Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, and more specifically, it relates to a drill pipe lifting and fixing frame. Background Technology

[0002] Drill pipe is a steel pipe with threads at the tail, used to connect the drilling rig's surface equipment to the drilling equipment or bottom hole assembly located at the bottom of the well. The purpose of drill pipe is to transport drilling mud to the drill bit and, together with the drill bit, raise, lower, or rotate the bottom hole assembly. Drill pipe must be able to withstand enormous internal and external pressure, torsion, bending, and vibration. In the process of oil and gas extraction and refining, drill pipe can be reused multiple times. Drill pipe is divided into three categories: angular drill pipe, drill rod, and heavy-duty drill pipe.

[0003] Based on the above, the inventors have discovered the following problems: When disassembling drill rods, it is necessary to lift the drill rods one section at a time and then disassemble them by rotation. The disassembled drill rods are usually stacked together or placed on a fixed frame. Placing them together may cause the upper drill rods to roll down, which is not stable and poses a certain danger. At this time, a fixed frame is needed to place the drill rods. However, the fixed frames currently used are not convenient for adjusting the length of the support. This results in insufficient support in the middle when the drill rods are stacked on the fixed frame, which may cause deformation in the middle of the drill rods and damage to the drill rods.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drill pipe lifting and fixing bracket in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a drill rod lifting and fixing bracket, which solves the problem that the current fixing bracket is inconvenient to adjust the length of the support, resulting in insufficient support in the middle when the drill rods are stacked on the fixing bracket, which may cause deformation in the middle of the drill rod.

[0006] The purpose and effect of this utility model's drill pipe lifting and fixing bracket are achieved by the following specific technical means:

[0007] A drill pipe lifting and fixing frame includes a frame, a rear transverse bar mounted on the frame, a support bar mounted on the inner side of the transverse bar, a support pillow movably connected to the support bar, two transverse bars, a rotating rod rotatably connected between the two transverse bars, a set of threads arranged in opposite directions at both ends of the rotating rod, two support pillows, the rotating rod being connected to the two support pillows respectively through a set of threads arranged in opposite directions, and a rotating handle mounted on one end of the rotating rod.

[0008] Furthermore, the surface of the support pillow is provided with multiple grooves, which are evenly distributed, and side baffles are provided at both ends of the support pillow.

[0009] Furthermore, the support pillow has through holes on both sides of the rotating rod, the cross-sectional size of the support rod is adapted to the size of the through holes, and the support rod passes through the interior of the through holes.

[0010] Furthermore, a fixed frame is installed in the middle of the upper part of the frame, a push cylinder is installed in the middle of the fixed frame, the output end of the push cylinder is connected to a lifting plate, and side fixing plates are arranged opposite each other on the inner side of the lifting plate.

[0011] Furthermore, a rotating rod is rotatably mounted in the middle of the lifting plate, and a set of bidirectional threads are provided on the rotating rod. The rotating rod is movably connected to the side fixing plate through the bidirectional threads.

[0012] Furthermore, two limiting rods are installed on both sides of the rotating rod on the lifting plate, and a side limiting block is installed on the inner side of the side fixing plate.

[0013] Furthermore, a dual-axis motor is connected to the middle of the rotating rod, the output end of the dual-axis motor is connected to the middle of the rotating rod, and the dual-axis motor is connected to the lifting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, a rotating handle drives a rotating rod to rotate. When the rotating rod rotates, it drives the thread to rotate synchronously. The rotating rod drives the support pillow to move horizontally through the thread. At this time, the two support pillows can move inward or outward simultaneously. Adjusting the distance between the two support pillows allows the support pillows to support drill rods of different lengths. At the same time, the support rods on both sides can provide support force for the support pillows and drill rods, ensuring that the movement of the support pillows is more stable.

[0016] In this invention, the output end of the cylinder pushes the lifting plate downward. When the lifting plate moves the side fixing plate to the side of the drill rod, the dual-axis motor is started. The dual-axis motor can drive the rotating rod to rotate. When the rotating rod rotates, the two side fixing plates can move inward synchronously through the bidirectional thread. The two side fixing plates drive the side limit block to contact the side of the drill rod, restricting the sides of the drill rods stacked together, preventing the drill rods from rolling off, and improving the overall stability.

