Description

Technical Field

[0001] This invention relates to the field of drill pipe conveying technology, and in particular to a drill pipe storage platform and a pipe conveying device. Background Technology

[0002] Drill pipe is an indispensable key tool in oil and gas drilling, geological exploration, and other construction processes. Due to the large drilling depths and the large number of drill pipes required, coupled with the significant weight and length of each individual pipe, the safe and efficient storage and sequential supply of drill pipes within the limited space of the well site becomes a crucial factor affecting operational efficiency. To facilitate the storage and retrieval of drill pipes, existing technologies often employ a support-type drill pipe storage platform with an inclined platform. During operation, multiple drill pipes are transported to the platform via a conveyor system, where they roll downwards along the inclined surface under their own weight, converging at the retrieval end. To facilitate gripping by the robotic arm, a separate lifting device is typically installed at the lower inclined end of the platform to raise the bottom drill pipe to a certain height, separating it from adjacent drill pipes and preventing interference or collisions during clamping.

[0003] However, existing drill pipe storage and delivery methods still have shortcomings. First, the delivery process is sequential; after the robotic arm removes a drill pipe, the lifting device needs to reset to receive a new drill pipe and lift it before the next delivery can begin. This intermittent operation results in idle waiting time, especially when multiple drill pipes need to be retrieved consecutively, leading to long cycle times and low efficiency. Second, the drill pipe relies entirely on gravity to accelerate its descent on the inclined platform, resulting in high impact force at the end. This not only generates significant noise but also increases the risk of rigid collisions with adjacent drill pipes or platform baffles, potentially damaging the threaded joints or surface anti-corrosion coating and shortening the drill pipe's lifespan. Furthermore, excessive sliding potential energy can cause the drill pipe to tilt or jam due to asynchronous rolling, leading to delivery failure. Additionally, the lack of effective coordinated control between the lifting device, platform, and clamping mechanism results in low motion correlation, high system energy consumption, and insufficient intelligence, failing to meet the requirements of modern drilling operations for automation, high efficiency, and high safety. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a drill pipe storage platform and a drill pipe feeding device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drill pipe storage platform and a rod delivery device include a storage rack for placing drill pipes, a support frame disposed at the bottom of the storage rack, a lifting assembly and a bracket. The end of the storage rack is rotatably mounted on the support frame, the lifting assembly is disposed below the bracket and connected to the bracket, and the top of the bracket is provided with a receiving groove for horizontally placing drill pipes. The bracket includes a positioning horizontal plate and a V-shaped frame plate. The V-shaped frame plate has a vertical cutting line on one side of its central axis, dividing it into a main splicing plate and a secondary splicing plate. The main splicing plate and the secondary splicing plate are slidably connected by a first elastic component. The main splicing plate is located at both ends of the positioning horizontal plate, and the bottom of the positioning horizontal plate is fixedly connected to the output shaft of the lifting assembly. A limit baffle is provided on the outer wall of the secondary splicing plate, and a limit strip is provided on the housing of the lifting assembly to prevent the limit baffle from rising. The separable V-shaped frame plate makes the bracket a dynamically separable composite, and the receiving slot can simultaneously accommodate two drill rods side-by-side. When the drill rod rolls into the receiving slot of the bracket, the lifting assembly drives the bracket to rise. Once the limit baffle contacts the limit strip, the secondary splicing plate stops rising, while the main splicing plate continues to rise under the action of the lifting assembly, causing the two drill rods to separate.

[0006] Furthermore, the lifting assembly is bolted to the support frame via a Y-shaped connecting plate. The two ends of the Y-shaped connecting plate are aligned with the two ends of the bracket's cross-section. Two limiting strips are provided, each horizontally installed at one end of the Y-shaped connecting plate. These two limiting strips provide synchronized mechanical limiting for the limiting strips on both sides of the sub-splicing plate, ensuring balanced force at both ends of the sub-splicing plate during its ascent. When the output shaft of the lifting assembly is at its lowest point, the main splicing plate and the sub-splicing plate form a complete unit. As the output shaft of the lifting assembly drives the main splicing plate upward, the sub-splicing plate is obstructed and stops rising. The first elastic component compresses, and the main splicing plate and the sub-splicing plate gradually separate, forming two independent receiving grooves. The receiving groove on the main splicing plate provides effective limiting support for the drill rod at the bottom angle of the V-shaped frame plate. The sub-splicing plate provides effective angular support between the side walls of the sub-splicing plate and the main splicing plate.

