Abstract
The invention discloses a scraper conveyer adjustable with the height of a pin row track adjustable. The scraper conveyer comprises a groove, pin row track bases, the adjustable pin row track and a pin shaft. The pin row track bases are welded to the groove, the diameters of two sets of holes in the adjustable pin row track are the same, and the two sets of holes are formed in the two horizontal planes respectively. The pin row track and the pin row track bases can be hinged to the two sets of holes in the vertical direction through the pin shaft respectively. When the thickness of the coal seam of a working face varies largely, and the thickness of the lowest coal seam is small, so that the fully-mechanized coal mining requirements are difficult to meet (the condition appears frequently in the southwestern region), the pin row track bases can be adjusted to be hinged to the two sets of corresponding holes in the pin row track, meanwhile, sliding shoes at corresponding heights of a coal mining machine are replaced, in this way, the height H2 of the surface of the coal mining machine and the coal-passing space height H1 can be adjusted, and then the coal mining requirements are met; the requirement for increasing the recovery ratio or guaranteeing coal mining quality is met without replacing the scraper conveyer, the input cost is greatly reduced, and the production efficiency is greatly improved.
Description
Technical field
The invention belongs to coal mine fully-mechanized mining technical field, be specifically related to a kind of underground coal mine transportation equipment.
Background technology
Along with the development of coal mine fully-mechanized mining technology, obtain in comprehensive mechanical coal mining and generally used.General thinner in the coal seam of southwestward, and part Coal Seam Thickness Change comparatively large (the such as coal seam of mean thickness 2m, Coal Seam Thickness Change can reach 0.9 ~ 2.8m).Based on above-mentioned coal seam feature, if adopt thinner seam slat conveyer, when mining height is larger, coal spatial altitude will be caused not enough, if and adopt thick coal seam slat conveyer, when mining height is lower, because machine height is higher, the survival space between coalcutter and hydraulic support top beam can be caused again not enough.In order to address these problems, the following dry method of general employing: is strengthen minimum coal mining height, cutting certain thickness spoil, thus has a strong impact on coal mining quality; Two is reduce maximum coal mining height, gives up certain thickness coal seam, can waste resource so again, reduce the rate of extraction; Three is change slat conveyer when Coal Seam Thickness Change, but not only considerably increases fund input like this, but also can the therefore waste of the human and material resources caused, and has a strong impact on production efficiency.
Summary of the invention
The technical barrier that patent of the present invention will solve be to provide a kind of Coal Seam Thickness Change larger time, use same set of slat conveyer to solve the relevant difficult problem of fully-mechanized mining working.Namely can ensure enough coal spatial altitudes excessively when mining height is larger, thus ensure the rate of extraction; And mining height lower time under the prerequisite ensureing survival space, cut or do not cut spoil less, thus ensure a kind of slat conveyer of coal mining quality.
In order to solve above-mentioned technical barrier, the present invention devises a kind of slat conveyer of adjustable pin row rail height, describedly comprise cell body (1), pin row rail chair (2), adjustable pin row rail (3) and bearing pin (4), described pin row rail chair is welded on cell body baffle, and described adjustable pin row rail (3) is hinged by bearing pin (4) and pin row rail chair (2).
The upper two groups of bore dias of described adjustable pin row rail (3) are identical, and upper one group of hole and next group hole are on upper and lower two horizontal surfaces respectively.
Described pin row rail (3) is hinged by bearing pin (4) and pin row rail chair (2).
After adopting said structure, because two groups of holes on adjustable pin row rail (3) lay respectively on two highly different horizontal surfaces, described adjustable pin row rail (3) is hinged by bearing pin (4) and pin row rail chair (2).When coal-face coal seam thickness changes, height is adjusted by adjusting the articulated position adjustable pin row rail (3) being in two groups of holes on two horizontal surfaces and pin row rail chair (2), change corresponding piston shoes to coalcutter simultaneously and adjust coal spatial altitude H1 and machine height H2 (and without the need to changing slat conveyer) to reach, thus greatly save input cost, while guarantee coal mining quality and the rate of extraction, also substantially increase work efficiency.
Foregoing invention structure is simple, practical, obtains good effect in actual use.

Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1 is state when mining highly lower, and now scrapper conveyor crosses coal spatial altitude H1 and coalcutter machine height H2 is lower, guarantees the survival space between itself and hydraulic support.
The slat conveyer of this adjustable pin row rail height comprises cell body (1), pin row rail chair (2), adjustable pin row rail (3) and bearing pin (4).Described adjustable pin row rail (3) is arranged on pin row rail chair (2), hinged with the hole, one group, top on adjustable pin row rail (3) by bearing pin (4), now adjustable pin row rail is in low-end trim, and coalcutter rides on adjustable pin row rail (3) and intermediate channel cell body, be equipped with the piston shoes of a corresponding height to coalcutter when this state.
Embodiment 2: with reference to accompanying drawing 2 is states when mining highly higher, and now to cross coal spatial altitude H1 coalcutter machine height H2 larger for slat conveyer.
The slat conveyer of this adjustable pin row rail height comprises cell body (1), pin row rail chair (2), adjustable pin row rail (3) and bearing pin (4).Described adjustable pin row rail (3) is arranged on pin row rail chair (2), hinged with the hole, one group, bottom on adjustable pin row rail (3) by bearing pin (4), now adjustable pin row rail is in high-end trim, and coalcutter rides on adjustable pin row rail (3) and intermediate channel cell body, change the piston shoes of a corresponding height to coalcutter when this state.
The protection domain of this patent is not limited in above-mentioned exemplifying embodiment; obvious those skilled in the art is under the condition not departing from the art of this patent main points; (such as double-row hole changes many rounds into be easy to carry out various change and distortion to this patent; or double-row hole or many rounds are arranged on pin row rail chair, or adopt the method etc. changing pin row rail).These distortion are all within the protection domain of this patent.
