摘要： A smoothing device, according to the present invention, is used to perform smoothing in a conduit line, or the like. The smoothing device has a fluid pressure motor with a cutter attached to its output shaft and guide rollers for guiding the smoothing device in the longitudinal direction of the conduit line. Prescribed ones among the guide rollers are relatively movable in the radial direction of the conduit line by fluid pressure cylinders, springs, or the like, and pressed against the inner wall of the conduit line. The remaining guide rollers are fixed to the smoothing device with respect to the radial direction of the conduit line so as to have an automatic aligning mechanism, thereby keeping the rotatable cutter along the center of the conduit line. In the fluid pressure motor, turbine and water nozzles, for injecting water to the turbine, are detachable, facilitating the replacement of worn parts. To easily advance the smoothing device, a propelling device, using a plurality of propelling shafts connected by universal joints with rollers disposed near the connected portions of the shafts and using screws, is provided. To facilitate the discharge of the removed debris and drainage, a high-pressure water jet pump is provided. The coupler absorbing the rotation is attached to the front face of the cutter thus enabling the smoothing device to be towed in the direction of the cutter with a rope.
摘要翻译： 根据本发明的平滑装置用于在导管管线等中执行平滑化。 平滑装置具有流体压力马达，其具有附接到其输出轴的切割器和用于沿着导管线的纵向方向引导平滑装置的导向辊。 导辊之间规定的导辊可以通过流体压力缸，弹簧等在管道的径向方向上相对移动，并且压靠导管线的内壁。 剩下的导辊相对于导管的径向方向固定在平滑装置上，从而具有自动对准机构，从而沿着导管线的中心保持可旋转切割器。 在流体压力马达中，用于将水喷射到涡轮机的涡轮机和水喷嘴是可拆卸的，便于更换磨损部件。 为了容易地推进平滑装置，提供了一种推进装置，其使用通过万向接头连接的多个推进轴，其中设置在轴的连接部分附近并使用螺钉的辊。 为了便于排出的碎屑和排出物，提供了高压水喷射泵。 吸收旋转的联接器附接到切割器的前表面，从而使得平滑装置能够用绳索沿切割器的方向拖曳。
