[0002] In the field of oil and gas exploration, top drives are a widely used type of drilling equipment. These devices, which directly drive the drill string from the top of the derrick, revolutionize traditional rotary table drilling and enable a variety of drilling operations, including circulating drilling fluid, connecting stand pipes, making and breaking out, and back-reaming. The top drive is mounted on a guide rail, which is attached to the derrick via a torque-reducing beam. The torque generated by the top drive's rotation is transmitted to the guide rail and, through the torque-reducing beam, to the derrick itself.

[0003] Existing top drive anti-torque beams, such as the semi-open top drive anti-torque beam disclosed in patent application number 201620451766.6, require adjustment of the top drive guide rails after the top drive is installed or the derrick is corrected.

[0026] Example 1:

[0027] This embodiment provides a top drive guide rail correction device, such as Figure 1-Figure 4 As shown, it includes a mounting base 2, an adjusting beam 3, a transverse screw 4 and a longitudinal screw 5. Wherein, both the transverse screw 4 and the longitudinal screw 5 are provided with thread segments, and the transverse screw 4 is perpendicular to the longitudinal screw 5.

[0028] The mounting base 2 is connected to the derrick 1 via a first connecting assembly. The adjustment beam 3 is connected to the mounting base 2 via a second connecting assembly. Both ends of the transverse screw 4 are connected to the derrick 1. The derrick 1 includes a horizontal frame 11 and a vertical frame 12, with the horizontal frame 11 perpendicular to the vertical frame. The mounting base 2 is connected to the horizontal frame 11 of the derrick 1. The transverse screw 4 is parallel to the horizontal frame 11 and has both ends connected to the vertical frame 12.

[0029] The mounting base 2 is adjustably connected to the transverse screw 4 and can drive the adjusting beam 3 to move laterally along the transverse screw 4 . The adjusting beam 3 is adjustably connected to the longitudinal screw 5 and can move the adjusting beam 3 longitudinally relative to the mounting base 2 .

[0030] When in use, the top drive guide rail correction device of this embodiment uses a transverse lead screw 4 to simultaneously move the mounting base plate 2 and the adjustment beam 3 laterally relative to the derrick 1, and a longitudinal lead screw 5 to achieve longitudinal movement of the adjustment beam 3 relative to the mounting base plate 2. Since the adjustment beam 3 is connected to the top drive guide rail, the position of the top drive guide rail on the derrick 1 can be adjusted, thereby meeting the top drive guide rail correction requirements during use. Compared with the traditional correction method of hammering, the displacement can be easily controlled, and the guiding effect of the lead screw ensures more uniform force during adjustment, making the operation more time-saving and labor-saving.

[0031] It should be noted that the top drive guide rail correction device in this embodiment is equivalent to an anti-torque beam with a correction function. The mounting base 2, the adjustment beam 3, the first connecting assembly and the second connecting assembly are all components of the anti-torque beam.

[0032] As a preferred embodiment, a connecting seat 6 and a connecting block 7 are provided on the mounting base plate 2 . The connecting seat 6 is connected to the mounting base plate 2 , and the connecting seat 6 can be welded to the mounting base plate 2 .

The connecting block 7 and the connecting seat 6 can be an integrated structure. The bottom surface area of ​​the connecting block 7 is smaller than the top surface area of ​​the connecting seat 6.

[0034] The mounting base plate 2 in this embodiment is adjustably connected to the transverse screw 4 through the connecting seat 6 and the connecting block 7, and the movement of the connecting block 7 on the transverse screw 4 drives the transverse movement of the mounting base plate 2 and the adjustment beam 3.

[0035] As a preferred embodiment, a connecting groove 71 is provided on the connecting block 7 to cooperate with the transverse screw 4, and the notch of the connecting groove 71 faces the side away from the connecting seat 6 to facilitate the transverse screw 4 to enter the connecting groove 71 from the notch to connect with the connecting block 7.

[0036] The connecting groove 71 is open on two opposite sides in the transverse direction. The connecting groove 71 limits the transverse screw 4 in the longitudinal direction, so that the connecting block 7 can only move in the transverse direction along the transverse screw 4.

[0037] The transverse screw 4 is arranged through the connecting groove 71 and a transverse adjustment nut 41 is respectively provided on the transverse screw 4 on both sides of the connecting block 7.

[0038] When performing lateral adjustment, adjust the lateral adjustment nut 41 and the gasket 42 to be distributed on both sides of the connecting block 7. By rotating the lateral adjustment nut 41, the anti-torque beam is pushed to move horizontally. After adjusting to the appropriate position, the lateral adjustment nut 41 on the other side is also locked.

The screw adjusting seat 31 is arranged on the upper side of one end away from the top drive guide rail return plate 32.

[0041] One end of the longitudinal screw 5 passes through the screw adjustment seat 31 and the other end is hinged to the connecting block 7 . The longitudinal screw 5 can rotate up and down relative to the connecting block 7 .

[0042] Longitudinal adjustment nuts 51 are respectively provided on the longitudinal screws 5 on both sides of the screw adjustment seat 31 .

