Description

Technical Field

[0001] This utility model belongs to the field of high-voltage motor installation technology, specifically relating to high-voltage motor brackets, and more particularly to brackets for high-voltage motor structures. Background Technology

[0002] In production line or temporary equipment environments, motors require higher mounting positions and drive unit replacements, but there is a mismatch between the height of the motor and the transmission unit. Traditional motor mounting brackets use a single-layer fixed structure, which cannot adapt to the differences in shaft height between different motor models (usually with an installation tolerance of ±50mm), making it difficult to align with the transmission unit. In order to adapt to different assembly environments, related technologies use multi-layer assembled brackets.

[0003] In addition, multi-layer self-assembly brackets require on-site cutting, welding, or bolt connection and locking, which increases the installation time by an average of 2-3 hours per unit. They are also prone to damaging the equipment foundation, resulting in low overall installation efficiency. In situations where the equipment layout needs to be changed frequently, such as production line renovation (e.g., 3-5 production line reorganizations per year), the cut or welded brackets cannot be put back into use. Furthermore, repeated disassembly and reassembly of the locking structure (bolts) can easily lead to wear between adjacent brackets and cause loosening.

[0004] Therefore, how to solve the low reuse rate of multi-layer brackets is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0034] Research has revealed the following drawbacks of existing technologies: In production lines or temporary equipment environments, motors require higher mounting positions and drive unit replacements, but there is a mismatch between the height of the motor and the transmission unit; traditional motor mounting brackets use a single-layer fixed structure, which cannot accommodate the differences in shaft height between different motor models (usually with an installation tolerance of ±50mm), making it difficult to connect with the transmission unit. In order to adapt to different assembly environments, related technologies use multi-layer assembled brackets.

[0035] In addition, multi-layer self-assembly brackets require on-site cutting, welding, or bolt connection and locking, which increases the installation time by an average of 2-3 hours per unit. They are also prone to damaging the equipment foundation, resulting in low overall installation efficiency. In situations where the equipment layout needs to be changed frequently, such as production line renovation (e.g., 3-5 production line reorganizations per year), the cut or welded brackets cannot be put back into use. Furthermore, repeated disassembly and reassembly of the locking structure (bolts) can easily lead to wear between adjacent brackets and cause loosening.

[0036] Therefore, how to solve the low reuse rate of multi-layer brackets is a technical problem that urgently needs to be solved in this field.
