Description

Technical Field

[0001] The invention relates to the technical field of oil extraction, in particular to a deep well drill pipe conveying device. Background Art

[0002] Oil drilling is a critical step in the oil extraction process. It utilizes drilling rigs, which, through the rotation of the drill bit and the applied pressure on bit, break up the underground rock, creating a wellbore from the surface to the oil-bearing strata for subsequent oil extraction operations. During the drilling process, the drill pipe is continuously extended to drill deeper underground.

[0003] With the continuous development of oil drilling technology, automated drilling operations have gradually developed to improve drilling efficiency. Among them, drill pipe transportation is an important link in drilling operations, and its transportation efficiency directly affects the overall drilling efficiency.

[0004] At present, there are patents that have made optimizations to the drill rod conveying link. For example, a drill rod conveying device provided by publication number CN119754713A is provided. In this drill rod conveying device, the horizontal movement of the clamping claw holding the drill rod is achieved through the cooperation of the No. 1 power member, the slide, the No. 1 rack and the No. 1 slide rail, as well as the crossbeam. The vertical movement of the clamping claw holding the drill rod is achieved through the cooperation of the lifting outer cylinder and the lifting inner cylinder. Each time a drill rod is taken, the clamping claw is first moved horizontally to above the drill rod to be grasped, and then the clamping claw is lowered to the specified height through the vertical movement. When transferring, the height of the drill rod is first raised, then moved horizontally, and finally lowered. When grasping again, the clamping claw needs to be moved horizontally, and then moved in the vertical direction. When the number of drill rods becomes smaller and smaller, the stroke of the clamping claw each time it moves up and down increases, which will inevitably increase the time spent by the clamping claw in the vertical direction. There is still room for optimization in this design point.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] Reference Figures 1-9 A deep well drill pipe conveying device includes a cart 1 for conveying drill pipes 101, a material box 2 without end covers is provided on the cart 1, and sliding openings 3 are evenly provided on the side walls of the material box 2 along the height direction thereof, and vertical partitions 4 are symmetrically provided on both sides of each sliding opening 3, and the partitions 4 are fixed to the inner side walls of the material box 2;

[0042] A lifting plate 5 is provided in each of the sliding openings 3, and the end of each lifting plate 5 protrudes outside the material box 2 along the sliding opening 3, and a No. 1 screw rod 6 is provided at the bottom of both sides outside the material box 2, and a No. 1 slider 7 is threadedly connected to the No. 1 screw rod 6, and a No. 2 screw rod 8 is vertically provided on the No. 1 slider 7, and the No. 2 screw rod 8 is threadedly connected to a supporting plate 9, which is used to lift the lifting plate 5 upward;

[0043] A crossbeam 10 is provided across the top of the material box 2, a grabbing mechanism is provided in the middle of the crossbeam 10, a No. 1 hydraulic rod 11 is provided at the end of the crossbeam 10, a No. 2 slider 12 is fixedly connected to the bottom cylinder of the No. 1 hydraulic rod 11, the No. 2 slider 12 slides along the length edge of the top of the material box 2, and a No. 3 screw rod 13 is threadedly connected to the No. 2 slider 12, and the No. 3 screw rod 13 is rotatably connected to a support column 14 provided on the top of the material box 2;

[0044] In this embodiment, the designed No. 1 screw rod 6, No. 2 screw rod 8 and No. 3 screw rod 13 can all be driven to rotate by a reduction motor, and the reduction motor can be controlled by a PLC to achieve the direction and speed control adjustment of the No. 1 screw rod 6, No. 2 screw rod 8 and No. 3 screw rod 13;

[0045] The designed cart 1 can be a powered vehicle body or a non-powered vehicle body. A powered vehicle body means that each wheel of the cart 1 is a hub motor, which is driven by electricity to rotate and realize the movement of the cart 1; a non-powered vehicle body means that the cart 1 is moved by being towed by a tractor.

[0046] The partition 4 is provided to neatly stack the drill rods 101 in the material box 2, making it easier for the grabbing mechanism to grab the drill rods 101. Figure 3-Figure 6 As shown, one end of the drill rod 101 is placed between adjacent partitions 4, and the spacing between two adjacent partitions 4 is adapted to the outer diameter of the end of the drill rod 101;

[0047] The specific operation of the deep well drill pipe conveying device is as follows:

