Adopt technique scheme, technique effect of the present invention has:
Pole in the present invention adopts carbon fiber enhancement resin base composite material to make, and its tool has the following advantages:
(1) there is high specific strength and specific modulus; Density is low, and its intensity is about 4 times of high strength steel and aluminium alloys, 2 times of glass fiber reinforced plastic; Specific modulus is 3 times of glass fiber reinforced plastic.
(2) endurance; In the quiescent state, carbon fiber/epoxy matrix composite circulate 105 times, bear 90% ultimate strength stress time just destroyed, and steel can only bear about 50% of ultimate strength.
(3) coefficient of thermal expansion is little; The thermalexpansioncoefficientα of carbon fiber has significant anisotropy, makes the α of its composite material also have anisotropy.
(4) abrasion-resistant, resistance to wears; Carbon fiber enhancement resin base composite material has the characteristic that excellent fatigue-resistance characteristics, coefficient of thermal expansion are little and thermal conductivity is high, tool abrasion-resistant, wear-resistant key property.
(5) good corrosion resistance.The corrosion resistance of carbon fiber is very excellent, and in acid, alkali, salt and solvent, long-term immersion can not swellingly be gone bad.
(6) water-tolerant.Carbon fiber enhancement resin base composite material can use for a long time in wet environment and water.General higher along the strength retention of machine direction, the conservation rate perpendicular to machine direction is lower.
(7) good conductivity; Carbon fiber has electric conductivity.
Pole in the present invention have employed pipe as main material, and integrated member adopts assembling design, and multiple standard knot is by Flange joint, requires design standard mould, be convenient to realize mass production, facilitate processing and manufacturing according to different lifting capacity; The present invention adopts software ANSYS element of construction optimal design, reduces pole sectional dimension and weight, is convenient to mountain area transport and uses; Adopt inner flange connected mode in pole design, the external diameter of flange is less than the external diameter of standard knot, does not have projection obstacle when pole is promoted, and promotes smooth and easy.
