Abstract
The utility model relates to the field of railway turnouts, in particular to a railway turnout close contact inspection mechanism which comprises a switch rail fixture, a test target fixing block, a test target, a sensor support and a stock rail fixing clamp, wherein the switch rail fixture is connected with the test target fixing block and fixed on two sides of a railway turnout switch rail, the test target is fixed on the test target fixing block through a threaded connection pair, the stock rail fixing clamp is installed at the bottom of the turnout stock rail, the sensor support is fixed on the stock rail fixing clamp through the threaded connection pair, and the sensor is installed inside the sensor support. The utility model is arranged on the switch stock rail and the switch rail in a matching way through the special fixture, avoids punching the steel rail, automatically monitors the close contact state between the railway switch rail and the stock rail in a static state through the sensor, and does not influence the switch conversion.
Description
Technical Field
The utility model relates to the technical field of turnout snow melting, in particular to a railway turnout close contact inspection mechanism.
Background
According to the regulation of "signal maintenance rule and technology standard" of railway department, when the turnout is positioned or reversed in static state, "when there is a gap of 4mm or more between the switch rail and stock rail at the centre line of every traction point, the locking mechanism must not lock and turn on the turnout to show".
The present indication source of the fixed and reversed positions of the turnout is that after the indication rod of the point switch moves to the position or reversed position along with the point rail, the rod is used to communicate the circuit contact to complete the task of indicating the fixed and reversed positions of the turnout, or whether the gap between the point rail and the stock rail is required is indicated by whether the gap check column falls down. But the amount of clearance between the point rail and the stock rail cannot be accurately monitored.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the technology and provide a railway turnout joint sealing inspection mechanism, which monitors the clearance value between a switch rail and a stock rail in real time through a sensor.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a railway switch pastes inspection mechanism closely which characterized in that: the device comprises a switch rail clamp, a test target fixing block, a test target, a sensor bracket and a stock rail fixing clamp; the switch rail fixture is connected with the test target fixing block and fixed on two sides of the switch rail of the railway turnout, and the test target is fixed on the test target fixing block through a threaded connection pair; the stock rail fixing clamp is arranged at the bottom of the turnout stock rail, the sensor support is fixed on the stock rail fixing clamp through a threaded connection pair, and the sensor is arranged inside the sensor support.
Preferably, the stock rail fixing clip is provided with a clip slot for fixing the stock rail.
Preferably, the sensor corresponds to a test target.
The turnout stock rail clamp has the beneficial effects that the turnout stock rail clamp is matched with and arranged on a turnout stock rail and a switch rail through a special clamp, so that the steel rail is prevented from being perforated. The sensor is used for automatically monitoring the close contact state of the railway turnout switch rail and the stock rail in a static state, and the turnout conversion is not influenced.
Drawings
Fig. 1 is a schematic structural view of a railway turnout closure inspection mechanism provided by the utility model.
Detailed Description
The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. The utility model provides a close inspection mechanism that pastes of railway switch, includes switch rail fixture 1, test target fixed block 2, test target 3, sensor 4, sensor support 5, stock rail fixing clip 6, switch rail fixture 1 with test target fixed block 2 is connected and fixes in railway switch rail both sides, test target 3 fixes through threaded connection is vice on test target fixed block 2, stock rail fixing clip 6 is installed in switch stock rail bottom, sensor support 5 fixes through threaded connection is vice on stock rail fixing clip 6, sensor 4 installs inside sensor support 5.
In the utility model, the test target 3 is arranged on the switch rail through the switch rail clamp 1 and the test target fixing block 2 and moves along with the switch rail when the switch is pulled. The sensor 4 is fixed on the turnout stock rail through the sensor bracket 5 and the stock rail fixing clip 6, keeps static all the time and monitors the distance between the turnout stock rail and the test target 3 in real time. When the turnout is pulled in place, the difference value between the measured distance value and the initial installation time value is compared, and the difference value is the size of the gap between the turnout switch rail and the stock rail.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
