DETAILED DESCRIPTION

[0043] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the various 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.

[0044] It should be noted that, in the description of the present invention, “connection” should be understood in a broad sense, which can be understood as a direct connection between the two, or an indirect connection achieved through other components.

[0045] Figure 1 This is a schematic diagram of the three-dimensional structure of the first assembled cable laying device 11 provided in this embodiment. Figure 2-Figure 8 This is a schematic diagram of the structure of various connectors 210 provided in this embodiment. Figures 1-8 An embodiment of the present invention provides an assembled cable laying device 10, which includes a guide wheel 100 and a support frame 200. The guide wheel 100 is installed on the support frame 200 and is used to guide the cable. The support frame 200 includes a plurality of connecting rods 220 and a plurality of connecting heads 210. The plurality of connecting rods 220 and the plurality of connecting heads 210 are spliced ​​with each other to form the support frame 200. Specifically, adjacent connecting heads 210 are detachably connected by the connecting rods 220. The structure of the building block support frame 200 formed in this way can be spliced ​​and adjusted according to needs. At the same time, when the assembled cable laying device 10 is not needed, the support frame 200 can be disassembled into a plurality of small components (i.e., a plurality of connecting rods 220 and a plurality of connecting heads 210) for easy storage and transportation.

[0046] The connector 210 has at least two connecting portions 218 to connect at least two components (e.g., a connecting rod 220) through the connecting portions 218. The connecting rod 220 is a rigid rod, and the middle portion of the connecting rod 220 connecting two adjacent connectors 210 can be located outside the connector 210, or the entire portion can be located inside the other two connectors 210, i.e., in this case, the connecting rod 220 cannot be directly observed from the outside. The connector 210 can be set to a variety of structures to allow the structure of the support frame 200 to have more splicing methods and room for development. At the same time, the components connected by the connector 210 are all detachably connected.

[0047] Optionally, in this embodiment, the connectors 210 include a straight connector 211, a 90° elbow connector 212, a 135° elbow connector 214, a horizontal three-joint connector 215, a vertical three-joint connector 216, and a four-joint connector 217. There may be multiple connectors of each type 210 so that a suitable support frame 200 can be assembled according to the user's needs. Obviously, in other embodiments, some of the above-mentioned connectors 210 may be selected according to the structure of the support frame 200 to be assembled, or connectors 210 of other structures may be used.

[0048] The structure of the direct connector 211 is as follows: Figure 2 As shown, it is roughly cylindrical, and its two axial ends are used to connect with other components respectively, that is, the direct connector 211 has two connecting parts 218, and the two components connected by the direct connector 211 are located on the same straight line.

[0049] The structure of the 90° elbow 212 is as follows Figure 3 As shown, it is generally L-shaped, with its two free ends, i.e., the ends not connected to the two straight segments forming the L-shape, forming connecting portions 218. In other words, the 90° elbow 212 has two connecting portions 218, and the two components connected by the 90° elbow 212 are distributed at a 90° angle. The 90° angle here is allowed to have a certain error, for example, within a range of 5°.

[0050] The structure of the 135° elbow 214 is as follows Figure 4 As shown, it has two connecting portions 218, and the extension directions of the two connecting portions 218 are arranged at a 135° angle. Accordingly, the two components connected by the 135° elbow 214 are distributed at a 135° angle. The 135° angle here allows a certain error, for example, the error range is within 5°.

[0051] The structure of the horizontal three-joint 215 is as follows Figure 5As shown, it has three connecting portions 218. Any two of the three connecting portions 218 are located in the same horizontal plane, and the angle between them is 90°. The axes of the three connecting portions 218 along their own extension directions intersect at a point. Accordingly, the angle between the three components connected by the horizontal three-joint 215 is 90°. It is understood that in other embodiments, the angle between the two components can also be set as required, for example, 60°.

[0052] 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 an angle of 90° to the above two, thus forming a structure with a T-shaped cross-section, and the three components connected by the vertical three-joint 216 are distributed in a T-shape.

