Description

Technical Field

[0002] As we all know, in UHV power transmission and transformation systems, the safety and reliability of GIL equipment is the basis for the stable operation of UHV power grids. Most of the GIL equipment in use is installed with auxiliary positioning through clamps. In order to facilitate the rapid installation of the GIL equipment clamps within the limited power outage time, we propose a GIL sliding bracket with no installation and stepless adjustment.

[0003] At present, when installing sliding brackets, GIL manufacturers first adjust the position of the GIL sliding hoop based on the construction error actually measured in the tunnel. The installation position of the GIL sliding hoop needs to measure the center line of the GIL equipment based on the actual tunnel position, and then place the GIL sliding hoop on the GIL center line and the foot pad of the sliding bracket. To ensure that the GIL hoop is installed on the GIL center line, one method is to punch the hoop installation hole on the sliding bracket according to the GIL center line on site. Another method is to pre-punch the hoop installation hole on the sliding bracket, and cut the sliding bracket according to the GIL center line on site or add a pad to ensure that the GIL center is consistent with the center line of the hoop installation hole.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: See Figure 1-Figure 14A GIL sliding bracket with stepless adjustment without installation includes a GIL sliding hoop and a suspension structure.

The overall installation process is relatively simple, and the adjustment operation is relatively time-saving, which can greatly shorten the installation period of the GIL clamp. A traction rope 33 is fixedly connected to the sliding frame 29, and a hanging rope column 34 is fixedly connected to the fixed frame 30. A plurality of rope threading holes 35 are opened on the hanging rope column 34. The traction rope 33 passes through the plurality of rope threading holes 35 in sequence. The hanging rope column 34 is threaded with a plurality of threaded caps 36, and a plurality of The threaded caps 36 are used for fixing and pressing the traction ropes 33 relative to the plurality of rope threading holes 35, respectively, to improve the relative connection effect of the sliding frame 29 relative to the fixed frame 30. Once the relative threading effect between the threaded barrel 31 and the threaded rod 32 fails, it can assist in achieving the relative height limitation of the sliding frame 29 relative to the fixed frame 30. The GIL sliding hoop includes a fixed half hoop 6 and a movable half hoop 7. The fixed half hoop 6 is detachably mounted with a sliding connection 8. An articulated ear 37 is connected to the fixed half hoop 6. An articulated seat 38 and a track seat 39 are fixedly connected to the sliding connection 8. The articulated ear 37 is connected to the articulated seat 38 by a pin connecting rod. The specific pin connection structure between the fixed half hoop 6 and the sliding connection 8 is described. A groove track 40 matching the track seat 39 is provided on the fixed half hoop 6, so that the fixed half hoop 6 can be adjusted relative to the GIL being clamped. The sliding connection 8 is slidably connected in the top sliding hook cavity 4. A groove group 41 is provided at the bottom end of the sliding connection 8.

Through the design of the GIL sliding clamp, a surrounding connection structure is formed relative to the GIL, which can be selected according to the specific size of the GIL, has good versatility, and adopts a split design with the suspension structure. The installation process between the two is relatively simple and more practical.

