Multifunctional hydraulic hoisting rescue equipment

Abstract

The invention relates to multifunctional hydraulic hoisting rescue equipment which structurally comprises a first single-stage oil cylinder, a second single-stage oil cylinder, an oil cylinder pickaxecap, a T-shaped hanging ring, an upper hanging rope and a hanging hook device and further comprises an oil cylinder base coupling assembly. The bottom of the first single-stage oil cylinder and the bottom of the second single-stage oil cylinder are hinged to the oil cylinder base coupling assembly, the tops of the two single-stage oil cylinders are fixedly connected through the oil cylinder pickaxe cap and then hinged to the T-shaped hanging ring, and the T-shaped hanging ring, the upper hanging rope and the hanging hook device are hinged in sequence. The suspension hook device special for hoisting is arranged below the upper hanging rope, and an stop iron is arranged on the suspension hook device and can bear huge hoisting force after being matched with a square hole in a coupler body; an oil return pipe is arranged in each single-stage oil cylinder, and a hydraulic lock is arranged at the bottom; meanwhile, the two potential safety hazards of rope breakage of existing rescue equipment and breakage of an external oil return pipe of the oil cylinder are avoided, and the multifunctional hydraulic hoisting rescue equipment has the advantages of being reasonable in structure, large in rerailing distance, easy, convenient and efficient to install, not limited by terrains and the like.

Description

technical field [0001] The invention relates to the field of railway rescue equipment, in particular to multifunctional hydraulic lifting rescue equipment. Background technique [0002] A railway traffic accident is a vicious accident that disrupts the normal order of railway transportation. The traditional recovery and rescue method is to install a recovery and rescue device (including hydraulic cylinders, traversing trolleys, etc.) Carry out lifting and traversing operations for retracking. The installation process of the existing straight-top and lateral-moving double-rail rescue device is complicated, and the equipment is easily affected by the terrain during the laying process, resulting in uneven laying or ground subsidence, which leads to the phenomenon of vehicle slipping during the lateral movement and the expansion of the accident; at the same time, the existing lifting The single traversing distance of the equipment is short, and the wheelset of the locomotive wi...
