Description

 The invention relates to the building materials industry, and in particular to processing lines for the manufacture of polystyrene concrete products.

 Known conveyor line for the manufacture of concrete products, containing conveyor branches, molds, trolleys, a heat treatment chamber, removal formations, mold preparation and molding / 1 /.

 The well-known conveyor line uses a technological process that allows only small-sized concrete products to be produced.

 Also known is a conveyor line for the manufacture of concrete products, containing molds, a heat treatment chamber / 2 /.

 The known conveyor line is complex in design and has low productivity in the manufacture of polystyrene concrete products, since the heat treatment chamber is not equipped with devices for electric heating of concrete.

 An object of the invention is to simplify the design and increase the productivity of the conveyor line in the manufacture of polystyrene concrete products.

 The solution to the technical problem is achieved by the fact that the conveyor line for the production of concrete products contains conveyor branches with trolley molds, along with conveyor branches in a technological sequence a paver, vibrating platform, finishing machine, heat treatment post, devices for stripping and assembling mold trolleys, molds are installed - trolleys are made with devices for electric heating of concrete mixture and weights, the conveyor line is equipped with a cargo tilter and a manipulator, load tilter and installed on the first conveyor branch in front of the manipulator, a plate conveyor is installed parallel to the first conveyor branch, the manipulator is installed between the first conveyor branch and the plate conveyor, the heat treatment post is made with a device for installing trolley-shaped trolleys in vertical bags, the vertical bag contains the number of trolley-trolleys multiple of three, the weights and pallets of the trolley-shaped trolleys are electrically conductive, three adjacent trolley-shaped trolleys are electrically connected to the lower trolley-shaped pallet etki prigruzami and the upper mold-trolley is brought first phase of the three-phase current, prigruzami lower mold trolley-connected to a second AC phase and the average shape prigruzami-trolley connected to the third AC phase.

 In FIG. 1 shows a conveyor line in plan. In FIG. 2 - a vertical package of three trolley-shaped trolleys.

 The conveyor line contains conveyor branches 1, 2 installed on the platform 3. Trolley forms 4 are installed on the conveyor branches 1, 2. The conveyor branches 1, 2 communicate with the transfer trolley 5. The trolley forms 4 are equipped with weights 6, the conveyor line is equipped with a tilter 7 weights 6. A plate conveyor 8 is installed parallel to the conveyor branch 1. The conveyor line is equipped with a manipulator 9 and a puller 10. A concrete paver 11, a vibratory platform 12, a finishing machine 13 are placed on the conveyor branch 2. At the end of the conveyor branches 1, 2 the heat treatment station is located 14. The conveyor line is equipped with a mobile container 15 and an overhead crane 16. The vertical package contains the number of trolley forms 4 multiple of 3, namely the lower trolley form 17, the middle trolley form 18, and the upper trolley form 19. The lower the trolley form 18 is equipped with a pallet 20 and a load 21, the middle trolley form 18 is equipped with a pallet 22 and a load 23, the upper trolley form 19 is equipped with a pallet 24 and a load 25. The trolley forms 17, 18, 19 are provided with folding sides 26, 27, 28, respectively, with folding sides 26, 27, 28 electric insulated from weights 21, 23, 25 and pallets 20, 22, 24 with facing sheets 29, 30, 31 and bushings 32, 33, 34 of hinged hinged flanges 26, 27, 28 with pallets 20, 22, 24, weights 21, 23 , 25 and pallets 22, 24, 26 are electrically conductive, trolley forms 17, 18, 19 at the heat treatment station 14 are electrically interconnected. The first phase 35 of three-phase current is connected to the pallet 20 of the lower trolley form 17, the pallet 20 is electrically connected to the load 25 of the upper trolley form 19. The load 21 of the lower trolley form 17 is electrically connected to the pallet 22 of the middle trolley form 18 and the second phase 36 is alternating current. The load 23 of the average form of the trolley 18 is electrically connected to the pallet 24 of the upper form of the trolley 19 and the third phase 37 of an alternating current.

 The conveyor line operates as follows. The paver 11 loads the concrete mixture into the trolley 4 on the vibrating platform 12. After loading and compacting the concrete mixture, the finishing machine 13 levels the surface of the molded product. Along the conveyor branch 2, the trolley 4 moves in the direction of the heat treatment post 14, while the tilter 7 lowers the load 6 onto the trolley 4. The bridge crane 16 moves the trolley 4 with the molded products to the heat treatment post 14 and sets them in vertical packages. After installation in a vertical package of trolley form 4 with a multiple of 3 (for example, 3), the first phase 35 of three-phase current is connected to the pallet 20 of the lower trolley form 17 and the load 25 of the upper trolley form 19, and to the load 22 of the trolley form 17 the second phase 36 of alternating current, to the pallet of the average form-trolley 18 connect the third phase 37 of alternating current. After electric heating of the products in trolley molds 4, the overhead crane 16 transfers the trolley molds from the heat treatment post 14 to the conveyor branch 1, the tilter 7 removes the load 6 of the trolley mold 4, the manipulator 8 takes out the finished products and places them on the plate conveyor 8. Remover 10 moves products from the plate conveyor 8 to a mobile container 15, which delivers the products to the warehouse. Transfer trolley 5 moves empty trolley forms 4 from the conveyor branch 1 to the conveyor branch 2 for subsequent loading with concrete mixture.
