The invention discloses a brush holder structure of a large-scale low-speed DC lifting motor, and belongs to the field of motors. The brush holder structure comprises a positive conducting ring, a negative conducting ring and a circular brush holder base which are sequentially arranged at intervals from front to back along the axial direction, and is characterized in that the positive conducting ring is formed by butting two first semicircular bodies, the negative conducting ring is formed by butting two second semicircular bodies, the brush holder base is formed by butting two semicircular half brush holder bases, and the brush holder base is provided with positive electrode brush rod assemblies connected with the positive conducing ring and negative electrode brush rod assemblies connected with the negative conducting ring which are sequentially arranged at intervals in an alternative manner along the circumference. The brush holder structure of the large-scale low-speed DC lifting motor is reasonable in structure design, compact, reliable, convenient to assemble and disassemble, capable of being assembled or disassembled repeatedly, low in material cost, short in production cost, and capable of well meeting the operating requirements of disassembling and replacing a carbon brush and adjusting the center line of a brush holder.
