Abstract

The invention relates to the technical field of the ship engineering, in particular to a movable pile type positioning device of an engineering ship, which is characterized in that: the top part and the lower part of a positioning pile or a shifting pile are respectively provided with an upper pulley block and a lower pulley block, one end of a steel cable connecting the upper pulley block and the lower pulley block in a winding way is connected with a winch support, the other end of the steel cable is connected with a winch drum; one side of a steel column slide component with the shifting pile is provided with a hydraulic cylinder, pin holes at both ends of the hydraulic cylinder are respectively connected with pin shafts arranged on a hull deck and the winch support, a hinge shaft is arranged in the steel column slide component, and the shifting pile can rotate and tilt around the hinge shaft along with the flexion of the hydraulic cylinder. At least two steel column slide components are used, and at least one steel column slide component is provided with the shifting pile. The invention has the beneficial effects that: the positioning pile and the shifting pile are alternately plugged and pulled, the positioning is convenient and accurate, the shifting is rapid and arbitrary, the resistance of the engineering ship against the interference of outside wind and waves is high, no oscillation or swinging can occur in the positioning point, the safety is strong, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to a pile-type positioning device capable of moving back and forth, left and right, for an engineering ship. Background technique [0002] There are many types of engineering ships, such as drilling and blasting ships, harbors, river dredging ships, drilling ships, exploration and harvesting ships, piling ships, and water engineering operation platforms, etc. During the operation, there are problems of positioning and displacement of the ship. [0003] Anchor positioning method, that is, using ropes or iron chains to connect with the iron anchor placed on the outside of the ship. Anchor positioning occupies a large amount of water in the channel, and the extension ropes or chains often connected to the anchor may affect other ships passing in the channel; factors such as the position and number of anchors, wind direction, and water flow may affect the correct positioning o...
