Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The following description, in contrast to the meanings of the components in the specification, such as "plurality" means at least two, such as two, three, etc., and unless otherwise specifically limited, in the present invention, whether a plurality is at least two, or at least three, is intended to mean at least two

As shown in fig. 1 to 8, the inclined hole seat 100 for a gas lift reverse circulation drill according to an embodiment of the present invention includes a lower seat 1, an upper seat 2, and an adjustment assembly 3.

The lower seat 1 is provided with an opening for the sleeve to pass through. The upper seat 2 is provided with a first through hole 21 for the bushing to pass through, the upper seat 2 has a first end (shown as the rear end of the upper seat 2 in fig. 1) and a second end (shown as the front end of the upper seat 2 in fig. 1) opposite to each other, and the first end of the upper seat 2 is pivotally connected with the lower seat 1.

The second end of upper seat 2 and lower seat 1 are connected by an adjustment assembly 3 for adjusting the pivot angle between upper seat 2 and lower seat 1.

According to the inclined hole base 100 of the embodiment of the utility model, the upper base 2 is pivotally connected with the second end of the lower base 1, so that the upper base 2 can rotate by taking the second end of the lower base 1 as an end point, and further, an inclination angle is formed between the upper base 2 and the lower base 1, the first end of the upper base 2 is connected with the lower base 1 through the adjusting assembly 3, and the included angle between the upper base 2 and the lower base 1 is adjusted by adjusting the length of the adjusting assembly 3 (the length of the adjusting assembly 3 from the second end of the upper base 2 to the lower base 1). Wherein, the longer the length of the adjusting component 3, the larger the included angle between the upper seat 2 and the lower seat 1. Wherein, the included angle between the upper seat 2 and the lower seat 1 does not exceed 90 degrees.

It will be appreciated that when it is desired to perform a drilling operation in a sloped environment (a slope), the casing and the drilling machine (a gas lift reverse circulation drilling machine, etc.) need to be coaxial, it is necessary to adjust the length of the adjustment assembly 3 to make the drilling machine mounted on the upper housing 2 coaxial with the casing. Wherein the adjusting assembly 3 can be driven by a pneumatic cylinder, a hydraulic cylinder, a motor, etc.

Therefore, the inclined hole seat 100 according to the embodiment of the present invention has the advantages of simple structure, reduced error caused by the levelness of the installation surface, and wide application range.

In some embodiments, the adjusting assembly 3 includes a first connecting member 31, a second connecting member 32, and a limiting member 33, a first end of the first connecting member 31 is connected to the upper base 2, a second end of the second connecting member 32 is connected to the lower base 1, the first connecting member 31 is slidably sleeved in the second connecting member 32, and the limiting member 33 is used for preventing the first connecting member 31 and the second connecting member 32 from being disengaged from each other.

According to the inclined hole base 100 of the embodiment of the utility model, the first connecting member 31 is sleeved in the second connecting member 32 and can slide in the second connecting member 32, and the first connecting member 31 is prevented from being separated from the second connecting member 32 by the limiting member 33. The distance between the second end of upper housing 2 and lower housing 1 is adjusted by sliding first link 31 in second link 32. Wherein the first connecting member 31 can be driven by a driving device, such as a pneumatic cylinder, a hydraulic cylinder, a motor, etc.

In some other embodiments, the first connecting member 31 and the second connecting member 32 may also form a telescopic structure, and the first connecting member 31 and the second connecting member 32 are locked by the limiting member 33.

In some embodiments, the upper end of the first connecting member 31 is pivotally connected to the upper seat 2, and the first connecting member 31 is provided with a second through hole 311 that penetrates the first connecting member 31 along the length direction of the first connecting member 31.

The lower end of the second connecting piece 32 is pivotally connected with the lower seat 1, a third through hole 321 which penetrates through the second connecting piece 32 along the length direction of the second connecting piece 32 is arranged on the second connecting piece 32, and the third through hole 321 is at least opposite to part of the second through holes 311;

the limiting member 33 sequentially passes through the third through hole 321 and the second through hole 311 to prevent the first connecting member 31 and the second connecting member 32 from being separated from each other.

According to the inclined hole seat 100 of the embodiment of the utility model, the first connecting piece 31 is pivotally connected with the upper seat 2, and the second connecting piece 32 is pivotally connected with the lower seat 1, so that the first connecting piece 31 and the second connecting piece 32 can be conveniently sleeved and stored. Specifically, when the angle correction is not required, the first link 31 and the second link 32 may be rotated to both sides to reduce the distance between the upper seat 2 and the lower seat 1. When the first link 31 and the second link 32 are deflected to both sides for storage, the sum of the heights of the first link 31 and the second link 32 in the up-down direction is lower than the distance between the upper seat 2 and the lower seat 1.

The limiting member 33 sequentially passes through the third through hole 321 and the second through hole 311 to limit the separation of the first connecting member 31 and the second connecting member 32. And the distance between the second end of the upper seat 2 and the lower seat 1 can be adjusted by adjusting the length of the limiting member 33. Specifically, when the limiting member 33 passes through the third through hole 321 and the second through hole 311, the distance between the upper edge of the third through hole 321 and the limiting member 33 is the adjustable distance. The number of the limiting members 33 can be plural, and the distance between the second end of the upper seat 2 and the lower seat 1 can be finely adjusted by increasing and decreasing the number of the limiting members 33.

In some embodiments, the first connector 31 further includes a first support detachably disposed in the second through hole 311 for dividing the second through hole 311 into a first sub through hole 3111 and a second sub through hole 3112, and the third through hole 321 corresponds to the second sub through hole 3112.

The first connecting member 31 further includes a second supporting member detachably disposed in the first sub-through hole 3111, a first end of the second supporting member is connected to the first supporting member, and a second end of the second supporting member is connected to an inner sidewall of the first sub-through hole 3111. The second support plate 313 is provided in plurality.

According to the inclined hole seat 100 of the embodiment of the utility model, the first supporting member can share part of the pressure for the second connecting member 32, specifically, as shown in fig. 3 to 8, when the first connecting member 31 and the second connecting member 32 are matched, when the limiting member 33 passes through the third through hole 321 and the second through hole 311, the pressure is completely borne by the third through hole 321, at this time, the first supporting member divides the second through hole 311 into the first sub through hole 3111 and the second sub through hole 3112, and the height of the second sub through hole 3112 is the same as the height of the third through hole 321, at this time, the pressure is shared by the third through hole 321 and the first supporting plate 312, so that the service life of the second connecting member 32 can be increased. The second supporting member is disposed in the first sub through hole 3111 and connected to the inner walls of the first supporting member and the first sub through hole 3111, respectively, so as to support the first supporting plate 312 through the second supporting plate 313, thereby further enhancing the strength of the first supporting plate 312.

In some embodiments, the lower seat 1 comprises a first bracket 11, a second bracket 12, a third bracket 13 and a fourth bracket 14, the first bracket 11, the second bracket 12, the third bracket 13 and the fourth bracket 14 being connected end to end in sequence and defining an opening.

The lower base 1 further includes a fixing member 15, and the fixing member 15 is used to fix the first bracket 11, the second bracket 12, the third bracket 13, and the fourth bracket 14.

According to the inclined hole seat 100 provided by the embodiment of the utility model, the lower seat 1 is formed by sequentially connecting and splicing the first support 11, the second support 12, the third support 13 and the fourth support 14 end to end, and two adjacent supports are fixed through the fixing piece 15, so that the integral strength is enhanced, and the service life of the lower seat 1 is prolonged.