[0053] As the name implies, the four-joint 217 has four connecting parts 218, and its structure can be as follows: Figure 7 The structure shown, such as Figure 7 Two of the four connectors 217 are arranged vertically and on the same straight line, and the remaining two connectors 218 are located in the middle and form a 90° angle between each other. Figure 7 The four-joint 217 shown can be viewed as a structure with a connecting portion 218 added to the middle portion of the vertical three-joint 216. It is understood that the positions of the four connecting portions 218 in the four-joint 217 can be adjusted as needed, for example, all four connecting portions 218 are located on the same plane, or three of them are located on the same plane.

[0054] Meanwhile, the structure of the connecting portion 218 includes, but is not limited to, a plug-in slot, and components connected to the connector 210 (e.g., the guide wheel 100 and the connecting rod 220) are plugged into the plug-in slot to achieve a detachable connection with the connector 210. Specifically, at least two plug-in slots in a connector 210 are interconnected. For example, the connector 210 can have a structure similar to a pipe joint.

[0055] The assembled cable laying device 10 further includes a fixing fixture 400, which is detachably mounted on the support frame 200 and is used to clamp and fix to an external structure to position the assembled cable laying device 10, thereby preventing the laying device from being displaced from its original position due to force applied to the cable during the laying process. Specifically, the structure of the fixing fixture 400 can be as follows: Figure 8The structure shown has a snap-in slot 411 and a locking member 412. When securing, an external structure, such as a bridge edge, is inserted into the snap-in slot 411. The locking member 412 is then rotated using a handwheel 413 to lock the bridge edge between the wall of the snap-in slot 411 and the locking member 412, thereby securing the assembled cable laying device 10. The fixing fixture 400 also has a connecting rod that is plugged into a connecting portion 218 of a connector 210, enabling the fixing fixture 400 to be removably mounted on the support frame 200.

[0056] Figure 9 This is a schematic diagram of the top view of the first assembled cable laying device 11 provided in this embodiment. Figure 1 and Figure 9 The structure of the first assembled cable laying device 11 provided in this embodiment is shown. The support frame 200 of the first assembled 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 formed by splicing multiple connecting rods 220 and multiple connecting heads 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 horizontal and linear transportation of the cable. Figure 1 and Figure 9 In the first assembled cable laying device 11 shown, the first frame 231 and the second frame 232 have substantially the same structure, each connected via a horizontal three-way joint 215 to two legs 233. The legs 233 are supported by an external structure at one end away from the horizontal three-way joint 215. The legs 233 are formed by connecting rods 220, 135° elbow joints 214, and 90° elbow joints 212.

[0057] Furthermore, the assembled cable laying device 10 further includes a movable bending rod 300, the structure of which is as follows: Figure 10 and Figure 11 As shown, it has two mutually hinged rod sections 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.

[0058] In such Figure 1 and Figure 9 In the first assembled 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 connector 211.

[0059] The leg 233 of the first frame 231 is detachably connected to a fixing clamp 400 at one end away from the horizontal three-joint 215, that is, the first assembled cable laying device 11 has two fixing clamps 400, and 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 bridge (not shown in the figure), and the fixing clamps 400 are clamped and fixed at the edge of the bridge, thereby realizing the fixation of the assembled cable laying device 10 on the bridge.

[0060] The end of the support leg 233 of the second frame 232 away from the horizontal three-joint 215 is detachably mounted with a fixed tray 500 (structure as shown in FIG. Figure 12 As shown), the second frame 232 is supported on the external base surface by the fixed tray 500. In one embodiment, the external base surface is the inner bottom surface of the bridge. The first assembled cable laying device 11 has two fixed trays 500. During the cable laying process, the fixed fixture 400 in the assembled cable laying device 10 is clamped and fixed at the edge of the bridge, and the fixed tray 500 is supported on the inner bottom surface of the bridge. 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, so that an opening for transferring the cable to the lower side of the support frame 200 inside the bridge appears between the second frame 232 and the inner bottom surface of the bridge. At this time, the cable located on the upper side of the guide wheel 100 can be transferred to the bridge without disassembling the assembled cable laying device 10 as a whole, thereby 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 plugged into the fixed tray 500 and the connector 210 at the end of the support leg 233 respectively.

