Detailed description of the invention
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, carry out knowing to the technical solution of the utility model and intactly describe, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See accompanying drawing, the utility model diesel-engine body bent axle cylinder sleeve chamber core hoisting appliance, mainly according to the constructional feature of body bent axle cylinder sleeve chamber core, utilize lever principle, find out the center of gravity of body bent axle cylinder sleeve chamber core, develop a kind of diesel-engine body bent axle cylinder sleeve chamber core special hoisting suspender.Diesel-engine body bent axle cylinder sleeve chamber sand core structure feature is: the crankshaft cavity being in bottom has one piece of smooth point core face, and be in the cylinder sleeve chamber on top in " V " font, Central Symmetry, designs this hoisting appliance according to this feature.Utilize the feature of symmetrical cylinder sleeve chamber in " V " font, the point of crossing of line of centers on crankshaft cavity smooth point of core face is got in center on cylinder sleeve, using the center of gravity of this point of crossing as core 9, on core box, two poles are designed based on this puts, form the upper tubing string lifting hole(eyelet) 10 of core 9 and lower tubular column lifting hole(eyelet) 11 thus, aperture 2mm larger than the diameter of upper tubing string 5 and lower tubular column 6.
By the top fold of the suspender main body 2 of tubulose, the plane that core 9 is walked around in bending position is in the middle of " V " type cylinder sleeve chamber of core 9, drop that is bending and plane is greater than a half thickness of core 9, the welded top of suspender main body 2 is fixed with the hanger 1 of annular, the bottom of suspender main body 2 is horizontal forward successively is from top to bottom welded with tubing string 5 and lower tubular column 6, distance between upper tubing string 5 and lower tubular column 6 is equal with the distance between the upper tubing string lifting hole(eyelet) 10 in the middle part of the crankshaft cavity of core 9 and lower tubular column lifting hole(eyelet) 11, upper tubing string 5 forms axis hole through suspender main body 2, the bull stick 3 of L shape passes the centre hole of upper tubing string 5 from the rear portion of suspender main body 2 and is fixed together with the biasing post 4 of outside, the diameter of biasing post 4 is consistent with the diameter of upper tubing string 5 and be inserted in upper tubing string lifting hole(eyelet) 10, lower tubular column 6 is inserted in lower tubular column lifting hole(eyelet) 11, biasing post 4 surface is threaded.When the outer bar of L shape bull stick 3 is with suspender main body 2 one-tenth 90 degree, the upper tubing string lifting hole(eyelet) 10 in the middle part of upper tubing string 5 and the concentric crankshaft cavity that can be inserted into core 9 of biasing post 4, lower tubular column 6 is inserted in lower tubular column lifting hole(eyelet) 11; When the outer bar of bull stick 3 is parallel with suspender main body 2 be close together time, the biasing post 4 in upper tubing string lifting hole(eyelet) 10 reaches eccentric maximum, eccentric 6mm.
In order to ensure rigidity, bending, by the large position of force intensity, welding auxiliary steel plate, ensure rigidity, increase safety, be welded with gusset 8 at the crooked position of suspender main body 2, the bottom tube wall of the suspender main body 2 of tubulose is fixed with strengthening steel slab 7.
The using method of the utility model diesel-engine body bent axle cylinder sleeve chamber core hoisting appliance is: by the outer bar of L shape bull stick 3 and suspender main body 2 one-tenth 90 degree, upper tubing string 5 is concentric and be inserted in the upper tubing string lifting hole(eyelet) 10 on diesel-engine body bent axle cylinder sleeve chamber core 9 with the biasing post 4 of its outside, lower tubular column 6 is inserted in lower tubular column lifting hole(eyelet) 11, rotate bull stick 3, biasing post 4 rotates thereupon, offset strengthens, when the outer bar of L shape bull stick 3 is parallel with suspender main body 2 close up time, now biasing post 4 reaches maximum offset, make tubing string 5 and lower tubular column 6 completely and core 9 tightly fixing, utilize the friction of biasing post 4 thread surface and sand, wipe unnecessary sand on tubing string lifting hole(eyelet) 10 off, prop up core 9.Re-use clamp the outer bar of L shape bull stick 3 and suspender main body 2 are fixed, crane trolley just can be used afterwards to hang up hanger 1, lift by crane and diesel-engine body bent axle cylinder sleeve chamber core 9 is erected.Bending position due to this hoisting appliance walks around the plane of core 9, in the middle of " V " the type cylinder sleeve chamber being in core 9, drop that is bending and plane is greater than a half thickness of core 9, after slinging, diesel-engine body bent axle cylinder sleeve chamber core 9 center of gravity tilts to suspender direction, difficult drop-off during handling, can safety be ensured, achieve steadily slinging and carrying of diesel-engine body bent axle cylinder sleeve chamber core.
Application the utility model diesel-engine body bent axle cylinder sleeve chamber core hoisting appliance, solve vertical core and the handling difficult problem of the core 9 such as 265 No. 8, diesel-engine body bent axle cylinder sleeve chamber cores 9,240V type serial diesel engine body 14#, ensure that the steady handling of diesel-engine body bent axle cylinder sleeve chamber core 9, its handling serviceability rate reaches 100%.In diesel-engine body bent axle cylinder sleeve chamber core 9 handling process, as long as one, ground operating personal, by the hanger 1 of this hoisting appliance on crane hook hook, slinging and carrying of diesel-engine body bent axle cylinder sleeve chamber core 9 just can be realized well.
The utility model diesel-engine body bent axle cylinder sleeve chamber core hoisting appliance is almost applicable to the lifting carrying of all similar diesel-engine body bent axle cylinder sleeve chamber cores 9, and the expense of whole suspender about about 200 yuan is economical and practical.
