Abstract
The utility model relates to a suspended-moving support with a deflection adjusting device, which comprises a main beam and an auxiliary beam. The suspended-moving support is characterized in that the deflection adjusting device is arranged on the support and comprises a hydraulic oil cylinder which is fixedly connected to the main beam or the auxiliary beam. With the hydraulic deflection adjusting device, the suspended-moving support can correct the appeared deflection by rapidly utilizing the hydraulic oil cylinder for supplying power and lifting the top beam of the suspended-moving support to move toward the required direction so as to keep the support be in good working state all the time and guarantee the safe production of a working surface with the reliable supporting quality; the utility model has simple structure, large deflection adjusting range, high adaptability, good controllability, safety and reliability, and can greatly improve the working efficiency and reduce the labor intensity of workers.
Description
Technical field:
The utility model relates to the suspension device under a kind of mine, particularly a kind of cantilever support.
Background technology:
At present, under the mine roof timbering of coal-face some be to rely on some to have the cantilever support of certain frame distance to finish as main supporting, every cantilever support comprises four (or six) supporting legs and two crossbeams, supporting leg is a hydraulic prop, two crossbeams are called girder and auxiliary girder, or and are called back timber.In the work plane construction, cantilever support usually needs to move, and is commonly referred to " moving frame "; Cantilever support is after moving frame; usually deflection can appear; need to adjust; the adjustment of vertical direction; hydraulic prop can be finished easily fast; but the translation adjustment of back timber is difficulty comparatively then, and at present to adjust the way of deflection be to draw with bottle gouard moved by hands, by the manually-operated cucurbit to finish to back timber, this mode exist cucurbit need carry back and forth, operate inconvenience, tuningout speed slowly, inefficiency, uneasy congruent defective.
Summary of the invention:
The purpose of this utility model provide a kind of back timber fast tuningout, significantly improve work efficiency and the safe and reliable cantilever support that has deviation correcting device.
The realization the technical solution of the utility model is, a kind of cantilever support that has deviation correcting device comprises girder and auxiliary girder, it is characterized in that support is provided with deviation correcting device, and described deviation correcting device comprises the hydraulic jack that is fixed on girder or the auxiliary girder.
The utility model adopts the hydraulic pressure deviation correcting device, the power that can utilize hydraulic jack to provide rapidly, the back timber of traction cantilever support moves to the direction that needs move, and the skewness that occurs is corrected fast, makes support be in good working order all the time, guarantee the safety in production of work plane with reliable supporting quality, the utility model is simple in structure, and deflection-regulating range is big, and compliance is strong, handling good, safe and reliable.The utility model can increase substantially operating efficiency, reduces labor strength.
Description of drawings:
Fig. 1 is the structural representation that the utility model is overlooked state; Because the deviation correcting device main body is blocked by the outer of beam, and is invisible, but for the ease of expression, the invisible part of deviation correcting device is all represented with solid line.
Number in the figure: 1 hydraulic jack, 2 piston rods, 3 pull ropes, 4 draw rings, 5 hooks, 6 angle pulleies, 6.1 pulley bases, 6.2 jointed shafts, 7 girders, 8 auxiliary girders.
The specific embodiment:
Referring to Fig. 1, described hydraulic jack 1 is fixed on the sidewall of girder 7 or auxiliary girder 8, connects an end of pull rope 3 on the piston rod 2 of hydraulic jack 1; The sidewall of girder 7 or auxiliary girder 8 one ends is provided with angle pulley 6, and the other end of described pull rope 3 is walked around angle pulley 6 back coupling hooks 5; Described pull rope 3 is a wire rope; On described girder 7 or the auxiliary girder 8, be provided with draw ring 4; The pulley base 6.1 of described angle pulley 6 is fixed on girder 7 or the auxiliary girder 8, for making hydraulic pressure deviation correcting device force-bearing situation better, pulley base 6.1 can be hinged on girder 7 or the auxiliary girder 8 by jointed shaft 6.2, the rotational angle of hinged pulley base 6.1 should be not excessive, and its rotational angle should be limited in horizontal direction between downward 30 degree.
The power that the utility model uses the coal-face hydraulic system to provide, hydraulic jack is communicated with by the hydraulic pressure liquid-supplying system that valve, pressure hose and work plane are provided with.When tuningout, at first the piston rod 2 of hydraulic jack 1 is stretched out by injecting hydraulic oil (or emulsion), the hook 5 that connects pull rope 3 is suspended on the draw ring 4 of cantilever support back timber of temporary erection, the piston rod 2 of hydraulic jack 1 is regained in reverse then oiling (or emulsion), by tension pull rope 3, spur cantilever support, the deflection of cantilever support back timber is aligned fast.After tuningout finishes, hook 5 is hung on the draw ring 4 of this support, shrink piston rod 2 then with pull rope 3 tensions, the cantilever support deviation correcting device enters dormant state.
