Problems solved by technology

[0004] In the use of the above two kinds of hangers, large deformation will occur at the place with the greatest stress. If it is light, the bent shaft needs to be thermally straightened, and if it is serious, it will cause plastic deformation and cause the bent shaft to be scrapped.
[0005] Therefore, it is necessary to develop a new type of hanger to prevent the occurrence of the above phenomenon, avoid unnecessary thermal straightening and scrapping of the bent shaft

Embodiment

[0015] Example: such as figure 1 As shown, a kind of leverage ratio adjustable hanger includes a hanger 1, a hook 2, a tray frame 5, a tray 6 and two adjustable rods 7, and the tray frame 5 is composed of two vertical bars parallel to each other, each The lower ends of the vertical rods are respectively fixedly connected to the tray 6, and the upper ends are respectively connected to the ends of an adjustable rod 7. The two adjustable rods 7 are provided with a number of suspension holes 3 and the other ends are symmetrically connected to each other. On the hook 2, the lower part of the hanger 1 is two hanging rods 11, and the lower end of each hanging rod 11 is connected to one of the hanging holes 3 on an adjustable rod 7 through a pin rotation.

[0016] The top of the hanger 1 is provided with a hanging hole.

[0017] When the bent shaft 4 is hung on the present invention, since the lever structure where the hanging hole 3 is located distributes the gravity in proportion, ...

Abstract

The invention discloses a hanger with an adjustable lever ratio. The hanger comprises a hanging rack, a hook, a tray support, a tray and two adjustable rods, wherein the tray support is composed of two parallel vertical rods, lower ends of both vertical rods are fixedly connected with the tray respectively, upper ends of both vertical rods are rotatably connected with one ends of adjustable rods respectively, a plurality of hanging holes are arranged on the two adjustable rods, the other ends of adjustable rods are symmetrically rotatably connected with the hook in an opposite mode, the lower portion of the hanging rack comprises two hanging rods, and the lower end of each of the two hanging rods is rotatably connected with one of the hanging holes on one adjustable rod through a pin respectively. The hanger has the advantages that the gravity of a bending shaft is distributed at two points again, so that the stress value produced by the gravity can be greatly reduced; hanging holes can be selected according to deformation conditions of the bending shaft, so that the deformation amount of the bending shaft can be minimized; and adjustable rods can be rotated, so that the additional stress produced by different shaft body linear expansion coefficients between the bending shaft and the two vertical rods which form the tray support can be prevented.

Description

technical field [0001] The invention relates to a hanger, in particular to a hanger with adjustable leverage ratio. Background technique [0002] In the field of machinery manufacturing, irregularly shaped slender shafts (hereinafter referred to as bent shafts) are loaded with different racks during storage or heat treatment, and the magnitude, direction and position of the gravity they bear are different, resulting in deformation Not the same. [0003] If a suspension hanger is used, the upper end of the bent shaft bears all its own weight, and the tensile stress borne by the rest gradually decreases from top to bottom, and the bottom end is zero; if a pallet-type hanger is used, the bottom end of the bent shaft bears all its own weight, The compressive stress borne by the remaining parts gradually increases from top to bottom, and the top end is zero. [0004] In the use of the above two kinds of hangers, large deformation will occur at the place with the greatest stress...
