Group tightens together, and air spring 43 is peripherally equipped with asbestos sheet, and asbestos sheet is fixed on by bolt group on vibration charging vehicle
On body, anti-scald protection is carried out to air spring system 4.
The vibration charging vehicle services for electric melting furnace 9, and electric melting furnace 9 is arranged below platform front end, vibration charging vehicle
After reaching discharge zone, the discharge port of groove body 7 is corresponding up and down with 9 fire door of electric melting furnace, ensures that melting material 8 is fallen into electric melting furnace 9.
It connects with the mains, connects master operation screen.
More than, the vibration charging vehicle for impact of not resonating just is completed.
Do not resonate impact vibration charging vehicle implementation method it is as follows:
After melting material 8 is filled groove body 7, under the action of 2 synchronous walking motors 2, two adhesion wheels 11 and two
Driven wheel 12 carries vibration charging vehicle and integrally advances along track, reaches stop motion after discharge position.
When electric melting furnace 9 needs that melting material 8 is added, 2 synchronous vibration motors 6 are started to work, and so that vibrating body 5 is vibrated, are shaken
Kinetoplast 5 drives groove body 7 to vibrate together, and by the vibration effect of groove body 7, melting material 8 is moved along, and is fallen into electric melting furnace 9, melting
8 melting of melting material is iron liquid or molten steel by electric furnace 9.
When electric melting furnace 9 needs to stop that melting material 8 is added, 2 synchronous vibration motors 6 are stopped, then, vibrating body 5
Stop vibrating with groove body 7, melting material 8 is no longer moved along, no longer falls into electric melting furnace 9.
When the addition of melting material 8 in groove body 7 finishes, 2 synchronous vibration motors 6 are stopped, then, vibrating body 5 and slot
Body 7 stops vibration, and under the action of 2 synchronous walking motors 2, two adhesion wheels 11 and two driven wheels 12 carry and shake
Dynamic charging vehicle is integrally retreated along track to loading area, is fed, and after 8 charging of refining material, vibration charging vehicle is integrally etc.
Wait Order enters next cycle.
When 2 start-up operations of synchronous vibration motors 6, vibrating body 5 is made to vibrate, when vibrating body 5 drives groove body 7 to vibrate together,
In order not to allow the vibration force of vibration charging vehicle upper body to pass to vibration charging vehicle lower body, and then charging vehicle platform is passed to, shaken
The dynamic spring system that is provided between charging vehicle upper body and vibration charging vehicle lower body carries out vibration damping, has cut off the transmission of vibration force, and
In order to solve steel wire compressed spring resonance shock problem, spring system uses air spring system 4.
When air spring system 4 works, the inner cavity of air spring is filled with compressed air, forms a compressed air air column,
With the increase of oscillating load amount, the height of air spring reduces, and cavity volume reduces, and rigidity increases, the inner cavity of air spring
The effective bearing area of air column increases, and the bearing capacity of air spring increases at this time.
When oscillating load amount reduces, the height of air spring increases, and the cavity volume of air spring increases, and rigidity subtracts
Small, the effective bearing area of inner cavity air column reduces, and the bearing capacity of air spring reduces at this time.
So height of the air spring in effective travel, cavity volume, bearing capacity with oscillating load be incremented by with
Reduce and smoothly flexible transmission, the efficient control of amplitude and shock loads have occurred, the method for increasing, subtracting aeration quantity can also be used,
Adjust the size of the rigidity and bearing capacity of spring.
Air spring is not had due to its special material and unique structure, thus with metal spring and rubber spring
The characteristics of:
1, air spring has excellent non-linear hard characteristic, can effectively limit amplitude, avoid resonating, prevent from impacting,
The Nonlinear Characteristic Curve of air spring can carry out ideal design according to actual needs, and appearing as has near rated load
Lower rigidity value;
2, it since medium used by air spring is mainly air, thus is easy to implement active control;
3, the rigidity of air spring becomes with load, so under different loads, vibrating isolation system intrinsic frequency is hardly
Become, vibration isolating effect is also almost unchanged.
Design concept:
1. air spring selection principle:According to the model of oscillating batch charger(Load-bearing)Difference selects different bent capsule numbers
(1-3)Air spring and different number air spring individual.
2. be designed with auxiliary tank, realize automatic control adjusting, vibration charging vehicle do not have in tow loading line, prevent iron is funny from flying
It splashes the asbestos sheet of scald air spring, have air pressure alarm function.
According to the vibration charging vehicle for not having resonance to impact made of this design principle, effectiveness in vibration suppression is best, social benefit
It is maximum.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field
The common knowledge of those of ordinary skill.The scope of protection of the utility model is based on the contents of the claims, any to be based on this reality
The equivalent transformation carried out with novel technical inspiration is also within the protection scope of the utility model.
