Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage transmission line erection, specifically, it relates to an ultra-high voltage line traction slip device. Background Technology

[0002] Currently, in the high-altitude erection of high-voltage transmission lines, insulator strings are used to suspend pulley blocks at high altitudes. Then, traction equipment is used to pull multiple parallel high-voltage transmission lines, allowing them to pass smoothly through predetermined nodes at high altitudes via the pulley blocks. However, when passing through these nodes, wind and other forces can cause the high-voltage transmission lines to shake or deviate, leading to some lines veering off the pulley blocks, affecting transmission efficiency, and potentially causing damage. In existing methods, the ends of the high-voltage transmission lines are connected to traction equipment, which is then controlled to move the lines at high altitudes. However, during traction, the connection between the high-voltage transmission lines and the traction equipment is prone to detachment when encountering resistance. Utility Model Content

[0003] This utility model provides an ultra-high voltage line traction slip device to ensure that parallel high voltage transmission lines pass smoothly through the pulley block, avoid the high voltage transmission lines from shaking or deviating from the pulley block during the erection process, improve the erection efficiency of high voltage transmission lines, and ensure the connection strength between the traction equipment and the high voltage transmission line.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-voltage power line traction and sliding device includes a traction and sliding guide plate fixed to a traction cable. The traction and sliding guide plate is connected to a high-voltage line holding mechanism via two connecting arms. A high-voltage line clamping mechanism is installed on the high-voltage line holding mechanism. Multiple high-voltage lines pass through the high-voltage line holding mechanism side by side, and these high-voltage lines are fastened to the high-voltage line holding mechanism via the high-voltage line clamping mechanism. Multiple guide teeth are installed at one end of the traction and sliding guide plate away from the high-voltage line holding mechanism. These guide teeth are spaced laterally along the traction and sliding guide plate.

[0006] Furthermore, an arc-shaped limiting groove is constructed at one end of the traction guide plate near the high-voltage line holding mechanism, and wire-passing holes are constructed on both sides of the traction guide plate. The two wire-passing holes are respectively connected to the two ends of the arc-shaped limiting groove. The middle part of the traction cable is assembled in the arc-shaped limiting groove to form a fixing part, and the two ends of the traction cable pass through the two wire-passing holes to form two traction parts. Multiple tightening buckles are connected to the traction guide plate, and these tightening buckles are fastened to the outside of the fixing part.

[0007] Furthermore, the traction guide plate includes an upper guide plate body and a lower guide plate body arranged opposite to each other. A first connecting ear is constructed on both sides of the upper guide plate body, and a second connecting ear is constructed on both sides of the lower guide plate body. Each connecting arm is installed between the corresponding first connecting ear and second connecting ear and is fixed by multiple fixing bolts.

[0008] Furthermore, multiple connecting holes are provided at the end of the traction guide plate away from the high-voltage line holding mechanism. These connecting holes are spaced apart along the extension direction of the arc-shaped limiting groove. First assembly grooves are provided on the upper guide plate body and the lower guide plate body at both ends of the connecting holes. First notches are provided on the upper guide plate body and the lower guide plate body at each of the first assembly grooves. The tightening buckle includes an elastic U-shaped buckle with connecting rings at both ends. The elastic U-shaped buckle is fastened to the outer edge of the upper guide plate body and the lower guide plate body and tightens the fixing part. The two connecting rings are respectively assembled in two opposite first assembly grooves. The fastening bolt passes through the connecting hole and is threadedly fastened to the two connecting rings.

[0009] Furthermore, multiple assembly ports are provided on the lower guide plate body at transverse intervals, one end of each guide tooth is assembled at the corresponding assembly port, and the guide tooth is connected to the upper guide plate body.

[0010] Furthermore, the guide tooth includes a guide tooth body, one end of which is a connecting end, which is fitted into the assembly port, and the other end of the guide tooth body is a guide end, which is bent upward.

[0011] Furthermore, the width of the connecting end is smaller than the width of the assembly opening. A vertical shaft is fixed on the connecting end. An assembly hole is opened on the upper guide plate body. A second assembly groove communicating with the assembly hole is opened at the upper end of the upper guide plate body. The vertical shaft moves through the assembly hole and out of the second assembly groove. A connecting spring is fitted on the vertical shaft. The two ends of the connecting spring are respectively connected to the upper end face of the vertical shaft and the second assembly groove.

