Description

Technical Field

[0001] The present invention relates to the technical field of oil wells, and more particularly to a mechanical arm for pressure-operated operations at a well site. Background Art

[0002] Wellsite pressure operation refers to an advanced downhole operation technology that is used to pull in and out the pipe string and implement production-increasing measures while maintaining a certain pressure in the wellbore, without compressing (washing) the well or releasing the pressure. In wellsite pressure operation, the robotic arm plays a vital role. It can accurately complete various operation tasks in a high-pressure environment according to the operation requirements, such as handling and positioning of the drill string, maintenance and repair of equipment, etc. At the same time, the robotic arm is also equipped with high-precision sensors and feedback mechanisms, which can monitor the operation status in real time and adjust the control strategy to ensure the safety and stability of the operation.

[0003] The well site pressure operation manipulator plays a vital role in well site operations. The manipulator can accurately grab the oil pipes and sucker rods stored on the ground or at the wellhead through its high degree of freedom structure, such as rotation, extension, lifting and other actions. The grabbed oil pipes and sucker rods can be safely and efficiently delivered to the wellhead or sent back from the wellhead to the designated storage location on the ground through the conveying function of the manipulator. In this process, the manipulator must ensure that the oil pipes and sucker rods are not damaged, and avoid safety hazards such as knocking and hitting the operators.

[0004] In the existing technical solutions, multiple safety measures should be installed on the robotic arm, such as anti-clamping devices, emergency stop buttons, safety fences, etc., to prevent failures or accidents during operation. However, when the robotic arm tilts or falls over, general safety measures cannot effectively reduce the damage after the robotic arm falls over. The tilting or falling of the robotic arm will cause damage to itself or other equipment connected to it. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a mechanical arm for well site pressure operation, which can achieve the effect of auxiliary protection for the mechanical arm that is about to tilt. The design of the stabilizing support rod increases the overall structural stability of the mechanical arm. When the arm is overloaded or subjected to other external forces, the stabilizing support rod can effectively resist the tendency of tilting or tipping and maintain the smooth operation of the mechanical arm. By adding the stabilizing support rod, the carrying capacity of the mechanical arm is improved.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A mechanical arm for well site pressure operation, comprising a mechanical frame, wherein a position adjustment component is commonly provided inside and outside the mechanical frame, the position adjustment component comprises a limiting groove opened inside the left and right sides of the mechanical frame, a nut seat is slidably installed inside the limiting groove, a driving seat is fixedly connected between adjacent nut seats, a driving seat and an upper end of the nut seat are both provided with a driving locking component, the driving locking component comprises a driving electric cylinder fixedly installed on the driving seat and the upper end surface of the nut seat, a bearing support plate is fixedly installed on the upper end surface of the driving electric cylinder, and locking slide bars fixed on the driving seat and the upper end surface of the nut seat are provided on the left and right sides of the driving electric cylinder, and the locking slide bars are slidably connected to the bearing support plate.

[0008] Furthermore, the position adjustment component also includes a drive motor fixedly mounted on the front end of the mechanical frame, and a ball screw is fixedly mounted on the output end of the drive motor.

[0009] Furthermore, a robot drive assembly is arranged at the middle position of the upper end surface of the driving seat, and the robot drive assembly includes a robot base fixedly installed at the middle position of the upper end surface of the driving seat, and a servo motor is fixedly installed at the middle position of the robot base.

[0010] Furthermore, a driving gear is fixedly installed on the output end of the servo motor, a connecting seat is rotatably installed on the upper end surface of the robotic arm base, a driven gear ring partially meshing with the driving gear is fixedly installed on the inner lower end of the connecting seat, and an arm rod is fixedly installed on the upper end surface of the connecting seat.

[0011] Furthermore, a stabilizing component is provided at the connection between the connecting seat and the robot arm base, and the stabilizing component includes a stabilizing groove opened on the upper end surface of the connecting seat, a ball is arranged inside the stabilizing groove, a sliding ring is slidably connected to the upper side of the inner part of the stabilizing groove, and the upper end surface of the sliding ring is fixedly connected to the connecting seat.

[0012] Furthermore, a limiting slide groove is provided at the upper end of the connection seat, a limiting wheel is slidably installed inside the limiting slide groove, a stabilizing support rod is rotatably installed at the middle position of the limiting wheel, and the top end of the stabilizing support rod is fixedly connected to the connection seat.

