SU944927A1 - Apparatus for compacting concrete mix in form - Google Patents

Description

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

A device for compaction of concrete mixes in a mold is known, which contains a frame with an ELM annular protrusion and a spring-loaded working body that, with a protrusion, is connected to a pressure source, forms a force chamber 1.

The closest technical solution to the present invention is a device for compacting concrete mixtures in a mold, comprising a frame with an annular protrusion and a spring-loaded working body forming a force chamber with the protrusion, and a valve in the form of an elastic cuff fixed to the surface of the annular protrusion and placed inside the anvil supported on the frame by means of elastic supports 2.

A disadvantage of the prior art devices is the inconvenience of service, poor quality of the products and unreliability.

The purpose of the invention is to improve serviceability, quality, and reliability.

This goal is achieved by the device for compacting a concrete mix in a mold containing a working body with a hammer mounted on a fixed frame by means of elastic supports and in contact with the latter anvil spring-loaded relative to the fixed frame and the exciter of oscillations in the form of a working KciMepy elastic cuff connected to source of pressure, provided with additional impactors and elastic cuffs located symmetrically with the core, and the anvil is made with projections contacting and strikers and podpru15 zhinena relative to the working body, and the main and additional elastic sleeve disposed between the fixed frame and the anvil.

FIG. 1 shows the device on

20 beginning of the working cycle, longitudinal section; in fig. 2 - the same, at the time of the strike by the strikers on the anvil; in fig. 3 - the device at the beginning of the operating cycle, transverse 25 times res.

A device for compacting a concrete mix in a mold contains a working body 3 with shock pins 4 and an anvil 5 mounted on a fixed frame 1 with elastic supports 2, made with protrusions 6 and spring-loaded elements 7 relative to the working body 3 and elements 8 relatively fixed frame 1. Anvil 5 by means of protrusions 6. contacts with the impactors 4. The oscillator is made in the form of elastic cuffs 10 forming the force chambers 9; in addition, elastic cuffs are located between the fixed frame 1 and the anvil 5 and provide wives limiters 11 move. The force chambers 9 are communicated with a common channel 12 by means of a hose 13 with a valve 14 mounted therein with a pressure source. In addition to the common crane 14, taps 15 are installed at the outlets to each power chamber 9, which serve to adjust their operation by throttling. The device works as follows. A form with a concrete mixture is mounted on the working body 3 and secured. Then compressed air is supplied through the common channel 12 into the force chambers 9. Under the action of the pressure created in the force chambers, the anvil 5 begins to rise and the protrusions 6 contact with the strikers 4, as a result of which a blow is transmitted to the working body 3 and through it to the mold. When climbing to): oval 5 elastic cuffs 10, unclenched, initially fit snugly to the bottom surface of the anvil 5, but since the course of the elastic cuffs is limited by the stroke limiter 11 of the stroke, as the anvil continues to lift, the elastic cuffs detach from it, the force chambers 99 unseal and anvil under the influence of its weight, after striking the strikers 4, it is lowered down, with the help of elastic supports 8 occupies a constructively defined position in which elastic cuffs 10 are pressed against its lower surface again, and Thus, the cycle is repeated. The use of the proposed device will make it possible to form heavy and long products. The invention is a device for compacting a concrete mix in a mold containing a working body with a hammer mounted on a fixed frame by means of elastic supports and an anvil in contact with the latter spring-loaded relative to the fixed frame and an exciter in the form of an elastic cuff forming a working chamber, characterized by that, for the purpose of ease of maintenance, improvement of quality and reliability, it is supplied with additional tel drummers and elastic cuffs arranged with it is symmetrically basic, with the anvil B1L1filled with protrusions in contact with the strikers and spring-loaded relative to the working member, while the main and additional elastic cuffs are located between the fixed frame and the anvil.
