Description
Technical Field
The utility model relates to a driving accident rescue equipment test technical field among the rail transit particularly, relates to a hydraulic pressure rerailer test system.
Background
The hydraulic rerailer is one of necessary equipment for railway traffic accident rescue, and plays an important role in accident rescue; especially for large road maintenance machines, it is stipulated that each vehicle must be equipped with a hydraulic rerailer. The hydraulic rerailer becomes a main rescue tool for vehicle accident rescue in rail transit, and the reliability and quality stability of the rerailer affect whether vehicle accident rescue can be smoothly carried out. Quality inspection is crucial to guarantee railway transportation safety, at present, the quality of hydraulic rerailers is uneven, and in the process of road rescue, secondary accidents caused by failure of too many rescue devices occur to cause rescue failure. Therefore, it is important to check the quality of the hydraulic rerailer.
At present, the existing hydraulic rerailer is mainly checked in two ways: the method is characterized in that a real locomotive or vehicle is adopted for on-site simulation drilling, the real rescue process of the hydraulic rerailer can be effectively simulated, but the method is limited by a tested locomotive body and test site conditions, the functionality of the hydraulic rerailer can only be verified, the rated design capability (such as the maximum jacking load and jacking distance, the maximum transverse moving thrust, the maximum transverse moving distance and the like) of the hydraulic rerailer cannot be verified, and the rerailer verified by the method can have the risk of rescue failure when a large-tonnage locomotive is rescued in the real rescue process. And the second mode is that the vertical jacking load and the transverse moving load of the oil cylinder are verified by verifying the output load of the oil cylinder of the hydraulic rerailer in a laboratory, and the current laboratory means cannot simulate the complete process of rescue of driving accidents of the hydraulic rerailer, so that the risk that the expected function cannot be realized in the actual rescue process occurs. In order to verify the quality of the hydraulic rerailer more efficiently, reliably and fully, a universal hydraulic rerailer test system is needed to be developed so as to ensure the reliability and safety of the operation of all mechanical parts of the rerailer.

The two hydraulic rerailers are very common in the field of railway rescue. The two rerailers can realize the functions of jacking and rerailing the overturned locomotive (or vehicle), but when the two rerailers work, the motion tracks of the rescued locomotive (or vehicle) are different: for the herringbone rerailer, a rescued locomotive (or vehicle) needs to simultaneously operate a left oil cylinder and a right oil cylinder in the jacking process, so that the locomotive (or vehicle) moves to reset onto a steel rail according to an approximate arc track to realize the rescue action; the straight-jacking and transverse-moving type rerailer adopts the rerailing principle that a capsizing locomotive (or a vehicle) is jacked up through a vertical oil cylinder, then translated to the position above a steel rail through a transverse oil cylinder, and then horizontally placed on the steel rail, so that rerailing is realized. The interfaces and the sizes of the two hydraulic rerailers are not uniform, and the designed test system can meet the test requirements of the two hydraulic rerailers at the same time.
