Fixed automatic ignition device
Technical field
The utility model relates to a kind of fixed automatic ignition device, relates in particular to a kind of device of automatically oxygen lance being lighted a fire.
Background technology
In the prior art, fixed automatic ignition device comprises that front end has the burning torch of nozzle, elevating mechanism and oxygen lance.Wherein, burning torch and oxygen lance all are fixed on the elevating mechanism, burning torch and oxygen lance are along with elevating mechanism is the same together down thus, thereby when causing oxygen lance near the surface of steel plate cutting steel plate, the nozzle of burning torch is also very near from the distance of steel plate, thus, the splash that the nozzle of burning torch is easy to be cut down by steel plate stops up, and causes whole apparatus function impaired.
The utility model content
The purpose of this utility model is to make that the nozzle in the fixed automatic ignition device is not easy blocked.
In order to reach this purpose, the fixed automatic ignition device that the utility model provides comprises: front end has burning torch, the elevating mechanism of nozzle and is fixed on oxygen lance on the described elevating mechanism, wherein, described burning torch is arranged on the burning torch fixture, and described oxygen lance can be lighted by described burning torch when certain position.
In above-mentioned igniter, described burning torch fixture comprises installing plate and fixed bar, and described burning torch is fixed on the described installing plate by described fixed bar.
In above-mentioned igniter, the junction of described fixed bar and described installing plate is provided with adjusting device, and the angle between described fixed bar and described installing plate is adjusted by described adjusting device.
In above-mentioned igniter, described adjusting device is a screw.
In above-mentioned igniter, the junction of described fixed bar and described burning torch is provided with rotatable, and the angle between described fixed bar and described burning torch is adjusted by rotatable.
The utility model adopts rod member to connect, and can reach the fine effect that gets the time simple in structure, and the nozzle of burning torch and the distance that is cut steel plate are strengthened, thereby has reduced the possibility of cutting splash obstruction nozzle.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See also Fig. 1, Fig. 1 is a structural representation of the present utility model.As shown in the figure, the utility model comprises that front end has the burning torch 1 of nozzle 4, elevating mechanism 8 and oxygen lance 3.Wherein, burning torch 1 is installed on the fixed bar 6 through rotatable 5, and fixed bar 6 is fixed on the installing plate 7.Oxygen lance 3 is installed on the elevating mechanism 8 through support 2.Junction 7 of fixed bar 6 and installing plates is provided with set screw 9, thereby angle between the two can be adjusted by set screw 9; Equally, be provided with rotatable 5 in the junction of fixed bar 6 and burning torch 1, angle is between the two adjusted by rotatable 5, and above-mentioned adjustment has guaranteed that the nozzle 4 of burning torch 1 can light oxygen lance 3 in a certain position.
The course of action of this device is: at first igniting.Oxygen lance 3 is raised to peak (being A position among Fig. 1) with elevating mechanism 8; This moment, the horizontal range of nozzle 4 relative oxygen lance 3 bottom centre positions was 110mm, and vertical range is 60mm, and burning torch 1 is lighted oxygen lance 3 by nozzle 4.Cutting then.The oxygen lance of being lighted 3 is reduced to distance with elevating mechanism 8 and is cut the steel plate suitable distance; Oxygen lance 3 begins being cut the steel plate cutting.In the whole process, burning torch 1 absolute position is constant, so nozzle 4 can be very not near from steel plate, thereby has reduced the possibility of the splash obstruction nozzle 4 on the steel plate.
In the above-described embodiments, burning torch is installed on the burning torch fixture, and the burning torch fixture comprises installing plate 7 and fixed bar 6.Should be understood that the burning torch fixture is not limited thereto, thereby burning torch 1 is not as long as be installed in elevating mechanism 8 not along with elevating mechanism 8 motions.In addition, spill spin block 5, set screw 9 and fixed bar 6 are not necessary conditions, and those of ordinary skills can adjust according to the needs of oneself.
The foregoing description is only given an example for convenience of description, is not the restriction to scope of the present utility model.For the general personnel in present technique field, can under the situation that does not break away from spirit of the present utility model, make many variations.Therefore, the scope advocated of the utility model should be as the criterion so that the claim in claims is described.
