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...

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...
