Description

Technical Field

[0001] The invention belongs to the technical field of phase regulators, and in particular relates to a tool for disassembling and assembling rotors on site of phase regulators. Background Art

[0002] Under the "dual carbon" goal, my country's power structure is undergoing major changes. The proportion of synchronous power sources dominated by thermal power units has decreased, and new energy sources dominated by wind power and photovoltaic power have gradually developed into the main power sources that dominate in terms of capacity and power. However, the relatively poor grid-related characteristics of new energy sources cannot fully compensate for the role of synchronous power sources in grid stability, and the new power system dominated by new energy sources has problems such as insufficient system inertia, grid overvoltage, and insufficient local short-circuit capacity.

[0003] In order to solve the limitation of transient overvoltage in the sending-end system on the DC transmission power, the new energy sending-end system needs to be equipped with a large number of phase-shifting units. However, new energy power generation sites such as wind farms and photovoltaic power generation collection stations have the characteristics of randomness, intermittency and instability. New energy power generation sites need to be equipped with small phase-shifting units to meet the requirements of the power grid, and currently they are mainly equipped with 10Mvar~100Mvar distributed air-cooled phase-shifting units.

[0004] However, the application site of this type of phase regulator is generally simple, with small factory space and no crane lifting device, which makes the traditional method of lifting and disassembling the rotor unapplicable. Summary of the invention

When the first rotor bracket or the second rotor bracket plays a supporting role, only the rolling elements and other necessary components need to be installed, which is conducive to quickly installing the first rotor bracket and the second rotor bracket in place during the rotor insertion process.

[0018] In one embodiment, a limit block is provided on the bottom plate; when the third rotor support contacts the limit block, the first rotor support moves to one end of the core support assembly.

DETAILED DESCRIPTION

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] The present invention provides a tool for disassembling and assembling a rotor of a phase regulator on site, such as Figure 1 As shown, it includes:

[0049] A bottom plate 3, the stator 16 with the end shield 4 removed is fixed at the upper end of the bottom plate 3, and the upper end surface of the bottom plate 3 is a horizontal plane;

[0050] A connecting assembly, the connecting assembly comprises an extended shaft 5 coaxially fixedly connected to the non-excitation end of the rotor 9 and a fixing frame 11 fixedly connected to the excitation end of the rotor 9;

[0051] The pulling assembly includes a first anchor 1 and a second anchor 13 respectively arranged at both ends of the bottom plate 3, a first cable 2 is arranged between the first anchor 1 and the extension shaft 5, a second cable 12 is arranged between the second anchor 13 and the fixing frame 11, and hand winches are arranged on the first cable 2 and the second cable 12;

[0052] When the core support assembly and the lower part of the core support assembly are placed on the inner surface of the stator 16, Figure 8 As shown, the upper end surface of the core support assembly is a horizontal plane, and the core support assembly includes a plurality of bolts connected in sequence along the axial direction as shown in FIG. Fig. 9 The core support 17 shown;

[0053] The excitation end bearing 10 is installed at the excitation end of the rotor 9, and the excitation end bearing 10 is rollingly connected to the upper end of the bottom plate 3 through a rolling frame 14;

[0054] A rotor support assembly, the rotor support assembly comprising a first rotor support 6 for providing support for the extended shaft 5, a second rotor support 7 for providing support for the non-excitation end of the rotor 9, and a third rotor support 8 for providing support for the non-excitation end of the rotor 9;

[0055] Among them, Figure 1 As shown, the third rotor support 8 is rollingly connected to the upper end of the bottom plate 3 through a rolling body, as shown in FIG. Figure 2 As shown, the first rotor support 6 is rollingly connected to the upper end of the core support assembly through a rolling body, as shown in FIG. Figure 3 As shown, the second rotating bracket is rollingly connected to the upper end of the core bracket assembly through a rolling body, as shown in FIG. Figure 4 As shown, the third rotor support 8 is rollingly connected to the upper end of the base plate 3 via rolling bodies.

