[0050] In order to adjust the output torque of the motor according to the type of overhead wire and realize the safe and rapid installation of the overhead wire, this embodiment provides a traction device for the overhead wire, as follows: Figures 1 to 8 The specific contents of this embodiment are described in detail. It should be noted that the first direction mentioned in this embodiment refers to Figure 5 The X direction in .

[0051] like Figures 1 to 6As shown, the traction device for overhead wires includes a bearing unit 1, a power supply unit 2, a power unit 3, a safety clamp 5 and a control unit 4. Among them, the bearing unit 1 includes a base 11. The power supply unit 2 includes a battery module 21, and the battery module 21 is arranged on the base 11. The power unit 3 includes a mounting frame 31, a motor 32, a clutch assembly 33 and a pulley 34. The mounting frame 31 is arranged on the base 11, and the motor 32 and the pulley 34 are respectively arranged on two opposite side walls of the mounting frame 31. The overhead wire 6 is wound around the pulley 34, and the clutch assembly 33 is arranged on the side wall of the mounting frame 31. The clutch assembly 33 is used to couple or separate the motor 32 and the pulley 34. The safety clamp 5 is arranged on the mounting frame 31, and the safety clamp 5 is used to clamp or release the overhead wire 6. The motor 32, the clutch assembly 33 and the safety clamp 5 are all electrically connected to the control unit 4, and the control unit 4 can adjust the output torque of the motor 32, the action of the clutch assembly 33, and the opening and closing of the safety clamp 5. For example, the safety clamp 5 can be, but is not limited to, a clamping jaw cylinder.

[0052] In short, the traction device for overhead wires provided by the present invention installs the power supply unit 2, the power unit 3 and the control unit 4 on the base 11 of the bearing unit 1, wherein the motor 32, the clutch assembly 33 and the safety clamp 5 are all electrically connected to the control unit 4. When the overhead wire 6 is pulled, the required torque is first calculated according to the specifications and distance of the overhead wire 6 to be pulled, and then the set required torque value and the limited torque value are input into the control unit 4, and the control unit 4 adjusts the torque of the motor 32 to adapt to the operation requirements of different overhead wires 6. When the traction force exceeds the limited torque value, the control unit 4 generates a signal to activate the clutch assembly 33, so that the motor 32 is separated from the wire pulley 34, thereby avoiding the danger of the electric pole tipping due to excessive traction. In order to avoid the sudden loss of power of the wire pulley 34 after the clutch assembly 33 is disengaged, causing the released overhead wire 6 to fall and cause other accidents, a safety clamp 5 is arranged on the side of the wire appearance direction on the mounting frame 31, and the safety clamp 5 is linked with the clutch assembly 33 through the control unit 4. When the clutch assembly 33 is actuated to separate the wire pulley 34 from the motor 32 serving as a power source, the safety clamp 5 is actuated to clamp the wire to prevent the wire from falling.

[0053] Further, a driving shaft 321 is coaxially arranged at one end of the motor 32, a driven shaft 37 is coaxially arranged at one end of the pulley 34, and the clutch assembly 33 includes a driving flange 331, a driven flange 332 and a latch member 333. The driving flange 331 has a plurality of first latch holes 3311, which are arranged circumferentially at intervals around the axis of the driving flange 331, and the driving flange 331 is fixedly sleeved on the driving shaft 321. The driven flange 332 has a plurality of second latch holes 3321, which are arranged circumferentially at intervals around the axis of the driven flange 332, and the driven flange 332 is fixedly sleeved on the driven shaft 37. The latch member 333 is inserted into the first latch hole 3311, and one end of the latch member 333 can move along the first direction and be inserted into the second latch hole 3321. The latch member 333 is inserted into the first latch hole 3311 and rotates with the driving flange 331 under the drive of the motor 32. When the motor 32 and the pulley 34 need to be coupled, one end of the latch member 333 moves along the first direction and is inserted into the second latch hole 3321. At this time, the latch member 333 is inserted into the first latch hole 3311 and the second latch hole 3321 at the same time, realizing the power coupling of the driving shaft 321 and the driven shaft 37, thereby facilitating the laying of the overhead wire 6.

