Description

Technical Field

[0001] This invention relates to the field of geological drilling machinery and equipment technology, and in particular to a drill pipe box and a drill pipe transport device. Background Technology

[0002] With the continuous improvement of automation in geological drilling, drill pipe transportation and retrieval operations are gradually shifting from manual to mechanized and automated processes. As a key piece of equipment for drill pipe storage and transportation, the drill pipe box's structural design directly affects the efficiency and safety of drilling operations.

[0003] In existing technologies, hydraulically controlled drill rod box devices typically employ a nested inner and outer frame structure. The inner frame is hydraulically driven to rise, fall, and tilt, allowing the drill rod to be transported or retrieved layer by layer under its own weight. However, the inner frame of existing technologies integrates multiple functional components such as multi-layer drill rod stops and adjusting springs, resulting in a large number of parts and high assembly precision requirements. The main body of the inner frame needs to be precisely matched with the surrounding guide pulleys and the multi-layer stop adjustment mechanism, making the processing steps cumbersome and significantly increasing the overall manufacturing cost. Furthermore, adjusting the drill rod stop spacing in existing technologies requires loosening the fixing pins layer by layer, compressing or releasing the adjusting springs, and then relocking the fixing pins. The operation steps are cumbersome and cannot be completed quickly on-site. For operation scenarios that require frequent changes in drill rod specifications, this adjustment method seriously affects operational efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a drill pipe box and a drill pipe transport device to solve the problems existing in the prior art, thereby reducing the difficulty of operation and improving drilling efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 This invention provides a drill pipe box, such as Figure 1-3 As shown, the enclosure includes a housing 1, a lifting mechanism 6, and an adjusting mechanism 5. The housing 1 stores drill rods. The adjusting mechanism 5 is located on the outside of the housing 1 and is used to adjust the height and / or tilt angle of the housing 1. The lifting mechanism 6 is located on the housing 1 and is used to lift or lower the drill rods inside the housing 1. The lifting mechanism 6 can lift the drill rods to the top outlet of the housing 1 so that the drill rods can roll out of the housing 1 under their own weight. In this embodiment, by placing the adjusting mechanism 5 on the outside of the housing 1, the internal frame structure of the housing 1 is simplified, significantly reducing the number of parts and the assembly precision requirements, thereby reducing the manufacturing difficulty and production cost of the housing 1. At the same time, the external adjusting mechanism 5 can directly adjust the height and tilt angle of the entire housing 1, providing ample operating space and facilitating quick on-site adjustment of the drill rod box's state, effectively reducing maintenance difficulty and cycle.

[0022] In some embodiments of this example, the adjustment mechanism 5 includes multiple adjustable legs. The length of the adjustable legs can be adjusted, and the height and / or tilt angle of the housing 1 can be adjusted. The adjustment mechanism 5 includes multiple adjustable legs, and the length of each leg can be adjusted independently. By adjusting the extension and retraction of each leg, the housing 1 can form the required tilt angle. The drill rod rolls along the tilt direction under its own weight and moves out from the top outlet of the housing 1. Automatic conveying of the drill rod can be achieved without relying on a complex inner frame lifting and tilting mechanism, which simplifies the internal structure of the housing 1.

[0023] In some embodiments of this example, there are four adjustable legs, which are respectively located at the four corners of the housing. The four adjustable legs are respectively located at the four corners of the housing 1, forming a stable four-point support structure, so that the weight of the housing 1 and the drill rod inside it is evenly distributed on each leg, which significantly improves the overall stability and load-bearing capacity of the device. At the same time, by independently adjusting the extension and retraction of the four corner legs, the tilt angle and height of the housing 1 in any direction, front-back or left-right, can be flexibly controlled. This not only makes it easy to quickly level the housing to adapt to uneven ground, but also can accurately form the conveying tilt angle required for the drill rod to roll.

[0024] In some embodiments of this example, the adjustable outrigger includes a telescopic component. The use of a telescopic component allows for automatic extension and retraction of the outrigger length via a drive mechanism, eliminating the need for manual tightening or disassembly of pads. This makes operation labor-saving, convenient, and highly efficient. Simultaneously, the telescopic component provides stable and continuous support and maintains the smooth lifting and lowering of the housing during adjustment, avoiding the risk of the housing swaying or tipping over due to unstable support during manual adjustment. Furthermore, the telescopic component facilitates integration with the electrical control system, enabling remote control and precise adjustment of the outrigger length, further enhancing the automation level of the drill rod and the convenience of on-site operations.

