[0024] like Figure 1 As shown, the utility model provides a secondary lining trolley for a small-section oil pipe tunnel, comprising:

[0025] A base plate 1, which is laid on the tunnel floor;

[0026] Two running rails 2 are laid parallel to each other on the base plate 1;

[0027] The vertical poles 3 have two rows and are respectively arranged vertically on the travel track 2 through the lifting cylinders 4 and are located on both sides of the bottom plate 1. The bottom of the lifting cylinders 4 is provided with travel wheels through the base;

[0028] A first crossbeam 5, which is transversely mounted on the top of the vertical pole 3;

[0029] A second crossbeam 6 is horizontally arranged on the first crossbeam 5 through a longitudinal rod 9; both ends of the second crossbeam 6 are against a top mold 7; side molds 8 are arranged on both sides of the top mold 7, and the two side molds 8 and the top mold 7 form a tunnel shape;

[0030] Among them, in this embodiment, the base plate 1, the vertical pole 3, the lifting cylinder 4, the first cross beam 5, the second cross beam 6, the top mold and the side surface constitute the main structure of the second lining trolley of the present application, and the structure is stable.
