[0002] Converting a straight pole with load into a strain pole is a complex live working operation. It is necessary to convert the straight pole into a strain pole while ensuring continuous power supply to users, so as to enhance the mechanical strength of the line and the fault isolation ability.

[0003] When converting a straight pole into a strain pole, the crossarm is installed on the pole, and the insulator is installed on the crossarm to support the conductor.

[0048] Example 1

[0049] When converting a straight pole to a strain pole, it is necessary to perform operations of lifting and fixing the live conductor. The existing method is that the operator lifts the conductor manually and uses an insulating rope to lift the conductor. However, generally, the weight of the conductor far exceeds the range of human power, posing a safety hazard and may also cause the work to be unable to be carried out.

[0050] Based on this, as Figure 1 and Figure 2 shown, this embodiment discloses a conductor lifting tool for converting a live straight pole to a strain pole, including:

[0051] A support assembly 1, including a fixing part 12 and a support rod 11. The fixing part 12 is installed on the cross arm 6 and is arranged in a triangle. There are multiple support rods 11, and the corresponding support rods 11 are connected to the fixing part 12. The multiple support rods 11 form a tripod through a connecting block;

[0052] A lifting mechanism 2, slidably arranged between two support rods 11, for lifting and supporting the conductor;

[0053] A wire tightening assembly 3, installed on the connecting block and connected to the lifting mechanism 2, for driving the lifting mechanism 2 to rise or fall.

[0054] In this embodiment, the fixing part 12 in the support assembly 1 is fixedly installed on the cross arm 6. The fixing part 12 provides a stable support point for the whole tool, ensuring the stability and reliability of the tool. The cross arm 6 is two parallel horizontal bars. The fixing part 12 includes a first fixing foot 121 and a second fixing foot 122. There are two second fixing feet 122, and the two second fixing feet 122 are symmetrically arranged and are both located on the side close to the conductor. The first fixing foot 121 and the two second fixing feet 122 are connected to the corresponding support rods 11.

[0055] The fixing method of the first fixing foot 121 and the second fixing foot 122 to the cross arm 6 is as follows: The lower parts of the first fixing foot 121 and the two second fixing feet 122 are each provided with a U-shaped notch matching the horizontal bar. The first fixing foot 121 and the two second fixing feet 122 are respectively inserted into the corresponding horizontal bar through the U-shaped notch. The first fixing foot 121 is fixedly connected to one of the horizontal bars by bolts; the two second fixing feet 122 are respectively located on the two horizontal bars, and a fixing member 5 is connected between the two second fixing feet 122. The two second fixing feet 122 can move towards each other or away from each other through the fixing member 5. When the two second fixing feet 122 move towards each other, they can be clamped and fixed on the horizontal bar.

[0056] Through the stable support of the first fixing foot 121 and the second fixing foot 122, it provides a guarantee for the subsequent lifting and tightening work.

[0057] Specifically, the fixing member 5 is a bidirectional lead screw 51 and a driving block 52. There are two driving blocks 52, and the two driving blocks 52 are respectively connected to the two second fixing feet 122. The bidirectional lead screw 51 is horizontally rotatably arranged between the driving blocks 52 and is threadedly connected to the driving blocks 52 to drive the two driving blocks 52 to move towards or away from each other. One end of the bidirectional lead screw 51 is connected to a second crank 53.

[0058] The specific working process is as follows: The second crank 53 drives the bidirectional lead screw 51 to rotate. The thread directions on both sides of the bidirectional lead screw 51 are opposite. Since before the fixing member 5 is used, the U-shaped structure of the second fixing foot 122 is cooperated with the cross bar to a certain extent, thus restricting the rotation of the driving block 52 connected to the second fixing foot 122. Therefore, when the bidirectional lead screw 51 rotates, it will drive the two driving blocks 52 to move towards each other, and then the two second fixing feet 122 approach the cross bar to achieve clamping and fixing. In addition, in this embodiment, threads with a relatively high coefficient of friction are selected to ensure that the threads on the bidirectional lead screw 51 have a strong self-locking ability, that is, the two driving blocks 52 will not easily move autonomously, ensuring the stability of the connection between the second fixing foot 122 and the corresponding cross bar.

