Abstract
The utility model discloses a project machine bearing pull rod made of a carbon fibre composite. The project machine bearing pull rod comprises a pre-set steel core, wherein a carbon fibre composite layer is covered outside the steel core; the steel core comprises steel pull rings arranged at the head and tail ends of the steel core, a steel reinforced connecting component is arranged between the two steel pull rings, and the cross section of the steel reinforced connecting component is in an H shape; the bearing pull rod is made of the carbon fibre composite, the tensile strength of the pull rod in a using process is strengthened through the pre-set steel core, the spreading design of carbon fiber prewashing cloth is convenient, and the linearity of the bearing pull rod is insured; and the project machine bearing pull rod made of the carbon fibre composite is used for a project machine, the self weight of the project machine is reduced, the domain load is reduced, the barycenter is further reduced, and the stability of the project machine is improved. The project machine bearing pull rod made of the carbon fibre composite provided by the utility model has the advantages that the fatigue resistance is good, and the service life of the project machine bearing pull rod is prolonged by twice compared with the traditional metal pull rod.
Description
Technical field
The utility model relates to a kind of engineering machinery load-bearing pull bar, particularly a kind of carbon fiber composite engineering machinery load-bearing pull bar.
Background technique
Load-bearing pull bar in the market, no matter length is all take metal alloy as raw material.Domestic metallic material technological accumulation is abundant, and manufacturing process is ripe, and therefore excellent product performance is widely used in industry-by-industry, and especially at the heavy industry mechanical field, high-performance metal materials has very important status especially.But metallic material is when having excellent performance, has that the defective that can't ignore---quality is large.Along with the update of engineering machinery, every new design constantly is born, and the short slab of metallic material quality aspect is outstanding all the more, becomes the bottleneck that the engineering machinery field development slowly can't make a breakthrough.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, has proposed a kind of light weight high-strength, antifatigue, the carbon fiber composite engineering machinery load-bearing pull bar of long service life.
The technical problems to be solved in the utility model is achieved through the following technical solutions, and a kind of carbon fiber composite engineering machinery load-bearing pull bar is characterized in: comprise default steel core, be coated with the carbon fiber composite layer at steel core.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and described steel core comprises the steel draw ring that is arranged on the head and the tail two ends, is provided with steel reinforced company connection member between two steel draw rings.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and the cross section of described steel reinforced company connection member is H shape.
The utility model compared with prior art adopts carbon fiber composite to make the load-bearing pull bar, by default steel core, not only strengthens pull bar tensile strength in use, also the aspect laying design of carbon fibre initial rinse fabric, ensure the straightness accuracy of load-bearing pull bar.Carbon fiber composite density is little, is only traditional steel 1/5th, and Novel pull rod comes into operation and can greatly alleviate the weight of engineering machinery, when reducing energy consumption, relaxes the burden of road and construction site.Carbon fiber resin composite material tensile strength is generally all more than 3500Mpa, 7 ~ 9 times of steel, tensile modulus of elasticity be 230 ~ 430Gpa also higher than steel, carbon fiber composite load-bearing pull bar has better mechanical strength, bearing capacity can reach 225 tons, and safety coefficient is higher.The use of carbon fiber composite load-bearing pull bar on engineering machinery can make engineering machinery deadweight reduce, and reduces the domain load, and the further reduction of center of gravity has improved the stability of engineering machinery.Carbon fiber composite load-bearing pull bar fatigue resistance is splendid, and the traditional metal pull bar, extend one times working life relatively.
Description of drawings
Fig. 1 is structure diagram of the present utility model.
Fig. 2 is the sectional view of steel reinforced company connection member.
Embodiment
A kind of carbon fiber composite engineering machinery load-bearing pull bar comprises default steel core, is coated with carbon fiber composite layer 2 at steel core.Described steel core comprises the steel draw ring that is arranged on the head and the tail two ends, is provided with steel reinforced company connection member 1 between two steel draw rings.The cross section of described steel reinforced company connection member 1 can be set to H shape.
Made by technique global formations such as cutting, laying design, pre-buried steel core, the curing that vacuumizes, heats up by carbon fiber ring epoxy resins preimpregnation cloth.This kind advanced composite material (ACM) load-bearing pull bar is compared the traditional metal pull bar and is had numerous outstanding advantages such as light weight is high-strength, corrosion-resistant, fatigue resistance is splendid.
Concrete moulding process flow process is as follows:
According to the pre-buried steel draw ring of user demand design and steel reinforced company connection member; Carry out the laying design according to pull bar size and requirement of strength, determine laying thickness, laying scheme; After the laying design reaches the plan number of plies, fill up the hole of draw ring and connection part; Semi-finished product cover airbag vacuumizes, and ensures that resin distribution is even; Mould is placed in the fixed line stove, heats up and solidify; After solidifying, to product polish, application.
