At present, the window assembly of air-supply apparatus of blast furnace substantially all adopts wedgeplate-type to connect, namely will spy on port lid by wedge and air-supply arrangement window flange connects, what spy on that the seal form of port lid and window flange adopts is the asbestos packing structure, because of the air-supply apparatus of blast furnace pressure of air supply bigger, this kind mechanism is easy in use to occur to run wind, phenomenon that temperature is high, also brings bigger physical demands to service worker simultaneously in Installation and Debugging.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of air-supply apparatus of blast furnace to spy on the syndeton of port lid and window flange.
The utility model adopts following technical scheme:
A kind of air-supply apparatus of blast furnace is spied on the syndeton of port lid and window flange, comprises and spies on the spinning chuck that port lid is connected, and the window flange that is connected with the window flange is characterized in that: the spinning grab that revolves on card platen and the window flange spins.
Adopt the utility model of technique scheme compared with prior art, spinning chuck and spinning grab spin; This structure formation has advantages such as installation and maintenance are simple, use properties is reliable, sealing effectiveness is tight, can satisfy the blast furnace staying time, saves maintenance cost.
Preferred version of the present invention is:
The spinning chuck is provided with claw, and claw and spinning grab spinning are fastening.
Be respectively equipped with gradient structure on spinning grab and the claw; The gradient face tabling of spinning grab and claw.
The spinning chuck is provided with projection, and the window flange is provided with groove; Projection embeds in the groove; Be respectively equipped with the V-seal groove on groove and the projection.
Projection and groove are gone up set V-seal groove and are staggered layout.
Be equipped with in the groove and coat pad.
Claw places on the external diameter of spinning chuck.
Gradient structure on described spinning grab and the claw is 1:10.
Described spinning chuck with spy on port lid and be connected a side and be provided with and be sleeved on the support ring of spying on the port lid shoulder, on the elbow body that connects on the window flange web plate is housed, support ring is hinged by connection handle and web plate.

Embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail:
A kind of air-supply apparatus of blast furnace is spied on the syndeton of port lid and window flange, referring to accompanying drawing 1 to accompanying drawing 7, among the figure: spy on port lid 1, support ring 2, spinning chuck 3, pushing out ring 2, spinning chuck 3, elbow body 4, web plate 5, window flange 6, bearing pin 7, connection handle 8, shoulder 9, projection 10, groove 11, V-seal groove 12, coat pad 13, connect support 14, claw 15, spinning grab 16.
In the present embodiment, spinning chuck 3 with spy on port lid 1 and be connected, window flange 6 is connected with elbow body 4, revolves card platen 3 and spins with spinning grab 16 on the window flange 6.
Spinning chuck 3 is provided with claw 15, and claw 15 is fastening with spinning grab 16 spinning.
Be respectively equipped with gradient structure on spinning grab 16 and the claw 15; Both gradient faces of spinning grab 16 and claw 15 closely are connected.
Spinning chuck 3 is provided with projection 10, and window flange 6 is provided with groove 11; Projection 10 embeds in the groove 11; Be respectively equipped with V-seal groove 12 on groove 11 and the projection 10; Be equipped with in the groove 14 and coat pad 13.
Spinning chuck 3 is provided with support ring 2 with spying on the side that port lid 1 is connected, and support ring 2 is sleeved on the shoulder 9 of spying on port lid 1, and on the elbow body 4 that is connected on the window flange 6 web plate 5 is housed, and support ring 2 is hinged by connection handle 8 and web plate 5.
Connection handle 8 and web plate 5 are set to two respectively, and wherein two connection handles 8 connect by connecting support 14.
When repair and maintenance, make and spy on port lid 1 at support ring 2 internal rotation, screw out from window flange 6, will spy on the outside that port lid 1 rotates to elbow body 4 by support ring 2 and bearing pin 7.
The structure formation of present embodiment has advantages such as installation and maintenance are simple, use properties is reliable, sealing effectiveness is tight, in case when meeting the blast furnace staying maintenance, saved the time that workman in the past carries inspection hole cover greatly, only needing to spy on port lid 1 rotates on one side and gets final product, thereby shortened the blast furnace staying time, saved maintenance cost.
