Description

Technical Field

[0001] The present invention relates to the technical field of transmission tower cable fixing, and in particular to a transmission tower cable fixing device and a use method thereof. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] The prior art mostly adopts a transmission tower cable fixing device disclosed in the announcement number CN116706817B. This technology can make the end of the cable body subject to tension when the installed cable body encounters strong winds and other phenomena, and drive the fixing frame to slide along the opening direction of the slide slot to squeeze the damping spring. At the same time, through the movement of the cable body, the bottom cone frame and the top cone frame can be driven to rotate along the rotating shaft to buffer the impact force instantly received by the cable body to achieve protection. However, the above technology still has problems in use due to structural limitations: When the high-voltage cables are installed on two transmission towers by the two above-mentioned fixed devices, since the high-voltage cables will expand and contract with heat, the high-voltage cables between the two fixed devices are kept in a drooping and relaxed state to avoid the high-voltage cables from breaking due to thermal expansion and contraction when they are stretched straight. The end of the high-voltage cables that is in contact with the edge of the fixed devices is pulled downward by the high-voltage cables in a drooping state, as shown in the attached figure. Fig.13 As shown, the force contact surface between one end and the edge of the fixing device is only an edge of the fixing device, which makes the force contact surface of one end smaller, thereby causing a larger pressure at one end.

[0014] 2. According to the present invention, when the first block is located above the first vertical groove and moves downward, the wedge-shaped surface moves downward to abut against the upper edge of the first vertical groove, and the wedge-shaped surface abuts against the inner wall of the first vertical groove. Then, the first block continues to move downward until the wedge-shaped surface is located at the second fixed square hole. Under the elastic force of the second spring after extrusion, the wedge-shaped surface moves into the third movable square hole, and the left end of the first rack moves to the outside of the lower base member, thereby automatically locking the alignment state of the annular connector, avoiding rotational movement of the annular connector after alignment, and saving time for locking the annular connector.

When placing the high-voltage cable 45, the high-voltage cable 45 is sequentially placed between the two annular connecting members 9 and in the closed lower placement groove 4 and upper placement groove 5, and the high-voltage cable 45 located in an annular connecting member 9 is limited by the two limiting wheels 10, and the rotation setting of the limiting wheels 10 is used to facilitate the high-voltage cable 45 to be pulled into the lower placement groove 4; The lower base member 1 and the upper base member 2 are also provided with a driving mechanism, which is provided in the lower base member 1 and the upper moving member 3. The high-voltage cable 45 between the two lower base members 1 is as shown in FIG.

When the upper movable member 3 is in an initial state, the moving slider 12 is located at the top end of the connecting groove 11. At the same time, since a first magnetic block 13 is fixedly connected to the upper end of the moving slider 12, a second magnetic block 14 is fixedly connected to the top end of the connecting groove 11, and the second magnetic block 14 is attracted to the first magnetic block 13 by opposite poles, the upper movable member 3 is limited above the upper base member 2, so that the upper base member 2 and the upper movable member 3 can be pushed toward the lower base member 1 in sequence later.

In the process, the transverse push rod 43 pushes the first rack 37 to move into the active chamber 44, so that the second rack 38 moves into the active chamber 44, so that the left end of the first rack 37 is flush with the outer end surface of the first block 26, and the wedge surface 39 is flush with the outer end surface of the first block 26, and then the upper base member 2 is pulled upward, and the upper base member 2 moves the upper moving member 3 upward together by moving the slider 12, so as to bring the first block 26 and the second block 28 away from the lower base member 1, thereby completing the disassembly and assembly of the upper base member 2 and the upper moving member 3; and when the reset push plate 42 is released, the elastic force of the reset spring 41 is used to keep the transverse push rod 43 away from the first fixed square hole 29.

