Description

Technical Field

[0001] The utility model relates to the technical field of aviation engine assembly, and more specifically to a hoisting device for aviation engine components. Background Art

[0002] In the field of aircraft engines, the lifting operation of aircraft engine components is extremely critical for maintenance and assembly work. Usually, the existing lifting device mainly clamps and hooks the outer edge of the top of the engine through components such as outer hooks to achieve lifting. However, this method is prone to many problems when lowering and installing engine components. Due to the relatively simple clamping method and the lack of comprehensive and stable support, the engine components are very easy to tilt and shake during the descent process. The aircraft engine components are large in size, and it is not easy to rotate the aircraft engine components to adjust the posture of the aircraft engine components during the lifting process. When shaking occurs, the installation position is prone to misalignment, which will not only prolong the installation time and reduce work efficiency, but may also cause the components to collide with surrounding structures, causing damage to the surface of the components, affecting their performance and service life. Utility Model Content

[0003] The utility model aims to provide a hoisting device for aircraft engine components, which limits the position of the engine components to prevent the engine components from shaking during the hoisting and transfer process, resulting in misalignment during hoisting, thereby affecting the installation efficiency.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A lifting device for aircraft engine parts includes a base, a sleeve fixedly connected at the center of the upper surface of the base, a hanging column slidably connected in the sleeve, a plurality of sliding grooves surrounding the sleeve on the base, a connecting arm slidably connected in the sliding groove, a connecting rod is provided between the connecting arm and the hanging column, two ends of the connecting rod are respectively hinged to the connecting arm and the hanging column, one end of the connecting arm extends to the outside of the base and is fixedly connected to an L-shaped hook, and a positioning column is provided at the bottom of the base.

[0006] Furthermore, a through hole is provided on the base, a screw is threadedly connected to the through hole, a limiting plate is fixedly connected to the top of the screw, the limiting plate is located above the base, the bottom of the screw extends to the bottom of the base, a through groove is provided in the positioning column, an internal thread is provided in the through groove, and the positioning column is threadedly connected to the screw.

[0007] Furthermore, a plurality of through holes are provided.

[0008] Furthermore, the L-shaped hook includes a horizontal portion and a vertical portion, and an end of the horizontal portion away from the vertical portion is provided with a chamfer.

[0009] Furthermore, a hanging ring is provided on the hanging column.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The base is moved to above the engine component, the positioning column is inserted into the corresponding groove of the engine component, the crane pulls the hanging column to rise, and the hanging column drives the connecting arm to move along the slide groove through the connecting rod, so that the L-shaped hook is close to the engine component and hooks the top edge of the engine component, and the engine component is lifted as the base rises; the utility model realizes the limitation of the engine component by inserting the positioning column with the engine component, so as to avoid the shaking of the engine component during the lifting and transfer process, resulting in misalignment during lifting, thereby affecting the installation efficiency.
