Abstract
The invention discloses a hydraulic roll changing device for a rolling mill work roller. The hydraulic roll changing device for the rolling mill work roller comprises a fixing shelf arranged at the front end of the rolling mill work roller, the outer side wall of the fixing shelf is jointed with a hydraulic support rod, which is arranged obliquely and upwards, the end of the hydraulic support rod is connected with a hydraulic oil cylinder flatly arranged, the hydraulic oil cylinder is connected with the a pull rod provided with a drag hook and hanged to the rolling mill work roller corresponding to the end of the rolling mill work roller; the hydraulic oil cylinder is horizontally located above the fixing shelf and the lower part of the middle thereof is jointed to the end of the hydraulic support rod through a connection end; the hydraulic roll changing device for the rolling mill work roller is simple in structure, convenient and reliable in use, can raise the roll changing efficiency and reduce the use cost.
Description
Technical field
What the present invention relates to is a kind of hydraulic pressure changing rig for operation roll of mill, belongs to the supporting roll change mechanism technical field of operation roll of mill roller system.
Background technology
In prior art, making with steel is mainly by mill milling, the supporting working roll roller system had for rolled band steel of described milling train, due to working roll roller, system often needs roll change, just require easily working roll roller system to be pulled out from milling train or to send to once needs roll change, realize roll change; Being undertaken by fork truck of current this roll change; Because the volume of fork truck own is comparatively large, turnover inconvenience in milling train, efficiency is low, is therefore badly in need of a kind of changing rig that conveniently can pass in and out milling train.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, roll change efficiency can be improved, reduce the hydraulic pressure changing rig for operation roll of mill of use cost.
The object of the invention is to have come by following technical solution, a kind of hydraulic pressure changing rig for operation roll of mill, it comprises the fixed mount that can be placed in operation roll of mill roller system front end, one lateral wall of described fixed mount is hinged with a hydraulic supporting strut arranged obliquely, be connected to a horizontally disposed hydraulic jack in the end of this hydraulic supporting strut, the end of this hydraulic jack relative operation roll of mill roller system is connected with one can be mounted on operation roll of mill, band drag hook pull bar.
Described hydraulic jack level is unlikely to the top of fixed mount, and the below in the middle part of it is articulated with the end of described hydraulic supporting strut by connecting end portion.
The present invention mainly uses hydraulic cylinder to solve the problem of operation roll of mill roller system turnover difficulty, and alternative fork truck realizes roll change work easily; It is simple that it has structure, easy to use and reliable, can improve roll change efficiency, reduces the features such as use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of hydraulic pressure changing rig for operation roll of mill of the present invention, it comprises the fixed mount 1 that can be placed in operation roll of mill roller system front end, one lateral wall 2 of described fixed mount 1 is hinged with a hydraulic supporting strut 3 arranged obliquely, be connected to a horizontally disposed hydraulic jack 4 in the end of this hydraulic supporting strut 3, the end of the relative operation roll of mill roller system of this hydraulic jack 4 is connected with one can be mounted on operation roll of mill, the pull bar 6 of band drag hook 5.Shown in figure, described hydraulic jack 4 is horizontally disposed in the top of fixed mount 1, and the below in the middle part of it is articulated with the end of described hydraulic supporting strut 3 by connecting end portion 7.
