Technical Field

The invention relates to a loading and unloading mechanical part which can be widely used in the production fields of construction, mining, transportation, environmental protection, agriculture, steel casting and the like, in particular to a split type pulley block grab bucket.

Background

In the field of steel casting, the grab bucket of the blast furnace water slag flushing treatment system frequently has the phenomena of steel rope falling and blocking of a pulley and a bearing when grabbing water slag, so that the operation is influenced due to frequent maintenance. The reason is deeply researched, firstly, the external working environment of the grab bucket is considered, the water temperature is higher than 70 ℃ due to the fact that the blast furnace water slag flushing treatment system adopts water circulation slag flushing, the specific concentration of slag in a slag pool is high, water mist is easily formed in an operation area if weather is bad, and the maintenance environment of the grab bucket operation is dangerous to a certain extent; secondly, the operation of the grab bucket is continuous in actual production, the grab bucket needs to operate at high temperature and high load for a long time, and the grab bucket is easy to collide with objects with unknown overlarge gradient to tip over when being grabbed underwater, so that the grab bucket is inevitably worn; in addition, the pulley block of the traditional grab bucket is designed in a built-in mode and is not suitable for underwater grabbing operation.

Therefore, lubricating grease of a pulley block bearing of the grab bucket is easy to dilute at high temperature and enter grain slag particles, the blocking phenomenon of the pulley and the bearing occurs, meanwhile, the abrasion of each part of the grab bucket is aggravated by high-temperature and high-load continuous operation, an overlarge fit clearance is formed, when a certain abrasion value is reached, when the sight is not good, the steel rope is easy to fall off the track and block accidents are easy to occur due to an overlarge underwater gradient. The pulley blocks of the traditional grab bucket are all designed in a built-in mode, are not suitable for grabbing operation in water, and are easy to block

For the maintenance of the accidents, the operation of the grab bucket is stopped firstly, and then the fault parts are manually dismounted one by one on the grab bucket body and then reloaded one by one, which is labor-consuming and time-consuming; if the problem occurs to the upper pulley group, the time is longer. When the steel rope falls off the way, the steel rope must be removed again and then rewound in the pulley groove to recover the steel rope. The two common faults have the defects of long time consumption for maintenance and extremely unfavorable safety for maintenance due to high-altitude operation.
