Description

one

The invention relates to the field of conveyor production of products, in particular, to the construction industry for the manufacture of reinforced concrete products by the conveyor method.

A known production line for the manufacture of reinforced concrete products, including movable rail tracks with the help of form-trolley driving devices, a molding station, a heat treatment station, and self-propelled transfer platforms.

The purpose of the invention is to reduce the metal intensity of the line, increase its reliability in operation and reduce the cost of manufacture. The goal is achieved by the fact that in the proposed line the rail tracks located at the molding station and transfer platforms are made with shaped grooves for undoing the wagons. The shaped grooves are made in the form of inclined bevels in the direction of the process flow at an angle, which ensures the cars to self-roll up to the fixed position, and the driving devices for moving the cars to trolleys are mounted on transfer platforms.

FIG. 1 is a top view of the processing line; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - figured groove on the track.

The technological line is made in the form of several parallel tracks 1,

on which trolleys 2 are installed. One of the paths is a molding line, and which is post forming, including the paver 3 and vibrating plate 4. The remaining paths are located in the heat chamber 5. Perpendicular path 1 from their ends are transfer paths 6, which can move self-propelled transfer platforms 7 and 8, having chain pushers 9,

drives 10 and rail tracks 11. On the tracks of the vibrating plate 4 and the path x 11 of the transfer platforms 7, 8 there are shaped grooves (see Figs. 2 and 3). If there are other posts after the post is molded, similar grooves are made on the rail tracks of these posts. The distances between the slots (size a, see Fig. 2) on the above paths are equal to the distance between the axles of the wheels of the trolleys. A group of shaped grooves inside each post by

its size is the same.

The shaped grooves are made in the rail in the form of BbieMiffl, which has an inclined bevel in the direction of the process stream. The inclination angle a (see Fig. 3) is selected from the condition of the spontaneous rolling of the trolley.

The minimum length of the slope of the figure groove is equal to the sum of the sizes M n N, where M is the distance of the guarantee that the trolley wheel falls on the slope of the groove, the absolute value of which is the same for all the holes and H

the variable slope of the groove, which increases from the vibrating plate to the transfer platform by the value of the specified gap S (see Fig. 2) between the trolleys. The end of the shaped groove structurally ensures the fixation of the wheels of the trolley.

Lini works as follows.

 The self-propelled transfer platform 7, moving along the transfer path 6, moves the trolley 2 with the steamed product to the molding line and the pusher 9 feeds it to path 1, this trolley in turn pushes the entire trolley located on the molding line with the opposite end at the same time, the trolley collides with the molded product onto the second self-propelled transfer platform 8. During this movement, the trolleys, arriving at the rail tracks of the vibrating table, the transfer platform and the length of the rail track between them, fall on their wheels on the bevels of the shaped grooves. The forced movement is stopped 1s, and the said carriages roll down the slope of the slots to a fixed position. As a result, a gap S is formed between the trolleys, which allows vibromolding to be carried out without transferring vibrations to the neighboring trolleys, and also allows the trolleys to move freely on transfer platforms. All movements of the trolleys on the molding line and in the thermal chamber are carried out by driving devices mounted on transfer platforms.