[0028] This utility model provides a drill pipe lifting and fixing frame, including a frame 1, a rear transverse rod 2 installed on the frame 1, a support rod 3 installed on the inner side of the transverse rod 2, and a support pillow 4 movably connected to the support rod 3. There are two transverse rods 2, and a rotating rod 7 is rotatably connected between the two transverse rods 2. Both ends of the rotating rod 7 have a set of threads 8 arranged in opposite directions. There are two support pillows 4, and the rotating rod 7 is connected to the two support pillows 4 respectively through a set of threads 8 arranged in opposite directions. A rotating handle 9 is installed at one end of the rotating rod 7. Multiple grooves 5 are evenly distributed on the surface of the support pillow 4, and side grooves are provided at both ends of the support pillow 4. The baffle 6 and the support pillow 4 have through holes on both sides of the rotating rod 7. The cross-sectional size of the support rod 3 is matched with the size of the through hole. The support rod 3 passes through the inside of the through hole. The rotating rod 7 is driven to rotate by rotating the handle 9. When the rotating rod 7 rotates, it can drive the thread 8 to rotate synchronously. The rotating rod 7 drives the support pillow 4 to move horizontally through the thread 8. At this time, the two support pillows 4 can move inward or outward simultaneously. Adjusting the distance between the two support pillows 4 can allow the support pillows 4 to support drill rods of different lengths. At the same time, the support rods 3 on both sides can provide support force for the support pillows 4 and the drill rod, ensuring that the movement of the support pillows 4 is more stable.

[0029] The frame 1 has a fixed frame 10 installed in the middle of its upper part. A push cylinder 11 is installed in the middle of the fixed frame 10. The output end of the push cylinder 11 is connected to a lifting plate 12. Side fixing plates 16 are arranged opposite each other on the inner side of the lifting plate 12. A rotating rod 13 is rotatably installed in the middle of the lifting plate 12. A set of bidirectional threads 14 are opened on the rotating rod 13. The rotating rod 13 is movably connected to the side fixing plates 16 through the bidirectional threads 14. Two limiting rods 15 are installed on the lifting plate 12 on both sides of the rotating rod 13. The limiting rods 15 are located on both sides of the rotating rod 13. Side limiting blocks 17 are installed on the inner side of the side fixing plates 16. The part is connected to a dual-axis motor 18. The output end of the dual-axis motor 18 is connected to the middle of the rotating rod 13. The dual-axis motor 18 is connected to the lifting plate 12. By pushing the output end of the cylinder 11, the lifting plate 12 is pushed to move downward. When the lifting plate 12 moves the side fixing plate 16 to the side of the drill rod, the dual-axis motor 18 is started. The dual-axis motor 18 can drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it can drive the two side fixing plates 16 to move inward synchronously through the bidirectional thread 14. The two side fixing plates 16 drive the side limit block 17 to contact the side of the drill rod, restricting the side of the drill rod stacked together and preventing the drill rod from rolling off.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this invention, firstly, the rotating handle 9 is rotated, which drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, it drives the threaded rod 8 to rotate synchronously. The rotating rod 7 drives the support pillow 4 to move horizontally through the threaded rod 8. At this time, the two support pillows 4 can move inward or outward synchronously. Adjusting the distance between the two support pillows 4 allows the support pillows 4 to support drill rods of different lengths. At the same time, the support rods 3 on both sides can provide support force for the support pillows 4 and the drill rod, ensuring that the support pillows 4 move more smoothly. After the drill rod is placed, the push cylinder 11 is started. The output end of the push cylinder 11 pushes the lifting plate 12 to move downward. When the lifting plate 12 drives the side fixing plate 16 to move to the side of the drill rod, the dual-axis motor 18 is started. The dual-axis motor 18 can drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it drives the two side fixing plates 16 to move inward synchronously through the bidirectional threaded rod 14. The two side fixing plates 16 drive the side limit block 17 to contact the side of the drill rod, restricting the side of the stacked drill rods and preventing the drill rods from rolling off.
