Description

Technical Field

[0001] The utility model relates to the technical field of suspension bridges, in particular to a suspension bridge retaining device. Background Art

[0002] A suspension bridge, also known as a suspension bridge, refers to a bridge that uses cables (or steel chains) suspended from towers and anchored on both banks (or both ends of the bridge) as the main load-bearing components of the upper structure. The geometric shape of the cables is determined by the balance of forces and is generally close to a parabola. Many hangers are hung from the cables to suspend the bridge deck. Stiffening beams are often set between the bridge deck and the hangers to form a combined system with the cables to reduce the deflection caused by the load.

[0003] The cable clamp of a suspension bridge is a key load-bearing component in the upper structure of a suspension bridge. A suspension bridge is mainly composed of main cables, side cables and oblique cables, and the cable clamp of a suspension bridge is an important component used to fix these cables. The cable clamp of a suspension bridge can bear huge tension, and make the cables tightly connected, and maintain the stability and safety of the structure. The role of the cable clamp is similar to that of a clamp. It needs to have sufficient strength and rigidity so that it does not slide when the main cable is subjected to tension, and it must also be able to flexibly adapt to the expansion and contraction changes of the main cable. In addition, the cable clamp also bears the weight of the bridge deck system and other live loads, which is crucial to the safety and durability of the suspension bridge.

[0004] The cable clamps of suspension bridges are mostly in the form of two halves, but in the current technology, the cable clamps do not have the function of initial positioning during installation. The heavy cable clamps require manual placement and positioning by installation workers throughout the entire process. In addition, the installation height of the main cable is affected, which makes the installation work more cumbersome and difficult. In addition, when installing bolts and nuts to fix the cable clamps, shaking or displacement is very likely to occur, causing the installed cable clamps to deviate from the predetermined position, affecting the installation accuracy.

[0057] Optionally, the hoisting mechanism 4 includes a load-bearing plate 41, a fixed point block 42 and a hand chain hoist 43;

[0058] The load-bearing plate 41 is installed between the left frame 31 and the right frame 32, and the load-bearing plate 41 is located at the top of the left frame 31 and the right frame 32. The two fixed-point blocks 42 are arranged at intervals on the bottom surface of the load-bearing plate 41. The two hand chain hoists 43 are hoisted on the two fixed-point blocks 42 respectively. The hand chain hoist 43 is an existing manual lifting machine that is simple to use and easy to carry.

[0059] The two hand winches 43 are located directly above the cable clamp 2. After the walking mechanism 3 moves to the predetermined installation position of the cable clamp 2, the upper part 21 is first buckled on the main cable 1, and then the lower part 22 is taken out, and the lifting chains of the two hand winches 43 are wrapped and tied around the lower part 22.

[0062] The lower arc-pressing plate 8 is tightly attached to the upper half 21, and the hydraulic telescopic rod 7 is in a retracted state under normal conditions, that is, the lower arc-pressing plate 8 is not attached to the upper half 21. After the upper half 21 is buckled on the main cable 1 and before the hoisting mechanism 4 lifts the lower half 22, the hydraulic telescopic rod 7 is pulled down to extend it until the lower arc-pressing plate 8 is tightly attached to the upper half 21, and a downward force is applied to the upper half 21, thereby pressing the upper half 21 down on the main cable 1 to prevent the upper half 21 from moving, thereby preventing the upper half 21 from shifting during subsequent installation, and at the same time avoiding the displacement of the upper half 21 due to the collision between the lower half 22 and the upper half 21 when hoisting, thereby ensuring that the cable clamp 2 is accurately installed at the predetermined position, ensuring the installation accuracy and quality.

[0063] Optionally, the towing mechanism 6 includes an elastic sleeve 61, a horizontal platform 62, a winch 63, a round rod 64 and a towing rope 65;

When the walking mechanism 3 moves, the elastic sleeve 61 is loosened, so that the towing mechanism 6 can move along the main rope 1 with the movement of the walking mechanism 3, or when When the length of the traction rope 65 allows, the traction rope 65 is gradually loosened through the winch 63 as the traveling mechanism 3 moves. After the traveling mechanism 3 reaches the specified position, the winch 63 is locked, and the traction rope 65 and the round rod 64 are used to pull the left frame 31 and the right frame 32, thereby preventing the two main rollers 33 from continuing to roll forward on the main rope 1, thereby preventing the traveling mechanism 3 from moving abnormally during the subsequent installation process of the cable clamp 2 and affecting the installation of the cable clamp 2, thereby ensuring the smooth installation of the cable clamp 2 while ensuring the installation accuracy.

[0065] Optionally, the side connection portion 5 includes a positioning bar 51 and a side roller 52;

[0067] The two side rollers 52 are connected to the main cable 1 from the left and right sides respectively. When the walking mechanism 3 moves, the four side rollers 52 roll forward along the main cable 1 synchronously. The rolling relationship between the four side rollers 52 and the main cable 1 is utilized to increase the rolling connection points between the suspension bridge retaining device and the main cable 1, thereby reducing the load on the main roller 33, greatly improving the smoothness when walking on the main cable 1, and ensuring the performance of the suspension bridge retaining device.

[0068] Optionally, the side connection portion 5 further includes a base block 53, a hole 54 and a locking bolt 55;

The two locking bolts 55 are respectively inserted into the two groups of positioning strips 51 and the two base blocks 53 through the holes 54. When the thickness of the main rope 1 changes, the locking bolts 55 are taken out and the position of the positioning strips 51 is adjusted until the four side rollers 52 are connected to the main rope 1. Then, the locking bolts 55 are reinserted into the corresponding holes 54. The locking of the positioning strips 51 is restored by relying on the locking bolts 55 and the base blocks 53, so that the side connection part 5 can adapt to main ropes 1 of different sizes, thereby greatly improving the applicability.

[0070] Optionally, a suspension bridge retaining device further includes a pull rod 9 and a guide rod 10;

[0071] The two pull rods 9 are installed between the ends of the left frame 31 and the right frame 32 to lock the ends of the left frame 31 and the right frame 32, thereby enhancing the overall firmness; the two pull rods 9 are detachably installed to ensure that the suspension bridge fixing device can be removed from the main cable 1, and the two soft guide rods 10 are arranged on the upper half 21 and the lower half 22. A small part of the two guide rods 10 is slightly larger than the threaded holes on the lower half 22 and the upper half 21, and the remaining parts are slightly smaller than the threaded holes on the lower half 22 and the upper half 21. Before hoisting the lower half 22, the two guide rods 10 are slightly larger than the threaded holes on the lower half 22 and the upper half 21. The parts are all inserted into the two threaded holes at the opposite vertices on the lower half 22, and then the lower half 22 is hoisted. During the hoisting process, the two guide rods 10 are inserted into the corresponding threaded holes on the upper half 21, so that the position of the lower half 22 is corrected by relying on the two guide rods 10 during the hoisting process to ensure that the upper half 21 and the lower half 22 are accurately docked to prevent deviation, thereby ensuring the installation accuracy of the cable clamp 2. After the upper half 21 and the lower half 22 are docked, the other two threaded holes on the upper half 21 and the lower half 22 are first installed with bolts and nuts, and then the two guide rods 10 are removed to install the remaining bolts and nuts.