[0025] In some embodiments of this example, the telescopic component is a hydraulic cylinder. The telescopic component of the adjustable outrigger uses a hydraulic cylinder, utilizing the characteristics of high output force and smooth transmission of the hydraulic system to provide strong and reliable support for the housing 1 and its fully loaded drill rod, ensuring the stability of the outrigger telescopic adjustment under heavy load conditions. Simultaneously, the telescopic stroke of the hydraulic cylinder is easy to precisely control, enabling fine-tuning of the height and inclination angle of the housing 1, ensuring the accuracy of the drill rod rolling conveying slope. Furthermore, the hydraulic cylinder can be integrated with the existing hydraulic control system of the drill rod box, facilitating unified oil supply and centralized control, reducing the cost of additional power sources, and also enabling synchronous or independent driving of multiple adjustable outriggers, further improving the automation level of the device and on-site adjustment efficiency.

[0026] In some embodiments of this example, the four adjustable legs are divided into two groups, with two adjustable legs in each group symmetrically arranged on the same side of the housing. The two adjustable legs in the same group rise and fall synchronously to adjust the height of one side of the housing. The four adjustable legs are divided into two groups, with two adjustable legs in each group rising and falling synchronously to adjust the height of one side of the housing, so that the housing 1 can form a stable overall tilt around its longitudinal axis. The tilt angle adjustment is more uniform and controllable, avoiding the distortion and deformation of the housing 1 or the damage of the support leg due to uneven force when a single support leg is adjusted independently. At the same time, the grouped synchronous drive simplifies the control logic, reduces the number of independently controlled support legs, and reduces the complexity of hydraulic pipeline layout and electrical control system, making it easier to operate and maintain quickly on site. In addition, the synchronous lifting on one side can make the top outlet of the housing form a smooth docking slope with the adjacent drill rod box or pipe rack, ensuring that the drill rod rolls stably in the predetermined direction under its own weight, improving the reliability and continuity of drill rod transportation.

[0027] In some embodiments of this example, the lifting mechanism 6 includes a driving mechanism and a lifting member 2. One end of the lifting member 2 is fixed to the housing 1, and the other end is connected to the driving mechanism. The drill rod is placed on the lifting member 2. The driving mechanism is used to raise and lower the lifting member 2 to change the position of the drill rod inside the housing 1. Alternatively, one end of the lifting member 2 is fixed to the housing 1, and the other end is connected to the driving mechanism. The drill rod is directly placed on the lifting member 2. The driving mechanism can change the position of the drill rod inside the housing 1 by driving the lifting member to tension or relax, eliminating the need for a complex inner frame lifting structure and multiple layers of stops. The rod adjustment mechanism significantly simplifies the internal structure of the housing 1. Meanwhile, the lifting component 2 has a flexible contact with the drill rod, smoothly lifting it upwards when tensioned and lowering it layer by layer when relaxed, resulting in gentle, impact-free movement and effectively preventing damage to the drill rod surface from rigid lifting mechanisms. Furthermore, the support height of the drill rod can be flexibly adjusted by controlling the tension of the lifting component 2, enabling layer-by-layer lifting and release of drill rods at different levels. Operation is simple, control precision is high, and the lifting component 2 has a simple structure and is easy to maintain, reducing the manufacturing and maintenance costs of the device.

[0028] In some embodiments of this example, the driving mechanism includes a driving component and a pulley mechanism. The pulley mechanism is mounted on the housing 1, with one end of the lifting component 2 fixed to the housing 1 and the other end connected to the pulley mechanism. The driving component drives the pulley mechanism to rotate and retract the lifting component 2. The pulley mechanism, with one end of the lifting component 2 fixed to the housing 1 and the other end connected to the pulley, drives the pulley mechanism to rotate and retract the lifting component 2. This allows the retraction and retraction of the lifting component 6 to be guided by the pulley mechanism, changing the direction of force transmission and facilitating the rational arrangement of the driving component on the housing 1. It eliminates the need to directly mount the driving component above the lifting component 2, optimizing the internal spatial layout of the housing 1. Simultaneously, the pulley mechanism effectively reduces the frictional resistance between the lifting component 2 and the housing 1, making the movement of the lifting component 6 smoother and less strenuous, and reducing the power loss of the driving component. Furthermore, the cooperation structure between the pulley mechanism and the lifting component 6 is simple and reliable, allowing for flexible adjustment of the pulley's installation position and the winding method of the transmission component according to the size of the housing 1 and the drill rod conveying stroke, thus improving the structural adaptability and ease of maintenance of the device.

