Abstract

The invention discloses a hoisting tool for a paddle blade and belongs to the field of mechanical assembly. The hoisting tool comprises a mounting component, a hoisting component and a connecting arm.The mounting component comprises a first pin shaft, a lining and a fixing component. One end of the first pin shaft is mounted at one end of the connecting arm. The other end of the first pin shaft is used for penetrating a hoisting hole in the paddle blade. A limiting protrusion is arranged in the middle of the first pin shaft. The limiting protrusion abuts against one side of the paddle blade.The other end of the first pin shaft is sleeved with one end of the lining and the end of the lining abuts against the other side of the paddle blade. The lining is arranged on the first pin shaft through the fixing component. The hoisting component comprises a second pin shaft and a hoisting ring. One end of the second pin shaft is mounted at the other end of the connecting arm. A limiting plateis arranged at the other end of the second pin shaft. The outer rim of the limiting plate protrudes out of the outer peripheral wall of the second pin shaft. The hoisting ring is slidably arranged atthe other end of the second pin shaft. The hosting ring is located between the connecting arm and the limiting plate. By the adoption of the hoisting tool, steady and smooth hoisting of the paddle blade is achieved.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, in particular to a hoisting tool for blades. Background technique [0002] The blade is one of the important components of the controllable pitch propeller. [0003] When processing and assembling the blades, the blades are usually bound by slings to realize the hoisting of the blades. However, due to the special-shaped structure of the blade, it is not easy to achieve a stable binding of the blade through the sling. If the operation is improper, it will cause the blade to tilt, unable to achieve balanced hoisting, and even cause the blade to fall, resulting in safety accidents and economic losses. . Contents of the invention [0004] In order to solve the problem that the blade is difficult to hoist, an embodiment of the present invention provides a hoisting tool for the blade. Described technical scheme is as follows: [0005] An embodiment of the present invention provides a hoisting t...
