Description

Technical Field

[0001] This invention belongs to the field of rotor piercing technology, specifically a device for piercing the rotor of a synchronous condenser. Background Technology

[0002] A synchronous condenser, as a special type of synchronous motor, typically employs a salient-pole rotor with excitation and damping windings. The rotor is heavy, long axially, and has high rotational inertia, and often incorporates water-cooling or hydrogen-cooling systems for heat dissipation. During rotor insertion / installation, it is crucial to ensure a uniform air gap between the rotor and the stator core (usually within the range of a few millimeters to tens of millimeters). Any slight deviation or tilt can cause the rotor poles to scrape or collide with the stator cavity wall, leading to serious accidents such as deformation of the stator silicon steel sheets, damage to the bar insulation, leakage in the water-cooling pipes, or even short circuits in the windings. Traditional methods rely on multiple workers surrounding the stator, visually assessing the air gap distance at multiple points. However, limited by the confined internal space, viewing angle deviations, and human error, real-time, accurate, full-circumference monitoring is difficult to achieve, resulting in a high risk of misjudgment. Currently, rotor insertion requires precise coordination with large machinery such as gantry cranes. However, during the actual rotor insertion process, the rotor may shift due to factors such as unbalanced traction force and force point misalignment. The rotor insertion process for synchronous condensers typically relies on manual observation to determine if the rotor collides with the stator wall. During rotor insertion, multiple workers surround the stator to observe the distance between the rotor and the stator inner wall. Because the space inside the synchronous condenser stator is small, the workers' field of vision is very limited, and visual observation is prone to distorted angles, leading to misjudgments of the surrounding air gap length. If the rotor collides with the stator cavity during insertion, it can cause minor wear and paint damage to the cavity, or even severe damage to the equipment's water-cooling pipes and coils, seriously affecting the operation of the synchronous condenser. Furthermore, power plants use factory-supplied or self-made rail-mounted trolleys to carry the rotor, but these devices often employ ordinary gear or chain drives, lacking effective self-lubrication and waste management mechanisms. After long-term use, the gear meshing surface suffers severe dry wear, producing a large amount of metal shavings. These shavings are easily left in the meshing area or track, further aggravating wear, increasing resistance, and even causing transmission jamming or sudden resistance fluctuations, affecting the smoothness of the pull-out process. In view of this, a device for drilling through the rotor of a camera is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: Currently, the rotor insertion operation requires precise coordination with large machinery such as gantry cranes. However, during the actual rotor insertion process, the rotor may shift due to factors such as unbalanced traction force and force point misalignment. The rotor insertion process of the synchronous condenser usually relies on manual observation to determine whether the rotor collides with the cavity wall. During rotor insertion, multiple workers surround the stator to observe the distance between the rotor and the stator inner wall. Due to the small space inside the synchronous condenser stator cavity, the workers' field of vision is very limited, and visual observation is prone to distorted perspectives, leading to misjudgments of the air gap length. If the rotor collides with the stator cavity during insertion, it may cause minor wear and paint damage to the cavity, or even serious damage such as deformation of the equipment's water cooling pipes and coils, severely affecting the use of the synchronous condenser. Furthermore, power plants use plant-supplied or self-made rail-mounted trolleys to carry the rotor, but these devices mostly use ordinary gear or chain drives and lack effective self-lubrication and waste management mechanisms. After long-term use, the gear meshing surfaces suffer severe dry wear, producing a large amount of metal shavings. These shavings are easily left in the meshing area or track, further aggravating wear, increasing resistance, and even causing transmission jamming or sudden resistance fluctuations, affecting the smoothness of the pull-out process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a device for drawing through a synchronous condenser rotor, comprising a traveling track, a traveling mechanism, an auxiliary seat, and a rotor body; The auxiliary seat and the traveling mechanism are both mounted on the traveling track, the bearing mechanism is mounted on the traveling mechanism, and the rotor body is mounted on the auxiliary seat and the bearing mechanism; The walking mechanism includes a walking seat, a first walking wheel, and a drive seat.

[0009] As a preferred technical solution for a device for drawing through a synchronous condenser rotor, the transmission channel includes a driven cavity, an intermediate cavity, and a driving cavity. The driven cavity, intermediate cavity, and driving cavity are interconnected. A flow transfer cavity is provided at the upper part of the connection between the driven cavity and the intermediate cavity and the connection between the intermediate cavity and the driving cavity. A channel is provided between the flow transfer cavity and the driven cavity, intermediate cavity, and driving cavity for guiding flow.

