Description

Technical Field

[0001] The utility model belongs to the technical field of oil drilling equipment, and particularly relates to a disassembly and assembly workbench for oil drilling equipment. Background Art

[0002] Oil drilling equipment is a complex mechanical equipment system used for drilling oil and natural gas underground. It mainly consists of key components such as a drilling rig, a derrick, a mud pump, a drill bit, a rotary table, and a power system. The drill bit is a component used to break or cut the formation, and there are various types, including basic drill bits, reamers, drill bit tongs, etc. The drill bit breaks or cuts the underground rock formation through rotation and thrust, making the drill hole continuously extend downward.

[0003] In oil drilling operations, the disassembly and assembly of drill bits is a frequent and important link. Most of the existing drill bit disassembly and assembly workbenches clamp the drill bits through a clamping mechanism. Also, because the drill bits are irregular in shape, the clamping of the drill bits is not very stable, and they are prone to looseness during disassembly and assembly, affecting the disassembly and assembly efficiency, increasing the labor intensity, and posing challenges to the safety and continuity of the operation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a disassembly and assembly workbench for oil drilling equipment, which can stably fix the drill bit, avoid the disadvantages of unstable fixation using a clamping mechanism, improve the efficiency and safety of disassembly and assembly operations, effectively reduce the labor intensity of operators, and provide strong support for the smooth progress of oil drilling operations.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] A disassembly and assembly workbench for oil drilling equipment includes a workbench. Two first mounting ears are fixed on the top of the workbench. A double-headed lead screw is rotatably installed between the outer walls of the two first mounting ears. A square cover is fixed on the top of the workbench. A first bevel gear is fixed on the outer wall of the double-headed lead screw inside the square cover. Second lead screws are rotatably installed through both sides of the square cover and on both sides of the double-headed lead screw. A second bevel gear meshing with the first bevel gear is fixed at one end of each second lead screw. Moving blocks are threadedly connected to the outer walls of the second lead screws and the double-headed lead screw on one side of the square cover. An arc-shaped plate is fixed on the top of each moving block. A support plate is fixed on the top of the square cover. A motor is arranged on the top of the workbench, and one end of the output shaft of the motor is connected to one end of the double-headed lead screw.

[0007] Further, two moving blocks are threadedly connected to the outer wall of the double-headed lead screw. There are four moving blocks, and the included angle between two adjacent moving blocks is ninety degrees.

[0008] Furthermore, the four arc-shaped plates are arranged in a circumferential direction, and internal threads are provided between the inner sides of the four arc-shaped plates.

[0009] Furthermore, tool boxes are provided on both sides of the square cover at the top of the workbench.

[0010] Furthermore, tool cabinets are provided on both sides of the bottom of the workbench, and support feet are fixed at the four corners of the bottom of the tool cabinets.

[0011] Furthermore, a distance measuring sensor is provided on one side of the square cover, a display screen is provided on the top of the workbench on the side of the tool box, two control buttons are fixed on one side of the workbench, the distance measuring sensor is electrically connected to the display screen, and the control buttons are electrically connected to the motor.

[0012] The technical effects achieved by the present utility model are as follows:

[0013] For the disassembly and assembly workbench for oil drilling equipment of the present utility model, the motor drives the double-headed lead screw to rotate, and cooperates with the first bevel gear and the second bevel gear to drive the second lead screw to rotate. The rotation of the double-headed lead screw and the second lead screw drives the corresponding moving blocks to move. With the precise displacement of the moving blocks, the arc-shaped plates connected to their tops and the internal thread structure also adjust their positions accordingly. The multiple arc-shaped plates gradually converge during the dynamic adjustment, and they jointly enclose a circular space that perfectly matches the thread diameter of the drill bit connection. This intelligent adjustment method ensures that no matter how complex and variable the shape of the drill bit is, precise and stable adaptation can be achieved. After adjustment, the drill bit is screwed into the space between the multiple arc-shaped plates, thereby stably fixing the drill bit, avoiding the drawback of unstable fixation using a clamping mechanism, improving the efficiency and safety of the disassembly and assembly operation, effectively reducing the labor intensity of the operator, and providing strong support for the smooth progress of oil drilling operations.