[0056] It can be understood that the rotor 9 can be disassembled and assembled by manually adjusting the hand winch, the first rotor bracket 6, the second rotor bracket 7, the third rotor bracket 8, the rolling body, the core support and the rolling frame 14 on the first cable 2 and the second cable 12, which is conducive to the manual disassembly and assembly of the rotor 9 on site without a crane lifting device; by pulling the hand winch on the first cable 2 and the second cable 12 in different directions respectively, the rotor 9 can be moved in a restricted manner to avoid the first cable 2 or the second cable 12 from pulling the rotor 9 too much, and can have a limiting effect on the rotor 9; in addition, the core bracket assembly provides a rolling plane for the rolling bodies at the lower ends of the first rotor bracket 6 and the second rotor bracket 7 to avoid wear of the stator 16 due to the first rotor bracket 6 and the second rotor bracket 7 rolling directly on the stator 16.

[0057] It should be noted that the first rotor bracket 6, the second rotor bracket 7 and the third rotor bracket 8 are welded from multiple steel plates and are provided with handles for easy carrying; the rolling body is a single cylinder for easy movement in a smaller space; and the extending shaft 5 and the fixing frame 11 are provided with pull ears to respectively connect the first cable 2 and the second cable 12.

[0058] In one embodiment, the first rotor support 6 is tied to the extension shaft 5 , and the second rotor support 7 is tied to the rotor 9 .

[0059] It can be understood that such an arrangement is adopted so that the first rotor bracket 6 and the second rotor bracket 7 can be respectively installed in advance at the corresponding positions of the extension shaft 5 and the non-excitation end of the rotor 9. When the first rotor bracket 6 or the second rotor bracket 7 plays a supporting role, only the rolling elements and other necessary components need to be installed. This is conducive to quickly installing the first rotor bracket 6 and the second rotor bracket 7 in place during the insertion of the rotor 9.

[0060] In one embodiment, a limiting block 15 is provided on the bottom plate 3; when the third rotor support 8 contacts the limiting block 15, the first rotor support 6 moves to one end of the core support assembly.

[0061] It can be understood that the stopper 15 can limit the axial movement position of the third rotor support 8; when the third rotor support 8 contacts the stopper 15, it can be determined that the first rotor support 6 moves to one end of the core support assembly.

[0062] It should be noted that when the rotor 9 is axially installed in place, the rolling frame 14 contacts the limit block 15 , so that it is convenient to determine whether the rotor 9 is axially installed in place by whether the rolling frame 14 contacts the limit block 15 .

[0063] In one embodiment, when the first rotor support 6 rolls to the other end of the core support assembly, the second rotor support 7 moves to one end of the core support assembly.

[0064] It is understandable that this arrangement allows the first rotor support 6 to roll to the other end of the core support assembly by means of rolling bodies, and then the second rotor support 7 can be replaced and roll on the core support assembly by means of rolling bodies, thereby facilitating further movement of the rotor 9.

[0065] In one embodiment, when the second rotor support 7 rolls to the other end of the core support assembly, the third rotor support 8 is transferred to the upper end of the base plate 3 .

[0066] It is understandable that the arrangement is such that after the second rotor support 7 rolls to the other end of the core support assembly by means of the rolling body, the third rotor support 8 is replaced and rolls on the bottom plate 3 by means of the rolling body, thereby facilitating the continued movement of the rotor 9.

[0067] In one embodiment, the rotor support assembly includes an adjusting gasket for bolting to the upper ends of the first rotor support 6, the second rotor support 7 and the third rotor support 8, and the rotor support assembly also includes a square box and a washer, and the upper end of the adjusting gasket is bolted to the square box and the washer in turn.

[0068] It is understandable that by installing adjusting gaskets of different thickness specifications, the height of the shim can be adjusted to facilitate the shim to support the rotor 9 or components on the rotor 9, thereby facilitating the leveling of the rotor 9.

[0069] In one embodiment, the washer is a V-shaped washer to facilitate fixing the cylindrical shaft on the rotor 9.

[0070] In one embodiment, a backing plate assembly is included, the lower end surface of the backing plate assembly is attached to the inner circular surface of the stator 16, and the lower end surface of the core support assembly is attached to the upper end surface of the backing plate assembly.

[0071] In one embodiment, the pad assembly includes an insulating pad and a metal pad, the lower end surface of the insulating pad is attached to the inner circular surface of the stator 16, the lower end surface of the metal pad is attached to the upper end surface of the insulating pad, and the lower end surface of the core support assembly is attached to the upper end surface of the metal pad.

[0072] In one embodiment, Fig.10 As shown, the rolling frame 14 includes a rolling frame 1401 and a plurality of rollers 1402 rotatably connected to the rolling frame 1401 , and the plurality of rollers 1402 are distributed along the rolling direction.