[0023] It should be further explained that the movable half hoop 7 and the fixed half hoop 6 are respectively fixedly connected to two mounting top tubes 10 and one mounting bottom tube 11, and the mounting bottom tube 11 and the two mounting top tubes 10 can be detachably installed with auxiliary adjustment sensor assemblies, and the three auxiliary adjustment sensor assemblies all include mounting tubes 15, and the three mounting tubes 15 are all fixedly connected with end cover plates 16, and pressure sensors 17 are installed on the three end cover plates 16. The three pressure sensors 17 are respectively located in the three mounting tubes 15, and the three mounting tubes 15 are slidably connected with sliding touch rods 18. The top ends of the three sliding touch rods 18 are fixedly connected with elastic springs 19, and the three elastic springs 19 are respectively matched with the detection pressure surfaces of the three pressure sensors 17, and the three mounting tubes 15 are installed with magnetic fixed springs. The three magnetic positioning components are used for inserting and positioning the three mounting cylinders 15 relative to the mounting bottom cylinder 11 and the two mounting top cylinders 10, respectively. The three magnetic positioning components all include a rotating cylinder 20, and the three rotating cylinders 20 are all fixedly connected with permanent magnets 21, and the three permanent magnets 21 are eccentrically arranged in the three rotating cylinders 20, respectively. The mounting bottom cylinder 11 and the two mounting top cylinders 10 are all fixedly connected with face rings 22, and the face rings 22 are made of a material that can be attracted by magnetism. The three sliding touch rods 18 are all provided with middle holes 23, and the three middle holes 23 provide installation space for the three rotating cylinders 20, respectively. Through the matching of the auxiliary adjustment sensor component, the concentric detection of the GIL sliding clamp relative to the GIL clamping state can be realized, so as to facilitate the sliding clamping of the GIL. The clamping support posture of the hoop relative to the GIL is adjusted, thereby improving the support accuracy of the GIL sliding clamp relative to the GIL, and the installation and removal operations of the auxiliary adjustment sensor assembly relative to the installation top cylinder 10 and the installation bottom cylinder 11 are also relatively simple, which is convenient for the reuse of the auxiliary adjustment sensor assembly. An auxiliary rotating block 24 is fixedly connected to the rotating cylinder 20, and the auxiliary rotating block 24 is located outside the installation cylinder 15. A wing rod 25 is fixedly connected to the auxiliary rotating block 24 to facilitate the rotation force of the rotating cylinder 20. A nylon plate 12 is fixedly connected to the slider 2 through an inner hexagon countersunk screw. The nylon plate 12 is used to reduce the friction during the sliding of the sliding connection 8 in the top sliding hook cavity 4. A locking copper block 13 is slidably connected to the slider 2. The slider 2 is threadedly connected with multiple outer hexagon bolts 14 and Multiple transverse external bolts, the external hexagonal bolts 14 cooperate with the locking copper block 13 to lock the slider 2 at any position on the suspension bracket 3, the transverse external bolts are used to lock the sliding connection 8 in the slider 2, the fixed semi-hoop 6 and the movable semi-hoop 7 are provided with inner ring pads 26, and the matching GIL forms a support surface to improve the contact effect with the GIL, and the two inner ring pads 26 are respectively provided with a bottom hole 27 and two top holes 28, which are used for the passage of three sliding contact rods 18 respectively. The right end of the suspension bracket 3 is connected to the limiting end frame 44 by a spiral insertion bolt 43 to realize the sliding limit of the slider 2 relative to the suspension bracket 3, so as to prevent the slider 2 from sliding out of the suspension bracket 3 and causing the relative support between the two to fail.

[0024] The pressure sensor 17 in this embodiment is a conventional device purchased on the market and known to those skilled in the art. In the present invention, we only use it without improving its structure and function. For those skilled in the art, its setting method, installation method and electrical connection method can be debugged and operated according to the requirements of its instruction manual, and will not be described in detail here.

