The rail control part can adopt a self-adaptive control structure and also can adopt a mechanical clamping and positioning structure, compared with the prior art, the technical scheme realizes the elastic bending of the rail through the swinging of the beam, and controls the bending parameters of the rail through the rail control part, thereby simplifying the turnout structure and reducing the manufacturing cost.

The fixing piece used for connecting the steel rail and the track beam in the embodiment can be a steel rail fastener, and can also be other structures capable of realizing the connection of the steel rail and the track beam.

In this embodiment, the rail control unit has a self-adaptive control structure, and the following concrete structure:

in this embodiment, an inserting portion is arranged at one end of the movable beam 2, the inserting portion is inserted into the fixed beam 1, and the inserting portion is hinged to the fixed beam 1.

In order to connect the movable beam 2 with the fixed beam 1 and enable the movable beam 2 to swing in a horizontal plane, the movable beam 2 is hinged with the fixed beam 1, and in order to realize a self-adaptive control structure, a splicing structure is arranged at the hinged end of the movable beam 2 and the fixed beam 1, wherein the splicing structure refers to that one end of the movable beam 2 is inserted into the fixed beam 1, or the track installation surfaces of the movable beam 2 and the fixed beam 1 respectively extend out of one section, and the extension section of the movable beam 2 is overlapped with the extension section of the fixed beam 1.

In order to realize the control of the elastic bending of the movable rail 3, after the movable rail 3 is elastically bent, the rail gauge is ensured to be within a specified range, the technical scheme is that a plurality of second movable grooves 21 are arranged on the movable beam 1, a plurality of first movable grooves 11 are arranged on the fixed beam 1, as the inserting parts of the movable beam 2 and the fixed beam 1 are overlapped, the positions of the first movable grooves 11 and the positions of the second movable grooves 21 are in one-to-one correspondence, the lengths, the shapes and the angles of the first movable grooves 11 and the second movable grooves 21 are obtained by calculation, and the first movable grooves 11 and the second movable grooves 21 which correspond to each other after calculation are in a crossed shape.

The calculation of the length, shape and angle of the first movable groove 11 or the second movable groove 21 is essentially to calculate the moving track of the movable rail 3 relative to the fixed beam 1 or the movable beam 2 during the bending process, for example, to calculate the moving track of the movable rail 3 relative to the fixed beam 1 during the bending process, i.e. to calculate the first movable groove 11:

because the movable rail 3 is composed of two left and right single rails in parallel, and the bending motions of the left and right single rails are consistent in the elastic bending process of the movable rail 3, the following calculation takes the right rail as an example, a plane rectangular coordinate system O1 is established, one end of the right rail is set as the top end, the other end is the movable end, the right rail can be regarded as a cantilever beam, because the movable beam 2 swings left and right in the horizontal plane, a horizontal and right moment M is supposed to be applied to the movable end of the right rail, the moment M parallel to the X1 axis and along the positive direction of the X1 axis is supposed to be applied in the plane rectangular coordinate system, when the moment M is not applied to the movable end of the right rail, the right rail is in a straight state, the right rail is parallel to the Y1 axis, when the movable end of the right rail receives the action of the moment M, the right rail is in a bending state, the movable end of the right rail can be known according to practical application, the bending angle of the steel rail is small, so that the offset of the movable end of the right rail only considers the offset along the X1 axis, ignoring the offset of the right rail end along the Y1 axis,

assuming that the offset of the moving end of the right rail is d, the rectangular plane coordinate system O is adopted₁Get A₁、B₁、C₁Three points, A₁、B₁、C₁The coordinates of the points are expressed as

When the right rail is elastically bent under the action of the moment M, a plane rectangular coordinate system O is established₂After bending, the connecting line of the movable end and the fixed end of the right rail rotates alpha degrees relative to the straight right rail, and the rotation center is the fixed end of the right rail, namely a plane rectangular coordinate system O₂Rectangular coordinate system O relative to plane with origin as center of circle₁Rotated by an angle of alpha DEGThen in the rectangular plane coordinate system O₂Middle, corresponding A on the right rail₂、B₂、C₂The coordinates of the points are expressed as

Since the offset d of the right rail moving end is ranged, according to A₂、B₂、C₂The coordinates of the points, in combination with the offset d, can calculate the moving track of point A, B, C on the right rail, and the corresponding first movable slot 11 is based on the calculated moving track. The second active slot 21 is calculated in the same manner as above.

The rail control part is inserted into the intersection of the first movable groove 11 and the second movable groove 21, and when the movable beam 2 swings relative to the fixed beam 2, the rail control part controlled by the first movable groove 11 and the second movable groove 21 moves along the track.

According to the first movable groove 11 and the second movable groove 21 obtained by the calculation, since the first movable groove 11 and the second movable groove 21 are crossed, a cross point exists between the first movable groove 11 and the second movable groove 21, the cross point is a preset track of the bending of the movable rail 3, the rail control part is fixed at the cross point, and the bending of the movable rail 3 is controlled by the rail control part. The rail control part can be a pin shaft, a sliding block which can slide in the first movable groove 11 and the second movable groove 21 or other structures which can slide in the first movable groove 11 and the second movable groove 21, the rail control part is the pin shaft 5 in the embodiment, after the movable beam 2 swings in place, the movable beam 2 is fixed, the first movable groove 11 and the second movable groove 21 which are crossed limit the free movement of the pin shaft 5 in the horizontal plane, the elastic bending of the movable rails into a preset shape is also ensured, and the rail distance of the two movable rails is always in a set range.

In this embodiment, the rail control part includes a pin 5, and one end of the pin 5 is fixed to the fixing member.

In this embodiment, the driving fixing device includes a guide portion, a sliding portion, and a driving portion for driving the sliding portion to slide along the guide portion, and the free end of the movable beam 2 is fixed to the sliding portion.

In order to drive the free end of the movable beam 2 to swing left and right in the horizontal plane, the technical scheme is provided with a driving part for driving the free end of the movable beam 2, and a supporting frame for mounting a driving part is also arranged, the driving part can be an air cylinder, a hydraulic cylinder, a motor or other structures capable of pushing the free end of the movable beam 2 to move, the guiding part can be a chute or a steel rail, the sliding part can be a movable structure with a pulley, the sliding part is fixed with the free end of the movable beam 2, and the pulley rolls along the chute or the steel rail.

The swing mechanism further comprises limiting blocks arranged at two ends of the guide part, and the limiting blocks are used for limiting the swing angle of the free end of the movable beam 2.

Because the elastic bending of activity rail is also limited, in order to guarantee that the elastic bending of activity rail is at reasonable within range, 2 swings of activity roof beam when avoiding the drive division trouble and surpass the settlement scope, lead to the activity rail to take place irreversible plastic bending, this technical scheme sets up the stopper at the both ends of guide part, guarantees that the elastic bending of activity rail is at reasonable within range.

In this embodiment, the guiding portion is configured as an arc-shaped groove, and the arc-shaped groove takes a hinge point of the movable beam 2 and the fixed beam 1 as a circle center.
