Description

Technical Field

[0001] The invention relates to the technical field of wind power casting transportation, and in particular to a wind power casting transportation tooling and a use method thereof. Background Art

[0002] When transporting the wind turbine casting hub, transport tooling is used to fix the wind turbine casting hub. The purpose is to prevent the wind turbine casting hub from falling due to bad and bumpy transportation conditions during transportation, thereby injuring passers-by and ensuring the smooth transportation of the wind turbine casting hub.

[0003] The prior art provides a large-scale wind turbine casting recyclable transport tooling (publication number CN219970433U). After the wind turbine casting hub is hoisted, it is placed in the profiling groove, which is convenient for the precise alignment and positioning of the wind turbine casting hub, has good matching degree, and can effectively ensure the stability of the wind turbine casting hub after placement; after the wind turbine casting hub is placed in the profiling groove. The device is clamped by a profiling fastener, and the third blade flange surface is clamped by a second fastener. Regardless of the first fastener, the profiling fastener, and the second fastener, they all limit the clamping of the wind turbine casting hub from the outside. Compared with the clamping and clamping of the clamping block in the background technology, it has good stability and avoids the trouble of repeated disassembly of the clamping parts.

During the start-up of the transport vehicle, the wind turbine casting hub will exert a large pressure on the arc-shaped profiling clamp due to its own inertia, and the second fastener and the wind turbine casting hub will also generate a large pulling force, which makes the transport tooling unable to be used for a long time.

[0044] The invention provides Figure 1-Figure 10As shown, a wind power casting transport tool comprises a wind turbine casting hub 1 and a base 2, the wind turbine casting hub 1 is placed on the surface of the base 2, and the base 2 is provided with a vertical limiting mechanism 3, a side support mechanism 4, a side limiting mechanism 5 and a bottom support mechanism 7, the vertical limiting mechanism 3 is vertically arranged on the surface of the base 2, and the vertical limiting mechanism 3 penetrates the surface of the wind turbine casting hub 1 and vertically supports the inside of the wind turbine casting hub 1, the side support mechanism 4 comprises an arc-shaped support plate 41, and the arc-shaped support plate 41 is movable The movable plate 51 is movably arranged on one side of the base 2 and is attached to the surface of the wind turbine casting hub 1. The side limiting mechanism 5 includes a movable plate 51, which is vertically slidably arranged on the other side of the base 2. The movable plate 51 is connected with the arc support plate 41 through the first driving mechanism 6 to drive the arc support plate 41 to move simultaneously with the movable plate 51. The bottom supporting mechanism 7 includes an arc support seat 71, which is connected with the arc support plate 41 through the second driving mechanism 8 to drive the arc support seat 71 to move simultaneously with the movable plate 51.

[0045] See also Figure 1 , Figure 2 and Figure 3 The wind turbine casting hub 1 is placed on the base 2, and the vertical limiting mechanism 3 vertically supports and fixes the wind turbine casting hub 1 from the inside. The movable plate 51 moves toward the direction close to the wind turbine casting hub 1 under the drive of the first driving mechanism 6. The first driving mechanism 6 drives the arc support plate 41 to rotate, and the arc support plate 41 and the movable plate 51 respectively limit the wind turbine casting hub 1 laterally from both sides of the wind turbine casting hub 1. The arc support plate 41 drives the arc support seat 71 to move upward through the second driving mechanism 8 to achieve stable support for the wind turbine casting hub 1.

[0046] Specifically, the vertical limiting mechanism 3 includes a motor 31, a main shaft 32, a sleeve 33, a threaded rod 34 and a support rod 35. The motor 31 is fixed to the bottom of the base 2, the main shaft 32 is rotatably set at the top of the base 2 and is connected to the output end of the motor 31, the sleeve 33 is fixed to the surface of the base 2 and is concentrically set with the main shaft 32, the top of the main shaft 32 is rotatably set on the top inner wall of the sleeve 33, the threaded rod 34 is vertically rotatably set on the surface of the sleeve 33, one end of the threaded rod 34 is connected to the main shaft 32 through a transmission structure, the support rod 35 is threadedly connected to the threaded rod 34, and the surface of the support rod 35 is in contact with the inner wall of the wind turbine casting hub 1, the transmission structure includes a first bevel gear 36 fixed on the main shaft 32, and a second bevel gear 37 fixed at one end of the threaded rod 34, and the second bevel gear 37 is meshed with the first bevel gear 36.

