Track wheel, wheel carts, rotating turntable, roller wheel 
 Tub tub wheel machine is mine carts in the circulatory system to change the direction of the equipment with other equipment supporting the use of mechanized transport to facilitate the realization of the wellhead. To change the present tub mine the direction of transport, except with the turnout, but you have to use turn turn, this large area. The rotary machine using a smooth and reliable low-speed dial to make changes to a wide range of automated carts, the radius of curvature can be very small (only 3 m diameter circular machine). Features: small footprint, high efficiency, stable and reliable carts to change, adapt to the restricted space on the ground in parking lots and the direction of shaft bottom to change the tub; can play a small tunnel, save money, accelerate the construction pace. 
 The utility model involves mining equipment, specifically the track as a rotating turntable, hydraulic support the mine to solve the existing U-turn shift caused by the human, material and waste a great issues, including the turntable on the turntable and the lower, fixed on the turntable below the center hollow columns, set parallel to the surface on the track; under the turntable at the top center of the circle with center wheel, hollow column set in the center wheel, on the surface of the week under the turntable ring there are fabrics Vice wheel; under the turntable on the turntable and are located on the relative position a positioning hole. The utility model structure is simple, low cost processing of materials; production process is simple, easy to install; turntable carrying capacity of the strong, simple structure, can be reused many times, less maintenance work; save process, saving labor, to maintain the original roadway retaining the integrity of the air reduce the top area of ??the roadway, extends the life of Lane track mining area; In short, better in actual use, has some promotional value and use value, can be widely used in various mines. 
 One kind of track wheel can be rotated, which is characterized by including on the turntable (1) and under the turntable (2), on the turntable (1) below the hollow center of the fixed column (3), set parallel to the surface on the track (4); under the turntable ( 2) at the top center of the circle with center wheel (5), hollow column (3) sets of wheels in the center (5) upper and lower turntable (2) weeks on the surface of the ring there are fabrics Vice wheel (6); on the turntable (1) and under the turntable (2) the relative position of holes, respectively, with (7).
