Problems solved by technology

The herringbone type rerailer is used for hoisting the hook or axle of the vehicle. It is safer for the operator to operate outside the vehicle, and it is convenient and quick when there is power; It is unsafe to work under the ground, because it can only lift and reset the axle of the vehicle, with a single starting and returning point and poor adaptability
There are two types of ballast beds in existing high-speed railways. One is the ballastless track bed used in the main line and the section. The bottom surface of the rail is 20mm lower than the sleeper surface, and the difference between the two is 90mm, which makes it impossible to install and use the traditional herringbone rerailer. -120mm, sleeper width 460m, length 2500mm, laying a ballastless line, the existing herringbone rerailer can not be installed, especially bridges and tunnels occupy a considerable proportion of the total length of the line, which brings a lot of trouble to railway rescue difficulty

Embodiment 1

[0026] Such as figure 1 As shown, a lifting rescue method, the rerailing device used is as follows Figure 2-5 As shown, it includes the lifting oil cylinder 1 arranged on both sides of the derailed train, the upper part of the lifting oil cylinder 1 is equipped with an oil cylinder jacking, the middle position of the bottom of the lifting oil cylinder 1 is provided with a semicircular groove, the upper surface of the jacking is smooth, and the two sides of the jacking are flat. One hanging ear 5 is arranged on each side. The base 2 includes a bottom steel plate. A baffle plate with a semicircular groove 7 in the middle is welded on both sides of the steel plate. The size of the groove 7 is consistent with the size of the bottom groove of the lifting cylinder 1. The first lifting lug is installed on the baffle plate of the base through the round hole 6, the connecting rope 3 is connected to the two bases 2 through the lifting lug, the two bases 2 are connected with the connec...

Embodiment 2

[0030] Such as Figure 6 As shown, a lift-type rescue method, the rerailing device includes a lift cylinder 1, a base 2, a jacking support, a hydraulic pump station, a traverse beam 10, a traverse trolley 11, a rotary table 12 and pads. The specific implementation method is: under the off-line wheel bogie of the derailed train, a base 2 is placed between the rail and the roadbed, a lifting oil cylinder 1 is placed in the base, a jacking bracket is installed on the lifting oil cylinder, and the jacking is fixed on the car body frame For the parking space, use oil pipes to connect the hydraulic pump station with the lifting cylinder 1 and the traversing trolley 11 respectively, turn on the hydraulic pump station, lift the lifting cylinder 1 to lift the car body, place the traversing beam 10 under the bogie in turn, Install the traversing trolley 11 on the moving beam 10, place the rotary platform 12 on the traversing trolley 11, place an adjusting block with a suitable thickness...

Abstract

The invention discloses a lifting type rescue method, and belongs to the technical field of railway train rescue. The method comprises the following steps: a connecting rope is placed between a steelrail under an off-line wheel bogie and a roadbed, bases are placed on the two sides of a derailed train, the two ends of the connecting rope are connected with the bases, lifting oil cylinders are installed on the bases, and wheel stoppers are installed on the outer side faces of the steel rail on the outer side in the rerailing direction; a jacking support is installed at the top end of the lifting oil cylinder and fixed to a vehicle body frame parking space; and the lifting oil cylinders and a hydraulic pump station are connected through oil pipes; the two lifting oil cylinders support and lift up the vehicle body and sideslip towards the rerailing direction to get close to the steel rail; and when the rim of the wheel is higher than the rail surface, the wheel resets, and rerailing is completed. According to the train rerailing method, all lifting recovery machines and tools are installed outside the train body, and the method is suitable for various rails, convenient to operate andsafe to use.

Description

technical field [0001] The invention relates to a lifting rescue method, which belongs to the technical field of railway train rescue. Background technique [0002] Railway transportation is the most important and economical mode of transportation in the world today, and has an irreplaceable advantage in the world freight and passenger transportation market. With the opening of the Wuhan-Guangzhou high-speed railway, it symbolizes that my country's railway has entered a high-speed era. The train derailment accident is a vicious accident that disrupts the normal order of rail transportation. Especially the structure of the EMU is complex, there are many models, and the price is expensive. The existing rescue equipment cannot effectively play a role. Therefore, the rescue and recovery operation of the high-speed rail EMU accident is facing new issues and challenges. [0003] At present, the rerailers commonly used in China are herringbone rerailers and traverse rerailers. The...
