1. , turnout machinery in the aerial three-dimensional walking steel network is by center, 1 " V " shape turnout rail, 3 pairs of crooked rail of double rocking lever, 3 frame billets and 3 groups of electromagnetism drag (electronic) machinery etc. respectively correspondence be combined into 1,2, common formation such as 3 double rocking lever machineries, it is characterized in that:

  • this turnout machinery is mounted in the track and hangs and draw the girder steel frame to hang to draw on the two light rails track that fixes, the track of its use is hung and drawn the girder steel frame is according to using needs to be out of shape some for machinery convenient purpose made in turnout is installed, as removed the main beam two ends to the limit, upper edge, crossbeam length also needs according to frame billet shape and has shortened some, the track hang the distance of drawing between the girder steel frame also littler etc.;

    It is characterized in that;

    3 frame billets according to its separately the actual needs that constitutes of double rocking lever machinery be made into various required forms, its outside does not exceed the track and hangs and draw girder steel frame main beam two ends generally speaking, reserves the distance that essential running block framework case running body passes through between heart billet limit, bend road and heart billet limit, road, straight line track;

    And the level height of billet should guarantee that the crooked rail horizontal hunting of double rocking lever can not be hindered by the billet below the straight rail etc. when the straight rail contact surface docks;

    The connecting link pin of 3 pairs of crooked rail of double rocking lever and its billet can be emerging on the rail level, also can not reveal, and it does not show the same, definite according to actual needs in force with the bearing pin connection of connecting rod;

    It is characterized in that;

    double rocking lever machinery is to be made of frame billet, the crooked rail of the 1 pair of double rocking lever and connecting rod etc., and 3 double rocking lever machineries are made of respectively similarly its corresponding component of machine respectively;

    It is characterized in that;

    the propelling thrust that electromagnetism drags on (electronic) mechanical mechanical pull bar acts on the connecting rod, connecting rod promotes the crooked rail of 1 pair of double rocking lever and make horizontal hunting on its billet, and can only rest on to dock and become on the single-piece position with straight line track rail (and and center, " V " shape turnout rail), or can only rest on the position of leaving straight line track rail (and and center, " V " shape turnout rail) segment distance, and be locked on this stop place by powerful electromagnetism driving machinery power;

    Also can adopt simultaneously and add various mechanical systems such as mechanical pin is installed in addition the banjo connection place of crooked rail and straight rail is carried out mechanical caging again on this stop place;

    Equally, other 2 double rocking lever machineries also are that the mechanical pull bar masterpiece at the electromagnetism driving machinery is used on its connecting rod and makes the crooked rail of these 2 pairs of double rocking levers also make horizontal hunting on its billet, and can only rest on the track bond of straight line track and become on the single-piece position, or can only rest on the position of leaving straight line track rail one segment distance, and all be locked on this stop place with electric means or mechanical system;

    After control center sent control command, this lock-out state just can be disengaged, and after this turnout machinery just can be worked to change opening and inaccessible situation of turnout again;

    It is characterized in that;

    the miles of relative movement of the crooked rail of double rocking lever that is positioned at the straight line track is very little, only for conveniently passing through along the limit in the movable pulley, and the miles of relative movement of the crooked rail of 2 pairs of double rocking levers in other 2 bends is very big, so that limit, movable pulley outer and running block frame casing etc. are convenient current;

    It is characterized in that;

    center, " V " shape turnout rail rail level partly has 2 opennings of the cut one-tenth of one little section very short rail level of 2 places, and its prismatic center rail level is only connected by its underpart girder steel and other parts rail level etc. and is retained as the whole rail of " V " shape;

    It is characterized in that;

    the rate of curving of 3 pairs of crooked rail of double rocking lever all is to determine according to actual needs, (contact surface of straight line track rail can be semisphere for itself and straight line track rail contact surface, also can be made into two contact sides is a little inclined-plane or a trapezoidal faces etc., needs to determine according to actual the use) be the contact of little inclined-plane;

    It is characterized in that;

    turnout machinery can only be operated in two mode of operations shown in [1] and [2], and the transient state in the middle of it is to finish moment;

    Its job procedure has been that storehouse theorem defined is by 1,2,3 order or is undertaken by 3,2,1 order conversely for its mechanical and electric structure self-lock mechanism, be that this turnout machinery will show that state becomes [2] and shows state by [1], ability 2 machine works of showing after 1 machine work of showing are only 3 machine works of showing thereafter earlier;

    Turnout machinery will show that state becomes [1] and shows state by [2] conversely, then earlier could 2 machine works of showing after 3 machine works of showing, be only 1 machine work of showing thereafter, and wherein do not allow the illegal work of random order to cause damage equipment, to guarantee traffic safety.
