Abstract
The invention relates to a rolling mill safety protection device for a cold rolling mill, which comprises a transverse beam with a track, wherein a fixed push-pull door frame is arranged at the outer side of the transverse beam with the track, the upper end of the fixed push-pull door frame is fixed on the transverse beam with the track, and a push-pull door is configured in the fixed push-pull door frame; and a left movable door and a right movable door are connected in the track in the transverse beam with the track, the right movable door is driven by an air cylinder, a movable door locking pedal is installed on the fixed push-pull door frame, and one end of the movable door locking pedal is connected with the left movable door. When the rolling mill safety protection device for the cold rolling mill is used, the push-pull door is closed, the right movable door is driven to leftwards move by the air cylinder, the movable door locking pedal is stepped down, and the left movable door is manually pulled rightwards until the left movable door and the right movable door are gathered. At this moment, the movable door locking pedal is lifted up for locking the left movable door. If the conditions of loosening and throwing out parts or rupturing and throwing out band steel occur at the state of working of the rolling mill, dangerous goods can be obstructed by the device so as to ensure the personal safety of a worker. The rolling mill safety protection device for the cold rolling mill has the advantages of simple structure and reliable performance.
Description
Technical field
The invention belongs to the auxiliary equipment field of cold-rolling mill, be specifically related to a kind of milling train safety device for cold-rolling mill.
Background technology
Improving constantly of the automatization level of domestic cold rolling unit at present, unit maximum speed increases, rolling rate is greatly improved, once but occur as an accident such as broken belt loses, coiling machine roll coil of strip driving, bolt and pin fracture throw away, will serious threat arrive operator's personal safety.Domestic cold rolling unit is not equipped with relevant safeguard at present.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of milling train safety device for cold-rolling mill, there is simple in structure, dependable performance.
