Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drill pipe conveying, in particular to a drill pipe storage platform and a pipe feeding device. BACKGROUND

[0002] Drill pipe is an indispensable key tool component in the construction process of oil and gas drilling, geological exploration, etc. Due to the large depth of drilling operation, a large number of drill pipes are required, and each drill pipe is heavy and long. How to safely and efficiently store and supply drill pipes in sequence in the limited space of the well site becomes an important link affecting the operation efficiency. In order to facilitate the storage and use of drill pipes, a support type drill pipe storage platform with an inclined platform is commonly used in the prior art. During operation, multiple drill pipes are transported to the platform of the storage platform by a conveying device, and are rolled along the inclined surface to the lower end by relying on their own gravity, and are collected at the material taking end. In order to facilitate the grabbing of the mechanical arm, an independent lifting device is usually arranged at the lower end of the inclined surface of the platform, which is used to lift the lowest drill pipe to a certain height to separate it from the adjacent drill pipe, so as to avoid interference or collision during clamping.

[0003] However, the existing drill pipe storage and pipe feeding mode still has some deficiencies. First, the pipe feeding process is sequentially executed, that is, after the mechanical arm takes out the drill pipe, the lifting device needs to be reset to receive a new drill pipe and be lifted to perform the next pipe feeding. This intermittent working mode has an idle waiting time, especially when multiple drill pipes need to be taken out continuously, the cycle period is long and the efficiency is low. Second, the drill pipe completely relies on gravity to accelerate and roll down on the inclined platform, and the impact force at the end is large, which not only produces a lot of noise, but also is more likely to cause rigid collision with the adjacent drill pipe or the platform baffle, thereby causing damage to the drill pipe thread joint or surface corrosion coating and shortening the service life of the drill pipe. In addition, when the sliding potential energy is too large, the drill pipe is prone to tilt and jam during sliding due to different rolling steps, resulting in feeding failure. Moreover, there is a lack of effective cooperative control among the lifting device, the platform and the clamping mechanism, the motion correlation is low, the whole system has high energy consumption, the intelligent degree is insufficient, and it cannot meet the requirements of modern drilling operation for automation, high efficiency and high safety. SUMMARY

[0004] The present application provides a drill pipe storage platform and a pipe feeding device to solve the above technical problems.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0006] A drill pipe storage platform and a pipe feeding device, comprising a storage rack for placing drill pipes, and a support frame arranged at the bottom of the storage rack, further comprising a lifting group and a bracket, the end of the storage rack is rotatably installed on the support frame, the lifting group is arranged below the bracket and connected with the bracket, and the top end of the bracket is provided with a containing groove for transversely placing drill pipes;

[0007] The bracket comprises a positioning horizontal plate and a V-shaped frame plate, a vertical cutting line is formed on one side of the V-shaped frame plate along the central axis, the cutting line cuts the V-shaped frame plate into a main splicing plate and a secondary splicing plate, the main splicing plate and the secondary splicing plate are connected through a first elastic component, the main splicing plate is arranged at both ends of the positioning horizontal plate, the bottom of the positioning horizontal plate is fixedly connected with an output shaft of a lifting group, a limiting baffle is arranged on the outer side wall of the secondary splicing plate, and a limiting baffle is arranged on the shell of the lifting group. The separable V-shaped frame plate makes the bracket a dynamic separable composite, and the accommodating grooves can accommodate two drill rods simultaneously and side by side. When the drill rods roll into the accommodating grooves of the bracket, the lifting group drives the bracket to rise, once the limiting baffle contacts the limiting baffle, the secondary splicing plate stops rising, and the main splicing plate continues to rise under the driving of the lifting group, so that the two drill rods are separated.

[0008] Further, the lifting group is bolted with the supporting frame through a Y-shaped connecting plate, the two ends of the Y-shaped connecting plate are aligned with the two ends of the cross section of the bracket, the limiting baffles comprise two, and the two limiting baffles are respectively transversely arranged at the two ends of the Y-shaped connecting plate. The two limiting baffles provide synchronous mechanical limiting for the limiting baffles on both sides of the secondary splicing plate, so that the two ends of the secondary splicing plate are balanced in the rising process. When the output shaft of the lifting group is at the lowest point, the main splicing plate and the secondary splicing plate form a complete whole, in the process of driving the main splicing plate to rise by the output shaft of the lifting group, the secondary splicing plate is stopped from rising, the first elastic component is compressed, the main splicing plate and the secondary splicing plate are gradually separated, and two independent accommodating grooves are formed. The accommodating groove on the main splicing plate can form effective limiting support for the drill rod at the bottom of the angle of the V-shaped frame plate. The secondary splicing plate can form effective angle support between the secondary splicing plate and the side wall of the main splicing plate.

