A vehicle-mounted lifting device for railway vehicles

Abstract

The invention discloses a vehicle-mounted lifting return device of a railway vehicle. The device comprises lifting return mechanisms mounted around a vehicle frame, a power source mounted on the frame, a power supply, a butt joint socket and a control box placed on a vehicle, wherein the control box is connected with the power supply, a relay and the butt joint socket through a cable (19); a switch or a button on the control box can singly or synchronously control actions of a transverse power machine and a vertical power machine; the lifting return mechanisms comprise moving mechanisms (4); the moving mechanisms (4) are connected with guide rails (5); and the transverse power machine (9) is mounted between the guide rails (5) through a mounting base I (8). The vehicle-mounted lifting return device of the railway vehicle is mounted on the railway vehicle frame without needing carrying, assembly and disassembly; and as rescue lifting return persons can take the control box to examine and determine the detained state around the frame to, the vehicle is guaranteed to locate in a horizontal state, and the operation is finished in the sight range of the rescue lifting return persons, the labor intensity is greatly reduced when the rescue lifting return safety is guaranteed.

Description

technical field [0001] The invention relates to a vehicle-mounted recovery device for a railway vehicle, in particular to a vehicle-mounted recovery device installed on a railway vehicle, and belongs to the technical field of railway rescue recovery equipment. Background technique [0002] A railway vehicle derailment accident is a serious accident that disrupts the order of railway transportation. After the accident, a safe and efficient recovery device is needed to carry out rescue and recovery work. There are various states of vehicle derailment, especially when the vehicle is tilted, which brings great difficulties and dangers to rescue and recovery, and it is easy to cause the vehicle to slip during recovery. The patent with the publication number CN 204488819 U discloses a hydraulic rerailer. This mechanism uses the lifting device to be placed above the rail, and the oil cylinder is lifted against the coupler, axle, frame, etc. of the derailed vehicle. The traversing ...

AI Technical Summary

Problems solved by technology

Rescue and recovery personnel are less safe when operating under the vehicle, and the whole process takes a long time

However, the patent document whose publication number is CN104773187 A does not consider that the vehicle is tilted after the derailment of the vehicle. During the recovery process, the vehicle cannot be adjusted to a horizontal state first, and there is a danger of slipping during the recovery process, and related operations need to be carried out on the vehicle, resulting in Rescue and recovery personnel cannot monitor the entire recovery process within their own line of sight, and there are blind spots. Coupled with the noisy environment on site, rescue and recovery personnel are prone to operating errors and cannot be aware of it, which will bring major safety hazards to the recovery , and the distance between the rescue and recovery personnel and the vehicle is too close to ensure the safety of the recovery and recovery personnel
