Abstract

The invention relates to a mechanical arm device for replacing a lining board of a ball mill. In order to solve the problems that domestic equipment for replacing the lining board of the ball mill is obsolete, a great deal of labor power is required, a working environment is unsafe, and cost for importing overseas equipment is high, the invention provides the mechanical arm device for replacing the lining board of the ball mill. The mechanical arm device comprises a rotary supporting mechanism, a suspension arm lifting mechanism, a suspension arm telescoping mechanism, a wrist mechanism and a clamping device, wherein the rotary supporting mechanism is connected to the suspension arm telescoping mechanism; the two ends of the suspension arm lifting mechanism are separately connected to the rotary supporting mechanism and the suspension arm telescoping mechanism; the suspension arm telescoping mechanism is connected to the wrist mechanism; and the wrist mechanism is connected to the clamping device. The mechanical arm device has the beneficial effect of realizing multi-degree of freedom, so that a mechanical arm can enter the barrel body of the ball mill very well for mounting and replacing the lining board; and except that the rotary supporting mechanism is driven by a servo motor, the rest of the mechanisms and the clamping device are driven by hydraulic cylinders, so that the manufacturing cost is greatly reduced and the operation controllability is strong, and therefore, the mechanical arm device is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of ball mills, and in particular relates to a ball mill liner changing mechanical arm device. Background technique [0002] The liner of the ball mill is used to protect the cylinder of the ball mill from the direct impact and friction of the grinding body and the material. At the same time, different forms of liners can be used to adjust the movement state of the grinding body to enhance the crushing of the material by the grinding body It helps to improve the grinding efficiency of the mill, increase the output and reduce the metal consumption. At present, domestic ball mill liner replacement equipment is backward, and a device similar to a truck-mounted crane is used, which is composed of a telescopic arm, a slewing support and a winch. To the hoisting position, the liner is hoisted and then manually pushed to the exact installation position. Due to the large and numerous liners inside the ball mill, it...
