Railway transportation vehicle for large tubular goods and method for loading large tubular goods

Abstract

The invention relates to a railway transportation vehicle for large tubular goods and a method for loading large tubular goods, comprising four bogies, two small underframes, a bearing underframe, two rows of bearing cushion blocks, and two rows of guide pulleys, wherein the four bogies are arranged along a railway line in sequence, a coupler and draft gear is arranged on the bogies at the outer ends of two sides respectively, and each bogie is provided with a brake device; two ends of each small underframe are respectively connected on two bogies at each side; two ends of the bearing underframe are respectively connected on the two small underframes at two sides; the two rows of bearing cushion blocks are respectively arranged at two sides of the top of the bearing underframe at intervals along the axial direction, and an end part compressing device is respectively arranged at two sides of the two rows of bearing cushion blocks; the two rows of guide pulleys are respectively arranged at two sides of the bottom of the bearing underframe at intervals along the axial direction, and compressing screw rods are respectively arranged at the bottom and two side walls of the bearing underframe between the two groups of guide pulleys. The railway transportation vehicle is applicable to railway transportation of the large tubular goods, such as the railway transportation of a barrel body of a hydrogenation reactor, a barrel of a large boiler and the like.

Description

technical field [0001] The invention relates to a railway transport vehicle and a method for loading goods by using the railway transport vehicle, in particular to a railway transport vehicle for large cylindrical goods and a method for loading large cylindrical goods. Background technique [0002] Large-scale cylindrical cargo generally includes a cylinder body and an end cover, and has a large shape and weight. For example, the hydrogenation reactor is an important part of heavy chemical equipment, with a cylindrical structure and a weight of about 300-350 tons. When using railway transport vehicles to transport large cylindrical goods, it is generally possible to use long cargo vehicles such as D30 for loading and transportation. However, the load-bearing surface of the existing long freight wagon has a height limit, and some large-diameter cylindrical goods may exceed the limit of the rolling stock after being loaded. At present, the use of different levels of overrun ...

AI Technical Summary

Problems solved by technology

However, the height of the bearing surface of the existing long freight wagons is limited, and some large-diameter cylindrical goods may exceed the limit of the rolling stock after being loaded.

At present, the use of different levels of overrun transportation for different grades of large cylindrical goods can effectively solve the problem of large cylindrical goods exceeding the limit of rolling stock, but this will cause a significant increase in transportation costs
