Adopt the frock is dismantled to drilling rod that above-mentioned structure set up, can install on stabilizer bar 100 and adjacent drilling rod 101 with it through first cardboard 200 and second cardboard 300, and through card square structure cooperation drilling rod 101, block concave position 103 on the stabilizer bar 100 realizes cardboard and drilling rod 101, stabilizer bar 100's angle is fixed, rethread control mechanism controls first cardboard 200, second cardboard 300 opens relatively or receives, can drive drilling rod 101 and stabilizer bar 100 and carry out relative rotation, accomplish the separation of threaded connection department. Compared with the traditional process, the production cost can be effectively reduced, the operation efficiency is improved, and the practicability is high.

In actual operation, the specific connection object of the first clamping plate 200 and the second clamping plate 300 can be flexibly changed, for example, the first clamping plate 200 can be installed on the drill rod 101, the corresponding second clamping plate 300 is installed on the stabilizer bar 100, the first clamping plate 200 can be installed on the stabilizer bar 100 in reverse, and the corresponding second clamping plate 300 is installed on the drill rod 101.

In some embodiments of the present invention, each of the first clamping plate 200 and the second clamping plate 300 is provided with a clamping structure adapted to the drill rod 101 or the stabilizer bar 100. Because the structures of the drill rod 101 and the stabilizer bar 100 are substantially the same, in actual production, the first clamping plate 200 and the second clamping plate 300 may adopt the same structural design, that is, the first clamping plate 200 and the second clamping plate 300 may have the same structure, and the clamp structures arranged thereon are also the same. The clamp structure is adopted, so that the first clamping plate 200 and the second clamping plate 300 can be directly installed on the drill rod 101 and the stabilizer bar 100 from the outer sides of the drill rod 101 and the stabilizer bar 100, the drill rod 101 or the stabilizer bar 100 does not need to be sleeved in from one end of the drill rod 101 or the stabilizer bar 100, and the practicability is higher.

In some embodiments of the present invention, the clamp structure is provided with a holding arm 400 adapted to the drill rod 101 or the stabilizer bar 100. Taking the first clamping plate 200 as an example, one end of the arm 400 is hinged to the first clamping plate 200, the other end is detachably connected to the first clamping plate 200, one side of the arm 400 close to the first clamping plate 200 is a semi-cylindrical structure matched with the surface profile of the drill rod 101 and the surface profile of the stabilizer bar 100, and the area between the two ends of the arm 400 of the first clamping plate 200 is a semi-cylindrical structure matched with the surface profile of the drill rod 101 and the surface profile of the stabilizer bar 100, so that the drill rod 101 or the stabilizer bar 100 is clamped when the tail end of the arm 400 is connected to the first clamping plate 200. The cubic structure is disposed inside the arm 400 and a portion of the first card board 200 close to the arm 400 (i.e., the portion of the semi-cylindrical structure described above).

The detachable connection between the arm 400 and the first clamping plate 200 can be realized by adopting a bolt connection and fixation mode, and can also be realized by adopting a buckling connection mode, a pin connection mode and other modes disclosed by the prior art.

Moreover, it can be understood that, because the drill rod 101 and the stabilizer bar 100 are circumferentially provided with the plurality of engaging concave portions 103, and the first clamping plate 200 and the second clamping plate 300 only need to drive the drill rod 101 and the stabilizer bar 100 to rotate, so that the work can be realized, the square-clamping structure can also be only arranged on the inner side of the arm 400 or on a portion of the corresponding clamping plate close to the arm 400, and this way can also realize the angle fixation between the clamping plate and the corresponding drill rod 101 or stabilizer bar 100.

When considering embracing arm 400 and embracing drilling rod 101 or stabilizer bar 100, still there is the clearance between the two, in order to avoid the clearance to influence the normal work that the frock was dismantled to the drilling rod, eliminate simultaneously or reduce the impact that produces because of the existence in clearance when control mechanism control first cardboard 200, second cardboard 300 rotated the utility model discloses an in some embodiments, be provided with locking bolt 402 on embracing arm 400, locking bolt 402's tip is located the inboard of embracing arm 400. When the drill rod 101 or the stabilizer bar 100 is mounted, the locking bolt 402 may be tightened, and the drill rod 101 or the stabilizer bar 100 may be tightened by the locking bolt 402, thereby eliminating the gap. The number of the lock bolts 402 can be flexibly set as required. Because when dismantling the operation, the main part of first cardboard 200, second cardboard 300 is that control mechanism drives drilling rod 101, the stabilizer bar 100 pivoted arm of force, with the setting of locking bolt 402 on embracing arm 400, can not influence the structural strength of first cardboard 200, second cardboard 300, the practicality is strong.

