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 refers to a lance holder with a protector for curved lances, in particular curved oxygen lances. Besides a clamping head 5 with a fixing member 6 and a clamping 7, the lance holder 1 used for an effuse 2, in particular for an oxygen lance is also provided with a prefixing member 15 responsible for fixing in advance the effuse 2 to be guided to the lance holder 1 such that when curved, the effuse 2 can not slide and in particular can not rotate in a center clamping member 31. In addition, the lance holder 1 has an output valve 53 and a non-return valve 11 of special types, and a column springs 10 or a non-return spring is arranged in a sealed member so as to avoid influence by gas. In addition, a necessary burn-back protective device 9 is taken out of a movement path of the effuse 2 to be inserted so as to be profitably arranged by protected areas.

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 ...
