Detailed Implementation

[0044] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0045] It should be noted that in the description of this invention, "connection" should be interpreted broadly, and can be understood as a direct connection between the two or an indirect connection achieved through other components.

[0046] Figure 1 This is a three-dimensional structural diagram of the first type of assembled cable laying device 11 provided in this embodiment. Figures 2-8 This is a structural schematic diagram of the various connectors 210 provided in this embodiment. Please refer to the attached diagram. Figures 1-8 Embodiments of the present invention provide a modular cable laying device 10, which includes guide wheels 100 and a support frame 200. The guide wheels 100 are mounted on the support frame 200 and are used to guide the cable. The support frame 200 includes a plurality of connecting rods 220 and a plurality of connectors 210. The plurality of connecting rods 220 and the plurality of connectors 210 are spliced ​​together to form the support frame 200. Specifically, adjacent connectors 210 are detachably connected by connecting rods 220. The modular support frame 200 thus formed can be spliced ​​and adjusted according to requirements. At the same time, when the modular cable laying device 10 is not needed, the support frame 200 can be disassembled into a plurality of small parts (i.e., a plurality of connecting rods 220 and a plurality of connectors 210) for easy storage and transportation.

[0047] The connector 210 has at least two connecting portions 218 to connect at least two components (e.g., connecting rods 220). The connecting rods 220 are rigid members, and the middle portion of the connecting rod 220 connecting two adjacent connectors 210 can be located outside the connector 210 or entirely within the other two connectors 210, meaning the connecting rod 220 is not directly visible. The connector 210 can be configured in various ways to allow for more assembly options and flexibility in the structure of the support frame 200. Furthermore, all components connected via the connector 210 are detachably connected.

[0048] Optionally, in this embodiment, the connector 210 includes a straight connector 211, a 90° elbow connector 212, a 135° elbow connector 214, a horizontal three-way connector 215, a vertical three-way connector 216, and a four-way connector 217. Multiple connectors of each type can be used to assemble a suitable support frame 200 according to the user's needs. Obviously, in other embodiments, some of the above-mentioned connectors 210 can be selected according to the structure of the required support frame 200, or connectors with other structures can also be used.

[0049] The structure of the direct head 211 is as follows Figure 2 As shown, it is roughly cylindrical, with its two axial ends used for connecting to other components. That is, the direct head 211 has two connecting parts 218, and the two components connected by the direct head 211 are located on the same straight line.

[0050] The structure of the 90° elbow joint 212 is as follows Figure 3 As shown, it is roughly L-shaped, with its two free ends, that is, the ends of the two straight segments that make up the L-shape that are not connected, serving as connecting parts 218. Specifically, the 90° elbow 212 has two connecting parts 218, and the two components connected by the 90° elbow 212 are distributed at a 90° angle. A certain degree of error is allowed within this 90° angle, for example, within 5°.

[0051] The structure of the 135° elbow joint 214 is as follows: Figure 4 As shown, it has two connecting parts 218, and the extending directions of the two connecting parts 218 are set at a 135° angle. Correspondingly, the two components connected by the 135° elbow 214 are distributed at a 135° angle. The 135° angle here is allowed to have a certain error, for example, the error range is within 5°.

[0052] The structure of the horizontal three-joint 215 is as follows: Figure 5As shown, it has three connecting parts 218, any two of which are located in the same horizontal plane and form an angle of 90° between them. The axes of the three connecting parts 218 along their own extending directions intersect at a point. Correspondingly, the three components connected by the horizontal three-joint 215 form an angle of 90° between each pair. It is understood that in other embodiments, the angle between the two can also be set as needed, for example, 60°.

[0053] The structure of the vertical three-joint 216 is as follows: Figure 6 As shown, it has three connecting parts 218, two of which are located on the same straight line, and the remaining connecting part 218 is distributed at a 90° angle to the two above, thus forming a T-shaped structure. The three components connected by the vertical three-joint 216 are distributed in a T-shape.

[0054] As the name suggests, the four-connector 217 has four connecting parts 218, and its structure can be as follows: Figure 7 The structure shown is as follows: Figure 7 In the four-joint 217 shown, two connecting parts 218 are arranged vertically and on the same straight line, while the remaining two connecting parts 218 are located in the middle and are arranged at a 90° angle to each other. Figure 7 The four-connector 217 shown can be viewed as a structure with an additional connecting part 218 added to the middle of the vertical three-connector 216. Understandably, the positions of the four connecting parts 218 in the four-connector 217 can be adjusted according to requirements, for example, the four connecting parts 218 can be located on the same plane, or three of them can be located on the same plane.

