Background

In the oil drilling engineering, the mud pump is used as a core component of a drilling machine and plays a role in providing power for the circulation of drilling mud, ensuring that drill cuttings can be carried to the ground for treatment, protecting a drill bit and a well wall, and prolonging the service life of the drill bit and improving the mechanical drilling speed. The power of the slurry pump is realized by the reciprocating motion of a piston rod driving a piston in a cylinder sleeve. The piston therefore acts as a wearing part for the mud pump and needs to be replaced frequently. The existing mud pump structure is mostly in a mode that a dielectric rod is connected with a piston rod through a hoop, and when a piston moves to a back dead center position, the piston rod cannot be directly taken out from a cylinder sleeve. When the piston is replaced each time, the cylinder sleeve needs to be removed, then the hoop connected with the intermediate rod and the piston rod is disconnected, and the piston rod is removed. And after the piston is replaced, the piston is installed in the reverse order. The replacement process is complicated, and the labor capacity of workers is large, thereby wasting time and labor.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model provides a novel quick assembly disassembly slush pump piston rod which characterized in that: comprises an intermediate rod 1 and a piston rod 6; the intermediate rod 1 is connected with the piston rod 6 through a sleeve; the outer diameters of the intermediate rod 1 and the sleeve are consistent.

The sleeve consists of a first sleeve 2 and a second sleeve 4; the first sleeve 2 and the second sleeve 4 are both in a semi-circular structure, and a circular groove 7 is arranged in the semi-circular structure; a lug 8 is arranged in the ring groove 7; the projection 8 is located at the center of the ring groove 7.