[0009] Further, the secondary splicing plate is arranged at one end close to the storage rack, and the limiting baffles are arranged at the bottom end of the outer side wall of the secondary splicing plate. When the output shaft of the lifting group is at the lowest point, the top of the bracket is parallel to the plane where the storage rack is located, so that the drill rods on the storage rack can be smoothly introduced into the accommodating grooves of the bracket. When the bracket rises to a certain height, that is, the height area where the mechanical arm is convenient to clamp, the secondary splicing plate is stopped from rising, the main splicing plate continues to rise, until the main splicing plate and the secondary splicing plate form a certain height difference, the mechanical arm is convenient to clamp the two drill rods respectively, and the output shaft of the lifting group stops lifting. When the secondary splicing plate is stopped from rising, the bottom of the secondary splicing plate is not higher than the plane where the storage rack is located, so that the outer wall of the secondary splicing plate can limit the drill rods on the storage rack, and the drill rods are prevented from falling.

[0010] Further, two groups of separation components are symmetrically arranged on the storage rack, the separation components are arranged parallel to the plane of the storage rack, and the axis of the separation components is perpendicular to the axis of the drill pipe in the placement state. The separation components are used to separate the multiple drill pipes on the storage rack during rolling, which not only prevents the inclination or jam caused by the different rolling steps of the drill pipes due to the dense stacking on the inclined table, but also reduces the mutual collision of the drill pipes in the rolling process due to potential energy and the huge impact force caused by the superposition of kinetic energy by establishing a physical interval in advance.

[0011] Further, the separation component comprises a tubular member, an insert, and mutually cooperating inclined blocks. The tubular member is a hollow structure, the insert is adapted to be inserted into the tubular member, the inclined blocks comprise a first inclined block and a second inclined block, the first inclined block is arranged on the output shaft of the lifting group, the second inclined block is arranged at one end of the insert, the inclined surfaces of the first inclined block and the second inclined block are oppositely arranged, and the end of the insert away from the second inclined block is further provided with a spring. When the output shaft of the lifting group moves up and down, the first inclined block fixed on the output shaft moves, pushes the second inclined block to move laterally through the inclined surface, and further drives the insert to reciprocate in the tubular member. The top surface of the tubular member is parallel to the plane on which the storage rack is arranged.

[0012] Further, the top surface of the tubular member is arranged with a plurality of through holes at equal intervals along the axis, the through holes are provided with retractable plug bodies, the retractable plug bodies are installed on the through holes by a second elastic component, the top surface of the insert is provided with a plurality of protrusions, the bottom of the retractable plug body is an arc surface structure, the protrusions are in movable abutment with the arc surface structure of the retractable plug body, and the distance between the plurality of protrusions is twice the distance between the through holes. When the insert moves in the tubular member under the drive of the inclined block, the protrusions on the top surface of the insert will push the arc surface at the bottom of the retractable plug body. The distance between two adjacent retractable plug bodies corresponds to the one-way moving stroke of the output shaft of the lifting group. That is, when the bracket rises, the multiple retractable plug bodies will be pushed out, when the bracket descends, the retractable plug bodies that were pushed out will retract, and the multiple retractable plug bodies that were originally in the tubular member will be pushed out. Since the distance between the protrusions is twice the distance between the through holes, it means that every time the insert moves one cycle, half the number of retractable plug bodies will be pushed out, so that the protrusions of the retractable plug bodies form a blocking point on the surface of the tubular member. The retractable plug bodies are arranged in the arrangement direction of the multiple drill pipes, and can gradually release the drill pipes when the bracket moves periodically, so that the drill pipes move to the end of the storage rack gradually at a low speed.

[0013] Further, the main splicing plate is provided with a limiting block, the auxiliary splicing plate is provided with a limiting slot for inserting the limiting block, the first elastic component is arranged in the limiting slot, the upper end of the first elastic component is fixedly connected with the top end of the limiting slot, and the lower end of the first elastic component is fixedly connected with the top surface of the limiting block. When the first elastic component is compressed, the main splicing plate and the auxiliary splicing plate are separated in the vertical direction, after the main splicing plate falls back, the auxiliary splicing plate loses the blocking of external force, the first elastic component restores elastic deformation, so that the main splicing plate and the auxiliary splicing plate are flush, and new drill pipes can be carried.

