Description

Technical Field

[0001] The present invention is applicable to the field of oil drilling, and particularly relates to an automatically controlled integrated traveling block and hook. Background Art

[0002] In drilling operations, drilling tools such as drill pipes and drill bits need to be lowered into the well, and power for lifting and lowering them is provided during drilling. The traveling block and hook is a crucial device in the drilling hoisting system, undertaking important tasks such as running and pulling out drill tools, bearing the weight of the drill string, and handling complex downhole conditions.

[0003] The traveling block and hook can be divided into two types: integrated type and split type. The split-type traveling block and hook has some deficiencies. Its overall size is relatively large, and the structure lacks compactness. When the sliding traveling block and the hook interact, the impact force generated between them is relatively strong, resulting in poor applicability. The integrated traveling block and hook, on the other hand, connects the sliding traveling block and the hook through two load-bearing pin shafts. This connection method reduces the overall size and makes the structure more compact, enabling full utilization of the derrick space, thus having stronger applicability. The traditional braking device of the traveling block and hook mainly uses a cam plus lock ring groove structure. The wellhead operator rotates the handle to open the cam, and then pushes the hook to rotate to a certain position and releases the handle. The cam then catches into the lock ring groove to lock the hook. The traditional mechanical structure has many drawbacks, which bring great inconvenience to manual operation. Moreover, problems such as failure to lock tightly and jamming will occur as the usage time increases. To effectively solve these problems, the automatically controlled integrated traveling block and hook came into being.

[0004] In recent years, with the continuous development of the oil industry, automatic control technology has been widely applied. This technology can remotely control the rotation positioning and hook body opening and closing of the traveling block and hook, reducing manual operation. At the same time, it can adapt to complex working environments, further improving the efficiency and safety of drilling operations. Summary of the Invention

[0005] The purpose of the present invention is to propose an automatically controlled integrated traveling block and hook to solve the problems in the above background, and combined with automatic control, effectively improve the working stability and efficiency of the traveling block and hook.

[0006] To solve the above problems, the technical solution adopted by the present invention is that the automatically controlled integrated traveling block and hook includes a sliding traveling block part and a hook part, and is connected together through two load-bearing pin shafts.

[0007] The sliding traveling block part includes an upper crossbeam and a shroud assembly, an upper crossbeam pin shaft, a moving pulley block, a double-row tapered roller bearing, a pulley shaft, and a side plate. The upper crossbeam and the shroud assembly are connected to the side plate through the upper crossbeam pin shaft. The double-row tapered roller bearing has a high load-bearing capacity and can adapt to various load conditions. There are five of them in total and they are evenly arranged on the pulley shaft. This arrangement reduces the friction between the pulley shaft and the inner ring of the bearing, improves efficiency, and at the same time enables the rational arrangement of the parts on the shaft, enhancing the strength of the shaft. The moving pulley block has five pulleys, which are arranged one by one on the double-row tapered roller bearings, and their fit is an interference fit. The upper crossbeam and the shroud assembly are provided with a rope retaining mechanism to prevent the wire rope from jumping off and causing damage when moving around the pulley, and at the same time, the rope threading will be more convenient. Oil grooves and oil holes are opened on the pulley shaft for lubricating the bearing to ensure the service life of the double-row tapered roller bearing. The sliding traveling block part has a streamlined shape to prevent the sliding traveling block from accidentally touching other well tools during the up-and-down reciprocating motion.

