[0036] Figure 1 This is a top view of the track assembly provided in this embodiment of the utility model.

[0037] See Figure 1 This utility model provides a track assembly, which includes a track body 10 and a drag chain groove 20.

[0038] The track body 10 serves as the main road for the operation of the mobile trolley 40, and is suitable for guiding the mobile trolley 40 to move along a preset path. The track body 10 is made of high-strength material and has sufficient hardness and toughness to withstand frequent loads and impacts.

[0039] The cable chain groove 20 is located on one side of the track body 10 and is arranged along the layout path of the track body 10. The cable chain groove 20 includes a first segment 21, a second segment 22 and a third segment 23 connected in sequence. The first segment 21 and the third segment 23 are arranged perpendicularly. The second segment 22 is located between the first segment 21 and the third segment 23 and is connected to the first segment 21 and the third segment 23 respectively. The third segment 23 is suitable for fixing the cable chain 30.

[0040] Since the drag chain trough 20 is set along the layout path of the track body 10, the track body 10 is equivalent to being composed of three segments connected in sequence to form an "L"-shaped track body 10, which is suitable for the movement of the trolley 40 of the drilling platform robot.

[0041] In this cable chain trough 20, roller assemblies are spaced along corresponding paths in the first segment 21, the second segment 22, and the third segment 23. These roller assemblies are designed for rolling contact with the cable chain 30, reducing friction between the cable chain 30 and the cable chain trough 20 by converting sliding friction into rolling friction, thus making the cable chain 30 move more smoothly with the trolley. Furthermore, adjusting the contact surface between the roller assemblies and the cable chain 30 reduces operating noise, creating a quieter working environment.

[0042] It is understood that the track assembly provided in this embodiment of the present invention has the cable chain groove 20 disposed on one side of the track body 10 and arranged along the layout path of the track body 10, so that the cable chain groove 20 includes a first segment 21, a second segment 22 and a third segment 23 connected in sequence. Each segment is provided with roller assemblies at intervals along a corresponding path. The roller assemblies are adapted to make rolling contact with the cable chain 30, which can reduce the friction between the cable chain 30 and the cable chain groove 20, that is, convert the original sliding friction into rolling friction, making the cable chain 30 move more smoothly with the trolley. Furthermore, by adjusting the contact surface between the roller assembly and the cable chain 30, the operating noise can be reduced, making it easier to create a quiet working environment.

[0043] Figure 2 This is a schematic diagram of the structure of the drag chain groove 20 in the track assembly provided in this embodiment of the utility model. Figure 3 This is a top view of the drag chain groove 20 in the track assembly provided in this embodiment of the utility model.

[0044] See Figure 2 and Figure 3 In some embodiments of this utility model, the first segment 21 includes a first baffle 211 and a second baffle 212 disposed opposite to each other. A first connecting plate 213 connects the first baffle 211 and the second baffle 212. A portion of the first connecting plate 213 extends out of the first baffle 211 or the second baffle 212 and connects to the track body 10, ensuring a tight connection between the entire first segment 21 and the track body. The first baffle 211, the second baffle 212, and the first connecting plate 213 restrict the working groove segment 214. First roller assemblies 215 are spaced apart within the working groove segment 214. The first roller assemblies 215 are offset from the first connecting plate 213, and each first roller assembly 215 has an equal length.

[0045] The parallel first baffle 211 and second baffle 212 form the basic framework of the working groove section 214. The first connecting plate 213 reinforces the connection between the first baffle 211 and the second baffle 212, enhancing the rigidity of the overall structure. In other words, the first baffle 211, the second baffle 212, and the first connecting plate 213 enclose a long, narrow channel as the working groove section 214, which provides a defined movement path for the cable chain 30.

[0046] By adjusting the distance between the first baffle 211 and the second baffle 212 according to the size and shape of the cable chain 30, it can be ensured that the cable chain 30 slides freely in the working groove section 214, that is, the cable chain 30 does not rub against the edge during operation, and at the same time avoids falling off.

[0047] The first roller assemblies 215 are spaced apart inside the working groove section 214. Each first roller assembly 215 has a uniform length, ensuring that the cable chain 30 is subjected to balanced force when rolling on it. The rolling contact between the first roller assembly 215 and the cable chain 30 greatly reduces the coefficient of friction, allowing the cable chain 30 to move forward smoothly with less power, while also reducing noise during operation. Furthermore, the first roller assembly 215 absorbs and disperses the impact force from the cable chain 30 through its own rotation, effectively slowing down the wear rate of the cable chain 30 and extending its service life.