[0055] Meanwhile, the structure of the connecting part 218 includes, but is not limited to, components (such as guide wheel 100 and connecting rod 220) that are connected to the connector 210 via insertion slots, thereby achieving a detachable connection with the connector 210. Specifically, at least two insertion slots within a connector 210 are interconnected; for example, the connector 210 may be a structure similar to a pipe fitting.

[0056] The modular cable laying device 10 also includes a fixing clamp 400, which is detachably mounted on the support frame 200. The fixing clamp 400 is used to clamp and fix the modular cable laying device 10 to the external structure to position it and prevent the device from moving out of its original position due to cable stress during the laying process. Specifically, the structure of the fixing clamp 400 can be as follows: Figure 8The structure shown has a snap-fit ​​groove 411 and a locking member 412. During fixing, an external structure, such as the edge of a cable tray, is inserted into the snap-fit ​​groove 411. Then, the locking member 412 is rotated via the handwheel 413 to lock the edge of the cable tray between the wall of the snap-fit ​​groove 411 and the locking member 412, thus fixing the modular cable laying device 10. The fixing clamp 400 also has a connecting rod, which is inserted into the connecting part 218 of a connector 210, allowing the fixing clamp 400 to be detachably installed on the support frame 200.

[0057] Figure 9 This is a top view of the first type of assembled cable laying device 11 provided in this embodiment. Figure 1 and Figure 9 The structure of the first type of modular cable laying device 11 provided in this embodiment is shown. The support frame 200 of the first type of modular cable laying device 11 includes a first frame 231 and a second frame 232. The first frame 231 and the second frame 232 are respectively spliced ​​together by multiple connecting rods 220 and multiple connectors 210. The first frame 231 and the second frame 232 are respectively located on both sides of the axial direction of the guide wheel 100 to achieve horizontal support of the guide wheel 100, that is, the axis of the guide wheel 100 extends horizontally, thereby guiding the cable to be transported horizontally in a straight line. Figure 1 and Figure 9 In the first type of modular cable laying device 11 shown, the first frame 231 and the second frame 232 have roughly the same structure. Both are connected to two support legs 233 via a horizontal three-way connector 215. The ends of the two support legs 233 away from the horizontal three-way connector 215 are supported by an external structure. The support legs 233 are formed by splicing together a connecting rod 220, a 135° elbow 214, and a 90° elbow 212.

[0058] Furthermore, the modular cable laying device 10 also includes a movable bending rod 300, the structure of which is as follows: Figure 10 and Figure 11 As shown, it has two hinged rod segments 311, so that the two ends of the movable bending rod 300 can be bent relative to each other. When the two components are respectively connected to the two ends of the movable bending rod 300, the two components can rotate relative to each other.

[0059] In such Figure 1 and Figure 9 In the first type of modular cable laying device 11 shown, the first frame 231 is connected to the guide wheel 100 via a movable bending rod 300, so that the guide wheel 100 and the second frame 232 connected to the guide wheel 100 can rotate relative to the first frame 231. Specifically, the movable bending rod 300 can be directly connected to the guide wheel 100, or the movable bending rod 300 can be configured to connect to the guide wheel 100 using a direct head 211.

[0060] The support leg 233 of the first frame 231 is detachably connected to a fixing clamp 400 at the end away from the horizontal three-way connector 215. That is, the first type of assembled cable laying device 11 has two fixing clamps 400. Both fixing clamps 400 are used to clamp and fix with the external structure, thereby realizing the positioning of the assembled cable laying device 10. In one embodiment, the external structure is a cable tray (not shown in the figure). The fixing clamp 400 clamps and fixes at the edge of the cable tray, thereby realizing the fixation of the assembled cable laying device 10 on the cable tray.

[0061] The second frame 232 has a support leg 233 that is detachably mounted on the end away from the horizontal three-joint 215 with a fixed tray 500 (structure as follows). Figure 12 As shown), the second frame 232 is supported on the outer base surface by the fixed tray 500. In one embodiment, the outer base surface is the inner bottom surface of the cable tray. The first type of assembled cable laying device 11 has two fixed trays 500. During the cable laying process, the fixed clamp 400 in the assembled cable laying device 10 clamps and fixes the cable tray at the edge, and the fixed tray 500 supports the inner bottom surface of the cable tray. After the cable is in place, the movable bending rod 300 between the first frame 231 and the guide wheel 100 drives the guide wheel 100 and the second frame 232 to rotate upward relative to the first frame 231. As a result, an opening appears between the second frame 232 and the inner bottom surface of the cable tray, allowing the cable to be transferred to the lower side of the support frame 200 inside the cable tray. At this time, the cable located on the upper side of the guide wheel 100 can be transferred to the cable tray without disassembling the assembled cable laying device 10 as a whole, thus completing the cable laying. Optionally, the fixed tray 500 is connected to the support leg 233 via a movable bending rod 300, and the two rod portions 311 of the movable bending rod 300 are respectively inserted into the connectors 210 at the ends of the fixed tray 500 and the support leg 233.

