Description

Novel limit measurement method for railway I-shaped steel pole tower
Technical Field
The invention relates to a novel limit measurement method of a railway I-shaped steel pole tower, namely an I-shaped steel wire laser ranging method.
Background
Delimitation refers to the line of dimension of the contour that is prescribed for the rolling stock and the buildings and equipment adjacent to the track that must not be exceeded in order to ensure the safety of the rolling stock running on the railway track, preventing the rolling stock from hitting the buildings and equipment adjacent to the track.
At present, most building boundary measuring methods are manual measuring, and main measuring tools are a platform limit measuring scale and a digital display type measuring instrument. The method has the disadvantages that a measurer needs to go down to operate, a plurality of persons need to go down to measure the station track at the same time, the measurement needs to be completed within the time of the operation of the railway maintenance skylight, and the limited operation time of the maintenance skylight needs to be reported in advance for one week, so that the huge workload of the operator for completing the measurement of the building clearance along the railway on time is hardly met. Building limit data needs to be updated in time, and if the building limit data cannot be updated regularly, great potential safety hazards are caused to the driving transportation safety. The existing measuring mode is troublesome and labor-consuming, the working efficiency is lower, and the error is large.
In order to solve the problems in the measuring process, a set of novel H-shaped steel pole tower clearance measuring method is researched, the method can enable personnel and equipment to finish measuring operation without going down, and the method considers the difference between an actual abrasion track and a theoretical track to be more accurate and can be applied to practice.
Disclosure of Invention

Through using laser range finder transmission laser to carry out the clearance measurement to the building along the line of track, equipment testing personnel can remotely control the small rail car that traveles on the track, realizes that laser range finder transmits laser and signal acceptance to the building along the line of railway, and rethread internal design algorithm just can be accurate reachs railway clearance data, scans the I-steel shaft tower and obtains clearance measured data and show on the display screen to can convey intelligent Mobile terminal through bluetooth transmitter. And comparing the current building limit with the specified platform building limit to judge whether the current building limit exceeds the danger range. In this way, the measurement of the building clearance along the rail is very accurate, and the labor capacity of railway workers is greatly increased.
The technical scheme adopted by the invention is as follows: the novel method for measuring the clearance of the I-shaped steel pole tower is characterized by comprising a trolley chassis, a line laser ranging sensor, wheels, a main body support, a servo motor, a single chip microcomputer, a display screen, a Bluetooth transmission device, an intelligent mobile terminal, a line laser sensor arranged on a support frame, the support frame arranged on the trolley chassis, a tester remotely controlling a trolley to move along a rail on the rail, so that a measuring point of the line laser sensor is right opposite to the I-shaped steel pole tower, clearance measuring data obtained by scanning the I-shaped steel pole tower are displayed on the display screen, and the clearance measuring data can be transmitted to the intelligent mobile terminal through a Bluetooth transmitter.
The chassis of the trolley is made of metal, and four wheels are arranged on the chassis;
the main body bracket is provided with a turntable;
the line laser ranging sensor is arranged on the turntable and can rotate freely;
the line laser ranging sensor can measure data of the distance from the I-beam to the center line of the railway, and the measured data are used for obtaining the distance between the I-beam and the center line of the railway through an internal algorithm;
the display screen can display the distance between the I-steel and the railway center line obtained by the internal algorithm;
the Bluetooth transmission device can be transmitted to the intelligent mobile terminal by the data of the display screen;
the intelligent mobile terminal can judge whether the I-steel limit exceeds a danger range through analysis.
Compared with the traditional building clearance distance measurement method, the invention has obvious advantages: 1. the test speed is very quick by controlling the trolley to run on the tested track, and the obtained data is very accurate. The tester can finish the measurement of the building clearance along the railway in a short time. 2. By adopting the method, a measurer does not need to go down to measure, and can directly carry out remote measurement operation on the laser range finder indoors, so that the test time and the test working period are greatly reduced.
