[0038] See also Figures 1 to 4 As shown, Figure 1 A schematic diagram of the structure of the finger beam spacing adjustment mechanism provided in the first embodiment of the present application when the first finger beam group and the second finger beam group are not misaligned; Figure 2 A schematic diagram of the structure of the finger beam spacing adjustment mechanism provided in the first embodiment of the present application when the first finger beam group and the second finger beam group are in a misaligned state; Figure 3 A side view of the finger beam spacing adjustment mechanism provided in Example 1 of the present application; Figure 4 A schematic structural diagram of a first limit assembly or a second limit assembly of a finger beam spacing adjustment mechanism provided in Example 1 of the present application;

[0039] The present application provides a finger beam spacing adjustment mechanism for clamping a drill rod 100, comprising a first finger beam group 101 and a second finger beam group 102; the first finger beam group 101 forms a first gap 103, and the second finger beam group 102 forms a second gap 104, and the drill rod 100 can pass through the first gap 103 and the second gap 104, so that the first finger beam group 101 and the second finger beam group 102 clamp the drill rod 100; the first finger beam group 101 and the second finger beam group 102 can move relative to each other, so that the first gap 103 and the second gap 104 are misaligned along a first direction 105, that is, the spacing of the clamping space formed by the first gap 103 and the second gap 104 is adjusted, so as to clamp the drill rods 100 of different diameters.

[0040] The present application is applicable to drilling and repairing operations, especially deep well and ultra-deep well drilling operations. When a variety of drill rods 100 with different diameters (commonly used drill rods 100 have diameters of 3-1 / 2 in, 4 in, 5 in, etc.) are needed in the operation, a double-layer finger beam group is used, which is a first finger beam group 101 and a second finger beam group 102 (the first finger beam group 101 and the second finger beam group 102 are arranged along the second direction), wherein the first finger beam group 101 is formed with a first gap 103, and the second finger beam group 102 is formed with a first gap 104. A second gap 104 is formed, and the drill rod 100 can pass through the first gap 103 and the second gap 104, so that the first finger beam group 101 and the second finger beam group 102 are used to clamp the drill rod 100 of the first diameter; when it is necessary to clamp the drill rod 100 of the second diameter, the first finger beam group 101 and the second finger beam group 102 can move relative to each other, so that the first gap 103 and the second gap 104 are misaligned along the first direction 105, and can be used to clamp the drill rod 100 of the second diameter;

[0041] More specifically, in actual use, it is preferred that the length, width, and height of the first finger beam group 101 and the second finger beam group 102 are the same (the length, width, and height of the first finger beam group 101 and the second finger beam group 102 in the present application may also be different), and it is preferred that the width of the first gap 103 and the width of the second gap 104 are the same, that is, the first finger beam group 101 and the second finger beam group 102 can completely overlap, such as Figure 1 As shown, the width of the first gap 103 and the second gap 104 is H. The gap H can be used to clamp the drill rod 100 of the first diameter (large diameter). When the first finger beam group 101 and the second finger beam group 102 are moved relative to each other, the first gap 103 and the second gap 104 are misaligned, as shown in FIG. Figure 2 As shown, the relative gap for clamping the drill rod 100 becomes h at this time, and the relative gap h is used to clamp the drill rod 100 of the second diameter (the diameter of the drill rod 100 of the second diameter is smaller than the diameter of the drill rod 100 of the first diameter).

[0042] Compared with the prior art in which a single-layer finger beam group is provided, when a single-layer finger beam group is used to clamp drill rods 100 of different diameters, one or more finger beams in the single-layer finger beam group need to be rotated and removed, and then the distance between the remaining finger beams need to be adjusted to clamp more drill rods 100 of different diameters (or the finger beams can be manually replaced to change the finger beam spacing). In comparison, the present application has a simple structure, simple operation, and greatly improved work efficiency.

