On-line steel scrap dumper

Abstract

The invention relates to a dumper, particularly to an on-line steel scrap dumper, which includes a dumper base, pulling fingers and pulling finger brackets, wherein each pulling finger is fixedly connected with one end of each pulling finger bracket through a rotating shaft, the other end of each pulling finger bracket is fixed on the dumper base through the rotating shaft; and wear-resistant blocks are arranged on the inner surfaces of the pulling fingers. According to the on-line steel scrap dumper, the wear condition of the pulling fingers can be well improved, the service cycle of the pulling fingers can be greatly prolonged, friction between the pulling finger brackets and a billet is greatly reduced, failure rate of equipment is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a dumper, in particular to an online dumper for scrap steel. Background technique [0002] According to the applicant's understanding, the material of the claws of the steel turning machine is 16Mn. The dumpers currently on the market mainly have the following problems: 1. The middle part of the claws will rub against the steel billet if the steel billet is turned up by the bucket machine. This is the main reason for the easy wear and tear of the claws; 2. Because the claw bracket design of the original dumper did not take into account the friction between the bracket and the steel billet during the return process of the claws, so that the steel billets will be pulled by the claws during the return process. Bring back a certain distance, this phenomenon will make the operation of the equipment not stable enough, also affect the surface quality of the billet, and indirectly affect the wear of the bearing bush and the service lif...
