Abstract

The invention relates to the hydromechanization of earthworks. The goal is to improve the redistribution of wave and workloads. The dredger includes a soil-attachment device 2 attached to the hull (K) 1 and suspended on the boom 3. The boom 3 is pivotally connected to K 1 and rests on the bed 4 of the portal 5 connecting the pontoons (P) 6. The bed 4 is located between the lugs fixed in the upper part of the boom 3. In addition to K 1, the boom 3 is connected by a pull 7, the length of which is adjusted by the thaler 8. When shortening the pull 7, the upper portion of the boom 3 rises and the draft 6 decreases. unloaded, as part of the load through the boom 3 is transmitted to K 1. When lengthening the stretch 7, the load on K I decreases, and on P 6 it increases. The ability to regulate the load on the P 6 by redistributing it between them and K 1 expands the field of application of the dredge at the depth of development, increases the efficiency and safety of work. 3 il. e (L 1 / zL 1 / ig 1

Description

The invention relates to hydromechanization of earthworks, namely, to suction dredgers with an increased development depth.

The aim of the invention is to improve the redistribution of wave and workloads.

Figure 1 shows the dredger d, side view; figure 2 - section aa in figure 1; in FIG. 3, the upper part of the portal and the boom on a larger scale.

The dredge consists of a housing 1, on which a ground intake device 2 is hinged. The suspension of the soil intake device 2 is carried out on a boom 3, hinged with its base to the housing 1 and resting its upper part on the bed A of portal 5. Portal 5 st The two pontoons 6 located on both sides of the soil pick-up device 2 are connected to a single design. The boom 3 is fixed to the body 1 with a strap 7, the length of which is adjusted by the lanyard 8. There are stops 9 on the upper part of the boom on both sides of the bed A.

During the installation and operation of the dredger, the load on the pontoons 6 is adjusted by shortening or lengthening the pull 7 with a lanyard 8. When shortening the pull 7, the upper part of the boom 3 rises, the draft of the pontoons 6 is reduced. A redistribution of the load occurs, an additional part of it through the boom 3 and the delay 7 is transferred to the housing 1,

at the same time, the pontoons 6 are unloaded.

When lengthening the stretch 7, the load on the hull I decreases, on the pontoons 6 it increases.

The ability to regulate and reduce the load on the pontoons by improving its redistribution between the pontoons and the hull allows you to expand the field of application of the dredge in the depth of development, to increase the efficiency and safety of work.

Claims (1)

Invention Formula A dredging projectile, comprising a housing with a soil collecting device hinged to it, suspended from an arrow connected to the housing by means of a hinge and resting on pontoons placed on both sides of the soil collecting device and connected to each other by a portal, characterized in that in order to improve the redistribution of wave and workloads, the boom in the upper part is provided with stops and is additionally connected to the body by means of a length adjustable, and the portal has a lodgement installed between the stops, At this point, the arrow is loosely laid on the lodgement. 2 fpus.3 Editor G.
