Description

one

This invention relates to devices for the manufacture of precast concrete and reinforced concrete products.

A device for molding reinforced concrete casings of a double curvature is known, comprising a self-propelled carriage, on the frame of which a feeder is installed and a distribution hopper with dampers located beneath it, associated with a vertical displacement mechanism and a vibrating sheet 1.

The closest technical solution to the invention is a device for forming curved shell panels containing a self-propelled portal with a vertically movable transfer hopper with a flap mounted on it, the rollers of which are placed in the guides of the portal, and a vibrating profiler, the latter and the distributing hopper supported by rollers on guide forms 2.

The disadvantages of these devices are the inconvenience of their operation and the low quality of the molded products.

The aim of the invention is to improve the usability of the device and the quality of molded products.

This goal is achieved by the fact that the device for forming curvilinear

sheath panels containing a self-passage portal with mounted vertical movable transfer bunker with a flap, rollers of which are placed in the guides of the portal, equipped with a profile profiler, the latter and the transfer bunker supported by rollers on guide forms, equipped with an ex-movement of vertical movements and replaced with a hotspot and hobo - a storage device placed above the dispensing bin, the vibrating pattern-profiler and the flap being fixed respectively in its lower part. on the front and rear along the walls.

In addition, distributing n accumulative bunkers are equipped with frames in the upper connected and upper crossbars of the racks, and the frame of the storage hopper is located inside the distributing frame

bunker and in contact with its racks and

upper cross-pieces respectively

pomopi rollers n stops.

FIG. Figure 1 shows schematically a device for forming cladding panels, front view; pas figs. 2 - view A of FIG. one.

A device for forming curved shell panels consists of a self-propelled gantry 1 mounted on a rail over form 2, on which storage hoppers 3 and distribution hopper 4 are mounted one above the other, and in the lower part of the latter on the front and rear walls are fixed along the way accordingly, vibrating pattern profiler 5 and damper 6.

The storage hopper 3 is provided with a frame in the form of connected upper 7 and lower 8 crossbars of the uprights 9, on which rollers 10 are attached, which are in contact with the uprights 11 of the frame of the transfer bunker 4. The uprights 11 are connected by horizontal upper 12 and lower 13 crossbars. The upper cross member 7 mounted on the cable 14 mechanism 15 vertical displacement. The hopper frame 3 is placed inside the frame of the hopper 4, and the upper horizontal crossbars 12 of the bunker 4 are supported on the upper horizontal crossbars 7 by means of the Sh-bar, the latter contacting the rollers 18 of the gantry 18 equipped with a drive 19 horizontal displacements.

The distributing hopper 4 and the vibrating pattern profil 5 in the working position are supported by means of the rollers 20 on the guides 21 of the shape 2. The vibrating pattern of the profiler 5 is made of sections 22, on which are mounted the oscillation pathogen 23 oscillations.

On the rack 11 of the frame of the transfer hopper 4 installed limit switches 24 and 25, interacting with the stop 26 of the rack 9 of the frame of the hopper drive 3.

A device for forming curved panels operates as follows.

After loading the concrete mixture into the bunker 3, the self-propelled gantry 1 drives the horizontal movement 19 onto the edge of the mold 2, then lowers the dispensing bunker 4 together with the vibrating profiler 5 to the working position, while using the rollers 20 on the rails 21 forms 2. After that, the excitation pathogens turn on 23 oscillations, open the gate of the storage hopper 3 and turn on the operating speed of the drive 19 of the horizontal movements of the portal, which begins to move along the form 2, while the vibrating pattern-profiler y compacts and smooths the concrete mix to be laid in form 2 with a transfer bin 4.

When the portal 1 moves along the mold 2, the vibrating pattern-profiler 5 and the dispensing hopper 4 supported by the rollers 20 on the guides 21 of the mold 2 repeat the configuration of the molded product within the limits specified by the limit switches 24 and 25, which, when closed, serve

commands to turn on the mechanism 15 vertical movements, moving through the cable 14 to the hopper drive 3, providing a stable size of the gap between the last and the dispensing hopper 4, thereby preventing the separation of the concrete mix.

The thickness of the concrete layer to be laid is set by the flap 6.
