Abstract
The utility model discloses a safety protection device preventing a plate mill guide and guard device from falling. The safety protection device comprises an upper supporting roller main balance beam and the mill guide and guard device. A balance beam pull rod support is installed on the upper supporting roller main balance beam of a mill. A protection pull rod is hinged to the mill guide and guard device in the vertical direction. The upper portion of the protection pull rod is installed on the pull rod support, wherein a buffering disc spring is installed on the protection pull rod in a sleeved mode. The safety protection pull rod is used for connecting the mill guide and guard device and the main balance beam of the mill into one, and therefore the safety protection device can effectively prevent the mill guide and guard device from falling and improves the work stability of the mill.
Description
Technical field
The utility model relates to a kind of plate mill guide and guard anti-falling safe protection device.
Background technology
Cut deal 3500x4 finishing mill roller guide and guard unit is connected as a single entity rolling mill guiding and mill balancing beam by lifting hydraulic cylinder, makes rolling mill guiding follow top working roll and moves up and down together.Due to hydraulic system, there is the factor impacts such as pressure oscillation and pipeline leakage, easily cause rolling mill guiding to fall down in running, cause rolled piece to rush the serious equipment breakdown of rolling mill guiding.
Summary of the invention
The purpose of this utility model is to provide a kind of plate mill guide and guard anti-falling safe protection device, can effectively prevent that rolling mill guiding from falling, and improves milling train job stability.
The purpose of this utility model is to realize like this; a kind of plate mill guide and guard anti-falling safe protection device; comprise the main equalizer bar of upper backup roll and roller guide and guard unit; on the main equalizer bar of milling train upper backup roll, equalizer bar drag link bearing is installed; a vertical articulated protection pull bar on roller guide and guard unit; be set with its top of protection pull bar of cushioning dish spring and be arranged on described drag link bearing, by safe protective pull rod, roller guide and guard unit and rolling mill main equalizer bar are being connected as a single entity.
Roller guide and guard unit is connected as a single entity roller guide and guard unit and the main equalizer bar of milling train upper backup roll by guide and guard lift cylinder, roller guide and guard unit is under the effect of guide and guard lift cylinder overbalance power, roller guide and guard unit hook is leaned against on top working roll backplate, and servo-actuated together with top working roll.On the main equalizer bar of milling train upper backup roll, equalizer bar drag link bearing is installed, guide and guard drag link bearing is installed on roller guide and guard unit, by safe protective pull rod, roller guide and guard unit and rolling mill main equalizer bar are connected as a single entity.The in the situation that of hydraulic system fails, can there is not the guide and guard accident that falls down yet.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of plate mill guide and guard anti-falling safe protection device; as shown in Figure 1; comprise and be arranged on the milling train main equalizer bar of 1 upper backup roll and roller guide and guard unit 5; on the main equalizer bar of milling train upper backup roll, equalizer bar drag link bearing 2 is installed; a vertical articulated protection pull bar 4 on roller guide and guard unit; be set with protection pull bar 4 its tops of cushioning dish spring 3 and be arranged on described drag link bearing 2, by safe protective pull rod 4, roller guide and guard unit 5 and rolling mill main equalizer bar are being connected as a single entity.
