The tail of the retractable belt conveyor is suitable for the convergence of the retractable belt conveyor and the retractable belt conveyor in the transportation lane of the coal face and has the advantages that the scraper transfer machine and the tail end of the self- Retractable belt conveyor at the tail of the conveyor belt deflection, scraper transfer machine head height adjustment and other functions to ensure that the cis-slot transport reprint unobstructed to meet the high-yielding high-efficiency face, advanced support requirements are fast Today’s coal long wall face to achieve high yield and efficiency of the preferred equipment.

In the process of self-moving tail sliding forward, due to uneven resistance, often appear tail shift tail transfer, resulting in tape deviation, and then the phenomenon of coal leakage. Therefore, the shift tail should be a function of lateral shift, in order to improve the flexibility and reliability of the shift, the use of hydraulic cylinder side shift type. Since the end of the tail rotor to sled orbit, by adjusting the cylinder side of the hydraulic cylinder and the coordination of telescopic, to move the tail of the move to achieve lateral movement to achieve the purpose of adjusting. In order to reduce the bore diameter, two side shift hydraulic cylinders are respectively installed between the skid and the skid shoe at the tail end of the tail end of the transfer machine. According to the arrangement of the equipment along the trough, the minimum width of the tail end and the required lateral displacement To determine the side shift cylinder stroke and lateral displacement of respectively 200mm and 245kN 1.3 Sliding Car Structure Design Sliding trolley is one of the important working parts of the self-tailing tail, its role is to support the scraper transfer machine head And its bridging section, so that it can move back and forth on the main rack track, while accepting the coal from the loader, but also the fulcrum from the end of the shift tail, therefore, need to optimize the structure and the rational use of materials to improve the car The strength of the key parts and the overall stiffness. It is mainly composed of frame, front wheel, hinged frame, rewinding drum and redirecting drum and other parts, the structure as shown. Retrofit drum mounted on the car, reducing the length of the machine, which can shorten the length of the supporting scraper plate rack section, to improve the self-moving tail of the force situation. In order to improve the force of sliding trolley, the four wheels of the trolley need to keep good contact with the rail while the main rack rail deflects, so the connection between the rear axle and the frame is designed as a pivot hinge.
