Embodiment Construction

[0027] The detachable thermal insulation device of the present invention is a novel thermal insulation structure of a railway tank car, and has considerable advantages over the original thermal insulation device. The structure is composed of multiple insulation shell sections, and each insulation shell section includes upper and lower flaps. Each insulation shell is welded by the insulation shell plate and the ring frame. The heat-insulation shell plate overlaps the connection form of the lower heat-insulation shell plate to form a ring-shaped sealing structure, which effectively prevents rainwater from entering. In order to ensure the rigidity of the thermal insulation shell at the lap joint, angle iron supports along the longitudinal direction of the tank body are welded on the circumferential frame at the lap joint. There is a certain gap between the two adjacent sections of the insulation shell, the purpose of which is to reserve the working space for the bolt fasteners, a...

Abstract

The invention relates to a dismountable heat insulation device of a railway tank car. The dismountable heat insulation device comprises a heat insulation case, wherein the heat insulation case comprises a plurality of heat insulation case tube sections arranged in the length direction of a tank car tank body; each heat insulation casing tube section comprises an upper part and a lower part; each heat insulation casing tube section is detachably connected with the tank body through a connecting component; a gap is formed between the two adjacent heat insulation casing tube sections; the gap can meet the operation requirements of the connection component. The heat insulation device consists of the plurality of heat insulation casing tube sections; the installation is convenient; the local dismounting can be realized; the workload and the work intensity during the manufacturing and overhaul of the tank car can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of railway tank car manufacturing, and in particular relates to a detachable thermal insulation device for railway tank cars. Background technique [0002] At present, the railway tank car is the most important vehicle for transporting asphalt medium, and the insulation device is an important part of the tank car. The existing railway tank car insulation device is a non-detachable structure. All the insulation shells of this structure are directly welded on the support of the tank body, and each support is connected with the tank body inside and the insulation shell outside. In addition, it was found during the repair process of the tank car that the maintenance of the tank car with this structure was difficult. If the tank is overhauled, the insulation shell of the whole vehicle must be removed. Because the insulation shell is a thin plate with a thickness of 2 mm and welded to the support protruding from the tank b...
