Description

Technical Field

[0001] The present application belongs to the technical field of nuclear power plant electrical equipment installation, and specifically relates to an installation device for GIL. Background Art

[0002] Gas insulated transmission line (GIL) is an ultra-high voltage, high current power transmission equipment that uses sulfur hexafluoride (SF6) gas insulation technology and has a coaxial casing and conductor arrangement. Compared with traditional overhead lines or transmission cable technology, it has the advantages of large current carrying capacity, low failure rate, easy maintenance, high space resource utilization, and no impact from harsh climate and special terrain. It is widely used in power grids and power plants.

[0003] In a nuclear power plant, GIL is installed in a dedicated civil engineering corridor. During the installation process, it needs to be hoisted, transported and docked in sections and phases (i.e., divided into three phases). Due to the large size and high weight of the GIL cylinder, it is difficult to transport, lift and flip it. The traditional GIL installation process requires three sets of special tools, including a dedicated transfer trolley, a lifting crane and a flipping tool.

[0069] In order to make those skilled in the art better understand the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, not all. Based on the embodiments recorded in the present application, all other embodiments obtained by those skilled in the art without paying creative work are within the scope of protection of the present application.

[0070] See also Figure 1 , which is a schematic diagram of the structure of an installation device for GIL provided in an embodiment of the present application.

[0071] The installation device for GIL provided in the embodiment of the present application comprises: a lifting platform 1, a leg 2 for supporting the lifting platform 1, a lifting ring support beam 3, a lifting assembly and a lifting ring 4;

[0072] like Figure 2-Figure 5As shown, a lifting track support rod 5 is provided in the space formed by the left and right groups of legs 2; each lifting track support rod 5 is provided with a lifting track 6 vertically extending along the direction of the legs; the two lifting tracks 6 are arranged opposite to each other, as shown in FIG. Figure 6 As shown;

[0073] Both ends of the lifting ring support beam 3 are respectively arranged in two lifting rails 6, and move up and down along the lifting rails 6 under the drive of the lifting assembly; the lifting ring 4 is used to grab the GIL cylinder to be installed, and can move left and right along the lifting ring support beam 3.

[0074] It can be understood that the lifting assembly drives the lifting ring support beam 3 to rise or fall, thereby realizing the functions of lifting and adjusting the height of the GIL cylinder; the lifting ring 4 can move left and right along the lifting ring support beam 3, thereby realizing the transportation function of the GIL cylinder.

[0075] In one example, there are three lifting rings 4 to simultaneously grasp three GIL cylinders of three phases A / B / C.

[0076] In some possible implementations of the present application, such as Figure 7 and Figure 8 As shown, the lifting ring 4 specifically includes: a lifting ring bracket 41, a lifting ring support wheel 42 and two semicircular claw hooks 43;

[0077] A rack 44 is fixed to the upper end of the ring bracket 41, and a rotatable ratchet 31 meshing with the rack 44 is fixed to the ring support beam 3; the ring support wheel 42 is fixed to the ring bracket 41, and the ring bracket 41 fixes the ring support wheel 42 to the ring support beam 3;

[0078] One end of the two semicircular claw hooks 43 is fixed to the lower end of the eye bracket 41, and the other end is fixed by a buckle 45, so as to fix the GIL cylinder.

[0079] It can be understood that the ratchet 31 can be rotated forward and reversely, and the rack 44 can drive the eye bracket 41 and the eye support wheel 42 along the eye support beam 3 to move the eye 4 left and right, so that the position of the GIL cylinder to be installed is completely corresponding to the position of the installed GIL cylinder.

[0080] As an example, the device further comprises a ratchet crank 34 for rotating the ratchet 31, such as Fig. 9 As shown; the ratchet crank 34 is a Z-shaped structure, one end of which can be locked with the inner ring of the ratchet 31.

[0081] In one example, a ratchet brake handle 32 is fixed to one side of the ratchet 31, and a brake rack 33 matching the ratchet 31 is provided on the ratchet brake handle 32. Fig.10 shown.

