Abstract

This invention belongs to the field of pumped storage power station transformer installation technology, specifically a mobile box-type transformer installation platform for pumped storage power stations. It includes a base, with a main unit at one end of the base, a control unit inside the main unit, and a monitoring unit on one side of the control unit. This invention utilizes the contact rebound between a spring-loaded striker and the end face of the rail to control the upright rod to drive the ball head to produce different displacement contacts with the serpentine groove on the inner wall of the screw, thereby achieving different degrees of screw rotation. Subsequently, different displacement contacts are generated between the latch and its outer serpentine groove. Finally, under the control of the transverse wedge plate, the liquid level plate changes the flow direction of the fluid in the spray gun, achieving a linear expression of the spring-loaded striker rebound distance and the spray gun's spray cross-sectional area. This helps maintenance personnel judge the trend and severity of changes in the verticality of the rail, improves the stability and safety of the mobile box-type transformer transfer, increases the service life of the rail and wheels, and reduces transfer costs.

Description

Technical Field

[0001] This invention belongs to the field of transformer installation technology for pumped storage power stations, and specifically relates to a mobile box-type transformer installation platform for pumped storage power stations. Background Technology

[0002] In pumped storage power stations, the installation platform for mobile box-type transformers needs to balance flexibility, stability, and safety; common types of installation platforms include: rail-mounted mobile platforms, sliding hydraulic platforms, modular assembly platforms, and heavy vehicle-mounted platforms.

[0003] Rail-guided transport vehicle: An industrial transport device that moves along a preset track. It receives instructions from a host computer or operating terminal through an electrical control system. The drive motor drives the wheels to rotate on the track according to the instructions, so that the vehicle travels along the predetermined path. During the journey, the guide mechanism ensures that the vehicle always runs along the track and does not deviate. When the vehicle reaches the designated position, the electrical control system controls the brake to stop the vehicle. It is mainly used for heavy-duty, high-frequency and high-precision material handling.

[0004] When the load weight distribution of the track-mounted mobile platform is uneven, it causes the center of gravity of the track to shift, which in turn generates uneven pressure on the track. Under the cumulative effect of aging, the track will deform to different degrees at different positions, until it affects the horizontality and verticality of the track.

[0005] In addition, during the start-up, braking and operation of the mobile platform, dynamic loads are generated. Especially under high-speed operation or frequent start-stop conditions, the impact of dynamic loads causes the track to vibrate. Long-term vibration will inevitably lead to the loosening of the track fixing device, that is, gaps or misalignments appear at the track connection points, which in turn leads to changes in the levelness and verticality of the track.

[0006] At the same time, the track material will expand and contract with temperature changes. In areas with large temperature differences between day and night or obvious seasonal changes, the length and shape of the track will change. If the track expansion joints are not set properly or if effective temperature compensation measures are not taken, the stress generated by thermal expansion and contraction will gradually cause the track to deform, affecting its horizontality and verticality.

[0007] Dust or solid particles accumulating or settling on the track surface can alter the contact state of the track surface, affecting its smoothness. In other words, the wheels of the mobile platform will experience uneven contact with the track due to the presence of these particles or dust during operation. For example, when particles accumulate on one side of the track, the supporting force on that side changes, causing the wheel to deviate during operation. Over time, this can lead to deviations in the track's horizontal and vertical alignment.

[0008] In addition, dust and solid particles can change the frictional characteristics between the wheels and the track, resulting in changes in rolling frictional resistance. During the operation of the mobile platform, uneven frictional resistance will generate additional lateral forces and torques, causing slight displacement and deformation of the track, which in turn affects the levelness and verticality of the track.

[0052] Preferably, the pitch of the serpentine groove on the outer wall of the screw end away from the base is at least twice the pitch of the serpentine groove on the inner wall of the screw end closer to the base.

[0053] The method for monitoring the horizontal and vertical alignment of the track in a track-mounted mobile platform, using the aforementioned mobile box-type transformer installation platform for a pumped storage power station for real-time monitoring, involves the following specific steps:

[0054] S1: First, the control unit, monitoring unit and cleaning unit are moved towards the rail by the overall sliding of the electric slide drawer until the receiving slot is aligned with the rail. At this time, the support, under the support and guidance of the rail, controls the bracket to drive the monitoring unit and cleaning unit towards the Rongwei slot until the vertical cylinder axis intersects with the center line of the rail.

