(54) FLOW LINE FOR THE MANUFACTURE OF REINFORCED CONCRETE PRODUCTS

The invention relates to manufacturing equipment for the manufacture of precast concrete in enterprises of the building industry, in particular, for conveyor production of ribbed products such as slabs, trays, etc., molded in forms of various widths.

The known production line for the manufacture of reinforced concrete products, containing a demolding station with catcher stands having base surfaces, posts of cuts and mold lubrication, rebar placement, concrete mix compaction with vibrating drives, as well as feed and return conveyors with supporting and side rollers for transporting forms l.

This line does not allow to make products in forms of different widths. installing them on a conveyor belt with the help of ordinary rack stands is impossible, and regulation

the spacing between racks according to the width of the molds would require actuating devices. In addition, the device for adapting the shape to the vibrodrive was extruded in the form of a lifting-lowering plate. Therefore, for the pr / yo-uni form to the vibro-drive, to feed it to the parallel molding station, when forming the product in two steps, it is necessary to lower the vibrodrive into the socket, and during the molding it will firmly fix the base plate to ensure the normal operation of the vibrodrive. To do this, a lift and spacer devices that are easily clogged during molding are required.

The purpose of the invention is to increase the productivity of molding products of various sizes.

For this, rack-sided and side shreds are installed at the dismantling station on one side of the conveyor, the supporting rollers are turned in a horizontal plane, and the vibration drives are made with horizontal grooves and equipped with wedges in a vertical plane. In addition, the base surfaces of the rack-loops are removed from the axis of the conveyor by half the width of the solid form.

Claims (1)

The proposed design allows you to quickly install on the conveyor the shape of products of several sizes with a crane without the HELP of rigging, which leads to lower labor costs and increased productivity. FIG. 1 shows a flow line, a plan view; in fig. 2 — a form removal station, a plan view, in FIG. 3 is a view along arrow A in FIG. 2; in fig. 4 — conveyor carriage; FIGS. 5 and 6 — molding station (facade and plan). Line in the plan has a U-shaped scheme and includes six technological posts; post 1 - stripping and cleaning forms; post 2 - lubrication of forms and installation of fittings; posts 3 and 4 - molding products; post - 5 you hold the molded products; post 6 removal of forms by crane. Posts 1, 2 and 3 are united by a feed conveyor 7 consisting of non-driven support 8, side (baffle) 9 and rotated rollers 10, guides 11 with carriage 12, winches 13, branch 14 and end 15 blocks. Stands 16, having base surfaces 17, are installed on post 1, the distance from them to the axis of the conveyor 7 being equal to half the width of the smallest form. The carriage 12 is equipped with pivoting stops 18 and a stop roller 19 having a normally raised position. Posts 5.4 and 6 are joined by a conveyor 20, the device of which is similar to the feeding conveyor 7, the molds 21 for moving along the rollers 8 and the conveyors 20 are provided with longitudinal beams 22, the distance between them being equal to the conveyor track (the distance between the side rollers 9), and a crossbeam 23 for the stops 18 and 19 of the carriage 12. Between posts 3 and 4, the forms are transported by a trolley 24 driven by a winch 25. Each of the posts 3 to 4 has a vibrodrive 26 and pneumatic lifters with shock absorbers 27. The vibro drive 26 is mounted on the shock absorbers 28 and is soundproofed casing 29. The body 30 of the vibrodrive has a stop plane 31 and a horizontal cutout 32 for the passage of the transverse beam 33 of the mold 21 and the wedge 34, moved in the guides 3 5 with the help of levers 36 by means of pneumatic cylinders 37. The line is equipped with a control panel 38, two concrete pavers 39 , crane, equipment for cleaning and lubrication of molds, etc. The proposed line works as follows. The form 21 with the product is lowered by a crane to the post 1 of the demoulding so that its longitudinal side slides along the base surfaces 17 of the posts 16, and the distance between the longitudinal beam 22 of the form 21 and the side rollers 9 is minimal for the narrowest form, and the widest is the maximum. After removal of the product, the mold is cleaned, its sides are closed at post 1, and after completion of technological operations at other posts carried out simultaneously, include a winch 13, a conveyor 7, feeding the carriage 12 to the first post. During the reverse movement of the carriage 12, due to the stop 18, the stop roller 19, the molds from posts 1 and 2 are moved one step. In this case, the extreme shape moves on the turned rollers 10 not only in the longitudinal direction, but also in the transverse direction until the longitudinal beam 22 contacts the side rollers 9, and the stop roller 19 rolls along the transverse beam 23, as a result of which it is installed along the axis of the conveyor 7. at post 3, the form enters the bar 33 into the notch 32 of the vibrodrive 26 against the anvil with plane 31. The pneumatic lifts with shock absorbers 27 are automatically turned off, the form is exposed to them, then the pneumatic cylinder 37 is turned on, the wedge 34 is moved in the guides 35 and clamped The bar 33 on the housing 30. Then the concrete is laid by the concrete paver 39 and the edges of the product are formed. At the end of it, the carriage 24 is supplied to the post 3, the pneumatic cylinders 37 are switched, the wedges 34 are lowered, the air lifters 27 are turned off, the mold 21 sits on the carriage 24 and is transported to the post 4. Thanks to the side 32 open cutout in the vibrodrive 26, the form bar 33 passes freely into it Further, the operations are repeated. At station 4, a post-production, carpet molding and finishing of its surface is performed. After the carriage 24 goes to the post 3, the mold 21 at the post 4 is lowered onto the rollers 8 of the return conveyor 20, transporting the molds along which is similar to the conveyor 7. From post 6, the mold with the freshly formed product is transported by crane to the post of heat and moisture treatment. This is the end of the product manufacturing cycle. Claim 1.
