Abstract

The invention discloses a truss type hydraulic folding and conveying device for ships. The truss type hydraulic folding and conveying device for ships comprises a fixing rack, a belt conveying mechanism and a foldable truss type conveying arm mechanism, wherein the belt conveying mechanism is arranged in the truss type conveying arm mechanism, the truss type conveying arm mechanism comprises a first conveying arm and a second conveying arm, the first conveying arm is connected with the fixing rack in a folding mode, the second conveying arm and the first conveying arm are connected in a folding mode, the fixing rack is provided with a security portal frame and a wire rope winding mechanism, the bottom of the security portal frame is connected to the fixing rack in a rotatable mode, the security portal frame is automatically erected or folded along with unfolding or folding of the first conveying arm, a foldable supporting connection rod is hinged between the lower portion of the security portal frame and the fixing rack, the maximum erecting angle B of the security portal frame is smaller than 90 degrees when the supporting connection rod is completely unfolded, and a wire rope is connected to the front end and the middle of the first conveying arm through an idler wheel at the top of the security portal frame. The truss type hydraulic folding and conveying device for ships has the advantages of being low in cost, high in safety, operability and navigation capacity and low in safety accident rate.

Description

technical field [0001] The invention relates to the technical field of sand unloading conveying devices, in particular to a truss type hydraulic folding conveying device for sand unloading ships. Background technique [0002] At present, the self-unloading ship conveying device for transporting sand and gravel in China is mainly a non-foldable sand-discharging conveying device. The device uses a wire rope hoist to pull a non-foldable sand-discharging conveying arm through a gantry frame, and adjusts the swing angle of the conveying arm to realize the conveying arm and sand-discharging. The location of the points is consistent to adapt to different geographical environment conditions. The conveyor belt is placed on the conveyor frame through the rollers, and the belt conveyor drives the belt to rotate, so as to realize the transportation of the sand and gravel unloaded in the warehouse to the sand unloading point. Since the device cannot be folded, the bow is stretched out a...
