Abstract

Usage: in the construction industry. SUMMARY OF THE INVENTION: transmission trolley. it has a lifting and lowering platform with a supporting surface that ensures the placement of two hoppers on it, which interact alternately with the carriage located on the portal console, and the mounting support for installing the removable hopper is made with rigid L-shaped grips in contact with the hoppers through the longitudinal collars of the latter. 2 ill.

Description

The invention relates to the construction industry, in particular to the laying of concrete mixture in molds.

A known installation for laying concrete mixture comprising rail tracks with a self-propelled platform mounted on them above the molding posts and self-propelled hoppers mounted on the concrete overpass at the top of the platform.

The disadvantage of this installation is the inability to ensure continuous laying of the concrete mixture, because the self-propelled platform must make constant movements between the concrete-carrying trestle and molding stations for receiving silos with concrete mixture and unloading them into molds.

Closest to the proposed solution in terms of technical nature and the achieved results is the installation for laying concrete mixture. contains our rail guides with a self-propelled portal mounted on them, a trolley mounted in the portal with a laterally movable trolley with a support device, a removable hopper and a lifting and lowering mechanism, as well as a transfer trolley with removable hoppers interacting with the hooks of the traverse of the lifting and lowering mechanism. The disadvantage of this installation is its complexity and low productivity for laying concrete mixture due to the time loss in moving the self-propelled portal from the mold to the transfer carriage and back to receive the hoppers with concrete mix and unload them into the molds.

The purpose of the invention is to simplify the design and increase productivity.

This goal is achieved in that in the installation containing rail guides, a cantilever self-propelled portal, mounted on it a laterally movable carriage with a support device for installing a removable hopper and a transfer carriage for feeding hoppers, a support device for a removable

the hopper is made with rigid L-shaped pickups and longitudinal shoulders fixed respectively on the carriage and the removable hopper, and the transfer trolley is equipped with a lifting and lowering platform with the possibility of placing two hoppers on it, interacting alternately with the carriage on the portal console.

In Fig. 1, there is shown an installation for laying concrete mixture, a plan view, in Fig. 2 is a view along arrow A in Fig. 1.

The installation for laying concrete mixture in molds consists of a self-propelled portal 1 mounted on rail rails 2, a transfer trolley 3, removable hoppers 4. The self-propelled portal is equipped with a remote console 5. The carriage 6 is mounted on the portal and is movable in the transverse direction, to the frame of which it is rigidly attached L-shaped grips 7. The transfer trolley has a lifting and lowering platform 8 and a mechanism 9 for lifting and lowering the platform. On removable bins 4 from opposite sides, longitudinal collars 10 are rigidly fixed.

Installation works as follows. ,; - 4V;:}; ,,: ;; v ;; .-:.

A self-propelled portal 1 is mounted above the mold 11, made for example in the form of a cassette. Under the console 5 of the self-propelled portal, to which the carriage 6 is fed at that moment by the drive 12, the transfer car 3 with two removable hoppers 4 mounted on its lifting and lowering platform 8 drives up with the help of the drive 13, the truck stops so that one of the hoppers loaded concrete mixture, with its longitudinal bores 10 entered into the grooves formed by l-shaped pickups 7 of the carriage 6.

The platform 8 is lowered by the mechanism Ј, and the hopper 4c with the concrete mixture is suspended in the arms 7 of the carriage 6. After that, the carriage with the hopper is moved to a position above the mold 11 where the concrete mixture is being laid. Transfer trolley 3 with empty hopper 4 drives off under load

concrete mixture from its supply path from the concrete mixing unit and then returns again under the console 5 of the portal.

After placing a portion of the concrete mixture into the mold 11 from the first hopper, the carriage 6 moves to the portal console 5 and stops above the transfer carriage. The platform 8 of the transfer carriage rises and then lowers, taking on an empty hopper from the carriage 6.

Then the trolley moves to a new position, in which the first hopper exits with its shoulders 10 from the grooves formed by the L-shaped pick-ups 7 of the carriage, and the second hopper, provided with the mixture, enters them. The platform 8 is lowered, the hopper with concrete mix hangs on the hooks 7 and the carriage is fed to the mold.

The transfer trolley with the first hopper leaves for loading with concrete mixture and then the process is repeated.

The economic effect of the proposed technical solution in comparison with tbpn is achieved due to the continuous supply and laying of concrete mixture.
