Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and resistance to wears, the sling of suspension bridge structure of waterproof.
The purpose of this utility model is achieved in that a kind of suspension bridge resistance to wears, water proof type hoist cable structure, comprises hoist cable cable body, anchor cup, case beam otic placode and main push-towing rope cord clip.The steel wire of hoist cable cable body end separately, insert in the anchor cup, at anchor cup rear portion branch sleeve is set, the front end of anchor cup arranges internal thread, and be connected with case beam otic placode by screw thread, between case beam otic placode and the anchor cup waterproof cover is set, case beam otic placode adopts bearing pin to be connected with cord clip, between cord clip hole and case beam lug plate holes and bearing pin, axle sleeve is installed, described axle sleeve arranges the orderly many through holes of arrangement, solid lubricant inlaid in through hole take high tensile metal as matrix on its surface, matrix material is tin bronze, and kollag is graphite; The bearing pin protective cover is installed in end at bearing pin 3.
The utility model suspension bridge resistance to wears, water proof type hoist cable structure; described this bearing pin protective cover is connected on the case beam otic placode in the following manner: thread mill drilling around case beam otic placode upper pin; process unthreaded hole on the flange of this bearing pin protective cover; by screw the bearing pin protective cover is connected with case beam otic placode; between the flange of case beam otic placode and bearing pin protective cover sealing mat is installed, gasket material adopts silicon rubber.
The utility model suspension bridge resistance to wears, water proof type hoist cable structure, and described bearing pin bearing pin protective cover adopts stainless steel material to make, and can prevent that moisture from entering pin shaft hole, causes corrosion, causes the bearing pin hoist cable to lose efficacy.
The utility model axle sleeve with high tensile metal as matrix, to satisfy the carrying condition of sling of suspension bridge axle sleeve heavy duty, make axle sleeve have self-lubricating property by solid lubricant inlaid simultaneously, the needs of the harsh working condition such as satisfy that the lubricated difficulty of sling of suspension bridge bearing pin maybe can not be lubricated.Therefore this hoist cable shaft sleeve of pin shaft has supporting capacity height, wear-resisting, the multiple advantage such as antifriction performance is good, delays hoist cable to change the time and reduce hoist cable replacing number of times the application life that can greatly improve sling of suspension bridge, reduces the maintenance cost of whole bridge.
The beneficial effects of the utility model are:
Employing the utility model structure is resistance to worn, waterproof, can improve the safety and reliability of sling of suspension bridge, reduces the replacing number of times of hoist cable.
