Description

Technical Field

[0001] The invention relates to the technical field of oil drilling, in particular to an automatic hoisting operation platform for drilling oil pipes. Background Art

[0002] A variety of special equipment is needed during oil drilling, and the construction site requires a high degree of coordination and linkage. Because there are many equipment operators and it is not easy to manage them in a unified manner, there are potential safety hazards. For example, the lifting of the oil pipe requires coordination and cooperation of cranes, pipe rod transportation, and lifting equipment from the stacking, lifting and transportation of the oil pipe to the lifting and lowering of the well. At present, the posture of the oil pipe is prone to change during the lifting process, which poses a threat to the derrick rope and is not convenient for lowering the pipe. When lifting and lowering the well, the joint between the end of the oil pipe and the lifting head of the well repair frame lacks effective connection and needs to be fixed manually, which greatly reduces production efficiency.

[0003] The existing patent (Announcement No.: CN209838341U) is a drilling oil pipe automatic lifting operation platform. Since the automatic lifting operation platform includes an oil pipe storage box, a tower crane manipulator, a pipe rod conveyor, a well repair rack and other equipment that operate in a coherent manner, and the above equipment is uniformly controlled by a PLC controller, thereby integrating a series of construction links from oil pipe stacking, lifting and transportation, pipe lowering and transportation to lifting and lowering into the well, the degree of automation is high, labor is saved, and the operation site is neat and orderly; the oil pipe storage box is used to uniformly hold and transport the oil pipe to avoid oil pollution from damaging the on-site environment. At the same time, steam pipe inlets and oil pollution discharge ports are set at both ends of the storage box to facilitate the cleaning of the oil rod seal and the unified recovery of oil pollution, which meets the requirements of energy conservation and emission reduction; a first angle sensor is set in the slewing platform of the tower crane manipulator, and a second angle sensor is set in the slewing bearing. The PLC controller includes a comparator for receiving feedback signals from the first angle sensor and the second angle sensor. After the rod-type manipulator grabs the oil pipe, the slewing platform and the slewing bearing rotate synchronously in the opposite direction to ensure that the oil pipe is relatively still and the lifting process is safe and stable.

[0004] In the process of implementing the above invention, the inventors found that there are some problems:

[0005] 1. The automation level of the construction process has indeed been improved through equipment such as tower crane manipulators and pipe conveyors, but these equipment will occupy a large area and the construction cost will also increase. Secondly, these equipment require more sensors as support to complete automated transportation, which increases the subsequent maintenance cost; secondly, the use of tower cranes and conveyors requires that clamping and transportation be carried out separately and step by step, resulting in lower overall construction efficiency.

[0006] 2. When the pipes are transported to the derrick, they still need to be clamped by manually pulling the lifting head. At the same time, the lifting and lowering by using steel cables and pulleys is not stable enough. The lifting head and the pipes will continue to swing, and manual control of their movement direction is still required, resulting in relatively low installation efficiency.

[0007] 3. When installing pipe fittings, sometimes the large friction between the threads of the pipe fittings may cause problems such as difficulty in installation or low installation efficiency.

[0008] Therefore, an automatic hoisting operation platform for drilling oil pipes is proposed. Summary of the invention

[0009] The purpose of the present invention is to provide an automatic lifting operation platform for drilling oil pipes, which realizes the tilting movement of the clamp by tilting the motor, and cooperates with the guide block to adjust the angle of the clamp to complete the lateral clamping; utilizes the auxiliary buffer positioning mechanism and the one-way positioning and clamping mechanism to realize the rapid positioning and fixing of the pipe during installation; and drives the oil storage pipe to spray oil through the impact force of the pipe swinging during transportation, so as to lubricate the installation interface, so as to solve the problems raised in the above-mentioned background technology.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] A drilling oil pipe automatic hoisting operation platform comprises a base, a mounting frame, a material storage box and a derrick, wherein a driving motor is obliquely mounted on the mounting frame, a movable frame is slidably mounted on the side wall of the mounting frame, a threaded rod is provided at the output end of the driving motor, a threaded hole matching the threaded rod is provided on the movable frame, a pneumatic clamp is rotatably mounted on the movable frame, a guide block is installed on the base, a guide surface is provided on the guide block, and the guide surface comprises an inclined surface and a horizontal surface, a storage platform is provided on the base, a fixing plate is fixedly mounted on the derrick, and an auxiliary buffer positioning mechanism is installed on the top side wall of the fixing plate:

[0012] The auxiliary buffer positioning mechanism includes two first brackets installed on the fixed plate. A positioning plate is provided on the side of the first bracket away from the fixed plate, and the positioning plate is "C" shaped. A first buffer spring is connected between the positioning plate and the first bracket.