[0082] It is understandable that when the GIL cylinder to be installed is moved to the target position, the brake rack 33 can be engaged with the ratchet 31 by moving the ratchet brake handle 32, thereby locking the ratchet 31 and thus locking the position of the lifting ring 4, thereby locking the position of the GIL cylinder to be installed.

[0083] In some possible implementations of the embodiments of the present application, a cylindrical ball 46 is provided on the semicircular claw hook 43. The cylindrical ball 46 can be used to rotate the GIL cylinder in the hanging ring 4, so that the flange of the three-phase GIL cylinder to be installed and the flange bolt holes of the installed three-phase GIL cylinder are completely corresponding.

[0084] In one example, each semicircular claw hook 43 is provided with two cylindrical balls 46 , which are respectively provided at the lower end and the side end of the semicircular claw hook 43 .

[0085] In some possible implementations of the embodiments of the present application, the ring support beam 3 may be a T-shaped structure;

[0086] The ring bracket 41 fixes the ring support wheel 42 to the horizontal steel plate of the ring support beam 3. Fig.11 shown.

[0087] In an example, Fig.12 As shown, the buckle 45 includes: a stationary clamp 451 and a rotating clamp 452;

[0088] The other ends of the two semicircular claw hooks 43 are each provided with a through hole, and the static clamp 451 and the rotating clamp 452 can pass through the through hole. The rotating clamp 452 can be rotatably connected to one end of the static clamp 451, and the other end of the static clamp 451 is fixed with a pull ring 453 larger than the through hole.

[0089] It can be understood that one end of the two semicircular claw hooks 43 is rotatably fixed to the lower end of the eye bracket 41, the buckle 45 is inserted into the through hole in a straight position, and the rotating clamp 452 of the buckle 45 is rotated counterclockwise, so that the rotating clamp 452 of the buckle 45 and the static clamp 451 form an angle of 90 degrees, and the two semicircular claw hooks 43 of the eye 4 are locked and cannot be separated, and the GIL cylinder cannot be separated from the eye 4. The rotating clamp 452 of the buckle 45 is rotated clockwise to change the rotating clamp 452 of the buckle 45 from a vertical position to a horizontal position, and the static clamp 452 and the rotating clamp 453 are in a horizontal state, then the buckle 45 becomes a straight line, and the buckle 45 can be pulled out of the through hole, and the two semicircular claw hooks 43 are separated to put the GIL cylinder into the eye 4 or to separate the eye 4 from the GIL cylinder.

[0090] In some possible implementations of the present application, such as Figure 1 As shown, the lifting assembly includes: a power output device 11, a winch shaft 12, two winch drum brackets 13 and two winch drums 14;

[0091] The power output device 11 drives the winch shaft 12 to move, and both ends of the winch shaft 12 are fixed to the upper end of the lifting platform 1 by means of a winch drum bracket 13;

[0092] Two hoisting drums 14 are fixed on the hoisting shaft 12 and connected to the eye support beam 3 via a steel wire rope 15; two steel wire rope passage holes 16 for passing the steel wire ropes are provided on the lifting platform 1.

[0093] It can be understood that the power output device 11 drives the winch shaft 12 to move, and the two winch drums 14 rotate accordingly, tightening or lowering the wire rope 15, adjusting the height of the eye support beam 3, and thus adjusting the height of the GIL cylinder, so that the height of the installed GIL cylinder and the height of the GIL cylinder to be installed can be kept completely consistent.

[0094] In some possible implementations of the present application, such as Fig.13 As shown, the power output device 11 includes: a first transmission gear 111, a second transmission gear 112, a transmission shaft 113, a transmission shaft bracket 114, a lifting motor 115 and a third transmission gear 116;

[0095] The first transmission gear 111 is fixed on the hoist shaft 12, the second transmission gear 112 is meshed with the first transmission gear 111 and fixed on the transmission shaft 113, and the transmission shaft 113 is fixed to the upper end of the lifting platform 1 through the transmission shaft bracket 114;

[0096] The third transmission gear 116 is meshed with the second transmission gear 112 , and the lifting motor 115 drives the third transmission gear 116 to rotate.