[0055] S2: Then, the monitoring unit moves as a whole through the panel control until the spring striker contacts the rail. After that, the distance the spring striker moves in its axial direction is reflected by the ball head driving the screw to rotate under the control of the upright. At the same time, the buckle slides along the inner wall of the vertical cylinder under the reverse action of the screw until the vertical wedge plate moves towards the panel under the action of the arrow plate.

[0056] S3: Finally, by moving the vertical wedge plate, the degree of interaction between it and the horizontal wedge plate is changed. During this process, the return spring, under its own rebound action, controls the straight rod to drive the liquid level plate to move towards the vertical cylinder axis under the guidance of the face ring. This changes the number of intermittent delivery channels in the spray gun by the liquid level plate, thereby achieving different expressions of the spray gun spraying cross-sectional area under different degrees of impact of the spring striker.

[0057] The present invention has the following beneficial effects:

[0058] 1. This invention utilizes the contact rebound between the spring striker and the end face of the rail to control the upright rod to drive the ball head to produce different displacement contacts with the serpentine groove on the inner wall of the screw, thereby expressing different degrees of screw rotation. Subsequently, the latch, while the screw is rotating, produces different displacement contacts with its outer serpentine groove, thus achieving an extended range expression of the spring striker's movement distance. Until the support column is lifted, the control arrow plate drives the vertical wedge plate to make different degrees of same-direction movement. Finally, under the control of the horizontal wedge plate, the liquid level plate changes the flow area of ​​the fluid in the spray gun, achieving a linear expression of the spring striker's rebound distance and the spray gun's spray cross-sectional area. This helps maintenance personnel judge the trend and severity of changes in the verticality of the rail, prevents derailment accidents, reduces collision risks, and improves the stability and safety of transferring mobile box-type transformers. At the same time, it helps to improve the service life of the rail and wheels, reduce transfer costs, that is, reduce the additional resistance caused by the platform to overcome uneven or tilted rails, reduce energy consumption, and achieve energy saving and efficiency improvement.

[0059] 2. This invention controls the movement of the horizontal plate via an electric telescopic rod until the spring shovel contacts the horizontal end face of the rail. Afterward, the electric telescopic rod continues to control the horizontal plate's movement until the spring shovel and elastic scraper separate from each other. At this point, the elastic scraper, under its own rebound, contacts the vertical end face of the rail and maintains a certain interaction force. Ultimately, as the spring shovel and elastic scraper move along with the rail-guided transport vehicle, they continuously generate relative motion with different areas of the stationary rail. This achieves the scraping and cleaning of solid particles and dust accumulated or scattered on the rail end face. Compared to traditional rigid scraping methods, both the spring shovel and elastic scraper can provide buffer protection for fragile or finely processed parts of the workpiece surface during scraping, preventing excessive pressure and damage. Simultaneously, the telescopic nature of the spring shovel and elastic scraper in the feed direction allows for more uniform material removal during scraping.

[0060] 3. This invention provides stable support and protection to the ring tube through the ear seat, and then provides stable support to the plumb rod through the ring tube. In this way, the mouth ring provides stable radial traction and support to the spring striker in the direction of the plumb rod axis, thereby reducing the degree of loss of rebound accuracy caused by radial runout of the spring striker during long-term operation. In this process, the contact friction form between the mouth ring and the spring striker is changed by the ball bearings, reducing the friction force and further improving the monitoring accuracy and service life of the spring striker.

[0086] It should be noted that the terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0087] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0092] First, the mobile box-type transformer is placed as a whole onto the designated area on the end face of the rail transport vehicle 23 using an external hoisting mechanism (the purpose of the rail transport vehicle 23 being a split type is to provide a more portable transfer method, while also helping maintenance personnel to inspect the internal components of the rail transport vehicle 23).

[0093] Next, driven by the hydraulic rod 25, the corner pad 26 approaches and contacts the mobile box-type transformer. On the one hand, it provides stable support and clamping to the mobile box-type transformer, improving its stability during movement, reducing the probability of center of gravity shift, and protecting the horizontality and verticality of the rail 22. On the other hand, it reduces the dynamic load impact on the rail transport vehicle 23 during the movement of the mobile box-type transformer, which helps to improve the movement stability of the rail transport vehicle 23, reduce energy consumption, and increase efficiency.