[0013] A one-way positioning and clamping mechanism is installed on the derrick, a clamping and deceleration mechanism is installed on the fixed plate, an auxiliary lubrication mechanism is installed between the fixed plate and the base, the side of the material storage box is funnel-shaped, a guide plate is obliquely arranged on the inner wall of the material storage box, a discharge port is opened on the side wall of the material storage box, a material carrier is slidably provided on the lower outer wall of the material storage box near the discharge port, a plurality of second return springs are connected between the material carrier and the base, a wedge block is fixedly installed on one end of the material carrier away from the mounting frame, a cylinder is provided on the base near the wedge block, and a push plate matching the wedge block is provided at the output end of the cylinder.

[0014] The drive motor is tiltedly arranged on the mounting frame, and the drive motor is used to drive the threaded rod to rotate, and the movable frame and the pneumatic clamp are driven to tilt and move together through the thread transmission. The pneumatic clamp can swing left and right. When encountering the inclined surface of the guide block during the tilting and descending, it will rotate toward the storage box due to the pressure, so that the pneumatic clamp completes the change from the vertical direction to the horizontal direction. In this way, when the pneumatic clamp returns to a high position after clamping the pipe fitting, the pipe fitting can automatically be in a vertical state, realizing the integration of clamping and transportation, simplifying the construction process, thereby improving the construction efficiency. At the same time, there is no high-sensitive component such as a sensor in the mechanism, reducing the construction cost; secondly, when the pipe fitting is pulled to swing toward the derrick, it will directly swing into the positioning plate, and the buffering effect of the first buffer spring will reduce the amplitude of its swing. It is worth noting that since the driving motor drives the thread transmission to lift and lower, the pipe fitting will only swing left and right after being clamped, and will not swing back and forth, that is, the pipe fitting will definitely swing to the position of the positioning plate, realizing the initial positioning of the pipe fitting, thereby improving the subsequent installation efficiency of the pipe fitting. , thereby further improving the construction efficiency; fixing the pipe fittings by pressing, thereby further improving the stability of the pipe fittings during installation; using the clamping and deceleration mechanism to clamp and decelerate the pipe fittings, slowing down their falling speed and improving their falling safety; auxiliary lubrication of the pipe fitting joints by the auxiliary lubrication mechanism, thereby improving the portability of their installation, improving the efficiency of installation, and thus improving the efficiency of construction; starting the cylinder, the cylinder drives the push plate forward to gradually contact the wedge block, and the wedge block is pressed to make the carrier drop, and the carrier no longer blocks the discharge The push plate moves forward, but is still blocked by the pipes on the carrier. The push plate continues to move forward, pushing the pipes on the carrier to the storage table, and the pneumatic clamps the pipes. After the pipes are clamped, they are dragged away. At this time, the pipes in the storage box roll down to the carrier along the guide plate under their own gravity, and the cylinder is started to retract the push plate. It is worth noting that the new pipes fall when the push plate leaves the discharge port, realizing automatic loading. This loading method is simpler and more convenient, with lower loading costs and more convenience, which improves the overall construction efficiency and reduces construction costs.

[0015] Preferably, the one-way positioning and clamping mechanism comprises two mounting plates fixedly mounted on the derrick, two rotating plates are rotatably mounted on the outer walls of the two mounting plates close to each other, a thrust spring is connected between the rotating plate and the mounting plate, a limit plate is fixedly mounted on the two mounting plates, a second bracket is fixedly mounted on the two rotating plates, a pressure plate is provided on the side of the two second brackets away from the rotating plate, and a plurality of second buffer springs are provided between the pressure plate and the second bracket;

