Description
Technical Field
The utility model relates to a landing gear, especially a synchronous landing gear of hydraulic generator guide bearing oil pan belongs to mechanical design and makes technical field.
Background
The guide bearing oil bottom basin of the large-scale hydroelectric generating set is mostly fixed on the lower part of the frame in a bolt connection mode, and the oil bottom basin needs to fall down when the unit is overhauled and leakage defects are treated. However, the oil bottom basin of the guide bearing of the large-scale unit has larger ground distance, the operation space is complicated, and the total weight of the bearing cooler and the oil bottom basin is more than 5 tons. In the past, when an oil pan is disassembled and assembled, rack jacks are required to be used for supporting in four directions, four-position operators operate the jacks to slowly rise and fall under the oil pan, and other operators assist in measurement and carrying. Because the oil pan rises and falls by about 1.5 meters, and the travel of the rack jack is limited, the number of battens needs to be increased or reduced for many times below the oil pan, so that the supporting point of the jack is unreliable, and the safety risk of toppling the oil pan exists. In addition, the rising and falling heights of the oil pan are measured from four directions by using a steel plate ruler in the working process, so that the phenomenon that the guide rod is broken due to overlarge deviation of the oil pan in the rising and falling process is avoided. A great deal of adverse factors cause great potential safety hazards in the oil pan dismounting process, and the time and the labor are wasted. There is therefore a need for improvements in the prior art.
Disclosure of Invention
