Suspension bridge anti-skidding cable clamp

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

technical field [0001] The invention relates to a cable clamp for a suspension bridge, in particular to an anti-slip cable clamp for a suspension bridge. Background technique [0002] In the structure of the suspension bridge, the cable clamp is the connection between the main cable and the suspension cable, which is used to transmit the static load and dynamic load of the bridge deck to the main cable, and is an important stress-bearing member. Since the linearity of the main cable is a parabola or a suspension line, the angle between the main cable and the sling cannot form a right angle. In this case, the tension and horizontal component of the sling cannot be vertical and cannot be balanced. The horizontal component force will be distributed linearly along the main cable through the cable clamp, which will cause the cable clamp to have a tendency to slide linearly along the main cable, which will affect the safety of the suspension bridge. For this reason, the tradition...

Problems solved by technology

This method not only requires high-strength bolts to have extremely high locking force, but also requires the structural strength of the cable clamp to be high enough to adapt to the high-strength locking force, which increases the difficulty of manufacturing the cable clamp and increases the number of manufacturing materials. Therefore, the manufacturing cost of the whole cable clamp is increased; in addition, this method makes the installation and operation of the cable clamp difficult, the labor intensity of the workers is heavy, and the safety and reliability are poor.