[0016] When the pipe fitting swings, it first encounters two second brackets. Under the action of the impact, the two second brackets are rushed open, and the two rotating plates are rotated together, while compressing the two thrust springs. After the pipe fitting completely passes through the two second brackets, it is pressed on the positioning plate, and the first buffer spring continues to be pressed. Under the thrust of the two thrust springs, the two rotating plates rotate and reset, and the two second brackets and the pressure plate are pulled at the same time. After resetting, the two pressure plates will be pressed on the outer wall of the pipe fitting, and cooperate with the positioning plate to position and fix the pipe fitting. It is worth noting that the limit plate will block the rotation of the rotating plate in one direction, so that the rebound amplitude will be very small after the pipe fitting enters the positioning plate, thereby realizing rapid positioning and improving the stability of the pipe fitting during installation, thereby improving the construction efficiency and quality.

[0017] Preferably, the clamping and deceleration mechanism includes two fixed frames symmetrically installed on the fixed plate, each of the two fixed frames is connected to a rotating ring, each of the two rotating rings is rotatably installed with a rotating block, each of the rotating blocks is connected to a clamping block on the side away from the fixed plate, and a deceleration block is provided on the outer wall of the two fixed frames on the side close to each other.

[0018] When the pipe fitting enters the positioning plate, a part of the pipe fitting will also enter between the two clamps. The two clamps clamp the pipe fitting. After the pneumatic clamp releases the pipe fitting, the pipe fitting falls under the action of its own gravity. The friction between the side wall of the pipe fitting and the two clamps drives the clamps to rotate. The clamps will decelerate due to the friction of the fast deceleration, thereby slowing down the descending pipe fitting, making the pipe fitting descend more smoothly, replacing the existing method of lowering it by rope, simplifying the installation steps, and improving the installation efficiency, thereby improving the construction efficiency.

[0019] Preferably, a spring rod is connected between the rotating ring and the fixing frame, and a plurality of spring rods are installed between the rotating block and the clamping block.

[0020] The spring rod is composed of a telescopic rod and a spring. The spring rod on the rotating ring can bring the two clamps closer to achieve the purpose of clamping, and the spring rod between the clamp block and the rotating block can reduce the impact force of the clamp block on the pipe, thereby improving the stability of the clamping and deceleration mechanism, thereby ensuring the realization of the deceleration purpose, and further improving the construction efficiency.

[0021] Preferably, the auxiliary lubrication mechanism includes an oil tank installed on the base, a fixed tube is fixedly inserted on the fixed plate, a piston rod is movably inserted in the fixed tube, a first return spring is connected between the piston rod and the inner wall of the fixed tube, an oil storage tube is fixedly inserted on the fixed plate, a connecting tube is connected between the oil storage tube and the fixed tube, an oil return pipe is provided at one end of the oil storage tube close to the oil tank, and the oil return pipe passes through the top wall of the oil tank and extends to the bottom end of the oil tank, and a nozzle is provided at one end of the oil storage tube away from the oil tank.

[0022] When the pipe fitting is swung into the positioning plate, the pipe fitting will also impact the piston rod. The piston rod compresses the air inside the fixed tube and the first return spring at the same time, and presses the air into the oil storage tube through the connecting tube. The air pressure inside the oil storage tube increases, and the lubricating oil in the oil storage tube is sprayed out through the nozzle and sprayed on the connection of the pipe fitting. After the pressure of the pipe fitting is lost, the first return spring pushes the piston rod back to its original position, so that the internal air pressure in the fixed tube and the oil storage tube is reduced, so that the oil return pipe can draw the lubricating oil from the oil tank into the oil storage tube, realizing cyclic oil suction and oil injection, improving the efficiency of pipe connection, and thus improving the overall construction efficiency.

[0023] Preferably, a one-way valve is provided on the oil return pipe, and a one-way valve is provided between the nozzle and the oil storage pipe.

[0024] The one-way valve on the oil return pipe prevents the lubricating oil in the oil storage pipe from flowing back into the oil tank, while the one-way valve between the nozzle and the oil storage pipe prevents air from entering the oil storage pipe from the nozzle when the oil storage pipe absorbs oil, thereby improving the circulating lubrication effect, further improving the installation efficiency of the pipe fittings, and further improving the overall construction efficiency.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The pneumatic clamp is driven by an oblique motor to move obliquely, and the angle of the pneumatic clamp is adjusted during clamping and transportation in conjunction with the guide block, thus realizing the integration of clamping and transportation, and improving the efficiency of transportation and clamping, while saving construction costs and later maintenance costs. The use of motor transportation also increases stability during transportation.