[0048] First, drive the No. 1 screw rod 6 to rotate, and the No. 1 screw rod 6 drives the No. 1 slider 7 to the bottom of a certain lifting plate 5 and pauses, and then drives the No. 2 screw rod 8 to rotate, and the No. 2 screw rod 8 drives the supporting plate 9 to move upward. During the upward movement, the supporting plate 9 lifts the lifting plate 5 upward, and the lifting plate 5 will lift the upper drill rod 101 upward, and the end of the drill rod 101 moves upward along the two adjacent partitions 4. At this time, the drill rod 101 on the top of the supporting plate 9 is lifted to the top of the material box 2, which is the height that the grabbing assembly can grab at this time, and then operate the grabbing assembly, the grabbing assembly grabs the drill rod 101, and then drives the No. 1 hydraulic rod 11, the No. 1 hydraulic rod 11 drives the grabbing assembly and the drill rod 101 to move upward, and then drives the No. 3 screw rod 13 to rotate, and the No. 3 screw rod 1 3 drives the second slide block 12 to slide along the top of the material box 2 and drives the drill rod 101 to the unloading position. At this time, the conveying and transfer of the drill rod 101 can be completed; after the third screw rod 13 drives the second slide block 12 to slide, the second screw rod 8 is driven to continue to rotate, and the second screw rod 8 drives the supporting plate 9 to lift the lifting plate 5 upward. At the same time, the lifting plate 5 pushes the drill rod 101 upward and fills the position where the grabbing assembly has grabbed the unloading drill rod 101. When the grabbing assembly grabs the drill rod 101 again, the grabbing assembly is still at the same height for grabbing operation, instead of extending downward to grab the drill rod 101. There is no need to perform a long vertical movement, which naturally saves the conveying and transfer time of the drill rod 101 and improves the overall operation efficiency of oil drilling.

[0049] Reference Figures 1-12 The grabbing mechanism includes a base block 15 provided on the crossbeam 10, and two No. 2 hydraulic rods 16 are symmetrically provided on the lower end surface of the base block 15. The upper end cylinders of the two No. 2 hydraulic rods 16 are rotatably connected to the lower surface of the base block 15, and the output ends of the two No. 2 hydraulic rods 16 are rotatably connected to the fixed ears 17;

[0050] Two arc-shaped clamping plates 18 are symmetrically provided below the base block 15. A fixing ear 17 is fixed to the outer wall of each clamping plate 18. The end of each clamping plate 18 is rotatably connected to a base plate 19. The base plate 19 extends upward and is fixed to the side wall of the base block 15.

[0051] In this embodiment, the designed grabbing assembly drives the clamping plate 18 to deflect and clamp the drill rod 101 through hydraulic pressure, and the clamping plate 18 is arranged in an arc shape, which can be attached to the surface of the drill rod 101 to tightly wrap and clamp it. Specifically, the two symmetrically arranged clamping plates 18 have their upper edges rotatably connected to the base plate 19. The second hydraulic rod 16 is connected to the external oil pump through a hose. When the output end of the second hydraulic rod 16 is extended, the two clamping plates 18 are driven to approach each other and clamp the drill rod 101. When the output end of the second hydraulic rod 16 is retracted and reset, the two clamping plates 18 are driven to open and release the drill rod 101.

[0052] The grabbing assembly cooperates with the No. 1 hydraulic rod 11. The No. 1 hydraulic rod 11 is used to move the grabbing assembly up and down. When the grabbing assembly grabs the drill rod 101, the No. 1 hydraulic rod 11 drives the grabbing assembly to move downward, so that the two opened clamps 18 are close to the drill rod 101, and the inner top surface of the clamp 18 is attached to the surface of the drill rod 101. When the output end of the No. 2 hydraulic rod 16 is quickly extended to drive the two clamps 18 to approach each other to clamp the drill rod 101, the No. 1 hydraulic rod 11 also drives the grabbing assembly to move upward at the same time, that is, the clamp 18 clamps the drill rod 101 while the No. 1 hydraulic rod 11 performs the upward movement of the grabbing assembly, and uses the time period when the No. 1 hydraulic rod 11 drives the grabbing assembly to move upward to operate the clamp 18 to clamp the drill rod 101, making full use of the time interval and improving efficiency.

[0053] Reference Figures 1-12 The crossbeam 10 is provided with a driving assembly for driving the base block 15 to rotate. The driving assembly includes a driving motor 20 fixed to the crossbeam 10. The output end of the driving motor 20 is fixedly connected to a driving gear 21. The driving gear 21 is meshed with a driven gear ring 22. The driven gear ring 22 is coaxially arranged with the crossbeam 10 and fixedly connected to the end face of the base block 15.

