Zusammenfassung: | To provide a rail gas pressure welding machine with good workability, in which a following movement mechanism does not bulge out in a lateral direction, even in a small-sized pressure welding machine.SOLUTION: A rail gas pressure welding machine is equipped with a fixed frame 11 and a moving frame 12 that are respectively fixed to a pair of rails 10 to be pressure welded, a heating burner 13, and a compression moving amount following mechanism 15 that is provided outside the fixed frame 11 in a longitudinal direction of the rail 10, and moves the heating burner 13 by following the compression moving amount of the rail 10. The compression moving amount following mechanism 15 is equipped with a rotary arm 18 capable of horizontally rotating around a shaft provided at a fixed place, and the rotary arm 18 is coupled to the heating burner 13 at a center position between a coupled position coupled to the moving frame 12 and the shaft position.SELECTED DRAWING: Figure 1
【課題】小型の圧接機であっても、追従移動機構が横方向にはみ出すことのない、作業性の良好なレールガス圧接機を提供する。【解決手段】レールガス圧接機は、圧接すべき1対のレール10にそれぞれ取付け固定される固定フレーム11及び移動フレーム12と、加熱バーナー13と、レール10の長手方向における固定フレーム11の外側に設けられており、レール10の圧縮移動量に追従して加熱バーナー13を移動させる圧縮移動量追従機構15とを備えている。圧縮移動量追従機構15は、固定位置に設けられた軸の回りを水平方向に回動可能な回動アーム18を備えており、この回動アーム18は移動フレーム12に連結された連結位置と上述した軸の位置の中央位置で加熱バーナー13に連結されている。【選択図】図1 |
