[0013] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0014] like Figure 1-3 The auxiliary lifting device for assembling a reducer shown in the figure includes a mounting plate 1 and grabbing assemblies mounted on both sides of the mounting plate 1. Both sets of grabbing assemblies include a moving rod 9, two support rods 6, and a movable block 8. The moving rod 9 is movably mounted on the end of the mounting plate 1. The two support rods 6 are fixedly mounted on the ends of the moving rod 9. The bottom end of the support rod 6 is fixedly mounted with a slide plate 7. The outer wall of the slide plate 7 is provided with a slide groove. A rotating rod 13 is installed inside one end of the movable block 8. The end of the rotating rod 13 is movably mounted inside the slide groove of the slide plate 7. The movable block 8 is in the shape of a triangular prism. A plurality of fixing frames 2 are fixedly mounted on the upper outer wall of the mounting plate 1. A lifting rod 3 is fixedly mounted on the top of the fixing frame 2. The bottom outer walls of both ends of the lifting rod 3 are provided with grooves.

[0015] Two groups of cylinders 1 4 are symmetrically mounted on both sides of the upper portion of the mounting plate 1. Cylinder 2 5 is mounted between the two groups of cylinders 1 4. The output end of cylinder 1 4 is fixedly connected to the moving rod 9. The output end of cylinder 2 5 passes through the moving rod 9 and is fixedly connected to a connecting rod 10 through the output end of the moving rod 9. A notch is provided on one side of the movable block 8. The connecting rod 10 is a U-shaped rod. One end of the connecting rod 10 is fixedly connected to the outer wall of the rotating rod 13 through the notch of the movable block 8. Two notches 11 and one notch 2 12 are symmetrically provided on the outer walls of both sides of the mounting plate 1. The support rod 6 is embedded in notch 11. The opening position of notch 2 12 corresponds to the installation position of the connecting rod 10. Notch 1 11 and notch 2 12 are arranged in parallel.

[0016] Example: The lifting rope of the crane is tied to both ends of the lifting rod 3, and then the auxiliary lifting device is driven to the position of the reducer housing, and the auxiliary lifting device is lowered. In the initial state, the movable blocks 8 on both sides of the mounting plate 1 do not contact the ends of the reducer housing. The beveled edge of the movable block 8 is aligned with the end of the reducer housing. Cylinder 1 4 recovers the output end, and one end of the beveled surface of the movable block 8 is moved toward the end of the housing. The end edge of the movable block 8 enters the bottom gap of the end of the housing, and the end of the housing is lifted. After the movable block 8 passes, the end of the housing falls on the slide plate 7, and the support rod 6 is in contact with the outer wall of the housing. When cylinder 1 4 recovers the output end, cylinder 2 5 operates synchronously, the moving rod 9 operates on the mounting plate 1, the support rod 6 slides in slot 1 11, and the connecting rod 10 slides in slot 2 12. Slots 11 and 2 12 control the running direction of the support rod 6 and the connecting rod 10. The connecting rod 10 drives the rotating rod 13 and the movable block 8 to operate together.

[0017] After the end of the housing falls above the chute plate 7, cylinder 2 5 extends its output end again, and the connecting rod 10 drives the rotating rod 13, which in turn drives the movable block 8 toward the inner wall of the housing. The end of the rotating rod 13 slides within the chute of the chute plate 7 until the outer wall of the movable block 8 is in contact with the inner wall of the housing. The movable block 8 and the support rod 6 clamp the end of the housing inside and outside. The operator then starts the crane, which drives the lifting rope. The lifting rope connects the entire auxiliary lifting device to the fixed housing through the lifting rod 3 and lifts it to the installation station. The auxiliary lifting device automatically clamps the end of the housing, eliminating manual handling and improving production efficiency.

[0018] It should be noted that the parts not covered in the present invention are the same as the existing technology or can be implemented by using the existing technology; the various drives in the present invention can be implemented by using corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structure in the drawings.

[0019] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
