The invention discloses a tool vehicle for substation operation and maintenance. The tool trolley comprises a tool vehicle body, wherein a square inserting groove is formed in the rear side of the topof the tool vehicle body, a fixing mechanism is arranged on the rear side of the tool vehicle body, a square inserting block is inserted into the square inserting groove, detection equipment is fixedly mounted at the top of the square inserting block, and an access hole is formed in the right side of the tool vehicle body. By arranging the tool vehicle body, the square inserting groove, the fixing mechanism, a threaded through hole, a threaded rod, a rotating handle, the square inserting block, the detection equipment, the access hole, a fixing groove, an access door, the square groove, a clamping mechanism, a positioning block, a positioning rod, a fixing block, an extrusion spring, a connecting block, a pushing handle, a protection block, a circular matching hole, a square through hole,a limiting groove, a limiting block and a pulling groove matched in use, the problem that an existing tool vehicle is poor in detection effect. The tool vehicle for substation operation and maintenance has an advantage of being good in detection effect and is suitable for a substation.
