Anti-impact damping device for bucket door of excavator bucket
The invention discloses an anti-impact damping device for a bucket door of an excavator bucket. The anti-impact damping device comprises a bucket door pin, a bucket body pin, a base and a damping assembly, wherein the base is installed on a bucket body on one side of a pin shaft; the damping assembly comprises a shaft sleeve, a first partition plate, a second partition plate, a friction plate, a thick bolt shaft, a spring and a spacer sleeve; one end of the shaft sleeve is installed in an installation hole of the base; the first partition plate, the second partition plate and the friction plate are installed on the shaft sleeve in a sleeving mode; the friction plate is arranged between the first partition plate and the second partition plate; the end, away from the shaft sleeve, of the first partition plate and the end, away from the shaft sleeve, of the second partition plate are fixedly connected with the bucket door pin and the bucket body pin correspondingly; one end of the thick bolt shaft stretches into the shaft sleeve, and a gap is formed between the thick bolt shaft and the base; the thick bolt shaft is sleeved with the spring which is in a compressed state; the first partition plate, the second partition plate and the friction plate are pressed between the base and the spacer sleeve; the spacer sleeve is locked through a nut. According to the anti-impact damping device, the impact force of the bucket door to the bucket body is relieved; the anti-impact damping device is small in size and not prone to damage; and when the friction plate is abraded, the gap of the friction plate can be eliminated through the spring, and normal pressure is kept between the friction plate and the partition plates.
本发明公开了一种挖掘机铲斗斗门的防冲击阻尼装置，包括斗门销、斗体销、底座和阻尼组件，底座安装在销轴一侧的斗体上；阻尼组件包括轴套、第一和第二隔板、摩擦片、粗螺栓轴、弹簧和挡套，轴套一端安装在底座的安装孔；第一、二隔板和摩擦片套装在轴套上，摩擦片设置在第一隔板和第二隔板之间；第一、第二隔板远离轴套一端分别与斗门销和斗体销固连；粗螺栓轴一端伸入轴套内与底座之间形成间隙；粗螺栓轴上套有弹簧，弹簧呈压缩状态；第一、二隔板、摩擦片被压紧在底座和挡套之间，挡套由螺母锁紧。该装置减缓了斗门对斗体的冲击力；其体积小、不易损坏；摩擦片被磨损时，弹簧能消除其间隙，使摩擦片和隔板保持正常压力。
