Track turntable use

The track turntable is a device that changes the direction of the mine car in the mine car circulation system. It is used in conjunction with other equipment to facilitate mechanized transportation at the wellhead.

Orbital turntable structure

The track turntable includes an upper turntable and a lower turntable. A hollow column is fixed below the upper turntable, and a parallel track is arranged on the upper surface; a wheel is arranged at the center of the circle above the lower turntable, and the hollow column is sleeved on the wheel, and auxiliary wheels are evenly distributed around the upper surface of the lower turntable; positioning holes are arranged at relative positions on the upper turntable and the lower turntable.

Track turntable features

The rail turntable uses a stable and reliable low-speed turntable to automatically change the direction of the mine car over a large range, and the curvature radius can be very small. Compared with turnouts and curve turns, the rail turntable occupies less space, has high efficiency, and the mine car changes direction steadily and reliably. It is suitable for changing the direction of the mine car in ground yards and pit yards with limited space.

The track turntable has a simple structure and low processing material cost; the manufacturing process is simple and the installation is convenient; the turntable has a strong bearing capacity, a simple structure, can be reused many times, and the maintenance workload is small. It saves procedures, labor and effort, maintains the integrity of the original tunnel support, reduces the empty top area of ​​the tunnel, and extends the service life of the track tunnel in the mining area.
