In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application.

[0056] In the description of this application, it should be understood that the terms "counterclockwise", "clockwise", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0057] Figure 1 A schematic diagram of the scenario for disassembling and assembling the bearing baffle of a wind turbine provided in this application is as follows Figure 1 As shown, a generator bearing 11 and a bearing baffle 12 are installed on a generator shaft 10. When a fault occurs in the generator set bearing, the generator bearing 11 needs to be replaced. However, during the replacement process, it is difficult to disassemble and assemble the bearing baffle 12 from the generator shaft 10, and multiple people are required to cooperate for disassembly. Moreover, during disassembly, personnel also need to support the generator shaft 10, which is likely to cause injury to personnel.

[0058] Combined with the above scenario, it can be seen that in the prior art, there are technical problems such as difficult disassembly, time-consuming and laborious, and easy to cause injury to personnel when disassembling the bearing baffle on the generator set shaft.

[0059] A disassembly and assembly device for a bearing baffle of a wind turbine provided in this application, by means of a support component abutting against the generator shaft, after connecting the disassembly and assembly component and the bearing baffle, and adjusting the telescopic component connected between the support component and the disassembly and assembly component to disassemble the bearing baffle, solves the technical problems of difficult disassembly of the bearing baffle, time-consuming and laborious, and easy to cause injury to personnel.

[0060] The following will specifically describe the technical solution of this application and how the technical solution of this application solves the above technical problems in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0061] Figure 2 A structural schematic of a disassembly and assembly device for a bearing baffle of a wind turbine provided in this application Figure 1 ; As Figure 2 shown, the disassembly and assembly device includes: a disassembly and assembly component 100, a support component 200, and a telescopic component 300; the support component 200 is arranged on the side close to the generator shaft 10 and is detachably connected to the generator shaft 10; the disassembly and assembly component 100 includes a tooling plate 110 and a plurality of screw rods 120; one ends of the plurality of screw rods 120 are respectively evenly and detachably connected to the tooling plate 110, and the plurality of screw rods 120 are evenly arranged around the outside of the generator shaft 10; the other ends of the plurality of screw rods 120 are detachably connected to the bearing baffle 12.

[0062] The disassembly and assembly component 100 is used to be detachably connected to the bearing baffle 12 by means of bolts, pins or clamping, etc., and disassemble the bearing baffle 12 from the generator shaft 10. For example, after being detachably connected to the bearing baffle 12, the bearing baffle 12 is pulled off from the generator shaft 1.

[0063] The support assembly 200 is used to interfere with the generator shaft 10 when the disassembly assembly 100 removes the bearing baffle 12 from the generator shaft 10, providing a fulcrum for the disassembly assembly 100, so that the disassembly assembly 100 can move away from the generator shaft 10, thereby pulling the bearing baffle 12 away from the generator shaft 10.

[0064] The telescopic assembly 300 is used to detachably connect the disassembly assembly 100 and the support assembly 200 respectively when the disassembly assembly 100 and the bearing baffle 12 are detachably connected and the support assembly 200 and the generator shaft 12 are in conflict, and to control the disassembly assembly 100 to move freely relative to the generator shaft 12, so that the disassembly assembly 100 can remove the bearing baffle 12.

[0065] The two ends of the telescopic assembly 300 are connected to the support assembly 200 and the tooling plate 110 respectively; the telescopic assembly 300 can drive the tooling plate 110 to move freely in the horizontal direction relative to the support assembly 200.

[0066] The telescopic assembly 300 is detachably connected to the support assembly 200 and the tooling plate 110, respectively. The support assembly 200 is in contact with the generator shaft 10, and the tooling plate 110 and the bearing baffle 12 are detachably connected to the two ends of multiple screws 120, respectively. The telescopic assembly 300 controls the movement of the tooling plate 110 to remove the bearing baffle 12 from the generator shaft 10; when the bearing baffle 12 is removed, the telescopic assembly 300 is in a retracted state, causing the support assembly 200 to contact the generator shaft 10, and the disassembly assembly 100 is connected to the bearing baffle 12, so that the retracted assembly 300 is extended by hydraulic or elastic principles, driving the disassembly assembly 100 to move away from the generator shaft 10, and pulling out the bearing baffle 12.

