Description

Technical Field

[0001] This utility model relates to cable clamps for suspension bridges, specifically, to an anti-slip self-sealing cable clamp. Background Technology

[0002] In suspension bridge engineering, cable clamps are key load-bearing components that connect the main cable of the suspension bridge to the suspenders that connect the bridge.

[0003] The cable clamps rely on the preload of the bolt group to tighten the main cable, and use the friction between the cable clamp and the main cable to overcome the horizontal component of the sliding force. When the frictional resistance is insufficient, the cable clamps will slip or come loose, thereby compromising the safety and stability of the entire bridge structure.

[0004] To ensure a safe and reliable connection between the cable clamp and the main cable, existing technology proposes an anti-slip cable clamp suitable for connecting the main cable and the cable clamp in suspension bridges. See the Chinese patent document published on May 8, 2013, entitled "Anti-slip Cable Clamp for Suspension Bridges." In this technology, at least one groove or at least one protrusion is provided on the inner walls of the first and second semi-rings to increase the friction between the main cable and the cable clamp during the clamping process, preventing slippage. However, the rigid structure such as the protrusion or groove makes direct rigid contact with the main cable surface. Firstly, this can easily damage the main cable during the clamping process. Secondly, it affects the smoothness of the connection between the inner wall of the cable clamp and the main cable, especially with the protrusion structure. Furthermore, the rigid structure such as the protrusion or groove makes it difficult to achieve a seal between the inner wall of the cable clamp and the main cable, requiring external sealing, which is detrimental to improving the internal sealing performance of the cable clamp. Utility Model Content

[0005] The technical objective of this utility model is to address the shortcomings of the prior art by providing an anti-slip self-sealing cable clamp that, under strong locking conditions, will not damage the main cable or hinder the clamping connection between the main cable and the cable clamp, and can achieve self-sealing and has good anti-slip performance.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An anti-slip self-sealing cable clamp includes multiple cable clamp halves that form a cable hole in the circumferential direction;

[0008] The inner wall of the cable clamp half is formed with circumferentially arranged insert grooves at least at both ends of the axial direction.

[0009] The mounting groove is fitted with a friction pad with a reinforced rubber composite material structure, and the friction pad protrudes from the inner wall surface of the cable clamp half.

[0010] The aforementioned technical measures, by setting embedding grooves at at least both ends of the inner wall of the cable clamp half and embedding friction pads of reinforced rubber composite material structure in the embedding grooves, can increase the friction between the cable clamp and the main cable, effectively prevent the cable clamp from slipping, improve the anti-slip performance of the cable clamp, and enhance the installation reliability of the cable clamp on the main cable. Simultaneously, during the clamping process between the main cable and the cable clamp, under strong locking conditions, it will neither damage the main cable nor hinder the normal connection between the main cable and the cable clamp, effectively reducing the impact on the flatness of the connection between the inner wall of the cable clamp and the main cable. The friction pads protrude from the inner wall surface of the cable clamp half, causing a certain deformation during the clamping process, better conforming to the surface of the main cable, making the contact pressure distribution more uniform, effectively preventing cable clamp slippage due to insufficient local pressure, and achieving a self-sealing effect, which is beneficial to improving the sealing performance inside the clamp and ensuring the stability and reliability of the connection between the cable clamp and the main cable.

[0011] Furthermore, the inner wall of the cable clamp half has 3 to 5 insert grooves arranged along the axial spacing.

[0012] The above-mentioned technical measures, by controlling the number of insert slots, can both meet the anti-slip performance required by the cable clamp and avoid affecting the structural rigidity of the cable clamp due to an excessive number of insert slots.

[0013] Furthermore, the mounting groove on the cable clamp half has a dovetail groove structure with a narrow opening and a wide bottom.

[0014] Correspondingly, the cross-section of the friction pad has a trapezoidal structure.

[0015] The above-mentioned technical measures, through the dovetail groove structure with a narrow opening and a wide bottom, match the friction pad with a trapezoidal cross-section, making the combination of the friction pad and the groove more stable and reliable, and effectively preventing the friction pad from loosening and falling off.

