本文介绍了一种新的救援工具的开发，该工具用于营救因大规模自然灾害而被埋在倒塌建筑废墟中的幸存者。由于大型自然灾害发生后，公共能源供应以及重灾区经常被切断，因此提出了一种由金属氢化物(MH)提供动力的新救援工具。该工具仅利用热能就可以实现很大的升力；此外，它对于进入受限空间和救援非常有效，不需要电力或燃料。设计和实验生产的起重工具包括一个坚固的可伸缩圆筒，每0.1兆帕的内压具有50 mm的举升行程和6500 N的举升输出力，一个密闭的MH容器和一个使用氧化钙的便携式热源。作为压力源的MH的组成是LaNi4.3Co0.5Mn0.2，它在40℃略微解吸氢气，在80℃时具有0.2-0.3 Mpa的平衡压力。MH源封闭在一个坚固的密闭容器中，通过与容器底表面接触的热源来加热MH。当用200克和300克氧化钙加热MH时，两种情况下的MH温度在48秒后都达到了70°C以上。这一反应在氢气压力为10000 17兆帕的情况下，在伸缩气缸中产生了10000 N的升力。300克的氧化钙反应产生了超过75°C的氢气温度，并允许从加热开始起持续放氢超过5分钟。据估计，使用这种机构的起重工具、MH成分以及在75°C下较高的平衡压力将提供更高的输出力。此外，在较低温度下发生氢脱附的起重工具将为举升操作提供更快的响应时间。
This paper addresses the development of a new rescue tool for saving survivors buried in the debris of a collapsed building caused by a large-scale natural disaster. Because access to the public energy supplies as well as the seriously stricken area are frequently cut off just after the occurrence of a large natural disaster, a new rescue tool powered by metal hydride (MH) is being proposed. The tool achieves a large lifting force solely utilizing thermal energy; in addition, it is effective for confined space entry and rescues without the need for electricity or fuel. The lifting tool that was designed and experimentally produced was comprised a robust telescopic cylinder having 50 mm of lifting stroke and 6500 N of lifting output force per 0.1 MPa of internal pressure, an airtight MH container, and a portable heat source employing calcium oxide. The composition of MH as the pressure source was LaNi4.3Co0.5Mn0.2, which slightly desorbed hydrogen at 40°C and possessed 0.2–0.3 MPa of equilibrium pressure at 80°C. The MH source was enclosed within a solidly constructed airtight container that heated the MH via a heat source in contact with the bottom surface of the container. When the MH was heated using 200 and 300 g of calcium oxide; the MH temperatures in both the cases reached in excess of 70°C after 48 seconds. This reaction created a lifting force of 10000 N in the telescopic cylinder for hydrogen pressures of 0.17 MPa. The 300 g of calcium oxide reaction created MH temperatures in excess of 75°C and allowed for constant hydrogen desorption for over five minutes from the start of heating. It is estimated that the lifting tool utilizing this mechanism, MH compositions, and a higher equilibrium pressure at 75°C will provide a higher output force. In addition, a lifting tool where the initiation of hydrogen desorption occurs at lower temperatures will provide a faster response time for the lifting operation.
