Abstract
The utility model relates to an automatic lubricating system. The automatic lubricating system comprises a power source, a spring oil cylinder, a device for accommodating lubricating grease, and a hinge point structure, wherein the power source is connected with the spring oil cylinder; the spring oil cylinder is connected with the device for accommodating the lubricating grease through a first one-way valve; the spring oil cylinder is connected with a grease centralized distribution body through a second one-way valve; and the grease centralized distribution body is connected with the hinge point structure. By using the automatic lubricating system, the problems of the abrasion of a hinge pin roll and a shaft sleeve, poor lubrication of a bearing and the like on a coal-winning machine caused by the reason that the lubricating grease of the hinge pin roll and the bearing in a walking box is not filled in time are solved. The reliability of the coal-winning machine is improved; the automation level of the coal-winning machine is improved; and labor intensity of workers is lightened. Simultaneously, the automatic lubricating system has great significance for improving the lubricating technology.
Description
Technical field
The utility model relates to a kind of automatic lubricating system, relates in particular to a kind of automatic lubricating system of grease, belongs to the coal-cutting machinery equipment technical field.
Background technique
Coal winning machine is the core equipment on the fully mechanized mining face, and its reliability directly affects the production capacity of working surface.Each hinging pin shaft is the filling that regularly is lubricated grease by the workman according to the requirement of equipment manufacturing with the lubricated traditional form of walking case inner bearing in the coal mining; But because the operating conditions on the working surface is more abominable, not only also there are potential safety hazard in dark, narrow space but also the position of annotating individually.Also have indivedual mine managerial confusions, the not high factor of miner's quality to cause lubricant grease regularly not annotate on request in addition, thereby cause the heavy wear of bearing pin and axle sleeve, problems such as the insufficient lubrication of bearing have influenced the reliability of equipment greatly.
Summary of the invention
The utility model provides a kind of automatic lubricating system to untimely bad deficiencies of equipment lubrication that causes of grease lubrication place oil addition such as hinging pin shaft on the coal winning machine and walking case inner bearings.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of automatic lubricating system comprises power source, spring oil cylinder, the device that holds lubricant grease and hinge structure; Said power source links to each other with the spring oil cylinder; Said spring oil cylinder links to each other with the device that holds lubricant grease through first one-way valve; Said spring oil cylinder is concentrated through second one-way valve and grease and is divided part to link to each other, and said grease is concentrated and divided part to link to each other with the hinge structure.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said hinge structure comprises a hinge or a plurality of hinges.
Further, said hinge is the hinging pin shaft or the interior all bearing of the case of walking of joint, oil cylinder and the traction joint of connection bearing pin, oil cylinder and rocking arm between rocking arm and the traction housing.
Further, said power source links to each other with the spring oil cylinder through throttle valve.
Further, said power source links to each other with the spring oil cylinder through reduction valve.
Further, said power source links to each other with reduction valve through throttle valve, and said reduction valve links to each other with the spring oil cylinder.
The beneficial effect of the utility model is: the utility model automatic lubricating system has not only solved the untimely bad problem of equipment lubrication that causes of grease lubrication place oil addition such as hinging pin shaft and walking case inner bearing on the coal winning machine; And the reliability and the automatization level of coal winning machine have been improved; Alleviated working strength of workers; Reduced workman's potential safety hazard, to improving the development of lubrication technology, great reference has been arranged simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model automatic lubricating system.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; Lubrication system comprises power source 1, spring oil cylinder 4, holds the device 6 and the hinge structure 9 of lubricant grease; Power source 1 links to each other with spring oil cylinder 4 with reduction valve 3 through throttle valve 2, and spring oil cylinder 4 links to each other with the device that holds lubricant grease 6 through first one-way valve 5, and spring oil cylinder 4 is concentrated through second one-way valve 7 and grease and divided part 8 to link to each other; Grease is concentrated and is divided part 8 to link to each other with hinge structure 9, and hinge structure 9 can comprise that a hinge also can comprise a plurality of hinges.Hinge is that the hinging pin shaft of rocking arm and joint, oil cylinder and the traction joint of drawing connection bearing pin, oil cylinder and rocking arm between the housing or the interior all bearings of the case of walking etc. need lubricated hinging par, lubricates the node number and does not limit.
Automatic lubricating system is by means of the power of hydraulic power unit on the coal winning machine; When rocking arm raises; Pressure oil gets into the rodless cavity of power source 1, and also through the no spring chamber of another duct on power source 1 rodless cavity through throttle valve 2 and reduction valve 3 entering spring oil cylinders 4, overcome has the inner spring force piston motion of spring chamber to pressure oil simultaneously; Lubricating grease in the spring chamber is pressed to grease through second one-way valve 7 concentrates in the branch part 8, thereby realize centralized lubrication hinge structure 9.After rocking arm was heightened end, because power source 1 rodless cavity communicates with fuel tank through operating valve, so power source 1 rodless cavity pressure is zero, thereby spring oil cylinder 4 no spring cavity pressures also were zero.This moment, piston moved to other direction under the effect of spring, the reduction of no spring cavity pressure, and lubricant grease gets into through first one-way valve 5 under the barometric pressure effect again has the spring chamber.So each rocking arm goes up and down all can realize once the self oiling to bearing pin.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