[0067] The support assembly 200 is arranged on a side close to the generator shaft 10, and is detachably connected to the generator shaft 10 by means of clamping, bolts, etc., or is in conflict with the generator shaft 10; a plurality of screws 120 are detachably connected to the tooling plate 110 on the disassembly assembly 100, and the plurality of screws 120 are respectively and evenly connected to the tooling plate 110. When one end of the plurality of screws 120 on the disassembly assembly 100 is detachably connected to the bearing baffle 12, the plurality of screws 120 are evenly surrounded on the outside of the generator shaft 10.

[0068] An embodiment of the present application provides a disassembly and assembly device for a bearing baffle of a wind turbine generator, which includes a disassembly and assembly component, a support component, and a telescopic component; the support component is arranged close to the generator shaft side and is detachably connected to the generator shaft; the disassembly and assembly component includes a tooling plate and a plurality of screw rods; one ends of the plurality of screw rods are respectively evenly and detachably connected to the tooling plate, and the plurality of screw rods are evenly arranged around the outside of the generator shaft; the other ends of the plurality of screw rods are detachably connected to the bearing baffle; both ends of the telescopic component are respectively connected to the support component and the working plate; the telescopic component can drive the tooling plate to move freely relative to the support component in the horizontal direction; the disassembly and assembly device provided by the embodiment of the present application can easily and simply disassemble the bearing baffle from the generator shaft, saving manpower and time, and does not require personnel to support it, avoiding personal injuries, etc.

[0069] Further, on the basis of the above embodiment, a detailed description of the tooling plate is as follows Figure 3 As shown, a plurality of threaded through holes 140 matching the plurality of screw rods 120 are arranged on the tooling plate 110; each screw rod 120 passes through the tooling plate 110 through the threaded through hole 140 and is connected to the screw cap 130; each screw rod 120 moves on the working plate 110 through the thread to drive the bearing baffle 12 away from the generator bearing 11.

[0070] The tooling plate 110 can be circular, square, etc. The tooling plate 110 faces the generator bearing 10. A plurality of threaded through holes 140 matching the plurality of screw rods 120 are arranged on the tooling plate 110, so that each screw rod 120 passes through any corresponding threaded through hole 140 and is connected to the bearing baffle 12.

[0071] In order to fix the tooling plate 110 and the plurality of screw rods 120, so that when the tooling plate 110 moves relative to the generator shaft 10, it drives the plurality of screw rods 120 to move and pull off the bearing baffle 12. When each screw rod 120 passes through the tooling plate 110, a screw cap 130 is connected to each screw rod 120.

[0072] Furthermore, as Figure 2 shown, the thicknesses of the plurality of screw rods 120 are different. The screw rods 120 with the first diameter and the screw rods 120 with the second diameter are arranged at intervals, and the first diameter is greater than the second diameter.

[0073] The plurality of screw rods 120 have the same length, and the length of the plurality of screw rods 120 is greater than the distance from the tooling plate 110 to the bearing baffle 12; the plurality of screw rods 120 have different diameters. Among them, the screw rods 120 with the first diameter and the screw rods 120 with the second diameter can be fixedly connected by welding, bonding, etc., or detachably connected by bolts, pins, etc.; the screw rods 120 with the first diameter can be connected to the bearing baffle 12, and the screw rods 120 with the second diameter can be connected to the tooling plate 110.

[0074] Furthermore, asFigure 3 As shown, the support assembly 200 includes a support circular plate 210 and a plurality of support rods 220; the plurality of support rods 220 are arranged in a ring at uniform intervals, and one end of each of the plurality of support rods 220 is fixedly connected to the support circular plate 210; the other ends of the plurality of support rods 220 are detachably connected to the generator shaft 10; the plurality of support rods 220 and the plurality of screw rods 120 are located on the same side.

[0075] Since one end of the generator shaft 10 has a rotor lead wire 13, in order to protect the rotor lead wire 13, a plurality of support rods 220 are fixedly arranged at intervals on the support circular plate 210. There are interval gaps between the plurality of support rods 220 and between the support circular plate 210 and the generator shaft 10, avoiding damage to the rotor lead wire 13.