[0048] Continue reading 2 and Figure 3 In some embodiments of this utility model, a first gap 216 is formed between two adjacent first roller assemblies 215, and between each first roller assembly 215 and the adjacent first connecting plate. The first gap 216 facilitates the discharge of mud and other impurities that fall into the working trough section 214.

[0049] Because the operating environment of the drilling platform robot is poor, it is exposed to the outdoors, and mud splashes on the drilling platform. The dried mud easily accumulates in the cable carrier's groove plate, making the cable carrier difficult to install and the cables easily damaged.

[0050] In this utility model, when the drag chain 30 drives the first roller assembly 215 to rotate, the mud, dust or other small impurities it carries will be carried to the first gap 216 and fall to the ground from the first gap 216, which facilitates the cleaning of impurities in the working trough section 214.

[0051] See Figure 2 and Figure 3In some embodiments of this utility model, the second segment 22 includes a first arc plate 221 and a second arc plate 222. A second connecting plate 223 connects the first arc plate 221 and the second arc plate 222. Part of the second connecting plate 223 extends out of the first arc plate 221 or the second arc plate 222 and connects to the track body 10 to ensure that the entire corner area can withstand the pressure of the drag chain 30. The first arc plate 221, the second arc plate 222, and the second connecting plate 223 define a transition groove segment 224. A second roller assembly 225 is spaced apart in the transition groove segment 224. The length of the second roller assembly 225 gradually decreases from the third segment 23 toward the first segment 21.

[0052] The curvature of the first arc plate 221 and the second arc plate 222 is calculated to form a natural transition curvature, perfectly matching the turning path of the cable chain 30 and reducing the friction when the cable chain 30 turns. The second connecting plate 223 is similar to the first connecting plate 213, but with a slightly different shape, and the second connecting plate 223 is adapted to the arc structure. The transition groove section 224 formed by the first arc plate 221, the second arc plate 222, and the second connecting plate 223 ensures that the cable chain 30 does not disengage from the transition groove section 224 when turning, ensuring smooth movement and safety.

[0053] It should be noted that the gradually changing length of the second roller assembly 225, in conjunction with the arc plate, can effectively reduce the friction between the drag chain 30 and the transition groove section 224, avoid additional energy loss, and improve the overall efficiency of the system.

[0054] See Figure 2 and Figure 3 In some embodiments of this utility model, a second gap 226 is formed between two adjacent second roller assemblies 225, and between each second roller assembly 225 and the adjacent second connecting plate 223. The function of the second gap 226 is the same as that of the first gap 216 mentioned above. The second gap 226 facilitates the discharge of mud and other impurities that fall into the transition trough section 224.

[0055] When the drag chain 30 runs and drives the second roller assembly 225 to rotate, the mud, dust or other small impurities it carries will be carried to the second gap 226 and fall to the ground from the second gap 226, which facilitates the cleaning of impurities in the transition trough section 224.

[0056] See Figure 2 and Figure 3In some embodiments of this utility model, the third segment 23 includes a third baffle 231 and a fourth baffle 232 arranged opposite to each other. The third baffle 231 and the fourth baffle 232 provide physical barriers to prevent the drag chain 30 from derailing due to inertia or external force during operation. A third connecting plate 233 is connected between the third baffle 231 and the fourth baffle 232. Part of the third connecting plate 233 extends out of the third baffle 231 or the fourth baffle 232 and is connected to the track body 10, which strengthens the connection between the baffle and the track body and enhances the stability of the overall structure.

[0057] The third baffle 231, the fourth baffle 232 and the third connecting plate 233 restrict the storage slot section 234. The storage slot section 234 is provided with a third roller assembly 235 at intervals. The third roller assembly 235 is staggered with the third connecting plate 233. The length of each third roller assembly 235 is equal and the length of the third roller assembly 235 is greater than the length of the first roller assembly 215.