[0054] Furthermore, the clutch assembly 33 further includes a first annular portion 334, a second annular portion 335 and a pusher 336. The second annular portion 335 is rotatably disposed in the first annular portion 334, and a plurality of latch members 333 are circumferentially spaced and disposed on the second annular portion 335. The fixed end of the pusher 336 is connected to the mounting frame 31, and the telescopic end of the pusher 336 is connected to the first annular portion 334. The pusher 336 is used to push the first annular portion 334 to move along the first direction, and the pusher 336 is electrically connected to the control unit 4. Exemplarily, the pusher 336 may be, but is not limited to, a linear telescopic cylinder or an electric push rod.

[0055] Furthermore, the clutch assembly 33 further includes a bearing 337; the second annular portion 335 is embedded in the inner ring of the bearing 337, and the outer ring of the bearing 337 is embedded in the first annular portion 334. By arranging the bearing 337 between the first annular portion 334 and the second annular portion 335, the second annular portion 335 can rotate in the first annular portion 334.

[0056] Optionally, the power unit 3 further includes a torque sensor 35, which is disposed on the driven shaft 37 and is electrically connected to the control unit 4. By adding the torque sensor 35, the torque applied to the driven shaft 37 can be monitored in real time.

[0057] The specific action process is as follows: when the traction device for overhead wires works under normal torque conditions, the pusher 336 is in an extended state, pushing the first annular portion 334 and the second annular portion 335 to move in the first direction (i.e., the axial direction) toward the pulley 34; at this time, the latch 333 on the second annular portion 335 passes through the first latch hole 3311 on the driving flange 331 and penetrates into the second latch hole 3321 on the driven flange 332, so that the power of the motor 32 is transmitted to the driven shaft 37. When the torque sensor 35 detects that the limited torque is exceeded, the pusher 336 quickly retracts, driving the first annular portion 334 and the second annular portion 335 to move in the first direction toward the motor 32; at this time, the latch 333 of the second annular portion 335 disengages from the second latch hole 3321 on the driven flange 332, and the driving flange 331 and the driven flange 332 are disengaged, so that the pulley 34 loses power, thereby avoiding pulling down the pole.

[0058] Alternatively, if Figure 4 Combination Figure 7 As shown, the clutch assembly 33 further includes a transmitter 338 and a receiver 339, one of which is disposed on the driving flange 331, and the other of which is disposed on the driven flange 332. In order to facilitate the re-coupling of the clutch assembly 33 after disengagement, a transmitter 338 is disposed at the position of any first latch hole 3311 on the outer edge of the driving flange 331, and a corresponding receiver 339 is disposed at the position of any second latch hole 3321 on the outer edge of the driven flange 332. When the clutch assembly 33 needs to be re-coupled, the motor 32 drives the driving flange 331 to rotate slowly, and when the signal emitted by the transmitter 338 is received by the receiver 339, the motor 32 stops rotating; at this time, the pusher 336 extends to push the latch member 333 on the second annular portion 335 to re-couple the driving flange 331 and the driven flange 332.

[0059] Alternatively, if Figure 3 Combination Figure 8 As shown, the power unit 3 further includes a cover plate 36, which is arranged on the mounting frame 31, and a detection window 361 is arranged on the cover plate 36. After the fault of the traction device for the overhead wire exceeding the limited torque is eliminated, it is necessary to couple the automatic clutch assembly 33 again. For the convenience of operation, a detection window 361 covered with glass or other transparent materials is provided on the top of the mounting frame 31, and the positions of the driving flange 331 and the driven flange 332 are observed through the detection window 361, so as to facilitate the coupling connection.

By adding a plurality of wheels 14 at the bottom of the machine base 11, it is convenient to move the overall traction device. After the traction device moves to the target position, the telescopic leg 12 is extended so that the anchoring foot 13 contacts the ground, and the anchoring foot 13 can be fixed to the ground by passing a bolt through the arc-shaped notch 131.

[0061] Furthermore, if Figure 2 As shown, the base 11 is provided with a battery compartment 111, the bottom wall of the battery compartment 111 is provided with a plug 1111, the bottom of the battery module 21 is provided with a slot 211, and the plug 1111 is plugged into the slot 211. The relative cooperation between the plug 1111 and the slot 211 enables the battery module 21 to be quickly assembled and disassembled from the battery compartment 111.

[0062] Furthermore, the power supply unit 2 also includes a solar panel 22, which is disposed on the battery module 21 and electrically connected to the battery module 21. The solar panel 22 is disposed on the top of the battery module 21, and can charge the battery module 21 during outdoor operation, thereby extending the working time of the traction device for the overhead wire.
