The invention relates to the field of coal mine underground lifting equipment, and particularly relates to a mining hydraulic arm frame type lifting device. The mining hydraulic arm frame type lifting device is suitable for mounting of middle grooves of scraper conveyors with various models and the lifting weight within 5 tons. The device comprises a chassis, a rotating cylinder, an arm extending cylinder, a lifting cylinder, a lifting arm, a lifting arm lifting cylinder, a walking cylinder, a tensioning cylinder, a walking tensioning device, a middle tensioning device and a lifting tensioning device; the walking cylinder is horizontally mounted in the chassis; the walking tensioning device is arranged below the tail part of the chassis; the middle tensioning device is mounted on the side surface of the middle part of the chassis; one end of an outer arm of the lifting arm is connected with a rotating base; one end of an inner arm of the lifting arm is inserted in the other end of the outer arm; a lifting pulley is mounted at the other end of the inner arm; and one end of the lifting arm lifting cylinder is hinged with the outer arm, and the other end of the lifting arm lifting cylinder is hinged with the rotating base. The mining hydraulic arm frame type lifting device realizes directional walking of the whole hydraulic lifting device in the middle grooves, and finishes the mounting work of the middle grooves through the lifting tensioning device, the lifting cylinder and the lifting arm.