[0058] Essentially, the space enclosed by the third baffle 231, the fourth baffle 232, and the third connecting plate 233 serves not only as an ideal storage location for the cable chain 30 but also as the final destination during its retraction phase. This spacious design allows for neat storage of the cable chain 30, reducing stress concentration at the terminal position and extending its service life. Compared to the roller assemblies of the first and second segments 22, the third roller assembly 235 uses the same length specifications, ensuring consistent support for the cable chain 30 regardless of its position. This consistent design helps balance the load on the cable chain 30 at the terminal, preventing excessive localized wear.

[0059] See Figure 2 and Figure 3 In some embodiments of this utility model, a third gap 236 is formed between two adjacent third roller assemblies 235, and between each third roller assembly 235 and the adjacent third connecting plate 233. The third gap 236 has the same function as the first gap 216 and the second gap 226 mentioned above, which facilitates the discharge of mud and other impurities that fall into the storage tank section 234.

[0060] When the drag chain 30 runs and drives the second roller assembly 225 to rotate, the mud, dust or other small impurities it carries will be carried to the second gap 226 and fall to the ground from the second gap 226, which facilitates the cleaning of impurities in the transition trough section 224.

[0061] See Figure 2 and Figure 3In some embodiments of this utility model, the upper edge of the first baffle 211 or the second baffle 212 away from the track body 10 is provided with a first flange 217 extending outward; the upper edge of the first arc plate 221 or the second arc plate 222 away from the track body 10 is provided with a second flange 227 extending outward, and the second flange 227 is connected to the first flange 217; the upper edge of the third baffle 231 or the fourth baffle 232 away from the track body 10 is provided with a third flange 237 extending inward.

[0062] The first flange 217 is located on the top of the first baffle 211 or the second baffle 212 facing away from the track body 10, and folds outward to form an edge reinforcement structure. The second flange 227 is located on the top of the first arc plate 221 or the second arc plate 222 facing away from the track body 10, and folds outward to form an edge reinforcement structure. The main purpose of the first flange 217 and the second flange 227 is to increase the strength of the baffle and the arc plate and avoid breakage or deformation caused by continuous stress.

[0063] The third flange 237 is located above the third baffle 231 or the fourth baffle 232 that is away from the track body 10. The third flange 237 bends inward to ensure that the drag chain 30 will not accidentally jump out of the track boundary during storage, while also enhancing the structural stability of the baffle itself.

[0064] Figure 4 This is a cross-sectional view of the roller assembly in the track assembly provided in this embodiment of the utility model.

[0065] See Figure 4 In some embodiments of this utility model, the roller assembly includes a roller shaft 2351, a roller 2352 and a fastening component 2353. The roller shaft 2351 is fixed to the corresponding segment, the roller 2352 is sleeved on the outside of the roller shaft 2351, and the fastening component 2353 is adapted to fix the roller shaft 2351.

[0066] One end of the roller 2351 is fixed to a specific segment, while the other end is tightly connected to the roller 2352, serving as both support and connection. The roller 2352 is fitted around the roller 2351 and is the part that directly contacts the cable chain 30. The roller 2352 can be made of different materials, such as plastic, rubber, metal, or even composite materials, depending on the usage environment, to achieve optimal wear resistance and lightweight performance. In this invention, the roller 2352 is made of polyurethane, which effectively reduces friction between the cable chain and the cable chain groove, reduces cable chain wear, and improves cable chain life.

[0067] The fastening component 2353 is used to ensure that the roller shaft 2351 and the roller 2352 are firmly connected to prevent them from loosening under high-speed rotation or vibration. The fastening component 2353 can be a limit nut, or a fastening method in which the fastening component 2353 cooperates with a limit pin.

[0068] This utility model also provides a drilling platform robot, which includes a drag chain 30, a moving trolley 40 and the aforementioned track assembly. The track assembly is fixed on the drilling platform, the moving trolley 40 is adapted to move along a preset path of the track assembly, the robot assembly is adapted to be installed on the moving trolley 40, and the drag chain 30 is adapted to move along the drag chain groove 20.

[0069] The drilling platform robot is an automated device used at the wellhead. When it is necessary to move the drill pipe, the trolley 40 moves on the track assembly on the drilling platform and drives the robot assembly to move. When the robot assembly moves to the drill pipe position, the robot assembly begins to extend and approach the drill pipe, then clamps the drill pipe and moves again to switch the position of the drill pipe.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
