser mode, and the comparison information of different support support height can be obtained. The device can significantly improve the moving support precision of extremely thin coal seam hydraulic support, effectively avoid the risks such as support countersunk, extremely thin coal seam collapse, and adjacent support support height information can be fed back simultaneously, to make guiding opinion for subsequent adjustment support height.
