The limiting device comprises a bearing beam, the top face of the bearing beam is rotationally connected with a rotating shaft, the peripheral wall of the rotating shaft is rotationally connected with two cross beams, the top face of the cross beam at the top is provided with a movable hole, and the top face of the cross beam at the top is provided with a through hole. A limiting block with the top end extending into the movable hole and slidably connected with the movable hole is fixed to the top face of the bearing beam, two circular holes are formed in the top face of the bearing beam, spherical shafts are slidably connected into the circular holes, fixing assemblies used for fixing the spherical shafts are arranged in the circular holes, and a bearing trolley is rotationally connected to the top faces of the spherical shafts. According to the limiting device for the heavy ultrathin hydraulic cylinder hoisting beam to pass through the curve, when the hoisting beam is pushed to pass through the curve, the limiting block limits the overlarge included angle between the bearing beam and the track, the bearing beam is prevented from freely rotating to rub and collide with an H-shaped beam, the problem that the track is twisted or even falls off due to the overlarge included angle between the bearing beam and the track is solved, and it is guaranteed that a locomotive safely passes through the curve.

    本发明涉及一种重型超薄液压缸起吊梁过弯道的限位装置,包括承载梁,所述承载梁的顶面转动连接有转轴,所述转轴的外周壁上转动连接有两个横梁,顶部所述横梁的顶面开设有活动孔,所述承载梁的顶面固定有顶端延伸至活动孔内部并与其滑动连接的限位块,所述承载梁的顶面开设有两个圆形孔,所述圆形孔内滑动连接有球面轴,所述圆形孔内设有用于固定球面轴的固定组件,所述球面轴的顶面转动连接有承载小车。该重型超薄液压缸起吊梁过弯道的限位装置,在起吊梁受推力过弯道时,限位块限制承载梁与轨道夹角过大,防止承载梁自由旋转与H型梁剐蹭碰撞,防止承载梁与轨道夹角过大造成轨道拧轨甚至轨道脱落的问题,保证机车安全通过弯道。
