Background technology
Bull gear is one of rotary kiln critical piece, and in the rotary kiln installation process, the installation of bull gear is an important step, its required precision height, complex process.At present, the bull gear method is installed mainly contains two kinds, the one, parts are installed: be with cylinder of rotary kiln install centering good after, again two half-ring gears are distinguished installation centering in place, its advantage is to install after cylindrical shell is linked to be integral body, and shortcoming is to be difficult to guarantee its circularity and installation accuracy; The 2nd, integral installation: in advance the two half rings group to becoming whole, whole circle installation centering in place.Its advantage is to guarantee gear ring circularity, and shortcoming is to be linked to be at cylindrical shell must be enclosed within advance on the shell ring before whole, setting face arrange fixing.
More than two kinds the bull gear methods are installed all will be after the cylindrical shell butt joint connects, by large-tonnage elevator assembly pulley is set, dish rotary kiln body is measured centering to all (replacing) cylindrical shell central straight dimensions, coil again the rotary kiln body to bull gear axially and radial beat centering repeatedly, wherein many instruments and measure to be set.Last fixing spring plate and cylindrical shell become integral body (riveted joint or welding).Only bull gear is installed or is changed subitem and needs 6 days durations at least, and because dish rotary kiln running body instability adds the kiln axon to play, bull gear centering precision is difficult to guarantee.Consume a large amount of manpower and materials simultaneously.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and providing a kind of can effectively shorten the rotary kiln installation and maintenance duration, improves the installation method of the big gear ring of rotary kiln of installation accuracy.
The objective of the invention is to be achieved through the following technical solutions.
A kind of installation method of big gear ring of rotary kiln, it is characterized in that its installation process be in advance with bull gear and its down shell ring assembling, centering, be connected to an integral body after, carry out integral installation again.
The installation method of a kind of big gear ring of rotary kiln of the present invention, it is characterized in that described with bull gear and its down shell ring assembling, centering, be connected to holistic process bull gear carried out with its time vertical placing on the assembly platform of shell ring.
The installation method of a kind of big gear ring of rotary kiln of the present invention, it is characterized in that being provided with between two parties on the described assembly platform newel, being provided with one on newel can be around the horizon bar of newel rotation, at the scriber that is provided with setting-out on the bull gear pitch circle on the horizon bar, be used for the radially dial gauge device of centering, centralized positioning of bull gear.
Adopt method of the present invention, in advance with bull gear and its down shell ring assembling, centering, be connected to an integral body after, carry out integral installation again, large-tonnage lifting dish rotary kiln body mechanism need be set, directly on assembly platform, carry out cylindrical shell and gear ring beat centering.Can effectively shorten the rotary kiln site operation duration, improve the bull gear installation accuracy.
Description of drawings
The structural representation of the assembly platform that Fig. 1 uses for the method for the present invention institute right to use.
Fig. 2 is the vertical view of Fig. 1.
1 is scriber among the figure, and setting-out on the bull gear pitch circle is used for radially centering (centralized positioning) of bull gear; 2 is the dial gauge device, is used for radially centering (centralized positioning) of shell ring; 3 for horizontal column is that rotating shaft is faced and arranged column, top that bearing is housed, and horizontal centering cross bar is that central pivot point is rotated with it; The 4th, shell ring; The 5th, bull gear; The 6th, latch plate; The 7th, support bull gear and face and arrange (having jack, removable and fixing bull gear); The 8th, assembly platform.
The specific embodiment
A kind of installation method of big gear ring of rotary kiln, its installation process be in advance with bull gear and its down shell ring assembling, centering, be connected to an integral body after, carry out integral installation again; With bull gear and its down shell ring assembling, centering, be connected to holistic process bull gear carried out on the assembly platform with its time vertical placing of shell ring; Be provided with a newel on the described assembly platform between two parties, being provided with one on newel can at the scriber that is provided with setting-out on the bull gear pitch circle on the horizon bar, be used for the radially dial gauge device of centering, centralized positioning of bull gear around the horizon bar of newel rotation.
The concrete operations step is as follows:
1. make bull gear centering assembly platform.
2. bull gear and following shell ring thereof are detected the school circle respectively.
3. centering rotating shaft and instrument are set.Be ready to Work tools such as spirit level and jack.
4. bull gear and shell ring level are reached radially levelling capturing.
5. mounting spring plate, fixing spring plate and shell ring are an integral body.
6. adopt large-tonnage lifting equipment to carry out integral hoisting.
7. adopt the assisted deceleration machine to drive big pinion mate cylindrical shell and carry out smart centering.
8. set up measuring table, measure bull gear and axially reach the circular runout value, the centering by shell ring both sides docking port under it makes bull gear axially reach the circular runout value and meets installation specification.
9. welding shell ring both sides circumferential weld is finished the bull gear mounting process.
Method of the present invention is placed on bull gear assembling that overhaul (installations) is preceding to be carried out, and maximum 2 days of on-the-spot installation can shift to an earlier date 4 days durations.And the precision height, improve workmen's operating environment simultaneously and reduce labor intensity, it is considerable to create economic benefit.
Embodiment
Two half-turn structures of the many employings of big gear ring of rotary kiln link together with the counterpart screw, tangentially are fixed on the kiln body by latch plate; Concrete implementation step is as follows:
