Description

Technical Field

[0001] This invention relates to the technical field of storing and transporting drill pipes or tubing, and in particular to an intelligent storage box. Background Technology

[0002] Against the backdrop of large-scale development in the oil drilling and mining industries, the frequency of drilling operations continues to increase. As core consumable materials, drill pipe and tubing are experiencing a significant increase in usage and turnover. Consequently, the industry's requirements for the efficiency and safety of the entire process of packaging, transporting, storing, and disassembling drill pipe and tubing are constantly rising. Currently, the traditional drill pipe and tubing handling methods used in the industry still suffer from numerous problems such as cumbersome procedures, high labor costs, low operational efficiency, and poor protection, making them difficult to adapt to the development needs of modern drilling operations.

[0003] Currently, the standardized packaging method for drill pipes or tubing at the factory is hexagonal bundling. Drill pipe or tubing manufacturers use dedicated production lines to shape the drill pipes or tubing, then secure them with steel straps to form neat hexagonal bundling units. While this method meets the basic requirements for bulk transportation of drill pipes or tubing, its drawbacks in subsequent on-site dismantling operations become apparent. After the packaged drill pipes or tubing are transported to the oilfield drilling site, the hexagonal steel straps must be dismantled manually or with semi-mechanized equipment, and the plastic caps at the ends of the drill pipes or tubing must be removed manually. This entire dismantling process is highly dependent on manual labor, which is not only time-consuming and labor-intensive, but also inefficient. Furthermore, the removed plastic caps require separate recycling, storage, and transportation, incurring significant additional manpower and time costs. This substantially increases the overall cost of using drill pipes or tubing on-site and hinders the overall efficiency of drilling operations.

[0004] To address the numerous drawbacks of traditional processes, existing technologies have been optimized and improved. Chinese patent CN117699268B proposes a drill pipe storage container solution. This equipment uses vertical partitions inside the container to create independent first and second storage units. A circulating chain inside the container drives the wing plates to form fixed limiting slots, thus achieving orderly and limited storage of the drill pipes. This effectively replaces the traditional steel strapping and manual disassembly process, achieving progress in simplifying drill pipe turnover procedures and reducing plastic cap wear.

[0005] However, this patented technology still has significant structural flaws and fails to fully solve the core problems of drill pipe storage and transportation. Firstly, the two storage units occupy most of the internal space of the housing, and rely on fixed slots for drill pipe positioning. The number of slots is a fixed parameter and cannot be flexibly adjusted, resulting in extremely low utilization of the housing's effective storage space. The number of drill pipes that can be stored at one time is limited, and the batch storage and transportation capacity is insufficient, making it difficult to meet the needs of large-scale drilling operations. Secondly, in actual operations, drill pipe specifications are diverse, and the length and diameter of drill pipes used in different working conditions vary significantly. The fixed slots of this equipment have extremely poor adaptability and cannot meet the positioning requirements of multiple drill pipe specifications.

[0006] More importantly, the fixed slot can only limit the placement of the drill rod foundation, but cannot achieve axial locking. During long-distance transportation, the drill rod inside the container is prone to axial movement due to factors such as vehicle bumps and vibrations during start-stop operation. Frequent impacts occur between drill rods and between the drill rod and the container structure, which can easily cause damage such as drill rod deformation and thread wear. It may also lead to deformation and damage to the internal limiting structure of the container, significantly increasing equipment wear and material scrap costs.

