[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9As shown, an embodiment of the present invention provides a temporary cable installation device, which includes a mounting frame 10, an extension frame 20, a wire supporting member 30 and a driving member 40. The extension frame 20 is telescopically arranged on the mounting frame 10 in a transverse direction. The wire supporting member 30 includes a plurality of sliding members 31 arranged on the extension frame 20 in a transverse direction. The sliding members 31 are movably arranged relative to the extension frame 20 in the transverse direction. The wire supporting member 30 has a storage state and an expansion state. When the wire supporting member 30 is in the storage state, the plurality of sliding members 31 are close to each other. When the wire supporting member 30 is in the expansion state, the plurality of sliding members 31 are away from each other to expand in the transverse direction. The driving member 40 is arranged on the mounting frame 10. The driving member 40 is respectively connected to the extension frame 20 and the wire supporting member 30. The driving member 40 can drive the extension frame 20 to retract and retract. The driving member 40 can also drive the wire supporting member 30 to switch between the storage state and the expansion state.

[0035] The temporary cable installation device provided in this embodiment includes a mounting frame 10, an extension frame 20, a wire supporting member 30 and a driving member 40. When temporarily installing a cable 50, the cable 50 is first hung on the wire supporting member 30 in a stored state, and the extension frame 20 is driven to expand in a transverse direction by the driving member 40. Then, the driving member 40 is used to drive the wire supporting member 30 to switch to an expanded state, so that a plurality of sliding members 31 are expanded in a transverse direction, and the cable 50 is installed in a transverse direction by the plurality of sliding members 31, so as to prevent the cable 50 installed in the transverse direction by the wire supporting member 30 from falling due to its own weight, thereby improving the stability and safety of the temporary installation of the cable.

[0036] like Figures 1 to 4 , Figure 7 as well as Fig. 9As shown, the wire supporting member 30 also includes a connecting rope 32, a first reversing portion 33 and a pulling rope 34. The connecting rope 32 extends in the transverse direction and is respectively connected to the plurality of sliding members 31. One end of the connecting rope 32 is fixedly connected to the starting end of the stretching frame 20. When the wire supporting member 30 is in the storage state, the portion of the connecting rope 32 located between two adjacent sliding members 31 is folded. When the wire supporting member 30 is in the unfolded state, the plurality of sliding members 31 are away from each other, and the portion of the connecting rope 32 located between two adjacent sliding members 31 is unfolded. The first reversing portion 33 is arranged at the rear end of the stretching frame 20. The pulling rope 34 is wound around the first reversing portion 33. The first end of the pulling rope 34 is connected to a sliding member 31 arranged near the rear end among the plurality of sliding members 31. The driving member 40 can be driven and connected to the second end of the pulling rope 34. When temporarily installing the cable 50, first hang the cable 50 on the wire supporting member 30 in the storage state, and use the driving member 40 to drive the extension frame 20 to expand in the transverse direction, so that the tail end and the starting end of the extension frame 20 are separated from each other, and then use the driving member 40 to reel in the pull rope 34, so that the pull rope 34 pulls the sliding member 31 to expand the part of the connecting rope 32 located between two adjacent sliding members 31, so that the multiple sliding members 31 are expanded in the transverse direction, and the cable 50 is installed in the transverse direction using the multiple sliding members 31.

[0037] The first reversing portion 33 is used to reverse the transmission direction of the pull rope 34, so that the force of the driving member 40 on the second end of the pull rope 34 can be set at an angle with the force of the first end of the pull rope 34 on the sliding member 31, which facilitates the flexible layout of the driving member 40. In addition, 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 is used to pull the multiple sliding members 31 to unfold in the transverse direction, the connecting rope 32 and the multiple sliding members 31 form an unfolding effect with one end fixed.

[0038] like Fig. 9 As shown, in this embodiment, one sliding member 31 disposed near the starting end among the plurality of sliding members 31 is connected to the first reversing portion 33 disposed at the starting end.

