Description
Technical field
Positioner is the utility model is related to, specifically a kind of Pneumatic casing elevator or chuck slips body positioner.
Background technology
Pneumatic casing elevator/chuck is the indispensable mechanized shaftmouth instrument of petroleum gas casing job, its work(
Can be clamping and lifting heavy caliber, the sleeve pipe of large-tonnage.Elevator/the chuck is when repairing, changing slips body or dental lamina, it is necessary to will
Slips body is in extreme higher position.It is actual repair, change slips body, dental lamina during, when slips body is opened and is in highest
During state, it sometimes appear that gas circuit disconnects suddenly（Die）Or oil circuit disconnects suddenly（Oil-break）, make effect of the slips body in deadweight
It is lower to fall suddenly；When slips body is in extreme lower position, malfunction that may be due to operating personnel or other accidentalia, by gas
The air operated reversing valve of cylinder is opened, and makes cylinder piston rod up, and driving equalizer bar moves upwards, is driven slips body up and is opened,
To repair, change slips body, the operating personnel of dental lamina cause serious injury.
Utility model content
To solve the above problems, the utility model provides a kind of Pneumatic casing elevator or chuck slips body positioner, energy
Effectively positioning slips body is in highest and extreme lower position, it is ensured that repairs, changes slips body, the personal of operating personnel of dental lamina is pacified
Entirely.
The technical solution adopted in the utility model is：Pneumatic casing elevator or chuck slips body positioner, including bias
Locating dowel, locking nut, locking wrench and the equalizer bar limited block for being fixed on equalizer bar one end, the locking wrench are determined with bias
Position post is connected to control eccentric locating dowel to rotate, and locking nut is used to fix eccentric locating dowel on locking wrench, described
Equalizer bar is connected so that slips body opens or closes by slips rack rod with slips body.
The equalizer bar drives it to move upwards by cylinder piston rod.
The beneficial effects of the utility model are：Using slips body positioner, when slips body is in extreme higher position by it
Positioning makes it to fall or must not be elevated when slips body is in extreme lower position, efficiently locates slips body in highest and most
Lower position, it is ensured that repair, change slips body, dental lamina operating personnel personal safety.

Embodiment
In order to deepen to understanding of the present utility model, make below in conjunction with embodiment and accompanying drawing to of the present utility model into one
Step is described in detail, and the embodiment is only used for explaining the utility model, does not form the restriction to the scope of protection of the utility model.
As shown in Figures 1 to 4, Pneumatic casing elevator or chuck slips body positioner, including eccentric locating dowel 1, locking
Nut 2, locking wrench 3 and the equalizer bar limited block 5 for being fixed on the one end of equalizer bar 4, locking wrench 3 are connected with eccentric locating dowel 1
For controlling eccentric locating dowel to rotate, locking nut 2 is used to fix eccentric locating dowel 1 on locking wrench 3, and equalizer bar 4 is logical
Slips rack rod 6 is crossed to be connected with slips body 7 so that slips body opens or closes.Therefore, it is just fixed as long as located equalizer bar
Position slips body.
Equalizer bar 4 drives it to move upwards by cylinder piston rod.
Operation principle：
1st, slips body is positioned in extreme higher position
For elevator/chuck in the case of normal work, the eccentric locating dowel of slips body positioner is in such as Fig. 3 or Fig. 4
Shown solid line position.
When slips body is thus lifted to extreme higher position, operation locking wrench is rotated by 90 ° in the direction of the clock, eccentric locating dowel
Horizontally rotate in dotted line position as shown in Figure 3 or Figure 4, eccentric locating dowel upper surface supported to below equalizer bar limited block,
Slowly decentralization equalizer bar makes eccentric locating dowel support equalizer bar limited block, then tightens locking nut, now, cylinder piston rod
Or cylinder plunger has arrived extreme position (can not move upwards again), propped up by eccentric locating dowel downwards so as to which slips body be positioned
In extreme higher position.
2nd, slips body is positioned in extreme lower position
For elevator/chuck in the case of normal work, the eccentric locating dowel of slips body positioner is in such as Fig. 3 or Fig. 4
Shown solid line position.
When slips body transfers to extreme lower position, operation locking wrench is rotated by 90 ° in the direction of the clock, eccentric locating dowel water
Flat turn is dynamic in dotted line position as shown in Figure 3 or Figure 4, eccentric locating dowel lower surface is pressed onto above equalizer bar limited block, then
Locking nut is tightened, slips body is now positioned at extreme lower position.
Slips body is in highest, extreme lower position, as long as eccentric locating dowel supports or pushed down the limited block of equalizer bar, balance
Beam cannot just move again, so as to reach the purpose of positioning slips body.
If cancelling positioning function, lock nut is first unclamped, then operates locking wrench and is rotated by 90 ° counterclockwise,
Eccentric locating dowel is departed from equalizer bar and be in solid line position as shown in Figure 2, then tighten lock nut.