[0029] The drive components can be rotary drive devices such as hydraulic motors, electric motors, or pneumatic motors, allowing the device to flexibly select the appropriate drive form according to the on-site power source conditions. Hydraulic motors have high output torque and a wide speed range, making them suitable for heavy-duty and stepless speed regulation conditions. Electric motors offer high control precision and fast response, facilitating automation and remote control. Pneumatic motors, on the other hand, are explosion-proof, simple in structure, and adaptable to harsh environments, thus broadening the device's adaptability to different power configurations and safety requirements at various work sites. Furthermore, all drive components are mature, standardized products with reliable technology, easy procurement and maintenance, and can precisely adjust the lifting and lowering speeds of the lifting components by controlling the rotation speed, thereby accurately controlling the lifting height and release timing of the drill rod, improving the stability and controllability of the drill rod conveying process.

[0030] In some embodiments of this example, the pulley mechanism includes a first pulley 4 and a second pulley 3. The first pulley 4 is disposed at the top of the housing 1, and the second pulley 3 is disposed at the bottom of the housing 1. One end of the lifting member 2 is fixed to the housing 1, and the other end first passes over the first pulley 4 and is then fixed to the second pulley 3. The driving member is fixedly connected to the second pulley 3 and is used to drive the second pulley 3 to rotate. The pulley mechanism includes a first pulley 4 and a second pulley 3. The first pulley 4 is disposed at the top of the housing 1, and the second pulley 3 is disposed at the bottom of the housing 1. One end of the lifting member 2 is fixed to the housing 1, and the other end first passes over the first pulley 4 and is then fixed to the second pulley 3, so that the lifting member 2 forms a reciprocating motion through the guidance of the top and bottom pulleys. The retraction and extension path effectively doubles the stroke of the lifting component 2 within the limited height of the housing 1, thus meeting the requirement for a larger lifting height of the drill rod from the bottom to the top outlet without increasing the height of the housing 1. Simultaneously, the cooperation between the first pulley 4 and the second pulley 3 keeps the supporting section of the lifting component 2 vertical or nearly vertical, ensuring smooth operation of the drill rod without lateral swaying during lifting and effectively preventing collisions between the drill rod and the inner wall of the housing 1. Furthermore, the drive component only needs to rotate the second pulley 3 to retract and extend the lifting component 2; the force transmission path is clear and simple, facilitating precise control of the displacement of the lifting component 2, thereby accurately controlling the lifting height of the drill rod and the timing of layer-by-layer release, improving the accuracy and reliability of drill rod delivery.

[0031] The lifting component 2 can be a flexible component, specifically a wire rope or chain, allowing the device to flexibly select appropriate materials and specifications based on the drill rod weight, lifting stroke, and working environment. Wire ropes have the advantages of being lightweight, flexible, and suitable for long-distance lifting, while chains have the characteristics of high load-bearing capacity, wear resistance, and high transmission accuracy, thus broadening the device's adaptability to different working conditions and load conditions. At the same time, when the flexible component is used in conjunction with pulleys or sprockets, it can smoothly bypass the guide wheel to change the direction of movement, facilitating a compact arrangement of the transmission path inside the housing and effectively saving installation space. In addition, wire ropes or chains are standardized products, easy to purchase and replace, with low maintenance costs, and their tension and slack states are intuitively discernible, allowing operators to judge the working status of the lifting component in real time, improving the maintainability and operational reliability of the device.

[0032] Example 2 This invention also provides a drill pipe transport device, including a storage arm, a catwalk, and a drill pipe box as described in Embodiment 1. The storage arm is disposed between the drill pipe box and the catwalk, used to transfer drill pipes from the drill pipe box to the catwalk, or from the catwalk to the drill pipe box. The storage arm, also disposed between the drill pipe box and the catwalk, serves as a transitional transfer device between the two, allowing the drill pipes to be temporarily stored on the storage arm after rolling out from the top outlet of the drill pipe box. The storage arm then transfers the drill pipes to the catwalk, or conversely, receives the drill pipes from the catwalk and transfers them to the drill pipe box. This achieves segmented connection of the drill pipe transport process, avoiding... This design eliminates the risk of impact, collision, or falling when drill rods roll directly from the drill rod box to the catwalk due to distance or docking misalignment. Simultaneously, the storage arm's temporary storage function allows for independent conveying rhythms between the drill rod box and the catwalk. The drill rod box can continuously release drill rods layer by layer to the storage arm, while the catwalk retrieves drill rods from the storage arm according to its own operating rhythm, improving coordination and overall operational efficiency. Furthermore, the storage arm allows for more flexible spatial arrangement of the drill rod box and catwalk, reducing stringent requirements on installation location and docking accuracy, and facilitating rapid deployment and adjustment of equipment on-site.

