[0048] Example 1

[0049] When converting a straight pole into a tension pole, it is necessary to lift and secure the live conductor. The current method is for workers to lift the conductor manually using insulated ropes. However, the weight of the conductor usually far exceeds the range of human strength, posing a safety hazard and potentially making it impossible to carry out the work.

[0050] Based on this, such as Figure 1 and Figure 2 As shown, this embodiment discloses a lifting tool for a load-bearing straight pole converted into a tension pole conductor, comprising:

[0051] Support assembly 1 includes a fixing part 12 and a support rod 11. The fixing part 12 is mounted on the crossbeam 6 and is arranged in a triangular shape. Multiple support rods 11 are provided and connected to the corresponding fixing parts 12. Multiple support rods 11 form a triangular frame through connecting blocks.

[0052] The lifting mechanism 2 is slidably arranged between the two support rods 11 and is used to lift and support the wire.

[0053] The tensioning assembly 3 is installed on the connecting block and connected to the lifting mechanism 2, and is used to drive 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 crossarm 6. The fixing part 12 provides a stable support point for the entire tool, ensuring the stability and reliability of the tool. The crossarm 6 consists of two parallel crossbars. The fixing part 12 includes a first fixing foot 121 and a second fixing foot 122. Two second fixing feet 122 are provided, symmetrically arranged and located on the side closest to the conductor. The first fixing foot 121 and the two second fixing feet 122 are connected to the corresponding support rod 11.

[0055] The first fixed foot 121 and the second fixed foot 122 are fixed to the crossarm 6 as follows: the lower part of the first fixed foot 121 and the two second fixed feet 122 are provided with U-shaped notches that match the crossarm. The first fixed foot 121 and the two second fixed feet 122 are respectively inserted into the corresponding crossarm through the U-shaped notches. The first fixed foot 121 is fixedly connected to one of the crossarms by bolts. The two second fixed feet 122 are respectively located on the two crossarms and are connected by a fixing member 5. The two second fixed feet 122 can move towards each other or away from each other through the fixing member 5. When the two second fixed feet 122 move towards each other, they can be clamped and fixed to the crossarm.

[0056] The stable support provided by the first fixed foot 121 and the second fixed foot 122 ensures the smooth operation of subsequent lifting and tightening work.

[0057] Specifically, the fixing component 5 consists of a bidirectional lead screw 51 and a drive block 52. There are two drive blocks 52, and the two drive blocks 52 are respectively connected to two second fixing feet 122. The bidirectional lead screw 51 is arranged laterally between the drive blocks 52 and is threadedly connected to the drive blocks 52 to drive the two drive 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 threads on both sides of the bidirectional lead screw 51 rotate in opposite directions. Before the use of the fixing member 5, the U-shaped structure of the second fixing foot 122 engages with the crossbar to a certain extent, thereby restricting the rotation of the drive block 52 connected to the second fixing foot 122. Therefore, the rotation of the bidirectional lead screw 51 will drive the two drive blocks 52 to move towards each other, and then the two second fixing feet 122 will approach the crossbar to achieve clamping and fixing. In addition, this embodiment selects threads with a high coefficient of friction to ensure that the threads on the bidirectional lead screw 51 have a strong self-locking ability, that is, the two drive blocks 52 will not easily move on their own, ensuring the stability of the connection between the second fixing foot 122 and the corresponding crossbar.

[0059] When the entire tool needs to be removed after the wire lifting work is completed, the second crank 53 drives the bidirectional lead screw 51 to rotate in the opposite direction. Since the threads on both sides of the bidirectional lead screw 51 rotate in opposite directions, the bidirectional lead screw 51 will drive the two drive blocks 52 to move in opposite directions, thereby releasing the two second fixed feet 122 away from the corresponding crossbars.

[0060] After ensuring a stable connection between the first fixed foot 121 and the two second fixed feet 122, multiple support rods 11, which serve as the support frame of the support assembly 1, are used to bear the weight of the lifting mechanism 2 and the tensioning assembly 3. The multiple support rods 11 form a triangular frame structure, ensuring the stable setting of the lifting mechanism 2 and the tensioning assembly 3.

