Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, specifically to a special lifting tool for heat treatment of high-temperature alloy ball forgings. Background Technology
[0002] When gripping spherical forgings, traditional gripping methods often use spherical cage-shaped grippers. These grippers use multiple arc-shaped claws to wrap around the outer surface of the sphere and radially converge to generate frictional force for clamping. The positioning requirements for gripping are very strict. The spherical cage must completely cover the sphere to apply force evenly. If there is a deviation in the initial positioning, it will lead to uneven distribution of clamping force, causing the sphere to shift or rotate. An additional visual correction system is required, which is costly. Therefore, we propose a special lifting tool for heat treatment of high-temperature alloy spherical forgings.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other methods that a person skilled in the art can obtain without creative effort are within the scope of protection of this utility model.
[0027] See attached document Figure 1-5 A special lifting tool for heat treatment of high temperature alloy ball forgings, the alloy ball includes a ball body and a through groove provided thereon, the through groove extends along the diameter direction of the ball body, its central axis passes through the center of the ball body, and the openings at both ends of the through groove are located at the antipodal points on the surface of the ball body respectively.
[0028] The lifting device also includes a base 11 with a cavity and a guide post 1 coaxially connected to the base 11. The output shaft of the motor 12 extends through the through hole of the guide post 1 to the cavity of the base 11. The drive gear 13 is fixed to the end of the output shaft. The motor 12 is fixedly connected to one end of the guide post 1. The motor 12 is located at the end of the guide post 1 away from the base 11. The output end of the motor 12 extends along the through hole of the guide post 1 to the cavity of the base 11. The drive gear 13 is connected to the output end of the motor 12.
[0029] At least two racks 23 are reciprocatingly slidably arranged in the cavity of the base 11. The protruding ends of the racks 23 are provided with anti-slip textures. The racks 23 mesh with the drive gear 13. When the motor 12 drives, the slide rail 2 is arranged radially along the cavity of the base 11. The slider 21 drives the racks 23 to move linearly along the slide rail 2. The drive gear 13 can simultaneously drive multiple racks 23 evenly distributed in the circumference to extend and retract synchronously. The racks 23 slide out from the groove opened in the circumference of the base 11 to the outside of the base 11. Specifically, when hoisting is required, the crane is fixedly connected to the fixed lug on the side of the guide column 1 of this equipment, and drives the guide column 1 downward from one end of the through groove of the ball to the other end. The motor 12 drives the racks 23 to slide out to the outside of the base 11. The crane lifts, and the racks 23 abut against the ball to complete the hoisting.
[0030] At least two slide rails 2 are provided on the bottom wall of the base 11 chamber. The slide rails 2 are arranged around the drive gear 13. A connecting block 22 is fixedly connected to the slider 21 that slides on the slide rail 2. The rack 23 is fixedly connected to the connecting block 22 and meshes with the drive gear 13. The rack 23 is fixed by rigid connection to maintain a stable meshing relationship with the drive gear 13 and prevent the rack from deviating or dislodging.
