Steel wire anchoring device for doubling method construction of main cable of suspension bridge
The invention relates to a steel wire anchoring device for doubling method construction of a main cable of a suspension bridge. The device at least comprises movable rods, fixed rods, an eight-wire clamping device, a four-wire clamping device, a rigging turnbuckle, an upper steel wire rope clamp, a lower steel wire rope clamp, a steel wire rope, a catwalk large cross beam, a catwalk rope and a cross rod, wherein two vertical rods are respectively formed by upper and lower connection of two movable rods and two fixed rods, a cross rod is vertically connected between the fixing rods of the two vertical rods, and the bottoms of the two fixing rods are connected with a catwalk large cross beam; two ends of the top of the movable rod of each vertical rod enable the two steel wire ropes to be obliquely pulled through rigging turnbuckles, upper steel wire rope clamps and lower steel wire rope clamps to form straight triangles which are symmetrical left and right with the corresponding vertical rod as the center; an upper end of each steel wire rope is fixed on the top of the movable rod through a rigging turnbuckle, and a lower end is fixed on the catwalk rope through a lower steel wire rope clamp; an eight-wire clamping device is further fixed to the top of each movable rod, two sets of four-wire clamping devices are fixed to the transverse rod, and the two vertical rods are symmetrically arranged about the center line of a catwalk.
本发明涉及一种悬索桥主缆纺线法施工钢丝锚固装置，至少包括活动杆、固定杆、八丝夹丝器、四丝夹丝器、索具螺旋扣、上钢丝绳夹、下钢丝绳夹、钢丝绳、猫道大横梁、猫道绳和横杆，由两根活动杆和两根固定杆上下连接分别构成两个根立杆，两根立杆的固定杆之间垂直连接横杆，两个固定杆底部与猫道大横梁连接；每根立杆的活动杆顶部两端均通过索具螺旋扣、上钢丝绳夹、下钢丝绳夹将两根钢丝绳斜拉成以立杆为中心，左右对称的直边三角形；每根钢丝绳上端通过索具螺旋扣固定在活动杆的顶部，下端通过下钢丝绳夹固定在猫道绳上；在每个活动杆的顶部还固定有八丝夹丝器，在横杆上固定两组四丝夹丝器，两个立杆以猫道中心线为对称设置。
