SU1351793A1 - Arrangement for stowing and compacting concrete mixes - Google Patents

Abstract

The invention is intended for laying and compacting concrete mixtures. The goal is ease of use. The device for laying and sizing concrete mixes contains a portal 1, a dispensing hopper 4 with an elastic suspension 3, a calibrating device 6 and a vibrating feeder 7 located in the lower part of the bunker. It is equipped with a mechanism of vertical displacement 2 vibratory feeders 7, to which the fairings 8 and protective tubes 9 are rigidly attached. Because of this, when the device is inoperative, they are a shutter. When dispensing the concrete mix, the vibro-feed feeders 7 are raised to the required height by the mechanism of vertical movements 2 and the pre-compacted mix is dispensed into the mold. The consumption of the mixture is determined by the lifting height of the vibratory feeders. 3 il. (L with sd |; about 00

Description

one

The invention relates to the production of concrete and reinforced concrete products.

The aim of the invention is the convenience of operation.

Fig. 1 schematically shows a device for laying and compacting concrete mixtures in an operational state; in figure 2 - the same, with closed feeder (non-working, for example, transport, position); - in fig - the cut A-A in figure 2.

The device for laying and compacting concrete mixes contains a self-propelled gantry f on which is installed, a mechanism of 2 vertical movements, an elastic hopper 3 is attached to a bunker 4, which has 5 oscillation pathogens located on the front and rear walls and calibrating devices 6, Inside the bunker at the bottom vibrated are located: feeders 7 with flaps 8 and protective tubes 9.

The device works as follows.

The hopper 4 is filled with a concrete mix (the vibratory feeders 7 are lowered). The portal moves to the form. The dispensing window of the hopper 3 is installed above the form. The exciters 5 oscillations and vibratory feeders 7 are driven, which are raised to the required height by the mechanism 2 vertical movements. The resistance to raising the vibrating units of the feeders 7 is significantly reduced due to their fluctuations in the operation of the exciters 5 oscillations and the fairings 8. The mixture in the hopper 4 is diluted and pre-compacted. Portal I moves along the form, the mixture in three streams evenly fills it. The oscillations from the exciter 5 oscillations are transmitted to the calibrating devices 6s, which simultaneously calibrate the mixture and compaction

nuty her. After the passage along the entire mold. The hopper 4 is emptied, the vibrating pulleys 7 are turned off, the oscillators have 5 oscillations, the vertical movement mechanism 2 lowers the vibrating and rotary feeders, closing the dispensing box of the bunker 4 completely. In the case of filling several forms from one bunker before the completion of filling the first form of the mechanism of 3 vertical movements lowers the vibrating ones. the feeders 7 to the dispensing window, the supply of the concrete mixture is stopped, the vibrating rotors are turned off,

lowering feeders contributes to the flow of the concrete mix, which carries them to the bottom a

The mechanism of vertical displacement 20 scientific research institutes can carry out during the laying of mixtures the regulation of the supply of concrete mix. The workflow of laying and compacting the concrete mix is provided in both directions of movement.
