Abstract
The invention belongs to the technology of railroad switch signal detection, and especially relates to a railroad switch point closure sensor. The railroad switch point closure synchronous sensor comprises two parts including a push rod signal area and a magnetically sensitive reed switch signal area, wherein when a push rod in the push rod signal area is pushed, an electrically conductive metallic sheath moves toward a current static current along with the push rod to achieve current conduction; a magnetically sensitive reed switch in the magnetically sensitive reed switch signal area is arranged in a groove in the middle of a base, both the current static current and the magnetically sensitive reed switch are connected with a bottom plate respectively through leads and are respectively connected with a sensing output binding post connected to the bottom plate. The railroad switch point closure sensor has strong high temperature resistance, moisture resistance, vibration resistance, industrial dust resistance and corrosive gas resistance, is extremely suitable for molten iron load in large-scale steel enterprises, railroad signal of slab engine and safety automatic control, and avoids the serious accident of engine derailing caused by erroneous switches.
Description
Technical field
The invention belongs to the railway switch signal detection technique, relate in particular to a kind of railroad switch point closure sensor.
Background technology
The turning to of railway locomotive head, lane change is leaned on is the railroad switch technology: i.e. various switch apparatus on the railway line.The advance of railway switch technology is directly connected to the running efficiency and the safety of railway locomotive.As shown in Figure 1, railway switch mainly is made up of 2 movable switch tracks 21, switch machine 22, track switch light switch 23 etc.Switch machine 22 wherein is mechanicals device of promotion activity switch track 21, and the rail lane change is turned to.Track switch light switch 23 on the parallel rail in both sides is whether detect behind the turn-out track switch track 21 closely connected in parallel rail (Ministry of Railways's standard: its gap must not greater than 4mm).When closely connected gap during greater than 4mm, control box is with regard to drive signal lamp (redness) flicker, prompting trainman block off traffic.
From prior art as can be seen, in case railway switch unwarrantable words of its reliability when turn-out track, consequence is just hardly imaginable.Especially switch machine starts, and has foreign matters such as stone or rail switching not to put in place etc. between switch track and parallel rail, will make track switch being " four open " state (2 parallel rail, 2 movable switch tracks equal four are irrelevant).Meeting quick operated start " track switch light switch " during track switch " four hold ", and drive the other alarming lamp prompt of being in an emergency of rail, the trainman is according to the Warning light sudden stop of being in an emergency.If the influence of driver's absent minded or amblent air temperature, the Warning light of being in an emergency are spoilt etc.; Derailment accident just can't be avoided.
People are studying the railway locomotive problem of anti-" overstepping the limit " always for these years, and are in the technical field that prevents that locomotive from " overstepping the limit ", existing as Chinese patent 200420081589.4 " the wireless trip dog of rail locomotive ".This technology several years the implementation phase in exposed a defective, promptly " four open " signal source is from same collection point: " track switch light switch ".Because " track switch light switch " originally only was responsible for the track switch indicator lamp, the quality and the control precision of power supply all compare " coarse ".The acquisition of signal of the wireless trip dog of current track locomotive is parallel to " track switch light switch " and shares, and the interference of indicator light circuit and not matching of " track switch light switch " stroke action have been disturbed the particularity of the wireless trip dog of rail locomotive thus.So the signal source particularity of rail switch is the key of the wireless trip dog of rail locomotive.
Guarantee the accurately reliable of the wireless trip dog of rail locomotive; The particularity of acquisition of signal is depended in its source, and prior art can only be shared on " track switch light switch ".Because the signal output of existing tradition " track switch light switch " has only the signal source of pair of switches amount, except shared parallel connection does not have other ways.The result that signal is shared is particularity and the reliability that has hindered the wireless trip dog of rail locomotive.As guaranteeing the accurately reliable of the wireless trip dog of rail locomotive, must have another to collect synchronous, independently, stable, incorporate, adjustable signal source is given.This shows, the source that avoid locomotive " to overstep the limit ", the railroad switch point closure synchronous sensor of function admirable is crucial.
Because railway switch is the external parts that thoroughly are exposed to the light of day, the signal transducer of using at switch location must be at the burning sun high temperature that time keep out 70 ℃ (hot-metal ladle and carriage of iron and steel enterprise's inner tracks through out-of-date also can be up to more than 200 ℃) that is exposed to the sun.Want during severe winter tolerate subzero 25 ℃ low temperature, also have rumbling and the locomotive vibration crossed impacts the infringement of the infiltration of boundless heavy rain, darkness humidity, industrial dust aggressive fume etc.So exacting terms makes the components and parts of precise electronic class to use, and has suppressed railway signal external sensing parts advance.
In the prior art with railroad switch point closure synchronous sensor similar have 2, as Chinese patent: 00249022.6 1 kinds of contactless switch closure sensors and 00249024.2 1 kinds are near switching regulator switch closure sensor.These two technology all are single to signal output, can't satisfy the track switch sensing requirement of the wireless trip dog of rail locomotive, and all use the electronics package product of operating temperature tolerance difference, can't tackle practical needs at all.
Summary of the invention
Technical matters to be solved by this invention has provided a kind of railroad switch point closure synchronous sensor, can independently export two paths of signals synchronously, one the tunnel gives the track switch light switch, one the tunnel gives the wireless trip dog of rail locomotive, the independent glitch-free signal of two-way is precise and stable, has guaranteed the safety of switch track lane change.
