The invention relates to the production of building, mainly reinforced concrete, products on conveyor lines, as well as can be used in the manufacture of any products but to a specific technological cycle, especially in the conditions of hot workshops and similar harmful industries.

A typical production line for the manufacture of reinforced concrete products, containing technological posts located on the conveyor line 1.

The disadvantages of the known line are the inefficiency of the placement of the process equipment and, as a consequence, a significant production area.

Closest to the present invention is a two-line process line for the production of reinforced concrete products, which contains equipment for technological operations located on the upper deck, a heat treatment chamber, molds, devices for horizontal transportation and vertical transportation of molds from Rus to Russ 2.

The disadvantage of this line is the unsatisfactory working conditions of workers associated with the movement of the conveyor and forms directly through technological posts in the horizontal direction, as well as the limited service area of the form around the perimeter of the latter, resulting in increased labor intensity and reduced labor productivity.

The purpose of the invention is to improve working conditions and safety.

This goal is achieved by the fact that two production lines for the production of reinforced concrete products containing equipment for technological operations, located on the upper deck, heat treatment chamber, molds, devices for horizontal transportation and vertical transportation of forms from Rus to Rus, devices for transporting forms are made in the form of self-propelled carts with mechanisms for raising and lowering forms, and the upper rus is made with openings for the forms at the locations of technological th equipment, the trolleys are arranged on the lower tier.

FIG. 1 shows the proposed process line, a plan view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

Technological line contains the upper 1 and lower 2 Rus. Technological posts 3 are located on the upper rue — equipment for performing preparatory, molding, finishing, stripping and other operations, as well as spare technological posts duplicating the main ones. At the same time, for the purposes of sound insulation, thermal insulation and insulation from other harmful effects, partitions were installed between the posts 4.

The lower rus is a transport route on which devices 5 are mounted for transporting molds,

containing devices for horizontal transportation of molds 6 - self-propelled trolleys 7 with remote control, combined with devices for vertical transportation of molds from rus to Rus and back - hinged lever 8 devices mounted on trolleys 7.

Along the entire length of the upper tier 1, in places corresponding to the placement of technological equipment 3, openings 9 are made for forms 6, equipped from the top

There are safety guards (railings, stairs) 10 made along their entire perimeter to the height of the forms and allowing free access to the form.

All known structural solutions can be used to accommodate the heat treatment zone. In the proposed embodiment, the line on the lower shaft 2 parallel to the transport path is located the heat treatment zone 11.

In this case, the line is equipped with mechanisms 12 for transferring forms to the heat treatment zone 11 and back, installed, for example, on the lower shaft 2 along the ends of the line. The line is operated as follows.

Form 6 on the trolley 7 is fed along the transport route of the lower tier 2 and is set to a position corresponding to the location of the specific post of the upper tier 1 line. With the inclusion of the device 8, the form b rises to the upper Russian, is placed in the corresponding project and fixed in the design position. Thus, the process station is becoming fully equipped and ready to carry out the relevant operations.

According to the rhythm of the line

after the preparatory operations in the first post, form 6 is lowered by fixture 8 and moves along the transport route of the lower tier 2 on the trolley 7 to the next post. Then rises

Q is set in the design position, the set is thereby the same post-molding or finishing work, similar to that described.

In case of malfunctions of the technological equipment at one of the posts, without violating the rhythm of the line, the form can be transferred to any other, for example, spare, post to perform the corresponding operations. Spare technological post can also be used for simultaneous work with the main post. The line operation rhythm is also guaranteed by the availability of the required number of device 5 on the transport route of the lower russ 2. The number of devices 5 is no more than three (one trolley moves in the left part of the lower rus to the middle of the span, the second in the right part to the middle of the span and a third spare). From the last post of the line, form 6 with a freshly molded product descends into the lower rus 2 and is transferred along transport route to mechanism 12 for transfer to the heat treatment zone. After passing through the heat treatment zone, the form with the finished product returns to the transport route of the lower rus, also using the same mechanism 12, and is again mounted on the carriage 7. It is then lifted by the device 8 to the upper rusle, the exchange 1 is in the opening and fixed in the design 11 . After stripping and removing the product from the form, we repeat the cycle. The technical and economic efficiency of the application of the present invention consists in a significant improvement in the working conditions of the workers and an increase in safety, as well as, consequently, in an increase in the productivity of the line.
