Description

Technical Field

[0001] This utility model relates to the field of fixing devices, specifically a device for fixing flanges. Background Technology

[0002] Wind turbine flanges are important intermediate components connecting wind turbine blades to the main shaft and wind turbine tower. They are crucial components in the wind power generation field, transmitting the rotation of the blades to the main shaft and supporting the weight of the entire wind turbine on the wind turbine tower. Wind turbine flanges generally consist of two parts: a flange plate and flange gaskets. The flange plate connects the blades to the main shaft or wind turbine tower and has high strength and stability. The flange gaskets are placed on both sides of the flange plate and serve to buffer, seal, and prevent loosening.

[0003] When producing wind turbine flanges, it is necessary to open holes and slots on the surface of the wind turbine flanges. In order to ensure the stability of the wind turbine flanges during drilling, corresponding fixing devices are required. Existing fixing devices can only clamp the wind turbine flanges, which has a relatively simple function. When drilling holes in different positions of the wind turbine flanges, the flanges cannot be rotated, which makes the drilling operation more troublesome and affects the drilling efficiency of the wind turbine flanges. Utility Model Content

[0004] The purpose of this utility model is to provide a device for fixing flanges to solve the problems mentioned in the background art, which has the advantage of fixing flanges while rotating and drilling.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for fixing a flange, comprising a fixing frame, a rotating component disposed on the fixing frame, a rotating disk rotatably connected above the rotating component, a fixing shaft integrally connected to the center of the rotating disk, and a fixing component for fixing the flange disposed above the fixing frame.

[0006] By adopting the above technical solution, the external flange can be placed on the rotating plate. When drilling is required, the flange is fixed by the fastener. It is worth noting that the fastener fixes the edge of the flange. When drilling is required in other positions of the flange, the rotating part is used to drive the flange to rotate, and then the fastener is used again to fix the flange, and the other position of the flange is drilled.

[0007] As a further embodiment of this utility model: the fixing member includes a top frame, on which a transverse cylinder is provided, the transverse cylinder is connected to a transverse moving block, the transverse moving block is connected to a longitudinal frame, the longitudinal frame is connected to a longitudinal cylinder, the longitudinal cylinder is connected to a longitudinal moving block, the longitudinal moving block is connected to a pressing cylinder, and the pressing cylinder is connected to a fixing plate.

[0008] By adopting the above technical solution, different flanges have different diameters. For flanges of different diameters, the horizontal cylinder is activated to drive the horizontal moving block to move, which in turn drives the longitudinal frame to move. After the longitudinal frame moves to the required position, the longitudinal cylinder is activated to drive the longitudinal block to move, which in turn drives the pressing cylinder to move. After the pressing cylinder moves, it drives the fixing plate to move away from or towards the flange. When one end of the fixing plate presses the edge of the flange, it can cooperate with the rotating disk and the fixing shaft to fix the flange.

[0009] As a further improvement of this utility model, a horizontal plate is integrally connected to one end of the fixing plate.

[0010] By adopting the above technical solution, the horizontal plate increases the contact area with one side of the flange.

[0011] As a further embodiment of this utility model: the top frame is fixedly connected to a limiting rail at one end of the longitudinal frame, a limiting block is slidably connected on the limiting rail, and the limiting block is fixedly connected to the longitudinal frame.

[0012] By adopting the above technical solution, the longitudinal frame moves, which drives the limiting block to move. The limiting block is restricted by the limiting track and can only move along the length direction of the limiting track. The setting of the limiting block increases the stability of the longitudinal frame during movement.

[0013] As a further embodiment of this utility model: the rotating component includes a rotating motor, the rotating motor is connected to a worm gear, the worm gear meshes with a worm wheel, and the worm wheel is fixedly connected to the rotating disk.

[0014] By adopting the above technical solution, the rotating motor drives the worm to rotate, which in turn drives the worm wheel to rotate, and the rotation of the worm wheel drives the rotating disk to rotate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The external flange can be placed on the rotating plate. When drilling is required, the flange is fixed with fasteners. It is worth noting that the fasteners fix the edge of the flange. When drilling is required in other positions of the flange, the flange is rotated by the rotating component, and then the flange is fixed with the fasteners again to drill in another position of the flange.