[0097] In an example, Fig.14 As shown, the power output device 11 further includes: a meshing shaft 117, a meshing gear 118, a brake gear 119, an electromagnet 120, a meshing gear bracket 121, a spring 122 and a brake gear bracket 123;

[0098] The third transmission gear 116 and the meshing gear 118 are both fixed on the meshing shaft 117. The lifting motor 115 drives the meshing shaft 117 to rotate. The meshing shaft 117 is fixed to the upper end of the lifting platform 1 through the meshing gear bracket 121.

[0099] The brake gear 119 is connected to the brake gear bracket 123 through the spring 122, and the brake gear bracket 123 is fixed to the upper end of the lifting platform 1; when the spring 122 is not deformed, the brake gear 119 is meshed with the meshing gear 118; the electromagnet 120 is used to stretch the spring 122, and the brake gear 119 is disengaged from the meshing gear 118.

[0100] It is understandable that the lifting motor 115 is started, and the lifting motor 115 and the electromagnet 122 are powered at the same time. The electromagnet 122 is powered, the brake gear 119 is attracted by the electromagnetic force 120, the spring 122 is stretched and stores energy, and the brake gear 119 is disengaged from the meshing gear 118 at the same time, and the shaft of the lifting motor 115 can rotate; the lifting motor 115 is powered and controlled to rotate in the opposite direction, and through two sets of transmission gears, the transmission shaft 113 is used to rotate in the opposite direction, driving the hoist drum 14 to rotate in the opposite direction, and the hoist drum 14 drives the wire rope 15, the lifting ring support beam 3, and the lifting ring 4 to descend. When the lifting ring 4 descends to the same level as the GIL cylinder, the lifting motor 115 is stopped. The electromagnet 120 loses power, the brake gear 119 loses electromagnetic attraction, and resets under the action of the tension of the spring 122, meshing with the meshing gear 118, the shaft of the lifting motor 115 is locked and cannot rotate, and the height of the lifting ring 4 is locked to prevent the GIL cylinder from falling.

[0101] In some possible implementations of the embodiments of the present application, the device further includes: a universal wheel 21, a driving wheel 22 and an electric walking subsystem 23;

[0102] The lower ends of the two front legs 2 are fixed with driving wheels 22, and the lower ends of the two rear legs 2 are fixed with universal wheels 21; the electric walking subsystem drives the driving wheels 22 to realize functions such as electric walking and turning, replacing manpower with electric power and improving the efficiency of GIL installation.

[0103] In an example, Fig.15 and Fig.16 As shown, the electric travel subsystem 23 includes: a travel motor 231, a first bevel gear 232, a fourth transmission gear 233, a bevel gear fixing shaft 234, a second bevel gear 235, a driving wheel shaft 236, a fifth transmission gear 237 and a driving wheel bracket 238;

[0104] The fifth transmission gear 237 is fixed to the driving wheel 22 and is fixed inside the driving wheel bracket 238 via the driving wheel shaft 236;

[0105] The fourth transmission gear 233 and the second bevel gear 235 are fixed and fixed inside the driving wheel bracket 238 through the bevel gear fixing shaft 234. The fourth transmission gear 233 is meshed with the fifth transmission gear 237, and the second bevel gear 235 is meshed with the first bevel gear 232.

[0106] The travel motor 231 drives the first bevel gear 232 to move, thereby driving the driving wheel 22 to rotate, and pushing the universal wheel 21 to rotate, and finally driving the device to move, and moving the device to the top of the GIL cylinder.

[0107] In some possible implementations of the embodiments of the present application, in order to facilitate transportation, such as Figure 5As shown, the same side of the two lifting rails 6 is provided with a support beam mounting hole 61 for installing the ring support beam 3 into the lifting rail 6. Through the support beam mounting hole 61, the ring support beam 3 can be installed into the lifting rail 6 or taken out from the lifting rail 6.

[0108] In some possible implementations of the embodiments of the present application, the lifting platform 1 and the legs 2 are connected via a leg rotation joint 24, and are connected to an obliquely supported folding rod 25 for folding the legs 2 to reduce the storage area of ​​the device.