[0027] 2. When the pipe fittings are placed above the derrick, they are limited in one direction by the one-way positioning and clamping mechanism, and then fixed by the positioning plate and two pressure plates, so as to realize the rapid positioning of the pipe fittings, replacing the manual hand-held positioning, improving the efficiency of positioning while reducing the labor intensity, thereby improving the efficiency of construction.

[0028] 3. When the pipe fitting swings for the first time, it hits the piston rod, so that the piston rod presses out the lubricating oil in the oil storage tube and sprays it on the pipe fitting connection, thereby improving the installation efficiency of the pipe fitting and further improving the construction efficiency.

[0042] See also Figures 1 to 9 The present invention provides an automatic lifting operation platform for drilling oil pipes, and the technical solution is as follows.

[0043] A drilling oil pipe automatic hoisting operation platform comprises a base 1, a mounting frame 2, a material storage box 3 and a derrick 4, a driving motor 10 is obliquely mounted on the mounting frame 2, a movable frame 11 is slidably mounted on the side wall of the mounting frame 2, a threaded rod 12 is provided at the output end of the driving motor 10, a threaded hole matching the threaded rod 12 is provided on the movable frame 11, a pneumatic clamp 13 is rotatably mounted on the movable frame 11, a guide block 14 is installed on the base 1, a guide surface is provided on the guide block 14, and the guide surface includes an inclined surface and a horizontal surface, a storage table 15 is provided on the base 1, a fixed plate 5 is fixedly mounted on the derrick 4, and an auxiliary buffer positioning mechanism 6 is installed on the top side wall of the fixed plate 5:

[0044] The auxiliary buffer positioning mechanism 6 includes two first brackets 601 mounted on the fixed plate 5. A positioning plate 603 is provided on the side of the first bracket 601 away from the fixed plate 5, and the positioning plate 603 is "C" shaped. A first buffer spring 602 is connected between the positioning plate 603 and the first bracket 601.

[0045] Reference Figure 2 , Figure 5 and Figure 7 A driving motor 10 is tiltedly arranged on the mounting frame 2, and the driving motor 10 is used to drive the threaded rod 12 to rotate, and the movable frame 11 and the pneumatic clamp 13 are driven to tilt and move together through the thread transmission action. The pneumatic clamp 13 can be swung left and right. When encountering the inclined surface of the guide block 14 during the tilting and descending, it will rotate toward the storage box 3 due to the pressure, so that the pneumatic clamp 13 completes the change from the vertical direction to the horizontal direction. In this way, when the pneumatic clamp 13 returns to a high position after clamping the pipe fitting, the pipe fitting can automatically be in a vertical state, realizing the integration of clamping and transportation, simplifying the construction process, and thus improving The construction efficiency is improved. At the same time, there are no highly sensitive components such as sensors in the mechanism, which reduces the construction cost. Secondly, when the pipe is pulled and swung toward the derrick 4, it will directly swing into the positioning plate 603, and the first buffer spring 602 will buffer it, reducing the amplitude of its swing. It is worth noting that since the driving motor 10 drives the threaded transmission to lift and lower, the pipe will only swing left and right after being clamped, and will not shake back and forth, that is, the pipe will definitely swing to the position of the positioning plate 603, realizing the initial positioning of the pipe, thereby improving the subsequent installation efficiency of the pipe, thereby further improving the construction efficiency.

[0046] A one-way positioning and clamping mechanism 7 is installed on the derrick 4 .

[0047] The pipe fittings are fixed by means of compression, thereby further improving the stability of the pipe fittings during installation.

[0048] As an embodiment of the present invention, refer to Figure 6 and Figure 7 The one-way positioning and clamping mechanism 7 includes two mounting plates 701 fixedly mounted on the derrick 4, two rotating plates 702 are rotatably mounted on the outer walls of the two mounting plates 701 close to each other, a thrust spring 703 is connected between the rotating plate 702 and the mounting plate 701, a limiting plate 704 is fixedly mounted on the two mounting plates 701, a second bracket 705 is fixedly mounted on the two rotating plates 702, a pressure plate 707 is provided on the side of the two second brackets 705 away from the rotating plate 702, and a plurality of second buffer springs 706 are provided between the pressure plate 707 and the second bracket 705.

