Background technology
At steel plant's most of walking beam furnace furnace bottom machinery is to adopt liftings, translation clad steel structural framing, inclined rail seat, double base roller type structure up and down, and the motion through built-in beam and step rate makes steel billet mobile in stove.Promoting with translational frame needs some groups of centering wheels carry out the centering pilot effect to it in moving process, prevents to promote and translational frame squints when moving, and promptly avoids the steel billet on the moving beam that translational frame supports in the stepping process, to squint.
Traditional centering wheel apparatus is on the centering wheeling support, to open elongated hole, realizes the adjusting to gap between centering wheel and the guide pass through regulating the centering wheeling support during installation.The centering wheel is installed and is adjusted back (reserving certain clearance between centering wheel and the centering guide rail), around the centering wheeling support, adds solid welding and decides block.Furnace bottom machinery causes the variation in centering wheel and the gap between the guide rail of feeling relieved owing to the variation of some reasons such as environment temperature etc. in running.When between needs adjustment centering wheel and the centering guide rail during gap, because the centering wheeling support is regulated the difficulty trouble, so each steel mill not takes turns the gap to centering and adjusts in actual moving process.If so excesssive gap, the phenomenon of blank sideslip can appear in centering pilot deleterious then; If the gap is too small, then mobile framework is felt relieved takes turns the effect of pressure, moves the force-bearing situation variation of framework, produces internal stress, and running resistance also will increase simultaneously.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existence; A kind of adjustment that realizes gap between centering wheel and the centering guide rail is provided, the adjustable centering wheel apparatus of machinery at the bottom of the walking beam furnace that can also adjust the perpendicularity of centering wheel shaft simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
The adjustable centering wheel apparatus of machinery at the bottom of the walking beam furnace; Include centering wheeling support and the interior centering wheels of race that are installed in the centering wheeling support; It is characterized in that: described centering wheels comprise the centering wheel and pass the centering wheel shaft of centering wheel; Self-aligning roller bearing and centering axle sleeve are installed between centering wheel shaft and the centering wheel, and at the axle sleeve end face bearing gland are installed, the race both sides of described centering wheeling support are provided with the microscler axis hole that supplies the centering wheel shaft to pass; The centering wheel shaft can drive the centering wheel along the translation on the vertical axial direction of microscler axis hole; The described centering wheeling support outside also is symmetrically installed with the adjusting screw mandrel of pair of parallel, regulates the two ends that screw mandrel connects the wheel shaft of feeling relieved respectively, regulates the translation distance of centering wheel shaft in microscler axis hole.
In such scheme, the two ends of described centering wheel shaft are respectively arranged with axis hole, and the adjusting screw mandrel passes axis hole and is connected with the centering wheel shaft, and the end of regulating screw mandrel is provided with step and blocks axis hole, and will regulate screw mandrel through nut and fix with the centering wheel shaft.
In such scheme, described race is the cavity that is located at the inner openings at one side of centering wheeling support, and the size of race is greater than the diameter of centering wheel.
In such scheme, the cylindrical of described centering wheel protrudes in outside the race, and its outstanding distance is greater than the maximum diameter of hole of microscler axis hole.
In such scheme, all wheel shaft is vertical is provided with centering for described adjusting screw mandrel.
In such scheme, described adjusting screw mandrel is installed in through being threaded on the centering wheeling support, and is regulating the length that adjusting nut adjusting leading screw is installed on the screw mandrel.
Operation principle of the present invention is that centering wheel and self-aligning roller bearing, centering axle sleeve, bearing gland etc. are assembled into the centering wheels, is installed in the microscler axis hole of the wheeling support of feeling relieved through the centering wheel shaft wheels of will feel relieved.Each installs an adjusting screw mandrel respectively in the two line screws up and down of centering wheeling support, regulates screw mandrel and through the axis hole at two ends about the wheel shaft of feeling relieved the centering wheel shaft is fixed, thereby realize fixing the centering wheels.Through adjustment to two adjusting screw mandrels, the wheels of feeling relieved are moved forward and backward, promptly realized adjustment to the gap between centering wheel and the centering guide rail, the while can also be regulated the perpendicularity of centering wheel axis through the length of asynchronous adjusting two adjusting screw mandrels.
Beneficial effect of the present invention is:
This centering wheel apparatus install adjustment fixing after, can adjust with the perpendicularity of centering wheel shaft centering wheel and the gap between the centering guide rail efficiently and easily, guarantee to feel relieved with this and take turns the perpendicularity of cylindrical.
Can guarantee to feel relieved through reasonable adjustment contacts well between wheel and the centering guide pass, prolongs service life of the centering wheel and the guide rail of feeling relieved; Immediately rationally to the adjustment in gap between centering wheel and the guide rail, guarantee centering pilot effect, prevent blank sideslip in the stove lifting and translational frame; Gap between wheel of adjustment centering rationally and the guide rail, the generation that also can prevent to move additional internal force in the framework improves the force-bearing situation that moves framework, prolongs the service life of framework.