[0094] Finally, the rail-guided transport vehicle 23 is driven by wheels 24 to drag the mobile box-type transformer to the designated position. Specifically, the wheels 24 can be driven to rotate by an external motor (in practice, the movement path can be remotely controlled by an intelligent control system composed of PLC and GPS positioning).

[0095] Angle steel plate 27 and corner post 28: Angle steel plate 27 and corner post 28 further enhance the connection stability and divisibility between the split rail transport vehicles 23, and improve the flexibility of the rail transport vehicles 23 in actual use.

[0106] With the support and guidance of the rail 33, the bracket 34 controls the port bracket 35 to move the monitoring unit 4 and the cleaning unit 5 together from one end of the rail 33 away from the receiving groove 32 to the other end, until the panel 36 is directly opposite the rail 22. In specific implementation, the support 34 can be driven to reciprocate by an electric slider.

[0107] U-shaped frame 38: The U-shaped frame 38 further enhances the connection rigidity and stability between the panel 36 and the bracket 35, while providing a reasonable installation environment for the remaining components of the monitoring unit 4, reducing the redundancy and messiness of the wiring later.

[0108] Reinforcing rib 39: Further improves the structural strength of the U-shaped frame 38, and in conjunction with the U-shaped frame 38, further improves the layout ecology of the monitoring unit 4 and the cleaning unit 5;

[0109] Electric slide 31: When the monitoring unit 4, control unit 3 or cleaning unit 5 malfunctions, it can slide in and out as a whole, reducing the maintenance difficulty for maintenance personnel. In practice, the electric slide 31 can be moved by an electric slider. In addition, the electric slide 31 can adjust the contact area between the spring striker 43 in the monitoring unit 4 and the horizontal plane of the rail 22, thereby more comprehensively assisting the monitoring unit 4 in completing the real-time monitoring of the verticality of the rail 22 during the driving process with completeness and accuracy.

[0110] The ear seat 431 provides stable support and protection to the ring tube 432, and the ring tube 432 provides stable support to the vertical rod 433. In this way, the mouth ring 434 provides stable radial traction and support to the spring striker 43 in the axial direction of the vertical rod 433. This reduces the degree of loss of rebound accuracy caused by radial runout of the spring striker 43 during long-term operation. In this process, the ball bearing 435 changes the contact friction form between the mouth ring 434 and the spring striker 43, reduces friction, and further improves the monitoring accuracy and service life of the spring striker 43.

[0111] The specific linear change process of the spray gun 421 spray cross-sectional area under different rebound degrees of the spring striker 43 (different expression forms of feedback of verticality of different areas of the track 22 by the monitoring unit 4):

[0112] Taking the presence of a protrusion on the horizontal plane of the track 22 as an example (in the initial state, the spring striker 43 maintains a certain interaction force with the track 22):

[0113] First, during the operation, when the spring striker 43 contacts the protrusion (to varying degrees) on the end face of the rail 22, the spring striker 43, under the combined action of the reverse lifting of the protrusion and the guidance of the vertical cylinder 41 and the washer ring 42, drives the vertical rod 44 to move along the axis of the vertical cylinder 41 towards the panel 36 area. During this process, the ball head 45, driven by the vertical rod 44, causes the screw 46 to rotate at a certain angle (in specific implementation, an annular hole (not shown) is opened at the end of the screw 46 near the washer ring 42, and a serpentine groove (not shown) is opened on the inner wall of the annular hole. The serpentine groove slides and engages with the ball head 45. When the vertical rod 44 drives the ball head 45 to move along the axis of the vertical rod 44, the ball head 45 forces the serpentine groove to drive the screw 46 to rotate. That is, through the engagement between the ball head 45 and the serpentine groove, the axial movement of the vertical rod 44 is converted into the rotation of the screw 46).

[0114] Next, during the rotation of the screw 46, the latch 48, guided by the serpentine groove (not shown) on the outer wall of the screw 46 (refer to the movement of the ball head 45), drives the straight column control arrow plate 412 to move away from the spring striker 43. (During this process, the inner wall of the vertical cylinder 41 provides further guidance and support to the latch 48 in the moving state, which helps to improve the movement stability of the support column 411). After that, under the combined action of the arrow plate 412 and the guide of the cover box 413, the vertical wedge plate 414 gradually reduces the degree of interaction with the horizontal wedge plate 415. In specific implementation, the cross-sectional shape of the interaction end of the vertical wedge plate 414 and the horizontal wedge plate 415 is an isosceles right trapezoid.

