The utility model discloses an opposite-pull trolley for mounting a large-diameter PCCP (prestressed concrete cylinder pipe). The device comprises a frame, a stretching cross beam and a fixed cross beam used for being clamped and fixed between adjacent PCCPs. Wherein the fixed cross beam is arranged on the frame, the stretching cross beam is slidably arranged on the frame in a front-back sliding mode, a stretching driving mechanism used for driving the stretching cross beam to slide is arranged on the frame, pull ropes are connected to the two ends of the stretching cross beam, and abutting beams used for abutting against the outer end of a PCCP to be installed are connected to the extending ends of the pull ropes. The opposite-pull trolley for mounting the large-diameter PCCP is convenient to operate, and the mounting quality and the mounting efficiency of the PCCP can be improved. 本实用新型公开了一种大口径PCCP管安装用对拉台车，包括车架、拉伸横梁和用于卡固在相邻PCCP管之间的固定横梁，固定横梁设于车架的上，拉伸横梁能够前后滑动地滑设于车架上，车架上设有用于驱动拉伸横梁滑动的拉伸驱动机构，拉伸横梁的两端均连接有拉绳，拉绳的延伸端
