Conveyer with stretchable and retractable conveying arm

Abstract

The invention provides a conveyer with a stretchable and retractable conveying arm. The conveyer with the stretchable and retractable conveying arm comprises a hull base, a portal frame, a winch and the stretchable and retractable conveying arm. The conveyer with the stretchable and retractable conveying arm is characterized in that steel wire rope lantern rings are arranged on the two sides of the top end of the portal frame, each lantern ring is connected with steel wire rope lifting points on the two sides of the stretchable and retractable conveying arm through fixing steel wire ropes, the stretchable and retractable conveying arm conducts stretching and retracting through a scissor fork hydraulic stretching and retracting mechanism, scissor fork mechanisms are arranged on the two sides of a scissor fork arm rack, hinge joint of each scissor fork mechanism is achieved through steel plates and shafts, one end of a tail fixing device is connected with the scissor fork arm rack and multi-level hydraulic oil cylinders, and the multi-level hydraulic oil cylinders are assembled in an arm rack frame. The conveyer with the stretchable and retractable conveying arm has the characteristic that the conveying arm can be retracted. Besides, when the conveying arm is stretched and retracted, the influence on the balance performance of a hull is little, the dead load of the conveying arm is small, the stretching distance is long, the transmission efficiency is high, and the space occupied by the conveying arm is small after the conveying arm is retracted; the conveyer with the stretchable and retractable conveying arm is stable in work and high in safety; and the conveying angle of the conveyer can be adjusted, and therefore the conveyer with the stretchable and retractable conveying arm is suitable for sand discharge on different working conditions.

Description

technical field [0001] The present invention relates to the technical field of design and manufacture, in particular to a conveyor with retractable conveying arms. Background technique [0002] At present, the conveyors on the domestic water transportation market mainly use the fixed outswing type conveyors. Such conveyors cause the overall working position of the hull to be too long during the transportation process. When encountering wind and waves, the hull is unstable and easy It will cause the transport ship to roll over, and it will take up too much space when passing through the ship lock, which will reduce the efficiency of the ship lock. security risks. In the existing market, there is a scheme of rotating and recycling the conveyor to one side of the sand carrier in a non-working state, but during the rotation and recycling of the conveying arm, due to the different weights of the left and right sides of the hull, it is easy to cause rollover, so this scheme still...
