Description
Technical field
The utility model belongs to underground coal mine support apparatus technical field, is related to a kind of for the advanced section reinforcement of stope drift active workings
The device of supporting, more particularly to a kind of back that can adapt to have greater obliquity, supporting area is big, occupies lane space
It is small, mobile stable, safe and reliable stope drift active workings lateral support formula advance support rack.
Background technology
During modern fully-mechanized mining, with the continuous propulsion of coal working face, the advanced section pressure of stope drift active workings
Power moves forward, therefore needs to carry out strengthening supporting in the advanced section of roadway workface.Lame advanced supporting is exactly in order to prevent by propping up in advance
Bearing capacity and the along inclined direction superposition of branch bearing capacity, caused deformation of the surrounding rock in tunnel and destruction, and the supporting used
Mode；And ensure the normal operation and ventilation of coal working face, avoid the generation of security incident.
Widely used coal working face lame advanced supporting, mostly using artificial hydraulic prop complexed metal hinged roof
The support pattern of beam or long girder steel.With the propulsion of coal working face, underground labour needs constantly to remove, branch individual prop；By
In the supporting complex procedures of individual prop, manual steps are more, and operating personnel's labor intensity is big, install, remove column and shifting
The speed of frame is slower, and the operation of the working face to roof cracking, prop drawing and recycling girder steel is more difficult, and security is poor；It is therefore difficult
To realize, significantly speed is promoted, and constrains the fltting speed of working face.For hydraulic prop complexed metal hinged roof
, has there are some advance supports for the advanced section supporting of roadway workface in limitation existing for beam progress lame advanced supporting
Stent.But the structure type that these advance support racks are supported mostly using the double hydraulic vertical prop in both sides, so it is accounted for
Space with tunnel both sides is more, can not adapt to the advance support that tunnel section is relatively narrow, equipment arranges more stope drift active workings and make
Industry；The arrangement form of its top beam, it is impossible to effectively adapt to the greater obliquity of back, and adapt to the ability of span length variation
Also it is poor.So being unfavorable for the supporting and management of top plate, safety, the high-yield and high-efficiency production of coal working face are influenced.
In addition, reported according to Patents documents, notification number be CN101832146B " large inclination working surface laterally anti-four connects
Bar advance timbering ", " forepoling with large inclination working surface and four transverse connecting rods " and publication No. that notification number is CN101852084B
For " guide rod type foresupport with large inclined angle working surface " of CN101787894A, smaller, nothing of all protecting top scope there are set cap
The local height that method adapts to back changes, and be easy to cause the problem of connecing unreal top, bad adaptability.The stabilization machine of these stents
Four-bar linkage structure occupied space is larger used by structure so that the range of stent is smaller, it is impossible to it is high to adapt to larger tunnel
Degree variation；And trail change during crane is big, stability deficiency.When stent is reduced using height, quadric chain can also
Limited pedestrian space is occupied, causes to pass through not smooth, practicability is very poor.
Therefore, to the further research of stope drift active workings advanced stand device, realize that the larger top plate of advanced stand device inclines
Angle adaptability expands supporting area, reduces occupied space, increases mobile stability, promote the security used, has weight
Want meaning.
