Operation vehicle for mounting tunnel arch trusses

The utility model discloses an operation vehicle for mounting tunnel arch trusses. The operation vehicle comprises a frame, a traveling mechanism, a traction mechanism, an arch truss lifter and an arch truss conveying mechanism, wherein the arch truss lifter is positioned at the rear part of the frame, and used for lifting the arch trusses needed to be mounted one by one; the arch truss conveying mechanism is used for conveying the lifted arch trusses one by one to design and mounting positions via contraposition adjustment; the arch truss conveying mechanism comprises a translation trolley capable of moving front and back at the upper part of the frame, a lifting mechanism for stably lifting the tunnel arch trusses, and a horizontal motion mechanism for driving the lifting mechanism to horizontally move; and the translation trolley, the horizontal motion mechanism and the lifting mechanism can respectively adjust the tunnel arch trusses in the directions such as front and back, left and right, and up and down. The operation vehicle provided by the utility model has reasonable design, convenience in assembly, simplicity in operation, safety and reliability in work property and good use effect, and can solve the problems in the conventional steel arch truss mounting that after being lifted, the steel arch trusses have difficulty in movement and positioning, low mounting efficiency, large labor intensity and the like.
