Description

Technical Field

[0001] The utility model relates to the technical field of generator maintenance, in particular to a collector ring disassembly and assembly tool for a wind turbine generator. Background Art

[0002] Since wind turbines work outdoors all year round, the working conditions are relatively harsh, with large changes in temperature, humidity and load, as well as impact loads. Therefore, wind turbines require regular maintenance and servicing, especially collector rings, which need to be replaced frequently.

[0003] Traditional collector ring disassembly and assembly tools can often only remove the collector ring from the rotor shaft, and cannot effectively help with the installation of the collector ring. In addition, during disassembly, a screw is often used to connect the outward end face of the collector ring, and the collector ring is removed by pulling the screw, which causes the collector ring to be subjected to unilateral force and easily causes damage to the collector ring. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wind turbine generator collector ring disassembly and assembly tool in view of the above-mentioned technical deficiencies, which can facilitate the disassembly and installation of the collector ring body and avoid the problem that the collector ring body is easily damaged due to unilateral force during disassembly and assembly.

[0005] The technical solution adopted by the utility model is: to provide a wind turbine generator collector ring disassembly and assembly tool, comprising two corresponding parallel mounting plates, one on the left and one on the right; the mounting plates are connected by a plurality of support rods arranged along the left and right directions; a first through hole is opened in the middle of the mounting plate at the left end;

[0006] A disassembly plate is arranged in parallel to the left side of the left mounting plate; a sleeve shaft opening is opened vertically at the lower end of the disassembly plate; a limiting plate is arranged in parallel between the two mounting plates; the limiting plate and the disassembly plate are connected by a plurality of connecting rods arranged in the left and right directions; the connecting rod slides through the mounting plate at the left end; the support rod slides through the limiting plate; a first plug hole is opened on the right side of the support rod; a first screw hole is opened on the limiting plate; the first screw hole corresponds to the first plug hole;

[0007] An abutment plate is arranged parallel to and correspondingly between the mounting plate at the left end and the limiting plate; the abutment plate is slidably connected to the support rod; a base is arranged through the middle of the abutment plate; the base is rotatably connected to the abutment plate; a locking screw is coaxially fixed to the left end of the base; the locking screw is arranged along the left and right directions and passes through the first through hole correspondingly; a second plug hole is opened on the left side of the support rod; a screw seat is fixed on the abutment plate; the second plug hole corresponds to the screw seat;

[0008] A jack is fixed on the mounting plate at the right end; a second through hole is opened in the middle of the mounting plate at the right end; a connecting sleeve is fixed in the middle of the mounting plate at the right end; the connecting sleeve is correspondingly connected to the second through hole; the telescopic part of the jack passes through the second through hole and the connecting sleeve to the left; a third plug hole is opened on the connecting sleeve; a pin hole is penetrated at the left end of the telescopic part of the jack; the pin hole corresponds to the third plug hole.

[0009] To further optimize the technical solution, an end cap is coaxially fixed to the right end of the base of a wind turbine generator collector ring disassembly and assembly tool; and an external connection hole is radially opened on the side wall of the end cap.

[0010] To further optimize the technical solution, a wind turbine generator collector ring disassembly and assembly tool has buffer pads fixed to the left and right ends of the disassembly and assembly plate respectively.

[0011] To further optimize the technical solution, a guide sleeve corresponding to the collector ring body is coaxially fixed to the left end of a disassembly plate of a wind turbine generator collector ring disassembly tool.

[0012] The beneficial effects of the utility model are:

[0013] 1. Through the sleeve shaft opening on the disassembly plate, the disassembly plate can be conveniently inserted onto the rotor shaft from the outside, making it easier to apply external force to the collector ring body when disassembling and assembling it; the locking screw can be connected to the disassembly hole on the end face of the rotor shaft to achieve connection between the abutment plate and the rotor shaft.

[0014] A first plug hole is provided on the right side of the support rod, and a first screw hole is provided on the limiting plate. The first screw hole corresponds to the first plug hole, and the support rod and the limiting plate can be connected and fixed. When the telescopic part of the jack is extended to act on the abutment plate, due to the sliding connection between the abutment plate and the support rod, and the connection between the abutment plate and the rotor shaft, the jack will produce a reverse pushing effect, which pushes the installation plate on the right side in the reverse direction to drive the disassembly plate to move to the right, thereby pushing the collector ring body off the rotor shaft.

[0015] The disassembly plate can push down the collector ring body from the inner end face of the collector ring body, so as to avoid the problem that the outer end face of the collector ring body is subjected to unilateral force and is easily damaged.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 As shown, a wind turbine generator collector ring disassembly and assembly tool includes two corresponding parallel mounting plates 4, one on the left and one on the right; the mounting plates 4 are connected by multiple support rods 5 arranged along the left and right directions; a first through hole 6 is opened in the middle of the left mounting plate 4.

[0026] A disassembly plate 7 is arranged in parallel with the left side of the left-end mounting plate 4; a sleeve shaft opening 8 is opened vertically at the lower end of the disassembly plate 7; a limiting plate 9 is arranged in parallel with the two mounting plates 4; the limiting plate 9 and the disassembly plate 7 are connected by a plurality of connecting rods 10 arranged along the left and right directions; the connecting rod 10 slides through the left-end mounting plate 4; the support rod 5 slides through the limiting plate 9; a first plug hole 11 is opened on the right side of the support rod 5; a first screw hole 12 is opened on the limiting plate 9; the first screw hole 12 corresponds to the first plug hole 11.

