Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to speed reducer installation device. Background Technology

[0002] As a widely used transmission device in industrial equipment, the installation sequence of a speed reducer typically varies depending on the size and type of the equipment. For large equipment, the main equipment is usually assembled first, followed by the speed reducer; while for smaller equipment, the speed reducer can be installed first, followed by equipment assembly. However, regardless of the installation sequence, the speed reducer needs to be raised to a certain height for proper docking with the equipment.

[0003] In traditional gear reducer installation, even small gear reducers are too heavy for an average person to lift alone, usually requiring multiple people or auxiliary equipment such as cranes. This method is not only complex to operate, but also difficult to meet installation needs in some situations due to space limitations or insufficient equipment. Especially in confined spaces or densely packed equipment, the use of large equipment such as cranes may be restricted, leading to low installation efficiency or even failure to complete the installation task.

[0004] Furthermore, the collaborative installation of speed reducers by multiple people not only increases labor costs but also poses certain safety risks. Due to the significant weight of the speed reducer, improper operation during installation may lead to equipment damage or personal injury. Therefore, simplifying the installation process, reducing installation difficulty, and improving installation efficiency have become urgent problems to be solved. Utility Model Content
