SU1229280A1 - Cable-laying machine - Google Patents

Description

The invention relates to earthmoving machines, namely, cable laying with blade tools.

The aim of the invention is to improve the reliability of the cable conductor,

Figure 1 shows the cable layer when laying the cable in the ground; FIG. 2 is the same when removing the cable from the ground; on fig.Z - block of laying and removing knives,

The cable layer contains a base cable 1, a cable 2 unwinding mechanism 3 an electronic system 4 automatically tracking the cable and a semi-trailer 5 with laying 6 and removing 7 knives mounted on axis 8, Laying and removing knives are made in one block 9 with a reciprocal opposite direction. At block 9 there is a proppin 10 near the center of gravity of block 9, designed to install the latter on the axis 8 of the knives, which is located in the longitudinal vertical plane 11 of symmetry of the semi-trailer. On the semi-trailer 5 there is installed a hydraulic piston 12 for deepening the knife 6 or 7. The guide cassette 13 is mounted on the knives, and voltage regulator 14 and sensors 15 and 16 are respectively installed on the base station of gauge 1 and retrieval knife 7, respectively.

For laying the cable 3 into the ground (Fig. 1), the blade unit 9 is manually rotated around the axis 8 so that the laying knife 6 is at the bottom. The stroke of the base drum 1 and the hydraulic cylinder 12 are turned on and the knife 6 is sunk into the ground. At the same time, the cable 3 is unwound from the drum of the unwinding mechanism 2 and goes to the ground through the guide cassette 13 connected to the knife

To remove the cable 3 from the soil (Fig 2), the blade unit 9 is rotated around the axis 8 so that the removal knife 7 is at the bottom. The end of the cable 3 removed from the ground through the guide cassette 13 and the voltage regulator roller 14 is fixed to the drum of the winding mechanism 2 of the cable 3, include the stroke of the base rod 1, the electronic system 4 automatically tracks the cable 3 in the ground and the hydraulic cylinder 12 knife 7 is buried in the ground. The knife cuts the soil over the cable 3 ,. and the cable retrieved from the ground is wound on the drum of the winding mechanism 2. The search for cable in the ground and the strict following of the machine along its route is provided automatically by an electronic system 4 with sensors 15 and 16,

Upon completion, the block 9 knives turn on the axis 8 in a horizontal position and fixed.
