Description

Technical Field

[0001] The invention relates to the field of power transmission engineering, and more specifically to a pipe mother deflection adjusting hardware. Background Art

[0002] Substation is an important part of power transmission project. The main busbar in power transmission project is generally arranged in suspended tube mother, that is, the two ends of the tube mother are suspended by tube mother suspension string and suspension hardware. Due to the long length of the suspended tube mother, the rigidity performance and self-weight of the tube mother will cause obvious disturbance in the middle after the tube mother is installed.

[0003] In order to solve the problem of tube mother deflection, the prior art (Chinese invention patent with announcement number CN114759510A) discloses a tube mother deflection adjustment hardware, which mainly relies on the extension or shortening of the telescopic connector to generate a tensile pressure, so that the end of the tube mother generates a reverse bending force with the first fixed part as the support point, thereby freely adjusting the tube mother deflection;

[0004] Although the deflection of the tube busbar can be adjusted by applying force to the end of the tube busbar, applying external force directly on the tube busbar to adjust the deflection may cause uneven stress distribution inside the tube busbar. Since the tube busbar needs to carry current and change with thermal expansion and contraction for a long time, the additional pressure may cause permanent deformation, and even lead to fatigue damage or structural embrittlement, thus affecting its service life.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 A pipe mother deflection adjustment hardware, comprising a plurality of adjustment parts 2 sleeved on the outside of the pipe mother 1, the adjustment part 2 comprising a support hardware 1 23 sleeved on the outside of the pipe mother 1, two support hardware 26 symmetrically sleeved on the outside of the pipe mother 1, a connecting frame 21 fixedly connected to the upper end of the support hardware 1 23, a movable seat 22 slidably connected to the inner wall of the connecting frame 21, a screw 1 24 screwed inside the connecting frame 21, and two connecting members 25 symmetrically rotatably connected to both sides of the movable seat 22, and the other ends of the two connecting members 25 are respectively rotatably connected to the two support hardware 26, and one end of the screw 1 24 is rotatably connected to the upper end of the movable seat 22;

[0035] The two supporting hardware 26 are used to move outside the pipe mother 1 following the lifting of the movable seat 22 through the two connecting pieces 25 to achieve deflection and load adjustment.

[0036] The connecting member 25 includes a connecting portion 251 rotatably connected to the movable seat 22 at one end, a movable groove 252 opened inside the connecting portion 251, a screw rod 253 rotatably connected inside the movable groove 252, and a connecting portion 254 with one end screwed to the outside of the screw rod 253 and slidably connected to the movable groove 252. The other end of the connecting portion 254 is rotatably connected to the upper end of the adjacent supporting hardware 26.

[0037] Both sides of the connecting frame 21 are connected with suspension fittings 3 .

[0038] By adopting the above technical solution, the suspension fitting 3 is connected to the suspension system, and the connecting frame 21, the supporting fitting 1 23 and the tube mother 1 located inside the supporting fitting 1 23 are suspended by the suspension system. Since the two supporting fittings 26 are connected to the connecting frame 21 through the connecting piece 25, the two supporting fittings 26 can also support the tube mother 1. The three-point support suspension structure composed of the supporting fitting 1 23 and the two supporting fittings 26 can provide additional stability, so that the tube mother 1 can better resist bending and lateral displacement when the temperature changes, and reduce the influence of instability on the electrical performance. By rotating the screw 1 24, the movable seat 22 can move up and down inside the connecting frame 21. When the movable seat 22 descends, the movable seat 22 can be moved by The two connecting pieces 25 push the two supporting hardware pieces 26 to move laterally, thereby adjusting the distance between the two supporting hardware pieces 26 and the supporting hardware piece 1 23. By increasing the distance between the supporting points, the load borne by the tube mother 1 can be effectively dispersed, the deflection of the tube mother 1 can be controlled, the local stress of each supporting hardware piece can be reduced, the occurrence of stress concentration can be reduced, and the risk of material fatigue and damage can be reduced. By rotating the screw rod 253, one end of the connecting part 254 can be moved in the movable groove 1 252, thereby adjusting the length of the entire connecting piece 25. When the position of the supporting hardware piece 26 and the height of the movable seat 22 remain unchanged, shortening the length of the connecting piece 25 can achieve the application of force to the tube mother 1 and change the deflection of the tube mother 1.

