    • A boring apparatus, such as a drilling apparatus for forming holes in pressurised pipes, comprises a cutting head (5) mounted to a distal end of a boring bar (2) which is itself connected to a feed screw (3) by a feed nut so that relative rotation between the boring bar (2) and the feed screw (3) cause the cutting head (5) and boring bar (2) to traverse axially along the feed screw (3) whilst the cutting head (5) is rotated for cutting. The apparatus has a main drive motor arranged to drive the cutting head (5), boring bar (2) and a main drive shaft (4). The main drive shaft (4) and the feed screw (3) are operably connected at the proximal end through a pair of adjacent coaxial planetary gear assemblie (6) whose planetary gear carriers are liked to rotate in unison about the axis. An independent, primary feed drive motor is geared to a planetary gear ring (20) and is operable to provide a difference in rotation velocities between the feed screw (3) and boring bar (2) whereby the movement of the cutting head (5) and boring bar (2) to and from along the axis may be controlled.
    • 诸如用于在加压管中形成孔的钻孔装置的钻孔装置包括安装到镗杆(2)的远端的切割头(5),该钻头本身通过进给螺母连接到进给螺杆(3) 使得镗杆(2)和进给螺杆(3)之间的相对旋转使得切割头(5)和镗杆(2)沿着进给螺杆(3)轴向地横移,同时切割头(5)旋转 用于切割。 该装置具有驱动切割头(5),镗杆(2)和主驱动轴(4)的主驱动马达。 主驱动轴(4)和进给螺杆(3)通过一对相邻的同轴行星齿轮组件(6)在近端可操作地连接,其行星齿轮架希望围绕轴线一致地旋转。 独立的主进给驱动马达适用于行星齿轮环(20),并且可操作以提供进给螺杆(3)和钻杆(2)之间的旋转速度差,由此切割头(5)的运动, 并且可以控制钻杆(2)沿着轴线和从其移动。

    • A closure assembly for terminating an end of a pipe (4) has an end- cap (4) holding and having fluid- tight connection to a mutually coaxial cylindrical plug (2) and circular collar (3). The plug (2) and the collar (3) are configurable between respective engaged and disengaged configurations and mutually spaced to provide an annular space therebetween when the plug (2) and collar (3) are in their disengaged configurations. The annular space is arranged to receive an end of a pipe (1) arranged coaxially with the plug (2) and collar (3), the plug (2) and collar (3) being respectively slidable into and over the end of the pipe (1). The plug (2), when in its engaged configuration, grips the inner face of said pipe (41) and to provide a fluid tight seal and the collar (3), when in its engaged configuration, grips the outer face of the pipe (1) and to provide a fluid tight seal.
    • 用于端接管(4)的端部的封闭组件具有保持并具有与相互同轴的圆柱塞(2)和圆环(3)的流体密封连接的端盖(4)。 插头(2)和套环(3)可配置在相应的接合和分离构造之间,并且当插头(2)和套环(3)处于其分离构造时,它们之间相互间隔开,以提供它们之间的环形空间。 环形空间被布置成接收与塞子(2)和轴环(3)同轴布置的管道(1)的端部,塞子(2)和轴环(3)可分别滑入管道的端部和上方 (1)。 当塞子(2)处于其接合构型时,握住所述管道(41)的内表面并提供流体密封密封件,并且当处于其接合构造时,所述塞子(3)夹住所述管道(41)的外表面 1)并提供流体密封。
