Description
Technical field
It is board-like flexible that the utility model is related to hydraulic pressure support equipment design fields more particularly to a kind of hydraulic support
Beam.
Background technology
Extensible canopy is arranged in top beam front end, and after coalcutter passes through, extensible canopy stretches out contact top plate in advance and plays gib
The effect of top plate bears horizontal component and lateral force that top plate gives, enhances the torsional property of holder, prevent beam-ends away from range
There is inbreak in advance in interior top plate, ensures beam-ends away from smaller, the maintenance work space of variation.Under normal circumstances, the structure of extensible canopy
Characterized by box-structure, right case is fixed on by the translation of extensible canopy intermediate channel inside top beam, is carried out by telescopic jack
Anterior-posterior translation moves, and structure is more complicated.
The top beam of hydraulic support directly and top plate contact, transmits support force and plays the bearing carrier of action retaining the top.Not unit-frame
The top beam of type has different characteristics.Monoblock type and section articulated can be divided by longitudinally connected mode, former structure is simple, end branch
Support force is big, easy to operate, but it is long when be unfavorable for connecing top and transport installation.Radial type top beam connects top preferably, is easily installed transport,
But front end supporting force is small, and structure is more complex.Radial type top beam includes main canopy, front-axle beam and back rest etc..Main canopy is also known as girder, i.e.,
Top beam above column.Front-axle beam is also known as forestope, is hinged on component of the supporting without column space top board in front of girder.Extensible canopy fills
Can be stretched out with forward slip in front-axle beam or girder, the component of gib working face fresh roof, can be divided into stretch formula and
Extending type.
According to the use environment of Bracket in Thin Coal Seam, when holder drops to extreme lower position, to prevent coal mining machine roller from cutting top
Beam ensures smoothly to mine simultaneously, under conditions of ensureing supporting intensity, it is contemplated that the safe spacing of coalcutter and holder, at this time again
Some problems will produce using box-structure, be complicated first, the movement of box-structure is comparatively relatively difficult, another
It is a precisely due to movement it is not rapid enough, it is bad to the effect of girdle, be unable to reach the purpose of supporting at any time, leverage work
Make efficiency, supporting effect is poor, therefore there is an urgent need for a kind of simple in structure, easy to use, good extensible canopies of supporting effect.
