Special tool for restoring seat hole of machine of haven

Abstract

The invention relates to a special tool for restoring a seat hole of a machine of a haven, which is provided with a bend angle base, wherein a dovetail slide way seat of a machine tool is arranged on the bend angle base, a slide plate with a dovetail groove is arranged on a dovetail slide way on the dovetail slide way seat, a rotatable lead screw is arranged on the dovetail slide way seat which is matched with a screw sleeve below the slide plate, a motor with a speed reducer is arranged above the slide plate, an output shaft of the speed reducer is connected with a cardan shaft mechanism, the other end of the cardan shaft mechanism is connected with a long toolbar, and two adjusting racks are matched on the long toolbar. The invention has the effects that the special tool for restoring the seat hole of the machine of the haven is adopted to maintain the shaft hole of the large-sized loading and unloading equipment of the haven, such as the equipment of a portal hoist, a large-sized crane and the like, can carry out in-situ operation, does not need to completely disassemble the equipment, can carry out in-situ maintenance, is convenient to use, saves the time of disassembly, lifting and transportation and shortens the maintenance period. The expansion and contraction length of a cutter can be adjusted by using an adjusting bolt, and the use is convenient and accurate. The long toolbar can be superposed with the center of the seat hole to be processed by adjusting the bolts via the adjusting racks.

Description

technical field [0001] The invention belongs to mechanical repair tools, in particular to a special tool for repairing seat holes of port machinery. Background technique [0002] At present, there are many large-scale machinery in the port and wharf, so the repair work has increased accordingly. The shafts and hole matching parts of many large-scale port machinery and equipment are often worn, and the machinery is large and difficult to disassemble. Since the company's loading and unloading goods are mainly imported mineral powder, the utilization rate of port machinery is maintained at about 70%, and the operation is frequent. This high-intensity use causes the connection seat holes of various parts of the machinery to lose their garden and deform, especially the bucket and waist shaft. Seat holes generally need to be repaired. In the past, the outsourced maintenance method was adopted. After the large parts were disassembled, the repaired parts were pulled to the workshop...

The shafts and hole matching parts of many large-scale port machinery and equipment are often worn, and the machinery is large and difficult to disassemble

Since the company's loading and unloading goods are mainly imported mineral powder, the utilization rate of port machinery is maintained at about 70%, and the operation is frequent. This high-intensity use causes the connection seat holes of various parts of the machinery to lose their garden and deform, especially the bucket and waist shaft. Seat holes generally need to be repaired. In the past, the outsourced maintenance method was adopted. After the large parts were disassembled, the repaired parts were pulled to the workshop of the maintenance unit for maintenance work. The disassembly required the cooperation of a large crane. Time, not only the maintenance cost is extremely high and the maintenance cycle is long, which affects the efficiency of port operations. It costs about 12,000 yuan to repair each pair of seat holes, and more than ten times a year, which brings considerable cost pressure to the enterprise.
