The utility model discloses an auxiliary moving device for a steel arch frame. The steel arch auxiliary moving device comprises a steel arch auxiliary moving device body, a steel arch auxiliary movingdevice working body is arranged at one end of the steel arch auxiliary moving device body in an extending mode, the whole steel arch auxiliary moving device working body is a steel plate-shaped bodycomponent, and a plurality of steel arch clamping grooves are formed in the plate-shaped body component; And a steel arch frame auxiliary moving device operating body is arranged at the other end of the steel arch frame auxiliary moving device body in an extending manner. The device is simple in design structure; Novel structure, manpower can be saved by utilizing the lever principle; Working timeis shortened, and transportation efficiency is improved, the steel arch frame can be moved by one person; The labor cost is saved while the labor intensity of operators is reduced, and meanwhile, thetechnical problem that when I-shaped steel is not long enough sometimes and needs to be welded, welding needs to be aligned, so that the I-shaped steel is tidier and convenient to weld during welding, and a welded connector is very attractive is solved.
