Description

Technical Field

[0001] This invention relates to the field of temporary cable installation technology, and more specifically, to a temporary cable installation device. Background Technology

[0002] Cables are used to transmit electricity, signal current, or signal voltage. A cable consists of a conductor covered with an insulation layer, a protective layer, and a shielding layer. Cables are classified into high-voltage cables and low-voltage cables according to voltage. Low-voltage cables consist of three parts: the conductor, the insulation layer, and the protective layer. The conductor is used to conduct current and is generally made of multiple strands of copper or aluminum wire twisted together. Low-voltage cables come in single-core, double-core, three-core, and four-core varieties. During the maintenance and repair of low-voltage lines, temporary installation devices are needed to re-erect cables that have fallen to the ground.

[0003] In related technologies, the temporary installation of cables typically relies on multiple struts to support the cables.

[0004] However, in practical applications, cables erected between two adjacent support poles often sag due to their own weight. This can not only damage the stability of the support poles and make them prone to tipping over, but also affect the stability and safety of the temporary cable installation.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 9As shown, this embodiment of the invention provides a temporary cable laying device, which includes a mounting frame 10, an extension frame 20, a cable support 30, and a driving component 40. The extension frame 20 is telescopically mounted on the mounting frame 10 in the lateral direction. The cable support 30 includes a plurality of sliding members 31 arranged in the lateral direction on the extension frame 20. The sliding members 31 are movably mounted relative to the extension frame 20 in the lateral direction. The cable support 30 has a retracted state and an extended state. When the cable support 30 is in the retracted state, the plurality of sliding members 31 are close to each other. When the cable support 30 is in the extended state, the plurality of sliding members 31 are far apart from each other to extend in the lateral direction. The driving component 40 is mounted on the mounting frame 10 and is drivenly connected to the extension frame 20 and the cable support 30 respectively. The driving component 40 can drive the extension frame 20 to extend and retract, and can also drive the cable support 30 to switch between the retracted state and the extended state.

[0035] The temporary cable laying device provided in this embodiment includes a mounting frame 10, an extension frame 20, a cable support 30, and a driving component 40. When temporarily laying the cable 50, the cable 50 is first hung on the cable support 30 in the retracted state. The driving component 40 drives the extension frame 20 to unfold in the lateral direction. Then, the driving component 40 drives the cable support 30 to switch to the unfolded state, so that multiple sliding components 31 unfold in the lateral direction. The multiple sliding components 31 are used to lay the cable 50 in the lateral direction, preventing the cable 50 laid in the lateral direction by the cable support 30 from falling due to its own weight, thereby improving the stability and safety of the temporary cable laying.

[0036] like Figures 1 to 4 , Figure 7 as well as Figure 9As shown, the cable support 30 also includes a connecting rope 32, a first reversing part 33, and a pull rope 34. The connecting rope 32 extends in the lateral direction and is connected to a plurality of sliding members 31 respectively. One end of the connecting rope 32 is fixedly connected to the starting end of the extension frame 20. When the cable support 30 is in the retracted state, the portion of the connecting rope 32 located between two adjacent sliding members 31 is folded. When the cable support 30 is in the unfolded state, the plurality of sliding members 31 are far apart from each other, and the portion of the connecting rope 32 located between two adjacent sliding members 31 is unfolded. The first reversing part 33 is located at the end of the extension frame 20. The pull rope 34 is wound around the first reversing part 33. The first end of the pull rope 34 is connected to one of the sliding members 31 located near the end. The driving member 40 can be driven to connect with the second end of the pull rope 34. When temporarily installing the cable 50, the cable 50 is first hung on the cable support 30 in the retracted state. The extension frame 20 is then driven by the drive unit 40 to unfold in the lateral direction, so that the end and the beginning of the extension frame 20 are far apart. Then, the pull rope 34 is wound up by the drive unit 40, so that the pull rope 34 pulls the sliding member 31 to unfold the part of the connecting rope 32 located between two adjacent sliding members 31, thereby unfolding multiple sliding members 31 in the lateral direction. The cable 50 is then installed in the lateral direction using multiple sliding members 31.

[0037] Specifically, the first reversing part 33 reverses the transmission direction of the pull rope 34, so that the force exerted by the driving member 40 on the second end of the pull rope 34 forms an angle with the force exerted by the first end of the pull rope 34 on the sliding member 31, facilitating flexible layout of the driving member 40. Furthermore, one end of the connecting rope 32 is fixedly connected to the starting end of the extension frame 20, so that when the pull rope 34 pulls the multiple sliding members 31 to unfold in the lateral direction, the connecting rope 32 and the multiple sliding members 31 form an unfolding effect with one end fixed.

