Abstract

This invention relates to mechanized systems for the shipment of products from sludge shafts. The purpose of the invention is to increase the performance and reliability of the unit for cleaning the mine water catchments. The unit includes two winches, one of which is installed in the reservoir. The cable receiving drum (B) 4 of this winch and the axis 5 of its rotation are made with internal cavities 6, 7 and perforation holes (PO) 8. The latter connects cavities 6.7 between each other and with the internal volume of the reservoir. In the cavity 6 between B 4 and its axis 5 metal balls 9 are placed, the diameter of which is larger than the diameter of PO 8. Axis 5 is fixed on frame 10, and the cavity of axis 5 is connected to the pump (hydraulic elevator) by means of a suction pipe 13. When pressure is applied in the suction pipe 1 3 and cavity 7 of axis 5, a vacuum is created. Due to this, through the software 8 and the cavity 6, the products of the sump of the catchment basin are moved, moving by the transport-mixing body in the form of a scraper. 2 hp f-ly, 3 ill. 77 bc (L

The invention relates to mechanized systems for the shipment of products from sludge shafts with unsatisfactory indicators of the speed and uniformity of solid jigging typical of mines using hardening development systems, in particular, devices for cleaning mine sumps and septic tanks, which require forced reaming and feed to the suction organs of products of sediment in the whole of the pulp, and can be used in systems with suction pumps (centrifugal, pore nevymi, inkjet) for shipment and mixtures of coarse clay and cement slurries with low-performance stirring or averaging.

The purpose of the invention is to increase the performance and reliability of work.

Fig, 1 shows a water collector with a device, a longitudinal section; FIG. 2 — winch with perforated drum and axle; longitudinal section in FIG. 3 - a loop of a cable with the fixing probe,

The unit includes two winches 1 and

2 (FIG. 1), one of which (1) is additional, installed above the allowable level I-I of the reservoir flooding 3, and the other (2) directly in the catchment 3, in the lower

its part, located below level II-II of the accumulation of sludge products,

The cable receiving drum 4 (FIG. 2) of the winch 2 and its rotation axis 5 are made with internal cavities 6 and 7 and perforation holes 8 connecting the cavities 6 and 7. between themselves and with the internal volume of the water tank.

3 (FIG. 1); In the cavity 6 (FIG. 2), metal balls 9 are placed between the drum 4 and its axis 5 with the ability to rotate when the drum 4 rotates. The balls 9 are larger than the diameters of the perforations 8. The axis 5 is fixed to the frame 10 along two the ends 11 and 12, and the tip 11 is muffled. The cavity 7 of the axis 5 on the side of the tip 12 is connected by means of the suction pipe 13 to the pump, in particular, to the hydraulic elevator 14 (FIG. 1) fixed on board the catchment 3, fed from the outlet

It is assorted into drainage tanks or trolleys (not shown).

One of the cables 17 (cargo) of the winch 1 is sequentially in contact with the deflecting heading block 18 fixed to the soil of the catchment 3 (to limit the displacements of the winch 2 along the catchment 3); one turn with perforated drum 4 winches 2; with the scraper 19, the Second cable 20 of the winch 1 is connected to the scraper 19 via the main block 21,

Before turning on the unit for cleaning the sump 3, the grooves (not shown), through which the mine water enters the sump, and through the open valves 22 connecting the sump 3 with the suction pads 23 of the main outflow pump 24, are pumped out before the level II-II and then shut off valves 22,

The operation of the unit is provided by one worker and is carried out as follows.

Pressure is applied to the outlet 15 of the dewatering rod. As a result, a vacuum is created in the suction pipe 13 and in the cavity 7 (FIG. 2) of the axis 5, through which the products of the sump collector 3 are drawn in through the perforations 8 and the cavity 6 (FIG. 1) and transporting them further along discharge station 16,

. During the reciprocating movement of the scraper I9 along the water collector 3 due to the alternate retraction of the cables 17 and 20 with the mechanized winch 1, the ropes 17 and 20 are agitated, mixed along the entire length of the water collector 3 and the products are collected from the winch 2; the mechanized drive of rotation of the perforation drum 4 (FIG. 2) due to the movement of the envelope of the cable 17 in a single turn, resulting in re-generation of the balls 9 in the cavity 6 and the shock treatment of the surface of the drum 4 and the axis 5 forming the cavity 6, which virtually eliminates sticking of the perforations holes 8, reducing the difference in operational and technical performance of the immersion suction pumps, in particular the hydraulic elevator 14,

If necessary, a routine inspection, the winch 2 can be moved by the scraper 19 to the level of the winch 1 after the preliminary disconnection of the plowing (quick disconnecting) block 18 with the cable 17. The reverse movement of the winch 2 into the water collector is provided as follows. From the cable inlet 17 between the winch 1 and 2, loop 25 is formed (Fig. 3) into which the dowel 26 is inserted for fixation. When the cable 20 is tightened, the pin 26 in the loop 25 goes to the drum 4 and abuts the frame of the winch 2 ( Fig. 1) provides for its movement deep into the catchment basin 3 at any place along its entire length (if necessary with a corresponding preliminary buildup of the suction pipe 13 at the place of its connection to the hydraulic elevator 14).

After returning the cable 17 with the loop 25 to the winch 1, the pin 26 is disassembled and the loop 25 is opened on the cable 17. The unit is again ready to work.

Embodiment design options may be as follows.

The mechanized drive (motor) of drum 4 of winch 2 can be connected to drum 4 by means of an angle column and placed directly above winch 2 in a water collector 3. above level I-I.

With remote or automated control, a sealed drive of rotation of two wire receiving perforated drums of the winch can be installed on the latter, located below level II-II, and the cables 17 and 20 are stored on its drums to move ckpe6Ka 19. When the perforations 8 are periodically closed on the dead drum The cable itself, in its turn, is radiated, meet answer B on the reel of winch 1, which does not disrupt the suction front of the products and allows for more efficient POSSIBILITY sticking on the outer surface of the drum 4 due to reduction rope wound.

A kinematic connection between one of the drums of the winch 1 and the drum 4 of the winch 2 can be performed in a twist-chain plate, covering the sprockets attached to their bar.

bans The cable 17 has no contact with the drum 4, and the cable 20 is stored on the latter.

Winch 1 can be three-drum and one of its cable receiving drums is connected to the drum 4 of the winch 2 by an endless cable to ensure irregular rotation, and the remaining drums of the winch 1 are operated by storing the cables 17 and 20, contacting only the scraper 19, and the cable 20 with another block 21.

Cable 17 can bend around an additional 5-drum pulley attached to

the end of the drum 4, to reduce the load on the perforated surface of the drum 4.

Instead of metal balls used stone boulders.

Perforation holes 8 are sewn in the form of slots.

The axis 5 is rigidly connected to the drum 4, i.e. performed with the ability to rotate with the latter relative to the frame 10.

The cable 17 without full bending of the drum 4 only touches it along the generatrix of a certain sector due to the retention of the winch trough mechanism by the deflecting rollers.

The design of the unit for cleaning the shaft water collectors has a large operational capacity, since in practice it eliminates sticking of perforations 8 for the suction pipe 13. At the same time, the transport-mixing body (scraper 19), kinematically connected in series with two cable wires, is simpler in design and operation. - with the reels, one cargo cable 17 and ensuring stationary installation of the pump 14 in the collector 3, which does not require the attendance of service personnel directly in a catchment basin and increases reliability of work.