[0013] Furthermore, a connecting groove is fixedly connected between the limiting slide groove and the stabilizing slide groove, and the number of the connecting grooves is multiple. A one-way liquid inlet valve tube passes through the outer wall of the stabilizing slide groove, and a one-way liquid discharge valve tube passes through the bottom end of the limiting slide groove.

[0014] Furthermore, an oil tank is provided inside the locking slide rod, a main pipe runs through the bottom side wall of the oil tank, and one end of the main pipe away from the oil tank is interconnected with a one-way liquid inlet valve pipe and a one-way liquid discharge valve pipe.

[0015] Furthermore, a locking support rod is slidably installed inside the upper end of the locking slide rod, and a spring is fixedly connected between the locking support rods.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The stabilizing support rod provided in this solution can have a pulling effect on the connecting seat in a tilted state, so as to provide auxiliary protection for the mechanical arm that is about to tilt. The design of the stabilizing support rod increases the overall structural stability of the mechanical arm. When the arm is overloaded or under the action of other external forces, the stabilizing support rod can effectively resist the tendency of tilting or tipping, and maintain the stable operation of the mechanical arm. By adding the stabilizing support rod, the carrying capacity of the mechanical arm is improved. Most importantly, this design significantly improves the safety of the mechanical arm. When the arm is overloaded or under other abnormal conditions, the stabilizing support rod can quickly play a role to prevent the mechanical arm from tilting or tipping, thereby avoiding possible accidents and injuries. This solution supports the load-bearing pallet by locking the support rod, so that the load-bearing pallet can better support the tipping robot arm. Such a setting can cooperate with the stabilizing component to further effectively resist the tendency of tilting or tipping, which helps to protect other equipment and structures and avoid chain reactions or further damage caused by the tipping of the robot arm. This design not only improves the stability of the robot arm when it tips over, but also enhances the stability of the entire system. The synergistic effect of the locking slide rod and the driving electric cylinder enables the robot arm to maintain a relatively stable posture even in abnormal situations, reducing the safety hazards caused by tipping. In this solution, when there is more oil in the stabilizing slide, the connecting groove and the limiting slide, the oil can flow back to the oil tank through the one-way drain valve pipe and the main pipe, thereby realizing the circulation of the oil. The circulating oil can provide sufficient lubrication, and sufficient lubrication can ensure that the various components of the robotic arm are closely matched and move smoothly during operation; this helps to reduce looseness or sticking caused by friction and wear, and improve the overall stability of the robotic arm.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 , Figures 6 to 9A mechanical arm for well site pressure operation, comprising a mechanical frame 1, wherein a position adjustment component 2 is commonly provided inside and outside the mechanical frame 1, wherein the position adjustment component 2 comprises a limiting groove 204 provided inside the left and right sides of the mechanical frame 1, wherein a nut seat 205 is slidably installed inside the limiting groove 204, wherein a driving seat 203 is fixedly connected between adjacent nut seats 205, wherein the upper ends of the driving seat 203 and the nut seat 205 are both provided with a driving locking component 3, wherein the driving locking component 3 comprises a driving electric cylinder 301 fixedly installed on the upper end surfaces of the driving seat 203 and the nut seat 205, wherein a bearing support plate 302 is fixedly installed on the upper end surface of the driving electric cylinder 301, wherein locking slide bars 303 fixed on the upper end surfaces of the driving seat 203 and the nut seat 205 are provided on the left and right sides of the driving electric cylinder 301, wherein the locking slide bars 303 and the bearing support plate 302 are fixedly installed on the upper end surfaces of the driving seat 203 and the nut seat 205 ... The plates 302 are slidingly connected, and the position adjustment component 2 also includes a driving motor 201 fixedly installed at the front end of the mechanical frame 1, and a ball screw 202 is fixedly installed at the output end of the driving motor 201. A mechanical arm driving component 4 is arranged at the middle position of the upper end surface of the driving seat 203. The mechanical arm driving component 4 includes a mechanical arm base 401 fixedly installed at the middle position of the upper end surface of the driving seat 203, a servo motor 402 is fixedly installed at the middle position of the mechanical arm base 401, and a driving gear 403 is fixedly installed at the output end of the servo motor 402. A connecting seat 405 is rotatably installed on the upper end surface of the mechanical arm base 401, and a driven gear ring 404 partially meshing with the driving gear 403 is fixedly installed at the inner lower end of the connecting seat 405, and an arm rod 5 is fixedly installed on the upper end surface of the connecting seat 405.

