Technical Field

The utility model relates to a concrete processing technology field, in particular to mould platform vibrates self-compaction device.

Background

In the existing concrete prefabricated part production line, a large-scale die table is loaded on a vibrating table outside the production line through a lifting system, then the vibrating table utilizes a hydraulic clamp to clamp the large-scale die table, and concrete poured on the large-scale die table is vibrated, so that air bubbles in the concrete are discharged, and the compactness of the concrete is improved.

At present, in the existing mould table vibrating device, a vibrating motor vibrates a mould table through a magnetic base on the periphery below a motor mounting seat, vibration fluctuation is transmitted to concrete in a mould for preparing a prefabricated part from the mould table, the concrete just poured becomes dense, bubbles are upwards and naturally discharged, the rate of the cost of the part is reduced, the repair rate of the part is reduced, the yield of the part is improved, the production cost of the part is reduced, the labor intensity of workers is reduced, and the production mechanization level of a fixed mould table is improved;

however, in the implementation process of the above technical scheme, at least the following technical problems are found:

2. the corresponding vibration amplitude cannot be selected according to the type of concrete: when different concretes are vibrated, the required force and amplitude are different (for example, for a concrete with low viscosity, the air in the concrete can float out when slightly shaking, and in the same way, the air in the concrete is lower than that in a concrete with high viscosity, and the air in the concrete is easily subjected to larger resistance in the process of moving upwards, so that the air is discharged only by using vibration with large amplitude); the magnitude of the elastic force of the spring is related to the magnitude of the force applied to the spring; the spring force is related to how tightly the spring is compressed; therefore, the longer the spring is, the more the spring can be compressed, and the larger the elastic force can be, therefore, a die table vibration self-compacting device is provided.
