Description

Technical Field

[0001] The invention relates to the field of railway rescue equipment, in particular to multifunctional hydraulic lifting and rescue equipment. Background Art

[0002] Railway traffic accidents are vicious accidents that disrupt the normal order of railway transportation. The traditional method of recovery and rescue is to set up a recovery and rescue device (including hydraulic cylinders, lateral movement trolleys, etc.) under the middle beam or hook of the locomotive or vehicle to lift and lateral move the derailed locomotive and vehicle to rerail. The existing straight-top lateral movement rerailing rescue device has a complicated installation process. During the equipment laying process, it is easily affected by the terrain, resulting in uneven laying or ground sinking, which leads to the phenomenon of slipping during the lateral movement, causing the accident to expand; at the same time, the existing recovery equipment has a short single lateral movement distance, and the wheelset of the locomotive and vehicle will sink deeply between the two sleepers after the derailment, which will cause the recovery point to be too low and the equipment cannot be laid, affecting the rescue. At the same time, the existing recovery hydraulic rescue equipment is not equipped with a hydraulic lock and the return oil pipe leaks. Outdoor operations are very likely to cause the return oil pipe to bump or break, posing a huge safety hazard. At present, the lower part of the Harmony electric locomotives operating in China is equipped with a traction rod, which cannot be used for top recovery and rescue. The use of cranes for rescue must remove the power grid, and the operation is large and cumbersome. Therefore, there is an urgent need to provide a multifunctional hydraulic rescue equipment that is suitable for a variety of complex working conditions, is not restricted by terrain when laid, and is safe and reliable. At the same time, when a railway locomotive or large track maintenance machinery is derailed in a tunnel due to some factors and other rescue equipment cannot be implemented or the implementation process is cumbersome and the workload is large, this equipment can be used to perform safe, reliable and fast rescue operations.
