During the placement or detachment process of the pipe fittings, there is a large noise, and the pipe fittings are prone to bumps and frictions, resulting in damage to the pipe fittings. Moreover, the rolling positions of the pipe fittings are random, posing a relatively large potential safety hazard. Summary of the Invention

[0003] The present application aims to at least solve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present application provides a pipe fitting moving device.

[0005] A second aspect of the present application provides a pipe fitting transporting device.

[0006] The technical solution of the first aspect of the present application provides a pipe fitting moving device, which includes a connecting seat, a connecting rod assembly, and a bracket. The connecting seat is provided with a mounting surface, and the plane where the mounting surface is located is the first plane. The connecting rod assembly includes a first support rod and a second support rod. One end of the first support rod is rotatably connected to the connecting seat, and the first end of the second support rod is connected to the other end of the first support rod. The bracket is used for placing pipe fittings, the second end of the second support rod is connected to the bracket, and the connecting rod assembly is used to drive the bracket to move relative to the connecting seat. Wherein, the second support rod and the first support rod form a first included angle, and when the second support rod is on the side of the first plane close to the first support rod, the distance from the second end of the second support rod to the first plane is less than the distance from the first end of the second support rod to the first plane.

[0007] In this technical solution, the pipe fitting moving device provided by the present application includes a connecting seat, a connecting rod assembly, and a bracket. The pipe fitting moving device is used for a pipe fitting transporting device. Exemplarily, the pipe fitting transporting device can be a power catwalk in oilfield workover operations. The pipe fitting moving device is used to place or detach pipe fittings from the pipe fitting transporting device.

[0008] The connecting rod assembly includes a first support rod and a second support rod. One end of the first support rod is rotatably connected to the connecting seat, the first end of the second support rod is connected to the other end of the first support rod, the second end of the second support rod is connected to the bracket, both ends of the connecting rod assembly are connected to the connecting seat and the bracket respectively, and the connecting rod assembly can rotate relative to the connecting seat so that the bracket moves relative to the connecting seat. When the first support rod rotates relative to the connecting seat, the second support rod drives the bracket to rotate relative to the connecting seat.

[0009] The bracket is used to place pipe fittings, enabling the pipe fittings to move along with the bracket, so that the pipe fittings can approach or move away from the pipe fitting transportation device, and further enabling the pipe fittings to be placed on or detached from the pipe fitting transportation device, enabling the bracket to perform operations such as swinging to pick up the pipe, holding the pipe, and lifting the pipe.

[0010] The connecting seat is provided with a mounting surface, which is located at the bottom of the connecting seat. The plane where the mounting surface is located is the first plane, and the first support rod is located above the first plane. The second support rod has a first included angle with the first support rod. When the second support rod is on the side of the first plane close to the first support rod, that is, when the second support rod is above the first plane, the distance from the second end of the second support rod to the first plane is less than the distance from the first end of the second support rod to the first plane, making the second end of the second support rod lower than the first end of the second support rod, that is, the end of the second support rod connected to the bracket is closer to the first plane relative to the first end, causing the second support rod to extend in the direction close to the first plane, reducing the height of the bracket, and further reducing the required height for placing pipe fittings on the bracket, facilitating the operation of the relevant device for loading and unloading pipe fittings on the bracket.

[0011] In this way, the link assembly drives the bracket to move, enabling the pipe fittings accommodated on the bracket to move along with the bracket according to a preset trajectory, and further enabling the pipe fittings to be placed on or detached from the pipe fitting transportation device, making the movement process of the pipe fittings stable and safe, reducing the bumps and frictions generated during the movement of the pipe fittings, and reducing the noise during the movement of the pipe fittings.

[0015] The first support rod is moved by changing the length of the telescopic member to drive the first support rod to rotate relative to the connecting seat. When the telescopic member extends, the first support rod rotates counterclockwise relative to the connecting seat, and when the telescopic member contracts, the first support rod rotates clockwise relative to the connecting seat.

[0016] In this way, through the telescopic movement of the telescopic member, the first rod is driven to rotate relative to the connecting seat, and then the first rod drives the second rod and the bracket to rotate, changing the position of the bracket placed thereon, so that the bracket approaches or moves away from the pipe conveying device.

[0031] In this way, the first rod, the telescopic member, and the third rod are respectively rotatably connected to the first connecting part or the second connecting part, which simplifies the structure of the connecting seat and reduces the cost of the pipe fitting moving device.

Detailed implementation manners

[0056] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.

[0057] Next, refer to Figures 1 to 9 to describe the pipe fitting moving device 10 and the pipe fitting transportation device according to some embodiments of the present application.

