In " the ┌ ┐ " of balance arm casing frame branch open side, be positioned at its biside plate and be provided with spacing gib block; Distance between these two spacing gib block medial surfaces is less than the width of float extension beam; The float extension beam support on these two spacing gib blocks and and these two spacing gib blocks between constitute sliding pair along its length direction; In " the ┌ ┐ " of float extension beam open side, be positioned at its biside plate and be provided with the second spacing gib block; Distance between these two second spacing gib block medial surfaces is less than the width of extensible canopy casing frame branch, extensible canopy casing frame branch be supported on these two second spacing gib blocks and and these two second spacing gib blocks between constitute sliding pair along its length direction.
At float extension beam front end, it is positioned at former and later two sides and respectively is provided with a front end limited block, respectively is provided with a rear end limited block in extensible canopy front end, former and later two sides of being positioned at its two casing frame branches.
In the rear end of the front end of balance arm and extensible canopy, be positioned at its casing frame branch and respectively be provided with a hinged ear of jack, the two ends of flexible jack are articulated on the hinged ear of jack of rear end of front end and extensible canopy of balance arm.
Said balance arm adopts by the steel plate welding and forms, and said float extension beam is formed by the steel plate welding, and said extensible canopy is formed by the steel plate welding.
The utility model is compared with prior art, and its effect is actively with tangible.Originally the containment type waste filling ramming mechanism that is used for the waste filling hydraulic support just spoil is filled ramming mechanism and is designed to the casing subsumption architecture; Balance arm and extensible canopy adopt standard-sized sheet crotch structure; Independent jack is placed in one in its each branch, and has enough space to leak cash between crotch, its objective is that foreign material such as avoiding coal ash and spoil bleed in the ramming mechanism; Increase magnification; Enlarge filling scope and tamping ability as far as possible, its abundant tamping is filled, avoided the phenomenon that also can occur caving in after the former tamping as far as possible.
