Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, and particularly relates to a telescopic and adjustable yaw bearing horizontal hoisting device. Background Art

[0002] The yaw system, also known as the wind alignment device, is a part of the nacelle of a wind turbine. Its function is to quickly and smoothly align with the wind direction when the direction of the wind speed vector changes, so that the wind turbine can obtain the maximum wind energy.

[0003] During the assembly and hoisting of wind turbine units in the workshop, the hoisting distances corresponding to the hoisting of yaw bearings and brake discs in yaw systems with different power ratings are different, and different horizontal hoisting devices are required. Therefore, there are problems of operation safety for the staff adjusting the platform device in a low space and low assembly efficiency of the yaw system. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a telescopic and adjustable yaw bearing horizontal hoisting device. The two support bases on both sides of the horizontal hoisting device adopt a quick telescopic adjustment structure. By quickly adjusting the distance between the support bases, it can adapt to the hoisting of yaw bearings with different power ratings, improving the versatility of the horizontal hoisting device in the assembly workshop of wind turbine units.

[0005] The utility model provides a telescopic and adjustable yaw bearing horizontal hoisting device, and the specific technical solution is as follows:

[0006] The device includes support bases, a lifting beam body, guide rails and limit columns; the guide rails are fixedly connected to the lifting beam body. There are two guide rails, which are respectively arranged at both ends of the same-side end face of the lifting beam body. There are two support bases, which are respectively arranged at both ends of the lifting beam body. The two guide rails are respectively placed in the sliding grooves of the corresponding two support bases. The support bases can slide along the axis of the lifting beam body through the guide rails; limit holes are provided on the support bases, and the limit columns are inserted into the limit holes.

[0007] Through the sliding connection between the guide rails and the sliding grooves of the support bases, the two support bases can slide along the rails. By adjusting the distance between the support bases, the distance dimension of the horizontal hoisting device can be adjusted to adapt to the unit components with different power ratings. After the distance adjustment is adapted, the unit components can be stabilized on the horizontal hoisting device through the limit columns to complete the hoisting. After that, the horizontal hoisting device is removed, and the distance between the support bases is adjusted again to adapt to other unit components, and the hoisting adaptation of different unit components can be quickly completed.

[0008] Further, the device further includes a spacing adjustment screw. The rod body of the spacing adjustment screw axially penetrates through the support base along the hanging beam body and extends into the threaded hole of the hanging beam body. An adjustment thread adapted to the threaded hole is provided on the rod body. By rotating the spacing adjustment screw, the spacing between the two support bases can be adjusted.

[0009] By providing the spacing adjustment screw, the screw can be rotated by a power tool, facilitating the rapid adjustment of the spacing.

[0010] Further, one end of the spacing adjustment screw outside the support base is provided with a head, and the size of the head is larger than the aperture of the through hole through which the spacing adjustment screw penetrates the support base.

[0011] Through the setting of the head structure, the existing power tools can be adapted to dock with the head to rotate the spacing adjustment screw. At the same time, by directly pushing the support base with the head, the precise adjustment of the spacing between the support bases can be realized.

[0012] Further, a limit nut and a locking nut are also provided on the rod body of the spacing adjustment screw. The limit nut and the locking nut are arranged between the inner side of the support base and the hanging beam body. The sizes of the limit nut and the locking nut are larger than the aperture of the through hole through which the spacing adjustment screw penetrates the support base.

[0013] Through the limit nut and the locking nut, the rotation of the spacing adjustment screw can be locked, and at the same time, the telescopic progress of the spacing adjustment screw can be limited.

[0014] Further, a fixing plate is also provided in the hanging beam body, and the fixing plate is arranged at the opening of the threaded hole.

[0015] By providing the fixing plate to surround the rod body, the stability of the rod body during rotation adjustment can be ensured.

[0016] Further, the guide rail includes a slide rail and a guide plate. The guide plate is fixedly connected to the end face of the slide rail, and a lifting hole is provided on the guide plate.

[0017] Based on this guide plate structure, the symmetry of the lifting points is realized, making the lifting force stable, ensuring the stability of the lifting process, and at the same time, based on the guide plate, ensuring the stability of the horizontal lifting device during spacing adjustment.

[0018] Further, the support base is integrally of a T-shaped structure, including a sliding part connected to the slide rail and a support part vertically and integrally connected to the sliding part. A guide groove communicating with the chute is provided on the sliding part, and the guide plate is placed in the guide groove.

[0019] The support base is arranged according to the T-shaped structure of the sliding part and the supporting part, so that the sliding part can slide smoothly along the slide rail, and at the same time ensure that the horizontal lifting device can stably support the unit components.

[0020] Furthermore, a limiting block is arranged at the tail end of the sliding part.

[0021] The setting of the limiting block prevents the support base from detaching from the slide rail during the process of spacing adjustment.

[0022] Furthermore, an end face structure perpendicular to the guide groove is arranged at the bottom of the guide plate on the side of the limiting block and the supporting part of the support base where it is located.

[0023] Based on this end face structure at the bottom of the guide plate, it is ensured that the support base can be stably restricted when quickly expanding the adjustment spacing.

[0024] Furthermore, two symmetrical limiting holes are arranged on the supporting part, and two limiting posts are correspondingly arranged.

[0025] The limiting posts are symmetrically inserted on the supporting part, ensuring the stability of the unit components on the horizontal lifting device.

[0026] The beneficial effects of the present utility model are as follows:

[0027] For the horizontal lifting device provided by the present utility model, the support bases on both sides realize sliding along the lifting beam body through the chute and the slide rail. At the same time, a rapid telescopic adjustment structure between the support base and the lifting beam body is constituted by the spacing adjustment screw rod, so that the spacing of the supporting part of the horizontal lifting device can be adjusted quickly and flexibly, adapting to the yaw bearings and brake discs in yaw systems with different power ratings, improving the versatility of lifting use, ensuring the safety and speed of lifting adjustment operations, greatly reducing the labor intensity of operators in low spaces, and improving the assembly efficiency of the yaw system.
