At present, rail electric locomotives are widely used in the auxiliary transportation system of coal mines in my country, and they are responsible for the important task of transporting production personnel and various equipment to and fro. In the entire transportation system, the reasonable operation and scheduling of electric locomotives will directly affect the transportation efficiency and transportation cost. The traction and transportation of electric locomotives used underground is generally monorail operation and single-machine one-way driving, which can travel back and forth in different roadways and tow mine cars. When reaching the destination, the electric locomotive needs to turn around and then drive in the reverse direction. This requires the construction of some vehicle dispatching yards for power supply locomotives turning around and reversing in the coal mine. The dispatching yards require a lot of space, high construction costs, and high efficiency. Low, increasing the mining cost of coal. If some special devices for locomotive turning and turning are installed in the vehicle dispatching yard, at both ends of the rail transportation line or near a certain work and production site, when in use, drive the electric locomotive to the turning and turning device at a slow speed and rotate with the device 180 °, then the U-turn of the electric locomotive can be completed. Then, the electric locomotive drives down the U-turn device, and goes to the rear of the mine car formation through a section of fork or wrong car lane, so that the reverse direction traction and transportation of the mine car can be realized.

Below in conjunction with the embodiment in the accompanying drawings, the utility model will be further described:

The rotary head-turning device of the present utility model is mainly composed of a supporting device, a driving device, a rotating mechanism, and a control system; the supporting device is composed of two linear tracks 9, a rotating platform 5, a supporting base 7, a bearing 8, and a circular track 3. It is the basis of the whole device, the supporting base 7 and the circular track 3 are set in the concrete foundation 1, fixed by the pressure plate 2, the rotating platform 5 is arranged on the supporting base 7, and two linear tracks 9 are arranged on the rotating platform 5; The device is composed of a motor reducer 13 and a sprocket transmission mechanism located on the side of the rotating platform 5, which provides rotational power for the U-turn device. The sprocket transmission mechanism is composed of a small sprocket 15, a transmission chain 16 and a large sprocket 17; the rotation mechanism It consists of seven supporting wheels 4 arranged under the rotating platform 5 and rotating along the circular track 3 and a driving wheel 14 driven by a sprocket transmission mechanism; the power is transmitted to the driving wheel 14 through the chain transmission pair, and the driving wheel 14 is connected to the circular The track 3 carries out rolling friction to generate a walking moment, supports and drives the locomotive on the rotating platform to rotate together with the seven supporting wheels 4, and completes the U-turn of the locomotive. The control system is composed of a sensor 10, a circuit, two control panels 11, an electromagnetic positioner 18, etc. The sensor 10 is arranged under the two linear tracks 9, and the two control panels 11 are respectively arranged on the front and rear sides of the two linear tracks 9. On the corresponding rotating stand 5, it is fixed by bolts 6. Electromagnetic locator 18 is located at the matching place of the draw-in slots of running rail 19 at the entrance and exit of two linear tracks 9, and there are four sensors 10 arranged under the two linear tracks 9, which are symmetrically arranged according to the wheelbase of traction locomotive 12; The basic parameters of the U-turn device are determined by the size and weight of different electric locomotives.
