Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 schematically illustrates the structure of the preferred embodiment of the present invention, and as shown in the figure, this preferred embodiment comprises tappet 1, link span 3, wheel 6 and operating assembly.
Wherein, the front end of tappet 1 is used for the medium and small cover of sheathed blast-furnace tuyere, and is the long adjustable structure of bar.Specifically, tappet 1 comprises interior bar 11, urceolus 12 and adjustment pin 2.The rear end of interior bar 11 is fixed on link span 3.Urceolus 12 is in straight-tube shape, and the length direction along interior bar 11 is set on interior bar 11 movably.One end of adjustment pin 2 is connected to limit the position interior bar 11 and urceolus 12 with interior bar 11 through urceolus 12, and it is outside so that operation that the other end is positioned at urceolus 12.More specifically, one end of adjustment pin 2 can be inserted in interior bar 11, or conflicts on the surface of interior bar 11 tightly; The other end of adjustment pin 2 can set up handle, or arranges the structure that other are convenient to tool control, the such as structure such as hole, groove.During application, the extrusion of tappet 1 can be regulated by regulating and controlling pin 2, switch between cover and little cover in replacing to facilitate.The design of adjustable tappet can when changing tuyere medium sleeve or little cover, according to the length changing medium and small cover, synthesise various factor, the complexity of installing medium and small cover as tappet 1, the tuyere zone domain space size, scope of activity etc. that need change medium and small cover determine the length that tappet 1 is flexible.
Link span 3 is case body structure, and the rear end of the interior bar 11 of tappet 1 is fixed on link span 3.Specifically, link span 3 comprises top board (unmarked in figure), axletree 4, back up pad 5.Cover top surface is fixed in the rear end of interior bar 11, back up pad 5 be positioned at top board below and be connected with axletree 4, to increase the structure of link span 3.The bottom of the axletree 4 of link span 3 is located at by wheel 6, so that link span 3 moves forward and backward.
Operating assembly is located at the rear portion of link span 3, for operating the movable of link span 3.Specifically, operating assembly comprises car beam 9, handrail 90, diagonal bar 8.Car beam 9 comprises two rod-like element, and the rear portion of link span 3 is fixed in the front end of rod-like element.Handrail 90 is fixed on the rear end of two rod-like element, is convenient to manual operation.Diagonal bar 8 is in shaft-like, and end is connected between handrail 90 and link span 3, for strengthening structural strength.
For the ease of regulating the pendulum angle of tappet 1, wheel 6 is single wheel.Single wheel design scheme, had both balanced left and right weight, was conducive to again regulating tappet clean and jerk angle, facilitated the contraposition of medium and small cover, installation.
In order to keep the balance of this preferred embodiment under different states, this preferred embodiment also comprises counter-balanced carriage 7 and leg 80.Car beam 9 is arranged the counter-balanced carriage 7 for laying balancing weight, to keep the balance of tappet 1 link span 3 before and after sheathed medium and small cover.Adopt counter-balanced carriage design when changing tuyere medium sleeve or little cover, the weight according to changing medium and small cover can be followed, on counter-balanced carriage 7 with addition of balancing weight to balance the front and back weight of link span 3.The upper end of leg 80 is connected to the downside of diagonal bar 8.Preferably, the position of counter-balanced carriage 7 between leg 80 and link span 3.For balancing weight, also can be replaced by the object that steel scrap isodensity is larger.In other embodiments, the upper end of leg 80 also can be connected to diagonal bar 8 and car beam 9 simultaneously.
One of using method of this preferred embodiment is as follows:
After blast furnace staying, blast-furnace man receives instruction, unload blowpipe rapidly, then cover or little cover in using medium and small cover towing hook to drag, before this preferred embodiment is pushed into air port, adjust the length of tappet 1, cover or little cover is made to be enclosed within tappet 1, with addition of the balancing weight (or bloom etc.) of suitable weight on counter-balanced carriage 7, balance the front and back weight of link span 3, operate handrail 90 afterwards to pull back this preferred embodiment and deposit to appropriate location temporarily, change operation be advisable not hinder, guard against medium and small cover in drawing process and come off.
In installation when cover or little cover, according to air port near zone size and medium and small cover size, adjust the collapsing length of tappet 1, and the medium and small cover cover that need install to the front end of tappet 1, with addition of the counterweight code (or bloom etc.) of suitable weight on counter-balanced carriage 7, weight before and after balance is good, promote this preferred embodiment to front, air port, adjust the angle in tappet 1 and air port, accurate with air port contraposition, then middle cover or little cover are pushed in air port, finally exit this preferred embodiment.
Certain blast furnace repeatedly damping down is changed medium and small cover practice and is shown, carry out medium and small cover by using this preferred embodiment and change operation, removing and installing of medium and small cover can be effectively realized in the region, air port that platform is narrow and small, reduce the labour intensity of workman and the generation of security incident, decrease the time that damping down changes medium and small cover, enhance productivity.
In sum, the present invention has the following advantages:
Structure is simple, and manufacturing cost is extremely low.Structure is simple, low cost of manufacture, only simple weldprocedure need be used to make.
Tappet is flexibly flexible, and counterweight balance is good.By regulating adjustment pin to control tappet collapsing length flexibly, when changing medium and small cover, the contraposition accuracy of medium and small cover can be ensured; Afterbody adopts counter-balanced carriage design, and wheel adopts single design, and all around balance is better.
Safe and reliable, reduce potential safety hazard.Operation is simple but also safety not only, workman only need operate handrail and coordinate tuyere platform cucurbit to hang, the a small amount of workman of extra need coordinates to complete medium and small cover replacing operation, greatly reduces the chance that workman directly contacts the medium and small cover of high temperature, reduce injure by a crashing object, the generation of scald accident.
Effectively be applicable to the blast-furnace tuyere region operation that platform is narrow and small.In the tuyere platform operation that platform is narrow and small, zone of action size near air port can be changed according to blast furnace, suitably shorten tappet length, to reduce operating radius and equipment occupation space, greatly reduce the generation of security incident.
Volume is little, does not limit storage place.Tuyere platform corner can be left at ordinary times or spare part is deposited a little, take up room less, before treating the operation of programmed replacement air port, be transported to designated area.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