[0038] like Figure 9 As shown, in this embodiment, one of the multiple sliders 31 located near the starting end is connected to the first reversing part 33 located at the starting end.

[0039] like Figures 1 to 4 as well as Figure 7As shown, the extension frame 20 includes a suspension assembly 22 and two extension rods 21. The two extension rods 21 are symmetrically arranged on the mounting frame 10 relative to the mounting frame 10. The extension direction of the extension rods 21 is parallel to the transverse direction. The starting end corresponds to the end of one extension rod 21 that is away from the mounting frame 10, and the ending end corresponds to the end of the other extension rod 21 that is away from the mounting frame 10. The suspension assembly 22 includes a suspension rope 221 and two second reversing parts 222. The two second reversing parts 222 are respectively arranged at the starting end and the ending end. The suspension rope 221 is sleeved on the two second reversing parts 222. The driving member 40 is drivenly connected to the extension rods 21 and the suspension rope 221 respectively to drive the extension rods 21 and the suspension rope 221 to extend or shorten simultaneously. A plurality of sliding members 31 are slidably sleeved on the suspension rope 221 along the extension direction of the suspension rope 221. The plurality of sliding members 31 are located between the two second reversing parts 222. During the process of using the drive member 40 to drive the extension frame 20 to extend in the lateral direction, the drive member 40 drives the extension rod 21 and the suspension rope 221 to extend simultaneously. Since the starting end is set to correspond to the end of one telescopic rod away from the mounting frame 10, and the ending end is set to correspond to the end of another telescopic rod away from the mounting frame 10, the ending end and the starting end are moved away from each other, and the two second reversing parts 222 are moved away from each other. The first reversing part 33 moves away from the starting end, thereby tightening the suspension rope 221. Then, the drive member 40 is used to wind up the pull rope 34, so that the pull rope 34 pulls the sliding member 31, so that multiple sliding members 31 are extended along the extension direction of the suspension rope 221, and the cable 50 is erected in the lateral direction using multiple sliding members 31.

[0040] The second reversing part 222 reverses the transmission direction of the suspension rope 221, so that the force exerted by the driving member 40 on the suspension rope 221 can be set at an angle with the part of the suspension rope 221 located between the two second reversing parts 222, which facilitates the flexible layout of the driving member 40.

[0041] Specifically, both the first reversing section 33 and the second reversing section 222 use fixed pulleys.

[0042] like Figures 1 to 7As shown, the drive unit 40 includes a drive motor 41, a winding reel 42, and a take-up reel 43. The drive motor 41 is mounted on the mounting frame 10. The winding reel 42 is rotatably mounted on the mounting frame 10. The suspension rope 221 is wound around the winding reel 42 and connected to it. The drive motor 41 is driven by both the winding reel 42 and the extension rod 21. The take-up reel 43 is rotatably mounted on the mounting frame 10. The second end of the pull rope 34 is wound around the take-up reel 43 and connected to it. The drive motor 41 is driven by the take-up reel 43. The drive unit 40 has a first transmission state and a second transmission state. When the drive unit 40 is in the first transmission state, the take-up reel 43 and the winding reel 42 simultaneously wind up or unwind the wire. When the drive unit 40 is in the second transmission state, the take-up reel 43 can independently wind up or unwind the wire relative to the winding reel 42. When the drive unit 40 is in the first transmission state, the drive motor 41 is started. The drive motor 41 drives the take-up reel 43 and the unwind reel 42 to unwind the line at the same time. At the same time, the drive motor 41 drives the extension rod 21 to extend. Thus, during the extension and relaxation of the pull rope 34 and the suspension rope 221, the extension rod 21 extends outward and drives the first reversing part 33 and the second reversing part 222 to move, so that the suspension rope 221 remains taut.

[0043] It should be noted that when the drive unit 40 is in the second transmission state, the take-up reel 43 can independently take up or unload the wire relative to the unwind reel 42, including:

[0044] (1) There is no transmission structure between the take-up reel 43 and the unwind reel 42, and the take-up reel 43 can rotate freely relative to the unwind reel 42;

[0045] (2) There is still a transmission structure between the take-up reel 43 and the unwind reel 42 so that the drive motor 41 drives the take-up reel 43 and the unwind reel 42 to rotate simultaneously, but the rotation directions of the take-up reel 43 and the unwind reel 42 are opposite.

