(54) TECHNOLOGICAL LINE FOR PUFFERING OF STOMETRING PRODUCTS IN CASSETTE. FORMS

The invention relates to the construction industry, in particular to technological installations for the manufacture of building products by the cassette method.

The installation for manufacturing building products in cassette forms is known, consisting of platforms mounted by wheel pairs on rail rails, on each platform there is a cassette form made up of separate shields connected at the ends by screw fasteners, equipment installed in a technological sequence and intended for preparation of forms, charging them with reinforcement, laying concrete mass with vibration treatment, chambers, heat treatment of molded products, receptions and return conveyors, before vacuum trolleys, stripping equipment and mechanisms for moving these platforms.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that in a production line consisting of a platform, mounted wheelsets on rail

guides, on each of which a cassette form is fixed, made up of individual shields connected at the ends with screw ties, equipment installed in the technological sequence and intended. for preparing molds, charging them with reinforcement, laying concrete with vibration treatment, heat treatment chamber of molded products, receiving and return conveyors, transfer carriages with mechanisms for moving these platforms to the device for stripping, the latter consists of a lifting and lowering frame with rail guides under the platform, supporting posts located on both sides of the frame, composite beams with turning sections connecting the stands with each other, and fixed on them the upper surfaces of the guides, On the racks, on one side of the lifting frame, supports are mounted on the base of the cassette form, movable supports for fixing the rotatable part of the beam in a horizontal position and locks to fasten the form shields during dismantling, and on the racks on the opposite side - a carriage driven by its movement guides of composite beams on which mechanisms are fixed for assembling and disassembling helical bolts of form shields and means; To fix these shields with a carriage when they are demolished; in this case, cassette-shaped shields interact with the guides of the composite beams by means of rollers mounted along their ends. In this case, the supporting surface of the platform for the cassette form is made in the form of a clamp, and a trolley for transferring platforms with cassette forms from the receiving station to the return conveyor is installed inside a thermal camera. FIG. 1 schematically shows a conveyor line in plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section bb into j of fig. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. 2. The cassette conveyor line contains postforming 1 (2 sections) with conveyor 2 concrete mixes, transfer carriage 3 with two rail tracks 4, 5 and push rods 6, 7 double acting, heat treatment chamber 8 with two conveyors: 9 and a returnable 10, a transfer carriage 11 inside the chamber 8, having one rail track and pusher 12, a device 13 for dismantling products and a cassette form 14 mounted on a conveyor platform 15 Form 14 consists of separation and molding boards 16 equipped with roller bearings of the same To with screws 18 and locking locks T, located on the ends of the shields 16 of the mold. 14. The transport platform 15 is provided with fasteners 20 with screws 21 securing the shields of the mold. The device 13 for raspalzbki products consists of support posts 22, a carriage 23 mounted on it with a lever-hydraulic mechanism and composite beams-guides 24 with a hydraulic cylinder 25. Support posts 22 have hydraulic pressure stops 26 for fixing in the worker. the position of the mold, and the composite beams are guides, 24 - spring-loaded supports 27 with an actuator 28. Lifting (skuskny frame 29 from the rail1 EIN, the path lies between the uprights 22 and is equipped with a hydraulic actuator 30. The device for dismantling 13 products has a movable wall 31, equipped with hydraulic actuators 32 with hydraulic actuators 33 and locking locks 19 for fixing the molds with the carriage 23. The cassette conveyor line works in the following way. In the mold 14, consisting of separation molding boards 16, a concrete mix is placed at the shaping station, passing through Teru 2. After concreting the form 14, the pusher 6 is moved to the first inch 4 of the transfer carriage 3, which transports the form 14 to the receiving conveyor 9 of the heat treatment chamber 8. The pusher b moves the form 14 to the chamber 8, simultaneously moving the row of the forms 14 that are It, over the length of the transport platform 15, at the same time, the under-mold 14 moves to the transfer trolley 11 of the heat chamber. At the same time, the mold 14 is fed to the return conveyor 10 of the cameo 8 and the mold 14 is heat-treated. The transfer carriage 3 with the mold 14 is moved to the device for stripping 13, and the transfer carriage 11, freeing it from the mold, is moved to the initial conveyor 10 of the heat treatment chamber 8 after the new mold. Stops with the shape of the front-end unit 13. Next, the carriage 3 moves to align path 5, on which Form 14 is located, with heat-treated products from the rails of the lifting and lowering frame 29 of the stripping unit 13, after which Form 14 is moved by the pusher 7 to the dismantling post. Next, the carriage 3 transfers the empty mold 14 to the molding station I. The concrete mixture is placed in the mold 14, and the cycle is repeated "After the mold 14, which is heat generating, enters the rails of the lifting frame 29, which is in an elevated condition, the composite guide beams 24 of the hydraulic cylinder 25 are driven to a horizontal position with their spring-loaded supports 27. The mold 14 on the one hand is pressed by the movable wall 31, and on the other side by the hydraulic stops 26. At the same time, the unscrewing of the wines occurs 18, 21 by wrenches 32. After loosening, wrenches 32 are retracted from screws 21 by hydraulic actuator 33. Lifting-lowering frame 29 is lowered by means of hydraulic actuator 30 from forward platform 15, while form 14 rests on composite beams-guides 24 roller rollers 17. Close the locks 19, located on the wall 31, open the locks 19, located. EU at the ends between the extreme and subsequent separation forming boards 16. The lever-hydraulic mechanism 23 expands the molding boards 16 and the released product is removed by a lifting mechanism, such as a bridge crane (not shown in the figures). Next, the shields 16 shift, close the locks 19 of the shield of the first compartment, open the locks 19 of the shield of the second compartment

The next product is dismantled, etc.

At the end of the cutting, cleaning, lubrication of the ishtov compartments and installation of fittings in them occurs.

Form 14 is locked. The lifting and lowering frame 29 is produced with the transport platform 15 and the mold 14 is mounted onto the platform 15. The nutrunners 32 are turned on, which tighten and tighten screws 18 and 21 on the clamps 20 of the transport platform 15.

The drive 28 spring-loaded supports 27 are removed, and the composite beams guides 24 by the hydraulic cylinder 25 are rotated 90 to pass the form 14 on the transfer to the carriage 3.
