Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Examples
A comprehensive turnout detection system comprises a displacement acquisition module, a communication module and a processing module;
the acquisition module is used for acquiring the climbing amount of the stock rail, the transverse moving amount of the stock rail, the climbing amount of the switch rail and the transverse moving amount of the switch rail; in this scheme, collection module sets up to two laser rangefinder sensors.
The communication module is used for transmitting the base rail climbing amount, the base rail transverse moving amount, the switch rail climbing amount and the switch rail transverse moving amount to the processing module;
and the processing module is used for analyzing the running state of the turnout according to the base rail crawling amount, the base rail transverse moving amount, the switch rail crawling amount and the switch rail transverse moving amount.
The distance between the wheels of the train is fixed, so the distance between the rails is also fixed, but the fixed part for fixing the rails is easy to loosen due to the fact that the train runs on the rails for a long time, so that the rails are displaced, particularly at turnouts, if the displacement condition of the rails is not found in time, the derailment phenomenon of the train is easy to occur during rail replacement, and serious safety accidents are caused.
Therefore, in the example, the displacement conditions of the stock rail and the switch rail at the turnout are detected by arranging the acquisition module so as to find the abnormal condition of the turnout in time.
Specifically, in this embodiment, the acquisition module includes a first displacement acquisition module, a second displacement acquisition module, a third displacement acquisition module, and a fourth displacement acquisition module;
as shown in fig. 1, the first displacement acquisition module is disposed on the outer side of the stock rail, and an acquisition port of the first displacement acquisition module faces the stock rail and is used for acquiring the transverse displacement of the stock rail;
the second displacement acquisition module is arranged on the outer side of the stock rail, and an acquisition port of the second displacement acquisition module faces the switch machine support and is used for acquiring the crawling amount of the stock rail;
because the length of stock rails extends for thousands of kilometers, the crawling amount of the stock rails cannot be directly measured through the second displacement acquisition module. And the switch machine support is fixed setting on the stock rail, consequently, in this embodiment, gathers the crawl volume that the goat support reflects the crawl volume of stock rail through the second displacement collection module.
The third displacement acquisition module is arranged on the inner side of the stock rail, and an acquisition port of the third displacement acquisition module faces to the side face of the switch rail and is used for acquiring the transverse displacement of the switch rail;
the fourth displacement acquisition module is arranged on the inner side of the stock rail, and an acquisition port of the fourth displacement acquisition module faces to the end face of the switch rail and is used for acquiring the crawling amount of the switch rail.
After acquisition module acquires stock rail crawling volume, stock rail sideslip volume, switch blade crawling volume and switch blade sideslip volume, climb stock rail volume through communication module, stock rail sideslip volume, switch blade crawling volume and switch blade sideslip volume transmit for processing module, processing module is according to stock rail crawling volume, stock rail sideslip volume, switch blade crawling volume and switch blade sideslip volume judge the state of switch, and when the switch is in abnormal state, alarm operation, specifically the processing procedure as follows:
if the creep amount of the stock rail, the cross-sliding amount of the stock rail or the creep amount of the switch rail is not equal to zero, the processing module performs alarm operation;
and if the transverse displacement of the switch rail is not equal to the preset transverse displacement, the processing module performs alarm operation.
The preset transverse displacement is the maximum displacement of the point rail from the repulsion state to the close contact state or the maximum displacement of the point rail from the close contact state to the repulsion state when the turnout system normally operates.
Further, it is considered that in an actual turnout system, due to the blockage of the installation part or the fixing part, the fourth displacement acquisition module cannot acquire the switch rail climbing amount. Based on this, an extension bracket is added in this embodiment, as shown in fig. 2, one end of the extension bracket is fixedly disposed on the switch rail through a screw, the other end of the extension bracket is exposed out of the switch rail, an axis of the extension bracket is perpendicular to an axis of the switch rail, the fourth displacement acquisition module is fixed on the sleeper, and an acquisition port of the fourth displacement acquisition module faces the extension bracket and is used for acquiring a climbing amount of the switch rail.
In this scheme, through set up the extension support on the switch rail, the indirect switch rail that will extend to the side for there is not the hindrance between fourth displacement collection module and the stock rail, so that fourth displacement collection module can acquire the switch rail amount of crawling.
In addition, if directly install two laser displacement sensor at the track railway roadbed, because train reciprocating motion on the stock rail can lead to two laser displacement sensor to take place the shake to influence data measurement's accuracy, consequently, in this scheme, still design has the fixed bolster, as shown in fig. 3, during the use, at first firmly be fixed in the fixed bolster through expansion bolts on ground with two laser displacement sensor fixed bolster, then on passing through the train, avoid causing the shake of two laser displacement sensor.
Because, the outdoor environment that railway switch was located is abominable, if expose two laser displacement sensor in the environment, the time for a long time can appear muddy or the condition that dust is piled up, also or the muddy splash that the train passed through to bring up falls on two laser range sensor's mirror surface to cause two laser range sensor can not normally work. Based on this, this scheme has designed a protection casing to this special application scene for no matter under the switch rail is in which kind of state, the protection casing homoenergetic is laminated with the switch rail, thereby reduces external foreign matter and spatters the probability that falls on two laser rangefinder sensor mirror surfaces, has strengthened two laser rangefinder sensor's reliability, has prolonged two laser rangefinder sensor's maintenance cycle, reduces the railway and maintains intensity of labour.
Specifically, as shown in fig. 4, in the present embodiment, the protective cover includes a fixed plate 10, a protective shell 11, and a spring 12; the fixed plate 10 is concave, the outer bottom of the fixed plate 10 is fixedly provided with the top of the fixed support, the double-laser ranging sensor is fixedly arranged at the inner bottom of the fixed plate 10, and a probe of the double-laser ranging sensor is opposite to the switch rail and used for measuring the distance between the double-laser ranging sensor and the switch rail; a limiting groove 14 is formed in the outer side surface of the fixing plate 10, a limiting strip 13 is arranged on the inner side wall of the protective shell 11, the limiting strip 13 is arranged in the limiting groove 14, and when the protective cover moves along with the switch rail, the limiting strip 13 slides left and right in the limiting groove 14; one end of a spring 12 is fixed on the fixing plate 10, the other end of the spring 12 is fixed at the left end of the protective shell 11, and the right end of the protective shell 11 is abutted against the switch rail; when the switch rail and the stock rail are in a close contact state, the spring 12 is in a natural state; when the point rail is in a repulsed state from the stock rail, the spring 12 is in a stretched state.
The working principle is as follows: when the point rail abuts against the stock rail, the spring 12 is in a natural state; when the switch rail is separated from the stock rail, because the acting force of the switch rail on the protective shell 11 is greater than the acting force of the spring 12 on the protective shell 11, the protective shell 11 moves outwards under the driving of the switch rail, and the spring 12 is in a stretching state; when the point rail is drawn close to the stock rail, the point rail is separated from the protective shell 11, and at the moment, the protective shell 11 only has the acting force of the spring 12, so that the protective shell 11 moves towards the point rail side under the restoring force of the spring 12 until the spring 12 is in a natural state. Preferably, when the point rail and the stock rail are in a state of being attached to each other, the spring 12 is slightly stretched, so that the contact between the protective shell 11 and the point rail is tighter, and the situation that impurities fall between the protective shell 11 and the point rail to cause inaccurate measurement data is avoided.
