Description
Technical Field
The invention belongs to a turnout conversion equipment auxiliary system in the field of rail transit, and relates to a method for judging a switch machine action rod conversion jamming fault mode.
Background
The switch machine is used for switching and locking turnouts, when the switch machine is blocked by action rod switching, the function of switching turnouts is invalid, and statistical data show that the turnouts can not be switched due to the blocked action rod switching of the switch machine is higher in turnout fault rate due to various reasons.
When the action rod of the switch machine is switched to be blocked and can not be switched to the turnout, a train can not pass through the turnout according to a plan, and then the running is delayed, generally, maintenance personnel is required to perform emergency temporary treatment, delay is reduced as much as possible, economic loss is reduced, and social influence is reduced.
The specific meanings of the characters and symbols in the following description are described in the detailed description of the invention.
During the extension of the switch machine action rod or the retraction of the action rod,
when the delta S is less than or equal to the delta, the point switch is in the internal unlocking process;
when delta is more than delta S and less than or equal to L Solution (II) When the switch machine is in the process of driving the outer lock to unlock;
when L is Solution (II) ＜ΔS≤L-L Lock with a locking mechanism When the switch machine is in the process of driving the outer locking and the turnout movable part to carry out conversion;
when L-L Lock with a locking mechanism When the angle is less than delta S and less than or equal to L-delta, the point switch is driven to be locked outwardsIn the locking process;
when L-delta < delta S, the switch is in the locking process.
If the turnout is an internal locking system, no external locking unlocking and locking process exists, no matter in the process of extending the action rod of the point switch or in the process of pulling the action rod,
when the delta S is less than or equal to the delta, the point switch is in the internal unlocking process;
when delta S is more than delta S and less than or equal to L-delta, the point switch is in the process of driving the movable part of the turnout to carry out conversion;
when L-delta < delta S, the switch machine is in the locking process.
Therefore, the state of the switch machine can be judged by accurately measuring the displacement of the action rod of the switch machine and combining the specific structural parameters and turnout characteristic parameters of the switch machine according to the current stroke of the action rod, and then the blocking reason of the action rod is analyzed and judged according to the state of the switch machine when the action rod is blocked or blocked and combining other information.
More specific reasons for the jamming or jamming of the action rod conversion need to be refined on the basis of the above, for example, the specific reasons that the conversion locking mechanism in the switch machine cannot be unlocked can be subdivided into the specific reasons that the conversion locking mechanism is seriously worn or damaged, the motor loses power and the like, and more detailed information is needed to clearly identify the specific reasons causing the fault.
When the working state of the switch machine action rod during blocking or jamming is determined or the fault mode is specified, the fault position can be determined, the maintenance position can be defined, the fault reason can be analyzed as soon as possible by combining other information, the solution can be determined, the maintenance personnel can conveniently and quickly remove the fault, and the fault processing time can be shortened.