[0007] Furthermore, the secondary splicing plate is positioned near one end of the storage rack, and the limiting baffle is located at the bottom of the outer wall of the secondary splicing plate. When the output shaft of the lifting assembly is at its lowest point, the top of the bracket is parallel to the plane of the storage rack, allowing the drill rods on the storage rack to be smoothly guided into the receiving slot of the bracket. When the bracket rises to a certain height, i.e., a height range easily accessible for the robotic arm to grip, the secondary splicing plate is obstructed and stops rising, while the main splicing plate continues to rise until a certain height difference is formed between the main and secondary splicing plates, facilitating the robotic arm to grip the two drill rods separately, at which point the output shaft of the lifting assembly stops rising. When the secondary splicing plate stops rising due to obstruction, the bottom of the secondary splicing plate is not higher than the plane of the storage rack, ensuring that the outer wall of the secondary splicing plate limits the drill rods located on the storage rack, preventing the drill rods from falling off.

[0008] Furthermore, two sets of separating components are symmetrically arranged on the storage rack. These separating components are parallel to the plane of the storage rack, and their axes are perpendicular to the axis of the drill rods in their placed state. The separating components are used to separate multiple drill rods on the storage rack during rolling. This not only prevents tilting or jamming caused by asynchronous rolling due to dense accumulation of drill rods on the inclined platform, but also reduces the mutual collisions of drill rods due to potential energy during rolling, as well as the enormous impact force generated by the superposition of kinetic energy, by pre-establishing physical intervals.

[0009] Furthermore, the separating assembly includes a tubular member, an insert, and cooperating inclined blocks. The tubular member has a hollow structure, and the insert is fitted into the tubular member. The inclined blocks include a first inclined block and a second inclined block. The first inclined block is disposed on the output shaft of the lifting assembly, and the second inclined block is disposed at one end of the insert. The inclined surfaces of the first and second inclined blocks are opposite to each other. A spring is also provided at the end of the insert away from the second inclined block. When the output shaft of the lifting assembly moves up and down, the first inclined block fixed to its output shaft moves accordingly, pushing the second inclined block to move laterally through the inclined surface, thereby causing the insert to reciprocate within the tubular member. The top surface of the tubular member is parallel to the plane of the storage rack.

[0010] Furthermore, the top surface of the tubular component has several through holes evenly spaced along the axis. Telescopic plugs are installed in these through holes via a second elastic component. The top surface of the insert has several protrusions, and the bottom of the telescopic plugs is an arc-shaped structure. The protrusions movably abut against the arc-shaped structure of the telescopic plugs. The spacing between the protrusions is twice the spacing between the through holes. When the insert moves within the tubular component under the drive of the inclined block, the protrusions on its top surface push against the arc-shaped bottom of the telescopic plugs. The distance between two adjacent telescopic plugs corresponds to the unidirectional travel of the output shaft of the lifting assembly. That is, when the bracket rises, multiple telescopic plugs at intervals are pushed out; when the bracket descends, the originally pushed-out telescopic plugs retract, and multiple telescopic plugs originally positioned within the tubular component are pushed out. Since the spacing between the protrusions is twice the spacing between the through holes, this means that for each cycle of movement, the insert will periodically push up half of the telescopic plugs, causing them to protrude from the surface of the tubular component and form blocking points. The telescopic plugs provide intermittent blocking along the arrangement of multiple drill rods, allowing the drill rods to be gradually released during the periodic movement of the support, enabling the drill rods to move gradually towards the end of the storage rack at low speed.

[0011] Furthermore, the main splicing plate is provided with a limiting block, and the secondary splicing plate is provided with a limiting groove for the limiting block to be inserted. The first elastic component is disposed in the limiting groove, with its upper end fixedly connected to the top of the limiting groove and its lower end fixedly connected to the top surface of the limiting block. When the first elastic component is compressed, the main splicing plate and the secondary splicing plate separate in the vertical direction. After the main splicing plate falls back, the secondary splicing plate loses the resistance of the external force, and the first elastic component restores its elastic deformation, making the main splicing plate and the secondary splicing plate flush, for supporting new drill rods.

[0012] Furthermore, the main splicing plate and the sub-splicing plate are respectively provided with mutually cooperating snap-fit ​​components on their opposing sides. The distance between the top end of the sub-splicing plate and the main splicing plate is not less than the radius of the drill rod. The snap-fit ​​components allow the main splicing plate and the sub-splicing plate to slide together without separating or falling off, forming a deformable integral structure. When the main splicing plate and the sub-splicing plate are in a separated state, the sidewalls of the sub-splicing plate and the main splicing plate can still provide sufficient containment angle and support area for the drill rod, ensuring that the drill rod is stably supported and will not slip, creating the necessary conditions for the robotic arm to grasp it.

