Abstract
The invention discloses a force-transferring intermediate device inside a rotary cement kiln. The intermediate device comprises a centering rod, an ejecting rod, a protecting cover and a piston rod connecting piece, wherein compression springs are arranged at one end and in the middle of the centering rod respectively, one port, where the compression spring is arranged, of the centering rod is movably connected with an elastic check ring, the elastic check ring is fixedly connected with a thrust bearing, four bearings are symmetrically arranged at two ends of the thrust bearing, the ejecting rod covers a system formed by the centering rod and the thrust bearing, and two bearings are arranged in positions where the bearings are connected with the ejecting rod. The intermediate device has the benefits as follows: the structure is simple, the thrust bearing adopts an arched structure, so that the stress strength of the bearings is increased, and the service life of the rotary cement kiln is increased; the centering rod adopts a hollow wood structure, a larger gap is reserved between the centering rod and the ejecting rod, accordingly, the condition that the centering rod is stuck in an inner hole of the ejecting rod due to high-temperature expansion is avoided, besides, the quality of the device is effectively reduced due to the hollow structure, and the unnecessary loss during production of the rotary kiln is reduced.
Description
Technical field
The present invention relates to a kind of power transmission middle device of cement rotary kiln inside.
Background technology
Along with rapid development of economy in recent years, civil construction industry is more and more hotter, and the demand of cement is increasing, and rotary kiln, except calcination clinker, is also used for calcined clay, lime stone and carry out slag drying etc.; During refractory material is produced, adopt rotary kiln calcination raw material, its dimensionally stable, intensity are increased, and reprocess shaping, rotary kiln refers to rotary calcining kiln, belongs to building equipment class, and rotary kiln can be divided into cement kiln, chemical metallurgy kiln and limekiln by material handling difference.
At building materials, metallurgical, chemical industry, in many production industries such as environmental protection, revolving drum equipment is used to carry out machinery to solid material widely, physical or chemical treatment, this kind equipment is called as rotary kiln, as the nucleus equipment of cement production enterprise, under the prerequisite of normal operation not interrupting kiln, the various detections of rotary kiln are all being developed to mobilism, the tugboat axle during but the direct ejection of hydraulic cylinder piston rod can not be used to rotate, therefore just there is the power transmission middle device of novel rotary kiln inside, in the middle device design process of rotary kiln novel mechanical structures, when axial force measuring device uses, the motive force of hydraulic cylinder will be applied to one end of tugboat axle, to balance the axial force suffered by tugboat, make it the state reaching stress balance, if the motive force of hydraulic cylinder can not act on the axis of tugboat axle, so tugboat axle moment can be given while giving tugboat axle applied thrust, the accuracy of measurement result is so not only made to reduce, also may be destroyed supporting construction when thrust is larger, so the effect of power transmission middle device is exactly guide penetrator ram, the thrust of hydraulic cylinder is applied to drags in axle stub, but the centering rod in traditional power transmission middle device is all made up of aluminum metal usually, the degree of usual metal temperature influence is larger, therefore centering rod can be caused to be stuck in penetrator ram endoporus because of high-temperature expansion, thus the unnecessary loss in causing rotary kiln to produce.
Summary of the invention
The object of this invention is to provide a kind of power transmission middle device of cement rotary kiln inside.
The technical solution adopted in the present invention is:
A kind of power transmission middle device of cement rotary kiln inside, comprise centering rod, penetrator ram, protective cover and piston rod connector, described centering rod one end and middle part are respectively equipped with Compress Spring, the port activity that described centering rod is provided with Compress Spring connects circlip, described circlip is fixedly connected with thrust bearing, described thrust bearing two ends are arranged with 4 bearings, described penetrator ram wraps the system of centering rod and thrust bearing composition, described bearing and penetrator ram junction arrange two bearing holder (housing, cover)s, described penetrator ram connects butterfly spring near thrust bearing one end, penetrator ram top corresponding to described thrust bearing two ends is provided with two protective covers, described two protective cover one end are fixed with bolt respectively, described thrust bearing is domes.
Described centering rod is hollow wood construction.
Comparatively wide arc gap is left between described centering rod and penetrator ram.
The invention has the beneficial effects as follows: structure is simple, adopt the thrust bearing of domes, what increase bearing is subject to force intensity, improve the life-span of equipment, centering rod adopts hollow wood construction, and leaves larger space between centering rod and penetrator ram, avoids the situation because high-temperature expansion causes centering rod to be stuck in penetrator ram endoporus, and hollow-core construction effectively decreases the quality of device, decrease the unnecessary loss in rotary kiln production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, centering rod, 2, penetrator ram, 3, Compress Spring, 4, protective cover, 5, circlip, 6, thrust bearing, 7, bearing holder (housing, cover), 8, butterfly spring, 9, bolt, 10, piston rod connector, 11, bearing.
Detailed description of the invention
As shown in Figure 1, the power transmission middle device of a kind of cement rotary kiln inside of the present invention, comprise centering rod 1, penetrator ram 2, protective cover 4 and piston rod connector 10, centering rod 1 one end and middle part are respectively equipped with Compress Spring 3, the port activity that centering rod 1 is provided with Compress Spring 3 connects circlip 5, circlip 5 is fixedly connected with thrust bearing 6, thrust bearing 6 two ends are arranged with 4 bearings 11, penetrator ram 2 wraps the system of centering rod 1 and thrust bearing 6 composition, bearing 11 and penetrator ram 2 junction arrange two bearing holder (housing, cover)s 7, penetrator ram 2 connects butterfly spring 8 near thrust bearing 6 one end, penetrator ram 2 top corresponding to thrust bearing 6 two ends is provided with two protective covers 4, two protective cover 4 one end are fixed with bolt 9 respectively, thrust bearing 6 is domes, centering rod is hollow wood construction, comparatively wide arc gap is left between centering rod and penetrator ram.
The invention has the beneficial effects as follows: structure is simple, adopt the thrust bearing of domes, what increase bearing is subject to force intensity, improve the life-span of equipment, centering rod adopts hollow wood construction, and leaves larger space between centering rod and penetrator ram, avoids the situation because high-temperature expansion causes centering rod to be stuck in penetrator ram endoporus, and hollow-core construction effectively decreases the quality of device, decrease the unnecessary loss in rotary kiln production.
