Description

Gear box oil change equipment

Technical Field

The utility model relates to the technical field of nuclear power, in particular to gearbox oil changing equipment.

Background

The number of the crane devices in the nuclear power plant is large, the distribution is wide, and for example, a CPR1000 type nuclear power plant is taken as an example, and about 137 cranes and 24 nuclear fuel loading and unloading devices are arranged in 6 units. The crane and the nuclear fuel loading and unloading equipment are both composed of a translation mechanism and a lifting mechanism, and a gear box is one of the most main mechanical driving components of the translation mechanism and the lifting mechanism. Because the gear working process needs to use lubricating oil for lubrication, heat dissipation, rust prevention and the like, after the lubricating oil is used for a certain period of time, the viscosity, the purity and the like of the lubricating oil change, the performance of the lubricating oil is affected, and the service life of the gear is further affected, so that the lubricating oil in the gear box needs to be replaced periodically. Roughly, the amount of lubricating oil used once by a CPR1000 model nuclear power plant crane and a nuclear fuel handling equipment gearbox is about 12016 liters.

The crane and the nuclear fuel loading and unloading equipment translation mechanism and the lifting mechanism are generally located at high altitude, the traditional oil change adopts a manual carrying mode, new oil is carried to the crane and the nuclear fuel loading and unloading equipment, and the oil is slowly added into the gear box through the oilcan, so that the workload is large, the efficiency is low and the operation risk is high. Taking a main crane of an MX factory building of a nuclear power plant as an example, one main crane consists of a main lifting mechanism, an auxiliary lifting mechanism, a trolley mechanism and a trolley mechanism, wherein the capacity of a gear box of the main lifting mechanism is 320L, the capacity of a gear box of the auxiliary lifting mechanism is 90L, the capacities of gear boxes of motors of two trolley are 30L, and the capacities of gear boxes of motors of four trolley are 30L.

In the oil change process, maintenance personnel need to carry new oil to a main crane in a factory building, transfer the new oil component into a 5L oil pot and fill into a gear box. The calculation is carried out according to the sum of the gear box capacity of each mechanism of a main crane and 590L, an operator needs to carry a safety belt and other protection devices to carry the 16L oil drum up and down for 37 times in the oil change process, and then the oil can with the capacity of 5L is used for filling 118 times. In addition, the old oil is discharged and carried, and the workload is doubled. According to the operation experience, the oil change work of a main crane needs 5 people, takes 1 week, and has low efficiency.

Meanwhile, the device is influenced by factors such as high temperature of a factory building, high noise and the like, and the probability of error of staff is increased in the environment for a long time.

According to the 6 units of the nuclear power plant and the requirement of changing gear box oil in 5-6 years, a large number of cranes and nuclear fuel loading and unloading equipment need to alternately change gear oil every year, the defects of large workload, long construction period, high bearing risk and the like exist, and most of cranes and nuclear fuel loading and unloading equipment even do not need to get on a car or get off an inclined ladder, and the oil is required to be lifted to the equipment by adopting a manual pull rope, so that the risk is extremely high.
