[0007] Technical issues to be solved

[0008] The purpose of the utility model is to provide a precise tilting blast furnace airtight box device, which solves the problem raised in the above-mentioned background technology by setting a limit component. When the inspection port is repaired, the inspection port needs to be opened, but due to the influence of high temperature and the bolt fixing method adopted, when the inspection port is opened, the parts at the inspection port are still hot, and there is a possibility of accidental scalding of the operator.

[0009] Technical Solution

[0010] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0011] The utility model is a precise tilting blast furnace airtight box device, comprising:

[0012] The main body assembly includes a second limiting plate;

[0013] The limiting assembly includes a limiting column arranged inside the second limiting plate, a connecting plate connected to the outer surface of the top of the limiting column, a connecting buckle arranged on the upper surface of the connecting plate, and a movable column arranged inside the bottom end of the limiting column;

[0014] The heat reduction components are arranged in multiple groups and connected to the other end of the second limiting plate.

[0015] Furthermore, a mounting groove is provided inside the bottom end of the limiting column, a mounting shaft is connected inside the mounting groove, an outer surface of the mounting shaft is movably connected to the movable column, and a guide plate is connected to the outer surface of the movable column;

[0016] Wherein, the length of the guide plate is smaller than the diameter of the movable column;

[0017] Specifically, the installation groove is used to receive and install the installation shaft. Under the setting of the installation shaft, a pressing force can be applied to the movable column. When the movable column is vertically placed inside the installation groove, the limit column can be pulled out from the second limit plate. When the movable column is horizontally placed inside the installation groove, the limit column can be limited to the bottom end of the second limit plate. The guide plate facilitates changing the placement state of the movable column.

[0018] Further, the heat reduction component includes a storage box, a connecting pipe arranged on the top of the storage box, and a water inlet connected to the top of the connecting pipe;

[0019] Specifically, the water storage tank is used to store cold water. The cold water is transported from the water inlet and then passed through the connecting pipe to the interior of the storage tank.

[0020] Furthermore, a hinge is provided at the top of the water inlet, and a movable plate is connected to the surface of the hinge;

[0021] The length of the movable plate is longer than the length of the water inlet;

[0022] Specifically, with the setting of the hinge, it is convenient to apply an upward lifting force to the movable plate, so that the top of the water inlet is in an exposed state, which facilitates the transportation of water to the interior of the storage box.

[0023] Furthermore, a water outlet pipe is provided at the bottom end of the storage box, and a pipe cover is threadedly connected to the outer surface of the bottom end of the water outlet pipe;

[0024] Specifically, by removing the pipe cover from the water outlet pipe, cold water can be output from the interior of the storage box.

[0025] Furthermore, the main body assembly also includes a blast furnace airtight box body, an inspection port opened inside the blast furnace airtight box body, a mounting frame connected to the outer surface of the inspection port, a hinge arranged inside the mounting frame, and a fixing plate connected to the hinge surface;

[0026] Specifically, the main body of the blast furnace airtight box is used to control the tilting angle of the blast furnace to achieve the tilting operation of the blast furnace and the smooth outflow of molten iron. The hinge supports and installs the installation frame, and then supports and installs the fixed plate. The inspection port is set for checking the internal status of the maintenance device.

[0027] Furthermore, a sealing ring is connected to the inner surface of the fixing plate, a first limiting plate is provided on the top surface of the fixing plate, and a connecting hole is provided inside the first limiting plate;

[0028] The height of the first limit plate is higher than that of the second limit plate;

[0029] Specifically, with the setting of the sealing ring, the fixed plate and the installation frame are connected more tightly. When the first limiting plate and the second limiting plate overlap, the movable column is passed through the connecting hole to firmly fix the fixed plate on the outside of the installation frame.

[0030] Beneficial Effects

[0031] Compared with the prior art, the advantages of the present invention are:

[0032] 1. Under the setting of the installation axis, the utility model applies a pressing force to the limit column, so that the movable column is vertically placed inside the installation groove. By hooking, the connecting buckle is placed inside the hook, and the limit column can be easily picked out from the first limit plate and the second limit plate, avoiding close operation of workers and causing accidental physical injuries.

[0033] 2. Based on the first beneficial effect, with the use of the heat reduction component, by delivering cold water to the inside of the storage box, the temperature at the cooling inspection port can be accelerated under the action of the cold water, thereby facilitating the operation of the inspection port and greatly improving the efficiency of maintaining the device.

[0034] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
