Description
Technical field
The utility model relates to the big mining height hydraulic shield support that uses under the mine.
Background technology
Hydraulic shield support is the support apparatus of underground work indispensability.Along with improving constantly of down-hole mechanical extracting level, to the intensity of hydraulic shield support, highly, safety etc. requires more and more higher.Therefore, to combine the hydraulic shield support of adopting be the problem that those skilled in the art study always to the high-yield and high-efficiency that is used for that possesses that yield load is big, supporting height is high, supporting intensity is big.
The utility model content
The utility model purpose is to provide that a kind of yield load is big, supporting intensity and the high hydraulic shield support of support height.
For achieving the above object, the utility model can be taked following technical proposals:
Big mining height hydraulic shield support described in the utility model, it comprises base, is arranged on the Hydraulic Double telescopic column on the described base, described Hydraulic Double telescopic column top and set cap needling are hinged; Set cap rear portion and support caving shield are hinged; Support caving shield bottom is hinged by connecting rod and base; Described set cap is an overall structure, and the front portion is the drawer type extensible canopy, is hinged with the one-level face guard at described extensible canopy front end, is hinged with the secondary face guard at the front end of described one-level face guard, is hinged with the three-stage side protecting plate at the front end of described secondary face guard; Back timber is provided with flexible jack, and described flexible jack push rod is connected with extensible canopy is anterior; The extensible canopy front portion is provided with one-level wall supporting jack, and the push rod of described one-level wall supporting jack is hinged by little four bars and one-level face guard rear portion; The one-level face guard is provided with secondary wall supporting jack, and the push rod of described secondary wall supporting jack and secondary face guard rear portion are hinged; The secondary face guard is provided with the three-stage side protecting jack, and the push rod of described three-stage side protecting jack and three-stage side protecting postlaminar part are hinged; Between set cap and support caving shield, be provided with the balance jack that cylinder diameter is 280mm.
The length of set cap front and back ends is arrived than 2.35: 1 in the needling position that is arranged on the described set cap.
Described base is for opening mark structure in the middle of being rigidly connected.
The both sides side guard board of described set cap and support caving shield is bascule.
Described Hydraulic Double telescopic column is flexible highly to be seven meters, and its hydraulic cylinder cylinder diameter is Φ 500mm.
The utility model advantage is that working resistance of support is big, can reach more than the 16800KN, and supporting intensity reaches more than the 1.40MPa, is present tonnage the biggest in the world, the hydraulic support of maximum height; It is the hydraulic support that present in the world unique supporting height reaches 7m, the column application point is set to 2.35: 1 to back timber front end length and column application point to the top beam rear end length ratio, this ratio is 2.90: 1 after extensible canopy stretches out, when improving support front end support capacity, reduce base front end specific pressure.The effect of regulating support point of resultant force position, improving the Roof Control effect has been played in the setting of balance jack; When top board is more complete, when back timber rear portion pressure was big, balance jack was born pulling force, and will move behind the support force action position, increased the carrying of support rear portion and cut the top ability.Broken when top board, when the anterior pressure of back timber was big, balance jack was born pressure, and with the reach of support force action position, increased the anterior supporting capacity of support.For preventing roof cracking, coal wall caving problem, adopt the long side guard board structure of integral top beam, the back timber front end is provided with telescopic front-axle beam, realizes the timely maintenance control to anterior top board, prevents roof collapse.The extensible canopy front end is provided with three-stage side protecting mechanism, moves with extensible canopy, and the wall supporting height reaches 3.7m; In time the wall supporting jack is stretched out after coal-winning machine has been adopted coal, rib is lived in the face guard supporting, preventing coal wall caving, recoverable again face guard when trying to stop people from fighting each other, three grades protect nation can be folding fully, compact conformation.The connecting rod that support caving shield bottom and base are hinged adopts two front rods, whole back link structure, makes the support resistance to overturning good.Base adopts rigidity split pattern, and middle bay does not have base plate, and base gap bridge back is provided with lifts base mechanism, therefore helps float coal and discharges and lift base.
