Abstract

Use: subsea development of soils. SUMMARY OF THE INVENTION: The suction dredger comprises a floating body 1 and pressure piles 4 with hydraulic cylinders 11 moving them in a vertical plane. Each pressure head 4 is made of sections 6 pivotally interconnected. 7. The upper section 6 is pivotally connected to the floating body 1. The bottom section 7 is made telescopic. The hydraulic cylinders 11 are hinged on sections 6, 7. The floating body 1 is fed to the face at once by two pressure piles 4 when they are compressed by hydraulic cylinders 11. Then one pressure pile 4 is lifted and papilated. 4 il.

Description

Fig, 1

The invention relates to the hydromechanization of earthworks, namely to the suction dredger.

The purpose of the invention is to simplify the design of the suction dredge and increase maneuverability.

FIG. 1 shows a dredger, side view; in fig. 2 - the same. view from above; in fig. 3 is a view A of FIG. one; in fig. 4 is a section BB in FIG. one.

The suction dredger includes a floating body 1 with an opening, a soil collecting frame 2 with a frame-lifting mechanism 3 and pressure piles 4 with hydraulic cylinders 5 moving them in a horizontal plane, mounted along the sides of the floating body 1. Each pressure pile 4 is made of sections hinged between each other: the upper 6 and lower 7. The upper section 6 is pivotally fixed on the bracket 8 of the housing 1 with the possibility of its rotation in a vertical plane by means of a hydraulic cylinder 9 pivotally fixed between them. The lower section 7 is made telescopic with the possibility of fixing it along the length, for example, by means of adjustable stoppers 10 inserted into the through-holes of the assemblies of section 7. At the same time, the hydraulic cylinders 11 displacing the pressure piles 4 are hinged on their adjacent sections 6 and 7, Zemsnar it is also equipped with a cool pile 12 with a mechanism 13 for raising and lowering it. At the lower end of the frame 2, the stop 14 is installed with a spherical working surface.

Suction dredge works as follows.

Housing 1 dredger yes installed

at an angle of 2 to the axis of the drill, pile 4, located further from the axis of the slot, is pierced into the bottom with its tip, with the help of the hydraulic cylinder 9 (with a booster) the cool pile 12 is also pierced into the bottom, another pressure head pile 4 remains uncovered into the bottom (its upper section 6 parallel DP). The frame 2 is lowered to the bottom, the grouser begins, the dredger is deployed

relative to the axis of the slot at an angle a around the axis of the cool pile 12 by acting on the hydraulic cylinder 5 on the upper section 6, turning it at an angle a (in plan, the hydraulic cylinder

9 is fixed in the position when the pile 4 is stabbed into the bottom), as well as the shrinking, approaching (reducing the angle ft) sections b and 7 to each other by the hydraulic cylinder 11. At the end of the turn of the other, the pile 4 is punctured into the bottom by the hydraulic cylinder 9, the frame 2 is supported the bottom is an abutment 14. the working shaft 4 rises, returns to the initial position (section 6 is parallel to the DP. The angle is the same), and stabs to the bottom;

on the face, by the value of S, immediately by two of their 4 by squeezing (approaching) them with hydraulic cylinders 11 (pile 12 is preliminarily raised). Next, the pile is lifted by 4 hydraulic cylinder 9, a barrette at the bottom of the cool pile 12, and the housing of the 1 dredger is turned at an angle a with a bottom fence using a pressure pile 4 located farther from the slot axis. The cycle continues.
