Description

Technical Field

[0001] The invention relates to the technical field of generator rotors, and in particular to a generator rotor winding coil cleaning and shaping support device. Background Art

[0002] Large generators generally need to be inspected and maintained after a service cycle, and the winding coil is an important component of large generators, and its purpose is to convert electrical energy into magnetic energy. At present, the winding coils in large generators are generally made of copper bars, which makes it easier for the entire winding coil to pass a larger current and reduce its own resistance. However, the overall size is large and the weight is heavy, and it often requires multiple workers to move it at the same time. Due to the resistance inside, the winding coil will inevitably heat up during the operation process. Since the winding coil generates a lot of heat for a long time during the operation process, it is easy to react with oxygen and water vapor in the air to form a copper oxide layer. The resistance of the copper oxide layer is much greater than the resistance of pure copper or copper alloy used in conventional winding coils, which further increases the heat generation of the winding coil, and may also cause the coil to overheat and cause the motor to burn out. Therefore, large generators have a maintenance cycle. After the maintenance cycle, the entire motor will be dismantled and divided into parts for maintenance. The main maintenance work of the winding coil is mainly divided into checking whether the insulation layer is damaged, replacing the insulation layer, and removing the oxide layer on the surface of the copper bar. The work of checking whether the insulation layer is damaged and replacing the insulation layer is done after removing the oxide layer on the surface of the copper busbar. Therefore, it is very important to remove the oxide layer on the surface of the copper busbar during the inspection and maintenance of the winding coil.

[0003] At present, when workers polish and remove the oxide layer on the surface of the copper bar, they generally use some bracket structures to support and separate the winding coils. The most common way is to support each layer with a mesh plate or a simple rod-shaped structure, and then these mesh plates or rod-shaped structures are placed on a specific bracket. Such a bracket structure is very bulky and inflexible during use, and cannot adapt to winding coils of different sizes. When it is necessary to take and place the winding coil, the entire layer of mesh plates or rod-shaped structures needs to be dismantled or built, which is very troublesome. Moreover, in the process of installing or dismantling the entire winding coil, at least two workers are often required to move the same layer of copper bars, and then a third worker may only need to flip the mesh plate or rod-shaped structure for the part of the winding coil and place it on a specific bracket or remove it from the bracket. It can be seen that the current structure used to support the winding coil is very inconvenient to use, and requires multiple people to operate at the same time, with high labor costs; at the same time, the overall structure is different and can adapt to the use of winding coils of various specifications.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] like Figures 1 to 7 As shown, the present invention provides a generator rotor winding coil cleaning and shaping support device, including a base frame 1, a lifting assembly 3 and a stacking frame 2; the lifting assembly 3 can be lifted and installed on the base frame 1, and the stacking frame 2 is provided with a plurality of groups, each group of the stacking frames 2 includes a support body 22 and a plurality of movable latches 23, one end of the support body 22 is provided with an opening slot 24 along the length direction, and the other end of the support body 22 is adjustably mounted on the lifting assembly 3; the opening slot 24 runs through both sides of the support body 22, and the support body 22 is provided with a plurality of through holes 25 on both sides of the opening slot 24, and a plurality of the movable latches 23 can be movably inserted in the through holes 25 to divide the opening slot 24 into a plurality of isolation spaces 21 that can accommodate the winding coils to pass through; a pin driving block 28 is slidably installed on the support body 22 to insert the movable latch 23 into the through hole 25 or pull it out from the through hole 25. In the present application, the entire copper bar is wound into a winding coil in a zigzag manner, and the copper bar is basically a flat strip structure. Therefore, in the present application, the winding coil of each layer is in a corresponding isolation space 21, which is convenient for the copper bar to be polished layer by layer. In addition, in the present application, the width of the opening slot 24 is greater than the width of the copper bar, which is convenient for the operator to flip the copper bar during polishing, thereby improving the convenience of the entire polishing. In the present application, the movable latch 23 can be a conventional pin, that is, one end has a terminal, and the diameter of the terminal is greater than the diameter of the perforation 25. The stacking device can also be used as an auxiliary tool for the later coating of the copper bar with an insulating layer, which is very convenient.