[0027] like Figure 1-2As shown, an abutment plate 13 is arranged in parallel between the mounting plate 4 at the left end and the limiting plate 9; the abutment plate 13 is slidably connected to the support rod 5; a base 14 is arranged through the middle of the abutment plate 13; the base 14 is rotatably connected to the abutment plate 13; a locking screw 15 is coaxially fixed to the left end of the base 14; the locking screw 15 is arranged along the left and right directions and passes through the first through hole 6 correspondingly; a second insertion hole 16 is opened on the left side of the support rod 5; a screw seat 17 is fixed on the abutment plate 13; the second insertion hole 16 corresponds to the screw seat 17.

[0028] like Figure 3 , Figure 6 As shown, a jack 19 is fixed on the mounting plate 4 at the right end; a second through hole 20 is opened in the middle of the mounting plate 4 at the right end; a connecting sleeve 21 is fixed in the middle of the mounting plate 4 at the right end; the connecting sleeve 21 is correspondingly connected with the second through hole 20; the telescopic part of the jack 19 passes through the second through hole 20 and the connecting sleeve 21 to the left; a third plug hole 22 is opened on the connecting sleeve 21; a pin hole 23 is provided at the left end of the telescopic part of the jack 19; the pin hole 23 corresponds to the third plug hole 22.

[0029] When removing the collector ring body 3 from the rotor shaft 1, Figure 2-3 As shown, at this time, the first screw hole 12 is connected to the first plug hole 11 by the bolt 18 to realize the connection and fixation between the support rod 5 and the limiting plate 9, and then the disassembly plate 7 is sleeved on the rotor shaft 1 through the sleeve shaft opening 8, and the disassembly plate 7 is blocked on the end surface on the inner side of the collector ring body 3, and then the abutment plate 13 is slid along the support rod 5 to align the left end of the locking screw 15 with the disassembly hole 2 on the rotor shaft 1, and the locking screw 15 is connected and fixed to the disassembly hole 2 by the rotation connection between the base 14 and the abutment plate 13.

[0030] After completing the above connection process, when the telescopic part of the jack 19 is extended, it passes through the second through hole 20 and the connecting sleeve 21 on the right mounting plate 4, and acts on the abutment plate 13. Since the abutment plate 13 is connected to the rotor shaft 1, the jack 19 will produce a reverse pushing effect, pushing the mounting plate 4 on the right side in the reverse direction. Since the mounting plate 4 is fixed to the support rod 5, and the support rod 5 is fixed to the limiting plate 9 at this time, and the limiting plate 9 is connected to the disassembly plate 7 through the connecting rod 10, the final effect is to drive the disassembly plate 7 to move to the right, so that the collector ring body 3 can be gradually pushed and removed from the rotor shaft 1.

[0031] In addition, during the above disassembly process, the collector ring body 3 is pushed down from the inner end face of the collector ring body 3, so the problem of unilateral force on the outer end face of the collector ring body 3, which is easy to cause damage, is effectively avoided. When the collector ring body 3 is disassembled, the collector ring body 3 is effectively protected.

[0032] When installing the collector ring body 3 onto the rotor shaft 1, Figure 4-5As shown, at this time, the second socket 16 and the screw seat 17 are connected by the bolt 18, and the positioning pin 24 is inserted into the pin hole 23 and the third socket 22, so as to respectively realize the fixation of the abutment plate 13 and the support rod 5, and the telescopic part of the jack 19 and the limiting plate 9, and then the disassembly plate 7 is blocked at the outer end surface of the collector ring body 3 (the gap between the connecting rods 10 is large enough for the collector ring body 3 to enter), so that the locking screw 15 passes through the middle of the collector ring body 3 and is connected and fixed to the disassembly hole 2 of the rotor shaft 1.

[0033] After completing the above connection process, due to the fixation of the abutment plate 13 and the support rod 5, the mounting plate 4 is fixed at this time. When the telescopic part of the jack 19 is extended, the limiting plate 9 and the support rod 5 slide, and the connecting rod 10 slides through the mounting plate 4 at the left end, so that the limiting plate 9 will be directly pushed to the left. The disassembly plate 7 connected to the limiting plate 9 through the connecting rod 10 can be moved to the left, so that the collector ring body 3 is gradually inserted into the rotor shaft 1.

[0034] In summary, it is obvious that the technical solution can realize the switching of the removal or installation function of the collector ring body 3 by only changing the connection relationship between some components, making the function comprehensive.

[0035] An end cap 25 is coaxially fixed to the right end of the base 14; an external plug hole 26 is radially opened on the side wall of the end cap 25. An external extension rod can be inserted through the external plug hole 26, making the operation more convenient and labor-saving when the locking screw 15 is connected to the rotor shaft 1.

[0036] Buffer pads 27 are respectively fixed to the left and right ends of the disassembly and assembly plate 7. The buffer pads 27 can protect the end face of the collector ring body 3 during the disassembly or installation process.

[0037] A guide sleeve 28 corresponding to the collector ring body 3 is coaxially fixed to the left end of the disassembly plate 7. The guide sleeve 28 can be sleeved on the outside of the collector ring body 3, and when the collector ring body 3 and the rotor shaft 1 are installed, it is convenient to make the two more accurately aligned.