[0054] The base block 15 is rotatably connected to the crossbeam 10, and the driving assembly is used to drive the grasping assembly to deflect around the axis of the crossbeam 10. The driving motor 20 in the driving assembly can also be controlled by the PLC to accurately control the deflection angle of the grasping assembly. When the grasping assembly in the vertical state grasps the drill rod 101, the No. 1 hydraulic rod 11 pushes up the grasping assembly and the drill rod 101, and then moves to one end of the material box 2 through the push of the No. 2 screw rod 8, and then executes the driving assembly. The driving motor 20 drives the active gear to rotate, and the active gear 21 rubs the driven gear ring 22 to rotate. The driven gear ring 22 drives the base block 15 to deflect around the crossbeam 10, so that the drill rod 101 deflects around the axis of the crossbeam 10 to a position above one end of the material box 2, so that the drill rod 101 is away from the upper port of the material box 2, freeing up more operating space and facilitating the removal of the drill rod 101 on the grasping assembly.

[0055] Reference Figures 1-14 The cart 1 is provided with a displacement assembly for driving the material box 2 to move, and the displacement assembly includes a fixed block 23 arranged in the middle position of the bottom of the material box 2, and a fourth screw rod 24 is threadedly connected to the fixed block 23, and the end of the fourth screw rod 24 is rotatably connected to the cart 1;

[0056] The bottom of the material box 2 is symmetrically provided with slides 25 on both sides. The slides 25 are arranged along the length direction of the material box 2. The bottom of the slides 25 is slidably connected to a guide rail 26, which is fixed to the cart 1.

[0057] When the trolley 1 is pulled by the tractor, the drill rods 101 are moved to the front of the trolley 1. When the trolley 1 is pulled by the tractor, the trolley 1 can move smoothly. There are multiple rows of drill rods 101 in the material box 2. When the drill rods 101 near the tail of the trolley 1 in the material box 2 are removed one by one, it is necessary to consider the movement stroke of the drill rods 101 after they are removed from the grabbing assembly. For this purpose, the material plate is slidably connected to the trolley 1. When a row of drill rods 101 near the rear of the trolley 1 in the material box 2 is removed, the material box 2 is driven by the displacement assembly to move toward the tail of the trolley 1 a distance of the diameter of the drill rod 101, so that after each drill rod 101 is removed from the grabbing assembly, the subsequent movement stroke of the drill rod 101 tends to be the same, reducing the movement stroke of the drill rod 101 and improving efficiency. At the same time, the consistency of the transportation process of all drill rods 101 is ensured, so that the oil drilling operation can be carried out stably.

[0058] Reference Figures 1-15 , guide plates 27 for sliding the upper end of the second screw rod 8 are provided on both sides of the top of the material box 2. The guide plates 27 are along the length direction of the material box 2. A strip hole 28 is provided on the guide plate 27. A third slider 29 is provided in the strip hole 28. The third slider 29 is internally rotated to connect the upper end of the second screw rod 8;

[0059] The guide plate 27 is provided to constrain the swing of the No. 2 screw rod 8, improve the stable connection of the No. 2 screw rod 8 to the support plate 9, so that the support plate 9 can stably push up the lifting plate 5; the upper end of the No. 2 screw rod 8 is rotatably connected to the No. 3 slider 29, and the No. 3 slider 29 is slidably connected in the strip hole 28. The strip hole 28 constrains the forward, backward, left and right swing of the No. 2 screw rod 8, so that the No. 2 screw rod 8 can stably push up the support plate 9, thereby improving the upward stability of each row of drill rods 101.

[0060] Reference Figure 1-Figure 3 A horizontal plate 30 is provided between the two support columns 14 in the longitudinal direction of the top of the material box 2. A sliding hole 31 is provided on the horizontal plate 30 in the longitudinal direction. The horizontal plate 30 is placed on the upper surface of the cylinder body of the No. 1 hydraulic rod 11. The output end of the No. 1 hydraulic rod 11 passes through the sliding hole 31 upward.

[0061] The support column 14 cooperates with the cross plate 30 to constrain the stability of the No. 1 hydraulic rod 11 on the crossbeam 10, the grabbing assembly and the drill rod 101. Specifically, the output end of the No. 1 hydraulic rod 11 is slidably connected in the sliding hole 31, which can constrain the swing of the No. 1 hydraulic rod 11 and improve the stability of the drill rod 101 during the grabbing and conveying process, that is, the stability of the grabbing assembly together with the drill rod 101 moving along the length of the material box 2.

