Description
Technical Field
The utility model belongs to the technical field of switch action synchronism inspection and specifically relates to a switch synchronism detecting system is pull to portable multimachine multiple spot.
Background
In recent years, with the large-scale construction of high-speed railways and passenger dedicated lines in China and the comprehensive development of speed acceleration of ordinary railways, large-size multi-machine traction turnouts such as three-machine traction, four-machine traction, five-machine traction and nine-machine traction turnouts are put into use in large quantities. The multi-machine traction turnout is provided with a plurality of traction switch machines which are arranged at the point of the turnout switch rail; for movable point rail switches, a switch machine is also installed at the point rail. The switch machine control unit is responsible for sending commands to all switch machines, ensuring the action consistency of all the switch machines, and ensuring the simultaneous unlocking, simultaneous rotation, simultaneous locking and combined action of all the switch machines. Therefore, multi-machine traction synchronization becomes an important problem in the research and the application of turnouts.
If the switch machines are inconsistent in operation, the stress of each switch machine is uneven, and the current of the switch machine which is operated first is overlarge and exceeds the load, so that the switch machine is damaged. In the practical application of the turnout, the problems of uneven track bed, deformation of turnout structure and installation of a switch machine are caused, and the phenomenon that the switch machine cannot act consistently is easy to happen after long-term running and application.
At present, the method for checking the synchronism of the turnout actions generally adopts the monitoring of the current and the voltage of a switch machine and further calculates the actual power.
In fact, after the switch machine completes the actions of starting, unlocking, lost motion of the outer locking structure and the like, the switch machine action rod starts to drive the track to rotate, namely the actual turnout rotates.
In the existing switch machine monitoring equipment, switch machine current exists in the switch machine starting, unlocking process, external lock idle motion and other time and can be recorded as the switch machine action, so that the existing switch machine monitoring equipment cannot truly reflect the data change of the contact quantity and the repulsion quantity in the switch process of the repulsion switch point and the contact switch point in the actual rotation process of the turnout.
After the railway turnout is laid and the combined renovation operation of the turnout is completed by the engineering and electrical department, the real condition of the synchronism of the point switch can not be obtained only by measuring the size of the turnout installation structure and the current value of the point switch.
In practical use, railway operators can obtain more comprehensive assessment on turnout health conditions by comprehensively analyzing a current change curve output by the existing switch machine monitoring equipment and a density/repulsion change curve output by the equipment in the turnout switching process, and can more clearly and clearly adjust the problem turnout
At present, an effective device for conveniently and rapidly checking the synchronism of a multi-traction point switch machine on site is lacked in the practical application of a railway unit.