[0047] See also Figure 6-Figure 9The motor 31 can drive the main shaft 32 to rotate under the base 2. When the main shaft 32 rotates, it can drive the first bevel gear 36 to rotate synchronously, and the first bevel gear 36 can drive the threaded rod 34 to rotate under the drive of the second bevel gear 37. At this time, the two threaded rods 34 on the same direction of the surface of the sleeve 33 can simultaneously drive the same support rod 35 to move horizontally, and the three support rods 35 can move with the same stroke on the surface of the sleeve 33 until the three support rods 35 all hit the inner wall of the wind turbine casting hub 1 to achieve vertical limitation of the wind turbine casting hub 1.

[0048] It should be noted that, during the above process, the wind turbine casting hub 1 is still in a hoisting state, and the three support rods 35 can continuously adjust the position of the wind turbine casting hub 1 until the wind turbine casting hub 1 is concentric with the main shaft 32 or the sleeve 33, and during this process, the staff manually adjusts the angle of the wind turbine casting hub 1 to facilitate the side support mechanism 4 and the side limit mechanism 5 to limit it.

[0049] Specifically, the side support mechanism 4 also includes a support arm 42, a receiving groove 43 and a first rotating shaft 44, the first rotating shaft 44 is rotatably set on the inner wall of the base 2, the receiving groove 43 is set on the surface of the base 2, one end of the support arm 42 is fixed to the surface of the arc-shaped support plate 41, and the other end of the support arm 42 passes through the receiving groove 43 and is fixed to the surface of the first rotating shaft 44.

[0050] See also Figure 1 , Figure 2 , Figure 3 and Fig. 9 In the initial state, the support arm 42 is in an inclined state. At this time, the support arm 42 drives the arc-shaped support plate 41 away from the wind turbine casting hub 1. When the wind turbine casting hub 1 needs to be limited, the first rotating shaft 44 can be driven to rotate under the drive of the first driving mechanism 6. At this time, the first rotating shaft 44 can drive the support arm 42 to rotate synchronously inside the accommodating groove 43 until the support arm 42 drives the arc-shaped support plate 41 to rotate in the direction close to the wind turbine casting hub 1, until the arc-shaped support plate 41 contacts the surface of the wind turbine casting hub 1.

[0051] Specifically, the first driving mechanism 6 includes a hydraulic cylinder 61, a slide groove 62, a driving seat 63, a first gear 64 and a gear tooth 65. The slide groove 62 is arranged on the surface of the base 2, and the driving seat 63 is slidably arranged inside the slide groove 62. The upper end of the driving seat 63 is fixed to the surface of the movable plate 51. The hydraulic cylinder 61 is installed on the inner wall of the base 2, and the output end of the hydraulic cylinder 61 is connected to the surface of the driving seat 63. The gear tooth 65 is arranged at the lower end of the driving seat 63, and the first gear 64 is fixed to the surface of the first rotating shaft 44.

[0052] See also Fig. 9 and Fig.10 The hydraulic cylinder 61 can drive the driving seat 63 to move laterally inside the slide groove 62. At this time, the driving seat 63 can drive the movable plate 51 to gradually approach the wind turbine casting hub 1, and the driving seat 63 can also drive the gear 65 to approach the first gear 64. As the driving seat 63 continues to move, the gear 65 can drive the first gear 64 to rotate, and then the first gear 64 drives the first rotating shaft 44 to rotate, so as to realize the rotation of the arc support plate 41. When the movable plate 51 is in contact with the surface of the wind turbine casting hub 1, the arc support plate 41 also happens to be in contact with the surface of the wind turbine casting hub 1. At this time, the wind turbine casting hub 1 can be laterally limited from two opposite directions by the arc support plate 41 and the movable plate 51.

[0053] Specifically, the second driving mechanism 8 includes a rack 81, a second gear 82, a reversing gear 83 and a second rotating shaft 84. The second rotating shaft 84 is rotatably arranged on the inner wall of the base 2. The rack 81 is fixed to the bottom of the arc-shaped support seat 71. The rack 81 passes through the surface of the base 2 and extends to the bottom of the base 2. The second gear 82 is fixed to the surface of the second rotating shaft 84. The reversing gear 83 is fixed to the surface of the first rotating shaft 44. The reversing gear 83 and the second gear 82 are meshed with each other, and the second gear 82 and the rack 81 are meshed with each other.

