Abstract
The utility model relates to a rubber bearing plate for a quick road weighting machine, which is characterized in that a metal frame is completely coated with ethylene-propylene-diene monomer (EPDM) rubber, the thickness of the rubber is 1 to 3mm, the curvature in the length direction is less than 1.5mm, the structure is in a U shape, convex plates are arranged on the two sides, and the middle part is convex. The utility model has the advantages that: 1, the reliability is high, the service life is long, and the service life of the rubber bearing plate can reach 30 million times; 2, the protection grade is high due to the fully rubber-sealed structure, compared with the pure metal structure, the protection grade is improved to IP68 from IP66, and the plate can be normally used in rainwater for long time; 3, the anti-slip property is good, the rubber-covered metal effectively improves the adhesive force of the tyre, and the safety of vehicles running in rainy and snowy day is improved; 4, the use temperature range is between 45 DEG C below zero to 85 DEG C, meeting the use requirement of different north and south regions; and 5, with the alloy steel composite structural bearing plate coated with the ethylene-propylene-diene monomer (EPDM) rubber, the material has higher temperature-resist grade, wider temperature range, and good corrosion-resistant and ageing resistant performance, and can meet the post-processing of the bearing plate.
Description
One, technical field
The utility model relates to the quick weighing machine of a kind of highway rubber bearing plate.
Two, background technology
The quick weighing machine of highway to vehicle overload, overload detection, weight metering charging and scientific research, provides the foundation of science with rubber bearing plate widespread use road, bridge, tunnel for highway construction, planning, maintenance.Weighing machine rubber bearing plate plays vehicle weight, anti-oxidant, anticorrosion, moistureproof to protect the vital role of electronic devices and components.
Three, summary of the invention
The purpose of this utility model provides the quick weighing machine of a kind of highway rubber bearing plate, and it has vehicle weight, anti-oxidant, anticorrosion, moistureproof to protect the effect of electronic devices and components.
The utility model purpose is achieved like this: it comprises metal bearing plate and rubber, it is characterized in that: on the metal bearing plate, be pasted with one deck rubber layer comprehensively, the rubber layer of on the metal bearing plate, pasting, its structure is " recessed " word shape, and there is boss on both sides, intermediate recess, the rubber layer that sticks on below the metal bearing plate is a plane layer, 1～3 millimeter of the rubber layer rubber thickness of being pasted, less than 1.5 millimeters, the rubber of being pasted is ethylene-propylene-diene rubber in the length direction flexibility.
The utility model has designed ethylene-propylene-diene rubber voluntarily and has coated the bearing plate structure according to the concrete operating position of the quick weighing machine of highway.The condition of work of rubber bearing plate is-45 ℃～160 ℃, requires to carry pressure 150kg/cm
2, overload capacity 200% was not less than 5 years serviceable life.Select ageing properties and superior ethylene-propylene-diene rubber (EPDM) material of mechanical property to fill a prescription as the elastomer body material development.Ethylene-propylene-diene rubber is made up of chemically stable saturated hydrogen because of its molecular backbone, nonpolarity substituting group in the molecule, intermolecular cohesive energy is low, thereby low temperature resistant, high temperature resistant aging, ozone resistance, there is significantly technical advantage the shop characteristic aspect, adopt the HRH binding system and use the bonding system of silane coupling agent, make the bonding strength of ethylene-propylene-diene rubber and 42CrMo reach 8.1MPa, after 160 ℃ * 12H is aging, performance also keeps 7.0MPa, show as in the bonding strength experimentation bonding plane and keep good, elastomeric material destroys prior to bonding plane, satisfies the rubber bearing plate fully to the requirement of rubber adhesive property.
Specific performance index such as table 1.
