For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0042] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] Reference Figure 1 to Figure 8 , which is the first embodiment of the utility model, proposes a drill rod swing arm manipulator for loading and unloading a drill rod 1, comprising:

[0044] Rotate the main body 2;

[0045] A supporting pendulum 3 is provided on the rotating body 2. The supporting pendulum 3 is used to support the drill rod 1. When the rotating body 2 rotates, the drill rod 1 is driven to approach the center of the wellhead.

[0046] In this embodiment, this scheme utilizes a structure similar to a manipulator to make the rotating body 2, that is, the rotating rod, drive the supporting pendulum 3 to rotate, thereby realizing the operation of automatic loading and unloading of the drill rod 1. The supporting pendulum 3 rotates with the rotating body 2, and at the same time, it plays the role of supporting the drill rod 1. The supporting form can adopt an open groove to clamp the drill rod 1 or an active clamping cylinder, etc., thereby replacing the workers to load and unload the drill rod 1, which not only relieves the workers from the heavy and harsh work, but also is convenient and simple to operate, fast to load and unload, high in efficiency, and speeds up the construction progress. At the same time, a rotating cylinder is installed at the end of the rotating body 2 to provide power. Compared with the swing arm cylinder that directly and independently controls the swing of the supporting pendulum 3, the rotating cylinder is smaller in size and occupies less space, which is suitable for drilling rigs with compact structure.

[0047] During operation, the supporting pendulum 3 is first driven by the rotating body 2 to avoid the center position of the wellhead. After the drill pipe 1 is hoisted in, the supporting pendulum 3 supports the drill pipe 1, the rotary cylinder rotates, and the drill pipe 1 rotates toward the center position of the wellhead. When the center of the drill pipe 1 is aligned with the center of the wellhead, the rotary cylinder stops working, and the power head can unscrew the drill pipe 1.

[0048] Furthermore, the rotating body 2 is cylindrical, and there are two supporting pendulum members 3, and the two supporting pendulum members 3 are arranged at intervals along the length direction of the rotating body 2.

[0049] In this embodiment, since the drill rod 1 is relatively long, in order to ensure that the supporting pendulum 3 stably supports the drill rod 1 and prevent the drill rod 1 from shaking during loading and unloading, which may easily cause safety accidents, two supporting pendulums 3 are used that are arranged along the length direction of the rotating body 2. 2. This structure vertically loads and unloads the drill rod 1. The rotary cylinder rotates to rotate the upper and lower supporting pendulums 3, which are connected to the center of the drill rod 1. The power faucet is used for centering, which is convenient for loading and unloading, and there is no need to manually align the drill rod 1 joint.

[0050] Furthermore, the supporting ornament 3 has a bending portion 301 at one end, and further comprises:

[0051] The rear clamping member 4 is movably disposed on the supporting swing member 3 , and the rear clamping member 4 moves closer to or away from the bending portion 301 , and a clamping area 5 is formed between the rear clamping member 4 and the bending portion 301 .

[0052] In the present embodiment, in the specific application process, in order to better support and clamp the heavier drill rod 1 and prevent it from escaping from the manipulator, the supporting swing member 3 is set to be L-shaped, and one end of the supporting swing member 3 has a bending portion 301, which can play a certain limiting role. At the same time, a rear clamping member 4 that can be actively moved is installed on the supporting swing member 3, which can be achieved by a clamping cylinder. After the rear clamping member 4 moves, the drill rod 1 can be smoothly clamped in the clamping area 5 formed by the bending portion 301 and the rear clamping member 4. Compared with the form of an open groove with a size set in advance, the above structure is suitable for various types of drill rods 1. The position of the rear clamping member 4 after the upper swing arm is clamped can be adjusted to adapt to the outer diameters of drill rods 1 of multiple sizes.

[0053] Furthermore, it also includes:

[0054] The front clamping member 6, the bending portion 301 has the front clamping member 6, the clamping area 5 is formed between the rear clamping member 4 and the front clamping member 6, the rear clamping member 4 moves closer to or away from the front clamping member 6, and the front clamping member 6 and the rear clamping member 4 both have a clamping arc surface 7.

[0055] In this embodiment, a front clamping member 6 is further detachably mounted on the bending portion 301 to facilitate later maintenance. At the same time, the front and rear clamping members 4 both have a clamping arc surface 7, so that when clamping the drill rod 1, it can better adapt to its arc-shaped outer surface.

[0056] Furthermore, the end of the supporting swing member 3 away from the rotating body 2 has the bending portion 301, and further includes:

[0057] The first limiting portion 8 is arranged to be stationary relative to the rotating body 2 and is located at one side of the bending portion 301 . The first limiting portion 8 is used to limit the rotation of the rotating body 2 .

