The hull rib installation detecting device comprises an elongated rail, a screw rod, a mounting seat, a detector base, a detector, a measuring instrument including a connecting arm and a measuring head at the end of the connecting arm, and the measuring head is a laser sensor measuring head; The utility model comprises: locating a hull rib to be installed on the hull skeleton, the slideway is placed along the rib of the hull, and the laser sensor of the measuring head of the detector reads the reference data as initial data, and then starts driving the motor, and the screw drives the detector along The hull rib moves, and the laser sensor of the detector head moves from one end of the hull to the other end to read the data.
The lateral reinforcement of the aluminum hull ribs, generally T-shaped, is usually located on the entire rib to prevent the ship's side outer panel from being unstable and deformed.
Reasonable welding sequence for aluminum hull ribs
When welding aluminum alloy hulls, reference can be made to the welding sequence of steel ships. Generally speaking:
1 First weld the middle part of the hull, then gradually spread the welding on both sides.
2 First weld the longitudinal section of the ship and then gradually weld it symmetrically to both sides.
3 The longitudinal members are welded first and then welded in the transverse members. This method can be used as a support point by the characteristics of the longitudinal structure to reduce the welding deformation of the aluminum alloy.
