Frictional force between iron core 3 and guideway 5.
Coil 7 is wound on the outer layer of guideway 5, axially aligned, the need according to the height, i.e. iron core displacement of steel cylinder inner chamber
Will, provided with L (1), L (2) ..., L (n-1), the common n groups coils of L (n).
Hall sensor 8 is located at the inner side of guideway 5 of side, iron core 3 and the inwall gap location of steel cylinder 1, is opened from inner chamber bottom
Begin, axially spaced distribution, the length of the length and coil 7 of its spacing and iron core 3 is approached or equal, provided with H (0), H (1),
H (2) ..., H (n-1), the common n+1 sensor of H (n), for detecting magnetic core position, the sensor internal be integrated with amplification electricity
Road, can feed back to signal corresponding coil solid-state relay, the break-make and sense of current of control coil 7.
The Portable ground rod installs motive power machine device operation logic:
Originally when iron core 3 is located at 1 inner chamber lower end of steel cylinder, the H (0) among Hall sensor 8 is located at below the S ends of iron core 3
(If it is positive signal that Hall sensor, which senses the signal that N pole fields are exported, it is negative to sense the signal that S pole fields are exported
Signal), H (0) detects negative signal and the input R of rest-set flip-flop is fed back to by becoming low level after amplifying circuit, such as attached
Shown in Fig. 2, trigger Q points output positive signal, Qn is negative, opt1 phototriodes conducting, driving SSR1 and SSR2 conductings, output
The DC voltage that a is V- under upper V+ is held, and opt2 phototriodes are cut off, and are not turned on, SSR3 and SSR4 are off shape
State.The H (1) in Hall sensor 8 detects the N pole fields output positive signal of iron core 3 simultaneously, becomes high electricity after amplifier
Redress and be fed to node C1 so that phototriode opt11 is turned on, driving SSR11 and SSR12 are turned on, the L (1) in coil 7
Electricity, induces the magnetic direction of S under N, the magnetic direction with iron core 3(Upper N, lower S)Attracting magnetic force is formed, with the increasing of electric current
Plus, the magnetic field force between coil L (1) and iron core 3 constantly increases, when suction F is more than the weight Mg of iron core 3 and iron core 3 and guideway 5
During the frictional force sum of wall, iron core 3 overcomes resistance to start upward accelerated motion;
When rising towards H (2), the N poles output positive signal of H2 sensing iron cores 3, positive signal becomes after amplifier
High level feeds back to node C2 so that phototriode opt21 is turned on, and SSR21 and SSR22 conductings, L (2) induce S under N
Magnetic direction, the magnetic direction with iron core 3(Upper N, lower S)Form attracting magnetic force, produced magnetic force cause iron core 3 continue by
It is upper to accelerate.Because the operation bound of iron core 3 is apart from length and the winding of coil 7 and Hall sensor 8 arrangement distance
Adjoining dimensions, while the N poles of iron core 3 are detected by H (2), H (1) just detects S poles, the negative signal that H (1) is detected
Become low level after amplifier and feed back to C1 points so that opt12 is turned on, driving SSR13 and SSR14 conductings, coil L (1)
It is reverse electric, it is coil-induced go out upper S under N magnetic direction, now L (1) and iron core 3 magnetic direction(Upper N, lower S)Formation repels each other
Magnetic force, have the thrust of upper act to iron core 3 so that iron core 3 simultaneously by it is upper suction and under push away two kinds of upward active forces;
When iron core 3 is continued up, during close to H (3), suction and coil L (2) of the same iron core by coil L (3)
Thrust, corresponding coil takes over conducting successively, the constantly motion upwards of iron core 3, and one of top is just left when winding is moved to
During coil, what now coil L (n) was induced is the magnetic direction of N under upper S, is that repulsion is upward to iron core 3 so that iron core 3 continues
Upwards;
When the compression spring 2 of iron core 3 is close to last Hall sensor H (n), H (n) senses positive signal, and passes through
The Qn ends that amplification feeds back to rest-set flip-flop are crossed, now opt1 is cut off, and SSR1 and SSR2 are turned off, and opt2 is turned on, and driving is solid
State relay SSR3 and SSR4 are turned on, and output end voltage reversely, that is, exports the DC voltage that a is V+ under upper V-, due to RS triggerings
Utensil has latch effect, so the voltage direction of this output end can be always maintained at constant, the Hall biography until being nearly in lower end
Just it is changed during sensor H (0).Because the electric current with uphill process is just on the contrary, coil L (n) induces the magnetic field side of N under upper S
To now, iron core 3 is by magnetic field force, magnetic core self gravitation, relative motion frictional force and the spring force for being placed in upper limit
Force iron core 3 to stop Deng simultaneously downward collective effect and start counter motion;
Iron core 3 is accelerated downwards, when close to L (n-1) coil, i.e., when close to H (n-1) Hall sensor, H (n-1) feels
The S poles negative signal of iron core 3 should be arrived, amplified to feed back to C (n-1) node, opt (n-1) 2 is turned on, driving SSR (n-1) 3 and SSR
(n-1) 4 conducting, L (n-1) it is coil-induced go out upper S under N magnetic direction, L (n-1) coil have the pulling force downward to iron core, iron
While core S is extremely close to H (n-1), the N of iron core 3 extremely senses positive signal close to H (n), H (n), and Cn is fed back to by amplification,
Optn1 turn on, driving SSRn1 and SSRn2 conducting, Ln it is coil-induced go out upper S under N magnetic direction, Ln coils have to iron core 3
Downward thrust, i.e., now iron core 3, simultaneously by the thrust and the pulling force of next coil of a upper coil, accelerates it downward
Motion;
Iron core 3 is constantly moved downward, and coil 7 is in continuous alternate conduction.When iron core 3 moves to bottom, have
Very high speed, forms very big impulsive force, drives the iron hammer 4 of front end to hit electrode bar, electrode bar is pressed people ground, work as iron
When core 3 moves to lower end, the H (0) in hall sensor 8 detects the S poles negative signal of iron core 3, and is fed back by amplifying circuit
To the input S of rest-set flip-flop, another stroke starts, gone round and begun again, iron core 3 at the track of guideway 5 above and below do at a high speed
Move back and forth, produce great impulsive force, electromagnetic wand is driven underground a step by a step, it is achieved thereby that the mechanization of drop bar
It is automatic to install, a large amount of labours are saved, drop bar installation exercise efficiency is improved.
