Container bottom cross beam line drawing equipment

The utility model belongs to the technical field of containers, and particularly relates to container bottom cross beam line drawing equipment. The line drawing device is used for drawing a line on a first bottom cross beam at the front end of a container underframe, can guarantee the line drawing stability of a bottom cross beam reinforcing plate, and eliminates potential safety hazards generated when personnel carry the bottom cross beam. Comprising a bottom plate, a lifting cylinder for lifting is arranged at the bottom of the bottom plate, and a line drawing mechanism is arranged at the top of the bottom plate; the line drawing mechanism comprises a fixing plate, and a linear guide rail and a ball screw are installed on the fixing plate. The two ends of the ball screw are fixed to the fixing plate through a screw fixing base, and the ball screw can freely rotate relative to the screw fixing base. The ball screw is driven by a servo motor to rotate; the ball screw is in transmission connection with the nut