[0043] In this embodiment, in order to facilitate driving the first finger beam group 101 and the second finger beam group 102 to generate relative movement, the finger beam spacing adjustment mechanism further includes a driving component;

[0044] Among them, the first driving mode is: the driving component is connected to the first fixed end of the first finger beam group 101; that is, at this time, the second finger beam group 102 is fixed, and the driving component is used to drive the first finger beam group 101, so that the first finger beam group 101 and the second finger beam group 102 move relative to each other, thereby causing the first gap 103 and the second gap 104 to be misaligned, so as to be used to clamp drill rods 100 of different diameters.

[0045] The second driving mode: the driving component is connected to the second fixed end of the second finger beam group 102; that is, at this time, the first finger beam group 101 is fixed, and the driving component is used to drive the second finger beam group 102, so that the second finger beam group 102 and the first finger beam group 101 move relative to each other, thereby causing the first gap 103 and the second gap 104 to be misaligned, so as to be used to clamp drill rods 100 of different diameters.

[0046] The third driving mode: the driving component is respectively connected to the first fixed end of the first finger beam group 101 and the second fixed end of the second finger beam group 102; that is, the driving component is used to simultaneously drive the movement of the first finger beam group 101 and the second finger beam group 102, thereby realizing the relative movement of the first finger beam group 101 and the second finger beam group 102, and then causing the first gap 103 and the second gap 104 to be misaligned, so as to be used to clamp drill rods 100 of different diameters.

[0047] In this embodiment, combined with Figure 1-Figure 3 As shown, in order to ensure that the present application has a simple structure and is easy to operate, the driving assembly includes a motor 107, a worm 108 connected to the output shaft of the motor 107, a worm wheel 109 connected to the worm 108, a transmission shaft 110 connected to the worm wheel 109, a gear 111 connected to the transmission shaft 110, and a rack 112;

[0048] When the driving assembly is used to drive the first finger beam group 101, the rack 112 is set at the first fixed end of the first finger beam group 101; when the driving assembly is used to drive the second finger beam group 102, the rack 112 is set at the second fixed end of the second finger beam group 102.

[0049] The specific driving process is that the output shaft of the motor 107 can drive the worm 108 to rotate, the worm 108 can drive the worm wheel 109 to rotate, the worm wheel 109 can drive the gear 111 to rotate through the transmission shaft 110, and the gear 111 drives the first finger beam group 101 and the second finger beam group 102 to move relative to each other through the rack 112.

[0050] When the driving component drives the first finger beam group 101 and the second finger beam group 102 at the same time, there are two driving components at this time, namely the first driving component and the second driving component, wherein the first driving component is used to drive the first finger beam group 101, and the second driving component is used to drive the second finger beam group 102, the first rack in the first driving component is set on the first fixed end of the first finger beam group 101, and the second rack of the second driving component is set on the second fixed end of the second finger beam group 102.

[0051] The specific driving process is that the output shaft of the first motor on the first driving component can drive the first worm to rotate, the first worm can drive the first worm wheel to rotate, the first worm wheel can drive the first gear to rotate through the transmission shaft, and the first gear drives the first finger beam to move through the first rack; at the same time, the output shaft of the second motor on the second driving component can drive the second worm to rotate, the second worm can drive the second worm wheel to rotate, the second worm wheel can drive the second gear to rotate through the transmission shaft, and the second gear drives the second finger beam to move through the second rack, that is, the first driving component and the second driving component are used to drive the first finger beam group 101 and the second finger beam group 102 respectively, so that the first finger beam group 101 and the second finger beam group 102 move relative to each other.

[0052] In this embodiment, combined with Figure 3 The first finger beam group 101 and the second finger beam group 102 are arranged along the second direction 106, that is, the first finger beam group 101 is located below the second finger beam group 102 or the first finger beam group 101 is located above the second finger beam group 102. In this embodiment, preferably, the first finger beam group 101 is located below the second finger beam group 102.