[0012] Furthermore, the high-voltage line holding mechanism includes a transverse line holding seat with fixed ears on both sides, and the two connecting arms are respectively connected and fixed to the two fixed ears. Multiple fixing holes are spaced apart on the transverse line holding seat along the arrangement direction of the high-voltage lines, and the end of each high-voltage line passes through the corresponding fixing hole.

[0013] Furthermore, the high-voltage wire harness tightening mechanism includes two mounting plates symmetrically arranged at both ends of the transverse wire holder. Each mounting plate has multiple wire harness nozzles, which correspond one-to-one with the wire fixing holes. Multiple second notches are evenly opened along the circumference of each wire harness nozzle, and a wire harnessing channel communicating with the wire fixing hole is formed inside the wire harness nozzle. Multiple adapter holes are spaced apart along the arrangement direction of the high-voltage wires on the transverse wire holder. A connecting screw passes through the corresponding adapter hole and the two mounting plates, and a locking nut is threaded onto the connecting screw.

[0014] Furthermore, the diameter of the wire harness nozzle decreases from the mounting plate toward the wire fixing hole, and adjustment ports are respectively constructed at both ends of the wire fixing hole. The diameter of the adjustment ports increases outward from the end of the wire fixing hole, and the end of the wire harness nozzle extends into the adjustment port.

[0015] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, are as follows: The traction cable is connected to the traction device, which pulls the cable, causing it to move the traction guide plate towards the pulley block. As the guide plate approaches the pulley block, multiple guide teeth correspond one-to-one with the pulleys. During the accurate passage of these guide teeth through the pulley block, the guide plate does not experience significant deviation, ensuring the high-voltage line holding mechanism can accurately pass through the pulley block. This allows multiple parallel high-voltage lines to pass through their respective pulleys, preventing vibration or skew in the high-voltage lines and avoiding damage caused by friction between the high-voltage lines and other components of the pulley block besides the pulleys. Furthermore, the high-voltage line clamping mechanism secures multiple high-voltage lines to the high-voltage line holding mechanism, preventing them from detaching and ensuring smooth construction. In summary, this utility model can ensure that parallel high-voltage transmission lines pass smoothly through the pulley block, avoid the high-voltage transmission lines from shaking or deviating from the pulley block during the erection process, improve the erection efficiency of high-voltage transmission lines, and ensure the connection strength between the traction equipment and the high-voltage transmission lines.

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] This utility model discloses a traction slippage device for ultra-high voltage lines, such as... Figure 1-10 As shown, the device includes a traction guide plate 100, a high-voltage line holding mechanism 500, a high-voltage line tightening mechanism 600, two connecting arms 400, and multiple guide teeth 200. The traction guide plate 100 is fixed to the traction cable 300 and connected to the high-voltage line holding mechanism 500 via the two connecting arms 400. The high-voltage line tightening mechanism 600 is mounted on the high-voltage line holding mechanism 500, through which multiple high-voltage lines pass side-by-side and are tightened. The multiple guide teeth 200 are installed at the end of the traction guide plate 100 away from the high-voltage line holding mechanism 500 and are spaced laterally along the traction guide plate 100. The working principle and advantages of this utility model are as follows: The traction cable 300 is connected to the traction equipment, which pulls the traction cable 300, causing it to move the traction guide plate 100 towards the pulley group. When the traction guide plate 100 approaches the pulley group, multiple guide teeth 200 correspond one-to-one with multiple pulleys of the pulley group. During the process of these guide teeth 200 accurately passing through the pulley group, the traction guide plate 100 will not experience significant deviation, thus ensuring that the high-voltage line holding mechanism 500 can accurately pass through the pulley group. This allows multiple parallel high-voltage lines to pass through each pulley of the pulley group, preventing the high-voltage lines from shaking or deviating, and also preventing damage caused by friction between the high-voltage lines and other components of the pulley group besides the pulleys. This utility model uses a high-voltage line tightening mechanism 600 to tighten multiple high-voltage lines onto the high-voltage line holding mechanism 500, thereby preventing the high-voltage lines from detaching from the high-voltage line holding mechanism 500 and ensuring the smooth progress of the erection work. In summary, this utility model can ensure that parallel high-voltage transmission lines pass smoothly through the pulley block, avoid the high-voltage transmission lines from shaking or deviating from the pulley block during the erection process, improve the erection efficiency of high-voltage transmission lines, and ensure the connection strength between the traction equipment and the high-voltage transmission lines.