[0061] The structure of the assembled cable laying device 10 is not limited to the first assembled cable laying device 11 provided above, and it can be formed into a structure suitable for other laying locations or usage scenarios by different splicing methods of the support frame 200. As an example, Figure 13 FIG. 1 shows the three-dimensional structure of a second assembled cable laying device 12 provided by an embodiment of the present invention. Figure 14 FIG. 1 shows a top view of the second assembled cable laying device 12. Figure 13 and Figure 14 As shown, the support frame 200 in the second assembled cable laying device 12 includes a connector 210 connected to the axial sides of the guide wheel 100 and two vertical frames 240. The two vertical frames 240 are formed by splicing multiple connectors 210 and multiple connecting rods 220 respectively.

[0062] The vertical frame 240 may be a structure having a first connecting arm 241 and a second connecting arm 244 connected to each other. The first connecting arm 241 is L-shaped and has a horizontal portion 242 and a vertical portion 243 connected to each other. The horizontal portion 242 and the vertical portion 243 are connected by a 90° elbow 212. One end of the horizontal portion 242 is connected to the guide wheel 100 via a horizontal three-joint 215, and one end of the vertical portion 243 is connected to the second connecting arm 244. The second connecting arm 244 is a linear structure, and its end away from the first connecting arm 241 is connected to the other axial end of the guide wheel 100 via a horizontal three-joint 215. In this way, the vertical frame 240 and the guide wheel 100 form a quadrilateral frame structure, and the planes of the two vertical frames 240 form an angle. Specifically, the angle between the two vertical frames 240 is 90°. The guide wheel 100 is vertically supported by two uprights 240. The guide wheel 100 can be used to guide the cable to turn in a horizontal plane. In other words, the second assembled cable laying device 12 is a 90° horizontal elbow cable laying device. It should be noted that in the description of this embodiment, the "plane in which the uprights 240 are located" refers to the vertical plane in which the quadrilateral formed by the axes of the uprights 240 and the guide wheel 100 is located.

[0063] The stand 240 also includes a fixing clamp 400 arranged at the connection between the first connecting arm 241 and the second connecting arm 244. In this embodiment, the two stands 240 have the same structure and are both provided with a fixing clamp 400. In this way, the second assembled cable laying device 12 is fixed on the bridge frame through two fixing clamps 400.

[0064] Specifically, the first connecting arm 241 and the second connecting arm 244 are connected through the vertical three-joint 216, and the remaining connecting portion 218 of the vertical three-joint 216 is connected to the fixing fixture 400, and after the connection, the fixing fixture 400 and the vertical portion of the first connecting arm 241 are located on the same straight line.

[0065] The second assembled cable laying device 12 also includes a cable tray 600, which has a blocking portion 611 extending axially along the guide wheel 100, and the blocking portion 611 is located radially outside the outer peripheral surface of the guide wheel 100 to limit the cable between the blocking portion 611 and the outer peripheral surface, thereby avoiding the situation where the cable in the wheel slips due to force and gets stuck at the turn, thereby avoiding the problem of damage to the cable or other components due to untimely discovery after the cable slips, and accordingly reducing the required manpower allocation.

[0066] Figure 15 shows a three-dimensional structural diagram of a cable tray 600, Figure 16 FIG. 6 shows a side structural diagram of a cable tray 600. Figure 14 and Figure 15As shown, the cable tray 600 has a substantially fan-shaped tray body 612, and the blocking portion 611 is arranged at the arc edge of the fan-shaped tray body 612 and extends upward along the axis of the tray body 612 (as shown in FIG. Figure 16 The protruding structure extends from the viewing angle shown. Figure 13 and Figure 14 As shown, the cable tray 600 is mounted on the underside of the guide wheel 100, which is coaxially arranged with the guide wheel 100. The radial dimension of the tray 612 is larger than that of the guide wheel 100. Therefore, the arcuate edge of the cable tray 600 is located radially outward of the guide wheel 100. Correspondingly, the blocking portion 611 is located radially outward of the guide wheel 100. The tray 612 also cooperates with the lower end of the guide wheel 100 to support the cables and prevent them from falling off the guide wheel 100.

[0067] As an example, Figure 17 FIG. 1 shows a three-dimensional structural diagram of a third assembled cable laying device 13 provided by an embodiment of the present invention. Figure 18 The lateral structure of the third assembled cable laying device 13 is shown. Figure 19 FIG. 1 shows a top view of the third assembled cable laying device 13. Figure 17-Figure 19 As shown, the support frame 200 of the third modular cable laying device 13 comprises two opposing side frames 251 and a connecting frame 254 disposed between the side frames 251, thereby forming a frame-like support structure. The side frames 251 and the connecting frame 254 are detachably connected via connectors 210 and connecting rods 220. The connecting frame 254 is connected to the side frames 251 via three horizontal connectors 215 or four horizontal connectors 217.