[0039] like Figures 1 to 4 as well as Figure 7As shown, the stretching frame 20 includes a suspension assembly 22 and two stretching rods 21, the two stretching rods 21 are symmetrically arranged on the mounting frame 10 relative to the mounting frame 10, the extension direction of the stretching rod 21 is parallel to the transverse direction, the starting end is corresponding to the end of one stretching rod 21 away from the mounting frame 10, and the tail end is corresponding to the end of the other stretching rod 21 away from the mounting frame 10, the suspension assembly 22 includes a suspension rope 221 and two second switching parts 222, the two second switching parts 222 are respectively arranged at the starting end and the tail end, the suspension rope 221 is sleeved on the two second switching parts 222, the driving member 40 is respectively connected to the stretching rod 21 and the suspension rope 221 to drive the stretching rod 21 and the suspension rope 221 to extend or shorten at the same time, and a plurality of sliding members 31 are slidably sleeved on the suspension rope 221 along the extension direction of the suspension rope 221, and the plurality of sliding members 31 are located between the two second switching parts 222. In the process of using the driving member 40 to drive the extension frame 20 to expand in the lateral direction, the driving member 40 drives the extension rod 21 and the suspension rope 221 to extend simultaneously. Since the starting end is arranged corresponding to the end of one telescopic rod away from the mounting frame 10, and the tail end is arranged corresponding to the end of the other telescopic rod away from the mounting frame 10, the tail end and the starting end are separated from each other, so that the two second switching parts 222 are separated from each other, and the first switching part 33 moves in the direction away from the starting end, thereby tightening the suspension rope 221, and then the driving member 40 is used to reel in the pull rope 34, so that the pull rope 34 pulls the sliding member 31, so that the multiple sliding members 31 are expanded along the extension direction of the suspension rope 221, and the multiple sliding members 31 are used to set up the cable 50 in the lateral direction.

[0040] Among them, the second reversing part 222 is used to reverse 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 direction-changing portion 33 and the second direction-changing portion 222 use fixed pulleys.

[0042] like Figures 1 to 7As shown, the driving member 40 includes a driving motor 41, a winding wheel 42 and a reel 43, the driving motor 41 is arranged on the mounting frame 10, the winding wheel 42 is rotatably arranged on the mounting frame 10, the suspension rope 221 is wound around the winding wheel 42 and connected to the winding wheel 42, the driving motor 41 is drivingly connected to the winding wheel 42 and the stretching rod 21 respectively, the reel 43 is rotatably arranged on the mounting frame 10, the second end of the pull rope 34 is wound around the reel 43 and connected to the reel 43, the driving motor 41 can be drivingly connected to the reel 43, wherein the driving member 40 has a first transmission state and a second transmission state, when the driving member 40 is in the first transmission state, the reel 43 and the unwinding wheel 42 reel in or unwind at the same time, when the driving member 40 is in the second transmission state, the reel 43 can reel in or unwind independently relative to the unwinding wheel 42. When the driving member 40 is in the first transmission state, the driving motor 41 is started, and the driving motor 41 drives the winding wheel 43 and the unwinding wheel 42 to release the line at the same time. At the same time, the driving motor 41 drives the stretching rod 21 to extend. Therefore, in the process of stretching and relaxing the pull rope 34 and the suspension rope 221, the first reversing part 33 and the second reversing part 222 are driven to move by the outwardly extending stretching rod 21 to keep the suspension rope 221 in a taut state.

[0043] It should be noted that when the driving member 40 is in the second transmission state, the winding wheel 43 can independently wind up or unwind the line relative to the unwinding wheel 42, including:

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

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

[0046] Thus, the driving member 40 is switched to the second transmission state, and the pull rope 34 is rolled up by the winding wheel 43. The pull rope 34 pulls the sliding member 31 to move, so that the multiple sliding members 31 are unfolded in the transverse direction. During the unfolding process, the multiple sliding members 31 set the cable to a horizontal state.

[0047] like Figure 5 and Figure 6As shown, the winding wheel 43 has a spline shaft 431 and a driving handle 432, and the driving member 40 has a first spline groove 421. When the driving member 40 is in the first transmission state, the spline shaft 431 is inserted into the first spline groove 421, and when the driving member 40 is in the second transmission state, the spline shaft 431 is separated from the first spline groove 421. When the extension frame 20 is unfolded to the required length, the winding wheel 43 is pulled outward to separate the spline shaft 431 from the first spline groove 421, and the driving handle 432 is operated to make the winding wheel 43 rotate alone to reel in the drawstring 34.

