Surface deformation detection device for special equipment

The invention provides a surface deformation detection device for special equipment. The device comprises an ejection unit and a guide unit, the ejection unit is a bin body, mounting grooves distributed in a central symmetry mode are formed in the bin body in a penetrating mode, telescopic probes are embedded in the mounting grooves, limiting channels distributed in a central symmetry mode are formed in the guide unit, the limiting channels correspond to the mounting grooves in a one-to-one mode, elastic assemblies are arranged at the tail ends of the telescopic probes, and the head ends of the telescopic probes can extend out of the mounting grooves and extend into the limiting channels; and a displacement sensor is arranged in each limiting channel. The device has the advantages of simplicity and convenience in operation, high measurement precision and capability of realizing quantitative detection. 本发明提供用于特种设备的表面变形检测装置，包括弹射单元和导向单元，弹射单元为一仓体，仓体内贯通设置呈中心对称分布的安装槽，安装槽内嵌设伸缩探针，导向单元内置呈中心对称分布的限位通道，限位通道与所述安装槽的分布一一对应，
