Description
Technical field
The present invention relates to construction field of tool, are to be related to a kind of concrete vibrator particularly.
Background technique
During concreting, it usually needs vibrated using concrete vibrator to main body is poured, to mention
Height pours the uniformity of main body each section, and eliminates its air entrapment, prevents hollowing phenomenon.However current vibrator vibrates
Component is a stub, has the rotation swing rod rotated by external driven by quill shaft inside stub, which matches
Weight roller provides a centrifugal force to the stub, so that the stub rotational vibration, vibrates to surrounding concrete.
However there is various disadvantages for this kind of vibrator；Such as, flexible axle is driven by driving sources such as motor or internal combustion engines, is made an uproar
Sound is larger；The system bulk formed by driving source, flexible axle, vibrating head is numerous and jumbled, not portable；Process of the flexible axle in transmitting mechanical energy
In, transmission efficiency is lower, and energy loss is larger；Also, this kind vibrates the vibrator of rod type, only in vibrating head circumferential direction near zone
Effect of significantly vibrating is formed, and in the axial direction, effect of not vibrating substantially, it is therefore desirable to more shift vibrating head
Position, could to pour main body carry out it is good vibrate, operating efficiency is lower.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of electromagnetism concrete vibrator, the vibrator structure letter
Single, energy consumption, noise are lower, and vibration efficiency with higher.
The technical solution adopted by the present invention to solve the technical problems is: the electromagnetism concrete vibrator includes at least two
The upper end of the bar disposed in parallel that vibrates, the bar that vibrates is fixed on the base by elastic construction, so that the bar that respectively vibrates can be mutual
It is close and separate；The bar that vibrates includes straight-bar, and ball of the, centre of sphere equally distributed along straight-bar on the straight-bar axis
Body；The electromagnet extended along straight-bar is equipped with inside the straight-bar, each electromagnet is connected in parallel to the power module in the pedestal,
The power module provides AC excitation electric current for each electromagnet.
Preferably, the elastic construction includes that one end connects the pedestal, the spring for the bar that vibrates described in other end connection,
Or resilient metal strip.
Preferably, the power module includes power conditioning module, the AC excitation can be adjusted according to field demand
The size of electric current, to realize the adjusting of output power.
Preferably, the power module includes frequency-variable module, to realize that the frequency of the AC excitation electric current is adjusted；From
And according to different operating conditions, it is adjusted to optimum vibration frequency, to optimize effect of vibrating.
The beneficial effects of the present invention are: after the bar that vibrates is downwardly into concreting main body, to each bar that vibrates
Interior electromagnet excitation, then the bar that respectively vibrates attracts each other under magneticaction, and magnetic attraction is fluctuated with alternating current, thus makes each vibration
The vibration of stamp stem continuous transverse；During this, the sphere that vibrates on bar forms inclined thrust to concrete, i.e., have simultaneously laterally and
Longitudinal component can widely be vibrated effect in all directions to pouring main body output vibration wave with forming sphere of action, thus
It can be obtained good effect of vibrating without repeatedly shifting the bar that vibrates, largely improve vibration efficiency.
Detailed description of the invention
Fig. 1 is the schematic diagram of the embodiment one of this electromagnetism concrete vibrator.
Fig. 2 is the schematic diagram of the embodiment two of this electromagnetism concrete vibrator.
Fig. 3 is the schematic diagram of the embodiment three of this electromagnetism concrete vibrator.
Specific embodiment
Embodiment one:
In embodiment one shown in Fig. 1, which includes two bars 1 disposed in parallel that vibrate, each described
Vibrating, to pass through independent spring 31 respectively fixed on the base 2 for the upper end of bar 1, so that the bar 1 that respectively vibrates can be close to each other and separate；
The bar 1 that vibrates includes straight-bar 11, and sphere 4 of the equally distributed, centre of sphere on the straight-bar axis along straight-bar 11；It is described
The electromagnet (not shown) extended along straight-bar is equipped with inside straight-bar 11, each electromagnet is connected in parallel to the power supply in the pedestal 2
Module, the power module provide AC excitation electric current for each electromagnet.
Above-mentioned electromagnetism concrete vibrator, after the bar 1 that vibrates is downwardly into concreting main body, to each bar that vibrates
Interior electromagnet excitation, then the bar that respectively vibrates attracts each other under magneticaction, and magnetic attraction is fluctuated with alternating current, thus makes each vibration
The vibration of stamp stem continuous transverse；During this, the sphere 4 to vibrate on bar forms inclined thrust to concrete, as shown by the arrows in Figure 1
Meaning has horizontal and vertical component simultaneously, can be in all directions to main body output vibration wave is poured, to form sphere of action
Effect of widely vibrating largely is improved because can be obtained good effect of vibrating without repeatedly shifting the bar that vibrates
Vibration efficiency.
In addition, the power module may include a power conditioning module, encouraged with adjusting the exchange according to field demand
The size of magnetoelectricity stream, to realize the adjusting of output power.The power module can also include frequency-variable module, to realize the friendship
The frequency for flowing exciting current is adjusted；To be adjusted to optimum vibration frequency according to different operating conditions, to optimize effect of vibrating.
Embodiment two:
In embodiment two shown in Fig. 2, the difference is that, the elastic construction is that one end connects pedestal 2 with embodiment one,
Vibrate the resilient metal strip 32 of bar 1 described in other end connection.
Embodiment three:
For embodiment three shown in Fig. 3, unlike embodiment two, the bar 1 that vibrates is with three；It needs to illustrate
It is that this three bars that vibrate should be arranged on three inclines of a regular triangular prism, thus provides vibration wave to more directions.And
The radical by the bar 1 that vibrates such as is needed to be arranged some more, such as 4 or more, then the bar 1 that should also make respectively to vibrate is arranged at one just
On each incline of polygon prism, symmetrically to export vibration wave, and the balance of whole device is kept.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
