Description

Railway trouble switching device

The utility model relates to other auxiliary equipment that are used for railway, relates in particular to railway trouble switching device.

Existing track switch of having realized the railway motorized is to rely on the direct current drive goat to drag track switch.It is big to exist maintenance load, and power-supply system requires high, and pulling force is little, does not possess shortcomings such as the property of squeezing.Though the electric point machine of import can squeeze, but it is bulky, Heavy Weight, operating current big (＞10A), traverse big (210mm), drive the cumbersome complexity of action machinery of its home loop controller, functional reliability and poor stability, cost an arm and a leg, and every index does not meet the 5th joint common requirement that relevant goat proposed in Ministry of Railways's " signal maintenance rule ".

The purpose of this utility model provides a kind of railway simple and compact for structure trouble switching device.

The utility model is taked following measures in order to achieve the above object: it has first coupling bar, the first coupling bar two ends link to each other with two points of switch respectively by connecting iron, be welded with two sleeves on the Different Plane of first coupling bar middle part, link to each other with two adjustable switch operating rods respectively, adjustable switch operating rod links to each other with the slider that can squeeze the electronic goat of formula single phase ac again, with about closely connected detector is housed on two the mobile point of switch corresponding two basic rails respectively.

The utility model has the advantages that: simple and compact for structure, volume is little, in light weight, low cost of manufacture, and is safe and reliable to operation.Drag reducing gear with the high slip motor of a kind of single phase ac, realize the turn-out track of track switch, the electronic switching device of squeezed formula of locking.And every index meets the 5th joint common requirement that relevant goat proposed in Ministry of Railways's " signal maintenance rule ".

Railway trouble switching device has first coupling bar (3), the first coupling bar two ends link to each other with two points of switch respectively by connecting iron (2), be welded with two sleeves (4) on the Different Plane of first coupling bar middle part, link to each other with two adjustable switch operating rods (5) respectively, adjustable switch operating rod links to each other with the slider (11) that can squeeze the electronic goat of formula single phase ac (6) again, with about closely connected detector (1) is housed on two the mobile point of switch corresponding two basic rails respectively.Can whether reliable be used for detecting tongue locking closely connected, thereby obtain the signal that allow train pass through, and reaches the purpose of safe turn-out track.First coupling bar is a slidingtype, empty moving distance＞25mm.

Can squeeze the electronic goat of formula single phase ac, has the high slip motor of monophase ac capacitance-run (7), and successively with reducer (8), friction coupling device (9), conversion gear (10), slider (11) links to each other, and the tooth bar of slider (13) joins with the push rod (17) of loop control unit (12), is provided with manual handle mechanism and spring supporting bar (16) on conversion gear.Motor only is operated in starting state, and the 1.2-1.3 that starting current has only rated current doubly, is provided with three groups of taps on the winding of motor, pressure drop requirement when satisfying goat and signal box different distance, three groups of taps are respectively applied for pressure drop at I:0-15V, II:15V-45V, III:45V-60V.This motor mounting is vertical installation on deceleration box.

Slider has the tooth bar (13) that is loaded on slider base centre, is positioned at the actuating strut (14) of tooth bar left and right sides.Tooth bar is connected by two triangle link stoppers (15) with left and right sides actuating strut.Establish two steps on the back of tooth of tooth bar, lead angle α=30 of step °, the triangle block has relative rotation with actuating strut, and moving of tooth bar driven by conversion gear.Tooth bar moves between the chute of its base and guide strip, and guide strip is fixing on the cover board, and cover plate is fixed in the casing.The stroke of tooth bar is limited by base.On the cover board respectively two locking baffle plates are fixed in the left and right sides of guide strip.When actuating strut moves to left when putting in place, its actuating strut by being installed on the triangle block on the actuating strut bumping post and add and help spring supporting bar, it is locked in the arc surface of left locking baffle plate; When actuating strut moves to right when putting in place, with its be locked in right locking baffle plate circular arc and in.Moving of tooth bar depended in moving of actuating strut fully.On the back of tooth of tooth bar, process two steps, lead angle α=30 of step °, when the peak on the back of tooth contacts with the push rod that drives loop control unit respectively with minimum point, its push rod has just moved 20mm (if be zero point with the tooth bar back side, promptly to peak and the mobile respectively 10mm of minimum point) thus driven loop control unit work, the controller contact be in out or close state, guaranteed actuating strut about put in place.Goat disposes manual handle mechanism to be made up of float type clutch and cam, when having a power failure manual handle is pulled 180 °, finishes the conversion of track switch.

This device has the property of squeezing.When external force acts between tongue and the stock rail (tongue is when tearing state).External force (＞110kg) reaching actuating strut by first coupling bar and adjustable switch operating rod, non-locking bar will produce displacement under the effect of external force at this moment, when displacement reaches 25mm, the locking bar release has guaranteed that goat and tongue are not damaged, and has guaranteed the safety of driving.What is called has the goat of squeezing property.Exactly when being used as a trailing-point switch; that is to say when two circuits to the direction of single line near the time; the vehicle of the circuit that does not without damage conform to by the direction of adjusting from goat from the goat, goat is by the displacement of warp-wise thrust then, thereby plays the effect of protection tongue.When a goat by from single line and the vehicle institute of driving towards one of one group of different circuit near the time, we just say that this goat is used as facing point.
