Description

Reinforcing device for lower pulley shaft of granulated slag grab bucket

Technical Field

The utility model belongs to the technical field of wheel axle reinforcing equipment, and particularly relates to a lower wheel axle reinforcing device of a granulated slag grab bucket.

Background

The water slag grab bucket is used for grabbing water quenching slag discharged by a copper smelting and depositing electric furnace, after the smelting of copper concentrate in a top-blown pizza furnace is finished, the copper concentrate is separated by electric furnace deposition, slag is discharged from the electric furnace, the slag flows to a water quenching port through a chute, is rapidly cooled by water to form water quenching slag, is flushed into a water slag pool, and then the water slag in the water slag pool is fished up and stored and loaded by a gantry grab bucket crane for transportation. In the prior art, the granulating slag travelling crane is provided with two groups of motor drums, each group of drums leads out two steel wire ropes, two of the two groups of steel wire ropes respectively take roots at two ends of a grab bucket balancing stand for supporting, the other group of steel wire ropes passes through a pulley of an upper cross beam and a pulley of a lower cross beam to form a pulley block to play a role in opening and closing a bucket part, a lower pulley block of the grab bucket consists of 4 pulleys and a main shaft, in the whole grabbing process, the lower pulley block of the grab bucket continuously receives an upward lifting acting force, the lower pulley block of the grab bucket is in high-temperature and highly corrosive water for a long time, and the main shaft of the lower pulley often deforms and bends to cause the grab bucket to be incapable of being used.

Therefore, it is necessary to provide a lower pulley shaft reinforcing device for a granulated slag grab bucket, so that the long-term effective work of the grab bucket is ensured, the service life of the granulated slag grab bucket is prolonged, the production order is ensured, and the labor intensity of workers is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a reinforcing device for a lower pulley shaft of a granulating slag grab, which aims to solve the problems that the lower pulley block of the grab is continuously subjected to the upward lifting acting force, the lower pulley block of the grab is in high-temperature and highly corrosive water for a long time, and a main shaft of the lower pulley is often deformed and bent, so that the grab cannot be used.

In order to realize the purpose, the utility model is realized by the following technical scheme:

the utility model provides a reinforcing device for a lower pulley shaft of a granulated slag grab bucket, which comprises a reinforcing plate 1, a shaft sleeve 2 and two locking devices 3; the middle of the reinforcing plate 1 is provided with a through hole, the shaft sleeve 2 is embedded into the through hole and is fixedly welded with the reinforcing plate 1, the two locking devices 3 are fixedly connected to two sides of the lower pulley big frame 4, and the left end and the right end of the reinforcing plate 1 are detachably connected with the two locking devices 3 respectively.

Preferably, the top parts of the left end and the right end of the reinforcing plate 1 are provided with hanging lugs, fixing holes are reserved on the hanging lugs, the two locking devices 3 are provided with threaded holes matched with the fixing holes, and the reinforcing plate 1 is connected with the locking devices 3 through fastening bolts 5.

The utility model has the beneficial effects that:

the reinforcing plate is adopted to fix the middle part of the main shaft of the lower pulley shaft of the granulating hopper, so that the bending and deformation of the lower pulley shaft of the granulating hopper are reduced, the reinforcing device can effectively bear corresponding acting force, the load of the lower pulley shaft is reduced, the service life of the granulating hopper is prolonged, the normal operation of equipment is ensured, and the equipment is simple in structure, simple to operate and convenient to disassemble and maintain.
