Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a device for grinding steel bars in construction. Background technique [0002] In the field of construction, it is often necessary to grind the steel bars, such as grinding off the ribs or rust on the head, so as to add strain gauges or facilitate knotting of steel bars. [0003] During the operation process of such steel bar grinding, flying chips generated due to the fast running of the grinding wheel are likely to cause danger to the operator. However, some current security shielding measures are often run manually. This method is likely to cause potential safety hazards when the operator forgets to operate the safety shield to drop, and setting a special power drive mechanism to detect and execute the fall of the safety shield will cause an increase in cost and inconvenience in maintenance. [0004] Therefore, it is necessary to provide a new technical solut...
