Medium-sized grinding wagon for railway work section

Abstract

The invention provides a medium-sized grinding wagon for a railway work section. A power bogie and a non-power bogie are arranged on the lower end surface of a frame; a grinding trolley used for grinding the surface of a steel rail is arranged between the power bogie and the non-power bogie. The grinding trolley is connected with a grinding position adjusting mechanism which is arranged on the lower end face of the frame and used for adjusting the height and the grinding direction of the grinding trolley, and a power system arranged on the upper end face of the frame provides power for the grinding position adjusting mechanism, the power bogie and the grinding trolley. The grinding position adjusting mechanism connected with the grinding trolley and used for adjusting the height and the grinding direction of the grinding trolley is arranged on the lower end face of the frame; the grinding trolley has the up-down freedom degree and the grinding trolley has good operation performance ona curve, short-distance operation points and turnout related areas, so that the grinding capacity and the grinding quality of the grinding trolley are improved, the steel rail grinding difficulty is lowered, limitation is small, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of railway maintenance equipment, and in particular relates to a medium-sized grinding vehicle used for railway construction sections. Background technique [0002] In order to eliminate rail defects, improve the smoothness of the rail surface, prolong the service life of the rail, reduce the running performance of the train, improve the comfort of the train, and ensure the safe operation of the train, it is necessary to grind the railway rail frequently; at present, the rail grinding mainly adopts large grinding equipment and small grinding There are two ways of tools. Large-scale grinding equipment is mostly 96 grinding heads, 48 ​​grinding heads or 20 grinding heads rail grinding trains. The grinding trains are usually composed of multiple cars, with good grinding quality and high efficiency. The maintenance cost is high, and the preparation and maintenance time is too long, which is only applicable to th...

Problems solved by technology

[0002] In order to eliminate rail defects, improve the smoothness of the rail surface, prolong the service life of the rail, reduce the running performance of the train, improve the comfort of the train, and ensure the safe operation of the train, it is necessary to grind the railway rail frequently; at present, the rail grinding mainly adopts large grinding equipment and small grinding There are two ways of tools. Large-scale grinding equipment is mostly 96 grinding heads, 48 ​​grinding heads or 20 grinding heads rail grinding trains. The grinding trains are usually composed of multiple cars, with good grinding quality and high efficiency. The maintenance cost is high, and the preparation and maintenance time is too long, which is only applicable to the long-distance main line section, while the temporary repair and grinding operation points of public works are usually short in distance, and the number of disease points is large but scattered widely. The cost of using large-scale grinding equipment will cause manpower Waste of material resources, even large grinding equipment in small radius curves and turnout related areas cannot be operated, the efficiency of using small grinding tools is low, the quality of grinding is difficult to guarantee, the labor investment is large, and the management cost is high. It is increasingly difficult to meet the needs of current railway development. ; The patent No. is 201410028628.2, and the patent name is called in the patent document of " subway rail grinding car with self-powered power ", discloses a kind of rail grinding car, although the vehicle frame lower end face between power bogie and non-power bogie is also designed There is a grinding device, but this grinding device is only suitable for the long-distance main line section, and cannot realize the rail grinding of the operating point on the curve and the short distance and the relevant sections of the turnout. Therefore, it is necessary to improve the above problems
