Description

Technical Field

[0001] This utility model relates to the field of drill pipe technology, specifically to a rod-mounting mechanism with flipping and high stability. Background Technology

[0002] Drill pipes are typically used to connect surface equipment such as drilling rigs to drilling equipment or bottom hole systems located at the bottom of the well, and are used in conjunction with drill bits for drilling operations. In the oil production industry, oil drill pipes are an indispensable and important tool in oil drilling operations. Because oil drilling depths are typically quite deep, as the drilling depth increases, multiple drill pipes need to be connected in sequence to ensure normal drilling operations.

[0003] The inventors discovered that at least the following problems remain unresolved in the prior art: during the drill rod connection process, workers need to flip the drill rod to a vertical position for connection. During the flipping connection process, the drill rod is prone to shaking, and it is difficult to align the two sets of drill rods, which affects the installation efficiency of the drill rod.

[0004] Therefore, we propose an upper rod mechanism with flipping capability and high stability, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an upper rod mechanism that has a flipping function and high stability, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotating and highly stable upper rod mechanism, comprising a fixed frame, a positioning sleeve rotatably connected to the inner side of the fixed frame, and a clamping block movably connected to the inner side of the positioning sleeve, the number of clamping blocks being three sets; a rotating mechanism for rotating the positioning sleeve, the rotating mechanism including a servo motor, a first connecting rod and a second connecting rod respectively horizontally fixedly installed on both sides of the positioning sleeve, the shaft end of the servo motor being fixedly connected to the end of the first connecting rod away from the positioning sleeve; an adjusting mechanism for adjusting the clamping block, the adjusting mechanism including an air guide groove, three sets of piston grooves evenly opened on the inner side of the positioning sleeve, a piston slidably connected to the inner side of the piston groove, one end of the clamping block placed inside the piston groove being fixedly connected to the middle of the piston, the air guide groove being opened inside the positioning sleeve, and an air inlet pipe and an air outlet pipe being horizontally fixedly installed inside the second connecting rod.

[0007] As an optional solution to the technical solution of this application, the air outlet end of the air inlet pipe and the air inlet end of the air outlet pipe are both connected to the air guide groove, and a solenoid valve is provided inside the air inlet pipe and the air outlet pipe.

[0008] As an optional solution to the technical solution of this application, the clamping block is movably connected to the piston groove, and the dimensions of the clamping block and the piston groove are matched.

[0009] As an optional solution to the technical solution of this application, the air guide groove is annular and is connected to three sets of piston grooves.

[0010] As an optional solution to the technical solution of this application, the first connecting rod and the second connecting rod on both sides of the positioning sleeve are rotatably connected to both sides of the fixing frame through bearings, and the servo motor is fixedly connected to the outside of the fixing frame.

[0011] As an optional solution to the technical solution of this application, the fixing frame is U-shaped, and an installation groove is provided through the middle of the bottom end of the fixing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning sleeve can position the horizontal drill rod; the air inlet pipe is connected to the air guide groove, which can inflate the three sets of piston grooves; the piston can push one end of the three sets of clamping blocks out of the piston groove and press against the drill rod surface inside the positioning sleeve, further stabilizing the drill rods of different diameters inside the positioning sleeve; the servo motor is controlled to work, and the positioning sleeve can be driven to rotate clockwise and counterclockwise through the first connecting rod and the second connecting rod, which can further drive the drill rods clamped inside the positioning sleeve to flip, which is convenient and quick.

[0017] Please see Figures 1-2This utility model provides a technical solution: a rotating and highly stable upper rod mechanism, including a fixed frame 1, a positioning sleeve 11 rotatably connected to the inner side of the fixed frame 1, and a clamping block 15 movably connected to the inner side of the positioning sleeve 11, the number of clamping blocks 15 being three sets; a rotating mechanism: used to rotate the positioning sleeve 11, the rotating mechanism including a servo motor 14, a first connecting rod 12 and a second connecting rod 13 horizontally fixedly installed on both sides of the positioning sleeve 11 respectively, the first connecting rod 12 and the second connecting rod 13 on both sides of the positioning sleeve 11 being rotatably connected to both sides of the fixed frame 1 through bearings, the shaft end of the servo motor 14 being fixedly connected to the end of the first connecting rod 12 away from the positioning sleeve 11, the servo motor 14 being fixedly connected to the outer side of the fixed frame 1, the fixed frame 1 being U-shaped, and an installation groove 16 being provided through the middle of the bottom end of the fixed frame 1.