[0031] In the present application, the base frame 1 can be used as a basic structure, so the lifting assembly 3 can be installed on or below the base frame 1, so that it is convenient for workers to stack the entire winding coil on the stacking rack 2 and layer the winding coil through the isolation space 21. The weight of a winding coil in a large generator is generally dozens or even hundreds of pounds. In order to facilitate workers to carry and hook the copper bar; in the present application, it is preferred that the stacking rack 2 is arranged below the lifting assembly 3, and a movable connection structure is adopted, so that workers can place the winding coil in the isolation space 21 layer by layer. The isolation space 21 can be some open slot structures, or some semi-enclosed structures, such as a lockable hook structure; as long as the structure of placing each layer of copper bar in layers of the winding coil can be realized. Since the winding coil is generally a circular or rectangular structure, for this reason, in the present application, four groups of stacking racks 2 are preferably arranged to facilitate stable support of the entire winding coil and avoid excessive deformation of the winding coil due to its own weight. In addition, in order to facilitate turning over the entire copper bar during the grinding process, the height of the isolation space 21 along the length direction of the support body 22 is greater than the thickness of the winding coil, that is, the distance between any two adjacent movable pins 23 is greater than the thickness of the winding coil. In one embodiment of the present application, in order to better record the number of turns of the entire winding coil, a digital mark can be designed on the outer wall of the support body 22.

[0032] See also Figures 1 to 3 The main purpose of designing the lifting assembly 3 in this application is to better facilitate the workers to hook the winding coils layer by layer in the isolation space 21, reduce the height of the workers lifting the winding coils, and thus reduce the labor intensity. The lifting assembly 3 includes a crossbeam 31 and a longitudinal beam 32. The crossbeam 31 is provided with two groups and can be respectively installed on the two ends of the base frame 1 in a lifting manner. The longitudinal beam 32 is provided with two groups. The two ends of the two groups of longitudinal beams 32 can be slidably installed on the two groups of crossbeams 31 respectively. A telescopic mechanism 33 is provided on any of the longitudinal beams 32, and the output end of the telescopic mechanism 33 is connected to the other group of longitudinal beams 32; the stacking rack 2 is adjustably installed on the longitudinal beam 32. The two groups of longitudinal beams 32 can move closer and farther away from each other. The main purpose of this design is to facilitate the adaptation to winding coils of different diameters. The stacking rack 2 is also positionally adjustable on the same longitudinal beam 32, and can adapt to winding coils of various specifications. The telescopic mechanism 33 can be preferably a telescopic cylinder or an electric cylinder, as long as it can realize the telescopic function. In the present application, the telescopic mechanism 33 is composed of a telescopic motor 331 and a telescopic screw 332, wherein the telescopic motor 331 is installed on any one set of longitudinal beams 32, and one end of the telescopic screw 332 is connected to the telescopic motor 331, and the other end is connected to the other set of longitudinal beams 32 through a screw nut. A slide rail 37 is provided on the crossbeam 31, and both ends of the two sets of longitudinal beams 32 can be slidably installed on the slide rail 37 respectively.

[0033] Furthermore, in the present application, in order to improve the stability of the entire structure, the two groups of the cross beams 31 are connected by a connecting beam 34. The two groups of the cross beams 31 are connected by a connecting beam 34, and the base frame 1 is provided with vertical slots 11 in the areas where the two groups of cross beams 31 are located. The two ends of the two groups of cross beams 31 are respectively slidably installed in the corresponding vertical slots 11, and a lifting mechanism 12 is provided on the base frame 1, and the output end of the lifting mechanism 12 is connected to the connecting beam 34. In the present application, since the entire lifting mechanism 12 has to bear the weight of the entire lifting assembly 3, the stacking rack 2 and the winding coil, in order to improve the stability and carrying capacity, the lifting mechanism 12 in the present application includes a lifting motor 121, and the output end of the lifting motor 121 is set downward, and the output end of the lifting motor 121 is connected to a lifting screw 122, and the lifting screw 122 is connected to the cross beam 31 through a screw nut.

