[0002] In power plants and substations, the conductors that connect engines, transformers and various electrical appliances in the power distribution equipment at all voltage levels are called busbars. Busbars are classified into rigid busbars and flexible busbars according to their structure.

[0003] During the installation of flexible busbars, multiple brackets are typically installed first at the required locations. The busbar is then placed on these brackets. Under its own weight, the busbar between two brackets will exhibit a slight sag, forming a sag. Sag refers to the vertical distance from the lowest point of the overhead conductor to the line connecting the two suspension points of the conductor. Conductor sag has a significant impact on the safe operation of the line. After conductor installation, inconsistencies in sag between adjacent brackets can easily occur, increasing the risk to the safe operation of the line later on. Summary of the Invention

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses an installation device for adjusting the sag of a conductor. (Refer to...) Figure 1 and Figure 2 The installation device for adjusting the sag of the conductor includes multiple brackets 1 and guide cables 2 set on the brackets 1. In this embodiment, the brackets 1 are scaffolding built of multiple steel pipes. In other embodiments, the brackets 1 can also be columns. The multiple brackets 1 are arranged in a straight line. The two ends of the guide cables 2 are respectively tied to the brackets 1 at both ends. The length direction of the guide cables 2 is parallel to the arrangement direction of the multiple brackets 1, so that the guide cables 2 span two adjacent brackets 1. The guide cables 2 are in a taut state and are located above the conductor on the brackets 1.

[0023] Reference Figure 1 and Figure 2 Multiple mounting blocks 3 are sleeved on the guide steel cable 2 between adjacent brackets 1. An odd number of mounting blocks 3 are provided between adjacent brackets 1. In this embodiment, five mounting blocks 3 are provided between adjacent brackets 1. In other embodiments, the number of mounting blocks 3 between adjacent brackets 1 can be set according to the spacing between adjacent brackets 1. Connecting ropes 4 are movably arranged on opposite sides of the mounting blocks 3. The connecting ropes 4 are made of steel wire rope. A fixing member 5 for fixing relative to the conductor is provided between two opposite connecting ropes 4. An adjustment component 6 for synchronously winding or unwinding the connecting ropes 4 on both sides is provided on the mounting blocks 3.

[0024] During construction, multiple brackets 1 are installed in the required positions, and then the conductors are installed on the multiple brackets 1. Then, guide steel cables 2 are tied between the brackets 1 at both ends. The guide steel cables 2 are in a taut state. The connecting ropes 4 are fixedly connected to the corresponding positions of the conductors by the fixing parts 5 on the connecting ropes 4. Then, the connecting ropes 4 on both sides are simultaneously wound up by the adjusting component 6 to tighten the connecting ropes 4, which helps to reduce the sag as needed. At the same time, the connecting ropes 4 on both sides are simultaneously unwound by the adjusting component 6. Under the weight of the conductors, the sag is widened as needed. This allows the sag between adjacent brackets 1 to be adjusted as needed, making it easier to adjust the sag between adjacent brackets 1 to be consistent, which helps to ensure the safe operation of the line in the later stage.

[0025] Reference Figure 2 and Figure 3 To facilitate the fixing of the connecting rope 4 to the conductor, the fixing component 5 includes a fixing support 51 and a fixing rope 52. The fixing support 51 is located below the conductor and is made of a wooden board. The fixing rope 52 is wrapped around the conductor and connected to the fixing support 51. Specifically, the fixing rope 52 is wrapped around the conductor and tied to both sides of the fixing support 51, thereby fixing the fixing support 51 and the conductor relatively. The fixing rope 52 can be made of steel wire or iron wire, etc. The connecting rope 4 is connected to the fixing rope 52. Specifically, the connecting ropes 4 on both sides are tied to the side of the fixing rope 52 located above the conductor.

[0026] When it is necessary to adjust the sag of the conductor, a fixed support 51 is placed below the desired position of the conductor. Then, the conductor is wound with a fixed rope 52, and the two ends of the fixed rope 52 are tied to the two ends of the fixed support 51 respectively, thereby fixing the conductor, the fixed support 51 and the fixed rope 52 relatively. Then, the connecting ropes 4 on both sides are tied to the opposite sides of the fixed rope 52 respectively, so that the sag of the conductor can be adjusted when the connecting ropes 4 are wound or unwound. The fixed support 51 can reduce the stress on the conductor and prevent the conductor from being damaged.

[0027] Reference Figure 2 A padding layer 15 is placed between the fixing rope 52 and the conductor. The padding layer 15 can be made of cloth, rubber, etc. The padding layer 15 reduces the friction and stress of the fixing rope 52 on the conductor, which helps to protect the conductor.

