The technical scheme of the utility model solve the in -process chain end that the chain was being put to chain elevator among the prior art effectively and strikeed too big problem with the lifting machine.
Description
Technical field
The utility model is related to wind-powered electricity generation technical field of auxiliary equipment, in particular to the chain on a kind of chain elevator
Bar buffer unit.
Background technology
At present, it is typically necessary work high above the ground in wind power generation field.People is conveyed between aerial work platform and ground
Member's goods and materials and maintenance are required for using certain jacking equipment.This jacking equipment can convey personnel's goods and materials, while also needing
To consider many factors such as actual working environment, the security of lowering or hoisting gear.
The end of the chain of chain elevator of the prior art and chain elevator main body are provided with electronic stopper, and one
Denier electrical control is failed, and electronic stopper does not work, and chain end can strike elevator main body, cause elevator and chain
Damage.
The content of the invention
Main purpose of the present utility model is to provide a kind of chain elevator chain buffer unit, to solve prior art
In problem.
To achieve these goals, the utility model provides a kind of chain elevator chain buffer unit, including：It is fixed
Plate, certain position being fixed on outside mechanism, as the support of this mechanism；Upper buffer spring, totally three, positioned at fixed plate and work
Between dynamic plate；Lower buffer spring；Chain；Portable plate, can move up and down.
Further, upper buffer spring has three, is distributed between fixed plate and portable plate, with the movement of portable plate,
Upper buffer spring can be compressed, and absorb part energy, play a part of buffering.
Further, studs upper end passes through fixed plate in upper buffer spring, and by upper trip bolt studs is made
Connect together with fixed plate.
Further, fairlead is riveted with portable plate, and fairlead passes through studs, upper buffer spring upper end and fixed plate
Lower plane is contacted, plane contact on upper buffer spring lower end and fixed plate.
Further, lower end trip bolt is made up of two hex-head nuts, is fixed to studs lower end, plays spacing work
With preventing portable plate from sliding from studs.
Using the technical solution of the utility model, chain elevator chain buffer unit is arranged on into chain elevator chain
End, when chain elevator puts chain to chain end, Upper gasket can first touch portable plate lower surface, this buffering elastic at present
Spring is compressed, and absorbs part energy, plays cushioning effect, if operating personnel do not have found that chain has been discharged, continues to put chain,
Portable plate will be moved up, and upper buffer spring is compressed, again energy absorption, plays cushioning effect.
Description of the drawings

Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and in conjunction with the embodiments describing the utility model in detail.
As shown in figure 1, the chain elevator chain buffer unit of the present embodiment include fixed plate 10, upper buffer spring 20,
Lower buffer spring 30, chain 40 and portable plate 50.Chain 40 sequentially passes through from top to bottom fixed plate 10, portable plate 50 and lower buffering
Spring 30.Said structure is simple, simple installation, reduces the labour intensity of operating personnel, improves operating efficiency.
Using the chain buffer unit on the chain elevator of the present embodiment, when chain 40 is moved up, lower buffer spring
30 and upper buffer spring 20 compressed, energy absorption reaches buffering purpose.
As shown in Fig. 2 upper buffer unit 20 includes upper clamp nut 21, studs 22, upper buffer spring main body 23, leads
To set 24, lower clamp nut 25.Studs 22 sequentially passes through clamp nut 21, upper buffer spring main body 23, fairlead 24, work
Dynamic plate 50, lower clamp nut 25.Said structure is simple, simple installation, reduces the labour intensity of operating personnel, improves work effect
Rate.
Alternatively, certain pretightning force is needed between portable plate 50 and upper buffer spring main body 23, this pretightning force can be by under
Clamp nut 25 is adjusted.Can change the energy absorption of upper buffer spring 20 by changing the initial compression amount of upper buffer spring 20
Initial value.
Optionally, the specification of upper buffer spring main body 23 can change, the different spring of specification, and the size of energy absorption is not
Together.Optionally, spring structure is simple, and simple processing is with low cost.
As shown in figure 3, lower buffer unit 30 includes Upper gasket 31, lower buffer spring main body 32, lower gasket 33, block 34.
Chain 40 sequentially passes through Upper gasket 31, lower buffer spring main body 32, lower gasket 33, block 34.Said structure is simple, installs letter
Just, the labour intensity of operating personnel is reduced, operating efficiency is improved.
Optionally, the specification of lower buffer spring main body 32 can change, the different spring of specification, the size of energy absorption
It is different.Optionally, spring structure is simple, and simple processing is with low cost.
