Description
Technical field
The present invention relates to one and be applicable to main rope of suspension bridge accessory, particularly a kind of combined type cord clip of interchangeable main push-towing rope.
Background technology
Suspension bridge obtains fast development as the bridge that span is maximum in China, and is the major subjects that countries in the world engineers and technicians study as the main push-towing rope of suspension bridge lifeline always; Particularly the research of main push-towing rope corrosion-resistant is particularly paid attention to; If because funicular system corrodes, consequence is inconceivable; In order to the safety of the safety and line structure that ensure bridge, anti-corrosion protection must be carried out to cable, the limitation be familiar with in view of us and the anticorrosion research of main rope of suspension bridge also do not achieve satisfactory results, therefore, many bridge cables are had still to rely on the mode of changing rope to solve the anticorrosion of bridge cable and safety high at present; In the structural system of suspension bridge, my company of anchorage system has developed interchangeable, and is successfully applied to Yangluo Highway Bridge over Yangtze River in Wuhan City etc.; What therefore will solve the main push-towing rope of suspension bridge changes Suo Wenti, must have cord clip and the line structure of interchangeable main push-towing rope; And existing cord clip as depicted in figs. 18-19, comprise out reeded upper Rope holder body 5, lower Rope holder body 6, being connected and composed for clamping large main push-towing rope 8 by high-strength bolt pair between upper Rope holder body 5, lower Rope holder body 6, therefore will change cable body, is almost impossible.
The applicant had once applied for a kind of " cord clip of interchangeable main push-towing rope " last year, but its form of structure is single, and it is comparatively large that direction across bridge takies width, can't meet the needs of all kinds suspension bridge.
Summary of the invention
The object of the present invention is to provide and be a kind ofly applicable to the combined type cord clip that main rope of suspension bridge changes the interchangeable main push-towing rope of rope, adopt the combined type cord clip of this interchangeable main push-towing rope namely can change the main push-towing rope of suspension bridge easily, Suo Wenti is changed with what solve main rope of suspension bridge, and then solve the anticorrosion and safety high of main rope of suspension bridge, simultaneously, the combined cable clamping structure of this interchangeable main push-towing rope is various, can meet the requirement of multi-form bridge main push-towing rope cloth rope.
For solving the problem, the technical scheme that the present invention takes is: a kind of combined type cord clip of interchangeable main push-towing rope, the combined cable folder of this interchangeable main push-towing rope comprises 2n side Rope holder body, 1 middle cable clamp, each side Rope holder body described be have groove I, both sides have and connect the separation Rope holder body of step, the both sides of side Rope holder body connect the screwed hole or the circular hole that step have m installation high-strength bolt; Described middle cable clamp is the Rope holder body that both sides have n groove II respectively, screwed hole or the circular hole of m installation high-strength bolt is had in each groove II both sides of middle cable clamp, middle cable clamp bottom is the otic placode be connected with hoist cable, otic placode has the pin-and-hole be connected with hoist cable, under using state, 2n side Rope holder body is connected and composed with the middle cable clamp with 2n groove II respectively by high-strength bolt pair has 2n for clamping the combination cord clip of the through hole of main push-towing rope; The span of above-mentioned m, n is: m, for being more than or equal to 2, is less than or equal to the integer of 100, and n, for being more than or equal to 2, is less than or equal to the integer of 50.
Its further technical scheme is: the groove I of the side Rope holder body of the combined type cord clip of described interchangeable main push-towing rope is similar with size to the shape of the groove II of middle cable clamp, what be combined into is circular hole, slotted eye or shape hole, X limit for clamping the through hole of little main push-towing rope, X, for being more than or equal to 4, is less than or equal to the integer of 50.
Its further technical scheme is: the transverse width of the middle cable clamp of the combined type cord clip of described interchangeable main push-towing rope or equally wide or up-narrow and down-wide up and down; Or it is wide at the top and narrow at the bottom; Or it is wide in the middle part of middle cable clamp, narrow up and down.
Its further technical scheme be: the center line of n the groove II that the both sides of the middle cable clamp of the combined type cord clip of described interchangeable main push-towing rope have respectively and n the through hole for clamping little main push-towing rope that side Rope holder body groove I forms is straight line or curve.
Its further technical scheme or: the seam crossing of middle cable clamp both sides respectively and between n side Rope holder body of the combined type cord clip of described interchangeable main push-towing rope is straight line or zigzag broken line.
Its further technical scheme or: the otic placode that middle cable clamp bottom is connected with hoist cable or be connected with middle cable clamp makes, or is connected with middle cable clamp after making separately.
Owing to taking above technical scheme, the combined cable fixture of the interchangeable main push-towing rope of the present invention has following beneficial effect:
1. can realize single large main push-towing rope being split into the many little main push-towing ropes be arranged in order in vertical direction to clamp, by taking separately side Rope holder body apart one by one after suspension bridge builds up, little main push-towing rope is checked, safeguards and changed, thus realizes the intact object of main push-towing rope retention.
2. be arranged into left and right two-row structure by little main push-towing rope in vertical direction, make little main push-towing rope take width at direction across bridge and diminish, be conducive to hoist cable design and arrange, make whole bridge type more attractive in appearance.
3. main push-towing rope is broken after many little main push-towing ropes, makes main push-towing rope miniaturization, make and construction equipment miniaturization, construct, easy to maintenance.
