Abstract
The utility model relates to the field of removal of a rolling mill pressurizing device, in particular to an ejector for removing the rolling mill pressurizing device. The ejector is characterized by comprising an upper platform, a lower platform, a double-end stud and an oil press, wherein the upper platform and the lower platform are connected in parallel through the double-end stud; the oil press is arranged between the upper platform and the lower platform; a hole of which the outer diameter is matched with that of a hydraulic cylinder of the rolling mill pressurizing device is formed in the upper platform; first reinforcing ribs are arranged on the upper plane of the upper platform; and second reinforcing ribs are arranged on the lower plane of the lower platform. Compared with the prior art, the ejector for removing the rolling mill pressurizing device has the advantages that 1) the ejector is simple in structure and convenient to construct, and can quickly remove the rolling mill pressurizing device during maintenance of the rolling mill pressurizing device, construction time is greatly shortened, and material cost and time cost, which are consumed for making large temporary measures, are saved; and 2) by repeated practical application, the maturity and reliability of the ejector can be fully embodied, ejection pressure in the removal process can be eliminated in the ejector, and damage to a rolling mill main frame is avoided.
Description
Technical field
The utility model relates to rolling mill pressing device and removes the field, relates in particular to a kind of top tool of removing rolling mill pressing device.
Background technology
At present, the method that domestic existing rolling mill pressing device is removed generally is to lay large-scale temporary steel structure platform below milling train, utilizes hydraulic press top rolling mill pressing device at platform, until pressuring upper device is pulled down, the problem of its existence is:
1) expend great deal of steel and make interim measure, length expends time in;
2) narrow field below the milling train, the construction operation difficulty;
3) place below the milling train, concrete year is loose for a long time, very easily causes immerge;
4) when the pressuring upper device hydraulic cylinder of top, simultaneously milling train integral body there is top power upwards, milling train there is damage.
Summary of the invention
The purpose of this utility model is to provide a kind of top tool of removing rolling mill pressing device, and simple in structure, easy construction can be removed rolling mill pressing device when the maintenance rolling mill pressing device rapidly, avoids milling train main body frame injury.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of top tool of removing rolling mill pressing device, comprise upper mounting plate, lower platform, studs and hydraulic press, upper mounting plate passes through the parallel connection of studs with lower platform, and hydraulic press places between upper mounting plate and the lower platform, and upper mounting plate is provided with the hole with rolling mill pressing device hydraulic cylinder external diameter coupling.
The upper plane of described upper mounting plate is provided with reinforcement one, and the lower plane of lower platform is provided with reinforcement two.
Compared with prior art, the beneficial effects of the utility model are: 1) simple in structure, easy construction, when the maintenance rolling mill pressing device, can rapidly rolling mill pressing device be removed, greatly shortened the construction period, material cost and the time cost of making large-scale interim measure have been saved, under the prerequisite that guarantees repair quality, created preferably economic benefit.2) through repeatedly practical application, fully shown its maturity and reliability, the pressure on top surface of top tool within digestion demolishing process has been avoided milling train main body frame injury.