[0033] The specific usage process of this drill pipe box device is as follows: Drill pipe delivery process: First, multiple drill pipe box modules are connected in series on both sides of the catwalk machine via connecting ear plates. The extension and retraction of the adjustable legs of each module are adjusted according to the ground conditions on site, so that the top outlet of each box 1 forms a continuous conveying slope that gradually decreases from the outside to the inside, and ensures that the innermost drill pipe box is smoothly connected to the storage arm.

[0034] Then, the lifting mechanism of the outermost drill rod box is activated. The drive unit drives the second pulley 3 to rotate, causing the lifting unit 2 to be tensioned, and smoothly lifting the bottommost drill rod to the top outlet of the housing 1. At this time, the adjusting legs of the drill rod box keep the housing 1 tilted inward. Under its own weight, the drill rod rolls along the top surface of the tilted housing 1, slides through the top outlet into the top of the adjacent inner drill rod box or directly into the storage arm.

[0035] When multiple drill rod boxes are set on each side, the drill rods in the outer drill rod box must pass through the top of the box of each drill rod box between the outer drill rod box and the storage arm before entering the storage arm. That is, after the drill rods are taken out from the outer drill rod box, they are delivered horizontally inward, passing through the top of the box of each intermediate drill rod box as a transition support surface, and finally reaching the receiving position of the storage arm. With this setting, there is no need to set up a separate conveying channel or transfer mechanism between the outer drill rod box and the storage arm. The top of the box of each intermediate drill rod box naturally forms a continuous drill rod transfer path, which simplifies the equipment structure and makes full use of the existing space, making the transfer of drill rods in the multi-layer drill rod box layout smoother and more efficient.

[0036] When only one drill rod box is set on each side, the drill rod in the drill rod box can be directly taken out from the drill rod box and put into the storage arm without passing through the top of the box of other drill rod boxes. With this setting, the drill rod transfer path is the shortest, the picking and putting action is the most direct and convenient, the support links of the drill rod during the transfer process are reduced, the risk of surface damage to the drill rod is reduced, the operation process is simplified, and the drill rod replacement efficiency under the single drill rod box configuration is improved.

[0037] Next, following the order from the outside in, the lifting mechanisms 6 of each drill pipe box are controlled sequentially to lift the drill pipes in the box 1 layer by layer to the top outlet and release them. When the lifting component 2 relaxes, the upper drill pipes fall to the lower support position, waiting for the next lifting. The above lifting and releasing actions are repeated until all drill pipes in the drill pipe box have been delivered.

[0038] After receiving the drill rod from the drill rod box, the storage arm temporarily stores it on the arm. Then, according to the operation rhythm of the catwalk machine, the drill rod is transferred to the catwalk machine, completing the transfer of the drill rod from the drill rod box to the catwalk machine.

[0039] Drill pipe recovery process: The process operates in the reverse order of the conveying process. The catwalk conveyor transfers the drill rods to the storage arm, which then transfers them to the top of the innermost drill rod box. Under its own weight, the drill rods roll into box 1 and are placed on the lifting member 2. The drive unit rotates the second pulley 3 in the opposite direction to release the lifting member 2, and the drill rods are lowered to the corresponding height within box 1 under gravity. After the lifting member 2 relaxes, the drill rods are stably supported by the lifting member 2 or the lower drill rods. Following a sequence from the inside out, each drill rod box is sequentially controlled to retrieve the drill rods until all drill rods are stored.

[0040] Shipping status: After the drill pipe is recovered, the connecting lug pins between adjacent drill pipe boxes are removed, making each drill pipe box an independent module. The adjustable outriggers are then retracted to their shortest position, allowing the skid structure to directly contact the ground, facilitating the hoisting and transport of vehicles and enabling the rapid overall transport of the drill pipe boxes and drill pipes.

[0041] Specific examples have been used in this invention to illustrate the principles and implementation methods of the invention. The above description of the embodiments is only for the purpose of helping to understand the method of the invention and its limitations.
