Description

Technical Field

[0001] This utility model belongs to the technical field of bearing hoisting equipment, and mainly relates to a wind turbine roller bearing hoisting device. Background Technology

[0002] Wind turbine roller bearings are key components in wind turbine generator sets, primarily used to withstand combined radial and axial loads. They also possess a certain degree of self-aligning capability to compensate for misalignment caused by installation errors or shaft deformation, ensuring stable operation of the wind turbine under complex conditions. Wind turbine roller bearings have a wide range of applications and come in various sizes. For storage and safety reasons, bearings are often placed horizontally. However, for larger bearings that need to be installed at higher locations, lifting shackles are used for hoisting. The lower end of the shackle secures the bearing, while the upper end connects to the hoisting ropes, allowing a crane to lift the bearing. However, existing shackles, once secured, are difficult to disassemble. When the bearing is hoisted to a high position, disassembling the shackles requires considerable time and effort, and does not provide adequate security for horizontally placed bearings, thus posing certain safety hazards during hoisting. Utility Model Content

[0003] The purpose of this utility model is to provide a wind turbine roller bearing hoisting device to solve the problems existing in the background art.

[0004] To achieve the purpose of this utility model, the technical solution adopted is as follows: A wind turbine roller bearing hoisting device includes a first fixed seat and a second fixed seat arranged vertically and vertically. Both the first fixed seat and the second fixed seat are provided with a central through hole structure, through which a vertically arranged tie rod is passed. The end of the first fixed seat is provided with a three-claw type hanger that extends downward evenly and a limiting rod. The end of the second fixed seat is provided with a support rod that extends horizontally evenly and a limiting block. The end of the hanger is also provided with a clamping part for clamping the bearing.

[0005] The clamping part is an L-shaped clamping seat, which is connected to the end of the hanger by screws.

[0006] The clamping part includes a clamping seat; the clamping seat is an L-shaped seat body, and a vertically arranged sliding groove is provided at the center of its inner surface; a lead screw is rotatably arranged in the sliding groove; a lead screw nut with threaded connection is provided on the lead screw; a clamping plate is provided on one side of the lead screw nut; a mounting hole is provided on the back of the clamping seat, and it is connected to the end of the hanger by screws.

[0007] The upper surface of the lower end of the clamping seat and the lower surface of the clamping plate are both provided with anti-slip layers.

[0008] The top of the pull rod is equipped with a lifting ring, and the lower part of the pull rod is equipped with a positioning nut at the junction with the second fixed seat.

[0009] The junctions between the hanger and the limiting rod and the first fixed seat are all hinged.

[0010] Both ends of the support rod are hinged to the second fixed seat and the joint of the support rod.

[0011] The end of the limiting rod is also provided with a limiting nut.

[0012] The first and second fixing seats are vertically aligned and are both Y-shaped fixing seats.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This device has a simple structure and is easy to operate. The three-jaw hanger and clamping part work together to increase the stability of the device and can be used to lift wind turbine roller bearings of various sizes.

[0020] The present invention will be described in conjunction with the accompanying drawings.

[0021] like Figures 1-3The wind turbine roller bearing hoisting device shown includes a first fixed seat 1 and a second fixed seat 2 arranged vertically and correspondingly. The first fixed seat 1 and the second fixed seat 2 are vertically aligned and both are Y-shaped. Both the first fixed seat 1 and the second fixed seat 2 have a central through-hole structure, through which a vertically arranged tie rod 3 passes. The end of the first fixed seat 1 is provided with a three-claw type hanger 4 extending downwards evenly and a limiting rod 5. The hanger 4 is designed as a three-claw structure to increase the stability of the device and can be adapted to various applications. The device employs hoisting of wind turbine roller bearings of various sizes. The end of the limiting rod 5 is also equipped with a limiting nut 12. The end of the second fixed seat 2 is equipped with evenly distributed horizontally extending support rods 6 and limiting blocks 7. Here, when the pull rod 3 is in the relaxed state, the limiting rod 5 moves downwards and can be locked between the limiting blocks 7. When the pull rod 3 is lifted, the limiting rod 5 moves upwards, and the limiting nut 12 on it can be locked with the limiting block 7 to ensure the stability of the device. The end of the hanger 4 is also equipped with a clamping part for holding the bearing.

[0022] The clamping part is an L-shaped clamping seat 8, which is connected to the end of the hanger 4 by screws 9. The clamping seat 8 is designed with an L-shaped structure, which can handle the lifting and transportation of small bearings with short lifting distances. The L-shaped seat can be directly clamped on the lower part of the bearing for lifting, thus improving the lifting efficiency.

[0023] The top of the pull rod 3 is provided with a lifting ring 10, and the lower part of the pull rod 3 is provided with a positioning nut 11 at the junction with the second fixed seat 2; the junctions of the hanger 4 and the limiting rod 5 with the first fixed seat 1 are all hinged; the two ends of the support rod 6 are also hinged at the junctions with the second fixed seat 2 and the support rod 6; the function of the positioning nut 11 here is to fix the pull rod 3 on the second fixed seat 2, and to make it linked with the support rod 6 and the hanger 4 when it is pulled up by the lifting ring 10, so that the hanger retracts; when the lifting ring 10 is relaxed downward, the support rod 6 and the hanger 4 retract, so that the hanger relaxes and expands.

[0024] Another embodiment of this utility model, such as Figures 4-5As shown, when hoisting large bearings over long distances, to strengthen the bearing's fixation and prevent it from loosening and falling during hoisting, the clamping part includes a clamping seat 8. The clamping seat 8 is an L-shaped seat with a vertically arranged sliding groove 81 at the center of its inner surface. A lead screw 82 is rotatably mounted within the sliding groove 81. A threaded lead screw nut 83 is mounted on the lead screw 82. A clamping plate 84 is provided on one side of the lead screw nut 83, allowing the bearing to be placed on the clamping seat 8. Rotating the lead screw 82 causes the lead screw nut 83 to move downwards along with the clamping plate 84 and fit against the upper end of the bearing. The bearing is fixed on one side by the clamping seat 8 and the clamping plate 84, which improves the stability of the bearing during hoisting. Furthermore, the device can select the appropriate clamping part for different working conditions, achieving the purpose of multiple uses. The back of the clamping seat 8 is provided with a mounting hole 85, and it is connected to the end of the hanger 4 by screws 9. The upper surface of the lower end of the clamping seat 8 and the lower surface of the clamping plate 84 are both provided with anti-slip layers.

[0025] In use, the crane is connected to the lifting ring 10. A suitable clamping part is selected for the corresponding wind turbine roller bearing model. Then, the pull rod 3 is lowered to allow the hanger 4 to unfold at a certain angle. The clamping part is then clamped and fixed to the bearing end face. Then, the pull rod 3 is lifted to allow the hanger 4 to retract and tighten. The limit nut 12 on the limit rod 5 is locked to the limit block 7 to ensure the stability of the device. The bearing can then be hoisted.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