[0021] By adopting the above technical solution, when in use, the mechanical frame 1 is placed at a suitable position in the well site. When the position of the mechanical arm needs to be adjusted, the drive motor 201 is started. The drive motor 201 can drive the ball screw 202 to rotate. The intermediate bodies such as balls are continuously filled between the ball screw 202 and the nut seat 205 to reduce friction and improve transmission efficiency. The balls circulate and roll in the spiral grooves of the ball screw 202 and the nut seat 205 to ensure the smooth linear motion of the nut. The linear motion of the nut seat 205 can drive the drive seat 203 to move in the limit groove 204 together, so that the mechanical arm on the drive seat 203 can be driven to drive. The component 4 moves together, and the movement of the robot arm driving component 4 can drive the position of the arm 5 to move, so as to adjust the position of the entire robot arm. When the robot arm is needed to work, the servo motor 402 is started, and the servo motor 402 can drive the driving gear 403 to rotate. The driving gear 403 is engaged with the driven gear ring 404, so as to drive the connecting seat 405 to rotate. In this way, it can be ensured that the connecting seat 405 stably drives the arm 5 to rotate, and the arm 5 is driven to rotate through the connecting seat 405. The rotation action enables the robot arm to operate in a wider spatial range, thereby improving the flexibility and work efficiency of the robot arm.

[0022] Specifically, Figures 1 to 9 As shown, a stabilizing component 6 is provided at the connection between the connecting seat 405 and the robot arm base 401, and the stabilizing component 6 includes a stabilizing groove 601 provided on the upper end surface of the connecting seat 405, a ball 602 is arranged inside the stabilizing groove 601, a sliding ring 603 is slidably connected to the upper side of the inner part of the stabilizing groove 601, and the upper end surface of the sliding ring 603 is fixedly connected to the connecting seat 405, a limiting groove 606 is provided at the upper end of the inner part of the connecting seat 405, and a limiting wheel 607 is slidably installed inside the limiting groove 606, and a stabilizing support rod 605 is rotatably installed in the middle position of the limiting wheel 607, and the top end of the stabilizing support rod 605 is fixedly connected to the connecting seat 405, and the limiting sliding A connecting groove 604 is fixedly connected between the groove 606 and the stabilizing slide groove 601, and the number of connecting grooves 604 is set in plurality. A one-way liquid inlet valve tube 307 passes through the outer wall of the stabilizing slide groove 601, and a one-way liquid discharge valve tube 308 passes through the bottom end of the limiting slide groove 606. An oil groove 304 is opened inside the locking slide rod 303, and a main pipe 309 passes through the bottom side wall of the oil groove 304. The end of the main pipe 309 away from the oil groove 304 is interconnected with the one-way liquid inlet valve tube 307 and the one-way liquid discharge valve tube 308. A locking support rod 306 is slidably installed inside the upper end of the locking slide rod 303, and a spring 305 is fixedly connected between the locking support rods 306.

[0023] By adopting the above technical solution, when in use, the rotation of the connecting seat 405 can drive the sliding ring 603 to rotate in the stable sliding groove 601. At the same time, a plurality of ball bearings 602 are arranged in the stable sliding groove 601. In this way, through the cooperation of the sliding ring 603, the ball bearings 602 and the stable sliding groove 601, the connecting seat 405 can be driven to rotate, so that the synchronously rotating arm 5 can withstand higher loads and speeds, and can still maintain good stability and anti-deformation ability under high acceleration. When the connecting seat 405 rotates, it can also drive a plurality of stable support rods 605 fixedly installed on the bottom end surface to rotate. The stable support rod 605 can rotate in the limiting sliding groove 606 through the limiting wheel 607 at the bottom end. At the same time, the size of the limiting sliding groove 606 matches the size of the limiting wheel 607. In this way, the limiting wheel 607 can be clamped and rotated in the limiting sliding groove 606. When the arm 5 is overloaded and causes tilting or dumping, the set stable support rod 605 can pull the connecting seat 405 in a tilted state. The design of the stabilizing support rod 605 increases the overall structural stability of the robotic arm. When the arm 5 is overloaded or under the action of other external forces, the stabilizing support rod 605 can effectively resist the tendency of tilting or tipping and maintain the smooth operation of the robotic arm. By adding the stabilizing support rod 605, the carrying capacity of the robotic arm is improved. When bearing a large load, the stabilizing support rod 605 can share part of the weight and reduce the burden on the arm 5. The clamping and rotating design of the limiting wheel 607 in the limiting slide groove 606 makes the robotic arm more stable and smooth during movement. This design reduces the shaking and jittering of the robotic arm during movement, improves the accuracy and efficiency of the operation, and most importantly, the design significantly improves the safety of the robotic arm. When the arm 5 is overloaded or under other abnormal conditions, the stabilizing support rod 605 can quickly play a role to prevent the robotic arm from tilting or tipping, thereby avoiding possible accidents and injuries.

