Abstract

The invention relates to hydraulic engineering, in particular to devices for towing pavers when facing concrete channels. The purpose of the invention is to increase the reliability of work and reduce material consumption. An arrow 4 is attached to the rear of the self-propelled frame 1 with a 2-wheel drive and a traction winch 3 with an anchor 5 on which the blocks 7 are mounted. A cable 10 of the winch 3 connected to the paver I. is attached to the anchor 5 drive 9 supporting wheel 8. Anchor 5 has a tooth 6. Before the start of concreting, cut the surface of the channel, place the device and the paver 11 in the channel and connect them with the cable 10. Turn on the drive 2 and move the device to the first load. Raise the wheel 8 driven 9, lowering the anchor 5 in when WET. Turn winch 3 on by moving the paver along the channel and revealing the concrete with it. After approaching the paver to the device, the winch 3 is turned off, and the drive 2 is turned on, having previously removed the anchor 5 from the ground with the drive 9. When the device is moved, the cable 10 is unwound from the winch 3. 3 sludge. ksh lanra

The invention relates to hydraulic construction, and more specifically to devices for towing concrete pavers in the construction of monolithic anti-seepage irrigation canals.

The purpose of the invention is to increase the reliability of work and reduce material consumption.

FIG. 1 shows a channel with a device, a longitudinal section; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one.

The device contains a self-propelled frame 1 with a 2-wheel drive, a traction winch 3 and a cantilevered boom 4 attached to the rear part of the frame 1. At the free end of the boom 4, a trapezoidal anchor 5 is fixed, the lower edge of which is shaped like a transverse channel profile, pointed and fitted teeth 6. The anchor 5 is fixed deflecting blocks 7 and the steering support wheel 8 with a drive of 9 vertical movement. The winch 3 by cable 10 passing through the deflecting blocks 7 is connected to the towed paver 11. The blocks 7 are mounted on a horizontal axis 12, perpendicular to the axis of the shaft 4.

The hydraulic towing paver operates as follows.

Before the start of concreting, preparatory work is carried out, consisting of cutting across the canal at a distance of a step of movement of the device for towing with a width of 10-15 cm (when concreting canals up to 1 m deep, the device works without meters), as well as placement of the paver 11 and the device at the initial working positions and their connection with each other by a cable 10. In the initial working position the anchor 5 with its teeth 6 is mounted in the tool, and the steering support wheel 8 is transferred by the drive 9 into the upper extreme position e.

After that, the paver 11 is towed by the winch 3 using a cable 10 passing through the deflecting blocks 7. When a paver 11 is applied to the device by the vertical component of this force from the cable 10 to the blocks 7, the pointed anchor 5 is equipped with teeth 6, is buried in the soil along the channel profile, ensuring reliable device rooting. Moreover, with an increase in the movement force of the paver 11, the vertical component of this force also increases, increasing the depth of the anchor 5 into the ground, which ensures high reliability of the proposed device. The winch .3 is controlled from the console located on the paver 11. Tilting the device relative to the anchor 5 in the ground of the channel counteracts the mass moment of the device, with the center of gravity in the longitudinal direction located at the greatest possible distance from the anchor 5.

After towing the paver 11 by the drive 9, the support wheel 8 is moved to the lowest position, the anchor 5 is recessed from the ground and raised to the transport position, the drive 2 is moved by the self-propelled frame 1, and the device, winding the winch 3, the cable 10, is moved along the bottom of the channel to a new working position, the device being maneuvered by the steering wheel 8.

Dug across the canal during the pulling when towing the paver 11 are covered with soil, which is in the channel in the form of a spillage and accumulates in front of the paver 11. When the paver 11 is moved, the soil arrived at the mooring unit is tamped with the guide section of the paver 11.

The largest distance between the working positions of the core device depends on the rope capacity of the traction winch 3 and the multiplicity of the polyspast.