[0008] The big hook part includes a cylinder upper cover, an upper spring seat, a hook rod, a spring, a cylinder body, a lower spring seat, a positioning bushing, an L-shaped bearing seat, a large bevel gear, a small bevel gear, an upper motor, a worm wheel spline sleeve, a worm, a battery pack, a control unit, a thrust cylindrical roller bearing, a hook body sleeve, a hook rod pin shaft, a gear crank, a lower motor, a straight crank, and a hook body. The cylinder upper cover is installed on the upper part of the cylinder body by bolt connection to prevent foreign objects from entering the interior of the cylinder body. There are two upper spring seats in total, and the two upper spring seats and the hook rod are fitted together by bolt connection. Both ends of the spring are arranged on the upper and lower spring seats. When the big hook is loaded, the hook rod drives the upper spring seat to move downward, and at this time the spring is compressed to achieve the purpose of shock absorption and buffering. The cylinder body and the side plate are connected by two load-bearing pin shafts, making the sliding block and the big hook an integral whole. The lower spring seat is placed on the positioning bushing and has an interference fit with the hook rod. The hook rod and the worm wheel spline sleeve are connected through internal and external splines to transmit torque. The outside of the worm wheel spline sleeve is a worm wheel tooth structure, which meshes with the worm to complete the transmission. The large bevel gear is connected to one end of the worm by thread, and the small bevel gear is connected to the upper motor by a key to achieve the purpose of torque transmission. The hook rod, the large bevel gear, the small bevel gear, the upper motor, the worm wheel spline sleeve, the worm, the battery pack, and the control unit form an automatic positioning device. The control unit includes an IMU, an MCU, a motor driver, a filter circuit, and a DC-DC buck converter, and is integrated on a PCB. The motors are all selected as DC motors. The DC-DC buck converter converts the input DC high voltage into DC low voltage. The IMU transmits the current angular velocity information to the MCU. After being processed by the MCU, the current angle signal is transmitted to the terminal device by wireless transmission. The operator inputs the specific angle according to the information received by the terminal device to control the rotation of the upper motor, and the rotation speed is transmitted to the hook rod after speed reduction to make it rotate smoothly, so as to achieve the purpose of changing the opening direction of the hook body. The battery pack is placed in the cylinder seat and is connected to the control unit by a wire to supply power to the control unit. The control unit is connected to the upper motor and the lower motor by wires to transmit signals. The thrust cylindrical roller bearing has a clearance fit with the hook rod and is arranged at the lower part of the cylinder body to bear the impact when the hook rod descends under load. The hook body sleeve, the gear crank, the lower motor, the straight crank, and the hook body form a hook body module. The hook body sleeve is connected to the hook rod by a hook rod pin shaft. The hook body is connected to the hook body sleeve by a gear crank and a straight crank. The lower motor is connected to the gear crank by a key to transmit torque. When the upper motor rotates the opening direction of the hook body to the desired angle, the operator controls the terminal device to start the lower motor, and the forward and reverse rotation of the lower motor drives the gear parts of the left and right gear cranks to mesh to control the opening and closing of the hook body.

[0009] The movable pulley block of the sliding block of the integrated automatic control traveling block is connected to the crown block by a wire rope and makes reciprocating up and down movements; before bearing the hook load, the opening orientation angle of the hook body is rotated to the desired angle through the automatic positioning device, and then the lower motor is driven to rotate to control the opening and closing of the hook body, and tools such as sling rings are hooked or lowered; when the traveling block is subjected to a relatively small load, the spring is stressed, and the thrust is transmitted unidirectionally, and the thrust cylindrical roller bearing does not bear force. As the hook load gradually increases, the spring gradually bears pressure and deforms. The reaction force and balance force generated also increase with the deformation of the spring. At this time, the thrust cylindrical roller bearing still does not bear force. Only when the hook load increases to a certain value, the spring deformation reaches the maximum value of the installation space and conditions, and the resistance force generated by the spring reaches the maximum value, the bottom of the external spline of the hook rod contacts the thrust cylindrical roller bearing. At this time, the bearing is in a state of just about to bear force but still not bearing force. When the hook load continues to increase, the increased hook load is borne by the thrust cylindrical roller bearing. This method of bearing the hook load is very reasonable, which not only achieves the role of buffering and shock absorption, but also allows the hook load to be jointly borne by the spring and the thrust cylindrical roller bearing, improving the service life of each part.