[0031] As a preferred embodiment of this utility model, such as Figure 2-6As shown, an arc-shaped limiting groove 112 is constructed at one end of the traction guide plate 100 near the high-voltage line holding mechanism 500. Wire-passing holes 111 are constructed on both sides of the traction guide plate 100, and the two wire-passing holes 111 are respectively connected to the two ends of the arc-shaped limiting groove 112. The middle part of the traction cable is fitted into the arc-shaped limiting groove 112. The middle part of the traction cable is a fixing part 302, and the two ends of the traction cable respectively pass through the two wire-passing holes 111, forming two traction parts 301 at each end. These two traction parts 301 are connected to the traction equipment. Furthermore, multiple fastening buckles are connected to the traction guide plate 100. These fastening buckles are fastened to the outside of the fixing part 302, thereby securing the fixing part 302 within the arc-shaped limiting groove 112. This ensures that when the traction equipment pulls the two traction parts 301, the fixing part 302 of the traction cable will not slide within the arc-shaped limiting groove 112, thus improving the stability of the traction guide plate 100. Furthermore, in this embodiment, an arc-shaped limiting groove 112 is used to fix the arc-shaped fixing part 302, thereby increasing the contact area between the fixing part 302 and the traction guide plate 100. When the fixing part 302 is subjected to tension, the two components of the tension are the tangential component of the arc-shaped limiting groove 112 and the radial component of the arc-shaped limiting groove 112. The radial component of the arc-shaped limiting groove 112 is canceled by the traction guide plate 100, and the tangential component of the arc-shaped limiting groove 112 is canceled by the tightening buckle. Moreover, with the fastening of multiple tightening buckles, the fixing part 302 and the arc-shaped limiting groove 112 are fastened at multiple points, which further avoids relative movement between the fixing part 302 and the traction guide plate 100 when subjected to tension.

[0032] As a preferred embodiment of this utility model, such as Figure 5 As shown, the traction guide plate 100 includes an upper guide plate body 101 and a lower guide plate body 108, which are arranged vertically opposite each other. First connecting ears 102 are respectively constructed on both sides of the upper guide plate body 101, and second connecting ears 109 are respectively constructed on both sides of the lower guide plate body 108. Each connecting arm 400 is installed between the corresponding first connecting ear 102 and second connecting ear 109, and multiple fixing bolts fix the corresponding first connecting ear 102, second connecting ear 109, and connecting arm 400. In this embodiment, multiple connecting holes 103 are provided at the end of the traction guide plate 100 away from the high-voltage line holding mechanism 500. These connecting holes 103 are spaced apart along the extension direction of the arc-shaped limiting groove 112. A first mounting groove 104 is formed on the upper guide plate body 101 above the connecting hole 103, and another first mounting groove 104 is formed on the lower guide plate body 108 below the connecting hole 103. A first notch 105 is formed on both the upper guide plate body 101 and the lower guide plate body 108 at each of the first mounting grooves 104. Figure 3 As shown, the fastening buckle includes an elastic U-shaped buckle 113 and two connecting rings 114. The two connecting rings 114 are respectively constructed at both ends of the elastic U-shaped buckle 113. The elastic U-shaped buckle 113 is fastened to the outer edge of the upper guide plate body 101 and the lower guide plate body 108. The elastic U-shaped buckle 113 fastens the fixing part 302 of the traction cable. Moreover, the two connecting rings 114 are respectively assembled in two opposite first mounting grooves 104. The fastening bolts 115 pass through the connecting holes 103 and are threadedly fastened to the two connecting rings 114, so that each connecting ring 114 is fastened in the corresponding first mounting groove 104.