[0059] When the wire lifting work is completed and the whole tool needs to be removed, the second crank 53 drives the bidirectional lead screw 51 to rotate in the reverse direction. Since the thread directions on both sides of the bidirectional lead screw 51 are opposite, at this time, the bidirectional lead screw 51 will drive the two driving blocks 52 to move away from each other, and then the two second fixing feet 122 move away from the corresponding cross bar for loosening.

[0060] After ensuring the firm connection of the first fixing foot 121 and the two second fixing feet 122, the multiple support rods 11 of the support framework of the support assembly 1 are used to bear the weights of the lifting mechanism 2 and the wire tightening assembly 3. The multiple support rods 11 form a tripod structure, ensuring the stable setting of the lifting mechanism 2 and the wire tightening assembly 3.

[0061] Specifically, as Figure 1 and Figure 2 shown, the lifting mechanism 2 includes a wire hook 21, a sliding block 22 and a sliding hole 23. The sliding hole 23 is opened on two support rods 11 corresponding to the two second fixing feet 122 respectively. The sliding block 22 is slidably arranged between the two sliding holes 23. The wire hook 21 is installed on the sliding block 22.

[0062] Among them, there are two wire hooks 21, and the two wire hooks 21 are symmetrically arranged on the sliding block 22. The sliding hole 23 is a strip-shaped sliding hole, and the sliding hole 23 is arranged along the axis of the support rod 11. The two ends of the sliding block 22 are respectively located in the two strip-shaped sliding holes and slide directionally along the length direction of the strip-shaped sliding hole, ensuring that the wire hook 21 has a lifting space.

[0063] It can be known that during the hoisting of the insulator string of the straight-line tower by manpower, the insulator string may shift due to uneven stress, resulting in a change in the angle between the insulator string and the conductor, and further generating a lateral tension. However, in this embodiment, through the cooperation of the lifting mechanism 2 and the wire tightening assembly 3, that is, the wire hook 21 lifts the wire and then the wire is hoisted by the wire tightening assembly 3. The pulling forces of the two wire hooks 21 on the wire are the same, avoiding the situation of uneven stress and generating lateral tension when the insulator string is lifted. In addition, the tripod formed by the three support rods 11 has stability and can well support the weight of the wire.

[0064] Embodiment 2

[0065] Based on Embodiment 1, as Figure 1 shown, in this embodiment, an instrument transformer 7 is arranged between the two wire hooks 21. Specifically, during the transformation of the strain pole, it is necessary to monitor the line current in real time to ensure that the current of the line after transformation is within the safe range. The instrument transformer provides a standardized current signal for the measuring device, facilitating accurate measurement and recording.

[0066] As Figure 1 and Figure 2 shown, the two support rods 11 correspondingly connected to the second fixed foot 122 both include a first support rod 111 and a second support rod 112. The first support rod 111 and the second support rod 112 are arranged in parallel and fixedly connected through a connecting cross block 113. The sliding block 22 is slidably arranged on the two second support rods 112. A sliding rod 8 is slidably arranged between the two first support rods 111. The other two first support rods 111 are provided with limiting holes 9 for the sliding rod 8 to slide. The limiting holes 9 are arranged along the axial direction of the first support rod 111.

[0067] The sliding rod 8 is connected to the instrument transformer 7 and supports the instrument transformer 7. In addition, the sliding rod 8 is connected to the sliding block 22 to realize the synchronous rising or falling of the wire hook 21 and the instrument transformer 7. Therefore, when the wire hook 21 lifts the wire, the wire will also pass through the instrument transformer 7. At this time, the instrument transformer 7 converts the high current into a low current, facilitating measurement with a standard ammeter. The instrument transformer 7 will rise or fall synchronously with the wire hook 21.