[0013] Furthermore, the support frame is equipped with a bearing seat, and the bottom surface of the storage rack has connecting blocks at both ends in the lateral direction. A rotating shaft is located in the middle of the two connecting blocks, and the rotating shaft is rotatably mounted in the shaft hole of the bearing seat. The storage rack can be used to store or transport drill rods. After the drill rods are fed onto the storage rack by engineering equipment, they will be neatly arranged on the support rollers of the storage rack. The side rails on both sides of the storage rack are used to prevent the drill rods from falling. The storage rack can rotate through the rotating shaft at the bottom and the bearing seat of the support frame, thereby changing the height of one side of the storage rack, so that the drill rods can be rolled and guided to the other side, achieving the effect of feeding the drill rods.

[0014] Furthermore, a cylinder is provided at the end of the support frame away from the bracket. Two cylinders are symmetrically arranged on the support frame, and the bottom of the movable end of the storage rack is connected to the output shaft of the cylinder. The symmetrical dual-cylinder drive ensures that the lifting force is evenly applied to the bottom of the movable end of the storage rack. By controlling the synchronous extension and retraction of the cylinders, the tilt angle of the storage rack can be precisely adjusted, thereby controlling the speed and timing of the drill rod rolling towards the bracket under gravity.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting a separable bracket consisting of a main splicing plate, a secondary splicing plate and a first elastic component, and in conjunction with a limiting baffle and a limiting stop bar, achieves the function of simultaneously separating and preparing two drill rods in a single lifting action. This not only significantly reduces the equipment idle waiting time, but also greatly improves the rod delivery efficiency and energy utilization rate. 2. This invention achieves dynamic separation and buffering during the drill rod rolling process by setting up a telescopic separation component driven by the lifting group and linked by the inclined blocks. It separates the drill rods one by one, which can avoid collisions between drill rods caused by gravity acceleration, effectively protect the drill rod threads and surface coating, and improve operational safety and equipment life. 3. This invention integrates the adjustable tilt storage rack, detachable bracket, and dynamic separation component into a cohesive design, creating a highly efficient rod feeding system. The actions of each component are driven by the lifting assembly spindle, resulting in strong linkage and automation and synchronization of the rod feeding, separation, lifting, and separation processes, significantly reducing the risk of impact and jamming.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0018] Example 1, as Figures 1-6 As shown, the present invention discloses a drill pipe storage platform and a rod delivery device, including a storage rack 2 for placing drill pipe 1, and a support frame 3 disposed at the bottom of the storage rack 2, and also includes a lifting assembly 4 and a bracket 5. The end of the storage rack 2 is rotatably mounted on the support frame 3, the lifting assembly 4 is disposed below the bracket 5 and connected to the bracket 5, and the top of the bracket 5 is provided with a receiving groove for horizontally placing the drill pipe 1.

[0019] The bracket 5 includes a positioning horizontal plate 6 and a V-shaped frame plate 7. The V-shaped frame plate 7 has a vertical cutting line on one side of its central axis, dividing it into a main splicing plate 701 and a secondary splicing plate 702. The main splicing plate 701 and the secondary splicing plate 702 are slidably connected by a first elastic component 8. The main splicing plate 701 is located at both ends of the positioning horizontal plate 6. The bottom of the positioning horizontal plate 6 is fixedly connected to the output shaft of the lifting assembly 4. A limit baffle 9 is provided on the outer wall of the secondary splicing plate 702. A limit strip 10 is provided on the housing of the lifting assembly 4 to prevent the limit baffle 9 from rising. Specifically, the separable V-shaped frame plate 7 makes the bracket 5 a dynamically separable composite, and the receiving slot can simultaneously accommodate two drill rods 1 side-by-side. When drill rod 1 rolls into the receiving groove of bracket 5, lifting assembly 4 drives bracket 5 to rise. Once limit baffle 9 contacts limit stop 10, sub-splicing plate 702 stops rising, while main splicing plate 701 continues to rise under the drive of lifting assembly 4, causing the two drill rods 1 to separate. However, for structures with only bracket 5, it is still inconvenient for the robotic arm to grasp the two drill rods 1 that are in contact side by side, increasing the difficulty of operation and the risk of damaging the surface coating of drill rod 1.