[0054] See also Fig. 9 and Fig.10 When the first rotating shaft 44 rotates, it can drive the reversing gear 83 to rotate synchronously. At this time, the reversing gear 83 can drive the second gear 82 to rotate. The rotation direction of the second gear 82 is opposite to that of the reversing gear 83. Therefore, the second gear 82 can push the rack 81 to move upward at this time. When the rack 81 moves upward, it can drive the arc support seat 71 to move upward synchronously until the arc support seat 71 contacts the bottom of the wind turbine casting hub 1. In the above process, when the movable plate 51 and the arc support plate 41 happen to contact the surface of the wind turbine casting hub 1, the arc support seat 71 also happens to contact the bottom of the wind turbine casting hub 1.

[0055] It should be noted that from Figure 2 and Figure 3 It can be seen that the arc support seat 71 limits the wind turbine casting hub 1 from the bottom thereof, but in the present embodiment, the straight line where the arc support seat 71 is located has been limited by the movable plate 51 and the arc support plate 41. Therefore, in the present embodiment, the arc support seat 71 can be rotated 90° and symmetrically processed so that the line connecting the two arc support seats 71 is exactly perpendicular to the line connecting the movable plate 51 and the arc support plate 41, so as to improve the stability of the wind turbine casting hub 1 during transportation.

[0056] Since there is no connection between the movable plate 51 and the wind turbine casting hub 1, the wind turbine casting hub 1 and the movable plate 51 are limited only by the pressure of the hydraulic cylinder 61 during transportation. There is a gap between the contact surface of the movable plate 51 and the wind turbine casting hub 1, and the wind turbine casting hub 1 may shake during transportation. Therefore, in this embodiment, a blocking mechanism 9 is provided on the movable plate 51, and the blocking mechanism 9 includes a base 91, a first movable rod 92, a second movable rod 93 and a limiting seat 94. The base 91 is fixed to the surface of the movable plate 51, the first movable rod 92 is hinged to the side of the base 91, the second movable rod 93 is elastically movably arranged at one end of the first movable rod 92, the limiting seat 94 is hinged to one end of the second movable rod 93, and the limiting seat 94 is slidably arranged on the surface of the movable plate 51, and a T-shaped slider 95 is fixedly arranged on the surface of the limiting seat 94, and a T-shaped track 96 is arranged on the surface of the movable plate 51, and the T-shaped slider 95 is slidably arranged inside the T-shaped track 96.

[0057] See also Figure 4 and Figure 5 When the movable plate 51 is close to the wind turbine casting hub 1, one end of the base 91 will gradually enter the inside of the wind turbine casting hub 1. At this time, the second movable rod 93 will gradually be squeezed by the edge of the wind turbine casting hub 1. When the second movable rod 93 is squeezed, one end of the second movable rod 93 will drive the limiting seat 94 to move in the direction close to the base 91 inside the T-shaped track 96 through the T-shaped slider 95, and the other end of the second movable rod 93 will elastically move toward the inside of the first movable rod 92, and the first movable rod 92 and the base 91 will also rotate. When the movable plate 51 contacts the surface of the wind turbine casting hub 1, the second movable rod 93 will resist the edge of the wind turbine casting hub 1 under the action of elastic force. Through the cooperation of multiple second movable rods 93, the connection strength between the movable plate 51 and the wind turbine casting hub 1 can be increased, thereby preventing the wind turbine casting hub 1 from shaking during transportation.

[0058] The present invention also provides a method for using a wind power casting transport tool, comprising the following steps:

[0059] S1, hoisting the wind turbine casting hub 1 by hoisting equipment and placing it on the base 2, so that the vertical limiting mechanism 3 pipe passes through the wind turbine casting hub 1, and the wind turbine casting hub 1 is vertically limited by the vertical limiting mechanism 3;

[0060] S2, the movable plate 51 moves towards the direction close to the wind turbine casting hub 1 under the driving of the first driving mechanism 6, and the first driving mechanism 6 drives the arc support plate 41 to rotate, and the wind turbine casting hub 1 is laterally limited from two different directions by the arc support plate 41 and the movable plate 51;

[0061] S3, the second driving mechanism 8 moves synchronously with the action of the first driving mechanism 6 to drive the arc-shaped support seat 71 to move upward, and the wind turbine casting hub 1 is supported and limited from the bottom through the arc-shaped support seat 71.

[0062] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
