Description

one

This invention relates to devices for the manufacture of reinforced concrete products in forms.

A known installation for the manufacture of reinforced concrete products includes two conveyor belts with movable: and with the help of pulleys trolley forms and molding molding equipment placed on the upper and lower Russa, respectively: ore, heat treatment chambers and elevators-descenders.

However, in the known installation, the upper and lower conveyors are located one above the other, forming a vertically closed conveyor line, which makes the lower Russian installation difficult to access.

The purpose of the invention is to provide ease of operation and maintenance, as well as to simplify the design of the installation.

This is achieved by the fact that the axis of the lower conveyor in terms of is offset relative to the axis of the upper conveyor and parallel to it, and the ends of the conveyors are connected by inclined bases on which lift-descenders are installed with the possibility of moving along the track; moreover, each of the lift-reducers is made in the form of a two-axle bogie, in which one wheel axle is mounted below the level of the other; In addition, in the middle part of the upper conveyor an intermediate pusher is installed, made of several freight carriages, but at least Lara of which is equipped with a controlled coupling mechanism.

FIG. 1 shows the upper conveyor, general view; in fig. 2 - the proposed installation plan; in fig. 3-section on A - A in FIG. one; in FIG. 4 shows a section along B - B in FIG. 2; in fig. 5 is a section, but B - B in FIG. 2; on

FIG. 6 - pusher operation scheme.

The installation contains an upper conveyor L and a lower conveyor 2 arranged in two Rus, on which pushers 3 and 4 move form-trolleys 5.

A molding equipment was installed above the upper conveyor 1 on the overpass 6: the vibrating-unloading machine 7, the paver 8 and the spreading machine 9 with finishing mechanisms 10. This equipment is able to move but the overpass 6 along the conveyor line to change it when the technology changes.

A molding machine 11 is installed in the molding station with four sliding

sides, which ensure the formation of reinforced concrete products on rigid mixtures with immediate stripping.

In the lower russ there is a slit chamber 12 of heat treatment of products, through

which passes the conveyor 2.

The axis of the lower conveyor 2 in the plan is offset from the upper conveyor and parallel to E in such a way that the lower rus is not directly below the upper one, but to the side.

The top of the slit chamber 12 serves as the floor of the workshop and is made out of removable reinforced concrete panels with insulation.

Along the turn, am, upper and lower conveyors, there is a rail track 14 laid on clone bases 13.

On the track, the winch-mounted movable winch 15 is mounted, runner, in the form of a two-axle bogie, in which one wheel axle is mounted below the other, ensuring the horizontal position of the bogie platform as it moves along the inclined base l3.

A pusher 3 is located in the middle of the molding line below the level of the upper conveyor. It contains three load-driving carriages 17, a chain drive 18 for moving the carriage and a drive 19 of the pusher.

Two of the loading carriages 17 are connected by a tight 2U, and a third is connected by a controlled coupling mechanism 21.

The pusher 4 is located in the patch along the upper conveyor and contains two freight carriages 17 with a chain drive 18 and a drive 19 of the pushers.

On the upper conveyor, the products are molded and finished; on the lower conveyor, they are heat treated in a slit chamber.

The cleaned and lubricated pallet-trolley with a volumetric reinforcement cage is moved by the pusher to the molding posg and lowered onto the vibration plate.

Then, the longitudinal and transversal grades of the molding machine I are closed, the listotobrazovateli are introduced, the concrete mixture is laid by the concrete paver and compacted on a vibrating plate.

Thereafter, the immediate dismantling of the articles is carried out, and the noddon-trolley is fed to the finishing posts of the articles.

The pusher 4 at the same time removes the pallet from the transfer carriage 16 and places them in a molding machine.

The pusher 3 removes the pallet trolley with the molded product from the molding machine, arranges them with a certain step at the molding section and at the finishing station and pushes it onto the lift-sinker 16.

The latter lowers the product on the lower rus and transmits it to the slit chamber 12.

After the end of the heat treatment cycle, the noddon-trolley with products is delivered by an elusive trolley to the upper rus, where finished products are removed by crane from the trolley and moved to the finishing section.

Line operates in a pulsed 1co.nweier mode.