[0033] As a preferred embodiment of this utility model, such as Figure 4 , 5 As shown, a plurality of mounting openings 110 are provided on the lower guide plate body 108. These mounting openings 110 are arranged at intervals along the lateral direction of the lower guide plate body 108. One end of each guide tooth 200 is fitted into the corresponding mounting opening 110, and the guide tooth 200 is connected to the upper guide plate body 101. Specifically, the guide tooth 200 includes a guide tooth body. One end of the guide tooth body is a connecting end 204, which is fitted into the mounting opening 110. The other end of the guide tooth body is a guide end 201, which is bent upward to facilitate smooth insertion of the guide end 201 into the pulley of the corresponding pulley group. In this embodiment, the width of the connecting end 204 is smaller than the width of the mounting opening 110. A vertical shaft 202 is fixed on the connecting end 204. A mounting hole 106 is provided on the upper guide plate body 101, and a second mounting groove 107 is provided at the upper end of the upper guide plate body 101. The second mounting groove 107 communicates with the upper end of the mounting hole 106. In this embodiment, the vertical shaft 202 extends movably through the mounting hole 106 and out of the second mounting groove 107. A connecting spring 203 is fitted on the vertical shaft 202, and both ends of the connecting spring 203 are connected to the upper end faces of the vertical shaft 202 and the second mounting groove 107, respectively. The working principle and advantages of this embodiment are as follows: Since the width of the connecting end 204 is smaller than the width of the mounting opening 110, when there is a small positional deviation between the traction guide plate 100 and the pulley group, the guide end 201 of the guide tooth 200 extends to the corresponding pulley. Under the constraint of the pulley, the guide tooth 200 undergoes a certain elastic twisting along the axis of the vertical shaft 202, thereby facilitating the guide tooth 200 to pass through the pulley and guiding the traction guide plate 100 through the pulley group. Moreover, the guide tooth 200 can also undergo axial elastic movement along the vertical shaft 202 to compensate for the vertical deviation between the guide tooth 200 and the pulley, ensuring that the guide tooth 200 passes smoothly through the pulley.

[0034] As a preferred embodiment of this utility model, such as Figure 7-10As shown, the high-voltage wire holding mechanism 500 includes a transverse wire holding base 501, with fixing ears 502 respectively constructed on both sides of the transverse wire holding base 501. The two connecting arms 400 are respectively connected and fixed to the two fixing ears 502. Multiple wire fixing holes 503 are provided on the transverse wire holding base 501, and these wire fixing holes 503 are spaced apart along the arrangement direction of the high-voltage wires. The end of each high-voltage wire passes through the corresponding wire fixing hole 503. The high-voltage wire tightening mechanism 600 of this embodiment includes two mounting plates 601, which are symmetrically arranged at both ends of the transverse wire holding base 501. Multiple wire tightening nozzles 602 are constructed on each mounting plate 601, and these wire tightening nozzles 602 are corresponding one-to-one with the wire fixing holes 503. In this embodiment, multiple second notches 604 are evenly provided circumferentially on the cable tie nozzle 602. A cable tie channel 603 communicating with the cable fixing hole 503 is formed inside the cable tie nozzle 602. Multiple adapter holes 505 are provided on the transverse cable holder 501. These adapter holes 505 are spaced apart along the arrangement direction of the high-voltage wires. The connecting screw 605 passes through the corresponding adapter hole 505 and the two mounting plates 601. A locking nut 606 is threaded onto the connecting screw 605. The diameter of the cable tie nozzle 602 decreases from the mounting plate 601 toward the cable fixing hole 503. An adjustment port 504 is constructed at both ends of each cable fixing hole 503. The diameter of each adjustment port 504 increases outward from the end of the cable fixing hole 503, and the end of the cable tie nozzle 602 extends into the adjustment port 504. The working principle and advantages of this embodiment are as follows: By rotating the connecting screw 605, the distance between the two mounting plates 601 gradually decreases. This increases the length of the wire harness nozzle 602 extending into the adjustment port 504. Under the constraint of the adjustment port 504, the wire harnessing channel 603 of the wire harness nozzle 602 gradually narrows, thereby gradually tightening the high-voltage wire passing through the wire harnessing channel 603. The strength of the wire harness nozzle 602 in tightening the high-voltage wire is adjusted according to the length of the wire harness nozzle 602 extending into the adjustment port 504.