[0049] When the pipe fitting swings, it first encounters the two second brackets 705. Under the action of the impact, the two second brackets 705 are rushed open, and the two rotating plates 702 are rotated together, while the two thrust springs 703 are compressed. After the pipe fitting completely passes through the two second brackets 705, it is pressed on the positioning plate 603, while continuing to press the first buffer spring 602. Under the thrust of the two thrust springs 703, the two rotating plates 702 rotate and reset, and at the same time pull the two second brackets 705 and the pressure plate 707. After resetting, the two pressure plates 707 will press on the outer wall of the pipe fitting, and cooperate with the positioning plate 603 to position and fix the pipe fitting. It is worth noting that the limit plate 704 will unidirectionally block the rotation of the rotating plate 702, so that after the pipe fitting enters the positioning plate 603, the rebound amplitude will be very small, thereby achieving rapid positioning, improving the stability of the pipe fitting during installation, and thus improving the construction efficiency and quality.

[0050] A clamping and deceleration mechanism 8 is installed on the fixing plate 5 .

[0051] The clamping and deceleration mechanism 8 is utilized to clamp and decelerate the pipe fitting, thereby slowing down its falling speed and improving its falling safety.

[0052] As an embodiment of the present invention, refer to Figure 8 The clamping and deceleration mechanism 8 includes two fixed frames 801 symmetrically installed on the fixed plate 5, and the two fixed frames 801 are connected with a rotating ring 803. The two rotating rings 803 are rotatably installed with a rotating block 804. The rotating block 804 is connected with a clamping block 806 on the side away from the fixed plate 5, and a deceleration block 805 is provided on the outer wall of the two fixed frames 801 on the side close to each other.

[0053] When the pipe fitting enters the positioning plate 603, a part of the pipe fitting will also enter between the two clamping blocks 806. The two clamping blocks 806 clamp the pipe fitting. After the pneumatic clamp 13 releases the pipe fitting, the pipe fitting falls under the action of its own gravity. The friction force generated between the side wall of the pipe fitting and the two clamping blocks 806 drives the clamping blocks 806 to rotate. The clamping blocks 806 will slow down due to the friction of the deceleration blocks 805, thereby slowing down the descending pipe fitting, making the pipe fitting descend more smoothly, replacing the existing method of lowering it with ropes, simplifying the installation steps, and improving the installation efficiency, thereby improving the construction efficiency.

[0054] As an embodiment of the present invention, refer to Figure 8 A spring rod 802 is connected between the rotating ring 803 and the fixed frame 801, and multiple spring rods 802 are installed between the rotating block 804 and the clamping block 806; the spring rod 802 is connected between the rotating ring 803 and the fixed frame 801 and the air pressure is connected through a conduit. When the pneumatic clamp is loosened, the spring rod 802 is subjected to air pressure, thereby making the clamping block 806 and the pipe fitting tightly connected.

[0055] The spring rod 802 is composed of a telescopic rod and a spring. The spring rod 802 on the rotating ring 803 can bring the two clamping blocks 806 closer to achieve the purpose of clamping, and the spring rod 802 between the clamping block 806 and the rotating block 804 can reduce the impact force of the clamping block 806 on the pipe, thereby improving the stability of the clamping and deceleration mechanism 8. At the same time, by adjusting the air pressure through the controller, the movement rate of the pipe relative to the clamping block 806 can be effectively guaranteed, thereby ensuring the realization of the deceleration purpose, and further improving the construction efficiency.

[0056] An auxiliary lubrication mechanism 9 is installed between the fixing plate 5 and the base 1 .

[0057] The auxiliary lubrication mechanism 9 is used to perform auxiliary lubrication on the pipe joints, thereby improving the portability of the installation, improving the efficiency of the installation, and thus improving the efficiency of the construction.

