摘要（英）：

The utility model discloses an instrument for detecting concrete crushing strength of an in-service electric pole. The instrument comprises a fixing device, a control device and a force application device. The fixing device comprises threaded rods, rod heads, nuts and fixing tables. The control device comprises a displacement sensor, a pressure sensor, and an operating panel. The force application device comprises a hydraulic cylinder and a spherical pressing head. The number of the fixing tables is two, and the two fixing tables are placed on the two sides of the electric pole. The number of the threaded rods is two, the top ends of the threaded rods are fixed with the rod heads, and the two threaded rods respectively penetrate through the two sides of the two fixing tables to be fixed on the fixing tables through the nuts. The central line of one fixing table penetrates through the hydraulic cylinder, and the spherical pressing head is connected with the inner side of the hydraulic cylinder to make contact with the electric pole. The displacement sensor and the pressure sensor are fixed between the hydraulic cylinder and the spherical pressing head, and the operating panel is connected with the output end of the hydraulic cylinder. The instrument is high in measurement accuracy and small in error, saves time and labor, and improves work efficiency.
