Problems solved by technology

[0002] For some large workpieces, it is not easy to clamp around the shape, the workpiece entrance is small, and the overall height space is limited. The existing lifting tooling is difficult to use, and it will be tilted and unstable during hoisting, posing safety hazards;
[0003] Taking a circular workpiece with a convex cross-section as an example, since its outer circumference is smooth cylindrical and its height is close to the bottom, it is difficult to fix it from the outer circumference with general hoisting tools, and there is a great risk in hoisting; then It is necessary to consider hoisting from its inner hole. However, due to its convex cross-section, the apertures at both ends are larger, while the middle aperture is smaller. No matter which end the hoisting tool enters the inner hole, the ring-shaped boss in the middle will affect the hoisting. The entry of tooling, the existing lifting tooling is difficult to achieve

Embodiment Construction

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] like Figure 1-Figure 2 As shown, a hoisting tool includes a mounting frame and a gear set, the gear set is arranged on the mounting frame, and the gear set includes a sun gear 1 and three planetary gears 2 meshing with the sun gear 1 , and the three planetary gears 2 are evenly distributed along the outer circumference of the sun gear 1;

[0038] The sun gear 1 is mounted on the mounting frame through a first rotating shaft 9 , and the planetary gear 2 is mounted on the mounting frame through a second rotating shaft 10 .

[0039] The sun gear 1 is connected to the first rotating shaft 9 through a large spline, the first rotating shaft 9 is rotatably mounted on the mounting frame, and the planetary gear 2 is...

Abstract

The invention relates to a hoisting tool. The hoisting tool comprises a mounting frame and a gear set. The gear set is arranged on the mounting frame, and comprises a sun gear and at least two planetary gears engaged with the sun gear, and the planetary gears are evenly distributed along the outer periphery of the sun gear. Supporting jaws corresponding to the planetary gears one to one are further included, and the planetary gears can drive the supporting jaws to rotate. The hoisting tool can be suitable for hoisting large workpieces with large boundary dimensions, the outer peripheries not easily clamped, the small heights and small inlets. The invention further relates to an assembly method of the hoisting tool. The assembly method includes the step of mounting the sun gear on the mounting frame, the step of evenly distributing the supporting jaws along the sun gear and the step of mounting an angle scale, regardless of whether the number of outer teeth of the sun gear is an integermultiple of 3 or not, it can be guaranteed that the supporting jaws are evenly distributed at the angles of 120 degrees, and therefore the hoisting stability is guaranteed.