[0046] Thus, the drive unit 40 is switched to the second transmission state, and the winding wheel 43 is used to wind up the pull rope 34. The pull rope 34 pulls the sliding member 31 to move, so that the multiple sliding members 31 are unfolded in the lateral direction. During the unfolding process, the multiple sliding members 31 lay the cable in a horizontal state.

[0047] like Figure 5 and Figure 6As shown, the take-up reel 43 has a splined shaft 431 and a drive handle 432. The drive member 40 has a first spline groove 421. When the drive member 40 is in the first transmission state, the splined shaft 431 is inserted into the first spline groove 421. When the drive member 40 is in the second transmission state, the splined shaft 431 is separated from the first spline groove 421. After the extension frame 20 is extended to the required length, the take-up reel 43 is pulled outward, separating the splined shaft 431 from the first spline groove 421. By operating the drive handle 432, the take-up reel 43 can be rotated independently to wind up the pull rope 34.

[0048] like Figure 5 and Figure 6 As shown, the drive unit 40 also includes a transmission assembly 44 disposed between the drive motor 41 and the extension rod 21. The transmission assembly 44 includes a transmission wheel 441, the rotation direction of the transmission wheel 441 is opposite to the rotation direction of the winding and unwinding wheel 42, and a second spline groove 4413 is provided on the transmission wheel 441. When the drive unit 40 is in the second transmission state, the spline shaft 431 is inserted into the second spline groove 4413. With the spline shaft 431 inserted into the second spline groove 4413, the drive motor 41 is started. The drive motor 41 drives the take-up wheel 43 to unload the cable, the drive motor 41 drives the extension rod 21 to extend, and the drive motor 41 drives the winding and unwinding wheel 42 to take in the cable. During the extension and relaxation of the suspension rope 221, the extension rod 21 extends outward to drive the second reversing part 222 to move, so that the suspension rope 221 remains taut and the first reversing part 33 and the second reversing part 222 at the end move synchronously. At the same time, the pull rope 34 is wound up, and the pull rope 34 pulls the sliding member 31 to move, so that the multiple sliding members 31 unfold in the lateral direction. During the unfolding process, the multiple sliding members 31 lay the cable in a horizontal state.

[0049] like Figure 3 , Figure 5 , Figure 6 as well as Figure 8As shown, the transmission wheel 441 includes a driving pulley 4411 and a driven pulley 4412. The driving pulley 4411 is rotatably mounted on the mounting frame 10. The drive motor 41 is driven and connected to the driving pulley 4411. The rotation direction of the driving pulley 4411 is opposite to the rotation direction of the winding and unwinding wheel 42. A second spline groove 4413 is provided on the driving pulley 4411. The driven pulley 4412 is rotatably mounted on the mounting frame 10. The driven pulley 4412 is driven and connected to the extension rod 21. The transmission assembly 44 also includes a transmission belt 442, which is sleeved on the driving pulley 4411 and the driven pulley 4412. The belt drive described above facilitates long-distance transmission. The driven pulley 4412 is positioned at a higher position along with the extension frame 20, while the drive motor 41, drive pulley 4411, and winding reel 43 are positioned at a lower position. This increases the height of the overhead line and makes it easier for personnel to inspect and operate the drive motor 41, drive pulley 4411, and winding reel 43 from the ground.

[0050] like Figure 5 and Figure 6 As shown, the drive unit 40 also includes a first gear 45, a second gear 46, a third gear 47, and a fourth gear 48. The drive motor 41 is connected to the first gear 45. A first spline groove 421 is disposed on the first gear 45. The second gear 46 is coaxially disposed with and connected to the drive pulley 4411, with the first gear 45 and second gear 46 meshing. The third gear 47 is coaxially disposed with and connected to the drive pulley 4411, and the fourth gear 48 is coaxially disposed with and connected to the unwinding pulley 42, with the third gear 47 and fourth gear 48 meshing. The use of the first gear 45, second gear 46, third gear 47, and fourth gear 48 for transmission ensures that the rotation directions of the first spline groove 421 and the second spline groove 4413 are opposite, and makes the transmission of the drive unit 40 reliable.

