FIG. 1 is a schematic view of a construction process for installing a temporary fixing of a coke oven column according to the present invention;
FIG. 2 is an enlarged view of a portion A of FIG. 1;
labeled as: the coal charging car comprises a coal charging car track support 1, a furnace column 2, a lifting lug 3, a steel wire 4 and a coke oven top 5.
Detailed Description
The invention is further described with reference to the following figures and detailed description.
It should be noted that, if there are directional indication terms, such as the terms of direction and orientation, above, below, left, right, front and back, in the present invention, for facilitating the description of the relative positional relationship between the components, the absolute position that is not the positional relationship between the related components and the components is specifically referred to, and is only used for explaining the relative positional relationship and the motion situation between the components in a specific posture, and if the specific posture is changed, the directional indication is changed accordingly. When the present invention relates to a number, such as "a plurality", "several", etc., two or more than two are specifically referred to.
As shown in figures 1 and 2, the construction method for temporarily fixing the installation of the oven column of the coke oven comprises the following steps:
A. after the coal charging car track support 1 on the top 5 of the coke oven is installed, a lifting lug 3 is arranged at a position, close to an installation station of the oven post 2, on the coal charging car track support 1;
B. after the installation, leveling and acceptance of the furnace column lower base plate are finished, the furnace column 2 is transported to the front of the furnace by adopting a temporary pushing trolley according to the requirements of numbers and arrangement drawings, and then is hoisted by adopting a traveling crane to be placed on the furnace column lower base plate and is close to the corresponding protection plate;
C. the lower part of the furnace column 2 is fixed by a footing bolt, is provided with a nut and is not screwed up temporarily;
D. then, one end of a steel wire 4 is used for tying the furnace column 2 to the column, the other end of the steel wire 4 is tied to the lifting lug 3 arranged in the step A, and the temporary fixation of the furnace column 2 is realized by utilizing the coal charging car track bracket 1 and the steel wire 4;
E. and carrying out subsequent installation construction, and removing the steel wire 4 and the lifting lug 3 after the furnace column 2 is completely and fixedly installed.
In the step A, the installation and construction of the coal charging car track support 1 can be the same as the original construction mode, the lifting lugs 3 are only pre-installed at proper positions after the installation and construction of the coal charging car track support 1 are completed, if the lifting lugs 3 can be welded and fixed on the coal charging car track support 1 in a welding mode, the lifting lugs 3 are used as a structure for connecting the subsequent steel supply wires 4 and are used as temporary fixing points for the furnace columns 2.
In addition, the step B and the step C are the same as the original hoisting construction mode of the furnace column 2; in addition, before the furnace column 2 is hoisted in the same row, at least five corresponding protection plates of the coke oven need to be installed, so that mutual interference between corresponding protection plates and the hoisting construction of the furnace column 2 can be avoided. Of course, without loss of generality, construction of other necessary structures needs to be completed before the furnace column 2 is hoisted, for example, installation construction and leveling of the furnace column lower backing plate mentioned in the step B, and a corresponding protection plate for closing and matching the furnace column 2 after hoisting; this part of the protective plate is preferably mounted before lifting the furnace column 2, since it fits closely to the furnace column 2. In addition, after the furnace column 2 is hoisted, the lower anchor bolts are adopted for preliminary positioning in the step C, but are not screwed and locked, so that the subsequent fine adjustment operation on the furnace column 2 can be conveniently carried out.
Then, in the present invention, the upper end of the furnace column 2 is connected to the corresponding lifting lug by the steel wire 4 in step D. Through the tractive of steel wire 4 like this, simultaneously with the help of the preliminary location of bolt under the lower margin to stove column 2 lower extreme to and with the help of the dependent action of corresponding protection shield to stove column 2, play the temporary fixation to stove column 2 jointly. Certainly, without loss of generality, the furnace column 2 cannot be completely fixed by the relying action of the steel wire 4, the incompletely screwed and fixed lower foot bolt and the protective plate, but the furnace column 2 is allowed to have a certain movable adjustment amount so as to allow the furnace column 2 to be subjected to subsequent fine adjustment operation; it follows that the temporary fixing of the column 2 in the present invention does not necessarily require the complete fixing of the column 2.
More specifically, in order to ensure the drawing stability of the steel wire 4 to the furnace column 2, the steel wire 4 is preferably arranged to be drawn for 2-3 circles between the furnace column 2 and the lifting lug 3; namely, the steel wire 4 is wound back and forth for a plurality of times to perform drawing so as to improve the drawing effect.
More specifically, the invention also relates to the installation of the iron protection parts of the coke oven in the subsequent part after the furnace column 2 is temporarily fixed, such as the conventional parts of the protection plate, the oven door frame, the oven door, the cross braces and the like in the rest part. And each part needs to be uniformly adjusted after being installed, and is integrally fixed after being finally adjusted in place, so that the integral installation construction is completed. After the integral installation construction is completed, the steel wire 4 and the lifting lug 3 can be disassembled to avoid the influence of the structural components on the subsequent production operation of the coke oven 2 and ensure that the structural components used for temporarily fixing the oven column 2 in the invention can not influence the normal production operation of the coke oven 2.
More specifically, in step E, in the subsequent installation, the installation of the cross braces is generally included, so in the present invention, after the installation of the cross braces is completed, the cross braces are bolted to the furnace pillars 2 by using the wire ropes, so as to realize the double fixing function of the furnace pillars 2, and further provide the temporary fixing effect of the furnace pillars 2. Of course, without loss of generality, the steel wire rope used in step E can also be removed after the furnace column 2 is completely fixed and installed.