[0020] As Figures 1-3 shown, a disassembly and assembly workbench for oil drilling equipment includes a workbench 1. Two first mounting ears are fixed on the top of the workbench 1. A double-headed lead screw 2 is rotatably installed between the outer walls of the two first mounting ears. A square cover 9 is fixed on the top of the workbench 1. A first bevel gear 3 is fixed on the outer wall of the double-headed lead screw 2 inside the square cover 9. Second lead screws 4 are rotatably installed through both sides of the square cover 9 and on both sides of the double-headed lead screw 2. Second mounting ears rotatably connected to the second lead screws 4 are fixed on the top of the workbench 1. A second bevel gear 5 meshing with the first bevel gear 3 is fixed at one end of the second lead screw 4. Moving blocks 6 are screwed on the outer walls of the second lead screw 4 and the double-headed lead screw 2 on one side of the square cover 9. Two moving blocks 6 are screwed on the outer wall of the double-headed lead screw 2. The number of moving blocks 6 is four, and the included angle between two adjacent moving blocks 6 is ninety degrees. The rotating double-headed lead screw 2 can drive the first bevel gear 3 to rotate. The first bevel gear 3 meshes with the second bevel gear 5, which can drive the second lead screw 4 to rotate, so that the four moving blocks 6 can move synchronously, adjusting the distance between the moving blocks 6 to facilitate fixing drill bits of different sizes. Guide rods slidably connected to the moving blocks 6 are fixed on the peripheral side walls of the square cover 9, making the movement of the moving blocks 6 more stable. Arc plates 7 are fixed on the tops of the moving blocks 6. The four arc plates 7 are arranged along the circumferential direction. An internal thread 8 is provided between the inner sides of the four arc plates 7. A support plate 10 is fixed on the top of the square cover 9. A motor 11 is arranged on the top of the workbench 1. One end of the output shaft of the motor 11 is connected to one end of the double-headed lead screw 2;

[0021] Start the motor 11. The motor 11 drives the double-headed lead screw 2 to rotate. The double-headed lead screw 2 drives the second lead screw 4 to rotate through the meshing of the first bevel gear 3 and the second bevel gear 5. The rotation of the double-headed lead screw 2 and the second lead screw 4 drives the moving blocks 6 to move synchronously. The moving blocks 6 drive the arc plates 7 to move. Adjust according to the diameter of the connection thread on the drill bit. After adjustment, screw the drill bit onto the internal thread 8 between the multiple arc plates 7, thus completing the fixation of the drill bit and facilitating the subsequent disassembly and assembly of the drill bit;

[0022] As Figures 1-2 shown, tool boxes 15 are provided on the top of the workbench 1 and on both sides of the square cover 9. Tool cabinets 16 are provided on both sides of the bottom of the workbench 1. Support feet are fixed at the four corners of the bottom of the tool cabinet 16.

A display screen 13 is provided on the top of the workbench 1 and on one side of the tool box 15, which is convenient for displaying the distance between the square cover 9 and the moving block 6 detected by the distance measuring sensor 12, so that the personnel can intuitively know the distance between the square cover 9 and the moving block 6. Two control buttons 14 are fixed on one side of the workbench 1. The distance measuring sensor 12 is electrically connected to the display screen 13, and the control buttons 14 are electrically connected to the motor 11. The forward and reverse rotation of the motor 11 is controlled through the control buttons 14, so as to adjust the movement of the moving block 6, which is relatively perfect and practical.

[0024] The working principle of the present utility model is as follows: When in use, according to the diameter of the connection thread on the drill bit, the motor 11 is started by controlling the control buttons 14. The motor 11 drives the double-headed lead screw 2 to rotate. The double-headed lead screw 2 drives the second lead screw 4 to rotate through the meshing of the first bevel gear 3 and the second bevel gear 5. The rotation of the double-headed lead screw 2 and the second lead screw 4 drives the moving block 6 to move synchronously. The moving block 6 drives the arc plate 7 to move, and the arc plate 7 drives the internal thread 8 to move. It is adjusted according to the diameter of the connection thread on the drill bit. With the cooperation of the distance measuring sensor 12 and the display screen 13, the arc plate 7 moves precisely. After adjustment, the connection thread on the drill bit is screwed between multiple arc plates 7, so as to fix the drill bit, which is convenient for subsequent disassembly and assembly.

[0025] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
