Abstract
The invention discloses a large marine low speed diesel engine piston fixing tool which is characterized in that a spacer sleeve is vertically arranged, a cantilever is fixedly connected at the bottom of the spacer sleeve, and a C-shaped plate is suspended at the front end of the cantilever. A cylinder body fixing bolt capable of fixing the spacer washer on a cylinder body is arranged on a spacer sleeve bolt hole which is arranged at the rear end of the cantilever and penetrates through the cantilever and the spacer sleeve. Piston base fixing bolts capable of fixing the C-shaped plate on a piston base are arranged in C-shaped plate bolt holes which are arranged at two ends of the C-shaped plate and penetrate through the C-shaped plate. The large ship low speed diesel engine piston fixing tool can conveniently and safely fix piston when a large marine low speed diesel engine is assembled and dispatched.
Description
Technical field
The present invention relates to a kind of instrument, say that more specifically the piston assembly with marine low speed diesel engine is fixedly attached to the setting tool that uses on cylinder block.
Background technique
Large-scale marine low speed diesel engine need to be fixed on piston on cylinder body when assembling and shipping safely, but the existing setting tool dismounting difficulty of using, operation is inconvenience very; Some setting tools can because of structural imperfection, still have potential safety hazard.
Summary of the invention
The present invention is for avoiding the existing deficiency of above-mentioned prior art, a kind of piston setting tool is provided, so that large-scale marine low speed diesel engine is convenient when machine is torn in assembling and shipping open, fixed piston safely, facilitates the workman to operate, and increases work efficiency.
The present invention is that the technical solution problem adopts following technological scheme:
The structural feature of the large-scale marine low speed diesel engine piston of the present invention setting tool is: be spacer sleeve vertically is set, connect firmly cantilever in the bottom of described spacer sleeve, articulate " C " template at the front end of described cantilever; The rear end of described cantilever and run through cantilever and spacer sleeve on the spacer sleeve bolt hole, be provided with the cylinder body fixing bolt that spacer sleeve can be fixed on cylinder body; " C " template bolt hole that runs through respectively at the two ends of described " C " template on " C " template is provided with the piston base fixing bolt that described " C " template can be fixed on piston base.
The structural feature of the large-scale marine low speed diesel engine piston of the present invention setting tool also is: described cylinder body fixing bolt is in the spacer sleeve bolt hole, and described piston base fixing bolt all has the activity surplus in described " C " template bolt hole.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, volume of the present invention is little, and is lightweight, safe and reliable, is very easy to workman's operation, improved working efficiency;
2, the present invention has solved marine low speed diesel engine effectively when shipping decomposition gas cylinder body and frame, and the interference problem that exists when the fixed piston assembly is installed: the one, jiggering is to when top dead center, be that piston assembly moves to when peak, the skirt body of stuffing box may be collided with the piston setting tool, and the spacer sleeve in the present invention has been avoided this interference well; The 2nd, jiggering is during soon to top dead center, and the cross head bearing lid may be collided with the piston setting tool, and the cantilever in the present invention has been avoided this interference well.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention uses view;
Number in the figure: 1 spacer sleeve; 2 cantilevers; 3 is " C " template; 4 cylinder body fixing bolts; 5 piston base fixing bolts; 6 stuffing boxes; 7 cylinder bodies; 8 piston setting tools; 9 cross head bearing lids; 10 diesel engine pistons.
Embodiment
Referring to Fig. 1, Fig. 2, the structure setting of the medium-and-large-sized marine low speed diesel engine piston of the present embodiment setting tool is:
Be spacer sleeve 1 vertically is set, connect firmly cantilever 2 in the bottom of spacer sleeve 1, articulate " C " template 3 at the front end of cantilever 2;
As shown in Figure 1, in order to implement to fix, in the rear end of cantilever 2, run through the spacer sleeve bolt hole on cantilever 2 and spacer sleeve 1, be provided with the cylinder body fixing bolt 4 that spacer sleeve can be fixed on cylinder body; " C " template bolt hole that runs through respectively at the two ends of " C " template 3 on " C " template 3 is provided with the piston base fixing bolt 5 that " C " template 3 can be fixed on piston base.
In concrete enforcement, cylinder body fixing bolt 4 is in the spacer sleeve bolt hole, and the piston base fixing bolt all has the activity surplus at " C " template bolt hole, adjusts in right amount on the diesel engine fore-and-aft direction when installing.
in use, the piston of fixing a cylinder need to be with the piston setting tool 8 in two the present embodiment, at first will connect diesel engine piston 10 and pull down with four bolts of diesel engine connecting bar crosshead pin, then with M20 cylinder body fixing bolt 4, piston setting tool 8 will be tightened on cylinder body 7, then carry out jiggering, namely diesel engine piston 10 is advanced to peak, when fast when coiling to top dead center, again lentamente to peak promotion diesel engine piston 10, make the upper plane of base of diesel engine piston 10 lentamente near the lower plane of " C " template 3 of piston setting tool 8, when plane on piston base just touches the lower plane of " C " template 3, stop at once promotion diesel engine piston 10, at this moment the piston base fixing bolt 5 of four M16 is screwed into respectively on piston base in four corresponding tapped holes, diesel engine piston is connected together with piston setting tool 8.
