Abstract

The invention discloses a method for straightening pendulous railhead on site. In the method, the rails are not dismantled, torque support M can be adjusted, and the methods of artificial force application on leverage and hydraulic transmission are used. The invention also discloses a hydraulic pressure railhead straightener, which mainly comprises a body 1, a hydraulic pressure plunger pump, a hydraulic oil pump, a main clamp frame component, an assistant clamp frame component, a jack support component 29, a following position shield component 17 and a leverage force application mechanism. The invention is applicable to straightening pendulous railhead in mine, and is also applicable to other fields. The hydraulic pressure railhead straightener is one of indispensable instruments in orbit standardization safety operation in mine, which is safe, labor-saving, effective and portable when operation is carried out on site.

Description

[0001] Field [0002] The invention relates to an on-site straightening method of a drooping rail head and a hydraulic rail head correction machine thereof. The invention is not only applicable to on-site straightening of drooping deformed rail heads in mine shafts, but also applicable to on-site rectification of drooping deformed rail heads in other fields Straightening. Background technique [0003] Before 1995, it was impossible to carry out on-site alignment work for the sagging deformation of the rail head in the underground mine, and the accidents of mine cars falling off the track and overturning caused by this were not uncommon. [0004] Before the hydraulic rail head correction machine produced by Shuanghu Mine Hydraulic Machinery Factory in Xinghua City, Jiangsu Province was put into use, to carry out on-site alignment work on the sagging deformation of the rail head in the mine, the deformed rail had to be removed from the sleeper and used The original method of bu...
