[0002] When assembling the planetary carrier in the speed reducer, due to its large weight and lack of gripping position, it is difficult to properly install the planetary carrier into the housing. Therefore, this utility model utilizes the planetary carrier retaining spring groove to design a tooling that can quickly grip, lock, and automatically open. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 and Figure 2 As shown, a planetary carrier three-head rapid lifting device includes: a lifting base plate 1, which includes three outwardly extending supports 2, and a through hole is provided in the center.
[0021] A hoisting limiting plate 3 is fixedly connected to the bottom surface of the end of the support 2. A through groove is opened along the center line of the top of the hoisting limiting plate 3, and the groove and the bottom surface of the support 2 form a sliding channel. A hoisting claw 4 is slidably arranged in the sliding channel. The first end of the hoisting claw 4 is adapted to the planetary carrier spring groove, and the bottom of the second end is provided with a rotating connecting seat 5. A connecting rod 6 is hinged to the rotating connecting seat 5; the rotating connecting seat 5 can also limit the range of backward movement of the hoisting claw 4.
[0022] like Figure 2 and Figure 3 As shown, a shaft 7 is slidably disposed within the through hole. The bottom end of the shaft 7 is located below the lifting base plate 1, and a connecting rod fixing frame 8 is fixedly sleeved on its bottom end. The connecting rod fixing frame 8 is hinged to the other end of the connecting rod 6, so that the shaft 7 can drive the lifting claw 4 to move. The top end of the shaft 7 is located above the lifting base plate 1, and a handle 9 is connected to its top end. The handle 9 has a cylindrical structure, is coaxially disposed with the shaft 7, and its diameter is larger than the diameter of the through hole, so it cannot extend into the through hole, thus limiting the range of movement of the shaft 7 within the through hole, and consequently limiting the range of forward movement of the lifting claw 4.
[0023] The top surface of the mounting base plate 1 is provided with a reinforcing rib 10. The center of the reinforcing rib 10 is provided with an opening corresponding to the through hole, and the end extends to the end of the support 2. The height of the reinforcing rib 10 gradually decreases from its center to its end.
[0024] Preferably, the first end of the lifting claw 4 is configured as a stepped structure. The upper half of the stepped structure can extend into the circlip groove of the planetary carrier, and the lower half can abut against the top of the planetary carrier. This serves to limit the depth of the lifting claw 4 end inserted into the circlip groove, prevent the lifting claw 4 end from colliding violently with the bottom of the circlip groove, and protect the lifting device and the planetary carrier.
[0025] The end of the lifting limiting plate 3 is designed with an arc-shaped contour groove structure that adapts to the planetary carrier, facilitating the positioning of the lifting device with the planetary carrier. Simultaneously, the bottom surface of the support 2 has an arc-shaped slot that adapts to the arc-shaped contour groove structure, with the depth of the arc-shaped slot being less than or equal to half the depth of the lifting base plate 1. The arc-shaped structures at the ends of the support 2 and the lifting limiting plate 3 facilitate the engagement of the lifting device with the top of the planetary carrier.
[0026] Work process: such as Figure 4 As shown, with the lifting claw 4 retracted, the lifting device is placed on top of the planetary carrier. Then, the shaft 7 is pulled upward by the handle 9. The shaft 7, through the connecting rod 6, drives the lifting claw 4 to move forward in the sliding channel, so that its end engages with the planetary carrier's retaining spring groove, thus achieving a fixed connection between the lifting device and the planetary carrier. Then, the planetary carrier can be lifted by the lifting device. After the planetary carrier is installed, the shaft 7 is pushed downward, causing the lifting claw 4 to retract and disconnecting the lifting device from the planetary carrier.
[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