[0058] An embodiment of the first aspect of the present application provides a pipe fitting moving device 10, as shown in Figure 1 and Figure 2As shown, the pipe fitting moving device 10 includes: a connecting seat 100, a connecting rod assembly 200, and a bracket 400. The connecting seat 100 is provided with a mounting surface 160, and the plane where the mounting surface 160 is located is the first plane. The connecting rod assembly 200 includes: a first rod 210 and a second rod 220. One end of the first rod 210 is rotatably connected to the connecting seat 100, and the first end of the second rod 220 is connected to the other end of the first rod 210. The bracket 400 is used to place the pipe fitting, the second end of the second rod 220 is connected to the bracket 400, and the connecting rod assembly 200 is used to drive the bracket 400 to move relative to the connecting seat 100. Wherein, the second rod 220 and the first rod 210 have a first included angle, and when the second rod 220 is located on the side of the first plane close to the first rod 210, the distance between the second end of the second rod 220 and the first plane is less than the distance between the first end of the second rod 220 and the first plane.

[0059] In this embodiment, the pipe fitting moving device 10 provided in the present application includes a connecting seat 100, a connecting rod assembly 200, and a bracket 400. The pipe fitting moving device 10 is used for a pipe fitting transportation device. Exemplarily, the pipe fitting transportation device can be a power catwalk in oilfield workover operations. The pipe fitting moving device 10 is used to place or remove the pipe fitting from the pipe fitting transportation device.

[0060] The connecting rod assembly 200 includes a first rod 210 and a second rod 220. One end of the first rod 210 is rotatably connected to the connecting seat 100, the first end of the second rod 220 is connected to the other end of the first rod 210, the second end of the second rod 220 is connected to the bracket 400, both ends of the connecting rod assembly 200 are connected to the connecting seat 100 and the bracket 400 respectively, and the connecting rod assembly 200 can rotate relative to the connecting seat 100 so that the bracket 400 moves relative to the connecting seat 100. When the first rod 210 rotates relative to the connecting seat 100, the second rod 220 drives the bracket 400 to rotate relative to the connecting seat 100.

[0061] The bracket 400 is used to place the pipe fitting so that the pipe fitting can move along with the bracket 400. The movement paths of the pipe fitting and the bracket 400 are the same, so that the pipe fitting can approach or move away from the pipe fitting transportation device, and further the pipe fitting can be placed or removed from the pipe fitting transportation device, enabling the bracket 400 to perform operations such as swinging and fishing for pipes, holding pipes, and lifting pipes.

[0062] The connecting seat 100 is provided with a mounting surface 160. The mounting surface 160 is located at the bottom of the connecting seat 100, the plane where the mounting surface 160 is located is the first plane, and the first rod 210 is located above the first plane. As Figure 2As shown, the second rod 220 and the first rod 210 have a first included angle A. When the second rod 220 is on the side of the first plane close to the first rod 210, that is, when the second rod 220 is above the first plane, the distance between the second end of the second rod 220 and the first plane is less than the distance between the first end of the second rod 220 and the first plane, making the second end of the second rod 220 lower than the first end of the second rod 220. That is, the end of the second rod 220 connected to the bracket 400 is closer to the first plane than the first end, causing the second rod 220 to extend in the direction close to the first plane, reducing the height of the bracket 400, and further reducing the required height for placing pipe fittings on the bracket 400, facilitating the operation of upper and lower pipe fittings on the bracket 400 by related devices.

[0063] In this way, the link assembly 200 drives the bracket 400 to move, enabling the pipe fittings accommodated on the bracket 400 to move along a preset trajectory following the bracket 400. Furthermore, the pipe fittings can be placed on or detached from the pipe fitting transportation device, making the movement process of the pipe fittings stable and safe, reducing the bumps and frictions generated during the movement of the pipe fittings, and reducing the noise during the movement of the pipe fittings. And by reducing the height of the bracket 400 through the second rod 220, the convenience of the bracket 400 when loading and unloading pipe fittings is improved.

[0064] In some embodiments provided by the present application, as Figure 1 and Figure 7 shown, optionally, the pipe fitting moving device 10 provided by the present application further includes: a telescopic member 300. One end of the telescopic member 300 is rotatably connected to the connecting seat 100, and the other end of the telescopic member 300 is rotatably connected to the first rod 210 to drive the first rod 210 to rotate relative to the connecting seat 100.

