Abstract

The utility model discloses a hydraulic shield support, which comprises a base and a hydraulic extension column. The top end of the hydraulic extension column is pivoted with a support roof beam castle; the rear part of the support roof beam is of the whole structure, which is provided with an extension beam at the front end; a first level lasting protecting plate is hinged at front end of the extension beam, which is pivoted with a second level lasting protecting plate at front end; the extension beam is arranged with a first level lasting protecting jack whose top poleis hinged with the rear part of the first level lasting protecting plate; a second level lasting protecting jack is arranged on the first level lasting protecting plate, whose top pole is hinged with the rear part of the second level lasting protecting plate; a balancing jack is positioned between the support roof beam and the support shield beam. The utility model has the advantages of large working resistance of the supporting achieving over 9400 KN and the supporting intensity over 1.08 MPa.

Description

Hydraulic shield support
Technical field
The utility model relates to the 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, possess that yield load is big, high trestle, hydraulic shield support that supporting intensity is high be the problem that those skilled in the art study always.
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:
Hydraulic shield support described in the utility model, it comprises base, is arranged on the hydraulically extensible column on the described base, described hydraulically extensible 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, is provided with extensible canopy in its front end body; Be hinged with the one-level face guard at described extensible canopy front end, be hinged with the secondary face guard at the front end of described one-level face guard; Extensible canopy is provided with one-level wall supporting jack, and the push rod of described one-level wall supporting jack and one-level face guard rear portion are hinged; 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; Between set cap and support caving shield, be provided with balance jack; Be arranged on the connecting rod that support caving shield bottom and base be hinged and be two front rods, whole back link structure.
The length of set cap front and back ends is arrived than 2.43: 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.
Two side guard boards of described set cap and support caving shield are respectively the fixedly movable setting of opposite side of a side.
The utility model advantage is that working resistance of support is big, can reach more than the 9400KN, and supporting intensity reaches more than the 1.08MPa, and support height can reach 6.2 meters.The column application point is set to 2.43: 1 to back timber front end length and column application point to the top beam rear end length ratio, when improving support front end support capacity, reduces 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 solving roof cracking, coal wall caving problem, adopt extensible canopy and long side guard board structure in the integral top beam front end band, realize timely control to breaking roof, prevent roof collapse.Extensible canopy is provided with little four bar side protecting mechanisms, and the two-stage wall supporting is the radial type structure, in time the wall supporting jack is stretched out after coal-winning machine has been adopted coal, and rib is lived in the face guard supporting, to prevent coal wall caving, recoverable again face guard when trying to stop people from fighting each other, 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, therefore helps the float coal discharge and lifts base, and be provided with accent frame jack position, realizes transferring holder function.This support height is to break through the 6m maximum height in the world at present to have reached 6.2m, the bracket upright post cylinder diameter reaches Φ 380mm, be domestic complete first use, working resistance reaches more than the 9400KN, adopt integral top beam band extensible canopy, and the extensible canopy front end is with the high secondary side protecting mechanism of 2.6m again, and completely normally uses at mining face under mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, hydraulic shield support described in the utility model comprises base 1, is arranged on the hydraulically extensible column 2 on the described base 1, and the needling 4 on described hydraulically extensible column 2 tops and the set cap 3 is hinged; Set cap 3 rear portions and support caving shield 5 are hinged; Support caving shield 5 bottoms are hinged by connecting rod and base 1; Described set cap 3 is an overall structure, is provided with extensible canopy 6 in its front end body; Be hinged with one-level face guard 7 at described extensible canopy 6 front ends, be hinged with secondary face guard 8 at the front end of described one-level face guard 7; Extensible canopy 6 is provided with one-level wall supporting jack 9, and the push rod of described one-level wall supporting jack 9 and one-level face guard 7 rear portions are hinged; One-level face guard 7 is provided with secondary wall supporting jack 10, and the push rod of described secondary wall supporting jack 10 and secondary face guard 8 rear portions are hinged; Between set cap 3 and support caving shield 5, be provided with balance jack 11; Be arranged on the connecting rod that support caving shield 5 bottoms and base 1 be hinged and be two front rods 12, whole back link 13 structures.The length of set cap 3 front and back ends is arrived than 2.43: 1 in needling 4 positions that are arranged on the set cap 3; Base 1 is for opening mark structure in the middle of being rigidly connected; Two side guard boards 14,15 of set cap 3 and support caving shield 5 are respectively the fixedly movable setting of opposite side of a side.
