Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line towers, and in particular to a line routing back to a tower position device and a use method thereof. Background Art

[0002] A transmission line tower is a structure that supports the conductors and lightning conductors of high-voltage or ultra-high-voltage overhead power transmission lines. It is generally divided into five types according to its shape: wine glass type, cat head type, upper type, dry type and barrel type. According to its use, it can be divided into: tension tower, straight tower, corner tower, transposition tower, terminal tower and spanning tower.

[0003] For example, a tension-resistant transmission tower disclosed in announcement number CN111769501B includes a tower body, a fixing frame, and a line plate. The inner side of the fixing frame is embedded in the outer surface of the tower body, and the top of the line plate is connected to the bottom of the fixing frame by welding. The bolt is rotated, and the positioning block drives the moving block to move downward under the meshing of the screw rod and the bite groove, so that the clamping plate is close to the surface of the transmission line, so as to prevent the transmission line from being blown away from the line plate by the wind.

[0004] And as the AC transmission line cross-over structure disclosed in announcement number CN107394737B, this technology includes a first line and a second line of the same voltage level, both of which are three-phase single-circuit transmission lines. The two-circuit line phase lines of this technology sequentially change positions on the tension tower to ensure a safe distance and achieve cross-over. There is no need for overhead crossing or underground penetration, which can greatly reduce the land occupation. However, the above technology still has problems in use due to structural limitations:

[0005] When high-voltage wires are erected on transmission towers, insulator strings are often used to connect the high-voltage wires to the transmission towers. If the erected high-voltage wires are stretched and straightened, the high-voltage wires will expand and contract due to heat and cold, and the stretched high-voltage wires are very easy to break in winter. Therefore, in actual installation, the high-voltage wires need to be in a relaxed state. However, the erection components in the above-mentioned technology are vertically fixed, and the relaxed state of the high-voltage wires cannot be adjusted at a single transmission tower. Therefore, it is necessary to pull and pull at the same time on the ground and at a single transmission tower to relax the high-voltage wires in a single transmission tower. When adjusting the high-voltage wires in two transmission towers, the distance between the two transmission towers needs to be longer so that the high-voltage wire between the two towers can sag due to its own weight and be in a relaxed state. If the distance between the two transmission towers is short, the high-voltage wire between the two towers cannot sag due to its own weight, and the high-voltage wire needs to be pulled and relaxed between the two transmission towers, while maintaining the relaxed state of the high-voltage wire at a single transmission tower, which makes it difficult to adjust the high-voltage wire to a relaxed state. Summary of the invention

[0033] Step S4: Then repeat steps S2 and S3 at the other tower body, so that the other end of the wire body located in the middle of the two tower bodies is deflected and pushed toward one tower body, and the wire body located in the middle of the two tower bodies is arched in an N shape, so that the wire body is in a relaxed state, and then the upper end of the wire body is abutted against the third placement circular groove in turn, and the upper end arc block and the first rotating wheel are fixedly connected by bolts, the horizontal plate is fixedly connected to the limiting movable part, and the connecting long rod and the horizontal long rod are fixedly connected to the vertical slide rail, thereby completing the limiting of the wire body.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] The present invention pushes the connecting long rod to move downward at one tower body, and drives two insulator strings to rotate in the opposite direction and rotate toward the outside of the installation platform, so that the two ends of an electric wire body in the two insulator strings are deflected and pushed toward the outside of the installation platform, thereby allowing an electric wire body in the two insulator strings to arch in a U shape, so that only adjustment is required at a single tower body, and an electric wire body located at one tower body can be quickly adjusted to a relaxed state.

[0036] The present invention drives two insulator strings at one tower body to rotate in opposite directions, so that one end of a wire body located between the two tower bodies is deflected and pushed toward the other tower body, and then repeats the above operation at the other tower body, so that the other end of a wire body located between the two tower bodies is deflected and pushed toward one tower body, and a wire body located between the two tower bodies is arched in an N shape, and then, without considering the distance between the two tower bodies, a wire body is quickly adjusted to a relaxed state in the two tower bodies, and the relaxed state of a wire body at one tower body is maintained.

[0037] The present invention first places one end of a wire body in a first placement circular groove, and through the passive rotation of a first rotating wheel and a group of second rotating wheels, the wire body quickly passes through two insulator strings.

[0068] The limiting mechanism includes a vertical slide groove 19, a limiting moving member 20 and a fixed long rod 21.

