[0002] Roadway rail transport is a key mode of transportation within mines, boasting advantages such as high transport capacity, high mobility, and adaptability. It utilizes rails and mine cars to transport personnel and materials within roadways. Roadway rail transport is applicable not only to horizontal roadways but also to inclined roadways, and can uniformly address the transportation of different types of coal and auxiliary materials. At the same time, roadway rail transport requires strict safety management and maintenance and inspection systems to ensure safe and stable transportation. This mode of transportation is widely used in industries such as metal mining and coal mining.

[0003] In tunnel rail transportation, turnouts are indispensable facilities. In some complex routes, turnouts need to be used in a limited area to achieve multi-directional traffic. However, the tunnel is narrow and it is impossible to set switches next to the tracks to switch the tracks. Therefore, a positioning shaft-type swingable cross rail is proposed.

A positioning latch is movably mounted under the electromagnet, a return spring is sleeved on the positioning latch, a spring seat is fixedly mounted on the positioning latch, and an armature block is fixedly mounted on the upper end of the positioning latch. When the electromagnet is energized, it will adsorb the armature block to disengage the positioning latch from the positioning slot.

[0006] Preferably, the servo motor is provided with a motor frame, and the servo motor is fixed to one side of the helical gear plate through the motor frame, and the driving motor can drive the helical gear to rotate.

[0007] Preferably, a bearing is provided in the driving gear, and the driving gear is movably mounted on the driving column through the bearing. The helical gear can drive the helical gear plate to rotate, and the helical gear plate can drive the driving gear to rotate when it rotates.

[0008] Preferably, the driving gear is movably mounted on one side of the arc-shaped rack through a driving column, and the driving gear is meshed with the arc-shaped rack. The helical gear is movably mounted above the helical gear plate through a servo motor, and the helical gear is meshed with the helical gear plate. After the driving gear rotates, it will roll along the arc-shaped rack.

[0009] Preferably, a limiting slot is provided in the positioning slot, and the positioning pin is embedded in the positioning slot through the limiting slot. One end of the return spring is fixed on the spring seat, and the other end of the return spring is connected to the inner wall of the movable slot.

The drive gear rolls along the arc-shaped rack, thereby driving the swing track at the top of the drive column to swing about the positioning shaft. Adjusting the swing track's position allows it to connect with different tracks at a switch in a narrow lane, enabling multi-directional passage.

[0014] 2. In this application, the electromagnet is connected in series with the servo motor. After the position of the moving track is adjusted, the servo motor is disconnected from the power supply, causing the electromagnet to close and release the armature block. Once the armature block is released, the return spring pushes the positioning pin downward, causing it to engage with the limit slot, preventing the swing track from swinging freely and improving the stability of the swing track connection.