[0014] Further, the opposite sides of the main splicing plate and the auxiliary splicing plate are respectively provided with mutually matched clamping components, and the distance between the top end of the auxiliary splicing plate and the main splicing plate is not less than the radius of the drill pipe. The clamping components enable the main splicing plate and the auxiliary splicing plate to be connected in sliding mode and cannot be separated and fallen off, so that a deformable overall structure is formed. When the main splicing plate and the auxiliary splicing plate are in the separated state, the auxiliary splicing plate can still provide sufficient containing angle and supporting area for the drill pipe between the side wall of the main splicing plate and the auxiliary splicing plate, so that the drill pipe can be stably lifted and cannot slide down, and necessary conditions for the grabbing of the mechanical arm are created.

[0015] Further, the support frame is provided with a bearing seat, the bottom surface of the storage rack is provided with two connecting blocks in the transverse direction, the middle parts of the two connecting blocks are provided with rotating shafts, and the rotating shafts are rotationally arranged in the shaft holes of the bearing seat. The storage rack can be used for storing or conveying drill pipes. After the drill pipes are sent to the storage rack by engineering equipment, the drill pipes are arranged in an orderly manner on the supporting rollers of the storage rack, and the side columns on the two sides of the storage rack are used for blocking the drill pipes to prevent the drill pipes from falling off. The storage rack can be rotated through the rotating shafts at the bottom and the bearing seat of the support frame, so that the height of one side of the storage rack is changed, the drill pipes are guided to roll to the other side, and the effect of conveying the drill pipes is achieved.

[0016] Further, the end of the support frame away from the bracket is provided with a gas cylinder, the gas cylinder includes two, the two gas cylinders are symmetrically arranged on the support frame, and the movable end bottom of the storage rack is connected with the output shaft of the gas cylinder. The symmetrical driving of the two gas cylinders ensures that the lifting force is uniformly applied to the movable end bottom of the storage rack. By controlling the synchronous extension and contraction of the gas cylinder, the inclination angle of the storage rack can be accurately adjusted, so that the speed and timing of the drill pipes rolling to the bracket by gravity are controlled.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. The present application realizes the function of simultaneously separating and preparing two drill pipes through single lifting action by arranging the separable bracket composed of the main splicing plate, the auxiliary splicing plate and the first elastic component, and cooperating with the limiting baffle and the limiting baffle strip, so that the waiting time of the equipment in the idle stroke is significantly reduced, and the conveying efficiency and energy utilization rate are greatly improved.

[0019] 2、The present application realizes dynamic separation and buffering in the process of rolling down the drill pipe by setting the telescopic separation assembly driven by the lifting group and connected through the inclined block, separates the drill pipes in sequence, avoids the collision between the drill pipes caused by gravity acceleration, effectively protects the drill pipe thread and surface coating, and improves the operation safety and equipment life;

[0020] 3、The present application constructs an efficient pipe feeding system by integrally and cooperatively designing the adjustable-inclination storage rack, the separable bracket and the dynamic separation assembly, the actions of all components are driven by the main shaft of the lifting group, the linkage is strong, the automation and synchronization of the pipe feeding, separation, lifting and separation processes are realized, and the impact and jamming risk is significantly reduced.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below combined with examples and drawings, the illustrative implementation mode of the present application and its description are only used to explain the present application, and do not limit the present application.

[0029] Example one, as Figures 1-6The drill pipe storage platform and pipe feeding device disclosed by the application comprises a storage rack 2 for placing drill pipes 1, a support frame 3 arranged at the bottom of the storage rack 2, a lifting group 4 and a bracket 5, the end of the storage rack 2 is rotatably arranged on the support frame 3, the lifting group 4 is arranged below the bracket 5 and connected with the bracket 5, and a containing groove for transversely placing the drill pipes 1 is arranged at the top end of the bracket 5.