[0010] As a further technical solution of the present invention, the automatic positioning device can transmit the speed of the upper motor to the hook rod after deceleration, so that the movement of the hook rod is stable to ensure the opening orientation angle of the hook body. At the same time, the meshing mode of the worm and the worm wheel spline sleeve is the meshing of the worm and worm wheel with a large transmission ratio, which can realize the self-locking function to achieve the positioning function.

[0011] As a further technical solution of the present invention, in the hook body module, the forward and reverse rotation of the lower motor is controlled by the terminal device to drive the meshing of the gears of the left and right gear cranks to control the opening and closing of the hook body. Cooperating with the crown block, it can realize high-precision remote operation of hanging sling rings and swivels, with stronger force control, replacing manual operation.

[0012] As a further technical solution of the present invention, the automatic positioning device and the hook body module achieve remote control through wireless communication technology, without complex cable layout, making the operation of the equipment more convenient. Drilling workers can remotely monitor and adjust the rotation angle of the traveling block and the opening and closing of the hook body through a mobile terminal device with wireless communication technology.

[0013] As a further technical solution of the present invention, the force-bearing components such as the pulley shaft, side plate, bearing pin, cylinder body, hook rod, hook rod pin, and hook body module are all forged from low-carbon high-quality alloy steel to ensure the strength requirements of the traveling block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention connects the sliding block and the traveling block through two bearing pins, reducing the overall size, making the structure more compact, being able to make full use of the derrick space, and having stronger applicability.

[0016] 2. The present invention adopts an automatic control technology, which can remotely and precisely control the rotation and positioning of the hook head and the opening and closing of the hook body in real time, replacing manual operation, making the operation process safer and improving the efficiency of drilling operations at the same time.

This arrangement reduces the friction between the pulley shaft 5 and the inner ring of the bearing, improves efficiency, and at the same time enables the rational arrangement of the parts on the shaft, enhancing the strength of the shaft. The moving pulley block 3 has five pulleys and is arranged one by one on the double-row tapered roller bearing 4, and their fit is an interference fit. The upper crossbeam and the guard assembly 1 are provided with a rope retaining mechanism to prevent the wire rope from jumping off when moving around the pulley, causing damage, and at the same time making the threading more convenient.

The cylinder upper cover 8 is installed on the upper part of the cylinder 12 by bolt connection to prevent foreign objects from entering the inside of the cylinder 12. There are two upper spring seats 9 in total, and the two upper spring seats 9 and the hook rod 10 are fitted together by bolt connection. The two ends of the spring 11 are arranged on the upper and lower spring seats. When the hook is loaded, the hook rod 10 drives the upper spring seat 9 to move downward, and at this time the spring 11 is compressed to achieve the purpose of shock absorption and buffering. The cylinder 12 and the side plate 6 are connected by two load-bearing pin shafts 7, making the traveling block and the hook an integral whole. The lower spring seat 13 is placed on the positioning bushing 14 and has an interference fit with the hook rod 10. The hook rod 10 and the worm wheel spline sleeve 19 are connected by internal and external splines to transmit torque. The outside of the worm wheel spline sleeve 19 is a worm wheel tooth structure 1901, which meshes with the worm 20 to complete the transmission. The large bevel gear 16 is connected to one end of the worm 20 by thread, and the small bevel gear 17 is connected to the upper motor 18 by a key to achieve the purpose of torque transmission. The hook rod 10, the large bevel gear 16, the small bevel gear 17, the upper motor 18, the worm wheel spline sleeve 19, the worm 20, the battery pack 21, and the control unit 22 form an automatic positioning device. The control unit 22 includes an IMU, an MCU, a motor driver, a filter circuit, and a DC-DC buck converter, and is integrated on a PCB. All motors are selected as DC motors. The DC-DC buck converter converts the input DC high voltage into DC low voltage. The IMU transmits the current angular velocity information to the MCU. After being processed by the MCU, the current angle signal is transmitted to the terminal device through a wireless transmission method. The operator inputs the specific angle according to the information received by the terminal device to control the rotation of the upper motor 18, and the rotation speed is transmitted to the hook rod 10 after speed reduction to make it rotate smoothly, so as to achieve the purpose of changing the opening direction of the hook body. At the same time, the meshing mode of the worm 20 and the worm wheel spline sleeve 19 is a worm and worm wheel meshing with a large transmission ratio, which can realize the self-locking function to achieve the positioning function. The battery pack 21 is placed in the cabin seat of the cylinder 12 and is connected to the control unit 22 by a wire to supply power to the control unit 22. The control unit 22 is connected to the upper motor 18 and the lower motor 27 by wires to transmit signals. The thrust cylindrical roller bearing 23 and the hook rod 10 are arranged in the lower part of the cylinder 12 with a clearance fit to bear the impact when the hook rod 10 descends under load. The hook body sleeve 24, the gear crank 26, the lower motor 27, the straight crank 28, and the hook body 29 form a hook body module. The hook body sleeve 24 is connected to the hook rod 10 by the hook rod pin shaft 25, and the hook body 29 is connected to the hook body sleeve 24 by the gear crank 26 and the straight crank 28. The lower motor 27 is connected to the gear crank 26 by a key to transmit torque. When the upper motor 18 rotates the opening direction of the hook body to the desired angle,The operator controls the lower motor 27 of the terminal device to start, and drives the gear of the left and right gear cranks 26 to rotate forward and backward to control the opening and closing of the hook body 29 through meshing.

