Abstract

A suspension bridge anti-skidding cable clamp comprises a first half ring body and a second half ring body, wherein the first ring body and the second half ring body are matched with each other from left to right or from top to bottom. Two ends of an annual outline of the first half ring body are provided with connecting steps and two ends of an annual outline of the second half ring body are provided with connecting steps, and the connecting steps of the first half ring body and the second half ring body are provided with a plurality of bolt holes which correspond to each other. The first half ring body and the second half ring body are connected with each other through high-intensity bolts. Anti-skidding structures are respectively arranged on the inner wall surfaces of the first half ring body and the second half ring body and each anti-skidding structure is at least one anti-skidding groove or at least one anti-skidding protruding tooth. After the anti-skidding structures are installed on a main cable, locking friction between the cable clamp and the main cable is greatly increased, the cable clamp is prevented from skidding on the main cable, and therefore installation reliability of the cable clamp on the main cable improved and a suspension bridge is safe. In addition, the suspension bridge anti-skidding cable clamp can effectively reduce level of manufacture difficulty, decrease manufacture materials, control manufacture cost, benefit installation operation on the main cable, relieve labor intensity of workers and is good in practicability, safe and reliable.

Description

Suspension bridge antiskid cord clip
Technical field
The present invention relates to the cord clip of suspension bridge, specifically a kind of suspension bridge antiskid cord clip.
Background technology
In the structure of suspension bridge, cord clip is the connector between main push-towing rope and hoist cable, passes to main push-towing rope as static load and dynamic load with bridge floor, is important primary structure member.The linearity of setting up due to main push-towing rope is parabola or outstanding line, make the angle between main push-towing rope and hoist cable can't form the right angle, like this, the pulling force of hoist cable also just can't form vertical with horizontal component, can not balance, the horizontal component of hoist cable can be by the linear dispersed of cord clip along main push-towing rope, thereby cause cord clip to produce the trend that glides along main cable linear, affects suspension bridge safety.For this reason, traditional solution is, the cord clip of two hemizonids is locked by high-strength bolt, utilizes frictional force between locking cord clip and main push-towing rope to overcome the horizontal component of downslide.The method not only requires high-strength bolt to have high coupling mechanism force, and require the structural strength of cord clip enough high, to adapt to high-intensity coupling mechanism force, this just causes the manufacture difficulty of cord clip to increase, materials being fabricated increases, thereby the manufacturing cost of whole cord clip is raise; In addition, the method makes cord clip fitting operation difficulty, and labor strength is heavy, and security reliability is poor.
Summary of the invention
The object of the invention is to: for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to manufacture, low cost of manufacture, fitting operation convenient, with main push-towing rope reliable lock, safe suspension bridge antiskid cord clip.
the technical solution used in the present invention is: a kind of suspension bridge antiskid cord clip, comprise a left side, the right or up, under the first hemizonid and the second hemizonid that are combined together, the first hemizonid be connected the circular contour two ends of hemizonid and be provided with the connection step, the first hemizonid be connected the connection step of hemizonid and be provided with the bolt hole of a plurality of mutual correspondences, the first hemizonid and the second hemizonid link together by high-strength bolt, the internal face of described the first hemizonid and the second hemizonid is respectively equipped with the antiskid structure, this antiskid structure is at least one antiskid groove or at least one antiskid double wedge.
Described antiskid double wedge is arc shape, is fixed on the internal face of the first hemizonid and the second hemizonid in the mode of inlaying or weld.Or described antiskid double wedge is arc shape, antiskid double wedge and the first hemizonid and the second hemizonid one-shot forming.
The cross section center line extension line of described antiskid double wedge is vertical with the cord clip axis or tilt.
Described antiskid groove is arc shape, and the cross section center line extension line of antiskid groove is vertical with the cord clip axis or tilt.
The bottom of described cord clip is provided with downward extended engaging lug, has pin-and-hole on engaging lug, and engaging lug connects hoist cable by bearing pin.
The top of described cord clip is provided with the groove that rides that connects hoist cable.
The invention has the beneficial effects as follows: by the antiskid structure of groove or double wedge is set at the cord clip internal face, make be arranged on main push-towing rope after, and the locking frictional force between main push-towing rope can increase greatly, prevent from making cord clip slippage on main push-towing rope because of the horizontal component of hoist cable, improve the installation reliability of cord clip on main push-towing rope, ensure suspension bridge safety; In addition, by the setting of antiskid structure, can effectively reduce the manufacture difficulty of cord clip, reduce materials being fabricated, control manufacturing cost, convenient fitting operation on main push-towing rope alleviates labor strength, and practical, security reliability is high.
