[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0040] Example 1

[0041] 1-2 , which is a first embodiment of the present invention, provides an auxiliary tool for power transmission line repair work under low visibility conditions, including a conductor 100, an adjustment assembly 200 for adjusting the sag of the conductor 100, which includes a clamping member 201 for clamping the conductor 100, a tension detection member 203 provided at the traction end of the clamping member 201 for detecting the tension of the conductor 100, an electric hoist 204 provided at the traction end of the tension detection member 203 for pulling the tension detection member 203, and a data receiving controller 205 wirelessly connected to each component; a connecting rod assembly 300, mounted on the clamping member 201, for controlling the clamping member 201 to clamp the conductor 100; and a limit assembly 400, for limiting the movement direction of the connecting rod assembly 300.

[0042] Among them, after the emergency repair work of the transmission line reaches the sag adjustment stage, the staff clamps and fixes the conductor 100 through the clamping part 201, and then connects the clamping part 201, the tension detection part 203 and the electric hoist 204 in sequence through the connecting part 202. After checking that everything is correct, the staff can control the electric hoist 204 to tighten through the data receiving controller 205. During the tightening process of the conductor 100, the tension detection part 203 can measure the current tension value of the conductor 100 and transmit the data to the data receiving controller 205. Before the tension of the conductor 100 reaches the preset value, the electric hoist 204 will automatically and slowly tighten. When the tension of the conductor 100 reaches the preset value, the alarm on the data receiving controller 205 will sound, and the electric hoist 204 will stop tightening, thereby solving the problem that the field of vision is affected by the external environment, resulting in the staff being unable to perform sag adjustment work on multiple conductors at the same time.

[0043] Furthermore, both ends of the tension detector 203 are connected to connectors 202, which are respectively connected to the clamping member 201 and the electric hoist 204. The data receiving controller 205 includes a display screen for receiving information from the tension detector 203 and controlling the operation of the electric hoist 204. The clamping member 201 includes an upper clamping plate 201a and a lower clamping plate 201b, with the conductor 100 positioned between the upper and lower clamping plates 201a and 201b. Clamping pads are fixedly connected to the opposing surfaces of the upper and lower clamping plates 201a and 201b.

[0044] Specifically, the connecting member 202 is preferably a shackle, so multiple components can be quickly assembled and disassembled with high efficiency.

[0045] The upper clamping plate 201a and the lower clamping plate 201b can increase the friction with the wire 100 through the clamping pad, thereby improving the firmness of the connection. The clamping pad is preferably made of rubber material.

[0046] In addition, the tension detection component 203 can realize many-to-one transmission and reception with the data receiving controller 205, that is, multiple tension detection components 203 are paired with one data receiving controller 205, which can realize sag adjustment of multiple wires at the same time, ensuring that the sag deviation of the tightening operation is less than the preset range. Secondly, the tension detection component 203, the electric hoist 204 and the data receiving controller 205 are all equipped with wireless modules, thereby realizing wireless transmission of data and improving the efficiency of the operation.

[0047] The tension detection component 203 model is F9204, made of alloy steel, suitable for measuring tension with a range of 0...1t to 0...40t. It has an integrated amplifier, is lighter in weight and higher in strength.

[0048] The data receiving controller 205 uses a capacitive touch screen to complete key operations and sensor alarm data settings. It has an alarm screen display, alarm sound prompts and flashing alarm lights. It can remotely control the standby and wake-up of the tension detection component 203 and the electric hoist 204. The communication distance is greater than 150 meters in an open area. It has a built-in 12.6V / 18Ah lithium battery.

[0049] Example 2

[0050] 2-5 , which is a second embodiment of the present invention, is different from the previous embodiment in that it further includes a connecting rod assembly 300 including a pressure plate 301, the lower end of the pressure plate 301 is rotatably set on the lower clamping plate 201b, and a pressure groove 302 is opened on the side of the pressure plate 301 facing the upper clamping plate 201a, and a pressure rod 303 is slidably connected inside the pressure groove 302, and the pressure rod 303 is fixed on the upper clamping plate 201a. The upper end of the pressure plate 301 is rotatably connected to a first connecting rod 304. A positioning plate 305 is provided at the end of the first connecting rod 304 away from the pressure plate 301. The lower end of the positioning plate 305 is fixed to the lower clamping plate 201b. A sliding groove 305c is horizontally defined on the surface of the positioning plate 305. A positioning shaft 306 is slidably connected within the sliding groove 305c. The positioning shaft 306 is rotatably mounted on the first connecting rod 304. A traction rod 307 is rotatably connected to the positioning shaft 306, and the traction rod 307 is plugged into the connector 202. A guide groove 305a is defined on the side of the positioning plate 305 facing the upper clamping plate 201a. A guide rod 305b is slidably connected within the guide groove 305a and is fixed to the upper clamping plate 201a. The limiting assembly 400 includes a limiting gear 401. The end of the positioning shaft 306, which is remote from the first connecting rod 304, extends out of the sliding slot 305c and is rotatably connected to the limiting gear 401. The lower end of the limiting gear 401 engages with a limiting rack 402, which is fixed to the outside of the positioning plate 305. A first engaging block 401b is fixed to the side of the limiting gear 401 facing the positioning shaft 306. A second engaging block 401d corresponding to the first engaging block 401b is disposed within the positioning shaft 306. The first and second engaging blocks 401b and 401d each have engaging grooves on their opposing surfaces. The end of the second engaging block 401d, which is remote from the first engaging block 401b, is rotatably connected to a one-way bearing 401e, which is mounted within the positioning shaft 306.