[0034] In order to adjust the distance between the two groups of stacking racks 2 on each group of longitudinal beams 32, an opening and closing mechanism 35 is provided on each group of longitudinal beams 32, and the upper ends of the two groups of stacking racks 2 can be slidably installed on the same longitudinal beam 32. The opening and closing mechanism 35 can be a conventional connecting rod drive structure, or it can be a cylinder drive to achieve the two groups of stacking racks 2 approaching or moving away from each other in the length direction of the longitudinal beam 32. In this application, a slide 36 is provided on each group of longitudinal beams 32, and the upper ends of the two groups of stacking racks 2 are slidably installed in the slide 36, and the opening and closing mechanism 35 is connected to the upper end of the stacking rack 2 according to the specific matching mode between the stacking rack 2 and the slide 36. In this application, in order to better install the opening and closing mechanism 35, the slide 36 penetrates the entire longitudinal beam 32. When the upper end of the stacking rack 2 is slidably installed in the slide 36, the upper end of the stacking rack 2 passes through the entire longitudinal beam 32, and can be connected to the opening and closing mechanism 35 installed on the longitudinal beam 32.

[0035] In one embodiment of the present application, the opening and closing mechanism 35 includes a servo motor 351 and an opening and closing screw 352. The servo motor 351 is installed at one end of the longitudinal beam 32. One end of the opening and closing screw 352 is connected to the output end of the servo motor 351. The opening and closing screw 352 is provided with threads with opposite rotation directions at both ends. The upper ends of the two groups of stacking racks 2 are respectively screwed with the threads of the corresponding group through screw nuts; the opening and closing screw 352 can control the support bodies 22 on the two groups of stacking racks 2 to move closer or farther away from each other in the length direction of the longitudinal beam 32. The servo motor 351 and the opening and closing screw 352 are both arranged in the slide groove 36, which is convenient for hiding components and saving space. The two groups of threads with opposite rotation directions on the opening and closing screw 352 can be used to achieve the two groups of stacking racks 2 to move closer or farther away when the opening and closing screw 352 is in the same direction. Moreover, due to the cooperation between the opening and closing screw 352 and the screw nut, the two groups of stacking racks 2 can be adjusted at any distance.

[0036] See also Figures 3 to 6In order to better install and fix the support body 22, the stacking rack 2 is provided with a sliding head 2a in the present application. The sliding head 2a is slidably installed on the longitudinal beam 32, and the lower end passes through the sliding groove 36 on the longitudinal beam 32 and is connected to the upper end of the support body 22. In the present application, a screw nut is also installed in the sliding head 2a, and is connected with the opening and closing screw 352.

[0037] Among them, the support body 22 is provided with detachable isolation pads 27 on the inner walls on both sides of the opening groove 24, and the isolation pads 27 are provided with movable holes 26 at the positions corresponding to the perforations 25; the support body 22 is provided with mounting grooves 223 on the inner walls on both sides of the opening groove 24 along the length direction, and the isolation pads 27 are installed on the support body 22 by cooperating with the mounting grooves 223 through the clamping strips. The isolation pads 27 can effectively prevent the support body 22 from scratching the copper busbar, and can also prevent the insulating layer covered by the copper busbar after scratching and polishing. Among them, the cross-section of the mounting groove 223 can be T-shaped or dovetail-shaped, and the shape of the clamping strip is correspondingly consistent with the shape of the mounting groove 223. Further, in order to facilitate material acquisition in this application, the isolation pads 27 are made of rubber material.