[0007] In summary, how to effectively limit the axial movement of drill pipes or tubing while improving the utilization rate of container space and adapting to the storage of various specifications of drill pipes or tubing, and ensure the stability and safety of the entire process of drill pipe or tubing storage and transportation, has become a core technical challenge that urgently needs to be overcome in the field of drill pipe or tubing storage and transportation. Summary of the Invention

[0008] The technical problem to be solved by this invention is: how to effectively limit the axial movement of drill pipes or tubing while improving the utilization rate of the housing space and adapting to the storage of drill pipes or tubing of various specifications.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention is an intelligent storage box, comprising: a box body, a conveying device arranged inside the box body along its length direction, and an inlet and outlet opening on one end face of the box body along its length direction, the inlet and outlet corresponding to the end of the conveying device; Inside the box, and on both sides of the conveying device, there are storage racks. A baffle is provided on the side of the storage rack near the inlet and outlet, and a fixing plate is provided on the side of the storage rack away from the inlet and outlet. Multiple clamping components are arranged in an array on the fixing plate. Inside the box and above the conveying device, there is a transfer assembly. The transfer assembly transfers the drill rod or oil pipe on the conveying device to the storage rack. When the clamping assembly is activated, the clamping assembly abuts the end of the drill rod or oil pipe against the baffle.

[0010] To illustrate the specific structure of the conveying device, the conveying device includes: a frame, and a roller conveyor mounted on the frame.

[0011] To illustrate the specific structure of the storage rack, the storage rack includes a crossbar, which is fixed to the bottom of the box. The length direction of the crossbar is perpendicular to the length direction of the conveying device. Multiple vertical bars are fixed on the crossbar, and a limiting space for stacking drill pipes or oil pipes is formed between adjacent vertical bars.

[0012] To illustrate the specific structure of the transfer assembly, at least one transfer assembly is provided. The transfer assembly includes a crossbeam, the two ends of which are connected to the corresponding side walls of the housing. An X-axis module is arranged on the crossbeam, and the output end of the X-axis module is connected to a Z-axis module. An electromagnet for adsorbing drill pipes or tubing is connected to the bottom of the Z-axis module.

[0013] Furthermore, an electrical control system is installed inside the enclosure, near the inlet and outlet.

[0014] To illustrate the specific structure of the clamping assembly, the clamping assembly is an electric cylinder, and the output end of the clamping assembly can abut against the end of the drill rod or oil pipe.

[0015] The beneficial effects of this invention are as follows: This invention is an intelligent storage box. Drill rods or tubing can enter laterally from the inlet and outlet in sequence and be placed inside the box by a conveying device. Subsequently, the drill rods or tubing are stacked on the storage rack by a transfer assembly. Since the diameter and length of the drill rods or tubing inside the storage rack are different, the clamping assembly acts on the right end of the drill rod or tubing, forcing the drill rod or tubing to move to the left, so that the left end of the drill rod or tubing abuts against the baffle, thus restricting the axial movement of the drill rod or tubing. In addition, the drill rods or tubing are stacked on the storage rack, and the longitudinal movement of the drill rods or tubing is restricted by their own weight. By increasing the overall height of the storage rack, the number of drill rods or tubing that can be stored can be increased, thereby improving the utilization rate of the space inside the box.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] See Figure 1-6 This embodiment is an intelligent storage box, including: a box body 1, a conveying device 2 arranged inside the box body 1 along its length direction, and an inlet and outlet 11 opened on one end face of the box body 1 along its length direction, the inlet and outlet 11 corresponding to the end of the conveying device 2; the operator can put the drill rod or oil pipe into the box body 1 through the inlet and outlet 11, at which time the end of the drill rod or oil pipe is supported on the conveying device 2, and the conveying device 2 places the drill rod or oil pipe into the box body 1; Inside the housing 1, and on both sides of the conveying device 2, there are storage racks 3. A baffle 4 is provided on the side of the storage rack 3 near the inlet / outlet 11, and a fixing plate 5 is provided on the side of the storage rack 3 away from the inlet / outlet 11. Multiple clamping components 6 are arranged in an array on the fixing plate 5. Inside the housing 1 and above the conveying device 2, there is a transfer assembly 7. The transfer assembly 7 transfers the drill rod or oil pipe on the conveying device 2 to the storage rack 3. The clamping assembly 6 is activated accordingly. The clamping assembly 6 acts on the end of the drill rod or oil pipe and abuts the other end of the drill rod or oil pipe against the baffle 4. In this embodiment, drill rods or tubing can enter laterally from inlet / outlet 11 and be placed inside the housing 1 via conveying device 2. Subsequently, the drill rods or tubing are stacked on the storage rack 3 via transfer assembly 7. Since the drill rods or tubing in the storage rack 3 have different diameters and lengths, the clamping assembly 6 acts on the right end of the drill rod or tubing, forcing the drill rod or tubing to move to the left, so that the left end of the drill rod or tubing abuts against the baffle 4, thus restricting the axial movement of the drill rod or tubing. In addition, the drill rods or tubing are stacked on the storage rack 3, and the longitudinal movement of the drill rods or tubing is restricted by their own weight. By increasing the overall height of the storage rack 3, the number of drill rods or tubing that can be stored can be increased, thereby improving the utilization rate of the space inside the housing.

