Abstract

The invention provides a carbon fiber composite material reinforcing hydraulic oil cylinder, comprising a base, a cylinder barrel and oil openings. The oil openings are arranged at the both ends of the cylinder barrel; the cylinder barrel is a thinned metal cylinder barrel; a reinforcing layer is coated outside the cylinder barrel; the reinforcing layer is a carbon fiber composite material reinforcing layer; the carbon fiber composite material reinforcing layer uses heat convertible resin as a base body and a carbon fiber as a reinforcing material; and the carbon fiber composite material reinforcing layer contains the resin with a mass ratio of 23-55%. Compared with the full-metal hydraulic oil cylinder in the prior art, the strength, the rigidity and the anti-fatigue property of the carbon fiber composite material reinforcing hydraulic oil cylinder in various working conditions are improved by more than 20%, so that not only can the security of the product be effectively improved in the working conditions, but also more than 30% of the weight is reduced. Therefore, a mechanical pump truck is lightened, and the entire cost is reduced.

Description

technical field [0001] The invention relates to a hydraulic oil cylinder, in particular to a carbon fiber composite material reinforced hydraulic oil cylinder. Background technique [0002] At present, the domestic and foreign concrete construction machinery market is in short supply, which not only promotes the rapid development of the construction machinery industry, but also promotes the strong alliance of many enterprises, such as Zoomlion's merger with Italy's CIFA company, and Sany Heavy Industry's acquisition of an international giant in construction machinery Putzmeister Co. However, with the introduction of traffic laws and energy-saving and environmental protection requirements in various countries, the weight reduction of concrete construction machinery pump trucks with a pumping height of more than 30m has become an urgent problem to be solved. Weight reduction means lower energy consumption, higher pumping capacity and height, and can reduce manufacturin...