[0065] In this embodiment, the pipe fitting moving device 10 further includes a telescopic member 300, and the telescopic member 300 can change the length of the telescopic member 300 through telescopic movement. One end of the telescopic member 300 is rotatably connected to the connecting seat 100, and the other end of the telescopic member 300 is rotatably connected to the first rod 210. Exemplarily, the telescopic member 300 can be an oil cylinder, the trunnion hinge point of the rodless side of the oil cylinder is rotatably connected to the connecting seat 100, and the trunnion hinge point of the rod side of the oil cylinder is rotatably connected to the first rod 210.

[0066] The first rod 210 is moved by changing the length of the telescopic member 300 to drive the first rod 210 to rotate relative to the connecting seat 100. When the telescopic member 300 extends, the first rod 210 rotates counterclockwise relative to the connecting seat 100. When the telescopic member 300 contracts, the first rod 210 rotates clockwise relative to the connecting seat 100.

[0067] In this way, through the telescopic movement of the telescopic member 300, the first support rod 210 is driven to rotate relative to the connecting seat 100, and then the first support rod 210 drives the second support rod 220 and the bracket 400 to rotate, changing the position of the bracket 400 placed thereon, so that the bracket 400 approaches or moves away from the pipe transportation device.

Specifically, the link assembly 200 further includes a first connecting member 230 and a second connecting member 240. The first connecting member 230 is respectively connected to two adjacent first support rods 210, and the second connecting member 240 is respectively connected to two adjacent second support rods 220. The structural strength of the link assembly 200 is enhanced, the supporting force of the link assembly 200 on the bracket 400 is increased, and further the lifting force of the bracket 400 on the pipe is increased.

[0070] At least a part of the telescopic member 300 is located between the two first support rods 210, so that the driving force of the telescopic member 300 on the link assembly 200 is located between the two first support rods 210, and further the driving effect of the telescopic member 300 on the link assembly 200 is more stable.

[0071] In this way, the number of both the first support rods 210 and the second support rods 220 is multiple, at least a part of the telescopic member 300 is located between the two first support rods 210, the structural strength of the link assembly 200 is enhanced, the lifting force of the bracket 400 on the pipe is increased, the driving effect of the telescopic member 300 on the link assembly 200 is more stable, and further the stability of the link assembly 200 and the bracket 400 is improved.

[0072] In some embodiments provided by the present application, as Figure 1 and Figure 3As shown, optionally, the pipe fitting moving device 10 provided in the present application further includes: a third support rod 500 and a fourth support rod 600.

[0073] In this embodiment, the pipe fitting moving device 10 further includes a third support rod 500 and a fourth support rod 600. The third support rod 500 and the fourth support rod 600 are located on one side of the link assembly 200. One end of the third support rod 500 is rotatably connected to the connection seat 100. The first end 610 of the fourth support rod is connected to the other end of the third support rod 500, and the second end of the fourth support rod 600 group is connected to the bracket 400, so that the bracket 400 is connected to the connection seat 100 through the third support rod 500 and the fourth support rod 600. Furthermore, the fourth support rod 600 drives the bracket 400 to rotate following the third support rod 500.

[0074] As Figure 3 shown, the third support rod 500 and the fourth support rod 600 have a second included angle B, and the second included angle B is equal to the first included angle A. Since the first support rod 210 and the third support rod 500 have the same extending direction, the extending angles of the second support rod 220 and the fourth support rod 600 are the same, and the movement paths of the fourth support rod 600 and the second support rod 220 match, so that the rotation of the bracket 400 relative to the connection seat 100 is stable.

[0075] In this way, the bracket 400 is connected to the connection seat 100 through the third support rod 500 and the fourth support rod 600, enhancing the connection strength between the bracket 400 and the connection seat 100, increasing the lifting force of the bracket 400 on the pipe fitting, and enabling the bracket 400 to rotate stably relative to the connection seat 100 under the drive of the second support rod 220 and the fourth support rod 600.

[0076] In some embodiments provided by the present application, as Figure 4 shown, optionally, the bracket 400 includes: a bracket 410 and a first connecting rod 420. The bracket 410 is connected to the second support rod 220. Both ends of the first connecting rod 420 are respectively connected to the bracket 410 and the second end 620 of the fourth support rod, and there is a spacing between the second end 620 of the fourth support rod and the bracket 410.

[0077] In this embodiment, the bracket 400 includes a support 410 and a first connecting rod 420. The first connecting rod 420 is located on the side of the support 410 close to the fourth strut 600. The support 410 is connected to the second strut 220. Both ends of the first connecting rod 420 are respectively connected to the support 410 and the second end 620 of the fourth strut, so that there is a spacing between the second end 620 of the fourth strut and the support 410. Specifically, the first connecting rod 420 is horizontally arranged, so that there is a spacing between the second end 620 of the fourth strut and the support 410 in the horizontal direction. The link assembly 200, the connecting seat 100, the bracket 400, the third strut 500 and the fourth strut 600 form a link mechanism of a parallelogram.