[0061] Specifically, such as Figure 1 and Figure 2 As 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 that correspond to the two second fixed 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] Two wire hooks 21 are provided, and the two wire hooks 21 are symmetrically arranged on the sliding block 22; the sliding hole 23 is a strip-shaped sliding hole, which is set 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 in a direction along the length of the strip-shaped sliding hole to ensure that the wire hook 21 has a lifting space.

[0063] It is known that during the manual lifting of insulator strings on a straight-line tower, uneven force may cause them to shift, resulting in a change in the angle between the insulator string and the conductor, and thus generating lateral tension. However, in this embodiment, through the cooperation of the lifting mechanism 2 and the tensioning assembly 3, that is, the conductor hook 21 lifts the conductor and then is hoisted by the tensioning assembly 3, the two conductor hooks 21 exert the same tension on the conductor, avoiding the situation of uneven force and lateral tension during the lifting of the insulator string. In addition, the tripod formed by the three support rods 11 has stability and can well support the weight of the conductor.

[0064] Example 2

[0065] Based on Example 1, such as Figure 1 As shown, in this embodiment, a current transformer 7 is installed between the two conductor hooks 21. Specifically, during the tension pole modification process, the line current needs to be monitored in real time to ensure that the current of the modified line is within a safe range. The current transformer provides a standardized current signal for the measuring equipment, facilitating accurate measurement and recording.

[0066] like Figure 1 and Figure 2 As shown, the two support rods 11 connected to the second fixed foot 122 each 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 by 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 and supports the current transformer 7. Additionally, the sliding rod 8 is connected to the sliding block 22 to achieve synchronous rising or falling of the wire hook 21 and the current transformer 7. Therefore, when the wire hook 21 lifts the wire, the wire also passes through the current transformer 7. At this time, the current transformer 7 converts the high current to a low current, facilitating measurement with a standard ammeter. The current transformer 7 rises or falls synchronously with the wire hook 21.

[0068] Example 3

[0069] Based on Example 1, such as Figure 2 and Figure 4 As shown, the threads of the bidirectional lead screw 51 will gradually wear down, thus weakening its self-locking ability. To further improve the performance of the fastener 5, this embodiment provides another form of fastener: the fastener 5 consists of a ratchet wrench 54, a threaded cylinder 55, and a threaded rod 56. There are two threaded rods 56, and each of the two threaded rods 56 is connected to a corresponding second fixing foot 122. The threaded cylinder 55 is located between the two threaded rods 56 and is threadedly connected to each of the two threaded rods 56. The ratchet wrench 54 is mounted on the threaded cylinder 55 and is used to drive the threaded cylinder 55 to rotate.

[0070] The ratchet wrench 54 includes a ratchet 541 and a pawl 542 that can rotate in one direction. The unidirectional drive is achieved by the meshing of the pawl 542 with the gear ring of the ratchet 541. The specific working process of the fixing part 5 is as follows: the ratchet wrench 54 drives the threaded cylinder 55 to rotate in one direction. The internal threads at both ends of the threaded cylinder 55 have opposite directions and are respectively connected to the corresponding threads of the two threaded rods 56. When the threaded cylinder 55 rotates, since the second fixing foot 122 has a certain engagement with the crossbar before the fixing part 5 is activated, 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 with the corresponding connected crossbars. Due to the structure of the ratchet handle itself, the threaded cylinder 55 is locked after rotation, which finally ensures 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 change direction, such as... Figure 6As shown, the variable-direction ratchet wrench 54 can be equipped with two types of pawls 542. These pawls 542 are located on the left and right sides inside the ratchet handle 54 and are oriented in different directions. Both pawls 542 engage with the ratchet 541 via springs 544. A switch 543, shaped like a cam, is positioned between the two pawls 542. When the switch 543 rotates to one side and engages with the left pawl 542, that pawl 542 moves away from the ratchet 541, and the other pawl 542, under the action of the spring 544, engages with the ratchet 541 to achieve unidirectional rotation. Conversely, when the switch 543 rotates to the other side and engages with the right pawl 542, the left pawl 542 engages with the ratchet 541, completing the direction change. It should be noted that the resistance force of the switch 543 on the pawl 542 is greater than the elastic force of the spring 544. The switch 543 will not rotate autonomously under normal conditions and can only rotate under manual drive.