[0068] The third assembled cable laying device 13 may include a plurality of guide wheels 100 , which are sequentially arranged between the two side frames 251 , and the axial ends of the plurality of guide wheels 100 are detachably connected to the two side frames 251 .

[0069] The side frame 251 is generally L-shaped, and its outer contour is a polygonal structure surrounded by multiple edges. Specifically, the side frame 251 has a horizontal portion 252 and a bent portion 253 connected to each other. Among the multiple guide wheels 100, some are connected to the horizontal portion 252, and the other portion is connected to the bent portion 253. The guide wheels 100 connected to the bent portion 253 are lower than the guide wheels 100 connected to the horizontal portion 252. In this way, the cables are guided to turn in a vertical plane through the multiple guide wheels 100. In other words, this third assembled cable laying device 13 is a 90° lower elbow cable laying device. Obviously, there is no restriction on the turning angle during cable laying. In other embodiments, the setting angle of the horizontal portion 252 relative to the bent portion 253 can also be adjusted as needed to adjust the distribution of the guide wheels 100, such as a 45° lower elbow.

[0070] In such Figure 17-Figure 19 In the third assembled cable laying device 13 shown, there are three guide wheels 100, two of which are arranged in the horizontal direction (ie Figure 19 The left and right directions of the guide wheel 100 are distributed between the horizontal parts 252 of the two side frames 251, and the axis of the guide wheel 100 extends along the distribution direction of the two side frames 251. At the same time, the axial ends of the guide wheel 100 are respectively connected to the two side frames 251; the other guide wheel 100 is distributed between the bending parts 253 of the two side frames 251.

[0071] The third 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 through the movable bending rod 300. In this way, when the fixed clamp 400 is clamped and fixed on the edge of the bridge frame, the bending of the movable bending rod 300 can drive the support frame 200 and the multiple guide wheels 100 installed 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 wheel 100 into the bridge frame.

[0072] Specifically, the two side frames 251 are respectively a first side frame 251 and a second side frame 251. The horizontal portion 252 of the first side frame 251 is provided with four joints 217 connected to the guide wheel 100. The four connecting portions 218 of the four joints 217 are located in the same plane. The upper and lower connecting portions 218 of the four joints 217 are respectively connected to the upper and lower portions of the contour of the horizontal portion 252 of the first side frame 251. The other two connecting portions 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 fixture 400. The number of fixing fixtures 400 in this third assembled cable laying device 13 is two. Both fixing fixtures 400 are installed on the horizontal portion 252 of the first side frame 251 and are respectively connected to the two guide wheels 100 there through the four joints 217.

[0073] The assembled cable laying device 10 provided by the embodiment of the present invention has been experimentally applied in the TK-02 tank repair project of the Beihai LNG branch of the National Energy Administration Group. In this project, a total of 56,102 meters of electrical and instrument cables were laid, of which 10,320 meters were large-diameter cables, with an average length of 550 meters per cable. The project used a cable laying machine to lay the large-diameter cables in two sections: the pipe corridor as one section, and the pipe corridor to the tank top as another section. On average, one person was assigned to conduct inspections every 10 meters (the conventional method uses one person every 2 meters for laying). The personnel basically did not need to do anything, but only needed to check whether the cables fell out of the guide wheel 100 and coordinate and control the overall transmission rhythm. All cables were mounted on the guide wheel 100 of the assembled cable laying device 10 and laid by the cable laying machine. Only manual guidance was required at the starting and ending points of the cables, reducing labor costs. It played a particularly important role in the laying of large-diameter cables in vertical sections, and the final construction period was 15 days. All cables were laid in place, greatly shortening the construction period.

[0074] The above provides several exemplary structures of the assembled cable laying device 10. Obviously, the structure of the assembled cable laying device 10 is not limited thereto. In actual use, the cable laying requirements of different positions and functions can be met by disassembling and reassembling the device and selectively assembling and using the components. That is, on the basis of the support frame 200 structure formed by splicing assembly disclosed in the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be covered within the scope of protection of the present invention.
