Although, also there is at present part producer to adopt hydraulic ram as the levelling gear of slat conveyer, it has not only increased use cost, and complex structure, and complex operation is not easy to loading and unloading and uses, and fault rate is high.
Therefore, how to design a kind of coal wall caving that can reduce and avoid exploiting driving surface, and safe and reliable, simple to operate, be convenient to load and unload, the levelling gear of the slat conveyer of failure rate is low, be present association area personnel's problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of levelling gear of slat conveyer is provided, it not only can adjust the levelness of slat conveyer on the roadway floor of exploitation driving surface, make the rib after coalcutter cuts be the nature vertical, reduce and avoid coal wall caving, and simple in structure, easy and simple to handle, be convenient to loading and unloading, failure rate is low.
the technical solution of the utility model is: a kind of levelling gear of slat conveyer, comprise slat conveyer, hydraulic support, slat conveyer is provided with the driving surface scraper-trough conveyer, hydraulic support is provided with the pushing and sliding bar, coalcutter is positioned on slat conveyer, hinged by regulating arm between described driving surface scraper-trough conveyer and pushing and sliding bar, described regulating arm is curved shape, it is hinged by bearing pin and driving surface scraper-trough conveyer that the one end arranges hinge hole, other end both sides are the symmetric arms along crooked convex arc limit extension, on two symmetric arms, hinge hole is set, the pushing and sliding bar of hydraulic support is between two symmetric arms, hinge hole by bearing pin and symmetric arms is hinged.
The hinge hole at described regulating arm two ends lays respectively on two radiuses on crooked convex arc limit, and the interval angle [alpha] between two hinge holes is 120～125 degree.
Two symmetric arms and regulating arm are one-body molded.
Two symmetric arms and regulating arm are welded and fixed.
adopt technique scheme: due to hinged by regulating arm between described driving surface scraper-trough conveyer and pushing and sliding bar, described regulating arm is curved shape, it is hinged by bearing pin and driving surface scraper-trough conveyer that the one end arranges hinge hole, other end both sides are the symmetric arms along crooked convex arc limit extension, on two symmetric arms, hinge hole is set, the pushing and sliding bar of hydraulic support is between two symmetric arms, hinge hole by bearing pin and symmetric arms is hinged, the thrust that the pushing and sliding bar is produced can pass to the driving surface scraper-trough conveyer by regulating arm, regulating arm utilizes the crank principle, one end of driving surface scraper-trough conveyer is made progress after the lifting certain altitude, and be certain angle between the roadway floor of exploitation driving surface, make the driving surface scraper-trough conveyer remain level, thereby make the rib after the coalcutter cutting be the nature vertical, actv. has been avoided rib generation wall caving phenomenon, not only can prevent that coal wall caving from hurting sb.'s feelings, and can protect the parts of coalcutter.
The levelling gear of the utility model slat conveyer not only can be adjusted the levelness of slat conveyer on the roadway floor of exploitation driving surface, make the rib after coalcutter cuts be the nature vertical with the roadway floor of exploiting driving surface, reduce and avoid rib partially to help, and simple in structure, easy and simple to handle, be convenient to loading and unloading, failure rate is low.
