Description
Technical field
Present invention relates particularly to facility of mining, specially a kind of interim easy hydraulic support.
Background technology
The demand of coal in China is increasing, and corresponding coal mining is also more next big.Big inclined low seam reserves account for China
The 8% of coal gross reserves, particularly in southwestern section, 80% mining area preservation has big inclined seam.For a long time, such coal seam
Exploitation it is extremely difficult, efficiency is low, cost is high, and safe pressure is very big.Traditionally the supporting to ultra-thin coal seam typically uses mine timber
Two kinds of forms of supporting or individual prop supporting, but both support patterns are all present that labor intensity is big, supporting intensity is low, safety
Situation is poor, the low defect of efficiency.
In recent years, with the development of coal-mining technique, fully mechanized mining and top grade are also used in the deep inclined thin coal seam of some mines
It is general to adopt technology.But due to coal seam feature, in the traction of coal-winning machine, the installation of support, regulation, propulsion aspect are very difficult, make
High into cost of winning, labor intensity is big.Therefore for the exploitation of deep inclined thin coal seam, it is badly in need of a kind of new support equipment to solve
Certainly problems faced.
Patent (201620006696.3) discloses a kind of adjustable flexibility support, and it cranks arm by hinge including two up and down
Connection, the technology of hydraulic cylinder is then set at middle part, well can be minimized falsework, is adapted to scope extensively, can be free
Stretch, in especially suitable small space.But, a kind of this kind of adjustable flexibility support is adjustable mainly to pass through coal mining space
Mining height regulation bearing height (being adjusted by the height for adjusting hydraulic support), but during coal mining, due to seam inclination
Difference, designed coal mining space is also changed, and the angle of the rib and top plate, bottom plate in coal seam can also change, required branch
Above and below frame two crank arm between angle also produce change.And a kind of adjustable flexibility support of patent (201620006696.3) can not
Meet this requirement.Meanwhile, if the area of coal-face support produces change, baseplate width increase, top plate width increase,
Requiring the Area of bearing of hydraulic support will also increase, and a kind of adjustable flexibility support of patent (201620006696.3) can not expire
This requirement of foot.Meanwhile, existing flexible type shield also has the disadvantage that：
Mining height is fixed：Existing flexible type shield is the I-beam for mine of certain model by being bent into " splayed ", " 7 words
Type ", once bending after shaping, can only adapt to fix the working face of mining height, bad adaptability.
Stress is poor：Existing flexible type shield uses " splayed " mostly in use, existing by carefully analyzing
It is poor that flexible type shield bears roof pressure, support beam and caving shield Integral design on existing flexible support, be global facility or
Person's fixedly connected part, because mining height is excessive, shielding beam stress is increased, and just caving shield material, material must be strengthened, structure is more multiple
It is miscellaneous,
In-convenience in use, quality is larger：For high working face coal seam, caving shield, top bottom girder stress are increased, and must just be increased and be covered
Guard beam, the material thickness for pushing up bottom girder, increase weight, and the installation, belt removal to working face come very big inconvenient.
Therefore, under the conditions of complicated coal-face, it would be desirable to which one kind adapts to wider array of coal-face support liquid
Press support.
The content of the invention
In order to solve the above problems, it is an object of the invention to the shortcoming for overcoming prior art, there is provided a kind of rod hinge connection
The scalable flexible hydraulic shield support of type, its support force is bigger, using more flexible, and adaptability is wider.
The scalable flexible hydraulic shield support of rod hinge connection type of the present invention, by upper support beam 1, bottom beam 3, jack 4

Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described corresponding accompanying drawing.
It is of the invention to be made up of upper support beam 1, caving shield 2, bottom beam 3, jack 4, connecting rod with reference to Fig. 1, upper support
Beam, caving shield, bottom beam are engaged by hinge head and the tail series winding, and each can mutually free deflection, and mutually constitute angle, thousand
Jin top is arranged in the angle that support beam, caving shield, bottom beam are constituted with connecting rod.The two ends of connecting rod are movably connected in support
On beam, caving shield.Connecting rod is divided into two sections, and connecting rod first paragraph 5 is connected with connecting rod second segment 6 by connecting rod link；Jack tail end
It is arranged in bottom beam, the top of jack is connected on connecting rod.
Each connecting portion of the present invention is that articulate is connected, including the string between upper support beam, caving shield, bottom beam
Connect；Installation of the connecting rod on upper support beam, caving shield；The top of jack, the installation of the tail end of jack, are articulate
Connection.The apical support of jack is on connecting rod link.
Support beam length is that 1300mm, shielding beam length are that 1200mm, bottom beam length are 1100mm.Connecting rod is first section long
Spend for 1000mm；The segment length of connecting rod second is 25mm.Connecting rod first paragraph be connected to support beam front portion and away from upper support beam before
Hold at 450mm；The tail end of jack be connected in bottom beam and away from bottom tail beam 300mm at.
In upper support beam 1 foremost, and caving shield middle part and bottom, and the caudal end of bottom beam 3 is respectively provided with
There is steel hinge line installation clip 7.
In use, the present invention is arranged on coal-face, and goaf is supported, with to coal-face
Protected, and pushed ahead with the propulsion of coal-face.In coal-face, some rod hinge connection types of the invention
Scalable flexible hydraulic shield support accommodated side-by-side, and be attached each shield support using steel hinge line, steel hinge line is just stuck in
In steel hinge line installation clip 7.The upper support beam of the present invention connects top coal-face top plate, and caving shield stops to be caving from goaf
Spoil, bottom beam is placed on coal-face bottom plate.
