Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pole box assembly, and more specifically to an assembly tool for a magnetic pole box of a rotor of a semi-direct-drive wind turbine generator. Background Art

[0002] The mechanical transmission part of the semi-direct-drive wind turbine is similar to that of the doubly-fed unit, and the electrical transmission part is similar to that of the direct-drive unit. The generator is smaller than the direct-drive unit, and the overall cost is more advantageous than the direct-drive unit. It uses a low-speed gearbox and has higher reliability than the doubly-fed unit. It combines the advantages of direct-drive and doubly-fed units, and has both economy and reliability.

[0003] The rotor assembly of a semi-direct-drive wind turbine generator consists of a rotor bracket, a pole box, a tensioning mandrel, a pressure plate, an hexagon socket cylindrical screw and a hexagon nut; the pole box assembly is composed of 0.5mm thick silicon steel sheets stacked, pressed, bonded and welded into a pole box, and then the magnetic steel is installed to form a pole box. Three groups of T-slots are opened on the pole box assembly, and the pole boxes with the same polarity in each row are assembled and fixed into a whole through the tensioning mandrel and the pressure plates on both sides, and are radially fixed to the rotor bracket through the tensioning mandrel and the hexagon socket screws; the existing installation tools are not suitable for the pole box assembly of the above structure.

[0004] Because the pole box assembly has strong magnetism, it is very easy to be attracted to the tooling, rotor bracket and adjacent opposite-sex magnetic steel, causing collision damage to the pole box and personal injury. The pole boxes in the same row will have a large repulsive force due to the same polarity. If no corresponding measures are taken, there will be a large gap in the axial direction of the pole box assembly, causing the pole box assembly to be improperly installed. Utility Model Content

[0036] The utility model is described in detail below.

[0037] like Figure 1-Figure 6 As shown:

[0038] A semi-direct-drive wind turbine rotor magnetic pole box assembly tool, used in conjunction with a rotor bracket 100, comprises two groups of guide core rods 1 arranged axially along the rotor bracket 100 and installed on the outside of the rotor bracket 100, a guide pressure plate 2 arranged at the end of the rotor bracket 100 and located between the two groups of guide core rods 1, and a push drive mechanism 3 installed on the guide pressure plate 2 and used to control the magnetic pole box 200 to slide axially along the guide core rods 1; the push drive mechanism 3 is arranged on the outside of the rotor bracket 100 and located between the two groups of guide core rods 1;

[0039] This tooling is made of stainless steel and copper materials to avoid the strong magnetic influence of the pole box 200 assembly;

[0040] When the utility model is in use, the magnetic pole box 200 is installed on the outer side of the guide pressure plate 2 and the magnetic pole box 200 is sleeved on the outer sides of the two sets of guide core rods 1, and the magnetic pole box 200 is positioned by the guide pressure plate 2; the push drive mechanism 3 is installed on the guide pressure plate 2, and the magnetic pole box 200 is driven by the push drive mechanism 3 to move toward the rotor bracket 100 along the axial direction of the guide core rod 1, and the guide core rod 1 and the magnetic pole box 200 are temporarily fixed when reaching the specified position;

[0041] Repeat the above operation until all the pole boxes 200 at this position along the axial direction of the rotor support 100 are installed, replace the guide core rod 1 with a tensioning core rod, and then fix the pole box 200 and the tensioning core rod to complete the assembly.

[0042] In some possible implementations, in order to effectively define the assembly position pair of the pole box 200;

[0043] It also includes a limit plate 4 which is arranged on a side of the rotor support 100 away from the guide pressure plate 2 and is arranged parallel to the guide pressure plate 2;

[0044] The limiting plate 4 at the bottom of the rotor support 100 is used to support and limit the bottommost group of pole boxes 200 driven to this position by the push drive mechanism 3 to prevent them from sliding from the end of the guide core rod 1 away from the top of the rotor support 100.

[0045] In some possible implementations, in order to effectively achieve temporary fixation of the guide mandrel 1 and the pole box 200;

[0046] A plurality of groups of threaded holes are arranged on the guide mandrel 1, and the plurality of groups of threaded holes are evenly arranged along the axial direction thereof, and the axial direction of the threaded holes is arranged along the radial direction of the rotor support 100;

[0047] After the push-pushing driving mechanism 3 pushes a group of magnetic pole boxes 200 to the specified position, the group of magnetic pole boxes 200 is matched with the threaded holes on the guide core rod 1 by screws to achieve temporary fixation of the group of magnetic pole boxes 200; then the push-pushing driving mechanism 3 is controlled to move to the initial position to assemble the next group of magnetic pole boxes 200, and all the magnetic pole boxes 200 at this position are assembled;

[0048] In some possible implementations, in order to effectively realize the axial movement of the magnetic pole box 200 along the guide core rod 1 and avoid the situation where the magnetic pole box 200 cannot move due to strong magnetism;

