The invention discloses a quick-refit secondary lining trolley which comprises a trolley door frame, a trolley body, a trolley body, a trolley body and a trolley body, the trolley body door frame comprises two vertical supporting rods and a transverse rod connected to the tops of the two vertical supporting rods, and the two vertical supporting rods and the transverse rod are connected into a door shape; the lower parts of the two vertical supporting rods are respectively connected with a supporting seat; the adjusting and supporting structure comprises an adjusting block, a jack and a steel gasket; the jack is erected above the portal frame bottom beam, and the top of the jack abuts against the supporting base. The adjusting block and the steel gasket are movably connected to the upper portion of the portal bottom beam, and when the jack stretches out to lift the trolley portal to the designated height or the maximum height, the adjusting block is moved to the position between the trolley portal and the portal bottom beam; and when the jack extends to the maximum height and does not reach the specified height, and the adjusting block is arranged between the trolley portal and the portal bottom beam, the jack is contracted, and the steel gasket is arranged at the bottom of the jack to increase the height supported by the bottom of the jack. According to the rapidly-modified secondary lining trolley, rapid lifting can be achieved, and the occupied space is small in the modification process.
