Rubber pulling pipe and steel strand installation construction method and limiting pulling device
The invention relates to the technical field of rubber drawing pipe and steel strand installation, in particular to a rubber drawing pipe and steel strand installation construction method and a limiting drawing device. The outer diameter of the end, close to a pressing plate, of an expanding conical ring is smaller than the inner diameter of a stepped groove, and the outer diameter of the other end of the expanding conical ring is larger than the inner diameter of the stepped groove; the diameter-expanding conical ring is pressed on the inner wall of the rubber drawing pipe, and a pull ring is arranged on the outer side of the diameter-expanding conical ring. The steel strand pulling device has the advantages that the stepped groove is formed in the end opening of an existing rubber drawing pipe, the limiting drawing device is arranged in the stepped groove, and the purposes of fixing a steel strand and laterally fixing the end opening of the rubber drawing pipe are achieved through the limiting drawing device; winding limiting of the ends of the steel strands is achieved through the upper inserting rod, relative pressing of the winding ends is achieved through extrusion, the ends of the steel strands are extruded mutually, friction between the steel strands is increased, friction between the steel strands and the upper inserting rod is increased, and therefore the requirement for clamping force is lowered, and clamping stability is improved.
本发明涉及橡胶抽拔管和钢绞线安装技术领域，具体为橡胶抽拔管和钢绞线安装施工方法及限位抽拔装置，扩径锥环靠近压板的一端外径小于阶梯槽的内径，扩径锥环的另一端外径大于阶梯槽的内径，扩径锥环压合在橡胶抽拔管的内壁上，扩径锥环的外侧设置有拉环，有益效果为：通过在现有的橡胶抽拔管的端口设置阶梯槽，并在阶梯槽中设置限位抽拔装置，通过限位抽拔装置实现固定钢绞线、侧向固定橡胶抽拔管端口的目的，利用上插杆实现钢绞线端部的缠绕限定，利用挤压实现缠绕端的相对压合，使得钢绞线端部相互挤压，既增大了钢绞线之间的摩擦，又增大与钢绞线与上插杆之间的摩擦，从而降低了对夹持力的要求，提高了夹持的稳定性。
