Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
A kind of electromagnetic piling machine, comprising: fixed disk 7, is placed in the electromagnet 4 in fixed disk 7, and dynamic disk 9, is located at the closing coil 3 dynamic disk 9 also corresponding to electromagnet 4, is formed at the electromagnetic hammer 2 on dynamic disk 9.When passing to the alternating current of setpoint frequency to the electromagnet 4 in fixed disk 7, electromagnet 4 magnetic pole now in fixed disk 7 and the large young pathbreaker in magnetic field are cyclically-varying, closing coil 3 meeting in movable disc 9 is change of flux according to electromagnet 4 changes of magnetic field in fixed disk 7, from Lenz's law, ring current can be produced in coil and form magnetic field to hinder this change.When electromagnet 4 magnetic field strengthens, closing coil 3 will produce the magnetic field relative with electromagnet 4 homopolarity, therefore closing coil 3 can promote electromagnetic hammer 2 principle fixed disk 7 moves; When electromagnet 4 field weakening, closing coil 3 will produce the magnetic field relative with electromagnet 4 heteropole, and produce mutual attractive force, then electromagnetic hammer 2 is pulled to fixed disk 7 by closing coil 3.Piling process can under modulated electric current drives and so forth, and by the modulation of electric current, can to drive piles dynamics, frequency and movement travel by pre-set electromagnetic hammer 2.In order to avoid interference, wherein fixed disk 7, dynamic disk 9, closing coil 3 adopt nonferromugnetic material, and closing coil 3 is electric conductors.
A kind of electromagnetic piling machine, also comprises: the housing 1 of fixing fixed disk 7, is provided with protruding 8 inside housing 1, be provided with the buffer 6 on protruding 8.The object arranging buffer 6 is, prevents fortuitous event down moving disc 9 and electromagnetic hammer 2 collision shell out of control and damages.Preferred as one, buffer composition has the spring 601 be installed in projection, lays the steel ring 602 of spring 601; It act as, prevent fixed disk and pile hammer out of control, pile hammer and fixed disk can not impact shell, and falling impacts shell top and the bottom housing when avoiding power cut-off.
Electromagnetic hammer 2 and housing 1 are equipped with spline bearing 5 in contact position; Fixed disk 7 is provided with the first through hole placing electromagnet 4, and dynamic disk 9 is provided with corresponding to the first through hole and places the second through hole of closing coil 3.The iron core in the magnetic field that electric current produces in intensifier coil is provided with in closing coil 3.
When the electromagnet 4 in fixed disk 7 produce magnetic pole and magnetic field intensity all do the magnetic field that rule changes time, during increase when magnetic flux through closing coil 3 in dynamic disk 9 known by Lenz's law, closing coil 3 will drive dynamic disk 9 to the direction motion making its magnetic flux reduce, namely move to the direction away from fixed disk 7, therefore under the magnetic fields doing rule change, drive fixed disk 7 is done piston movement by the closing coil 3 be fixed on dynamic disk 9, and then drive electromagnetic hammer 2 to do piston movement, realize the principle of pile driver.
The present invention proposes a kind of take electric energy as the pile driver of the energy, electromagnet 4 is placed in fixed disk 7, closing coil 3 is placed in dynamic disk 9, electromagnetic hammer 2 is placed on dynamic disk 9, the transmission of dynamic disk 9 is realized according to Lenz's law, piling process can under modulated electric current drives back and forth, and by the modulation of electric current, can to drive piles dynamics, frequency and movement travel by pre-set electromagnetic hammer 2; The projection 8 of housing 1 inside combines with buffer 6 and prevents fortuitous event down moving disc 9 and electromagnetic hammer 2 collision shell out of control and damage; The present invention take electric energy as the energy, and cleanliness without any pollution, significantly reduces noise, and piling dynamics, frequency, stroke are easy to control, and effectively can reduce wearing and tearing, power, tonnage can freely customize according to demand.
More than show and describe general principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
