Abstract

The invention relates to hydraulic construction and, in particular, to devices for the continuous supply of soil materials from the quarry to the place of dumping it at one or several points during the construction of earth dams. The purpose of the invention is to increase efficiency by expanding the service area. The device includes loading and unloading units, a closed overpass and a carriage conveyor. A closed overpass is formed by end and intermediate sections, each of which, in turn, consists of sections connected in series and mounted on track supports 28 by means of frames 26 fixed to beams 27 of these supports, equipped with telescopic supports with cross member 21 and hingedly connected to it hydraulic cylinders 24. Traverse 21 is connected by means of grippers 23 to sections of the platform, on which, by means of carriages, folding racks 18 are mounted with guides 17 interacting with rollers of conveyor carriages. 1 hp f-ly, 4 ill.

. The overpass is formed by end and intermediate sections, each of which, in turn, consists of sections connected in series and mounted on hods, supports 28 using frames 26 attached to telescopes 27 equipped with telescopic supports. The invention relates to hydraulic engineering, in particular, to devices for the continuous supply of soil materials from the quarry to the place of dumping it at one or several points during the construction of earth dams.

The purpose of the invention is to increase efficiency by expanding the service area.

FIG. 1 shows the proposed device with a loading unit and a receiving bunker; in fig. 2 - node I in FIG. 1; in fig. 3 — device with separate sections, plan; FIG. 4 is a section A-A in FIG. one.

The embankment erection device comprises a loading unit 1 with inclined chutes 2, a carriage conveyor

3 consisting of container carts

4, connected by a hitch 5 and pieces of elastic tape 6, and a magnetic freak. drive 7. On the overpass 8 are mounted on sleepers 9 rails 10, along which the conveyor 3 moves.

The overpass 8 consists of separate curvilinear and straight sections 11 and 12, respectively, which are connected to each other in the end sections (modules) 13 and intermediate 14. On the opposite end section (module) opposite to the boot node (module), an unloading section is mounted the assembly consisting of a tray 15 fixed on the outer side of the overpass, the baffle wall 16 and a curved guide 17 mounted on the folding stand 18. The baffle wall is also installed on the boot unit. The tray and the copier are mounted on the carriages 19 and fixed in the required place by clamps (not shown) on the steps of the rack 8. The guide is installed with the possibility of interaction with the roller, which is fixed on the conveyor carriage.

version 21 and hydraulic cylinders 24 pivotally connected to it, Traverse 21 is connected by means of grippers 23 to sections of the platform on which folding racks 18 are mounted by means of carriages 18 with guides 17 interacting with rollers of conveyor carriages. 1 hp ff, 4 ill.

Sections (modules) 11 and 12 of the platform are fixed on telescopic supports 20 by means of crosshead 21, hinged supports 22 and grippers 23. Telescopic supports are equipped with power cylinders 24 and mounted on a turntable 25 fixed not. The frame 26, which in turn is fixed to the beams 27 of the undercarriage 28, The undercarriage frame is provided with outrigger 29, with which the support can be detached and rolled out if necessary. The control panel is located in the area of the loading unit.

The overpass of the sections mounted on the hods of the supports forms a closed contour along which the conveyor-i continuously feeds the ground material from the loading point to the unloading point. Using a set of intermediate sections and movement of the end section, a closed loop of the required length is easily assembled.

The device works as follows.

From the quarry, the soil material is transported by continuous transport from the upper marks to the inclined trough 2 of the loading unit 1.

The soil in the inclined chute 2 accelerates to the speed of an unaccented load and enters the container carriages 4 moving in the loading area at a speed of 1/3 of the nominal system transport speed reported by the engines.

The laden composition accelerates to the rated speed and is formed into a continuous container link moving to the dumping site, such as a dam embankment map. At the unloading site, the emptying of freight containers (carts) 4 by tipping over with the help of guides 17,

interacting with rollers conveyor carts.

The empty conveyor is directed back to the loading point. After dumping the soil material, the volume of which should be sufficient to form the required layer thickness in the first zone of the map, two intermediate sections (modules) of the overpass are dismantled, the appropriate number of containers are first uncoupled and removed from the section or section. overpass;

Then, with the aid of a running support, it moves to the next zone, the end section (module) with the loading unit, and is connected with the intermediate modules (sections) of the overpass to the last zone, which adjoins the shore abutment, on which the inclined chute with the loading unit is arranged.

The loading unit is movably fixed with the help of cables, anchors on the shore abutment and can vary in height as the height of the embankment dam increases. Lift control is also carried out from the control panel.

Ground material is fed directly from the bunker to the last area of the dam map. At this time there is a remounting of the sections (modules) of the overpass to the new initial position.

By this time, technological operations on leveling, compaction of the soil layer are already completed. On the map

The dams, depending on its configuration, can be installed and work on several proposed devices that feed on soil material from one shore station.
