Abstract
The utility model discloses a self-adaptive oil cylinder of a grate cooler, which comprises an oil cylinder body and a piston rod, wherein the rear end of the oil cylinder body is provided with a rear lug ring for fixing; the front end of the piston rod is provided with a front lug ring for fixing; bearing seats are respectively arranged in inner bores of the rear lug ring and the front lug ring; a spherical plain bearing is arranged in each bearing seat; and each bearing seat is provided with an elastic damping ring for preventing the spherical plain bearing from moving. After the spherical plain bearings replace the original wear-resistant steel jacket, the axial direction of each spherical plain bearing can be adjusted, and the spherical plain bearings can automatically adapt to a fixed hinge pin after the deformation of a shell of the grate cooler, so that the torsion for the oil cylinder when in work due to the deformation of the shell of the grate cooler can be effectively eliminated, the fault of damage of an lug ring on the head part of the oil cylinder is avoided, the service life of the oil cylinder is prolonged, and the problem of loss brought by frequent damage of the oil cylinder due to the deformation of the shell of the grate cooler is thoroughly solved. The self-adaptive oil cylinder of the grate cooler has the advantages of difficulty in damage, safety and reliability.
Description
Technical field
The utility model relates to a kind of oil cylinder that is used for the cooling machine.
Background technique
The cooling machine is one of visual plant during rotary kiln is produced, and the main grog of being responsible in rotary kiln, burning till cools off rapidly in the cooling machine, and is undertaking the conveying task of grog; The cooling Oil cylinder is the critical piece of the power transmission aspect in the grog course of conveying; At work, through hydraulic control system, in predetermined stroke, move reciprocatingly; Receive temperatures involved, cooling engine housing (steel plate manufacturing) can deform gradually; The cooling Oil cylinder that in the past used, as shown in Figure 1, the back earrings 3 of oil cylinder body 1 rear end and preceding earrings 4 endoporus of piston rod 2 front ends stud with wear-resisting steel bushing 6; Wear-resisting steel bushing 6 cooperates with fixed pin shaft again, because its reasons in structure, and axially can not the regulating of wear-resisting steel bushing 6; After the distortion of cooling engine housing, axial variation, the very big torsion of existence between wear-resisting steel bushing and the fixed pin shaft of having taken place of fixed pin shaft; This twisting force has so just caused oil cylinder the situation that the head earrings twists off to occur after use a period of time, the each damage on forward and backward earrings; All to stop the kiln number and hour change, output and quality and coal consumption are all had no small loss.
The model utility content
The utility model technical problem to be solved provides a kind of fragile, not safe and reliable cooling machine self-adapting type oil cylinder.
For solving the problems of the technologies described above; The technological scheme of the utility model is: cooling machine self-adapting type oil cylinder, comprise oil cylinder body and piston rod, and the rear end of said oil cylinder body is provided with the back earrings that is used for fixing; The front end of said piston rod is provided with the preceding earrings that is used for fixing; The endoporus of said back earrings and said preceding earrings is equipped with bearing support, and joint shaft bearing all is installed in the said bearing support, and the circlip that prevents said joint shaft bearing play also is installed on the said bearing support.
As optimized technical scheme, said bearing support is provided with dust-proof cover.
Owing to adopted technique scheme; Cooling machine self-adapting type oil cylinder comprises oil cylinder body and piston rod, and the rear end of said oil cylinder body is provided with the back earrings that is used for fixing; The front end of said piston rod is provided with the preceding earrings that is used for fixing; The endoporus of said back earrings and said preceding earrings is equipped with bearing support, and joint shaft bearing all is installed in the said bearing support, and the circlip that prevents said joint shaft bearing play also is installed on the said bearing support.After replacing original wear-resisting steel bushing with joint shaft bearing; Because axially can adjusting of joint shaft bearing; Can the fixed pin shaft after the cooling engine housing distortion be adapted to automatically, effectively eliminated because of the distortion of cooling engine housing cause oil cylinder work the time torsion, avoided the fault of oil cylinder head earrings damage; Prolong the working life of oil cylinder, thoroughly solved the loss that the oil cylinder frequent breakage that causes because of cooling engine housing distortion is brought.The utlity model has fragile, not safe and reliable advantage.

Fig. 1 is the structural representation that uses the cooling Oil cylinder of wear-resisting steel bushing in the background technique;
Fig. 2 is the utility model embodiment's a structure principle chart;
Fig. 3 is the plan view of Fig. 2.
Among the figure: 1-oil cylinder body; The 2-piston rod; Earrings behind the 3-; Earrings before the 4-; The 5-joint shaft bearing; The wear-resisting steel bushing of 6-.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in Figures 2 and 3, cooling machine self-adapting type oil cylinder comprises oil cylinder body 1 and piston rod 2; The rear end of said oil cylinder body 1 is provided with the back earrings 3 that is used for fixing; The front end of said piston rod 2 is provided with the preceding earrings 4 that is used for fixing, and the endoporus of said back earrings 3 and said preceding earrings 4 is equipped with bearing support, and joint shaft bearing 5 all is installed in the said bearing support; The circlip that prevents said joint shaft bearing 5 plaies also is installed on the said bearing support, and said bearing support is provided with dust-proof cover.Because of the structure of said circlip and said dust-proof cover is a common practise, so locate to repeat no more, also not shown among the figure.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
