High temperature hot delivery steel billet transportation special vehicle chassis

Abstract

The invention discloses a high temperature hot delivery steel billet transportation special vehicle chassis. The high temperature hot delivery steel billet transportation special vehicle chassis comprises a chassis component and a low-layer floor, a heat preservation thermal insulation layer assembly is arranged above the low-layer floor, and comprises a thermal insulation layer cross beam, a thermal insulation layer side beam, a thermal insulation layer support cross beam, a thermal insulation layer longitudinal beam and an upper-layer floor, the thermal insulation layer longitudinal beam is placed in the middle of the chassis and is welded to the thermal insulation layer cross beam, the thermal insulation layer cross beam and the thermal insulation layer support cross beam are assembled and welded into a simply supported beam structure, then the simply supported beam structure and the thermal insulation layer side beam are assembled and welded to form a frame-shaped grid beam structure, the frame-shaped grid beam structure is paved with the upper-layer floor, and a cavity formed by the whole frame-shaped grid beam structure is filled with a heat preservation material. The high temperature hot delivery steel billet transportation special vehicle chassis has a good heat preservation function, and the chassis is applicable to safe loading and transportation of a steel billet not higher than 700 DEG C in a steel enterprise; moreover, the thickness of the heat preservation material can be adjusted according to the temperature of the loaded and transported steel billet, therefore achieving safe loading and transportation of steel billets with different temperatures in all steel enterprises.

Description

technical field [0001] The invention belongs to the technical field of railway freight car transportation, and in particular relates to a special vehicle underframe for high-temperature hot-delivery billet transportation. Background technique [0002] In recent years, in order to meet the development needs of my country's metallurgical industry, various metallurgical enterprises have increased their demand for special rail vehicles. Among them, due to process layout reasons, some enterprises need to transport high-temperature continuous casting billets over long distances between processes. With the gradual deepening of energy conservation and emission reduction in the metallurgical industry, in order to reduce the energy required for billet reheating and to meet the environmental fire safety requirements along the line, new requirements for heat preservation and airtightness have been put forward for billet transport vehicles. [0003] The existing underframe for steel bil...

AI Technical Summary

Problems solved by technology

[0003] The existing underframe for steel billet transport vehicles, in which the beam is a B-shaped steel structure, and the side beam is a channel steel structure, its bearing capacity, stiffness and strength are not high, and it often appears concave deformation to varying degrees during long-term use. In terms of capacity, the heat insulation effect is poor, and the heat preservation performance is not high