[0039] like Figure 5 - Figure 7 As shown, it also includes a mid-line flexible adjustment portion 6 that is sleeved on the outside of the tube mother 1 and located between two adjacent adjustment portions 2. The mid-line flexible adjustment portion 6 includes a supporting hardware three 61 that is sleeved on the outside of the tube mother 1 and two rotating blocks 62 that are symmetrically connected to the upper end of the supporting hardware three 61. The upper end of the connecting frame 21 is symmetrically connected to two traction units 4, and the traction unit 4 is connected to the rotating block 62 through a traction line 7.

[0040] The traction unit 4 includes a shell 41 fixedly connected to the upper end of the connecting frame 21, a slide 45 slidably connected to the inside of the shell 41, a hydraulic rod 42 fixedly connected to the upper end of the shell 41, a tooth key 46 opened on one side of the slide 45, two gears 47 symmetrically connected to the inside of the shell 41 and meshing with the tooth key 46, and a winding roller 48 located between the two gears 47 and fixedly connected to the two gears 47 at both ends. The telescopic end of the hydraulic rod 42 penetrates into the shell 41 and is fixedly connected to the upper end of the slide 45.

[0041] The housing 41 is also integrally formed with two extension ends 43 on one side, and a guide roller 44 is rotatably connected between the two extension ends 43 .

[0042] The outer surface of the second connecting part 254 is fixedly connected with an elastic positioning component 5, and the elastic positioning component 5 includes a concave frame 51 fixedly connected to the outer surface of the second connecting part 254, two slide grooves 52 symmetrically arranged inside the concave frame 51, two guide rods 53 fixedly connected to the two slide grooves 52, two slide seats 55 respectively slidably connected in the two slide grooves 52 and movably sleeved on the outside of the guide rod 53, a guide roller 56 rotatably connected between the two slide seats 55, two springs 54 respectively sleeved on the outside of the two guide rods 53, and a sensor 57 fixedly connected to the inside of the concave frame 51, and the two ends of the spring 54 are respectively connected to the inner wall of the slide groove 52 and one side of the slide seat 55.

[0043] Two extension portions 58 are symmetrically fixed to the outer surface of the concave frame 51 on both sides, and guide grooves 59 are formed inside the two extension portions 58 .

[0044] By adopting the above technical solution, since the two ends of the tube mother 1 are supported by the two adjustment parts 2, the deflection of the middle part of the tube mother 1 will change when it is affected by temperature. Therefore, by installing a support hardware three 61 in the middle part of the tube mother 1, and connecting the support hardware three 61 to the traction unit 4 through the traction line 7, the traction support of the middle part of the tube mother 1 is realized. Since one end of the traction line 7 extends from the winding roller 48, the traction line 7 is connected to the rotating block 62 after being guided by the guide roller 1 44 and the guide roller 2 56, when the tube mother When the deflection of the middle part of the pipe 1 changes, the position of the support fitting 3 61 may change. When the support fitting 3 61 moves downward with the change of the deflection of the pipe mother 1, one end of the traction line 1 7 moves with the support fitting 3 61. At the same time, the traction line 1 7 will press the guide roller 2 56, and the slide 2 55 will slide downward in the slide groove 52. The spring 1 54 will contract. When the slide 2 55 moves to the position of the sensor 57, the sensor 57 generates a signal and sends it to the hydraulic rod 42 (because the pipe mother 1 is used to transmit current, there may be a high voltage environment around it. In order to To avoid affecting the operation of the hydraulic rod 42, in the present application, the hydraulic rod 42 is wrapped with insulating and shielding materials, and the shell 41 is also made of insulating materials. At the same time, the hydraulic rod 42 is also grounded to prevent static electricity accumulation and leakage, thereby reducing its operating risk. Insulation isolation and anti-shielding are also commonly used treatment methods in the field of power transmission, which will not be repeated here. The hydraulic rod 42 contracts during operation and drives the slide 45 to move upward. When the slide 45 moves, the gear 47 and the winding roller 48 are driven to rotate through the tooth key 46. The rotation of the winding roller 48 can The lead wire 7 is taken up and the winding roller 48 rotates to tighten the traction wire 7. When the deflection of the middle part of the mother tube 1 changes, the traction force applied by the traction wire 7 to the supporting hardware 3 61 can effectively offset a part of the downward bending moment, enhance the bending resistance of the middle part, reduce bending deformation, and adjust the force of the middle hardware in real time, so as to effectively control the deflection of the mother tube 1, reduce the residual strain caused by thermal expansion and contraction, reduce the risk of material fatigue and long-term deformation, make the whole structure more stable, and improve the overall reliability.

