Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, below according to attached drawing in conjunction with next The utility model is described in further detail.

As shown, a kind of six sides Rock Drilling Arm stretching structure, it is flexible outer including six side's telescopic inner sleeves 1, six sides Set 2, side adjusting pad 4, side wearing plate 5, upper lower guide plate 6, upper and lower adjusting pad 7, upper and lower wearing plate 8, stretches side guide plate 3 Oil cylinder 9, lubricating cup 10, sunk screw 11, pin shaft 12, hexagon socket head cap screw 13, the six sides telescopic inner sleeve are inserted into the flexible housing of six sides In, the side wearing plate, upper and lower wearing plate setting six side's telescopic inner sleeves, six sides stretch housing between, the side guide plate, on Lower guide plate is separately positioned on side wearing plate, upper and lower wearing plate outside, and the side adjusting pad, upper and lower adjusting pad are separately positioned on side Guide plate, on the inside of upper lower guide plate, the lubricating cup is arranged in the guide plate of side, and sunk screw is fixed on lower guide plate and up and down Between wearing plate, then its six side flexible interior (outer) is applied by pin shaft by telescopic oil cylinder and is connected, driven by the way that telescopic oil cylinder is flexible Six side's telescopic inner sleeve stretching operations, the six sides telescopic inner sleeve, the flexible housing fit clearance of six sides are by side guide plate, side tune Whole pad, side wearing plate, upper lower guide plate, upper and lower adjusting pad, upper and lower wearing plate, sunk screw, hexagon socket head cap screw adjust four sides Gap, then from lubricating cup injection lubricating grease run it uniformly, when side wearing plate and upper and lower wearing plate abrasion to a certain degree after, can lead to More side change adjusting pad and upper and lower adjusting pad (using the adjusting pad of different-thickness) are crossed to adjust gap, keep six side's telescopic inner sleeves and The flexible housing gap of six sides is uniform.

The six sides telescopic inner sleeve and the flexible housing of six sides, are a kind of hexagonal structures, it can be spelled by two pieces bending plate Weldering or integral cold drawing take global unique six square materials, and rigid yield strength is significantly larger than four directions and circular configuration, equally The space of size, six square materials of configuration can make entire drill boom carry bigger weight.

Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to specific embodiment The utility model is described in detail, those skilled in the art should understand that, it can be to the skill of the utility model Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical scheme of the present invention, should all be covered In the protective scope of the claims of the utility model.
