Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
through the matching of the graphite packing and the castable frame, a better sealing effect is realized.
The door plate is easy to open and close, labor cost is saved, and working efficiency is improved.
Simple structure, processing convenience, practicality are strong, application scope is wide.
Preferably, the present invention further provides:
a U-shaped plate is arranged between the door locking fixing support and the long strip plate, a through hole matched with the pin shaft is arranged at the joint of the U-shaped plate and the long strip plate, a threaded hole is formed in the bottom surface of the U-shaped plate, a jackscrew is arranged in the threaded hole, and a rotating handle is arranged at one end of the jackscrew; further locking the seal.
The door panel fixing frame is provided with a door handle; the door is conveniently opened and closed.
An anchoring piece is welded in the castable frame and the castable is filled in the castable frame; the castable frame is prevented from being deformed due to high temperature.
Drawings
Fig. 1 is a schematic structural view of a door closing state of an embodiment of the present invention;
fig. 2 is a schematic structural view of the door opening state of the embodiment of the present invention.
In the figure: a base plate 1; a door panel 2; a door panel fixing frame 3; a pin shaft 4; a door lock fixing bracket 5; a top thread 6; a rotating handle 7; a U-shaped plate 8; a door shaft fixing bracket 9; a door shaft 10; a lock nut 11; a graphite packing 12; a door handle 13; a castable frame 14; a strip 15.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 and 2, a pre-heater manhole door comprises a bottom plate 1 and a door plate 2, wherein an opening is arranged in the middle of the bottom plate 1, mounting grooves are formed in the bottom plate around the opening, a graphite packing 12 is mounted in each mounting groove, a door shaft fixing support 9 is welded on the bottom plate 1 near one edge, door locking fixing supports 5 are welded on the bottom plate 1 near the other three edges, through holes are formed in the door shaft fixing supports 9 and the door locking fixing supports 5, a door shaft 10 is connected to each door shaft fixing support 9, a door plate fixing frame 3 is connected to each door shaft 10, the door plate 2 is connected to each door plate fixing frame 3, a strip plate 15 corresponding to each door locking fixing support 5 is welded to each door plate fixing frame 3, a through hole is formed in each strip plate 15, each door locking fixing support 5 is connected to each strip plate 15 through a pin shaft 4, and a door handle 13 is welded on the edge of each door plate fixing frame 3, which is opposite to each door shaft 10, a castable frame 14 which is adaptive to a graphite packing 12 in the mounting groove is arranged on the inner side surface of the door plate 2, an anchoring piece is welded in the castable frame 14 and is filled with castable, a U-shaped plate 8 is arranged between the door locking fixing support 5 and the strip plate 15, a through hole which is adaptive to the pin shaft 4 is arranged at the joint of the U-shaped plate 8 and the strip plate 15, a threaded hole is formed in the bottom surface of the U-shaped plate 8, a jackscrew 6 is arranged in the threaded hole, and a rotating handle 7 is arranged at one end of the jackscrew 6; this device is installed specially on the pre-heater, supply the people to get into or outside inspection usefulness, weld anchor assembly and beat the pouring material in pouring material frame 14 before the installation, prevent that the manhole door is because of high temperature deformation, graphite packing 12 is tightly ann and is effectively sealed in the fixed slot, graphite packing 12 has high temperature resistant characteristic in addition, can not damage because of the high temperature in normal production, jackscrew 6 and twist grip 7 can be with door locking, it is sealed well to avoid causing the hourglass material problem of leaking out, the design of door-hinge 10 and twist grip 7 can make things convenient for the manhole door switch, only need alone can be with the manhole door switch when overhauing, not only use manpower sparingly but also safe and reliable.
