Coke oven lower jet pipe installation auxiliary device
The utility model relates to a kind of coke oven construction instrument, particularly a kind of coke oven lower jet pipe installation auxiliary device.
The coke oven lower jet pipe is used for collecting coal gas, it is just as the blood vessel of coke oven, be clouded on the base roof plate that is formed by concrete placement, irreplaceable status is arranged, usually, just be thick with number on the single seat coke oven base roof plate in several thousand lower jet pipe, and standard is to lower jet pipe absolute altitude, verticality, have a strict requirement in length and breadth to the position.Therefore, the installation of jet pipe is one of emphasis in the coke oven construction process under the coke oven base roof plate, take the 6 meters carbonizing chamber coke ovens in 55 holes as example, each combustion chamber gas pipe of coke oven is comprised of 32 lower jet pipes, single seat coke oven lower jet pipe quantity has just reached 1760, and the upper and lower ends of the mouth of pipe is connected with the pipe brick of coke furnace building and canopy pipe and the vertical tube of vault respectively, and is very high to the accuracy requirement of installing, installation quantity is large, brings very large difficulty to installation process.As lower jet pipe can not well be installed, can't guarantee the quality of coke oven.
Therefore, adopt coke oven lower jet pipe installation auxiliary device, can smoothly lower jet pipe be fixed by design requirements, and be convenient to before concrete placement, adjust, greatly reduced the difficulty of construction at this position, and than conventional construction method economical with materials.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model provides, and convenient operation can assist horizontal coke oven lower jet pipe that the supplementary unit of finishing smoothly is installed.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of coke oven lower jet pipe installation auxiliary device, comprise fixed frame, lower fixed frame, horizontal base, be connected and fixed bar and fixed frame support, described upper fixed frame upper surface is welded with the fixed frame support, upper fixed frame is connected with lower fixed frame by being connected and fixed bar, lower fixed frame bottom surface is welded with horizontal base, upper fixed frame is a plurality of trepanning I of distribution evenly, and lower fixed frame is a plurality of trepanning II of distribution evenly.
The center of described trepanning I and trepanning II on an axis.
Compared with prior art, the beneficial effects of the utility model are:
A kind of coke oven lower jet pipe installation auxiliary device, have simple in structure, easy to use, time saving and energy saving, recycling, characteristics that setting accuracy is high, be convenient to simultaneously the integrated operation of lower jet pipe, can assist the installation of coke oven lower jet pipe to finish smoothly, effectively raise working efficiency, reduced the waste of resource.

Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
As shown in Figure 1, a kind of coke oven lower jet pipe of the utility model installation auxiliary device, comprise fixed frame 1, lower fixed frame 2, horizontal base 3, be connected and fixed bar 4 and fixed frame support 5, upper fixed frame 1 upper surface is welded with fixed frame support 5, upper fixed frame 1 is connected with lower fixed frame 2 by being connected and fixed bar 4, lower fixed frame 2 bottom surfaces are welded with horizontal base 3, upper fixed frame 1 is a plurality of trepanning I 6 of distribution evenly, lower fixed frame 2 is a plurality of trepanning II 7 of distribution evenly, the center of trepanning I 6 and trepanning II 7 on an axis, the aperture of trepanning I 6 and trepanning II 7 and spacing are installed as required aperture and the spacing of lower jet pipe 8 and are processed.
As shown in Figures 2 and 3, when using the utility model, at first lower jet pipe 8 one ends are passed trepanning I 6 and trepanning II 7 successively, until this end arrives to lower fixed frame 2 bottoms, then angle steel 9 dual-sides are close to upper fixed frame 1 and lower jet pipe 8 respectively, after fixing with jig, again lower jet pipe 8 is welded into integral body with angle steel 9, unclamp afterwards jig, lower jet pipe 8 is lifted out with angle steel 9 integral body, namely finish a whole unit assembling of time jet pipe 8, and then can accurately finish smoothly the pre-buried installation of the lower jet pipe 8 of coke roof.
Above described only be ultimate principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
