Embodiment 1

[0189] In this example, the frame adopts a double-axle structure with a wheelbase of 6000mm, a gauge of 1435mm (standard gauge), and a wheel diameter of 840mm. It is equipped with a Cummins NTC290 engine and a Fuller RT-11509C gearbox. 50-100Km / h. The wheel position is obtained from the mileage signal output by the gearbox, and the moving distance L can be accurately calculated through the wheel rotation angle (ω) and the number of cycles. Angle measurement adopts LE-60 high-precision inclinometer from Shaanxi Aerospace Great Wall Measurement and Control Co., Ltd. The measurement range of E-60 is ±15 degrees, the resolution is ±0.001 degrees, and the output speed is 1-5 times / second.

[0190] When operating, first set one end as a fixed starting point and read out the initial angle, and move the frame along the track at a constant speed to the first point under the control of the power device (the moving distance of each frame is the same and does not exceed the wheelbase of ...

Abstract

The invention discloses an automatic track settlement measuring device and method based on angle measurement. The device comprises a walking system, a measuring system and a collecting, computing and storing system. The walking system is used for providing a carrying platform and walking power in the testing process. The measuring system is used for carrying out settlement measuring point positioning and angle measuring. The collecting, computing and storing system is used for sampling measuring point positioning information and angle measuring information and carrying out computing and storing with the format according to the set rule. The walking system is arranged on a track through walking wheels and advances with the constant speed along the track. The measuring system and the collecting, computing and storing system are connected through a data transmission cable and are arranged on a car frame platform of the walking system. The automatic track settlement measuring device and method based on angle measurement are easy and convenient to operate, fast in test, high in practicality and capable of being widely applied to automatic continuous tests on the track settlement in the track project.

Description

technical field [0001] The invention relates to an automatic measurement device and method for rail settlement based on angle measurement. Background technique [0002] In the existing technology, traditional level gauges, total stations and other instruments are still mostly used for track settlement monitoring. The above-mentioned methods are mature in equipment and equipment, but labor-intensive and slow in testing speed, which greatly interfere with construction operations or line operations, especially in tunnels, etc. In a similar closed underground space, due to insufficient light, the test accuracy is difficult to guarantee. In recent years, with the rapid development of electronic technology, many scientific and technological workers have also developed a variety of indirect measurement products for the above defects, such as single-point settlement gauges, static levels, etc., but these products still have relatively large limitations, especially This type of prod...