[0020] Conversely, when the drill pipe or tubing needs to be removed from the housing 1, the clamping assembly 6 moves to the right and the transfer assembly 7 sequentially transfers the drill pipe or tubing to the conveying device 2. The conveying device 2 then conveys the drill pipe or tubing to the left and finally outputs it from the inlet / outlet 11.

[0021] See Figure 3 In some possible embodiments, the conveying device 2 includes: a frame 21 and a roller conveyor 22 disposed on the frame 21; In this embodiment, the drill rod or oil pipe can be placed on the roller conveyor 22 for axial transport. The rollers on the roller conveyor 22 are preferably structured so that the diameters at both ends are larger than the diameter in the middle. In this way, when the drill rod or oil pipe is transported on the roller conveyor 22, the weight of the drill rod or oil pipe itself can be used to accurately position the drill rod or oil pipe in the middle position of the roller conveyor, which is convenient for the subsequent transfer component 7 to adsorb and grasp it.

[0022] See Figure 3 In some possible embodiments, the storage rack 3 includes a crossbar 31, which is fixed to the bottom of the box 1. The length direction of the crossbar 31 is perpendicular to the length direction of the conveying device 2. Multiple vertical bars 32 are fixed on the crossbar 31, and a limiting space 33 for stacking drill pipes or oil pipes is formed between adjacent vertical bars 32. In this embodiment, after the drill pipe or tubing is picked up by the transfer assembly 7, it enters from the top of two adjacent vertical bars 32 and is finally supported on the horizontal bar 31 or stacked on another drill pipe or tubing; the distance between the two vertical bars 32 can be selected to match the diameter of the drill pipe or tubing, that is, drill pipes or tubing of different diameters are placed in different limiting spaces 33.

[0023] See Figure 6 In some possible embodiments, at least one transfer assembly 7 is provided. The transfer assembly 7 includes a crossbeam 71, the two ends of which are connected to the left and right side walls of the housing 1. An X-axis module 72 is arranged on the crossbeam 71. The output end of the X-axis module 72 is connected to a Z-axis module 73. An electromagnet 74 for adsorbing drill rods or tubing is connected to the bottom of the Z-axis module 73. In this embodiment, the transfer components 7 are arranged in two positions on the left and right inside the housing 1. After the electromagnet 74 is energized, the electromagnet attracts the drill rod or oil pipe. The X-axis module 72 moves the drill rod or oil pipe above the two adjacent vertical rods 32. The Z-axis module 73 lowers the drill rod or oil pipe and places it in the limiting space 33. Then the electromagnet 74 is de-energized, and the drill rod or oil pipe is separated from the transfer components 7.

[0024] See Figure 1 , 5 An electrical control system 8 is installed inside the housing 1 and near the inlet / outlet 11.

[0025] In this embodiment, a clamping component 6 is provided on the right side inside the housing 1. The clamping component 6 can be selected as an electric cylinder. Therefore, an electric control system 8 is provided on the left side inside the housing 1. The weight of the electric control system 8 is balanced with the weight of the clamping component 6 to prevent the overall center of gravity of the housing 1 from shifting.

[0026] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