[0076] The diameter dimension of the support circular plate 210 is set to be similar to that of the generator shaft 10. The plurality of support rods 220 are evenly and annularly arranged at intervals at the edge position of the support circular plate 210, and the plurality of support rods 220 are perpendicular to the support circular plate 210. The support circular plate 210 and the tooling plate 110 are arranged on the same side of the generator shaft 10 and are both located on the opposite side of the bearing baffle 12.

[0077] Further, as Figure 5 shown, a plurality of connecting circular grooves 230 matching the plurality of support rods 220 are provided on the support circular plate 210; each support rod 220 is detachably connected to each corresponding connecting circular groove 230.

[0078] A plurality of connecting circular grooves 230 adapted to the plurality of support rods 220 are provided on the support circular plate 210. Each support rod 220 can be fixedly connected to any corresponding connecting circular groove 230 by welding, bonding, etc.; or each support rod 220 can be detachably connected to any corresponding connecting circular groove 230 by bolts, snap connections, etc. For example, external screw threads are provided at the connection end of the support rod 220 and the support circular plate 210, and internal screw threads adapted thereto are provided on the connecting circular groove 230 to achieve the detachable connection between the support rod 22o and the connecting circular groove 230.

[0079] Further, as Figure 2 shown, the telescopic assembly 300 includes a telescopic member 310 and a telescopic sleeve 320; the telescopic sleeve 320 is sleeved on the telescopic member 310, and the telescopic member 310 can move freely in the telescopic sleeve 320; the telescopic sleeve 320 is fixedly connected or detachably connected to the tooling plate 110, and the telescopic member 310 is detachably connected to the support circular plate 210; the tooling plate 110 is driven by the telescopic assembly 300 to move freely in the horizontal direction relative to the support circular plate 210.

[0080] The telescopic member 310 on the telescopic assembly 300 is sleeved in the telescopic kit 320. The telescopic member 310 can move telescopically in the telescopic kit 320 through hydraulic pressure, elastic devices, etc. The telescopic assembly 300 is arranged between the tooling plate 110 and the support circular plate 210. The telescopic kit 320 is fixedly connected or detachably connected to the tooling plate 110, and the telescopic member 310 is detachably connected to the support circular plate 210.

[0081] Under the action of the hydraulic principle or the elastic principle, when the telescopic member 310 moves telescopically in the telescopic kit 320, the telescopic assembly 300 drives the tooling plate 110 to move freely in the horizontal direction relative to the support circular plate 210, and the multiple screws 120 on the tooling plate 110 move to remove the bearing baffle 12.

[0082] Furthermore, as Figure 3 shown, the number of the screws 120 is greater than the number of the support rods 220.

[0083] To make the tension received by the bearing baffle 12 uniform and easy to remove it, the number of the screws 120 is set to be greater than the number of the support rods 220. The support rods 220 play a role in supporting the disassembly and assembly device and providing a stable fulcrum.

[0084] Furthermore, as Figure 3 shown, the distance from each screw 120 to the center of the tooling plate 110 is greater than the radius of the support circular plate 210; the distance from each support rod 220 to the center of the support circular plate 210 is greater than the coil dimension of the rotor lead 13.

[0085] To enable the multiple screws 120 to pass through the tooling plate 110 and then be sleeved onto the generator shaft 10, the distance from each screw to the tooling plate 110 is greater than the radius of the support circular plate 210 and also greater than the radius of the generator shaft 10.

[0086] To protect the rotor lead 13, the distance from the support rod 220 to the center of the support circular plate 210 is set to be greater than the coil dimension of the rotor lead 13.

[0087] Furthermore, as Figure 4 shown, the distance from each screw 120 to the center of the tooling plate 110 is less than or equal to the radius of the bearing baffle 12.

[0088] To sleeve the multiple screws 120 onto the generator shaft 10 and connect them to the bearing baffle 12 on the generator shaft 10, the distance from each screw 120 to the center of the tooling plate 110 is less than or equal to the radius of the bearing baffle 12.

[0089] Furthermore, as Figure 4 shown, the multiple screws 120 and the multiple support rods 220 are respectively parallel to the generator shaft 10.

[0090] To stably support the support rod 220 and enable the screw 120 to easily disassemble the bearing baffle 12, a plurality of screws 120 and a plurality of support rods 220 are both arranged parallel to the generator shaft 10.
