Background technology
Blast funnace hot blast stove furnace bottom equipment is one of visual plant of iron-smelter, and it is 115 tons parts that general every blast funnace hot blast stove furnace bottom equipment always has 1387 total weightes, and wherein maximum package weight is 4.5 tons, and these parts all are dependent on the radius loop wheel machine and are in place.Existing radius loop wheel machine mainly is made up of parts such as platform crossbeam, vertical suspension rod, gyro-rotor, straight line bull headction, second hoist ceiling crane, second set of wheels, annular bull headction, first set of wheels, first hoist ceiling cranes; Link to each other through the piece that is rigidly connected between first set of wheels and the straight line bull headction, the card rail or the phenomenon that slides down often occur.
In addition; According to designing requirement; The radius loop wheel machine must be able to be done 360 ° of rotations, because the intrinsic annular bull headction of radius loop wheel machine receives the restriction of condition when making, its out of roundness tolerance has surpassed the technical requirements of original design ± 2mm widely; The situation that causes first set of wheels to be stuck on the annular bull headction is very serious; First set of wheels was difficult to along annular bull headction operation after the radius loop wheel machine was installed, unique adjustable be the wheel and the gap between the annular bull headction that strengthens first set of wheels, still do major accidents such as the wheel that first set of wheels very likely occurs slides down, spare part falls like this.And simultaneously, existing lifting equipment all can not directly enter and carry out lifting operation in the stove.
Summary of the invention
The purpose of the utility model be exactly to provide a kind of simple in structure, safe and reliable, hanging device does not block the radius loop wheel machine that rail does not slide down smoothly.
For realizing above-mentioned purpose; The utility model institute design-calculated is a kind of not to block the radius loop wheel machine that rail does not slide down, and comprises the platform crossbeam, and platform crossbeam bottom is equipped with annular bull headction; On the annular bull headction first set of wheels that matches with its base is installed, first set of wheels links to each other with first hoist ceiling crane; Be positioned at annular bull headction circle centre position on the platform crossbeam and be provided with vertical suspension rod; The lower end of vertical suspension rod is provided with can be around the gyro-rotor of its rotation; Be fixed with the straight line bull headction on the sidewall of gyro-rotor; Second set of wheels that matches with its base is installed on the straight line bull headction; Second set of wheels links to each other with second hoist ceiling crane, and the driven wheel group that matches with its top margin also is installed on the straight line bull headction, links to each other through flexibly connecting frame between the top fixed transverse rod of driven wheel group and the bottom fixed transverse rod of first set of wheels.
As preferred version, the said frame that flexibly connects comprises an orthogonal opening key seat in upper and lower opening orientation, a del connecting panel and an equilateral triangle connecting panel; The upper shed of said opening key seat links to each other with the base angle of del connecting panel through first bearing pin, and two drift angles of said del connecting panel link to each other with the bottom fixed transverse rod of first set of wheels; The under shed of said opening key seat links to each other with the drift angle of equilateral triangle connecting panel through second bearing pin, and two base angles of said equilateral triangle connecting panel link to each other with the top fixed transverse rod of driven wheel group.
Further, said gyro-rotor is installed in the lower end of vertical suspension rod through the thrust shaft block that is arranged on its bottom.
The principle of work of the utility model is such: change into through the piece that will be rigidly connected and flexibly connect frame and driven wheel group; Being connected of first set of wheels and straight line bull headction top become by being rigidly connected to flexibly connect; Thereby the operation that makes first set of wheels do not receive annular bull headction out of roundness tolerance restriction and can free trouble-free operation; Even annular bull headction is that polygonal also it doesn't matter, as long as a chances are circle.
The advantage of the utility model is: do not block rail when first set of wheels of radius loop wheel machine is moved on annular bull headction, do not slide down, simple in structure, safe and reliable, and hanging device smoothly.
