Technical Field

The invention relates to a lifting type rescue method, and belongs to the technical field of railway train rescue.

Background

Railway transportation is the most important and economic transportation mode in the world at present, has no alternative advantages in the world freight transportation and passenger transportation markets, and indicates that the railways of China enter a high-speed era along with the opening of the Wuguang high-speed railways. Train derailment accidents are serious accidents which destroy the normal order of rail transportation, and particularly, motor train units are complex in structure, large in number and high in price, and existing rescue equipment cannot effectively play a role, so that the accident rescue and recovery operation of the high-speed rail motor train units faces new problems and challenges.

At present, the rerailers commonly used in China are herringbone rerailers and cross sliding rerailers. The herringbone rerailer is used for lifting a big hook or an axle of a vehicle, and an operator can operate outside the vehicle body, so that the operation is safe, and the operation is convenient and quick in a power situation; when the cross sliding type rerailer is placed, an operator needs to drill into the bottom of the vehicle to work, and the rerailer is unsafe, only can be used for rerailing the axle of the vehicle, has a single rerailing point and is poor in adaptability. The existing high-speed railway has two track beds, one is a ballastless track bed used in a main track and an interval, and is characterized in that the height between the top surface of a steel rail and the whole track bed is 250mm, the bottom surface of the steel rail is 70mm higher than the surface of the whole track bed, while the bottom surface of the steel rail of the traditional ballasted track bed is 20mm lower than a sleeper surface, and the difference between the two is 90mm, so that the traditional herringbone rerailer can not be installed and used, and the other is a plate type sleeper track bed used on a line in a station yard, wherein the distance between sleepers is 120mm, the width of the sleeper is 460m, and the length of the sleeper is 2500mm, and a ballastless line is laid.

Therefore, the research on rescue technical equipment and rescue methods of the high-speed railway motor train unit is imperative.

Disclosure of Invention

Aiming at the problems, the lifting type rescue method is suitable for various tracks, and is convenient to operate and safe to use. The technical scheme adopted by the invention is as follows:

a lifting type rescue method is characterized in that: the train derailment rescue method comprises the following steps:

a, placing a connecting rope between a steel rail and a roadbed below a derailment wheel bogie, placing bases on two sides of a derailment train, connecting two ends of the connecting rope with the bases, installing a lifting oil cylinder on the bases, and installing a wheel stopper on the outer side surface of the steel rail on the outer side in the direction of rerailing;

b, mounting a jacking on the top end of the lifting oil cylinder, fixing the jacking on a parking space of the vehicle body frame, and connecting the lifting oil cylinder with a hydraulic pump station by using an oil pipe;

c, two lifting oil cylinders lift the lifting vehicle body and sideslip towards the direction of the rerailing to be close to the steel rail;

and D, when the wheel rim of the wheel reaches the rail surface, the wheel slides on the rail, the wheel stopper blocks the wheel from sliding out of the rail, the lifting oil cylinder is descended, and the rail replacement is finished.

The technical scheme of the invention is further improved as follows: the base comprises a bottom steel plate, baffle plates with semicircular grooves in the middle are welded on two sides of the steel plate, round holes are formed in the front ends of the baffle plates, the two lifting lugs are installed on the baffle plates of the base through the round holes, and the connecting ropes are connected with the two bases through the lifting lugs.

The technical scheme of the invention is further improved as follows: the middle position of the bottom of the lifting oil cylinder is provided with a semicircular groove, the size of the groove is consistent with that of the groove of the base, and the lifting oil cylinder and the base are movably connected together through cylinders which are connected in the groove of the base and the groove of the bottom of the lifting oil cylinder in a penetrating manner.

The technical scheme of the invention is further improved as follows: the upper surface of the jacking support is flat and smooth, and two sides of the jacking support are respectively provided with a suspension loop which is used for being connected with a train bogie through a rigging.

The technical scheme of the invention is further improved as follows: the catch wheel device is rectangular, two L-shaped metal hooks are fixed at two thirds of the position of the wide side of the rectangle and perpendicular to the rectangular plane at two ends of the catch wheel device, the distance between the two L-shaped metal hooks is larger than 350mm, a plurality of bolts are evenly and spirally connected along the long side direction below the catch wheel device, the catch wheel device is installed on the outer side of the steel rail through the metal hooks, and the top end of each L-shaped metal hook and the bolts are respectively located on two sides of the steel rail.

Due to the adoption of the technical scheme, the invention has the technical progress that:

according to the lifting type rescue method, the lifting oil cylinders in the lifting machine are used for supporting the hangers on two sides, and the hangers are used for binding the bogie of the motor train unit and reducing the binding of personnel under the motor train unit; if the bogie of the train is twisted and two wheels cannot fall off the track at the same time, the bogie can be directly lifted and rerailed without being corrected; all the lifting and re-hoisting machines are arranged on the outer side of the car body, so that the car is convenient, quick, safe and reliable, the off-line bogie is lifted to re-orbit through the interaction of the two lifting oil cylinders, and the car body is automatically righted when being inclined and re-hoisted; when the derailed train body is close to the tunnel wall, the oil cylinder on one side is vertical, and the other side is jacked from inside to outside, so that the train can be reset; the invention uses the oil cylinder to jack and connect and fix at the car body top position (such as the positions of a lifting pin or a lifting position), can continuously move transversely with large distance by one-time installation, connects a rope between two oil cylinder bases and passes through the bottom of a steel rail, is not limited by the height of a off-line car body during rescue, and jacks and resets at one time; the rerailing device has the advantages of simple structure, few parts, light weight and convenient and safe rerailing method operation.
