结构地更换核能发电厂中龟裂的焊接部分的设备及方法;APPARATUSES AND METHODS FOR STRUCTURALLY REPLACING CRACKED WELDS IN NUCLEAR POWER PLANTS

摘要

一种被建构来结构地更换核能发电厂中龟裂的焊接部分的设备可包括：一第一本体部分，其包括一第一抓紧部分；一第二本体部分，其包括一第二抓紧部分；一介于该第一及第二本体部分之间的楔形部分；及/或一调整部分。该第一本体部分可被建构来可滑动地啮合该第二本体部分。该楔形部分可被建构来施加力量于该可滑动地啮合的第一及第二本体部分。该调整部分可被建构来增加或减小该楔形部分施加于该可滑动地啮合的第一及第二本体部分上的力量。当该调整部分增加该楔形部分施加于该可滑动地啮合的第一及第二本体部分上的力量时，介于该第一和第二抓紧部分之间的距离可被减小。; a second body portion that includes a second gripping portion; a wedge portion between the first and second body portions; and/or an adjustment portion. The first body portion may be configured to slidably engage the second body portion. The wedge portion may be configured to exert force on the slidably engaged first and second body portions. The adjustment portion may be configured to increase or decrease the force exerted by the wedge portion on the slidably engaged first and second body portions. When the adjustment portion increases the force exerted by the wedge portion on the slidably engaged first and second body portions, a distance between the first and second gripping portions may decrease.
