Problems solved by technology
At present, after heavy tank off-line accidents occur in many large iron and steel enterprises in China, the average rescue time is dozens of hours, some as long as more than 60 hours, which seriously affects the production and economic benefits of iron and steel making systems of various enterprises
For the accident rescue of 320-ton torpedo tanks, the four hoisting points set by the original car were used for hoisting. Due to the constraints of the railway limit and the structure of the car body, the off-line hoisting position set by the original car was unreasonable. The box is too close, and the recovery equipment and the bogie part conflict with the bogie during the recovery and lateral movement reset, and the fulcrum of the jacking pick is difficult to stabilize, which makes it very difficult to recover the accident

Embodiment Construction
[0016] The technical solution of the present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0017] This example is a 320-ton torpedo-type mixed iron car, refer to the attached figure 1 , which is a schematic diagram of rescuing the off-line side of the torpedo-type mixed-rail car. The resuscitation method of the present invention is carried out according to the following steps: a. determine the off-line position and the number of axles of the vehicle; The center of gravity of the frame on the side 1 supports an upright hydraulic pick. The upright hydraulic pick is the main jack 2. First, support the box-shaped backing plate 4. Place the roller-type sliding plate 3 on the box-shaped backing plate, and then place the main jack 2. ; d. Support upright hydraulic pick 6 and traverse hydraulic pick 7 at the end of the draw beam, and at the same time place a box-shaped backing plate at the end of the draw beam 5, pl...

The invention relates to a method for retrieving off-line accidents of a torpedo type car, belonging to the technical field of off-line retrieval of railway vehicles in metallurgy industry. The technical scheme is as follows: an upright hydraulic pick which is a main top pick is supported at a frame gravity position above the off-line side; an upright hydraulic pick and a translation hydraulic pick are supported at the end of a traction beam; roller type sliding discs are placed below the hydraulic picks; the main top pick is used for jacking the frame and a bogie at the off-line part; and through the upright hydraulic pick and the translation hydraulic pick supported at the end of the traction beam, an off-line wheel pair is rapidly and flexibly retrieved in place. The method of the invention has the effects of: rapidly retrieving the off-line torpedo type car in place, avoiding great economical loss caused by overlong accident retrieval which influences the normal production and causes solidification of molten iron in a tank, being suitable for the retrieval of various forms of accidents under various environments, having outstanding advantage in the narrow and small areas wherethe large-scale hoisting equipment cannot enter. The method has the characteristics of being simple in operation, safe, reliable, convenient, rapid and the like.
Description
technical field [0001] The invention and a method for rescuing an off-line accident of a torpedo-type mixed railway car belong to the technical field of rescuing off-line railway vehicles in the metallurgical industry. Background technique [0002] At present, the 320-ton torpedo-type mixed iron car is a new type of large-scale iron transportation equipment with the highest technical content and the largest tonnage in domestic metallurgical enterprises. Due to its huge size (25.89 meters in length, 288 tons in weight, 320 tons in load, and a total weight of more than 600 tons), when running on some curved road sections, because the car belongs to high-temperature and heavy-duty liquid metal transportation, once an off-line accident occurs How to quickly rescue and reduce the impact on production is a major issue directly related to the production of enterprises, and it is also a major technical issue for large domestic iron and steel enterprises. At present, after heavy tan...
