Steel strand inhaul cable bundling device and rapid traction installation method
The invention discloses a bundling device of a steel strand inhaul cable and a rapid traction installation method, belongs to the technical field of steel strand inhaul cable traction, and solves the technical problem that in an existing traction installation method, each steel strand needs to be shredded and subjected to head upsetting. The bundling device comprises a water-drop-shaped buncher, the two ends of the water-drop-shaped buncher are respectively provided with a limiting section, the limiting sections are connected with limiting rings in a sleeved mode, gaps allowing the steel strand inhaul cables to penetrate through are formed between the limiting rings and the limiting sections, the end portions of the limiting sections are provided with limiting plugs enabling the steel strand inhaul cables to abut against the limiting rings, and one limiting plug is provided with a hanging ring. The water-drop-shaped buncher is combined with the limiting ring and the limiting plug, the water-drop-shaped appearance is designed, the shape of the cross section is changed, and therefore the friction angle of the center wire is changed, the friction contact length is increased, the friction force of the center wire is increased, and the friction force provides anchoring force needed by traction of the whole steel strand inhaul cable. The step of head upsetting of the center wire and extrusion of the center wire of the steel strand are reduced, and efficiency is improved.
本发明公开了一种钢绞线拉索的集束装置及快速牵引安装方法，属于钢绞线拉索牵引技术领域，解决现有牵引安装方法中每根钢绞线都要切丝墩头的技术问题。集束装置包括水滴型集束器，水滴型集束器的两端分别设有限位段，限位段套接有限位圈，限位圈与限位段之间设有用于穿过钢绞线拉索的间隙，限位段的端部设有将钢绞线拉索抵紧在限位圈的限位堵头，其中一个限位堵头设有吊环。利用水滴型集束器与限位圈、限位堵头的组合，设计水滴型外观改变横截面的形状，从而改变中心丝的摩擦角，加长摩擦接触长度，增加中心丝的摩擦力，摩擦力提供满足整束钢绞线拉索牵引所需的锚固力，减少了中心丝墩头的步骤和钢绞线中心丝的挤束，提高了效率。