[0024] When the robot arm is working, the driving electric cylinder 301 can be started, and the driving electric cylinder 301 can push the carrying pallet 302 to move upward, and the carrying pallet 302 can slide stably on the locking slide bar 303. When the robot arm tilts, the common support of the locking slide bar 303 and the driving electric cylinder 301 on the carrying pallet 302 can ensure that the carrying pallet 302 has a high bearing capacity, and reduce the squeezing and damage of the robot arm tilting on the carrying pallet 302 to the surrounding equipment. When the carrying pallet 302 slides, the staff needs to manually press the locking support rod 306 on the locking slide bar 303, and the locking support rod 306 can compress the spring 305 and shrink into the locking slide bar 303 at the same time, so that the carrying pallet 302 can slide over the locking support rod 306 and move to the top of the locking support rod 306. It should be noted that when the locking support rod 306 is pressed manually, the carrying pallet 302 slides to the locking support rod 306. When the support rod 306 is at the stop position, the locking support rod 306 can no longer be pressed. When the carrying pallet 302 passes the locking support rod 306, the locking support rod 306 can pop out from the locking slide bar 303 under the action of the spring 305, so that the carrying pallet 302 can be supported by the locking support rod 306, so that the carrying pallet 302 can better support the tipping robotic arm. Such a setting can cooperate with the stabilizing component 6 to further effectively resist the tendency of tilting or tipping, which helps to protect other equipment and structures and avoid chain reactions or further damage caused by the tipping of the robotic arm. This design not only improves the stability of the robotic arm when it tips over, but also enhances the stability of the entire system. The synergistic effect of the locking slide bar 303 and the driving electric cylinder 301 enables the robotic arm to maintain a relatively stable posture even under abnormal circumstances, reducing the safety hazards caused by tipping.

[0025] When the staff manually presses the locking support rod 306 on the locking slide bar 303, the locking support rod 306 can be retracted into the locking slide bar 303. At this time, the locking support rod 306 will squeeze the oil inside the oil tank 304, and the oil inside the oil tank 304 can enter the main pipe 309. The oil in the main pipe 309 can enter the one-way liquid inlet valve pipe 307. The one-way liquid inlet valve pipe 307 is connected to the stable slide groove 601. In this way, the oil can enter the stable slide groove 601. The stable slide groove 601 is flushed with oil, so that the ball 602 and the sliding ring 603 rotating in the stable slide groove 601 can be lubricated, thereby improving the stability of the sliding ring 603 rotating in the stable slide groove 601. At the same time, the stable slide groove 601 is connected The groove 604 and the limiting slide groove 606 are interconnected, so that the oil in the stabilizing slide groove 601 can enter the limiting slide groove 606 through the connecting groove 604, so as to lubricate the limiting wheel 607 and the stabilizing support rod 605 rotating in the limiting slide groove 606. When there is more oil in the stabilizing slide groove 601, the connecting groove 604 and the limiting slide groove 606, the oil can flow back to the oil groove 304 through the one-way drain valve pipe 308 and the main pipe 309, so as to realize the circulation of the oil. The circulating oil can provide sufficient lubrication. Sufficient lubrication can ensure that the various components of the robot arm are closely matched and move smoothly during operation; this helps to reduce looseness or jamming caused by friction and wear, and improve the overall stability of the robot arm.

