Seat；One base diameter 250mm leaves at high 130mm centers the hydraulic lift cylinder and a hand hydraulic pressure of diameter phi 49mm through hole
Pump group into.When using, first hydraulic pressure base is placed on draining cylinder mouth, then from slush pump cooling cylinder draining cylinder mouth, by long spiral shell
Rotation leading screw is put in slush pump cooling cylinder, then hydraulic lift cylinder sleeve is mounted in hydraulic lift by the through hole of central diameter 49mm
On screw, being lifted screw by a people makes ratchet catch valve seat bottom, in addition a people by three-jaw spiral pressure cap from silk
Thick stick upper end is threaded to hydraulic lift cylinder top, and pressure cap is firmly pounded into tight with hammer, subsequently connects hydraulic pressure handlance and hydraulic lift cylinder
Pick up and, start handlance, to hydraulic lift cylinder hydraulic oil is injected so as to which outer cylinder is raised, and valve seat is extracted.Current is all
That seat extractor, it is more heavy, need at least two people to operate with the use of can just complete this during operation, personnel's mismate appearance
Easily crowded handss, there is also uncertain potential safety hazard in use.
Utility model content
For the problems of the prior art, this utility model takes out there is provided a kind of cylinder plunger formula mud pump seat
Device.
Technical problem to be solved in the utility model is achieved through the following technical solutions：
A kind of cylinder plunger formula mud pump seat extractor, it is characterised in that described mud pump seat extractor
It is made up of pawl device, hydraulic piston cylinder, support base and portable hydraulic power source；Wherein described pawl device is carried by ratchet
Connecting rod, ratchet bearing and ratchet composition is risen, ratchet lifts the bottom of connecting rod and is fixed on ratchet bearing, and ratchet bearing bottom is fixed
Ratchet；The top that the lift piston rod that the bottom of the piston in the hydraulic piston cylinder is fixed lifts connecting rod with ratchet is connected；Institute
State support base and be provided with groove, the hydraulic piston cylinder is placed in the groove of support base；The power of the hydraulic piston cylinder connects
The entering of port and portable hydraulic power source is met, hydraulic fluid pipeline is returned and is connected.
Further, the support base is placed on the cylinder mouth of slush pump cooling cylinder.
