Embodiment Construction
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] like figure 1 and figure 2 As shown, this embodiment includes copper backing boards 1, half clamps 2 and half trays 3 that are assembled in pairs. The copper backing boards 1 are bent into an arc shape smaller than a semicircle. The circle matches the outer circle of the piston rod 101 of the low-speed diesel engine. In this embodiment, the 2mm thick copper liner 1 is fixed on the inner circle of the half clamp 2 by riveting. When the half clamp 2 is clamped on the piston rod 101, the copper liner 1 can protect the outer circle of the piston rod 101 from Scratched by the inner side of a pair of clamp halves 2. The half-tray semi-circular hole on one side of the half-tray 3 matches the clamp semi-circular hole, the outer edges of the two ends of the half-clamp 2 respectively extend outward from the radial clamping plate 21, and the middle outer ...

The invention discloses an internal dismounting tool and method for a packing box of a piston rod of a marine low-speed diesel engine. The internal dismounting tool comprises a pair of copper liner plates which are assembled together, a pair of half clamping hoops which are assembled together, and a pair of half trays which are assembled together. The copper liner plates are fixed to the inner circles of the half clamping hoops. The half clamping hoops and ribbed plates at the outer ends of radial rods are fixed to the lower side faces of the half trays. The pair of half clamping hoops is clamped and fixed to the piston rod through clamping bolt and nut sets at the two ends of a radial clamping plate. The internal dismounting method comprises the steps that (1) the clamping hoops are primarily clamped and fixed to the piston rod; (2) the clamping hoops are lifted to be close to the lower side faces of a connecting flange and the packing box; (3) the packing box, the connecting flange and connecting bolts of the packing box are dismounted; (4) the tool is fixed to the lower side face of the packing box; (5) the piston rod is lowered to pull the packing box out; and (5) the packing box is dismounted after the bottom of a packing box shell is separated from the connecting flange. The internal dismounting tool is simple in structure, and the internal dismounting method is fast andconvenient to implement; and the packing box can be dismounted easily and effortlessly without a crane, the dismounting efficiency is improved, and the maintenance cost is reduced.
Description
technical field [0001] The invention relates to a special dismantling tool for maintenance of a marine low-speed diesel engine, in particular to a tool and method for dismantling a piston rod stuffing box of a marine low-speed diesel engine, belonging to the technical field of diesel engine maintenance. Background technique [0002] The crankcase and scavenging space of the marine low-speed diesel engine are separated and sealed by the piston rod stuffing box (hereinafter referred to as the stuffing box). Several oil scraping rings and sealing rings are installed in the stuffing box housing. Lubricating oil will not enter the scavenging space with the movement of the piston, and at the same time ensure that the gas in the scavenging space will not flow into the crankcase. It can be seen that the stuffing box is an important part to ensure the normal operation of the marine low-speed diesel engine. When the sealing effect of the stuffing box leaks and decreases during the ope...