[0068] Embodiment 3

[0069] Based on Embodiment 1, as Figure 2 and Figure 4As shown, the threads of the bidirectional lead screw 51 will gradually wear, resulting in a weakened self-locking ability. To further improve the performance of the fixing member 5, another form of the fixing member is provided in this embodiment: the fixing member 5 is a ratchet wrench 54, a threaded barrel 55, and a threaded rod 56. There are two threaded rods 56, and the two threaded rods 56 are respectively connected to the two second fixing feet 122 correspondingly; the threaded barrel 55 is located between the two threaded rods 56 and is threadedly connected to the two threaded rods 56 respectively; the ratchet wrench 54 is installed on the threaded barrel 55 and is used to drive the threaded barrel 55 to rotate.

[0070] The ratchet wrench 54 internally includes a ratchet 541 that can rotate unidirectionally and a pawl 542. The unidirectional drive is achieved through the engagement of the pawl 542 with the tooth ring of the ratchet 541. The specific working process of the fixing member 5 is as follows: the ratchet wrench 54 drives the threaded barrel 55 to rotate unidirectionally. The internal threads at both ends of the threaded barrel 55 have opposite helix directions and are respectively threadedly connected to the two threaded rods 56 correspondingly. When the threaded barrel 55 rotates, since the second fixing feet 122 have a certain fit on the crossbar before the fixing member 5 is started, the rotation of the two threaded rods 56 is restricted. At this time, the two threaded rods 56 move towards each other and drive the two second fixing feet 122 to clamp the corresponding crossbar. Due to the structure of the ratchet handle itself, the threaded barrel 55 is locked to a certain extent after rotation, ultimately ensuring the stable connection between the two second fixing feet 122 and the crossbar.

[0071] It should be noted that the ratchet wrench 54 in this embodiment can achieve direction change. As Figure 6 shown, specifically, two types of pawls 542 can be provided inside the variable-direction ratchet wrench 54. The two pawls 542 are located on the left and right sides inside the ratchet handle 54 and have different setting directions. Both pawls 542 are cooperatively connected to the ratchet 541 through springs 544; a switch 543 is provided between the two pawls 542. The switch 543 is in the shape of a cam. When the switch 543 rotates to one side and abuts against the left pawl 542, this pawl 542 is separated from the ratchet 541, and the other pawl 542 cooperates with the ratchet 541 under the action of the spring 544 to achieve unidirectional rotation; when the switch 543 rotates to the other side and abuts against the right pawl 542, at this time, the left pawl 542 cooperates with the ratchet 541 to complete the direction change. It should be noted that the abutting force of the converter 543 on the pawl 542 is greater than the elastic force of the spring 544, and the converter 543 will not rotate autonomously under normal conditions and can only complete the rotation under manual drive.

[0072] After the direction of the pawl 542 is changed, at this time, the ratchet wrench 54 drives the threaded barrel 55 to rotate reversely and unidirectionally. The threaded barrel 55 drives the two threaded rods 56 to move away from each other, thereby driving the two second fixing feet 122 away from the crossbar to achieve loosening.

[0073] Embodiment 4

[0074] In addition, as Figure 5 shown, based on Embodiment 1, this embodiment is configured as follows: The wire tightening assembly 3 includes a load-bearing belt 32, a wire tightening wheel 34, a handle 33, a winding drum 35, and a ratchet and pawl mechanism; the wire tightening wheel 34 is located at the connecting block, the winding drum 35 and the ratchet and pawl mechanism are arranged on the support rod 11 connected to the first fixed foot 121. One end of the load-bearing belt 32 is connected to the sliding block 22, and one end bypasses the wire tightening wheel 34 and is connected to the winding drum 35. The handle 33 is installed outside the winding drum 35, and the ratchet and pawl mechanism (not shown in the figure) is installed on the winding drum 35 for restricting the one-way rotation of the winding drum 35. It can be known that the ratchet and pawl mechanism is a conventional structure and will not be elaborated here too much.

[0075] The specific process is as follows: Rotate the handle 33, and the winding drum 35 starts to work. At this time, the load-bearing belt 32 starts to drive the wire hook 21 and the wire to rise. Among them, the ratchet and pawl prevent the reverse rotation of the drum, and the tightening wheel changes the direction of the force, reduces friction, and improves the transmission efficiency; finally, the wire hook 21 steadily lifts the wire.

