The invention relates to a hydraulic bracket assembling and disassembling
machine with supporting upright columns, which belongs to the technical field of equipment for disassembling a hydraulic bracket on a
coal mine fully-mechanized working surface, provides an assembling and disassembling
machine which can conveniently move and assist to disassemble and transport the hydraulic bracket, and adopts the scheme that a rotating plate is installed on a vehicle body, the outer end of the rotating plate is articulated with a lifting plate, the cylinder body of an angle-modulated oil cylinder is installed at the lower part of the outer end of the rotating plate, a
piston rod end head is connected with the lower part of the lifting plate, the cylinder body of a rotary oil cylinder is installed at the lower part of the vehicle body, the
piston rod end of the rotary oil cylinder is movably connected with one end of a
crank, the other end of the
crank is fixed at the middle position of the bottom of the rotating plate, two supporting upright columns are together vertically installed at one side of the vehicle body, a supporting oil cylinder is respectively installed at both ends of the two supporting upright columns, and a
pulley is installed on the vehicle body between the two supporting upright columns; and the invention is applied to the technical field of mine vehicles.
