Embodiment Construction

[0035] for in figure 1 In the spray gun holder 1 shown in , a pre-fixing element 15 is shown in front of the actual clamping head 5 . This pre-fixing part 15 is shown in section and transitions into the fixing part 6, which in figure 1 not identifiable in . The prefix 15 is equipped with a swivel 41 associated with the top 40, wherein, figure 2 It is shown that the surface 42 of the swivel 41 is rough in order to be able to reliably handle the component even with thicker gloves. The housing 14 of the spray gun holder 1 has chamfers 62, 62' at various points. A part of the housing 14 is designed as a sliding sleeve 25 and is displaceable via the toggle lever 17 and the handle 18 in or against the oxygen flow direction 16 . For this reason, toggle lever 17 and sliding sleeve 25 are connected via hinge 19 to the fixed part via hinge 21 . The fixed part is the screw ring 44 or the housing part which accommodates the flashback protection not discernible here. The handle 18 i...

Abstract

The invention relates to a lance holder with a protective device for non-straight, in particular curved, oxygen lances, a lance holder 1 provided for a nozzle tube 2, in particular an oxygen lance, in addition to having a fixing part 6 and a clamping part 7 On the outside of the collet 5 there is a pre-fixing element 15, which is responsible for fixing the nozzle pipe 2 to be introduced into the spray gun frame 1 in such a way that when it is a curved nozzle pipe 2, it can no longer Sliding and especially no longer able to turn. Furthermore, the lance holder 1 is constructed with a special type of outlet valve 53 and non-return valve 11 whose cylinder spring 10 or non-return spring 54 is arranged in a closed component so that it is not affected by the gas flowing through. Furthermore, the necessary flashback protection device 9 is taken out of the path of movement of the nozzle 2 to be inserted and is thus advantageously arranged in a protected manner.

Description

technical field [0001] The invention relates to a lance frame (Lanzenhalter) for a lance (Lanzenrohr), in particular an oxygen lance, in particular used in the metallurgical and iron and steel industry, with a clamping head having a fixing part surrounding the lance and Sleeve-shaped clamping part movable thereon; and sleeve sealing ring (Huelsendichtring) which clamps the nozzle tube and can be influenced via the fixing part and thus seals; and burnback protection device (Rueckbrandsicherung); and a check valve loaded via a column spring (Zylinderfeder). Background technique [0002] Such a spray gun holder is known from DE 10 2008 012 554 B4. Such lance racks are used for lances which are generally several meters long and have the advantage that they can be used for entire rows of lance diameters at least at a certain distance. In this known spray gun holder, the holder has a specially configured holder with a pressure element, that is, a component, which should fix the ...