[0078] In this way, the fourth strut 600 and the second strut 220 simultaneously provide supporting force and driving force for different positions of the bracket 400 in the horizontal direction, so that the force on the bracket 400 in the horizontal direction is balanced, and the bracket 400 always maintains a horizontal lifting state during the process of moving up and down the pipes. Furthermore, the pipe fittings accommodated on the bracket 400 are in a horizontal state, avoiding the sliding of the pipe fittings caused by the inclination of the bracket 400.

[0079] In some embodiments provided by the present application, as Figure 1 , Figure 5 and Figure 6 shown, optionally, the connecting seat 100 includes: a base 110, a first connecting portion 120 and a second connecting portion 130. The first connecting portion 120 is provided on the base 110, and the first connecting portion 120 is rotatably connected to the first strut 210. The second connecting portion 130 is provided on the base 110, and the second connecting portion 130 is rotatably connected to the telescopic member 300. The third strut 500 is rotatably connected to the first connecting portion 120 or the second connecting portion 130.

[0080] In this embodiment, the connecting seat 100 includes a base 110, a first connecting portion 120 and a second connecting portion 130. The mounting surface 160 is provided on the upper surface of the bottom plate of the base 110. The first connecting portion 120 is provided on the base 110, and the first connecting portion 120 is rotatably connected to the first strut 210. The second connecting portion 130 is provided on the base 110, and the second connecting portion 130 is rotatably connected to the telescopic member 300. The second connecting portion 130 is located below the first connecting portion 120, so that the telescopic member 300 can easily provide a supporting force for the first strut 210 in its extending direction. Specifically, the first connecting portion 120 and the second connecting portion 130 can be connecting shafts, and the base 110 is provided with mounting holes 150, and the connecting shafts are inserted into the mounting holes 150.

[0081] The third strut 500 is rotatably connected to the first connecting portion 120 or the second connecting portion 130, so that the structure of the connecting seat 100 is simplified, the components and installation procedures related to the connecting seat 100 are reduced, and thus the material cost and installation cost of the pipe fitting moving device 10 are reduced.

[0082] In this way, the first rod 210, the telescopic member 300, and the third rod 500 are respectively rotatably connected to the first connecting portion 120 or the second connecting portion 130, which simplifies the structure of the connecting seat 100 and reduces the cost of the pipe fitting moving device 10.

[0083] In some embodiments provided by the present application, such as Figure 1 , Figure 8 and Figure 9 as shown, optionally, the pipe fitting moving device 10 provided by the present application is used for a pipe fitting transportation device, and further includes: a mounting seat 700 and an inner cylinder 800. The mounting seat 700 is used for connecting with the pipe fitting transportation device. The inner cylinder 800 is connected to the mounting seat 700. The connecting seat 100 further includes an outer cylinder 140. The outer cylinder 140 is connected to the bottom wall of the base 110. The outer cylinder 140 is sleeved on the inner cylinder 800, and the outer cylinder 140 is used for rotatably connecting with the inner cylinder 800.

[0084] In this embodiment, the pipe fitting moving device 10 provided by the present application is used for a pipe fitting transportation device, and further includes: a mounting seat 700 and an inner cylinder 800. The mounting seat 700 is used for connecting with the pipe fitting transportation device. Exemplarily, the mounting seat 700 can be installed on the skid-shaped base of the power catwalk, so that the pipe fitting moving device 10 and the pipe fitting transportation device form an integral body, which is convenient for overall hoisting and transportation. The inner cylinder 800 is connected to the mounting seat 700. Specifically, the inner cylinder 800 and the mounting seat 700 form a steel structure welded part.

[0085] The connecting seat 100 further includes an outer cylinder 140. The outer cylinder 140 is connected to the bottom wall of the base 110. The outer cylinder 140 is sleeved on the inner cylinder 800, and the outer cylinder 140 is used for rotatably connecting with the inner cylinder 800. Specifically, a roller thrust bearing is provided between the top of the inner cylinder 800 and the bottom wall of the base 110 to reduce the frictional resistance between the inner cylinder 800 and the base 110. So that the outer cylinder 140 can rotate relative to the inner cylinder 800 along the axis, and the connecting seat 100 drives the link assembly 200 and the bracket 400 to rotate relative to the axis of the outer cylinder 140, and the positions and moving directions of the link assembly 200 and the bracket 400 change, so that the pipe fitting moving device 10 can move pipe fittings in different positions, and further enable the pipe fitting moving device 10 to switch the movement direction required for moving the pipe fitting up and down when it is respectively located at the working positions on the left and right sides of the pipe fitting transportation device.