[0051] like Figure 2 and Figure 3As shown, the extension rod 21 includes a fixed rod 211, a movable rod 212, a first drive shaft 213, and a second drive shaft 214. The fixed rod 211, the movable rod 212, and the first drive shaft 213 all extend in the lateral direction. The fixed rod 211 is fixedly mounted on the mounting bracket 10. The movable rod 212 is movably mounted on the fixed rod 211 in the lateral direction. The first drive shaft 213 is rotatably mounted on the fixed rod 211 about its axis. The extension direction of the second drive shaft 214 is perpendicular to the lateral direction. The driven pulley 4412 is drivenly connected to the second drive shaft 214. The second drive shaft 214 is drivenly connected to the first drive shaft 213 to drive the first drive shaft 213 to rotate. The first drive shaft 213 is drivenly connected to the movable rod 212 to drive the movable rod 212 to move. Using the aforementioned extension rod 21, the driven pulley 4412 drives the second transmission shaft 214 to rotate coaxially, the second transmission shaft 214 drives the first transmission shaft 213 to rotate around the axis of the first transmission shaft 213, and the first transmission shaft 213 drives the movable rod 212 to move in the lateral direction.

[0052] like Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, the transmission assembly 44 also includes a worm 216 and a worm wheel 215. The worm 216 is coaxially arranged with the first transmission shaft 213 and the second transmission shaft 214. The worm 216 and the worm wheel 215 mesh with each other, so that the second transmission shaft 214 drives the first transmission shaft 213 to rotate through the worm 216 and the worm wheel 215.

[0053] Specifically, such as Figure 7 and Figure 8 As shown, the first drive shafts 213 of the two extension rods 21 are symmetrically arranged with respect to the mounting bracket 10, and the ends of the first drive shafts 213 of the two extension rods 21 facing the mounting bracket 10 are both connected to the same worm gear 215.

[0054] like Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, the extension rod 21 also includes a transmission block 217. The extension rod 21 includes two movable rods 212 arranged side by side. Both movable rods 212 are connected to the transmission block 217. The transmission block 217 is sleeved on the first transmission shaft 213 and is threadedly engaged with the first transmission shaft 213.

[0055] like Figures 1 to 4As shown, the extension frame 20 also includes an extension rod 23, the extension rod 23 extending in a direction perpendicular to the lateral direction, the middle part of the extension rod 23 being connected to one end of the extension rod 21 away from the mounting frame 10, the extension frame 20 including at least two suspension assemblies 22, the at least two suspension assemblies 22 being arranged along the extension rod 23, and the temporary cable laying device including at least two cable support members 30 corresponding to the at least two suspension assemblies 22, so that the temporary cable laying device can lay at least two cables 50.

[0056] like Figures 2 to 4 As shown, the extension frame 20 also includes a counterweight 24 and an I-beam tube 25. The counterweight 24 is detachably mounted on the extension rod 23. The counterweight 24 can be disassembled and assembled according to the number and distribution of cables 50 installed by the temporary cable installation device, balancing the force on the extension frame 20 and improving the stress stability of the mounting frame 10. The extension rod 23 has an insert 231. The I-beam tube 25 is connected to the end of the extension rod 21 facing away from the mounting frame 10. The insert 231 is detachably inserted into the I-beam tube 25 in the vertical direction for easy assembly and disassembly of the extension rod 23 and the extension rod 21.

[0057] like Figure 9 As shown, the sliding member 31 includes a sliding sleeve 311 and a hanging hook 312. The sliding sleeve 311 is slidably fitted onto the suspension rope 221, and the hanging hook 312 is located at the bottom of the sliding sleeve 311. The connecting rope 32 is connected to the hanging hook 312. When temporarily erecting the cable 50, the cable 50 is hung on the hanging hooks 312 of the multiple sliding members 31.

[0058] like Figure 9 As shown, the sliding member 31 also includes ball bearings 313. Ball bearings 313 are embedded in the inner wall of the sliding sleeve 311 and the mating surface of the hook 312 that contacts the cable 50.

[0059] like Figures 1 to 4 As shown, the mounting frame 10 includes a top base 11 and a telescopic frame 12. The telescopic frame 12 includes a telescopic upright 121 and multiple telescopic diagonal braces 122. The telescopic upright 121 is telescopically oriented in the vertical direction, and its upper end is connected to the top base 11. The upper ends of the multiple telescopic diagonal braces 122 are all hinged to the upper end of the telescopic upright 121. The telescopic diagonal braces 122 are inclined relative to the telescopic upright 121 and are telescopically oriented along their extension direction. The multiple telescopic diagonal braces 122 are arranged circumferentially along the telescopic upright 121. When temporarily erecting the cable 50 using the mounting frame 10 with the above structure, the telescopic frame 12 is first retracted to allow workers to hang the cable 50 on the cable support 30 in its retracted state from a lower height. Then, the telescopic upright 121 and the multiple telescopic diagonal braces 122 are extended to raise the cable 50 to the clamping height.

