TWO-HEAD TYPE BOLT FASTENING/LOOSENING DEVICE
To simultaneously efficiently loosen and fasten the nuts and bolts of a rail fastening device even if the type of rail fastening device changes or the variation in the position of nuts and bolts is large.SOLUTION: A two-head type bolt fastening/loosening device 11 comprises: a dolly 11 traveling on rails 4, 4; and a bolt fastening/loosening part 12 including two bolt fastening/loosening machines 12a, 12b for fastening and loosening nuts and bolts of a rail fastening device 2 for fixing the rails 4, 4. The two bolt fastening/loosening machines 12a, 12b are configured to be movable longitudinally and laterally by a horizontal rotation part 12d that rotates in a horizontal direction around a first horizontal rotation shaft part 12c provided on the dolly 11 on at least one side of the dolly 11 and above the rails 4, 4 respectively, and a pair of bolt fastening/loosening machine support parts 12g, 12h that rotate in a horizontal direction around second horizontal rotation shaft parts 12e, 12f provided on both sides of the horizontal rotation part 12d respectively, even in a state in which the dolly 11 is stopped.SELECTED DRAWING: Figure 3
【課題】レール締結装置の型が変わったり、ボルトやナットの位置のばらつきが大きい場合でも、レール締結装置のボルトやナットを同時に効率良く緩めたり、締付ける。【解決手段】２頭式ボルト緊解装置１１は、レール４，４上を走行する台車１１と、レール４，４を固定するレール締結装置２のボルトやナットを緩めたり締付ける等の緊解作業を行う２台のボルト緊解機１２ａ，１２ｂを備えたボルト緊解部１２とを有し、２台のボルト緊解機１２ａ，１２ｂは、台車１１を停止させた状態でも、それぞれ、台車１１の少なくとも一方側であってレール４，４上方の台車１１に設けられた第１水平回動軸部１２ｃを中心に水平方向に回動する水平回動部１２ｄと、水平回動部１２ｄの両側にそれぞれ設けられた第２水平回動軸部１２ｅ，１２ｆを中心に水平方向に回動する一対のボルト緊解機支持部１２ｇ，１２ｈとによって前後左右に移動可能に構成されている。【選択図】図３
