Description

I., ol) ete1-1ie refers to the .ie.-vLicjiornOMy mechanical engineering, namely to the devices used in the construction of trunk pipelines in an oblique way.

A working body of the earthmoving machine is known, which includes rotors mounted on the frame along the sides of the pipeline in a plane perpendicular to its longitudinal axis, and having the ability to install iodine at an angle to each other by means of a hydraulic cylinder 1.

However, this working body is not characterized by high productivity. In addition, it requires additional costs for the preparation of roads on both sides of pipelines.

Closest to the proposed facility is a device for removing soil from under the pipeline, including a driving tool mounted on the frame, a coaxially mounted thrower and support rollers in contact with the pipeline 2.

However, the known device is cumbersome, difficult to operate, since it is impossible to remove it from the pipeline without dismantling and, at the same time, the volume of the developed soil exceeds the trench required by the floor pipeline.

The purpose of the invention is to reduce the labor intensity by eliminating the dismantling of the device and reducing the volume of earthworks.

The goal is achieved by the fact that in the device for removing soil from under the pipeline, including a driving tool mounted on the frame, a coaxially mounted thrower and support rollers in contact with the pipeline, the frame is equipped with hinged brackets with additional support rollers and control cylinders. , the rods of which are hingedly connected with the crowns, and the housings - with the frame, while the longitudinal axis of the working body is located under the longitudinal axis of the pipeline.

FIG. 1 shows the proposed device (rear view), a general view; in fig. 2 - the same, top view; in fig. 3 - the working body of the device under the pipeline, a general view.

The device for removing soil from under the pipeline consists of a frame i connected to the base machine, a working body 2 placed on frame 1 and made of conical ripper 3 mounted on one shaft, rotor 4 and thrower 5. Between the rotor 4 and the thrower 5 is installed casing 6 guiding the ground. The actuator 7 is driven from a driving gear through a system of cardan shafts, gears and a planetary gearbox.

Frame 1 houses support rollers 8 and additional support rollers 9 mounted on brackets 10, which are hingedly connected to frame 1 and controlled by hydraulic cylinders 11, the shafts of which are hingedly connected to brackets 10, and

- housing - with frame 1. The longitudinal axis of the working body 1 is located under the longitudinal axis of the pipeline 12.

The device works as follows.

From the base machine, with the help of cardan shafts, gears and a planetary gearbox, torque is transmitted to the working body 2 with a conical ripper 3 on it, which serves to set the direction of movement and soil loosening. The soil developed by the working body 2 is guided by the casing 6 to the loading into the thrower 5. The thrower 5 also receives the drive from the planetary gearbox, but with a correspondingly much higher speed. Thrower 5, made of a ring and elastic and configured to the desired range and accuracy of the throwing, evacuates the soil from under the pipeline in accordance with a given mode of operation. Pipeline under the action of its

The weight quietly sinks to the bottom of the dug trenches.

In order to avoid deviation of the development of the trench: ei, additional support rollers 5 are fixed in the direction of movement on the front of the base machine frame, which descend onto the pipeline with the help of hydraulic cylinders 11 and prevent the development of the trench to deviate to the right in the direction of movement. The support rollers 8 prevent the pipeline from deviating in the other direction. When transporting, additional support rollers 9 by means of hydraulic cylinders 11 prevent the development of the trench to the right in the direction of movement. Rollers 8 prevent deflection in the other direction. When transporting, the rollers 9 are raised to the vertical position by means of the brackets 10.

The proposed method for laying pipelines is one of the technological schemes for lifting pipe without wires.

The use of the proposed device allows reducing the laboriousness of the work and the volume of earthworks.
