Description
Technical field
The present invention relates to a kind of installation method of rotary kiln tyre.
Background technology
Rotary kiln is a cylindric thing that constant slope is arranged, and gradient is 3～3.5%, promotes material in rotary kiln, to stir by the rotation of kiln, makes that material mixes mutually, contact is reacted.Kiln hood coal powder injection burning produces a large amount of heat, and heat is passed to material with modes such as the convection current of flame radiation, hot gas, kiln brick (kliner coating) conduction.Material relies on the gradient of kiln cylinder body and rotation motion forward in kiln of kiln.The installation of rotary kiln comprises: cylinder of rotary kiln is installed, drive apparatus is installed, the carrying roller group is installed, the retaining roller is installed, bull gear is installed and the wheel band is installed.Rotary kiln has strong thermal technology's load and quantity-produced working system aborning, and installation quality is required very strictness, the quality of its installation quality, and can be directly connected to full factory production line normally move.
The rotary kiln main part mainly contains drive end stand, Partner stand, drive apparatus, cylindrical shell, carrying roller installation.The wheel band is the stressed of whole cylindrical shell and transmission supporter in whole system, and edge is enclosed within on drive end stand and the cylindrical shell above the Partner stand, is respectively drive end Propelling wheel band, Partner Propelling wheel band.Require drive end Propelling wheel band and Partner Propelling wheel band and band center line and carrying roller central lines.
In the prior art, the installation of rotary kiln is carried out on ground, and the mode through segmental hoisting is installed in the high-altitude then, and there is the big defective of cylindrical shell centerline deviation in this method.
Summary of the invention
The installation method that the purpose of this invention is to provide a kind of rotary kiln tyre, this method are used for rotary kiln to be installed in the high-altitude, adopts the installation method of limit in place, limit centering; Hoisting alignment is once accomplished; High-efficient simple has improved installation progress, has significantly reduced installation cost; And improved installation quality, the cylinder of rotary kiln centerline deviation is reduced greatly.
The present invention realizes through following technical scheme:
The installation method of rotary kiln tyre comprises that basis examination, drive end stand and Partner stand centering, carrying roller group are installed, cylindrical shell is installed centering, the installation of wheel band, it is characterized in that the concrete installation steps of taking turns band are following:
1) falsework builds; Between the two stands that the wheel band is installed in advance, place a falsework, and on outrigger, put crescent moon stand and press well;
2) lifting that wheel is with cylindrical shell is installed in advance; The cylindrical shell that the wheel band will be installed with crane and steel wire rope in advance lifts to two stands, and its middle cylinder body one end and mounted cylindrical shell are to good position;
3) wheel band edge cover; With cylindrical shell jack-up slowly, make cylindrical shell leave outrigger with press, will take turns band and be inserted on the cylindrical shell, with press back pressure slowly, cylindrical shell is dropped on the support then;
4) wheel band position adjustment; After wheel band edge is inserted in cylindrical shell, carries out the position adjustment wheel band center is overlapped with the carrying roller center; Method of adjustment is:
1. below the wheel band, adopt two press to discharge in the lump and put, and between press one and wheel band, place round steel;
2. adopt two press two to cooperate press one adjustment wheel band and cylindrical shell gap again in wheel band both sides again, make the wheel band even with each gap of cylindrical shell;
3. then on the cylindrical shell circumference at interval hexagonal angle evenly hang 3 hand cranes that pressure is identical;
4. first two hand cranes of tension downside, up to draw motionless till; Hand crane returns the hand crane below two more also to drawing motionless position above the tension then, and the wheel band will be to high-end mobile a bit of distance; Repeat said method, the wheel band is slowly moved ahead,, in wheel band both sides position block is set at last and makes the wheel band keep stable up to wheel band center line and carrying roller central lines;
5) the outrigger height adjustment that wheel is with is installed; Adjustment outrigger height makes the wheel band become line to contact with two carrying rollers.
Compared with prior art, advantage of the present invention is:
This method is used for rotary kiln installs in the high-altitude, adopts the installation method of limit in place, limit centering, and hoisting alignment is once accomplished; High-efficient simple has improved installation progress, has significantly reduced installation cost; And improved installation quality, the cylinder of rotary kiln centerline deviation is reduced greatly.
