All-welded cable clamp

Abstract

An all-welded cable clamp is provided with a plurality of arc-shaped plates formed by steel plates, wherein the arc-shaped plates are sequentially combined and connected in the peripheral direction to form a cable hole in a surrounding manner; edges of at least two arc-shaped plates are connected in the peripheral direction; connecting lugs formed by steel plates are respectively arranged on outer walls of the two arc-shaped plates of which the edges are connected in the peripheral direction; each connecting lug mainly comprises an outer pressure-bearing plate, an inner pressure-bearing plate and a plurality of supporting rib plates which are welded to the outer wall of the corresponding arc-shaped plate; each outer pressure-bearing plate and the corresponding inner pressure-bearing plate are elongated, are separated from each other in the peripheral direction of the corresponding arc-shaped plate, and are welded to the outer wall of the corresponding arc-shaped plate in the length direction of the arc-shaped plate; the welded position of each inner pressure-bearing plate is close to the peripheral connected edge of the corresponding arc-shaped plate; the supporting rib plates of each connecting lug are successively separated from one another in the length direction of the corresponding arc-shaped plate, are arranged on the outer wall of the corresponding arc-shaped plate, and are positioned between the corresponding outer pressure-bearing plate and the corresponding inner pressure-bearing plate; three sides of each supporting rib are welded with the corresponding outer pressure-bearing plate, the corresponding arc-shaped plate and the corresponding inner pressure-bearing plate; and a plurality of bolt holes which correspond in pairs are formed in parts, which are staggered from the corresponding supporting rib plates, of each outer pressure-bearing plate and each inner pressure bearing plate.

Description

technical field [0001] The invention relates to a cable clamp, a stressed member of a suspension bridge, in particular to a fully welded cable clamp. Background technique [0002] The cable clamp is an important force-bearing component that directly transfers the static and dynamic loads of the bridge deck to the main cable in the suspension bridge, and its forming quality directly affects the stability and safety of the suspension bridge. [0003] For a long time, the cable clips used in suspension bridges have basically all adopted full-cast structures. In order to ensure the stress strength and molding quality of cast-molded cable clips, it has very high technical requirements for casting molding, especially heat treatment with great technical difficulty. Casting defects are prone to occur during the casting process, such as pores, shrinkage cavities, Shrinkage, sand inclusions, cracks and other defects lead to low casting pass rate and molding efficiency of the cable cl...

Problems solved by technology

However, due to the irregularity of the circumferential structure of the cable clamp, it cannot be formed by the general processing of high-performance steel plates into an arc or cylindrical structure, and it also involves welding and forming of various combined connection structures , such as "a welded combined cable clamp" disclosed in Chinese patent literature (publication number: CN204112221, publication date: January 21, 2015), this technology is formed by a welded combined structure of steel plates, which can effectively and reliably overcome all The steel plate welded cable clamp with cast structure cable clamp disadvantages; however, its welded forming structure still has technical deficiencies, which is mainly reflected in the connecting ears (ie pressure-bearing platform) that are butted on each side of its arc-shaped plate (ie half-ring body) ) has multiple independent door-shaped pressure-bearing components, the number of these door-shaped pressure-bearing components is consistent with the number of bolt pairs required for the docking part, that is, if ten bolt pairs are required, then there must be ten penetration bolts The door-shaped pressure-bearing component of the pair, this cable clamp structure will not only increase the difficulty of forming (mainly the difficulty of cutting and welding the plates composed of the pressure-bearing component), but also is not conducive to the improvement of forming efficiency, which will increase the manufacturing cost and further What's more, the overall rigidity of the connecting ear composed of multiple independent door-shaped pressure-bearing components is poor, and the door-shaped pressure-bearing components on the same connecting ear cannot carry superhigh pressure evenly, stably and reliably. Strong locking force, easy to cause safety hazards, poor reliability, safety and practicability, needs to be improved urgently
