Take brake mechanism's a hoisting accessory that moves

The utility model relates to a take brake mechanism's a hoisting accessory that moves, including moving platform, lifting machine constructs and brake mechanism, moving platform includes a fixed plate, the fixed sliding seat that sets up in fixed plate top, sliding seat upper end and track sliding connection, set up brake mechanism between arbitrary adjacent sliding seat, brake mechanism is including two butterfly brake blocks, set up a fixed block between the two, two butterfly brake blocks rotate with the fixed block to be connected, fixed block lower extreme and fixed plate fixed connection, the lower extreme of two butterfly brake blocks is articulated with hydraulic jack, the upper end of two butterfly brake blocks sets up the fixture block, realization braking on the track is huggedclosely through hydraulic jack's flexible its degree of opening and shutting of change and then drive fixture block to two butterfly brake blocks, move a hoisting accessory through setting up that moving platform, lifting mac
