External prestress steel strand steering gear
The invention discloses an external prestressing steel strand steering gear, which relates to the technical field of steering gears, and specifically comprises a steel pipe sleeve, the steel pipe sleeve is of an arc-shaped structure, a steel strand is arranged in the steel pipe sleeve, the outer surface of the steel strand is wrapped with an antirust sleeve, the two ends of the steel pipe sleeve extend to be provided with first fixing rings, and the two ends of the steel pipe sleeve are symmetrically provided with connecting pipes; the ends, close to the steel pipe sleeve, of the two connecting pipes extend to form second fixing rings, and the ends, close to the steel pipe sleeve, of the second fixing rings abut against the end faces of the first fixing rings. The connecting pipes are connected to the two ends of the steel pipe sleeve, the anti-rust sleeve on the outer surface of the steel strand can make contact with the arc faces in the connecting pipes, the steel strand is prevented from being damaged due to friction of the edges of the steel pipe sleeve during moving, the friction force between the inner wall of the steel pipe sleeve and the anti-rust sleeve can be reduced through the balls, and the anti-rust sleeve is prevented from being abraded; therefore, the steel strand can be prevented from being exposed in the external environment to be corroded, and the using effect is improved.
本发明公开了一种体外预应力钢绞线转向器，涉及转向器技术领域，具体包括钢管套，钢管套设为弧形结构，钢管套内部设有钢绞线，钢绞线外表面包裹防锈套，钢管套的两端均延伸设有第一固定环，钢管套两端对称设有连接管，两个连接管靠近钢管套的一端均延伸设有第二固定环，且第二固定环靠近钢管套的一端抵在第一固定环的端面上。本申请通过在钢管套的两端连接连接管，可使得钢绞线外表面的防锈套与连接管内部的弧面相接触，避免钢绞线在移动时受到钢管套棱边摩擦而损坏，再通过滚珠可降低钢管套内壁与防锈套之间的摩擦力，防止防锈套磨损，从而可避免钢绞线暴露在外部环境中被腐蚀，提高使用效果。