[0053] Combination Figure 2 As shown, the first finger beam group 101 includes a plurality of first finger beams 113 arranged in parallel along the first direction 105 (it is worth noting that the first direction 105 here is perpendicular to the second direction 106), and the first gap 103 is formed between two adjacent first finger beams 113, and one ends of the plurality of first finger beams 113 are fixedly connected to form a first fixed end; the second finger beam group 102 includes a plurality of second finger beams 114 arranged in parallel along the first direction 105 (it is worth noting that the first direction 105 here is perpendicular to the second direction 106), and the second gap 104 is formed between two adjacent second finger beams 114, and one ends of the plurality of second finger beam groups 102 are fixedly connected to form a second fixed end.

[0054] Specifically, the number of the first finger beams 113 and the number of the second finger beams 114 are not specifically limited. Preferably, the number of the first finger beams 113 is the same as the number of the second finger beams 114. Of course, to improve work efficiency, the more the number of the first finger beams 113 and the second finger beams 114 is, the higher the work efficiency is.

[0055] In this embodiment, in order to ensure that when the second finger beam group 102 is driven by the driving component, the second finger beam group 102 can quickly move relative to the first finger beam group 101, a slider 116 is provided on the side wall of the first finger beam 113 facing the second finger beam 114 along the first direction 105, and specifically, a plurality of sliders 116 are arranged at intervals; a sliding groove 115 is provided on the side wall of the second finger beam 114 facing the first finger beam 113 along the first direction 105, and specifically, a plurality of sliding grooves 115 are arranged at intervals; preferably, the number of the sliders 116 is the same as the number of the sliding grooves 115, and the sliders 116 are adapted to the sliding grooves 115, and the cooperation of the sliders 116 and the sliding grooves 115 is utilized to ensure that the second finger beam group 102 can quickly move relative to the first finger beam group 101.

[0056] In this embodiment, in order to ensure that the drill rod 100 can be more stable in the first gap 103, the second gap 104 and the relative gap; a first limiting member 117 is provided on the opposite side walls of two adjacent first finger beams 113, and a first limiting groove 119 is opened on the first limiting member 117; a second limiting member 118 is provided on the opposite side walls of two adjacent second finger beams 114, and a second limiting groove 120 is opened on the second limiting member 118, and the first limiting groove 119 and the second limiting groove 120 are both used to fix the drill rod 100.

[0057] When the first finger beam group 101 and the second finger beam group 102 are arranged overlapping in the second direction 106 (preferably, the first finger beam group 101 is located below the second finger beam group 102), the drill rod 100 passes through the first limiting groove 119 and the second limiting groove 120 in sequence. At this time, the drill rod 100 is fixed simultaneously by using the first limiting groove 119 on the opposite side wall of the first finger beam 113 and the second limiting groove 120 on the opposite side wall of the second finger beam 114; when the first finger beam group 101 and the second finger beam group 102 move relative to each other in the first direction 105, the drill rod 100 passes through the relative gap. At this time, the drill rod 100 is fixed simultaneously by using the first limiting groove 119 on the single side wall of the first finger beam 113 and the second limiting groove 120 on the side wall of the second finger beam 114 opposite to the first limiting groove 119.

[0058] In this embodiment, in order to further ensure that when the first finger beam group 101 is arranged below the second finger beam group 102, the drill rod 100 passes through the first limiting groove 119 and the second limiting groove 120 in sequence to be more stable; a clamping portion 121 is arranged on the side wall of the first finger beam 113 away from the second finger beam 114, specifically, the clamping portion 121 has a fixed end and an extension end, and the fixed end forms a certain angle with the clamping end; the fixed end is fixedly arranged on the first finger beam 113, and the extension end can extend into the clamping space, and then the extension end is used to clamp the drill rod 100, and the clamping portion 121 can further limit the drill rod 100 to prevent the drill rod 100 from tilting and causing the problem of falling over, that is, the first limiting member 117, the second limiting member 118 and the clamping portion 121 are used to achieve a dual fixing effect on the drill rod 100.

[0059] In summary, the finger beam spacing adjustment mechanism of the present application has the following advantages: first, the finger beam spacing can be automatically adjusted to adapt to drill rods 100 of different diameters; second, the drill rod 100 is more securely fixed; and third, the structure is simple and the feasibility is good.
