Description

Special type guard plate
Technical field
the present invention relates to vertical drilling backplate technical field of tools, is a kind of special type guard plate.
Background technology
vertical drilling system collects mechanical, electrical, liquid integrated downhole closed loop drilling tool, and being that the revolutionary character of conventional anti-oblique technology breaks through, is a cutting edge technology of our times drilling applications.This instrument can realize initiatively anti-oblique at easy deviation strata, greatly liberate the pressure of the drill, improve rate of penetration, the external monopolization to this technology broken by the vertical drilling system instrument of domestic independent research, domestic drilling applications is allowed technically to be in international most advanced level at this, backplate is the indispensable parts of vertical drilling system instrument, and the working effect of existing backplate in vertical drilling system tool work process is not very good, because vertical drill tools well straightening pushes away the borehole wall by backplate, the Different Strata borehole size that same drill bit gets out alters a great deal, the limited angle that common backplate opens, the drilling well needs that well amplification degree is larger can not be met.
Summary of the invention
the invention provides a kind of special type guard plate, overcome the deficiency of above-mentioned prior art, it effectively can solve the problem that existing common backplate can not meet the larger drilling well needs of well amplification degree.
technical scheme of the present invention is realized by following measures: a kind of special type guard plate, comprises left backplate and right backplate, the right-hand member of left backplate and the left end of right backplate hinged, the left part of left backplate and the right part of right backplate are distributed with installing hole.
here is the further optimization and/or improvements to foregoing invention technical scheme:
the right-hand member of above-mentioned left backplate can have right pin-and-hole, and the left end of right backplate has left pin-and-hole, is set with bearing pin in left pin-and-hole, and the front portion of bearing pin is sleeved in right pin-and-hole.
the front side left part of above-mentioned right backplate can be fluted, and left pin-and-hole is positioned at concave station, and the right part of left backplate is sleeved in concave station.
above-mentioned right pin-and-hole can be slotted hole.
above-mentioned right pin-and-hole can be opening U-shaped hole to the right, and the right-hand member of left backplate is installed with end cap, and end cap left end has the opening corresponding with the right pin-and-hole ending cover hole taken the shape of the letter U left.
can adjusting pad be installed with between the right-hand member of above-mentioned left backplate and end cap left end, the adjusting pad of corresponding right pin-and-hole position has through hole.
above-mentioned left backplate, adjusting pad and end cap are connected and fixed by bolt and link together.
reasonable and compact in structure of the present invention, easy to use, its by left backplate and right backplate hinged, thus realize the change of multi-angle scope, by right pin-and-hole being set to slotted hole or abutting end cap bore is oval hole shape, all can increase its angle excursion, thus meet the larger drilling well needs of well amplification degree.
Accompanying drawing explanation
accompanying drawing 1 is that the master of preferred embodiment looks sectional structure schematic diagram.
accompanying drawing 2 is the partial enlargement structural representation of accompanying drawing 1 at A place.
coding in accompanying drawing is respectively: 1 is left backplate, and 2 is right backplate, and 3 is installing hole, and 4 is right pin-and-hole, and 5 is bearing pin, and 6 is end cap, and 7 is ending cover hole, and 8 is adjusting pad, and 9 is through hole, and 10 is concave station, and 11 is bolt.
Detailed description of the invention
the present invention by the restriction of following embodiment, can not determine concrete embodiment according to technical scheme of the present invention and actual conditions.
in the present invention, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the invention will be further described:
as shown in accompanying drawing 1,2, this special type guard plate comprises left backplate 1 and right backplate 2, the right-hand member of left backplate 1 and the left end of right backplate 2 hinged, the left part of left backplate 1 and the right part of right backplate 2 are distributed with installing hole 3.In use, by installing hole 3 left backplate 1 and right backplate 2 be all fixed on the body hanging down and bore, left backplate 1 and right backplate 2 hinged, can make to form different angle between it, thus adapt to the drilling well needs of Different Strata.
according to actual needs, above-mentioned special type guard plate can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2, the right-hand member of left backplate 1 has right pin-and-hole 4, and the left end of right backplate 2 has left pin-and-hole, is set with bearing pin 5 in left pin-and-hole, and the front portion of bearing pin 5 is sleeved in right pin-and-hole 4.
as shown in accompanying drawing 1,2, the front side left part fluted 10 of right backplate 2, left pin-and-hole is positioned at concave station 10, and the right part of left backplate 1 is sleeved in concave station 10.Right backplate 2 above concave station 10 can realize left backplate 1 spacing what rotate around bearing pin 5.
as shown in accompanying drawing 1,2, right pin-and-hole 4 is slotted hole.Slotted hole can expand its angular range.
as shown in accompanying drawing 1,2, right pin-and-hole 4 is opening U-shaped hole to the right, and the right-hand member of left backplate 1 is installed with end cap 6, and end cap 6 left end has the opening corresponding with right pin-and-hole 4 ending cover hole 7 taken the shape of the letter U left.Complete oval hole shape can be formed by ending cover hole 7 and right pin-and-hole 4, bearing pin 5 be moved left and right in-between, thus expands its angular range.
as shown in accompanying drawing 1,2, between the right-hand member of left backplate 1 and end cap 6 left end, be installed with adjusting pad 8, the adjusting pad 8 of corresponding right pin-and-hole 4 position has through hole 9.Increase adjusting pad 8, can be made it and the slotted hole that formed between ending cover hole 7 and right pin-and-hole 4 longer, the thickness of adjusting pad 8 can be rotated according to demand, make it have suitable angular range.
as shown in accompanying drawing 1,2, left backplate 1, adjusting pad 8 and end cap 6 are connected and fixed by bolt 11 and link together.
above technical characteristic constitutes most preferred embodiment of the present invention, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
