An adjustable plug for top adjustment of turnout rail

Abstract

The invention discloses an adjustable ejector head for turnout steel rail jacking adjustment. The ejector head comprises a middle ejector head, an upper ejector head and a lower ejector head; the headend face of the middle ejector head is arc and used for making contact with a rail waist of a steel rail. The upper ejector head is arranged above the middle ejector head; the upper ejector head is slidably connected with the middle ejector head; the upper ejector head is pushed by an upper pushing device to slide on the middle ejector head; the upper ejector head is positioned on the middle ejector head by an upper positioning device; the head of the upper ejector head is used for making contact with a rail head of the steel rail; the lower ejector head is arranged below the middle ejector head and connected with the middle ejector head in a sliding mode; the lower ejector head is pushed by a lower pushing device to slide on the middle ejector head, the lower ejector head is positioned on the middle ejector head through a lower positioning device, and the head of the lower ejector head is used for making contact with the rail bottom of the steel rail. The adjustable ejector head canmake contact with the rail head, the rail waist and the rail bottom of the steel rail at the same time during jacking adjustment, so the turnout steel rail is stressed evenly, and the requirements forthe straightness of the working edge and the straightness of the rail head of the turnout steel rail are met.

Description

technical field [0001] The invention relates to the technical field of turnout rail processing equipment, in particular to an adjustable plug used for top adjustment of turnout rails. Background technique [0002] With the rapid development of my country's economy, the continuous improvement of railway transportation construction, and the continuous increase of the speed of high-speed rail, my country's demand for turnout rails is increasing, and higher requirements are put forward for the quality of turnout rails. Turnout rail is a kind of line connection equipment that enables locomotive vehicles to transfer from one track to another. It is also one of the weak links of the track. It is usually laid in large quantities at stations and marshalling yards, and plays an important role in railway lines. Turnout rails need to be top-adjusted during the processing process to form a degree of curvature that meets the requirements of railway laying. At present, in major turnout pro...

Problems solved by technology

Turnout rails need to be top-adjusted during the processing process to form a degree of curvature that meets the requirements of railway laying. At present, in major turnout processing enterprises, most of the turnout rail processing uses top-adjustment equipment, and most of the plugs used for turnout top adjustment are It is a rectangular block. When the turnout is adjusted at the top, the force on the cross section of the turnout will be uneven, which may cause the straightness of the working side of the turnout and the straightness of the rail head to not meet the national regulations, and even lead to the breakage of the turnout. Therefore, in the turnout rail In the field of processing, there is an urgent need for an adjustable plug that can make the rail head, rail waist, and rail bottom of the turnout evenly stressed.