[0025] In summary, the working principle of the installation-free stepless adjustable GIL sliding bracket is that, when in use, the installation-free stepless adjustable GIL sliding bracket is first placed at the desired location, and the installation-free stepless adjustable GIL sliding bracket is controlled to be in the position as shown in the attached figure. Figure 1 The state shown is then adjusted, and the multiple hexagonal bolts 14 and the multiple transverse external bolts are all in a relaxed state. In this state, relative sliding can be formed between the slider 2 and the suspension bracket 3, and relative sliding can be formed between the slider 2 and the sliding connection 8. The threaded cap 36 is rotated relative to the rope column 34 to invalidate the compression and positioning effect of the threaded cap 36 on the traction rope 33, and the traction rope 33 is pulled out of the rope threading hole 35. Then, the perforated mounting seat 1 is pre-fixed and installed according to the bracket location matched with the GIL. During the fixed installation of the perforated mounting seat 1, the relative height of the sliding frame 29 and the fixed frame 30 is adjusted by rotating the adjustment threaded rod 32, and then the height of the suspension bracket 3 is adjusted, and finally the height of the GIL sliding clamp is adjusted. During this adjustment process, the sliding connection 8 moves relative to the slider 2 and the slider 2 moves relative to the The fixed half hoop 6 in the GIL sliding hoop is adapted to the bracket position of the GIL by the movement of the suspension bracket 3, so as to facilitate the placement of the GIL in the concave ring surface of the fixed half hoop 6. Then, the movable half hoop 7 is fixedly installed relative to the fixed half hoop 6 by assembling bolts 9 to form a ring-shaped clamp for the GIL sliding hoop relative to the GIL. Then, the relative height of the sliding frame 29 relative to the fixed frame 30, the relative position of the slider 2 and the suspension bracket 3, and the relative position of the sliding frame relative to the slider 2 are further adjusted according to the readings of the three pressure sensors 17, so that the readings of the three pressure sensors 17 are close. Then, by rotating a plurality of external hexagonal bolts 14 and a plurality of transverse external bolts respectively, a relative clamping positioning can be formed between the slider 2 and the suspension bracket 3, and a relative clamping positioning is also formed between the slider 2 and the sliding connection 8. Finally, the traction rope 33 is first attached to Figure 2The form shown passes through multiple rope threading holes 35 in sequence, and by spirally rotating the threaded cap 36 to the right relative to the rope hanging column 34, the multiple threaded caps 36 are respectively matched with different positions of the traction rope 33 to form compression, so as to form an auxiliary height limit of the sliding frame 29 relative to the fixed frame 30, and when the multiple threaded caps 36 form a limit operation relative to the traction rope 33, it should be implemented in sequence from right to left, that is, the rightmost threaded cap 36 first forms compression relative to the traction rope 33, and then the traction rope 33 on the left side of the rightmost threaded cap 36 is tightened, and then the compression spiral rotation of the next threaded cap 36 is performed, so that the traction rope 33 between the two adjacent threaded caps 36 is in a taut state.

[0026] Further, after the construction of the GIL bracket of the non-installation stepless adjustment is completed relative to the GIL bracket of the corresponding bracket, the three installation cylinders 15 are removed respectively relative to one installation bottom cylinder 11 and two installation top cylinders 10. During the removal process, the auxiliary rotating block 24 is first rotated with the assistance of the wing rod 25, and the auxiliary rotating block 24 rotates to drive the rotating cylinder 20 to rotate, and the rotating cylinder 20 rotates to drive the permanent magnet 21 therein. Since the permanent magnet 21 is eccentrically arranged in the rotating cylinder 20, and the relative magnetic attraction between the permanent magnet 21 and the face ring 22 is the strongest when it is as shown in the attached figure. Fig.12 In the state shown, the relative distance between the permanent magnet 21 and the face ring 22 is the shortest. Therefore, by controlling the rotating cylinder 20 to rotate one hundred and eighty degrees, the permanent magnet 21 can be controlled to enter a farther position relative to the face ring 22. Keeping the permanent magnet 21 at a farther position relative to the face ring 22 can reduce the relative magnetic attraction between the permanent magnet 21 and the face ring 22, thereby facilitating the relative separation operation of the mounting cylinder 15 relative to the mounting bottom cylinder 11 or the mounting top cylinder 10. The removed auxiliary adjustment sensor assembly can be used in conjunction with the assembly adjustment of the next GIL sliding clamp. In order to facilitate the reading of the pressure sensor 17 in the auxiliary adjustment sensor assembly, a single pressure sensor 17 can be installed on the end cover plate 16 with a liquid crystal display, or it can be connected to an external handheld reading terminal for use. The external handheld reading terminal and the pressure sensor 17 can use wired or wireless data transmission methods to achieve data transmission.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