[0060] like Figures 1 to 6As shown, the mounting frame 10 also includes a mounting seat 13 disposed on the telescopic upright 121. The mounting frame 10 also includes multiple transmission rods disposed one-to-one with the multiple telescopic diagonal rods 122. The two ends of the transmission rods are respectively hinged to the mounting seat 13 and the telescopic diagonal rods 122. The mounting seat 13 includes a seat body and a fastener. The seat body is movably sleeved on the telescopic upright 121 along the extension direction of the telescopic upright 121. The fastener has a locked state and an adjustable state. When the fastener is in the locked state, the fastener restricts the movement of the seat body along the telescopic upright 121. When the fastener is in the adjustable state, the fastener allows the seat body to move along the telescopic upright 121. At the same time, the seat body drives the transmission rod to swing, thereby driving the telescopic diagonal rods 122 to swing.

[0061] Specifically, the drive motor 41 is mounted on the base, and the winding and unwinding wheel 42, the first gear 45, the second gear 46, the third gear 47, and the fourth gear 48 are rotatably mounted on the base.

[0062] like Figures 1 to 4 As shown, the lower end of the telescopic diagonal bar 122 is rotatably connected to a positioning plate 124 for connection with the ground via a ball joint. The lower end of the telescopic pole 121 is provided with a positioning plate 123. Both the positioning plate 124 and the positioning plate 123 are provided with grounding bolts. Before the telescopic pole 121 extends, the positioning plate 123 is fixed to the ground by the grounding bolts. Then, after the telescopic pole 121 extends, the positioning plate 124 is fixed to the ground by the grounding bolts, thereby fixing the telescopic frame 12 to the ground and ensuring the stability of the telescopic frame 12 during the temporary installation of cables.

[0063] like Figures 2 to 4 As shown, the extension frame 20 is rotatably mounted on the mounting frame 10. Specifically, the mounting frame 10 also includes a rotating seat 14, which is rotatably mounted on the top seat 11. The extension frame 20 is mounted on the rotating seat 14, and the angle between the lateral direction and the horizontal plane can be adjusted by rotating the rotating seat 14.

[0064] Using the temporary cable laying device provided in this embodiment, the temporary cable laying can be carried out in the following steps:

[0065] (1) When the drive unit 40 is in the first transmission state, the drive motor 41 is started. The drive motor 41 drives the take-up wheel 43 and the unwind wheel 42 to unwind the line at the same time. At the same time, the drive motor 41 drives the extension rod 21 to extend. Thus, during the process of the extension of the pull rope 34 and the suspension rope 221, the extension rod 21 extends outward to drive the first reversing part 33 and the second reversing part 222 to move, so that the suspension rope 221 is kept taut and the first reversing part 33 and the second reversing part 222 at the end move synchronously.

[0066] (2) When the extension frame 20 is extended to the required length, the take-up wheel 43 is pulled outward to separate the spline shaft 431 from the first spline groove 421. The drive handle 432 is operated to make the take-up wheel 43 rotate independently to take up the pull rope 34. The pull rope 34 pulls the slider 31 to move so that the multiple sliders 31 are extended in the lateral direction. During the extension process, the multiple sliders 31 lay the cable in a horizontal state.

[0067] Alternatively, using the temporary cable laying device provided in this embodiment, the spline shaft 431 and the first spline groove 421 are separated, and the spline shaft 431 is inserted into the second spline groove 4413, so that the driving member 40 is in the second transmission state. At this time, the driving motor 41 is started, the driving motor 41 drives the winding wheel 43 to unwind the cable, the driving motor 41 drives the extension rod 21 to extend, and the driving motor 41 drives the winding wheel 42 to wind up the cable. During the process of the suspension rope 221 extending and relaxing, the extension rod 21 extending outward drives the second reversing part 222 to move, so that the suspension rope 221 remains taut, and the first reversing part 33 and the second reversing part 222 at the end move synchronously. At the same time, the pull rope 34 is wound up, and the pull rope 34 pulls the sliding member 31 to move, so that the multiple sliding members 31 unfold in the lateral direction. During the unfolding process, the multiple sliding members 31 lay the cable in a horizontal state.
