[Abstract]:Hydraulic lifting equipment is mainly used in the field of engineering construction to complete the lifting of heavy objects, hydraulic lifting technology has been rapid development and application in recent decades. It has its unique design, simple construction methods. Advanced automatic control and full safety and reliability are favored by more and more construction units. This paper analyzes and studies the phenomenon of adhesion between anchor ring and anchor piece in the working process. The research contents are as follows: 1. Firstly, the structure and working principle of hydraulic lifting equipment are analyzed. The main structure and motion principle of intermittent hydraulic lifting equipment are described. Combined with the working mode of anchor ring / anchor plate, the experimental instruments and devices required for its bonding characteristics are introduced and designed in detail. 2. The influence of surface roughness factors on friction characteristics between anchor rings and anchors is studied theoretically and experimentally. Based on fractal theory, the surface roughness model between anchor rings and anchors is established, and the experimental device is designed. Two groups of anchor ring / plate specimens with different roughness were tested, and the influence of surface roughness factors on friction characteristics between anchor rings and anchors was analyzed. The influence of lubrication factors on the friction characteristics between anchor rings and anchors is studied. Firstly, a mathematical model of lubrication between anchor rings and plates is established. Secondly, the experiment was carried out with or without lubrication conditions, and the influence of lubrication factors on the friction characteristics between the anchor ring and the anchor plate was analyzed. The influence of surface coating factors on the friction characteristics between anchor rings and anchors was studied and analyzed. The friction mechanism of surface coatings and common coatings were analyzed in detail. The Ni-P coating was designed. The two groups of low temperature ion sulphurizing coatings are used in the test of two kinds of coatings, the anchor ring / the anchor plate are used in the test, and the designed experimental device is used. The friction characteristics of two different coatings are compared and analyzed. In this paper, the friction characteristics of the key parts of the anchor ring / anchor plate in hydraulic lifting equipment are studied to improve the working conditions of the anchor ring / anchor plate. By studying the friction mechanism between the anchor ring and the anchor plate, the working conditions of the anchor ring / anchor plate are improved effectively and its service life is increased. The research results are of great practical significance for improving the overall level of hydraulic integral lifting technology and enhancing the international competitiveness of our country in the field of application of this technology.
