Description
One, technical field:
The utility model belongs to the field tests of wind power generation blade, and it is test bed to relate in particular to the bolt sleeve static(al).
Two, background technology:
Wind wheel blade is the critical component of wind power generating set, and its structure is very complicated, and geometric shape is also extremely irregular; Blade moves stressed complexity and load is not easy accurately to determine; The used variety of raw material specification of production blade is more, performance is dispersed big; Different production technologies is bigger to the intensity and the quality influence of blade.The bolt sleeve ability of pulling of testing the testpieces identical with the aliquot of root of blade is correctness, the reliability of checking root of blade design, the rationality of manufacturing process and the actual bearer ability of assessment blade root structure and a kind of effective means in serviceable life.The bolt sleeve of existing testing experiment spare pulls that the bolt sleeve static(al) of ability is test bed to be made up of frame, hydraulic cylinder and tensimeter.Its pressure cylinder diameter is little, and oil hydraulic system pressure is low, and pulling force is little, can not reach the design load requirement.Frame is separated with test body, and the poor stability of test body influences measuring accuracy.Tensimeter pressure changes greatly, and test error is big.The test bed variation relation that can not monitor loading force and bolt sleeve displacement in real time of existing bolt sleeve static(al).
Three, utility model content:
The purpose of this utility model is exactly to solve now with the problems referred to above that exist in the technology, provides a kind of pulling force big, the good stability of test body, and the bolt sleeve static(al) that measuring accuracy is high is test bed.
For finishing the purpose of this utility model, its technical solution is: a kind of bolt sleeve static(al) is test bed, and it comprises support, the upper plate that is fixed together with support, middle plate, clamp crossbeam and bottom plate, hydraulic cylinder, measured object fishbolt, pull bar, stress bolt, depression bar, hydraulic pump, force cell, motor and data acquisition system (DAS); Hydraulic cylinder places on the upper plate of cantilever tip, its piston-rod lower end removably is fixed on the force cell upper end, the force cell lower end removably is fixed with pull bar, the lower end of pull bar is fixed with the attaching nut, the stress bolt that attaching nut lower end clip has the other end and the tested bolt sleeve of test body to be threaded, when compressing, depression bar withstands on the middle plate of support by jacking block; Hydraulic cylinder connects hydraulic pump by oil pipe, and hydraulic pump is by motor-driven or manual drives; Force cell connects data acquisition system (DAS), and there is the measured object fishbolt on the two sides that clamps crossbeam.
Above-mentioned described the utility model also comprises dial gauge, and it is fixed near the support of test body, and its contact is pressed on the tested bolt sleeve.
Above-mentioned described jacking block of the present utility model lower end is the ball-and-socket shape, the upper end of depression bar be the ball-and-socket shape with the jacking block lower end be complementary spherical, jacking block places on the depression bar, when compressing, it withstands on the middle plate of support.Like this, jacking block is unfixing, can change its size at any time as required, and is to adapt to the depression bar of different bulbs, very easy to use.
The utility model is to the blade root load-bearing capacity, it mainly is the test of the ability that pulls of the employed bolt sleeve of blade root, it adopts and tested blade root same model and technology, the testpieces that have three bolt sleeves identical with a part of structure of tested blade root tested, during test, the testpieces upper end is by measured object fishbolt maintenance, stress bolt is tightened in the tested bolt sleeve, depression bar is tightened in the bolt sleeve of its both sides, start hydraulic pump, piston rod is up, and tension stress bolt, depression bar then withstand on the middle plate tightly, draw in the middle of adopting, the mode that press on both sides exerts pressure for middle bolt sleeve, it is pulled, and force cell sends the power that applies to data acquisition system (DAS), thereby predicts the pulling-out force that bolt sleeve can bear.The utility model oil hydraulic system pressure is big, and pulling force is big, can reach the design load requirement.The measured object fishbolt that clamps the crossbeam two sides clamps testpieces, has increased its stability, and the pulling-out force of stress bolt can deflection, the accuracy of measurement height.Force cell and data acquisition system (DAS) precision height, test error is little, the accuracy of measurement height.Change by dial gauge monitoring blade root bolt sleeve displacement.In a word, the utility model is simple in structure, and pulling force is big, and data presentation is directly perceived, accuracy of measurement is high, and the good stability of test body is easy to use.Can monitor the variation relation of loading force and bolt sleeve displacement in real time.
