The invention relates to the technical field of spent fuel dry-process indoor lifting appliances, in particular to a pneumatic switch protection device suitable for a spent fuel dry-process indoor lifting appliance, which comprises a square table. Feet are rotatably connected to four corners of the bottom surface of the square table through limiting hinged supports, grooves are formed in the bottom surfaces of the feet; rubber protection pads are inserted into the grooves; the upper end of the rear wall of the square table is rotationally connected with a protective cover through hinges. The protective cover is made of transparent plastic, so that a switch control rod is protected from being touched by mistake, human errors are reduced, a worker can observe the state of an operating rod anytime and anywhere, and the spent fuel dry process technological process is optimized; the protective cover is connected with the square table in a hinge mode, so that the worker can conveniently open and close the protective cover, the time for operating the switch control rod is shortened, and the potential radiation protection risk existing in equipment is reduced; the integrity of the single-joint pipeline is effectively protected through a wire coil, so that the situation that a worker treads and pulls the single-joint pipeline, and consequently the joint falls off is prevented.

    本发明涉及乏燃料干法室内吊具技术领域,具体涉及一种适用于乏燃料干法室内吊具气动开关保护装置,包括方台,方台底面四角处均通过限位铰座转动连接有地脚,地脚底面开设有凹槽,凹槽内部插接有橡胶保护垫,方台后壁上端通过铰链转动连接有保护罩。本发明的防护罩采用透明塑料制作,一方面保护了开关控制杆不被误触,减少了人因失误,另一方面使得工作人员可随时随地观察操作杆状态,优化了乏燃料干法工艺流程,保护罩采用铰链形式与方台相连,方便人员开关保护罩,减少了操作开关控制杆的时间,减少了设备存在的潜在辐射防护风险,线盘有效的保护了单接头管线的完整性,防止工作人员踩踏、拉扯单接头管线导致接头脱落。
