Abstract

The invention relates to construction equipment and can be used when laying underground pipelines. The purpose of the invention is to reduce energy consumption for laying pipes. The pipe laying device contains an advanced cutting body 1, which is connected via hydraulic cylinders 3 to tamping plate 4. A drill 8 is mounted and can be rotated and moved on a horizontal shaft 7, and the ring bore 12 is rigidly fixed. Anchor 12 has a hydraulic power cylinder 13, on which rod is mounted hydraulic clamps 14. When working the soil with a leading cutting body 1, the soil is laid in the upper part of the trench by means of a transporting mechanism. At the same time, the drill 8 selects in the slot walls two segmental cavities into which the laid pipe is drawn. 2 hp ff, 5 ill.

The invention relates to construction equipment and can be used when laying underground pipelines.

The purpose of the invention is to reduce energy consumption for laying pipes.

Figure 1 shows the device, a longitudinal section; figure 2 is the same, top view; in FIG. 3, section A-A in FIG. one; figure 4 - section bb in figure 1; figure 5 - section bb In figure 1.

The pipe laying device comprises a leading cutting member 1 mounted on frame 2, two hydraulic cylinders 3 which connect the cutting member 1 to the tamping plate 4 having a body 5 and a wall 6.

On the horizontal shaft 7, the drill 8 is mounted with the possibility of rotation and movement along the shaft 7 with the drive 9, which is connected to the hydraulic cylinder 11 of the movement of the drill with the help of the clamp 10. On the shaft 7, ring measles 12 are rigidly fixed.

Ring measles 12 has a power cylinder 13, on the rod of which hydraulic claws 14 are mounted.

On the upper part of the housing 5 of the leading cutting member 1, a twin screw transporting mechanism 15 with a loading unit 16 and a common drive 17 is mounted at one end, and the other end of the transporting mechanism 15 rests on the tamping plate 4 slidably on its upper side.

The wall 6 of the tamping plate 4 is made with the possibility of vertical movement by means of a hydraulic cylinder 18.

On the housing 5, one end of the upper valve 19 is rigidly fixed, located above the drill 8.

The lower valve 20, kinematically connected with the drill 8, is independently driven to move in the form of a hydraulic cylinder 21. The device is equipped with a pumping station 22, hydraulic actuators 23, control system 24.

The device works as follows.

Turning on the actuator 17, the vertical leading cutting member 1 and the horizontal transport mechanism 15 are rotated through the gearboxes. In this case, the hydraulic cylinders 3 are pressurized into the extra piston cavity and, due to extension of the rods, the frame 2 moves along the pipeline axis. The destroyed soil is laid in a trench over the drill 8. The upper valve 19 prevents the penetration of the soil to the drill 8 and into the underlying part of the trench. Together with turning on the drive 17, the drive 9 turns on the drill 8. By means of the hydraulic cylinder 11 the drill 8 moves along the shaft 7 in a kinematic connection with

lower valve 20, which serves as a guide for the drill 8.

During the forward movement, the drill 8 selects two segment cavities in the slot walls. Designed primer while under

By the action of its own weight it wakes up in the lower part of the slot. When approaching the wall 6, the drill 8, for example, stops the movement with the help of a limit switch and switches on the oil supply to the overhead piston.

5 cavity of the hydraulic cylinder 21, which presses the lower valve 20 against the wall 6 until it stops. The oil supply to the hydraulic cylinders 3 is turned on. At the same time, the plate 4 is retracted and compacts the developed soil, located above and below the segment cavities.

At the same time, pressure is applied to the sub-piston cavity of the hydraulic cylinder 13 and the pipe gripped by hydraulic grips 14. It is 5 5 tons that is formed into the resulting cavity.

The resistance to friction and the mass of the pipe affect the annular bark 12 and the tamping plate 4, which compresses the destroyed soil. The wall 6 of the plate 4 squeezes the drill 8 and the valve 20 back to distance. the magnitude of the compaction of the soil due to the rotation of the bracket 10 and the movement of the rod of the hydraulic cylinder 21.

After soil compaction is removed

5 pressure in the cylinders 3 and 13. The work includes the cylinders 18, which move the wall 6 up and down.

By this movement, the wall 6 is freed from adhering soil. Subspecies

0 pressure in the piston cavities of the hydraulic cylinders 3, the tamping plate 4 is retracted from the compacted soil to the leading cutting member 1, which again performs the development of the soil. With the help of a torsion valve of the porting mechanism 15, the soil is placed in the upper cavity of the slot between wall 6 and the previously compacted soil mass,

The cycle of operation is repeated.
