Description

Technical Field

[0001] The utility model relates to the technical field of rotary mechanisms, in particular to an anti-impact protective device for rotary mechanisms. Background Art

[0002] The slewing mechanism is a mechanism installed on certain transfer equipment to rotate around the center line of rotation in the horizontal plane. The function of the slewing mechanism is to realize the horizontal movement of goods. Through the coordinated action of the three mechanisms of lifting, luffing and slewing, the goods can be transported to any position within the working range of the equipment.

[0003] However, when the console of the slewing mechanism is hit by external force, it is easy to cause the driving components (especially the transmission gears) of the slewing mechanism console to be slightly damaged, or even positional displacement, resulting in the slewing mechanism being unable to operate normally and affecting the normal operation of the equipment. Secondly, the existing slewing mechanism only controls the operation of the console through a single supporting device, resulting in poor stability of the console during operation. In response to the above problems, the inventor proposes a slewing mechanism anti-impact protection device to solve the above problems. Utility Model Content
