Abstract
The utility model provides a monitoring device for the notch of a switch machine. The monitoring device comprises a main indication lever, an auxiliary indication lever, a node seat and a sensor, wherein, the main indication lever is connected with the auxiliary indication lever, the node seat is fixed on the auxiliary indication lever, two grooves are formed on the main indication lever, a lug boss is formed between the two grooves, the sensor is fixed on the lug boss on the main indication lever through a mounting frame, a mounting hole is formed on the auxiliary indication lever, and a hole is formed on the mounting frame and in a position corresponding to the mounting hole on the auxiliary indication lever. Further, the sensor is an inductance type displacement sensor. The position variation of the notch of the indication lever is monitored by the sensor above the lug boss on the main indication lever, a sensor target is not longer required to be mounted on the main indication lever, so as to ensure the normal running of the switch machine; and the inductance type displacement sensor is used, the sensor is not in contact with the lug boss, the volume is small, the accuracy is high, and the stability is excellent. Therefore, the accuracy of the monitoring device is ensured. The monitoring device provided by the utility model has the advantages of simple structure, convenience in maintenance, low cost and the like.
Description
Technical field
The utility model belongs to the monitoring device field of railway switch, especially relates to a kind of switch machine breach monitoring device.
Background technology
The track switch conversion equipment is the railway transportation fundamental equipments, and it is to guarantee railways train operation research content that the turnout work state is monitored always.The variation of switch machine gap position has directly reflected the mode of operation of railway equipment track switch; Monitoring switch machine indication notch position can make service personnel in time understand the variation tendency of track switch state in real time, finds potential problem; The preventative state of realization track switch relevant device is repaiied; Prevent trouble before it happens, therefore simple efficient real time monitoring gap position changes, and is the necessary condition that guarantees traffic safety.If switch machine indication notch position instability or gap position skew are excessive, then can influence the normal use of track switch equipment, therefore check the variation of switching machine indication rod breach, be one of important content of daily attention.
Directly monitoring switch machine indication rod notch is difficult to accomplish; Usually way is an indirect monitoring; Promptly monitor indication rod and put variation with respect to the node seat; The general change in location that all adopts sensor monitors indication rod object, and the installation targets thing can influence the normal use of switch machine on indication rod, monitoring breach side-play amount that can not correct and effective.
Summary of the invention
The problem that the utility model will solve provides a kind of switch machine breach monitoring device of effective monitoring breach side-play amount.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of switch machine breach monitoring device, comprise principal representation bar, secondary indication rod, node seat, sensor, and the principal representation bar is connected with secondary indication rod; The node seat is fixed on the secondary indication rod; The principal representation bar is provided with two place's grooves, forms boss in the middle of two grooves, and sensor is fixed on the boss of principal representation bar through mounting bracket; Secondary indication rod is provided with mounting hole, and the cooresponding position of mounting hole on mounting bracket and the secondary indication rod is provided with the hole.
Further, said sensor is an inductive displacement transducer.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; The indication rod gap position changes through the sensor that is positioned at principal representation bar boss top monitors; Do not need sensor installation object on the principal representation bar again, guarantee the normal operation of switch machine; Use inductive displacement transducer, this sensor does not contact with boss, and volume is little, and precision is high, good stability, and this has just guaranteed the particularity of the utility model.The utility model uses convenient; Have simple in structure, easy to maintenance, advantage such as tooling cost is low.
Description of drawings
Fig. 1 is the simple structure scheme drawing of a kind of switch machine breach monitoring device of the utility model
Fig. 2 is the rough schematic of principal representation bar and principal representation bar and sensor relative position
Among the figure:
1, principal representation bar 2, secondary indication rod 3, node seat
4, mounting bracket 5, boss 6, sensor
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of switch machine breach of the utility model monitoring device comprises principal representation bar 1, secondary indication rod 2, node seat 3, sensor 6, and principal representation bar 1 is connected with secondary indication rod 2; Node seat 3 is fixed on the secondary indication rod 2; Principal representation bar 1 is provided with two place's grooves, forms boss 5 in the middle of two grooves, and sensor 6 is fixed on the boss 5 of principal representation bar 1 through mounting bracket 4; Secondary indication rod 2 is provided with mounting hole, and the cooresponding position of mounting hole on mounting bracket 4 and the secondary indication rod 2 is provided with the hole.
In order further to optimize the performance of the utility model, said sensor 6 adopts inductive displacement transducer.This sensor 6 does not contact with boss 1, and volume is little, and precision is high, good stability, and this has just guaranteed the particularity of the utility model.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
