Description
Technical field
The utility model relates to technical field of mining equipment, particularly relates to a kind of coal-winning machine caterpillar belt structure.
Background technology
Coal-winning machine is one and integrates large-scale complicated system that is mechanical, electric and hydraulic pressure, and work under bad environment, will cause the interruption of whole coal work if there is fault, cause huge economic loss.Coal-winning machine realizes one of coal production mechanization and modern visual plant.Mechanical coal mining can alleviate manual labor, improve safety, reaches high yield, high efficiency, low consumed object.Coal-winning machine divides sawing formula, planing pattern, drilling formula and milling type four kinds.Along with the development of coal industry, the function of coal-winning machine gets more and more, the structure of himself, composition more sophisticated, and the reason thus broken down is also thereupon 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.
From the geographical situation of China, many mountains, hilliness area, particularly on the Northeast of China, Yunnan, Guizhou, Sichuan, Xinjiang and other places, these places have found the coalfield of a lot of rich reserves successively, because of by the impact of these regional natural geological conditionss, institute finds that coal seam is main mainly with 600mm-1000mm girdle highly.Adopt coal mining machine crawler at present, but crawler belt of the prior art is generally mounted between two Athey wheels, what show in the process of walking is heavier more, simultaneously when coal mining activity in tunnel is sent in its walking in the coal seam of hollow formula, and poor stability.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of coal-winning machine caterpillar belt structure, can improve its stable working.
The utility model is achieved through the following technical solutions:
A kind of coal-winning machine caterpillar belt structure, comprise crawler belt, described crawler belt arrangement mode triangular in shape is arranged on driving wheel, driven pulley I, between driven pulley II, described driving wheel, driven pulley I and driven pulley II distribution triangular in shape, and driven pulley I and driven pulley II are symmetrically distributed in the both sides of driving wheel, described driving wheel offers mounting groove along its circumference, in mounting groove, connecting rod I is rotatably installed, described connecting rod I is rotatably connected by bearing pin and connecting rod II, described connecting rod II and driven pulley I, driven pulley II connects, thus drive driven pulley I and driven pulley II to rotate by driving wheel.
As optimal technical scheme of the present utility model, the inner surface of described crawler belt is plane and is arranged on driving wheel, between driven pulley I and driven pulley II, the external surface of described crawler belt is evenly provided with several projections along its length.
As optimal technical scheme of the present utility model, in described driving wheel, driven pulley I and driven pulley II, all bearing is installed.
As optimal technical scheme of the present utility model, described driven pulley I is identical with the size of driven pulley II, and the size of described driving wheel is greater than the size of driven pulley I.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to use, creatively be provided with driving wheel, driven pulley I and driven pulley II, and distribution triangular in shape, mode triangular in shape for crawler belt is arranged between three wheels, when sending coal mining activity in tunnel in coal seam, its stability can be improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-crawler belt; 2-projection; 10-driving wheel; 20-driven pulley I; 30-driven pulley II; 40-mounting groove; 50-connecting rod I; 60-bearing pin; 70-connecting rod II.
Detailed description of the invention
