SU459339A1 - Conveyor of two Russian units for the production of slab concrete and reinforced concrete products from rigid concrete mixtures - Google Patents

Description

The invention relates to the precast concrete industry, in particular, to the manufacture of slab concrete and reinforced concrete products, such as road and airfield slabs of coatings, panels for house building, etc.

A known two-line conveyor plant for the manufacture of slab concrete and reinforced concrete products from rigid concrete mixtures, including trolley molds, a molding machine, a heat treatment post, and mechanisms for lifting, moving and converting the trolley molds to the lower Russian.

Vibrating mechanisms are used in the known installation for compacting concrete, and in the heat treatment chamber of the form-trolley they move in a horizontal position with an open top surface, which increases the heat treatment time and also requires large production areas.

The purpose of the invention is to improve the quality of products, reduce the production area and increase productivity.

This is achieved by the fact that the post forming is made in the form of a reciprocating movable bar mounted perpendicular to the movement of the carriages of the beam with rollers and a bunker for simultaneous laying, sealing and smoothing of the concrete mix, a pusher for palletizing and moving the pouch and a tilter for the subsequent translation of the trolley forms to a horizontal position.

FIG. 1 shows schematically the described installation; in fig. 2 is a section along A-A in FIG. one.

The installation contains trolley-forms 1, a mechanism for moving forms along the upper shaft 2, a preparation station for concreting 3,

post forming, including a bar with rollers 4 and a hopper 5, a mechanism for transferring the forms to the vertical position b, packing and moving the package 7 mounted at the end of the post of forming, a post of heat treatment 8, a mechanism for transferring the forms to the horizontal position to the lower rus 9 located at the end a heat treatment station, a mechanism for moving the molds along the lower rus 10, and a lifting mechanism 11.

The installation works as follows.

The forms-trolleys 1 with the help of the mechanism for moving along the upper tier 2 successively pass in a horizontal position the preparatory station for concreting 3, where

the reinforcement cages are cleaned, lubricated and laid, then they are fed to the post where the vibration-free laying, compaction and smoothing of the concrete mix is performed using a bar with rollers 4 and a hopper 5, making a returnable movement, perpendicular to the direction of movement of the form-trolleys. Next, the trolley forms with the molded articles by mechanism 6 are brought to a vertical position and are assembled into the bag by the mechanism of baling and moving the bag 7 and are transported through the heat treatment posts 8, which are carried out by electric heaters through the walls of the cart cars in a closed space. At the end of the post heat treatment, the finished products are removed and, using the mechanism 9, the trolley shapes are turned into a horizontal position with their simultaneous transfer to the lower rus. Then, using the movement mechanism 10 and the lifting mechanism 11, the carriage forms are returned to the upper Russian, and the working cycle is repeated.

Subject invention

A two-way conveyor plant for the manufacture of slab concrete and reinforced concrete products from rigid concrete mixtures, including forms-trolleys, a device for molding, a heat treatment post and mechanisms for lifting, moving and transferring to the lower Russian forms-trolleys, characterized in that improving the quality of products, reducing the production area and increasing productivity, post forming is made in the form of a reciprocating 5 mounted on the upper floor, perpendicular to the movement of mold wagons whisker with rollers and the hopper for the simultaneous laying, sealing and smoothing the concrete mix, and heat treatment for post translation equipped tilter

form carriages to a vertical position, a pusher for palletizing and moving the bag and a tilter for subsequent translation of the car forms to a horizontal position.
