Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: the external coil power of 1-, 2-coil, 3-coil rack, 4-shell, 5-energy-storaging spring, 6-rapping rod, 7-insulator foot, 8-locating sleeve, 9-keeps circle, 10-bolt, 11-cathode suspended bar, 12-dust excluding plate, 13-vibrator base.
The specific embodiment
As shown in Figure 1, the present invention includes shell 4, energy-storaging spring 5, coil 2, rapping rod 6 forms, shell 4 is connected with vibrator base 13 by bolt 10, shell 4 internal coil skeletons 3, coil rack 3 encloses 9 by maintenance and is fixed in shell 4, coil 2 is wrapped on coil rack 3, in coil rack 3, be provided with rapping rod 6 and energy-storaging spring 5, the upper end of energy-storaging spring 5 is fixed on shell 4 inwall tops, the lower end of energy-storaging spring 5 is connected with the upper end of rapping rod 6, rapping rod 6 belows are disposed with insulator foot 7 and locating sleeve 8, insulator foot 7 is fixedly connected with locating sleeve 8.Dust excluding plate 12 is fixed on vibrator base 13 by bolt 10, and dust excluding plate 12 both sides are connected by bolt 10 with shell 4.
Rapping rod 6 hoisting depths are 300-320mm, the little frame of negative electrode that the 15M of take is high is example, when the elevated height of top electromagnetic vibratory hammer device rapping rod is 300mm, more than minimum vibration acceleration value can reach 100g, the relative root mean square of its acceleration profile is 0.2, be less than 0.4 industry, can thoroughly solve conventional side arm sinker acceleration profile inhomogeneous and due to problems such as the excessive failure by shear causing of local vibration acceleration, distortion, short-term, off-axises.Energy-storaging spring 5 can be that at least one spring forms.Locating sleeve 8 is rubber locating sleeve.
As shown in Figure 1, when vibrator coil 2 passes to after external coil power 1, produce electromagnetic induction power, rapping rod 6 is promoted, while compress energy storage spring 5, make energy-storaging spring 5 storage power, while reaching a certain height, coil blackout, magnetic field disappears, the free-falling under Action of Gravity Field of rapping rod, clash into vibrating rod, by rapping rod 6, rapping power is delivered to electric cleaner inner cathode suspending rod 11, below by rapping rod 6, be provided with insulator foot 7 and locating sleeve 8, locating sleeve 8 is arranged on cathode suspended bar 11 upper ends with nested form, now due under the effect at energy-storaging spring 5, rapping rod 6 is accelerated by bounce-back rapidly, thereby obtain larger buckles, obtained larger ramping effect, finally reach the object of vibration dust-cleaning.