[0109] In an example, Fig.17 and Fig.18 As shown, the folding rod 25 comprises: an upper folding rod joint 251 and a lower folding rod joint 252;

[0110] One end of the folding rod lower joint 252 is connected to the leg 2, and the other end is provided with a slideway 253;

[0111] One end of the folding rod upper joint 251 is connected to the lifting platform 1, and the other end is fixed with a slider 254 that moves along the slideway 253;

[0112] A slidable fixing sleeve 255 is sleeved on the upper joint 251 of the folding rod; a stop block 256 is fixed on the lower joint 252 of the folding rod, and the stop block 256 is used to lock the fixing sleeve 255 at the connection between the lower joint 252 of the folding rod and the upper joint 251 of the folding rod.

[0113] It can be understood that by lifting the fixing sleeves 255 of the four folding rods 25 upwards to disengage them from the connection between the lower joint 252 of the folding rod and the upper joint 251 of the folding rod, the four folding rods 25 can be changed from an extended state to a folded state, and the four legs 2 can be changed to a folded state to reduce the storage area of ​​the device.

[0114] The following describes in detail a specific method for using a GIL installation device provided in an embodiment of the present application with reference to a specific example.

[0115] In the initial state of the installation device for GIL provided in the embodiment of the present application, the legs 2 are in a folded state; the four folding rods 25 are opened (i.e., changed from a folded state to an extended state), and the folding rod fixing sleeve 255 is pulled downward and sleeved on the connection between the lower joint 252 of the folding rod and the upper joint 251 of the folding rod to fix and prevent bending; the lifting ring support beam 3 is installed into the lifting rails 6 on both sides through the support beam mounting hole 61 to complete the installation of the installation device.

[0116] When in use, the three-phase GIL cylinder to be installed is placed on three brackets in the GIL corridor, and the travel motor 231 is started. Through two bevel gears and two transmission gears, the drive wheel 22 is driven to rotate, and the universal wheel 21 is pushed to rotate, and finally the device is driven to move and move the device to the top of the three-phase GIL cylinder.

[0117] Insert the ratchet crank 34 into the hexagonal groove of the ratchet 31, and shake the ratchet crank 34 to rotate the ratchet 31. Through forward and reverse rotation, the lifting ring 4 can be moved left and right, so that the three lifting rings 4 are respectively located directly above the three-phase GIL cylinder.

[0118] Remove the buckles under the three lifting rings 4 (for example, rotate the rotating clamp 452 of the buckle 45 clockwise to change the rotating clamp 452 of the buckle 45 from the vertical position to the horizontal position, so that the buckle 45 becomes a straight line and can be pulled out from the perforation), open the two semicircular claw hooks 43 of the lifting ring 4, so that the three lifting rings 4 are in an open state;

[0119] Start the lifting motor 115, and power on the lifting motor 115 and the electromagnet 120 at the same time. The electromagnet 120 is energized, and the brake gear 119 is attracted by the electromagnetic force 120 and moves to the right. The spring 122 is stretched and stores energy. At the same time, the brake gear 119 is disengaged from the meshing gear 118, and the shaft of the lifting motor 115 can rotate; the lifting motor 11 is energized and controlled to rotate in the opposite direction. Through two sets of transmission gears, the transmission shaft 113 is used to rotate in the opposite direction, driving the winch drum 14 to rotate in the opposite direction. The winch drum 14 drives the wire rope 15, the ring support beam 3, and the ring 4 to descend. When the three rings 4 descend to the same level as the three GIL cylinders, the drive motor 115 is stopped, the electromagnet 120 loses power, and the brake gear 119 loses electromagnetic attraction and resets under the action of the tension of the spring 122, meshing with the meshing gear 118. The shaft of the lifting motor 115 is locked and cannot rotate. The height of the three rings 4 is locked to prevent the GIL cylinder from falling.

[0120] Close the two semicircular claw hooks 43 of the three lifting rings 4, reinstall the buckle 45 under the three lifting rings 4, insert the buckle 15 into the through hole in a straight position, and rotate the rotating clamp 452 of the buckle 45 counterclockwise so that the rotating clamp 452 of the buckle 45 forms an angle of 90 degrees with the static clamp 451. The two semicircular claw hooks 43 of the lifting ring 4 are locked and cannot be separated.