[0026] The present invention can be explained by the following operation mode: First, one end of the high-voltage cable 45 is passed through an annular connector 9, and the high-voltage cable 45 is placed in the lower placement groove 4, and then passed through another annular connector 9, and then the high-voltage cable 45 is placed on the lower base member 1, and then the second block 28 is placed in the second vertical groove 27, and the upper base member 2 is pushed downward until the lower end of the second block 28 abuts against the bottom of the second vertical groove 27, so that the lower placement groove 4 and the upper placement groove 5 are closed, and the upper and lower ends of the high-voltage cable 45 located on the lower base member 1 are limited; Then, the upper moving member 3 is pushed downward to separate the first magnetic block 13 and the second magnetic block 14, so that the upper moving member 3 drives the moving slider 12 to move downward in the connecting slide groove 11, and at the same time, the upper moving member 3 drives the first block 26 to move downward in the first vertical groove 18, until the lower end of the first block 26 abuts against the upper end of the pushing plate 25, so that the first block 26 drives the pushing plate 25 to move downward, and the pushing plate 25 drives the moving rack 20 to move downward through the vertical connecting rod 24, and the moving rack 20 squeezes the first spring 21. At the same time, due to the meshing transmission of the moving rack 20 and the driven gear 23, as shown in the attached figure Figure 2 and attached Figure 3 As shown in the figure, the driven gear 23, the rotating shaft 22 and the rotating long rod 8 are rotated clockwise, and the rotating long rod 8 drives the annular connecting member 9 to rotate from the lower end of the lower base member 1 to the upper end of the lower base member 1, until the center of the annular connecting member 9 is aligned with the center of the closed lower placement groove 4 and the upper placement groove 5, that is, as shown in the figure. Fig.14As shown, the high-voltage cable 45 between the annular connector 9 and the edge of the lower placement groove 4 is placed in a horizontal state to prevent the end of the high-voltage cable 45 from contacting the edge of the lower placement groove 4 when the end is under downward force; When the first block 26 is located above the first vertical groove 18 and moves downward, the wedge surface 39 of the second rack 38 is aligned with the upper edge of the first vertical groove 18 until the wedge surface 39 moves downward to abut against the upper edge of the first vertical groove 18. At this time, the upper edge of the first vertical groove 18 provides the wedge surface 39 with a vertical direction perpendicular to the wedge surface 39 and toward the adjacent Figure 5 At the same time, under the guidance of the guide groove 35, the second rack 38 and the wedge surface 39 only move toward the adjacent Figure 5 The reaction force can be decomposed into the Figure 5 The force component in the left direction moves the second rack 38 and the wedge-shaped surface 39 to the left through the force component to the left. At the same time, since the second rack 38 and the first rack 37 are meshed with the transmission gear 34, the first rack 37 moves to the right, and the first rack 37 and the second rack 38 respectively squeeze the two second springs 36. At this time, the first block 26 continues to move downward to make the wedge-shaped surface 39 abut against the inner wall of the first vertical groove 18. Then, the first block 26 continues to move downward until the wedge-shaped surface 39 is located at the second fixed square hole 30, the first rack 37 is located at the first fixed square hole 29, the second rack 38 is located at the second fixed square hole 30, and the first fixed square hole 29 is aligned with the first movable square hole 31, and the second fixed square hole 30 is aligned with the second movable square hole 32 and the third movable square hole 33. Figure 5 As shown, the second rack 38 moves to the right under the elastic force of the second spring 36 after being squeezed, so that the wedge-shaped surface 39 of the second rack 38 moves to the third movable square hole 33 of the second block 28 through the second fixed square hole 30, and the first rack 37 moves to the left under the elastic force of the second spring 36 after being squeezed, so that the left end of the first rack 37 moves to the outside of the lower base member 1 through the first fixed square hole 29. At this time, the center of the annular connecting member 9 is aligned with the center of the lower placement groove 4 and the upper placement groove 5 after closing, thereby locking the aligned state of the annular connecting member 9, and then pushing the locking moving block 17 to move to the first transverse groove 15 and the second transverse groove 16 at the same time, and screwing the bolt into the threaded hole aligned with the locking moving block 17, the first transverse groove 15, the second transverse groove 16 and the lower base member 1, so that the upper base member 2 and the upper moving member 3 are fixedly connected to the lower base member 1.
