Description

Technical Field

[0001] This utility model relates to the technical field of drill pipe storage and conveying equipment, and specifically to a drill pipe support frame. Background Technology

[0002] In drilling, coring, or drill pipe assembly operations, multiple drill pipes are often placed on a platform and sequentially picked up by a robotic arm and fed into the next process (such as pipe mounting, assembly, or inspection). The drill pipe support frame is usually located at the top of the platform and has several slots on the top to support the cylindrical drill pipes. The slot shapes are commonly semi-circular slots, V-shaped slots, or bushed round holes. To ensure that the robotic arm can pick up the drill pipes stably and reliably, the support frame must be able to fix the drill pipes in a repeatable position without interfering with the gripping action of the robotic arm.

[0003] In actual working conditions, although drill pipes from the same batch usually use the same specifications, the diameter of drill pipes from different batches or of different types may vary (the diameter of the drill pipes may differ). In addition, there may be differences in surface coating, casing, end shape, etc. Traditional drill pipe support frames are mostly fixed slots or manually replaced with bushings and shims to adapt to different diameters, but this method has obvious shortcomings.

[0004] Standard fixed-size slots can only accommodate a single diameter. If a diameter deviation occurs, the bushing or the entire drill rod support frame needs to be replaced, leading to downtime and manual intervention. Using bushings, shims, or manual adjustment devices to change the slot width is cumbersome and inefficient, unsuitable for frequent specification changes or automated scenarios. Furthermore, the drill rod may fall off during feeding. When the drill rod diameter is too large or too small and the slot cannot fit precisely, the drill rod may tilt, shift laterally, or roll during clamping, increasing the clamping failure rate or damaging the drill rod and clamp. Unstable placement may cause the drill rod to slip when the robotic arm grasps it or due to environmental vibrations, posing risks to equipment damage and personnel safety. Utility Model Content

[0005] The technical problem this utility model aims to solve is that traditional drill rod support frames, when facing drill rods of various specifications, have slot sizes that are not easily adjustable, affecting work efficiency or posing safety hazards. The purpose is to provide a drill rod support frame that allows for flexible adjustment of the slot size according to different drill rod specifications, thereby improving the stability of the drill rod support.

[0006] This utility model is achieved through the following technical solution: A drill pipe support frame, comprising: A storage platform, comprising a storage rack and a support platform, wherein the storage rack is rotatably connected to the top surface of the support platform and is used to store drill rods; A plurality of brackets are provided on one side of the top surface of the support platform. The brackets can rise or fall along the height direction of the support platform. The top surface of the brackets is provided with a receiving groove for supporting and limiting the drill rod. The depth and width of the receiving groove are adjustable.

[0007] In the above technical solution, the depth and width of the bracket receiving groove can be adjusted, so that the same bracket can be used to accommodate drill rods of different diameters. This avoids frequent replacement of fixed-size bushings or bracket parts, thereby improving the flexibility and production continuity when changing specifications, and reducing manual intervention and downtime.

[0008] Preferably, the number of the plurality of brackets is at least two, and the faces of adjacent brackets facing each other are connected by a support plate. A driving member is provided at the bottom of the support plate, and the output end of the driving member is connected to the bottom surface of the support plate.

[0009] In the above technical solution, the combination of support plate and driving component enables synchronous driving and centralized adjustment of group brackets. The setting of at least two brackets can make the drill rod more stable when it is driven to rise.

[0010] Preferably, the bracket includes a support panel, a horizontal support block, and a vertical support block. The tops of the vertical support block and the support panel are both right-angled triangular structures, and their inclined surfaces face each other. The horizontal support block is slidably connected to the bottom of the vertical support block.

[0011] In the above technical solution, the structure of the right-angled triangular inclined planes facing each other allows the slot opening of the receiving groove to obtain centripetal or outward force guidance when it widens or narrows, thereby achieving stable clamping or guidance of the drill rod during the adjustment process.

[0012] Preferably, the support panel has a through groove along the thickness direction, the horizontal support block is slidably connected to the bottom surface of the through groove, the top of the horizontal support block has a first threaded hole, the bottom of the vertical support block has a second threaded hole coaxial with the first threaded hole, the first threaded hole is adapted to be threadedly connected to a screw, and the other end of the screw is adapted to be threadedly connected to the second threaded hole.

[0013] In the above technical solution, during adjustment, the longitudinal support block can be raised by rotating the screw, thereby changing the size of the receiving groove.

[0014] Preferably, the support panel is further provided with a groove along the thickness direction, and the longitudinal support block is connected to a slider that is slidably connected to the groove.

[0015] In the above technical solution, the sliding groove and the slider cooperate to limit the sliding path of the longitudinal support block, improve the guiding accuracy and anti-lateral displacement ability of the whole machine, and prevent tilting or jamming during the adjustment process.