[0010] As a preferred technical solution for a device for drawing a synchronous condenser rotor, the transmission assembly includes an intermediate wheel, a driving wheel, a driven wheel, and a driven shaft. The intermediate wheel is hinged in an intermediate cavity, the driving wheel is hinged in a driving cavity, and the driven wheel is rotatably connected in a driven cavity. A driving shaft is mounted at the axial position of the driving wheel. The driving shaft is connected to the output end of an electric drive unit, which drives the driving shaft to rotate the driving wheel. The intermediate wheel, driving wheel, and driven wheel are connected in a transmission-type meshing transmission. A driven shaft is mounted at the axial position of the driven wheel, and the driven shaft is connected to a traveling wheel.

[0011] As a preferred technical solution for a device for piercing the rotor of a synchronous condenser, a curved frame is installed along the inner edge of the transmission channel. The curved frames are installed in pairs, and a separation net is provided at the two low points of the pair of curved frames. The separation net is used to collect and temporarily store the waste debris from the wear of the transmission components. A guide frame is installed in the middle of the pair of curved frames. The guide frame is located below the meshing position of the transmission components, which can facilitate the discharge of the waste debris from the wear between the two components onto the curved frame.

[0012] As a preferred technical solution for a device for pulling through a phase shifter rotor, a second gyratory cavity is provided on the inner edge of the traveling seat, a second rotating disk is arranged on the circumferential surface of the driven shaft, the second rotating disk is rotatably connected in the second gyratory cavity, and sealing plates are arranged at equal included angles on the outer contour of the second rotating disk. The space between each pair of sealing plates is defined as a cavity, wherein the structure arranged along the inner edge of the driven cavity is the same as the structure arranged along the inner edge of the active cavity.

[0013] As a preferred technical solution for a device for drawing through the rotor of a phase shifter, a guide port is provided on the inner edge of the top of the second gyratory cavity, and the guide port and the gyratory cavity are connected by an oblique channel.

[0014] As a preferred technical solution for a device for drawing and inserting a phase shifter rotor, a first rotary cavity is provided between the second rotary cavity and the driven cavity.

The outer contour of the first rotary disk is provided with a first linkage frame and a second linkage frame distributed at equal angles. The first linkage frame and the second linkage frame are located in different positions in cavities A and B to meet the forward and reverse rotation requirements of the driven shaft.

[0015] The beneficial effects of this invention are: 1. By driving the driven shaft to rotate the disc, linkage frame, baffle, inclined channel, and transfer chamber, the maintenance fluid can be automatically directed to the key meshing parts of the drive wheel, intermediate wheel and driven wheel when the traveling mechanism is in forward and reverse rotation. This significantly improves the lubrication effect of the gear meshing surface, reduces dry wear and extends the service life of the traveling mechanism. 2. Through the combined design of curved frame, guide frame and separation net, the metal shavings generated by meshing can be effectively separated from the maintenance fluid. The waste shavings are blocked on the separation net, and the clean maintenance fluid continues to participate in circulation or dripping for use, avoiding the repeated entry of shavings into the meshing area to cause secondary wear or scratches, which greatly improves the reliability and long-term stability of the transmission system. 3. Traditional gear-driven walking devices usually require periodic shutdowns for lubrication and cleaning of accumulated debris. However, this device achieves continuous and precise fluid supply and automatic isolation of waste debris during operation, eliminating the need for excessive addition of maintenance fluid, reducing the number of manual maintenance operations and downtime, and lowering overall operation and maintenance costs. 4. The traveling mechanism, load-bearing mechanism, and auxiliary seat are all integrated on the same track system, making the whole device flexible to move and occupying relatively little space, which is convenient for deployment and operation in field environments such as power plants and substations; 5. Through the high-precision rolling fit between the traveling wheel and the track, the stable meshing transmission of the transmission components, the double-point wedge and clamp-shaped co-fixing of the load-bearing mechanism and the auxiliary seat, the electric constant torque drive, and the real-time supply of clean maintenance fluid by the self-lubricating system, the rotor moves more continuously and the resistance is more uniform throughout the entire insertion / extraction stroke. This significantly reduces jamming, shaking, or intermittent jamming, improving the smoothness, safety, and success rate of operation. It is especially suitable for on-site operation of long and heavy rotors.