[0073] It should be noted that the two ends of the roller 1402 are large cylinders, and the middle part of the roller 1402 is a small cylinder; a plurality of semicircular holes are set on one side of the roller frame 1401, and the two roller frames 1401 are buckled and form a plurality of circular holes for clamping the small cylinders at positions close to each other, so that the plurality of rollers 1402 are rotatably connected to the roller frame 1401.

[0074] The process of inserting the rotor 9 of the present invention is:

[0075] Pull the first cable 2 on the hand chain hoist, pull the second cable 12 on the hand chain hoist in the opposite direction, and the rotor 9 uses the rolling body and the rolling frame 14 at the lower end of the third rotor bracket 8 to move until the third rotor bracket 8 contacts the limit block 15. Figure 2 As shown;

[0076] Use the jack to lift the connecting shaft 5, install the rolling element at the lower end of the first rotor bracket 6, and install the adjusting gasket, square box and shim at the upper end of the first rotor bracket 6, then remove the third rotor bracket 8, the rolling element at the lower end and the adjusting gasket, square box and shim at the upper end, put down the connecting shaft 5 and take out the jack;

[0077] Pull the hand chain hoist on the first cable 2, and pull the hand chain hoist on the second cable 12 in the opposite direction, and the rotor 9 moves by means of the rolling body and the rolling frame 14 at the lower end of the first rotor support 6 until the first rotor support 6 moves to the edge of the core support assembly. Figure 3 As shown;

[0078] Lift the non-excitation end of the rotor 9 with a jack, install the rolling element at the lower end of the second rotor bracket 7, and install the adjusting gasket, square box and shim at the upper end of the second rotor bracket 7, then remove the first rotor bracket 6, the rolling element at the lower end thereof, and the adjusting gasket, square box and shim at the upper end thereof, put down the non-excitation end of the rotor 9 and take out the jack;

[0079] Pull the hand chain hoist on the first cable 2, and pull the hand chain hoist on the second cable 12 in the opposite direction, the rotor 9 uses the rolling body and the rolling frame 14 at the lower end of the second rotor bracket 7 to move, and gradually remove the core bracket 17 of the second rotor bracket 7 away from the end of the extension shaft 5 until the second rotor bracket 7 moves to the edge of the core bracket assembly. Figure 4 As shown;

[0080] Lift the extended shaft 5 with a jack, install the third rotor bracket 8 with a rolling body at the lower end to the lower end of the extended shaft 5, and install an adjusting gasket, a square box and a washer on the upper end of the third rotor bracket 8, then remove the second rotor bracket 7, the rolling body at the lower end thereof and the adjusting gasket, square box and washer at the upper end thereof, put down the extended shaft 5 and take out the jack;

[0081] Remove the remaining core support 17, pull the hand chain hoist on the first cable 2, pull the hand chain hoist on the second cable 12 in the opposite direction, and move the rotor 9 using the rolling body and rolling frame 14 at the lower end of the third rotor support 8 until the rotor 9 is axially installed in place. Figure 5 As shown;

[0082] like Figure 6 As shown, the non-excitation end of the rotor 9 is lifted by a jack, and the non-excitation end bearing 18 is installed at the journal position of the non-excitation end of the rotor 9; Figure 7 As shown, the third rotor support 8, the rolling element at the lower end thereof and the adjusting gasket, the square box and the shim at the upper end thereof are removed, the non-excitation end of the rotor 9 is lowered and the jack is taken out;

[0083] The jack lifts up the fixed frame 11, takes out the rolling frame 14, then puts down the fixed frame 11 and takes out the jack.

[0084] It should be noted that when the rotor 9 is axially installed in place, the hand chain hoist on the second cable 12 is pulled in the opposite direction to the limit position, so as to determine whether the rotor 9 is axially installed in place.

[0085] It should be emphasized that the process of withdrawing the rotor 9 is opposite to the process of inserting the rotor 9.

[0086] In summary, the on-site disassembly and assembly tool for the phase regulator rotor can be used for on-site installation, inspection or maintenance of the phase regulator rotor 9 when there is no large lifting equipment. It has the characteristics of saving time, labor, low cost and simple operation. It can realize the disassembly and assembly of the 100t rotor 9 with very little manpower and material resources.