[0016] Preferably, the opening width of the groove is equal to the thickness of the slider, and the groove length is greater than the height of the slider.

[0017] In the above technical solution, the tight fit and restricted movement of the slider in the groove ensures both free sliding and suppresses swaying, thereby increasing positioning stability.

[0018] Preferably, the bottom of the longitudinal support block has a through hole, the screw is located on one side of the through hole, and a fixing nut is fixedly connected to the screw located in the through hole area.

[0019] In the above technical solution, by rotating the fixing nut, the screw can be rotated accordingly, thereby controlling the rise or fall of the longitudinal support block.

[0020] Preferably, the storage rack has a base frame at the bottom, a support roller is provided above the base frame, and a measuring ruler is provided on the side wall of the base frame near the bracket. The measuring ruler is L-shaped and the opening of the measuring ruler faces away from the bracket.

[0021] In the above technical solution, the base frame, together with the support roller, enables the drilling rod to roll and be positioned, facilitating loading or unloading. The L-shaped measuring ruler allows for a direct view of the drilling rod's dimensions.

[0022] Preferably, the base frame has a groove, the measuring ruler is slidably connected in the groove, and the scale lines of the measuring ruler extend to both sides along the included angle.

[0023] In the above technical solution, the measuring ruler slides within the groove to make its position adjustable, adapting to drill rods of different diameters or different placement states.

[0024] Preferably, both the support panel and the horizontal support block have interconnected grooves, and a ruler is connected to the groove on one side of the horizontal support block.

[0025] In the above technical solution, the scale can intuitively show the moving distance when the horizontal support block is moved.

[0026] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. In this utility model, the depth and width of the receiving groove can be changed by moving the longitudinal support block and the transverse support block to adapt to drill rods of different diameters, so that the support point of the receiving groove for large-diameter drill rods is increased accordingly, and the receiving groove is not too small and cannot effectively support the drill rod. 2. In this utility model, the setting of the measuring ruler and scale allows for the observation of the diameter of the drill rod after changing to different specifications, and enables the corresponding and intuitive adjustment of the moving distance of the horizontal support block to adjust the size of the receiving groove.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage.

[0030] Example 1: like Figure 1 and Figure 2 As shown, this embodiment 1 provides a drill pipe support frame, including: The storage platform includes a storage rack 11 and a support platform 12. The storage rack 11 is rotatably connected to the top surface of the support platform 12 and is used to store drill rods. Several brackets 2 are arranged on one side of the top surface of the support platform 12. The brackets 2 can rise or fall along the height direction of the support platform 12. The top surface of the brackets 2 is provided with a receiving groove 24, which is used to support and limit the drill rod. The depth and width of the receiving groove 24 are adjustable.

[0031] like Figure 1 and Figure 2 As shown, the number of brackets 2 is at least two, and the faces of adjacent brackets 2 facing each other are connected by a support plate 3. A driving component is provided at the bottom of the support plate 3, and the output end of the driving component is connected to the bottom surface of the support plate 3.

[0032] like Figures 1 to 4As shown, the bracket 2 includes a support panel 21, a horizontal support block 22 and a vertical support block 23. The tops of the vertical support block 23 and the support panel 21 are both right-angled triangular structures, and their inclined surfaces face each other. The horizontal support block 22 is slidably connected to the bottom of the vertical support block 23.

[0033] like Figures 1 to 4 As shown, the support panel 21 has a through groove along the thickness direction, the horizontal support block 22 is slidably connected to the bottom surface of the through groove, the top of the horizontal support block 22 has a first threaded hole, the bottom of the vertical support block 23 has a second threaded hole coaxial with the first threaded hole, the first threaded hole is threadedly connected to a screw 5, and the other end of the screw 5 is threadedly connected to the second threaded hole.

[0034] like Figures 1 to 4 As shown, the support panel 21 is also provided with a groove along the thickness direction, and the longitudinal support block 23 is connected with a slider 4 that is slidably connected to the groove.

[0035] like Figures 1 to 4 As shown, the opening width of the groove is equal to the thickness of the slider 4, and the groove length is greater than the height of the slider 4.

[0036] like Figures 1 to 4 As shown, a through hole is provided at the bottom of the longitudinal support block 23, and the screw 5 is located on one side of the through hole. A fixing nut 51 is fixedly connected to the screw 5 located in the through hole area.

[0037] Specifically, drill rods from the same batch can be placed on the storage rack 11 for temporary storage. Preferably, the storage rack 11 has a rotating shaft at one end near the bracket 2, which is rotatably connected to the support platform 12. The storage rack 11 can rotate upward along the rotating shaft to an inclined state, and the drill rods will roll into the receiving groove 24 on the bracket 2. The bracket 2 drives the drill rods in the receiving groove 24 to rise through the drive component, and the drill rods are picked up by the robotic arm to complete the rod delivery work. The drive component can be a cylinder, hydraulic cylinder, etc.