In some embodiments of the present invention, the arm 400 is provided with a plurality of first lightening holes 401 uniformly along the length direction, the axes of the first lightening holes 401 are parallel to the axis of the drill rod 101, the first clamping plate 200 and the second clamping plate 300 are both provided with second lightening holes 301 between the connection with the drill rod 101 or the stabilizer bar 100 and the connection with the control mechanism, and the axes of the second lightening holes 301 are also parallel to the axis of the drill rod 101. When the first clamping plate 200 and the second clamping plate 300 are installed, the drill rod 101 and the stabilizer bar 100 are not horizontally arranged on the ground, so that hoisting is needed, and the hoisting can be effectively completed by matching with hoisting equipment through the arrangement of the first lightening holes 401 and the second lightening holes 301. Meanwhile, through experimental comparison and analysis, on the basis that the structural strength of the drill rod 101 and the stabilizer bar 100 can be met, the first clamping plate 200 and the second clamping plate 300 are heavy, high in production cost and high in carrying difficulty, and the first lightening holes 401 and the second lightening holes 301 can effectively reduce the weight and save materials, so that the production cost and the carrying difficulty are reduced to a certain extent.

Because drilling rod 101 and stabilizer bar 100 are vertical concatenation distribution, consequently first cardboard 200, second cardboard 300 are in two horizontal planes certainly, and the formation of the above-mentioned arm of force can effectively be realized through the setting of first mount pad 201, second mount pad 302 to this embodiment to realize the rotation drive of control mechanism to first cardboard 200, second cardboard 300 better.

Considering that after the relative angle changes of the first clamping plate 200 and the second clamping plate 300, the angle changes inevitably occur between the force arms formed by the first mounting seat 201 and the second mounting seat 302 and the control mechanism, for adapting to the angle changes, in some embodiments of the present invention, the first mounting seat 201 and the second mounting seat 302 are rotatably disposed on the first clamping plate 200 and the second clamping plate 300, and the rotating shafts thereof are all parallel to the axial direction of the drill rod 101. So that the first and

second mounting seats

201 and 302 eliminate interference and influence on the moment arm after the first and

second cards

200 and 300 are angularly changed. The first and

second mounting seats

201 and 302 may be rotatably mounted in any one of the structures in the prior art, and will not be described herein.

In some embodiments of the present invention, the control mechanism includes a screw rod disposed on the first mounting seat 201 and the second mounting seat 302 and a driving mechanism for driving the screw rod to rotate, and a screw thread section with an opposite spiral direction to that of the second mounting seat 302 is disposed between the screw rod and the first mounting seat 201. Therefore, only the driving mechanism is needed to control the screw rod to rotate, the first mounting seat 201 and the second mounting seat 302 can be controlled to move synchronously and reversely along the axial direction of the screw rod through the thread sections, the angle change of the first clamping plate 200 and the second clamping plate 300 is realized, and the threaded disassembly of the drill rod 101 and the stabilizer bar 100 is further realized.

The driving mechanism can adopt a hydraulic motor and also can adopt other driving structures capable of realizing the rotation of the screw rod.

Considering that the efficiency of screw drive is slower, in some embodiments of the present invention, the control mechanism is provided with hydraulic jack 502 and a hand-operated high-pressure pump connected to hydraulic jack 502. Meanwhile, a connecting rod 500 penetrates through the first mounting seat 201 and the second mounting seat 302, a double-acting hollow jack is selected for the hydraulic jack 502, one end of the connecting rod 500 is fixed on the double-acting hollow jack, the other end of the connecting rod passes through the two mounting seats in sequence, and a limiting head 501 is arranged at the tail end of the connecting rod. During operation, the double-acting hollow jack extends out to push the closest mounting base through the hand-operated high-pressure pump, and meanwhile, the limiting head 501 at the tail end is abutted to the other mounting base, so that the first mounting base 201 and the second mounting base 302 are folded and driven. In this embodiment, a strip-shaped hole may be provided on the first mounting seat 201 and the second mounting seat 302 corresponding to the connecting rod 500, wherein the axial direction of the strip-shaped hole is perpendicular to the axial direction of the drill rod 101, but the length direction of the vertical section of the strip-shaped hole is parallel to the axial direction of the drill rod 101, so that the connecting rod 500 can move up and down to adapt to the axial displacement of the drill rod 101 and the stabilizing rod 100 during the thread removal. Meanwhile, the distances between the clamping concave position 103 and the end part of the drill rod 101 and the stabilizer bar 100 produced by different manufacturers are not necessarily the same, and the distance between the first clamping plate 200 and the second clamping plate 300 can be adjusted through the arrangement of the strip-shaped hole channels, so that the application range is widened.

It will be appreciated that the hand-operated high pressure pump of the above embodiments may be replaced by other pump stations. And the control mechanism can also adopt other mechanisms which can realize the control of the two positions close to each other and far away from each other.