Since a first magnetic block 31 and an inner wall of a vertical slide groove 19 are movably abutted, when the first magnetic block 31 is located in the vertical slide groove 19, the first magnetic block 31 squeezes the return spring 32;

[0072] The limiting mechanism also includes a second magnetic block 33, a third magnetic block 34 and a fourth magnetic block 35. Figure 5 , Attachment Figure 6 , Attachment Figure 7 and attached Figure 8 As shown, a second magnetic block 33 is fixedly connected to the other vertical end of a limiting movable member 20, a third magnetic block 34 is fixedly connected to the inner wall of a vertical slide groove 19, and a fourth magnetic block 35 is fixedly connected to the inner wall of another vertical slide groove 19. When the limiting movable member 20 moves upward, the friction block 29 is separated from the rotating shaft 27 until a first magnetic block 31 and a third magnetic block 34 are attracted with opposite poles, and a second magnetic block 33 and a fourth magnetic block 35 are attracted with opposite poles, so as to lock the limiting movable member 20.

[0073] Preferably, the limiting mechanism also includes a limiting long hole 36, a placement slot 37 and an upper arc block 38, a limiting long hole 36 is opened through an inner wall of a vertical slide groove 19, a first magnetic block 31 is movably sleeved in a limiting long hole 36, when the limiting moving member 20 moves downward, the first magnetic block 31 moves downward together with the limiting arc plate 28 until the limiting arc plate 28 is in contact with the rotating shaft 27, at this time, the first magnetic block 31 is located at the limiting long hole 36, and due to a first magnetic block 31 and a The inner walls of the vertical slide grooves 19 are movably opposed to each other, and the first magnetic block 31 squeezes the return spring 32. The elastic force of the return spring 32 after squeezing allows the first magnetic block 31 to move to the limit long hole 36, thereby locking the limit moving member 20; when the limit moving member 20 needs to be released, the first magnetic block 31 is pushed to move into the storage long hole 30, so that the first magnetic block 31 is located in the vertical slide groove 19, and the limit moving member 20 is pulled upward at the same time to release the lock of the limit moving member 20; as shown in the attached Fig.10 and attached Fig.11 As shown, a placement slot 37 is opened at the center of a lateral end of a position-limiting moving member 20, and the placement slot 37 is a prism slot structure, and an upper arc block 38 is arranged below a lateral end of a position-limiting moving member 20;

[0074] The limiting mechanism also includes a third placement circular groove 39, a vertical connecting rod 40 and a horizontal plate 41. A third placement circular groove 39 is opened at the lower end of an upper arc block 38. The upper end of an electric wire body 11 is set in two third placement circular grooves 39 on the same side. A vertical connecting rod 40 is fixedly connected to the upper end of an upper arc block 38, and the vertical connecting rod 40 is a prism rod body structure. A vertical connecting rod 40 is slidably sleeved in a placement through groove 37. The prism groove body structure of the placement through groove 37 and the prism rod body structure of the vertical connecting rod 40 are used to increase the friction between the placement through groove 37 and the vertical connecting rod 40 to prevent the vertical connecting rod 40 from automatically moving downward in the placement through groove 37 due to gravity. At the same time, a horizontal plate 41 is fixedly connected to the upper end of a vertical connecting rod 40, as shown in the attached Fig.19 and attached Fig. 20 As shown, when the wire body 11 completes the deflection movement, the upper arc block 38 is pushed to move downward, so that the upper end of the wire body 11 is located in the third placement circular groove 39, and with the cooperation of the first placement circular groove 7 of the first rotating wheel 6, the wire body 11 located at the insulator string 3 is limited, and at this time, the horizontal plate 41 is against the limit moving member 20;

[0075] Preferably, the limiting mechanism further includes a first limiting threaded hole 42, a second limiting threaded hole 43, a third limiting threaded hole 44, a fourth limiting threaded hole 45 and a fifth limiting threaded hole 46. A first limiting threaded hole 42 is provided on a transverse long rod 23. After the transverse long rod 23 completes the movement in the vertical slide rail 14, the screw is screwed into the first limiting threaded hole 42 and the first adjustment threaded hole 17 to fix the transverse long rod 23 to the vertical slide rail 14, thereby locking the middle-end pushing member 22. The two second limiting threaded holes 43 are respectively provided at both ends of the transverse end of a limiting moving member 20, and the two third limiting threaded holes 44 are respectively provided at both ends of a transverse plate 41. When it abuts against the limit moving part 20, the bolt is screwed into the second limit threaded hole 43 and the third limit threaded hole 44 to fix the horizontal plate 41 with the limit moving part 20, thereby locking the upper arc block 38; two groups of fourth limit threaded holes 45 are respectively opened in a circumferentially equidistant manner at the two ends of a first rotating wheel 6 away from the first placement circular groove 7, and two fifth limit threaded holes 46 are respectively opened at the two ends of an upper arc block 38 away from the third placement circular groove 39. When the upper arc block 38 is in contact with the upper end of the wire body 11, the bolt is screwed into the fourth limit threaded hole 45 and the fifth limit threaded hole 46 to fix the upper arc block 38 with the first rotating wheel 6, thereby locking the first rotating wheel 6.

