Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a novel lifting disc welded component for heat treatment of composite drill pipe provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the connecting device. Figure 3 for Figure 1 The diagram shows a composite drill pipe lifting device. A novel welded lifting device for heat treatment of composite drill pipe includes: a large lifting plate 1 and a sector-shaped plate 3.

[0029] Mounting groove 2, the mounting groove 2 is formed on the surface of the large hanging plate 1, the fan-shaped plate 3 is disposed inside the mounting groove 2, and the surface of the fan-shaped plate 3 is provided with mounting holes 4;

[0030] The connecting device 5, two of which are respectively disposed on both sides inside the sector disk 3, the connecting device 5 includes a welding rod 51, an external thread end 52 and a T38 ferrule 53;

[0031] The composite drill pipe lifting disc 6 is disposed at the bottom of the connecting device 5. The composite drill pipe lifting disc 6 includes a disc body 61, an opening hole 62, and a drill pipe hole 63.

[0032] Composite drill rods 7, two of which are respectively disposed on both sides of the surface of the composite drill rod lifting disc 6.

[0033] The disc body 61 is disposed at the bottom of the welding rod 51, the two opening holes 62 are respectively opened on both sides of the surface of the disc body 61, and the two drill holes 63 are respectively opened on the other two sides of the surface of the disc body 61.

[0034] The top of the outer surface of the welding rod 51 is fixedly installed with an external thread end 52, and the outer surface of the external thread end 52 is threaded with a T38 ferrule 53.

[0035] The composite drill rod 7 is disposed inside the drill rod hole 63.

[0036] Based on the use of T38 ferrule 53, the thread of T38 ferrule 53 engages with the outer surface of the external thread end 52. The thread length and total length need to be suitable. The holes 62 on both sides of the designed composite drill rod lifting disc 6 are the same size as the welding rod 51 and are concentric. The diameters of the other two drill rod holes 53 are slightly larger than the outer diameter of the composite drill rod 7 but smaller than the outer diameter of the spline, which is used to stabilize the composite drill rod 7. Based on this, a solid rod is selected as the welding rod 51 (the length of the welding rod 51 must be greater than that of the composite drill rod 7). The upper end of the composite drill rod 7 (spline) is welded to the external thread end 52 and the composite drill rod lifting disc 6 respectively. After the two composite drill rods 7 are placed into the drill rod hole 63 of the lifting disc, they will not fall off because the spline is larger than the drill rod hole 63 of the lifting disc. After the two external thread ends 52 are passed through the mounting hole 4 of the sector disc, the T38 ferrule 53 is installed above the sector disc 3. The ferrule engages with the external thread end 52 through the threaded engagement between the threads, thus achieving the lifting of the composite drill rod 7.

[0037] The working principle of the novel lifting disc welded component for composite drill pipe heat treatment provided by this utility model is as follows:

[0038] During operation, the top of the welding rod 51 is first passed upward through the mounting hole 4, and the T38 ferrule 53 is threaded onto the outer surface of the external thread end 52, thus confining the connecting device 5 to the surface of the sector disk 3.

[0039] After the two composite drill rods 7 are respectively inserted into the drill rod holes 63, the surface of the composite drill rods 7 is provided with splines. Since the splines are larger than the drill rod holes 63, they will not fall off.

[0040] Compared with related technologies, the novel lifting disc welded component for heat treatment of composite drill pipe provided by this utility model has the following beneficial effects:

[0041] This utility model provides a novel lifting device for heat treatment of composite drill rods. The welding rod 51 passes through the mounting hole 4 on the surface of the fan-shaped disc 3. The welding rod 51 is then secured to the surface of the large lifting disc 1 using the external threaded end 52 and a T38 ferrule 53. The composite drill rod lifting device 6 and the composite drill rod 7 are connected and assembled. After stabilization is achieved by the ferrule and external threaded end, the composite drill rod 7 can be lifted. This solves the problem that composite drill rods cannot be heat-treated in a carburizing furnace. Furthermore, it is convenient to use, provides good lifting stability, and effectively solves the problem of lifting composite drill rods in carburizing furnaces during production.

[0042] Second Embodiment

[0043] Please refer to the following: Figure 4 , Figure 5 and Figure 6 Based on the first embodiment of this application, which provides a novel lifting disc welded component for heat treatment of composite drill pipe, the second embodiment of this application proposes another novel lifting disc welded component for heat treatment of composite drill pipe. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a novel lifting device disc welding component for heat treatment of composite drill pipe, wherein a receiving groove 8 is provided on one side of the outer surface of the welding rod 51, and an elastic device 10 is fixedly connected inside the receiving groove 8. A limiting device 9 is slidably installed on one side of the outer surface of the elastic device 10. The limiting device 9 includes a limiting block 91, a connecting hole 92, a moving cavity 93, and a pressing inclined surface 94.

[0045] The elastic device 10 includes a fixed rod 101, a movable block 102, and a spring 103. The fixed rod 101 is fixedly installed inside the storage groove 8, the movable block 102 is fixedly installed at one end of the fixed rod 101, and the spring 103 is sleeved on one side of the outer surface of the fixed rod 101.

[0046] The limiting block 91 is sleeved on one side of the outer surface of the fixing rod 101, the connecting hole 92 is opened on one side of the outer surface of the limiting block 91, the moving cavity 93 is opened inside the limiting block 91, and the extrusion slope 94 is provided on the other side of the outer surface of the limiting block 91.

[0047] The working principle of the novel lifting disc welded component for composite drill pipe heat treatment provided by this utility model is as follows:

[0048] When it is necessary to disassemble the connecting device 5 during operation, the user can press and squeeze the inclined surface 94 to move the limiting block 91 into the storage groove 8. The limiting block 91 slides on the surface of the fixed rod 101 through the connecting hole 92 and the moving cavity 93. The limiting block 91 squeezes the spring 103 and the limiting block 91 is embedded into the storage groove 8, making it convenient for the welding rod 51 to be taken out from the mounting hole 4.

[0049] When the user releases the squeezing block 91, part of the spring 103's restoring elasticity limit block 91 moves out of the storage slot 8, causing the limit block 91 to block the surface of the fan-shaped disk 3.

[0050] Compared with related technologies, the novel lifting disc welded component for heat treatment of composite drill pipe provided by this utility model has the following beneficial effects:

[0051] This utility model provides a novel welding component for a lifting disc used in the heat treatment of composite drill pipes. The limiting block 91 is pushed by the restoring force of the spring 103, causing it to partially move out of the receiving groove 8. The limiting block 91 is then locked onto the surface of the fan-shaped disc 3. When the connecting device 5 needs to be disassembled, the user can press and squeeze the inclined surface 94 to move the limiting block 91 into the receiving groove 8, facilitating the removal of the welding rod 51 from the mounting hole 4. This device has a simple structure, strong practicality, and allows operators to easily install the welding rod 51 onto the surface of the large lifting disc 1. The welding rod 51 is easy to install and disassemble, improving the convenience of this device.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
