Abstract

The invention discloses a test platform for a steel-rail milling and grinding machine. The test platform comprises a test platform frame, wherein the bottom of the test platform frame is mounted on the test platform by a first adjusting device which can adjust the inclination of the test platform frame; the steel-rail milling and grinding machine is arranged on a cross beam of the test platform frame; a guide rail is arranged on the test platform below the steel-rail milling and grinding machine; a guide rail vehicle driven by a low-voltage power supply is mounted on the guide rail; and a steel-rail test piece is arranged on the guide rail vehicle opposite to the working end face of the steel-rail milling and grinding machine by a second adjusting device which can adjust the rail distance of the steel-rail test piece. The test platform provided by the invention is complete in function, simple in structure and low in cost, and provides a powerful test technical support for the equipment debugging and study of the steel-rail milling and grinding machine.

Description

technical field

[0001] The invention relates to a test platform, in particular to a rail milling and grinding vehicle test platform. Background technique

[0002] High-speed railways, subways, and intercity trains are developing rapidly in my country, and strict requirements are placed on the surface roughness and smoothness of rails. The milling and grinding machine is used to hang the milling machine and the grinding machine upside down on the bottom of the train, and the train drives the milling and grinding machine forward. First, the forming milling cutter wheel is used for high-speed milling, and then the wide grinding wheel is used for forming grinding to eliminate milling processing errors and forming interface water chestnuts. , to improve the surface roughness and smoothness of the rails, this milling and grinding car has gradually replaced the rail grinding train as the main means of railway rail repair. Due to the limitation of the railway carrying capacity, the...

Embodiment Construction

[0013] A specific implementation of a rail milling and grinding car test bench will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , 2 , 3. A rail milling and grinding car test bench includes a test platform frame and a feeding device. The test platform frame includes a beam 1, a support 2, a side support frame 8 and a first adjustment pad iron 9. The feeding device includes a rail test piece 4, a weight 5, a guide rail car 7 and a second adjustment pad iron 6.

[0015] The rail milling and grinding vehicle 3 is hung upside down on the beam 1, the first adjustment pad 9 is fixed to the ground through anchor bolts, the support 2 is installed on the first adjustment pad 9, and the rail test piece 4 is fixed to the second adjustment pad through a pressure block. On the pad iron 6, the second adjustment pad iron 6 is integrally fixed on the guide rail car 7.

[0016] The rail milling and grinding car 3 has three kinds of wo...
