Description

The invention relates to the building materials industry and can be used in factories for the production of cellular concrete building products.

Figure 1 shows a General view of the installation; figure 2 is the same in plan; in Fig.3 - section aa in Fig.2.

The installation includes a removable permanent one-piece rig 1 mounted on a pallet-trolley 2, placed on a lift-lowering rail track 3. on a portal frame 4 underneath the trimmer 1 with vertical movement. with a cutting lattice 7 located inside the bosnestki 1 in its bottom part.

Inside the rigging 1 in its upper zone, on the rods 8 of the frame 4, a frame limiter 9 is mounted.

In the guide bushings 10 of the traverse 5, rods 11 are placed rigidly connected to the side gear 1. The traverse 5 is driven by a power cylinder 12 through the cable assembly system 13.

On frame 1, by means of a suspension frame 15 is repaired with cutting strings 16, each of which is placed in the initial position before molding under the corresponding transverse partition of the grating 7.

In addition, the flight 1 is equipped with vibrators 17.

The horizontal movement of the frame 15 is driven by a power cylinder 18.

The weight of the traverse 5 and the lattice 7 is balanced by the counterweights 19 and 20,

The raising and lowering of the rail tracks 3 is carried out by the drive 21.

Suspension 14 is made in the form of articulated lever systems, each of which with

stands out from the cross-shaped rods 22, the lower ends of which are pivotally connected to the frame 15, and the upper ends with the shoulders of the corresponding swing arm 23, the swing axis 24 of which is rigidly fixed to the side gear 1.

The installation is located under the dispensing hopper 25.

The installation works as follows.

On rail tracks 26, a pallet-trolley 2 is fed into the installation area, onto which, by means of a drive 12, traverses 5 lower the tool 1 together with the grill 7 and the cutting frame 15. In this case, before the first molding, the grill 7 is placed in a raised above the pallet-trolley 2 position, after which the concrete mixture is poured from the hopper 25 into the mold formed by the rigging 1 and the trolley 1. At the same time, the vibrators 17 are averaged. Immediately upon completion of pouring the mixture into the mold, the grate 7 is lowered (loaded) until it contacts the forming surface of the trolley 2,

After the shutter speed necessary to achieve plastic strength, turning on the drive 12 carries out the lifting, traverse 5, as a result of which only the grating 7, which is lifted, is initially lifted. the torus cuts the concrete array vertically in the lower zone of the rigging 1, and during the further lifting of the beam 5, the protrusions of the rods 11 abut against the beam and, as a result, the rigging 1 and the grill 7 rise simultaneously. As a result of lifting the rigging 1, the formed column is removed array, and as a result of lifting the lattice 7 simultaneously with the stripping, there is a further vertical cutting of the array,

In the process of lifting the rigging 1 and the grill 7, the detachment of the concrete mass from the pallet-trolley is prevented by its own weight, the mass of which exceeds the total lifting forces of the rigging 1 and cutting by the grill 7, and also by a frame limiter 9 located in the thickness of the concrete mass in its upper part. At the end of the lifting of the flight rig. 1, together with the grill 7, the horizontal drive 18 of the frame 15 is turned on, by means of the cutting strings 16 which the array is cut horizontally and thus the array is divided into separate blocks (products). After horizontal cutting, the rail tracks 3 together with the pallet trolley 2 and the cut blocks lying on it are lowered and after a complete stop, the trolley 2 with blocks is transferred to the rail and then

to the next technological stations, and the next pallet-car 2 is fed into the installation zone, which then rises together with the rail 3 to the initial position before molding.

0 After that, by turning on the drive 12, the tooling 1 and the grate 7 are lowered together with the rest of the concrete mass in the grating cells and above it from the previous molding. Since the remainder of the concrete mass appears inside the board equipment5, the grate 7, unlike the first molding, is lowered until it comes into contact with the pallet trolley 2. After this, concrete (pouring) from the hopper 25 through the throat of the frame limiter 9

0, the mixture is fed into the mold formed by the rigging 1 and the pallet-trolley 2 and the cycle of work is repeated.

The detachment of the concrete mass from the pallet during the lifting of the rigging and from the influence of the cutting force developed by the grill 7, on the one hand, is prevented by the weight of the mass itself, whose mass is obviously greater than the total lifting and cutting forces, and, on the other hand, by tearing
