Abstract
The utility model relates to a connecting rod lifting mechanism, which comprises a lifting oil cylinder, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod and an intermediate connecting rod; the first connecting rod and the second connecting rod constitute a group of parallel connecting rods; the third connecting rod and the fourth connecting rod constitute an another group of parallel connecting rods; the two groups of the connecting rods constitute a group of parallelograms; the first connecting rod and the fourth connecting rod are connected to the intermediate connecting rod respectively; both ends of the lifting oil cylinder are connected to the first connecting rod and the fourth connecting rod respectively, and the connection position is far from the intermediate connecting rod; the first group of the connecting rods is raised under the driving action of the lifting oil cylinder, the intermediate connecting rod drives the second group of the connecting rods to be raised at the same time, and the height required for lifting of the mechanism is achieved along with the extension of a piston rod of the oil cylinder. The linkage of the two groups of the four connecting rods is realized by using one set of the oil cylinders, so that the connecting rod lifting mechanism has the advantages of simple structure, saved cost, small occupied space during the storage, relatively lower processing difficulty and mass production.
Description
Technical field
The utility model relates to a kind of lifting mechanism that is applied in the construction machinery products such as various boom type high-altitude operation platforms.
Background technology
Than traditional lifting mechanism, the utility model adopts the parallel connecting rod that hoists of two group of four bar to realize hoisting of mechanism, and being has bigger improvement and an innovation on traditional lifting mechanism.
The utility model content
The purpose of this utility model provides a kind of connecting rod lifting mechanism.
The purpose of this utility model is achieved through the following technical solutions.
A kind of connecting rod lifting mechanism, comprise lift oil tank, first connecting rod, second connecting rod, third connecting rod, the 4th connecting rod and intermediate connecting rod, wherein first connecting rod and second connecting rod are formed one group of parallel rod, third connecting rod and the 4th connecting rod are formed another group parallel rod, two groups of connecting rods are formed one group of parallelogram respectively, first connecting rod and the 4th connecting rod are connected respectively on the intermediate connecting rod, and the two ends of described lift oil tank are connected respectively on first connecting rod and the 4th connecting rod, and the bonded assembly position is away from intermediate connecting rod.
Under the drive of lift oil tank, first group of connecting rod hoists, and drives second group of connecting rod by intermediate connecting rod and hoists simultaneously, along with the piston rod of oil cylinder stretches out, mechanism hoisted meet the requirements of height.
The utility model overlaps the motion that oil cylinder has reached two group of four connecting rod with one, and is simple in structure, saved cost; And it is little to take up room during collection; Simultaneously, the difficulty of processing is less relatively, is fit to produce in enormous quantities.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a connecting rod lifting mechanism constructional drawing under normal circumstances;
Fig. 2 is the constructional drawing of connecting rod lifting mechanism under the state of hoisting.
The specific embodiment
Shown in Fig. 1-2, a kind of connecting rod lifting mechanism, comprise lift oil tank 5, first connecting rod 1, second connecting rod 2, third connecting rod 3, the 4th connecting rod 4 and intermediate connecting rod 6, wherein first connecting rod 1 and second connecting rod 2 are formed one group of parallel rod, third connecting rod 3 and the 4th connecting rod 4 are formed another group parallel rod, two groups of connecting rods are formed one group of parallelogram respectively, first connecting rod 1 and the 4th connecting rod 4 are connected respectively on the intermediate connecting rod 6, and the two ends of described lift oil tank 5 are connected respectively on first connecting rod 1 and the 4th connecting rod 4, and the bonded assembly position is away from intermediate connecting rod 6.
Under the drive of lift oil tank, first group of connecting rod hoists, and drives second group of connecting rod by intermediate connecting rod and hoists simultaneously, along with the piston rod of oil cylinder stretches out, mechanism hoisted meet the requirements of height.
The utility model overlaps the interlock that oil cylinder has reached two group of four connecting rod with one, and is simple in structure, saved cost; And it is little to take up room during collection; Simultaneously, the difficulty of processing is less relatively, is fit to produce in enormous quantities.
Person skilled in the art should be familiar with, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
