Embodiment Construction

[0028] The present invention will now be further described with reference to the drawings.

[0029] See Figure 1 to Figure 6 , Figure 1 to Figure 6 Shown is the first embodiment of the present invention, which is a "dual track" semi-automatic rail grinding machine, which can grind two side-by-side rails at the same time; it mainly includes a rail fixed platform, a translation platform and several grinding components. This embodiment is used on the construction site of a railway engineering site, and the object for grinding and shaping is a 60Kg rail.

[0030] Among them, the rail fixed platform is erected and fixed horizontally on two side-by-side rails, and the horizontally movable translation platform is connected to the rail fixed platform through a sliding mechanism; a sliding platform is provided between the rail fixed platform and the translation plate to realize the horizontal movement of the translation platform mechanism.

[0031] See Figure 4 The rail fixed platform i...

Abstract

The invention relates to a semi-automatic rail grinding machine comprising a steel rail fixing platform, a translation platform and a plurality of grinding assemblies. The steel rail fixing platform is arranged and horizontally fixed on a steel rail; the translation platform capable of horizontally moving is connected with the steel rail fixing platform via a sliding mechanism; a plurality of grinding assemblies are arranged on the translation platform; and grinding heads of the grinding assemblies pass through openings on the steel rail fixing platform and the translation platform to be respectively aligned to a plurality of to-be-grinded rail surfaces of the steel rail in a staggered way. All surfaces of welding parts of the well-paved seamless steel rail are grinded by the grinding assemblies installed in a staggered way; human labor intensity can be reduced due to the semi-automatic design, and work efficiency and economic benefits can be improved; the semi-automatic grinding machine is simply structured and has novel design and small equipment size; the grinding machine can be conveniently carried, thereby being easily promoted and used; and the semi-automatic rail grinding machine can work on the well-paved steel rail, so troubles of transportation and construction can be avoided and rail paving speed can be greatly improved.

Description

[Technical Field] [0001] The invention relates to a semi-automatic equipment for polishing the welding residual material of the expansion joint of a steel rail, in particular to a semi-automatic rail grinding machine. [Background technique] [0002] Traditional steel rails are generally equipped with expansion joints that respond to thermal expansion and contraction. However, with the continuous development of railway transportation, many high-speed railways have adopted seamless rail technology—that is, the gap between the traditional rails is welded by thermite reaction, so that there is no longer an expansion joint between the rail and the rail. , Can effectively improve the stability and speed of the train; reduce the noise between the wheels and the rail; eliminate the joint impact, reduce line damage, save raw materials; increase passenger comfort. [0003] Seamless steel rails need to be welded. After welding, the welding residual material will leave protrusions on the two...
