[0074] like Figures 1 to 5As shown, this embodiment provides a replacement system 1 for replacing or repairing a device to be repaired in a wind turbine generator set. The device to be repaired includes a device 2 mounted on a frame 3 of the wind turbine generator set. The frame 3 is mounted atop a tower 5 of the wind turbine generator set, and the device 2 is located on an outer side of the tower 5. The replacement system 1 includes a hoisting device 10, a hoisting device 20, a first support frame 40, and a second support frame 50.

[0075] The hoisting device 10 is detachably connected to the frame 3 and is arranged corresponding to the position of the equipment to be repaired 2. The hoisting device 10 includes a hoisting component 11 for connecting to the equipment to be repaired 2. The hoisting component 11 is connected to the hoisting device 20 through a rope 30.

[0076] The first support frame 40 and the equipment to be repaired 2 are arranged on the same outer side of the tower 5. The first support frame 40 is used to place the equipment to be repaired 2. However, the first support frame 40 can also be used to place equipment to be replaced (i.e., equipment that replaces the equipment to be repaired 2); alternatively, the first support frame 40 can be used to place both the equipment to be repaired 2 and the equipment to be replaced; this can be adjusted as needed. The first support frame 40 can be located at the bottom of the tower 5 to facilitate the lifting of the equipment to be repaired 2 and / or the equipment to be replaced.

The equipment to be repaired 2 may include other equipment, such as a generator, a reducer, and other working equipment installed on the rack 3. Similarly, the equipment to be replaced may also include a transformer, but is not limited to this. The equipment to be replaced may include other equipment, such as a generator, a reducer, and other working equipment installed on the rack 3.

[0080] Furthermore, the first support frame 40 is detachably connected to the outer wall of the bottom of the tower 5. Thus, by detachably connecting the first support frame 40 to the outer wall of the bottom of the tower 5, the first support frame 40 can be installed and fixed by taking advantage of the height of the bottom of the tower 5 without the need for a separate mounting base, thereby achieving the beneficial technical effect of simplifying the structure of the entire replacement system 1. However, this is not limiting. In other embodiments, the first support frame 40 can also be installed on the outer side of the bottom of the tower 5 via a mounting base or directly.

[0081] Specifically, replacement system 1 also includes a first mounting assembly, which includes a first mounting member and a second mounting member that cooperate with each other. The first mounting member is mounted on first support frame 40, and the second mounting member is mounted on the outer wall of the bottom of tower 5. Thus, the provision of the first mounting assembly facilitates the removal and installation of first support frame 40 on the outer wall of the bottom of tower 5. The first mounting member is a mounting joint, and the second mounting member is a corresponding mounting interface; alternatively, the first mounting member is a mounting interface, and the second mounting member is a mounting joint.

[0082] The second support frame 50 is detachably connected to the outer wall of the bottom of the tower 5. By detachably connecting the second support frame 50 to the outer wall of the bottom of the tower 5, the second support frame 50 can be installed and fixed by taking advantage of the height of the bottom of the tower 5 without the need for a separate mounting base, thereby achieving the beneficial technical effect of simplifying the structure of the entire replacement system 1. However, the present invention is not limited to this. In other embodiments, the second support frame 50 can also be installed on the outer side of the bottom of the tower 5 via a mounting base or directly.

[0083] Specifically, replacement system 1 also includes a second mounting assembly, which includes a third mounting member and a fourth mounting member that cooperate with each other. The third mounting member is mounted on second support frame 50, and the fourth mounting member is mounted on the outer wall of the bottom of tower 5. Thus, the provision of the second mounting assembly facilitates the removal and installation of second support frame 50 on the outer wall of the bottom of tower 5. The third mounting member is a mounting joint, and the corresponding fourth mounting member is a mounting interface. Alternatively, the third mounting member is a mounting interface, and the corresponding fourth mounting member is a mounting joint.

[0084] It should be noted that in the prior art, since large specialized equipment and wind turbine components are placed on the tower base, high load-bearing capacity is required of the tower base. However, in this embodiment, since only the first support frame 40 and the second support frame 50 are mounted on the outer wall of the bottom of the tower 5, high load-bearing capacity requirements are not required for the tower base, thereby significantly reducing the tower base manufacturing cost.

[0085] In this embodiment, the frame 3 includes a front frame 32 and a rear frame 31 connected to each other. The equipment to be repaired 2 is installed on the rear frame 31 of the wind turbine generator set, and the front frame 32 is fixed to the top of the tower 5 of the wind turbine generator set.

[0086] The rear frame 31 includes two first frames 311 arranged along the length direction L of the frame 3, and at least three second frames 312 arranged along the width direction W of the frame 3. The two ends of the at least three second frames 312 are respectively fixed to the two first frames 311, and the equipment 2 to be repaired is installed in the space formed by two adjacent second frames 312 and the two first frames 311.

[0087] The lifting device 10 further includes a hanger 12, the ends of which are detachably mounted on two second frames 312 adjacent to the equipment 2 to be repaired, and the lifting component 11 is mounted on the hanger 12. Thus, by detachably mounting the ends of the hanger 12 of the lifting device 10 on the two second frames 312 adjacent to the equipment 2 to be repaired, a lifting fulcrum is provided for the lifting component 11, thereby completing the lifting work of the equipment 2 to be repaired.

[0088] Preferably, the hanging device 10 further includes an auxiliary bracket 13, one end of the auxiliary bracket 13 is connected to the hanger 12, and the other end is detachably connected to the second frame 312 not connected to the hanger 12.

The first diverting pulley assembly 60 includes a first bracket 61, a first pulley 62 mounted on the first bracket 61 and arranged in a vertical direction H, and a second pulley 63 mounted in a horizontal direction. The first bracket 61 is detachably connected to the front frame 32, the second pulley 63 is located near the equipment 2 to be repaired, and the first pulley 62 is located away from the equipment 2 to be repaired. The rope 30 is sequentially threaded through the hoisting device 20, the first pulley 62, and the second pulley 63. Thus, by providing the first diverting pulley assembly 60, the direction of the rope 30 can be adjusted, thereby enabling the hoisting device 20, located on one outer side of the tower 5, to hoist the equipment 2 to be repaired, located on the other outer side of the tower 5. It should be noted that, in the embodiment of the present application, after the replacement system 1 is installed, the vertical direction H is parallel to the axial direction of the tower 5 ; the horizontal direction is perpendicular to the axial direction of the tower 5 .

[0090] The replacement system 1 also includes a second diverting pulley assembly 70, which is detachably connected to the rear frame 31 and is adjacent to an outer side of the hoisting device 10 along the length direction L of the frame 3.

The rope 30 is sequentially threaded through the winch device 20, the first pulley 62, the second pulley 63, the third pulley 72, the fourth pulley 73, and the hoisting component 11. In this way, by setting the second steering pulley assembly 70, the direction of the rope 30 is adjusted, so that the winch device 20 set on one outside of the tower 5 can lift the equipment to be repaired 2 set on the other outside of the tower 5, and the rope 30 can be adjusted from the outside of the tower 5 to the position corresponding to the lifting component 11, so that the equipment to be repaired 2 can be lifted from the positive direction to avoid loss of force.

[0091] Specifically, the hoisting device 20 includes a winch or a hoisting machine, but is not limited thereto. In other embodiments, the hoisting device 20 may also include other devices that can provide pulling force.
