Description
Technical field
The present invention relates to fully-mechanized mining working air return lane advanced hydraulic supports, are especially for the big work resistance of air return lane
Power advanced hydraulic support.
Background technology
Downhole crossheading tunnel is to modernize fully-mechanized mining working important material transportation and underground ventilating channel.Due to underground
Complex geologic conditions, terrane stress distribution are difficult to accurately calculate, and cause back deformation, roadway's sides into contract extruding
Prominent 14,15 phenomenon of pucking occurs（As shown in Figure 6）, personnel and equipment safety are directly affected, therefore the supporting of gate road is very heavy
It wants.To solve above-mentioned roadway support issues, advanced hydraulic support is mostly used at present and carries out mechanization supporting.
In recent years, in the coal production practice for being easy to happen Floor Heave in Roadway, the lane of first advance 30~50m ranges
Road, top plate is under the conditions of original bolting and rope support, and using advance timbering supporting, top plate can be safeguarded substantially, but there is also
Following problem：1, supporting intensity is low：Existing excavation support generally uses 230mm~320mm columns, according to excavation support top beam
The areal calculation supporting intensity that contacts back is general≤1.2MPa, if but according to tunneling boring in supporting region（Supporting
Tunnel length × span length）It calculates, the supporting intensity of existing advance timbering is difficult more than 1Mpa；2, device security is insufficient：
It dashes forward in the extruding of roadway's sides, will squeeze support apparatus causes column to damage；3, the generation of pucking can not effectively be prevented：Advanced branch
The generation fierceness in the place that frame pedestal does not cover, pucking greatly increases；4, personnel traffic areas and airspace cannot be protected
Barrier：Serious pucking protrusion can reach 1 meter or more, and walkway and airspace will be caused even to be lost by compression；5, equipment
The traffic capacity is limited：For pucking once occurring, the spoil that roadway floor is filled with causes advance timbering can not be to reach frame, significantly at once
Affect the propulsion normally produced.
Invention content
Present invention aims at providing, a kind of supporting intensity is high, ensure walkway and section of divulging information is safe and reliable is used for
The big working resistance advanced hydraulic support of air return lane.
To achieve the above object, the present invention takes following technical proposals：
Big working resistance advanced hydraulic support of the present invention for air return lane includes two supporting lists of spacing side by side setting
Member, the supporting cellular construction described in two is identical, is made of longitudinally disposed fore-stock and after-poppet；The fore-stock and
It is hinged by advancing jack between after-poppet；Fore-stock is identical with after-poppet structure, by top beam, caving shield, double leval jib
Mechanism, pedestal, telescopic column, inside bottom tune jack, outside bottom tune jack composition；It is located at the caving shield on the pedestal
It is forward and backward be respectively provided with two telescopic columns, the bottom and top of each telescopic column respectively by needling with
Pedestal and the top beam are hinged；Box pedal channel is vertically arranged on the inside of pedestal, the inside bottom tune jack is along horizontal
To being arranged in the box pedal channel interior, the outside bottom tune jack is transversely arranged in chassis interior；Outside top beam
It is hinged with waste rock board under lateral, lower waster rock blocking plate has been hinged up on the outside of pedestal, the upper and lower waste rock board mutually overlaps.
The inside bottom tune jack of the box pedal channel interior is two of longitudinally spaced setting；In the pedestal
The outside bottom tune jack in portion is two of longitudinally spaced setting.
It is hinged by the connection frame jack being arranged on the top beam between two supporting units arranged side by side.
Box pedal channel upper surface is provided with anti-skid chequer.
Advantage of the present invention embodies in the following areas：
1, two supporting units are configured with eight large-diameter telescopic columns, it is achieved that big working resistance and supporting intensity；
2, safety has been reserved in longitudinally disposed box pedal channel on the inside of the pedestal of two supporting units for people's row and transport material
Space；
3, the top beam outside of two supporting units and chassis outer side have been respectively articulated with waste rock board and lower waster rock blocking plate, realize equipment
People's row region is isolated with roadway's sides, avoids roadway's sides and occurs to squeeze the interior prominent damage for leading to support apparatus；
4, the outside bottom tune jack of inside bottom tune jack and chassis interior in box pedal channel interior is set so that when
It, can be by adjust the distance between two supporting units, the pedestal of two supporting units being bonded, is avoided when pucking occurs
Pucking in turn ensures the spatial channel of pedestrian and ventilation；
5, be hinged by advancing jack between the forward and backward holder of each supporting unit, formed it is powerful from shifting ability, even if
There is portion support outside two to help extruding coal cinder and pucking spoil crowded in holder front, can also rely on advancing jack and lead to by force
It crosses, ensure that the normal production of fully-mechanized mining working promotes.