[0048] like Figure 5 and Figure 6 As shown, the driving member 40 also includes a transmission assembly 44 arranged between the driving motor 41 and the stretching rod 21, and 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 wheel 42. A second spline groove 4413 is arranged on the transmission wheel 441. When the driving member 40 is in the second transmission state, the spline shaft 431 is inserted into the second spline groove 4413. When the spline shaft 431 is inserted into the second spline groove 4413, the drive motor 41 is started, the drive motor 41 drives the winding wheel 43 to pay out the line, the drive motor 41 drives the stretching rod 21 to extend, and the drive motor 41 drives the winding wheel 42 to reel in the line. In the process of stretching and relaxing the suspension rope 221, the second reversing part 222 is driven to move by the outwardly extending stretching rod 21 to keep the suspension rope 221 taut, and the first reversing part 33 and the second reversing part 222 arranged at the rear end move synchronously, and the pull rope 34 is reeled in, and the pull rope 34 pulls the sliding member 31 to move, so that the multiple sliding members 31 are unfolded in the transverse direction. During the unfolding process, the multiple sliding members 31 set the cable to 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 arranged on the mounting frame 10, the driving motor 41 is drivingly connected to the driving pulley 4411, the rotation direction of the driving pulley 4411 is opposite to the rotation direction of the winding wheel 42, the second spline groove 4413 is arranged on the driving pulley 4411, the driven pulley 4412 is rotatably arranged on the mounting frame 10, the driven pulley 4412 is drivingly connected to the stretching rod 21, and the transmission assembly 44 also includes a transmission belt 442, and the transmission belt 442 is sleeved on the driving pulley 4411 and the driven pulley 4412. The above-mentioned belt drive is adopted to facilitate long-distance transmission, so that the driven pulley 4412 is set at a higher position along with the stretching frame 20, and the drive motor 41, the active pulley 4411, the winding wheel 43 and other structures are set at a lower position. While increasing the height of the line, it is convenient for personnel to inspect and operate the drive motor 41, the active pulley 4411, the winding wheel 43 and other structures from the ground.

[0050] like Figure 5 and Figure 6 As shown, the driving member 40 also includes a first gear 45, a second gear 46, a third gear 47 and a fourth gear 48. The driving motor 41 is drivingly connected to the first gear 45. The first spline groove 421 is arranged on the first gear 45. The second gear 46 is coaxially arranged with the driving pulley 4411 and connected with the driving pulley 4411. The first gear 45 and the second gear 46 are meshed. The third gear 47 is coaxially arranged with the driving pulley 4411 and connected with the driving pulley 4411. The fourth gear 48 is coaxially arranged with the winding wheel 42 and connected with the winding wheel 42. The third gear 47 is meshed with the fourth gear 48. The first gear 45, the second gear 46, the third gear 47 and the fourth gear 48 are used for transmission, so that the rotation directions of the first spline groove 421 and the second spline groove 4413 are opposite, and the transmission of the driving member 40 is reliable.

[0051] like Figure 2 and Figure 3As shown, the stretching rod 21 includes a fixed rod 211, a movable rod 212, a first transmission shaft 213 and a second transmission shaft 214. The fixed rod 211, the movable rod 212 and the first transmission shaft 213 all extend in the transverse direction. The fixed rod 211 is fixedly set on the mounting frame 10, the movable rod 212 is movably set on the fixed rod 211 in the transverse direction, the first transmission shaft 213 is rotatably set on the fixed rod 211 around its axis, and the extension direction of the second transmission shaft 214 is perpendicular to the transverse direction. The driven pulley 4412 is drivingly connected to the second transmission shaft 214, the second transmission shaft 214 is drivingly connected to the first transmission shaft 213 to drive the first transmission shaft 213 to rotate, and the first transmission shaft 213 is drivingly connected to the movable rod 212 to drive the movable rod 212 to move. With the stretch rod 21 described above, 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 worm 216 is coaxially arranged with the second transmission shaft 214. The worm 216 and the worm wheel 215 are meshed, 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, Figure 7 and Figure 8 As shown, the first transmission shafts 213 of the two stretching rods 21 are symmetrically arranged relative to the mounting frame 10 , and one end of the first transmission shafts 213 of the two stretching rods 21 facing the mounting frame 10 is connected to the same worm gear 215 .

[0054] like Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, the stretching rod 21 also includes a transmission block 217.