[0072] After the pawl 542 changes direction, the ratchet wrench 54 drives the threaded cylinder 55 to rotate in the opposite direction. The threaded cylinder 55 drives the two threaded rods 56 to move in opposite directions, thereby moving the two second fixed feet 122 away from the crossbar to achieve loosening.

[0073] Example 4

[0074] Other examples Figure 5 As shown, based on Embodiment 1, this embodiment is configured as follows: the tensioning assembly 3 includes a support belt 32, a tensioning wheel 34, a handle 33, a drum 35, and a ratchet and pawl mechanism; the tensioning wheel 34 is located at the connecting block, the drum 35 and the ratchet and pawl mechanism are mounted on the support rod 11 connected to the first fixed foot 121, one end of the support belt 32 is connected to the sliding block 22, and the other end passes around the tensioning wheel 34 and is connected to the drum 35, the handle 33 is mounted on the outside of the drum 35, and the ratchet and pawl mechanism (not shown in the figure) is mounted on the drum 35 to limit the unidirectional rotation of the drum 35. It can be seen that the ratchet and pawl mechanism is an existing structure, and will not be described in detail here.

[0075] The specific process is as follows: when the handle 33 is turned, the 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. The ratchet and pawl prevent the drum from rotating in the opposite direction, and the tightening wheel changes the direction of the force, reduces friction, and improves the transmission efficiency. Finally, the wire hook 21 smoothly lifts the wire.

[0076] Example 5

[0077] Based on Example 1, such as Figure 1As shown, the tensioning assembly 3 also has another form: the tensioning assembly 3 includes a tensioner 31, which is connected to the sliding block 22 via a support belt 32. The process of lifting the conductor is as follows: two conductor hooks 21 hook the conductor, and the tensioner 31 pulls the sliding block 22 taut through the support belt 32. The tensioner 31 generates a continuous pulling force through its mechanical structure, gradually tightening the support belt 32 to a predetermined tension. This process avoids the inefficiency and instability of manual pulling, ensuring that the conductor remains taut during the lifting process. It is known that the support belt 32 has high strength and wear resistance, and can stably bear the weight of the conductor. The tensioner in this embodiment is an existing design, so it will not be described in detail.

[0078] Example 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. 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 Example 1, such as Figure 2 and Figure 4 As shown, the configuration is as follows: the first fixing foot 121 and the two second fixing feet 122 are rotatably connected to the corresponding support rod 11; an angle adjustment assembly 4 is provided between the first fixing 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 fixing foot 121 can rotate omnidirectionally and has strong mobility. Specifically, the angle adjustment assembly 4 includes a drive frame 41, a first lead screw 42, a limiting rod 44, and a moving block 45. The drive frame 41 is installed on top of the first fixing foot 121; the first lead screw 42 is laterally rotatably arranged inside the drive frame 41, and one end of the first lead screw 42 is connected to a first crank 43; the limiting rod 44 is arranged parallel to the first lead screw 42; the moving block 45 is threadedly connected to the first lead screw 42 and slidably connected to the limiting rod 44, and the bottom of the moving block 45 is rotatably connected to the corresponding support rod 11.

[0081] The drive frame 41 provides support for the first lead screw 42 and the limiting rod 44. In this embodiment, there are two limiting rods 44, which are placed on both sides of the first lead screw 42. The moving block 45 is provided with a threaded hole so as to be threadedly connected to the first lead screw 42. In addition, the moving block 45 is also provided with a sliding hole so that the two limiting rods 44 can 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 limit of the limit 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 connected to the two second fixed feet 122 respectively rotate. At this time, the wire hook 21 located on the two support rods 11 rotates counterclockwise.

[0083] Conversely, when the first crank 43 drives the first lead screw 42 to rotate in the opposite direction, the moving block 45 begins to move horizontally to the right under the limit of the limit 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 rotates horizontally to the right. Due to the fixation of the second fixed foot 122, the two support rods 11 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.

[0084] Finally, by adjusting the angle of the wire hook 21, the wire can be accurately inserted 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, after lifting the wire, adjusting the angle of the wire hook 21 can securely fasten the wire in the space of the wire hook 21, preventing the wire from slipping and causing safety hazards.

[0085] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
