A switch 100 in accordance with an embodiment of the present disclosure for converting a rail vehicle from one lane to another is described below with reference to Figures 1-5. The switch 100 can be a straddle track turn for the conversion of the traverse rail vehicle. For example, the switch 100 can be a straddle single track ram for the conversion of the straddle monorail.

Ordinary trains support the left and right sides of the body through two rails. The straddle type refers to the bogie of the rail vehicle riding on the track, the straddle-type rail vehicle is supported by the rail located in the middle of the vehicle body, and the bogie covers the rail from both sides downward.

The first cart 31 is mated with a guide rail, and the first cart 31 is movable along the guide rail.

The first truss 11 and the second truss 12 are fixedly connected to the first trolley 31, for example, the first truss 11 and the second truss 12 are fixedly connected to the first trolley 31 by screw fasteners, that is, It is said that the first truss 11 and the second truss 12 are connected as a rigid unit, and the first girders 11 and the second girders 12 can be rotated together about the axis of rotation 43.

The driving unit 41 is configured to drive the first ballast beam 11 and the second ballast beam 12 to rotate about the rotation axis 43, to connect the first ballast beam 11 between the front end beam 15 and the first rear end beam 13, or to make the second ballast beam 12 is coupled between the front end beam 15 and the second rear end beam 14.

It can be understood that since the first ballast beam 11 and the second ballast beam 12 are fixedly connected to the same trolley as a rigid whole, the number of the trolleys and the connection between the ballasts of the ballast 100 can be reduced, and the number of components is small, the whole The switch 100 has an axis of rotation 43. Thus, when the driving unit 41 is in operation, there is no relative movement between the first ballast beam 11 and the second ballast beam 12, and the first ballast beam 11 and the second ballast beam 12 can rotate together around the rotation axis 43 to facilitate control of the turnout 100 rotation.辙 Precision.

The front end of the first truss 11 and the front end of the second girders 12 are selectively contiguous with the front end beam 15, and the rear end of the first sill beam 11 and the first end of the first sill beam 11 are joined to the front end beam 15 A rear end beam 13 is butted, and the rear end of the second ballast beam 12 abuts the second rear end beam 14 when the front end of the second ballast beam 12 abuts the front end beam 15.

As shown in FIGS. 1 and 4, the front end of the second ballast beam 12 abuts the front end beam 15, and the rear end of the second ballast beam 12 abuts the second rear end beam 14, so that the rail vehicle can travel from the front end beam 15 to the first The second rear end beam 14, i.e., the rail vehicle, enters from the front end beam 15 and passes through the second side truss 12 to enter the second rear end beam 14.

According to the embodiment of the present disclosure, the switch 100 has a small number of components, light weight, small start-stop impact, high overall stability and reliability, high positional accuracy during turning, low production difficulty, and cost saving.

As shown in FIG. 1 to FIG. 2, the switch 100 according to an embodiment of the present disclosure may further include: a second bottom plate 22, a second trolley 32, a third bottom plate 23, and a third trolley 33.

The second carriage 32 is rotatably mounted on the second bottom plate 22 about the rotation axis 43. For example, the second bottom plate 22 may be provided with a guide rail, the guide rail has a circular arc shape, and the center of the circular arc is at the rotation axis. At 43, the second cart 32 is mated with the guide rail and the second cart 32 is movable along the guide rail. Both the first girders 11 and the second girders 12 are fixedly coupled to the second trolley 32. For example, the first girders 11 and the second girders 12 are fixedly coupled to the second trolley 32 by threaded fasteners.

The third carriage 33 is rotatably mounted on the third bottom plate 23 about the rotation axis 43. For example, the third bottom plate 23 may be provided with a guide rail, the guide rail has a circular arc shape, and the center of the circular arc is at the rotation axis. At 43, the third carriage 33 cooperates with the guide rail, and the third carriage 33 is movable along the guide rail. Both the first truss 11 and the second truss 12 are fixedly coupled to the third trolley 33. For example, the first girders 11 and the second girders 12 are fixedly coupled to the third carriage 33 by threaded fasteners.

The first trolley 31, the second trolley 32, and the third trolley 33 may be spaced apart along the longitudinal direction of the switch 100 such that the first carriage 31 and the second ramp 12 are respectively received by the first carriage 31, The support of the second carriage 32 and the third carriage 33, the first truss 11 and the second truss 12 are more rigid.

The first carriage 31, the second carriage 32, and the third carriage 33 collectively connect the first truss 11 and the second truss 12 into a rigid unit, eliminating the need for the first girders 11 and the second girders 12. A variety of link members, and the number of trolleys can be reduced by half.

It can be understood that the axis of the hinge shaft between the hinge seat 42 and the first carriage 31 is the rotation axis 43. The rotation axis 43 is shorter than the rear end of the first ballast beam 11 and the rear end of the second ballast beam 12. That is, the distance from the first rear end beam 13 and the second rear end beam 14 is short, and when the driving unit 41 drives the first ballast beam 11 and the second ballast beam 12 to rotate, the front end of the first ballast beam 11 and the second ballast The front end of the beam 12 can be moved to a large extent, and the rear end of the first ballast beam 11 and the rear end of the second ballast beam 12 have a short moving path, which facilitates the docking of the first ballast beam 11 with the first back beam 13, and The second beam 12 is docked with the second rear beam 14.

As shown in FIG. 1 to FIG. 5, according to the switch 100 of the embodiment of the present disclosure, the driving unit 41 may be connected to the second trolley 32, for example, the driving unit 41 may have a push rod, and the push rod is hinged with the second trolley 32, and The axis of the push rod does not intersect the axis of rotation 43 to prevent dead spots. The telescopic movement of the push rod can be converted into the rotation of the first carriage 31. The drive unit 41 can include motor drive, hydraulic drive, air pump drive, and the like.

That is, the driving unit 41 can directly drive the second trolley 32 to rotate about the rotation axis 43, and the second trolley 32 can drive the first ballast beam 11, the second ballast beam 12, the first trolley 31, and the third trolley. 33 turns.

The switch 100 of the embodiment of the present disclosure directly drives the second trolley 32 through the driving unit 41, which is more convenient to install, adjust, and maintain, while avoiding the provision of the welded connecting member for connecting with the driving unit 41 on the ballast 100 beam. The local stress is concentrated, and the distance between the second cart 32 and the axis of rotation 43 is moderate, which can produce a larger force arm and a relatively stable power output.

Of course, the driving unit 41 is not limited to being connected to the second bogie 32, but may be connected to the first bogie 31, the third bogie 33, or to the first ballast beam 11 or the second ballast beam 12.