[0076] Embodiment 5

[0077] Based on Embodiment 1, as Figure 1 shown, the wire tightening assembly 3 is also provided with another form: The wire tightening assembly 3 includes a wire tightener 31. The wire tightener 31 is connected to the sliding block 22 through the load-bearing belt 32. The process of lifting the wire is as follows: Two wire hooks 21 hook the wire, and the wire tightener 31 tightens the sliding block 22 through the load-bearing belt 32. The wire tightener 31 generates a continuous pulling force through its mechanical structure and gradually tightens the load-bearing belt 32 to a predetermined tension. This process avoids the inefficiency and instability of manual wire pulling and ensures that the wire remains taut during the lifting process. It can be known that the load-bearing belt 32 has properties such as high strength and wear resistance and can stably bear the weight of the wire. The wire tightener in this embodiment is a conventional design, so it will not be elaborated here.

[0078] Embodiment 6

[0079] The wire hook 21 is used to cooperate with the wire. Since the wire hook 21 has a certain curvature, when lifting the wire, the wire needs to be aligned with the internal space of the hook for cooperation. Therefore, it is often necessary to adjust the angle of the wire hook 21 to align the space of the wire hook 21 with the wire.

[0080] Based on Embodiment 1, as Figure 2 and Figure 4As shown in the figure, it is set that the first fixed foot 121 and the two second fixed feet 122 are rotatably connected to the corresponding support rod 11; an angle adjustment component 4 is arranged between the first fixed foot 121 and the corresponding support rod 11 for adjusting the angle of the wire hook 21. It should be noted that the support rod 11 connected to the first fixed foot 121 can rotate in all directions and has strong mobility. Specifically, the angle adjustment component 4 includes a driving frame 41, a first lead screw 42, a limiting rod 44 and a moving block 45. The driving frame 41 is installed on the top of the first fixed foot 121; the first lead screw 42 is horizontally arranged and rotated in the driving frame 41, and one end of the first lead screw 42 is connected with a first crank 43; the limiting rod 44 is arranged in parallel with the first lead screw 42; the moving block 45 is threadedly connected with the first lead screw 42 and slidably connected with the limiting rod 44, and the bottom of the moving block 45 is rotatably connected with the corresponding support rod 11.

[0081] Among them, the driving frame 41 provides support for the first lead screw 42 and the limiting rod 44. In this embodiment, two limiting rods 44 are provided, and the two limiting rods 44 are respectively arranged on both sides of the first lead screw 42. Threaded holes are formed in the moving block 45 for threaded connection with the first lead screw 42; in addition, sliding holes are also formed in the moving block 45 for the two limiting rods 44 to pass through.

[0082] The specific working process of the angle adjustment component 4 is as follows: the first crank 43 drives the first lead screw 42 to rotate, and the moving block 45 starts to move horizontally to the left under the limitation of the limiting rod 44 and the threaded connection with the first lead screw 42. At this time, the support rod 11 corresponding to the moving block 45 moves horizontally to the left. Due to the fixation of the second fixed foot 122, the two support rods 11 respectively connected to the two second fixed feet 122 rotate. At this time, the wire hooks 21 located on the two support rods 11 rotate counterclockwise accordingly.

[0083] On the contrary, when the first crank 43 drives the first lead screw 42 to rotate in the reverse direction, the moving block 45 starts to move horizontally to the right under the limitation of the limiting rod 44 and the threaded connection with the first lead screw 42. At this time, the support rod 11 corresponding to the moving block 45 moves horizontally to the right. Due to the fixation of the second fixed foot 122, the two support rods 11 respectively connected to the two second fixed feet 122 rotate. At this time, the wire hooks 21 located on the two support rods 11 rotate clockwise accordingly.

[0084] Finally, through the angle adjustment of the wire hook 21, the wire can finally accurately extend into the internal space of the wire hook 21, ensuring the accuracy of the connection between the wire hook 21 and the wire. In addition, by adjusting the angle of the wire hook 21 after lifting the wire, the wire can be firmly buckled in the space of the wire hook 21, avoiding potential safety hazards caused by the wire slipping.

[0085] The specific embodiments described above further elaborate on the objective, technical solution and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
