Description

The invention relates to equipment for the production of building products from hardening mixtures, in particular to cassette installations for the production of flat plates.

The purpose of the invention is to intensify the vibration compaction of a concrete mix by creating a horizontally directed vibration.

FIG. 1 shows the installation, view from the end, in FIG. 2 - the same, with closed sides; in fig. 3 is a section A-A in FIG. 2

The installation consists of hinged 2 hinged sides 2 and interchangeable carriages 3 with dividing walls 4, each with a carriage mounted with the possibility of movement between the boards for passage as it moves in conveyor production. The forming sheets 5 are elastically fixed on the folding sides, on each of which (Fig. 3) a longitudinally rigid strip 6 is horizontally fixed with an opening 7 on one of its ends. In the openings 7 mounted unbalanced vibration exciter 8, which are made outside the ends of the 9 forming sheets. Torque 11 of the torque moment is fixed on axis 10 of the exciters, and synchronizer 12 is fixed on the end of the separation wall 4 of each trolley form with the possibility of free rotation, which engages with the drivers 11 when the sides are closed.

The installation is equipped with a mechanism. coupling strips 6 s. dividing wall 4, which is made in the form of dividing wall 4 of grippers 13 (of each trolley-form) fixed at the ends, and power lugs 14 that respond in shape to grips for their engagement. A pulley is attached to the axis of one of the unbalanced vibration exciter (Figs. 1 and 3), which is connected with a drive 15 by means of a strap. two cavities 18 for forming articles. .

The installation works as follows.

In conveyor production, one of the trolley forms is placed

5 between the sides 2 (Fig. 1). Then turn on the actuators 16, which by turning the sides press the forming sheets 5 to the frames 17 (Fig. 2 and 3), while the leads 11 of both

 vibration exciters 8 will enter into engagement with synchronizers 12, which will ensure their synchronous operation in one phase. After that, concrete cavity is placed in cavity 18. One 5 temporarily turn on the actuator 15, which transmits rotation to the exciters 8, while the latter, by placing them in the openings 7, transmit longitudinal oscillations to long 20-rigid planks 6, which, thanks to the hard coupling, captured 13 and the projections 14 with the partition wall 4 thanks to their tight bond with the mold

25 sheets 5 provide them (forming sheets and dividing wall) horizontal oscillation in the same phase and with the same amplitude. As a result of the oscillations of all the walls

30 cavities 18 in one phase provide Intensive compaction of the mixture, which improves productivity by reducing the time required for the mixture.

35 After the completion of the molding of the construction products by means of the actuators 16, the beads 2 are retracted from the frames 17, as a result of which the leashes 11 break from the engagement with the synchronizer 12, and the projections 14 come out of the grips 13, allowing To the sides of the aisle zone, move the trolley form along the conveyor line to the next post, namely to the post of heat treatment. On the vacated space between the forming sheets, the next form-trolley is installed and the process is repeated.

Thus, the proposed installation provides the oscillation of all the molding surfaces in one phase, which increases the intensity of the mixture compaction in the installation from shift 55

dividing wall.
