Problems solved by technology

[0002] Railway traffic accidents are vicious accidents that disrupt the normal order of railway transportation. Traditional straight-top and lateral-moving rescue and recovery equipment can complete the rescue of accident vehicles in straight lines or turnouts, but most vehicles are off-line in the curved part of the line. Due to the height difference between the outer rail and the inner rail of the curve (the maximum height difference can reach 175mm), when the wheel set rerails, the outer wheel set is first in contact with the rail, while the inner wheel set is still in the suspended state. When forced to rerail, the car body will inevitably tilt, which will cause the lifting equipment to slip or fly sideways, causing major safety accidents. The accident car cannot be rerailed, and it will also endanger personal safety.
In addition, the power grid must be dismantled when using a crane for rescue, which is a large and cumbersome operation

Embodiment 1

[0029]Such asFigure 1 to Figure 4 As shown, the cylinder base 4 is fixedly installed on the ground near the inclined car body. According to the site conditions, after selecting the appropriate length of the hook chain 6, insert the appropriate chain link into the chain lock block 5, and the corresponding chain link is longitudinally snapped in Groove two 10, clamp the adjacent chain link laterally into groove nine, and insert the pin into the pin hole of the chain lock block 5 to prevent the hook chain 6 from detaching, so that the hook chain 6 and the cylinder base 4 can be detached Type movable connection; fixedly connect the end of the hook chain 6 with the special hook 7 to the rail; hinge the centralizing cylinder 3 with the cylinder base 4, and after the special ejector rod 1 and the spherical ejector rod 2 are universally hinged, the special ejector rod 1 On the side beam 11 of the car body on the inclined side of the accident car, the righting cylinder 3 is connected to the...

Embodiment 2

[0031]In the first embodiment, when the hydraulic lifting equipment is used to carry out the vertical and horizontal movement rerailing operation on the car body, when the wheel set is aligned with the rail 12 and dropped, the outer wheel set contacts the curved outer rail first, and the outer wheel set is set to the rail. When the inner wheel set is suspended relative to the inner rail, the present invention is laid in the same way as in the first embodiment. After laying, the righting cylinder 3 is slowly raised under the action of the high-pressure pumping station. At this time, the hydraulic lifting equipment is disassembled and withdrawn. At this time, the righting cylinder 3 is controlled to slowly descend until the inner wheelset is in full contact with the inner rail, and the invention is withdrawn and the rescue is over.

Abstract

The invention relates to a curve rescue device. The curve rescue device structurally comprises a special jacking, a spherical ejector rod, a centralizing oil cylinder, an oil cylinder base, and a hookchain. The adopted centralizing oil cylinder has the advantages of being light in weight, long in service life, large in jacking force, safe and reliable; the oil cylinder base and a steel rail are in flexible connection, installation is easy and rapid, and carrying and storage are convenient; meanwhile, the oil cylinder base is provided with a chain locking block, so rapid, accurate, adjustableand convenient connection between the hook chain and the oil cylinder base is achieved; and at the same time, the chain locking block fixes the hook chain through a plug pin, the length of the chain can be adjusted at will according to actual rescue situation, and meanwhile safety and reliability of the operation process are guaranteed.

Description

Technical field[0001]The invention relates to the technical field of rail rescue, in particular to a curved rescue device.Background technique[0002]Railway traffic accidents are malignant accidents that disrupt the normal order of railway transportation. Traditional vertical-top and horizontal-moving rescue and recovery equipment can complete the rescue of accident vehicles under working conditions such as straight lines or turnouts. However, most vehicles are off-line in the curved part of the line. Due to the height difference between the curved outer rail and the inner rail (the maximum height difference can reach 175mm), when the wheelset is rerailed, the outer wheelset is in priority contact with the steel rail, while the inner wheelset is still in a suspended state. When forcibly rerailing the car body will inevitably tilt, which will cause the lifting equipment to slip or fly sideways, causing a major safety accident. The accident car cannot be rerailed and personal safety wi...