[0115] Finally, under the control of the straight rod 417, the transverse wedge plate 415 moves continuously towards the vertical section of the cover box 413. During this process, the return spring 418, due to its own compression rebound (in the initial state, the return spring 418 is in a compressed state, and the spring elastic coefficient of the spring pin 43 itself is greater than the elastic coefficient of the return spring 418), drives the straight rod 417 to control the liquid level plate 419 to move towards the vertical wedge plate 414 (in the initial state, the liquid level plate 419 completely blocks the flow channels at the inlet and outlet ends of the spray gun 421). In this way, the spraying cross-sectional area of ​​the spray gun 421 is expressed differently under different degrees of impact from the spring pin 43 (for example, when the spring pin 43 is in the first-level rebound zone, the liquid level plate 419 temporarily blocks the internal fluid flow channel of the spray gun 421 in three areas, and so on, gradually unblocking the blocked areas).

[0116] Specific implementation plan for spraying coating at the exit end of spray gun 421:

[0117] The pressure pump 423 and water valve 424 are connected by a hose, and the pressure pump 423 and angle valve 425 are connected by another hose. Then, when the electrode ring 47 contacts the telescopic spring needle 49, the external PLC control system converts the aforementioned contact signal into the opening and closing signal of the pressure pump 423. This enables the pressure pump 423 to pump the paint stored in the water tank 37 to the spray gun 421 when the spring needle 43 rebounds. Finally, the paint of different cross-sectional areas is sprayed onto the horizontal end face of the rail 22 through the spray gun 421, thereby achieving the expression of different degrees of verticality change.

[0118] The simultaneous contact between electrode ring 47 and telescopic spring pin 49 (at different positions) is a self-testing process for the extension accuracy of screw 46 (i.e., under the cumulative effect of time, the engagement accuracy between buckle 48 and the serpentine groove on the outer wall of screw 46, and the engagement accuracy between ball head 45 and the serpentine groove on the inner wall of screw 46, will both show different degrees of wear).

[0119] The two symmetrically distributed buckles 48 need to maintain the same moving distance during actual movement. That is, the telescopic spring pins 49 at different positions need to contact the electrode ring 47 at the same time. This ensures that the buckles 48 move the same distance when the screw 46 rotates at the same angle. This indirectly improves the mutuality and relativity between the spraying cross-sectional area of ​​the spray gun 421 and the rebound of the spring pin 43, and improves the monitoring accuracy of the spring pin 43 on the perpendicularity of the rail 22.

[0120] The purpose of making the pitch of the serpentine groove on the outer wall of the end of the screw 46 away from the base 1 at least twice that of the pitch of the serpentine groove on the inner wall of the end of the screw 46 close to the base 1 is to enhance the "magnified" expression of the movement distance of the latch 48 under the slight deformation of the spring striker 43, and improve the sensitivity of the spray gun 421 to the spring striker 43.

[0121] Reference Figure 5 and Figure 14 It is known that the cleaning unit 5 includes: a fitting seat 51, two of which are symmetrically fitted and snapped onto the horizontal section of the bracket 35; an electric telescopic rod 52, which is snapped onto the middle position of the end face of the fitting seat 51 near the receiving groove 32; a horizontal plate 53, which is snapped onto the end of the two electric telescopic rods 52 in the same group away from the fitting seat 51; a vertical frame 54, which is snapped onto the middle position of the end face of the horizontal plate 53 near the fitting seat 51; a spring shovel 55, which is located on the side of the horizontal plate 53 away from the fitting seat 51, and the spring shovel 55 is slidably fitted and snapped onto both the horizontal plate 53 and the vertical frame 54; two plates 56, two of which are symmetrically fitted and snapped onto both ends of the end face of the horizontal plate 53 away from the fitting seat 51; and an elastic scraper, which is slidably fitted and snapped onto the middle position of the plate 56.

[0122] Reference Figure 7 and Figure 13 It can be seen that a shaft platform 511 is rotatably installed on the horizontal section of the U-shaped frame 38 away from the vertical cylinder 41. A pressure ball 512 is snapped onto the inner wall of one side of the shaft platform 511, and a driven gear 513 is snapped onto the outer wall of the shaft platform 511. A stepper motor 514 is snapped onto the end face of the horizontal section of the U-shaped frame 38 near the vertical cylinder 41, and a drive gear 515 that meshes with the driven gear 513 is snapped onto the output end of the stepper motor 514.

