Automatic train unhooking device

Abstract

The invention relates to the field of railway traffic auxiliary equipment, and provides an automatic train unhooking device which comprises a large-dip-angle clamping mechanism, an unhooking rotatingmechanism, a rotary lifting mechanism and a large arm pitching mechanism. The large-dip-angle clamping mechanism comprises a left clamp, a right clamp, a fixed pin shaft, a clamp connecting base, a clamp oil cylinder, a clamp frame, a clamp push-out oil cylinder and a push-out oil cylinder base. A cylinder body of the clamp push-out oil cylinder is arranged on the push-out oil cylinder base, and apiston rod of the clamp push-out oil cylinder is fixedly connected with the clamp frame. The fixed pin shaft is arranged on the clamp frame; a cylinder body of the clamp oil cylinder is arranged on the clamp frame, and a piston rod of the clamp oil cylinder is fixedly connected with the clamp connecting base. The left clamp and the right clamp are hinged to the clamp connecting base. The left clamp and the right clamp are hinged to the fixed pin shaft and extend out of the clamp frame. The device is high in automation degree, the working intensity of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of railway traffic auxiliary equipment, in particular to an automatic decoupling device for trains. Background technique [0002] It is necessary to separate the train carriages before unloading, transshipment or reorganization. This work currently requires manual operation of the train hook to separate the train carriages. Currently, the train dumping system is fully automatic. There is a big safety hazard in the operation of lifting the hook; at the same time, it is difficult to connect with the overturning system in the hook removal work with manual participation, which not only reduces the stability of the train unloading system, but also greatly reduces the unloading efficiency; [0003] Existing unhooking technology: 1.

[0002] The train carriages need to be separated before unloading, transshipment or reorganization. This work currently requires manual operation of the train hook to separate the train carriages. Currently, the train dumping system is fully automatic. There is a big safety hazard in the operation of lifting the hook; at the same time, it is difficult to connect with the overturning system in the unhooking work with manual participation, which not only reduces the stability of the train unloading system, but also greatly reduces the unloading efficiency;

[0003] Existing unhooking technology: 1. The existing unhooking equipment has a large volume and cannot be unhooked in the narrow space of the adjacent carriage; 3. The existing dehooking equipment requires the train to stop at a fixed position before dehooking, which cannot be matched with the current unloading system; Under long-term human operation, the hook lifting rod is partially bent and deformed, and the existing hook removal cannot grasp the hook lifting rod, and the hook removal cannot be completed; 5. During the stop process of the carriage, there is a stretching or compression jam of the coupler The existing hook removal equipment performs the hook removal operation on the hook lever, even if the hook lever is rotated and deformed, it cannot complete the operation of separating the carriage
