Detection method and detection device for traction of point switch between turnout point rail and stock rail

Abstract

The invention discloses a detection method and a detection device for traction of a point switch between a turnout point rail and a stock rail. The detection device comprises a detector consisting of a shell, a liquid crystal display screen, number keys and a data processing board, and is characterized in that a pressure sensor circuit board is arranged in an iron plate groove at the middle portion of an iron plate handle, and two ends of a data signal line are respectively connected between a data processing lead interface and an iron plate lead interface; an emergency dismounting step and a test iron plate pressed between the turnout point rail and the stock rail are sequentially fixed at the bottom end of the iron plate handle, a pressure sensor is fixed in a pressure sensor groove in the test surface of the test iron plate, and the pressure signal line of the pressure sensor is connected with the input end of the pressure sensor circuit board in the iron plate groove through a sensor signal line hole. According to the detection method and the detection device, the traction of the power-driven (hydraulic) point switch can be timely learned during ordinary maintenance. The detection method and the detection device have the advantages being capable of automatically detecting traction of the railway point switch between the turnout point rail and the stock rail, accurate and reliable in detection result and convenient to test.

Description

technical field [0001] The invention relates to railway equipment, in particular to a detection method and a detection device for the traction force of a switch machine between a switch point rail and a basic rail. Background technique [0002] The railway turnout is composed of a basic rail, a switch rail and a sliding bed plate supporting the switch rail. The switch rail can slide on the sliding bed plate under the traction of the switch conversion equipment. When the switch is closed, the switch rail on the other side is separated from the basic rail on the same side, and the line opens in one direction; when the switch rail slides in the other direction under the traction of the switch conversion equipment, the switch rail on the other side slides to the basic rail on the same side. When the rails are closely attached, the sharp rail on this side is separated from the basic rail on the same side, and the line is opened in the other direction, thus realizing the reversing...

Problems solved by technology

The "skylight" needs to be repaired for each test, which has a great impact on transportation

Because it is very inconvenient to test like this, the actual traction force of the electric (hydraulic) switch machine of the AC motor has not been tested for a long time, and the large and small changes of the traction force cannot be grasped
