Description
Technical field
The utility model relates to gate control fields, and in particular to gate piston.
Background technique
Currently, the piston that gate folding generally uses all is large-scale hydraulic piston, piston rod and hydraulic cylinder own wt
Larger, due to the fully extended hydraulic cylinder of piston rod in closing gate, the end of piston rod is apart from hydraulic cylinder drive end bearing bracket nature row
Journey a distance, because piston rod own wt is heavier, dust-proof platen inner wall can be generated with piston rod top at hydraulic cylinder drive end bearing bracket
Shearing force is easy to be pulled so as to cause piston rod surface, and piston wear is serious, influences its service life.
Utility model content
For technical problem present in background technique, the utility model provides a kind of valve piston, can allow gate
Hydraulic cylinder when piston rod is retracted and is stretched out all in a horizontality, eliminate at hydraulic cylinder drive end bearing bracket dust-proof platen inner wall with
The shearing force that piston rod top generates reduces piston rod surface abrasion.
To achieve the goals above, the utility model provides following technical solution:
A kind of gate piston, including the dust-proof platen of hydraulic cylinder, end cap, support and piston rod, the hydraulic cylinder drive end bearing bracket pressure
Pan Chu is also equipped with load bearing support component, and the load bearing support component includes pedestal, bracket, upper backup pad, lower supporting plate and support
Wheel, the upper backup pad and lower supporting plate are connected to frame upper and bottom, and the upper backup pad is equipped with support roller, described
Support roller is connected at hydraulic cylinder drive end bearing bracket platen.The setting up of load bearing support component make hydraulic cylinder when piston rod is retracted and is stretched out all
Shearing force of the dust-proof platen inner wall to piston rod upper surface at horizontality, elimination hydraulic cylinder drive end bearing bracket.Gate is opening and closing
In the process, piston can horizontal traversal, drive support roller along rolling around on upper backup pad when piston is run, it can to realize
Supporting role, and do not influence piston motion.
Preferably, the bracket is equipped with screw rod, the screw rod passes through lower supporting plate and connects with lower supporting plate upper surface
Place is met equipped with nut, by nut come the height of adjusting bracket.
Preferably, the bracket is additionally provided with damper, the top and bottom of the damper respectively with upper backup pad and
Lower supporting plate is fixedly connected.It is shaken during piston motion, damper can reduce the shake that support roller occurs during scrolling
It is dynamic.
Preferably, the damper contains spring, package assembly, internal member, the internal member is placed on spring top, described
Package assembly is placed on spring lower part, and there are gaps between internal member and package assembly.
Preferably, be welded with post supports between the screw tip and upper backup pad, the post supports with
Support roller is axially parallel, for increasing the bearing area of bracket, reinforced support stability.
The utility model has the beneficial effects that being made hydraulic by installing load bearing support component at hydraulic cylinder drive end bearing bracket platen
Cylinder can be in horizontality when piston rod is retracted and is stretched out, and can eliminate at hydraulic cylinder drive end bearing bracket dust-proof platen inner wall to piston
The shearing force of bar upper surface reduces piston rod surface abrasion, extends piston service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of load bearing support component position in the utility model Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of gate piston, including the dust-proof platen 2 of hydraulic cylinder 1, end cap, support 4 and piston rod 3,
Load bearing support component is also equipped at the dust-proof platen 2 of hydraulic cylinder drive end bearing bracket, the load bearing support component includes pedestal 7, branch
Frame, upper backup pad 5, lower supporting plate 6 and support roller 8, the bracket include 1 screw rod 14 and 2 damper, 2 dampers along
Support roller 8 is axial to be mounted on side by side between upper backup pad 5 and lower supporting plate 6, and the damper contains spring 11, package assembly 10, interior
External member 9, the internal member 9 are placed on 11 top of spring, and the package assembly 10 is placed on 11 lower part of spring, internal member 9 and package assembly 10
Between there are gap, mounting dampers can not only reduce the vibration that support roller 8 occurs during scrolling but also may be implemented support make
With.The screw rod 14 passes through lower supporting plate 6, nut 15 is being housed with 6 upper surface junction of lower supporting plate.Nut 15 is mainly used for
The height of adjusting bracket keeps bracket more firm, 14 top of screw rod and upper support to increase the bearing area of screw rod 14
Post supports 13 are also welded between plate 5, the post supports 13 are axial parallel with support roller 8, and with screw rod 14 at " T " word
Shape.
The upper backup pad 5 is equipped with support roller 8 above, and the support roller 8 is connected at the dust-proof platen 2 of 1 drive end bearing bracket of hydraulic cylinder.Lock
For door in moving process, piston meeting horizontal traversal drives support roller 8 to roll around on upper backup pad 5, i.e., when piston is run
Supporting role may be implemented, and do not influence piston motion.
When the fully extended hydraulic cylinder 1 of piston rod 3 and when support roller 8 is in damper position, load bearing support component is adjusted
Whole height, so that hydraulic cylinder 1 is in horizontality, then by 15 adjusting screw rod of nut, 14 height, so that at upper backup pad 5
In horizontality, so that the support force that load bearing support component is acted in piston motion on hydraulic cylinder 1 is always consistent.
Load bearing support component plays the role of lifting, to make hydraulic cylinder 1 in piston by giving 1 one support forces of hydraulic cylinder
The retraction of bar 3 and when stretching out all in horizontality, eliminate at 1 drive end bearing bracket of hydraulic cylinder dust-proof 2 inner wall of platen to 3 upper surface of piston rod
Shearing force, greatly reduce piston rod 2 abrasion, prolong its service life.
