Abstract
The utility model discloses a tool used for mounting a piston of a slurry pump. The tool comprises a circular ring, a movable lead screw, a jacking head, a movable lead screw nut, fixed lead screw nuts, fixed lead screw handles and fixed lead screws. The circular ring and the jacking head are installed at two ends of the movable lead screw respectively; the movable lead screw nut is installed on the movable lead screw; two fixed lead screw nuts are symmetrically welded on both sides of the movable lead screw nut; the axial lines of the two fixed lead screw nuts are positioned in a line and are perpendicular to the axial line of the movable lead screw nut; the two fixed lead screws are provided and are installed in the two fixed lead screw nuts respectively; the fixed lead screw handles are formed at the ends of the two fixed lead screws respectively; and the movable lead screw nut and the two fixed lead screw nuts form a nut string together. The tool has the benefits that the damage degree of a piston spare nut and the pull rod screw threads can be effectively reduced; the one-man operation can be achieved; the incidence of accidents such as hand hit, hand squeezing and the like can be avoided; the higher safety can be achieved; and the work efficiency can be improved.
Description
Technical field
The utility model relates to a kind of jacking mechanism that piston is installed, especially a kind of specific purpose tool that the mud pump for petroleum drilling piston is installed.
Background technology
At present, in Process of Oil Well Drilling, mud piston is installed by drilling crew, be an arduousness and the work of wasting time and energy, need earlier piston assembly to be packed into cylinder sleeve, a people holds afterburning thick stick then, makes afterburning thick stick lower end aligned piston be equipped with cap, an other human iron hammer knocks afterburning thick stick upper end, makes piston in place.This method makes piston be equipped with cap easily and pull bar is impaired scraps.And, need 2 people's coordinating operations just can finish assembling, therefore, yield poor results.Simultaneously, knocking and coil pump hangs fashionable existence and pounds hand, squeezes unsafe factor such as hand.
The utility model content
The purpose of this utility model provides a kind of instrument that mud piston is installed, and the utility model is achieved in that it comprises annulus, movable leading screw, jacking head, movable feed screw nut, fixedly feed screw nut, fixedly leading screw handle, fixedly leading screw.Be separately installed with annulus and jacking head at the two ends of movable leading screw, movable feed screw nut is installed on the movable leading screw, is welded with two fixedly feed screw nuts at this activity feed screw nut monosymmetric; Two fixedly feed screw nut axis point-blank, and with the axis normal of movable feed screw nut; Fixedly leading screw has two and be installed in two respectively fixedly in the feed screw nut, two fixedly the end of leading screw be processed with fixedly leading screw handle respectively; Movable feed screw nut and two fixedly feed screw nut form the nut string jointly.The beneficial effects of the utility model are, it has reduced the extent of damage that piston is equipped with cap and pull bar screw thread effectively, but one man operation, the generation of avoided pounding hand, squeezing accidents such as hand, have higher security, improved operating efficiency, and have that manufacture craft is simple, cost is low, easy for installation, the advantage that is suitable for maintenance.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.Among the figure 1, annulus, 2, movable leading screw, 3, the jacking head, 4, movable feed screw nut, 5, fixing feed screw nut, 6, fixing feed screw nut, 7, fixing leading screw handle, 8, fixing leading screw, 9, fixing leading screw handle, 10, fixing leading screw.
The specific embodiment
With reference to accompanying drawing 1, a kind of instrument that mud piston is installed of the utility model, it comprises annulus 1, movable leading screw 2, jacking 3, movable feed screw nut 4, fixedly feed screw nut 5, and fixedly feed screw nut 6, fixedly the leading screw handle 7, and fixedly leading screw 8, and fixedly the leading screw handle 9, and fixedly leading screw 10.Be separately installed with annulus 1 and jacking 3 at the two ends of movable leading screw 2, movable feed screw nut 4 is installed on the movable leading screw 2, at the monosymmetric fixedly feed screw nut 5 and fixedly feed screw nut 6 of being welded with of this activity feed screw nut 4; Fixedly feed screw nut 5, fixedly feed screw nut 6 axis point-blank, and with the axis normal of movable feed screw nut 4; Fixedly leading screw 8, fixedly leading screw 10 is installed in fixedly feed screw nut 5 respectively and fixedly in the feed screw nut 6, at fixing leading screw 8, fixedly leading screw 10 two ends are processed with fixedly leading screw handle 7 and fixedly leading screw handle 9 respectively; Movable feed screw nut 4, fixedly feed screw nut 5, fixedly feed screw nut 6 is hex nut.Movable feed screw nut 4, fixedly feed screw nut 5, fixing feed screw nut 6 composition nut strings jointly.Operation principle of the present utility model is, piston assembly is packed into behind the cylinder sleeve, movable leading screw jacking 3 is withstood on piston to be equipped with on the cap, fixedly leading screw 8, fixedly leading screw 10 is inserted by the cylinder cap side opening, and tighten respectively at fixing feed screw nut 5, fixedly in the feed screw nut 6, afterburning thick stick is injected by annulus 1, by rotate afterburning thick stick movable leading screw 2 is clockwise rotated can the jacking piston, make piston in place.