[0030] The bracket 5 comprises a positioning horizontal plate 6 and a V-shaped frame plate 7, a vertical cutting line is arranged on one side of the V-shaped frame plate 7 along the middle axis, the V-shaped frame plate 7 is cut into a main splicing plate 701 and a secondary splicing plate 702 by the cutting line, the main splicing plate 701 and the secondary splicing plate 702 are slidably connected through a first elastic component 8, the main splicing plate 701 is arranged at the two ends of the positioning horizontal plate 6, the bottom of the positioning horizontal plate 6 is fixedly connected with the output shaft of the lifting group 4, the outer side wall of the secondary splicing plate 702 is provided with a limiting baffle 9, and a limiting baffle 10 for blocking the rising of the limiting baffle 9 is arranged on the shell of the lifting group 4. Specifically, the V-shaped frame plate 7 can be separated, so that the bracket 5 becomes a composite body that can be dynamically separated, and the containing groove can simultaneously contain two drill pipes 1 side by side. When the drill pipes 1 roll into the containing groove of the bracket 5, the lifting group 4 drives the bracket 5 to rise, once the limiting baffle 9 contacts the limiting baffle 10, the secondary splicing plate 702 stops rising, and the main splicing plate 701 continues to rise under the driving of the lifting group 4, so that the two drill pipes 1 are separated. For the structure provided with only the bracket 5, the mechanical arm is still inconvenient for grabbing the two drill pipes 1 in contact side by side, which increases the operation difficulty and the risk of damaging the surface coating of the drill pipes 1.

[0031] The lifting group 4 is bolted with the support frame 3 through a Y-shaped connecting plate 11, the two ends of the Y-shaped connecting plate 11 are aligned with the two ends of the cross section of the bracket 5, the limiting baffles 10 comprise two, and the two limiting baffles 10 are horizontally arranged at the two ends of the Y-shaped connecting plate 11. Specifically, the two limiting baffles 10 provide synchronous mechanical limiting for the limiting baffles 9 on the two sides of the secondary splicing plate 702, so that the two ends of the secondary splicing plate 702 are balanced in the rising process. When the output shaft of the lifting group 4 is at the lowest point, the main splicing plate 701 and the secondary splicing plate 702 form a complete whole, in the process of driving the main splicing plate 701 to rise by the output shaft of the lifting group 4, the secondary splicing plate 702 is blocked and stops rising, the first elastic component 8 is compressed, and the main splicing plate 701 and the secondary splicing plate 702 gradually separate to form two independent containing grooves. The containing groove on the main splicing plate 701 can form effective limiting support for the drill pipes 1 at the bottom angle of the V-shaped frame plate 7. The secondary splicing plate 702 can form effective angle support between the secondary splicing plate 702 and the side wall of the main splicing plate 701.

[0032] The sub-splicing plate 702 is arranged near one end of the storage rack 2, and the limiting baffle 9 is arranged at the bottom end of the outer wall of the sub-splicing plate 702. Specifically, when the output shaft of the lifting group 4 is at the lowest point, the top of the bracket 5 is parallel to the plane where the storage rack 2 is located, so that the drill pipe 1 on the storage rack 2 can be smoothly introduced into the accommodating groove of the bracket 5. When the bracket 5 rises to a certain height, that is, the height area where the mechanical arm is convenient to clamp, the sub-splicing plate 702 is stopped from rising due to obstruction, the main-splicing plate 701 continues to rise, until the main-splicing plate 701 and the sub-splicing plate 702 form a certain height difference, which is convenient for the mechanical arm to clamp the two drill pipes 1 respectively, and the output shaft of the lifting group 4 stops lifting. When the sub-splicing plate 702 is stopped from rising due to obstruction, the bottom of the sub-splicing plate 702 is not higher than the plane where the storage rack 2 is located, so that it can be ensured that the outer wall of the sub-splicing plate 702 limits the drill pipe 1 located on the storage rack 2, avoiding the drill pipe 1 from falling.

[0033] The storage rack 2 is symmetrically provided with two groups of separation assemblies, the separation assemblies are arranged parallel to the plane of the storage rack 2, and the axis of the separation assembly is perpendicular to the axis of the drill pipe 1 in the placement state. Specifically, the separation assembly is used to separate the plurality of drill pipes 1 on the storage rack 2 during rolling, which not only can prevent the drill pipes 1 from rolling out of synchronization due to dense stacking on the inclined table top, causing tilting or jamming, but also can reduce the mutual collision of the drill pipes 1 due to potential energy during rolling, and the huge impact force generated by the superposition of kinetic energy.

