Description

Locking pin joint formula cable clip that moves

Technical Field

The utility model relates to a suspension bridge's cable clip specifically is one kind and can effectively prevent to take place to warp when the labour on the main push-towing rope and take place to become flexible to take off the air and/or the vice tensile deformation of closure bolt and not hard up pin joint formula cable clip.

Background

In the structure of the suspension bridge, the cable clamp is a conversion locking part for fixedly connecting a sling/suspender connected with the bridge deck on a main cable, namely, a non-right-angle structure matched included angle is formed between the main cable of a parabola/catenary structure and the vertically downward sling/suspender through the cable clamp, and the dynamic load and/or static load of the bridge deck acts on the main cable through the sling/suspender and the cable clamp. It can be seen that the cable clamp is one of the key stressed components in a suspension bridge structure.

In a suspension bridge construction, the vertical pull down force of the suspension cable/boom acts on the main cable of the parabolic/catenary configuration via the clamp, so that the vertical pull down force exerted by the clamp results in a component force in the direction of the main cable profile, and the clamp has a tendency to slide down on the main cable profile. In order to overcome the downward sliding tendency, the cable clamp is generally designed into a split structure, and a single arc-shaped cable clamp upper half and a cable clamp lower half, wherein the cable clamp upper half and the cable clamp lower half are combined into an annular structure capable of clamping and hooping the main cable through circumferential butt joint of two groups of high-strength locking bolt pairs, so that the cable clamp upper half and the cable clamp lower half generate a friction force on the main cable, which is enough to resist downward sliding force along the line shape of the main cable, by using the circumferential locking clamping force of the high-strength locking bolt pairs.

In the suspension bridge structure, the cable clamp is divided into a straddle type cable clamp and a pin joint type cable clamp according to different connection structural forms between a sling/suspender and the cable clamp. The riding type cable clamp is characterized in that a riding groove with an inward concave structure is arranged on the periphery of the outer wall of the cable clamp, and a sling capable of being wound and deformed is ridden on the periphery of the cable clamp. The pin joint type cable clamp is characterized in that a convex lug plate with a pin hole is arranged on the periphery of the cable clamp, a sling/suspender is in pin joint with the lug plate of the cable clamp through a pin shaft, and the common pin joint type cable clamp is formed by forming the lug plate at the bottom of the lower half of the cable clamp (usually one lug or two lugs which are arranged side by side at intervals, wherein the lug plate is positioned at the circumferential central area of the lower half of the cable clamp).

In the suspension bridge structure, the upper half of a cable clamp and the lower half of the cable clamp of a pin joint type cable clamp form a top-to-bottom matching structure on a main cable through two groups of locking bolt pairs, the upper half of the cable clamp is matched with the upper side area of the periphery of the main cable, the lower half of the cable clamp is matched with the lower side area of the periphery of the main cable, two butt joints of the two groups of locking bolt pairs in circumferential butt joint are matched with the two side areas of the periphery of the main cable, and an ear plate protruding downwards at the bottom of the lower half of the cable clamp is in pin joint with the upper end of a sling/suspender through a pin shaft so as to connect the main cable of a parabola/suspension chain structure. However, the pin joint cable clamp has the following stress conditions in the service process, which influence the loosening phenomenon of the main cable:

the vertical downward pull force generated by the sling/hanger rod acts on the ear plate of the lower half of the cable clamp, the lower half of the cable clamp generates accumulated fatigue and deforms along with the increase of the service time, the deformed lower half of the cable clamp generates a tendency of falling and loosening on the surface of the lower area of the periphery of the main cable ring along with the increase of the tendency of falling and loosening;

the vertical downward pulling force generated by the sling/boom acts on the lower half of the cable clamp, and acts on the upper half of the cable clamp through the two sets of locking bolt pairs, and as the downward pulling force is accumulated, the axial pulling force of the locking bolt pairs of the upper half of the circumferentially butted and combined cable clamp and the lower half of the cable clamp is increased, so that the locking bolt pairs are stretched, the stress section is reduced, and the condition is directly represented that the circumferentially butted and combined structure of the upper half of the cable clamp and the lower half of the cable clamp is loosened.

The single action or the synergistic action of the stress state finally causes the pin joint type cable clamp to loosen on the main cable, the friction force originally used for resisting the downward sliding force is reduced, the pin joint type cable clamp is easy to generate downward sliding displacement which influences the safety of the suspension bridge on the main cable, and the problem needs to be solved.
