Specific embodiment
The present invention is further illustrated below in conjunction with the embodiment shown in that figure.
As shown in Figure 1, including two windages in left and right present invention firstly provides a kind of train wind resistance bidirectional braking device
Brake unit.The structure composition of each unit is identical, by the linkage of two units, realizes that two blocks of left and right wind wing plate 2 is anti-simultaneously
To opening and closing (when opening and closing at the same time, two blocks of wind wing plates 2 are relatively reverse interleaved).Specific embodiment is as follows:
Fixed substrate 15 is mounted on roof 1.There are two shaft seating, shaft seating 14 and shafts for installation in fixed substrate
Support 23；Two crank supports, crank support 12 and crank support 18；Two hydraulic cylinders bearings, hydraulic cylinders bearing 13 and hydraulic
Cylinder support 17.Shaft 25 is mounted in the bearing 24 in shaft seating 14 and shaft seating 23.2 lower surface of wind wing plate and left-hand rotation arm
3 and right-hand rotation arm 5 connect.Left-hand rotation arm 3 and right-hand rotation arm 5, which are connected by key, to be mounted in shaft 25.25 one end of shaft is equipped with gear
26.When a shaft is under the drive of wind wing plate 2, when as spindle rotation, by by the external toothing of gear, another is driven
Shaft is rotated toward opposite direction, and then opens another wind wing plate 2.
Crank is divided into two groups of left and right.Left crank includes inner crank 1 and outboard crank 1, and right crank includes inside
Crank 2 10 and outboard crank 28.Left crank one end is connect by pin shaft with crank support 18, the other end and passes through pin shaft and liquid
Push rod 1 and left connecting rod 22 is pressed to connect.Right crank one end is connect by pin shaft with crank support 12, the other end and passes through pin shaft
It is connect with hydraulic push rod 29 and right connecting rod 7.
Hydraulic cylinder is divided into two groups of left and right, hydraulic cylinder 1 and hydraulic cylinder 2 11.Hydraulic cylinder 1 passes through pin shaft and hydraulic cylinder
Support 17 is connected, and hydraulic cylinder 2 11 is connected by pin shaft with hydraulic cylinders bearing 13.Each hydraulic cylinder respectively has a hydraulic push rod dress
At its effect end.Hydraulic cylinder 1 is equipped with hydraulic push rod 1, and hydraulic cylinder 2 11 is equipped with hydraulic push rod 9.Hydraulic push rod passes through pin
Axis is connect with connecting rod.Connecting rod is divided into two groups of left and right, including left connecting rod 22 and right connecting rod 7.Hydraulic push rod 1 and 22 phase of left connecting rod
Even, hydraulic push rod 29 is connected with right connecting rod 7.Connecting rod support is divided into two groups of left and right, connecting rod support 4 and connecting rod support 26.Connecting rod
Support is mounted on the left and right sides of 2 lower surface of wind wing plate.22 other end of left connecting rod is connected by pin shaft with connecting rod support 4, right company
7 other end of bar is connected by pin shaft with connecting rod support 26.
After with above structure feature, in conjunction with shown in Fig. 2 and Fig. 3, the present invention can be implemented by following procedure:
Referring to figs. 1 and 2, when train normally travel, that is, when not needing braking, wing plate is in a horizontal position.At this time
Hydraulic cylinder is in contraction state, drives crank and connecting rod by hydraulic push rod, and then wind wing plate 2 is solid under the action of convergent force
It is scheduled on non-brake horizontal position.Such as Fig. 2, at this point, hydraulic push rod is in ejection state, so that crank and connecting rod bending and then shape
At stable convergent force.
In conjunction with shown in Fig. 1 and Fig. 3, when train is braked, windage of the opening direction towards current of traffic
Brake unit preferentially plays a role.As Fig. 3 drives crank and company by hydraulic push rod at this point, hydraulic cylinder is in tensional state
Wind wing plate 2 is released and is upturned by bar.Wind wing plate 2 is opened to rapidly vertical position under the wind-force effect that train operation generates
It sets.Specifically, if by taking the visual angle of Fig. 1 as an example: when train from figure from it is right advance toward left direction when, be in starting figure on the right side of
Brake unit while connecting rod jacks up three o'clock wind wing plate 2, is driven under the tensile force effect of right side hydraulic cylinder by gear 26
The shaft in another left side turns direction along opposite axis and rotates, and with this, opens simultaneously the wind wing plate 2 of left hand brake unit.In this way, making
When dynamic, the wind wing plate 2 of two brake units plays a role simultaneously, and under this state, the hydraulic cylinder of left hand brake unit is in laborsaving
State only has Auxiliary support effect to its connecting rod；Conversely, then starting in figure when train is by direction traveling from left to right in figure
The brake unit in left side, similarly, on right side, hydraulic cylinder generates drawing force, to jack up left side wind wing plate and drive right sided cell
Wind wing plate only have Auxiliary support effect to its connecting rod at this point, the hydraulic cylinder of right side brake unit is at laborsaving state.
After completing above-mentioned implementation process, following characteristics of the present invention should be able to be embodied:
This invention simplifies configuration settings and personnel to operate, and significantly improves wind effects.Either in the sky to vehicle
Between, structural strength, weight and design difficulty etc. will be much better than existing windage Brake Design.
This hair can be understood and applied the above description of the embodiments is intended to facilitate those skilled in the art
It is bright.Person skilled in the art obviously easily can make various modifications to these embodiments, and described herein
General Principle is applied in other embodiments without having to go through creative labor.Therefore, the present invention is not limited to the above embodiments,
Those skilled in the art's announcement according to the present invention, improvement and modification made without departing from the scope of the present invention all should be in this hairs
Within bright protection scope.