[0086] In this way, the mounting seat 700 is connected to the pipe fitting transportation device, which is convenient for the hoisting and transportation of the pipe fitting moving device 10 and the pipe fitting transportation device. The outer cylinder 140 is used for rotatably connecting with the inner cylinder 800, so that the pipe fitting moving device 10 can switch the movement direction required for moving the pipe fitting up and down, avoiding installing mirror-image pipe fitting moving devices 10 on the left and right sides of the pipe fitting transportation device, and reducing the weight and manufacturing cost of the pipe fitting transportation device.

[0087] In some embodiments provided by the present application, such as Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 shown, optionally, the pipe fitting moving device 10 provided by the present application further includes a fixing member 900. The fixing member 900 is respectively connected to the outer cylinder 140 and the inner cylinder 800. The fixing member 900 passes through the mounting hole 150 of the outer cylinder 140 and the through hole 810 of the inner cylinder 800, and the fixing member 900 limits the outer cylinder 140.

[0088] In this embodiment, the pipe fitting moving device 10 further includes a fixing member 900. The fixing member 900 is respectively connected to the outer cylinder 140 and the inner cylinder 800. The fixing member 900 passes through the mounting hole 150 of the outer cylinder 140 and the through hole 810 of the inner cylinder 800. Exemplarily, the fixing member 900 may be a connecting bolt. The outer cylinder 140 rotates relative to the inner cylinder 800. When the connecting seat 100 rotates to the working position, the mounting hole 150 and the through hole 810 are aligned, and the fixing member 900 passes through the mounting hole 150 and the through hole 810, preventing the outer cylinder 140 from continuing to rotate, so that the fixing member 900 limits the outer cylinder 140.

[0089] In this way, the fixing member 900 limits the outer cylinder 140, preventing the outer cylinder 140 from rotating during the movement of the bracket 400, and improving the stability of the bracket 400 during the process of moving the pipe fitting.

[0090] In some embodiments provided by the present application, such as Figure 4 shown, optionally, the bracket 400 further includes a limiting portion 430. The limiting portion 430 is connected to the bracket 410. The limiting portion 430 forms a receiving space 431. The limiting portion 430 is used for receiving the pipe fitting and limiting the pipe fitting.

[0091] In this embodiment, the bracket 400 further includes a limiting portion 430. The limiting portion 430 is connected to the bracket 410. The limiting portion 430 forms a receiving space 431. Exemplarily, the limiting portion 430 may include a baffle and a supporting plate. The baffle and the supporting plate are configured into a groove structure, and the groove structure forms the receiving space 431. The pipe fitting is received in the receiving space 431, and the limiting portion 430 limits the pipe fitting.

[0092] In this way, the limiting portion 430 limits the pipe fitting, preventing the pipe fitting from slipping, and improving the stability of the bracket 400 in lifting the pipe fitting.

[0094] It should be noted that the pipe fitting transportation device includes a slideway, and the pipe fitting transportation device can move in the up and down direction. The workover site also includes a pipe bridge, an oil receiving box, a yard worker or an automatic pipe arranging device.

[0095] During the operation of pulling out pipes in workover, the working steps of the pipe fitting moving device 10 are as follows:

[0096] 1. When the pipe fitting moving device 10 is in the working position of the pipe fitting transportation device, the telescopic member 300 moves, so that the bracket 400 rotates to directly above the extension line of the slideway of the pipe fitting transportation device.

[0097] 2. The pipe fitting is located on the pipe fitting transportation device. The pipe fitting transportation device moves downward, conveys the pipe fitting into the limiting part 430 of the pipe fitting moving device 10, and the pipe fitting transportation device continues to descend until the pipe fitting is completely separated from the pipe fitting transportation device.

[0098] 3. The pipe fitting moving device 10 holds the pipe fitting and swings it towards the pipe bridge, sends the pipe fitting to the oil receiving box, and arranges the pipe fittings through the yard worker or the automatic pipe arranging device to complete the pipe pulling operation.

[0101] 2. The bracket 400 swings upward to hold up the pipe fitting. When the pipe fitting reaches directly above the pipe fitting transportation device, the bracket 400 stops moving.

[0102] 3. The pipe fitting transportation device starts to work to complete the pipe running operation.
