Specific embodiment
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
It is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to the utility model
The range of protection.
Below in conjunction with attached drawing, technical solution provided by the embodiment of the utility model is described in detail.
As shown in Fig. 1, be provided with air port on the side wall of blast furnace, air port include from outer to inner sequentially connected big set X1,
Middle set X2 and small set X3.One end of big set X1 is located at the outside of blast furnace, and the other end is sleeved on one end of middle set X2, small set X3's
One end is set in the other end of middle set X2, and the other end protrudes into blast furnace.Hot wind sequentially passes through big set X1, middle set X2 and small set X3
Into in blast furnace.And covering X1, middle set X2 and small set X3 greatly is undergauge structure from outer to inner, it will not under hot wind impact force action
Into in blast furnace, when disassembly, which provides outside pulling force, be can be taken off.
The utility model embodiment provides a kind of tuyere small sleeve extracting tool, and as shown in Fig. 2, which includes: master
Bar 1, sliding hammer 2, the first locating part 3, the second locating part 4 and the tight part 5 of hook.First locating part 3, sliding hammer 2, the setting of the second locating part 4
On mobile jib 1, and sliding hammer 2 can be slided between the first locating part 3 and the second locating part 4 and on mobile jib 1.Tight part 5 is hooked to connect
It connects in one end of mobile jib 1 and close to the second locating part 4, applies pulling force for the end face clamping with small set X3.
The working principle of tuyere small sleeve extracting tool provided by the embodiment of the utility model is illustrated below:
In use, one end of mobile jib 1 is sequentially passed through in big set X1, middle set X2 and small set X3 insertion blast furnace, make to hook tight part 5
It offsets with the end face of small set X3.Mobile sliding hammer 2 is contacted to the end face of the second locating part 4, to the direction close to the first locating part 3
Quickly sliding hammer 2 is pulled to accelerate sliding hammer 2.Sliding hammer 2 hits the end face of the first locating part 3, and kinetic energy is converted to be limited to first
The impact force of part 3, the impact force apply outside pulling force to small set X3 by mobile jib 1, the tight part 5 of hook.Repeatedly, until small set
X3 and middle set X2 is detached from, and is then pulled out small set X3 by tuyere small sleeve X3 extracting tool.The tuyere small sleeve extracting tool
Working principle diagram may refer to attached drawing 3.
As it can be seen that tuyere small sleeve extracting tool provided by the embodiment of the utility model, hooks tight part 5 by the connection of mobile jib 1, is convenient for
Apply pulling force in the export-oriented small set X3 of blast furnace, opereating specification is larger, convenient for operation.By the sliding motion of sliding hammer 2, by sliding hammer 2
Kinetic energy is converted to the impact force to the first locating part 3, and then applies active force to small set X3, and staff's force is smaller can be right
Small set X3 generates biggish active force, reduces labour's consumption.And structure is simple, use cost is lower, highly reliable.
Wherein, the size etc. of exerting a force when the distance and pulling of the weight of sliding hammer 2, the first locating part 3 and the second locating part 4 because
Element codetermines impact force when sliding hammer 2 hits the first locating part 3, and those skilled in the art can be when in use according to using need
It asks and adjusts above-mentioned parameter voluntarily to achieve the purpose that the small set X3 of disassembly, this is repeated no more in the utility model embodiment.
Optionally, as shown in Fig. 2, which further includes pulling and supporting part 6, pulls and supports part 6 and sliding hammer 2 connects
It connects, for driving sliding hammer 2 to slide.Part 6 is pulled and supported by setting, and staff is hand-held, which to pull and support part 6, more can easily drive cunning
Hammer 2 slides on mobile jib 1.
Wherein, pulling and supporting part 6 can be multiple types, for example, pulling and supporting part 6 can be the handle connecting with sliding hammer 2.Or
Person, pulling and supporting part 6 can also be drawstring or chain etc..
In the utility model embodiment, one end that tight part 5 is connected to mobile jib 1 is hooked, offsets to apply with the end face of small set X3 and draw
Power, as an example, hooking tight part 5 can be rectangular block shape structure, and the maximum plane of rectangular block area is vertical with mobile jib 1, and
It offsets with the end face of small set X3.
The maximum plane of rectangular block area is vertical with mobile jib 1 and offsets with the end face of small set X3, makes to hook tight part 5 and small set X3
Contact area it is larger, convenient for applying pulling force, avoid falling off in disassembly process, improve safety in utilization and reliability.
As another example, the triangular prism structure that tight part 5 can be right angled triangle for section, triangular prism structure face are hooked
The maximum right-angle surface of product is vertical with mobile jib 1, and offsets with the end face of small set X3.Under the premise of not influencing using effect, reduce
The volume of tight part 5 is hooked, material requested is reduced, save the cost.
Optionally, hook tight part 5 can also be section be trapezoidal or other shapes of prism, terrace with edge or rotary table etc. knot
Structure, as long as offer disassembly pulling force can be offseted with the end face of small set X3.
Sliding hammer 2 slides on mobile jib 1, and in order to reduce frictional resistance, pulley can be set between sliding hammer 2 and mobile jib 1.It is logical
Setting pulley is crossed, sliding friction is converted into rolling friction, frictional resistance is reduced, is not only convenient for staff and pulls and supports 2 band of sliding hammer
Dynamic sliding hammer 2 slides on mobile jib 1, and energy loss when energy in 2 moving process of sliding hammer is smaller, when being moved to the first locating part 3
Kinetic energy it is larger, generate biggish impact force.
Optionally, axially disposed on mobile jib 1 to have sliding slot, pulley is limited in sliding slot.So set, making sliding hammer 2 and master
Spacing between bar 1 is smaller, and each component connection is closer, and preferable limit effect can be played to pulley, avoids pulley
Deflection.
Optionally, as shown in attached drawing 2 and attached drawing 3, the first locating part 3 and the second locating part 4 include linking together
The end face of column section and reducer, column section is opposite with the end face of sliding hammer 2.So set, the end face phase of sliding hammer 2 and column section
Right, contact area is larger, avoids colliding with or generating biggish strain.Reducer is connect with column section, make the first locating part 3,
Second locating part 4 and 1 junction of mobile jib are more gentle.
