Connection, multiple hook pawls are hinged by hinge with push rod device, and the described one end of hook pawl away from the push rod device is provided with
Overhead kick for catching on tuyere small sleeve.
Preferably, the push rod device includes connecting rod and the handle with being fixed on the connecting rod afterbody, the hook pawl and company
The head of bar is hinged.
Preferably, the elastic component is spring.
Preferably, the connecting rod and hook to be equipped with pawl on support column for installing the spring, the connecting rod and prop up
The length of dagger is more than the length for hooking pawl upper support column.
Preferably, the perpendicular setting of support column on the connecting rod.
Preferably, the length of the connecting rod is more than the length for hooking pawl.
The utility model proposes tuyere small sleeve disassembly mechanism, by setting multiple hook pawls, therefore tuyere small sleeve is taken in hook
More preferably, hook takes to be also easier to Shi Shouli.In addition, by the continuous action of elastic component, during handle is pulled, it is ensured that multiple to hook
All the time maximum angle is opened between pawl, will not be broken off relations.In addition, this tuyere small sleeve disassembly mechanism its is simple in construction, easy realization and
It is easy to use and reliable, to reducing the blast furnace staying time, improve its productivity ratio very meaningful.

Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.
Embodiment
It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model
Utility model.
It should be noted that in description of the present utility model, term " transverse direction ", " longitudinal direction ", " on ", " under ", " preceding ",
The orientation or position relationship of the instruction such as " rear ", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on
Orientation shown in the drawings or position relationship, are for only for ease of description the utility model and simplify description, are not to indicate or dark
Specific orientation must be had, with specific azimuth configuration and operation by showing the device or element of meaning, therefore it is not intended that right
Limitation of the present utility model.
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 pawls 2 on push rod device head（It is multiple to refer at least two hook pawls 2）And connection hooks pawl 2 and the elastic component of push rod device,
Wherein,
Each hook pawl 2 is correspondingly arranged an elastic component, and the two ends of elastic component are fixedly connected with push rod device and hook pawl 2 respectively,
Multiple hook pawls 2 are hinged by hinge with push rod device, and hooking the one end of pawl 2 away from push rod device and being provided with is used to catch on tuyere small sleeve
6 overhead kick.
Specifically, in the present embodiment, push rod device includes connecting rod 4 and the handle 5 with being fixed on the afterbody of connecting rod 4, hooks
The head of pawl 2 and connecting rod 4 is hinged.By setting handle 5, so as to facilitate the hand-held push rod device of user.
In the present embodiment, elastic component is spring 1.The support column for installing spring 1 is equipped with connecting rod 4 and hook pawl 2
3, the length of the upper support column 3 of connecting rod 4 is more than the length for hooking the upper support column 3 of pawl 2.The perpendicular setting of support column 3 on connecting rod 4.
The length of connecting rod 4 is more than the length for hooking pawl 2.
Illustrated in the present embodiment so that two hook pawl 2 as an example.Two hook pawl 2 and are connected through the hinge in the one end of connecting rod 4, two
Individual hook pawl 2 staggers certain distance " s ", can opened with certain angle automatically by the pulling force effect of spring 1.It is provided with because hooking on pawl 2
Overhead kick, it is angular shape, and because tuyere small sleeve 6 is softer Cu materials, under pulling force " F " effect at handle 5, hooks pawl 2
Overhead kick can be embedded in the surface of tuyere small sleeve 6, it is to avoid releasing in unloading process.When dismantling tuyere small sleeve 6, first hooked multiple
Pawl 2 stretches into the cone-shaped inner hole of tuyere small sleeve 6, continues to push handle 5 forward, under the pulling force effect of spring 1, 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 backward, small set can firmly be caught on by hooking pawl 2.Persistently drag
Handle 5, until pulling down 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 difficult to break off relations.
The tuyere small sleeve disassembly mechanism that the present embodiment is proposed, by setting multiple hook pawls 2, therefore takes tuyere small sleeve 6 in hook
More preferably, hook takes to be also easier to Shi Shouli.In addition, by the continuous action of elastic component, during handle 5 is pulled, it is ensured that multiple
Maximum angle is opened all the time between hook pawl 2, will not be broken off relations.In addition, its simple in construction, the easy realization of this tuyere small sleeve disassembly mechanism
And it is easy to use and reliable, to reducing the blast furnace staying time, improve its productivity ratio very meaningful.
