At present, in the large-sized strip milling equipment, often adopt twin columns plug cylinder formula bascule.
Adopt double plunger formula cylinder bascule, as Fig. 1-shown in Figure 4, double plunger formula hydraulic cylinder 91 is arranged in milling train entablature 92 center line both sides, provoke balance link plate 95 by shoulder pole girder 93 by raising rod 94 and lifting beam 96, fuel feed hole 911 is arranged on the bottom of hydraulic cylinder 91, adopts flanged pipe 912 and threeway 913 to connect in-line.Existing guide and guard lift cylinder 97 is installed on the memorial archway 98 and since guide and guard 99 will with the working roll servo-actuated, therefore each milling train carries out opening degree when adjusting, the stroke of guide and guard lift cylinder is all wanted the respective change adjustment, action frequency is more frequent.
Summary of the invention
The objective of the invention is to, a kind of milling train top backing up roll bascule is provided, can reduce the adjustment frequency of guide and guard lift cylinder, prolong the service life of hydraulic cylinder.
Above-mentioned purpose of the present invention can adopt following technical scheme to realize, a kind of top backing up roll bascule of milling train, and this milling train includes entablature, and wherein this top backing up roll bascule comprises:
Shoulder pole girder is positioned at above the entablature of milling train;
The balance link plate is connected on the described shoulder pole girder;
The guide and guard lift cylinder, it is connected on the balance link plate.
In the present invention, described guide and guard lift cylinder is connected on the balance link plate by a guide and guard lift cylinder hitch.
In a concrete example, described balance link plate is provided with the connection seam, and an end of described guide and guard lift cylinder hitch is stuck in and connects in the seam, and is connected on the described balance link plate by fastening connection piece.
In another concrete example, described balance link plate is provided with recess or keyway, correspondence is provided with protuberance or key on described guide and guard lift cylinder hitch, described protuberance or key are stuck in described recess or the keyway, and this guide and guard lift cylinder hitch is connected on the described balance link plate by fastening connection piece.
In another optional example, described guide and guard lift cylinder hitch is welded on the described balance link plate.
In another optional example, described guide and guard lift cylinder hitch and balance link plate are provided with corresponding pin-and-hole, and a plurality of pins are located in the described pin-and-hole, and by a plurality of fastening connection pieces this guide and guard lift cylinder hitch are connected on the described balance link plate.
The top backing up roll bascule of milling train of the present invention goes for strip-mill strip, is particularly suitable for the needs of roller series balance on the large-sized strip milling train.
Guide and guard lift cylinder of the present invention is connected on the balance link plate, because the roller of top working roll and top backing up roll footpath is a determined value in a roll change cycle, so guide and guard lift cylinder stroke also is a determined value in a roll change cycle, reduce the adjustment frequency of guide and guard lift cylinder, prolonged the service life of hydraulic cylinder.And, for the milling train that roll shifting control is arranged, hang over the guide and guard lift cylinder on the balance link plate after, can guarantee that guide and guard are close to the working roll backplate, be convenient to again control suitable overbalance power, when roll shifting, obtain smaller frictional force, reduce the wearing and tearing of slide plate.
