Abstract
The utility model relates to a hoisting chain of a hoister. A common outer link plate of an existing hoisting chain is a conventional plate structure, the integral chain cannot be uniformly stressed due to technical errors, the link plate and a hinge pin are stressed on the same point in a centralized manner, quick friction is generated, gaps are enlarged, the chain is easy to shake and accordingly is broken, and the service life of the chain is shortened. The hoisting chain of the hoister comprises an inner link plate, an outer link plate, a rolling sleeve pin and a rivet, and is characterized in that the outer link plate consists of a bottom plate connected with the inner link plate by the rivet, and externally folded plates are formed on two sides of the bottom plate. The shape of the outer link plate is changed, the contact area of the outer link plate and a hopper is reduced, and various portions of the chain are stressed uniformly. Besides, gaps among a hinge pin and the link plates are increased, and shaking can be effectively relieved. Besides, the hoisting chain is good in operational stability and long in service life.
Description
Technical field
The utility model relates to the important driving component in the Ne series lift, especially a kind of lift lift chain.
Background technique
NE series lift chain is a most important driving component in the NE series lift, mainly contains strand formula and double-chain two kinds.Generally form by roller, sleeve, bearing pin, outer plate, inner plate, rivet.Can also add other accessories, in NE series lift, the outer plate and the hopper of chain are used bolt, and general per two pitch chain bars connect a hopper.During the lift operation, chain will support the power of all stacks of magazines fulls with substance.So it also is the easily damaged parts of easy abrasion.Present outer plate a kind of slab construction of routine normally, such flat board is fixed on the hopper, because technology exists error to make the whole chain can not be evenly stressed easily; It is stressed to cause carrier bar and bearing pin on a point, to be concentrated; Produce friction fast, cause the gap to be amplified, chain is prone to produce shaking phenomenon; Cause chain rupture to occur, finally reduced the working life of chain.
Summary of the invention
The utility model provides a kind of lift lift chain to the problem that existing technology exists, and can effectively alleviate the shaking phenomenon of chain at work, increases the service life.
The utility model mainly is able to solve through following technical proposals: a kind of lift lift chain; Comprise inner plate; Outer plate, roll sleeve pin and rivet is characterized in that described outer plate comprises the base plate that is connected through rivet with inner plate, and the both sides of said base plate form the flap that turns up.
Described roll sleeve pin comprises the roller that cooperatively interacts, bearing pin and sleeve, and the internal diameter of said roller and the matching gap of sleeve outer diameter are not more than 0.3mm, and the internal diameter of said sleeve is not more than 0.2mm with cooperating of the external diameter of bearing pin.
The gap of said inner plate and sleeve is not more than 1.5mm, and the gap of said outer plate and inner plate is not more than 2mm.
The quenching hardness of said roller is HRC56-60, and the quenching hardness of said sleeve is HRC42-48, and the quenching hardness of said bearing pin is HRC40-45, and the quenching hardness of said carrier bar is HRC25-30.
The utility model has changed the shape of outer plate, has reduced the surface of contact of outer plate and hopper, makes the each several part of chain stressed evenly.Increase the gap of bearing pin and carrier bar, can effectively alleviate the situation of rocking.The lift chain of the utility model has working stability and long working life preferably.

Fig. 2 is the schematic cross-section of outer plate.
Fig. 3 is the structural representation of roll sleeve pin.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
A kind of lift lift chain as shown in Figure 1 comprises inner plate 1, and outer plate 2, roll sleeve pin 3 and rivet 4, outer plate 2 comprise the base plate 21 that is connected through rivet 4 with inner plate 1, and the both sides of base plate 21 form the flap 22 that turns up.Roll sleeve pin 3 comprises the roller 32 that cooperatively interacts, bearing pin 31 and sleeve 33, the matching gap of the internal diameter of roller 32 and sleeve 33 external diameters is not more than 0.3mm, the internal diameter of sleeve 33 with the cooperating of external diameter of bearing pin 31 be not more than 0.2mm.Inner plate 1 is not more than 1.5mm with the gap of sleeve 33, and outer plate 2 is not more than 2mm with the gap of inner plate 1.The quenching hardness of roller 32 is HRC56-60, and the quenching hardness of sleeve 33 is HRC42-48, and the quenching hardness of bearing pin 31 is HRC40-45, and the quenching hardness of inside and outside carrier bar is HRC25-30.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection domain that belongs to the utility model.