[0058] Furthermore, there are two first limiting portions 8 , and both of the two first limiting portions 8 are located between the two supporting ornaments 3 .

[0059] In this embodiment, the first limiting portion 8 rotates with the rotating body 2. After the supporting pendulum 3 drives the drill pipe 1 to the center of the wellhead, the first limiting portion 8 can be abutted against the derrick column 12 to limit the rotation angle of the rotating body 2. At the same time, it is adjusted to ensure that the joint of the drill pipe 1 is facing the center of the wellhead. The two first limiting portions 8 are used at the same time to provide a more comprehensive limiting effect to adapt to longer drill pipes 1.

[0060] Furthermore, it also includes:

[0061] The mounting seat 9 has a first through hole 901 and a second through hole 902, and the rotating body 2 passes through the first through hole 901, and further includes:

[0062] The position adjusting member 10 is adjustably disposed in the second through hole 902 , and the first limiting portion 8 is fixedly disposed on the position adjusting member 10 .

[0063] In this embodiment, in order to further improve the accuracy of the limiting effect and facilitate installation, a mounting seat 9 is provided and installed on the rotating body 2 using the first through hole 901. At the same time, a position adjustment member 10 is adjustable in the second through hole 902 of the mounting seat 9. The position of the first limiting portion 8 fixed thereon is adjusted by adjusting its position, thereby ensuring that the drill pipe 1 joint is adjusted to face the center of the wellhead.

[0064] Furthermore, the axial direction of the second through hole 902 is perpendicular to the axial direction of the first through hole 901, and the supporting pendulum 3 has a second limiting portion 302 at one end close to the rotating body 2, and the first limiting portion 8 and the second limiting portion 302 are arranged at intervals, and the first limiting portion 8 and the second limiting portion 302 are both buffer pads, and the second limiting portion 302 is used to limit the rotation of the rotating body 2.

[0065] In this embodiment, the second through hole 902 is set axially perpendicular to the first through hole 901, so as to facilitate the smooth operation of the entire manipulator and adjust the position of the first limit portion 8 to the maximum extent to ensure the adjustment accuracy; at the same time, a second limit portion 302 is provided at one end of the supporting pendulum 3 close to the rotating body 2. When the drill pipe 1 is removed, the rotating body 2 also needs to rotate away from the center of the wellhead. This action also requires a limiting effect. Therefore, when the second limit portion 302 abuts against the derrick column 12, it means that it is in place and the drill pipe 1 can be removed.

[0066] Furthermore, it also includes:

[0067] The fixed bearing seat 11, the rotating body 2 rotates relative to the fixed bearing seat 11, the supporting pendulum 3 is located between the fixed bearing seat 11 and the mounting seat 9, and after the rotating body 2 rotates, the first limiting portion 8 is used to abut the derrick column 12, or the second limiting portion 302 is used to abut the derrick column 12.

[0068] Furthermore, it also includes:

[0069] A shield 13, wherein the shield 13 is disposed on the fixed bearing seat 11, an elastic region 14 is formed between the shield 13 and the fixed bearing seat 11, and one end of the rotating body 2 passes through the fixed bearing seat 11 and is located in the elastic region 14;

[0070] A support sleeve 15, wherein the support sleeve 15 is sleeved on one end of the rotating body 2 and is located in the elastic area 14;

[0071] An elastic member 16 , one end of which is connected to the support sleeve 15 , and the other end of which is connected to the shield 13 , is located in the elastic region 14 .

[0072] In this embodiment, in order to stably install the entire manipulator and provide stable support, the fixed bearing seat 11 plays the above-mentioned role. During operation, the fixed bearing seat 11 can be welded on the drilling rig, and the rotating body 2 rotates relative to the fixed bearing seat 11. At the same time, a buffer device is also installed at the top of the rotating body 2 to provide a certain buffer space for loading and unloading the drill pipe 1 and protect the threaded threads at the joint of the drill pipe 1. Specifically, the top position of the drill pipe 1 is a tapered thread. When the top drive drives the drill pipe 1, the two will have a connection process. If there is no buffer device, the two will collide hard, resulting in a broken buckle. The purpose of the buffer device is to unload force, so a shield 13 and an elastic member 16 are added. The shield 13 is fixedly arranged like the fixed bearing seat 11, and the remaining components have a certain amount of activity. The top drive is pressed down to drive the entire manipulator to move downward, thereby realizing force unloading. The entire process is realized by the elastic member 16 in the elastic area 14. One end of the elastic member 16 is connected to the fixed shield 13, and the other end is connected to the rotating body 2 through the support sleeve 15, thereby realizing that the rotating body 2 has a certain amount of activity.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
