Abstract
The utility model discloses a floating support device of a rotary kiln riding wheel, which includes a base, a thrust oscillating bearing, a bracket and a support base, wherein the thrust oscillating bearing and the support base are arranged along the center line of the base and positioned at the front and the rear ends of the bottom part of the base respectively; the thrust oscillating bearing is obliquely arranged, the upper end of the thrust oscillating bearing is connected with the base, and the lower end thereof is connected with the bracket; moreover, the rotation center of the thrust oscillating bearing is in the same vertical plane as a contact bus of a belting leather of the riding wheel on the base, and is in the same horizontal plane as the upper end surface of the support base. The floating support device is reliable in use and simple in structure, can efficiently solve the problems of unbalanced load on bearings on both sides caused by non-parallelism of the riding wheel and the belting leather, as well as deviation of the load distribution on the rotary cement kiln support from the design during actual operation, and prolongs the service lives of components including the belting leather and the riding wheel both at the support part.
Description
Technical field
The utility model relates to cement industry and uses the rotary kiln field, relates in particular to a kind of floating support device of supporting roller of rotary kiln.
Background technology
The support system of rotary kiln is the vitals of rotary kiln.As a rule, the support system of a cement rotary kiln has two to three cover supporting arrangements.These supporting arrangements are being born the weight of the fixed proportion of rotary kiln respectively when design.Owing to the foundation settlement inequality of rotary kiln, the alignment error of kiln cylinder body, the adjustment error of wheel band, a series of reasons such as flexural deformation of kiln cylinder body; The bearing load of kiln distributes the situation of off-design anticipation far away, and this has just caused problems such as bearing of conveyor idler overload, the aggravation of wheel band support roller surface abrasion, kiln cylinder body vibration, current of electric increase.So people increase the jackscrew of scalable support roller position on traditional supports, make the problems referred to above to be resolved through manual adjustments like this.But when practical operation, such manual adjustment is not easy to hold, so the various countries technical staff hopes a kind ofly can solve top problem by self-adjusting supporting arrangement through researching and developing.
Begin cement industry from the sixties in last century and successively occurred realizing self-regulating floating support device, but use not extensive by elements such as strength, hydraulic cylinder, rubber supports.All there is such problem in various technology: when increasing from tonality, often sacrifice stability, if guarantee that stability is then not enough from tonality.
Summary of the invention
The utility model is used for solving the problem that the cement rotary kiln bearing load is distributed in real-world operation process off-design, especially solves by the problem of support roller wheel with the not parallel two side bearing unbalance loadings that cause.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the floating support device of supporting roller of rotary kiln comprises base, thrust articulated bearing, support and bearing support; Thrust articulated bearing and bearing support are provided with along the center line, and lay respectively at the rear and front end of base bottom; Thrust articulated bearing is obliquely installed, and its upper end connects base, and the lower end connects support; Support roller wheel band on the pivot of thrust articulated bearing and the base contact bus on same vertical plane, with the upper surface of bearing support on same horizontal plane.
Aforementioned bearing support adopts existing rubber support; Its area and rigidity are bigger; The rubber support level is installed during installation; When the rotary kiln tyre deflection caused it to the amesiality bearing of conveyor idler of pressure of support roller, the pressure of this skew will drive support roller and base rotates around the pivot of thrust articulated bearing, thereby reduce the unbalance loading amount of support roller pressure; Because the rubber support contact-making surface of support plinth is big and axial rigidity is big, make its resistance that base is rotated on a suitable size, so just taken into account the adjustability and the stability of product.
For preventing that excessive horizontal nutation from appearring in base, the left and right sides of base also is provided with auxiliary support, and auxiliary support and base gap are provided with.Auxiliary support also adopts rubber support.
The utility model has the advantages that: use reliable; Simple in structure; Can effectively solve by support roller, take turns problem with the not parallel two side bearing unbalance loadings that cause; And the cement rotary kiln bearing load is distributed in the problem of off-design in the real-world operation process, prolonged the life-span of parts such as supporting place wheel band, support roller.

Fig. 3 is the partial enlarged drawing at thrust articulated bearing place among Fig. 1.
Fig. 4 is the work sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the utility model comprises base 1, thrust articulated bearing 2, support 3 and bearing support 4; Thrust articulated bearing 2 axially is provided with along base 1 with bearing support 4, and lays respectively at the rear and front end of base 1 bottom; Thrust articulated bearing 2 is obliquely installed, and its upper end connects base 1, and the lower end connects support 3; Bearing support 4 is horizontally disposed with; The wheel of the support roller 5 on the pivot of thrust articulated bearing 2 and the base 1 with 6 contact bus on same vertical plane, with the upper surface of bearing support 4 on same horizontal plane.
The pivot of thrust articulated bearing 2 should with the wheel of support roller 5 with 6 contact bus on same vertical plane so that the moment of flexure on the horizontal plane that rotary kiln causes when axial float is 0; The pivot of the upper surface of bearing support 4 and thrust articulated bearing 2 is in same horizontal plane, to guarantee that the axis that support roller is rotated is a level when regulating automatically.
As shown in Figure 2, thrust articulated bearing 2 is arranged along base 1 center line with bearing support 4.The left and right sides at base 1 also respectively is provided with an auxiliary support 7, and auxiliary support 7 is provided with base 1 gap, and the amplitude of oscillation when defining base 1 and on horizontal plane, swinging has excessive beat in order to avoid base 1 on horizontal plane.
As shown in Figure 3, the bottom of thrust articulated bearing 2, promptly standing part links to each other with support 3, and support 3 is fixed on the ground level; The top of thrust articulated bearing 2, promptly movable part links to each other with base 1; Thrust articulated bearing 2 tilts to install to bear whole horizontal loads.
As shown in Figure 4, during work, when support roller 5 is with 6 deflections to cause its suffered load unbalance loading because of wheel, base 1 swing around thrust articulated bearing 2 centers, 4 of bearing supports play the effect of balance and about beam jitter amount in swing process.Under the acting in conjunction of thrust articulated bearing 2 and bearing support 4, the load unbalance loading amount that support roller receives is controlled within the lower scope.
