Abstract
The utility model relates to a lifting lug, in particular to the lifting lug of an engine. The lifting lug comprises a lifting hole positioned at the upper end of the lifting lug and an installing hole positioned below the lifting hole and used for connecting an engine cylinder cover, wherein the surface of the lifting lug, which is attached to the cylinder cover, is further provided with positioning bosses. By assembling the lifting lug on the engine, when the engine is lifted, as the positioning bosses are distributed on the lifting lug, the lifting lug can be effectively prevented from rotating around a bolt to be loosened, so that safe production is guaranteed; simultaneously, as only the single bolt is adopted for fixing, under the condition of meeting requirements, the assembling time of a production line is greatly shortened, and the production cost of an enterprise and the labor intensity of workers are reduced; in addition, when the engine is lifted, the positioning bosses can bear part of force, so that the bolt can be effectively prevented from breaking.
Description
Technical field
The utility model relates to the hanger of a kind of hanger, particularly a kind of driving engine.
Background technology
General hanger all is by being bolted on the cylinder cap, driving engine can being sling by hanger when driving engine need be sling.At present, most of driving engines all are to adopt single bolt hanger, though bolt has been screwed to the moment of regulation, when slinging driving engine, the device of slinging can make hanger produce side force, because the screw-down torque of bolt is less than the hanger side force, hanger can be the swing that basic point produces certain amplitude with the bolt, thereby makes bolt looseness, and the serious hanger that then may make comes off, cause industrial accident, influence enterprise security production.Two bolt hangers of the employing that also has come actv. to prevent that hanger from rotating around bolt, but owing to adopt two bolt, when assembling, have increased time of setting up on conveyor line, have increased working strength of workers, also are unfavorable for the reduction of enterprise's productive costs.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, hanger of being easy to assemble, can effectively avoid occurring between hanger, engine cylinder cover and tie bolt loosening and phenomenon that come off.
For achieving the above object, the utility model has adopted following technical scheme: a kind of hanger, comprise the lifting eye that is positioned at the hanger upper end and be positioned at the mounting hole that is used to be connected engine cylinder cover of lifting eye below, hanger with the cylinder cap bonding surfaces on also be provided with positioning convex.
The beneficial effects of the utility model are: at first, adopt single bolt, shortened the time of setting up of conveyor line greatly, reduced enterprise's productive costs and working strength of workers; Secondly, hanger is provided with positioning convex, and when slinging driving engine, hanger can not rotate around bolt, and then bolt can not become flexible, and can guarantee that the safety of driving engine is sling; At last, when slinging driving engine, positioning convex also can be shared a part of power, can prevent bolt fracture by actv..
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a scheme of installation of the present utility model.
The specific embodiment
A kind of hanger comprises lifting eye 11 that is positioned at hanger 10 upper ends and the mounting hole 12 that is used to be connected engine cylinder cover that is positioned at lifting eye 11 belows, hanger 10 with the cylinder cap bonding surfaces on also be provided with positioning convex 13.
Positioning convex 13 can be made as multiple shape, promptly reaches due locating effect as long as can satisfy its usage condition, and the selected scheme of the utility model is: positioning convex 13 profiles are cylindric, and described columned positioning convex 13 is locating dowel pin.Certainly, also can be set as detent with positioning convex 13 places are set, the cylinder cap groove of corresponding assembling be made as projection, also can reach corresponding locating effect.
Positioning convex 13 can be by several different methods machine-shaping, as welding, punching press etc.Scheme of the present utility model can be gone out positioning convex 13 in the lump for adopting impact forming method towards mounting hole the time, operation is simple and convenient, cost is also lower, like this, the thickness of hanger 10 should be more than or equal to 5mm, thereby the length of positioning convex 13 and intensity all can be guaranteed.Thickness as hanger 10 is too thin, and the positioning convex height that punching press is come out is lower, and not having to have positioning action, but if the thickness of hanger 10 is too thick, material has increased, and enterprise is productive costs and then increase.
Further, lifting eye 11, mounting hole 12 and registration device 13 are disposed in order from top to down in the ear length direction.
Further, positioning convex 13 be positioned at mounting hole 12 under.When lifting appliance was sling driving engine, this kind design can prevent the unbalance stress between bolt and the positioning convex 13, and hanger 10 is under the normal mode of operation all the time.
When during hanger 10, earlier the positioning convex on the hanger 10 13 being aligned in the knock hole of cylinder cap, and the mounting hole of hanger 10 aimed at the nut hole of cylinder cap in assembling, the bolt of screwing on, and be screwed to regulation moment.Since hanger 10 be by positioning convex 13 and bolt double fixed on cylinder cap, sling device when slinging driving engine by lifting eye 11, hanger 10 can not rotate around bolt, and then bolt can not become flexible, and engine health is sling.Simultaneously, when slinging driving engine, positioning convex 13 also can be shared a part of power, but actv. prevents bolt fracture.