[0045] like Figure 1 , Figure 4 , Figure 5 As shown, the wire bending adjustment part 6 also includes two plates 63 symmetrically connected to the lower end of the supporting hardware 3 61, two rollers 64 respectively connected to the upper ends of the two plates 63, two seats 65 respectively connected to one side of the two plates 63, two rollers 66 respectively connected to the upper ends of the two seats 65, and traction holes 67 opened in the two seats 65. A traction wire 2 8 is also wound around the outside of the winding roller 48, and one end of the traction wire 2 8 passes through the guide groove 59 and is tied to the traction hole 67.

[0046] By adopting the above technical solution, when the winding roller 48 rotates to reel in the traction line 7, it can also pull the traction line 2 8. The traction line 2 8 can drive the free ends of the seat body 65 and the plate body 63 to rotate toward the lower surface of the tube mother 1, so that the roller body 1 64 can contact the lower surface of the outer wall of the tube mother 1, providing additional support for the middle part of the tube mother 1, and can better disperse and bear the load of the middle part of the tube mother 1, improve the stability of the overall structure, and can significantly improve the bending strength of the middle part of the tube mother 1, reduce its deformation under the action of external force, so that it can maintain a more stable state during operation.

[0047] like Figure 8 and Fig. 9 As shown, the two plate bodies 63 are each provided with a movable groove 2 631 inside, and the two movable grooves 231 are respectively movably connected with two extension seats 651, one end of the two extension seats 651 is respectively fixedly connected to one side of the two seat bodies 65, the inner walls of the two movable grooves 231 are also fixedly connected with a guide rod 2 68, and the two extension seats 651 are movably sleeved on the outside of the guide rod 2 68, and the outside of the guide rod 2 68 is also sleeved with a spring 2 69, and the two ends of the spring 2 69 are respectively connected to the inner wall of the movable groove 2 631 and one side of the extension seat 651.

[0048] By adopting the above technical solution, when the traction line 2 8 pulls the seat body 65 and one end of the plate body 63 to rotate, it can also apply a pulling force to the extension seat 651, and pull the extension seat 651 out of the movable groove 2 631, so that the length of the plate body 63 is extended, and the roller body 2 66 on the extension seat 651 can move along the lower surface of the tube mother 1, so that the distance between the roller body 1 64 and the roller body 2 66 becomes larger, and the lower surface of the tube mother 1 is dispersedly supported, so as to better disperse the load applied to the tube mother 1, improve the overall support capacity, effectively optimize the stress distribution, reduce the local stress concentration phenomenon, reduce the risk of material fatigue and potential damage, increase the support and bending resistance, and can reduce the fatigue risk of the tube mother 1 in long-term operation and improve its service life.

[0049] Method of use: The suspension fitting 3 is connected to the suspension system, and the connecting frame 21, the supporting fitting 23 and the tube mother 1 located inside the supporting fitting 23 are suspended by the suspension system. The movable seat 22 can be moved up and down inside the connecting frame 21 by rotating the screw rod 24. When the movable seat 22 descends, the movable seat 22 can push the two supporting fittings 26 to move horizontally through the two connecting pieces 25, so as to adjust the distance between the two supporting fittings 26 and the supporting fitting 23. By increasing the distance between the supporting points, the load borne by the tube mother 1 can be effectively dispersed. When the deflection of the middle part of the tube mother 1 changes, the position of the supporting fitting 3 61 may change. When the supporting fitting 3 61 moves downward with the change of the deflection of the tube mother 1, one end of the traction line 7 moves with the supporting fitting 3 61. At the same time, the traction line 7 will press the guide roller 2 56, and the slide seat 2 55 will move in the slide groove. 52 slides downward, spring 1 54 contracts, and when slide seat 2 55 moves to the position of sensor 57, sensor 57 generates a signal and sends it to hydraulic rod 42, hydraulic rod 42 works and contracts and drives slide seat 1 45 to move upward, and when slide seat 1 45 moves, gear 47 and winding roller 48 are driven to rotate through tooth key 46, and winding roller 48 rotates to wind up traction line 1 7, and winding roller 48 rotates to tighten traction line 1 7, and the traction force applied to supporting hardware 3 61 by traction line 1 7 can effectively offset a part of the downward bending moment and enhance the bending resistance of the middle part, and when winding roller 48 rotates to wind up traction line 1 7, it can also pull traction line 2 8, and traction line 2 8 can drive the free ends of seat body 65 and plate body 63 to rotate toward the lower surface of pipe mother 1, so that roller body 1 64 can contact with the lower surface of the outer wall of pipe mother 1, providing additional support for the middle part of pipe mother 1.

[0050] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