[0051] As shown in Figure 3, when the traction rod 307 is pulled by the connecting member 202, the traction rod 307 drives the first connecting rod 304 connected coaxially to move horizontally, and the first connecting rod 304 drives the pressure plate 301 connected to the rotation to rotate. During the rotation, the pressure plate 301 will squeeze the pressure rod 303 through the pressure groove 302. Since the guide groove 305a can guide the movement direction of the guide rod 305b, the movement direction of the upper clamping plate 201a fixed to the guide rod 305b can be further guided, so that the pressure rod 303 drives the fixed upper clamping plate 201a to squeeze the wire 100 downward along the pre-guided movement direction, thereby clamping and tightening the wire 100. By adopting this clamping method, the greater the traction force applied to the traction rod 307, the greater the clamping force applied, and the fixation is more secure. Compared with traditional bolt fixing, the clamping is more convenient and stable.

[0052] In addition, as shown in Figure 3-4, when the traction rod 307 moves, it drives the coaxially connected positioning shaft 306 to move. The positioning shaft 306 is connected to the limit gear 401, so it drives the limit gear 401 to rotate along the engaged limit rack 402. Referring to Figure 5, at this time, the second bite block 401d and the first bite block 401b are engaged as a whole through the bite groove, so the limit gear 401 synchronously drives the second bite block 401d to rotate, and the second bite block 401d simultaneously drives the fixedly connected one-way bearing 401e to rotate, thereby limiting the rotation direction of the limit gear 401 and making it non-reversible. In cooperation with the limit rack 402, the movement direction of the limit gear 401 is restricted. Therefore, the coordinated use of the connecting rod assembly 300 and the limit assembly 400 can achieve self-locking during the clamping process and ensure the stability of the clamping force.

[0053] Example 3

[0054] Referring to Figures 5-7 , a third embodiment of the present invention further provides an auxiliary tool for power transmission line repair work in low-visibility conditions. The tool comprises a separation assembly 500 mounted on the end of a limit gear 401 away from the positioning shaft 306. The separation assembly 500 comprises a separation cylinder 501 slidably mounted on the outside of the limit gear 401. A separation rod 401c slidably connected to the middle of the limit gear 401 and fixed to the separation cylinder 501 is used to push a second engaging block 401d to move. The second engaging block 401d comprises a telescopic cylinder and a telescopic rod, with a compression spring sleeved on the outside of the telescopic rod.

[0055] After the tension of the conductor 100 is adjusted, when the conductor 100 needs to be removed, referring to Figure 5-6, the staff can use a tool to knock the separation cylinder 501 to make the separation cylinder 501 shrink into the limit gear 401. During the shrinkage process, the separation cylinder 501 will drive the fixed separation rod 401c to push the second bite block 401d to shrink. Specifically, the second bite block 401d is composed of a telescopic cylinder and a telescopic rod. The separation rod 401c can separate the second bite block 401d and the first bite block 401b by squeezing the telescopic rod into the telescopic cylinder, thereby contacting the one-way rotation constraint of the limit gear 401, and the staff can quickly separate the conductor 100.

[0056] Secondly, the compression spring applies thrust to the telescopic rod, so that the second bite block 401d and the first bite block 401b are automatically engaged and connected, so that the limit gear 401 has the one-way limit function again, thereby achieving repeated clamping of the wire 100.

[0057] The end of the separation cylinder 501 away from the limit gear 401 is rotatably connected to the adjusting cover 502, and the end of the adjusting cover 502 facing the separation cylinder 501 is fixed with a turntable 502a, and a rotation groove 502b is provided on the surface of the turntable 502a. The inner wall of the separation cylinder 501 is slidingly connected to the limit block 503, and the inner wall of the separation cylinder 501 is provided with a groove to accommodate the limit block 503 to slide out and resist the limit gear 401, and a driving rod is provided on the outside of the limit block 503 to extend into the rotation groove 502b.

[0058] Since work needs may require pulling multiple wires 100 at a time, the wires 100 may be affected by external factors such as wind during the pulling process, causing the adjustment components 200 to collide with each other, resulting in the separation of the second bite block 401d and the first bite block 401b, causing the wires 100 to detach.

[0059] 6-7, the staff rotates the adjustment cover 502 so that the adjustment cover 502 drives the turntable 502a to rotate to a preset angle, for example, 15°-30°, so that the rotation groove 502b drives the limit block 503 to retract or extend through the driving rod. When the limit block 503 retracts, the separation cylinder 501 can slide into the limit gear 401 to release the limit. When the limit block 503 extends, it will resist the limit gear 401, so that the separation cylinder 501 cannot slide into the limit gear 401, thereby solving the problem of false triggering caused by the above-mentioned collision.
