Abstract
The utility model provides an auxiliary lifting device of a rolling mill, which is characterized in that: a lifting hydraulic cylinder is arranged at an operation side of a vertical rolling mill and a piston rod of the lifting hydraulic cylinder downwards stretches out to form a support with a lifting mechanism at two ends of the vertical rolling mill. According to the utility model, the support is formed at the two ends of the vertical rolling mill by the lifting mechanism and the auxiliary lifting device so as to synchronize the lifting and the falling of the auxiliary lifting device, so that not only can a tipping problem in a lifting process of a main body of the vertical rolling mill be solved, but also a lifting force is provided in an auxiliary mode; the vertical rolling mill is guaranteed to be stably lifted; meanwhile, the stability of the rolling mill is improved in a rolling process; a load of the lifting mechanism is reduced and the error rate of equipment is reduced; and the structure is simple and compact.
Description
Technical field
The utility model relates to a kind of milling train lifting device, relates in particular to a kind of vertical mill service hoisting device.
Background technology
Tradition milling train specification is little, equipment is light, has been difficult to satisfy rolling specifications section and has constantly added
Big big bar demand.After the milling train specification strengthened, weight of equipment increased a lot, thereby had brought the lifting problem of big specification vertical mill.Hydraulic cylinder or spiral lift are generally adopted in the lifting of traditional vertical milling train, and its elevating mechanism is arranged on transmission side, are difficult to overcome the tilting moment that milling train body gravity is caused, and can't effectively accomplish the lifting of milling train.
The utility model content
The purpose of the utility model is to provide a kind of milling train service hoisting device that can prevent effectively that milling train from tumbling.
The purpose of the utility model is achieved in that a kind of milling train service hoisting device, and it is characterized in that: the vertical mill fore side is provided with the lifting hydraulic cylinder, and its piston rod stretches out downwards with hoisting mechanism and forms support at the two ends of vertical mill.
Above-mentioned piston-rod lower end is supported on the pre-embedded steel slab.
Above-mentioned piston-rod lower end is fixed with pressing plate and links to each other with breading cap, and the surface of said pressing plate is sphere and cooperates and form spherical pair with sphere on the said breading cap that adjustment adapts to the offset of vertical mill voluntarily.
Above-mentioned hoisting mechanism is hydraulic cylinder or spiral lift.
Above-mentioned hoisting mechanism is arranged on transmission side.
Piston rod elongation gradually downwards when promoting vertical mill, auxiliary lifting mechanism promotes vertical mill synchronously; After lifting put in place, during vertical mill work, piston rod was all withdrawn; During the vertical mill landing, withdrawal gradually after piston rod stretches out fast, auxiliary lifting mechanism falls vertical mill synchronously.
The utlity model has following beneficial effect, the utility model and hoisting mechanism form at the vertical mill two ends and support, synchronously the lifting and the landing of auxiliary lifting mechanism; Solve the problem of tumbling in the vertical mill body lifting process, and auxiliary lifting force is provided, guaranteed the steady lifting of vertical mill; Improve the stability of milling train when rolling, not only alleviated hoisting mechanism load, reduced equipment failure rate; And improved production efficiency, simple in structure, compact.
Description of drawings
Fig. 1 is the initial position to be hoisted of a utility model embodiment vertical mill sketch map;
Fig. 2 is rolling position sketch map for the utility model embodiment vertical mill rises to.
The specific embodiment
Embodiment, a kind of milling train service hoisting device referring to Fig. 1, comprises promoting hydraulic cylinder 1, pressing plate 2, breading cap 3, pre-embedded steel slab 4, vertical mill 5 and hoisting mechanism 6.Hoisting mechanism 6 is spiral lift and the transmission side that is arranged on vertical mill 5, promotes hydraulic cylinder 1, pressing plate 2, breading cap 3 and pre-embedded steel slab 4 and is the linear fore side that vertically is arranged in vertical mill 5.Lifting hydraulic cylinder 1 cylinder body is connected and is installed in vertical mill 5 tops; And its piston rod stretches out downwards; The piston rod end is fixed with pressing plate 2, and the surface of pressing plate 2 is sphere and cooperates the spherical pair that constitutes with sphere on the breading cap 3, can adjust the offset that adapts to vertical mill 5 voluntarily.
The hoisting mechanism 6 that above-mentioned service hoisting device is used for the accessory drives side is the lifting and the landing of spiral lift, forms two end supports vertical mill 5 with spiral lift.The not only auxiliary lifting force that provides, main solution the vertical mill 5 bodies problems of in lifting process, tumbling.Improved the stability of vertical mill 5 when rolling simultaneously.
Referring to Fig. 2, promote hydraulic cylinder 1 piston rod during lifting and stretch out gradually downwards, auxiliary lifting mechanism 6 spiral lifts promote vertical mill 5 synchronously; During vertical mill 5 landing, piston rod is withdrawn gradually, and auxiliary synchronously spiral lift 6 falls vertical mill.
