摘要： A tool for vertically supporting a shroud repair tie rod assembly having a clevis hook by bracing the clevis hook against a clevis pin incorporated on a lower support fixture toggle-bolted to the shroud support plate. The provision of vertical support at the bottom of the tie rod assembly allows the vertical support at the top of the tie rod assembly to be removed, so that the upper support structure can be coupled to the threaded upper end of the tie rod. The lower end of the tie rod assembly is supported on both sides of a vertical support plate of the fixture. The tool for vertically supporting the lower end of the tie rod assembly comprises a support frame which sits on the top surface of a fixture bracket while receiving the coupled toggle bolt and nut in a recess that allows the tool to rotate about the axis of the toggle bolt. The vertical support tool includes a pivotable locking arm with a channel for receiving a rope, by means of which the tool can be raised and lowered by maintenance personnel standing on the refueling bridge. A threaded hydraulic cylinder is installed in the support frame so that its piston lies directly underneath a bottom surface of one arm of the clevis hook and extends vertically upward in response to cylinder actuation. In the extended position, the distal end of the piston bears against the bottom surface of the clevis hook with sufficient force to vertically support the tie rod assembly against the clevis pin.

摘要： A tool for installing and torquing a tensioning nut onto a tie rod of a shroud repair apparatus. The nut torquing tool has a socket for coupling with the tensioning nut and an adaptor for coupling with a manually operated handling pole, wherein the axis of rotation of the socket is radially displaced relative to the axis of rotation of the adaptor. The respective shafts connected to the socket and adaptor are coupled by means of a pair of sprockets and a chain which convert rotation of the adaptor into rotation of the socket. The distance between the sprockets can be adjusted to tension the chain. The handling pole adaptor is connected to a drive shaft by way of a universal joint, a torque limiter and a torque multiplier. Incorporation of a torque multiplier facilitates installation and torquing of the tensioning nut in a single operation using a lightweight handling pole.

摘要： A tool for installing a support member which must be rotated into a horizontal position in the downcomer annulus of a boiling water reactor by remote manipulation. The support member may, for example, be a midsupport for damping flow-induced vibrations in a vertical restraint tie rod. The tool includes a rigid holder for holding the support member and a threaded pivot for coupling with the threaded end of a cable. The pivot can swing relative to the holder between first and second angular positions separated by 90.degree.. The support member is held in the holder by a pair of channels formed on the holder and a set screw which threads in the holder and enters a bore formed in the support member. After the support member has been secured to the holder, the holder is coupled to the end of the cable via the pivot. The support member is lowered in the downcomer annulus in a vertical position. When the support member reaches the installation elevation, the support member is pivoted into a horizontal position for engagement with the tie rod. The tool is disengaged from the installed support member by remote manipulation of the set screw.

摘要翻译： 用于安装支撑构件的工具，该支撑构件必须通过远程操纵旋转到沸水反应堆的降液管环中的水平位置。 支撑构件可以例如是用于阻止垂直约束拉杆中的流动振动的中间支撑。 该工具包括用于保持支撑构件的刚性保持器和用于与电缆的螺纹端连接的螺纹枢轴。 枢轴在相隔90°的第一和第二角度位置之间相对于支架摆动。 支撑构件通过形成在保持器上的一对通道和固定螺钉保持在保持器中，该螺钉在保持器中螺纹并进入形成在支撑构件中的孔中。 在支撑构件已经固定到保持器之后，保持器经由枢轴联接到电缆的端部。 支撑构件在垂直位置下降到降液管环中。 当支撑构件到达安装高度时，支撑构件枢转到水平位置以与拉杆接合。 通过远程操作固定螺丝，该工具与安装的支撑构件脱离接合。
