Description
Technical field
The utility model belongs to coal mining device technical field, relates to a kind of coal-winning machine, particularly relates to a kind of coarse pitch Walk Part of Shearer.
Background technology
Coal-winning machine is the domestic and international direct equipment for coal mining at present, and primarily of the composition such as cutting units and running part, cutting units is responsible for broken coal and is coaling, and running part is responsible for driving coal-winning machine to move at work plane.Because ocurrence of coal seam has certain inclination angle usually, the climbing capacity that therefore running part of coal-winning machine must be certain.Through exploitation for many years, what inclination angle was less easily adopt high seam resource constantly reduces, and thick seam large mining height working face inclination angle presents the trend constantly increased.
But when the work plane inclination angle that high-power coal cutter runs is greater than 15 °, the fault rate of running part obviously increases, and the application life of road wheel and guide slip shoe sharply declines.Particularly when work plane inclination angle is greater than 25 °, road wheel and guide slip shoe life-span, not only repair cost was high even less than one month, work plane also can be caused to stop production, cause heavy economic losses.Therefore, high-power coal cutter tractive unit has become the exploitation constraining inclination high-seam working face, force coal mining enterprise can only be produced by the mode of the separate zone production of middle low power coal-winning machine or top coal caving, cause the situation that production efficiency is low, recovery ratio is low.
In view of this, nowadays in the urgent need to designing a kind of coarse pitch Walk Part of Shearer, be different from existing 151mm, 172mm pitch, and guarantee the hydraulic support being applied to current 1.75m groove width.Only having by carrying out innovative design to road wheel and these two main weak elements of guide slip shoe, improving its intensity and reliability, just can guarantee the reliability of running part entirety, ensure that high-power coal cutter is in inclined plane stable operation.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of coarse pitch Walk Part of Shearer, can improve intensity and the application life of road wheel.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
