Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now compares accompanying drawing and describe in detail
The embodiment of the present invention.
As shown in Figure 1 and Figure 2, slab ejecting device of the present invention mainly include upper body 1, lower body 3, returning spring 13,
Roll wheel assembly 10, track 4, power set and Bei Cheng mechanisms.Power set in the present embodiment are Electrohydraulic push rod 7, the He of upper body 1
It is fixedly connected between lower body 3 by standard connector 2.
As shown in figure 3, roll wheel assembly 10 has two groups, every group includes four directive wheels 101, two rollers 103, two supports
102, wherein, directive wheel 101 and roller 103 are installed concentratedly on support 102, are then fixedly mounted on down by connecting bolt 104
On car body 3, the integrated morphology of wheel group to change and easy to maintenance quick, wherein, the position of roller 103 and directive wheel 101 can
To be completed by adjusting shims 105.Roll wheel assembly 10 can be steady in track 4 in the presence of Electrohydraulic push rod 7 and pressure head 6
Operation, security reliability are high.
As shown in Figure 4 and Figure 5, had additional on upper body 1 and cut somebody's hair 11, cutting somebody's hair 11 rolls certain curvature by steel plate and form.Push away
First 11 are fixedly mounted on upper body 1 by upper and lower two connecting pins 12, and the lower connecting pin bores on upper body 1 is processed into elongated hole,
For when cut somebody's hair 11 abrasion after regulation cut somebody's hair 11 movement travel.The 11 Curl structure of cutting somebody's hair can effectively buffer slab to pushing away
First 11 or even the impact of ejecting device.
Bei Cheng mechanisms are provided between track 4 and lower body 3, Bei Cheng mechanisms include cam body 8, block 14 and are arranged on
Inclined guide groove 9 on the inwall of track 4.Connected between mobile lower body 3 and static track 4 by high rigidity returning spring 13
Connect.The effect of returning spring 13 is after completing to push away steel action, and lower body 3 is resetted.Cam body 8 can by being connected with bearing pin 5
To be slided in guide groove 9, under the promotion of pressure head 6, the lower surface of cam body 8 and the protrusion block 14 of the left end of lower body 3
Inclined-plane is bonded all the time.The final mean annual increment movement of body movement should be that the stroke of Electrohydraulic push rod 7 and cam body 8 slide along guide groove 9
Displacement sum.
The operating principle that slab ejecting device is moved to Fig. 2 by Fig. 1 is as follows：
The termination of Electrohydraulic push rod 7 is connected with pressure head 6, and Electrohydraulic push rod 7 promotes cam body 8 to move right with dynamic head 6, due to
Inclined-plane of the concave profile of cam body 8 all the time with the protrusion block 14 of lower body 3 is bonded, then cam body 8 finally promotes lower body 3
Move to right.Meanwhile the bearing pin 5 being connected with the upper end of cam body 8 slides to the right in the guide groove 9 above static track 4,
Therefore, displacement S2 caused by lower body 3 is greater than the displacement S1 of Electrohydraulic push rod 7, i.e. completes to realize greatly under the driving of small stroke
The action of stroke, also it is exactly the principle place of Bei Cheng mechanisms as above.After the completion of steel action is pushed away, in the effect of returning spring 13
Under, lower body 3 resets, and returns to initial position, is ready for action next time.
Embodiments of the invention are described above in conjunction with accompanying drawing, but the invention is not limited in above-mentioned specific
Embodiment, above-mentioned embodiment is only schematical, rather than restricted, one of ordinary skill in the art
Under the enlightenment of the present invention, in the case of present inventive concept and scope of the claimed protection is not departed from, it can also make a lot
Form, these are belonged within the protection of the present invention.