[0028] Reference Figure 2 and Figure 3To facilitate the winding or unwinding of the connecting rope 4, an installation cavity 16 is provided in the mounting block 3. The adjusting component 6 includes a drum 61 and a rotating component 62. The drum 61 is rotatably disposed in the installation cavity 16. The drum 61 corresponds one-to-one with the connecting rope 4. The rotation axis of the drum 61 is parallel to the length direction of the guide steel cable 2. The arrangement direction of the two drums 61 is perpendicular to the length direction of the guide steel cable 2. Notches 17 are provided on both sides of the mounting block 3. The notches 17 are connected to the installation cavity 16. The end of the connecting rope 4 away from the fixed rope 52 moves through the notch 17 and is wound around the corresponding drum 61. The rotating component 62 is disposed on the mounting block 3 and is used to drive the two drums 61 to rotate synchronously.

[0029] Reference Figure 2 and Figure 3 To facilitate the synchronous rotation of the two drums 61, a connecting shaft 18 is coaxially connected to each drum 61. The connecting shaft 18 rotates within the mounting cavity 16. The rotating component 62 includes a first gear 621, a second gear 622, and a micro motor 623. The first gear 621 is rotatably disposed within the mounting cavity 16, located between the two drums 61. The rotation axis of the first gear 621 is parallel to the rotation axis of the drums 61. The second gear 622 is coaxially sleeved on the connecting shaft 18 of the drums 61, so that the first gear 621 is located between the second gears 622 on the two drums 61. The first gear 621 meshes with the second gears 622 on both sides. The connecting rope 4 is wound in opposite directions on the corresponding drums 61, so that the connecting rope 4 can be wound or unwound simultaneously when the two drums 61 rotate in opposite directions. The micro motor 623 is fixedly mounted on the outer wall of the mounting block 3, and the first gear 621 is coaxially fixed with the output shaft of the micro motor 623.

[0030] When it is necessary to tighten or loosen the connecting rope 4, the micro motor 623 is started. The micro motor 623 drives the first gear 621 to rotate. The first gear 621 drives the second gears 622 on both sides to rotate. The second gears 622 drive the corresponding drums 61 to rotate through the connecting shaft 18, so that the drums 61 on both sides rotate in opposite directions. The two drums 61 simultaneously wind up or unwind the connecting rope 4, thereby facilitating the adjustment of the sag of the wire.

[0031] Reference Figure 1 and Figure 2 A counterweight 19 is fixed on the side of the mounting block 3 away from the micro motor 623. The counterweight 19 helps to maintain the stability of the mounting block 3 on the guide cable 2.

[0032] Reference Figure 1 and Figure 3A rangefinder 7 is installed on the bottom wall of the mounting block 3 located in the middle between adjacent brackets 1. This rangefinder 7 measures the distance from the mounting block 3 to the conductor. The rangefinder 7 is wirelessly connected to an external terminal platform. Since the mounting block 3 located in the middle between adjacent brackets 1 is usually aligned with the lowest point of the conductor, the distance from the rangefinder 7 to the lowest point of the conductor is measured by the rangefinder 7. Then, the vertical distance from the rangefinder 7 to the point where the conductor contacts the bracket 1 is subtracted. This helps the operator determine the sag of the conductor between adjacent brackets 1, and thus facilitates the adjustment of the sag between adjacent brackets 1 to be consistent as needed.

[0033] Reference Figure 2 and Figure 3 A hanging block 10 is fixed in the middle of the top wall of the mounting block 3. The top wall of the hanging block 10 is an arc surface that bulges outward away from the mounting block 3. The hanging block 10 has an insertion channel 11 for the guide cable 2 to be moved in. The insertion channel 11 is opened in the horizontal direction. The hanging block 10 has a hanging channel 12, which is opened in the vertical direction. The hanging channel 12 is located in the middle of the mounting block 3, above the insertion channel 11 and connected to one end of the insertion channel 11.

[0034] Reference Figure 2 and Figure 3 The bottom wall of the insertion channel 11 has a groove 20, which is aligned with the hanging channel 12. A contact block 13 is slidably disposed in the groove 20. The sliding direction of the contact block 13 is parallel to the length direction of the hanging channel 12. The side of the contact block 13 near the hanging channel 12 is an arc surface, which is concave inward toward the groove 20 to accommodate the guide cable 2. The contact block 13 is aligned with the hanging channel 12. A rodless cylinder 14 is installed on the side wall of the hanging channel 12. The rodless cylinder 14 extends into the groove 20. The contact block 13 is fixedly connected to the movable part of the rodless cylinder 14.