[0034] The separation assembly comprises a tubular member 12, an insert 13 and mutually cooperating inclined blocks. The tubular member 12 is a hollow structure, the insert 13 is adapted to be inserted into the tubular member 12, and the inclined blocks comprise a first inclined block 14 and a second inclined block 15. The first inclined block 14 is arranged on the output shaft of the lifting group 4, and the second inclined block 15 is arranged at one end of the insert 13. The inclined surfaces of the first inclined block 14 and the second inclined block 15 are oppositely arranged, and the end of the insert 13 away from the second inclined block 15 is further provided with a spring. Specifically, when the output shaft of the lifting group 4 moves up and down, the first inclined block 14 fixed on the output shaft moves along with it, pushes the second inclined block 15 to move laterally through the inclined surface, and drives the insert 13 to reciprocate in the tubular member 12 in the deformation process of the spring. This design can synchronously drive without additional independent power supply and control unit, thereby reducing cost and energy consumption, and further improving the synergistic effect. The top surface of the tubular member 12 is parallel to the plane where the storage rack 2 is located.

[0035] The top surface of the tubular member 12 is provided with a plurality of through holes 16 arranged equidistantly along the axis, and the through holes 16 are provided with retractable plug bodies 17, the retractable plug bodies 17 are installed on the through holes 16 through the second elastic components 18, the top surface of the insert 13 is provided with a plurality of protrusions 19, the bottom of the retractable plug body 17 is arc-shaped structure, the protrusions 19 and the arc-shaped structure of the retractable plug body 17 are in movable abutment, and the spacing of the plurality of protrusions 19 is twice the spacing of the plurality of through holes 16. Specifically, when the insert 13 moves in the tubular member 12 under the driving of the inclined block, the protrusions 19 on the top surface of the insert 13 will push the arc surface at the bottom of the retractable plug body 17. The distance between two adjacent retractable plug bodies 17 corresponds to the one-way movement stroke of the output shaft of the lifting group 4. That is, when the carrier 5 rises, the plurality of retractable plug bodies 17 are pushed out, and when the carrier 5 descends, the retractable plug bodies 17 that were pushed out are retracted, and the plurality of retractable plug bodies 17 that were originally in the tubular member 12 are pushed out. Since the spacing of the protrusions 19 is twice the spacing of the through holes 16, this means that for each movement cycle of the insert 13, half the number of retractable plug bodies 17 will be pushed out, so that the protrusions 19 on the surface of the tubular member 12 form a blocking point, that is, the distance between three retractable plug bodies 17 corresponds to the spacing between two protrusions 19. The retractable plug bodies 17 are arranged in the direction of the plurality of drill rods 1 and are blocked at intervals, so that the drill rods 1 can be gradually released when the carrier 5 moves periodically, so that the drill rods 1 move to the end of the storage rack 2 at low speed.

[0036] The main splicing plate 701 is provided with a limiting block 20, the auxiliary splicing plate 702 is provided with a limiting groove 21 for inserting the limiting block 20, the first elastic component 8 is arranged in the limiting groove 21, the upper end of the first elastic component 8 is fixedly connected with the top end of the limiting groove 21, and the lower end of the first elastic component 8 is fixedly connected with the top surface of the limiting block 20. Specifically, when the first elastic component 8 is compressed, the main splicing plate 701 and the auxiliary splicing plate 702 are separated in the vertical direction, after the main splicing plate 701 falls back, the auxiliary splicing plate 702 loses the blocking of the external force, the first elastic component 8 restores the elastic deformation, so that the main splicing plate 701 and the auxiliary splicing plate 702 are flush, and are used for carrying new drill rods 1.

[0037] The opposite sides of the main splice plate 701 and the auxiliary splice plate 702 are respectively provided with mutually matched clamping assemblies, and the top end of the auxiliary splice plate 702 is at a distance from the main splice plate 701 which is not less than the radius of the drill rod 1. Specifically, the clamping assemblies make the main splice plate 701 and the auxiliary splice plate 702 in sliding connection and cannot be separated and fallen off, so that they form a deformable whole. Preferably, the clamping assemblies include C-shaped grooves arranged on the side walls of the main splice plate 701 and T-shaped grooves arranged on the auxiliary splice plate 702, and the C-shaped grooves and the T-shaped grooves are clamped. When the main splice plate 701 and the auxiliary splice plate 702 are in a separated state, the auxiliary splice plate 702 and the side walls of the main splice plate 701 can still provide sufficient containing angle and support area for the drill rod 1 thereon, so as to ensure that the drill rod 1 is stably lifted and cannot slide down, and necessary conditions are created for the grabbing of the mechanical arm.

