Abstract

The invention discloses railway track detection equipment. The equipment comprises two detection vehicles which are used for conducting multiple detective operations on railway tracks and arranged on two abreast railway tracks in a gliding mode, a cross girder expansion device which is flexibly mounted between the two detection vehicles and in a ligature direction of the two detection vehicles, and used for connecting the two detection vehicles and adapting to gauge changes between the two railway tracks, wherein the cross girder expansion device includes a long shaft extending in the ligature direction of the two detection vehicles, and both ends of the long shaft are rotatably connected with one group of flexible component of the cross girder respectively; two groups of the flexible components of the cross girder are arranged symmetrically to the midpoint of a lengthwise direction of the long shaft, and each of the flexible components of the cross girder is connected to a corresponding detection vehicle in a detachable mode. The railway track detection equipment has the advantages of being easy to carry, convenient to push forward during detection, simple in operation during detection, and the measuring basis of the railway track detection equipment is sole, therefore the influences of mechanical errors are able to be eliminated, and the accuracy of measurement is improved extremely.

Description

technical field

[0001] The invention relates to the technical field of railway measurement, in particular to a railway track detection device. Background technique

[0002] With the rapid development of my country's railways, the speed of trains is also increasing, and at the same time, the problem of track structure diseases is becoming more and more serious, especially the smoothness of high-speed railway tracks directly affects the safe operation of high-speed trains. In order to meet the safety and comfort requirements of train operation, it is necessary to regularly detect track structural defects such as the geometric state of the track, damage and wear of the rail. Small portable detection equipment is widely used in the field of railway track measurement due to its advantages of portability and high efficiency.

[0003] When measuring, the track gauge changes, especially the widening of the track gauge in the curved section, which changes the measurement benchmark o...