[0029] In this embodiment, the movable pulley block 3 of the traveling block part is connected to the crown block by a wire rope and makes a reciprocating up and down movement; before bearing the hook load, the opening orientation angle of the hook body 29 is rotated to the desired angle through the automatic positioning device, and then the lower motor 27 is driven to rotate to control the opening and closing of the hook body 29, and tools such as sling rings are hooked or lowered; when the traveling block hook is subjected to a relatively small load, the spring 11 is stressed, and the thrust is transmitted unidirectionally, and the thrust cylindrical roller bearing 23 is not stressed. As the hook load gradually increases, the spring 11 gradually bears pressure and deforms. The reaction force and the balance force generated also increase with the deformation of the spring 11. At this time, the thrust cylindrical roller bearing 23 is still not stressed. Only when the hook load increases to a certain value and the deformation of the spring 11 reaches the maximum value of the installation space and conditions, and the reaction force generated by the spring 11 reaches the maximum value, the bottom of the external spline 1001 of the hook rod contacts the thrust cylindrical roller bearing 23. At this time, the thrust cylindrical roller bearing 23 is in a state of just about to be stressed but still not stressed. When the hook load continues to increase, the increased hook load is borne by the thrust cylindrical roller bearing 23.

[0030] In a specific embodiment, during the operation of the automatic control integrated traveling block hook, the movable pulley block 3 of the traveling block part is connected to the crown block by a wire rope and makes a reciprocating up and down movement. When it is necessary to lift the drill string, the drawworks lowers the traveling block hook through the wire rope. The control unit 22 detects whether the current angle is the desired angle. The angle that the hook can rotate on the horizontal plane is 0° to 180°. After driving the upper motor 18 to rotate the hook to the desired angle, the operator drives the lower motor 27 to rotate through the terminal mobile device to control the opening and closing of the hook body 29. The angles at which the gear crank 26 and the straight crank 28 can open or contract are 34° to 110°. 34° is the state when the hook body 29 is completely closed, and 110° is the state when the hook body 29 is completely opened. After connecting the top joint of the drill string, the drawworks lifts the traveling block hook through the wire rope. As the traveling block hook rises, the drill string is gradually lifted out of the wellbore.

[0031] The above embodiments are only a part of the present invention, not all of it. Based on these embodiments, other embodiments obtained by those of ordinary skill in the art without creative work are also within the protection scope of the present invention.
