Abstract

The invention relates to the mining and construction industry, in particular to devices for trenchless laying of underground utilities. The goal is to increase productivity and operational reliability. A device for the development and transportation of soil includes a pipeline (TP), inside which is placed the glass core generator. In the chute part of the latter, there are running rollers and a rock picker in the form of a cone-shaped plate. At the bottom part, the fixation mechanism 13 is mounted with stoppers 14 made with self-braking bevels. By means of the stub roller chain 15, the stoppers 14 through the deflecting rollers 16 are hingedly connected to the tiller-block transport mechanism. It is made with a cross-beam 17 attached to a longitudinal bar 18, to which the block 19 is attached. A glass core generator is fed to the face. The breed picker cleans the trough part of the TP from the showered soil. The stoppers 14 collide against the stops 5, the springs of the fixation mechanism 13 are compressed and, after the passage of the stops 5, unclench, ensuring the fixation of the cup core in the head part of the TP. The forces when pushing the TP perceive the stops 5. Upon completion of the TP pushing by the tension of the working cable 20 stored through the block 19, the fixation of the core-filled glass filled with the rock is performed. 3 il.

The invention relates to the mining and construction industry, in particular to devices for trenchless laying of underground utilities.

The purpose of the invention is to increase productivity and operational reliability.

FIG. 1 schematically shows the proposed device in the laid pipeline; in fig. 2 is a view A of FIG. one; in fig. 3 shows the node I in FIG. 2

The device for the development and transportation of soil includes a pipeline 1, equipped with a reinforcing knife 2, a pinch mechanism 3, a deflecting unit 4 and stops 5 attached to its inner surface. Inside the pipeline 1 there is a stacking core 6, made in the form of a shell, in the tray part of which are running rollers 1 7 and 8, pick-up 9 of the breed in the form of a cone-shaped plate, and the upper part has a longitudinal notch 10 in which screw clamps 11 are placed and 12, on the bottom part, a fixation mechanism 13 is mounted with stoppers 14, made with self-braking bevels, which by means of stub-roller chains 15, through deflecting rollers 16, are hingedly connected to a cable-carrying transport mechanism crosshead 17 mounted on a longitudinal bar 18, to which the block 19 is hingedly attached to unscrew and remove the core-former 6 from the bottom of the working

cable 20.

Glass core 6 through the node of the deflecting unit 4 through the cable serves on the face. At the same time, the pick-up of the 9 pods cleans the trough part of the pipeline from showered soil. The stoppers 14 collide against the stops 5, the springs of the fixation mechanism 13 are compressed and, after the passage of the stops 5, they open, ensuring the fixation of the cup-core-shaped generator 6 in the head part of the pipeline 1. Then using a push cylinder (not shown) pushes the pipeline. The forces arising from the pipeline pushing perceive the stops 5.

At the same time, when the pipeline is pushed through, the elastic forces of rock resistance act on the bottom part of the stacking core 6, and through it on the fixation mechanism 13, creating considerable forces on the contact surfaces of the stoppers 14 and stops 5. The breed coming in. the pipeline, before it enters the stacking core 6, is narrowed in cross section by means of a pinching mechanism 3.

Upon completion of the pipeline being pushed by the tension of the working cable 20, stocked through block 19, the deflection is made and then the core-filling glass filled with rock is separated from the rock mass. To reduce the force of unlocking the cup-core former, the rear surfaces of the stoppers 14 and the front surfaces of the stops 5 in the place of contact are made with a self-motor 515

mowing bevels (having, for example, an angle of up to 6) intended for hold, core-core 6 at the head of the pipeline when punching and at the same time, to further facilitate the core-6 unlock when the core is peeled off.

After the core is cut off, the core former 6 is moved to the free end of the pipeline and lifted to the surface. The screw core 6 is then expanded in diameter by means of screw bolts 11 and 12 in the knife and middle parts, which facilitates its subsequent emptying.

Upon completion of all these operations, the cycle is repeated ..
