Abstract
A kind of pantograph spring case of adjustable rigidity, including first bevel gear, first base, spring, two-way pneumatic motor, second bevel gear and second base, the first bevel gear is arranged in first base by revolute pair, first bevel gear internal diameter wall is provided with internal thread, spring is arranged in the internal thread of first bevel gear and forms screw pair, two-way pneumatic motor is fixed in first base, second bevel gear is fixed on the output shaft of two-way pneumatic motor and engaged with first bevel gear, lower spring end is fixed in second base, and spring upper end is kept freely.The first base is the upper cruciform bracing of pantograph, and second base is the carbon slipper bracket of pantograph.The present invention is simple in construction, can be during the traveling of electric locomotive, according to pantograph collector head rigidity optimal under the speed per hour, the regulation of real-time continuous is carried out to spring case rigidity, and the precision of regulation is high, when not changing spring case rigidity, air motor does not need pressurize, and reliability is improved while saving the energy.
Description
Technical field
It is specifically a kind of to adjust the pantograph spring case of rigidity the present invention relates to mechanical field.
Background technology
Pantograph is the electrical equipment that electrically-driven car obtains electric energy from contact net, installed in locomotive or motor-car roof
On.Pantograph spring case is an important composition part of pantograph, makes train in the state of high-speed cruising, the bow of pantograph
The height that grease head highness can follow contact net changes, it is ensured that the good contact of bow net, makes train is stable to be flowed.In train not
With under the speed of service, the Optimal Stiffness of spring case be it is different, the rigidity of bow it is excessive or it is too small can all influence bow net by
Properties of flow.Once bow net contact is bad, the traction power supply performance of train will be directly affected；More seriously, if pantograph
Structure is destroyed in operation, can not only be interrupted and be flowed, also usually cause the destruction of contact net system.Current electric locomotive is generally adopted
With the pantograph spring case for determining rigidity, rigidity is typically secured to above and below 10000N/m, it is impossible to carried out according to the operation speed per hour of train
Regulation.With the speed-raising of high ferro, the operation speed per hour of train needs to undergo the change from 0,000 ms/h to 350,000 ms/h, its
Corresponding optimal bow rigidity is also in an interior change in a big way.Proposed to have constituted change just using air spring by the scholar of Japan
Degree mechanism changes the function of pantograph rigidity to realize, but the device volume is bigger than normal, during use air path part need pressurize,
And there is the shortcomings of degree of regulation is relatively low.
The content of the invention
The pantograph spring case of rigidity can be adjusted in view of the deficiencies of the prior art, the present invention provides a kind of, passes through control
The rotating of two-way pneumatic motor, changes the effective interaction length of spring, block of bow collector of electric locomotive bow rigidity is entered with realizing
Row real-time continuous is adjusted.
To achieve these goals, present invention employs following technical scheme：
A kind of pantograph spring case of adjustable rigidity, including first bevel gear, first base, spring, two-way pneumatic motor,
Second bevel gear and second base,
The first bevel gear is arranged in first base by revolute pair, and first bevel gear internal diameter wall is provided with interior spiral shell
Line, spring is arranged in the internal thread of first bevel gear and forms screw pair, and two-way pneumatic motor is fixed in first base, and second
Bevel gear is fixed on the output shaft of two-way pneumatic motor and engaged with first bevel gear, and lower spring end is fixed on second base
On, spring upper end is kept freely.
The first base is the upper cruciform bracing of pantograph, and second base is the carbon slipper bracket of pantograph.
The Rectangular Section Spring that the spring is.
Compared with prior art, the beneficial effect that the present invention possesses：
The present invention is simple in construction, can be bent during the traveling of electric locomotive according to pantograph optimal under the speed per hour
Head rigidity, the regulation of real-time continuous is carried out to spring case rigidity, and the precision of regulation is high, when not changing spring case rigidity, gas
Dynamic motor does not need pressurize, and reliability is improved while saving the energy.Volume, quality of the present invention etc. and common spring box base
This is identical, after most pantograph repacking at present, other specification will not be caused to vary widely.
Brief description of the drawings
Fig. 1 is the structural representation of the pantograph spring case of adjustable rigidity of the present invention.
Embodiment
Technical scheme is further elaborated below by embodiment.
Embodiment 1
A kind of pantograph spring case of adjustable rigidity, including first bevel gear 6, first base 1, spring 4, two-way pneumatic horse
Up to 2, second bevel gear 6 and second base 5,
The first bevel gear 6 is arranged in first base 1 by revolute pair.First bottom plate is provided with through hole, the second cone
Gear 6 is installed in through-holes, the external diameter of second bevel gear 6 and the minor diameter fit of through hole.Two-way pneumatic motor 2 is fixed on the first bottom
On seat 1, second bevel gear 6 is fixed on the output shaft of two-way pneumatic motor 2 and engaged with first bevel gear 6.Therefore, start double
Rotated to air motor 2, pass through the engagement of second bevel gear 6 and first bevel gear 6 so that first bevel gear 6 is revolved in through-holes
Turn.Again because the internal diameter wall of first bevel gear 6 is provided with internal thread, spring 4 is arranged in the internal thread of first bevel gear 6 and formed
Screw pair, therefore, when first bevel gear 6 rotates, spring 4 is transported axially downward or upwards in the internal diameter of first bevel gear 6
It is dynamic, the lifting of second base 5 of the lower end of spring 4 will be fixed on and put down.
The first base 1 is the upper cruciform bracing of pantograph, and second base 5 is the carbon slipper bracket of pantograph.
The Rectangular Section Spring that the spring 3 is.
Extension elongation of the invention by changing spring, that is, change the practical function length of spring, reach regulation spring case
The purpose of rigidity.In course of normal operation, spring is only in part below first bevel gear in work, remainder with
First bevel gear keeps rigid contact.The screw pair of first bevel gear internal diameter is in self-locking state, whole system and common spring
Mechanical property it is identical, only two-way pneumatic motor ventilation in the state of, first bevel gear can just be rotated, and make spring case
Rigidity change.Because pantograph and car body need to keep electrical isolation, therefore control is implemented to it using two-way pneumatic motor
System.