[0038] The support frame 3 is provided with a bearing seat, the bottom surface of the storage rack 2 is provided with a connecting block at both ends in the transverse direction, the middle part of the two connecting blocks is provided with a rotating shaft, and the rotating shaft is rotationally arranged in the shaft hole of the bearing seat. Specifically, the storage rack 2 can be used to store or transport the drill rod 1. After the drill rod 1 is sent to the storage rack 2 by engineering equipment, the drill rod 1 will be arranged in order on the supporting rollers of the storage rack 2. The side columns on both sides of the storage rack 2 are used to block the drill rod 1 to prevent it from falling off. The storage rack 2 can be rotated through the rotating shaft at the bottom and the bearing seat of the support frame 3, so as to change the height of one side of the storage rack 2, and then make the drill rod 1 roll to the other side and realize the effect of rod feeding.

[0039] The end of the support frame 3 away from the bracket 5 is provided with a gas cylinder 22, the gas cylinder 22 includes two, the two gas cylinders 22 are symmetrically arranged on the support frame 3, and the movable end bottom of the storage rack 2 is connected with the output shaft of the gas cylinder 22. Specifically, the symmetrical driving of the double gas cylinders ensures that the lifting force is uniformly applied to the movable end bottom of the storage rack 2. By controlling the synchronous extension and contraction of the gas cylinder 22, the inclination angle of the storage rack 2 can be accurately adjusted, so as to control the speed and timing of the drill rod 1 rolling to the bracket 5 by gravity.

[0040] In the embodiment one, the specific working principle of the drill rod storage platform and the rod feeding device is provided.

[0041] The control system commands two cylinders 22 to operate synchronously, lifting the movable end of the storage rack 2, causing the storage rack 2 to rotate around its end shaft, forming an inclined slope towards the bracket 5. Several drill rods 1 are fed onto the storage rack 2 by the engineering equipment. Under the action of gravity, the drill rods 1 begin to roll along the inclined storage rack 2 towards the bracket 5 at the end. When the telescopic plug 17 retracts into the tubular component 12, its top surface is flush with the plane containing the through hole 16. During the rolling process, the drill rods 1 fall sequentially between several telescopic plugs 17. The telescopic plugs 17 physically separate the drill rod 1 queue, allowing the drill rods 1 to pass sequentially. This continues until the first two drill rods 1 smoothly roll into the receiving groove of the lowest bracket 5 and are supported side-by-side. After the drill rods 1 are in place, the lifting group 4 is activated, and its output shaft begins to move upward. As the output shaft of the lifting group 4 rises, the main splicing plate 701 rises, causing the entire bracket 5 to rise accordingly. When the sub-assembly plate 702 rises to the predetermined height, the limiting baffle 9 on the outer wall of the sub-assembly plate 702 contacts the limiting baffle 10 fixed on the Y-shaped connecting plate 11, preventing the sub-assembly plate 702 from rising further. The output shaft of the lifting group 4 continues to rise, separating the two drill rods 1. The separation action causes the two drill rods 1, which were originally placed side by side, to be lifted separately, creating a significant height difference between the two drill rods 1, making it easier for the robotic arm to grasp them separately.

[0042] After the gripping is completed, the output shaft of the lifting group 4 descends, causing the first inclined block 14 to move downwards. This movement, via the inclined plane, moves the second inclined block 15 and the insert 13. This movement changes the position of the protrusion 19 on the top of the insert 13. The previously lifted telescopic plug 17 retracts under the action of the second elastic component 18, while the corresponding telescopic plug 17 in the next group is pushed out by the new protrusion 19, updating the separation position and allowing subsequent drill rods 1 to proceed. Through cyclical operation, the drill rods 1 are sequentially released and advanced, ensuring the gripping operation is performed sequentially.

[0043] Example 3: Based on Example 1, this example proposes an optimized structure for a drill pipe storage platform and a pipe feeding device.

[0044] Both the first inclined block 14 and the second inclined block 15 are replaced with triangular structures, so that the output shaft of the lifting group 4 can drive the movement of the insert 13 in any single direction. That is, when the output shaft of the lifting group 4 moves upward, the insert 13 moves to the right, and when the output shaft of the lifting group 4 moves downward, the insert 13 moves to the left.

[0045] In addition, at least two points at the end of the tubular member 12 are not provided with telescopic plugs 17, thereby ensuring that at least two drill rods 1 on the storage rack 2 move to the end of the storage rack 2, so as to be simultaneously introduced into the bracket 5.

[0046] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, and these corresponding changes and modifications shall all belong to the protection scope of the claims of the present application.
