[0002] In the converter production process, the smoke hood will be damaged, water leakage due to high temperature, sticky steel, sticky slag, smoke dust erosion and other factors, and needs regular maintenance. The current use of inclined ladder, more for general type, not for the special environment and operation demand design of converter maintenance smoke hood, there is no matching between the ladder body structure and the smoke hood surrounding space, leading to installation inconvenience and large space occupation, poor safety. At the same time, the existing inclined ladder also has the security risks such as anti-skid and anti-falling, in the high temperature, humid and narrow space converter maintenance environment, easy to cause safety accidents, affect the maintenance personnel personal safety and maintenance work efficiency. SUMMARY

[0003] The utility model aims at providing a special inclined ladder for converter maintenance smoke hood, which can adapt to the surrounding space of the converter smoke hood, enhance safety protection, improve maintenance efficiency and safety, and solve the problems in the background art.

[0004] The technical scheme of the utility model is:

[0005] A special inclined ladder for converter maintenance smoke hood, comprising an inclined ladder section, a platform section, a anti-falling hook, a smoke hood, a converter and a supporting foot, the inclined angle of the inclined ladder section is 45°-60°, the lower end of the inclined ladder section is provided with a supporting foot, the upper end of the inclined ladder section is connected with the platform section to form a whole, and the platform section is provided with an anti-falling hook connected with the converter mouth.

[0006] Further, the platform section is also provided with a tool storage area composed of grating plates.

[0007] Further, a diagonal support is arranged between the platform section and the inclined ladder section.

[0008] Further, the inclined ladder section and the platform section are both provided with spaced protective railings, and connecting crossbars serving as handrails are arranged between the protective railings.

[0009] The utility model has the advantages that the utility model can adapt to the surrounding space of the converter smoke hood, enhance safety protection, improve maintenance efficiency and safety. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 1 It is the utility model front view;

[0011] Fig. 2 It is the utility model use state schematic drawing;

[0012] In the figure: italic segment 1, platform segment 2, inclined support 3, anti-falling hook 4, smoke cover 5, converter 6, support foot 7, protective rail 8, crossbar 9, footboard 10, tool storage area 11. DETAILED DESCRIPTION

[0013] The utility model will be further described by examples in connection with the drawings.

[0014] Refer to the drawings Figs. 1-2 A special inclined ladder for converter maintenance smoke cover contains inclined ladder segment 1, platform segment 2, anti-falling hook 4, smoke cover 5, converter 6 and support foot 7, the inclination angle of inclined ladder segment 1 is 45 °-60 °, the lower end of inclined ladder segment 1 is equipped with support foot 7, the upper end of inclined ladder segment 1 is connected with platform segment 2 to form a whole, platform segment 2 is equipped with the anti-falling hook 4 connected with the converter 6 furnace mouth.

[0015] In this example, refer to the drawings Figs. 1-2 The main body structure of the special inclined ladder adopts high-strength alloy steel, and the surface is hot-dip galvanized to enhance corrosion resistance and high-temperature resistance, suitable for high-temperature and humid environment of converter maintenance.

[0016] The inclination angle of the inclined ladder segment 1 is 45 °, which is convenient for personnel to climb and equipment to dock.

[0017] The inclined ladder segment 1 and platform segment 2 are both equipped with protective rail 8 and footboard 10 arranged at intervals, and connecting crossbar 9 is arranged between protective rail 8 as handrail. The footboard 10 adopts patterned steel plate, and the surface convex pattern increases the friction force to prevent personnel falling and objects sliding.

[0018] The platform segment 2 is also provided with a tool storage area 11 composed of grating plates, which is ventilated and anti-skid.

[0019] When installing, first adjust the support foot 7 at the lower end of the inclined ladder segment 1 to the appropriate height, and stably place it on the ground, then firmly connect the anti-falling hook 4 at the top end of the platform segment 1 with the furnace mouth of the converter 5.

[0020] Use: when maintenance personnel climb, hold the handrail with both hands, step up and down steadily, and after reaching the platform segment 2, tools can be taken from the tool storage area 11.

[0021] Maintenance: regularly check whether the connection of each part of the ladder is loose, especially the anti-falling hook 4 and the support foot 7, check the wear of the patterned steel plate, the deformation of the protective rail and the peeling of the hot-dip galvanizing layer, and repair or replace the damaged parts in time.
