Two. the filling template of the filling template supporting type cantilever support that the utility model provides comprises the push mechanism that extensible member that framework, one end are fixedly connected with framework and one end are fixedly connected with framework, the free end of described extensible member is connected with the free end of push mechanism, and push mechanism can drive extensible member to stretch or shrink, make filling template to adjust at any time its extension distance according to goaf height or face width, make the filling template supporting type cantilever support that the utility model provides there is good compliance;

Three. the extensible member in filling template is chimeric box, described chimeric box comprises outer case and internal box, the external dimensions of internal box and the inside dimension of outer case are in full accord, internal box can slide in the inside of outer case, makes filling template can have enough intensity to meet the requirement of supporting;

Four. the push mechanism in filling template is the second hydraulic jack, can in the time of supporting, provide enough strong support force, also makes easy and simple to handle;

Five. be provided with sealing block at the free end of extensible member and the free end connection of push mechanism, described sealing block is fixedly fitted in extensible member free end and the free-ended end of push mechanism, can effectively adjust according to the smooth situation on ground, to reach the concrete effect of sealing.

In a word, the filling template supporting type cantilever support that the utility model provides can guarantee the seal request to inserts in the time of filling, can guarantee again the supporting requirement in goaf, has rational in infrastructure, easy to use, in the time that being carried out to inserts, goaf there is supporting and template function.
