Description
Technical field
The utility model relates to a kind of card assembly that plays and drags for lance structure, belongs to drilling equipment technical field used for geological prospecting.
Background technology
Lao Mao mechanism is on the top of inner tube assembly, and when fishing for inner tube assembly with fisher, dragging for spearhead will at the axis direction of whole drill string, and fisher just can block and drag for spearhead; After inner tube assembly proposes aperture, for ease of taking out the rock core in interior pipe, inner tube assembly will be positioned on ground, drags for spearhead and drags for lance seat and want half-twist.
The structure of used Lao Mao mechanism be mostly locating piece upper end have spring mounting hole, lower end with drag for lance seated connection and touch, by the potential energy of spring-compressed, will spearhead be dragged for be stabilized in the position of needs.Locating piece is generally sphere-contact with the contact surface dragging for lance seat or leg-of-mutton tongue and groove coordinates, and all there is processing technology loaded down with trivial details, and contact surface is unstable, drags for the problem that spearhead easily rocks or rotates difficulty.In addition, this structure, the rigidity of spring can not be too large, and no side is dragged for when spearhead rotates more difficult; On the other hand, spring rate is little, and keeping dragging for spearhead, to be in the power of erectility little, drag for spearhead upright time easily rock and secundly, affect rotate effect.
Utility model content
The utility model object is to provide a kind of card assembly that plays and drags for lance structure, drags for spearhead and locating piece contact surface is plane contact, and under the action of the spring, dragging for spearhead can keep good erectility, Problems existing in solution background technology.
The technical solution of the utility model is:
A kind of card assembly that plays drags for lance structure, comprise and drag for spearhead, axis of rotation, locating piece, spring and drag for lance seat, drag for spearhead and drag for lance seat hinged by axis of rotation, described dragging in lance seat is provided with spring mounting hole and locating piece installing hole, locating piece mounting hole site is above spring mounting hole, spring is located in spring mounting hole, and locating piece is located in locating piece installing hole, and locating piece upper surface is plane contact with dragging for spearhead bottom surface.
Described to drag for longitudinal section bottom spearhead be trapezoidal, and dragging for spearhead bottom surface is plane, drags for spearhead two bottom sides and is provided with inclined-plane.
Described spearhead lower end of dragging for is provided with junction plate one, and junction plate one is provided with rotary shaft hole one, described in drag for lance seat upper end and be provided with the junction plate two matched with junction plate one, junction plate two is provided with the rotary shaft hole two matched with rotary shaft hole one.
Adopt the utility model, drag for spearhead and be kept upright under the action of the spring.To dragging for the moment of spearhead applying perpendicular to axis of rotation, locating piece moves down, and spring compresses further, drag for spearhead bottom surface to become line face with locating piece upper surface plane-plane contact and contact, reduce the frictional force in rotary course, after dragging for the inclined-plane bottom spearhead, drag for spearhead to put in place rapidly, complete rotation in 90 °.
The beneficial effects of the utility model are: drag for spearhead and locating piece contact surface is plane, drag for the erectility that spearhead can keep good under the action of the spring; When dragging for spearhead rotation, plane-plane contact becomes the contact of line face, and only need overcome the frictional force of dragging between spearhead and locating piece just can will drag for spearhead half-twist.
