Description
Technical field
The utility model relates to a kind of cement products process units, specifically a kind of three-dimensional variable frequency vibrational system.
Background technology
In the production process of concrete or cement products, need to reasonably vibrate to the cement or the concrete that pour in mould, its objective is and make concrete or cement material grain under self-gravity action, enrich voluntarily the gap of material intergranular, get rid of inner air, make the closely knit moulding of concrete or cement products, and ensure concrete or cement products smooth surface, smooth.The vibrational system that existing large plate-type concrete or cement products adopt, structure is comparatively simple, adopt the bottom that is arranged on mould by equidirectional multiple vibrating motors, and adopt same Frequency Converter Control vibration frequency, vibrate with the cement in mould or concrete.But the vibrating motor quantity that this vibrational system needs is more, and vibration frequency and the direction of vibration of generation are single, and overall vibration effect is poor, thereby affects the quality of concrete or cement products.
Utility model content
The purpose of this utility model is just to provide a kind of three-dimensional variable frequency vibrational system, to solve existing vibrational system because of vibration frequency and the single poor problem of vibrating effect that causes of direction of vibration.
The utility model is achieved in that a kind of three-dimensional variable frequency vibrational system, includes:
Shake table, for placing splendid attire cement or concrete mould, is provided with some elastic supports in its lower end;
Link, for being fixed on described shake table by the mould being placed on described shake table;
Oscillation crosswise motor, is fixed on the bottom surface of described shake table, carries out in the horizontal direction oscillation crosswise for controlling described shake table;
Extensional vibration motor, is fixed on the bottom surface of described shake table, carries out in the horizontal direction extensional vibration for controlling described shake table; And
Frequency converter, for carrying out respectively VFC to described oscillation crosswise motor and described extensional vibration motor.
Described oscillation crosswise motor has two, and symmetry is arranged on the bottom surface of described shake table.
Described extensional vibration motor has two, and symmetry shape is arranged on the bottom surface of described shake table, and is positioned at the inner side of two described oscillation crosswise motors.
Described elastic support comprises that lower margin props up piece, bolt and spring; Described bolt, through described shake table and described spring, is connected to described lower margin and props up on piece.
The utility model is by the oscillation crosswise motor on transverse plane under shake table and extensional vibration motor, realize the vibration of the horizontal and vertical both direction of mould, and the vibration that produces above-below direction (with shake table under transverse plane vertical direction) by elastic support, to realize the three-dimensional vibrating of mould.Controlled respectively the rotating speed of oscillation crosswise motor and extensional vibration motor by two different frequency converters simultaneously, realize the vibration of different frequency, make vibration force can Transmit evenly to the every nook and cranny of mould, make to greatest extent bubble separation in concrete out, and the uniform particles in concrete is disperseed, make in the short period of time the closely knit moulding of concrete and cement products.The utility model can make mould produce in horizontal, longitudinal and upper and lower three directions to vibrate, improved vibrating effect, reduced the quantity of vibrating motor, thereby reduced energy resource consumption.
