The invention relates to the technical field of cranes, and discloses a European style crane speed reducer with a protection device.The European style crane speed reducer comprises a fixing mechanism, the fixing mechanism further comprises an equipment bottom plate, and a sliding square plate is slidably connected to the outer wall of the top of the equipment bottom plate. When a power motor moves backwards, an outer column and a sliding rod are pulled to move in the same direction, a limiting plate is driven to be close to a gear through hole groove, and when the limiting plate and the gear through hole groove are not matched in position, the sliding square plate still moves backwards, and a telescopic spring accumulates mechanical power; and after the limiting plate is matched with the gear through hole groove in position, the limiting plate loses resistance and moves towards the interior of the gear through hole groove, so that the limiting plate is matched with the gear through hole groove, and the speed reduction procedure is started.
本发明涉及起重机技术领域,且公开了一种欧式起重机用带有防护装置的减速机,包括固定机构,所述固定机构还包括有设备底板,所述设备底板的顶部外壁处滑动连接有滑动方板,本发明在降低动力马达的转速时,接通电动伸缩杆的电源,使滑动方板向设备外壳的边缘靠近,此时动力马达向后移动时拉扯外柱与滑动杆向相同方向移动,带动限位板向齿轮通孔槽方向靠近,当限位板与齿轮通孔槽位置不匹配时,滑动方板依旧向后移动,并使伸缩弹簧积蓄机械动力,当限位板与齿轮通孔槽位置匹配后,限位板失去阻力,向齿轮通孔槽内部移动,使限位板与齿轮通孔槽契合,开始降速工序。