[0058] As an embodiment of the present invention, refer to Fig. 9 The auxiliary lubrication mechanism includes an oil tank 901 installed on the base 1, a fixed tube 902 is fixedly inserted on the fixed plate 5, a piston rod 903 is movably inserted in the fixed tube 902, a first return spring 904 is connected between the piston rod 903 and the inner wall of the fixed tube 902, an oil storage tube 905 is fixedly inserted on the fixed plate 5, a connecting tube 906 is connected between the oil storage tube 905 and the fixed tube 902, an oil return tube 907 is provided at one end of the oil storage tube 905 close to the oil tank 901, and the oil return tube 907 passes through the top wall of the oil tank 901 and extends to the bottom end of the oil tank 901, and a nozzle 908 is provided at one end of the oil storage tube 905 away from the oil tank 901.

[0059] When the pipe fitting is swung into the positioning plate 603, the pipe fitting will also impact the piston rod 903. The piston rod 903 compresses the air inside the fixed tube 902 and the first return spring 904 at the same time, and presses the air into the oil storage tube 905 through the connecting tube 906. The air pressure inside the oil storage tube 905 increases, and the lubricating oil in the oil storage tube 905 is sprayed out through the nozzle 908 and sprayed on the connection of the pipe fitting. After the pressure of the pipe fitting is lost, the first return spring 904 pushes the piston rod 903 back to its original position, so that the internal air pressure in the fixed tube 902 and the oil storage tube 905 is reduced, so that the return oil pipe 907 can draw the lubricating oil from the oil tank 901 into the oil storage tube 905, thereby realizing cyclic oil suction and oil injection, improving the efficiency of pipe fitting connection, and thus improving the overall construction efficiency.

[0060] As an embodiment of the present invention, refer to Fig. 9 A one-way valve is provided on the oil return pipe 907, and a one-way valve is provided between the nozzle 908 and the oil storage pipe 905.

[0061] The one-way valve on the oil return pipe 907 prevents the lubricating oil in the oil storage pipe 905 from flowing back into the oil tank 901, and the one-way valve between the nozzle 908 and the oil storage pipe 905 prevents air from entering the oil storage pipe 905 from the nozzle 908 when the oil storage pipe 905 absorbs oil, thereby improving the circulating lubrication effect, further improving the installation efficiency of the pipe fittings, and further improving the overall construction efficiency.

[0062] The side of the material storage box 3 is funnel-shaped, and a guide plate 21 is obliquely arranged on the inner wall of the material storage box 3. A discharge port 18 is opened on the side wall of the material storage box 3. A carrier 16 is slidably arranged on the lower outer wall of the material storage box 3 near the discharge port 18. A plurality of second return springs 20 are connected between the carrier 16 and the base 1. A wedge block 17 is fixedly installed at one end of the carrier 16 away from the mounting frame 2. A cylinder 19 is arranged near the wedge block 17 on the base 1, and a push plate matching the wedge block 17 is arranged at the output end of the cylinder 19.

[0063] Start the cylinder 19, which drives the push plate forward and gradually contacts the wedge block 17. The wedge block 17 is pressed to make the carrier 16 drop. The carrier 16 no longer blocks the discharge port 18, but it will still be blocked by the pipe fittings on the carrier 16. The push plate continues to move forward, pushing the pipe fittings on the carrier 16 to move to the storage table 15, and the pneumatic clamp 13 is used to clamp the pipe fittings. After clamping, the pipe fittings are dragged away. At this time, the pipe fittings in the storage box 3 roll down along the guide plate 21 to the carrier 16 under the action of their own gravity, and the cylinder 19 is started to retract the push plate 18. It is worth noting that the new pipe fittings fall when the push plate leaves the discharge port 18, realizing automatic loading. This loading method is simpler and more convenient, and the loading cost is lower and more convenient, which improves the overall construction efficiency and reduces the construction cost.