[0049] The push drive mechanism 3 is mainly used to move the magnetic pole box 200 linearly along the axial direction of the rotor bracket 100; the electric push rod structure, oil cylinder or cylinder linear telescopic mechanism in the prior art can be used to realize the linear movement of the magnetic pole box 200;

[0050] The push driving mechanism 3 includes a push rod 31 which is arranged along the axial direction of the guide mandrel 1 and one end of which passes through the guide pressing plate 2, and a driving member for controlling the push rod 31 to move along the axial direction thereof;

[0051] One end of the push rod 31 passes through the guide pressure plate 2, and the other end thereof will be installed with the driving member; the push rod 31 is located between the two sets of guide core rods 1, and further, the distance between the axis of the push rod 31 and the two sets of guide core rods 1 is equal, so that when the magnetic pole box 200 is pushed, the magnetic pole box 200 is subjected to uniform force;

[0052] In some possible implementations, in order to prevent the push rod 31 from damaging the magnetic pole box 200 due to the concentrated force on the magnetic pole box 200 during the pushing process of the push rod 31;

[0053] The push driving mechanism 3 further includes a protection pad 32 connected to an end of the push rod 31 away from the driving member; the protection pad 32 is arranged parallel to the limit plate 4;

[0054] The center of the protective pad 32 is in the same straight line as the axis of the push rod 31. The arrangement of the protective pad 32 makes the contact area between the magnetic pole box 200 and the push drive mechanism 3 large, and there will be no concentrated force, so that the magnetic pole box 200 is evenly stressed. Specifically, the protective pad 32 is a square structure.

[0055] In some possible implementations, the push rod 31 is threadedly engaged with the guide pressure plate 2; one end of the push rod 31 is away from the protection pad 32; and the driving member is an electric wrench.

[0056] Before the pole box 200 is assembled, the protective pad 32 is installed on the top of the pole box 200 and abuts against it. One end of the push rod 31 passes through the guide pressure plate 2 and is connected to the protective pad 32. The push rod 31 is driven to rotate by an electric wrench, so that the push rod 31 moves toward the side close to the limit plate 4, thereby realizing the push of the pole box 200.

[0057] In some possible implementations, in order to effectively realize the installation with the push rod 31 by guiding the pressing plate 2, and to enable the push rod 31 to drive the magnetic pole box 200, and to facilitate the positioning of the magnetic pole box 200;

[0058] The guide pressure plate 2 includes a support plate 21 installed on the rotor bracket 100, a guide plate 22 installed on the support plate 21, and a top plate 23 connected to the guide plate 22 away from the support plate 21 and used for being installed on the driving mechanism; the support plate 21, the guide plate 22, and the top plate 23 form a Z-shaped structure; a gap is formed between the protective pad 32 and the guide plate 22.

[0059] In some possible implementations, in order to enable the guide plate 22 to effectively position the magnetic pole box 200, a positioning convex strip 24 is provided on the outer side of the guide plate 22 and is arranged parallel to the core guide rod and slidably cooperates with the magnetic pole box 200;

[0060] like Figure 2-Figure 4 As shown, the positioning convex strip 24 is arranged on the outer side of the guide plate 22, and a gap is formed between the outer side thereof and the protective pad 32; when the pole box 200 is installed, the T-slot 201 in the middle of one side of the pole box 200 close to the rotor bracket 100 will be inserted into the outer side of the positioning convex strip 24, and slide fit to achieve the positioning of the pole box 200, and the push drive mechanism 3 can realize the push of the pole box 200 through the sliding fit; after the pole box 200 is inserted into the outer side of the positioning convex strip 24, the pole box 200 is moved downward, and the T-slots 201 on both sides of the T-slot 201 will be inserted into the outer sides of the two groups of guide core rods 1, and then the pole box 200 can be pushed to the specified position through the push drive mechanism 3;

[0061] In some possible implementations, in order to facilitate operators to take and place the magnetic pole box 200;

[0062] like Figure 6 As shown, it also includes a pick-up and placement mechanism 5 for clamping the magnetic pole box 200 ; the pick-up and placement mechanism 5 includes a frame 51 provided with a clamping groove 511 , and a handle 52 provided on the outside of the frame 51 .

[0063] After the pole box 200 is located in the clamping groove 511 , the three groups of T-slots 201 will be located outside the frame 51 , so that the pole box 200 can be positioned and installed outside the guide plate 2 and installed in cooperation with the guide core rod 1 .

[0064] After all the pole boxes 200 at the rotor bracket 100 are installed, remove the guide pressure plate 2, the electric wrench and the push rod 31, and then insert the tensioning mandrel for assembling the pole box 200 into the middle T-slot 201. After tightening, remove the two sets of guide mandrels 1 and install the tensioning mandrel.
