Description

Technical Field

[0001] This utility model relates to the field of cable clamp ring joint sealing technology, specifically to a cable clamp ring joint sealing device for suspension bridge main cables. Background Technology

[0002] A suspension bridge, also known as a suspension bridge, is a bridge whose superstructure consists mainly of cables suspended from towers and anchored to both banks. The geometry of the cables is determined by the equilibrium of forces and is generally close to a parabola. Many hangers hang from the cables to support the bridge deck. Stiffening beams are often installed between the bridge deck and the hangers to form a combined system with the cables to reduce deflection caused by loads. The main cable is the most important load-bearing structure of a suspension bridge and bears the weight of the bridge as well as various impacts from wind, rain, vehicles, etc. The load-bearing capacity of the main cable is transferred through cable clamps installed on the main cable. The cable clamps are structural members, and when they are installed, bolts pass through the cable clamp structure to tightly grip the cable clamps onto the main cable.

[0003] To prevent rust and corrosion of the main cable structure, materials such as paint, protective paste, protective putty, fiberglass, and protective adhesive are generally used to form a sealed rainwater-isolated structural layer. After construction, these structural layers are brittle materials without extensibility. Due to reasons such as loose bolts, main cable vibration, main cable deformation, and insufficient friction, relative slippage often occurs between the cable clamp and the main cable. When the cable clamp slips, the relative sliding between the cable clamp and the main cable, with one end being pulled apart and the other end being compressed, damages the original protective structure. This kind of slippage is unacceptable in bridge structures and will cause many adverse phenomena: stress changes and structural deformation, gaps and leaks in the structure leading to internal steel wire corrosion. All of these situations will ultimately endanger the safety of the bridge. Therefore, there is an urgent need for a suspension bridge main cable clamp ring joint sealing device to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to provide a sealing device for the main cable clamp ring joint of a suspension bridge, which has the advantages of good sealing effect and anti-slip properties, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspension bridge main cable clamp ring seam sealing device, comprising a cable clamp body, an anti-slip sealing component, a sealing component, and a second fixing cover. The anti-slip sealing component is disposed on the top of the cable clamp body, the sealing component is disposed on the bottom of the cable clamp body, and the second fixing cover is disposed on the top of the anti-slip sealing component. The anti-slip sealing component includes a first moving block, a first turntable, a first sliding groove, a first sliding block, a first threaded rod, a moving rod, an arc-shaped seat, an anti-slip corrugated block, a connecting rod, a fixing block, a second sliding groove, a second sliding block, and a spring. The sealing component includes a first fixing cover, a second moving block, a third sliding groove, a third sliding block, a second threaded rod, and a second turntable.

[0006] Furthermore, the first movable block is fixedly installed on the top of the cable clamp body, the first groove is formed inside the first movable block, the first slider slides in the inner cavity of the first groove, and the first turntable is disposed on the front of the first movable block.

[0007] Furthermore, the first threaded rod rotates inside the first slider via a thread, and the front of the first threaded rod extends through to the front of the first moving block and is fixedly connected to the back of the first turntable. The moving rod is fixedly installed on the back of the first slider, and the arc-shaped seat is fixedly installed on the back of the moving rod.

[0008] Furthermore, the second slide grooves are all opened on both sides inside the arc-shaped seat, the second slider slides inside the second slide groove, the fixing block is fixedly installed on the front of the second slider, and a spring is fixedly installed in the inner cavity of the second slide groove on the side relatively close to the second slider.

[0009] Furthermore, a connecting rod is fixedly installed on the side of the fixed block that is relatively close to each other, and an anti-slip corrugated block is fixedly installed on the side of the connecting rod that is relatively close to each other. The top of the moving rod is fixedly connected to the bottom of the second fixed cover, and the second moving block is fixedly installed on the bottom of the cable clamp body.

[0010] Furthermore, the second turntable is disposed on the front of the second moving block, the third slide groove is formed inside the second moving block, and the third slider slides inside the third slide groove.

[0011] Furthermore, the second threaded rod rotates inside the third slider via a thread, and the output shaft of the second threaded rod passes through the front of the second moving block and is fixedly connected to the back of the second turntable. The first fixed cover is fixedly installed at the bottom of the third slider.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention uses a cable clamp body to fix the main cable, and an anti-slip sealing component to seal the connection of the cable clamp body, preventing displacement in severe weather and preventing water ingress through gaps. A sealing component and a second fixing cover protect the outer surface of the cable clamp body. During fixing, rotating the first turntable drives the first threaded rod to rotate, causing the first slider to move the moving rod, the arc-shaped seat, and the second fixing cover to one side. Then, based on the gap between the cable clamp body and the main cable, the anti-slip corrugated block moves inward, causing the connecting rod, the fixing block, and the second slider to move inward. Finally, the arc-shaped seat moves the anti-slip corrugated block to one side. The clamp enters the gap between the clamp body and the main cable, moves to the designated position, and reinforces the clamp body. After reinforcement, the anti-slip corrugated block prevents displacement and seals the gap in the clamp body. Finally, the second turntable is rotated, which drives the second threaded rod to rotate, causing the third slider to move the first fixing cover to one side. The first and second fixing covers prevent rainwater from splashing onto the surface of the clamp body. This method has the advantages of good sealing effect and anti-slip, solving the problem of relative slippage between the clamp and the main cable, the relative sliding between the clamp and the main cable when the clamp slips, and the structural displacement causing gaps and water leakage that leads to corrosion of the internal steel wires.
