Embodiment Construction

[0027] The present invention will be further described now in conjunction with accompanying drawing.

[0028] see Figure 1 to Figure 6 , Figure 1 to Figure 6 Shown is the first embodiment of the present invention, which is a "double-track" semi-automatic rail grinding machine, which can grind two side-by-side rails at the same time; it mainly includes a rail fixing platform, a translation platform and several grinding components. This embodiment is used on the construction site of railway engineering site construction, and its grinding and shaping object is a steel rail of 60Kg grade.

[0029] Among them, the rail fixed platform is erected and horizontally fixed on two side-by-side steel rails, and the horizontally movable translation platform is connected with the rail fixed platform through a sliding mechanism; there is a slide between the rail fixed platform and the translation plate to realize the horizontal movement of the translation platform. mechanism.

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 kind of semi-automatic equipment for grinding the welding residue of rail expansion joints, in particular to a semi-automatic rail grinding machine. Background technique [0002] Traditional steel rails generally have expansion joints to cope with 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 traditional rails is welded by using thermite reaction, so that there is no expansion joint between rails , can effectively improve the stability and speed of the train; reduce the noise between the wheel and the rail; eliminate the impact force of the joint, reduce line damage, save raw materials; increase the comfort of passengers. [0003] Seamless rails require welding. After welding, the welding residue will leave protrusions on the two adjacent rails, which need to be removed by grinding...