[0076] In particular, the attached Fig.17 As shown, when the two insulator strings 3 rotate in opposite directions, the up-down position difference caused by the rotation of the two insulator strings 3 causes the push link 26 and the end adjacent to the insulator string 3 to move toward the outside of the mounting platform 2, and causes the two push links 26 to deflect to compensate for the up-down position difference. At the same time, the left-right position difference caused by the rotation of the two causes the two push long rods 25 to slide toward the outside of the mounting platform 2 to compensate for the left-right position difference, so that the limiting arc plate 28 moves with the insulator string 3 and maintains the friction block 29 and the rotating shaft 27 in a state of abutting each other.

[0077] The present invention can be explained by the following operation mode:

[0078] First, hold a wire body 11 and climb up from a climbing ladder 13 of a tower body 1 to the stop platform 12 below the installation platform 2, then place one end of the wire body 11 in a first placement circular groove 7, and push the wire body 11 toward a group of second rotating wheels 9 to move the wire body 11 to the second placement circular groove 10. At the same time, the passive rotation of a first rotating wheel 6 and a group of second rotating wheels 9 assists the wire body 11 to move to another first placement circular groove 7, as shown in the attached figure. Fig.21As shown, let one wire body 11 pass through two insulator strings 3, and repeat the above operation to pass the one wire body 11 through two insulator strings 3 of another tower body 1;

[0079] Then, the middle end pusher 22 is pressed at one of the tower bodies 1 to allow the horizontal long rod 23 to move downward in the vertical slide rail 14, as shown in the attached figure. Figure 3 , Attachment Fig.14 , Attachment Fig.15 and attached Fig.16 As shown, the middle-end pusher 22 drives the two limit moving members 20 to move downward in the vertical slide groove 19 by pushing the long rod 25 and the connecting rod 26. At the same time, because the first magnetic block 31 abuts against the inner wall of the vertical slide groove 19, when the limit moving member 20 drives the first magnetic block 31 to move downward to the limit long hole 36, the elastic force of the squeezed return spring 32 allows the first magnetic block 31 to move to the limit long hole 36, thereby locking the limit moving member 20. At this time, the friction block 29 of the limit arc plate 28 abuts against the rotating shaft 27 to prevent the two rotating shafts 27 and the two first rotating wheels 6 from rotating significantly.

[0080] And push the connecting rod 15 at the same tower body 1, so that the connecting rod 15 moves downward in the vertical slide rail 14, as shown in the attached Fig.17 and attached Fig.18 As shown, the connecting rod 15 drives the common connection point of the upper ends of the two rotating connecting rods 16 to move downward, and the lower ends of the two rotating connecting rods 16 move toward the outside of the installation platform 2, and drive the two insulator strings 3 to rotate in the opposite direction and rotate toward the outside of the installation platform 2, so that one end of a wire body 11 located between the two tower bodies 1 is deflected and pushed toward the other tower body 1, and at the same time, the connecting rod 15 drives the conveying platform 8 to move downward, so that a set of second rotating wheels 9 moves downward and away from a wire body 11, so as to avoid affecting the deflection movement of the wire body 11;

[0081] Then repeat the above operation at the other tower body 1, so that the other end of the wire body 11 located between the two tower bodies 1 is deflected and pushed toward one tower body 1, and then Fig. 22 As shown, a wire body 11 located between the two tower bodies 1 is arched in an N shape, so that the wire body 11 is in a relaxed state, and then the upper arc blocks 38 on the two tower bodies 1 are pushed downward in sequence, so that the upper end of the wire body 11 is abutted against the third placement circular groove 39, and a plurality of bolts are screwed into a plurality of threaded holes, so that the upper arc block 38 and the first rotating wheel 6 are fixedly connected, the horizontal plate 41 is fixedly connected to the limiting movable member 20, and the connecting long rod 15 and the horizontal long rod 23 are fixedly connected to the vertical slide rail 14, thereby completing the limiting of the wire body 11.
