Needle beam trolley

The invention discloses a needle beam trolley. The trolley travels along the needle beam; the needle beam comprises a plurality of sections of needle beam units which are detachably connected; the trolley comprises a plurality of sections of trolley units. And during linear section construction, the needle beam unit and the trolley unit are assembled into a whole for lining construction. When the arc section is constructed, the trolley is split into mutually independent units, and the trolley units walk to the needle beam units; each section of needle beam unit is detached, and the redundant needle beam units are transported out; lining construction is conducted through the front-end needle beam unit and the trolley unit on the front-end needle beam unit; demolding after construction is completed; and the assembly of each needle beam unit and the trolley unit is independently bent. And each trolley unit is designed to comprise a plurality of side mold assemblies so as to improve the clearance after mold remov
