specific Embodiment approach 1

[0035] Such as figure 1 and figure 2 , The recursive railway track detection vehicle includes a mechanical structure part, a control and display part (9), a data acquisition part (11), a sensor and a power supply (7). The power supply (7) is connected to the sensor and the data acquisition part (11) to supply power to the detection vehicle. The sensor is connected with the signal of the data acquisition part (11) and the control and display part (9), and is installed on the mechanical structure part, and the sensor includes six displacement sensors (5) and two rotation angle sensors (12). The data collection part (11) collects the sensor signals. The control and display part (9) receives the data from the data acquisition part (11) for calculation, stores the measurement result data, and displays the measurement result.

[0036] The mechanical structure part is composed of two reference trolleys (1) and the trolley to be tested (4) with the same structure connected upside ...

specific Embodiment approach 2

[0041] The detection method used for the recursive railway track detection vehicle is as follows:

[0042] (1) Detection method of track height and level (height difference between two tracks)

[0043] Such as Figure 4 As shown, in the measurement process, the three points on the surface of the body directly above the three road wheels (3) of the reference trolley (1) are used as reference points, and the height of the reference point is expressed as J 1 、J 2 、J 3 . Take the three points on the surface of the vehicle body directly above the three traveling wheels (3) of the trolley (4) under test as the measurement points, and the height of the measurement point is expressed as h 1 、h 2 、h 3 . The wheel base of two traveling wheels (3) on the same track on the benchmark dolly (1) is 2L.

[0044] Before the measurement, the recursive railway track inspection car must be placed on the track (27), accurately measure the initial height of the reference point relative to t...

Embodiment 1

[0082] The power supply (7) adopts a dry-charged lead storage battery, and provides a regulated DC power supply to the sensor and the data acquisition part (11) after being processed by a voltage-stabilizing circuit. A part of the cable is placed in the cantilever measuring rod (8), and the rest is fixed on the reference trolley (1) and the trolley under test (4).

[0083] The displacement sensor (5) adopts a grating micrometer sensor with a range of 10mm and an output of 50 pulses per millimeter, and outputs 200 pulses per millimeter after frequency division by the circuit of the data acquisition part (11). The angle sensor (12) adopts a photoelectric encoder that outputs 3000 pulses per revolution.

[0084] The data acquisition part (11) adopts a multi-channel data acquisition circuit, a 4-fold frequency circuit, a single-chip microcomputer and a PC interface circuit, and a single-chip microcomputer to realize data collection, and the circuit board is fixed in a metal shell ...

Abstract

The invention discloses a recurrence railway detecting vehicle and detecting method, which is characterized in that: two same reference small vehicles and detected small vehicle via connecting bar are inversely connected to form the frame of detecting vehicle, while the small vehicle is formed by three-point support; the support is arranged with walking wheels; the inner side of rail is contacted with small wheels, a rail surface distortion measurer, a displacement sensor, a suspension measuring rod, a tension device, a corner sensor and a control-display part, which uses the recurrence method to process dynamic continuous measure on the height, horizontal level, rail direction, rail distance and rail surface distortion of railway, with high detecting accuracy, quick speed, simple structure, lower cost, and the application for self-detection and daily maintenance.

Description

technical field [0001] The present invention relates to a kind of equipment and detection method for the installation quality detection of railway track and daily line maintenance detection, specifically a recursive railway track detection vehicle and detection method, including the smoothness of the railway track, that is, the height, The inspection vehicle and inspection method are used to inspect five geometric elements such as level, rail direction, gauge, and rail surface distortion. Background technique [0002] The smoothness test of the railway track is a basic item in the track inspection, including the measurement of five elements such as the height, level, track direction, gauge, and track surface distortion of the two rails. Whether these elements are correct or not is directly related to the safety of railway traffic. [0003] Poor track smoothness will cause greater dynamic action on the contact surface of the wheel and rail, accelerate the wear and fatigue da...
