Embodiment Construction
[0013] At present, for the air tightness detection of air pipelines of large-scale road maintenance machinery products, the method often used by technicians is: in the debugging and preparation stage of large-scale road maintenance machinery products, use an air compressor as an external air source to suppress the air pipeline; When the pressure reaches the required pressure, cut off the passage between the air compressor and the air pipeline; check the leak point by listening to (the sound of gas leakage) and brushing soapy water; treat the leak point so that it no longer leaks.
[0014] Once a leak is found in a certain air pipeline, it is necessary to release the pressure in all the air pipelines to deal with the leak point. If the vehicle body or other parts interfere with the tooling when dealing with the leak point, it is necessary to dismantle the pipeline Movement, thereby increasing the labor intensity of the operator, and the overall air pipeline volume is relatively ...

The invention discloses a leakage detection method for air pipelines of a large-sized road maintenance machine product. The method comprises the following steps of: classifying the air pipelines of the large-sized road maintenance machine product according to a schematic diagram of a pneumatic part of the large-sized road maintenance machine product before the air pipelines are assembled; after one class of air pipelines are assembled, detecting the air pipelines of the class by utilizing an air pipeline leakage detection device, and maintaining leakage points; after the leakage detection and maintenance of the air pipelines of the class are finished, assembling the air pipelines of the next class, and repeating the detection and maintenance processes; and detecting and maintaining the rest air pipelines in the same manner to finish the assembly and detection of all the air pipelines of the large-sized road maintenance machine product. According to the air pipeline leakage detection method for the large-sized road maintenance machine product, the air pipelines are classified and detected before being assembled, so that production and debugging cycles can be shortened, and the debugging efficiency can be improved.
Description
technical field [0001] Embodiments of the present invention relate to air tightness detection technology, in particular to a method for detecting air pipeline leakage of large road maintenance machinery products. Background technique [0002] With the rapid development of high-speed, heavy-duty and comfortable railways in our country, in order to ensure the normal operation of trains, it is very necessary to use large-scale road maintenance machinery products to inspect and repair the lines in a planned, systematic and regular manner. At present, the large-scale road maintenance machinery products used in my country mainly include line tamping vehicles, turnout tamping vehicles, dynamic stabilization vehicles, screen cleaning machines, ballast shaping vehicles, rail grinding vehicles, etc. It is particularly important to inspect and maintain each system of these large-scale road maintenance machinery products to make them work normally and safely. [0003] The types of air ...