[0123] The cleaning unit 5 cleans the solid particles and dust on the horizontal and vertical end faces of the track 22:

[0124] First, the fitting seat 51 moves to the designated position under the control of the mouth bracket 35 until the spring shovel 55 is distributed opposite to the rail 22. Then, the electric telescopic rod 52 controls the horizontal plate 53 to drive the upright frame 54 to move towards the rail 22 (in the initial state, the spring shovel 55 is in its natural state, and the spring shovel 55 is located between two opposite elastic scrapers).

[0125] Next, while the spring shovel 55 is in contact with the horizontal end face of the rail 22 and maintains a certain interaction force, it continues to extend through the electric telescopic rod 52 until the spring shovel 55 disengages from the elastic scraper and the elastic scraper contacts the vertical end face of the rail 22.

[0126] Ultimately, the overall movement of the rail-guided trolley 23 causes the spring shovel 55 and the elastic scraper to continuously and flexibly scrape away solid particles and dust on the end face of the rail 22 during the following process; conversely, before stopping for maintenance, the electric telescopic rod 52 must be used to control the horizontal plate 53 to drive the spring shovel 55 and the elastic scraper back to their initial positions to avoid collision between the extended cleaning unit 5 and the electric slide 31.

[0127] It is hereby noted that: during the process when the spring shovel 55 is no longer in contact with the rail 22, due to the width limitation of the vertical section of the rail 22, when the spring shovel 55 is in its natural state again, it is still between the two elastic scrapers (at this time, the elastic scrapers are still in contact with the rail 22, and when the elastic scrapers are separated from the rail 22, they will clamp the spring shovel 55 again due to their own rebound properties).

[0128] In actual use, the spray guns 421, which are symmetrically distributed on the outside of the vertical cylinder 41, do not work simultaneously:

[0129] Typically, the spray gun 421 operates behind the direction of travel, thus enabling the spring striker 43 to monitor first and the spray gun 421 to spray later.

[0130] Specific control method: The stepper motor 514 controls the drive gear 515 to rotate. Then, the driven gear 513, under the meshing action of the drive gear 515, synchronously drives the shaft 511 to rotate 180 degrees until the pressure ball 512 is at the same end as the working spray gun 421. Finally, when the spring striker 43 rebounds and contacts the pressure ball 512, the external PLC control system converts the aforementioned contact signal into the working start and stop signal of the spray gun 421.

[0131] Special note: Regarding the method for measuring horizontality in this invention, referring to the verticality measurement scheme, in specific implementation, monitoring units 4 can be added to both sides of the U-shaped frame 38 (please refer to the appendix). Figure 15 As shown by the dashed lines at points a and b, the horizontality monitoring unit 4 is placed in a position that is vertically distributed with the verticality monitoring unit 4 in terms of spatial layout.

[0132] The working principle of the mobile box-type transformer installation platform for pumped storage power station provided by the present invention is as follows: First step: First, the electric sliding drawer 31 slides as a whole, and the control unit 3, monitoring unit 4 and cleaning unit 5 move towards the rail 22 until the receiving slot 32 is aligned with the rail 22. At this time, under the support and guidance of the rail 33, the support 34 controls the bracket 35 to drive the monitoring unit 4 and cleaning unit 5 to move towards the trough until the axis of the vertical cylinder 41 intersects with the center line of the rail 22.

[0133] Step 2: Next, the monitoring unit 4 is moved as a whole by controlling the panel 36 until the spring striker 43 contacts the rail 22. After that, the movement distance of the spring striker 43 in its axial direction is reflected by the ball head 45 driving the screw 46 to rotate under the control of the upright rod 44. At the same time, the buckle 48 slides along the inner wall of the vertical cylinder 41 under the reverse action of the screw 46 until the vertical wedge plate 414 moves towards the panel 36 under the action of the arrow plate 412.

[0134] Step 3: Finally, by moving the vertical wedge plate 414, the degree of interaction between it and the horizontal wedge plate 415 is changed. During this process, the return spring 418, under its own rebound action, controls the straight rod 417 to drive the liquid level plate 419 to move towards the axis of the vertical cylinder 41 under the guidance of the face ring 416. This changes the number of intermittent delivery channels in the spray gun 421 provided by the sealing plate 422 to the liquid level plate 419, thereby achieving different expressions of the spraying cross-sectional area of ​​the spray gun 421 under different degrees of impact of the spring striker 43.