[0018] In this technical solution, the servo motor 14 is controlled by the corresponding controller, and the positioning sleeve 11 can be driven to rotate clockwise and counterclockwise inside the fixed frame 1 via the first connecting rod 12 and the second connecting rod 13, which further drives the drill rod clamped inside the positioning sleeve 11 to flip, which is convenient and quick.

[0019] In this embodiment, the adjustment mechanism is used to adjust the clamping block 15. The adjustment mechanism includes an air guide groove 22. Three sets of piston grooves 2 are evenly opened on the inner side of the positioning sleeve 11. A piston 21 is slidably connected to the inner side of the piston groove 2. One end of the clamping block 15 is placed inside the piston groove 2 and is fixedly connected to the middle of the piston 21. The air guide groove 22 is opened inside the positioning sleeve 11. The air guide groove 22 is annular and communicates with the three sets of piston grooves 2. An air inlet pipe 23 and an air outlet pipe 24 are horizontally fixedly installed inside the second connecting rod 13. The air outlet end of the air inlet pipe 23 and the air inlet end of the air outlet pipe 24 are both connected to the air guide groove 22. Solenoid valves 25 are provided inside the air inlet pipe 23 and the air outlet pipe 24.

[0020] In this technical solution, the air inlet end of the air inlet pipe 23 is connected to the air outlet of the corresponding air pump. The corresponding air pump is controlled to work and the solenoid valve 25 inside the air inlet pipe 23 is opened. Air can be introduced into the air guide groove 22 through the air inlet pipe 23, thereby introducing air into the three sets of piston grooves 2. The piston grooves 2 are movably connected to the piston 21. As the air pressure in the piston grooves 2 increases, the piston 21 can be pushed closer to the drill rod inside the positioning sleeve 11. This further pushes one end of the three sets of clamping blocks 15 to move out of the piston grooves 2 and press against the surface of the drill rod, thereby stably clamping the drill rods of different diameters inside the positioning sleeve 11.

[0021] In this embodiment, the clamping block 15 is movably connected to the piston groove 2, and the dimensions of the clamping block 15 and the piston groove 2 are matched.

[0022] In this technical solution, the air outlet end of the air outlet pipe 24 is connected to the air intake port of the air pump, the corresponding air pump is controlled to work, and the solenoid valve 25 inside the air outlet pipe 24 is opened. The air in the piston groove 2 can be extracted through the air outlet pipe 24. Under the action of external atmospheric pressure, the piston 21 can be pushed away from the drill rod in the middle of the positioning sleeve 11, thereby pulling the clamping block 15 into the piston groove 2, thereby releasing the clamping of the drill rod. It is convenient and quick. It should be noted that the servo motor 14 can drive the positioning sleeve 11 to rotate forward and reverse, and the air inlet pipe 23 and the air outlet pipe 24 will not get tangled.

[0023] When using a rotating and highly stable upper rod mechanism, the fixing frame 1 is fixed in a designated position by a corresponding fixing mechanism. One end of the drill rod is inserted into the middle of the positioning sleeve 11. Then, the air inlet end of the air inlet pipe 23 is connected to the air outlet of the corresponding air pump. The corresponding air pump is controlled to work and the solenoid valve 25 inside the air inlet pipe 23 is opened. Air can be injected into the air guide groove 22 through the air inlet pipe 23, thereby inflating the three sets of piston grooves 2. The piston grooves 2 are movably connected to the piston 21. As the air pressure in the piston grooves 2 increases, the piston 21 can be pushed closer to the drill rod inside the positioning sleeve 11, further pushing one end of the three sets of clamping blocks 15 out of the piston grooves 2 and pressing against the surface of the drill rod, thereby inflating the inside of the positioning sleeve 11. Drill rods of different diameters are stably clamped. The servo motor 14 is controlled by the corresponding controller to work. The first connecting rod 12 and the second connecting rod 13 can drive the positioning sleeve 11 to rotate clockwise and counterclockwise inside the fixed frame 1. This further drives the drill rod clamped inside the positioning sleeve 11 to flip, connecting the air outlet end of the air outlet pipe 24 to the air intake port of the corresponding air pump. This controls the operation of the corresponding air pump and opens the solenoid valve 25 inside the air outlet pipe 24. The air outlet pipe 24 can extract the air from the piston groove 2. Under the action of external atmospheric pressure, the piston 21 can be pushed away from the drill rod in the middle of the positioning sleeve 11, thereby pulling the clamping block 15 into the piston groove 2, further releasing the clamping of the drill rod, which is convenient and quick.
