Effect promotes buffering effect.
3. beneficial effect
Buffer in the utility model is broken through the crane girder bottom soft limit Shi Huiyu in crane and is contacted, and plays
Hardness prevents the effect of crane lowering action；Once the connection between roof supporting and support fashioned iron, which is got loose, to be caused to buffer
Device loses effect, and roof supporting lower surface can first contact cushioning fender, so that two block buffering baffles are backwards to rotation, the activity of torsional spring
While rotating with it, under the reset response of torsional spring, so that the speed of roof supporting decline gradually decreases, buffer function is played；So
Rear support top plate following table face contact buffer spring, buffer spring are compressed, are gradually increased to the upward elastic force of roof supporting,
So that the speed of roof supporting decline further decreases, buffer function is further functioned as, until roof supporting stops decline；Limit
Baffle on support baseboard, can be improved the stability of postive stop baffle, can ensure limit function by they sup-port.Then this reality
Preferable with New Buffering limit function, stability is high.

Embodiment
A kind of vertical lift buffer unit as shown in Figure 1, including it is support baseboard 1, support fashioned iron 2, roof supporting 3, solid
Determine part 4 and buffer 5, support baseboard 1 is welded on support 2 bottom end of fashioned iron, and roof supporting 3 is welded on support 2 upper end of fashioned iron, buffering
Device 5 is fixed on roof supporting 3 by fixing piece 4；It is arranged on the support fashioned iron 2 positioned at roof supporting 3 and support baseboard 1
Between postive stop baffle 6,6 bottom surface of postive stop baffle is equidistantly equipped with the branch that is connected on support baseboard 1 around support fashioned iron 2
Strut 7, as shown in Figures 1 and 2,6 upper surface of postive stop baffle are located at support 2 two opposite sides of fashioned iron and are equipped with cushioning fender 8
With buffer spring 9, the cushioning fender 8 is pivotally attached to 6 upper surface of postive stop baffle, and junction is equipped with shaft 10, and described turn
Torsional spring 11 is set on axis 10, the active edges of the torsional spring 11 are located inside cushioning fender 8, the rotation rail of the cushioning fender 8
Mark is the segmental arc positioned at two 10 two-phase back sides of shaft, and the buffer spring 9 is at least four, they are located at two block bufferings
Two end sides of baffle 8；When torsional spring 11 in the raw when, 8 free end of cushioning fender is located at 3 corresponding side of roof supporting
The underface of edge.
In the present embodiment, as shown in Figure 1, the fixing piece 4 includes bolt 41 and nut 42.It easy can realize so slow
Fixed installation of the device 5 relative to roof supporting 3 is rushed, it is easy to implement.
In the present embodiment, the postive stop baffle 6 is welded on support fashioned iron 2.The fixing-stable of postive stop baffle 6 can be enhanced
Property, so as to ensure limit effect.
In the present embodiment, as shown in Figures 1 and 2, the free end of the cushioning fender 8 is fixed with bar 12.Bar 12
The arcwall face on surface makes that preferably support can be provided in 8 rotation process of cushioning fender for postive stop baffle 6.
In the present embodiment, as shown in Figures 1 and 2, on the postive stop baffle 6 of the opposite two sides of two pieces of cushioning fenders 8
Equipped with arc groove 13 compatible with bar 12.Because after bar 12 rotates, part is likely located at table on postive stop baffle 6

Space.
In the present embodiment, as shown in Fig. 2, 10 liang of end sides of the shaft are equipped with torsional spring 11.Setting can enhance torsion in this way
Spring 11 promotes buffering effect to the reset response of cushioning fender 8.
The concrete application process of above-mentioned vertical lift buffer unit are as follows:
When vertical lifting equipment decline, under inertia force and gravity, crane breaks through soft limit, crane
The position of former setting is crossed, crane girder bottom is contacted with buffer 5, plays the work that hardness prevents crane lowering action
With.If the roof supporting 3 and the junction of support fashioned iron 2 that are used to install buffer 5 are got loose, buffer 5 will not be acted as
With.
For above situation, when roof supporting 3 loosens, crane, buffer 5 decline with roof supporting 3, support
3 lower surface of top plate first contacts cushioning fender 8, so that two block buffering baffles 8 are backwards to rotating, the active edges of torsional spring 11 are rotated with it,
Under the effect of torsional spring 11, so that the speed that roof supporting 3 declines gradually decreases, buffer function is played；Then 3 following table of roof supporting
Face contact buffer spring 9, buffer spring 9 compress, and are gradually increased to the upward elastic force of roof supporting 3, so that branch support
The speed that plate 3 declines further decreases, and further functions as buffer function, until roof supporting 3 stops decline；Postive stop baffle 6 is logical
It crosses support rod 7 to be supported on support baseboard 1, the stability of postive stop baffle 6 can be improved, can ensure limit function.
As shown in the above, the buffer limit function of the utility model is preferable, and stability is high.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above
Variation, the modification of embodiment will all be fallen in the scope of the claims of the utility model.
