SU220109A1 - HEATING AND CONVEYOR LINE FOR THE MANUFACTURE OF LARGE-SIZED REINFORCED CONCRETE PARTS - Google Patents

Description

This invention relates to process lines for the manufacture of reinforced concrete products, in particular large-sized ribbed PLITS.

Conveyor flow lines containing pe6eip post molding and product shelves with a vibrating plate and a paver and trolley-forms are known.

The increased work cycle, the difficulty of manufacturing MULTILAYERED products, the need to use transfer carts OR roller conveyors for transverse movement of form-trolleys significantly reduce the quality of well-known conveyor lines.

In the proposed invention, in order to shorten the cycle of the line and simplify its design, the LINE is made with separate posts, forming the edges and shelf of the product, placed respectively one after the other. The vibrating plate is installed at the rib shaping station and is associated with one of the pavers. The other paver has an infinitely variable drive speed drive, is equipped with a compacting vibrator and is located at the SHELF molding station.

FIG. } shows a flow-line diagram; in fig. 2 - trolley form.

Line includes rebar tensioning posts located on a closed ring, post laying of reinforcing grids 2, post forming rebar product 3 with vibrating plate and concrete paver 4, post forming post product 5 with concrete paver 6, having a drive of stepless speed control

displacement, equipped with a compacting vibrator, a post of exposure, reworking and laying of insulation 7, two vertical heat treatment chambers 8 and 9, a post of trimming rebar 10, a post of dismantling products} 1, a post of cleaning and lubrication of forms 12.

The manufacturing process is carried out in forms-trolleys 13, equipped with four wheels 14 for longitudinal movement and four wheels / 5 for movement in the transverse direction.

The work of the production and conveyor line occurs in the following sequence.

The trolley 13 is driven by the conveyor belt 16 to the tension post of the armature. Tension and installation of rod reinforcement occurs by means of automatic installation 17 using the principle of electrothermal tension. From the post of tension fittings trolley form driven conveyor

current and embedded parts. At this post, the sides of the mold are closed using hydraulic mechanisms. Further, the OP | RM trolley is conveyed by a conveyor drive to the post for shaping the edges of the product, where it is lowered onto the vibrating plate of the post using a hydraulic mechanism having lowering rails. Paver 4 places the concrete mix in the edges of the product. This mixture is compacted by the inclusion of a vibrating plate in the process of laying. Then the carriage form enters the post for shaping the product shelf, where the paver 6 places the concrete mixture in the slab part of the product, and also finishes the mixture with the rib and compacts the slab part due to surface vibrating with the help of a vibrating tamper. From this post, the carriage form with the molded product by the transfer device 18 is transferred to the post product reworking and insulant fill, if required.

In transmission, the carriage rolls along a transverse rail track, resting on it with four transverse wheels, and then enters a vertical steaming chamber. To increase the smooth operation of the flow-conveyor line, two cameras are operated through a cycle. Each camera operates according to the principle of bottoming palletizing and consists of lifting and lowering mechanisms and a transfer carriage located in the upper part of the transfer box.

The conveyor for moving the trolley shape at the bottom of the chambers is common to two chambers.

Camera mode - automatic. After the process of steaming products is completed, the carriage form is pushed out by the camera conveyor to the post of trimming the reinforcement.

At this stage, with the help of hydraulic mechanisms, the sides of the trolley form are opened and the armature-tensioned armature is cut off with a disk cutting machine 19.

After trimming the reinforcement bars, the form-carriage with the product is transferred by the transfer device 20 to the demolition station, where the product is removed by an overhead crane. Then the trolley form is transferred to the posts.

cleaning and lubrication. The trolley mold is lubricated while it is being moved by the tensioner using the set 21. Then the cycle is repeated.

Subject invention

1. Flow conveyor line for the manufacture of large-sized reinforced concrete ribbed products, containing a post for shaping ribs and rolls of a product with a vibrating table and a concrete paver and car forms with longitudinal movement along the line, in order to shorten the cycle of the line operation and simplify her designs

it is made with separate posts for shaping the ribs and the product shelf, placed one after another, respectively, with the vibrating plate installed at the rib shaping station and associated with one of the concrete pavers, the other of which is driven by an infinitely variable displacement velocity and equipped with a compacting vibrating rod, located at the shelf-forming post.

2. Line no. 1, characterized in that, for the purpose of ensuring the lateral movement of the carriages, the latter are provided with an additional group of wheels that are installed perpendicularly longitudinal.
