Abstract
The utility model provides a dissembling device for a piston of a sludge pump. The disassembling device comprises a bayonet, a chuck and a push-pull device and is characterized in that the push-pull device comprises a push-pull rod and a cylindrical push-pull base, wherein the push-pull rod is designed at the center of the top of the cylindrical push-pull base and is welded to or in threaded connection with the cylindrical push-pull base, the diameter of the upper part of the cylindrical push-pull base is larger than the diameter of the lower part of the cylindrical push-pull base, two symmetrical right-angle clamping grooves are arranged at two sides of the upper part of the cylindrical push-pull base, a round groove is arranged at the bottom of the cylindrical push-pull base, the chuck consisting of two bar-shaped clamping handles is clamped in the clamping grooves, one of the two clamping handles is connected with the round bayonet through a hinge pin, a cylindrical spring seat is arranged vertically at the lower part of the other clamping handle and is interlay provided with a spiral spring, and the spiral spring abuts against the round bayonet. The dissembling device is simple in structure, is convenient to use, is quick, time-saving and labor-saving when used for disassembling the piston of the sludge pump; and moreover, the piston is not damaged when the dissembling device is used for disassembling the piston of the sludge pump and therefore the service life of the piston is prolonged.
Description
Technical field
Used mud piston replacer when the utility model relates to oil drilling slush pump maintenance dismounting piston.
Background technology
During existing oil drilling slush pump repair demolition piston; Mostly be after the piston rod junction is taken apart; The moving slush pump bent axle of dish makes between pitch brace and the intermediary's pull bar and produces the gap, in the gap, put into iron rod again piston is released from cylinder sleeve, or between is encased inside article dish pump piston is ejected; Be time-consuming effort again, also dangerous.When piston is installed, plunger backer emitted put steel pipe and hit with a hammer again and squeeze in the cylinder sleeve, with sledgehammer piston is squeezed into mode in the cylinder sleeve and promptly require great effort and also damage parts easily.
Summary of the invention
The purpose of the utility model provides a kind ofly to be used in slush pump maintenance dismounting pistons work, i.e. the convenient power-saving mud piston replacer of safety again.In slush pump maintenance dismounting pistons work, use the mud piston replacer, can save maintenance time and reduce labor intensity, can improve repair quality again.
The technical scheme of the utility model realizes in the following manner:
The utility model comprises bayonet socket, dop and load push-pull, it is characterized in that load push-pull comprises pull bar and cylindrical push-and-pull seat, and pull bar design top central part on cylindrical push-and-pull seat is with welding between the cylindrical push-and-pull seat or be threaded; Cylindrical push-and-pull seat upper diameter is greater than lower diameter; Be provided with the square draw-in groove of two symmetries in the both sides, top, the bottom is provided with circular groove, and card is by the dop of being made up of two strip card handles in the draw-in groove; Wherein a card handle is connected with circular bayonet socket bearing pin; Be provided with the drum type brake spring base in another card handle bottom on vertically, be provided with helical spring in the drum type brake spring base, helical spring withstands on the annular bayonet socket.
Be provided with the inside corner that is complementary with the outer corner angle of piston tip hold-down nut in the annular bayonet socket week, on ring surface, be provided with a projection, transversely be provided with pin shaft hole at projection.
Compared with present technology the utility model has the following advantages:
1, the utility model is simple in structure, easy to use, the dismounting mud piston is fast time saving and energy saving.
2, when the dismounting mud piston, do not injure piston, prolonged the service life of piston.

The specific embodiment
For further disclosing the technical scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
The utility model comprises bayonet socket 4, dop 5 and load push-pull 7, it is characterized in that load push-pull 7 comprises pull bar and cylindrical push-and-pull seat, and pull bar design top central part on cylindrical push-and-pull seat is with welding between the cylindrical push-and-pull seat or be threaded; Cylindrical push-and-pull seat upper diameter is greater than lower diameter; Be provided with the square draw-in groove of two symmetries in the both sides, top, the bottom is provided with circular groove, and card is by the dop of being made up of two strip card handles 5 in the draw-in groove; Wherein a card handle is connected with annular bayonet socket 4 bearing pins; Be provided with the drum type brake spring base in another card handle bottom on vertically, be provided with helical spring 6 in the drum type brake spring base, helical spring withstands on the annular bayonet socket.
When using the utility model; If dismounting mud piston 2, two of dop 5 card handle tops are stuck in the square draw-in groove of both sides, cylindrical load push-pull seat top of load push-pull 7, wherein a card handle is connected with bayonet socket 4 with bearing pin; Drum type brake spring base in another card handle bottom is being loaded onto helical spring 6; The endoporus of the mud piston replacer that assembles along mud slurry pump cylinder jacket 1 advanced, the endoporus of bayonet socket 4 is stuck on the piston tip hold-down nut 3, produce an oblique card power; The pulling force of this oblique card power of leaning on and load push-pull just can easily be unloaded mud piston down.If the dress mud piston is laid down bayonet socket, piston is placed on the mouth of mud slurry pump cylinder jacket 1, withstand piston with dop, push hard load push-pull 7 and just can load onto piston, convenient and swift, time saving and energy saving.
