Piece number in figure: 1- spring, 2- hook pawl, 3- support column, 4- connecting rod, 5- handle, 6- tuyere small sleeve, the air port 7-
Middle set.
The embodiments will be further described with reference to the accompanying drawings for the realization, the function and the advantages of the object of the present invention.
Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that in the description of the present invention, term " transverse direction ", " longitudinal direction ", "upper", "lower", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of description of the present invention and simplification of the description, and is not the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to limit of the invention
System.
Referring to Figures 1 and 2, in this preferred embodiment, a kind of tuyere small sleeve disassembly mechanism, including push rod device, be installed on
Multiple hook pawl 2(on push rod device head are more to refer to that at least two hook pawls 2) and connection hook the elastic component of pawl 2 and push rod device,
Wherein,
Each hook pawl 2 is correspondingly arranged an elastic component, and the both ends of elastic component are fixedly connected with push rod device and hook pawl 2 respectively,
Multiple hook pawls 2 are hinged by hinge and push rod device, hook pawl 2 and are equipped with far from one end of push rod device for catching on tuyere small sleeve
6 overhead kick.
Specifically, in the present embodiment, push rod device include connecting rod 4 and with the handle 5 that is fixed on 4 tail portion of connecting rod, hook
Pawl 2 and the head of connecting rod 4 are hinged.By the way that handle 5 is arranged, so that user be facilitated to hold push rod device.
In the present embodiment, elastic component is spring 1.The support column for installing spring 1 is equipped on connecting rod 4 and hook pawl 2
3, the length of 4 upper support column 3 of connecting rod is greater than the length for hooking 2 upper support column 3 of pawl.The perpendicular setting of support column 3 on connecting rod 4.
The length of connecting rod 4 is greater than the length for hooking pawl 2.
It is illustrated by taking two hook pawls 2 as an example in the present embodiment.Two hook pawls 2 are connected by a hinge in 4 one end of connecting rod, and two
A hook pawl 2 is staggered certain distance " s ", can automatic opened with certain angle by the pulling force effect of spring 1.It is provided on pawl 2 because hooking
Overhead kick is angular shape, and since tuyere small sleeve 6 is softer Cu material, under pulling force " F " effect at handle 5, hooks pawl 2
Embeddable 6 surface of tuyere small sleeve of overhead kick, avoid loosening in disassembly process.When dismantling tuyere small sleeve 6, first by multiple hooks
Pawl 2 protrudes into the cone-shaped inner hole of tuyere small sleeve 6, continues to push handle 5 forward, under 1 pulling force effect of spring, hooks pawl 2 and is close to taper
Bore area, when the hook stretching tuyere small sleeve 6 of pawl 2 is outer, then handle 5 of shaking hands backward, small set can securely be caught on by hooking pawl 2.Persistently drag
Knob handle 5, until removing tuyere small sleeve 6.When pulling handle 5, connecting rod 4 can suitably be lifted to an angle " θ ", make pulling force
" F " is overlapped with air port center line, is pulled effect more preferably and is not easy to break off relations.
The tuyere small sleeve disassembly mechanism that the present embodiment proposes by the way that multiple hook pawls 2 are arranged, therefore takes tuyere small sleeve 6 in hook
Shi Shouli is more preferable, and hook, which takes, to be also easier to.In addition, during pulling handle 5, being guaranteed multiple by the continuous action of elastic component
It hooks and opens maximum angle always between pawl 2, will not break off relations.In addition, its structure of this tuyere small sleeve disassembly mechanism is simple, easy to accomplish
And it is easy to use and reliable, to the blast furnace staying time is reduced, it is very significant to improve its productivity.
Present invention further propose that a kind of method for dismounting of tuyere small sleeve disassembly mechanism.
In this preferred embodiment, a kind of method for dismounting based on above-mentioned tuyere small sleeve disassembly mechanism, comprising the following steps:
Multiple hook pawls are sent into the cone-shaped inner hole of tuyere small sleeve by push push rod device forward, under the action of the elastic member, more
A surface for hooking pawl and being close to tuyere small sleeve cone-shaped inner hole；
When multiple hook pawls stretch out tuyere small sleeve, pulling-pushing rod device, makes multiple overhead kicks for hooking pawl securely catch on wind backward
The small set of mouth；
Continue to pull push rod device outward, until removing tuyere small sleeve.
Specifically, when pulling push rod device outward, connecting rod, which is lifted up an angle, is overlapped it with air port center line
Effect is pulled to improve.It is not easy to break off relations at this point, hooking pawl.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
