An energy-saving and environment-friendly bolt punching device with precise positioning and its operation method

Abstract

The invention discloses an energy-saving environment-friendly bolt punch device precise in positioning and an operation method thereof. The device comprises a moving support and a bolt punch, a firstmotor is longitudinally arranged below the moving support, the upper portion of the first motor is rotatably connected with a rotating rod, and a horizontal lifting appliance is vertically arranged above the rotating rod. The device has the beneficial effects that a hydraulic cylinder body in the bolt punch drives a drill rod to rush out outwards through a piston rod, the impact force of the drillrod to the bolt can be improved, the dismounting efficiency of the bolt on a lining plate by a worker can be improved, a front damping pad on the bolt punch carries out supporting and sleeving on thedrill rod, punch losses of the drill rod and other parts on the bolt punch can be reduced, and a hydraulic system on the bolt punch is small in heating, low in noise, and energy-saving and environment-friendly in use. A power system on the bolt punch device is driven through a motor, emissions of harmful gas do not exist, use environment friendliness is ensured, the bolt punch device is providedwith the horizontal lifting appliance and a vertical lifting appliance, and through the auxiliary effect of a guide sleeve, horizontal and vertical bolts can be smoothly dismounted.

Description

technical field [0001] The invention relates to a bolt punching device, in particular to an energy-saving and environment-friendly bolt punching device with precise positioning and an operation method thereof, belonging to the technical field of bolt punching devices. Background technique [0002] With the continuous improvement and enlargement of mining equipment, the automation of the removal of the internal liner bolts of large mills has also been continuously improved. At present, when domestic enterprises replace the liner of the ball mill, most of the liner bolts are removed by manual impact, resulting in The work efficiency is low, the labor intensity is high, and the potential safety hazard is large. At the same time, it takes up a lot of maintenance space, the technology is backward, and the replacement cost is high. It is a very time-consuming and labor-intensive task, and the dismantling of a medium-sized mill can take as short as one month and as long as 2 months...
