Description

Replaceable full-sealed cable clamp structure

Technical Field

The invention relates to a cable clamp structure, in particular to a replaceable full-sealed cable clamp structure. Belongs to the field of bridges and structures.

Background

In the prior art, a main cable of a suspension bridge is directly connected with the main cable through a bolt by using a cable clamp, the cable clamp and the main cable are sealed by filling high polymer materials such as butyl rubber, polysulfide sealant and the like, and the main cable is exposed to the outside, exposed to the sun and rain for a long time and has severe working conditions, so that the sealing protection system of the conventional cable clamp is easy to age and lose efficacy, the aged cable clamp easily causes external rainwater to enter the inside of the main cable, and the protection effect of the main cable is unsatisfactory. Once rainwater enters the main cable from the gap at the joint of the cable clamp to cause corrosion, the service life of the main cable is seriously influenced.

In addition, the cable clamp is a key component for connecting the main cable and the bridge deck sling, the cable clamp in the prior art is generally connected by two semi-ring clamps through bolts, the pin holes of the cable clamp of the suspension bridge are in dynamic load abrasion for a long time, once the pin holes are abraded, the stress performance and the service life of the sling are seriously influenced, and the cable clamp and the main cable are sealed by filling high polymer materials, so that the cable clamp is difficult to replace after being damaged or the main cable is corroded.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a replaceable full-sealed cable clamp structure aiming at the prior art, which improves the sealing property of the cable clamp and facilitates the replacement of the cable clamp.

The technical scheme adopted by the invention for solving the problems is as follows: the utility model provides a removable totally enclosed cable clamp structure, mainly includes outer cable clamp and sealed cowling, outer cable clamp includes two semi-ring clamps, and two semi-ring clamp cooperation butt joints the back, can form the main push-towing rope mounting hole that is used for cartridge main push-towing rope between two semi-ring clamps, and the main push-towing rope is installed back in the cable clamp, then through screw rod and nut with two semi-ring clamp locking set up the sealed cowling between outer cable clamp and the main push-towing rope, the main push-towing rope that has the sealed cowling arranges the main push-towing rope mounting hole that outer cable clamp formed in.

Preferably, the sealing cover is of a butt-joint structure, the two half sealing covers are embraced on the surface of the main cable, and the joint of the two halves is locked through a screw and a nut.

Preferably, the half-and-half joints of the outer layer cable clamp and the half-and-half joints of the sealing cover are staggered at a certain included angle

Preferably, the included angle of the half-and-half joint of the outer layer cable clamp and the sealing cover is greater than 0 degree and smaller than or equal to 90 degrees.

Preferably, the included angle of the half-and-half connection part of the outer layer cable clamp and the sealing cover is 90 degrees.

Preferably, a plurality of silicone rubber rings are arranged between the sealing cover and the main cable.

Compared with the prior art, the invention has the advantages that:

1) the original integral cable clamp is converted into a split type, the inner part adopts a full-sealing structure, and the outer layer is used for holding and connecting;

2) the innovation point of the structure is as follows: (1) the novel internal cable clamp adopts a butt-joint type sealing cover structure, and solves the sealing problem of the two ends and the joint of the two halves of the original structure; (2) the outer layer cable clamp and the inner layer sealing cover are staggered by 90 degrees in half-and-half structure, the connection stress function is ensured through holding, and the two ends of the outer layer cable clamp and the inner layer sealing cover do not need to be sealed; (3) the outer layer cable clamp can be replaced together with the sling according to actual use requirements due to the fact that the outer layer cable clamp does not have a combination and sealing structure with the main cable, the problems that the main cable is secondarily watered, the position is dislocated and the like in the replacement of the traditional cable clamp are solved, and the replacement of the cable clamp is really realized.

Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1-5, the present embodiment provides a replaceable fully-sealed cable clamp structure, which mainly includes an outer-layer cable clamp 1 and a sealing cover 2, where the outer-layer cable clamp 1 includes two half-ring clamps, and after the two half-ring clamps are mated and butted, a main cable mounting hole for inserting a main cable can be formed between the two half-ring clamps, and after the main cable is mounted in the cable clamp, the two half-ring clamps are locked by a screw and a nut.

In order to improve the sealing effect between the outer layer cable clamp 1 and the main cable, a sealing cover 2 is arranged between the outer layer cable clamp 1 and the main cable, the sealing cover 2 is of a butt-joint structure, the two sealing covers are embraced on the surface of the main cable, the joint of the two sealing covers is locked by a screw and a nut, and then the main cable with the sealing cover 2 is arranged in a main cable mounting hole formed by the outer layer cable clamp 1.

The half-and-half joint of outer cable clamp 1 and the half-and-half joint of sealed cowling 2 between be certain contained angle staggered arrangement, prevent that the rainwater from directly getting into the main push-towing rope by the half-and-half joint of outer cable clamp 1 and sealed cowling 2, the contained angle of the half-and-half joint of outer cable clamp 1 and sealed cowling 2 is more than 0 less than or equal to 90, and preferred contained angle is 90.

In order to prevent rainwater from entering the main cable from two ends of the cable clamp, a plurality of silicon rubber rings 4 are arranged between the sealing cover 2 and the main cable 3, so that the cable clamp structure has a sealing effect in the length direction of the main cable.

In addition to the above embodiments, the present invention also includes other embodiments, and any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of the claims of the present invention.
