[0002] At present, torpedo type ladle cars are mostly used for transporting molten iron in metallurgical enterprises, but the traditional torpedo type ladle car usually has no cover on the tank opening, and the temperature of the molten iron inevitably decreases and the emission of smoke dust is serious during transportation, which pollutes the environment. In order to effectively reduce the heat loss of the molten iron and the emission of smoke dust, there are many cover devices of the torpedo type ladle car with various transmission forms in the prior art, but the heat preservation cover in the existing cover equipment has the following disadvantages: (1) poor heat resistance and easy deformation, short service life; (2) poor heat preservation performance, and the heat preservation layer is easy to fall off; (3) difficult to control the installation and positioning of the heat preservation cover; (4) the heat preservation cover and the cover mechanism are mostly welded or bolted, which causes difficulty in inspection, maintenance and replacement. The above disadvantages affect the energy saving and emission reduction of the ladle car cover device in the production of steel enterprises, and restrict the popularization and application of the ladle car heat preservation cover device. SUMMARY

[0003] In view of the problems of the heat preservation cover of the ladle car in the background art, such as poor heat resistance and easy deformation, short service life, difficult to control the positioning deviation of the heat preservation cover, and difficult to disassemble and install when the heat preservation material is inspected and replaced, the present application provides a reinforced quick-mounting type ladle car heat preservation cover, which has high strength, good high temperature resistance and is not easy to deform, and can be automatically positioned and quickly disassembled and replaced.

[0023] like Figures 1 to 3 As shown, the present invention discloses a reinforced, quick-installable insulation cover for a hybrid iron car. The insulation cover 10 includes an integral, annular insulation cover top plate 13. An integral insulation cover outer ring 11 and an integral insulation cover inner ring 12 are spaced apart on the same side of the insulation cover top plate 13, with an overall circular insulation layer 16 provided at the inner edge. The insulation cover outer ring 11, the insulation cover inner ring 12, and the insulation cover top plate 13 are provided with a V-shaped annular groove positioning structure 14. In this embodiment, the insulation cover top plate 13 may also be provided with a plurality of mounting lugs 17 on the other side of the insulation cover outer and inner rings 11 and 12 to facilitate rapid assembly and disassembly of the insulation cover 10. The insulation cover 10 is usually used in conjunction with the insulation cover seat 20. The insulation cover seat 20 includes a circular ring structure made of a steel pipe. The insulation cover seat 20 is adapted to the V-shaped ring groove positioning structure 14 of the insulation cover 10, which facilitates the rapid self-positioning installation of the insulation cover 10 and the insulation cover seat 20. A connecting piece 30 is provided on one side of the insulation cover seat 20 for connecting to a covering mechanism, etc.

[0024] During quick installation, the lifting lugs 17 are directly hung with a sling, and the thermal insulation cover 10 is lifted by a crane. The V-shaped ring groove structure 14 of the thermal insulation cover 10 is dropped onto the thermal insulation cover seat 20 by the weight of the thermal insulation cover to complete the quick installation.

[0025] During quick disassembly, since the thermal insulation cover 10 is designed to utilize the V-shaped ring groove structure 14 and is positioned by its own weight, the thermal insulation cover 10 can be directly lifted upward by hanging the mounting lugs 17 with a sling to complete the quick disassembly.

[0026] In this embodiment, the V-shaped ring groove positioning structure 14 includes a plurality of first positioning ribs 141 evenly arranged between the outer ring 11 of the insulation cover and the top plate 13 of the insulation cover, and a plurality of second positioning ribs 142 evenly arranged between the inner ring 12 of the insulation cover and the top plate 13 of the insulation cover and corresponding one to one to each first positioning rib 141. The corresponding sides of each corresponding first positioning rib 141 and second positioning rib 142 are inclined toward each other and form a V-shaped groove. The purpose of designing the first positioning ribs 141 and the second positioning ribs 142 in this embodiment is, firstly, to enhance the strength of the insulation cover 10 by means of the positioning ribs, and to prevent the insulation cover 10 from being deformed due to high temperature, etc., and secondly, to utilize the V-shaped grooves formed by the corresponding first positioning ribs 141 and the second positioning ribs 142 to form a large V-shaped ring groove positioning structure, which is convenient for the installation of the insulation cover 10 on the insulation cover plate 20. Moreover, this V-shaped ring groove positioning structure has a simple structure and accurate positioning, and is very easy to set on the insulation cover. The specific shape, size and spacing of the corresponding first positioning ribs 141 and the second positioning ribs 142 can be designed according to the steel pipe size of the insulation cover seat 20, etc., so as to achieve precise positioning. Furthermore, the insulation cover outer ring 11, the insulation cover inner ring 12, the insulation cover top plate 13 and the V-shaped ring groove positioning structure 14 can be preferably made of G10 steel plate, which effectively ensures the strength of the insulation cover 10 and increases the service life of the insulation cover.

[0027] In this embodiment, the outer ring 11 of the heat preservation cover can also be arranged to be inclined toward the outside of the heat preservation cover top plate 13 to improve the disassembly and assembly effect of the heat preservation cover 10.

[0028] In this embodiment, an insulation layer anchor 15 is provided on the insulation layer 16. The insulation layer anchor 15 can be in a "well" shape and can be made of stainless steel. The insulation layer 16 is made of aluminum silicate fiber insulation material and is arranged in sheets in sequence in the height direction of the insulation cover 10. The insulation layer anchor 15 is embedded and installed on the insulation layer 16. Through the above design, the insulation layer can be strengthened and the service life of the insulation cover can be extended.
