Transformed grabbing bucket of slag dredging crane

Abstract

The invention discloses a transformed grabbing bucket of a slag dredging crane. The transformed grabbing bucket is specifically characterized in that a 6019 concentric ball bearing in a pulley block of the grabbing bucket of the crane is replaced by a sliding bearing processed by high-molecular nylon rods. By implementation of the transformed grabbing bucket, a wear-resistant and corrosion-resistant material is used for replacing the steel bearing without wear resistance and corrosion resistance, so that the wear and the corrosion of the bearing are reduced and the maintenance cost is reduced; simultaneously, the problem of frequent stop for repairing damage in the use process due to damage of the bearing is effectively relieved, the maintenance frequency of the bearing is obviously reduced, the production efficiency is improved, and simultaneously the production cost is also reduced, so that the purposes of saving cost and reducing maintenance are achieved.

Description

technical field [0001] The invention belongs to the modification of equipment in the field of sugar production, and in particular relates to a modified grab bucket of a slag removal crane. technical background [0002] The pulley block of the grab bucket of the slag crane that discharges the ash from the ash pool of the boiler usually uses radial ball bearings, but in order to scoop up the ash that sinks at the bottom of the pool, when the grab grabs the slag, the entire grab is submerged underwater . In sugar factories, a large amount of sugary waste water is continuously discharged into the ash settling tank, so the water quality of the whole ash settling tank is very bad. It not only contains a large amount of sediment, but also has an acidic pH value. When the crane grab sinks into the water, the bearings of the pulley block in the crane grab are often corroded by acidic water and worn by sediment that penetrates into the bearing gap, and are often corroded and worn.

Problems solved by technology

Therefore, the bearing will be damaged after a period of operation, and the higher the usage rate, the more serious the damage of the bearing will cause

As a result, the bearings of the grab pulley block need to be repaired or replaced frequently. When using radial ball bearings, it is only half a year at most, or even shorter; generally, one grab bearing is replaced each time, a total of 16 sets of 6019 radial ball bearings. For: 54 yuan / set, the total cost of replacing the whole grab bearing is about 864 yuan

In addition, due to the maintenance of the crane, the ash cannot be caught in time, so that the ash sinking tank is full of water, overflowing outside the tank and causing environmental protection accidents.

Therefore, the bearing maintenance or replacement of the grab pulley block is not only time-consuming and labor-intensive, but also the cost of maintenance and replacement parts is high.