[0020] The lifting assembly 4 is bolted to the support frame 3 via 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. Two limiting bars 10 are installed laterally at both ends of the Y-shaped connecting plate 11. Specifically, the two limiting bars 10 provide synchronous mechanical limiting for the limiting bars 9 on both sides of the sub-splicing plate 702, ensuring that the sub-splicing plate 702 is balanced in force during its ascent. When the output shaft of the lifting assembly 4 is at its lowest point, the main splicing plate 701 and the sub-splicing plate 702 form a complete unit. During the ascent of the main splicing plate 701 driven by the output shaft of the lifting assembly 4, the sub-splicing plate 702 is blocked and stops rising. The first elastic component 8 is compressed, and the main splicing plate 701 and the sub-splicing plate 702 gradually separate, forming two independent receiving slots. The receiving slots on the main splicing plate 701 can effectively limit and support the drill rod 1 at the bottom angle of the V-shaped frame plate 7. The sub-segmentation plate 702 can form an effective angular support between the sidewalls of the sub-segmentation plate 702 and the main splicing plate 701.

[0021] The secondary splicing plate 702 is positioned near one end of the storage rack 2, and the limiting baffle 9 is located at the bottom of the outer wall of the secondary splicing plate 702. Specifically, when the output shaft of the lifting group 4 is at its lowest point, the top of the bracket 5 is parallel to the plane of the storage rack 2, allowing the drill rod 1 on the storage rack 2 to be smoothly guided into the receiving slot of the bracket 5. When the bracket 5 rises to a certain height, i.e., a height range that the robotic arm can easily grip, the secondary splicing plate 702 is blocked and stops rising, while the main splicing plate 701 continues to rise until a certain height difference is formed between the main splicing plate 701 and the secondary splicing plate 702, facilitating the robotic arm to grip the two drill rods 1 respectively, and the output shaft of the lifting group 4 stops rising. When the secondary splicing plate 702 is blocked and stops rising, the bottom of the secondary splicing plate 702 is not higher than the plane of the storage rack 2, ensuring that the outer wall of the secondary splicing plate 702 limits the drill rod 1 located on the storage rack 2, preventing the drill rod 1 from falling.

[0022] Two sets of separating components are symmetrically arranged on the storage rack 2. The separating components are parallel to the plane of the storage rack 2, and the axis of the separating components is perpendicular to the axis of the drill rod 1 in its placed state. Specifically, the separating components are used to separate the multiple drill rods 1 on the storage rack 2 during rolling. This not only prevents the drill rods 1 from tilting or getting stuck due to uneven rolling caused by dense accumulation on the inclined platform, but also reduces the mutual collision of the drill rods 1 due to potential energy during rolling, as well as the huge impact force generated by superimposed kinetic energy, by pre-establishing physical intervals.

[0023] The separating assembly includes a tubular member 12, an insert 13, and cooperating inclined blocks. The tubular member 12 has a hollow structure, and the insert 13 is fitted and inserted into the tubular member 12. The inclined blocks include a first inclined block 14 and a second inclined block 15. The first inclined block 14 is disposed on the output shaft of the lifting assembly 4, and the second inclined block 15 is disposed at one end of the insert 13. The inclined surfaces of the first inclined block 14 and the second inclined block 15 are arranged opposite each other. A spring is also disposed at the end of the insert 13 away from the second inclined block 15. Specifically, when the output shaft of the lifting assembly 4 moves up and down, the first inclined block 14, fixed to its output shaft, moves accordingly, pushing the second inclined block 15 to move laterally through the inclined surface. During the deformation of the spring, the insert 13 is driven to reciprocate within the tubular member 12. This design can be synchronously driven without an additional independent power supply and control unit, reducing costs 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.

