Abstract

The invention relates to earth moving equipment and can be used in devices for the development of frozen soils. The aim of the invention is to improve the reliability of the device by simplifying the design. The device includes a base machine 1 connected by a hydraulic cylinder (HZ) 2 controls with an upper frame (P) 3, a suspended R 4 and a mechanism 5 for sliding P. On P 4 there are installed screw working members (RO) 27. Two pairs are mounted symmetrically on P 3 installed in perpendicular planes of bars 14 with a drive of their rotation in the plan. The sliding mechanism 5 P is made of tubular sliders 6, guide rods 7 and locking mechanisms 8. Each of the latter comprises a rack, gear and brake. Before work, P 3 and P 4 are as close as possible. Bars 14 and PO 27 are installed on the developed soil and include the drives of their work. Bars 14 cut through the slots, and PO 27 are screwed into the central part of the cut out soil. After cutting the soil to a predetermined depth HZ 2 raises P 3 along with bars 14 with the brakes off. Bars 14 are rotated 45 ° and HZ 2 is fed into the ground to cut through new gaps that form an octagon. The resulting ground strip is detached at the lower end of HZ 2 with the brakes on. The unloading into the transport is carried out with the reverse rotation of the PO 27 and the idle operation of the bars 14. 4 sludge.

weighty P 4 and mechanism 5 for expanding P. On P 4 there are installed driving screw bodies (RO) 27. On P 3, two pairs of symmetrically mounted in perpendicular planes of bars 14 are mounted with rotation driving in the plan. The sliding mechanism 5 P is made of tubular sliders 6, guide rods 7 and locking mechanisms 8. Each of the latter includes a rack, gear and brake. Before work, P 3 and P4 are as close as possible. Bars 14 and PO 27 are installed on the developed 15 soil and include the drives of their work.

The invention relates to earth moving equipment and can be used for the development of frozen and other soils.

The purpose of the invention is to increase the reliability of the device by simplifying the design.

FIG. 1 shows a device for the development of frozen soils; in fig. 2 is a section A-A in FIG. one; in fig. 3 - bar, side view; in fig. 4 - cut out device of the pillar of soil before excavation, view in plan.

The device for the development of frozen soils includes a base machine 1, on which a control hydraulic cylinder 2 is fixed, connected to an upper frame 3 connected to a supporting frame 4 by means of a mechanism 5 extending frames made of tubular sliders 6, guide rods 7 and locking mechanisms 8 containing mounted on the slider 6, the toothed rack 9, which interacts with the toothed wheel 10 mounted on the supporting frame, sitting on the shaft 1 1 with the brake 12.

On the upper frame 3, two pairs of bars 14 are installed in mutually perpendicular planes symmetrical to the central vertical axis 13, each of which has a drive 15 made of a motor 16, a gear 17, a drive sprocket 18 AND a driven sprocket 19 mounted on a guide arrow 20 with a tensioning mechanism 21. The rotational drive of the bars 14 in the plan includes the output

Bars 14 cut through the slots, and PO 27 are screwed into the central part of the cut out soil. After cutting the soil to a predetermined depth HZ 2 raises G 3 along with bars 14 with the brakes off. Bars 14 are rotated 45 ° and HZ 2 is fed into the ground to cut through new gaps that form an octagon. The resulting ground strip is detached at the lower end of HZ 2 with the brakes on. The unloading into the transport is carried out with the reverse rotation of the PO 27 and the idle operation of the bars 14. 4 sludge.

shaft 22, made in one of the gearboxes 17, mounted on the shaft 22 of the inclusion coupling 23, brake 24, is a bevel gear 25 and bearing 26. Screw tools 27 with their drive 28 are installed on the base frame 4. I

The device works as follows.

Before working, frames 3 and 4 are as close as possible (Fig. 1). The screw bodies 27 and the lower parts of the bars 14 are installed on the frozen ground, the drives of their rotation are turned on and the control hydraulic cylinder 2 carries them into the ground. The bars are cut into four vertical slots (solid lines in Fig. 4) and the working bodies are screwed in 27.

After cutting the soil to a predetermined depth, the bars are raised by a hydraulic cylinder 2 above the ground surface by expanding frames 3 and 4 with the brakes 12 turned off. Then they turn on the clutch 23 and rotate the bars 14 from the engine 16 at a 45 ° angle, turn off the clutch 23 and The position of the bars 14 is fixed by the brake 24. The cutting of new slots is made (in Fig. 4 - dashed lines) when the bars 14 are fed down by the hydraulic cylinder 2. The resulting eight-sided rear sight tube fixed on the screw working bodies 27 is torn off at the bottom end using the hydrocyle RDA 2 with the brakes on 12. Unloading of the soil into the vehicle is carried out with reverse rotation
