A replaceable fully sealed cable clamp structure

Abstract

The present invention relates to a replaceable fully sealed cable clamp structure, which mainly includes an outer cable clamp and a sealing cover. The outer cable clamp includes two half-ring clamps. After the two half-ring clamps are matched and docked, a main cable installation hole for inserting a main cable can be formed between the two half-ring clamps. After the main cable is installed in the cable clamp, the two half-ring clamps are locked by screws and nuts. A sealing cover is arranged between the outer cable clamp and the main cable. The main cable with the sealing cover is placed in the main cable installation hole formed by the outer cable clamp. The sealing cover is a mating structure. The two halves of the sealing cover are clasped on the surface of the main cable, and the joint of the two halves is locked by screws and nuts. The internal cable clamp of the present invention adopts a mating sealing cover structure to solve the sealing problem of the two ends and the joint of the two halves of the original structure; at the same time, it can be replaced together with the sling according to actual use needs, solving the problems of secondary water ingress and position dislocation of the main cable in the replacement of traditional cable clamps, and truly realizing the replaceable cable clamp.

Description

Technical Field

[0001] The invention relates to a cable clamp structure, in particular to a replaceable fully sealed cable clamp structure, belonging to the field of bridges and structures. Background Art

[0002] In the prior art, the main cable of the suspension bridge is directly bolted to the main cable with a cable clamp, and the cable clamp and the main cable are sealed by filling with high polymer materials such as butyl rubber and polysulfide sealant. Since the main cable is exposed to the outside world, exposed to the sun and rain for a long time, and the working conditions are bad, the sealing protection system of the existing cable clamp is prone to aging and failure, so that the aged cable clamp easily allows rainwater from the outside to enter the main cable, resulting in unsatisfactory protection effect for the main cable. Once rainwater enters the main cable from the gap at the cable clamp connection and causes erosion, it will seriously affect the service life of the main cable.

[0003] In addition, the cable clamp is a key component connecting the main cable and the bridge deck suspension cable. The cable clamp in the prior art generally uses two half-ring clamps connected by bolts. Since the cable clamp pin hole of the suspension bridge is in dynamic load wear for a long time, once the pin hole wears out, it will seriously affect the force-bearing performance and service life of the suspension cable. In addition, since the cable clamp and the main cable are sealed by filling polymer materials, the cable clamp is difficult to replace after it is damaged or the main cable is corroded. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a replaceable fully sealed cable clamp structure for the above-mentioned prior art, which improves the sealing performance of the cable clamp and facilitates the replacement of the cable clamp.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a replaceable fully sealed cable clamp structure, mainly comprising an outer cable clamp and a sealing cover, the outer cable clamp comprises two half-ring clamps, after the two half-ring clamps are matched and docked, a main cable installation hole for inserting the main cable can be formed between the two half-ring clamps, after the main cable is installed in the cable clamp, the two half-ring clamps are then locked by a screw and a nut, a sealing cover is arranged between the outer cable clamp and the main cable, and the main cable with the sealing cover is placed in the main cable installation hole formed by the outer cable clamp.

[0006] Preferably, the sealing cover is a double-jointed structure, the two halves of the sealing cover are engaged with the surface of the main cable, and the joint of the two halves is locked by a screw and a nut.

[0007] Preferably, the half connection of the outer layer cable clamp and the half connection of the sealing cover are arranged alternately at a certain angle.

[0008] Preferably, the angle between the outer cable clamp and the sealing cover at the half connection is greater than 0° and less than or equal to 90°.

[0009] Preferably, the angle between the outer layer cable clamp and the sealing cover at the connection point in half is 90°.

[0010] Preferably, a plurality of silicone rubber rings are provided between the sealing cover and the main cable.

[0011] Compared with the prior art, the advantages of the present invention are:

[0012] 1) Convert the original integral cable clamp into a split type, with a fully sealed structure inside and the outer layer used for clamping and connection;

[0013] 2) Innovations of this structure: (1) The new internal cable clamp adopts a double-sealed cover structure to solve the sealing problem at both ends and at the joint of the two halves of the original structure; (2) The outer cable clamp and the inner sealing cover are staggered 90° in half, and the connection force function is ensured by clamping, and the two ends do not need to be sealed; (3) Since the outer cable clamp does not have a joint and sealing structure with the main cable, it can be replaced together with the sling according to actual use needs, solving the problems of secondary water ingress and position displacement of the main cable in the replacement of traditional cable clamps, and truly realizing the replaceable cable clamp.

[0019] The present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, this embodiment provides a replaceable fully sealed cable clamp structure, which mainly includes an outer cable clamp 1 and a sealing cover 2. The outer cable clamp 1 includes two half-ring clamps. After the two half-ring clamps are mated, a main cable installation hole for inserting the main cable can be formed between the two half-ring clamps. After the main cable is installed in the cable clamp, the two half-ring clamps are locked by screws and nuts.

[0021] In order to improve the sealing effect between the outer cable clamp 1 and the main cable, a sealing cover 2 is arranged between the outer cable clamp 1 and the main cable. The sealing cover 2 is a double-jointed structure, and the two halves of the sealing cover are embraced on the surface of the main cable. The joint of the two halves is locked by a screw and a nut, and then the main cable with the sealing cover 2 is placed in the main cable installation hole formed by the outer cable clamp 1.

[0022] The half connection parts of the outer layer cable clamp 1 and the half connection parts of the sealing cover 2 are staggered at a certain angle to prevent rainwater from directly entering the main cable through the half connection parts of the outer layer cable clamp 1 and the sealing cover 2. The angle between the half connection parts of the outer layer cable clamp 1 and the sealing cover 2 is greater than 0° and less than or equal to 90°, and preferably the angle is 90°.

[0023] In order to prevent rainwater from entering the main cable from both ends of the cable clamp, a plurality of silicone 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.

[0024] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
