Abstract
The invention discloses a novel traction driving structure of a coal cutting machine. The novel traction driving structure is characterized in that the traction driving structure is composed of a driving sprocket, a chain and a pulley, wherein the chain bypasses the pulley and goes around the driving sprocket, and the chain is driven by the driving sprocket; an axle hole is formed in the middle part of the driving sprocket, a key groove is formed inside the axle hole, a chain groove for enabling the chain to bypass the driving sprocket is formed in the side circumference of the driving sprocket, an axle hole is formed at the center of the pulley, and a chain groove for enabling the chain to bypass to drive the pulley to rotate is formed in the side circumference of the pulley. The novel traction driving structure solves the problem caused by steel rope traction, can achieve high-efficiency and energy-saving effects, is safe and reliable to operate, is convenient to operate and use, and can improve the working efficiency and prolong the service life, wherein the efficiency and the speed are improved by 30%, and the energy is saved by 30%.
Description
Technical field
The present invention relates to a kind of Traction Drive field of coalcutter, is specifically a kind of coalcutter novel traction drive mechanism.
Background technology
In recent years, China's coal-cutting machinery industry development is swift and violent, ends nearly 24 of national coal-cutting machinery manufacturing enterprises in 2010, approximately more than 800 of volume of production and marketing, and production capacity reaches 1500 left and right.From domestic coal machine competition situation, China Mei Ji manufacturing enterprise is interfereed with the development slowly by the planned economy era, and not only technical level is lower, and product is single.Although skill upgrading is in recent years very fast, but compare with external coal machine giant, the reliability and stability of China's coal mining machinery equipment complete machine are still not strong, the top brand that lacks industry, in financial strength and R&D capability, also has one section of gap with international most advanced level, the production aspect of colliery extractive equipment is larger with external gap in the open, the large current real picture of Er Buqiangshi China's coal machine profession.
Coal-winning machine is a large-scale complicated system that integrates 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.Along with the development of coal industry, the function of coal-winning machine is more and more, the structure of himself, composition more sophisticated, thereby the reason breaking down is also thereupon complicated.For cut coal equipment, former with wire rope traction, maintenance energy consumption is large, and effect speed is low, and inconvenience is used in operation and operation, thereby operating efficiency is low, therefore need to be improved.
Summary of the invention
The object of the invention is to provides a kind of coalcutter novel traction drive mechanism at this; The problem existing with wire rope traction before solving; Now for Novel chain traction has reached energy-efficient, it is 30% energy-conservation 30% safe and reliable to operation, easy for operation that effect speed exceeds, thereby improve its operating efficiency, increases the service life.
The present invention is achieved in that a kind of coalcutter novel traction drive mechanism of structure, it is characterized in that: this Traction Drive structure consists of drive sprocket, chain, pulley; Chain is walked around pulley, around drive sprocket, by drive sprocket, drives chain; Described drive sprocket middle part is axis hole, and axis hole inside, with keyway, has the chain of walking around drive sprocket for chain on the circumference of drive sprocket side; Described pulley center is axis hole, has chain and walk around the chain rotating with movable pulley on pulley flanks circumference.
The invention has the advantages that: coalcutter novel traction drive mechanism of the present invention, be applied in cut coal equipment, through improvement, reasonable in design, utilization ratio is high, and operating cost reduces, and is widely used in many cut coal equipment.The present invention improves, the problem existing with wire rope traction before solving; Now for Novel chain traction has reached energy-efficient, it is 30% energy-conservation 30% safe and reliable to operation, easy for operation that effect speed exceeds, thereby improve its operating efficiency, increases the service life.

The specific embodiment
Below in conjunction with accompanying drawing 1-6, the present invention is described in detail, and the technical scheme in the embodiment of the present invention is clearly and completely described, and obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 1-6, the invention provides a kind of coalcutter novel traction drive mechanism, through improvement,, being applied in cut coal equipment, this Traction Drive structure is implemented in such a way: drive sprocket 3, chain 1, pulley 2, consist of; Chain 1 is walked around pulley 2 around drive sprocket 3, by drive sprocket, drives chain; Described drive sprocket 3 middle parts are axis hole 4, and axis hole 4 inside, with keyway 5, have the chain 6 of walking around drive sprocket 3 for chain 1 on drive sprocket 3 side circumference; Described pulley 2 centers are axis hole 7, have chain 1 and walk around the chain 8 rotating with movable pulley 2 on pulley 2 side circumference.
Coalcutter novel traction drive mechanism of the present invention, is applied in cut coal equipment, through improvement, and reasonable in design, utilization ratio is high, and operating cost reduces, and is widely used in many cut coal equipment.The present invention improves, the problem existing with wire rope traction before solving; Now for Novel chain traction has reached energy-efficient, it is 30% energy-conservation 30% safe and reliable to operation, easy for operation that effect speed exceeds, thereby improve its operating efficiency, increases the service life.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