[0043] like Figure 1 and Figure 2 As shown, when performing longitudinal adjustment, rotate the longitudinal adjustment nut 51 to push the adjustment beam 3 forward and backward. After adjusting to the appropriate position, tighten the longitudinal adjustment nut 51 on the other side. The two longitudinal adjustment nuts 51 lock the adjustment beam 3 in the front and rear directions.

[0044] As a preferred embodiment, the connecting base 6 includes a horizontal plate 62 and two side plates 61. The bottom ends of the two side plates 61 are connected to the mounting base 2 and the top ends thereof are vertically connected to the two sides of the horizontal plate 62.

[0045] The connecting block 7 is connected to the transverse plate 62. A longitudinal through-hole 63 is formed between the two side plates 61 and the transverse plate 62. The adjusting beam 3 is arranged through the through-hole 63. The connecting seat 6 also guides the longitudinal movement of the adjusting beam 3.

[0046] As a preferred embodiment, two longitudinally extending limiting bars 22 are provided on the mounting base 2. A sliding groove 23 is formed between the two limiting bars 22, which is compatible with the adjusting beam 3. The adjusting beam 3 is disposed within the sliding groove 23.

[0047] A reinforcing rib 64 is provided between the side plate 61 and the limiting strip 22, and the reinforcing rib 64 is connected to the outer side of the connecting seat 6. The reinforcing rib 64 is welded to the connecting seat 6 and the mounting base 2, and the reinforcing rib 64 makes the connection between the connecting seat 6 and the mounting base 2 more firmly and the stress strength is higher.

[0048] As a preferred embodiment, the first connecting assembly includes multiple sets of base plate connecting assemblies. In this embodiment, four sets of base plate connecting assemblies are provided, with two sets of base plate connecting assemblies provided on both sides of the connecting base 6, respectively. This balances the forces on both sides of the mounting base 2 and enhances the stability of the connection.

[0049] The baseplate connection assembly includes two first holddowns 81 and two first bolts 82. The mounting baseplate 2 is positioned against the crossbars of the derrick 1. The two first holddowns 81 are located on the upper side of the mounting baseplate 2 and the lower side of the crossbars of the derrick 1, respectively, and are arranged longitudinally. Two first bolts 82 connect the upper and lower first holddowns 81, one on each side of the crossbars of the derrick 1. Each set of baseplate connection assemblies forms a connection hole for the crossbars to pass through, securely securing the mounting baseplate to the crossbars.

[0050] As a preferred embodiment, a plurality of connection notches 21 are provided on both sides of the mounting base plate 2. The first bolts 82 can be moved into the connection notches 21 to connect the mounting base plate. The provision of the connection notches 21 can facilitate the fixed connection of the first bolts 82 and improve operational efficiency.

[0051] As a preferred embodiment, the second connection assembly includes multiple groups of adjustment beam connection assemblies. The multiple groups of adjustment beam connection assemblies are evenly distributed on the adjustment beam 3 on both sides of the front and rear sides of the connection seat 6. The second connection assembly includes an even number of adjustment beam connection assemblies.

[0052] The adjusting beam connection assembly includes a second pressure strip 91 and two second bolts 92. The second pressure strip 91 is horizontally pressed on the adjusting beam 3. The two second bolts 92 pass through the second pressure strip 91 on both sides of the adjusting beam 3 and are connected to the limiting strip 22 of the mounting base 2.

[0053] As a preferred embodiment, the second connecting assembly includes two groups of adjusting beam connecting assemblies, which are respectively connected to the adjusting beam 3 and the mounting base 2 on both sides of the connecting seat 6, so that the front and rear sides of the adjusting beam 3 are evenly stressed and the connection is firm.

[0054] When the top drive guide rail correction device of this embodiment needs to correct the top drive guide rail, the transverse screw is connected to the screw seats of the two vertical frames and fixed at both ends. The transverse adjustment nuts 41 and washers 42 are adjusted to be distributed on both sides of the connecting block 7. The first bolt 82 is loosened. By rotating the transverse adjustment nut 41, the anti-torque beam is pushed horizontally. After adjusting to the appropriate position, the transverse adjustment nut 41 on the other side is also tightened. The two transverse adjustment nuts 41 lock the connecting block 7 in the horizontal direction. The first bolt 82 is then tightened. The second bolt 92 is loosened. The longitudinal adjustment nut 51 is then rotated to push the adjustment beam 3 forward and backward. After adjusting to the appropriate position, the longitudinal adjustment nut 51 on the other side is tightened. The two longitudinal adjustment nuts 51 lock the adjustment beam 3 in the forward and backward direction. The second bolt 92 is tightened to complete the top drive guide rail correction operation.

[0055] Correcting the top drive guide rail is a relatively complex operation. It is not difficult, but it requires repeatedly moving the top drive up and down to achieve a better alignment effect. The traditional method of correcting the top drive guide rail by hammering generally takes 3-4 hours. Using the top drive guide rail correction device of this embodiment, the operation can be completed in 1 hour. Based on the fuel consumption of approximately RMB 1,875 per hour, each correction of the guide rail can save RMB 3,750-5,625, effectively reducing investment costs and improving work efficiency.

[0056] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
