Fire ring dismantling device of diesel engine cylinder sleeve

Abstract

The invention discloses a fire ring dismantling device of a diesel engine cylinder sleeve. The device comprises a dismantling cylinder, a cross support plate, a plurality of regulating bolts, a tension bowl, a positioning mechanism, a plurality of radial positioning bolts, a rotating rod and a hoisting shackle, wherein the cross support plate is fixed at the upper end of the dismantling cylinder,the outer end of the dismantling cylinder is respectively fixedly connected with a plurality of regulating nuts, the regulating screws are screwed on the regulating nuts; the radial outer edge of thetension bowl is fixed in the lower end of the dismantling cylinder, the inner side of the dismantling cylinder is radially fixedly provided with a plurality of nut seats, the dismantling cylinder is sleeved in a flame ring, the radial positioning screws pass through the nut seats, the end heads of the radial positioning screws extend into a flame ring positioning hole; and one outer end of the cross support plate is fixedly connected with the positioning mechanism, and the upper part of the cross support plate is respectively connected with the hoisting shackle and the rotating rod. The fire ring dismantling device has the advantages of simple structure and convenience for regulation, and overcomes the difficulty of dismantling the flame ring due to small space of a use occasion of a diesel engine, therefore, the dismantling efficiency is increased and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to a maintenance tool for a diesel engine, in particular to a device for dismantling a flame ring at the upper end of a cylinder liner, and belongs to the technical field of mechanical maintenance. Background technique [0002] The cylinder liner assembly of a high-power diesel engine generally includes a flame ring installed on the upper part of the cylinder liner. The flame ring is directly in contact with the high-temperature and high-pressure gas, and is easily damaged by the chemical corrosion of the high-temperature gas for a long time. When the flame ring is damaged, it only needs to be replaced directly instead of the whole Substantial maintenance costs can be saved by replacing the entire cylinder liner assembly. When removing the flame ring, maintenance personnel stand on the installation stool, use simple tools, and use the annular groove in the flame ring to disassemble and assemble the flame ring. This method of oper...

AI Technical Summary

Problems solved by technology

This method of operation requires a large operating space, it is difficult to use in a narrow place, and it is troublesome to adjust; the outer circle of the flame circle after burning is deformed, and it is tightly combined with the inner hole of the cylinder liner, and its lower end is embedded in the groove of the inner hole of the cylinder liner. In the groove, the two are closely combined, and a large pulling force is required to pull out the flame circle. This method of disassembling the flame circle cannot disassemble and assemble the flame circle of a large diesel engine with a large mass.
