Description

Technical Field

[0001] The utility model relates to the technical field of fan maintenance, and more specifically, to a fan main engine cabin overturning hanger. Background Art

[0002] The wind turbine nacelle is an important part of the wind turbine, located at the top of the wind turbine tower. It is the outer shell of the wind turbine and contains the main components of the wind turbine, such as the generator, gearbox and control system. The design and construction of the nacelle should be able to protect the equipment inside from severe weather conditions, while providing the necessary ventilation and cooling systems to ensure the normal operation of the wind turbine. The equipment in the nacelle may require maintenance and repair, such as replacement of parts or inspection and cleaning. The flip hoist can flip the nacelle to a vertical position, making it easier for maintenance personnel to work.

[0003] Among them, after searching, it was found that the patent application number CN201621233730.7 discloses a maintenance crane and a wind turbine nacelle using the maintenance crane, which belongs to the field of lifting equipment. The maintenance crane includes a mounting support, a column, a cantilever frame, a hoist and a control mechanism. The cantilever frame includes a retractable fixed arm frame and a retractable arm frame;

[0004] When in use, this structure is fixed to the mounting support by a column and is used to support structures such as a cantilever frame. The cantilever frame is connected to the column and the cantilever frame rotates around the column. The control mechanism can control the movement of the hanger on the cantilever frame. By dividing the suspension arm into two retractable parts, the length of the suspension arm can be adjusted as needed. When the telescopic arm frame is retracted, the length of the suspension arm can be reduced, so that the maintenance crane can achieve 360° rotation in a smaller space. However, this structure cannot ensure the stability of the cabin when it is flipped when in use, causing it to shake easily during flipping and low stability after adjustment, resulting in inconvenience in cabin maintenance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a fan main engine cabin flip hanger, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The utility model is implemented in this way. The utility model provides the following technical solutions: a fan main engine cabin flip hanger comprises two supporting columns, the two columns are arranged opposite to each other, and a supporting assembly is arranged between the two columns;

[0007] The support assembly comprises a support frame arranged between two columns, the support frame is a rectangular frame structure, and a first clamping plate with adjustable position is arranged on one side of the inner wall of the support frame, and a second clamping plate for isolation is arranged on the other side of the inner wall of the support frame;

[0008] An extension plate for blocking the cabin is disposed on one side of the first clamping plate and the second clamping plate, a support rod for supporting is disposed at the bottom of the inner wall of the support frame and at the bottom of the first clamping plate and the second clamping plate, the support rod is slidably connected to two sliding sleeves for supporting, and an L-plate for supporting is disposed on the two sliding sleeves, and each L-plate extends to the bottom of the first clamping plate and the second clamping plate respectively and is detachably connected to the first clamping plate and the second clamping plate;

[0009] It can be seen that in the above technical solution, it is placed at the bottom of the inner cavity of the support frame, and is first lifted by the support drag rod. When the first clamping plate is displaced, the extension plate on the first clamping plate is driven to approach the extension plate on the second clamping plate, thereby realizing the function of clamping and limiting the cabin, and the extension plate extends the contact area between the first clamping plate, the second clamping plate and the workpiece;

[0010] Optionally, in a possible implementation, a screw rod is provided on the top of the support frame, a turntable located on the side of the support frame is provided at one end of the screw rod, guide rods installed on the support frame and used for guiding are provided on both sides of the screw rod, an inner thread sleeve installed on the first clamping plate is threadedly connected to the outer side of the screw rod, a guide sleeve installed on the first clamping plate is slidably connected to the guide rod, a driving motor for driving is provided on one side of the top of one of the two columns, rotating shafts rotatably connected to the columns are provided on both sides of the support frame, and an output end of the driving motor extends to one of the rotating shafts and is detachably connected to the rotating shaft;

[0011] It can be seen that in the above technical solution, when the screw rod rotates, it rubs against the inner thread sleeve, thereby causing the inner thread sleeve to drive the first clamping plate to move. Through the arrangement of the guide sleeve and the guide rod, it can play a guiding and limiting role when the first clamping plate is moved, thereby ensuring the stability of the workpiece when it is placed. At the same time, when the device is in use, the driving motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the support frame to rotate, thereby realizing the function of flipping the cabin in the support frame.

[0012] Technical effects and advantages of the utility model:

[0013] By setting the support assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, the cabin is placed at the bottom of the inner cavity of the support frame, and is first lifted by the support drag rod. When the first clamping plate is displaced, the extension plate on the first clamping plate is driven to move closer to the extension plate on the second clamping plate, thereby realizing the function of clamping and limiting the cabin, and the extension plate extends the contact area between the first clamping plate, the second clamping plate and the workpiece;

[0014] When the screw rod rotates, it rubs against the inner thread sleeve, which then drives the first clamping plate to move, making it easy for the device to clamp the workpiece and ensure the stability of the workpiece when it is placed. At the same time, when the device is in use, the driving motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the support frame to rotate, thereby realizing the function of flipping the cabin in the support frame, thereby improving the diversity of the device when in use.
