Bar will not rotate along the rotation direction of the first actuator, so as to preferably drive cock body to be ground.
It is further arranged to：The keeper of limitation fixed plate landing is provided with the slide bar positioned at the lower section of fixed plate.
By using above-mentioned technical proposal, when the second actuator breaks down, the fixed plate of landing is positioned part and supported
Touch, continue to slide so as to limit fixed plate, reduce existing potential safety hazard.
It is further arranged to：The keeper includes the first cutting ferrule portion, the second cutting ferrule portion and for locking the first cutting ferrule
The bolt and nut of slide bar is fixed in portion with the second cutting ferrule portion.
By using above-mentioned technical proposal, bolt is through the first cutting ferrule portion, the second cutting ferrule portion and screw thread connects nut
Connect, so as to which the first cutting ferrule portion and the second cutting ferrule portion are pressed abd fixed on slide bar；And can be to keeper in cunning by this kind of mode
Particular location on bar is adjusted, and ensure that the normal slip of fixed plate.
It is further arranged to：The base is provided with the Mobile base that slip enters immediately below cock body, the Mobile base
Some positioning holes for being used to position valve body of different sizes are provided with, the base is provided with driving Mobile base and realized toward polyslip
3rd actuator.
By using above-mentioned technical proposal, by the lower section of Mobile base removal fixed plate so that staff can transport lifting
Defeated next valve body is directly placed on Mobile base, is used to realize fixation of the valve body on Mobile base by positioning hole；Passing through
Three actuators drive Mobile base to realize and slid on base, and valve body is transported and is processed immediately below cock body.
It is further arranged to：3rd actuator is arranged in the lower section of base.
By using above-mentioned technical proposal, the 3rd actuator is played a protective role by this kind of set-up mode, and makes
The presence of three actuators will not cause to hinder to the work flow of valve body.
In summary, the invention has the advantages that：The setting of elastic component, which is reduced between cock body and valve body, to be occurred
Kill phenomenon and potential safety hazard existing for equipment reduced by the setting of keeper, Mobile base is set on base, it is convenient
The transport of valve body.
