Embodiment 1

[0085] 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.

[0086] 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 a track sedimentation measuring device and method based on angle measurement. When operation is conducted, firstly, one end is set as a fixed starting point, the initial angle is read, a frame moves along a track at the constant speed to a first point under the control of a power device, and the angle of the first point is read, wherein the frame moves by the same distance each time, and the distance does not exceed the distance between axles of the frame; in this way, operation is conducted on the second point, the third point...the final point, and the initial value is calculated; when operation is conducted again, one end is still set as a fixed starting point, the angle is read, the frame is moved to the first point, and the angle of the first point is read; in this way, operation is conducted at the second point, the third point...the final point, and the measurement value is calculated; the values read two times are calculated, and the numerical values of the same point are compared, and then relative sedimentation of the track can be calculated. The track sedimentation measuring device and method based on angle measurement are low in cost, easy to implement and high in measurement accuracy.

Description

technical field [0001] The invention relates to a track settlement measuring device and a measuring method based on angle measurement. Background technique [0002] In the prior art, there are many methods for track subgrade settlement monitoring, which can be divided into single-point settlement, layered settlement, cross-section settlement and longitudinal section settlement according to the geometric distribution of the measuring points. It can be divided into settlement plate method, electromagnetic settlement instrument, soil displacement meter, inclinometer tube method, static leveling method, hydraulic settlement instrument, fiber grating sensor and satellite remote sensing (high cost and limited accuracy) and other methods. For the existing measurement point layout and measurement method, the measurement point layout has high requirements and heavy workload, especially during long-term monitoring, the maintenance workload is heavy, and the data collection during meas...
