Specific implementation mode
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail.
Embodiment：Referring to Fig. 1, Fig. 2, Fig. 3, a kind of lift car shock-absorbing limiting device, including installation positioning plate 1, it is described
Installation positioning plate 1 is respectively provided with a mounting hole at its both ends.The side of the installation positioning plate 1 has one vertically to determine with installation
The limiting plate I 2 of position plate 1, the limiting plate I 2 extend to the middle part of installation positioning plate 1 from one end of installation positioning plate 1；It is specific real
Applying makes, and the limiting plate I 2 is bent and extended to form by the lateral edges of installation positioning plate 1, to make integral strength higher.The limit
Position plate I 2 close to installation positioning plate 1 middle part one end to being bent away from the direction of installation positioning plate 1 and extend to form limiting plate II
3, keep limiting plate I 2 and limiting plate II 3 whole L-shaped.
Damping nail 4 is respectively equipped on limiting plate I 2 and limiting plate II 3；The damping nail 4 includes screw rod 41, bottom plate 42
And yielding rubber 43.The bottom plate 42 is set in one end of screw rod 41, and is fixedly connected with screw rod 41, the yielding rubber 43
It is molded as one with bottom plate 42 and 41 end of screw rod by way of cast；Wherein, the yielding rubber 43 is hemispherical, and will
41 end of screw rod coats；And the hardness of the yielding rubber 43 is shore 65 ± 5；To keep damping effect more preferable, limit effect
Fruit is more preferable, reliability higher.It is respectively welded in the adjacent side of limiting plate I 2 and limiting plate II 3 and is fixed with an attaching nut 5,
On limiting plate I 2 and limiting plate II 3, it is correspondingly connected with nut 5 and is equipped with via；The screw rod 41 of the damping nail 4 is far from yielding rubber 43
One end sequentially pass through attaching nut 5 and via, and be connected with 5 screw-thread fit of attaching nut, and the screw rod 41 passes through connection spiral shell
It is locked by locking nut 6 after mother 5 and via.
As shown in attached drawing 4, Fig. 5, when installation, a shock-absorbing limiting device is respectively set in the both sides of sedan-chair frame straight beam 7, and pass through
Two shock-absorbing limiting devices are fixed on car top 8 by bolt, to facilitate Field adjustment.It, can when 7 width of sedan-chair frame straight beam changes
The installation site for adjusting two shock-absorbing limiting devices provides the scope of application to ensure accurate positioning.Simultaneously with sedan-chair frame straight beam 7 with
For two shock-absorbing limiting devices by four point contacts, independent contact point can be voluntarily sized, and piece surface dimensional discrepancy is avoided to cause
Influence, provide positioning accuracy.
After a period of time is used for a long time, the yielding rubber 43 on damping nail 4 compresses, when caused location dimension deviation,
The position that damping follows closely 4 can be directly adjusted, without adjusting a whole set of shock-absorbing limiting device, adjustment is simply, conveniently.When usage time compared with
Long, 43 damping effect of yielding rubber on damping nail 4 is deteriorated, and when being unable to reach expected damping effect, replaceable damping nail 4 is kept away
Exempt from, with changing a whole set of shock-absorbing limiting device, effectively to avoid waste of material, reduce with changing this into.
