Description
Technical field
The utility model relates to a kind of test unit, specifically is a kind of suspension bridge cord clip skid-resistance tester.
Background technology
Referring to Fig. 1, Fig. 2 and Fig. 3: the load of suspension bridge bridge floor (107) passes to main push-towing rope (101) by hoist cable (106), cord clip (102), and cord clip (102) adopts bolt affixed with main push-towing rope (101).Because the linearity of main push-towing rope (101) is a catenary, main push-towing rope (101) constitutes different angles with bridge floor (107) horizontal direction, and the pulling force of hoist cable (106) can not be greater than the frictional resistance of cord clip (102) with main push-towing rope (101) along the component of main push-towing rope (101) catenary.If the pulling force of hoist cable (106) greater than the frictional resistance of cord clip (102) with main push-towing rope (101), will cause cord clip (102) to glide along main push-towing rope (101) along the component of main push-towing rope (101) catenary, influence bridge security.
Be to guarantee the safety of suspension bridge, in the material of main push-towing rope and cord clip, when bigger variation takes place structure, all tackle the supporting application cord clip of main push-towing rope and do the safety testing that antiskid moves.The traditional experiment method is to realize in the mode of simulating practical working situation, its test unit comprises main push-towing rope (101), cord clip (102), lifting jack (103) and worktable (105), the two ends of main push-towing rope (101) are respectively by stationary installation (104) banding and be supported on the worktable (105), main push-towing rope (101) is in tilted layout, angle with worktable (105) formation certain angle, on cord clip (102), apply pulling force by lifting jack (103), during with the cord clip slippage on the cord clip contrast of maximum pull (T) and practical working situation pulling force calculate cord clip safety coefficient (the maximum sliding force F=T*COS of cord clip α).This test unit is in process of the test, because main push-towing rope (101) is subjected to the pulling force of vertical table (105) direction, main push-towing rope (101) bending, original cord clip setting angle (α) is changed, cause the maximum sliding force of the cord clip that calculates (F) accurate inadequately, directly influence the test findings of cord clip safety coefficient; In addition, main push-towing rope (101) the unsettled layout and stressed that tilts has in test proposed higher technical requirement to the stationary installation (104) at main push-towing rope (101) two ends, makes the process of the test complexity, and the test period is long.
Summary of the invention
The purpose of this utility model is: at above-mentioned the deficiencies in the prior art, provide a kind of test findings accurate, simple to operate, suspension bridge cord clip skid-resistance tester fast and easily.
The utility model adopts following technical proposals to realize its technical purpose.
A kind of suspension bridge cord clip skid-resistance tester, comprise main push-towing rope and worktable, described main push-towing rope supports by cushion block and is placed on the worktable, the two ends of main push-towing rope are respectively with the fastener banding, stop cord clip and test cord clip are installed on the described main push-towing rope, on the main push-towing rope between stop cord clip and the test cord clip, two baffle plates are installed, are provided with lifting jack between two baffle plates; The bottom of described lifting jack is against on the baffle plate at place, stop cord clip end, and the top is against on the baffle plate at place, test cord clip end; Be furnished with pressure transducer between the baffle plate at described test cord clip and place, its end, pressure transducer links to each other with dynamic data collection system.
The top of described lifting jack is against on the baffle plate at place, test cord clip end by spheric washer.
Described lifting jack is a plurality of, and these lifting jack evenly distribute around main push-towing rope.
Described main push-towing rope and worktable are parallel to each other.
Described fastener is fastening cord clip.
The beneficial effects of the utility model are: the maximum jacking force of the test unit of said structure during with the cord clip slippage directly draws the maximum friction resistance of cord clip and main push-towing rope, the coupling mechanism force ratio of maximum friction resistance and cord clip is the coefficient of friction resistance, and the antiskid that has had the coefficient of friction resistance, cord clip and main push-towing rope angle, cord clip coupling mechanism force just can check out the cord clip that tries fast moves security.This test unit has characteristics such as test findings is accurate, simple to operate, efficient and convenient and reliable and stable.
