Description

one

The invention relates to hydromechanization of earthworks, namely, to a dredger with a crustless panilonage, and can be used for the development of canals and pits, dredging, cleaning of industrial sedimentation tanks, and the extraction of non-metallic building materials.

There are known several types of dredgers with bezel-free papilionage in which the pilotage is carried out, for example, by rotating the entire dredge around the pressure piles.

A dredger with a bezel is not known, containing a floating body, a soil collecting device, cool and pressure piles, a papilionic device movably mounted in longitudinal guides fixed in the body opening, and made in the form of a transverse beam with guides on which the main beam is installed the cart of the additional pressure head pile.

The principle of operation of such a dredger is as follows.

Before the start of papilionage, the dredger will deepen the piles of the pressure stroke and the secondary pressure stroke, and raise the funny pile. A podilioge device is included in the operation, while carrying

the pile of the additional pressure stroke carriage begins to forcibly move along the cross-beam guides in the housing opening, causing the hull of the dredger to turn around the pressure-stroke pile, and the transverse beam moves along the longitudinal guides attached to the body, while the soil collecting device performs a working stroke.

The disadvantages of the described dredger are the complexity and cumbersome papilonazhny device, leading to a significant increase in the size of the dredger.

A famous dredger with a bezel-free papillon is known, which includes a floating hull, a soil collecting device, a papilionaed drive with blocks of tacks mounted on the hull, and the rim and 11 head) first piles.

Primer-mounted device mounted on a turntable mounted in the nose of the corus and having a lever.

A soil removal device is used to turn it around a roundabout circle with the help of winches, cables fixed on the turntable lever, and blocks of pulley blocks. Cool and pressure piles while omitted in 1-runt.

The advantage of this dredger is

Ensuring the bezel-free papilionage of the soil collecting device with the help of a simple system of tackles and winches.

However, in such a dredger, the length of the collecting device is limited, since it depends on the effort of the winch and the length of the lever of the turntable, limited by the dimensions of the standard zemniar and.

The length of the soil-collecting device that is optimal for a given dredger allows the development of slits slightly exceeding the width of the dredger housing. To develop wider slits, the dredger must make several working passes, which requires additional time and generally reduces the productivity of the dredger.

The aim of the invention is not to create a dredger that combines the simplicity of panilonage of a group-collecting device with a higher productivity by increasing the width of the slot and, as a result, reducing the number of working passes.

This goal is achieved by the fact that the well-known dredger with a bezel-free core, including a floating body, a soil collecting device, a papilonazh drive with blocks of polyspasts, cool and pressure piles, is provided with pontoons located on both sides of the body, in the horizontal plane rigidly connected with it, while on the pontoons are installed blocks of tacks.

For the purpose of additional fixing of pontoons, cool piles can be brought out on pontoons.

Moving the podilonazh drive pulley blocks out of the dredger hull allows you to increase the piling heading of the soil collecting device and thus the width of the slot, reducing the number of working passes of the dredge, which significantly increases the productivity of the dredge.

The drawing shows the proposed dredger d, top view.

Zemspar includes a floating hull 1, a soil collecting device 2, a papilonazhny drive 3 containing winch 4 and 5 and tackle consisting of blocks 6-9 and cables 10, 11, cool 12, 13 and pressure head 14 piles.

One pair of blocks 6 and 7 of podilonazhnyh tackles is attached to the hull 1 of the dredger. Another pair of blocks 8 and 9 is installed on pontoons 15 and 16 located on both sides of housing 1 and rigidly connected to it in a horizontal plane, for example, bridges 17 and 18. Cool piles 12 and 13 can be moved to pontoons 15 and 16.

Grounding device 2 is connected to the slurry pipe in the bow of the housing 1

spherical joint 19.

Panilonage of a soil collecting device is manufactured as follows.

When the cable 10 is wound on the drum of the winch 4 through blocks 6 and 8, the soil collecting device 2 turns to the right. At the same time, on the winch 5, the cable 11 is unwound from the drum through the blocks 7 and 9. The movement of the collecting device to the left is carried out in the same way.

Cool 12, 13 and 14 piles at the same time lowered into the ground.