A driving shaft 208a is mounted at the axial position of the driving wheel 208 and is connected to the output end of the electric drive component 203a. The electric drive unit 203a drives the drive shaft 208a, causing the drive wheel 208 to rotate.

The outer contour of the rotating disk 214 is provided with a linkage frame 214a and a linkage frame 214b that are distributed at equal angles.

Reference Figure 2 The bearing mechanism 300 includes a bracket 301, a screw 302, and a wedge seat 303. The bracket 301 is mounted on the traveling seat 201, and the wedge seat 303 is telescopically mounted on the traveling seat 201. The screw 302 is threaded onto the bracket 301, and the screw 302 and the wedge seat 303 are rotatably connected. When the screw 302 is turned, the wedge seat 303 can telescopically move under the action of the bracket 301, which can facilitate the bearing of rotor bodies 500 of different specifications. A gasket 304 is installed on the inner edge of the wedge seat 303. The gasket 304 is used to protect the rotor body 500 when placed on the wedge seat 303. A clamp 305 is installed on the wedge seat 303 by bolts. The clamp 305 is used to restrict the rotor body 500 and prevent the rotor body 500 from shaking.

[0034] Reference Figure 3 The auxiliary seat 400 includes a support seat 401, a second traveling wheel 402, a second wedge seat 403, and a second clamp 404. The second traveling wheel 402 is installed at the bottom of the support seat 401, and the second traveling wheel 402 contacts the traveling track 100. The second wedge seat 403 is installed on the support seat 401 to assist in bearing the rotor body 500. The second clamp 404 is installed on the support seat 401 by bolts, and the second clamp 404 is used to restrict the rotor body 500 and further help to prevent the rotor body 500 from shaking.

[0035] This implementation achieves the following: First, the rotor body 500 is hoisted to a designated position. By continuously adjusting the placement of the rotor body 500 on the bearing mechanism 300 and the auxiliary seat 400, the rotor body 500 and the shaft center in the stator bore are accurately aligned. After checking that all parts are in good condition, the electric drive unit 203a is operated to start the electric wire pulling trolley. The electric wire pulling trolley tows the rotor body 500 towards the outlet end. During the driving process of the electric drive unit 203a, the drive shaft 208a rotates the drive wheel 208, and the intermediate wheel 207 and the driven wheel 209 rotate under the meshing action. The driven wheel 209 rotates via the driven shaft 209a, causing the traveling wheel 202 to rotate. This causes the curved frame 210 to change position on the traveling track 100, allowing the rotor body 500 to be pulled through. During the rotation of the intermediate wheel 207, the driving wheel 208, and the driven wheel 209, the driven shaft 209a drives the rotating disk 219 and the sealing plate 220 to rotate. During this process, the maintenance fluid enters the gyratory cavity 216 through the transfer channel 212 and remains in the cavity. At this time, the rotating disk 214 also rotates with the rotating disk 219, and at 204a, it abuts against the baffle 2. When the baffle 213 is at the corner, the transfer channel 212 is directly opposite the cavity, allowing the maintenance fluid to enter the cavity more effectively. As the movement continues, the baffle 213 is squeezed, temporarily closing the transfer channel 212. At this moment, a certain amount of maintenance fluid is stored in the cavity. When the cavity moves to the guide port 217 position, influenced by the inclined channel 218, the maintenance fluid in the cavity will flow through the guide port 217 and the inclined channel 218 into the transfer cavity 211. The transfer cavity 211 is directly opposite the meshing position of the driven wheel 209 and the intermediate wheel 207, thus enabling precise maintenance at the meshing point. According to the above, when the driven shaft 209a is... During rotation, cavity B transmits the maintenance fluid. When the driven shaft 209a rotates in reverse, cavity A transmits the maintenance fluid, ensuring that the rotor body 500 can transmit the maintenance fluid during insertion and withdrawal. After the maintenance fluid reaches the meshing position, it drips onto the guide frame 210b. Since the edge of the guide frame 210b is provided with hooks, the maintenance fluid can be guided to the curved frame 210 and then guided to the separation screen 210a due to its shape. At this time, the waste in the maintenance fluid will be blocked by the separation screen 210a to ensure the cleanliness of the maintenance fluid at the meshing position, and the required oil does not need to be more than half full during operation.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