[0024] The top surface of the tubular member 12 has a plurality of through holes 16 evenly spaced along the axis. Telescopic plugs 17 are provided on the through holes 16 and are mounted on the through holes 16 via a second elastic component 18. The top surface of the insert 13 has a plurality of protrusions 19. The bottom of the telescopic plug 17 has an arc-shaped structure, and the protrusions 19 movably abut against the arc-shaped structure of the telescopic plug 17. The spacing between the protrusions 19 is twice the spacing between the through holes 16. Specifically, when the insert 13 moves within the tubular member 12 under the drive of the inclined block, the protrusions 19 on its top surface push against the arc-shaped bottom surface of the telescopic plug 17. The distance between two adjacent telescopic plugs 17 corresponds to the unidirectional travel of the output shaft of the lifting assembly 4. That is, when the bracket 5 rises, multiple telescopic plugs 17 at intervals are pushed out; when the bracket 5 descends, the previously pushed-out telescopic plugs 17 retract, and multiple telescopic plugs 17 originally located within the tubular member 12 at intervals are pushed out. Since the spacing between the protrusions 19 is twice the spacing between the through holes 16, this means that for each cycle of movement of the insert 13, half of the telescopic plugs 17 will be pushed up at intervals, causing them to protrude from the surface of the tubular member 12 to form blocking points. That is, the distance between three telescopic plugs 17 corresponds to the spacing between two protrusions 19. The telescopic plugs 17 provide interval blocking along the arrangement direction of the multiple drill rods 1, allowing the drill rods 1 to be gradually released during the periodic movement of the bracket 5, so that the drill rods 1 gradually move towards the end of the storage rack 2 at low speed.

[0025] The main splicing plate 701 is provided with a limiting block 20, and the secondary splicing plate 702 is provided with a limiting groove 21 for the limiting block 20 to be inserted. The first elastic component 8 is disposed in the limiting groove 21, the upper end of the first elastic component 8 is fixedly connected to the top end of the limiting groove 21, and the lower end of the first elastic component 8 is fixedly connected to the top surface of the limiting block 20. Specifically, when the first elastic component 8 is compressed, the main splicing plate 701 and the secondary splicing plate 702 separate in the vertical direction. After the main splicing plate 701 falls back, the secondary splicing plate 702 loses the resistance of the external force, and the first elastic component 8 restores its elastic deformation, making the main splicing plate 701 and the secondary splicing plate 702 flush, for supporting the new drill rod 1.

[0026] The main splicing plate 701 and the secondary splicing plate 702 are respectively provided with mutually cooperating snap-fit ​​components on their opposing sides. The distance between the top end of the secondary splicing plate 702 and the main splicing plate 701 is not less than the radius of the drill rod 1. Specifically, the snap-fit ​​components allow the main splicing plate 701 and the secondary splicing plate 702 to slide together without separating or falling off, forming a deformable integral structure. Preferably, the snap-fit ​​components include a C-shaped groove provided on the side wall of the main splicing plate 701 and a T-shaped groove provided on the secondary splicing plate 702, with the C-shaped groove and the T-shaped groove snapping together. When the main splicing plate 701 and the secondary splicing plate 702 are in a separated state, the secondary splicing plate 702 and the side wall of the main splicing plate 701 can still provide sufficient containment angle and support area for the drill rod 1, ensuring that the drill rod 1 is stably supported and will not slip, creating the necessary conditions for the robotic arm to grasp it.

[0027] The support frame 3 is equipped with a bearing seat, and the storage rack 2 has connecting blocks at both ends of its bottom surface in the horizontal direction. A rotating shaft is located in the middle of the two connecting blocks and is rotatably mounted in the shaft hole of the bearing seat. Specifically, the storage rack 2 can be used to store or transport drill rods 1. After the drill rods 1 are fed onto the storage rack 2 by engineering equipment, they will be neatly arranged on the support rollers of the storage rack 2. The side rails on both sides of the storage rack 2 are used to prevent the drill rods 1 from falling. The storage rack 2 can be rotated by the rotating shaft at the bottom and the bearing seat of the support frame 3, thereby changing the height of one side of the storage rack 2, so that the drill rods 1 can be rolled and guided to the other side, achieving the effect of feeding the drill rods.

[0028] A cylinder 22 is provided at the end of the support frame 3 away from the bracket 5. Two cylinders 22 are symmetrically arranged on the support frame 3. The bottom of the movable end of the storage rack 2 is connected to the output shaft of the cylinder 22. Specifically, the symmetrical drive of the two cylinders ensures that the lifting force is evenly applied to the bottom of the movable end of the storage rack 2. By controlling the synchronous extension and retraction of the cylinders 22, the tilt angle of the storage rack 2 can be precisely adjusted, thereby controlling the speed and timing of the drill rod 1 rolling towards the bracket 5 under gravity.

[0029] Example 2, based on Example 1, presents a specific working principle of a drill pipe storage platform and a pipe feeding device.

[0030] 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.

[0031] 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.

[0032] Example 3: Based on Example 1, this example proposes an optimized structure for a drill pipe storage platform and a drill pipe feeding device.

[0033] 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.

[0034] 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 facilitate simultaneous introduction onto the bracket 5.

[0035] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
