一种悬挑滑移桁架卸载装置
摘要：
本实用新型公开了一种悬挑滑移桁架卸载装置，解决了现有桁架卸载施工操作繁琐且不能一次安装到位的技术问题。本实用新型设置在桁架与支撑平台之间，包括与桁架相顶接的一组千斤顶，两个千斤顶之间设置有分级抽取的垫板，所述桁架的下弦架连接有竖直的立柱，立柱的两侧设置有卸载牛腿，所述千斤顶设置在卸载牛腿和支撑平台之间，千斤顶的最低高度小于卸载牛腿与支撑平台之间的距离，所述垫板设置在立柱底面与支撑平台之间。本实用新型在桁架上设置立柱作为永久支撑结构，在立柱的两侧设置卸载牛腿，使用千斤顶对立柱逐级下放实现卸载，避免了临时支撑架及操作平台的搭设和拆除操作，实现了桁架一次安装就位。
摘要（英）：

The utility model discloses a cantilever sliding truss unloading device which solves the technical problems that existing truss unloading construction is complex in operation and cannot be installed in place at a time. The device is arranged between a truss and a supporting platform; the device comprises a group of jacks propped against a truss, a base plate for graded extraction is arranged between the two jacks; a lower chord of the truss is connected with a vertical stand column, unloading brackets are arranged on the two sides of the stand column, the jack is arranged between the unloadingbrackets and the supporting platform, the lowest height of the jack is smaller than the distance between the unloading brackets and the supporting platform, and the base plate is arranged between thebottom face of the stand column and the supporting platform. The stand column is arranged on the truss to serve as a permanent supporting structure, the unloading brackets are arranged on the two sides of the stand column, the stand column is lowered step by step through the jack to achieve unloading, erecting and detaching operation of a temporary supporting frame and an operation platform is avoided, and the truss is installed in place at a time.