[0062] The structure of the modular cable laying device 10 is not limited to the first type of modular cable laying device 11 described above. It can be configured using different splicing methods of the support frame 200 to create structures suitable for other laying locations or usage scenarios. As an example, Figure 13 This illustration shows the three-dimensional structure of the second type of assembled cable laying device 12 provided in an embodiment of the present invention. Figure 14 A top view of the second type of assembled cable laying device 12 is shown. Figure 13 and Figure 14 As shown, the support frame 200 of the second type of assembled cable laying device 12 includes connectors 210 connected to both sides of the guide wheel 100 in the axial direction and two uprights 240. The two uprights 240 are formed by splicing together multiple connectors 210 and multiple connecting rods 220.

[0063] The support frame 240 can be a structure with a first connecting arm 241 and a second connecting arm 244 that are interconnected. The first connecting arm 241 is L-shaped and has a horizontal portion 242 and a vertical portion 243 that are interconnected, connected by a 90° elbow 212. One end of the horizontal portion 242 is connected to the guide wheel 100 via a horizontal three-way connector 215, and one end of the vertical portion 243 is connected to the second connecting arm 244. The second connecting arm 244 is a straight structure, with its end away from the first connecting arm 241 connected to the other axial end of the guide wheel 100 via a horizontal three-way connector 215. Thus, the support frame 240 and the guide wheel 100 form a quadrilateral frame structure, and the planes containing the two support frames 240 form an angle, specifically, the angle between the two support frames 240 is 90°. The guide rollers 100 are vertically supported by two uprights 240. The guide rollers 100 can be used to guide the cable to turn in the horizontal plane, that is, the second type of assembled cable laying device 12 is a 90° horizontal bend cable laying device. It should be noted that, in the description of this embodiment, the "plane where the uprights 240 are located" is the vertical plane of the quadrilateral formed by the axes of the uprights 240 and the guide rollers 100.

[0064] The support frame 240 also includes a fixing clamp 400 disposed at the connection between the first connecting arm 241 and the second connecting arm 244. In this embodiment, the two supports 240 have the same structure and are both provided with fixing clamps 400. Thus, the second type of assembled cable laying device 12 is fixed on the cable tray by the two fixing clamps 400.

[0065] Specifically, the first connecting arm 241 and the second connecting arm 244 are connected by a vertical three-joint 216. The remaining connecting part 218 of the vertical three-joint 216 is connected to the fixing clamp 400, and after connection, the fixing clamp 400 and the vertical part of the first connecting arm 241 are on the same straight line.

[0066] The second type of assembled cable laying device 12 also includes a cable tray 600, which has a blocking part 611 extending along the axial direction of the guide wheel 100. The blocking part 611 is located radially outside the outer peripheral surface of the guide wheel 100 to limit the cable between the blocking part 611 and the outer peripheral surface, thereby preventing the cable inside the wheel from slipping and getting stuck at the bend due to force. This also avoids the problem of damage to the cable or other components caused by the failure to detect the cable slippage in time, and correspondingly reduces the required manpower.

[0067] Figure 15 A three-dimensional structural diagram of the cable tray 600 is shown. Figure 16 A side view diagram of the cable tray 600 is shown. (As shown) Figure 14 and Figure 15As shown, the cable tray 600 has a generally fan-shaped tray body 612, and a blocking portion 611 is provided at the arc edge of the fan-shaped tray body 612 and extends upward along the axis of the tray body 612 (e.g., Figure 16 (As shown in the viewpoint) Extending convex structure. Figure 13 and Figure 14 As shown, the cable tray 600 is mounted on the lower side of the guide wheel 100, and the guide wheel 100 is coaxially arranged. The radial dimension of the tray body 612 is larger than the radial dimension of the guide wheel 100. Therefore, the arc-shaped edge of the cable tray 600 is located radially outside the guide wheel 100, and correspondingly, the blocking part 611 is located radially outside the guide wheel 100. At the same time, the tray body 612 cooperates with the lower end of the guide wheel 100 to support the cable and prevent the cable from detaching from the guide wheel 100.

[0068] As an example, Figure 17 This diagram shows a three-dimensional structural view of the third type of assembled cable laying device 13 provided in an embodiment of the present invention. Figure 18 The lateral structure of the third type of assembled cable laying device 13 is shown. Figure 19 The diagram shows a top view of the third type of modular cable laying device 13. (Example) Figures 17-19 As shown, the support frame 200 of the third type of modular cable laying device 13 has two side frames 251 arranged opposite each other and a connecting frame 254 arranged between the two side frames 251, thus forming a frame-type support structure. Both the side frames 251 and the connecting frame 254 are detachably assembled using connectors 210 and connecting rods 220. The connecting frame 254 is connected to the side frames 251 via horizontal three-way connectors 215 or four-way connectors 217.

