Description
Technical field
This utility model relates to a kind of gear, the coal mining tooth wheel construction of a kind of coal-winning machine, belongs to sphere of life.
Background technology
Coal-winning machine is one of visual plant realizing coal production mechanization and modernization.Mechanical coal mining can alleviate physical work, improve safety, reaches high yield, high efficiency, low consumed purpose.
Coal-winning machine divides sawing formula, planing pattern, drilling formula and milling type four kinds: coal-winning machine is one and integrates machinery, the electric and large-scale complicated system of hydraulic pressure, work under bad environment, the interruption of whole coal work will be caused if there is fault, cause huge economic loss. along with the development of coal industry, the function of coal-winning machine gets more and more, the structure of himself, composition more sophisticated, thus the reason broken down is the most complicated.Double-ended shearer combines the successful experience of domestic and international low seam mining machinery, is the novel high-power low seam mining machinery designed for China's specific national conditions.
Owing to general coal mining environment all compares badly, requirement to coal-winning machine is the highest, while early ensureing efficiently to mine, coal-winning machine to be guaranteed occurs without fault, certainly this simply the most ideally, general coal-winning machine breaks down and mostly is the gear of coal-winning machine and runs into relatively hard formation, or temperature is too high, rupture, or damaged, affect the job schedule of coal mining activity.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that the coal mining tooth wheel construction of a kind of coal-winning machine, uses the pick group of pick combining form, thus solves the problems referred to above.
For achieving the above object, this utility model following technical scheme of offer: the coal mining tooth wheel construction of a kind of coal-winning machine, including pick dish, bearing, twist dish and sealing ring, described pick dish is provided with several pick device groups, described pick device group is provided with the first pick, the second pick and temperature sensor, and described first pick and the second pick are equipped with arc groove.
Further, the arrangement between described pick device group is in staggered helical structure.
Further, there is the angle of alternating expression in the arrangement of described first pick and the second pick.
Further, described temperature sensor is positioned at the inside of pick device group shell, by being electrically connected with the temperature indicator on the control station of coal-winning machine.
Further, the degree of depth of described arc groove arcuate groove is less than 1/4th of place pick radius, and the width of arc is less than 1/3rd of place pick circumference.
Compared with prior art, the beneficial effects of the utility model are: the gear structure of this kind of coal-winning machine is simple, do not change other apparatus structure on coal-winning machine, the application of pick device group, the intensity of the work of single pick can be changed, staggered angle between pick, add the area in pick contact coal seam, the pick device group density when the arrangement of pick dish can greatly reduce a pick single arrangement simultaneously, reduce pick dish weight, the addition of temperature sensing device, allow pick because the fracture that causes of temperature overheating or breakage, there is the prompting of precognition in advance, the coal mining activity making coal-winning machine is highly efficient.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model together with embodiment of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the coal mining tooth wheel construction of a kind of coal-winning machine described in the utility model；
Fig. 2 is the structural representation of the pick of the coal mining tooth wheel construction of a kind of coal-winning machine described in the utility model；
In figure: 1, pick dish；2, bearing；3, pick device group；4, the first pick；5, the second pick；6, dish is twisted；7, sealing ring；8, temperature sensor；9, arc groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment; technical scheme in this utility model embodiment is clearly and completely described; obviously; described embodiment is only a part of embodiment of this utility model; rather than whole embodiments; based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of technical scheme of this utility model offer: the coal mining tooth wheel construction of a kind of coal-winning machine, including pick dish 1, bearing 2, twist dish 6 and sealing ring 7, pick dish 1 is provided with several pick device groups 3, pick device group 3 is provided with the first pick the 4, second pick 5 and temperature sensor 8, and the first pick 4 and the second pick 5 are equipped with arc groove 9.
Arrangement between pick device group 3, in staggered helical structure, allows the surface of work surface all standing pick dish 1 of all of pick, staggered helical structure arrangement be much smaller than single horizontally arranged weight and the comparison of resistance that is subject to during the work of pick dish is little.
There is the angle of alternating expression in the arrangement of the first pick 4 and the second pick 5, the intensity of the work of single pick can be changed, staggered angle between pick, add the area in pick contact coal seam, the pick device group density when the arrangement of pick dish can greatly reduce a pick single arrangement simultaneously, reduce pick dish weight.
Temperature sensor 8 is positioned at the inside of pick device group 3 shell, by being electrically connected with the temperature indicator on the control station of coal-winning machine, operator are allowed to know the operating temperature of pick in real time, coal-winning machine can be closed if desired, reduce pick because of the probability of the too high infringement of temperature, saving maintenance cost and maintenance time.
The degree of depth of arc groove 9 arcuate groove is less than 1/4th of place pick radius, the width of arc is less than 1/3rd of place pick circumference, the setting of arc groove 9, the resistance being subject to during pick work can be reduced, the control of size, can effectively prevent breakage and the peeling of alloy coat.
The beneficial effects of the utility model are: the gear structure of this kind of coal-winning machine is simple, do not change other apparatus structure on coal-winning machine, the application of pick device group, the intensity of the work of single pick can be changed, staggered angle between pick, add the area in pick contact coal seam, the pick device group density when the arrangement of pick dish can greatly reduce a pick single arrangement simultaneously, reduce pick dish weight, the addition of temperature sensing device, allow pick because the fracture that causes of temperature overheating or breakage, there is the prompting of precognition in advance, the coal mining activity making coal-winning machine is highly efficient.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