[0038] See also Figures 5 to 7 In order to better realize the automatic control of the action of the pin-driving block 28, a guide rail 221 is provided on the support body 22 along its length direction, and the pin-driving block 28 is slidably mounted on the guide rail 221. In order to better insert the movable latch 23 into the through hole 25 or pull it out from the through hole 25, a guide groove 29 is provided in the pin-driving block 28 in the present application along the guide direction of the guide rail 221, and the end of the movable latch 23 can slide in the guide groove 29, and the guide groove 29 is an inverted T-shaped groove structure. The guide groove 29 is provided with at least one low-position section 291 and at least one high-position section 292; the high-position section 292 is away from the opening groove 24 relative to the low-position section 291; the high-position section 292 and the low-position section 291 are smoothly connected by a slope section 293. In the present application, the distance difference between the high section 292 and the low section 291 from the opening slot 24 is used to control the distance between the end of the movable latch 23 and the opening slot 24, so that the worker only needs to drive the pin-driving block 28 to slide on the supporting body 22 to insert the movable latch 23 into the perforation 25 or pull it out from the perforation 25. The main purpose of designing the pin-driving block 28 in the present application is to better facilitate a worker to lift or put down the copper bar layer by layer, and at this time, the lowest isolation space 21 can be opened or closed by pulling out or inserting the movable latch 23 by sliding the pin-driving block 28. The opening or closing of the isolation space 21 does not require the worker to directly control the insertion or pulling out of the movable latch 23 to achieve.

[0039] See also Figure 6 and Figure 7, the high section 292 is located at the end of the guide slot 29 close to the opening of the opening slot 24, and the low section 291 is located at the end of the guide slot 29 close to the connection between the support body 22 and the lifting assembly 3. In the present application, when the worker slides the driving pin block 28 upward with one hand, the end of the movable latch 23 can only slide relative to the guide slot 29 because the movable latch 23 is restricted by the through hole 25; and the high section 292 is located at the lower end of the low section 291, and the low section 291 slides upward and gradually approaches the end of the movable latch 23 until the end of the movable latch 23 gradually slides relatively from the low section 291 to the high section 292, and the movable latch 23 can be pulled out from the through hole 25. On the contrary, when the movable latch 23 needs to be inserted into the through hole 25, it is only necessary to slide the pin drive block 28 downward, and use the end of the movable latch 23 to slide from the high section 292 to the low section 291. At this time, the distance difference between the movable latch 23 and the nearest side of the opening slot 24 gradually decreases until it is fully inserted into the other side of the opening slot 24, completing the closing of an isolation space 21. Before closing the isolation space 21, the operator can use the other hand to insert the copper row that needs to be lifted.

[0040] See also Figure 6 and Figure 7 In another embodiment of the present application, in order to better enable the end of the movable latch 23 to slide into or out of the low section 291, a smooth groove 294 is provided on the side of the outer end of the low section 291 close to the support body 22, and when the drive pin block 28 slides on the guide rail 221, the end of the movable latch 23 can slide into or out of the guide groove 29 through the groove 294. In order to achieve automation, a telescopic electric cylinder 222 is provided on the support body 22, and the output end of the telescopic electric cylinder 222 is connected to the drive pin block 28 to drive the drive pin block 28 to slide on the guide rail 221. Since each layer of copper bars may weigh ten or dozens of pounds, the weight of the entire layer of copper bars will be divided on the movable latch 23 at the lower end of the four isolation spaces 21. If the stressed movable latch 23 is pulled out manually by driving the drive pin block 28, it is obviously very laborious. Therefore, the present application uses the telescopic electric cylinder 222 to replace manual labor to reduce the labor intensity of workers driving the drive pin block 28.

[0041] The generator rotor winding coil cleaning and shaping support device of the present invention is designed with a lifting component 3, by which the height of the entire winding coil stack can be adjusted to adapt to winding coils of different stacking numbers, and also to workers of different heights, thereby improving convenience; the stacking rack 2 is adjustably mounted on the lifting component 3, so that the support system formed by the stacking rack 2 can adapt to winding coils of different diameters, thereby improving the adaptability of the support; and the movable latch 23 is used in conjunction with the open groove 24 to form an isolation space 21, which is convenient for stratifying each layer of copper bars in each group of winding coils, effectively reducing the impact of workers on other layers of copper bars during the process of polishing a certain layer of copper bars, and avoiding workers from accidentally damaging other layers of copper bars; in addition, the driving pin block 28 is used to force the movable latch 23 to be inserted into the through hole 25 or pulled out from the through hole 25, so that workers can fix the winding coils section by section on each stacking rack 2, thereby improving convenience of use, while reducing the manpower required for disassembling and assembling the winding coils, thereby reducing labor costs.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