[0038] Regarding the principle of adjusting the diameter of the bracket 2 receiving groove 24: When the drill rod diameter is larger than the initial maximum receiving size of the receiving groove 24, the size needs to be adjusted to accommodate the larger diameter drill rod, so as to avoid the drill rod not being effectively supported and shaking or even tilting and falling off during the rod feeding process.

[0039] First, the horizontal support block 22 is pulled outward. The horizontal support block 22 is rectangular. The support panel 21 is provided with a limiting groove for the horizontal support block 22 to slide. The upper and lower sides of the limiting groove are provided with guide rails. The upper and lower sides of the horizontal support block 22 are fixedly connected with guide blocks that slide with the guide rails. When the horizontal support block 22 is pulled to move, the guide blocks slide along the guide rails and limit the horizontal slider 4, forcing the horizontal slider 4 to slide in the horizontal direction. The longitudinal support block 23 is threadedly connected to the first threaded hole on the horizontal support block 22 through the screw 5. Therefore, when the horizontal slider 4 moves, it will also drive the longitudinal slider 4 to move horizontally.

[0040] Next, the fixing nut 51 can be rotated using tools such as a wrench. The fixing nut 51 is fixed on the screw 5 in the through hole area. When the fixing nut 51 is rotated, the screw 5 rotates with the fixing nut 51, and it is not only the fixing nut 51 that rotates to rise or fall. As the screw 5 rotates, the second threaded hole on the lifting longitudinal support block 23 rises. When the longitudinal support block 23 rises or falls, it moves with the help of the guide action of the slider 4 sliding in the groove. At this time, the diameter of the receiving groove 24 on the bracket 2 has changed. The receiving groove 24 on the side closer to the longitudinal support block 23 has a deeper and higher support point for the drill rod, which avoids the drill rod being too large and the support point of the receiving groove 24 being too low and unstable.

[0041] Preferably, the bottom surface of the second threaded hole is provided with an annular groove, and the top surface of the screw 5 is fixedly connected to a rotating platform. The rotating platform is rotatably connected in the annular groove. When the screw 5 rises, the rotating platform pushes the annular groove, thereby causing the longitudinal support block 23 to rise. When the screw 5 falls, the rotating platform drives the annular groove downward, thereby causing the longitudinal support block 23 to move downward.

[0042] Example 2: like Figure 1 and Figure 2 As shown, a base frame 13 is provided at the bottom of the storage rack 11, and a support roller 14 is provided above the base frame 13. A measuring ruler 6 is provided on the side wall of the base frame 13 near the bracket 2. The measuring ruler 6 is L-shaped, and the opening of the measuring ruler 6 is away from the bracket 2.

[0043] like Figure 1 and Figure 2 As shown, a groove is provided on the base frame 13, and the measuring ruler 6 is slidably connected in the groove. The scale lines of the measuring ruler 6 extend to both sides along the included angle.

[0044] like Figure 3 and Figure 4 As shown, both the support panel 21 and the horizontal support block 22 have interconnected grooves 25. A scale 7 is connected in the groove 25 on one side of the horizontal support block 22, and the 0 mark of the scale 7 is located at the end of the groove 25 on one side of the horizontal support block 22.

[0045] Specifically, after the drill rods are placed in the storage rack 11, they remain temporarily on the support roller 14, arranged in sequence without being stacked. Then, the measuring ruler 6 on the sliding base frame 13 slides along the groove to the side near the bracket 2 to measure the first drill rod on the side near the bracket 2. The measuring ruler 6 is L-shaped, with the scale lines extending to both sides along the included angle, which allows for a direct and effective observation of the diameter of the drill rods in the current batch.

[0046] After understanding the diameter of the drill rod in the current batch, the distance between the longitudinal support block 23 and the transverse support block 22 can be adjusted as needed. When the transverse support block 22 moves, it drives the scale 7 to slide along the groove 25. Preferably, the 0 mark of the scale 7 is located at the end of the groove 25 on the transverse support block 22, so that the moving distance of the transverse support block 22 can be controlled intuitively and effectively after the transverse support block 22 moves.

[0047] Example 3: Based on Embodiments 1 and 2, a telescopic plate is provided between the storage rack 11 and the base frame 13. The storage rack 11 is used to store and restrict the drill rods to prevent them from falling during placement or rolling, or to prevent multiple drill rods from being misaligned, which would cause them to shift in position when placed on the bracket 2. More preferably, the telescopic plate can adjust the distance between the storage rack 11 and the base frame 13, and can flexibly adjust the position of the storage rack 11 when the lengths of the drill rods are different, so as to avoid the distance between the two storage racks 11 being too short to effectively restrict the drill rods.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