[0026] Working principle: When in use, place the mechanical frame 1 at a suitable position in the well site. When the position of the mechanical arm needs to be adjusted, start the drive motor 201. The drive motor 201 can drive the ball screw 202 to rotate. The ball screw 202 and the nut seat 205 are continuously filled with intermediates such as balls to reduce friction and improve transmission efficiency. The balls circulate and roll in the spiral grooves of the ball screw 202 and the nut seat 205 to ensure the smooth linear motion of the nut. The linear motion of the nut seat 205 can drive the drive seat 203 to move in the limit groove 204, which can drive the mechanical arm drive assembly 4 on the drive seat 203 to move together. The movement of the mechanical arm drive assembly 4 can drive the position of the arm 5 to move. Thereby, the position of the entire robotic arm can be adjusted. When the robotic arm needs to work, the servo motor 402 is started. The servo motor 402 can drive the driving gear 403 to rotate. The driving gear 403 is meshed with the driven gear ring 404, so as to drive the connecting seat 405 to rotate. In this way, it can be ensured that the connecting seat 405 stably drives the arm 5 to rotate, and the arm 5 is driven to rotate and rotate through the connecting seat 405. The rotation of the connecting seat 405 can drive the sliding ring 603 to rotate in the stable slide groove 601. At the same time, a plurality of balls 602 are arranged in the stable slide groove 601. In this way, through the cooperation of the sliding ring 603, the balls 602 and the stable slide groove 601, the connecting seat 405 can be driven to rotate, so that the synchronously rotating arm 5 can withstand higher loads and speeds. When the connecting seat 405 rotates, it can also drive several stabilizing support rods 605 fixedly installed on the bottom surface to rotate. The stabilizing support rod 605 can rotate in the limiting slide groove 606 through the limiting wheel 607 at the bottom. At the same time, the size of the limiting slide groove 606 matches the size of the limiting wheel 607, so that the limiting wheel 607 can be clamped and rotated in the limiting slide groove 606. When the arm 5 is overloaded and causes tilting or dumping, the set stabilizing support rod 605 can pull the connecting seat 405 in the tilted state. When the mechanical arm is working, the driving electric cylinder 301 can be started. The driving electric cylinder 301 can push the bearing support plate 302 to move upward. The support plate 302 can slide stably on the locking slide bar 303. When the robot arm tilts, the joint support of the locking slide bar 303 and the driving electric cylinder 301 on the support plate 302 can ensure that the support plate 302 has a high load-bearing capacity, and reduce the extrusion and damage of the robot arm tilting on the support plate 302 to the surrounding equipment. When the support plate 302 slides, the staff needs to manually press the locking support rod 306 on the locking slide bar 303, and the locking support rod 306 can compress the spring 305 and shrink into the locking slide bar 303 at the same time, so that the support plate 302 can slide over the locking support rod 306 and move to the top of the locking support rod 306. It should be noted that when the locking support rod 306 is manually pressed, when the support plate 302 slides to the locking support rod 306,The locking rod 306 can be no longer pressed. When the load-bearing support plate 302 passes through the locking rod 306, the locking rod 306 can pop out of the locking slide bar 303 under the action of the spring 305, so that the load-bearing support plate 302 can be supported by the locking rod 306, so that the load-bearing support plate 302 can better support and bear the tilted mechanical arm. Such a setting can cooperate with the stabilizing component 6 to further effectively resist the tendency of tilting or tipping. When the staff manually presses the locking rod 306 on the locking slide bar 303, the locking rod 306 can be retracted into the locking slide bar 303. At this time, the locking rod 306 will squeeze the oil inside the oil tank 304, and the oil inside the oil tank 304 can enter the main pipe 309. The oil in the main pipe 309 can enter the one-way liquid inlet valve pipe 307. The one-way liquid inlet valve pipe 307 is interconnected with the stable slide 601, so that the oil can enter the stable slide 601. The stable slide 601 is flushed with oil, so that the ball 602 and the sliding ring 603 rotating in the stable slide 601 can be lubricated, thereby improving the stability of the sliding ring 603 rotating in the stable slide 601. At the same time, the stable slide 601 is interconnected with the limiting slide 606 through the connecting groove 604, so that the oil in the stable slide 601 can enter the limiting slide 606 through the connecting groove 604, so that the limiting wheel 607 and the stable support rod 605 rotating in the limiting slide 606 can be lubricated. When there is a lot of oil in the stable slide 601, the connecting groove 604 and the limiting slide 606, the oil can flow back to the oil tank 304 through the one-way drain valve pipe 308 and the main pipe 309, thereby realizing the circulation of the oil.