[0035] When it is necessary to attach the hook block 10 to the guide cable 2, the rodless cylinder 14 is activated to drive the abutment block 13 downward, so that the abutment block 13 moves into the groove 20. Then, the guide cable 2 is aligned with the insertion channel 11, and the guide cable 2 enters the hooking channel 12 along the insertion channel 11 until the guide cable 2 reaches the top of the hooking channel 12. Then, the rodless cylinder 14 is activated, and the rodless cylinder 14 drives the abutment block 13 upward, so that the concave arc surface of the abutment block 13 abuts against the guide cable 2. This fixes the mounting block 3 relative to the guide cable 2, preventing unnecessary sliding of the mounting block 3 on the guide cable 2. When the position of the mounting block 3 needs to be adjusted, the rodless cylinder 14 is activated to drive the abutment block 13 downward, causing the abutment block 13 to disengage from the guide cable 2. At this time, the mounting block 3 can be slid along the guide cable 2 to adjust its position. When it is necessary to completely remove the hook block 10 from the guide cable 2, the mounting block 3 is moved so that the guide cable 2 can be moved out from the insertion channel 11.

[0036] Reference Figure 4 Support rods 21 are fixed on opposite sides of the top of bracket 1. The length direction of the support rods 21 is perpendicular to the length direction of the guide cable 2. The arrangement direction of the two support rods 21 is parallel to the length direction of the guide cable 2. The guide cable 2 overlaps above the two support rods 21, so that the support rods 21 support the guide cable 2, which helps to enhance the stability of the guide cable 2.

[0037] Reference Figure 4 The bracket 1 has two guide groups 22 arranged opposite each other, with the arrangement direction of the two guide groups 22 parallel to the length direction of the guide cable 2. Each guide group 22 includes two guide rods 221 arranged opposite each other on the bracket 1, with the two guide rods 221 spaced apart in the vertical direction. The length direction of the guide rods 221 is perpendicular to the length direction of the guide cable 2. The wire passes sequentially between the two guide rods 221 of the guide group 22. This helps to guide and limit the wire, making it less likely for the wire to detach from the bracket 1.

[0038] Reference Figure 4 An adjusting roller 8 is slidably mounted on the bracket 1. The adjusting roller 8 is located above the guide wire and between two sets of guide groups 22. The adjusting roller 8 is slidably mounted vertically and is located in the middle of the bracket 1. The length direction of the adjusting roller 8 is perpendicular to the length direction of the guide cable 2. The bracket 1 is provided with a sliding component for driving the adjusting roller 8 to slide. The sliding component includes two electric push rods 9 mounted on the bracket 1. The two electric push rods 9 are located at both ends of the length direction of the adjusting roller 8. The extension direction of the electric push rods 9 is parallel to the sliding direction of the adjusting roller 8. The end of the adjusting roller 8 is fixedly connected to the piston rod of the corresponding electric push rod 9. In other embodiments, the electric push rod 9 can be replaced by a cylinder, electric cylinder, etc.

[0039] When the sag detected by the rangefinder 7 is too long, the wire is pulled up by the connecting rope 4 to make the wire relatively loose. At this time, the electric push rod 9 is activated, and the electric push rod 9 pulls the adjusting roller 8 down, so that the adjusting roller 8 presses the wire down, thereby adjusting and fixing the wire so that the sag of the wire is not easily changed after the connecting rope 4 is removed. When the sag is too short, the electric push rod 9 is activated, and the electric push rod 9 pushes the adjusting roller 8 up, reducing the folded part of the wire and helping to adjust the sag of the wire.

[0040] The implementation principle of this application embodiment is as follows: During construction, multiple brackets 1 are installed and fixed in the required position. Then, the wire is installed on multiple brackets 1, so that the wire passes through the two guide rods 221 of the guide group 22 on the bracket 1 in sequence. At this time, the adjusting roller 8 is located above the wire and is detached from the wire. Then, the guide steel cable 2 is tied between the brackets 1 at both ends. The guide steel cable 2 is in a taut state and overlaps the support rod 21. Then, a fixed support 51 is placed below the required position of the wire. The wire is wrapped with a fixed rope 52, and the two ends of the fixed rope 52 are tied to the two ends of the fixed support 51 respectively, so that the wire, the fixed support 51 and the fixed rope 52 are relatively fixed.

[0041] Next, the rodless cylinder 14 is activated to drive the abutment block 13 downward into the groove 20. Then, the guide cable 2 is aligned with the insertion channel 11 and enters the hanging channel 12 along the insertion channel 11 until the guide cable 2 reaches the top of the hanging channel 12. Then, the rodless cylinder 14 is activated to drive the abutment block 13 upward, so that the concave arc surface of the abutment block 13 abuts against the guide cable 2. Then, the connecting ropes 4 on both sides are tied to the opposite sides of the fixing rope 52, and the micro motor 62 is activated. 3. The micro motor 623 drives the first gear 621 to rotate, which in turn drives the second gears 622 on both sides to rotate, causing the drums 61 on both sides to rotate in opposite directions. The two drums 61 simultaneously wind up or unwind the connecting rope 4, thereby adjusting the sag of the conductor. Based on the distance measured by the rangefinder 7, the sag between adjacent brackets 1 is adjusted to be consistent. The electric push rod 9 is activated to drive the adjusting roller 8 to move and contact the conductor, thereby fixing the conductor relatively and helping to ensure the safe operation of the line in the later stage.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
