The invention relates to the construction industry, to process equipment for the manufacture of precast concrete.

The purpose of the invention is to increase productivity.

FIG. 1 shows a conveyor line, top view; FIG. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 is a diagram of the movement of form packages in heat chambers.

The conveyor line for the manufacture of reinforced concrete products contains a central return branch 1 and the preparation of forms 2, which is located between the parallel branches 3 and 4 of the molding, the heat and humidity treatment and stripping, and combines them.

On the central branch are the post 5 of cleaning and lubrication of the molds, the post 6 to close the end boards, posts 7 and

8 installation of reinforcement, post 9 hydronat of reinforcing bars.

At the beginning of each of the branches 3 and 4 are located vibroplatform 10, post 11 control of products, post 12 laying forms in vertical packages 13, tunnel chamber 14 of thermo-humidification processing, post 15 disassembling vertical packages 13, 16 and 17 strips of reinforcing rods. In the base of the line, live rolls 18 are mounted, and at the ends of the branches, transfer devices 19 are arranged in the form of lifting roll tables.

Each of the posts 12 and 15 has a hydraulic lift 20 arranged symmetrically to the axis of the conveyor line, and the side posts 21 with supporting arms 22 equipped with a hydraulic lift. The actuator 23 and the return spring 24. The support arms 22 serve as temporary supports, which fix the accumulated package of forms in the raised position. Inside kaOs Och

measures 14 along its longitudinal axis, and also outside the chamber, covering posts 12 and 15, a flexible, for example chain, infinite drive 25 is mounted. The drive 25 has spring-loaded pushers 26 spaced from one another at a distance equal to half the length of the endless drive and a multiple step of moving a package of forms.

Branches 3 and 4 have a portal 27 with a cross-beam 28. Along posts 7–9 on both sides of the central branch, monorails are suspended for the hoist, providing the supply of rebar in a vertical position, and in a horizontal position - rebar.

The conveyor line works as follows

In the initial position, the roller tables are filled with forms 2. The support arms 24 posts 12 and 15 are moved out of the working area. A mold with a freshly molded article is located on the vibrating plate 10. A drive for moving the molds along the roll table is turned on and the mold is moved to post 11 to monitor and eliminate defects. At the same time, at the station 12, a package of one or several forms with products of the hydraulic lift 20 rises to a height of one step. The hydraulic actuator 23 is disconnected and the support arms 22, under the action of return springs, enter the sides of the mold. The lift is switched to a lowering and the stack of forms is kept in the raised position by the levers 22. This process is repeated until the complete set of the packet.

Then the drive 25, operating in a reciprocating mode, pusher 26 alternately moves the packets along the tunnel chamber, and by the time the packet is collected at post 12, space is available at the beginning of the chamber for the next packet, which is pushed into the chamber 14.

Disassembly of the package at station 15 is carried out in a similar manner. The product-free forms at the station 17 are captured by the transfer device 19 and alternately from the branch 3 and the branch 4 are installed on the central branch 1 and returned to the posts for preparing the molds, fittings and hydronate. From post 9, the hydronat of the mold is alternately directed to the branches 3 and 4 to the posts 10 of the molding.
