Problems solved by technology

The main saddle of this back cable structure is due to the integrated structure of the back cable anchor and the saddle body, and the protruding structure of the back cable anchor on the top of the saddle body, so that the distance between the top of the back cable anchor and the saddle groove of the saddle body is The vertical distance between them is too large, usually reaching 1.5-2.1m, which will increase the difficulty of processing the cable saddle body, especially the processing of the bottom surface of the saddle groove. However, the processing method of lengthening the overhang will make the rigidity of the spindle and / or the tool bar worse, which is prone to vibration, or even large vibration, and the processing quality is difficult to guarantee. The formed main cable The qualified rate of the saddle is low, and the processing cost is high

Embodiment 1

[0029] see figure 2 , image 3 , Figure 4 , Figure 5 with Image 6 As shown, the present invention includes a cable saddle body 1 and a back cable anchor 2 with a split structure.

[0030] Wherein, the cable saddle body 1 is mainly composed of side-span side 11 and middle-span side 12 of the split structure, which are locked together by a plurality of locking bolts on the joint surface of the middle part. The side span side 11 and the mid-span side 12 of the cable saddle body 1 have through saddle grooves, and saddle groove wall panels stand upright on both sides of the saddle groove, and the top profile of the saddle groove wall panels on each side is basically arched. Curved lines.

[0031] The inner side of the saddle wall plate on each side of the cable saddle body 1 is provided with a limit groove 14 in a sinking manner, and the limit groove 14 on each side is located at the upper part of the saddle wall plate on the mid-span side 12 close to the middle joint surf...

Embodiment 2

[0037] The invention includes a split-structure cable saddle body and a back cable anchor.

[0038] Among them, the cable saddle body is mainly formed by locking the side-span side and the middle-span side of the split structure through a plurality of locking bolts on the joint surface of the middle part. The side span side and the middle span side of the cable saddle body have through saddle grooves, and there are saddle groove wall panels upright on both sides of the saddle groove, and the top profile of the saddle groove wall panels on each side is basically an arched arc shape. Wire.

[0039] The outer side of the saddle groove wall plate on each side of the cable saddle body is provided with a limit groove in a sunken manner. There are multiple bolt holes arranged in multiple rows and columns on the wall plate of the groove, and two bolt holes are arranged on the wall plate of the saddle groove in the limit groove on each side corresponding to the arrangement track of th...

Embodiment 3

[0045] Other contents of this embodiment are the same as those of Embodiment 1 or 2, except that the cable saddle body is an integral structure, that is, the side span side and the middle span side are integrally formed.

Abstract

The invention discloses a main cable saddle of an assembled back cable structure. The main cable saddle comprises a cable saddle body and a back cable anchor body which are both of a separate structure, wherein back cable supports on the two sides of the back cable anchor body are fixed to corresponding saddle groove wall plates on the two sides of the cable saddle body through a plurality of locking bolt pairs respectively. According to the particularity of the main cable saddle of the back cable structure, the cable saddle body and the back cable anchor body are separately formed in the separate structure at first and then integrally assembled and formed by a plurality of high-strength locking bolt pairs, so that not only is implementation of the structural strength and functions of themain cable saddle of the back cable structure ensured, but also the influence of the back cable anchor body on a machining process of the cable saddle body is effectively eliminated. Therefore, the main cable saddle of the back cable structure can be easily, conveniently and efficiently machined and formed; the machining quality is reliable, the technical requirements of a back cable type suspension bridge are met, and the main cable saddle is economical and practical.

Description

technical field [0001] The invention relates to a cable saddle of a suspension bridge, in particular to a main cable saddle of an assembled back cable structure. Background technique [0002] In the design of suspension bridges, it is required that the horizontal resultant force of the main cable at the top of the tower should be zero under the action of permanent load, so as to calculate the force of the main cable of the side span part and the main cable of the middle span part. Usually, the calculated force of the main cable in the side-span part and the force of the main cable in the mid-span part are not equal, and sometimes there is a big difference; however, for the design of the main cable, no matter whether it is in the side-span part, It is still in the mid-span part, and the safety factor is the same, which will inevitably lead to a larger force-bearing area on the side where the main cable is stressed. When the force is applied, it is necessary to add a cable st...