[0064] Working principle: A driving motor 10 is tiltedly arranged on the mounting frame 2, and the driving motor 10 is used to drive the threaded rod 12 to rotate, and the movable frame 11 and the pneumatic clamp 13 are driven to tilt and move together through the thread transmission. The pneumatic clamp 13 can swing left and right. When encountering the inclined surface of the guide block 14 during the tilting and descending, it will rotate toward the storage box 3 due to the pressure, so that the pneumatic clamp 13 completes the change from the vertical direction to the horizontal direction. In this way, when the pneumatic clamp 13 returns to a high position after clamping the pipe fitting, the pipe fitting can automatically be in a vertical state, realizing the integration of clamping and transportation, simplifying the construction process, thereby improving the efficiency of construction. At the same time, there is no high-sensitive component such as a sensor in the mechanism, reducing the cost of construction; secondly, when the pipe fitting is pulled to swing toward the derrick 4, it will directly swing into the positioning plate 603, and be buffered by the first buffer spring 602 to reduce the amplitude of its swing. It is worth noting that since the driving motor 10 drives the thread transmission to lift and lower, the pipe fitting will only swing left and right after being clamped, and will not swing back and forth. The pipe will swing to the position of the positioning plate 603 when it is in motion, thus achieving the initial positioning of the pipe, thereby improving the subsequent installation efficiency of the pipe, thereby further improving the construction efficiency. When the pipe swings, it first encounters the two second brackets 705. Under the action of the impact, the two second brackets 705 are opened, and the two rotating plates 702 are rotated together, while compressing the two thrust springs 703. After the pipe completely passes through the two second brackets 705, it is pressed on the positioning plate 603, while continuing to press the first buffer spring 602. Under the thrust of the thrust spring 703, the two rotating plates 702 rotate and reset, and at the same time pull the two second brackets 705 and the pressure plate 707. After resetting, the two pressure plates 707 will press on the outer wall of the pipe fitting, and cooperate with the positioning plate 603 to position and fix the pipe fitting. It is worth noting that the limit plate 704 will unidirectionally block the rotation of the rotating plate 702, so that the rebound amplitude of the pipe fitting after entering the positioning plate 603 will be very small, thereby achieving rapid positioning, improving the stability of the pipe fitting during installation, and thus improving the construction efficiency and quality.

[0065] When the pipe fitting enters the positioning plate 603, a part of the pipe fitting will also enter between the two clamping blocks 806. The two clamping blocks 806 clamp the pipe fitting. After the pneumatic clamp 13 releases the pipe fitting, the movement rate of the pipe fitting relative to the clamping blocks 806 can be effectively guaranteed by adjusting the air pressure through the controller. The pipe fitting falls under the action of its own gravity, and the friction force generated between the side wall of the pipe fitting and the two clamping blocks 806 drives the clamping blocks 806 to rotate. The clamping blocks 806 will slow down due to the friction of the deceleration blocks 805, thereby slowing down the descending pipe fitting, making the pipe fitting descend more smoothly, replacing the existing method of lowering it by ropes, simplifying the installation steps, and improving the installation efficiency, thereby improving the construction efficiency.

[0066] When the pipe fitting is swung into the positioning plate 603, the pipe fitting will also impact the piston rod 903. The piston rod 903 compresses the air inside the fixed tube 902 and the first return spring 904 at the same time, and presses the air into the oil storage tube 905 through the connecting tube 906. The air pressure inside the oil storage tube 905 increases, and the lubricating oil in the oil storage tube 905 is sprayed out through the nozzle 908 and sprayed on the connection of the pipe fitting. After the pressure of the pipe fitting is lost, the first return spring 904 pushes the piston rod 903 back to its original position, so that the internal air pressure in the fixed tube 902 and the oil storage tube 905 is reduced, so that the return oil pipe 907 can draw the lubricating oil from the oil tank 901 into the oil storage tube 905, thereby realizing cyclic oil suction and oil injection, improving the efficiency of pipe fitting connection, and thus improving the overall construction efficiency.

[0067] The cylinder 19 is started, and the cylinder 19 drives the push plate forward and gradually contacts the wedge block 17. The carrier 16 is lowered by pressing the wedge block 17. The carrier 16 no longer blocks the discharge port 18, but it will still be blocked by the pipe fittings on the carrier 16. The push plate continues to move forward, pushing the pipe fittings on the carrier 16 to move to the storage table 15, and the pneumatic clamp 13 is used to clamp the pipe fittings. After clamping, the pipe fittings are dragged away. At this time, the pipe fittings in the storage box 3 roll down along the guide plate 21 to the carrier 16 under the action of their own gravity, and the cylinder 19 is started to retract the push plate 18. It is worth noting that the new pipe fittings fall when the push plate leaves the discharge port 18, realizing automatic loading. Moreover, due to the setting of the height of the discharge port 18 and the shape of the carrier, only one pipe fitting moves outward at a time. This loading method is simpler and more convenient, and the loading cost is lower and more convenient, which improves the overall construction efficiency and reduces the construction cost.