[0069] The third type of assembled cable laying device 13 may include multiple guide wheels 100, which are arranged sequentially between two side frames 251, and the axial ends of the multiple guide wheels 100 are detachably connected to the two side frames 251 respectively.

[0070] The side frame 251 is roughly L-shaped, and its outer contour is a polygonal structure formed by multiple sides. Specifically, the side frame 251 has interconnected horizontal portions 252 and bending portions 253. A portion of the multiple guide wheels 100 are connected to the horizontal portion 252, and another portion is connected to the bending portion 253. The guide wheels 100 connected to the bending portion 253 are lower than the guide wheels 100 connected to the horizontal portion 252. Thus, the multiple guide wheels 100 guide the cable to turn in the vertical plane. In other words, this third type of assembled cable laying device 13 is a 90° downward bend cable laying device. Obviously, there is no limitation on the turning angle during cable laying. In other embodiments, the setting angle of the horizontal portion 252 relative to the bending portion 253 can be adjusted as needed to adjust the distribution of the guide wheels 100, for example, a 45° downward bend.

[0071] In such Figures 17-19 In the third type of assembled cable laying device 13 shown, there are three guide wheels 100, two of which are along the horizontal direction (i.e., Figure 19 The guide wheel 100 is distributed between the horizontal portions 252 of the two side frames 251 in the left-right direction, and the axis of the guide wheel 100 extends along the distribution direction of the two side frames 251. At the same time, the two ends of the guide wheel 100 are connected to the two side frames 251 respectively. Another guide wheel 100 is distributed between the bent portions 253 of the two side frames 251.

[0072] The third type of assembled cable laying device 13 also includes a fixed clamp 400 and a movable bending rod 300. The fixed clamp 400 is detachably connected to a side frame 251 via the movable bending rod 300. Thus, when the fixed clamp 400 is clamped and fixed to the edge of the cable tray, the bending of the movable bending rod 300 can drive the support frame 200 and the multiple guide wheels 100 mounted on the support frame 200 to rotate synchronously relative to the fixed clamp 400, which helps to transfer the cable located on the upper side of the guide wheels 100 into the cable tray.

[0073] Specifically, the two side frames 251 are the first side frame 251 and the second side frame 251, respectively. The horizontal part 252 of the first side frame 251 is provided with a four-joint 217 connected to the guide wheel 100. The four connecting parts 218 of the four-joint 217 are located in the same plane. At the same time, the upper and lower connecting parts 218 are respectively connected to the upper and lower parts that form the outline of the horizontal part 252 of the first side frame 251. The other two connecting parts 218 are respectively connected to the guide wheel 100 and the movable bending rod 300. The other end of the movable bending rod 300 is connected to the fixing clamp 400. In this third type of assembled cable laying device 13, there are two fixing clamps 400. Both fixing clamps 400 are installed on the horizontal part 252 of the first side frame 251 and are respectively connected to the two guide wheels 100 there through the four-joint 217.

[0074] The assembled cable laying device 10 provided in the embodiments of the present invention has been experimentally applied in the TK-02 tank repair project of the Beihai LNG Branch of the National Pipeline Network Group. In this project, the total length of electrical and instrumentation cables was 56,102 m, of which 10,320 m were large-diameter cables, averaging 550 m per cable. The project used a cable laying machine to lay the large-diameter cables in two sections: one from the pipe gallery to the top of the tank. One person was stationed every 10 m for inspection (compared to one person every 2 meters in conventional methods). Personnel were largely hands-on, only needing to check if the cables had fallen off the guide rollers 100 and coordinate the overall conveying rhythm. All cables were laid on the guide rollers 100 of the assembled cable laying device 10 by the cable laying machine. Only manual guidance was required at the cable start and end points, reducing labor costs. This was particularly crucial for laying large-diameter cables in vertical sections, and the final project time was 15 days, with all cables laid in place, significantly shortening the overall project duration.

[0075] The above examples provide several structures of the assembled cable laying device 10. Obviously, the structure of the assembled cable laying device 10 is not limited to these. In actual use, the cable laying needs of different locations and functions can be met by disassembling and reassembling the device and selectively assembling and using each component. That is, based on the structure of the support frame 200 formed by splicing assembly disclosed in this invention, any changes or substitutions that can be easily conceived by those skilled in the art should be covered within the protection scope of this invention.
