Description
Technical Field
The utility model relates to a fully-mechanized coal mining hydraulic support in a coal mine, in particular to a hinged structure between split hydraulic supports.
Background
At present, the technology of the underground hydraulic support of the coal mine is slow to develop, no hydraulic support is matched and applicable, and the working face still adopts a high-grade common mining process. Low yield, more accidents, high labor intensity of workers and severe operation environment. The fully mechanized coal mining equipment is used for replacing a high-grade common coal mining process, the dilemma that the working face of the ultra-thin coal seam is high in labor intensity, low in safety and reliability and low in extraction efficiency is solved, and particularly, serious shortages of coal mining workers are overcome, so that the development of the fully mechanized coal mining hydraulic support for the ultra-thin coal seam is imperative to realize automatic mining of the working face of the ultra-thin coal seam.
Disclosure of Invention
The utility model aims to make up the defects of the prior art and provides a split type hinge structure between hydraulic support frames.
The above object is achieved by the following technical scheme:
the split type hydraulic support inter-frame hinge structure comprises a top beam frame, a base frame and a hydraulic lifting frame, wherein the top beam frame is connected with the base frame through the hydraulic lifting frame;
the top beam frame comprises a front top beam, a rear top beam and an upper connecting plate;
the front support top beam and the rear support top beam are connected through the upper connecting plate by an upper hinge shaft;
the base frame comprises a front frame base, a rear frame base and a lower connecting plate;
the front frame base is connected with the rear frame base through a lower connecting plate by a lower hinge shaft.
The split type hydraulic support frame hinge structure comprises two hydraulic lifting frames, wherein one hydraulic lifting frame is connected between the front support top beam and the front support base, and the other hydraulic lifting frame is connected between the rear support top beam and the rear support base.
The split type hydraulic support frame hinge structure is characterized in that the front support top beam and the rear support top beam are all welded into a box-type variable section structure by high-strength steel plates.
The split type hydraulic support frame hinge structure is characterized in that the front frame base and the rear frame base are composed of two box body plates and a plurality of main ribs connected between the two box body plates.
Advantageous effects
1. The utility model not only can avoid the uneven top and bottom plates to compress the effective working space, but also can facilitate the personnel to walk and overhaul in the bracket.
2. According to the utility model, the two upper connecting plates are arranged between the two split top beams of the hydraulic support, and the two ends of the upper connecting plates are respectively hinged through the pin shafts, so that when the top and bottom plates are uneven, the load is uniformly distributed, and the purpose of quick passing is achieved.
3. The utility model can increase the pressure of the top beam anti-uneven top plate, and simultaneously increase the space and ventilation section of the bracket pedestrians to the maximum extent, thereby being convenient for the operation and maintenance of the bracket; the thicknesses of the top beam and the base are reduced, so that the effective operation space is prevented from being compressed due to uneven top and bottom plates; the bracket is convenient to operate and overhaul the working space for replacing accessories.