[0062] Reference Figure 7 , the upper ends of the adjacent partitions 4 are arranged in a flared shape, and the lower sides of the upper ends of the adjacent partitions 4 are arranged in a constricted shape;

[0063] Considering the subsequent filling of the drill rods 101, that is, filling the drill rods 101 into the material box 2, first drive the lifting plate 5 to move up to the top of the material box 2, and stack the drill rods 101 one by one. After each drill rod 101 is placed, the lifting plate 5 moves down by a diameter of the drill rod 101, so that the drill rods 101 can be smoothly filled into the material box 2, and the upper ends of the two adjacent partitions 4 are expanded, as shown in FIG. Figure 7 As shown, the entrance for placing the drill rod 101 between two adjacent partitions 4 is enlarged to facilitate the loading of the drill rod 101;

[0064] The accurate clamping of each drill rod 101 by the clamping plate 18 is also taken into consideration. That is, after each time the lifting plate 5 lifts the drill rod 101, the top drill rod 101 can be centered between the adjacent partitions 4, ensuring that the middle position of the outer ring of the end of the drill rod 101 to be clamped by the clamping plate 18 can be opposite to the middle position of the two adjacent clamping plates 18, and the clamping plate 18 stably clamps the drill rod 101. For this purpose, a constriction is set at the lower side of the upper end of the partition 4, such as Figure 7 As shown, the axis of the drill rod 101 is centered between two adjacent partitions 4.

[0065] Reference Figure 5 、 Figure 6 and Figure 10 , a chute 32 is provided at the bottom of each second slider 12, and the top length edge of the material box 2 is embedded in the chute 32;

[0066] A slide groove 32 adapted to the top edge of the material box 2 is provided at the bottom of the No. 2 slider 12, and the top edge of the material box 2 is embedded in the slide groove 32, thereby improving the stability of the No. 2 slider 12 during sliding, thereby improving the stability of the No. 1 hydraulic rod 11, the grab assembly and the drill rod 101 during horizontal movement.

[0067] Reference Figure 8 and Figure 9 , a groove 33 is formed on the upper surface of each supporting plate 9, and the end of the lifting plate 5 is embedded in the groove 33;

[0068] The groove 33 is used to constrain the cooperation between the support plate 9 and the lifting plate 5. When the support plate 9 moves to the bottom of the lifting plate 5, the support plate 9 moves up through the second screw 8, and the end of the lifting plate 5 is embedded in the groove 33, constraining the relative sliding between the support plate 9 and the lifting plate 5. In the process of the support plate 9 pushing the lifting plate 5, the movement process of the lifting plate 5 and the support plate 9 is more stable.

[0069] Reference Figure 1-Figure 3 A clearance opening 34 is provided at the middle position of the rear end of the cart 1 .

[0070] A clearance opening 34 is provided at the rear end of the cart 1, that is, the tail end of the cart 1. A structure for fixing the cart 1 can be provided in the clearance opening 34, such as a plug rod or the like, which is inserted into the clearance opening 34 and fixed to the ground to fix the cart 1, or a support rod for temporarily lifting the drill rod 101 on the grabbing assembly can be provided in the clearance opening 34. The support rod can be composed of an electric push rod or a hydraulic cylinder and a top plate. The top plate is pushed up and temporarily lifts the suspended drill rod 101 to improve the stability of the drill rod 101 in this state and the safety of the oil drilling operation.

[0071] Working principle: First, drive the No. 1 screw rod 6 to rotate, and the No. 1 screw rod 6 drives the No. 1 slider 7 to the bottom of a certain lifting plate 5 and pauses, then drive the No. 2 screw rod 8 to rotate, and the No. 2 screw rod 8 drives the support plate 9 to move upward. During the upward movement, the support plate 9 lifts the lifting plate 5 upward, and the lifting plate 5 will lift the upper drill rod 101 upward, and the end of the drill rod 101 moves upward along the two adjacent partitions 4. At this time, the drill rod 101 on the top of the support plate 9 is lifted to the top of the material box 2, which is the height that the grabbing component can grasp at this time. Then operate the grabbing component, and the adjacent two splints 18 approach each other and grasp the drill rod 101, then drive the No. 1 hydraulic rod 11, and the No. 1 hydraulic rod The rod 11 drives the grabbing assembly and the drill rod 101 to move upward, and then drives the No. 3 screw rod 13 to rotate. The No. 3 screw rod 13 drives the No. 2 slider 12 to slide along the top of the material box 2 and drives the drill rod 101 to the unloading position. Then the driving assembly is operated, and the driving motor 20 drives the active gear to rotate. The active gear rubs the driven gear ring 22 to rotate. The driven gear ring 22 drives the base block 15 to deflect around the beam 10, so that the drill rod 101 deflects around the axis of the beam 10 to a position above one end of the material box 2, so that the drill rod 101 is away from the upper port of the material box 2, freeing up more operating space, and facilitating the removal of the drill rod 101 on the grabbing assembly. At this time, the transportation and transfer of the drill rod 101 can be completed.
