Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 schematically shows the structure of the utility model preferred embodiment, 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.Particularly, bar 11, urceolus 12 and adjusting pin 2 in tappet 1 comprises.The rear end of interior bar 11 is fixed on the link span 3.12 of urceolus are straight-tube shape, in being set in movably along the length direction of interior bar 11 on the bar 11.An end of regulating pin 2 pass urceolus 12 be connected with interior bar 11 to limit in position between bar 11 and the urceolus 12, it is outside so that operate that the other end is positioned at urceolus 12.More specifically, an end of regulating pin 2 can insert in the interior bar 11, perhaps conflicts tightly on the surface of interior bar 11; Regulate the other end of pin 2 and can set up handle, other perhaps are set are convenient to the structure that instrument is handled, for example structure such as hole, groove.During application, can be by the extrusion of regulating and controlling pin 2 adjusting tappets 1, conveniently in replacing, to switch between cover and the little cover.Can regulate the design of tappet can be in changing the air port when cover or little cover, according to the length of changing medium and small cover, comprehensive each side factor is installed the length that definite tappets 1 such as the complexity of medium and small cover, the tuyere zone domain space size that needs to change medium and small cover, scope of activity stretch as tappet 1.
Link span 3 is casing shape structure, and the rear end of the interior bar 11 of tappet 1 is fixed on the link span 3.Particularly, link span 3 comprises top board (unmarked among the figure), axletree 4, back up pad 5.Cover top surface is fixed in the rear end of interior bar 11, and 5 of back up pads are to be positioned at the below of top board and to be connected with axletree 4, to increase the structure of link span 3.Wheel 6 is located at the bottom of the axletree 4 of link span 3, so that link span 3 moves forward and backward.
Operating assembly is located at the rear portion of link span 3, is used for being operatively connected moving forward and backward of frame 3.Particularly, operating assembly comprise car beam 9, hold up bar 90, diagonal bar 8.Car beam 9 comprises two rod-like element, and the front end of rod-like element is fixed in the rear portion of link span 3.Hold up bar 90 to be fixed in the rear end of two rod-like element, be convenient to manual operation.Diagonal bar 8 is shaft-like, and the end is connected in to be held up between bar 90 and the link span 3, is used for strengthening structural strength.
For the ease of regulating the pendulum angle of tappet 1, wheel 6 is single wheel.Single wheel design scheme, both balance left and right sides weight, be conducive to regulate tappet clean and jerk angle again, contraposition, the installation of convenient medium and small cover.
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.Be provided for laying the counter-balanced carriage 7 of balancing weight on the car beam 9, to keep the balance of tappet 1 link span 3 before and after sheathed medium and small cover.Adopt the counter-balanced carriage design can be in changing the air port when cover or little cover, follow the weight according to the medium and small cover of replacing, on counter-balanced carriage 7 with addition of the front and back weight of balancing weight with balance link span 3.The upper end of leg 80 is connected in 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 bigger object of steel scrap isodensity.In other embodiments, the upper end of leg 80 also can be connected in diagonal bar 8 and car beam 9 simultaneously.
One of using method of this preferred embodiment is as follows:
Behind the blast furnace staying, the blast-furnace man receives instruction, unload blowpipe rapidly, use medium and small cover towing hook to drag middle cover or little cover then, before this preferred embodiment is pushed into the air port, adjust the length of tappet 1, cover or little cover are enclosed within on the tappet 1, on counter-balanced carriage 7 with addition of the balancing weight of suitable weight (or bloom etc.), the front and back weight of the good link span 3 of balance, operation is afterwards held up bar 90 to pull back this preferred embodiment to appropriate location and is deposited temporarily, is advisable not hinder the replacing operation, guards against medium and small cover in the drawing process and comes off.
Cover or during little cover in the installation, 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 condom that need are installed is to the front end of tappet 1, on counter-balanced carriage 7 with addition of the counterweight sign indicating number of suitable weight (or bloom etc.), weight before and after balance is good, promote this preferred embodiment to the place ahead, air port, adjust the angle in tappet 1 and air port, accurate with the air port contraposition, then middle cover or little cover are pushed in the air port, withdraw from this preferred embodiment at last.
Certain blast furnace repeatedly damping down is changed the practice of medium and small cover and is shown, change operation by using this preferred embodiment to carry out medium and small cover, can effectively realize removing and installing of medium and small cover in the narrow and small zone, air port of platform, reduce the generation of working strength of workers and security incident, reduced damping down and changed the time of medium and small cover, enhanced productivity.
In sum, the utlity model has following advantage:
Simple in structure, manufacturing cost is extremely low.Simple in structure, low cost of manufacture only needs to use simple weldprocedure to make.
Tappet is flexibly flexible, and counterweight balance is good.Can be by regulate regulating pin control tappet collapsing length flexibly, when changing medium and small cover, can guarantee the contraposition accuracy of medium and small cover; Afterbody adopts the counter-balanced carriage design, and wheel adopts single design, and all around balance is better.
Safe and reliable, reduce potential safety hazard.Operation not only simply but also safety, the workman only need operate and hold up bar to cooperate the tuyere platform cucurbit to hang, additionally need a small amount of workman to coordinate to finish medium and small cover and change operation, significantly reduced the chance that the workman directly contacts the medium and small cover of high temperature, reduced injure by a crashing object, the generation of scald accident.
Effectively be applicable to the blast-furnace tuyere zone operation that platform is narrow and small.In the narrow and small tuyere platform operation of platform, can change near the air port zone of action size according to blast furnace, suitably shorten tappet length, to reduce operating radius and equipment occupation space, reduce the generation of security incident greatly.
Volume is little, does not limit storage place.Can leave tuyere platform corner or spare part at ordinary times in and deposit a little, it is less to take up room, and treats that being transported to the designated area before the operation of programmed replacement air port gets final product.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
