[0036] The utility model discloses a main bearing seat of a wind turbine generator set, which includes a barrel seat 10 and a locking assembly 30. One side of the barrel seat 10 is provided with a barrel mouth 11, and the edge of the barrel mouth 11 is provided with a mounting platform 20; the locking assembly 30 is detachably connected to the mounting platform 20; wherein the locking assembly 30 is provided with a locking portion, the locking portion protrudes from the outside of the barrel mouth 11, and the locking portion extends toward one side of the barrel seat 10, and the locking portion is used to be clamped with the edge of the external main shaft 50.

[0037] Under normal maintenance conditions, the high-speed shaft can be locked, which is very convenient. However, under some conditions, such as when replacing the gearbox, it can only be done by locking the low-speed shaft, that is, directly locking the main shaft 50 on the wind turbine generator set, thereby indirectly braking the wind wheel and blades connected to the main shaft 50.

[0038] In one embodiment, please refer to Figure 1 The cartridge seat 10 and the main shaft 50 are both cylindrical in structure. The cartridge seat 10 has a cartridge opening 11 on the side facing the main shaft 50. The cartridge opening 11 may be a hollow structure, an open structure, a closed structure, or the like.

[0039] The cartridge seat 10 and the main shaft 50 are arranged in concentric circles. In addition, the cartridge seat 10 may also adopt a polyhedral column structure, for example. It is only necessary to ensure that after the locking assembly 30 is installed on the mounting platform 20, the locking assembly 30 can contact and connect with the main shaft 50 to play a locking role.

[0040] Before locking the main shaft 50 , the blades of the wind turbine generator set are braked to stop, so as to prevent the rotating main shaft 50 from causing physical harm to the operator.

[0041] An outwardly protruding mounting platform 20 is installed on the outer wall edge of the barrel mouth 11, and the locking assembly 30 is installed on the mounting platform 20 in a detachable manner. When low-speed shaft locking is required, the locking assembly 30 can be installed on the mounting platform 20, and the locking assembly 30 can be removed from the mounting platform 20 after maintenance is completed.

[0042] It can be understood that there is a gap between the cartridge seat 10 and the spindle 50. In order to ensure that the locking assembly 30 can be directly connected to the spindle 50, the mounting platform 20 and / or the locking assembly 30 protrude from the outside of the cartridge mouth 11. The outside of the cartridge mouth 11 refers to the side of the cartridge seat 10 facing the spindle 50. Figure 1 In this embodiment, the edge of the mounting platform 20 is connected to the edge side wall of the barrel mouth 11, and the end portion extends toward the side of the main shaft 50, so that after the locking assembly 30 is installed on the mounting platform 20, it protrudes from the outside of the barrel mouth 11.

[0043] The locking assembly 30 can be connected to the main shaft 50 by means of, for example, a stud bolt, so as to lock the main shaft 50 .

[0044] The technical solution of the utility model is to install the locking assembly 30 on the mounting platform 20 in a detachable connection manner when the main shaft 50 needs to be fixed. The mounting platform 20 is installed on the edge of the barrel mouth 11 of the barrel seat 10 to avoid occupying the installation space of the barrel seat 10. The locking assembly 30 is directly connected to the main shaft 50 for fixing, driving the relevant structure for locking on the main shaft 50, avoiding the dangerous situation that the wind wheel is still rotating during maintenance. In addition, the locking assembly 30 is easily connected to the main shaft 50, which improves the locking efficiency.

[0045] In one embodiment, the mounting platform 20 includes a flange rib 22 and a mounting plate 21, one end of the flange rib 22 is arranged on the edge of the barrel mouth 11, and the other end of the flange rib 22 extends along the radial direction of the barrel seat 10; one end of the mounting plate 21 is connected to the flange rib 22, and the other end extends along the axial direction of the barrel seat 10 to form a boss for mounting the locking assembly 30.

[0046] To further improve stability, there are two mounting platforms 20. Figure 1 The two mounting plates 21 are respectively on the left and right sides of the cartridge seat 10, or on any two opposite sides.

[0047] The plate surface of the mounting plate 21 is used to place or install the locking assembly 30, and the plate surface is parallel to the axial direction of the cartridge seat 10. The flange rib plate 22 extends along the circumference of the side wall of the cartridge seat 10 and extends to connect with the mounting plate 21 to increase the contact area between the mounting plate 21 and the cartridge seat 10, improve the connection strength of the mounting plate 21, and ensure stability during use.

[0048] In other cases, the number of the mounting platforms 20 may also be multiple, and the multiple mounting platforms 20 are evenly spaced along the edge of the barrel mouth 11 to cope with different scene requirements.

[0054] The function of the reinforcing rib plate 23 is to increase the contact area between the mounting plate 21 and the flange rib plate 22 , so as to increase the connection strength between the mounting plate 21 and the flange rib plate 22 and improve the stability during the process of locking the main shaft 50 .

[0055] The thickness of the reinforcing rib plate 23 can be adjusted according to the specific dimensions of the mounting plate 21 and the flange rib plate 22 to meet the locking condition requirements.

[0056] In one embodiment, the locking assembly 30 includes a fixing plate 31 and a connecting member 32, and the fixing plate 31 is detachably connected to the mounting table 20; the connecting member 32 is arranged on the fixing plate 31, and one end of the fixing plate 31 extends toward one side of the cartridge seat 10 to form the locking portion, and a through hole is provided on the locking portion, and the through hole corresponds to the position of the locking hole on the external main shaft 50.

[0058] The bottom of the connecting member 32 is connected to the fixing plate 31 , and the side wall of the connecting member 32 extends toward one side of the main shaft 50 . The extended portion is connected to the edge of the main shaft 50 through a stud, thereby locking the main shaft 50 .

[0059] Specifically, the locking part is provided with a through hole, and a plurality of locking holes are correspondingly provided on the edge of the main shaft 50.

The side of the wind wheel is provided with a threaded hole, and the position of the threaded hole corresponds to the position of the locking hole of the main shaft 50. A washer nut and a stud are added at the position of the locking hole to achieve connection.

[0060] When braking, remove the original stud, adjust the through hole on the locking part to correspond to the locking hole, replace a longer stud and pass it through the through hole, locking hole and threaded hole in sequence, add a nut to the through hole side to tighten, and brake the main shaft and the wind wheel through the friction plate generated by clamping. Multiple through holes, locking holes and threaded holes are set along the edge so that the connector 32 can be connected to any position on the main shaft 50 to achieve locking, and the operator does not need to rotate to a specific angle for locking, which improves the locking efficiency and reduces the difficulty of operation.
