摘要：

为解决因重载铁路隧道内空间限制而导致现有救援设备无法实施救援的问题,研究一种重载铁路隧道车载式救援设备的设计方案。重载铁路隧道车载式救援设备以凹底平车为载体,结合折叠式龙门吊的设计思路,利用凹底平车升降,龙门吊支腿、橫梁展开与折叠,将事故车体与货物同时吊起、平移到凹底平车上运出隧道,实现吊、装、运、卸一体化;该设备可以适应狭窄隧道空间救援作业,减少救援作业环节,节省人力、物力投入,提高救援效率,快速恢复线路开通,且避免强行拖出和卸空货物等方式造成的车辆损毁和经济损失。结果表明:车载式救援设备的设计提供一种新的重载铁路隧道救援装备方案,可实现隧道内颠覆性事故整体车辆运出,解决隧道内受空间限制无法实施救援的问题。

Abstract:

This paper discussed the design scheme of a vehicle mounted rescue equipment for heavy haul railway tunnels, which aimed to solve the problem that the existing rescue equipment could not implement rescue due to the space limitation in heavy haul railway tunnels. Vehicle mounted rescue equipment for heavy haul railway tunnels took the concave bottom flat vehicle as the carrier, and incorporated the design idea of folding gantry crane. By using the concave bottom flat vehicle to lift, unfold and fold the outriggers and beams of the gantry crane, the accident vehicle and goods were lifted and translated onto the concave bottom flat vehicle and transported out of the tunnel, realizing the integration of lifting, loading, transportation and unloading. The equipment could adapt to space rescue operation in narrow tunnels, reduce rescue operation links, save manpower and material resources, improve rescue efficiency, fast recovery line opening, and avoid vehicle damage and economic losses caused by forced dragging and unloading of goods. The design of vehicle mounted rescue equipment provides a new scheme for heavy haul railway tunnel rescue equipment, and realizes the overall transportation of vehicles for subversive accidents in the tunnel.

Key words: tunnel, vehicle mounted, rescue equipment, accident vehicle, gantry crane, outrigger