[0016] Furthermore, the mounting groove on the cable clamp half extends through to the mating surface of the cable clamp half at both ends;

[0017] Correspondingly, the friction pads embedded in the corresponding mounting grooves have both ends flush with the mating surfaces of the cable clamp halves.

[0018] In the above-mentioned technical measures, the mounting grooves on the cable clamp half extend to the mating surfaces of the cable clamp half at both ends. This facilitates the installation of friction pads and ensures that the mounting grooves can align and form a whole when adjacent cable clamp half parts are mated. The friction pads installed in the corresponding mounting grooves have both ends flush with the mating surfaces of the cable clamp half parts, so that the corresponding friction pads can cooperate with each other when the mounting grooves are mated, ensuring sealing performance.

[0019] Furthermore, the mounting groove on the clamp half has a width of 30-50mm and a depth of 10-20mm.

[0020] The above-mentioned technical measures, by controlling the width and depth of the groove, can not only meet the anti-slip performance required by the cable clamp, but also avoid affecting the structural rigidity of the cable clamp due to excessive groove width or depth.

[0021] Furthermore, the friction pad protrudes from the inner wall surface of the cable clamp half at a height of 2-5 mm.

[0022] The above-mentioned technical measures control the protrusion height of the friction pad relative to the inner wall surface of the cable clamp half, which can ensure that the friction pad is in close contact with the main cable and generates sufficient friction force, without hindering the tight binding of the main cable and the cable clamp.

[0023] Furthermore, the multiple cable clamp halves that make up the cable hole are joined together in a circular state in the circumferential direction. The fitting grooves and the friction pads fitted between adjacent cable clamp halves are in a one-to-one correspondence relationship, and the fitting grooves and the friction pads fitted in the one-to-one correspondence relationship are on the same circumference.

[0024] In the above-mentioned technical measures, the mounting grooves between adjacent cable clamp halves and the mounted friction pads are in a one-to-one correspondence, and the mounting grooves and the mounted friction pads are on the same circumference, so that the cable clamps form a complete structure in the circumferential direction, which is beneficial to improving the sealing performance.

[0025] Furthermore, the friction pad is fixed in place within the corresponding mounting groove using an adhesive structure.

[0026] In the above technical measures, the friction pad is fixed in the corresponding mounting groove with an adhesive structure, which makes the connection between the friction pad and the corresponding mounting groove more firm and stable, effectively preventing the friction pad from loosening or falling off, and improving the stability of the cable clamp.

[0027] Furthermore, the cable clamp half that makes up the cable hole consists of two parts.

[0028] Furthermore, at both axial ends of the cable clamp half, sealing grooves for connecting main cable sealing structures are respectively formed with stepped stop structures; and the sealing grooves are located on the outside of the corresponding mounting grooves.

[0029] The above-mentioned technical measures, by setting sealing grooves at both ends of the cable clamp half and the sealing grooves being located outside the corresponding mounting grooves, will not obstruct the tight clamping of the main cable and the cable clamp, thus further ensuring the sealing performance.

[0030] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0031] This invention increases the friction between the cable clamp and the main cable by setting embedding grooves at at least both ends of the inner wall of the cable clamp half and embedding friction pads of reinforced rubber composite material structure in the embedding grooves. This effectively prevents the cable clamp from slipping, improves the anti-slip performance of the cable clamp, and enhances the installation reliability of the cable clamp on the main cable. Simultaneously, during the clamping process between the main cable and the cable clamp, under strong locking conditions, it neither damages the main cable nor hinders the normal connection between the main cable and the cable clamp, effectively reducing the impact on the flatness of the connection between the inner wall of the cable clamp and the main cable. The friction pads protrude from the inner wall surface of the cable clamp half, causing them to deform during the clamping process, better conforming to the surface of the main cable and making the contact pressure distribution more uniform. This effectively prevents the cable clamp from slipping due to insufficient local pressure and achieves a self-sealing effect, improving the sealing performance inside the clamp and ensuring the stability and reliability of the connection between the cable clamp and the main cable.
